[0002] Electric locomotives are a type of traction equipment used in rail vehicle transportation. They are powered by traction motors that drive the wheels to rotate. The friction between the wheels and the rail surface allows the locomotive to run on the track. In this mode of operation, the traction force is limited not only by the power of the traction motor (or internal combustion engine) but also by the friction between the wheels and the rail surface. There are limitations on the gradient that locomotives can travel on. The gradient of the transport track is generally 3‰, and the local gradient cannot exceed 30‰. According to their structure, they are classified into overhead wire electric locomotives and battery-powered electric locomotives.

[0003] The locomotive and the transport car are connected by a connecting structure to facilitate the locomotive to pull the car. The height of the connecting parts on different types and sizes of transport cars differs from that on the locomotive, which can lead to inconvenience or even failure to connect.

The handle 4 is fixedly disposed on the outer peripheral wall of the rod 3, and the side wall of the U-shaped locking block 2 has a sliding groove 23, which communicates with the telescopic groove 22. The handle 4 slides in cooperation with the sliding groove 23.

[0027] The adjustment mechanism includes an adjustment seat 5, a rotary motor 51, and a lead screw 52. The adjustment seat 5 is fixedly installed on the side wall of the locomotive body 1. A lifting groove 53 is provided on the adjustment seat 5. The lead screw 52 is rotatably installed in the lifting groove 53. The rotary motor 51 is installed on the top of the adjustment seat 5, and its output end is connected to the lead screw 52. A slider 24 is provided on the side of the U-shaped block 2 away from the slot 21. The slider 24 is installed on the lead screw 52.

[0028] The rotary motor 51 is fixed on the top of the adjusting seat 5. After the rotary motor 51 is started, its output shaft drives the lead screw 52 to rotate in the lifting groove 53 of the adjusting seat 5. The U-shaped locking block 2 is mounted on the lead screw 52 through the slider 24. The rotation of the lead screw 52 is converted into the linear motion of the slider 24, thereby driving the U-shaped locking block 2 and the entire locking mechanism to rise or fall.

[0029] A guide rod 6 is fixedly installed inside the telescopic groove 22, and a guide hole 32 is provided inside the insertion rod 3. The guide rod 6 is inserted into the guide hole 32. The size of the guide rod 6 is adapted to the guide hole 32. The first spring 31 is sleeved on the guide rod 6, and one end of the first spring 31 is connected to the insertion rod 3, and the other end is connected to the side wall of the telescopic groove 22. By setting the cooperation between the guide rod 6 and the insertion rod 3, a guiding function is provided for the movement of the insertion rod 3. The setting of the first spring 31 allows the insertion rod 3 to automatically extend into the slot 21 in the unlocked state to complete the locking. The spring sleeved on the insertion rod 3 improves the stability of the overall device.

[0030] The end of the slide groove 23 is provided with a groove 25, and the bottom of the handle 4 is provided with a locking component for locking the retracted insertion rod 3. The locking component includes a protrusion 7 and a second spring 71. The protrusion 7 is telescopically provided at the bottom of the handle 4, and the second spring 71 is disposed between the handle 4 and the protrusion 7 and connected to both. The bottom of the handle 4 is provided with a locking groove 41. One end of the spring is connected to the top of the locking groove 41, and the other end is connected to the protrusion 7. The size of the protrusion 7 is adapted to the locking groove 41. The size of the protrusion 7 is adapted to the groove 25, and the protrusion 7 extends to the outside of the U-shaped locking block 2.

[0031] When it is necessary to release the transport compartment, the handle 4 can be pulled to move the insert rod 3 away from the slot 21, thereby releasing the lock on the transport compartment. After release, the protrusion 7, under the elastic force of the second spring 71, extends into the groove 25 to lock the insert rod 3. Since the protrusion 7 extends to the outside of the U-shaped block 2, it is convenient for the staff to manually press the protrusion 7 to disengage it from the groove 25. Then, under the elastic force of the first spring 31, it extends into the slot 21 to complete the lock, which facilitates disassembly and the next installation.

[0032] According to one embodiment of the present invention, the slider 24 is adapted to the size of the lifting groove 53.

[0033] The working principle of this invention is as follows: When the height of the locomotive needs to be adjusted, the rotary motor 51 in the adjustment mechanism is activated. The rotary motor 51 drives the lead screw 52 to rotate. Since the U-shaped locking block 2 is mounted on the lead screw 52 via the slider 24, and the size of the slider 24 is adapted to the lifting groove 53, the slider 24 is restricted to moving up and down along the lifting groove 53. When the lead screw 52 rotates, the slider 24 moves up and down in the lifting groove 53 along the thread direction of the lead screw 52, ​​thereby driving the connected locking mechanism to rise or fall as a whole, thus realizing the adjustment of the locomotive height.

[0034] After adjusting the locomotive height, the transport car is secured using a latching mechanism. The connecting end of the transport car to be secured is placed in the slot 21 of the U-shaped latch 2, and the connecting end is secured by the insert rod 3, with the connecting end engaging with the slot 21. Once the transport car is fully in place, the insert rod 3, under the elastic force of the first spring 31, springs back towards the slot 21, inserting into the gap between the connecting end of the transport car and the slot 21, thus firmly securing the transport car and preventing it from shaking or falling during locomotive transport. To release the transport car, the handle 4 is pulled, moving the insert rod 3 away from the slot 21 to release the lock. After release, the protrusion 7, under the elastic force of the second spring 71, extends into the groove 25, locking the insert rod 3, facilitating disassembly and subsequent installation. The handle 4 slides smoothly into the slide groove 23, ensuring that the insert rod 3 moves smoothly when the handle 4 is pulled.
