Description

Recyclable resin anchor

The utility model belongs to stope of coal mines roadway support articles for use.

At present, known resin anchor has the screw thread of certain screwing length with a reinforcement fabrication, an end car of reinforcing bar, the certain-length of the reinforcing bar other end is pounded twisted into twisted shape after flat, has promptly made resin anchor.A threaded end is called the holder anchor end of anchor pole, has an end of twisted shape to be called the anchored end of anchor pole, and twisted shape partly is called the anchorage head of anchor pole, and the other parts beyond the twisted shape are called the body of rod of anchor pole.Anchorage head tears and stirs the resin cartridge bag in the boring, and anchorage head and coal body are bonded together, and loads onto pallet at holder anchor end then, and anchor pole has just played anchorage effect like this, promptly reinforcement effect has been played in the tunnel.When coal-winning machine is adopted the tunnel that these anchor poles are housed, must be at first these anchor poles be removed, otherwise the pick of coal-winning machine will damage, also can cause other unsafe factor.Because the body of rod of known resin anchor and anchorage head are one, anchorage head sticks together with coal body again, these anchor poles must adopt hand digging or the way of blowing out digs anchor pole come so remove, underground labour's labour intensity is very much not said, also because of being bonded with the resin that has solidified on the anchor pole, and make the anchor pole can't be multiplexing, cause waste of material.As seen, known resin anchor exists two to lack limit: the one, and the dismounting difficulty is big; The 2nd, can't be multiplexing after removing.Except that known resin bar, domestic someone once manufactured experimently a kind of recyclable resin anchor, the anchorage head of this anchor pole is a metal anchorage head, the anchorage head and the body of rod pass through thread connection, the body of rod can be back-outed with spanner, and reusable, anchorage head is stayed in the coal body, because of the metal anchorage head of staying in the coal body can not be cut by coal-winning machine, cause a large amount of damages of coal winning machine cutting bit, the cost of this anchor pole is higher in addition, causes the use of this anchor pole to be restricted, and present this anchor pole is stopped using on the colliery.As seen, also there are two problems in this recyclable resin anchor that once occurred: the one, and the metal anchorage head of staying in the coal body can not be cut; The 2nd, cost is higher.

The purpose of this utility model provides a kind of recyclable resin anchor, and the body of rod of this anchor pole can be back-outed with spanner, and no longer needs hand digging and the method for blowing out to dig anchor pole; The body of rod of this anchor pole is non-stick resin after reclaiming, can be directly multiplexing; After the body of rod of this anchor pole reclaimed, the anchorage head of staying in the coal body can be cut by coal-winning machine, and did not damage the pick of coal-winning machine.

The purpose of this utility model is achieved in that the anchorage head of anchored end peace at anchor pole, this anchorage head is made of jointly nut, anchoring cartridge, joint ring, stifled ring, plug, wherein nut and anchoring cartridge are requisite parts, and other parts can suitably be accepted or rejected according to conditions down-hole and processing conditions.The anchorage head and the body of rod link by nut, have avoided contacting of the body of rod and resin, the body of rod of anchor pole can be back-outed with spanner, and no longer need to dig anchor pole with the mode of excavating and blow out, non-stick resin on the anchor rod body that reclaims out and can be multiplexing.The body of rod reclaims the back anchorage head and stays in the coal body, constitutes in the material of anchorage head, and because of working of plastics most volumes that account for, the less nut of volume is wrapped up by resin again, so anchorage head can be cut by coal-winning machine.

Below in conjunction with accompanying drawing the utility model is further specified.

Fig. 1 is the assembling drawing of the concrete scheme of the utility model.

Fig. 2 is the replacement of parts figure of anchoring cartridge [5].

Fig. 3 is the another kind of replacement of parts figure of anchoring cartridge [5].

Fig. 4 is the replacement of parts figure of nut [6].

Fig. 5 is the another kind of replacement of parts figure of nut [6].

In Fig. 1, the body of rod [1] is the recyclable part of anchor pole, and its anchored end car has the screw thread of certain screwing length, and its holder anchor end is identical with the anchor pole of other kind, does not draw here.Baffle ring [2] is welded on the body of rod [1], and its effect is the anchorage length that limits anchored end.Stifled ring [3], joint ring [4], anchoring cartridge [5], nut [6], plug [7] common combination constitute anchorage head, wherein anchoring cartridge [5] and nut [6] be anchorage head must indispensable parts, visual underworkings condition of other parts and processing conditions are are suitably accepted or rejected, and this point is described later.Stifled ring [3] is a round pad that has mesopore, and its effect is to prevent mountain pass outside resin is solidifying before, and joint ring [4] is a round rubber sheet gasket that has mesopore, and its effect is to prevent from that the screw thread of anchored end from intaking to get rusty; Anchoring cartridge [5] is-plastic sheath of individual hollow, have spiral helicine overlap on its excircle, and its effect is an agitating resin and by resin and coal body bonding, forms the load basis of anchor pole; Nut [6] plays anastomosis, and anchorage head connects with the body of rod [1] by nut [6]; Plug [1] plays plugging action, and resin is not contacted with screw thread.Assembling will be blocked up the anchored end that ring [3], joint ring [4] and anchoring cartridge [5] are set on the body of rod [1] respectively during anchor pole, and the nut [6] that will have plug [7] then is screwed on the screw thread of anchored end and compresses anchoring cartridge [5], promptly assemble to finish.During skyhook, the anchored end of the anchor pole that assembles inserted be equipped with in the boring of resin cartridge bag, make the anchor pole rotation, the anchorage head of anchored end inserts and agitating resin gradually, anchorage head and coal body are bonded together, at the holder anchor end tray of anchor pole, promptly install then.When coal-winning machine is adopted the anchor pole position, need at first remove anchor pole, promptly reclaim anchor pole, the way of recovery is: remove earlier pallet down, apply moment of torsion at holder anchor end to anchor pole with spanner then, the body of rod [1] and nut [6] are broken away from, extract the body of rod [1] then out, promptly realize the recovery of anchor rod body [1], and anchorage head is stayed in the coal body, the body of rod that reclaims out [1] is gone up non-stick resin, mixes new anchorage head, can be multiplexing once more.The anchorage head of staying in the coal body can be cut by coal-winning machine, and reason has two: the first, and working of plastics is accounting for most volumes of anchorage head, and this part can be cut by coal-winning machine by the working of plastics that resin wraps up; The second, metal nuts [6] is wrapped up by resin, and its volume is very little, and its size is much smaller than the spacing of coal winning machine cutting bit, so do not influence the coal-winning machine coal cutting.

The utility model is in the process of specifically implementing, and the anchoring cartridge [5] and the nut [6] of anchorage head part are absolutely necessary, and are cores of the present utility model, are not requisite and block up ring [3], joint ring [4], block up bucket [7].When stope drift active workings do not have trickle, the problem that the anchored end screw thread gets rusty just can be without a moment's thought, joint ring [4] can be given up in this case need not, can be processed into one to anchoring cartridge [5] and stifled ring [3] simultaneously, anchoring cartridge [5] is if adopt extrusion die to add man-hour, its shape can be selected Fig. 2 and shape shown in Figure 3, nut [6] also can adopt Fig. 4 and the non-standard nut of blind hole abnormity shown in Figure 5, when nut [6] adopts the non-standard nut of blind hole abnormity, plug [7] then can save need not, though saved plug [7] like this, if under the unsuitable situation of processing conditions, can cause the rising of anchor pole cost.
