Abstract

The invention belongs to the technical field of mining tunneling machinery, specifically relates to a supporting type integrated tunneling-anchoring machine. The supporting type integrated tunneling-anchoring machine comprises an outer frame, an non-crawler tunneling-anchoring machine and an inner frame, wherein the non-crawler tunneling-anchoring machine and the inner frame are arranged inside the outer frame, the non-crawler tunneling-anchoring machine comprises a tunneling-anchoring machine base, a shovel plate star wheel raking pawl mounted on the tunneling-anchoring machine base, a cutting unit and a first scraper conveyor, the inner frame comprises an air draft passage and an inner frame upright post, two shuffling jacks are respectively arranged both sides of the air draft passage, the shuffling jacks are connected with both sides of the tunneling-anchoring machine base respectively; the outer frame comprises bracket seat boxes arranged symmetrically and an outer frame upright post, push-pull jacks are respectively arranged at both sides of the front ends of the outer frame seat boxes, the push-pull jacks are respectively connected with both sides of the front end of the tunneling-anchoring machine. The supporting type integrated tunneling-anchoring machine provided by the invention integrates coal cutting, transportation, temporary supporting, permanent supporting, automatic net laying and protecting functions, is suitable for a horizontal and closely horizontal coal seam, and can realize parallel operation of tunneling and anchoring, thereby achieve the purpose of rapid tunneling of coal road.

Description

technical field [0001] The invention belongs to the technical field of coal mine excavation machinery, and in particular relates to a support type comprehensive bolter. Background technique [0002] At present, the shortcomings of the use of cantilever roadheaders in the roadway in China mainly include the following aspects: [0003] 1. Since the newly exposed roof needs to be supported in time after the coal body is cut by the roadheader, the roadheader must be withdrawn to the back and stop running at this time. Drilling and support workers carry the bolter and support materials from the back of the roadheader to the working face to perform work such as bolting, anchoring, manual hanging of metal mesh, and finishing of support. The labor intensity is high, the working hours are long, and the production efficiency is low ( Generally, the time for supporting the roof is 2-3 times of the coal cutting time), and the supporting roof and the tunneling machine for cutting coal c...

AI Technical Summary

Problems solved by technology

Drilling and support workers carry the bolter and support materials from the back of the roadheader to the working face to perform work such as bolting, anchoring, manual hanging of metal mesh, and finishing of support. The labor intensity is high, the working hours are long, and the production efficiency is low ( In general, the time for supporting the roof is 2-3 times of the time for cutting coal), and the supporting roof and the tunneling machine for cutting coal cannot realize parallel operation

[0004] 2. Since the support workers work without support (especially when installing anchor plates and laying metal mesh), casualties caused by roof caving and zero-skin collapse occur from time to time

[0005] 3. The existing roadheader does not have the function of automatically laying the roof net

[0006] 4. When the existing roadheader excavates the uphill roadway, when the inclination angle of the coal seam is greater than 8 degrees, due to the existence of floating coal under the track of the roadheader, the floor of the coal seam is smooth, resulting in frequent slipping of the roadheader

[0007] Due to the above reasons, at present, the roadheaders produced in China generally cannot achieve the goal of parallel operation of tunneling and support, resulting in many coal mines experiencing unfavorable situations such as low tunneling efficiency, long construction period of new wells, and tense excavation replacement.

Although foreign countries produce bolt-mining integrated machines that can realize parallel operations of tunneling and support, due to the highly integrated equipment, complex structure, high price, and limited scope of use, the actual use ratio in my country's coal industry is not high.
