Problems solved by technology

[0002] With the development of fully mechanized mining technology in coal mines, comprehensive mechanized coal mining has been widely used, but some coal mines are generally thinner, and the thickness of some coal seams varies greatly. When it is large, it will cause insufficient coal passing space height, and if a thicker coal seam scraper conveyor is used, when the mining height is low, due to the high machine surface height, it will cause a gap between the shearer and the hydraulic support top beam. Insufficient safe space

Embodiment 1

[0013] This embodiment provides a height-adjustable rail structure for coal mine transportation equipment, which is characterized in that: the adjustable height rail structure for coal mine transportation equipment includes groove sides (1), hinged ears (2), pin row rail seats (3 ), pin shaft (4), adjustable pin row rail (5);

[0014] Among them: including the groove side (1), the pin row rail seat (3) is hinged on the groove side (1) through the hinge ear (2), and the adjustable pin row rail (5) is connected with the pin row rail seat through the pin shaft (4) (3) Hinged.

[0015] There are two rows of holes on the adjustable pin row rail (5), and the upper and lower groups of holes are respectively located on the upper and lower two horizontal planes.

[0016] The height is adjusted by adjusting the hinge position of the pin row rail seat (3) and the adjustable pin row rail (5).

Abstract

A coal transportation equipment adjustable-height rail structure is characterized by comprising a cell skull, a hinge lug, a pin row rail base, a pin shaft and an adjustable pin row rail; the pin rowrail is hinged to the cell skull through the hinge lug, the adjustable pin row rail is hinged to the pin row rail base through the pin shaft, two rows of holes are formed in the adjustable pin row rail, and are formed in the upper horizontal plane and the lower horizontal plane correspondingly, and the height is adjusted by adjusting the hinge position of the pin row rail base and the adjustable pin row rail. The coal transportation equipment adjustable-height rail structure has the beneficial effects that the structure is simple, the design is reasonable, the occupied space is small, the coalmining difficulty is reduced, the recovery ratio is improved or the coal mining quality is ensured, the cost is reduced, the production efficiency is high, practicability is high, and the good effectis obtained in the actual use process.

Description

technical field [0001] The invention belongs to the technical field of fully mechanized mining in coal mines, in particular relates to underground transportation equipment for coal mines, and in particular provides a height-adjustable rail structure for transportation equipment in coal mines. Background technique [0002] With the development of fully mechanized mining technology in coal mines, comprehensive mechanized coal mining has been widely used, but some coal mines are generally thinner, and the thickness of some coal seams varies greatly. When it is large, it will cause insufficient coal passing space height, and if a thicker coal seam scraper conveyor is used, when the mining height is low, due to the high machine surface height, it will cause a gap between the shearer and the hydraulic support top beam. Not enough safe space. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned existing technical problems, and es...
