Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of this application.

The technical solution of the present application will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

Example one

FIG. 1 is a schematic structural diagram of a protective device provided by Embodiment 1 of the application. As shown in FIG. 1, the protective device of this embodiment is used for railway transportation vehicles and includes at least one guardrail assembly 100, which includes a horizontal railing 10, The lower guard 20, the locking assembly 30, and the rotating rail 50 are fixedly connected to the loading floor 200 of the railway transport vehicle. The rotating rail 50 is connected between the horizontal rail 10 and the lower protective member 20, and the rotating rail 50 is connected to The horizontal railing 10 is rotatably connected, and the rotating rail 50 is rotatably connected with the lower guard 20, so that the horizontal rail 10 can be rotated in a vertical plane relative to the lower guard 20 under the driving of the rotating rail 50, and the locking assembly 30 Set on the lower guard 20 or at least one rotating rail 50, the locking assembly 30 is used to limit the rotation angle of the rotating rail 50 relative to the lower guard 20 to a preset angle.

In the above solution, by making the rotating railing and the horizontal railing rotatably connected, and the rotating railing and the lower guard rotatably connected, the horizontal railing can be rotated relative to the lower guard under the driving of the rotating rail to adjust the height of the horizontal railing, The height of the horizontal railing can be fixed at the preset position by setting the locking component. Therefore, when the railway transport vehicle passes through the road condition with a curved surface at the top of a bridge hole, tunnel, etc., the horizontal railing is rotated relative to the lower guard to reduce the height of the horizontal railing. After passing through the bridge hole, tunnel, etc., the horizontal railing is relatively The lower guard rotates to increase the height of the horizontal railing, and the locking assembly is used to fix the height of the horizontal railing. Compared with the fixed guardrail in the prior art, the height of the guardrail assembly is set to be adjustable. It can not only pass through bridges, tunnels, etc., but also has a sufficiently safe height after passing through the guardrail assembly, which has good safety protection for people or goods. In addition, in the present application, the vertical plane on which the horizontal railing 10 rotates may specifically refer to the vertical plane passing through the part (the junction 51) connected to the lower guard 20 on the rotating railing 10 and parallel to the length direction of the railway transport vehicle. flat. Hereinafter, for ease of description, the vertical plane on which the horizontal railing 10 rotates is simply referred to as the vertical plane.

The protective device of this embodiment is used for railway transportation vehicles, particularly suitable for railway transportation vehicles for transporting automobiles, and can be specifically set on the load floor of the railway transportation vehicles. As mentioned above, railway transportation vehicles are generally divided into single-deck cars and double-deck cars, and the protective device of this embodiment is applicable to both single-deck cars and double-deck cars. The following takes a double-decker as an example to illustrate the loading process for the car. For the loading of the lower load floor, generally the staff sits in the driver's seat and drives the car to the lower load floor; for the loading of the upper load floor Generally, a transition board is set up between the ground and the upper cargo floor to form a transition slope between the ground and the upper cargo floor, and then the staff sits in the driver’s seat and drives the car along the transition slope to the upper cargo floor. On the floor. After the staff drives the car to the upper load floor, the position of the car must be fine-tuned. At this time, the protective device set on the upper load floor is used to protect the car and the personnel to prevent people or cars from being loaded. Fell on the cargo floor.

The protective device of this embodiment includes at least one guardrail assembly 100. In FIG. 1, the protective device includes two guardrail assemblies 100 as an example for illustration. In practice, one or more guardrail assemblies 100 can be selected according to the needs of safety protection. Each guardrail assembly 100 includes a horizontal railing 10, a lower guard 20, a locking assembly 30, and a rotating rail 50. The structure of the lower guard 20 is not limited, as long as it has a certain height and can play a protective role. The guard 20 is fixedly connected to the load floor 200 of the railway transport vehicle, that is, the lower guard 20 is fixed relative to the load floor 200. Therefore, even when the height of the lateral rail 10 is lowered (down), the lower guard 20 can Play a protective role, for example, when the height of the horizontal railing 10 needs to be reduced through bridge holes, tunnels, etc., it can also play a role in safety protection for goods such as cars.

