Description
Technical field
A kind of mining high-voltage water of the utility model relates to the device of surrounding rock supporting in a kind of mine construction from boring grouted anchor bar, belongs to the plant equipment field.Be particularly related to a kind of use water under high pressure drill bit, can carry out fast that anchor pole is fixed and carry out supporting at the country rock that contains hard geology, can be through improve the device of supporting anchor-hold to the direct slip casting of anchor pole.
Background technology
The kind of anchor pole is many at present; Also a lot of with matching used jumbolter type of anchor pole and model; The result of use of anchor pole depends on the performance of jumbolter very greatly, because the narrow particular job condition of mine, the result of use of a lot of anchor poles does not reach the requirement of expection far away.Though the efficient that has is high, be not suitable for the narrow and small operating condition of mine.Cooperate drill carriage formula waste of flax rig to use such as anchor pole, though drill carriage formula jumbolter efficient is high, safety is good, and the anchor pole drill carriage need take certain space, and the condition of mine is not suitable for the use of anchor pole drill carriage.Though what have is fit to the narrow and small operating condition of mine, efficiency of operation is too low not to reach requirement.Cooperate the monomer-type jumbolter like anchor pole, although monomer-type jumbolter light weight, volume are little, monomer-type jumbolter efficient is relatively low, can't reach requirement.
Summary of the invention
In order to improve above-mentioned situation; A kind of mining high-voltage water of the utility model provides under a kind of mine the equipment that country rock is carried out supporting from boring grouted anchor bar; Can be fit to narrow and small and easy operating condition under the mine, improve the supporting operating efficiency, improve the anchor-hold after first anchor-hold and the supporting effectively.
A kind of mining high-voltage water of the utility model is achieved in that from boring grouted anchor bar a kind of mining high-voltage water of the utility model bores grouted anchor bar certainly and is made up of anchor head, shaft and bearing three parts.Anchor head is made up of water under high pressure outlet, high pressure water transport pipe and drill bit.High pressure water transport pipe places the inside of drill bit, and the water under high pressure outlet places the front end of drill bit.Shaft is made up of anchor bar body, high pressure water transport pipe, screw thread and grout outlet.Thread helix is wrapped in the anchor bar body surface, the both sides up and down of anchor bar body and row's grout outlet is each side arranged, and high pressure water transport pipe is placed at anchor bar body inside, and anchor bar body is a hollow.The front end of anchor bar body is connected with the bottom of drill bit.Bearing is made up of stop grouting plug, arch backing plate and ball-type nut.Stop grouting plug connects the arch backing plate, and spherical nut fixedly arch backing plate is connected with stop grouting plug.Stop grouting plug places the rear end of anchor bar body.
During use, be tightened in the drill bit rotation on the anchor bar body earlier, the stop grouting plug rotation is tightened in the bottom of anchor bar body, the arch backing plate of and then screwing in the stop grouting plug back, and the spherical nut of behind the arch backing plate, screwing on is at last locked.Then anchor pole is placed on the common bolt rig, high pressure water transport pipe reconnects the high pressure water valve.During operation, open high pressure water valve and jumbolter and hole.Anchor pole is through the spiral thread rotary drilling, and water under high pressure is beaten on the rock of boring, punctures rock rapidly, and the arch backing plate blocks the dust that boring causes.Get to desired location when anchor pole, stop jumbolter and rotate, close the high pressure water valve.After the completion, carry out slip casting through the anchor bar body rear end to the anchor bar body body cavity, mud flows out with rock around the anchor pole from grout outlet and contacts, and stop grouting plug prevents that too much mud is outside the anchor bar body tap hole.Carry out the anchor pole locking at last.Can excavate down one deck, reach the purpose of in mine construction, carrying out surrounding rock supporting fast.
Beneficial effect
One, simple in structure, the convenient use.
Two, with low cost, be easy to promote.
Three, can adapt to the narrow and small operating condition of mine, increase work efficiency.

Accompanying drawing 2 bores the sectional structure chart of grouted anchor bar certainly for a kind of mining high-voltage water of utility model
In the accompanying drawing
Wherein part is: arch backing plate (1), stop grouting plug (2), anchor bar body (3), drill bit (4), water under high pressure outlet (5), screw thread (6), spherical nut (7), grout outlet (8), high pressure water transport pipe (9) (10)
The specific embodiment:
A kind of mining high-voltage water of the utility model is achieved in that by anchor head, shaft, bearing three parts and forms that anchor head is by drill bit (4), water under high pressure outlet (5) and high pressure water transport pipe (10) formation from boring grouted anchor bar.High pressure water transport pipe (10) is in the inside of drill bit (4), and an end of high pressure water transport pipe (10) is water under high pressure outlet (5), when drilling, can export (5) from water under high pressure and penetrate water under high pressure, improves the efficient of drilling.The bottom of drill bit (4) is connected with anchor bar body (3).Shaft comprises anchor bar body (3), high pressure water transport pipe (9) and grout outlet (8), and the surperficial spiral of anchor bar body (3) is wound with screw thread (6), helps anchor pole from boring.And anchor bar body (3) is a hollow, is used for slip casting, and mud flows out anchor bar body and contacts with casing through grout outlet (8), makes supporting more tight.High pressure water transport pipe (9) can be carried water under high pressure.The other end of anchor bar body (3) connects stop grouting plug (2).Bearing is made up of stop grouting plug (2), arch backing plate (1) and spherical nut (7).Stop grouting plug (2) connects arch backing plate (1); Arch backing plate (1) back connects spherical nut (6); Stop grouting plug (2) is used to prevent mud (3) outflow from the country rock body along anchor bar body of slip casting; Arch backing plate (1) makes the anchor pole external energy paste country rock more closely, and spherical nut (6) then can make dome shaped pad plate (1) and stop grouting plug (2) tighten.As long as drill bit (4) rotation is tightened on the anchor bar body (3), stop grouting plug (2) rotation is tightened in the bottom of anchor bar body (3), the arch backing plate (1) of and then screwing in stop grouting plug (3) back; The spherical nut (7) of behind arch backing plate (1), screwing on is at last locked, and then anchor pole is placed on the common bolt rig; High pressure water valve in high pressure water transport pipe (8) (9) connection is opened high pressure water valve and jumbolter and is holed, and boring is carried out slip casting after accomplishing; Carry out the anchor pole locking at last; Supporting is promptly accomplished, and can excavate down one deck, has reached the purpose of in mine construction, carrying out surrounding rock supporting fast.
