Hydraulic electricity test handcart tool

Abstract

The embodiment of the invention provides a hydraulic electricity test handcart tool, which comprises a hydraulic power device, a fixed mount and a pushing device, wherein the hydraulic power device is fixed on the fixed mount; two long holes which extend in the horizontal direction and have different heights are respectively formed on both sides of the front end of the fixed mount; the pushing device is arranged in the fixed mount; two push pins with different heights are respectively arranged on both sides of the front end of the pushing device and pass through the two long holes on the same side of the front end of the fixed mount respectively from the inner side of the fixed mount; the power output end of the hydraulic power device is fixedly connected with the rear end of the pushing device, so that the power output end drives the push pins of the pushing device to move back and forth in the long holes in the fixed mount; an overflow oilway is formed between an oil discharging oilway and an oil return oilway in the hydraulic power device; and an overflow valve is arranged in the overflow oilway, so that oil in the oil discharging oilway flows back to an oil tank from an overflow channel when oil pressure in the oil discharging oilway overcomes spring pressure in the overflow valve.

Description

technical field [0001] The invention relates to the field of electric power engineering, in particular to a hydraulic electric inspection handcart tool for opening a switch cabinet. Background technique [0002] With the continuous development of the national economy, electricity consumption is also increasing. New substations have sprung up like mushrooms after rain. The high-voltage switchgear is the key equipment that plays the role of on-off, control or protection in power system generation, transmission, distribution, power conversion and consumption. In order to be able to open the high-voltage switchgear, various brands of high-voltage switchgear are equipped with electric inspection handcart tools. These electric inspection handcart tools are all made of pure steel, which are quite bulky and heavy, usually weighing between 200 kg and 500 kg. During the use of the existing electric inspection handcart tools, it is necessary to first set up guide rails, push the ele...
