In order to effectively remove the anchor cable lock on top board, be convenient to being caving of top board, existing Mine anchorage cable lockset detaching device comes for coal mine roadway, release and recovery ground tackle.But the heavy 25KG of device that existing Mine anchorage cable lockset is removed, many people compounding practice is needed during installation, move back about about 10 minutes of anchor time, personnel will lift anchor restorer body always, labour intensity is comparatively large and move back residue stress that in anchor process, lockset produces and chip is easily hurted sb.'s feelings, operation inconvenience, operating efficiency is not high, brings certain potential safety hazard to production.
Utility model content
Technical problem to be solved in the utility model is to provide modified form anchor restorer, described modified form anchor restorer is a kind of special-purpose machines and tools dismantled from back by coal mine roadway prestressed anchor cable anchorage, moveable anchor is furnished with in these special-purpose machines and tools, firmly grasping of anchor cable steel strand can have been moved back and forth with operating cylinder inner carrier, loosening up, thus dismounting anchor cable lock, and sling is set by the correct position on anchor restorer body and uses fixed pulley and steel cable, by the hanging of anchor restorer body on top board, realize simply carrying out disassembling section to anchor cable lock dexterously.
In order to solve the problems of the technologies described above, the technical solution of the utility model is achieved in that
Modified form anchor restorer, comprises double speed Reversing oil pump, high-pressure oil pipe assembly, anchor restorer body, boom hoisting; Double speed Reversing oil pump is communicated with the oil inlet pipe that anchor restorer body is arranged, oil return pipe by high-pressure oil pipe assembly; The top dead center position of anchor restorer body offers gathering sill, and the centre position of gathering sill is provided with centre bore, and this centre bore runs through anchor restorer body; Moveable anchor is provided with in anchor restorer body; Middle part circumference on anchor restorer body is fixedly installed sling, and sling is by steel cable hanging on fixed pulley, and sling, steel cable, fixed pulley form boom hoisting.
Further, described moveable anchor is stretch-draw jack, anchor cable steel strand penetrate in the centre bore of anchor restorer body by gathering sill, and this moveable anchor completes the action of firmly grasping, loosening anchor cable steel strand automatically along with the reciprocating motion of operating cylinder, realize moving back anchor cable lock operation;
Further, described sling has 6, and sling circumference is welded on the middle part on anchor restorer body;
Further, described anchor restorer body upper part side is provided with suspension ring, in anchor restorer body handling process, as the position captured, fix, for anchor restorer transport provides convenient.
The utility model beneficial effect compared to existing technology:
The utility model is convenient to the disassembling section of Mine anchorage cable lockset, operating efficiency is high, safety is high, achieve simply, dexterously by anchor restorer hanging carry out on top board anchor cable lock move back anchor operation, eliminate the potential safety hazard that the chip that produces in lockset demolishing process is easily hurted sb.'s feelings, reduce the labour intensity of operating personnel.Specifically:
1, the utility model eliminates and moves back residue stress that lockset in anchor process produces and the hidden danger that top board chip is easily hurted sb.'s feelings, and solves because heavy (weight 25kg) inconvenience of bringing.
2, the utility model eliminates and moves back residue stress that lockset in anchor process produces and the hidden danger that chip is easily hurted sb.'s feelings, and improves work efficiency and has greatly put forward safety factor.
3, the utility model machined latch closure, by the hanging of anchor restorer body on top board, can reduce the labour intensity of operating personnel during use by pulley.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, modified form anchor restorer, comprises double speed Reversing oil pump, high-pressure oil pipe assembly, anchor restorer body 4, boom hoisting; Double speed Reversing oil pump is communicated with the oil inlet pipe 9 that anchor restorer body 4 is arranged, oil return pipe 8 by high-pressure oil pipe assembly; The top dead center position of anchor restorer body 4 offers gathering sill 5, and the centre position of gathering sill 5 is provided with centre bore 6, and this centre bore 6 runs through anchor restorer body 4; Moveable anchor is provided with in anchor restorer body 4; Middle part circumference on anchor restorer body 4 is fixedly installed sling 3, and sling 3 is hung on fixed pulley 1 by steel cable 2, and sling 3, steel cable 2, fixed pulley 1 form boom hoisting.
Described moveable anchor is stretch-draw jack, and anchor cable steel strand penetrate in the centre bore 6 of anchor restorer body 4 by gathering sill 5, and this moveable anchor completes the action of firmly grasping, loosening anchor cable steel strand automatically along with the reciprocating motion of operating cylinder, realizes moving back anchor cable lock operation;
Described sling 3 has 6, and sling 3 circumference is welded on the middle part on anchor restorer body 4;
Described side, anchor restorer body 4 top is provided with suspension ring 7, in anchor restorer body 4 handling process, as the position captured, fix, for anchor restorer transport provides convenient.
The course of work of the present utility model and using method:
The first step: by fixed pulley hanging in the intact position of top board, anchor restorer body is connected through sling with steel cable, personnel can be in beyond 5m and pull steel cable, only need two workmans by light for anchor restorer body pull-up, to use fixed pulley to sling anchor restorer body to correct position.
Second step: anchor cable steel strand are penetrated the intrinsic centre bore of anchor restorer by the gathering sill on anchor restorer body, ensure that the intrinsic moveable anchor of anchor restorer engages with anchor cable steel strand to put in place, keep anchor restorer body front end distance anchor cable lock 60 ~ 70mm simultaneously, the operating valve handle pulling double speed Reversing oil pump clockwise makes anchor restorer intrinsic tool anchor clamp Automatic-clamping anchor cable steel strand and anchor cable steel strand do extensional motion along with the intrinsic piston of anchor restorer, and the motion with anchor cable steel strand is drawn out anchor cable lock cover by the anchors of anchor cable lock;
3rd step: after taking out the anchors of anchor cable lock, the operating valve handle pulling double speed Reversing oil pump counterclockwise makes the intrinsic tool anchor clamp of anchor restorer automatically unclamp anchor cable steel strand and the intrinsic piston of anchor restorer does contractile motion returns to initial position, anchor cable steel strand are taken off from anchor restorer body, then steel cable is untied, transfer anchor restorer body, so far complete and move back anchor operation.
In sum, these are only preferred embodiment of the present utility model, be not intended to limit protection domain of the present utility model.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
