[0040] In this embodiment, a force arm scraper is provided at the front end of the mechanical operating arm. In other embodiments, a drill, a hydraulic pick, or a hydraulic metal shear may also be provided.

[0041] In this embodiment, the forearm and the rear arm of the mechanical arm cannot be telescoped. That is, they are a single rod. In other embodiments, they may also be telescopic, as Figure 3 shown.

[0042] The mechanical operating arm is a prior art and belongs to a bionic machine of the human arm. The rear arm can rotate, the forearm can rotate relative to the rear wall, and the operating tool at the front end of the front wall can also rotate relative to the front wall.

[0043] Tunnel driving work process:

[0044] The four crossbeams of the utility model are supported on the top support of the roadway, connecting the steel beams for top support of the roadway together to fix the support. On both sides of the front support feet, the mechanical operating arms of the operators use scrapers to dig the socket for the leg of the support steel beam and brush the sidewall, etc. The operator on the left operates the winch to transport materials to the site; the operator on the operating platform operates two scraper arms to dig the socket for the support steel beam and brush the top, etc. After the work such as digging the socket, the socket for the column, brushing the sidewall and brushing the top is completed, the operator on the operating platform operates a mechanical operating arm to lift the support steel beam into place, and another operator on the operating platform operates another mechanical operating arm to assist in placing the lifted support steel beam into place. The mechanical operating arms of the operators on both sides of the front support feet use scrapers to place the legs of the support steel beam in place. The telescopic plate of the operating platform extends under the push of the hydraulic cylinder, providing an operating platform for the staff to fix the support steel beam leg support, lay the protective net and other support materials. After the work of fixing the support steel beam leg support and laying the protective net and other support materials is completed, the telescopic plate of the operating platform retracts under the pull of the hydraulic cylinder. The scraper arms or hydraulic picks on the four mechanical operating arms of the front support feet scrape the coal or rock at the roadway face onto the conveyor and transport it away.

[0045] After the coal or rock at the roadway face is cleared, the two front telescopic columns at the front support feet fall back, and the crossbeam falls back and disengages from the steel beam for top support of the roadway. The first hydraulic cylinder 12 and the third hydraulic cylinder 21 extend simultaneously, pushing the front end of the combined equipment for roadway repair and tunneling forward. After the front support feet move into place, the two fixed columns at the front of the front support feet rise, and the crossbeam rises and contacts and fixes with the steel beam for top support of the roadway.

[0046] The two rear telescopic columns at the rear of the front support feet fall back, and the crossbeam falls back and disengages from the steel beam for top support of the roadway. The first hydraulic cylinder 12 and the third hydraulic cylinder 21 retract simultaneously, pushing the rear end of the combined equipment for roadway repair and tunneling forward. After the rear end moves into place, the two rear telescopic columns on the rear support feet rise, and the crossbeam rises and contacts and fixes with the steel beam for top support of the roadway. One working cycle is completed.

[0047] The work process of roadway repair:

[0048] The work process of the combined equipment for roadway repair and tunneling for roadway repair is basically the same as that for roadway tunneling, except that after the work of fixing the support steel beam leg support, laying the protective net and other support materials is completed, there is the removal work of the original support steel beam leg support. The mechanical operating arm scrapers on the upper and lower operating platforms of the combined equipment for roadway repair and tunneling dig out or pull out the support steel beam leg support, or metal cutting scissors can be installed on the mechanical operating arm to shear the support steel beam leg support or the connecting bolts and clamps to accelerate the work process.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present utility model. Any equivalent replacement of the present utility model and any modification or partial replacement that does not depart from the spirit and scope of the present utility model shall be covered by the scope of protection of the claims of the present utility model.
