Coal mine tunnel support dismantling equipment

Abstract

The coal mine roadway support dismantling equipment comprises a traction base, the upper end face of the traction base is fixedly connected with a collecting air pump and a collecting box, the upper ends of a fixed collecting rack shaft and a dismantling rack shaft are slidably connected with a crawling sleeve shell, and the lower end of the fixed collecting rack shaft is fixedly connected with a second grabbing base; the upper end of the fixed collecting rack shaft is slidably connected with a crawling mechanism, and the right end face of a fixed telescopic air pump fixedly connected with the right end face of a crawling sleeve shell slidably connected with the upper end of the fixed collecting rack shaft is fixedly connected with a support fixing mechanism. According to the coal mining roadway support dismantling device, a coal mining roadway support plate and fixing bolts of the coal mining roadway support plate can be automatically positioned and fixed in an engaged mode, the mechanization degree and safety of support dismantling work are improved, and the coal mining roadway support dismantling device is convenient to use and high in practicability. Heavy manual dismantling work is replaced, and the utilization rate of the coal mining roadway support plate is increased.

Description

technical field [0001] The present application relates to the field of coal mining, in particular to a coal mine roadway support removal equipment. Background technique [0002] In the field of modern coal mines, especially in the field of underground coal mining, it is usually necessary to expand the coal mining roadway first and then carry out the excavation and mining of the coal mining face. In my country's modern mechanized coal mining industry, the underground coal mining roadway usually adopts the method of reinforcing supports In order to consolidate the support strength of the roadway and prevent roof accidents, after the merger and reorganization of many coal mining industries, large coal mining areas account for most of the output of my country's coal mining industry, and the roadways in large underground coal mining areas are very deep. There are many support plates used to improve the safety of the roof, which often consume a huge amount of steel. In order to incr...

[0002] In the field of modern coal mining, especially in the field of underground coal mining, it is usually necessary to expand the coal mining roadway first and then carry out the excavation and mining of the coal mining face. In my country's modern mechanized coal mining industry, the underground coal mining roadway usually adopts the method of reinforcing the bracket In order to consolidate the support strength of the roadway and prevent roof accidents, after the merger and reorganization of many coal mining industries, large coal mining areas account for most of the output of my country's coal mining industry, and the roadways in large underground coal mining areas are very deep. There are many support plates used to improve the safety of the roof, which often consume a huge amount of steel. In order to increase the number of use of the support plate steel, it is necessary to remove the support plates in all roadways every time the underground coal mine is withdrawn to achieve recycling. The purpose of reducing expenditure and saving energy, and in the modern coal mining industry, most coal mining roadway demolition work needs to be done manually, which has not reached the universally applicable mechanization level, so it is necessary to improve the mechanization of coal mining roadway support plate removal work degree
