Retaining and protecting vehicle for coal mines

Abstract

The invention discloses a retaining and protecting vehicle for coal mines. The retaining and protecting vehicle is characterized in that a complete machine body (9) is arranged on a traveling device (10), a track (7) is arranged on the complete machine body (9), a sliding trolley (8) is arranged on the track (7), the lower end of a support arm (3) is articulated on the trolley (8), the upper end of the support arm (3) is articulated on a protecting plate (2) which can be used for fixing and installing a steel beam (1) to be erected, one end of an oil cylinder (5) is articulated with the support arm (3), the other end of the oil cylinder (5) is articulated with the complete machine body (9), and a complete machine control system (4), a machine electrical system (11) and a complete machine pump station system (6) are arranged on the complete machine body (9). The retaining and protecting vehicle for the coal mines has the advantages of being capable of meeting the retaining and protecting requirements of a large tunnel roof and increasing the safety of retaining and protecting.

Description

technical field [0001] The invention relates to a mine support mechanism, in particular to a mine support vehicle for large roadway support. Background technique [0002] At present, there are mainly two forms of roadway roof support at home and abroad: one is to use the joist on the cutting part of the underground roadheader for support. The disadvantage is that it takes time and effort to erect the heavy steel beam on the cutting part of the machine This operation is basically done directly by manual work, and there are huge potential safety hazards. People are often injured in mines, and in severe cases, people die. Safety, but this method still cannot meet the requirements of loading steel beams on the support, manual handling is still required, and full mechanization cannot be achieved, and this support cannot meet the needs of erecting heavy steel beams and other workpieces in large roadways; for this drawback, The support vehicle designed by the invention can meet th...
