Abstract
The utility model relates to a deflective wedge type metal rockbolt, which is composed of a wedge block (1), a deflective wedge (2), a bolt body (3) of a rockbolt and a supporting plate (4), wherein the wedge block forms a screw connection with the bolt body of the rockbolt; the top of the deflective wedge is provided with a metal hook which can be put at the upper end of the bolt body of the rockbolt during installation. The rockbolt has the advantages of convenient installation, easy recovery and large anchoring force. The utility model is suitable for roadways and engineering adopting rockbolts for support and protection in coal mines and other mines.
Description
The utility model is a kind of colliery side wedge type anchor metal.Form by voussoir, inclined to one side wedge, anchor rod body and supporting plate.Can be applicable to colliery and other mines and adopt the tunnel and the engineering of bolt support.
Existing side wedge type anchor metal is made up of voussoir, inclined to one side wedge, anchor rod body and supporting plate.Bundle with iron wire between voussoir and the inclined to one side wedge.Voussoir and anchor pole are welded as a whole.The weak point of this anchor pole is: 1. be difficult for reclaiming.When anchor hole has distortion slightly, then voussoir and partially wedge be stuck, can't reclaim.2. need artificial hammering when installing, not only labour intensity greatly but also be difficult for grasping the installation site.3. randomness is too big during owing to anchoring, and anchoring property is poor, and anchored force is little.
The weak point that the purpose of this utility model is to overcome prior art provides a kind of easy recovery, easy for installation, side wedge type anchor metal that anchoring property is good.
The purpose of this utility model can reach by following measure:
Voussoir changed into anchor rod body be threaded.At inclined to one side wedge top metal hook is arranged, take during installation and be placed on the anchor rod body upper end.
Fig. 1 is a kind of embodiment of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing:
1 is voussoir among Fig. 1, the 2nd, and inclined to one side wedge, the 3rd, anchor rod body, the 4th, supporting plate.The lower end of anchor rod body can be square or hexagonal also can be that screw rod is equipped with nut.At the top of voussoir metal hook 5 is arranged, take and be placed on the anchor rod body upper end.Use is as follows: the anchor pole that assembles is packed in the anchor hole.When supporting plate contact top board, the body of rod turns clockwise.This moment, the body of rod rose, and body of rod head pushes up inclined to one side wedge and rises, and voussoir is done downward relative motion simultaneously, and wedge slides along wedge surface partially, voussoir and wedge wedging in anchor hole partially, and anchor pole promptly is anchored in the anchor hole.When needing to reclaim anchor pole, the inhour rotation body of rod, the hammering body of rod afterbody that makes progress then, voussoir rises along wedge surface, and anchoring is removed.Anchor pole can all reclaim.When anchor hole has distortion, when the whole recovery of anchor pole are had any problem, the body of rod can be back-outed from voussoir, the body of rod and supporting plate can obtain reclaiming.
Compared with prior art the utlity model has following advantage: since voussoir and the body of rod it Between adopt and to be threaded and change that voussoir and the wedge of be connected connect so that rockbolt installation makes things convenient for and pacifies Packing quality improves, and corresponding anchor force improves. Anchor pole reclaims easily in addition, has greatly improved time The receipts rate.
Claims (1)
1. colliery side wedge type anchor metal, be made up of voussoir (1), inclined to one side wedge (2), anchor rod body (3) and supporting plate (4), it is characterized in that, voussoir adopts with anchor rod body and is threaded, metal hook is arranged at the top at inclined to one side wedge, takes during installation to be placed on the anchor rod body upper end.
