Abstract
The present invention discloses an explosion prevention hydraulic wet drill for downhole operation, which is mainly composed of a motor (2), a drill chuck (3) and a thrust system, wherein the explosion prevention hydraulic wet drill for downhole operation is provided with a hydraulic regulating system, and the motor (2) takes a hydraulic source as the power source. A drill bit is provided with a liquid spraying port, a liquid inlet cavity (4) and a liquid return cavity (5) are arranged beside the motor (2). A pin key (8) is arranged between a main shaft (7) and a motor shaft (6), and the main shaft (7) is respectively provided with a thrust bearing (9), a radial bearing (10), a sealing block (11), a radial bearing (12) and a thrust bearing (13) from left to right. The center of the main shaft (7) is provided with a liquid cavity (14). One end of a liquid spraying pipe (15) is communicated with the liquid return cavity (5), and the other end is communicated with the liquid cavity (14). An inner cavity at the front part of the main shaft (7) is provided with a drill chuck (16), and the drill chuck (3) is arranged outside the drill chuck (16). The power of the present invention in explosion prevention and dust reduction can be improved by more than one time than that of an electric coal drill. The present invention is applied to downhole operation.
Description
Technical field
The present invention relates to a kind of anti-riot hydraulic wet drill of underground work that is applied to.
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
The invention provides and adopting hydraulic power source is power source, and the wet type of spraying water simultaneously when boring is bored.
The present invention mainly is made up of housing, motor, drill chuck and push system, it is provided with hydraulic control system, motor is power source with the hydraulic power source, be provided with mouth spray at the drill bit position, motor and admission chamber and time sap cavity are connected state, and the alignment of shafts place in the push system is provided with sap cavity, and sparge pipe one end is connected state with time sap cavity, the other end and sap cavity are connected state, are provided with throttling needle and overflow valve in the admission chamber.
Described 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, journal bearing and thrust bearing on the main shaft from left to right, the anterior inner chamber of main shaft is provided with drill chuck, and its outside is provided with drill chuck.
Described 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 present invention 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 because the project organization compactness makes volume little, in light weight.
