The main shafts are respectively rotatably sleeved on both sides of the vertical plates. Two groups of the retracting shafts are provided, and the retracting shafts are integrally provided with the main shafts on both sides respectively. The roller frame is sleeved between the retracting shafts on both sides; the retracting shaft and the main shaft are connected by a spring column, and the inner side of the spring column is sleeved with the roller frame through a convex shaft;

[0008] A guide rail is arranged along the length direction of the C-shaped frame. The guide ring is slidably sleeved in the guide rail. An extended positioning wing protrudes outward from the guide ring. The position of the guide ring on the C-shaped frame is adjusted through the limit cooperation between the extended positioning wing and the guide rail.

[0009] Preferably, a transmission belt is sleeved on one of the main shafts, and a reduction motor is installed on the top of the same side of the machine frame. The output end of the reduction motor is sleeved with the other end of the transmission belt.

[0010] Preferably, a positioning bolt for locking the U-shaped frame and the vertical plate is provided on the vertical plate through threaded connection.

[0011] Preferably, a collar is provided in the middle of the guide ring through a bearing connection.

[0012] Preferably, a plurality of pin shaft holes II are provided on the U-shaped frame along the length direction of the guide rail.

[0013] Preferably, a pin shaft hole I is correspondingly provided on the extended positioning wing to cooperate with the pin shaft hole II.

[0014] Preferably, universal wheels for movement are provided at the bottom of the machine frame.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. In the present utility model, through the arranged telescopic shaft structure, the easy connection of the roller frame can be completed, and the transportation pressure during equipment transportation can be reduced.

[0017] 2. In the present utility model, through the setting of the guide ring, different requirements during winding and unwinding can be met, playing a supporting role and avoiding large friction between the steel wire rope and the elevator entrance.

[0018] 3. In the present utility model, the guide ring can slide on the U-shaped frame to adjust the horizontal position, which is convenient for freely adjusting the position of the wire inlet and outlet during the winding and unwinding process, with high freedom.
