A hydraulic governing system is provided, the motor (2) uses hydraulic sources as power source, the position of a bit is provided with a liquid spray port, the side of the motor (2) is provided with a liquid inlet cavity (4) and a liquid return cavity (5), a pin key (8) is arranged between a spindle (7) and a motor shaft (6), a thrust bearing (9), a radial bearing (10), a seal block (11), a radial bearing (12) and a thrust bearing (13) are respectively arranged on the spindle from left to right, the central position of the spindle (7) is provided with a liquid cavity (14), one end of a liquid spray pipe (15) is communicated with the liquid return cavity (5), while the other end of the liquid spray pipe is communicated with the liquid cavity, a cavity in the front of the spindle (7) is provided with a drill block (16), and the drill chuck (3) is arranged outside the drill block. The utility model is explosion proof, and reduces dust, and increase a power by over one time than a coal electric drill. The utility model can be applied to downhole operation.
Description
Technical field
The utility model relate to a kind of be applied to underground work explosion-proof be that the explosion-proof wet type of power source is bored with the hydraulic power source.
Background technology
Electric coal drill is often adopted in underground work at present, and it mainly is made up of housing, motor, drill chuck and push system, but in use owing to produce electric spark, very easily causes gas explosion.
Summary of the invention
It is power source that the utility model provides the employing hydraulic power source, bores gas explosion when preventing underground work in the explosion-proof wet type that boring the time is sprayed water simultaneously.
The utility model mainly is made up of housing, motor, drill chuck and push system, and it is provided with hydraulic control system, and motor is power source with the hydraulic power source, is provided with mouth spray at the drill bit position.
Its motor side is provided with admission chamber and returns sap cavity, push system mainly is made up of motor drive shaft, main shaft, thrust bearing, journal bearing, be provided with pin key between main shaft and motor drive shaft, be respectively equipped with thrust bearing journal bearing sealing block on the main shaft from left to right, journal bearing and thrust bearing, alignment of shafts place is provided with sap cavity, sparge pipe one end is connected state with time sap cavity, the other end and sap cavity are connected state, and the anterior inner chamber of main shaft is provided with drill chuck, and its outside is provided with drill chuck.But be provided with throttling needle, overflow valve and admission chamber in the admission chamber and return sap cavity and be connected state.Hydraulic manifold block is below motor, and the hydraulic manifold block central longitudinal is to the tube chamber of arranging, and its left side is an admission chamber, and the right side is back sap cavity, returns sap cavity bottom and sparge pipe and is connected state, and sparge pipe is provided with the nozzle control valve.
The utility model utilizes the hydraulic power system of down-hole to be power source, the power liquid that has certain pressure makes motor shaft turn by the hydraulic control system CD-ROM drive motor, drives main shaft and rotates, it makes the drill bit in drill chuck produce very big moment of torsion under the push system effect.From liquid ejection when drill bit rotates that sap cavity ejects, reach and fall the dust effect, reduce the injury of pneumoconiosis, throttling needle in the admission chamber can be regulated the rotating speed that the fluid flow of motor into reaches governor motor, overflow valve is regulated liquid working pressure, when hydraulic power source pressure was higher than set pressure, automatic overflow was to guarantee the specified operating pressure of motor.Because the effect of hydraulic power supply, moment of torsion is big in addition, and itself and electric coal drill comparison power are enhanced about more than once, and is in light weight because the project organization compactness makes volume little, noiselessness.
