The bayonet is used for hanging the shaft of the cable reel.

Preferably, the guide shaft is a dovetail, and the guide groove is a dovetail. When the lifting frame is installed in the guide shaft, the lifting frame can only move up and down without swinging and falling off.

Preferably, wheels are arranged on the outer sides of the upright posts. After the cable coil is hoisted, the cable coil can be directly transferred through wheels of the pay-off rack.

Preferably, the lower pulley block is connected with the lifting frame through a hook at the bottom.

In use: the motor reverses, and the hoisting frame falls to the ground position through dead weight. The pay-off rack is pushed to the position of the cable reel, the motor rotates forwards, the lifting frame is lifted, and the bayonet is hung on the shaft of the cable reel, so that the cable reel is lifted.

The utility model provides a single motor traction cable pay off rack has beneficial effect once:

1. the single motor is used for traction, the condition that one side is damaged does not exist, the structure is simple, and the reliability is high;

2. the arrangement of the guide shaft and the guide groove ensures that the lifting frame can only move up and down without swinging and falling off;

Detailed Description

The technical solution of the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-4, a single motor traction cable pay-off stand comprises a bracket 1, a movable pulley assembly 2 and an n-shaped lifting frame 3.

The support 1 is a supporting structure of a cable pay-off rack, two sides of a base 11 of the support 1 are connected with upright columns 12, and cross columns 13 are connected between the upright columns 12; the front of the upright posts 12 is provided with guide grooves 121, and the guide grooves 121 on the two upright posts 12 are matched with the guide shafts 321, so that the lifting frame 3 cannot swing and dislocate. Wheels 14 are arranged on the outer side of the upright post 12. After the cable drum is suspended, it can be transferred directly by the wheels 14 of the pay-off stand.

The movable pulley assembly 2 comprises an upper pulley block 21, a lower pulley block 22 and a motor 23; the motor 23 is fixed on the base 11, the upper pulley block 21 is fixed on the front surface of the cross column 13, the lower pulley block 22 is connected with the upper pulley block 21 through a cable, and the upper pulley block 21 leads out a power cable 24 to be wound on a rotating shaft of the motor 23; the load of the motor 23 can be reduced by moving the pulley assembly 2.
