Abstract
The utility model discloses a forepoling support of a coal roadway tunneling anchor mesh cable support, comprising a forepoling bar and a forepoling bar clamp, wherein the forepoling bar clamp comprises a bracket; the bracket is provided with a fixed screw hole; a nut is fixed on the bracket and is matched with a lead screw; the top end of the lead screw is provided with a forepoling bar support; a pressure bearing is arranged between the forepoling bar support and the lead screw; and the bottom of the lead screw is provided with an elastic wrench. The forepoling support effectively solves the forepoling bar supporting problem of the coal roadway anchor mesh cable supporting, is convenient to use and optimizes coal roadway tunneling space. The forepoling support is utilized in 32011 North-Down crossheading of a mine, improves the safety of coal roadway anchor mesh cable supporting tunneling and plays important role in safety production.
Description
Technical field
The utility model relates to the advance support of using in a kind of shed shoring construction, is specifically related to the advance support that a kind of anchor net adds the anchor cable combined supporting.
Background technology
Mostly projecting coal bed coal road driving is to adopt the anchor net to add the anchor cable combined supporting along the roof driving.In general shed shoring work progress, must use advance support; Used U type canopy and i iron supporting that comparatively successful front-probe support is all arranged in the past; Do not have effective advance support and adopt this anchor net to add anchor cable combined supporting mode, be unfavorable for Safety of Coal Mine Production.
The utility model content
The purpose of the utility model is the deficiency to above-mentioned prior art, and a kind of coal road driving anchor rete cord supporting front-probe support is provided, and helps Safety of Coal Mine Production.
The technical scheme of the utility model realizes in the following manner: a kind of coal road driving anchor rete cord supporting front-probe support, comprise forestope and forestope clamp, and said forestope clamp comprises support; Support is provided with the anchoring filament hole; Be fixed with nut on the support, nut matches with leading screw, and the leading screw top is provided with the forestope holder; Be provided with pressure bearing between forestope holder and the leading screw, the leading screw bottom is provided with the degree of tightness spanner.
Said anchoring filament hole is a bar hole.
Said forestope is a π type beam.
The utility model efficiently solves the front-probe support problem of coal road anchor rete cord supporting, and is easy to use, optimizes coal road driving space.I use this device by ore deposit crossheading under 32011 north, have improved the safety of coal road anchor rete cord supporting driving, for bigger effect has been played in safety in production.

The specific embodiment
Shown in accompanying drawing, a kind of coal road driving anchor rete cord supporting front-probe support comprises forestope 1 and forestope clamp 2; Said forestope clamp 2 comprises support 2-1, and support 2-1 is provided with anchoring filament hole 2-5, is fixed with nut 2-7 on the support 2-1; Nut 2-7 matches with leading screw 2-4; Leading screw 2-4 top is provided with forestope holder 2-3, is provided with pressure bearing 2-2 between forestope holder 2-3 and the leading screw 2-4, and leading screw 2-4 bottom is provided with degree of tightness spanner 2-6.
Every group of forestope of the utility model 1 uses four forestope clamps 2, earlier forestope card 2 is fixed on the roofbolt screw through anchoring filament hole 2-5, then forestope 1 is fixed on the forestope clamp 2, and method for using is following:
1, used front-probe support hung up properly with forestope clamp 2 before blowing out after, firm on the adjustment screw mandrel 2-4.
2, the utility model will tighten, go up the jail with top board comprehensive engagement, end silk.
3, tap earlier after blowing out, look for group to push up dangerous coal petrography.
4, the adjustment boosting-rod is held exposed top board after making front-probe support stretch out 0.5～0.7m.
5, the rapid good roll bolt of anchor, and hang net and carried on the back the top.
6, after the top is carried on the back well, under forestope, expand group and produce coal on (rock), anchor pole is helped in anchoring two.
In the utility model, said anchoring filament hole 2-5 is a bar hole, like this can be easily fixing front-axle beam clamp.
Said forestope 1 is a π type beam.
