Comprehensive mechanized rock roadway tunneling machine

Abstract

The invention provides a comprehensive mechanized rock roadway tunneling machine, which comprises a caterpillar traveling part, a belt conveyer part, a body mounted on the caterpillar traveling part, a top slope anchor rod anchor cable drill, an operating table and a hydraulic and control system, and is characterized by also comprising at least one cutting device, a vertical swing pushing device, a temporary support, a front fixing device and a rear fixing device, wherein the cutting device is arranged on the vertical swing pushing device and is arranged on the front part of the body; the temporary support and the front fixing device are arranged on the two sides of the front part of the body; the top slope anchor rod anchor cable drill is arranged in the middle of the front part of the body; the operating table and the hydraulic and control system are arranged on the body; and the rear fixing device is arranged in the rear lower space of the body. By using the machine, mechanized construction level is further improved, labor intensity of construction personnel and the construction personnel are reduced, field operation environment is improved, occupational diseases are reduced, and safety and working efficiency are improved; and the machine can be suitable for rock roadway construction of various large, medium and small-sized mines.

Description

technical field [0001] The invention belongs to the technical field of underground development equipment in coal mines, in particular to a comprehensive mechanized rock roadheading machine suitable for comprehensive mechanized development operations of underground rock roads in large, medium and small coal mines. Background technique [0002] In the field of coal mine development equipment technology, the main method of traditional rock roadway excavation in various mines is blasting, and the support methods are combined support of bolts, anchor cables, joists, and anchor nets. The gun excavation is drilled, charged, and blasted with an air-leg pneumatic drill; the gangue falling from the blasting is first manually broken and then transported out of the working face by a rock rake machine; protect. There are following problems in this blasting rock roadway excavation construction method: [0003] 1. The excavation section of the roadway is small: the excavation section is ...

AI Technical Summary

Problems solved by technology

[0003] 1. The excavation section of the roadway is small: the excavation section is generally 15m 2 Left and right, when the height of the roadway exceeds 2m, scaffolding must be set up to carry out the construction of the roof anchor rod and anchor cable

[0004] 2. Non-mechanized operations, blast hole construction and gangue crushing are all manual operations. The construction of the top bolt and anchor cable of the supporting roadway is still a single pneumatic drill operation, while the construction of the side anchor rod and anchor cable is operated by a hand-held pneumatic drill. The thrust source of drilling Because of human arms and arms, the labor intensity of workers is high

Since the construction of the anchor bolts and cables mainly relies on manpower, the construction quality of the anchor bolts and cables cannot be guaranteed fundamentally.

[0005] 3. Slow construction speed

[0006] 4. Low efficiency: Since drilling, crushing gangue, and bolt and anchor cable support are all manual operations, there are many construction workers, resulting in low operating efficiency

[0007] 5. Low safety factor: construction workers work alternately at high altitude, and the working safety environment is poor

Drilling, crushing gangue, and bolt and cable support are all carried out under the empty roof, posing potential safety hazards

[0008] 6. Poor working environment: the gun smoke after blasting and the dust during spraying are likely to cause lung diseases of construction workers and affect the health of workers

Still can't get rid of the traditional technology of drilling holes and firing guns to break rocks, and still can't solve the problem of rock roadway excavation with complicated technology and slow excavation progress
