Problems solved by technology

However, because the use of the cable take-up and pay-off machine is greatly affected by the site, it is often manually dragged to perform the pay-off work
Due to many unexpected factors in the manual pay-off work, it is very easy for the cable to slip in reverse, which brings great safety hazards and easily leads to safety accidents

Embodiment Construction

[0025] Below in conjunction with accompanying drawing and embodiment the present invention is described in detail:

[0026] Such as Figure 1 to Figure 9 As shown, the new pay-off anti-reverse device of the present invention includes a base, and the base is sequentially provided with a first guide seat 1, a first anti-reverse structure 2, The non-return trigger structure 3 and the second guide seat, the first guide seat 1 and the second guide seat are all rotatably provided with guide rollers 4 matching the outer diameter of the cable, the first guide seat 1 and the second guide seat The structure is the same, and the guide roller 4 guides the cable to run in a straight line to ensure that the cable passes through the first non-return structure 2 and the non-return trigger structure 3 in a correct posture.

[0027] The existing anti-reverse device for paying off wires partly uses the eccentric balance wheel 34 to realize the anti-reverse action, but because the contact area b...

Abstract

The invention discloses a novel pay-off non-return device which comprises a base, a first guide seat, a first non-return structure, a non-return trigger structure and a second guide seat are arranged in the base, guide rollers matched with the outer diameter of a cable are rotationally arranged in the first guide seat and the second guide seat, and the first non-return structure comprises a first non-return structure shell. A cable containing cavity is formed in the first non-return structure shell, the left side face and the right side face of the rear portion of the cable containing cavity shrink inwards to form inclined faces, cable clamping wedge blocks are arranged on the left side and the right side in the cable containing cavity in a sliding mode respectively, and cable clamping wedge block limiting structures are arranged on the outer sides of the cable clamping wedge blocks. A clamping roller rotating in one direction is arranged in the non-return triggering structure in an up-down rotating mode. The cable pay-off device can effectively prevent a cable from reversely slipping in the pay-off work, and potential safety hazards are completely eradicated.

Description

technical field [0001] The invention relates to the field of power line installation, in particular to a novel anti-return device for paying out wires. Background technique [0002] At present, in electric power construction operations, the cable take-up and pay-off machine is a commonly used take-up and take-off equipment, which is used to cooperate with the take-up and take-off work during cable erection. However, because the use of the cable take-up and pay-off machine is greatly affected by the site, it is often manually dragged to perform the pay-off work. Due to many unexpected factors in the manual pay-off work, it is very easy for the cable to slip in reverse, which brings great potential safety hazards and easily leads to safety accidents. Contents of the invention [0003] The purpose of the present invention is to provide a new type of anti-reverse device for paying out wires, which can effectively prevent the phenomenon of reverse slippage of cables during the...
