Bracket device for drilling rig

Abstract

A support device for a drilling machine comprises a base, two vertical upright, lifting sliding seats, a lifting mechanism, a longitudinal guide rail, an angle adjusting mechanism, a longitudinal sliding seat and a longitudinal pushing mechanism. The vertical uprights are fixedly arranged on the upper end face of the base, each lifting sliding seat sleeves the corresponding vertical upright, a cylindrical supporting column is arranged fixedly between the two lifting sliding seats, the lifting mechanism drives the lifting sliding seats to reciprocate along the vertical uprights, one end of the longitudinal guide rail is connected on the supporting column through a rotary supporting mechanism, the angle adjusting mechanism is arranged between the other end of the longitudinal guide rail and the base, the longitudinal guide rail is driven through the angle adjusting mechanism to rotate along the supporting column to control pitch angle of the longitudinal guide rail, and a drilling rod clamping device is arranged at a position at the upper end of the longitudinal guide rail and on one side away from the vertical uprights.

Description

technical field [0001] The invention relates to a drilling device for coal mines, in particular to a support device for a drilling machine. Background technique [0002] At present, in order to ensure the safety of workers' 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., and the drilling rig must be installed on the bracket when drilling. The position and angle of punching are adjusted by changing the position of the bracket. The conventional bracket device generally includes a main column and a longitudinal guide rail. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention is to provide a support device for a drilling rig, which has a simple structure and good stability, can stably adjust the drilling orientation of the drilling rig, and improve the...

[0002] At present, in order to ensure the safety of workers' 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. When drilling, the drilling rig must be installed on the bracket. The position and angle of punching are adjusted by changing the position of the bracket. The conventional bracket device generally includes a main column and a longitudinal guide rail. Its structure is relatively simple. When adjusting, the whole bracket is not stable and accidents are prone to
