Bolter miner integrated with digging and anchor

technical field

The invention relates to coal mine roadway excavation, mining and supporting machinery, in particular to a bolter digging machine, a new integrated model of digging and bolting, which realizes the integrated effect of the tunneling machine and the bolter.

Background technique

At present, the support work of the roadheader after tunneling is a difficult, complicated and extremely inefficient work. The main reason is that the separate work of the roadheader and the bolter has caused a lot of waste of time, and the effective working time ratio is very small. Manual bolting is not only labor-intensive, but also inefficient. Therefore, there is a great need for an airborne bolter that can immediately perform bolting work after the tunneling machine excavates, so as to improve the working efficiency of the tunneling machine and reduce the number of operators. labor intensity.

The Chinese utility model patent (application number CN92243425.5) discloses an airborne telescopic cantilever folding hydraulic rock bolt drilling rig, which is suitable for carrying out "random drilling" in tunnels with a rectangular or trapezoidal cross-section in coal mines. Roof Bolting". Two identical drilling rigs are installed on the rotary table of the roadheader through the drill base, and can drill holes at the same time. The hydraulic power is supplied by the roadheader oil pump. When working, the drilling rig cantilever is extended. The hydraulic folding mechanism lowers the drill stand. The horizontal swing cylinder enables the drill frame to determine the hole position. The supporting mechanism makes the drilling frame withstand the roof of the roadway. The propulsion device on the drill stand pushes the hydraulic motor drill to drill holes.

Its disadvantages are:

1. The bolter is installed on the upper part of the rotary table of the roadheader, not only the empty head distance is limited, but also the bolt in the low roadway cannot be drilled.

2. The rock bolt rig has no self-rotating device, so it cannot drill corner bolts.

3. The function of the cutting part of the roadheader is not used, and there are few positions for bolting.

4. The cantilever of the main arm is too long, the stability is not good, and the strength and reliability are poor.

1. The bolter has an independent hydraulic station, operating console, etc., resulting in two hydraulic stations on one machine, which costs a lot and takes up a lot of space.

2. The cantilever of the main arm is too long, the stability is not good, and the strength and reliability are poor.

3. The height of the whole machine is too high, the volume and quality are too large, the structure is complicated, and the operation is inconvenient.

4. The corner bolt cannot be drilled, and the applicable roadway range is small.

Chinese Utility Model Patent (Application No. CN02234476.4) discloses a roadheader airborne bolter, which includes a main arm, a column and a drill frame. The column is arranged in the telescopic oil cylinder of the roadheader, and its upper end is vertically hinged with a main arm , the drill is erected at the front end of the main arm, and the main arm adopts a chain plate, and a slewing mechanism is provided on the main arm, so that the rock bolt rig realizes all-round drilling and anchor protection functions while achieving synchronous operations of digging and anchoring ; This drilling rig is small in size, light in weight, simple in structure, safe in working condition and easy to operate.

Its disadvantages are:

1. The bolter is installed on the rotary table of the roadheader, and the height of the whole machine is too high, which affects the performance of the roadheader.
