Excavation and anchoring all-in-one machine used for all-rock roadway and tunnel and control method thereof

Abstract

The invention belongs to the technical field of coal mine roadway tunneling and tunnel construction equipment, and discloses an excavation and anchoring all-in-one machine used for an all-rock roadwayand a tunnel and a control method of the excavation and anchoring all-in-one machine. A walking part is connected to the lower side of a body part, a rear supporting part is connected to the lower end of the rear side of the body part, a shovel plate part is connected to the front end of the body part, and a first conveyor part communicating with the shovel plate part is arranged in the middle ofthe body part. The front end of the upper side of the body part is connected with a cutting part. The upper portion of the cutting part is provided with a first platform supporting part and a secondplatform supporting part. The left side and the right side of the body part are connected with sliding rail type anchor rod machine parts. The front ends of the sliding rail type anchor rod machine parts are connected with impact type hydraulic anchor rod drilling machines. The impact type hydraulic anchor rod drilling machine is adopted to achieve the full-rock roadway or tunnel with the hardnessof more than or equal to 6, the ultra-strong drilling capability is achieved, and the drilling efficiency is improved. A cantilever type heading machine is integrated with the impact type hydraulic anchor rod drilling machines and an anchor rod supporting platform, so that the problem of single operation of roadway tunneling and anchor rod supporting is solved.

Description

technical field [0001] The invention belongs to the technical field of coal mine roadway excavation and tunnel construction equipment, and in particular relates to an all-rock roadway and tunnel digging and bolting integrated machine and a control method thereof. Background technique [0002] At present: in the mining of metal ore and non-metallic mines and the construction of hard rock tunnels for railways and highways and the construction of all-rock coal mine roadways, drilling and blasting operations are mostly used, and some equipment such as cantilever roadheaders are used for tunneling. Perform bolt support operations. Bolting operations are mostly carried out manually and require a work platform. Some equipment is equipped with a bolter drilling rig. The drilling effect is average when the rock hardness is above f≥6, and it is impossible to do all-round bolting operations, and the labor intensity of workers is high. [0003] 1. Drill and blast construction [0004]...

AI Technical Summary

Problems solved by technology

[0004] At present, in tunnel excavation, the drilling and blasting method has good geological adaptability, and air-leg rock drills or rock drilling rigs are widely used to drill holes. The main disadvantages

[0005] 1. The demand for tunnel construction workers is large, there are many procedures, the construction organization is complicated, the construction period is long, the amount of over- and under-excavation is large, and the safety is poor;

[0006] 2. Blasting will lead to loosening of the surrounding rock, prone to landslides; prone to over-excavation problems, the harm of over-excavation:

[0007] ① Increased cost;

[0008] ②Increased disturbance to the surrounding rock;

[0009] ③The inner wall surface of the tunnel is uneven, which increases the difficulty of the subsequent work of net spraying, waterproof board laying, and molded concrete lining

[0010] 3. The demand for the amount of explosives is large, the approval and storage are difficult, and the danger is great

[0011] 4. The bolt support platform is too large

[0015] 2. It is necessary to carry out bolt support work with the air-leg type rock bolt rig or some roadheader on-board hydraulic rock bolt rigs. It is inconvenient to manually operate when replacing the drill pipe and anchoring agent.

[0016] 3. When the bolter is in the whole rock coal roadway or tunnel, the drilling efficiency is too low, and the loss of the drill pipe is high, resulting in too long bolting time

[0018] (1) In the construction of drilling and blasting tunnels, the demand for workers is large, there are many procedures, the construction organization is complicated, the construction period is long, the amount of excess and underexcavation is large, and the safety is poor. The problem of over digging, the harm of over digging

[0019] (2) In the existing cantilever type roadheader and manual bolting operation, the strength of the bolting operation is high; it must be anchored with the air-leg type bolter or some roadheaders. Rod support operation, it is inconvenient to replace the drill pipe and anchoring agent manually; the bolter is in the whole rock coal roadway or tunnel, the drilling efficiency is too low, the loss of the drill pipe is high, resulting in the bolt support time is too long long
