Description
Technical field
The utility model relates to a kind of tunnel integrated parallel installation device of full section anchor shaft anchor cable and method, be mainly used in mine working bolting and rope support engineering, this device can become one with other laneway temporary support devices or the auxiliary means of locomotion of installing.
Background technology
Mine engineering comprehensive mechanized driving bolt support construction technology, because it is safe and reliable, singly enter efficiency far above traditional big gun tunneling process, at present by wide popularization and application.A circulation of comprehensive mechanized driving bolt support construction technology main consuming time in tunneling machine cutting and roadway support.How to improve jewel hole facility, how to improve rockbolt installation speed, how to realize the parallel installation of multiple anchor poles, how to realize roadway support and tunneling machine cutting parallel operations, from eighties of last century the fifties so far, Mining At Home And Abroad circle has carried out a large amount of explorations, and has produced a lot of technology and equipment.
Existing jumbolter has pick anchor integral type, machine-carried type, drill carriage formula, monomer-type by structure difference; By broken rock principle difference, there are swinging, impact type, impact rotating formula, rotary-percussion; By mechanism's power difference, there are fluid pressure type, pneumatic type, electrodynamic type.Wherein in jumbolter structure, dig anchor integral type, drill carriage formula is the main object of current technological progress.
Pick anchoring integral development machine, from sixties first generation anchor driving machine, be born and carried out so far twice large change, third generation pick anchoring integral, although realized the parallel operations of pick anchor, bolt support unsupported back span is large, generally more than 1.2-1.5 rice, supporting can not be immediately following meeting head on, so, be only applicable to dark little, the ore deposit of Bian and press little, the preferably large Cross-Section Rectangular of wall rock condition or trapezoidal tunnel, therefore, never applied widely.As China's overwhelming majority mining area, open the Bian degree of depth darker, ore deposit is pressed large, the conditions such as country rock soft broken, anchor pole is intensive, even also needs linked network, cable bolting, and support work amount is large, not only unsupported back span is from can not meet requirement, and support time, much larger than the cut time, is also difficult to synchronize with cut.
In recent years, the progress of roofboltier is very fast, by both arms, four arms, develop in the recent period at the Shenhua eastern great Liu tower of the god saddle ride type eight arm jumbolter high speed driving systems that use of going into the well, this system is comprised of six kinds of equipment such as anchor driving machine, saddle ride type eight arm roofboltiers, self adaptation leather belt reshipment machine, crawler type self-movable foot end, step type self-movable foot end, two arm roofboltiers, and wherein saddle ride type eight arm roofboltiers are nucleus equipments wherein.Saddle ride type roofboltier and anchor driving machine and other coordinative composition of equipments operations, after job order place anchor driving machine, car load is equipped with 8 drill booms, be respectively Anchor Care drill boom after 4 front Anchor Care drill booms, 2,2 lateral wall Anchor Care drill booms, divide front and back 3 to arrange and put, car load straddles on self adaptation leather belt reshipment machine, props up protective function form complementation with two arm roofboltiers, even complete independently, to the whole supportings of back anchor pole, completes the supporting task to part lateral wall anchor pole simultaneously.This system only support apparatus configuration just has anchor driving machine, eight arm roofboltiers, three equipment of two arm roofboltiers, wound the first in the world.By above-mentioned introduction, being also not difficult to find out, there is following problem in this system:
1. condition of compatibility harshness.Wall rock condition will be got well, and unsupported back span is from the condition of compatibility of wanting to meet anchor driving machine.
2. system complex.Only supporting just has anchor driving machine, eight arm roofboltiers, three equipment of two arm roofboltiers.
3. there is certain problem in security reliability control.By anchor driving machine, eight arm roofboltiers, two arm roofboltiers, implement tunnel permanent support, it is larger that three equipment takies lane space in tandem, permanent support span is large, side country rock in top is difficult to be controlled in time, there is certain potential safety hazard, if play anchor cable, lapping, disturb each other larger.
Although 4. three support apparatus cooperatively interact, each root anchor pole is first by mobile rocking arm jewel hole more in place, installation, be difficult to realize the full section anchor pole in tunnel, anchor cable one step in place, install simultaneously.
