As shown in Figure 1, the present invention provides a car body for a packback car, which includes a body portion 1 and a support portion 4. The longitudinal ends of the support portion 4 are both provided with a connecting structure, wherein the connecting structure includes an upper hook 421 and an edge The lower round shaft 412c extends horizontally. The main body 1 is provided with an end connecting mechanism 22. The end connecting mechanism 22 includes an end connecting hook 221 and an end longitudinal support 222. The end connecting hook 221 forms an upwardly arranged hook opening. In the assembled state, the lower circular shaft 412c can be hung on the hook opening of the end connecting hook 221, and the upper hook 421 can be clamped to the end longitudinal support 222.

With this structure, there can be two connection points formed between the upper hook 421 and the end longitudinal support 222, the lower round shaft 412c and the end connecting hook 221 between the longitudinal ends of the holder 4 and the main body 1. The connection between the holder part 4 and the main body part 1 can be more reliable; and during separation, by lifting the main body part 1, the main body part 1 and the holder part 4 can also be carried out with the central axis of the lower circular shaft 412c as the center of rotation. The relative rotation forces the connection between the upper hook 421 and the end longitudinal connector 222 to loosen, thereby facilitating the separation of the holder 4 and the main body 1.

The following embodiments of the present invention will separately describe the structures of different components of the car body of the packback car provided by the present invention.

Care part 4

Please refer to Figures 2-11, Figure 2 is a schematic diagram of the structure of the support part, Figure 3 is an exploded view of Figure 2, Figure 4 is a partial enlarged view of the upper hook in Figure 3, Figure 5 is a front view of Figure 4, Figure 6 Fig. 3 is a partial enlarged view at A, Fig. 7 is a partial enlarged view at B in Fig. 3, Fig. 8 is a schematic structural diagram of the end wall, and Fig. 9 is a schematic structural diagram of Fig. 8 from another perspective. 10 is the connection structure diagram of the middle wall and the inclined wall, and FIG. 11 is a schematic diagram of the structure of FIG. 10 from another perspective.

As shown in Figure 2 and in conjunction with Figures 4 and 5, the clamping surface of the upper hook 421 and the end longitudinal support 222 may include a top surface section 421a and two side surface sections 421b to form a U-shaped card with the opening facing downward. Mounting surface; of the two side sections 421b, the first one can be a vertical surface, the second one can be an inclined surface inclined from top to bottom in a direction away from the first, or both side sections 421b can be from top to bottom An inclined surface with the lower edge slanted away from the other side.

In this way, the clamping surface can form a tapered clamping port that gradually shrinks from bottom to top. This type of tapered clamping port can facilitate the clamping of the upper hook 421 and the end longitudinal support 222, and the clamping effect will be improved. As the distance between the holder part 4 and the main body part 1 increases, a connection characteristic of tighter and tighter can be formed; moreover, since the lower opening of the tapered mounting port is larger, once the upper hook 421 and the end longitudinal support 222 The connection between the two is loosened, and the separation of the two can be easier.

It should be noted that the above-mentioned tapered bayonet port solution is only a preferred solution of the embodiment of the present invention, and cannot be used as a limitation on the scope of implementation of the car body of the piggyback vehicle provided by the present invention. In the specific implementation, two The side sections 421b can also be arranged as vertical surfaces, which can also meet the technical effect of snap-fitting with the main body.

During the process of installing and separating the holder 4 and the main body, there will be frictional forces in the form of sliding friction and static friction between the clamping surface of the upper hook 421 and the main body, which may cause wear and tear on the upper hook 421. Therefore, the holder wear plates 421c can be provided on the two side sections 421b to replace the direct wear of the upper hook 421 by the wear of the holder wear plates 421c, which has a positive effect on improving the service life of the holder 4.

Under long-term use conditions, this shearing force will seriously affect the reliable connection of the wear plate 421c of the support part. sex. In fact, even if the holder wear plate 421c is fixed by welding, the welding seam will receive the above-mentioned shearing force.

In view of this, in the embodiment of the present invention, a shear stop structure may be provided between the holder wear plate 421c and the side section 421b, so that the shear stop structure can offset the friction force of the holder wear plate 421c. , Each connecting piece (or welding seam) can basically be in a state of no force in the vertical direction, and the reliability of the connection can be higher.

In detail, the anti-shear stop structure can be provided on the holder wear plate 421c, such as the holder wear plate 421c on the left side in FIG. The transverse portion can resist the side section 421b, so that the friction force acting on the wear plate 421c of the support portion can act on the upper hook 421 through the transverse portion, thereby eliminating the above-mentioned shearing force; or, the anti-shearing stop structure is also It can be arranged on the side section 421b, such as the side section 421b on the right side in FIG. Furthermore, the friction force borne by the holder wear plate 421c can be offset by the force with the top wall, so as to finally eliminate the shearing force.

With reference to FIG. 3, the support portion 4 may include a bottom wall 41 and two side walls 42 connected to the bottom wall 41, and upper hooks 421 may be provided at both longitudinal ends of the two side walls 42.

For example, the limit guide of the main body 1 may be provided with a limit guide groove, from bottom to top, the limit guide groove may include a groove section of equal width and a groove section of variable width, where the width refers to the horizontal dimension, and the width is equal The width of the groove section can be roughly the same as that of the guide limiter 422, and the width of the widened groove section can gradually increase from bottom to top. In this way, the guide limiter 422 and the widened groove section can cooperate with each other to match the support part. The installation of 4 is guided to ensure the accuracy of the mounting position of the bracket 4, and when the guide limiting member 422 is inserted into the equal width groove section, the cooperation of the guide limiting member 422 and the equal width groove section can perform the support 4 Horizontal limit.

The outer side of the side wall 42 may also be provided with a reinforcing structure 423 to improve the strength of the side wall 42. The reinforcing structure 423 may be a reinforcing member in the form of a stiffener, a reinforcing plate, etc. When the body of the vehicle body is used to transport containers, the reinforced structure 423 can be an installation position for the container lock. In this way, a separate reinforced structure 423 can be omitted, which is beneficial to simplify the structure of the side wall 42.

With reference to Figures 6 and 7, in an exemplary solution, to set the installation position of the container lock, the upper cover plate of the side wall 42 can be modified first, and the outer side of the upper cover plate can be provided with a notch groove 423e corresponding to the notch groove 423e The position of the inner plate 423d and the outer plate 423c, and the neutral plate 423a and the end plate 423b connecting the inner plate 423d and the outer plate 423c can be arranged on the inner and outer sides respectively. This form of installation position has a strengthening effect on the side wall 42 Obviously, it can replace traditional reinforcing ribs, reinforcing plates and other forms of reinforcing parts.

It can be understood that the above description of the specific structure of the container lock installation position is only an exemplary description of the installation position of a specific container lock, which does not represent the installation position of all forms of container locks. In the specific implementation, if The structure of the required container lock is changed, and the structure of the above installation position can be adjusted adaptively. This point can be referred to the prior art, which will not be described in detail here.

The bottom wall 41 may include a middle wall 411 and end walls 412 located on both longitudinal sides of the middle wall 411. As shown in Figures 8 and 9, the end wall 412 can include a main body portion 412a and a connecting portion 412b, wherein the connecting portion 412b can be used to connect the main body portion 412a and the side wall 42; during the loading and unloading process, due to road vehicles To continuously drive up and down, the wheels of road vehicles must frequently crush the main body portion 412a. In order to improve the strength and service life of the main body portion 412a, the main body portion 412a can adopt a box-type structure. This aspect can ensure the strength, and the other In this way, the weight can be reduced; the lower round shaft 412c can be installed at the end of the main body 412a away from the central wall 411.

It is possible to ensure that the tires of the road vehicle roll on the main body portion 412a.

The lateral sides of the main body portion 412a may also be provided with pressing plates 412d. When the holder 4 is dropped and installed on the main body, the pressing plates 412d may exist as a driving part to drive the brake pipe guard (not shown in the figure) to rotate. return.

As shown in FIGS. 10 and 11, the middle wall 411 may include two longitudinal beams 411a arranged at intervals along the transverse direction, and the two longitudinal beams 411a may be connected by a plurality of transverse beams 411b arranged at intervals along the longitudinal direction. Since the weight of road vehicles is mainly transmitted by the wheels on both sides in the lateral direction, the middle wall 411 with the above structure can bear the gravity transmitted by the wheels on both sides in the lateral direction through two longitudinal beams 411a spaced apart in the lateral direction. The part of the transverse middle area that does not need to be in direct contact with the wheel can adopt a hollow structure composed of several spaced transverse beams 411b, which has a positive effect on reducing the weight of the middle wall 411.

Of course, the central wall 411 can also be an integrated wall, which does not affect its bearing function for road vehicles.

Each longitudinal beam 411a may include a flat beam section 411a-1 and a grid beam section 411a-2, and the flat beam section 411a-1 may include a flat plate 411a-1a and a number of reinforcing beams 411a-1b installed at the bottom of the flat plate 411a-1a The structural forms of the reinforcing beams 411a-1b can be varied, as shown in the figure, the scheme is a combination of transversely and longitudinally staggered beams. Of course, other structures can also be used, as long as the plate 411a-1a can be strengthened. The technical effect is sufficient; the grid beam section 411a-2 may include a number of small beams 411a-2a arranged at intervals along the longitudinal direction. Two small beams 411a-2a adjacent in the longitudinal direction can be connected by connecting plates 411a-2b. .

With this design, there is a gap between the two adjacent small beams 411a-2a of the grid beam section 411a-2, which can facilitate the installation of shields to limit the wheels of road vehicles; and the flat beam section 411a-1 is also It can be used as the parking position of the outrigger of the semi-trailer, so as to cooperate with the bottom plate of the outrigger, so as to reliably support the outrigger of the semi-trailer.

It should be pointed out that the embodiment of the present invention does not limit the proportion of the longitudinal beam 411a and the transverse beam 411b in the transverse direction of the central wall 411, and also does not limit the flat beam section 411a-1 and the grid beam section 411a-2 in the longitudinal beam. The proportion of 411a in the longitudinal direction can be set by those skilled in the art according to actual needs during specific implementation.

The middle wall 411 may also be provided with a longitudinal positioning structure. Specifically, the longitudinal positioning structure may include a longitudinal positioning block 411b-2, and may be installed on the transverse beam 411b, and the longitudinal positioning block 411b-2 may be provided with a V-shape or Positioning ports of other shapes. When the piggyback vehicle is driven to the designated station and parked, the positioning device on the ground can interact with the positioning port to accurately locate the longitudinal position of the piggyback vehicle, which is more convenient for the support part 4. Installation and separation.

