Abstract

The invention discloses a light-type full-hydraulic drilling machine for underground drilling of a coal mine. The light-type full-hydraulic drilling machine comprises a stander, a drilling rod, a water braid, a guide rail, a propelling hydraulic cylinder, a hydraulic clamp and a drill power head, wherein the hydraulic clamp comprises a clamp base, a supporting seat, a clamping hydraulic cylinder and a clamp clamping tile; the water braid comprises a water braid shell, a water braid shaft, a water braid hollow shaft, two anti-abrasion ring, an isolating ring, a front end cover, a rear end cover and an anti-abrasion sealing ring; the drill power head comprises a speed reduction box body, a connection frame, a gear shaft, a hollow stepped shaft, a hydraulic motor, a spring mounting seat, a spring limiting seat, an end face check ring, a gear, a disk-type spring group, a power head clamping tile and a clamping hydraulic cylinder. The light-type full-hydraulic drilling machine is compact in structure, convenient and low in cost; the energy consumption is reduced, the power transmission efficiency is improved, and the clamping force on the drilling rod is stable and reliable; the service lives of the anti-abrasion sealing ring and the water braid shaft can be prolonged, the replacement trouble is reduced, the construction progress and safe production are guaranteed, vibration of the drilling machine is reduced, and the drilling rod is prevented from being broken.

Description

technical field

[0001] The invention belongs to the technical field of drilling rigs, and in particular relates to a light full-hydraulic drilling rig for underground drilling in coal mines. Background technique

[0002] With the further mining of coal in my country, the characteristics of thin coal seam and deep occurrence are becoming more and more obvious, coupled with the regional differences in the distribution of coal resources in my country, the problem of gas drainage has become increasingly prominent. The gas drainage drilling rig is mainly used for drilling gas drainage holes, outburst prevention and pressure relief holes, coal seam water injection holes and other underground holes in coal mines. At present, the fully hydraulic drilling rigs used in small and medium cross-section gas drainage tunnels are mainly composed of four major parts: pump station, main engine, column frame and console. The main engine includes power head, supporting plate device, frame, wate...
