[0002] At present, in order to ensure the safety of workers in underground operations, drilling rigs are used to drill holes in the coal seam in advance, such as drilling anti-outburst holes on the mining surface, coal seam water injection holes or ventilation holes, etc. At present, the drilling rigs used are all ordinary drilling rigs on the market. However, due to the different heights of the coal seam in the mining face, and the different requirements for the number and angle of drilling holes, the drilling rigs used in coal mines generally require high drilling strength and high drilling strength. deep, and has the ability to drill holes in all directions, so ordinary drilling rigs can no longer meet the needs due to their own defects

The invention discloses a thick coal seam fully mechanized mining working face omnibearing hydraulic drill, mainly consisting of a balance support mechanism, a main floor stand, a lifting slide rest, a lifting mechanism, an angle regulating mechanism and a drilling mechanism, wherein the main floor stand is arranged on the balance support mechanism; the lifting slide is arranged on the main floor stand; the lifting mechanism is connected with the lifting sliding rest; the angle regulating mechanism is composed of a drill guide rail, a front support arm and a rear support arm which form a triangle; the length of the front and rear support arms can be regulated; and the inclination angle of the drill guide rail can be regulated by regulating the length of the front and rear support arms. According to the invention, the change of drilling angle is rapidly achieved, and work efficiency of the drill is enhanced. The thick coal seam fully mechanized mining working face omnibearing hydraulic drill has the advantages of flexibility and convenience for moving the whole machine, strong drilling intensity, convenience for operation, high power and high drilling efficiency; and requirement on drilling at all position of the coal seam can be satisfied by one drill without other auxiliary equipment, so that funds are saved for enterprises.
Description
technical field [0001] The invention relates to a drilling equipment used in coal mines, in particular to an all-round hydraulic drilling machine for fully mechanized mining faces in thick coal seams. technical background [0002] At present, in order to ensure the safety of workers in underground operations, drilling rigs are used to drill holes in the coal seam in advance, such as drilling anti-outburst holes on the mining surface, coal seam water injection holes or ventilation holes, etc. At present, the drilling rigs used are all ordinary drilling rigs on the market. However, due to the different heights of the coal seam in the mining face, and the different requirements for the number and angle of drilling holes, the drilling rigs used in coal mines generally require high drilling strength and high drilling strength. It is deep and has the ability to drill holes in all directions. Therefore, ordinary drilling rigs cannot meet the needs due to their own defects. Conten...
