Narrow-fuselage six-arm fully hydraulic anchor rod anchor cable drill carriage

Abstract

The invention provides a narrow-fuselage six-arm fully hydraulic anchor rod anchor cable drill carriage which is composed of a walking mechanism, a lifting mechanism, a temporary support mechanism, a drilling arm mechanism, a pump station part, an electrical system and a hydraulic system. According to the narrow-fuselage six-arm fully hydraulic anchor rod anchor cable drill carriage, two rotating workbenches are arranged in front of a machine body, and each rotating workbench is provided with two drilling arms which rotate by 90 degrees through the rotating workbenches, the drill carriage is folded to make the narrow fuselage state be only 1.4 m, passing of the drill carriage and an integrated extractor in a roadway is achieved, the drill carriage can be unfolded by 5 meters when reaching a roadway head-on, four front drilling arms mainly hit a top anchor rod, two rear drilling arms mainly hit a top anchor cable and a side anchor rod, the six drilling arms work simultaneously, rapid anchor protection of the roadway can be realized, support efficiency can be greatly improved, tunneling footage is greatly improved, the coal extraction imbalance contradiction is better solved, and safe, efficient and benign development of coal production is promoted.

Description

technical field [0001] The invention relates to the field of bolt drilling rigs used for supporting operations in coal mines, in particular to a narrow-body six-arm full-hydraulic anchor suitable for supporting a fully mechanized excavator for one-time full-section bolt and cable full supporting operations Rod bolt drilling rig. Background technique [0002] China's energy resources are "lack of oil, less gas, and rich in coal", so coal accounts for more than 70% of China's primary energy consumption for a long time. With the rapid growth of China's economy, coal consumption has also continued to increase. By 2020, coal will still account for about 60% of my country's primary energy consumption structure. [0003] In 2013, my country produced 3.7 billion tons of coal, accounting for about 46% of the global total, and consumed about 4 billion tons of coal, accounting for about 49% of the global total. More than 90% of my country's coal production comes from underground mini...

AI Technical Summary

Problems solved by technology

At present, most of the bolt and cable support operations in large and medium-sized coal mines in my country rely on manual use of hand-held single bolters and coal electric drills, which employ many people, have low efficiency, high labor intensity, and poor safety.

In recent years, with the application of the two-arm bolter drilling rig supporting the operation of the fully mechanized excavator, the above shortcomings have been greatly improved, but because the number of its drilling arms is only two, the support efficiency is limited, and it cannot meet the higher requirements. Support efficiency requirements, can not fundamentally solve the contradiction of mining imbalance

[0006] In order to improve the support efficiency, the number of drill arms must be increased. At present, there is no multi-arm (more than two arms) rock bolt rig that is matched with the fully mechanized excavator. The existing four-arm rock bolt rig has a body width (3.5 meters), Unable to pass the car with the fully mechanized excavator; heavy (35-52 tons), serious damage to the floor; mainly used for top bolting, with a small range of functions; it can only be matched with the continuous mining machine, and cannot be matched with the fully mechanized excavator