The mounting and separating methods of the holder 4 and the main body mainly include rotation and translation: for the rotating solution, it is also necessary to provide the holder 4 with a rotation center inserting portion 411b-1, which is the rotation center inserting portion 411b-1 Specifically, it can be hole-shaped or slot-shaped, and its installation position can be on the transverse beam 411b. After the piggyback truck is driven to the designated station, the ground equipment can provide a rotating pin by lifting, etc., and insert it into the above-mentioned center of rotation. The connecting portion 411b-1 can then be used as the center of rotation of the holder 4; for the translation solution, a connecting mounting position 412a-1 of the translation driving member can also be provided on the bottom surface of the holder 4. The connecting mounting position 412a-1 is also It can be a hole type or a groove type. In FIG.

The bottom wall 41 may also include an inclined wall 413 gradually inclined upward from the inside to the outside. The inclined wall 413 is located on both lateral sides of the middle wall 411 and is used to connect the middle wall 411 and the side wall 42. The function of the inclined wall body 413 is similar to the aforementioned inclined plate portion 412b-3, which can be used to guide the tires of road vehicles to ensure that the tires of road vehicles stay on the two longitudinal beams 411a as much as possible; In the solution shown in the figure, the longitudinal ends of the inclined wall body 413 can be connected to the aforementioned inclined plate portion 412b-3.

Body part 1

Based on the above-mentioned form of the holder 4, the structure of the body 1 of the packback car body provided by the present invention is not actually limited, as long as it can have the aforementioned end connecting mechanism 22 to be connected to the longitudinal ends of the holder 4 The connection structure can be matched.

According to the embodiment of the present invention, the vehicle body can be divided into two forms according to the number of support parts 4 included in each vehicle body:

First, as shown in Figure 1, the number of the holder 4 can be one, and the main body 1 can include two end underframes 2. A bogie can be provided under the two end underframes 2 respectively. Both the bottom frames 2 can be provided with the aforementioned end connecting mechanism 22, and the support portion 4 can be installed between the bottom frames 2 at both ends.

Second, the number of the supporting parts 4 can be multiple, and the number of the supporting parts 4 is usually not more than two due to the limitation of the axle load. Taking two as an example, the main body 1 may include two end chassis 2 and a joint chassis 3, the joint chassis 3 may include two joint chassis sub-parts 3a, and the two joint chassis sub-parts 3a can pass through The joints are connected and located between the underframes 2 at both ends. A bogie is provided under the underframes 2 at both ends. The two joint underframe sub-parts 3a can share one bogie, and the two support parts 4 can They are installed between the adjacent end underframe 2 and the joint underframe sub-section 3a; in this way, the longitudinal length of each car body can be more fully utilized to increase the cargo capacity of the car body, which can effectively Reduce transportation costs.

For the end underframe 2, it may include the above-mentioned end connection mechanism 22. For the specific structure, refer to Figures 12-25. 13 is a structural diagram of the end chassis body and the end connecting mechanism, FIG. 14 is a side view of the structure in FIG. 13 installed on the bogie and connected to the support portion, FIG. 15 is an exploded view of FIG. 13, and FIG. 16 is FIG. 13 An enlarged view of the longitudinal support member at the middle end, Figure 17 is an enlarged view of the lateral stop member at the end in Figure 13, Figure 18 is an enlarged view of the first composition in Figure 13, and Figure 19 is an enlarged view of the second composition in Figure 13 Figure 20 is an enlarged view of the third composition in Figure 13, Figure 21 is an enlarged view of the third longitudinal beam and the fourth longitudinal beam in Figure 13, Figure 22 is the first corbel and the second corbel in Figure 13 Enlarged view, FIG. 23 is an enlarged view of an end side bearing in FIG. 13, FIG. 24 is an enlarged view of a container lock seat in FIG. 13, and FIG. 25 is an enlarged view of a group of reinforcing plates in FIG.

As shown in Figure 12, when there are multiple car bodies, two adjacent car bodies can be connected by two end underframes 2. In the figure, the two end underframes 2 are connected by couplers. In addition, a bogie is provided under each end underframe 2, that is, one end underframe 2 is correspondingly installed on a bogie.

With reference to Figure 13, the end connecting mechanism 22 is connected to the rear end of the end chassis body 21. The definitions of front and rear are mainly determined in conjunction with the perspective in the drawings. In fact, since each car body includes two For the symmetrical end chassis 2, the front and rear, left and right positional relationships of the two end chassis 2 are actually opposite. This can be understood in conjunction with the front, rear, left, and right labels in FIG. 12.

The end connecting mechanism 22 includes an end connecting hook 221. The hook opening of the end connecting hook 221 faces upward, and the inner hook surface of the end connecting hook 221 is provided with an end groove 221a extending in the transverse direction.

As shown in Figure 14, in the connected state, the lower round shaft 412c of the holder 4 is placed in the end groove 221a, and receives the upward supporting force from the inner surface of the end groove 221a, so that the vertical direction is effectively supported. At the same time, the inner surface of the end groove 221a can also play a certain longitudinal limit on the lower round shaft 412c. Therefore, the end underframe 2 and the supporting portion 4 have better connection reliability. Moreover, by applying an upward lifting force to the holder 4, the lower round shaft 412c can be released from the end groove 221a, which facilitates the separation of the end chassis 2 and the holder 4.

Further, as shown in FIG. 13, the end connecting mechanism 22 further includes an end longitudinal support 222, the end longitudinal support 222 is located above the end connecting hook 221, and can be directly above or diagonally above.

As shown in FIG. 16, the end longitudinal support 222 includes an end longitudinal support body 222a and end wear plates 222b fixed to the front and rear ends of the end longitudinal support body 222a.

As shown in FIG. 2, the end of the holder 4 is provided with an upper hook 421, and the hook opening of the upper hook 421 faces downward.

As shown in Figure 14, in the connected state, the end longitudinal support body 222a extends into the hook opening of the upper hook 421, and the two are hooked together. At the same time, the front end wear plate 222b and the inner hook front side of the upper hook 421 When abutting, the end wear plate 222b at the rear end abuts against the rear side of the inner hook surface of the upper hook 421, thereby supporting the supporting portion 4 in the longitudinal direction. In this way, the reliability of the connection between the end chassis 2 and the support portion 4 can be further improved, and the separation convenience of the end chassis 2 and the support portion 4 will not be affected.

As shown in FIG. 16, the upper part of the end wear plate 222b at the front end is inclined backward relative to the lower part, and the upper part of the end wear plate 222b at the rear end is inclined forward relative to the lower part.

Specifically, when connecting the bracket 4 and the end chassis 2, the above-mentioned end guide surface can guide the lower round shaft 412c to gradually slide into the end connecting hook 221 to guide the installation of the bracket 4, and When the holder 4 keeps falling, the degree of clamping between the end longitudinal support body 222a and the upper hook 421 can be gradually increased, so that the upper hook 421 can hook the end longitudinal support body 222a firmly; separating the holder 4 from the end When lifting the bottom frame 2, an upward lifting force (force F in Figure 14) can be applied to the end bottom frame 2 near the rear end. When it is lifted to a certain height, the end bottom frame 2 is in the end groove 221a. Under the guidance of the surface, the central axis of the lower circular shaft 412c is rotated counterclockwise, so that the end longitudinal support body 222a and the upper hook 421 can be released, thereby facilitating the end chassis 2 and the support 4 Separation. In short, this arrangement can improve the connection reliability and separation convenience of the end chassis 2 and the support portion 4.

In the solution shown in the figure, the top of the end longitudinal support body 222a is a trapezoidal structure with a small upper part and a larger lower part (see FIG. 16), and the height position of the end wear plate 222b at the rear end is lower than the height position of the end wear plate 222b at the front end. In this way, it can be ensured that the end chassis 2 can smoothly rotate counterclockwise as above without interference. Of course, the structure for avoiding interference is not limited to this, and can be adjusted reasonably in actual implementation. In FIG. 16, the end wear plate 222b and the end longitudinal support body 222a are connected by bolts and nuts. The end longitudinal support body 222a has a hollow structure and has an oblong hole at the bottom, which facilitates the replacement of the end wear plate 222b.

In the solution shown in the figure, the end groove 221a is a cylindrical groove (see FIG. 13), so that the inner surface of the groove 221a can play the above-mentioned guiding role when matched with the lower cylindrical shaft 412c. Of course, in actual implementation, the end The part groove 221a is not limited to a cylindrical groove.

Further, as shown in FIG. 13, the end connecting mechanism 22 further includes an end transverse limiting member 223, and the end transverse limiting member 223 is the guide limiting member provided on the end chassis 2 and the support portion 4. The positioning member 422 is matched with the positioning guide, the end transverse positioning member 223 is located above the end connecting hook 221, specifically it may be directly above or diagonally above, and the end transverse positioning member 223 is located at the end The front of the longitudinal support 222 may be directly in front or obliquely in front.

As shown in FIG. 17, the end lateral limiting member 223 includes an end lateral limiting groove 223a.

With reference to Figure 14, in the connected state, the guide limiter 422 is inserted into the end transverse limit groove 223a, and the left and right groove walls of the end transverse limit groove 223a are respectively located on the left and right sides of the guide limiter 422 Side to define the lateral position of the guide limiter 422. In this way, the reliability of the connection between the end chassis 2 and the holder 4 can be further improved.

In the solution shown in the figure, the upper part of the left side groove wall and/or the upper part of the right side groove wall of the end lateral limiting groove 223a may respectively form a left guiding surface 223b and a right guiding surface 223c (see FIG. 17), and the left guiding surface The upper side of 223b is inclined to the left relative to the lower side, and the upper side of the right guiding surface 223c is inclined to the right relative to the lower side, so that the guiding limiting member 422 can be guided into the end lateral limiting groove 223a.

The structure of the joint underframe 3 is similar to the end underframe 2, especially at the end connecting mechanism 22. For details, refer to Figure 26 for the structure of the joint underframe, and Figure 27 for the mounting on the bogie in Figure 26. Figure 28 is a structural view of one joint chassis subsection in Figure 26, Figure 29 is another perspective view of Figure 28, and Figure 30 is another joint chassis subsection in Figure 26 Fig. 31 is an exploded view of Fig. 28, Fig. 32 is an enlarged view of the joint longitudinal support in Fig. 31, Fig. 33 is an enlarged view of the joint lateral limiter in Fig. 31, and Fig. 34 is the first component in Fig. 31 Figure 35 is an enlarged view of the second joint beam and the third joint beam in Figure 31, Figure 36 is an enlarged view of a joint side bearing in Figure 31, and Figure 37 is a set of reinforcement plates in Figure 31 Zoom in.

