Description
Technical Field
The invention relates to the technical field of railway vehicles, in particular to an electric coupler pushing device.
Background
The front end part of the vehicle mainly completes the coupling, communication and the like between two vehicles, and the coupler buffer part is arranged at the front end of the vehicle. With the development of rail transit technology, the control functions required by vehicles are more and more, and the front end parts and components of the vehicles are increased, so that the installation space of the conventional vehicle coupler is required to be smaller and smaller, and the requirement on the structural compactness of the front end coupler buffer device is higher and higher. The requirements of quick reconnection and flexible grouping also enable more and more items of electric car couplers to be required on the coupler buffer device on the middle section of the car, and the coupler buffer device on the middle section is limited by factors such as a car through passage above the coupler buffer device or a height limit of the lower part of the coupler buffer device, so that the requirement on the compactness of the structure of the coupler buffer device is higher.
The electric coupler pushing device is used for pushing an electric coupler of the coupler to complete coupling of the coupler and is configured at the front end of the vehicle. Two typical structures of the existing electric coupler pushing mechanism are as follows: cylinder direct push type structure, reverse push type auto-lock propelling movement structure.
The cylinder direct-pushing type structure principle is simple, the driving mechanism, the pushing rod and the electric coupler are linearly arranged, parts are few, reliability is high, occupied space is large, self-locking is not easy to set, or the structure is too overstaffed after self-locking is set, and unlocking is not smooth at certain risk.
The typical structure of the reverse-pushing type self-locking pushing structure has the following advantages and disadvantages. For example, in the pushing structure disclosed in patent No. CN103818403B, the pushing structure is formed by coupling a plurality of rods, and after the pushing structure is pushed in place, no straightening locking mechanism is provided, the pushing rod connected to the electrical coupler is prone to tilt, the pushing force does not have an upward inclination component horizontally with the longitudinal center line direction of the coupler, and the connecting surface of the two connected electrical couplers is prone to form a bell mouth, which results in unstable connecting signals; as the pushing structure disclosed in patent No. CN101698413A, the mechanism has a compact structure, the pushing force is parallel to the longitudinal centerline of the car coupler after pushing in place, and the signal is stable after connection, but the structure needs a larger pushing force compared with a direct pushing structure; other reverse-pushing self-locking pushing mechanisms which are commonly used at present occupy larger car coupler space.

The invention provides an electric coupler pushing device which is used for pushing an electric coupler 1 and assisting in coupling of the electric coupler during connection of the coupler. Electric coupling pusher is connected with electric coupling 1, and electric coupling 1 is disposed on propelling movement track 5, is pushed out and withdraws by electric coupling pusher control, and electric coupling pusher mainly includes:
a support frame 12;
auxiliary supporting structure: comprises an auxiliary supporting rod 3 which is connected with a supporting frame 12 by a shaft;
a driving mechanism: the device comprises a mounting end and a power output end, wherein the mounting end is rotatably mounted on a support frame 12, and the power output end is connected to an auxiliary support rod 3; in the embodiment, the driving mechanism adopts the driving cylinder 4, the mounting position between the cylinder 4 and the support frame 12 forms the cylinder rotating shaft 11, and the auxiliary support rod 3 can rotate around the connecting shaft between the auxiliary support rod and the support frame 12 in the stretching process of the cylinder rod;
a force transmission mechanism: comprises a push rod 2; one end of the push rod 2 is rotatably connected with the electric coupler 1, the joint of the push rod and the electric coupler is a first push rod rotating shaft 7, the other end of the push rod 2 is in shaft connection with the auxiliary supporting rod 3, and the joint of the push rod and the auxiliary supporting rod is a second push rod rotating shaft 8; the pushing rod 2 is an elastic rod to realize a stable pushing effect;
the drive mechanism is configured to retract the electrical coupler 1 when the drive strut 3 is moved to a side closer to the coupler longitudinal centerline 13.
