Description

Anchor Drilling Compound Machine

technical field

The invention relates to coal mine roadway excavation and mining and anchoring drilling protection machinery, specifically a new type of integration of tunneling machine, bolter, and drilling machine-a bolter-drilling compound machine, which realizes the continuous operation effect of the integration of three machines.

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; and for high-gas roadways, about 15 gas release holes with a diameter of 100 mm and a depth of more than 20 meters need to be drilled in the front section before the roadheader excavates. At present, it is completely done by manual operation. Manual drilling and drilling are not only labor-intensive, but also very low in efficiency. Therefore, there is a great need for a compound machine that can perform bolt anchoring and deep hole drilling immediately after the roadheader excavates. Continuous work reduces the labor intensity of the operator and increases the footage speed of the roadheader.

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.

2. The cantilever of the main arm is too long and the stability is not good.

3. There is no support when driving the side bolt, and the failure rate is high during work.

4. The working position of the bolter is too high to be suitable for bolting operations in low tunnels.

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. Installed on the upper part of the slewing table of the roadheader, the empty head distance is limited, and 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 and the stability is not good.

5. It is only suitable for roadways with rectangular or trapezoidal sections.

Chinese Utility Model Patent (Application No. CN94242297.X) discloses an airborne rock bolt drilling machine for excavation. The column in the drilling machine is arranged in the slewing mechanism on the main frame of the excavator, and the main arm is arranged perpendicular to the column. The support swings, and the front end of the main arm is provided with a propulsion mechanism. The utility model replaces the manual drilling and installation of anchor rods by a single anchor rod drilling machine in the current domestic fully mechanized coal excavation, reduces the time for empty roof and help, meets the support requirements of the excavation empty roof area, ensures the safety of workers, and improves degree of mechanization.

Its disadvantages are:

1. Installed on the rotary table of the roadheader, the height of the whole machine is too high, which will affect the working performance of the roadheader.

2. The cantilever of the main arm is too long and the stability is not good.

3. The whole machine is a single anchor rod, and the working efficiency is low.

4. The working position of the bolter is high, and the range of applicable roadways is small.

Chinese utility model patent (patent No. 95242039.2) discloses a kind of roadheader integrated anti-outburst drilling machine, and this drilling machine is made up of main engine and hydraulic pressure part, and main engine is made up of frame, rotating body, slide plate, feed oil cylinder again. The main engine is installed on the cutting arm of the roadheader and integrated with the roadheader. The cutting arm of the roadheader swings up and down, left and right under the action of the hydraulic pressure of the roadheader pump station, and the main engine of the drilling rig swings accordingly to adjust the drilling position and drilling angle of the drilling rig. The drilling rig not only has the advantages of small size, light weight, convenient installation, operation and maintenance, but also reduces labor intensity and improves work efficiency. Its shortcomings are as follows:

(1) The drilling machine is always fixed on the cutting arm, which affects the tunneling operation and the tunneling space is also limited;

(2) Above the cutting part of the drilling machine, the drilling range is limited, and holes that are too high and too low cannot be drilled;

(3) The drilling machine cannot shrink, is not flexible enough, and the scope of application is also limited;

(4) The hydraulic system is complex and difficult to operate.

In addition to the deficiencies in the above-mentioned patent documents, the three-in-one composite structure of the roadheader, the bolter and the drilling machine cannot be realized.
