Threading equipment and threading method therefor

Abstract

Disclosed are threading equipment and a threading method therefor. The threading equipment comprises an air suction apparatus, a wire drawing apparatus and a motor, wherein the air suction apparatus is connected to one end of a wire pipe for performing an air suction operation to the interior of the wire pipe and providing wire conveying power for a first lead; the wire drawing apparatus is used for winding a second lead and performing a wire drawing operation, wherein the flexibility of the second lead is higher than that of the first lead; and the motor is connected with the wire drawing apparatus and used for providing wire drawing power for the wire drawing apparatus. By virtue of the threading equipment and the threading method therefor, threading efficiency can be improved.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a threading device and a threading method thereof. Background technique [0002] In the construction of modern construction projects, electrical conduits are generally pre-embedded in walls and floors in the form of concealed laying. After the construction of the main structure is completed, the wiring of electrical conduits begins. The existing wiring method includes a threading step and a wire drawing step. After the lead wire is fed into the wire tube, it is docked with the wire, and then the lead wire is pulled back so that the wire is installed in the wire tube. The traditional wiring method is that the electrician manually feeds the lead wire into the wiring duct. This method is inefficient and time-consuming, and when encountering a wire duct with many turns and a long distance, the wire feeding process is very difficult, and it is often necessary to The wire tube is...

AI Technical Summary

Problems solved by technology

The traditional wiring method is that the electrician manually feeds the lead wire into the wiring duct. This method is inefficient and time-consuming, and when encountering a wire duct with many turns and a long distance, the wire feeding process is very difficult, and it is often necessary to The wire tube is slotted out and re-arranged; although the threading machine is used to imitate the manual wire take-up method, the effect of labor-saving can be achieved to a certain extent when pulling the wire, but there is still the problem of difficulty in threading

[0003] In the prior art, a group of wheels are used to squeeze the lead wire, and the lead wire is sent into the wire tube through friction as power. This wire feeding method is far away from the wire feeding port and has the problem of more power loss.

Moreover, the ability of the lead wire to transmit thrust is poor, and it mainly relies on the elasticity of the rope to advance. When the number of turns is large, the threading process is more difficult and the efficiency is lower.