Example 1
Referring to fig. 1 and 2, which are schematic structural views of a first embodiment of the present invention, the auxiliary supporting rod 3 is a straight rod. Fig. 1 is a schematic diagram of an extended state of an electric coupler, and it can be seen from the diagram that a cylinder 4 applies an acting force to an auxiliary support rod 3, and the auxiliary support rod 3 has both force transmission and pushing support functions. When the cylinder 4 extends out, the supporting rod 3 is pushed to the direction far away from the longitudinal center line of the vehicle, the supporting rod 3 rotates around the shaft joint of the supporting rod and the supporting frame 12, and the electric coupler 1 is pushed out; when the cylinder 4 retracts, the supporting rod 3 is pulled towards the direction close to the longitudinal center line of the vehicle, the supporting rod 3 rotates around the shaft joint of the supporting rod and the supporting frame 12, and the electric coupler 1 is pulled back.
The cylinder 4 is located on the side close to the longitudinal center line 13 of the coupler relative to the connecting point of the auxiliary support rod 3 and the support frame 12, i.e., the first rotating shaft 10 of the auxiliary support rod. The driving form of the air cylinder 4 can save the action space in the pushing process, so that the structure of the pushing device is more compact.
In the horizontal direction, the joint of the auxiliary support rod 3 and the support frame is positioned on one side closer to the longitudinal center line 13 of the coupler relative to the joint of the push rod and the electric coupler. That is, the auxiliary support rod first rotary shaft 10 is located on the side closer to the longitudinal center line of the coupler with respect to the pushing rod first rotary shaft 7, and this structure enables the electric coupler 1 to be pushed into place and then to be locked.
More specifically, the cylinder 4 and the auxiliary support rod 3 are configured such that the push rod 2 is in a horizontal state when the electric coupler 1 is pushed into position. Through the adjustment drive actuating cylinder 4 mounted position on support frame 12, the size of auxiliary stay pole 3 and mounted position on support frame 12, can realize that first force transmission part is released the back, with push rod 2 propelling movement to the level, and then can make electric coupling 1 by propelling movement to the level, no slope contained angle between push rod 2 and the electric coupling 1 guarantees the stability that the coupling links and hangs.
The cylinder 4 is further configured such that when the electric coupler 1 is pushed into position, the driving stroke of the cylinder 4 reaches a limit to achieve a drive lock. The limit mentioned here means that the pushing stroke of the pushing mechanism reaches the maximum, and for the cylinder 4, the cylinder rod extends to the maximum. Specifically, in the present embodiment, when the electric coupler 1 is pushed out, the cylinder rod extends to the maximum stroke, and at this time, the push rod 2 is in the horizontal state, so that the push-out locking is realized.
Example 2
The auxiliary support rod 3 is a V-shaped rod, the first rod body 301 end of the V-shaped rod is connected with the pushing rod 2 in a shaft mode, the second rod body end 302 of the V-shaped rod is connected with the power output end of the air cylinder 4, the connection position of the first rod body end and the second rod body end is an auxiliary support rod second rotating shaft 9, and the included angle end of the V-shaped rod is rotatably installed on the support frame 12 and serves as an auxiliary support rod first rotating shaft 10. The "V" shaped bar may be of one piece construction, see fig. 4, or of two sections rigidly joined together.
In order to realize self-locking after the electric coupler 1 is pushed out in place, the joint of the V-shaped rod and the supporting frame 12 is arranged on one side closer to the longitudinal center line 13 of the coupler relative to the joint of the push rod and the electric coupler in the horizontal direction. In a colloquial way, the shaft contact points of the "V" shaped lever and the supporting bracket 12 and the shaft contact points of the push lever 2 and the electric coupler 1 are not on the same horizontal straight line, i.e. the auxiliary supporting lever first rotating shaft 10 is located on the side closer to the longitudinal centre line of the coupler relative to the push lever first rotating shaft 7. This way a self-locking can be formed after the electric coupler 1 has been pushed into place.
As in embodiment 1, the drive mechanism and the auxiliary support structure are configured such that the push rod 2 is in a horizontal state when the electric coupler is pushed into position. This can be achieved by adjusting the length and mounting position of the cylinder 4 and the auxiliary support bar 3 in the auxiliary support structure.
