Abstract
Rotary digging rock entering drilling machine is revolved in a kind of direct circulation, it is mainly used in the hard construction in stratum, including steel wire rope, closure, mud enter pipe, connector, adpting flange, slurry pipeline, sealing ring, telescopic inner sleeve pipe, rotary digging bucket, cutter head, bearing, mud circulating pump.The problem of this development project, which overcomes traditional rotary digging, can not tackle complex working condition, and construction quality can not ensure.New invention makes construction become simple, saving construction cost.This development project can make mud cycle operation, and the effect of cooling is played to cutter head, and rotary digging bucket is more wear-resistant, the formation cut hard to underground has more preferable construction effect, mud recycles, using water wisely, can be significantly cost-effective, this invention contains bearing, convenient drilling, construction effect is more preferable, meets design needs, construction quality greatly improves, and has positive effect to improving worker's construction environment.
Description
Technical field
The present invention relates to a kind of direct circulation to revolve rotary digging rock entering drilling machine, is mainly used in science of bridge building, municipal works, discharge water conservancy project
The construction of journey, Tunnel Engineering, China Democratic National Construction Association's engineering.Because conventional drilling machine does not have mud circulating system, it is impossible to which rotary digging bucket cutter head is entered
Row cooling, can not guarantee construction quality, in view of the above-mentioned problems, researching and developing a kind of direct circulation rotation rotary digging rock entering drilling machine.
Background technology
With China's engineering construction and the development of social economy, rotary drilling rig plays more and more important in foundation pit construction
Position, this engineering method, but traditional rotary digging are often applied in building basis, the base pit engineering of industrial building and water conservancy construction engineering
Rig can not cool down to rotary digging bucket cutter head in construction, allow mud cycle operation, therefore invention one kind can make mud circulation work
The construction drill of industry, reaches that rotary digging bucket is wear-resistant, and cutter head plays the effect of cooling, and the cobble of underground and other firm hard formations are cut
It is good to cut effect, is lost time due to frequently changing cutter head in engineering, is directed at efficiency of construction and declines to a great extent, the present invention can solve this skill
Art problem.And engineering cost is saved, shortens the duration, it is ensured that underground engineering and the safety of staff.
The content of the invention
The present invention can make mud cycle operation, and the effect of cooling is played to cutter head, and rotary digging bucket is more wear-resistant, hard to underground
Hard formation cut has more preferable construction effect, and mud recycles, using water wisely, can be significantly cost-effective.The one of the present invention
Kind direct circulation rotation rotary digging rock entering drilling machine, including steel wire rope 1, closure 2, mud enter pipe 3, connector 4, adpting flange 5, mud
Delivery pipe 6, sealing ring 7, telescopic inner sleeve pipe 8, rotary digging bucket 9, cutter head 10, bearing 11, mud circulating pump 12.Steel wire rope 1 passes through
Connector 4 is connected with slurry pipeline 6, and mud reaches rotary digging bucket 9 by slurry pipeline 6, has between telescopic inner sleeve pipe 8
Sealing ring 7.Telescopic inner sleeve pipe 8 can arbitrarily adjust elongation.
Upper end closure 2 can both realize that cable guide acted on, and can prevent mud from being flowed out from top again.It should surveyed before drilling
Fixed stake position, casing is accurately buried, and ensure that casing bottom is sitting on strongly weathered sand-rock.Accurate fixed bore position, isolator
Face water, stable aperture is native and protects hole wall not collapse, and is carried out with sharp boring work；To ensure hole quality, prepared for rotary drilling rig
Drilling mud；During, instrument is carried using equipment and observes inspection, adjustment and control drilling rod perpendicularity at any time；Mended in drilling
Mud off, rig operating are filled, bit inserts the soil body, and mud does circulation temperature lowering by arrow route in accompanying drawing 1, protects knife
Head, enter from mud into pipe, reach slurry pipeline, reach rotary digging bucket from top to bottom, and flowed at rotary digging bucket cutter head
Go out, in access aperture, by mud circulating pump, make mud circulating cooling cutter head, mud integrally circulates, cooling effect and its obvious；
Rotary digging drill bit pulls rubble and silt out after destroying firm hard formation, is drilled into design hole depth, and after the completion of work, rotary drilling rig, which is extracted, to be bored
Bar shifts next hole position.
Beneficial effects of the present invention are as follows：
The rig of the present invention has sealing ring, existing damping effect, mud can be made to be circulated by design path again, prevent that mud is anti-
Stream；Mud cycle operation can be made, the effect of cooling is played to cutter head, rotary digging bucket is more wear-resistant, and the stratum hard to underground is cut
More preferable construction effect is cut；By mud circulating pump, recycle mud, using water wisely can be significantly cost-effective；This hair
It is bright more preferable containing bearing, convenient drilling, construction effect；The present invention contains connector, connecting steel wire ropes and slurry pipeline, uses work
Dynamic on-link mode (OLM), can reduce steel wire rope amount of friction, increase the service life of steel wire rope, make equipment convenient, flexible；The present invention, which contains, to stretch
Contracting inner sleeve, elongation, convenient construction can arbitrarily be adjusted according to actual use situation.
