Adjustable distraction dual-purpose machine

Abstract

The invention provides an adjustable stretching dual-purpose machine, and belongs to the technical field of power grid erecting tools. An adjustable stretching and retracting dual-purpose machine comprises a frame, a power assembly, a winding drum, a controller, a hydraulic system, a hoisting mechanism and a guide support. The winding drum and the slidable hoisting mechanism are arranged on the frame, and the guide bracket with the angle sensor is arranged between the hoisting mechanism and the winding drum, so that when a cable is wound on the winding drum, the guide bracket and the hoisting mechanism and is subjected to traction recovery or tension pay-off, the cable can be wound on the guide bracket and the hoisting mechanism; the inclination state of the cable between the winding drum and the hoisting mechanism is detected through the angle sensor, the position of the hoisting mechanism is adjusted through sliding of the hoisting mechanism, the cable is straightened, the situation that the cable is subjected to excessive lateral tension on the winding drum, the guide support and the hoisting mechanism is avoided, and the cable is prevented from being damaged. Therefore, the slipping risk of the cable on the winding drum, the guide support and the hoisting mechanism in the axial direction of the winding drum is reduced, the probability that the cable is prone to abrasion during stretching work is reduced, and safety is improved.

Description

technical field [0001] The invention relates to the technical field of power grid erection tools, in particular to an adjustable tension dual-purpose machine. Background technique [0002] The dual-purpose stretching machine can not only realize the pulling and recovery of the cable, but also realize the tension and pay-off of the cable, and has the functions of both the existing pulling machine and the tensioning machine. When it is being pulled and recovered, the main variable pump in the hydraulic system inside it works to output hydraulic oil, drives the quantitative main hydraulic motor with brake to operate, and drives the reel to rotate, and pulls the cable through the reel to move, so as to realize the control of the cable. The swash plate swing angle of the main variable pump in the hydraulic system is zero degrees when it is tensioned and paid off. At this time, the main variable pump has no hydraulic oil output, and the quantitative main hydraulic motor acts as a ...

AI Technical Summary

Problems solved by technology

[0003] However, in actual use, since the reel has a certain width, there will be a problem of inclination when the cable is wound on the reel, and after the cable is wound on the reel, it is necessary to wind the guide pulley on the hoisting mechanism. However, since the position of the hoisting mechanism in the axial direction of the reel cannot be changed, there will be multiple oblique pull states when the cable is wound on the reel during traction recovery and tension pay-off, resulting in The cable is subject to excessive lateral tension, making the cable slippery on the reel and hoisting mechanism along the axial direction of the reel, which not only has the risk of cable wear, but also poses a greater safety hazard