The structure refers to fig. 3 to fig. 6, which are schematic structural diagrams of an electric coupler pushing device according to a second embodiment. Fig. 3 and 4 correspond to one embodiment, fig. 5 and 6 correspond to another embodiment, and the two embodiments are different in that the mounting position of the cylinder 4 is different.
As shown in fig. 3 and 4, the driving cylinder 4 is located at a position opposite to the first rotation shaft 10 of the auxiliary support rod, which is located at a side away from the electric coupler 1, i.e., at a right side of the first rotation shaft 10 of the auxiliary support rod.
After the electric coupler 1 is pushed out to the right, as shown in fig. 3, the driving cylinder 4 extends to the maximum stroke position, and at the moment, the pushing rod 2 is in the direction parallel to the longitudinal center line 13 of the coupler; the connecting shaft of the push rod 2 and the V-shaped rod is located on one side far away from the longitudinal central line 13 of the car coupler relative to the connecting line of the push rod 2, the electric car coupler connecting shaft and the V-shaped rod and the supporting frame connecting shaft, and the description is combined with the attached drawing, namely, the second rotating shaft 8 of the push rod and the longitudinal central line 13 of the car coupler are respectively located on two sides of the connecting line of the first rotating shaft 7 of the push rod and the first rotating shaft 10 of the auxiliary supporting rod. The angle a between the push rod 2 and the line connecting the side of the "V" shaped rod to which it is connected is greater than 180 °, in this embodiment 185 °. Because the included angle a is larger than 180 degrees, when an external force pushes the electric coupler 1, the V-shaped rod tends to rotate towards the opposite side relative to the longitudinal central line 13 of the coupler, the driving cylinder 4 tends to be pulled, and at the moment, the driving cylinder 4 extends to the maximum stroke position and cannot extend continuously to prevent the rotating arm from rotating towards the opposite side of the longitudinal central line 13 of the coupler, so that the electric coupler 1 is prevented from retracting, and self-locking is formed.
When the electric coupler 1 retracts, as shown in fig. 4, the driving cylinder 4 retracts, and the V-shaped rod is driven to rotate towards the longitudinal center line 13 of the coupler, so that the electric coupler is retracted, and after the electric coupler is completely retracted, as shown in fig. 3. When the electric coupler retracts, the V-shaped rod rotates towards one side of the longitudinal central line 13 of the coupler, and the retracted V-shaped rod 3 does not occupy more space than the electric coupler 1 in a state after being pushed out in place, so that the space above the pushing mechanism of the electric coupler 1 is more compact.
As shown in fig. 5 and 6, the mounting point of the driving cylinder 4 with respect to the first force transmission unit and the support bracket 12, i.e., the position of the rotary shaft 10, is located on the side close to the electric coupler 1, i.e., the left side of the rotary shaft 10 as shown. The principle of pushing, self-locking and retracting of this implementation structure is similar to the above-described embodiments, except that when the driving cylinder 4 retracts, the electric coupler 1 is pushed out; when the driving cylinder 4 extends, the electric coupler 1 retracts. The improved structure has the advantages that compared with the first embodiment: in the embodiment, the retraction of the electric coupler 1 is driven by the retraction of the driving cylinder 4, the electric coupler 1 needs to be unlocked when being retracted, and meanwhile, the two connected electric couplers 1 have certain adhesion force, so that a larger driving force is often needed when the electric coupler 1 is retracted; and because the driving force when the driving cylinder 4 extends is larger than the driving force when the driving cylinder retracts, the driving force when the electric coupler 1 retracts is improved by driving the electric coupler 1 to retract in the extending process of the cylinder 4 so as to overcome the larger resistance when the electric coupler 1 retracts.
Example 3
Unlike embodiments 1 and 2, the auxiliary support structure further includes:
one end of the first intermediate rod 14 is coupled with the support frame 12, and the other end of the first intermediate rod 14 is coupled with the pushing rod 2;
and one end of the second intermediate rod 15 is coupled with the auxiliary support rod 3, and the other end of the second intermediate rod 15 is coupled with the first intermediate rod 14.
