[0041] The movable locking mechanism 2 includes a limiting member 21, an elastic telescopic member 22 and an unlocking device 23;

[0042] The limiting member 21 is telescopically arranged in the first connecting device 1 through the elastic and telescopic member 22, and when the elastic and telescopic member 22 is in the initial state, the limiting member 21 is horizontally arranged in the first groove 111, and is used to limit the second connecting device 3 during connecting to prevent it from being separated from the first groove 111;

[0043] The unlocking device 23 is connected to the limiting member 21 or the elastic telescopic member 22;

[0044] If the first coupling device 1 is arranged on the rail tractor, the second coupling device 3 is arranged on the process bogie;

[0045] If the first coupling device 1 is arranged on the process bogie, the second coupling device 3 is arranged on the rail tractor;

[0046] The second connecting device 3 can be stuck in the first groove 111 through the limiting member 21 .

[0047] Reference Figures 1 to 4 In one embodiment, the first connecting device 1 includes a fixed base 11 and a guide member 12; the fixed base 11 is provided with the first groove 111; the guide member 12 is provided with a guide groove 121; the guide member 12 is provided on the fixed base 11, and the guide groove 121 is located above the first groove 111, and the guide groove 121 and the first groove 111 are connected vertically.

[0048] Reference Figures 1 to 4 In one embodiment, the first groove 111 is a "U"-shaped groove.

[0049] Reference Figures 1 to 4 In one embodiment, the guide groove 121 is a “Y”-shaped groove.

[0050] Reference Figures 1 to 4 In one embodiment, the guide member 12 is a flat plate; the guide member 12 is fixed to the fixed base 11 by a bolt assembly 122. The guide member 12 with a "Y"-shaped groove facilitates automatic coupling when the rail tractor and the process bogie are not on the same axial center line. The guide member 12 with a "Y"-shaped groove increases the coupling range of the rail tractor and the process bogie, and can still achieve automatic coupling of the two when the axial docking coupling deviation between the rail tractor and the process bogie is large; this design improves the adaptability of the "push-pull automatic coupling device" and can meet all road conditions in the vehicle depot.

[0051] Reference Figures 1 to 4 In one embodiment, the first end of the elastic telescopic member 22 is fixedly connected to one side of the fixed base 11, and the second end of the elastic telescopic member 22 is connected to the first end of the limiting member 21. When the elastic telescopic member 22 is in the initial state, the second end of the limiting member 21 is horizontally arranged in the first groove 111.

[0052] Reference Figures 1 to 4 In one embodiment, the limiting member 21 is a cube-shaped bar.

[0053] Reference Figures 1 to 6In one embodiment, the second end of the limit member 21 is provided with a slope 211 on the side facing the outside of the first groove; the second end of the limit member 21 is provided with a plane 212 on the side facing the inside of the first groove; the slope 211 is conducive to the locking pin to push the limit member open and enter the position inside the first groove; the plane 212 can increase the force-bearing area, which is convenient for the limit member 21 to limit the locking pin 31 in the first groove 111 when connected. Correspondingly, the locking pin 31 is used as a round shaft member, which is provided with a vertical plane 311 of the shaft body that is in contact with the plane 212. When the rail tractor is coupled with the process bogie through the "a push-pull automatic coupling device" of the utility model, during the coupling process, the guide groove 121 of the guide member 12 of the first coupling device 1 can easily guide the locking pin 31 of the second coupling device 3 into the first groove 111. During the introduction, the locking pin 31 causes the limiting member 21 with the inclined surface 211 to compress the elastic telescopic member 22 to produce a lateral shortening movement, and then the locking pin 31 slides into the first groove 111; after the locking pin 31 passes over the limiting member 21, the elastic telescopic member 22 returns to its initial state, drives the limiting member 21 to reset, and stably restricts the locking pin 31 in the first groove 111, thereby realizing automatic coupling; when the rail tractor needs to be uncoupled from the process bogie, the unlocking device 23 is manually adjusted to release the restriction of the limiting member 21 on the locking pin 31, so that the locking pin 31 can freely break away from the first groove 111 and leave. The utility model can realize automatic coupling and manual unlocking, and has the advantages of large automatic coupling range and short unlocking stroke; the guide member 12 with the guide groove 121 enables the utility model to realize automatic coupling even when the axial coupling deviation between the rail tractor and the process bogie is large. The utility model is cleverly designed, greatly improves work efficiency, and is conducive to improving the labor intensity of employees.

[0055] Reference Figure 1 In this embodiment, one end of the pulling member 231 is threadedly connected to the first end of the limiting member 21 .

[0056] In one embodiment, the pulling member 231 is a steel wire rope.

[0057] Reference Figure 1 and Figure 4 In one embodiment, the unlocking device 23 further includes a handle 232 , and the handle 232 is connected to the other end of the pulling member 231 .

[0058] Reference Figure 1 and Figure 4In one embodiment, the second coupling device 3 includes a locking pin 31; when the rail tractor is coupled to the process bogie, the locking pin 31 can push away the limiting member 21 and then be restricted in the first groove 111 by the limiting member 21.

[0059] Reference Figure 1 and Figure 4 In one embodiment, the locking pin 31 is a round shaft.

[0060] Reference Figures 1 to 6 In one embodiment, the second hanging device 3 further includes a ring seat 32;

[0061] If the first coupling device 1 is arranged on a rail tractor, the ring seat 32 of the second coupling device 3 is arranged on a process bogie, and the locking pin 31 is vertically arranged on the ring seat 32;

[0062] If the first coupling device 1 is arranged on a process bogie, the ring seat 32 of the second coupling device 3 is arranged on a rail tractor, and the locking pin 31 is vertically arranged on the ring seat 32 .

The constant force spring is arranged in the fixed base 11 of the first coupling device 1 and is connected to the first end of the limiter 21. When the constant force spring is in the initial state, the second end of the limiter 21 is horizontally arranged in the first groove 111. When the rail tractor and the process bogie are coupled through the "a push-pull automatic coupling device" of the utility model, the lock pin 31 is introduced into the first groove 111, and the limiter 21 limits the lock pin 31 in the first groove 111 by relying on the constant force spring, wherein the constant force spring can ensure that the limiter 21 always keeps the limit on the lock pin 31 during the moving process. The unlocking device 23 is used to perform the unlocking action after the vehicle is moved. Specifically, the handle 232 is turned, and the puller 231 of the unlocking device 23 drives the limiter 21 to compress the constant force spring to realize the lateral shortening movement, so that the limiter 21 no longer limits the lock pin 31, thereby, the lock pin 31 can freely break away from the first groove 111 to achieve unlocking.

[0064] In one embodiment, the first coupling device 1 is arranged on the rail tractor, and the second coupling device 3 is arranged on the process bogie. The operation of the utility model comprises the following steps:

[0065] S1. Check the first connecting device 1 and the second connecting device 3 to ensure that their respective matching fasteners are not loose or deformed.

[0066] S2. Move the rail tractor to the front of the process bogie to be coupled, and operate the rail tractor to move forward slowly until the limit member 21 locks the locking pin 31 on the process bogie in the first groove 111.

[0067] S3. When in use, operate the rail tractor to move smoothly; during the movement, pay attention to the state of the "push-pull automatic coupling device" of the utility model.

[0068] S4. After the subway train body is moved to the destination, the handle 232 of the unlocking device 23 is turned to compress the constant force spring of the limit member 21 and retract it laterally, thereby releasing the restriction of the limit member 21 on the lock pin 31, and then the rail tractor is operated to move backward until it leaves the process bogie.

[0069] S5. Drive the rail tractor away from the work site and park it securely.
