Description
One, technical field
The utility model relates to a kind of wet type coal drilling by electric drill water supply installation, particularly relates to a kind of wet type coal drilling by electric drill injector.
Two, background technology
In the coal road tunneling process, because the restriction of operating environment, its ventilation, dustproof, system can not effectively be solved always, the control of dust is a difficult problem always, the main source of dust is that work plane can not take wet operation to cause, and solve the basic of Mine Dust and just must solve the down-hole wet operation.
Coal dust very harmful, especially at the mine that gas, coal dust explosion hazard are arranged, worker's health and Safety of Coal Mine Production are threatened bigger, the existence of mine dust, will bring certain harm to the worker is healthy:
(1) is after dust sucks human body for a long time, will cause pneumoconiosis, can't cures;
(2) be that coal dust burning and blast easily take place coal dust under certain condition, lead to bigger disaster;
(3) a large amount of coal dusts exist, and can influence worker's sight line, cause the personal safety accident easily.
Ministry of Coal Industry early hereinafter should promote the wet type coal drilling by electric drill technology at getting working face the sixth of the twelve Earthly Branches, with safety in production that guarantees the colliery and the anthraco-silicosis that reduces coal miner.But the water inlet valve for wet type coal drilling by electric drill that several water inlet valve for wet type coal drilling by electric drill that China uses at present all are each collieries gets on the job with indigenous methods and make, reasonable inadequately on the structure, because its rotatory sealing and sealing compensation do not solve, and make its application life very short, and often dismounting is relatively more difficult under coal mine, water intaking valve usually is to use the time not long, seepage just appears, even water is sprayed onto from valve and handles the workman and wait on one's body, to frequently change, result in hand cramps to working under the coal mine, and contaminated environment, that gives the staff healthyly brings serious threat, so present most of mines still use: in the formula perforating, therefore, it is long that mine working face presses for a kind of life-span, the water inlet valve for wet type coal drilling by electric drill that performance is good.
The electric coal drill side formula water supplying apparatus of Chinese patent 91217281.9, its main shaft is connected with bearing with shell, the outside of bearing screws with union (screwed)bonnet (UB, the inboard is provided with " V " type combination unreinforced seal circle of inlaying with the outer casing inner wall groove, the sidewall of shell is provided with water inlet snap joint, during work, water is sent into the aqua storage tank that is formed by sealing ring and casing groove by the water inlet joint, inlet opening on main shaft enters alignment of shafts through hole, deliver to drill bit, to realize wet drilling, have in light weight, simple in structure, easy to use, at height, characteristics such as drainage all do not appear under the low hydraulic pressure; But the outside of the bearing of the electric coal drill side formula water supplying apparatus of this patent screws with union (screwed)bonnet (UB, and is loosening easily under the working environment of often vibrations, comes off.
Three, utility model content
The purpose of this utility model is for addressing the above problem, proposing a kind of simple to operate, durable wet type coal drilling by electric drill injector.
The technical solution of the utility model is: a kind of wet type coal drilling by electric drill injector, and contain tubular shell and be installed in main shaft in the housing by two bearings, described main shaft one end is provided with the hollow drill joint, and the other end is provided with the electric coal drill electric machine joint; The inboard of two bearings is provided with two sealing rings with housing and main shaft coupling, and the aqua storage tank of main shaft is encircled in described two sealing rings and the sidewall formation at housing middle part, is provided with the water inlet joint on the sidewall at the middle part of described housing, is communicated with aqua storage tank; The end inside that described main shaft connects hollow drill is provided with the center water channel vertically, and the position of corresponding aqua storage tank radially is provided with mutually perpendicular four inlet openings on the described main shaft, is communicated with described center water channel and aqua storage tank; The outside of described two bearings is provided with " O " type circle, the oil sealing that mate with main shaft and housing successively and reaches the fixedly jump ring of oil sealing.
Described inner walls is provided with the ring-shaped groove with the sealing ring coupling.
Described inner walls is provided with the ring-shaped groove with the jump ring coupling.
Described main shaft is provided with the groove with described " O " type circle coupling.
Described water inlet joint adopts snap joint.
The beneficial effects of the utility model
1, reduces the down-hole dust, create the good working environment.
Adopt wet drilling to compare, can reach 100% depositing dust,, created the good working environment, ensured worker's life security for Safety of Coal Mine Production for the down-hole dust control by ventilation is provided convenience with the dry type perforating.After adopting wet drilling,, reduced the resistance of coal dust under the effect of press water to drilling rod because coal dust can be discharged rapidly, very light during perforating, as to need two people to operate originally electric coal drill, a present people is the energy easy manipulation just, saved man-hour greatly, and reduced working strength of workers.
2, improve perforating speed, prolong bit life.
After adopting wet drilling in addition,, reduced the time of conny, improved perforating speed greatly because pressure flow can be gone out the coal dust of intraocular automatically.Shortcomings such as easy bit freezing bar and breaking of rod bar had improved perforating speed when wet drilling had also overcome the dry type perforating, had therefore improved operating efficiency, and as can be seen, per tour can reduce circulation timei from perforating speed, improved cycling rate.When wet drilling, because the effect of press water can in time be cooled off drill bit, drill bit is not easy to wear in creeping into, and reduces the wear extent of drill bit, has prolonged bit life, for a joint consumption reduction has been created condition.
3, durable, be difficult for loosening.
Because jump ring fixedly oil sealing and bearing are adopted in the two bearings outside, under the operating mode of rotation and vibrations at a high speed, can be not loosening voluntarily as bolt, come off, reduced maintenance, can raise the efficiency equally.
