Tensile machine for power dispatching grid construction

Abstract

The invention discloses a tensile machine for power dispatching grid construction. The tensile machine comprises a base, universal wheels, a left extension board, bolts, a drilling bit, a handle, a right extension board, a lifting rod, a sucker, a locking shaft, an upright column, a retractable device, a guide wire device, a vertical rod, a first pulley and so on. The tensile machine has a reasonable, simple structure, has low production cost, is convenient to install, controls the traction force effectively under drive of a drive motor and a coupler; the base is fixed by the sucker and the drilling bit, so that the whole device swings with a smaller amplitude; a cable passes through an arc groove, then passes through between the first pulley and the second pulley and passes through an arcbase in sequence, the height of the arc groove is adjustable, a distance between the first pulley and the second pulley is adjustable, the arc base is elastic, so that the cable is not clamped or does not swing; and the tensile machine has high stability, can control the traction speed of the cable effectively, and is highly safe, thereby guaranteeing the construction efficiency effectively.

Description

technical field [0001] The invention relates to the field of power grids, in particular to a stretcher for construction of power dispatching power grids. Background technique [0002] At present, the stringing construction is one of the key processes in the construction of transmission lines, and the tension machine is the key equipment for the tension stringing construction. Because the motorized reamer lacks the function of constant tension and constant speed, the traction field and the tension field cannot operate at the same speed under manual control, so it is difficult to control the rope slack during the deployment process. At present, when the stretching machine on the market is pulling the cable, it is difficult to control the traction force, the swing range is large, the cable is stuck or cycloidal, etc., the stability is poor, the pulling speed of the cable is difficult to control, and the safety performance is low. , seriously affecting the construction efficien...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a tensioner for power dispatching power grid construction in order to solve the above problems, which solves the problem that the tensioner on the market is difficult to control the traction force when pulling the cable, the swing range is large, and the cable will be damaged. Stuck or cycloid phenomenon, poor stability, difficult to control the pulling speed of the cable, low safety performance, seriously affecting the construction efficiency
