One group of driven steering rollers 79 are respectively arranged on the right sides of the active steering rollers 77. One group of driven fixing seats 78 are respectively arranged at the bottoms of the driven steering rollers 79. The output end of the lifting motor 73 controls the operation of the rotating bevel gear by using a rotating shaft. The rotating bevel gear controls the rotation of one group of connecting bevel gears 74 at the front and rear ends respectively. The connecting bevel gears 74 respectively drive the corresponding rotating rods 75 to control the synchronous operation of the corresponding active steering rollers 77. Due to the pulling force of the lifting chain 4, the active steering rollers 77 drive the driven steering rollers 79 to rotate together, and can simultaneously control the synchronous lifting of the four groups of lifting chains 4, stably and coordinately controlling the lifting operation of the cargo car 2. The hoist top seat 7 installs the active steering rollers 77 through the active fixing seats 76, and installs the driven steering rollers 79 through the driven fixing seats 78 to ensure the safe use of the lifting device.

[0026] On the active steering rollers 77, two sets of first rotating gears are provided in parallel respectively.

The cargo car 2 establishes a fixed connection with the four sets of lifting chains 4 through the four connecting pins 24, so that the lifting device can act on the cargo car 2 to realize the lifting control.

[0028] Refer to Figure 2 and Figure 4 , at the top of the right-end panel in the inner cavity of the hoist frame 1, a ranging displacement sensor 8 is provided.

The two sets of vertical sliding seats limit the moving direction of the chain counterweight fixing seat 9. During the process of the cargo car 2 moving upward under the action of the lifting motor 73, the lifting chain 4 gradually moves upward. Then, affected by gravity, the chain counterweight fixing seat 9 drives the end of the lifting chain 4 that is not connected to the cargo car 2 to gradually move downward. During the process of the cargo car 2 moving downward under the action of the lifting motor 73, the end of the lifting chain 4 connected to the cargo car 2 gradually moves downward. Then, affected by the pulling force of the lifting chain 4, the chain counterweight fixing seat 9 gradually moves upward in the vertical sliding seat.
