Problems solved by technology
The installation of anchor loader and temporary support on the roadheader will easily lead to problems such as complex structure, super high and super wide width, many accidents and difficult maintenance.
[0007] Due to the above reasons, the temporary support and bolt anchoring of most domestic mine excavation work have not been mechanized, and they still remain in manual operations.

The invention discloses a walking type anchor protecting all-in-one machine of a front and rear gantry frame, which comprises a main frame, an auxiliary frame and a main and auxiliary frame hauling oil cylinder, wherein the rear end of a main frame crossbeam on the main frame is fixed on a main frame connecting seat; the main frame crossbeam and the main frame connecting seat are respectively and fixedly provided with a main frame front landing leg and a main frame rear landing leg; a front frame is arranged at the front end of the main frame crossbeam and is provided with a hydraulic drilling machine; an auxiliary frame crossbeam on the auxiliary frame is movably connected in the main frame connecting seat, the front end of the auxiliary frame crossbeam is fixedly connected with an auxiliary frame front landing leg, and the rear end of the auxiliary frame crossbeam is fixed on an auxiliary frame connecting seat; the auxiliary frame connecting seat is fixedly provided with an auxiliary frame rear landing leg; and two ends of a main and auxiliary frame hauling oil cylinder are respectively connected with the main frame crossbeam and the auxiliary frame connecting seat. In the machine, the walking type anchor protecting all-in-one machine of the front and rear gantry frame has a simple structure, is operated conveniently, and is capable of moving independently and automatically, and completing temporary supporting, top pilling, and side anchor rod and anchor rope operating of a coal mine digging working surface.
Description
technical field [0001] The invention relates to a mechanical device for excavation and support of underground engineering, in particular to a walking-type integrated anchor and support machine which integrates the functions of anchor installation and support and is capable of independent self-moving. Background technique [0002] Underground engineering construction, such as coal mine excavation, requires temporary support and installation of jacking bolts, side bolts, and anchor cables. At present, most coal mines still rely on cumbersome and backward manual labor to complete these tasks. [0003] The temporary support of the coal mine machine excavation work is mainly the temporary support of the roof. At present, the temporary support of the roof of most coal mines is the front support that is suspended on the roof bolt by manual forward movement after the roadheader completes the cutting of the roadway. From the probing beam to the Wotou, wooden beams or boards are manu...
