Integrated machine for breaking, loading, carrying, spraying and tunneling of rock roadway

Abstract

The invention relates to an integrated machine for breaking, loading, carrying, spraying and tunneling of rock roadway, comprising a crawler walking part, a gangue pushing and rock rake plate, a belt transportation machine, a rock breaking part, a hydraulic and operation system and a body platform, wherein, the gangue pushing and rock rake plate is arranged at the front of the crawler walking part; and the belt transportation machine is arranged at the back of the plate and at the middle of the crawler walking part. The invention is characterized in that the integrated machine is also provided with a spouting device and a base; the hydraulic and operation system is arranged on the body platform of the upper side of the crawler walking part; and the base is fixed at the front center of the body platform; the rock breaking part is moveably connected on the base; and the spouting device is arranged at one side of a rock-breaking air-hammer. The integrated machine improves cycling schedule and speed of rock roadway tunneling, reduces labor intensity and numbers of constructers, creates safe operation environment, and has the functions of self-moving, gangue breaking, transportation, mechanical wet spouting and the like.

Description

technical field [0001] The invention relates to coal mine underground excavation equipment, which is a construction machine which integrates all processes of rock breaking, rock loading, rock transportation and spraying sealing in the process of rock roadway excavation in large, medium and small coal mines. Background technique [0002] At present, the main method of tunneling in various coal mines is blasting, and the support methods are bolts, anchor cables, joists, anchor nets, and shotcrete combined support. 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; After the support is completed, the roadway is sprayed and closed by manual use of a dry shotcrete machine. There are following problems in this adopting rock roadway excavation construction method: [0003] 1. Non-mechanized operations, gangue crushing...

AI Technical Summary

Problems solved by technology

[0003] 1. Non-mechanized operations, gangue crushing and roadway spraying are all manual operations, and the labor intensity of employees is high

[0004] 2. Slow construction speed

When the gangue width exceeds 300mm, it must be manually crushed, otherwise it will damage the main transportation system, so it will take a lot of time to crush

[0005] 3. Low efficiency: crushing gangue and spraying and sealing are all manual operations, and there are many construction workers, resulting in low operating efficiency

[0006] 4. High production cost: dry spraying system is adopted, and the rebound rate is above 30%.

[0007] 5. Poor working environment: When spraying grout with artificial dry spraying machine, workers work under harsh conditions with dust hazards, which leads to the occurrence of silicosis among employees

[0008] 6. Low safety factor: Construction workers work alternately at high altitudes, 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
