Support type universal drilling machine

Abstract

This invention discloses a bracket type all directions drilling machine; it includes bracket, drilling machine and connecting device. The connecting device is consisted by connecting parts, rotation parts and clamp parts. The connecting parts include connecting backplane and rotation pin jointed on its central hole. The rotation parts includes rotating dead plate, rotating pin bush and all kinds of bolts, one end of rotating pin bush is jointed to rotating dead plate. Clamp parts include left half loop sleeve, right half loop sleeve, hinge pin, short hinge sleeve long hinge sleeve, cotter pin and stiffener. Hinge sleeve is jointed on each of the two half loop sleeves and connected to hinge pin, left half loop sleeve is jointed to rotating pin sleeve. Connecting backplane is fixed at certain height of the bracket, rotating pi is inserted in rotating pin sleeve, and rotating dead plate is fixed through bolt. Any directions of drill hole can be realized and labor intensity is reduced, and drilling speed is high.

Description

technical field [0001] The invention relates to drilling equipment, in particular to a drilling equipment used for bolt support drilling installation in all directions of coal mine roadway wall surface and for water and gas exploration. Background technique [0002] The extensive promotion of bolt support technology in coal mines requires drilling operations in all directions on the roadway wall. The utility model patent application number is 200520022875.8. The "piston rod propulsion type rock bolt rig" is driven by an air motor through a reduction box to reduce the speed and increase the torque, and then drive the drill pipe to rotate. It is propelled by a multi-stage cylinder and controlled by a control arm. Vertical drilling of the roof and installation of bolts; the bolting of the two gangs needs to be drilled with a coal electric drill, or the "helping anchor cable drilling rig" disclosed in the utility model patent No. 032453841 is used for drilling operations.

The utility model patent application number is 200520022875.8. The "piston rod propulsion type rock bolt rig" is driven by an air motor through a reduction box to reduce the speed and increase the torque, and then drive the drill pipe to rotate. It is propelled by a multi-stage cylinder and controlled by a control arm. Vertical drilling of the roof and installation of bolts; the bolting of the two gangs needs to be drilled with a coal electric drill, or the "helping anchor cable drilling rig" disclosed in the utility model patent No. 032453841 is used for drilling operations. Drilling operations need to be driven by manpower, which is labor-intensive and slow in drilling speed, and cannot even drill hard rocks; it is difficult for existing drilling rigs to drill holes at any angle; The previous drilling was more than 10 meters long, and it was found that there was no danger of water and gas gushing out. Now this kind of operation is completed by a special hydraulic engineering drilling rig, which requires drilling rigs with different powers to work in turn on the tunneling surface, making the tunneling work more efficient. Surface space is crowded and efficiency is reduced