The rotating railing 50 is connected between the horizontal railing 10 and the lower guard 20. The function of the rotating railing 50 is mainly to drive the horizontal railing 10 to rotate around the lower protecting member 20. Specifically, the rotating railing 50 and the horizontal railing 10 are rotatably connected, In addition, the rotating rail 50 and the lower guard 20 are rotatably connected, so that the horizontal rail 10 can rotate relative to the lower guard 20 in a vertical plane under the driving of the rotating rail 50. Here, the rotating connection between the rotating railing 50 and the horizontal railing 10 means that the rotating railing 50 can be rotated relative to the horizontal railing 10, for example, the rotating railing 50 can be hinged with the horizontal railing 10, or the rotating railing can be made by other known methods. 50 is rotatably connected with the horizontal railing 10, and the rotating rail 50 is rotatably connected with the lower guard 20. The rotating rail 50 can be hinged with the lower guard. In addition, the rotating rail 50 can be one or more. When the rotating rail 50 is one, when the rotating rail 50 rotates around the lower guard 20, the horizontal rail 10 will rotate around the lower protective member 20 under the drive of the rotating rail 50; when there are multiple rotating rails 50, the same horizontal rail 10 is connected to each rotating railing 50. Therefore, when at least one rotating railing 50 rotates around the lower guard 20, the remaining rotating railings 50 are linked by the horizontal railing 10, and the horizontal railings 10 are driven by each rotating railing 50. Rotate down around the lower guard 20. In the above process, as the horizontal railing 10 rotates around the lower guard 20, since the rotating rail 50 also rotates, the height of the entire guardrail assembly 100 can be changed from high to low or from low to high to facilitate passage through bridge holes, Tunnel etc.

In the example shown in FIG. 1, the rotating rail 50 and the horizontal rail 10 are both in a vertical plane, such as rotating in the plane where the paper surface is. In addition, FIG. 1 is illustrated by having one horizontal railing 10 as an example. In practice, multiple horizontal railings 10 may also be provided. For example, each horizontal railing 10 may be arranged at intervals in the height direction, and the relative positions of each horizontal railing The horizontal railing which is fixed and located on the lowermost side is rotatably connected with the above-mentioned rotating railing 50. In this way, the horizontal railing group composed of a plurality of horizontal railings 10 can rotate relative to the lower guard 21 by the driving of the rotating rails. Of course, in addition to the rotatably connected solution of the lowermost horizontal railing and the above-mentioned rotating rail 50, one of the multiple horizontal rails may also be rotatably connected with the above-mentioned rotating rail 50.

The locking assembly 30 is disposed on the lower guard 20 or at least one rotating rail 50, and the locking assembly 30 is used to limit the rotation angle of the rotating rail 50 relative to the lower guard 20 to a preset angle. As mentioned above, the rotating rail 50 and the horizontal rail 10 can be rotated. Therefore, it is necessary to fix the rotation of the horizontal rail 10 at a certain position. For example, when the horizontal rail 10 is rotated to the highest position, the height of the entire guardrail assembly 100 is the highest. Fixing the horizontal railing 10 at the above-mentioned highest position can achieve better safety protection for personnel or cars. When the horizontal railing 10 rotates to the lowest position, it is also necessary to fix the horizontal railing 10 at the corresponding position to prevent The horizontal railing 10 swayed from side to side, making noise and increasing insecurity. The aforementioned locking assembly 30 is used to limit the rotation angle of the rotating rail 50 relative to the lower guard 20 to a preset angle. The angle of rotation of the rotating rail 50 relative to the lower guard 20 represents the degree of rotation of the rotating rail 50 relative to the lower guard. Since the lower guard 20 is fixed, the rotating rail 50 and the vertical can be used as shown in FIG. Characterized by the angle α in the straight direction. Corresponding to when the horizontal railing 10 is at the highest position, the α angle is 180°. Of course, the application is not limited to this, and the angle between the rotating rail 50 and the horizontal direction can also be used for characterization. Such changes fall within the protection scope of this application.

