Abstract
The utility model relates to a mine deep hole flexible superlength anchoring device, used for anchoring of a flexible anchoring bolt in a mine deep hole. The utility model is suitable for supporting and protecting roof plates, reinforcing wall sides, and hoisting heavy objects, pulling rootage, etc. The utility model comprises a resin anchoring agent or an expansive cement cartridge capable of quick setting, and the flexible anchoring bolt. The length of the flexible anchoring bolt is from 5 to 25m, and the flexible anchoring bolt is sheathed in a guide conduit which has a bending angle or is flexible; the guide conduit is composed of a plurality of nodes of short guide conduits connected with each other, and the inner diameter of the guide conduit is larger than the maximum outer diameter of the flexible anchoring bolt. When the utility model is installed, the connecting head is connected with a sleeve cylinder of a clamping head of a drilling device, the flexible anchoring bolt not only is an anchoring supporting body, but also is a device for drilling and agitating. After the utility model is installed, the guide conduit and the sleeve cylinder are dismounted. The utility model has the advantages of large anchoring force, simple structure, and convenient operation.
Description
The utility model relates to the mine support field, particularly a kind ofly is used for that down-hole, mine roof timbering, wall group reinforces, weight lifting, equipment fix, draw the deep-hole flexible super-long anchoring device for mine of taking root.
At present, in the prior art of mine support, mining flexible anchoring device has rope bolt, it generally is that the connector of band screw rod of wedge, lower end of falling by the wire cable anchor body of rod, upper end constitutes, or the upper end of the wire cable anchor body of rod is anchor head, is equipped with resin anchoring agent or coagulates the anchoring of expansive cement powder stick soon.This wire rope flexible roof bolt generally is applicable to the shallow bore hole anchoring that 5m is following, for the anchoring of the above deep hole of 5m, because of the wire rope flexible roof bolt is difficult for the deep hole of packing into, and is difficult to resin anchoring agent or coagulates the expansive cement powder stick soon and fully stir, and use as yet at the scene.
Purpose of design of the present utility model is to overcome the weak point in the prior art, and a kind of simple in structure, easy to operate, deep-hole flexible super-long anchoring device for mine of being suitable for the above deep hole anchoring of 5m is provided.
Purpose of design of the present utility model can reach by following measure:
Deep-hole flexible super-long anchoring device for mine includes the resin anchoring agent that anchoring uses or coagulates expansive cement powder stick 4, flexible roof bolt soon, and flexible roof bolt is made of the rods 2 at middle part, the wedge 1 of an end, the connector 3 of the other end, and the termination of connector 3 is a screw rod.The length of flexible roof bolt is 5～25m, flexible roof bolt is sleeved on to have in bent angle or the flexible conduit, conduit forms at least two joint tubulatures connect, the internal diameter of conduit is greater than the maximum outside diameter of flexible roof bolt, when flexible roof bolt is installed, connector 3 links with the sleeve that is contained on drilling tool 7 drill chuck head, and after the installation, conduit and drilling tool 7 and sleeve thereof will unload.
Purpose of design of the present utility model can also reach by following measure:
The rods 2 of deep-hole flexible super-long anchoring device for mine adopts wire rope, and the end that the termination of connector 3 is screw rod, be connected with wire rope is six square toes.
The tubulature that deep-hole flexible super-long anchoring device for mine adopts, its two ends have the male and female bayonet socket to link, and wherein a joint for the bent angle angle of curved conductor 5, curved conductor 5 is: 90 °≤α＜180 °.
The tubulature of deep-hole flexible super-long anchoring device for mine adopts the braided steel wire flexible pipe of band plastics or rubber sleeve, and there is snap joint at every joint flexible pipe two ends.
Compared with the prior art the utility model has following advantage:
1. can solve the anchoring problem of deep hole overlength flexible roof bolt, single anchor-holding force of anchor bolt can reach more than 60 tons.For the roof timbering of down-hole, mine, wall group reinforce, weight lifting, equipment are fixed, draw to take root a kind of new anchor device is provided.
2. simple in structure, easy to operate, applicability is strong.
The drawing of accompanying drawing is described as follows:
Fig. 1: the structural representation of the utility model flexible roof bolt
Fig. 2: the general structure of the utility model anchor device and scheme of installation
Fig. 3: the structural representation of curved conductor
Fig. 4: the structural representation of straight catheter
Fig. 5: the schematic diagram when flexible roof bolt of the present utility model is made roof timbering
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
Fig. 1: the structure that shows flexible roof bolt of the present utility model.Flexible roof bolt is made of wedge 1, the connector 3 at rods 2 and two ends thereof.Rods 2 adopts wire rope, and length is 5～25m, and wedge 1, connector 3 are connected with the two ends compacting of wire rope or weld.The end that the termination of connector 3 is screw rod, be connected with wire rope is six square toes.Six square toes of connector 3 match with the interior hexagonal hole of the sleeve of drilling tool 7.The screw rod of connector 3 terminations is used for loading nut.
Fig. 2: show general structure of the present utility model and installation situation.The resin anchoring agent that anchoring is used or coagulate expansive cement powder stick 4 soon and be loaded in the gun drilling, rods 2 is sleeved in the conduit, and conduit is formed by connecting by curved conductor 5 and straight catheter 6, and straight catheter 6 can be a joint or a more piece.The internal diameter of conduit should be greater than the maximum outside diameter of flexible roof bolt.When flexible roof bolt is installed, connector 3 links with the sleeve that installs additional on the drill chuck head of drilling tool 7, the rotation of drilling tool 7 drill chuck head, to drive connector 3 and the rotation of whole flexible roof bolt by sleeve, flexible roof bolt can play the effect of drilling rod by means of conduit, transfer torque and thrust, and be drilled into the deep of boring, and when running into resin anchoring agent or coagulating expansive cement powder stick 4 soon, will be by wedge 1 fully stirrings and solidifying of powder stick 4.The flexible body of rod installs, and unloads drilling tool 7 and sleeve thereof, and straight catheter 6 and curved conductor 5 are along with creeping into, with boring with tearing open.
In sum, deep-hole flexible super-long anchoring device for mine had both comprised flexible roof bolt and anchoring agent thereof, comprised again the annex that flexible roof bolt is used is installed: by the more piece tubulature connect form, have bent angle or a flexible conduit.Flexible roof bolt is the supporting body of anchoring, again as the facility that creep into and stir.
Fig. 3,4: show the structure of curved conductor 5, straight catheter 6, the two ends of the two have for the male and female bayonet socket that connects usefulness, and the bent angle angle of curved conductor 5 is: 90 °≤α＜180 °, make of metal, and also useable glass steel or nylon are made.
Fig. 5: the situation when showing flexible roof bolt of the present utility model and being used for roof timbering.After flexible roof bolt is loaded on boring, treat that powder stick 4 setting times reach requirement, can set up pallet 8, load onto and fastening nut 9.
Tubulature of the present utility model except above-mentioned form, can also adopt the braided steel wire flexible pipe of band plastics or rubber sleeve, and there is snap joint at every joint flexible pipe two ends.