As shown in Figure 26, the joint chassis sub-part 3a includes a joint chassis body 31, a joint connecting mechanism 32 and a joint 33. The joint connecting mechanism 32 is the end connecting mechanism 3 installed on the joint chassis 3, which is fixed on the joint The rear end of the base body 31 and the joint 33 are fixed to the front end of the joint base body 31. It should be noted that the ends of the two joint chassis sub-parts 3a that are close to each other are the front ends of the two, and the ends that are far away from each other are the rear ends of the two. In application, the joints 33 of the two joint chassis sub-parts 3a are connected by joint bearings. In the connected state, the two joint chassis sub-parts 3a can rotate in the lateral and vertical directions to adapt to the flexibility of the vehicle when turning and walking on slopes. need.

As shown in Figure 27, in application, each joint chassis sub-part 3a is connected to a support part 4, so that two adjacent support parts 4 are connected by the joint chassis 3, and two joint chassis sub-parts 3a are provided below One bogie, that is, two joint chassis sub-parts 3a (one joint chassis 3) are correspondingly installed on one bogie.

As shown in Figure 28 and Figure 30, the structures of the joints 33 of the two joint chassis subsections 3a are different. The joint 33 of one joint chassis subsection 3a is configured as a concave joint, and the joint of the other joint chassis subsection 3a is configured as a concave joint. It is a convex joint. In the connected state, the convex joint extends into the concave joint to realize a rotatably connected.

The structure of the joint connection mechanism 32 of the two joint chassis sub-parts 3a is the same, and the structure of the joint chassis body 31 is also the same. In the connected state, the joint connection structure 32 of the two joint chassis parts 3a is relatively laterally symmetrical. It is also relatively laterally symmetric. The specific structure of the joint connection mechanism 32 will be described below first, and then the specific structure of the joint chassis body 31 will be described.

As shown in FIG. 28, the joint connection mechanism 32 includes a joint connection hook 321. The hook opening of the joint hook 321 faces upward, and the inner hook surface of the joint hook 321 is provided with a joint groove 321 a extending in the transverse direction.

As shown in Figure 27, in the connected state, the lower round shaft 412c of the holder 4 is placed in the joint groove 321a, and receives the upward supporting force from the inner surface of the joint groove 321a, so that the vertical direction is effectively supported, and at the same time, The inner surface of the joint groove 321a can also play a certain longitudinal limit on the lower round shaft 412c. Therefore, the joint base frame 3 and the support portion 4 have better connection reliability. Moreover, by applying an upward lifting force to the holder 4, the lower round shaft 412c can be released from the joint groove 321a, which facilitates the separation of the joint chassis 3 and the holder 4.

Further, as shown in FIG. 28, the joint connection mechanism 32 further includes a joint longitudinal support 322, which is located above the joint connection hook 321, and may be directly above or diagonally above.

As shown in FIG. 32, the joint longitudinal support 322 includes a joint longitudinal support body 322a and a joint wear plate 322b fixed to the front and rear ends of the joint longitudinal support body 322a.

As shown in FIG. 2, the upper side of the end of the holder 4 is provided with an upper hook 421, and the hook opening of the upper hook 421 faces downward.

As shown in Figure 27, in the connected state, the end longitudinal support body 322a extends into the hook opening of the upper hook 421, and the two are hooked together. At the same time, the joint wear plate 322b at the front end abuts the front side of the inner hook of the upper hook 421. Then, the joint wear plate 322b at the rear end abuts against the rear side of the inner hook surface of the upper hook 421, thereby supporting the support portion 4 in the longitudinal direction. In this way, the reliability of the connection between the joint base frame 3 and the support portion 4 can be further improved, and the separation convenience of the joint base frame 3 and the support portion 4 will not be affected.

As shown in FIG. 32, the upper part of the joint wear plate 322b at the front end is inclined backward relative to the lower part, and the upper part of the joint wear plate 322b at the rear end is inclined forward relative to the lower part. At the same time, the inner surface of the joint groove 321a forms a joint guide surface, which when matched with the lower circular shaft 412c, can guide the drop of the holder 4 during installation, and the joint guide surface can also interact with the lower part. The round shaft 412c cooperates to guide the rotation and separation of the support portion 4 and the joint chassis 3.

Specifically, when connecting the holder 4 and the joint chassis 3, the joint guide surface can guide the lower circular shaft 412c to gradually slide into the joint connecting hook 321 to guide the installation of the holder 4, and the joint guide surface 4 When falling continuously, the degree of clamping between the joint longitudinal support body 322a and the upper hook 421 can be gradually increased, so that the upper hook 421 can hook firmly to the joint longitudinal support body 322a; when the bracket 4 and the joint chassis 3 are separated, An upward lifting force (force F in Figure 27) can be applied to the position of the joint chassis 3 near the rear end. When it is lifted to a certain height, the joint chassis 3 is guided by the inner surface of the joint groove 321a to the lower part. The central axis of the circular shaft 412c is the center of rotation to rotate, so that the joint longitudinal support body 322a and the upper hook 421 can be unlocked, thereby facilitating the separation of the joint base frame 3 and the support portion 4. In short, such an arrangement can improve the connection reliability and separation convenience of the joint chassis 3 and the support part 4.

In the solution shown in the figure, the top of the joint longitudinal support body 322a is a trapezoidal structure with a small upper part and a larger lower part (see FIG. 32). The height position of the joint wear plate 322b at the rear end is lower than the height position of the joint wear plate 322b at the front end. It is ensured that the joint chassis sub-part 3a can smoothly produce the above-mentioned lateral rotation without interference. Of course, the structure for avoiding interference is not limited to this, and can be adjusted reasonably in actual implementation. In FIG. 32, the joint wear plate 322b and the joint longitudinal support body 322a are connected by bolts and nuts. The joint longitudinal support body 322a has a hollow structure and has an oblong hole at the bottom, which facilitates the replacement of the joint wear plate 322b.

In the solution shown in the figure, the joint groove 321a is a cylindrical groove (see FIG. 28), so that the inner surface of the joint groove 321a can play the above-mentioned guiding role when matched with the cylindrical lower shaft 412c. Of course, in actual implementation, the joint groove The groove 321a is not limited to a cylindrical groove.

Further, as shown in FIG. 28, the joint connection mechanism 32 further includes a joint lateral limiter 323, which is a guide limiter 422 disposed on the joint chassis 3 and opposite to the support portion 4. Cooperating with the limiting guide, the joint lateral limiting member 323 is located above the joint connecting hook 321, which can be directly above or obliquely above, and the joint lateral limiting member 323 is located in front of the joint longitudinal support 322, specifically It can be straight ahead or diagonally forward.

As shown in FIG. 33, the joint lateral limiting member 323 includes a joint lateral limiting groove 323a.

As shown in Figure 27, in the connected state, the guide limiter 422 is inserted into the joint transverse limit groove 323a, and the left and right groove walls of the joint transverse limit groove 323a are located on the left and right sides of the guide limiter 422, respectively. Side to define the lateral position of the guide limiter 422. In this way, the reliability of the connection between the joint chassis 3 and the support portion 4 can be further improved.

In the solution shown in the figure, the upper part of the left side groove wall and/or the upper part of the right side groove wall of the joint lateral limiting groove 323a respectively form a left guiding surface 323b and a right guiding surface 323c (see FIG. 33), and the left guiding surface 323b The upper side is inclined to the left relative to the lower side, and the upper side of the right guiding surface 323c is inclined to the right relative to the lower side, so that the guiding limiting member 422 can be guided into the joint lateral limiting groove 323a.

In FIG. 33, the joint lateral limiting member 323 is composed of a U-shaped plate and two rib plates. In actual implementation, the structure of the joint lateral limiting member 323 is not limited to this.

After unlocking, the holder 4 can be separated from the joint chassis 3.

Since the installation structure of the locking mechanism on the end chassis 2 and the joint chassis 3 is similar, the following descriptions of the specific structure of the locking mechanism will take the installation on the end chassis 2 as an example. For the locking mechanism 5, the embodiment of the present invention provides the locking mechanism 5 with two structures.

The first locking mechanism 5 can refer to Figures 38-44. Figure 38 is a structural diagram of the first locking mechanism installed on the end connecting hook, and Figure 39 is the end connecting hook, the holder and the first locking mechanism Fig. 40 is a side view of Fig. 39 in a locked state, Fig. 41 is a side view of Fig. 39 in an unlocked state, and Fig. 42 is a connection structure diagram of the first lock body and the first locking driving beam assembly, Fig. 43 is an exploded view of Fig. 42, and Fig. 44 is a structural view of the first restricting portion, the second restricting portion, and the first guide sleeve fixed to the end connecting hook.

As shown in Figures 38-44, the locking mechanism 5 includes: a first lock body 51, the first lock body 51 is hinged with an end connecting hook 221 through a third hinge shaft 52, one end of the first lock body 51 is for locking The end 511, the other end is the first limiting end 512, the third hinge shaft 52 is located between the locking end 511 and the first limiting end 512; the first limiting portion 53, the first limiting portion 53 Fixed in the end receiving cavity 221b-2 (see Figure 44);

The first locking driving beam assembly 54 is connected to the first lock body 51;

In the locked state, as shown in FIG. 40, the first limiting end 512 abuts against the first limiting portion 53 from top to bottom, and the locking end 511 abuts against the holder 4 to lock the holder 4; in the unlocked state, As shown in FIG. 41, the first locking driving beam assembly 54 can drive the first limiting end portion 512 to disengage from the first limiting portion 53 from bottom to top, and the locking end portion 511 to rotate away from the supporting portion 4.

With this structure, as shown in Figures 40 and 41, during locking, if there is a tendency to separate between the holder 4 and the end connecting hook 221, the holder 4 will exert an upward force on the locking end 511 to drive The locking end portion 511 rotates counterclockwise, and the bottom-up support force generated by the first limiting portion 53 to the first limiting end portion 512 can block the rotation of the first lock body 51 in the counterclockwise direction, Therefore, the position of the locking end 511 can be guaranteed to remain unchanged, and the support portion 4 can be reliably locked; when unlocking, the first locking driving beam assembly 54 can drive the first limiting end 512 from bottom to top A limit part 53, the first lock body 51 can be rotated clockwise, and its rotation direction is opposite to the stop direction of the first limit part 53, the locking end 511 and the holder 4 can be separated smoothly, and the holder 4 can be realized. The smooth unlocking does not affect the separation of the holder 4 and the end connecting hook 221.

Here, the embodiment of the present invention does not limit the structure of the first limiting portion 53, which may be plate-shaped or block-shaped; similarly, the embodiment of the present invention does not limit the number of the first limiting portion 53, which It can be one, or it can include a plurality of mutually independent limiters, as long as it can achieve the above-mentioned technical effects.

