Multifunctional two-arm hydraulic drilling equipment for fully-mechanized coal mining face

Abstract

The invention provides multifunctional two-arm hydraulic drilling equipment for a fully-mechanized coal mining face, and belongs to the technical field of coal mine drilling. The multifunctional two-arm hydraulic drilling equipment comprises travelling chassis assemblies, supporting seat assemblies, lifting arm assemblies and drilling arm assemblies, wherein the travelling chassis assemblies are arranged on the two sides of a fully-mechanized coal mining face scraper conveyor and can travel along the side walls of the fully-mechanized coal mining face scraper conveyor; the two supporting seatassemblies are arranged on the travelling chassis assemblies along the side walls of the fully-mechanized coal mining face scraper conveyor, and each supporting seat assembly comprises a stand column,an operating valve set and a cantilever; each lifting arm assembly comprises a slewing bearing I, an extendable oil cylinder II, a lifting arm I, a lifting arm II, a drill boom hanging plate, an extendable oil cylinder III and a steel wire rope I; and each drilling arm assembly comprises a slewing bearing II, a drilling arm I, a drilling arm II, an extendable oil cylinder IV, a drilling mechanism, a steel wire rope II, a steel wire rope III and a fixed pulley. According to above the multifunctional two-arm hydraulic drilling equipment for the fully-mechanized coal mining face, the all-dimensional multifunctional drilling requirement of the fully-mechanized coal mining face can be achieved, and the problem that a traditional drilling mode is small in drilling range, low in hole distribution efficiency and poor in safety guarantee is solved.

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...