In practice, in order to reduce the weight of railway transport vehicles, the lower guard 20 can generally be provided with a structure with multiple rails. Optionally, the lower guard 20 can include a plurality of longitudinal rails 21 arranged at intervals, and a plurality of longitudinal rails 21 The railing 21 is fixedly connected to the load floor 200 of the railway transport vehicle. The longitudinal direction in the above-mentioned longitudinal railing 21 refers to the vertical direction, and the length direction of the longitudinal railing 21 is roughly arranged in the vertical direction. Of course, the length of the longitudinal railing 21 is actually The direction may also have a small angle with the vertical direction, and such transformations fall within the protection scope of this application. The longitudinal railings 21 are arranged at intervals, and the size of the interval between the longitudinal railings 21 can be set according to actual needs. The longitudinal railing 21 needs to be fixed relative to the loading floor 200. As shown in Figure 1, one end of each longitudinal railing 21 is fixed to the loading floor 200, which can be welded or fixedly connected to the loading floor by bolts or the like. 200 up. When the longitudinal railing 21 is fixed on the load floor 200, even if the horizontal railing 10 and the rotating railing 50 rotate and descend, due to the protective effect of the longitudinal railing 21, the cargo can be safely protected when passing through bridge holes, tunnels, etc.

The rotating railing 50 is connected between the horizontal railing 10 and the at least one longitudinal railing 21. Specifically, the rotating railing 50 is rotatably connected to the horizontal railing 10, and the rotating railing 50 is rotatably connected to the longitudinal railing 21, so that the horizontal railing 10 can Driven by the rotating railing 50, it rotates in a vertical plane relative to the longitudinal railing 21. Here, the rotating railing 50 and the longitudinal railing 21 can be rotatably connected by the rotating railing 50 and the longitudinal railing 21 hinged, in addition, the rotating railing 50 can be one It can also be multiple. When there is one rotating railing 50, it can be connected between the horizontal railing 10 and one of the longitudinal railings 21. When the rotating railing 50 rotates around the longitudinal railing 21, the horizontal railing 10 is rotating the railing 50. Drive down to rotate around the longitudinal railing 21; when there are multiple rotating railings 50, the same horizontal railing 10 is connected to each rotating railing 50, and each vertical railing 21 and the horizontal railing 10 can each connect a rotating railing 50, It is also possible that a rotating rail 50 is connected between each of a part of the longitudinal railing 21 and the horizontal railing 10. Therefore, when at least one rotating railing 50 rotates around the longitudinal railing 21, the remaining rotating railings 50 are rotated around their corresponding longitudinal rails 21 due to the action of the horizontal railing 10, and the horizontal railings 10 are driven by each rotating railing 50. Rotate around the longitudinal rail 21. In the above process, as the horizontal railing 10 rotates around the longitudinal railing 21, since the rotating rail 50 also rotates, the height of the entire guardrail assembly 100 can be changed from high to low or from low to high to facilitate passage through bridge holes and tunnels. Wait.

In addition, as described above, it is necessary to fix the rotation of the horizontal railing 10 at a certain position. Specifically, the locking assembly 30 is provided on the rotating railing 50 or the longitudinal railing 21, and the locking assembly 30 is used to oppose the rotating railing 50. The rotation angle of the corresponding longitudinal rail 21 is limited to a preset angle. The aforementioned locking assembly 30 is used to limit the rotation angle of the rotating rail 50 relative to the longitudinal rail 21 to a preset angle. The angle of rotation of the rotating railing 50 relative to the longitudinal railing 21 represents the degree of rotation of the rotating railing 50 relative to the longitudinal railing 21. Since the longitudinal railing 21 is fixed, the rotating railing 50 and the vertical direction can be used as shown in FIG. The included angle α to characterize. Corresponding to when the horizontal railing 10 is at the highest position, the α angle is 180°. Of course, the application is not limited to this, and the angle between the rotating rail 50 and the horizontal direction can also be used for characterization. Such changes fall within the protection scope of this application.