In a detailed solution, as shown in FIG. 42, the first locking drive beam assembly 54 may include a first push beam 541, a first guide sleeve 542, and a transmission beam 543. The first guide sleeve 542 is fixed at the end to accommodate In the cavity 221b-2 (refer to FIG. 44), the first push beam 541 and the first guide sleeve 542 can be slidably connected, one end of the transmission beam 543 can be hinged with the first lock body 51, and the other end can be connected to the first push beam 541 articulated.

In this way, when the first push beam 541 is moved upward by the driving force, the hinged transmission beam 543 can convert the linear motion of the first push beam 541 into the rotational motion of the first lock body 51 to transmit to the first lock body 51 The unlocking driving force can realize the unlocking of the first lock body 51; and when the driving force disappears, relying on its own gravity, etc., the first push beam 541 can automatically slide down along the first guide sleeve 542 and drive the first lock body The reverse rotation of 51 can realize the automatic locking of the first lock body 51. Of course, the reverse driving force can also be provided by an external device to drive the first push beam 541 to reset and lock.

Specifically, the first push beam 541 may directly face the first connecting hole 221d at the end (refer to FIGS. 40 and 41), so that the unlocking member can pass through the first connecting hole 221d at the end to contact the first push beam 541, thereby facing the first connecting hole 221d. A push beam 541 applies upward unlocking driving force.

It should be pointed out that the embodiment of the present invention does not limit the source of the driving force received by the first push beam 541 when unlocking. It can be manually driven. For example, unlocking components such as an unlocking lever can be provided. The unlocking part is manually operated by the staff to generate driving force on the first push beam 541; alternatively, an automatic driving scheme can also be adopted. At this time, the power source can be a motor, an air cylinder, an oil cylinder, etc., and these power sources can be installed in the vehicle. Physically, it can also be installed on the ground equipment, which can be specifically selected according to the actual situation. A transmission mechanism can also be provided between the power source and the first push beam 541 to transmit the driving force of the power source.

The beam section of the first pushing beam 541 located above the first guide sleeve 542 may also be provided with a first connecting sleeve 541a, as shown in FIG. 43, the first connecting sleeve 541a may specifically be a U-shaped plate. It can be connected with the first push beam 541 and can form a support with the first guide sleeve 542 to serve as a limiting component for the first push beam 541 to move downwards. The transmission beam 543 can be hinged on the two side plate parts of the U-shaped plate. between.

In fact, the downward movement limit of the first push beam 541 can also be realized by the cooperation of the first limit end 512 and the first limit portion 53. In this way, the above-mentioned first connecting sleeve 541a may not exist; or , The transmission beam 543 can also be used to limit the position. The transmission beam 543 and the first push beam 541 are hinged. The two are usually set at an angle in the actual working process. The transmission beam 543 can also be used as the first A push beam 541 is a limiting component that moves downward.

In the above solution, the linear motion of the first push beam 541 is converted into the rotational motion of the first lock body 51 through the transmission beam 543. In fact, in addition to this solution, other solutions can also be used, such as , A guide hole can be provided on the first lock body 51, and the first push beam 541 can be hinged in the guide hole. When the first push beam 541 is axially displaced, the hinge axis of the first push beam 541 can be in the guide hole The inside slides to naturally drive the first lock body 51 to rotate, so that the conversion from linear motion to rotary motion can also be realized.

Further, the locking mechanism 5 may further include a locking first elastic member 541b, one end of the locking first elastic member 541b can interact with the first push beam 541, and the unlocking process is to lock the first elastic member 541b. The process of increasing the amount of deformation to gather elastic force. With this arrangement, after the driving force for the first push beam 541 disappears, the elastic force of the locking first elastic member 541b can be released to cooperate with the gravity of the first push beam 541 to jointly drive the first lock body 51 reset and lock.

Specifically, the locking first elastic member 541b may be a spring, which may be sheathed and installed on the first push beam 541, and the lower end of the first push beam 541 may be provided with a first support 541c, and both ends of the spring may be It respectively interacts with the first guide sleeve 542 and the first support 541c. Among them, the first push beam 541 can act as a spring column, which is beneficial to prevent the radial movement of the spring during the expansion and contraction process, and has a positive effect on improving the stability of the structure and the reliability of the power transmission; and this structure is adopted. In the unlocked state, the first push beam 541 can move upwards, the locking first elastic member 541b can be compressed, and when the lock is restored, the first push beam 541 can move downwards, and the locking first elastic member 541b can freed.

In fact, in the locked state, the locking of the first elastic member 541b can also have a certain amount of pre-compression, that is to say, the locking of the first elastic member 541b can still provide a certain elastic force when locked, which is important for ensuring the first elasticity. The stabilization of the locked state of the first lock body 51 has a positive effect, which can avoid the automatic unlocking of the first lock body 51 when the rail vehicle passes a curve.

In order to adjust the amount of pre-compression conveniently, the first support 541c can be a nut. In this way, by changing the screwed position of the nut, the distance between the first support 541c and the first guide sleeve 542 can be adjusted, and the locked state can be adjusted. The pre-compression amount of the first elastic member 541b is locked down.

In the unlocked state, the locking first elastic member 541b can actually be in a stretched state. At this time, the installation position of the locking first elastic member 541b can be changed. Specifically, it can be set in the first connecting sleeve. Between 541a and the first guide sleeve 542, and both ends of the first connecting sleeve 541a and the first guide sleeve 542 may be fixedly connected, so as to transmit tensile force.

The first lock body 51 may be provided with an installation groove 513, and the transmission beam 543 may be hinged in the installation groove 513, so that the thickness of the locking mechanism in the axial direction of the hinge axis of the transmission beam 543 and the first lock body 51 can be Smaller, the overall structure can be more compact. In addition, the above-mentioned installation groove 513 may also be provided in the transmission beam 543, and then the first lock body 51 may be hinged to the installation groove 513 of the transmission beam 543; or, the installation groove 513 may not be provided at this time. The thickness of the assembly formed by the transmission beam 543 and the first lock body 51 in the axial direction of the hinge axis of the transmission beam 543 and the first lock body 51 will be relatively large.

Further, the locking mechanism 5 may also include a fixed second limiting portion 55, the second limiting portion 55 may be fixed in the end accommodating cavity 221b-2, and its structure can be similar to the first limiting portion 53 Similarly, no repetitive description will be made here; the first lock body 51 may also include a second limiting end 514, and in the locked state, the second limiting end 514 can interact with the second limiting end from bottom to top. 55 offset.

In this way, in the locked state, the first lock body 51 can form a three-point support solution, the force of the first lock body 51 is more balanced, and the locking of the first lock body 51 on the holder 4 is more reliable.

In detail, the first lock body 51 may include two lock arms arranged at an included angle, and the two lock arms may be roughly formed in an L shape, and the third hinge shaft 52 may be arranged at the junction of the two lock arms, that is, an L shape. The end of one locking arm away from the third hinge shaft 52 can be the locking end 511, and the end of the other locking arm away from the third hinge shaft 52 can be the first limiting end 512; two locks A small included angle (<180 degrees) and a large included angle (>180 degrees) are formed between the arms. The side where the small included angle is located is the inner end of the connection, and the side where the large included angle is located is the connection. The outer end can be used as the second limit end 514 mentioned above.

With reference to Figure 40, in the locked state, the first limiting portion 53 can generate a bottom-up supporting force on the first limiting end 512, and the second limiting portion 55 can generate a bottom-up supporting force on the second limiting end 514. The top-down supporting force, coupled with the upward pushing force generated by the holder 4 on the locking end 511, can make the force of the first lock body 51 more balanced; moreover, through the interaction of the three force points, the third The hinge shaft 52 is basically in an unstressed state, which has a positive effect on ensuring the reliability of the locking mechanism.

In addition to the installation support point formed by the first guide sleeve 542, the first limiting portion 53, and the second limiting portion 55 of the above-mentioned locking mechanism 5, the third hinge shaft 52 can also be used as an installation support point. In other words, in conjunction with Figure 43, the outer wall of the third hinge shaft 52 can be provided with a slot, and a locking mounting plate 521 can be provided in the slot (the connection between the locking mounting plate 521 and the third hinge shaft 52 can also be directly (Using welding), the locking mounting plate 521 can be connected to the end connecting hook 221 by bolts 522 and other connectors. Of course, in addition to bolt connection, the locking mounting plate 521 and the end connecting hook 221 can also be welded And other methods for fixed connection.

For the structure of the second locking mechanism 5, please refer to Figures 45-54. Figure 45 is a structural diagram of the second locking mechanism installed on the end connecting hook, and Figure 46 is the end connecting hook, the holder and the second lock The structure diagram of the closing mechanism in the locked state. Figure 47 is the structure diagram of the end connecting hook, the support portion and the second locking mechanism in the unlocked state. Figure 48 is the second guide sleeve, the fourth limiter, and the rotation The supporting body is fixed to the structure of the end connecting hook. FIG. 49 is the connecting structure diagram of the second push beam and the connecting beam unit and the second lock body. FIG. 50 is the structure diagram of the second connecting sleeve, and FIG. 51 is the adapter block. Figure 52 is a schematic structural diagram of the lock head, Figure 53 is a structural schematic diagram of the second lock body, and Figure 54 is a structural schematic diagram of the rotating support body.

When the locking mechanism 5 is locked, the holder 4 and the end connecting hook 221 can be locked in the vertical direction to ensure reliable connection between the two and driving safety. When unlocking, it does not affect the holder 4 and the end. The convenience of separation of the connecting hook 221.

As shown in Figures 45-54, the locking mechanism 5 includes: a lock head 51', which is rotatably connected to the end connecting hook 221, and the lock head 51' is provided on both sides of its rotation centerline. The locking portion 511' and the supporting portion 512'; the second lock body 52', the second lock body 52' is slidably connected to the end connecting hook 221; the second locking driving beam assembly 53', and the second lock body 52 'Transmission connection; in the locked state, the second lock body 52' supports the supporting portion 512' from bottom to top, so that the locking portion 511' presses the support portion; in the unlocked state, the second lock driving beam assembly 53' The second lock body 52' can be driven to move in a direction away from the lock head 51', and the support portion 512' can be rotated downward about the rotation center line, so that the locking portion 511' can be rotated upward and separated from the support portion.

