Abstract

The invention provides downhole drilling equipment with a cooling system. The problems that in the prior art, the structure is complex, demounting and mounting are troublesome, replacement of a drilling bit consumes the time, the working efficiency is low, and the cooling effect is not ideal are solved. The downhole drilling equipment comprises a motor, a hand-held handle, a switch, a wire box andthe cooling system, and the motor is fixed by fastening bolts; the lower end of the motor is connected with a transmission shaft, and the transmission shaft is connected with a cam through an adjusting pin and a connecting key; a transmission bearing is arranged in an inner cavity of a bearing sleeve, one end of a transmission rod is connected with the cam through the bearing sleeve and the transmission bearing, and the other end of the transmission rod is in butt joint with the drilling bit through a hole-adjusting nut; and the cooling system comprises a cooling unit, a cooling liquid container and a cooled equipment set which are arranged on the motor. The downhole drilling equipment is compact in structure, reasonable in occupied space, convenient to demount and mount, quick in drilling bit replacement, and high in working efficiency; and the failure rate of the equipment is decreased, and the cooling cost is saved.

Description

technical field [0001] The invention belongs to the technical field of coal mine auxiliary operation equipment, and in particular relates to an underground drilling equipment with a cooling system, which is simple in structure, convenient for disassembly and assembly, quick to replace drill bits, and high in working efficiency. Background technique [0002] In the existing coal mine drilling operations, two drilling methods, manual drilling and machine drilling, are generally used. Manual drilling is labor-intensive and low in work efficiency; although machine drilling is low in labor intensity and high in work efficiency, However, it is necessary to disassemble and replace the drill bit for different holes, and then it can be used after assembly, which is not only troublesome to disassemble, but also has a rather complicated structure. defect. In addition, high-power equipment in coal mines is widely used, and it has been recognized and widely used in the industry under th...
