Multifunctional roadway maintenance and repair machine

Abstract

The invention belongs to the technical field of coal mine underground roadway maintenance and repair equipment, and particularly relates to a roadway maintenance and repair machine which is suitable for an underground coal mine and integrates the functions of milling, digging, crushing, loading, transportation, anchor rod support and the like into a whole. According to the technical scheme, the multifunctional roadway maintenance and repair machine comprises a walking part, a machine body part, a cutting assembly, a drill arm part, a conveying part, an electrical system and a hydraulic system;and the walking part is arranged below the machine body part, the cutting assembly is arranged at the front end of the machine body part, the drill arm part is arranged at the left side of the machine body part, the conveying part is arranged in the middle of the machine body part, the electrical system is arranged at the left side of the machine body part, and the hydraulic system is arranged atthe right side of the machine body part. The machine can rotate by 180 degrees in the horizontal direction and the vertical direction, and the use range of equipment is greatly expanded. Operation isstable, maintenance is convenient, and 360-degree omnibearing positioning can be carried out on an anchor cable hole of an anchor rod through matched rotation of two swing oil cylinders.

Description

technical field [0001] The invention belongs to the technical field of roadway maintenance and repair equipment in coal mines, and in particular relates to a multifunctional roadway maintenance and repair machine suitable for milling, crushing, loading, transportation, bolt support and other functions in underground coal mines. Background technique [0002] With the continuous improvement of the automation level of underground mining machinery in coal mines in my country, some auxiliary roadway maintenance and repair operations are gradually moving towards mechanization in the forming roadways in the narrow underground space, and roadway repair machines gradually replace manual operations. The roadway repair machine has a single function and a small operating range, and some operations still need to be carried out manually. This kind of man-machine alternate operation has long construction time, high labor intensity, and many safety hazards. The gangue and gangue transportatio...

[0002] With the continuous improvement of the automation level of underground mining machinery in coal mines in my country, some auxiliary roadway maintenance and repair operations are gradually moving towards mechanization in the forming roadways in the narrow underground space, and roadway repair machines gradually replace manual operations. The roadway repair machine has a single function and a small operating range, and some operations still need to be carried out manually. This kind of man-machine alternate operation has long construction time, high labor intensity, and many safety hazards. The gangue and gangue transportation cannot meet the requirements of continuous operation, which greatly affects the efficiency of roadway maintenance and repair
