Cable tension buffer device for engineering machinery

Abstract

The invention discloses a cable pulling force buffering apparatus for engineering machinery. The cable pulling force buffering apparatus comprises a power-supply cable and a power-utilization cable which are connected through a plug, wherein the power-supply cable is provided with a clamping and fixing apparatus; the clamping and fixing apparatus is in tensioning connection with power-utilization equipment through an elastic connecting line; and the power-utilization cable is connected with power-utilization equipment in a tension-free manner. According to the cable pulling force buffering apparatus provided by the invention, the cable is fixedly connected through the clamping and fixing apparatus; the clamping and fixing apparatus is in tensioning connection with power-utilization equipment through the elastic connecting line to be fixed, so that the problem existing in the safe connection of the cable is solved; meanwhile, for realizing safer and more convenient connection and maintenance of the cable, a cable connecting supporting column is arranged on the power-utilization equipment, and a rotatable and foldable rigid connecting rod is further provided; meanwhile, a pulling force sensor which is arranged along the elastic connecting line can be used for monitoring the connection condition of the cable at any time; the clamping and fixing apparatus provided by the invention adopts a two-piece type clamping bracket with a rotary shaft open-close structure; replaceable elastic clamping and fixing claws are arranged, so that the cable is prevented from being damaged in the clamping and fixing operation; and the fixation requirements of multiple kinds of different cables can be satisfied as well.

Description

technical field [0001] The invention belongs to the technical field of power transmission, in particular to the technical field of connection equipment between a power supply equipment end and an electric equipment end, and particularly relates to a cable connection tension buffering device. Background technique [0002] In recent years, the electrification of construction machinery has gradually become a development trend. However, most of the existing construction machinery is powered by internal combustion engines, which have high energy consumption, high emissions, and serious pollution; Most of them adopt hydraulic transmission powered by internal combustion engine, but the power matching of internal combustion engine and hydraulic pressure cannot give full play to the capabilities of internal combustion engine and hydraulic system. Electricity is a relatively clean energy source, which can achieve full power matching when applied to construction machinery, save energy,...
