Automatic hydraulic drilling machine for coal mine

Abstract

An automatic hydraulic drilling machine for a coal mine comprises a drilling execution device, a manipulator, an automatic drill rod box and a caterpillar band travelling mechanism, wherein the caterpillar band travelling mechanism is used for supporting and moving the drilling execution device, the manipulator and the automatic drill rod box. The manipulating manipulator is controlled by a PLC programmable control system to extract drill rods from the automatic drill rod box and place the drill rods on the drilling execution device, and drilling operation is completed through the drilling execution device. According to the automatic hydraulic drilling machine for the coal mine, power is supplied to the drilling machine by a hydraulic pump and a motor; and through the PLC programmable control system, the automatic drill rod feeding and discharging function of the drill rod box of the drilling machine, the automatic drill rod disassembling function of the drilling execution device and the automatic drill rod grabbing function of the manipulator are achieved, so that labor intensity of workers is effectively lowered, operation and production efficiency is improved, and the personal safety coefficient of the workers is increased.

Description

technical field [0001] The invention relates to the field of underground mining equipment, in particular to an automatic hydraulic drilling machine for coal mines. Background technique [0002] With the intensification of coal mining, the depth of coal mining gradually deepens, the difficulty of mining becomes greater, the environment becomes harsher, and the labor intensity of workers is also greater. In recent years, coal mine safety accidents have occurred frequently, and major and extraordinarily large safety accidents often occur suddenly, which are difficult to prevent and deal with, and easily cause casualties and economic property losses. Most of the existing underground coal mine equipment requires operators to operate at close range, especially for coal mine drilling rigs. At least 4 workers are required to work on site each time drilling to ensure the entire operation process. The entire operation process relies entirely on the workers to operate the equipment on...

AI Technical Summary

Problems solved by technology

The entire operation process relies entirely on the workers to operate the equipment on the spot. Not only is the labor intensity of Caocheng workers very high, but also the work efficiency is low, especially in the event of a safety accident, there is no way to guarantee the personal safety of the workers.
