Description
Technical field
This utility model belongs to Surrounding Rock Control Technology field, large deformation lane (tunnel) road, and more particularly to a kind of overall elongation percentage height, duty is reliable, facilitate separately installed high-elongation combination of steel rope.
Background technology
In recent years, along with the mining degree of depth continues to increase, geological conditions was the most complicated, and many drawbacks of anchor cable have come out, and one of them the most serious problem is exactly that elongation percentage is the lowest.As a example by colliery tunnel support, work progress can run into location that rock deformation is violent unavoidably, engineering use cable bolting mostly, i.e. by squeezing into anchor cable with deformation controlling for rock surrounding gateways.During country rock large deformation, although anchor cable can bear high pulling force, but the elongation percentage of anchor cable is required the most high, and the standard elongation percentage of common anchor cable is less than 3%, far from satisfied use requirement.In roadway with large deformation, cable bolting often because extension property the best generation cable body is disrumpent feelings or fastening invalidation, causes roof accident to take place frequently.At present, how by strengthening supporting intensity method to control country rock large deformation, not only waste material and also the most unstable, for lane (tunnel) road supporting, raising anchor cable elongation percentage has become a hot issue.This utility model provides a kind of high-elongation combination of steel rope, there is overall elongation percentage height, low cost, the advantage that easy for installation, operation duration is stable, the above-mentioned series of problems caused because anchor cable elongation percentage is not enough can be solved, it is ensured that lane (tunnel) road supporting safe and reliable.
Utility model content
For the problem that common anchor cable elongation percentage is not enough, this utility model provides a kind of high-elongation combination of steel rope, and this anchor cable has higher elongation percentage, and its limit Fracture Force meets job requirement simultaneously, is removably installed.
It is as follows that this utility model solves the technical scheme that its technical problem used:
A kind of high-elongation combination of steel rope, including cable body, high-elongation sleeve, lockset, pallet, embedded card, ring spring.Its cable body top is anchored in boring deep, high-elongation sleeve is placed on cable body end, cable body constitutes tight connecting device with high-elongation sleeve by embedded card, when ring spring ensures to install, embedded card is regularly arranged on cable body, lockset is anchored on high-elongation barrel end, and makes pallet be close to roadway surrounding rock.
A kind of high-elongation combination of steel rope, the limit Fracture Force of its high-elongation sleeve should be greater than 80% of the limit Fracture Force equal to cable body, can adjust cable body diameter according to the ultimate tensile strength of cable body ultimate tensile strength, high-elongation sleeve, high-elongation sleeve diameter, high-elongation sleeve outer diameter realize this strength matching.
A kind of high-elongation combination of steel rope, is provided with the pawl structure matched with superficial part bore diameter outside its high-elongation sleeve.During to install, can in advance high-elongation sleeve be fixed on naturally during superficial part holes, in order to high-elongation combination of steel rope separately installed.
The beneficial effects of the utility model:
This kind of high-elongation combination of steel rope changes the duty of common anchor cable independent role, high-elongation sleeve and cable body is used jointly to control country rock, be provided simultaneously with high intensity and high-elongation characteristic, solve in large deformation lane (tunnel) road because anchor cable is disrumpent feelings and fastening invalidation and a series of support issues of causing.Meanwhile, this anchor cable reliable operation, separately installed convenience.
Accompanying drawing explanation
When considered in conjunction with the accompanying drawings, by referring to detailed description below, more completely can more systematically understand this utility model and easily learn the advantage that many of which is adjoint, but accompanying drawing described herein is used for providing being further appreciated by of the present utility model, constitute a part of the present utility model, schematic description and description of the present utility model is used for explaining this utility model, is not intended that improper restriction of the present utility model.Wherein:
Fig. 1 is high-elongation combination of steel rope overall structure schematic diagram；
Fig. 2 is cable body and high-elongation sleeve connection principle schematic；
Fig. 3 is high-elongation combination of steel rope tail structure schematic diagram.
Detailed description of the invention
With reference to Fig. 1, Fig. 2, Fig. 3, this utility model is illustrated, a kind of high-elongation combination of steel rope, including cable body 7, high-elongation sleeve 4, lockset 1(as a example by nut fastens), pallet 2, embedded card 6, ring spring 5.Its cable body 7 top is anchored in boring 9 deeps, high-elongation sleeve 4 is placed on cable body 7 end, cable body 7 constitutes tight connecting device with high-elongation sleeve 4 by embedded card 6, when ring spring 5 ensures to install, embedded card 6 is regularly arranged on cable body 7, lockset 1 is anchored on high-elongation sleeve 4 end, and makes pallet 2 be close to roadway surrounding rock.The limit Fracture Force of its high-elongation sleeve 4 should be greater than 80% of the limit Fracture Force equal to cable body 7, can adjust cable body 7 diameter according to cable body 7 ultimate tensile strength, the ultimate tensile strength of high-elongation sleeve 4, high-elongation sleeve 4 internal diameter, high-elongation sleeve 4 external diameter realize this strength matching.
Use high-elongation sleeve 4 and cable body 7 jointly to control country rock, be provided simultaneously with high intensity and high-elongation characteristic, solve in large deformation lane (tunnel) road because anchor cable is disrumpent feelings and fastening invalidation and a series of support issues of causing.
The pawl structure 3 that 10 diameters of holing with superficial part match it is provided with outside the high-elongation sleeve 4 of this kind of high-elongation combination of steel rope.During to install, in advance high-elongation sleeve 4 can be fixed on naturally superficial part and hole in 10, in order to high-elongation combination of steel rope separately installed.The separately installed step of high-elongation combination of steel rope is as follows: first, carries out holing 9 and superficial part reaming 10, and superficial part 10 diameters of holing match with high-elongation sleeve 4 pawl structure 3；Second, Anchor Agent 8 is sent in hole 9, subsequently high-elongation sleeve 4 is inserted in superficial part boring 10, utilize the pawl structure 3 of high-elongation sleeve 4 to make it naturally be fixed in superficial part boring 10, outside hole, reserve the length that can be subsequently mounted lockset 1；3rd, by ring spring 5, embedded card 6 is fixed on cable body 7 relevant position, subsequently cable body 7 is inserted in high-elongation sleeve 4 and boring 9, carry out Anchor Agent 8 and stir；4th, after Anchor Agent 8 solidifies, pallet 2 is placed on high-elongation sleeve 4, and fastens with lockset 1, realize cable body 7 and high-elongation sleeve 4, pallet 2 and the fastening of roadway surrounding rock simultaneously.
As mentioned above, embodiment of the present utility model is explained, but as long as essentially without departing from inventive point of the present utility model and effect, broadly falling into infringement, this utility model can have a lot of deformation, and this will be readily apparent to persons skilled in the art.Therefore, within such variation is also integrally incorporated in protection domain of the present utility model.
