Description

Technical Field

[0001] This invention mainly relates to the field of rail transit maintenance or repair equipment technology, specifically a manual-automatic transmission device for a car lifting machine and the car lifting machine itself. Background Technology

[0002] When performing maintenance work on locomotives and rolling stock for rail transit vehicles, it is necessary to jack up the locomotive and rolling stock bodies. In existing technology, jacking machines are generally used. Jacking machines are widely used in the maintenance of locomotives and rolling stock in railway systems due to their large lifting capacity and smooth lifting.

[0003] When overhauling locomotives and rolling stock, a lifting machine is needed to elevate them to allow for the inspection of components underneath. This often requires multiple lifting machines to simultaneously execute lifting commands. After the inspection is completed, the lifting machine lowers the vehicle. Traditional rail vehicle lifting machines typically use a motor-driven screw drive to raise and lower the support frame; however, power outages are common during peak electricity usage periods, causing the lifting machine to lock at a certain height, preventing further lifting operations and creating inconvenience and safety hazards for the lifting process. Summary of the Invention

[0044] In a specific application example, the symmetrically arranged worm gear drive shafts 114 are fixedly connected by the coupling 119.

[0045] In a specific application example, the motor shaft of the bidirectional output motor 106 is fixedly connected to the first inner ring 1311 of the positive gear 131, which is used to drive the first inner ring 1311 to rotate clockwise. The first roller 1312 of the positive gear 131 is used to drive the first intermediate ring 1313 to rotate. The first intermediate ring 1313 is fixedly connected to the first transmission shaft 103, thereby realizing that the bidirectional output motor 106 drives the first transmission shaft 103 to rotate.

[0049] Working principle:

[0050] During the lifting process, the working principle of the motor drive is as follows: When the bidirectional output motor 106 is working, the motor shaft of the bidirectional output motor 106 is fixedly connected to the first inner ring 1311 of the positive gear 131, driving the first inner ring 1311 to rotate clockwise. At the same time, the first roller 1312 rolls to the left side of the groove, thereby driving the first intermediate ring 1313 to rotate clockwise. The first intermediate ring 1313 is fixedly connected to the first transmission shaft 103, thereby realizing that the bidirectional output motor 106 drives the first transmission shaft 103 to rotate.

[0051] During the lifting process, the manual transmission works as follows: when the handle 112 is rotated clockwise, the first outer ring 1315 of the positive gear 131 rotates clockwise through the worm gear transmission, and the second roller 1314 rolls to the left side of the groove, thereby driving the first intermediate ring 1313 to rotate clockwise. The first intermediate ring 1313 is fixedly connected to the first drive shaft 103, thus realizing the manual output to drive the first drive shaft 103 to rotate.

[0052] During the descent process, the working principle of the motor drive is as follows: When the bidirectional output motor 106 is working, the motor shaft of the bidirectional output motor 106 is fixedly connected to the second inner ring 1321 of the reverse gear 132, driving the second inner ring 1321 to rotate counterclockwise. At the same time, the third roller 1322 rolls to the right side of the groove, thereby driving the second intermediate ring 1323 to rotate counterclockwise. The second intermediate ring 1323 is fixedly connected to the first transmission shaft 103, thereby realizing that the bidirectional output motor 106 drives the first transmission shaft 103 to rotate.

[0053] During the descent, the manual transmission works as follows: when the handle 112 is rotated counterclockwise, the second outer ring 1325 of the reverse gear 132 rotates counterclockwise through the worm gear transmission. The fourth roller 1324 rolls to the left side of the groove, thereby driving the second intermediate ring 1323 to rotate counterclockwise. The second intermediate ring 1323 is fixedly connected to the first transmission shaft 103, thus realizing the manual output to drive the first transmission shaft 103 to rotate.