With this structure, in conjunction with Figure 46, in the locked state, if the holder part and the end connecting hook 221 have a tendency to separate, the holder part will generate an upward force on the locking part 511' to drive the lock 51' to rotate counterclockwise, Since the bottom-up support force generated by the second lock body 52' to the support portion 512' can block the rotation of the lock head 51' in the counterclockwise direction, the position of the lock portion 511' can be kept unchanged. Then the support portion 4 can be reliably locked; in conjunction with FIG. 47, when unlocking, the second locking driving beam assembly 53' can drive the second lock body 52' to slide in a direction away from the lock head 51', and the support portion 512' It can rotate downward about the center line of rotation, and the locking part 511 ′ can rotate upward to release the locking of the holder part without affecting the separation of the holder part 4 from the end connecting hook 221.

The rotation setting of the lock head 51' may specifically be a hinged setting. At this time, a hinge shaft can be provided for the lock head 51'. The hinge shaft can be fixed to the end connecting hook 221 and located between the locking portion 511' and the supporting portion 512'. between. Alternatively, a rotating support 54' can also be provided. The rotating support 54' can be fixed to the end connecting hook 221, and a rotating shaft portion 541' can be provided thereon. The rotating shaft portion 541' has an arc cylindrical surface, and the lock head 51 may be provided with an arc-shaped notch 513' that matches the rotating shaft portion 541', where matching means that the outer diameter of the rotating shaft portion 541' is substantially the same as the inner diameter of the arc-shaped notch 513'. When assembling, the lock head 51' can be inserted into the rotating shaft portion 541' through the arc-shaped notch 513', and can be rotated with the central axis of the rotating shaft portion 541' as the rotation center line, so that the lock head 51' can also be realized Rotation settings.

When unlocking, the rotation of the lock head 51' can be realized by the offset of the center of gravity. The center of gravity of the lock head 51' can deviate from the rotation center line in the longitudinal direction and is located on the side of the support portion 512'. For details, refer to the figure 46. The arc-shaped notch 513' can be set on the right side of the center of gravity of the lock 51'. In this way, when the second lock body 52' is displaced to the left, the lock 51' can naturally rotate counterclockwise to relieve the support part. Of the lock.

And/or, it is also possible to provide a third elastic member in the form of a spring or the like for the lock 51'. In the locked state, the third elastic member can gather elastic force in the form of tensile force/compression force, etc., when the second lock body When 52' gradually moves away, the elastic force of the third elastic member can be released to drive the lock head 51' to automatically rotate and unlock. In comparison, both of the above two methods can realize the automatic rotation of the lock head 51' when unlocking. During specific implementation, those skilled in the art can make a selection according to actual needs.

With reference to Fig. 48, in the specific assembly, the number of the rotating support bodies 54' can be two. In this way, the lock head 51' can be erected on the two rotating support bodies 54', and the installation stability of the lock head 51' is higher. In addition, the space between the two rotating support bodies 54' can be used to insert the second lock body 52', and the connection structure of the lock head 51', the second lock body 52' and the rotating support body 54' can also be more compact.

As shown in FIG. 54 again, the rotating support 54' may further include a third limiting portion 542', which may be angular or the like. In the unlocked state, the third limiting portion 542' may be connected to The support portion 512' resists to limit the downward rotation of the support portion 512'. At the same time, it can also support the gap where the second lock body 52' is inserted from below the support portion 512' to facilitate the second lock body 52' Is inserted again to support the supporting portion 512'.

Here, the embodiment of the present invention does not limit the support height of the third limiting portion 542'. During specific implementation, those skilled in the art can set it according to actual needs, as long as the third limiting portion 542' and the supporting portion 512' are guaranteed When supporting, the locking portion 511' can unlock the support portion while leaving an insertion gap for the second lock body 52'.

Furthermore, as shown in FIG. 52, a supporting groove 514' may be further provided on the lock 51'. When unlocking, the aforementioned third limiting portion 542' may be inserted into the supporting groove 514'. It can be understood that the depth at which the third limiting portion 542' is inserted into the supporting groove 514' actually determines the supporting height of the supporting portion 512' when unlocked. Therefore, in specific practice, the depth of the supporting groove 514' can also be adjusted. Adjust the supporting height of the supporting portion 512'.

With reference to Figure 53, the second lock body 52' may include an insertion section 521' with an inclined guide surface. When locking, the insertion section 521' can be inserted from below the supporting portion 512' and can be supported by the inclined guide surface The supporting portion 512' is supported by each other to gradually drive the supporting portion 512' to rotate upward, the locking portion 511' to rotate downward, and to lock the supporting portion.

The second lock body 52' may only include the insertion section 521'. Under this condition, when in the locked state, the second lock body 52' can still be supported by the inclined guide surface and the supporting portion 512', and when in the unlocked state, The second lock body 52' can be completely disengaged from the support portion 512', or the inclined guide surface can be supported by the support portion 512', that is, when unlocking, the second lock body 52' and the lock head 51' need not be Completely disengaged, at this time, the second lock body 52' itself can also limit the rotation of the lock head 51', and since the lock head 51' is still on the second lock body 52', there is no second lock body 52' For the problem of inability to insert, the aforementioned third limiting portion 542' may not exist.

In the scheme of the drawings, still referring to Figure 53, the second lock body 52' may include a three-part structure, which is a large-size support section 523' with a larger vertical size and an insertion section 521 with a vertical variable size. ′ And the small supporting section 524′ with a smaller vertical dimension, the large supporting section 523′ has a first supporting plane, and the small supporting section 524′ has a second supporting plane. In the locked state, the second lock body 52′ It can be supported by the first support plane and the support portion 512', and in the unlocked state, the second lock body 52' can be supported by the second support plane and the support portion 512'.

Since the surface supported by the support portion 512' is a flat surface, the lock head 51' can be more stable during unlocking and locking; and based on the above design, the support portion 512' and the second lock body 52' are parallel to each other during unlocking. If it is not completely separated, the small-sized supporting section 524' will naturally form a rotation limit of the supporting portion 512', and the aforementioned third limit portion 542' may not exist.

As a modification of the solution shown in FIG. 53, the second lock body 52' may also only include a large-size support section 523' (or a small-size support section 524') and an insertion section 521', which can also achieve the second lock body 52' Function.

A guiding structure may be provided between the second lock body 52' and the rotating support body 54' to guide the sliding direction of the second lock body 52'.

Specifically, in the second lock body 52' and the rotating support body 54', one can be provided with a sliding groove 522', and the other can be provided with a sliding part matching the sliding groove 522', and the sliding part can be inserted It is connected to the sliding groove 522' and can slide along the sliding groove 522'. The sliding portion may be an integral structure, such as the elongated sliding rail 543' shown in the drawings, or may also be a split structure, for example, may include a number of sliding blocks arranged at intervals.

Further, it may also include a fixed fourth limiting portion 55'. The fourth limiting portion 55' can be fixed in the end accommodating cavity 221b-2. In the locked state, the fourth limiting portion 55' can freely The top and bottom are pressed against the supporting portion 512'.

In this way, in the locked state, the lock head 51' can form a three-point support solution, the force of the lock head 51' is more balanced, and the lock head 51' can be more reliable for the locking of the holder; moreover, due to the three receiving With the interaction of the force points, there is basically no force action between the arc-shaped notch 513' and the rotating shaft portion 541', which has a positive effect on ensuring the reliability of the locking mechanism.

Here, the embodiment of the present invention does not limit the structure of the fourth limiting portion 55', which may be plate-shaped or block-shaped; similarly, the embodiment of the present invention does not limit the number of the fourth limiting portion 55' either It can be one or multiple independent limiters, as long as it can achieve the above-mentioned technical effects.

Please refer to FIG. 49 in combination with FIGS. 46 and 47. In an exemplary solution, the second locking driving beam assembly 53' may include a second pushing beam 531', a second guide sleeve 532', and a connecting beam unit 533', the second guide sleeve 532' can be fixedly arranged, specifically, it can be installed in the end accommodating cavity 221b-2 (refer to Figure 48), and the second push beam 531' can be slidably connected to the second guide sleeve 532' One end of the connecting beam unit 533' is hinged with the second push beam 531', and the other end is hinged with the second lock body 52'.

With this structure, when the second push beam 531' is moved upward by the driving force, the hinged connecting beam unit 533' can drive the second lock body 52' to slide in a direction away from the lock head 51', and then the lock head 51' can be rotated and unlocked by itself; and when the driving force disappears, relying on its own gravity, etc., the second push beam 531' can automatically slide down along the second guide sleeve 532', and drive the second lock body through the connecting beam unit 533' 52' slides in the direction close to the lock head 51' to support the support portion 512' again. The lock head 51' can be rotated in reverse to realize automatic locking. Of course, it can also be driven by an external device in the reverse direction. Force to drive the second push beam 531' to reset and lock.

Specifically, the second push beam 531' may be directly opposite to the first connecting hole 221d at the end (refer to FIGS. 46 and 47), so that the unlocking member can pass through the first connecting hole 221d at the end to contact the second push beam 531', thereby An upward unlocking driving force is applied to the second push beam 531'.

It should be pointed out that the embodiment of the present invention does not limit the source of the driving force that the second push beam 531' receives when unlocking. It can be manually driven. For example, unlocking components such as an unlocking lever can be provided. When unlocking is required, The unlocking component can be manually operated by the staff to generate driving force on the second push beam 531'; alternatively, an automatic driving scheme can also be adopted. At this time, the power source can be a motor, an air cylinder, an oil cylinder, etc., and these power sources can be installed On the vehicle body, it can also be installed on the ground equipment, which can be specifically selected according to the actual situation. A transmission mechanism can also be provided between the power source and the second push beam 531' to transmit the driving force of the power source.

The beam section of the second push beam 531' located above the second guide sleeve 532' may also be provided with a second connecting sleeve 531a'. As shown in FIG. The pipe part can be installed on the upper part of the second push beam 531' through threaded connection, welding, interference fit, etc. The hinge part may include two hinged plates arranged oppositely, and the aforementioned connecting beam unit 533' may be hinged on these two Between hinged plates.

The above-mentioned second connecting sleeve 531a' and the second guide sleeve 532' can also be used as a limiter for the downward movement of the second pushing beam 531' to limit the maximum downward movement distance of the second pushing beam 531'. At the same time, The displacement distance of the second lock body 52' is also limited.

In fact, the downward movement limit of the second push beam 531' can also be realized by the cooperation of the lock head 51' and the fourth limit portion 55'. In this way, the above-mentioned second connecting sleeve 531a' may not exist; or It is also possible to use the connecting end of the connecting beam unit 533' and the second push beam 531' to limit the position. The connecting end and the second push beam 531' adopt a hinged connection scheme. It is usually arranged at an included angle. Therefore, even if the second connecting sleeve 531a' does not exist, the connecting end can also be used as a limiting component for the second push beam 531' to move downward.

