Automatic pay-off device used for communication pipeline laying

Abstract

The invention discloses an automatic pay-off device used for communication pipeline laying. The automatic pay-off device comprises a walking wheel, a gate mechanism, two one-way clamping mechanisms and supports. A cavity used for containing a communication wiring harness is arranged in the walking wheel. A gap used for allowing the communication wiring harness to enter the cavity is formed on theouter edge of the walking wheel. The gate mechanism is used for being arranged on the gap of the walking wheel in an opening and closing manner. Each one-way clamping mechanism comprises a rotating disc assembly, an elastic clamping assembly and a pulling assembly. The rotating disc assemblies are fixedly arranged on the walking wheel, multiple grooves are formed in each rotating disc assembly, the elastic clamping assemblies are mounted on the supports, and inserting blocks used for being inserted into the grooves are fixedly arranged on the elastic clamping assemblies. Even though the automatic pay-off device used for communication pipeline laying meets with a steep road surface or a high step, the automatic pay-off device used for communication pipeline laying can move, a communicationpipeline can move without being dismounted down from the wheel, and workloads are reduced.

Description

technical field [0001] The invention relates to the technical field of communication pipelines, in particular to an automatic pay-off device for laying communication pipelines. Background technique [0002] In the laying out of communication networks, in the process of laying out local area networks, cables are used to transmit telephone calls, telegrams, fax documents, TV and radio programs, data and other electrical signals. One of the difficulties in construction is the laying of pipelines and cables, especially in the case of going up and down stairs or stairs. The laying is inconvenient and inefficient, which seriously affects the construction progress and time limit. [0003] Chinese patent application No. 201310157892.1 in the existing design discloses the construction method of the pipeline construction pay-off device for laying sub-pipes. The pay-off device simplifies the construction steps and shortens the construction time, and is suitable for sub-pipe coils of va...

AI Technical Summary

Problems solved by technology

[0006] Although these two solutions effectively solve the problem of pipeline support and pipeline construction safety, workers need to carry the pipeline during the construction process, and it is often difficult to move when encountering steep or high steps on the ground

[0007] Although these two schemes can solve the problem of pipeline placement, because the communication pipeline is often wound on the wheel, adopting these two schemes needs to unload the communication pipeline from the wheel, and put it on the pay-off device, which increases the worker's workload. workload