The detailed structure of the locking assembly 30 is described below. FIG. 2 is a schematic diagram of the structure of the locking assembly in the protective device provided in the first embodiment of the application. As shown in FIG. 2, the locking assembly 30 optionally includes a locking rod 31 and The reversing block 32, the locking rod 31 is arranged on the longitudinal railing 21, the reversing block 32 is fixedly connected to the rotating railing 50, the reversing block 32 is provided with an insertion hole 33, and the locking rod 31 can be arranged along the longitudinal rail 21 Move in the length direction to be inserted into or disconnected from the insertion hole 33 of the reversing block 32. Here, the locking rod 31 can be arranged inside the longitudinal railing 21. Since the reversing block 32 is fixed on the rotating railing 50 and the locking bar 31 is arranged on the longitudinal railing 21, when the locking bar 31 is close to the rotating railing 50 along the length of the longitudinal railing 21, and inserted into the reversing block 32 When inserted into the hole 33, the reversing block 32 cannot rotate relative to the locking rod 31, so the rotating rail 50 cannot rotate relative to the longitudinal rail 21, so the relative positions of the rotating rail 50 and the longitudinal rail 21 can be limited. Conversely, when the locking rod 31 is away from the rotating rail 50 along the length of the longitudinal rail 21 and is disconnected from the insertion hole 33 of the reversing block 32, the reversing block 32 is in a position that can rotate relative to the locking rod 31. Therefore, the rotating rail 50 can also be rotated relative to the longitudinal rail 21, so the rotating rail 50 can be rotated relative to the longitudinal rail 21.

The position and number of the insertion holes of the locking rod 31 directly affect the rotation angle of the rotating rail 50 relative to the longitudinal rail 21. As shown in FIG. 2, as an alternative embodiment, the insertion hole 33 includes a first insertion hole 34. The inner diameter of the first insertion hole 34 matches the outer diameter of the locking rod 31, and the first insertion hole The axis of the hole 34 is along the length of the rotating rail 50, and the length of the locking bar 31 is along the length of the longitudinal rail 21. With this arrangement, when the locking rod 31 approaches the rotating rail 50 along the length of the longitudinal rail 21 and is inserted into the first insertion hole 34 of the reversing block 32, the reversing block 32 cannot rotate relative to the locking rod 31 Therefore, the rotating rail 50 cannot rotate relative to the longitudinal rail 21. Since the axis of the first insertion hole 34 is along the length of the rotating rail 50, the length of the locking lever 31 is along the length of the longitudinal rail 21. When the end of 31 is inserted into the first insertion hole 34, the length direction of the rotating rail 50 is consistent with that of the longitudinal rail 21. If the longitudinal rail is vertically fixed on the loading floor 200, the rotating The railing 50 is also erected vertically. Conversely, when the locking rod 31 is away from the rotating rail 50 along the length of the longitudinal rail 21 and is disconnected from the first insertion hole 34 of the reversing block 32, the reversing block 32 is capable of rotating relative to the locking rod 31 As a result, the rotating rail 50 is also in a state capable of rotating relative to the longitudinal rail 21, so the rotating rail 50 can be rotated relative to the longitudinal rail 21.

The following describes the realization structure of the locking rod 31 reciprocating along the length direction of the longitudinal rail 21. Optionally, the locking assembly 30 further includes a guide sleeve 36 and a return spring 37. The guide sleeve 36 is fixedly connected to the longitudinal rail 21, and the guide sleeve 36 is sleeved on the outside of the locking rod 31 to oppose the locking rod 31. The return spring 37 is sleeved on the outside of the locking rod 31, and an upper limit block 38 is provided on the locking rod 31. One end of the return spring 37 abuts on the upper limit block 38 , The other end abuts on the guide sleeve 36, and the return spring 37 is in a compressed state when the locking rod 31 and the insertion hole 33, such as the first insertion hole 34, are disengaged from the insertion, so as to produce a close insertion of the upper limit block 38 Holes such as the thrust of the first plug hole 34.

The guide sleeve 36 can be fixed on the longitudinal railing 21 by screws or the like. The guide sleeve 36 can be provided with a through hole to be sleeved on the outside of the locking rod 31. Of course, the axial direction of the through hole can be along the longitudinal rail 21 The longitudinal direction is used to guide the movement of the locking rod 31 along the longitudinal direction of the longitudinal rail 21. In addition, since the return spring 37 is in a compressed state when the first insertion hole 34 of the locking rod 31 is disengaged from the insertion, the upper limit block 38 will be pushed close to the insertion hole such as the first insertion hole 34 at this time.

