The rock bolting front canopy device of the mine driving face is moved forward in an alternation mode, safety of operation personnel can be guaranteed, and working with no protection is avoided.
Description
Technical field
The utility model relates to a kind of coal mine evacuation working face bolt support front cantilever apparatus, belongs to the Bolt Supporting in Roadways field.Do temporary lining when mainly being applicable to the roadway supported by bolt driving.
Background technology
In the shaft and drift supporting, bolt support is modal a kind of support form, and its temporary lining is puzzlement constructor's a difficult problem always, and what have does not reach the temporary lining effect, and implementing of having is cumbersome, time-consuming, effort.Existing temporary lining is: make forestope with track or i iron, be suspended on the roll bolt with the metal suspension ring, and with in time reach of construction, lay wooden large plate on it, length and lanewidth are suitable.This forestope is done the suspender suspension with the metal suspension ring and is fixed on the intact roll bolt of supporting, after forestope moves forward with construction, meeting head on can't be at the lower anchor pole of beating of temporary lining with the anchor pole of forestope in-line arrangement, must wait all the other anchor poles set complete after, recalling forestope could set again, not only lose time, increased labor strength, and have potential safety hazard.Working procedure is: tap, look for clean crag and the cash of living → move forestope (temporary lining) → permanent support (to beat square, skyhook) → withdraw forestope (temporary lining) → permanent support (beat, fill blue anchor pole, linked network, put the beams in place, finish the roll bolt supporting).For a long time temporary lining is always merely nominal, has both affected construction speed, is unfavorable for again safe construction.
Summary of the invention
The problem that temporary lining exists when tunneling for solving roadway supported by bolt, the utility model provides a kind of coal mine evacuation working face bolt support front cantilever apparatus.
The utility model is realized with following technical scheme: a kind of coal mine evacuation working face bolt support front cantilever apparatus, it comprises forestope and forestope is suspended on suspender on the roll bolt that described suspender comprises jack nut, suspended screw, top board, bottom plate, upper lifting nut and lower lifting nut; Suspended screw passes the bottom-up bottom plate that is arranged in order, lower lifting nut, top board, upper lifting nut is connected with jack nut and is connected with lower lifting nut, upper lifting nut thread, and its upper end is fixedly connected with jack nut and is fastened on the roll bolt by jack nut; Described forestope cross section is flute profile, has a bar hole along the forestope length direction on the bottom land of forestope, and the bar hole width cooperates with suspended screw; Forestope is placed between top board and the bottom plate and goes here and there on suspended screw, and an end is fixed on the mounted roofbolt, other end interception empty top zone.
Two of described suspenders are one group, and two suspenders are arranged apart along bar hole, jointly hang a forestope.
The ascending, descending nut rises or decline makes forestope contact the tight front-probe support effect of playing with roof rock by regulating; The constructor temporary lining is lower beat anchor pole after pretension finish permanent support.Then the null term operation is avoided in circulation reach, guarantees operating personnel's personal safety, and supporting effect is good.
The beneficial effects of the utility model are: simple in structure, and light and flexible, easy to use, alternating forward, time saving and energy saving, can guarantee operating personnel's personal safety, avoid the null term operation, supporting effect is good.