Furthermore, it may further include a second elastic member 531b', one end of the second elastic member 531b' can act on the second push beam 531', and in the unlocked state, the deformation of the second elastic member 531b' can be increased, To gather elasticity. With this arrangement, after the driving force for the second push beam 531' disappears, the elastic force of the second elastic member 531b' can be released to cooperate with the gravity of the second push beam 531' to jointly drive the lock 51 'Reset and lock.

Specifically, the second elastic member 531b′ may be a spring, which may be sheathed and installed on the second push beam 531′, and the lower end of the second push beam 531′ may be provided with a second support member 531c′. The ends can respectively abut against the second guide sleeve 532' and the second support 531c'. Among them, the second push beam 531' can act as a spring column, which is beneficial to prevent the radial movement of the spring during the expansion and contraction process, and has a positive effect on improving the stability of the structure and the reliability of power transmission; and adopting this Structure, in the unlocked state, the second push beam 531' can be displaced upwards, and the second elastic member 531b' can be compressed, and when the lock is restored, the second push beam 531' can be displaced downwards, and the second elastic member 531b' Can be released again.

In fact, in the locked state, the second elastic member 531b' can also have a certain amount of pre-compression, that is, the second elastic member 531b' can still provide a certain elastic force when locked, which is useful for ensuring the lock 51 'The stability of the locked state has a positive effect, which can avoid the automatic unlocking of the lock 51' when the rail vehicle passes a curve.

In order to adjust the amount of pre-compression conveniently, the second support 531c' can be a nut. In this way, by changing the screwed position of the nut, the distance between the second support 531c' and the second guide sleeve 532' can be adjusted. Adjust the pre-compression amount of the second elastic member 531b' in the locked state.

In the unlocked state, the second elastic member 531b' can actually be in a stretched state. At this time, the installation position of the second elastic member 531b' can be changed. Specifically, it can be arranged in the second connecting sleeve 531a' It can be fixedly connected to the second guide sleeve 532', and at both ends of the second connecting sleeve 531a' and the second guide sleeve 532', so as to transmit tensile force.

The connecting beam unit 533' may be a structure formed by a combination of multiple connecting beams. In an exemplary solution, the connecting beam unit 533' may include a first locking connecting beam 533a' and a second locking connecting beam 533b. ′ And the adapter block 533c′, the adapter block 533c′ may be provided with non-collinear fixed hinge points 533c-1′, first hinge points 533c-2′ and second hinge points 533c-3′, and fixed hinge points 533c -1' can be fixed, specifically, it can be fixed to the end hook 221, one end of the first locking connecting beam 533a' can be hinged to the second push beam 531', and the other end can be hinged to the first hinge point 533c-2' One end of the second locking connecting beam 533b' can be hinged to the second lock body 52', and the other end can be hinged to the second hinge point 533c-3'.

With this structure, as shown in Figure 46 and Figure 47, when the second push beam 531' moves upward, the first locking connecting beam 533a' can be driven to move upward, and then the adapter block 533c' can be driven around the fixed hinge point. 533c-1' rotates clockwise, and the adapter block 533c' drives the second locking connecting beam 533b' and the second lock body 52' to move to the left, and the lock head 51' can rotate counterclockwise to unlock the support part; When the second push beam 531' moves downwards, the first locking connecting beam 533a' can be driven to move downwards, and then the adapter block 533c' can be driven to rotate counterclockwise, and the adapter block 533c' can drive the second The locking connecting beam 533b' and the second lock body 52' move to the right, and the lock head 51' can rotate clockwise to re-lock the holder.

It should be pointed out that the foregoing description of the specific structure of the second locking drive beam assembly 53' is only a preferred solution of the embodiment of the present invention, and cannot be regarded as the scope of implementation of the body of the piggyback vehicle provided by the present invention. Under the condition that the function is satisfied, other forms of the second locking driving beam assembly 53' can also be used. For example, the second locking driving beam assembly 53' can adopt a beam directly arranged to be capable of linear displacement.

Further, as shown in FIG. 1, the main body 1 is also provided with a lateral stop mechanism 6. When the bracket 4 is reset from the position separated from the end chassis 2 to the position connected with the end chassis 2, the lateral stop mechanism can determine the reset position of the bracket 4 to ensure the accurate installation of the bracket 4于体部1。 In the body section 1.

Specifically, the lateral stop mechanism 6 can be installed on the end base frame 2 and the joint base frame 3. Since the installation structure is similar, the following only takes the end base frame 2 as an example to describe the lateral stop mechanism 6 Structure, similarly, the embodiment of the present invention also provides the lateral stop mechanism 6 in two structural forms.

The structure of the first lateral stop mechanism 6 can be referred to Figures 55-61. Figure 55 is a structural diagram of the first lateral stop mechanism installed on the end connecting hook, and Figure 56 is a specific example of the first lateral stop mechanism. Fig. 57 is an exploded view of Fig. 56, Fig. 58 is a schematic structural diagram of the support, Fig. 59 is a split structure diagram of the first connecting beam, and Fig. 60 is another type of the first lateral stop mechanism FIG. 61 is an exploded view of the connection structure between the first stop beam and the connection end in FIG. 60.

As shown in Figures 55-57, the first type of lateral stop mechanism 6 includes: a support 61, the support 61 is fixed to the end connecting hook 221, which can be fixed by welding, etc., and the support 61 is provided with a through hole 611; first stop beam 62; stop driving beam assembly 63, drivingly connected with the first stop beam 62; in the stop state, the first stop beam 62 can extend through the hole 611, to support the part 4 A lateral stop is formed, and in the unblocked state, the stop driving beam assembly 63 can drive the first stop beam 62 to retract to release the stop on the support portion 4.

With this structure, in the stopped state, the first stop beam 62 can extend from the through hole 611 to form a lateral stop to the support portion 4, thereby ensuring the accurate reset of the support portion 4; and in the unblocked state Next, the stop driving beam assembly 63 can act on the first stop beam 62 to retract it, so that the stop on the support portion 4 can be released, so as not to affect the normal operation of the support portion 4 and the end chassis 2. Separate.

Further, a third elastic member 64 may be included. The third elastic member 64 can act on the first stop beam 62. During the unblocking process, the deformation amount of the third elastic member 64 will increase to gather the elastic force. In this way, when the driving force used to stop the driving beam assembly 63 disappears, the third elastic member 64 can be released to drive the first stop beam 62 to automatically return to the stop position, which can improve the automation degree of the equipment.

57, the first stop beam 62 may include a thick neck portion 621 and a thin neck portion 622, a step surface 623 may be formed between the two, and the third elastic member 64 may be a spring, which can be sheathed and installed on the thin neck portion 622 , And can interact with the step surface 623. At this time, the thin neck 622 can also function as a spring column to guide the expansion and contraction of the spring, which can largely avoid the radial movement of the spring during the expansion and contraction process, which is useful for improving the stability and reliability of the transmission. Has a positive effect.

It should be pointed out that in addition to the spring solution, the third elastic member 64 can also adopt other forms of elastic elements such as elastic balls, elastic blocks, tension ropes, etc., as long as the use effect can be satisfied.

The support 61 can also be provided with a stop and limit member 65, and both ends of the third elastic member 64 can respectively interact with the stop and limit member 65 and the step surface 623. In the scheme of the drawings, the first stop beam 62. The thick neck 621 can be used as a stop part to increase the strength of the stop part. When unblocking, the stepped surface 623 can generate a compressive force on the third elastic member 64 to increase the compression amount of the third elastic member 64. In this solution, the third elastic member 64 is in contact with the stop and limit member 65 and the step surface 623.

Moreover, the cross section of the thick neck portion 621 may be non-circular, and the through hole 611 can match the thick neck portion 621. The matching here means that the shapes and sizes of the two are roughly the same. Thus, when the thick neck portion 621 is inserted When in the via 611, the two will not rotate relative to each other, and the reliability of the stop positioning can be improved. Further, the stop surface of the thick neck portion 621 in contact with the support portion 4 can be a flat surface. In this way, the contact area between the support portion 4 and the stop surface can be larger, and the reliability of the stop can be improved to a greater extent. improve.

In fact, in the process of unblocking, the third elastic member 64 can also generate a tensile force. At this time, the narrow neck 622 of the first stop beam 62 can be used as a stop part for contact with the support part 4, and this In the solution, both ends of the third elastic member 64 need to be connected with the stop and limit member 65 and the step surface 623 so as to be able to generate a pulling force when unblocking.

The structure of the stop and limit member 65 is not limited here. During specific implementation, those skilled in the art can set it according to actual needs, as long as the above-mentioned effects can be achieved. For example, in the solution of FIG. 57, the stop and limit member 65 can be in the shape of a sleeve. The sleeve can be a cylinder, a square tube or a special-shaped tube of other shapes. The sleeve can protect the spring. , In order to avoid the interference of rain, dust, etc., affecting the normal operation of the spring; in the solution of FIG. 60, the stopper 65 can be plate-shaped or block-shaped. The support 61 is connected. At this time, the spring is in a relatively open space, and the operator can directly observe it to facilitate the adjustment of the installation state of the spring.

58, in fact, the embodiment of the present invention does not limit the structure of the support 61, its structure is mainly to adapt to the connection with the end connecting hook 221, in specific implementation, those skilled in the art can according to the end connection The hook 221 is used to adjust the shape of the support 61. The support 61 needs to provide corresponding mounting points. One of the mounting points is the aforementioned through hole 611. The figure also shows another mounting point-mounting hole 612. This mounting hole 612 can be used to install the brake pipe assembly of the piggyback vehicle (not shown in the figure).

The stop driving beam assembly 63 may include a first connecting beam 631 hingedly arranged. One end of the first connecting beam 631 may be a first driving end 6311 for receiving external driving force, and the other end may be a connecting end 6312. The first hinge shaft 633 of the first connecting beam 631 can be fixedly arranged. Specifically, it can be fixedly installed on the support 61 and located between the first driving end portion 6311 and the connecting end portion 6312. The connecting end portion 6312 is It can be connected to the first stop beam 62 in transmission.

Here, the embodiment of the present invention does not limit the source of the driving force that the stop driving beam assembly 63 receives when disengaging. It can adopt a manual driving scheme. When shifting, the staff can manually operate the unblocking component to generate driving force to the first driving end 6311; alternatively, an automatic driving scheme can also be adopted. In this case, the power source can be a motor, an air cylinder, an oil cylinder, etc. The power source can be installed on the car body or on the ground equipment. It can be selected according to the actual situation. A transmission mechanism can also be provided between the power source and the first drive end 6311 to transmit the driving force of the power source. .