In the horizontal direction, the axial joint of the first intermediate lever 14 and the support frame 12 is located on the side closer to the longitudinal center line 13 of the coupler relative to the joint of the push rod 2 and the electric coupler 1. The structure can ensure that the electric coupler 1 can be in a locked stable state when being pushed out to the position.
As in embodiments 1 and 2, the drive mechanism and the auxiliary support structure are configured such that the push rod 2 is in a horizontal state when the electric coupler is pushed into position. This can be achieved by adjusting the length and mounting position of the first intermediate bar 14, the second intermediate bar 15, the auxiliary support bar 3 in the cylinder 4 and the auxiliary support structure.
Referring to the structural improvement shown in fig. 7 and 8, a first intermediate lever rotating shaft 6, a first intermediate lever 14, a second intermediate lever 15 and a second intermediate lever rotating shaft 16 which are fixed on a guide support frame 12 are added, a V-shaped lever (an auxiliary support lever 3) is composed of a first lever body 301 and a second lever body 302, the two lever bodies are rigidly connected, and the second intermediate lever rotating shaft 16 and the second intermediate lever 15 which are hinged and fixed on the guide support frame 12 are introduced, so that the hinged and fixed position of the first rotating shaft 10 of the V-shaped lever can move towards one side of the longitudinal center line 13 of the coupler. Similar to the structure in embodiment 2, the driving cylinders 4 can be selectively arranged on both sides of the first rotating shaft 10 of the "V" shaped rod, and when the first rotating shaft 10 of the "V" shaped rod is located on the side close to the electric coupler 1, the driving cylinders 4 are retracted to realize the pushing out of the electric coupler 1; when on the opposite side, the extended state of the drive cylinder 4 effects the pushing out of the electric coupler 1.
In order to realize self-locking after the electric coupler 1 is pushed out to the right position, in the horizontal direction, the plane of the joint of the first intermediate lever 14 and the support frame is closer to the plane of the joint of the first force transmission element and the driving mechanism relative to the plane of the joint of the push lever and the electric coupler. As shown in fig. 7, the driving cylinder 4 is retracted, and the push rod 2 is in a direction parallel to the longitudinal center line 13 of the coupler; the connecting shafts of the push rod 2 and the first intermediate lever 14 are located on one side far away from the longitudinal center line 13 of the coupler relative to the connecting lines of the push rod 2, the connecting shafts of the electric coupler and the first intermediate lever 14 and the connecting shafts of the support frame, which is described with reference to the attached drawings, that is, the second rotating shaft 8 of the push rod and the longitudinal center line 13 of the coupler are respectively located on two sides of the connecting line of the first rotating shaft 7 of the push rod and the rotating shaft 6 of the first intermediate lever. The angle b between the push rod 2 and the line connecting the first intermediate rod 14 to the push rod is greater than 180 °. Since the angle b is greater than 180 °, it is still 185 ° in this embodiment. When an external force pushes the electric coupler 1, the first intermediate rod 14 tends to rotate towards the opposite side relative to the longitudinal center line 13 of the coupler, the driving cylinder 4 tends to be pulled, and at the moment, the driving cylinder 4 extends to the maximum stroke position and cannot extend continuously to prevent the rotating arm from rotating towards the opposite side of the longitudinal center line 13 of the coupler, so that the electric coupler 1 is prevented from retracting, and self-locking is realized.
This modified structure has the following advantageous effects in addition to the advantageous effects of the structure in embodiment 2: after the first rotating shaft 10 of the V-shaped rod moves towards one side of the longitudinal central line 13 of the coupler, the hinging and fixing position of the driving cylinder 4 can be allowed to move towards one side of the longitudinal central line 13 of the coupler, so that the hinging and fixing position of the driving cylinder 4 is more flexible, and the driving cylinder 4 can be prevented from interfering with some parts in some projects with more coupler accessories; the compactness of the pushing mechanism is further improved; the space arrangement of each part of the pushing mechanism is allowed to be optimized, and mutual interference is avoided.
The car coupler pushing device provided by the scheme is a novel rotary arm internal rotation type electric car coupler pushing device, has the advantages of a cylinder direct pushing type pushing structure and a reverse pushing type self-locking pushing structure, and can improve the stability of coupling of the car coupler.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
