Abstract
The utility model discloses an anchor-drawing support for supporting and protecting the surrounding rock the top plate of roadway and crosspoint, composed of symmetrical anchor rods at both sides, and a draw rod connected with the anchor rods, wherein, the draw rod is provided with double rings at both ends or is in the shape of a lathy ring; the two anchor rods are symmetrically anchored to the drillings of the surrounding rock; the intermediate draw rod is sheathed on the anchor rods at the both sides. The draw rod is appressed with the surrounding rock the top plate through the fastening of shim plates and bolts; thereby, the draw rod not only can form a horizontal extruding force to the top plate, but also can form an upward reaction to the top plate; so the stability of the top plate can be ensured efficiently. The utility model has the advantages of simple structure, and simple and practical manufacture and construction craft.
Description
The utility model relates to a kind of mine working support, and the novel anchor of more specifically saying so draws support, and it is widely used in underground all kinds of engineering, and the supporting of big lane, crosspoint, mining roadway, especially stope drift active workings mainly is the roof rock in supporting tunnel.
In the prior art in roadway support field, different because of country rock type, supporting place and purposes, the support pattern of employing is also different.So-called anchor draws support, it is a kind of peculiar support form that is combined by anchor pole and pull bar, it is reported, with the utility model comparatively approaching be a kind of support form that use in Cheng Zihe ore deposit, Jixi, this support is made up of main rope, stop bar or chock, because due to the restriction of its construction technology and the structure of itself, main rope can not be strained effectively.For pull bar is strained, it is to install to spend this take-up device of blue button on pull bar that a kind of method is arranged, and also having another method is to utilize comparatively complicated pull bar and anchor pole connector, by being threaded, tightens pull bar.More than the anchor of all these types draw support, its supporting purpose all is in order to produce horizontal compressive force in roof rock, make roof rock stable, based on this supporting purpose, caused owing to use take-up device or anchor pole and pull bar connecting elements, and make pull bar break away from the result of roof rock scar, and these several anchors draw support more complicated aspect mounting process, and on the high side.
Supporting purpose of the present utility model is to make pull bar not only will form the interior horizontal compressive force of roof rock, but also to produce reaction force upwards to the top board scar, only in this way could guarantee the stable of roof rock effectively, based on this kind supporting purpose, thereby it is simple to have designed a kind of construction technology, pull bar is strained effectively, can be made pull bar be close to the top board scar again, having upwards to top board, the novel anchor of reaction force draws support.
The purpose of this utility model can realize in the following way:
A kind of novel anchor draws support, is made up of monosymmetric anchor pole and the intermediate draw bar that is attached thereto.Two anchor poles are anchored in the country rock boring symmetrically, anchor pole can be the anchor pole or the pipe seam formula friction anchor pole of termination or full length fastening, intermediate draw bar is dicyclo pull bar or the elongated ring-type pull bar that there is closed-loop at two ends, the material that pull bar is selected for use is reinforcing bar or wire rope, the both side ends of pull bar is sleeved on respectively on the anchor pole of both sides, compress by backing plate, bolt, make pull bar be close to the top board scar.
Novel anchor described in the utility model draws support compared with prior art, pull bar not only can be strained effectively, and can also be close to the top board scar, it promptly is the extruding force that pull bar not only can form horizontal direction to top board, and top board there are upwards reaction force, the stability of assurance top board with being effective.Characteristics such as this support also has simple in structure, and manufacturing and construction technology are simple, and be easy for installation.
Description of drawings:
Accompanying drawing 1 is a mounting structure schematic diagram of the present utility model.
Accompanying drawing 2 is partial schematic diagrams of the utility model dicyclo steel bar rod.
Accompanying drawing 3 is partial schematic diagrams of the utility model dicyclo wire rope pull bar.
Accompanying drawing 4 is partial schematic diagrams of the elongated ring-type pull bar of the utility model.
The embodiment that provides at accompanying drawing is further described the utility model below:
Shown in accompanying drawing 1, a kind of novel anchor draws support to be made up of monosymmetric anchor pole and intermediate draw bar, comprise anchor bar body 1, pull bar 2, anchoring agent cartridge bag 3, backing plate 4, levelling packing ring 5 and nut 6, anchor bar body 1 can be the pipe seam body of rod that the reinforcing bar body of rod or steel band are rolled into, pull bar 2 has the dicyclo pull bar of closed-loop for two ends, its material is reinforcing bar or wire rope, takes welding or wire clips mode to constitute two end ring respectively, shown in accompanying drawing 2,3.Pull bar 2 also can adopt elongated ring-type pull bar, with a reinforcing bar two ends butt welding that designs length in advance circlewise, again by the designing requirement hoop become elongated ellipse (or with two reinforcing bar two ends with the bar dowel welding also can), there is both sides, anchor pole place respectively to weld a bar dowel in the centre and forms, as shown in Figure 4.During installation, anchoring agent cartridge bag 3 is put into foot of hole by Len req, anchor bar body 1 is passed an end ring of pull bar 2, insert in the boring, after the anchoring agent is solidified, load onto backing plate 4, levelling packing ring 5, fastening nut 6, thus install nation's anchor pole, then in a symmetrical side, utilize above-mentioned same method that nation's anchor pole down is installed, constitute a cover anchor and draw support, this anchor draws the pull bar 2 of support to be close to the top board scar, the counter-force of making progress for top board one, the stability of assurance roof rock.When if anchor pole is installed with mechanical equivalent of light feeding device, then nut 6 can be fixedly welded on the afterbody of anchor bar body 1, anchor bar body 1 passes the end ring of pull bar, and backing plate 4, levelling packing ring 5 utilize mechanical equivalent of light feeding device to push boring in the lump.
Claims (3)
1, a kind of novel anchor that is mainly used in supporting back country rock draws support, comprise anchor pole and pull bar, it is characterized in that: pull bar (2) has the dicyclo pull bar or the elongated ring-type pull bar of closed-loop for two ends, the two ends of pull bar (2) are set on the monosymmetric anchor pole (1), by backing plate (4), levelling packing ring (5) and nut (6) are fastening, make pull bar (2) be close to the top board scar.
2, novel anchor according to claim 1 draws support, it is characterized in that: the selected material of pull bar (2) can be reinforcing bar or wire rope, constitutes two end ring or the middle elongated ring-type pull bar that adds bar dowel by welding or wire clips respectively.
