Abstract

The embodiment of the invention provides an electrometric handcart tool, which comprises a hydraulic power device, a mounting bracket and a pushing device, wherein the hydraulic power device is fixed on the mounting bracket; the two sides of the front end of the mounting bracket are provided with two horizontally extended slot hoes with different heights respectively; the pushing device is arranged in the mounting bracket; the two sides of the front end of the pushing device are provided with two pushing pins with the different heights respectively; the two pushing pins on each side of the front end of the pushing device pass through the two slot holes on the same side of the front end of the mounting bracket from the inner side of the mounting bracket respectively; 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 pushing pins of the pushing device to move to and fro in the slot holes of the mounting bracket; and the throttling valves are arranged in a discharge oil line and a return oil line.

Description

technical field [0001] The invention relates to the field of electric power engineering, in particular to an 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 electric ins...
