A control device for inner space of wire pipe

Abstract

The purpose of the present invention is to solve the existing problem that it is difficult to control the inner space of the wire pipe, and discloses a control device for the inner space of the wire pipe, which includes a chassis and a bottom plate, and fastening screws are symmetrically installed on the bottom plate. A bracket is welded on the upper surface of the bottom plate, a holding plate is installed on the top of the support, a first rotating shaft is connected between the holding plate and the support, a rocking handle is set on the front end of the surface of the first rotating shaft, and the space between the chassis and the holding plate is A drawstring is connected, a holding groove is opened on the chassis, a connecting frame is welded symmetrically on the side of the chassis, and a guide wheel is sleeved inside the connecting frame. The present invention rationally utilizes the driving of the first grinding disc and the second grinding disc, and uses the first grinding disc and the second grinding disc to grind the inner wall of the wire pipe, thereby thinning the pipe wall and allowing the wire pipe to penetrate more Wires to achieve control of the inner space of the wire tube.

Description

technical field [0001] The invention relates to the field of pipeline machinery, in particular to an internal space control device of a line pipe. Background technique [0002] The full name of the threading pipe is "insulated electrical casing for construction", which is a kind of white rigid PVC pipe, which is anti-corrosion, anti-leakage, and used for threading. Divided into plastic threading pipe, stainless steel threading pipe, carbon steel threading pipe. It is used in normal indoor environment and in places with high temperature, dust, vibration and fire hazard. Can also be used in wet places. It should not be used in places with extreme humidity, acid, alkali, salt corrosion and explosion hazard. [0003] The diameter of the line pipe is different, and it is divided into different specifications of the line pipe. The space inside the line pipe is fixed. If the line pipe cannot be filled with more wires, it needs to be replaced with a larger line pipe for dressing....

AI Technical Summary

Problems solved by technology

[0003] The diameter of the wire tube is different, and it is divided into different specifications of the wire tube. The space inside the wire tube is certain. If the wire tube cannot be filled with more wires, it needs to be replaced with a larger wire tube. It will cause waste to the line tube, it is not easy to fill more wires without changing the line tube, and it is not easy to control the space capacity inside the line tube. It takes a long time to search for the line pipes, and it is necessary to pull out all the lines in the line pipes before replacing them. The operation is cumbersome. Therefore, it is urgent to design a control device for the inner space of the line pipes to solve the shortcomings of the existing technology
