Abstract
The utility model relates to a mine working timbering or reinforcing adopting mine anchor rope, comprising an anchor rope body (1), an anchor rope rigging and a tray (5). The anchor body is processed by a steel stranded wire whose outside steel wire is helical ribbed steel wire, namely, the outer surface of the steel wire is provided with a helical rib. The anchor rope rigging is composed of an anchor ring (4), a clip (3) and an O shaped ring (2), or composed of an extrusion cover (7), a connecting spring (9) and a nut (8). The anchor rope body cakes and anchored with a hole wall through anchor cement. When the anchor cement adopts resin anchor cement, the steel stranded wire is required left twirling and the helical rib is required left revolving. Adopting the anchor rope body of the steel stranded wire process of the utility model can fasten the cementation between the anchor rope body and the anchor cement and improve the anchorage force by 30 percent so as to improve the bearing capacity of the anchor rope and improve the laneway timbering effect.
Description
Technical field
The utility model relates to the anchor cable that supporting such as underground roadway, tunnel or reinforcing are used, the Mine anchorage cable that particularly a kind of colliery is made the anchor cable body, constituted with anchoring agent anchoring, with rigging and pallet with, steel strand.
Background technology
China Mine Geological condition more complicated, along with the increase of pit mining intensity with adopt dark continuing to increase, be fit to adopt I, II, the III class tunnel proportion of common bolt supporting more and more littler, and the IV of roadway surrounding rock less stable, V class tunnel proportion are increasing, especially are subjected to high seam workings subject to dy namic pressure, soft-rock tunnel and the proportion increase of tunnel, compound top of tunnel that the deep bump influences, top coal caving the most obvious.These several tunnels need to adopt anchor cable to carry out reinforcing with common bolt supporting difficulty is very big merely.Along with the development of bolt support, anchor cable begins developed and application as a kind of reinforcing measure of coal mine roadway bolt support in recent years.The steel strand processing resin anchor cable of at present domestic main employing Φ 15.2mm, Φ 17.8mm.The anchored force that the back generation is solidified in the anchoring agent of anchor cable is high more favourable more to supporting.The adhesion strength of the raising of anchored force and anchoring agent and anchor cable body has direct relation.
Summary of the invention
In order further to improve the adhesion strength of existing its steel strand anchor cable body of anchor cable and anchoring agent, the utility model provides a kind of Mine anchorage cable, the structure of the used steel strand of its anchor cable body is more conducive to and anchoring agent secure bond, improve the adhesion strength of anchor cable body and anchoring agent, and then improve the anchored force of anchor cable.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be:
Mine anchorage cable is made up of anchor cable body, anchor cable rigging and pallet.The anchor cable body is by the steel strand processing and fabricating, and the cover wire of steel strand adopts helix rib steel wire, and promptly the external peripheral surface of steel wire has spiral ribs.The anchor cable body is by anchoring agent and borehole wall bonding.The anchor cable rigging is made up of anchor ring, intermediate plate and O shape circle.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted can also be:
The anchor cable rigging of Mine anchorage cable by with anchor cable body afterbody fixed for one extruded sleeve and be connected spring, and be assemblied in the nut composition on the extruded sleeve external screw thread; Remaining structure of this Mine anchorage cable is the same.
When resin anchoring agent was used in the anchoring agent of Mine anchorage cable, the rotation direction of making the steel strand of anchor cable body was necessary for left-hand lay, and the spiral ribs of steel strand steel wire is left-handed.The length of anchor cable rigging will extend 15 ± 5% than common anchor cable rigging.The spiral ribs of the steel wire of steel strand is 2～4.
The beneficial effects of the utility model are:
The anchor cable body adopts the steel strand manufacturing of helix rib steel wire, and is more firm with anchoring agent bonding, makes anchored force improve more than 30%.Thereby the supporting capacity of raising anchor cable is improved the roadway support effect.

Fig. 3 is the structural representation of another kind of anchor cable rigging of the present utility model.
Among the figure: 1-anchor cable body, 2-O shape circle, 3-intermediate plate, 4-anchor ring, 5-pallet, 6-spiral ribs, 7-extruded sleeve, 8-nut, 9-connect spring.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
At the utility model Mine anchorage cable shown in Fig. 1,2, constitute by anchor cable body 1, anchor cable rigging, pallet 5.Anchor cable rigging or title anchor cable ground tackle are made of anchor ring 4, intermediate plate 3, O shape circle 2.
Anchor cable body 1 is to use the steel strand processing and fabricating, and its length is generally 4～9m.Steel strand are evenly closely to be wrapped in a steel wire twisting by six roots of sensation cover wire helical form to form, and its rotation direction is left-hand lay.The external peripheral surface of six roots of sensation cover wire has spiral ribs 6, and the spiral ribs 6 of steel wire appearance is left-handed.A steel wire of internal layer is circle cross section, is that external peripheral surface is not with spiral ribs.
The spiral ribs of the steel wire of diagram steel strand is 3.The spiral ribs 6 of steel wire can be selected in 2～4.
Be with anchor cable rigging and pallet 5 on the afterbody of anchor cable body 1.
Fig. 3 shows the structure of another kind of anchor cable rigging of the present utility model.Form by extruded sleeve 7, connection spring 9, nut 8.By extruding, the afterbody of extruded sleeve 7, connection spring 9 and anchor cable body 1 is fixed to be one, and nut 8 is installed on the external screw thread of extruded sleeve 7, and tray 5 on the nut 8.Extruded sleeve 7 claims adapter sleeve again.Detailed content is seen utility model patent " Mine anchorage cable ", the patent No.: ZL 02213943.5.
Above-mentioned anchor cable body 1 is with the steel strand processing with the steel wire of left-handed spiral ribs, left-handed twisting, is suitable for the anchor cable with the resin anchoring agent anchoring.If cement anchoring agent is adopted in the anchoring agent, then there is not this requirement.
The length of this Mine anchorage cable rigging is than common anchor cable rigging lengthening 15 ± 5%, better effects if.
Using method: to adopt resin anchoring agent is example.
1. bore the anchor cable hole; 2. anchor cable is installed: in the anchor cable hole of manually resin explosive roll being packed into, with anchor cable resin explosive roll slowly is pushed into the hole at the bottom of, powder stick must not be broken in the installation, then the anchor cable lower end is linked with agitator and jumbolter.3. stir powder stick: start jumbolter, the limit advances, stir on the limit, stirs after 15～20 seconds, stops A and stirs.4. stretch-draw: after 10 minutes ground tackle, pallet can be installed, utilize and the supporting fastening rigging of stretch-draw jack of anchor cable, finish installation.
Processing: make the anchor cable body with the resin anchoring agent anchoring, the rotation direction of used steel strand is necessary for left-hand lay, and the spiral ribs of its steel wire is left-handed.The cutting steel strand must not adopt electricity, gas welding with toothless saw or hydrashear cutter.The cutting length error is not more than 20mm.Avoid the sticking oil stain of steel strand surface etc.
