Abstract
Description
Technical Field
[0001] This utility model relates to the field of power construction technology, and in particular to a conduit threading device. Background Technology
[0002] Cable pullers, also known as fiberglass cable pullers, are excellent tools for guiding ropes through conduits. Their smooth and flexible surface allows them to easily pass through narrow passages. Cable pullers are essential for electrical installations.
[0003] Existing application CN202322375800.9 discloses a pipe threading device, including a support plate, support legs, and movable wheels. The support legs are installed below the support plate, and the movable wheels are installed below the support legs. It also includes a threading mechanism for pulling the wire through the pipe, which is installed above the support plate. This prior art, by setting up a threading mechanism, stops the forward and reverse motor when the fixed seat reaches the other end of the pipe. One end of the wire is inserted into the fixed seat, and a knob is turned. The knob drives a threaded rod to rotate, which in turn moves a pressure plate and a movable block. The pressure plate moves to compress and fix the wire, effectively reducing the probability of the wire falling off during threading. However, this prior art cannot change the direction at bends inside the pipe, leading to tangled cables during threading and making it difficult to continue threading, thus delaying the work process. Furthermore, the prior art cannot estimate the distance inside the pipe, making accurate positioning impossible and resulting in low construction efficiency. Utility Model Content
