Fully-automatic tractor used for small cables

Abstract

The invention discloses a fully-automatic tractor used for small cables. The fully-automatic tractor used for the small cables comprises a machine frame, the machine frame is provided with an electric drive mechanism, a transmission mechanism and three sets of conveying mechanisms, and the electric drive mechanism is connected with the conveying mechanisms through the transmission mechanism. Each conveying mechanism comprises an upper pressing wheel, a lower pressing wheel, an upper rotary shaft and a lower rotary shaft, wherein the upper rotary shaft and the lower rotary shaft are arranged on the machine frame in a pivoted mode; the upper pressing wheel and the lower pressing wheel are installed on one side of the machine frame through the upper rotary shaft and the lower rotary shaft respectively; the upper pressing wheel and the lower pressing wheel are spaced by a certain interval and are opposite in rotation direction; the outer periphery of the upper pressing wheel and the outer periphery of the lower pressing wheel are sleeved with soft annular rings; the outer walls of the soft annular rings are provided with grooves for limiting the cables. The fully-automatic tractor used for the small cables lowers the labor cost, relieves labor intensity, shortens the construction period, improves the construction efficiency and meets the requirements for safe use and continuous construction.

Description

technical field [0001] The invention belongs to the technical field of cable laying, in particular to a fully automatic pulling machine for small cables. Background technique [0002] When laying optical (electrical) cables or other cables in communication ducts, it is often necessary to lay the cables with a pipe threader. Pipe piercers can drive cables through narrow underground pipes. Therefore, pipe piercers have become an essential tool for the construction of telecommunications, electric power and communications units. [0003] In the prior art, when the cable is threaded through the pipe, the pipe threader adopts the method of manual cooperation. Many people first pass the special plastic rod from one end of the pipe to the other end, and then pull the cable back after fixing the cable. through the pipe. This approach has many limitations, mainly the following: [0004] 1. Due to the high labor wages in the current market, the use of manpower for cable laying will ...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the high labor wages in the current market, the use of manpower for cable laying will inevitably incur a lot of expenses, resulting in increased construction costs;

[0005] 2. When laying cables at the construction site, due to the harsh environment of most construction sites, the safety of construction personnel cannot be guaranteed, which increases potential safety hazards;

[0006] 3. Using traditional methods to lay power cables manually will directly affect the construction progress of the entire site. The construction efficiency is low and the construction period is very long. Moreover, for the owner's external cable construction period is tight and the front line is long, human laying is far from enough. Continuous Construction Requirements
