Mine handheld hydraulic drilling rig based on multi-action inner curve radial hydraulic motor

Abstract

The invention discloses a mine handheld hydraulic drilling rig based on a multi-action inner curve radial hydraulic motor. The drilling rig comprises a rig body upper casing, a rig body lower casing, the multi-action inner curve radial hydraulic motor, a coupling, a drill pipe and a drill bit. Handholding rods are mounted on left and right sides of the rig body upper casing to control the hydraulic drilling rig by the aid of holding force of palms; high-pressure oil enters the multi-action inner curve radial hydraulic motor from an oil inlet in a central area of the rig body upper casing and pushes pistons and cross beams in the multi-action inner curve radial hydraulic motor to press towards the inner curve surface of a stator, rollers are located on the cross beams, are directly contacted with the inner curve surface of the stator and act mutually to produce axial force to push a rotor to rotate so as to drive the drill pipe to rotate to drive the drill bit to drill holes. The mine handheld hydraulic drilling rig has the advantages that stress balance is realized, the handholding rods of the drilling rig are easy to hold, the torque is large, the safety is high and the like.

Description

technical field [0001] The invention relates to the technical field of mining equipment, in particular to a mining hand-held hydraulic drilling machine based on a multi-action inner curve radial hydraulic motor. Background technique [0002] Mining hand-held drilling rigs are mainly used in coal mine tunneling, blasting holes for caving, bolt holes, gas drainage and detection holes, water exploration holes, water injection holes, coal and rock layer reinforcement or grouting holes for fire prevention and other small diameter projects . In order to meet the needs of national coal mine safety production, coal mine underground drilling machinery is included in the management of mining product safety signs, so as to reduce the safety accidents of mechanical injury in drilling operations and ensure the safety of coal mine underground drilling engineering. [0003] Originally, small hand-held drilling rigs used in mines in my country included coal electric drills and air-coal dri...

AI Technical Summary

Problems solved by technology

[0014] The technical problem to be solved by the present invention is to provide a mining hand-held hydraulic drilling machine based on a multi-action inner curve radial hydraulic motor, to overcome the potential safety hazards of the coal electric drill in the mining electric drill, the air-coal drill has a small drilling capacity, and the volume Large, loud noise, large dust during work, harsh working environment, and manual operation of wind coal drills is difficult; hand drills that use gear hydraulic motors and cycloid hydraulic motors as driving structures have unbalanced force on the motors, and the drill holds the rod when operating manually It is not easy to control, which brings great difficulties to the manual operation on site