With this arrangement, through the cooperation of the second hinge shaft 634 and the strip-shaped guide hole 631a-1, the rotational movement of the connecting end portion 6312 can be converted into the linear movement of the second connecting beam 632, thereby driving the first stop beam 62 to perform Extend or retract.

In the drawings, the above-mentioned strip-shaped guide hole 631a-1 can be provided on the connecting end 6312, and the second hinge shaft 634 can be fixed on the second connecting beam 632. In this way, the size of the second connecting beam 632 can be relatively smaller. Small, the structure can be more compact.

In specific practice, the spring may have a certain amount of pre-compression to ensure the reliability when the first stop beam 62 is at the stop position, and the above-mentioned pre-compression amount can be adjusted by the second connecting beam 632 and the first stop The connection position of the beam 62 is determined.

Based on the solution of using threaded connection between the second connecting beam 632 and the first stop beam 62 to be fixed, a first anti-loosening member 624 can also be provided, and the first anti-loosing member 624 can also be connected to the first stop beam 62. It can be tightly pressed against the second connecting beam 632 to prevent loosening and fixing of the second connecting beam 632. The first anti-loosening member 624 may specifically be an anti-loosening nut, and of course, it may also be an anti-loosing stop limiting member in the form of an insert bar, a stopper, or the like.

Further, it may also include a stop connecting plate 613 and a guard plate 614. One end of the stop connecting plate 613 can be connected to the support 61, and the other end can be connected to the guard plate 614 for protecting the stop driving beam assembly 63 The aforementioned first hinge shaft 633 can be installed on the stop connecting plate 613, and the specific installation method can be welding, or it can also be installed with the aid of the mounting plate 633a and bolts, as long as the reliable fixing of the first hinge shaft 633 can be ensured. That's it. In fact, the stop connecting plate 613 and the guard plate 614 can also be used as a part of the support 61.

In another solution, as shown in FIGS. 60 and 61, the connecting end portion 6312 may be provided with a strip-shaped guide groove 631e, the first stop beam 62 may be inserted into the strip-shaped guide groove 631e, and the connecting end portion 6312 It can be opposed to the locking member 631f provided on the first stop beam 62 to define the connection position of the connecting end 6321 and the first stop beam 62.

With this arrangement, through the cooperation of the first stop beam 62 and the strip-shaped guide groove 631e, the rotational movement of the connecting end portion 6312 can also be converted into the linear movement of the first stop beam 62 to drive the first stop beam 62 to perform Unblock or return to the stop.

In detail, the connecting end portion 6312 may be defined between the locking member 631f and the stop limiting member 65, and the pre-compression of the third elastic member 64 can be adjusted by the locking member 631f on the first stop beam 62 The installation position is determined, and a first gasket 631g may be provided between the locking member 631f and the connecting end portion 6312 to reduce the wear at the connection between the two.

The connection between the locking member 631f and the first stop beam 62 may be threaded connection, or welding, etc., when it is threaded connection, it may also include a second anti-loosening member, which may be an anti-loosening member. The nut may also be a stop insert (not marked in the drawings), a stop block, etc., to limit the installation position of the locking member 631f.

In comparison, both of the above two solutions can realize the conversion of the rotary motion of the first connecting beam 631 to the linear motion of the first stop beam 62, and can realize the switching of the first stop beam 62 between the stopped state and the unblocked state. In specific applications, those skilled in the art can make selections according to actual needs.

Taking the foregoing first solution as an example, the first connecting beam 631 may include a long plate 631a and a short plate 631b arranged at intervals, and the first hinge shaft 633 can be connected to the long plate 631a and the short plate 631b. One end of the plate 631a forms the aforementioned connecting end 6312, the aforementioned strip-shaped guide hole 631a-1 can be provided on the long plate 631a, and the other end of the long plate 631a can be connected to the short plate 631b. There is a roller 631c. At this time, the long plate 631a, the short plate 631b, and the roller 631c are combined to form the first driving end portion 6311.

When an external driving force acts on the roller 631c, the roller 631c can rotate, which can reduce the friction between the first driving end portion 6311 and the external driving device, and has a positive effect on reducing the wear of the first driving end portion 6311.

59, it may also include a roller 631d, the roller 631d may include a rod portion 631d-1 and a head portion 631d-2, the radial dimension of the head portion 631d-2 may be larger than the rod portion 631d-1, the long plate 631a, The short plate 631b may be provided with a through hole 631b-1, and the through hole 631b-1 of the inner one of the two may be a stepped hole. In the assembled state, at least part of the head 631d-2 may be hidden in In the large-diameter hole section of the stepped hole, the end of the rod portion 631d-1 away from the head portion 631d-2 can be matched and locked with the lock nut 631d-3.

The “inside” here refers to the side close to the end connecting hook 221. With this design, the protruding length of the roller 631d on the inner side can be shorter, which can largely prevent the end of the first driving end 6311 from rotating. The contact friction between the part connecting hooks 221.

In the above solutions, the restoration stop of the first stop beam 62 mainly relies on the third elastic member 64 directly acting on the first stop beam 62. In fact, in addition to this solution, it can also be stopped by The stop driving beam assembly 63 drives the first stop beam 62 to return to the stop state. That is to say, the first stop beam 62 can be unlocked and returned to the stop by the stop driving beam assembly 63. This solution This can be achieved by providing an elastic member to the stop driving beam assembly 63.

In addition, a core of the above-mentioned lateral stop mechanism is the separation of the stop driving beam assembly 63 and the first stop beam 62. In the stop state, only the first stop beam 62 and the support 61 are actually stressed for The stop driving beam assembly 63 participating in the driving is not stressed, which is a key point of higher reliability of the above-mentioned lateral stop mechanism.

Refer to Figures 62-67 for the structure of the second type of lateral stop mechanism 6. Figure 62 is a diagram of the relative position of the second type of lateral stop mechanism with the end connecting hooks and brackets in the stopping state, and Figure 63 is Figure 62 Figure 64 is the relative position diagram of the second lateral stop mechanism and the end connecting hooks and brackets in the unblocked state, Figure 65 is a partial enlarged view of Figure 64, Figure 66 is the second lateral A structural diagram of the stop mechanism installed on the end connecting hook, and FIG. 67 is an exploded view of FIG. 66.

As shown in FIGS. 63 and 65-67, the lateral stop mechanism 6 includes: a second stop beam 61' hingedly arranged, and two ends of the second stop beam 61' are driving ends 611' respectively And the stop end 612', the hinge shaft 613' of the second stop beam 61' is located between the driving end 611' and the stop end 612', and the hinge shaft 613' is fixed to the end connecting hook 221; The position beam 62' is fixed to the end connecting hook 221; in the stopping state, the limit beam 62' is pressed against the outer side of the second stop beam 61' in the transverse direction, and the second stop beam 61' can support The portion 4 forms a lateral stop; in the unblocked state, the driving end portion 611 ′ can rotate under force to drive the stop end portion 612 ′ to release the stop on the support portion 4.

With the above structure, in the stopping state, the limit beam 62' can be pressed against the second stop beam 61' in the lateral direction to provide lateral support for the second stop beam 61', and then the second stop beam 61' forms a lateral stop on the support portion 4, which can ensure the accurate reset of the support portion 4; and in the unblocked state, the driving end portion 611' can receive force and drive the entire second stop beam 61' to rotate, thereby The stop end 612 ′ can be driven to rotate to release the stop, so as not to affect the normal separation of the support portion 4 and the end chassis 2.

More importantly, in the stopping state, when the support part 4 is reset and hits the second stop beam 61', only the stop end 612' and the limit beam 62' are forced to move as a lateral stop mechanism. Part of the driving end 611' is not subject to force, which plays a key role in ensuring the reliability of the lateral stop mechanism.

It should be pointed out that the embodiment of the present invention does not limit the source of the driving force received by the driving end 611' when disengaging. It can adopt a manual driving scheme. When shifting, the staff can manually operate the unblocking components to generate driving force on the drive end 611'; alternatively, an automatic driving scheme can also be adopted. At this time, the power source can be a motor, an air cylinder, an oil cylinder, etc., these powers The source can be installed on the vehicle body or on the ground equipment, which can be selected according to the actual situation. A transmission mechanism can also be provided between the power source and the driving end 611' to transmit the driving force of the power source.

Further, it may also include a first limiting member 63', the first limiting member 63' is fixed to the end connecting hook 221, and in the unblocked state, the second stop beam 61' can be connected to the first limiting member 63 ′ To avoid excessive rotation of the second stop beam 61 ′.

Here, the embodiment of the present invention does not limit the shape of the first limiting member 63', which may be plate-shaped, block-shaped, column-shaped, etc., which can be specifically determined according to actual conditions; similarly, the embodiment of the present invention also The number and installation position of the first limiting member 63' are not limited, as long as the above-mentioned effects can be achieved. In an exemplary solution of the present invention, the first limiting member 63' may be formed by extending the end hook wall plate 221c of the end connecting hook 221, so that there is no need to specially provide the first limiting member 63. ′, the number of parts can be less.

In the disengaged state, that is, when the second stop beam 61' is against the first stopper 63', the center of gravity of the second stop beam 61' can deviate from the hinge shaft 613' in the longitudinal direction and is located at the stop end The side where the section 612' is located. In this way, when the driving force used to drive the end portion 611' disappears, under the action of the gravity of the second stop beam 61', the second stop beam 61' can automatically rotate to the stop state without the need to provide other The structure of the drive component and the device can be relatively simple.

And/or, it may further include a fourth elastic member 65' for stopping, and the fourth elastic member 65' for stopping can act on the second stopping beam 61'. During the unblocking process, the fourth elastic member 65' is stopped. The amount of deformation can be increased to gather elastic force. In this way, when the driving force used to drive the end portion 611' disappears, the elastic force collected by the stop fourth elastic member 65' can be released, alone or in cooperation with the aforementioned gravity, to jointly drive the second stop beam 61' rotates to the stop state.

The above-mentioned stop fourth elastic member 65' may specifically be a torsion spring, which can be sheathed and installed on the hinge shaft 613'. For example, the end connecting hook 221), the other extended end can abut against the second stop beam 61'. When the second stop beam 61' rotates to release the stop state, the torsion spring can gather the torsional deformation force, and When the driving force used to drive the end portion 611' disappears, the aforementioned torsional deformation force can be released to drive the second stop beam 61' to automatically rotate.

The above-mentioned stop fourth elastic member 65' may also be a linear spring, such as a tension spring, a compression spring, etc., a spring element that generates elastic force by displacement in the axial direction. Taking the solution in FIG. 65 as an example, the linear spring may be The tension spring, one end of the tension spring can be fixed, and the other end can be connected to the second stop beam 61', so that the elastic force can be gathered when the second stop beam 61' rotates to release the stop.

