A multifunctional two-arm hydraulic drilling equipment for fully mechanized mining face

Abstract

The invention provides a multifunctional two-arm hydraulic drilling equipment for a fully mechanized mining face, which belongs to the technical field of coal mine drilling and includes a walking chassis assembly, a support seat assembly, a lifting arm assembly and a drilling arm assembly; the walking chassis assembly is arranged on the fully mechanized mining face The two sides of the scraper machine can walk along the side of the fully mechanized mining face scraper machine; two sets of support seat assemblies are set on the walking chassis assembly along the side of the fully mechanized mining face scraper machine, including the column, the control valve group and the cantilever ;The lifting arm assembly includes slewing bearing Ⅰ, telescopic oil cylinder Ⅱ, lifting arm Ⅰ, lifting arm Ⅱ, drilling arm hanging plate, telescopic oil cylinder Ⅲ and steel wire rope Ⅰ; the drilling arm assembly includes slewing bearing Ⅱ, drilling arm Ⅰ, drilling arm Ⅱ, telescopic Oil cylinder IV, drilling mechanism, wire rope II, wire rope III and fixed pulley. The above-mentioned multi-functional two-arm hydraulic drilling equipment for fully mechanized mining face can realize all-round and multi-functional drilling requirements in fully mechanized mining face, and improves the problems of small drilling range, low hole layout efficiency and poor safety assurance in traditional drilling methods.

Description

technical field [0001] The invention belongs to the technical field of coal mine drilling, and specifically discloses a multifunctional two-arm hydraulic drilling equipment for a fully mechanized mining face. Background technique [0002] At present, many coal mines encounter many complex geological conditions that require drilling in the process of fully mechanized mining, especially when the coal seam contains long rock interlayers and the rock hardness is high, and when the shearer cannot pass through, rock drilling and blasting are required; If the roof is too hard and the roof does not fall off automatically after fully mechanized mining, it is necessary to drill and blast the roof; it is necessary to drill holes in the fully mechanized mining face to study the geology and other conditions. However, due to the narrow space of the fully mechanized mining face, harsh working conditions, and no suitable power source, currently there are hand-held pneumatic rock drills with...
