Problems solved by technology

[0003] Roof bolters are commonly used mechanized support equipment in large coal mines. There are mainly bolters produced in Australia and the United Kingdom. There is no similar domestic model in China. At present, the bolters used in large coal mines in China mainly rely on imports. However, the technology blockade of imported equipment is relatively common. Its structure is complex, the failure rate is high, maintenance is difficult, the supply cycle of vulnerable parts is long, and the price is high. Some key technologies do not meet the explosion-proof standards of coal mines in my country, and it is difficult to meet the high-efficiency support of large mines. equipment needs

Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings.

[0034] As shown in Figures 1, 2, and 3, this drilling rig is a large and heavy machine with a dead weight of more than 40 tons. Since it operates in the harsh environment of the underground, all electrical components have been designed for explosion-proof; machine base 1, traveling mechanism 2. The workbench 3, the drill frame assembly 7, the slide rail assembly 8, the support assembly 9 and the lifting mechanism form a complete machine model; The slide rail assembly 8, the support assembly 9, the hopper 4, the left and right material racks 6, the ceiling 5, the lift cylinder 14 and the lifting mechanism fall, the height is reduced, the center of gravity is balanced, and the machine base 1 and each mechanism are placed on both sides. On the top of the traveling mechanism 2, the whole machine is also in this state when it travels for a long distance, so the two travelin...

Abstract

The present invention relates to a crawler running roof-bolting jumbo for coal extraction in the pit. It mainly includes machine seat, working table, running mechanism, lifting mechanism, hydraulic mechanism, dust-removing mechanism, cable-rolling mechanism, drilling cramp component, slideway component, support component and electric control box, said whole machine adopts hydraulic transmission, automatic dust-removing, automatic cable-rolling and crawler running modes, and utilizes the hydraulic oil cylinder to control parallelogram lifting movement and can make moving, lifting and multi-arm roof-bolt drilling works in the excavating tunnel. Said invention is reasonable in structure, large in load-bearing capacity, reliable and high in working efficiency.

Description

technical field [0001] The invention relates to a crawler-type rock bolter, which belongs to the technical field of design and manufacture of roadway support anchor drilling equipment for underground mining in coal mines. Background technique [0002] In modern large-scale coal mines, the development and support of underground mining roadways is very important, and it is the main means for safe operation and prevention of coal seam subsidence. [0003] Roof bolters are commonly used mechanized support equipment in large coal mines. They mainly include bolters produced in Australia and the United Kingdom. There are no similar domestic models in China. At present, the bolters used in large coal mines in China mainly rely on imports. However, the technology blockade of imported equipment is relatively common, its structure is complex, the failure rate is high, maintenance is difficult, the supply cycle of vulnerable parts is long, and the price is high. Some key technologies do ...