In addition to the above-mentioned torsion spring and linear spring, the stop fourth elastic member 65' may also be an elastic element in the form of an elastic block, an elastic ball, a tension rope, etc., as long as the above-mentioned technical effects can be achieved.

Furthermore, it may also include a second limiting member 64', the second limiting member 64' is fixed to the end connecting hook 221, and in the stopping state, the second stopping beam 61' can be connected to the second limiting member 64' is opposed to limit the position of the second stop beam 61' in the stop state. The structure, quantity, and installation position of the second limiting member 64' can be similar to those of the first limiting member 63', and no repeated description will be made here.

Moreover, with the support of the above-mentioned second stopper 64', the second stop beam 61' can be arranged with a gap between the stop beam 62' in the vertical direction, so that the stop beam 62' does not need to bear the second stop beam 61' Correspondingly, no shear stress will be generated at the connection between the limit beam 62' and the end connecting hook 221, and the connection reliability of the limit beam 62' and the end connecting hook 221 can be higher.

Regarding the lateral stop mechanism 6 of the holder 4 involved in the above embodiments, the following embodiments of the present invention will also describe the structure of the second stop beam 61'.

With reference to Figure 63, in the stopping state, the driving end 611' may be an end gradually inclined from top to bottom toward the stopping end 612', so that when the driving end 611' receives an upward driving force, The second stop beam 61' will naturally rotate in the direction of releasing the stop state to ensure that the second stop beam 61' can be unlocked smoothly.

It can be understood that adjusting the shape of the driving end portion 611' is actually adjusting the driving force and the direction of action of the driving end portion 611'. In this way, in specific implementation, the second stop beam can also be realized by adjusting the direction of the driving force. The 61' rotation is unlocked.

In addition, in the stopping state, the end of the second stop beam 61 ′ far away from the driving end 611 ′ may be provided with a downward bending elbow, and this elbow may serve as the above-mentioned stopping end 612 ′. The arrangement of the head can increase the strength of the stop end 612', and at the same time, can also avoid the vehicle body and the brake pipe guard (not shown in the figure).

67, the hinge shaft 613' of the second stop beam 61' may be a stepped shaft, which may specifically include a large-diameter section 613a′ and a small-diameter section 613b′, wherein the large-diameter section 613a′ can be used to connect the hook with the end 221 is connected, the second stop beam 61' can be installed on the large-diameter section 613a'; it can also include a third limiting member 613c', which can be specifically a nut, which can be installed on the small-diameter section 613b' , In order to cooperate with the end connecting hook 221 to define the installation position of the second stop beam 61'. It should be understood that the function of the third limiting member 613c' is mainly for limiting, not for locking. After the installation is completed, it is necessary to ensure that the second stopping beam 61' can rotate smoothly.

A second gasket 613d′ may also be provided between the third limiting member 613c′ and the second stop beam 61′. The second gasket 613d′ may be made of rubber or metal, etc., which can avoid the The direct friction between the second stop beam 61' and the third limit member 613c' has a positive effect on reducing wear.

Brake pipe guard 10

The brake pipe is an important part of the railway vehicle. It needs to penetrate the car body in the longitudinal direction during installation. For the piggyback car, due to the repeated separation and installation of the support part 4 and the body part 1, the brake pipe has It may interfere with the separation and installation of the holder part. Once interference occurs, the brake tube may be damaged by the holder part 4 during operation.

To this end, the present application also relates to a flip-type brake tube protection device, which includes a protection shell and a brake tube installed on the protection shell. , The protective shell can be turned outward in the vertical plane along the lateral direction to avoid interference with the support part 4, and when the support part 4 is dropped to be installed on the body part 1, the protective shell can be turned inward in the transverse direction to return to the original In this way, it is possible to better prevent the brake tube from interfering with the supporting part 4 in action. At the same time, the protective shell can also protect the brake tube, which can prevent the brake tube from contacting the ground and causing abrasion and leakage. The driving safety of the back car has a positive effect.

Specifically, please refer to Figures 68-81, Figure 68 is a structural diagram of the brake pipe protection device, Figure 69 is an enlarged view at C in Figure 68, Figure 70 is an enlarged view at D in Figure 68, and Figure 71 is Fig. 68 is an enlarged view at E, Fig. 72 is a structural view of the brake tube protection device in the connection state of the support part and the body part, Fig. 73 is an enlarged view of the inner part of the circle in Fig. 72, and Fig. 74 is a brake tube protection The structure of the device in the separated state of the holder and the main body. Figure 75 is an enlarged view of the inner part of the circle in Figure 74, and Figure 76 is a structural view of the first and second protective limiters arranged on the support , Figure 77 is a structural diagram of the first pivot plate, Figure 78 is a structural diagram of the second pivot plate, Figure 79 is a structural diagram of the protective partition, Figure 80 is a structural diagram of the pipe hanger plate, Figure 81 is a pipe Hanging connecting plate structure diagram.

As shown in FIG. 72, the body of a packback car usually includes a body portion 1 and a support portion 4, and the support portion 4 can be separated from the body portion 1 by rotating the support portion 4 in a vertical direction or translating the support portion 4 in a horizontal direction. The brake tube is arranged on the laterally outer side of the support part 4, and when the support part 4 is rotated around the vertical direction or the support part 4 is translated horizontally, in order to avoid the interference of the brake tube, the support part 44 needs to be lifted upward for a certain distance. In order to shorten the lifting distance and protect the brake pipe, the present invention designs a brake pipe protection device.

As shown in FIG. 68, the brake pipe protection device 10 includes a protection housing 11, and the housing cavity of the protection housing 11 is used for accommodating the brake pipe. The protective housing 11 can protect the brake pipe on the one hand, and facilitate the unified movement of the brake pipe on the other hand. As shown in FIG. 72, when the holder 4 is connected to the main body 1, the protective housing 11 is located on the lateral outer side of the side wall 42 of the holder 4.

As shown in FIG. 68, the brake pipe protection device 10 further includes a protection connector 12. As shown in FIG. 69, the protection connector 12 includes a protection inner end 12a, a protection outer end 12b, and a protection between the two. Adapter 12c. As shown in Figure 73, the protective inner end 12a is located on the lower side of the holder 4 and abuts against the holder 4, specifically it can abut the pressure plate 412d of the holder 4; the protective outer end 12b is located at the lower side of the protective inner end 12a. It is laterally outside, and is rotatably connected with the main body 1, specifically, it can be rotatably connected with the support 61 of the main body 1.

As shown in Figure 73, during the connecting process of the holder 4 and the main body 1, the pressure of the holder 4 on the inner end of the protective end 12a gradually increases, so that the force on the inner end of the protective end 12a is gradually greater than that of the outer end of the protective end 12b. Gravity, at this time, the protective connector 12 rotates around the rotational connection position with the main body 1 (in the direction of the arrow in the figure), thereby driving the protective casing 11 to rotate upward and inward, resetting the protective casing 11, and finally arrives in Fig. 73 The location shown.

As shown in Figure 75, in the process of separating the holder 4 from the main body 1, the pressing force of the holder 4 on the protective inner end 12a is gradually reduced, so that the force of the protective inner end 12a is gradually smaller than that of the protective outer end 12b. Gravity, at this time, under the action of gravity, the protective connector 12 rotates around the rotational connection position with the main body 1 (in the direction of the arrow in the figure), thereby driving the protective casing 11 to rotate downward and outward, so that the protective casing 11 The height position of descent down, and finally reach the position shown in Figure 75. Here, when the brake pipe guard 10 is installed, the position of its center of gravity can be adjusted so that its center of gravity can be distributed laterally outside the center of rotation. In this way, once the brake pipe guard 10 is disconnected from the holder 4 , Which can produce the above form of rotation.

Since the height position of the protective shell 11 is lowered, it is only necessary to lift the support portion 4 upward for a short distance to avoid the interference of the protective shell 11 on the support portion 4, so that the support portion 4 can smoothly rotate around the vertical direction. Or pan in the horizontal direction.

In summary, during the separation process of the holder part 4 and the body part 1, the protective shell 11 can automatically rotate downward and outward to avoid the holder part 4, effectively shortening the lifting distance of the holder part 4; the holder part 4 and the body part 1 During the connection process, the protective housing 11 can be automatically reset. The shortening of the lifting distance and the automatic avoidance and automatic reset of the protective shell 11 improve the separation efficiency and connection efficiency of the support portion 4 and the main body portion 1.

Further, the brake protective gear 10 can also be provided with a first protective limiter 13 (see Figure 73 and Figure 76), and the first protective limiter 13 is fixed to the main body 1 and specifically can be fixed on the support 61, When the protective housing 11 rotates downwards and outwards to the limit position, the protective connecting piece 12 conflicts with the first protective limiting member 13, so as to prevent the risk of the protective housing 11 from turning downwards and causing difficulty in resetting. In the figure, the first protective limiter 13 is a block. In actual implementation, its structure and shape can be adjusted as needed, and it is not limited to the block.

Further, the brake tube protection device 10 may also be provided with a magnetic member 14 (see FIG. 68). When the protection housing 11 is located on the laterally outer side of the holder 4, the protection housing 11 passes through the magnetic member 14 and the holder 4 The side wall 42 is magnetically attracted. In this way, the on-vehicle vibration of the brake protection device can be alleviated, and the service life of the brake protection device 10 can be improved.

In the solution shown in the figure, the magnetic member 14 is detachably fixed on the upper surface of the protective housing 11, specifically, it can be fixed by bolts and nuts. Fixing the magnetic member 14 on the upper surface of the shielding case 11 can ensure that the direction of the magnetic force received by the shielding case 11 during the resetting process of the shielding case 11 is basically the same as the resetting direction of the shielding case 11, so that the magnetic force can be Assist the protective shell 11 to reset. The magnetic component 14 and the protective housing 11 are detachably fixed, which facilitates the replacement of the magnetic component 14.

Furthermore, the brake tube protection device 10 can also be provided with a second protection limiter 15 (see FIGS. 75 and 76). When the protection housing 11 is reset to the lateral outside of the holder 4, the protection connection member 12 and The second protective limit piece 15 conflicts. When the magnetic member 14 is provided, when the holder 4 moves upward, under the action of the magnetic force, the protective connector 12 tends to move upward accordingly. By setting the second protective limit member 15, the protective connector 12 can be prevented from following The support part 4 moves upward. In the figure, the second protective limiter 15 is a block. In actual implementation, its structure and shape can be adjusted as required, and it is not limited to the block.