In addition, optionally, the locking assembly 30 further includes a joystick 39 and a counterweight 35. The middle of the joystick 39 is hinged to the longitudinal rail 21, and one end of the joystick 39 and the end of the locking rod 31 away from the insertion hole 33 are hinged. Hinged, the other end of the joystick 39 is connected with the counterweight 35. Specifically, the joystick 39 is a member operated by human hands. When the locking rod 31 is arranged inside the longitudinal railing 21, the joystick 39 can be inserted on the longitudinal railing and at least part of the structure is exposed outside the longitudinal railing 21 Of course, on the longitudinal railing 21, at the junction of the joystick 39 and the longitudinal rail, there is also an avoiding portion (not shown) for the joystick 39 to move. The middle part of the joystick 39 and the longitudinal rail 21 are hinged at the hinge point 40, so that the joystick 39 can rotate about the hinge point 40. Therefore, when one end of the joystick 39 and the end of the locking rod 31 away from the insertion hole 33 are hinged, and the other end of the joystick 39 is connected to the counterweight 35, the lock rod 31 can be completed by operating the joystick 39 The reciprocating movement. In addition, the hinge point may be a point on the support 22. Specifically, a support 22 is also fixedly connected to the lower part of the longitudinal rail 21, and one end of the support 22 is the hinge point 40.

The following takes the insertion of the locking rod 31 and the first insertion hole 34 as an example to introduce the detailed process of the reciprocating movement of the locking rod 31 along the longitudinal direction of the longitudinal rail 21. As shown in Figure 2, when the end of the joystick 39 away from the counterweight 35 is pulled downward (away from the first insertion hole 34), the joystick 39 rotates around the hinge point 40, and the joystick 39 drives the lock The closing rod moves in a direction away from the first insertion hole 34 (that is, the downward direction in FIG. 2). At this time, the upper limit block 38 moves downward along with the locking rod 31, and generates a pressing force on the return spring 37 Since the other end of the return spring 37 abuts on the side of the guide sleeve 36, the other end cannot move. The upper limit block 38 exerts a pressing force on the return spring 37 to compress the return spring 37. At this time, as the lock is closed The rod 31 further moves downward and is disconnected from the first insertion hole 34. Conversely, when the joystick 39 is no longer pulled, on the one hand, when the compressed return spring 37 returns to its original shape, it generates a thrust on the upper limit block 38 in the direction close to the first insertion hole 34, so that the locking lever 31 has a direction The tendency of moving closer to the first insertion hole 34, on the other hand, the counterweight 35 moves away from the first insertion hole 34 due to its own gravity, so that the joystick rotates around the hinge point 40, thereby, the joystick The end of 39 away from the weight 35 moves toward the first insertion hole 34, driving the locking rod 31 to move toward the first insertion hole 34, so that the locking rod 31 approaches the first insertion hole. Moves in the direction of 34, and is inserted into the first insertion hole 34.

The following describes the connection method of the rotating railing 50 and the longitudinal railing 21. FIG. 3 is a schematic diagram of the structure of the first rotating component in the protective device provided in the first embodiment of the application. As shown in FIG. 3, as an optional implementation, the guardrail The assembly 100 further includes a first rotating assembly 60. The first rotating assembly includes a first rotating shaft 61 and a first rotating shaft seat 62. The first rotating shaft seat 62 is fixedly connected to the longitudinal rail 21. The reversing block 32 passes through the first rotating shaft 61 and the first rotating shaft. The rotating shaft base 62 is hinged so that the rotating rail 50 can rotate relative to the longitudinal rail 21. The axis of the first rotating shaft 61 is along the width direction of the railway transportation vehicle. A through-hole through which the locking rod 31 can penetrate is formed on the first rotating shaft base 61孔63. Specifically, the first rotating shaft 61 penetrates the first rotating shaft seat 62 and the reversing block 32 fixed on the rotating rail 50 at the same time, so that the rotating rail 50 and the first rotating shaft seat 62 are hinged. In addition, the through hole 63 formed on the first rotating shaft seat 61 can allow the locking rod 31 to penetrate therethrough.

Figure 4 is a schematic structural diagram of the guardrail assembly in the protective device provided by Embodiment 1 of the application. Figure 5 is a partial enlarged view of part A in Figure 4, and Figure 6 is a partial enlarged view of part B in Figure 4, as shown in Figure 5. It is shown that in practice, the reversing block 32 is arranged in the first rotating shaft seat 62. The locking rod 31 passes through the through hole 63 and is inserted into the first insertion hole 34.

