Underground maintenance vehicle for coal mine

Abstract

The invention discloses an underground maintenance vehicle for a coal mine, which is a trackless rubber-tire vehicle comprising a frame and a carriage. The underground maintenance vehicle is characterized by further comprising a hydraulic lifting platform, the carriage is arranged above the rear end of the frame, and the hydraulic lifting platform capable of moving up and down is arranged at the top of the carriage. The hydraulic lifting platform comprises a telescopic cylinder and a movable table arranged at the top of the telescopic cylinder, a cylinder pole of the telescopic cylinder exactly faces a position below the movable table, and a hydraulic system is arranged on the frame and connected with the telescopic cylinder through a pipeline. The underground maintenance vehicle for the coal mine solves the problem that ascent is extremely inconvenient so as to bring great troubles to subsequent maintenance work of lighting equipment when the lighting equipment in roadways is maintained in the prior art. Besides, the underground maintenance vehicle for the coal mine is provided with the lifting platform so as to be convenient for maintenance staff to ascend to perform maintenance work.

Description

technical field [0001] The invention belongs to the technical field of transportation vehicles, in particular to a coal mine underground transportation and maintenance vehicle. Background technique [0002] With the application of roadheaders, roadway maintenance has become one of the basic tasks to maintain the normal production of coal mines. There are a large number of lighting rods in the underground roadway. During long-term use, the lamp tubes are often damaged, and the falling stones in the roadway break the light wires and other reasons to reduce the brightness of the roadway, which has a great impact on the personnel who work in the roadway. Therefore, regular and timely maintenance of the lighting in the roadway is required. [0003] However, due to the existence of gas in underground coal mines, ordinary maintenance vehicles with lifting platforms cannot enter the roadway for maintenance. At the same time, due to the limitation of the height of the lighting equi...
