The geared motor 6 is fixedly installed on the top of one side of the mounting housing 5. The upper bevel gears 14 mesh with the lower bevel gears 12 to play a transmission role. When the drive shaft 13 is rotated, it can drive the threaded rods 8 to rotate through the bevel gears, thereby driving the lifting cylinder 9 to move vertically, so as to realize the rise and fall of the roller 10.

[0020] Reference Figure 2 The output end of the geared motor 6 is fixedly connected to one end of the transmission shaft 13. The geared motor 6 can automatically drive the transmission shaft 13 to rotate, which is more convenient.

[0021] Reference Figure 1 Several reinforcing ribs 22 are fixedly connected at the connection between the hydraulic cylinder 2 and the base 1, which can improve the structural strength of the hydraulic cylinder 2 installation and prevent it from tipping over.

[0026] Working principle: The locomotive is connected to the tie rod 4 of the top-recovery equipment via a lifting device. The hydraulic cylinder 2 is activated to extend the top plate 3, lifting the locomotive. Combined with an external lateral movement device, this achieves the repositioning and straightening of the locomotive after derailment. The reduction motors 6 mounted on the housings 5 ​​on both sides of the top-recovery equipment are activated, driving the upper bevel gears 14 on both sides of the drive shaft 13 to rotate. This simultaneously drives the two threaded rods 8, which are fitted with lower bevel gears 12, to rotate. Under the constraint of the crossbar 11, the two lifting cylinders 9 can move vertically, thereby driving the rollers 1... The downward movement of the roller 10 supports the equipment, allowing it to be easily pushed and slid along the top-recovery rescue equipment. This facilitates movement, improves rescue efficiency, and ensures the stability of the equipment by retracting the roller 10 during operation. When performing top-recovery rescue on a locomotive, the locking block 19 at the connecting seat 15 can be pressed to retract it into the groove 17, thus unlocking the mechanism. The support rod 16 can be rotated downwards so that its end contacts the ground. Then, the locking block 19 will pop out under the action of the spring 18 and engage with the corresponding latch 20 to lock the position of the support rod 16, thereby improving the anti-tilt effect and ensuring the stability of the top-recovery rescue equipment during operation.