In addition, in actual operation, when the rotating rail 50 drives the horizontal rail 10 to rotate, for example, when the length and the horizontal direction of the rotating rail 50 are approximately parallel, the position of the rotating rail 50 can be limited here. Specifically, as As shown in FIG. 4, the guardrail assembly 100 further includes a first limiting member 64 disposed on at least one longitudinal rail 21. The top of the first limiting member 64 has a bearing surface 65 for bearing the rotating rail 50, and the bearing surface 65 is horizontally arranged . Specifically, when the rotating railing 50 described in FIG. 4 rotates counterclockwise in a vertical plane around the longitudinal railing 21, when the rotating railing 50 rotates to a horizontal position, it contacts the bearing surface 65 of the first limiting member 64, And supported on the bearing surface 65, the position of the rotating rail 50 can be limited to this horizontal position, instead of continuing to rotate counterclockwise.

In addition, in the case where the same guardrail assembly 100 includes multiple first limiting members 64, the multiple first limiting members 64 are located on the same side of the corresponding longitudinal rail 21 on the vertical plane. For example, in FIG. 4, in the case where the first limiting member 64 is provided on the first and second longitudinal railings 21 from the right, each first limiting member is located on its corresponding longitudinal railing 21 is on the left side, so that each rotating rail 50 can stop rotating when it rotates counterclockwise to the horizontal position.

In addition, in order to further enhance the stability of the rotating rail 50 at the horizontal position, optionally, the insertion hole 33 includes a second insertion hole 66, and the inner diameter of the second insertion hole 66 matches the outer diameter of the locking rod 31 The axis of the second insertion hole 66 is perpendicular to the length direction of the rotating railing 50. When the locking rod 31 is inserted into the second insertion hole 66, the rotating railing 50 is placed on the bearing surface 65. In FIG. 5, if the turning rail 50 is rotated counterclockwise to the horizontal position, the second insertion hole 66 is vertically downward, because the intersection of the axis of the second insertion hole 66 and the axis of the first insertion hole 34 passes through the first The center of rotation of a rotating shaft 61, therefore, the locking rod 31 can just be inserted into the second insertion hole 66, and at this time, the rotating rail 50 can just be placed on the bearing surface 65, so the The positioning includes both the locking rod 31 and the first limiting member 64, so the positioning of the rotating rail 50 is more reliable.

In addition, as shown in FIG. 5, optionally, the guardrail assembly 100 further includes a second limiting member 67 disposed on at least one rotating railing, and the second limiting member 67 has a locking member that is parallel to the length direction of the rotating rail 50. The locking surface 68 is perpendicular to the first plane. When the locking rod 31 is inserted into the first insertion hole 34, the locking surface 68 and the first rotating shaft seat 62 are located in the direction of rotation of the rotating rail 50 The side surfaces abut against each other, and the locking surface 68 and the bearing surface 65 are located on different sides of the corresponding longitudinal railing 21 on the vertical plane. Specifically, as shown in FIG. 5, the second limiting member 67 may be a plate-shaped member with a substantially S-shaped cross-section, one end of which is connected to the reversing block 32, and the other end extends downward, when the locking lever When 31 is inserted into the first insertion hole 34, the locking surface 68 abuts against the right side of the first shaft seat 62 to limit the rightward rotation of the rotating rail 50 on the vertical plane, that is, to limit the clockwise direction In addition, the locking surface 68 abuts against the left side surface of the first rotating shaft seat 62, which can limit the leftward rotation of the rotating rail 50 on the vertical plane, that is, limit the counterclockwise rotation. Of course, the locking surface 68 and the bearing surface 65 are located on different sides of the corresponding longitudinal railing 21 in the vertical plane. For example, in FIG. 4, the second limit position is provided on the first longitudinal rail 21 from the right. Member 67, and in the case where the first limiting member 64 is provided on the second longitudinal rail 21 from the right, the locking surface 68 on the second limiting member 67 is located on the right side of the corresponding longitudinal rail 21, The bearing surface 65 on the first limiting member 64 is located on the left side of the corresponding longitudinal rail 21.

