How to Improve the Quality of Cable Spool?

February 02, 2023

The plastic wire reel comprises a take-up wheel body, a ratchet wheel, a sector gear and a pullback spring, wherein the sector gear is composed of a circular surface part and a tooth shape part, the ratchet wheel is rotatable fixed on the take-up wheel body and its spring fixed end is separately connected with one end of the two pull back springs. In the take-up state, the two pull back springs are symmetrically arranged with respect to the spring fixed end of the ratchet wheel.

During the construction process, the plastic wire reel laying cannot be fully mechanized, and the manual work is heavy. Moreover, most cables are VV35mm2, VV50mm2 or even VV70mm2. This large-diameter electric plastic wire reel is coiled on a disc when leaving the factory. It cannot be moved by manpower. It can only be manually removed on the ground and pulled through the pipe by manpower. In order to keep consistent with the pace of wire head traction, a certain length of plastic wire reel should be removed from the wire reel in advance before the start of traction work, and the setting out should be monitored by several construction personnel.

1. Cable reel statistical quality control stage.

The characteristic of this stage is to use the statistical principle to carry out quality control between production processes, prevent unqualified products and inspect the quality of products. In terms of method, the responsible person is also transferred from full-time inspectors to professional quality control engineers and technicians.

2. Wire coil quality inspection stage.

The control box shall be strictly inspected to ensure the quality of products transferred to the next process and delivered from the factory. The characteristic of full-time inspection is "separation of three powers", that is, someone sets standards; someone is responsible for manufacturing; There are full-time inspectors to inspect the quality of products. In essence, this practice is to sort out waste products and grade them. Although this has certain effect on ensuring the factory quality

3. Fixing method of wire reel

The pay-off plate is made of steel plate, reinforcement and channel steel (the size of blanking is determined by itself). Its structural design is as follows: the channel steel is symmetrically placed into a circle as the bottom fixed support foot, the two steel plates are used to make the rotating plate, the upper part is the rotating plate surface, the lower part is the fixed plate surface, the fixed plate surface is welded on the channel steel surface, and then a steel bar is used to make the center bar, and the thread at one end can be screwed into the center bearing screw hole of the rotating plate, One end is made into a buckle to facilitate the lifting of mechanical equipment.

Summary

The equipment has simple structure, reasonable design and convenient handling, which not only solves many problems mentioned above, but also realizes semi-mechanized operation of paying-off operation. More importantly, because the pay-off reel is small and flexible, it can be placed near the laying pipe orifice, and the traction wire head is directly into the pipe.