Of course, the protective device may include multiple guardrail assemblies 100. Optionally, multiple guardrail assemblies 100 are arranged at intervals on a vertical plane. Among at least two adjacent guardrail assemblies 100, one of the guardrail assemblies 100 is The included bearing surface 65 and the bearing surface 65 included in another guardrail assembly are located on different sides of the corresponding longitudinal railing 21 on the vertical plane. In addition, the locking surface included in one of the guardrail assemblies 100 and the locking surface included in the other guardrail assembly are also located on different sides of the corresponding longitudinal rail 21 on the vertical plane. In this way, two adjacent guardrail assemblies can fall down in different directions. In addition, there is no limit to the position of the locking surface and the bearing surface, as long as the two are included in the same guardrail assembly, and they can be arranged on the corresponding longitudinal or horizontal railings. It can also be arranged on a longitudinal railing or a horizontal railing that does not correspond to each other. For example, in FIG. 4, the bearing surface (the first limiting member) is arranged on the longitudinal railing 21 second from the right, and the locking surface (the second The stopper) is arranged on the longitudinal rail 50 first from the right.

In addition, FIG. 7 is a partial enlarged view of the C component of FIG. 1. As shown in FIG. 7, in order to facilitate the smooth lifting of the rotating railing 50 in the down state, a resetting assembly can also be provided. The resetting assembly includes a tension spring 70 and The return piece 71, one end of the tension spring 70 is fixedly connected to the load floor 200 or the longitudinal railing 21, one end of the return piece 71 is fixedly connected to the rotating rail 50, and the other end of the return piece 71 is fixedly connected to the other end of the tension spring 70 to reset The sheet 71 and the tension spring 70 and the bearing surface 65 are located on different sides of the corresponding longitudinal railing 21 on the vertical plane. As shown in Figures 1 and 7, when the rotating railing 50 is turned to the right, the extension spring 70 is in a stretched state. Therefore, when the rotating railing 50 needs to be reset, the extension spring generates a restoring force on the rotating railing 50 to assist Rotate the rail 50 to reset, that is, return to the vertical position.

In addition, in this application, as shown in FIG. 9, the upward direction of the paper is defined as upward, the leftward direction of the paper is defined as left, the downward direction of the paper is defined as downward, and the paper faces the right direction. The rule is right.

The second rotating shaft seat 83 is fixedly connected to the horizontal rail 10, the adapter 82 is fixedly connected to the rotating rail 50, and the second rotating shaft seat 83 passes through The second rotating shaft 81 and the adapter 82 are hinged, so that the lateral rail 10 can rotate relative to the rotating rail 50, and the axis of the second rotating shaft 81 is along the width direction of the railway transportation vehicle. In FIG. 8, the second rotating shaft 81 passes through the adapter 82 and the second rotating shaft seat 83 at the same time, so that the adapter 82 and the second rotating shaft seat 83 are hinged.

FIG. 9 is a schematic structural diagram of the guardrail component of the protective device provided in Embodiment 1 of the application when the guardrail assembly is laid down. As shown in FIG. 9, optionally, the rotating railing 50 includes a first rotating railing 84, and the first rotating railing 84 is connected to the Among the longitudinal railings 21, they are arranged between the outermost longitudinal railing 21 and the horizontal railing 10. The first rotating railing 84 includes a first link 85 and a second link 86. One end of the first link 85 and the horizontal railing 10 Hinged, one end of the second link 86 is hinged to the longitudinal rail 21, and the other end of the first link 85 is hinged to the other end of the second link 86, so that the first link 85 can be positioned relative to the second link 86 Rotate in the vertical plane. By setting the first link 85 to be able to rotate relative to the second link 86, when the first rotating rail 84 is down, the first link 85 is rotated relative to the second link 86, which is equivalent to The rotating rail 84 is folded, and compared with the integrally formed rotating rail 50, the space occupied by the rotating rail is greatly reduced. Of course, this effect is more obvious when the first rotating rail 84 is arranged at the end.

In addition, in order to further reduce the space occupied by the first connecting rod, at least part of the structure on the first connecting rod 85 may be bent to form the bent portion 87. The bent portion 87 may be arranged at a right angle. In this way, as shown in FIG. 9, the first connecting rod 85 in a right-angle shape can be supported on the load floor 200 by using one side of the right-angle bent portion 87.

In addition, in order to further increase the safety protection of the guardrail assembly 100, a safety rope 88 may be provided, as shown in FIG. 1. Optionally, the guardrail assembly 100 further includes a safety rope 88, which is located under the horizontal railing 10, and Each rotating rail 50 is fixedly connected with a safety rope 88. In this way, when the guardrail assembly 100 shown in FIG. 1 is erected, the safety rope 88 is located between the lateral railing 10 and the load floor 200, which can assist in the excessively large gap between the lateral rail 10 and the load floor 200 Protection. Of course, as shown in FIG. 9, when the guardrail assembly 100 is put down, the safety rope 88 has a certain degree of elasticity and is put down together with the turning of the rail 50.

The following briefly introduces the working process of the protection component of this embodiment. As shown in FIG. 1, when the locking rod 31 is inserted into the first insertion hole 34, both the rotating rail 50 and the longitudinal rail 21 are in an upright state relative to the load floor 200, and the horizontal rail 10 is at the highest position at this time. It can be applied to safety protection under general conditions. When the end of the joystick 39 away from the counterweight 35 is pulled downward (the direction away from the first insertion hole 34), the joystick 39 rotates around the hinge point 40, and at the same time, the joystick 39 drives the locking rod 31 to move away from the first insertion hole 34. Moves in the direction of a plug hole 34. At this time, the upper limit block 38 moves downward along with the locking rod 31, and generates a pressing force on the return spring 37, because the other end of the return spring 37 abuts on the guide sleeve 36 On the side, the other end cannot move. The upper limit block 38 exerts a pressing force on the return spring 37 to compress the return spring 37. At this time, as the locking rod 31 further moves downward, it is connected to the first insertion hole. 34 Disconnect from the plug. At this time, the longitudinal railing 21 of the rotating railing 50 is out of lock. For the railing assembly 100 on the left in FIG. 1, since the second limiting member 67 is provided on the right side of the corresponding longitudinal railing 21, the locking surface 68 faces the second rotating shaft. The right side of the seat 83 is limited, so the guardrail assembly 100 on the left cannot rotate to the right. The staff rotates the rotating rail 50 around the longitudinal rail 21 to the left. At the same time, the multiple rotating rails 50 drive the horizontal rail 10 to the When the rotating rail 50 rotates to the horizontal position, it contacts the bearing surface 65 of the first limiting member 64 and is supported on the bearing surface 65. The position of the rotating rail 50 can be limited to the horizontal position without Continue to rotate counterclockwise. At the same time, the first connecting rod 85 at the end rotates relative to the second connecting rod 86, which is equivalent to folding the first rotating rail 84, reducing the length of the first rotating rail 84 in the rail transport vehicle. The space occupied by the above. In addition, it should be noted that in the above process, the hand of the worker always pulls the operating rod 39 away from the first insertion hole 34 to prevent the locking rod 31 from abutting on the reversing block 32. When the rotating rail 50 is placed on the bearing surface 65, at this time, the joystick 39 is no longer pulled. On the one hand, when the return spring 37 in the compressed state returns to its original shape, the upper limit block 38 is close to the second insertion hole 66 The thrust in the direction of, the locking rod 31 has a tendency to move closer to the second insertion hole 66. On the other hand, the counterweight 35 moves away from the second insertion hole 66 due to its own gravity, making the manipulation The lever rotates around the hinge point 40, whereby the end of the lever 39 away from the counterweight 35 moves toward the second insertion hole 66, driving the locking lever 31 to move toward the second insertion hole 66, As a result, the locking rod 31 moves in a direction close to the second insertion hole 66 and is inserted into the second insertion hole 66. At this time, relying on the insertion of the first limiting member 64 and the locking rod 31 with the second insertion hole 66, the rotating rail 50 is limited to a horizontal position. At this time, it is suitable for the situation where railway transport vehicles pass through bridge holes, tunnels, etc. After passing through the bridge tunnel and tunnel, the guardrail assembly 100 can be erected again according to actual needs. This process is exactly the opposite of the above-mentioned process of laying down, and will not be repeated here. In addition, the above description takes the guardrail assembly 100 on the left in FIG. 1 as an example. For the guardrail assembly on the right side, its laying down direction is exactly the opposite of that of the guardrail assembly on the left, and its operation is similar to that of the guardrail assembly on the left. , I won’t repeat it here.

The protective device of this embodiment is used for railway transportation vehicles. The protective device includes at least one guardrail assembly.
