Various rigs are widely used in engineering explosion hole drills such as the cubic metre of earth and stone cutter operation of metallurgy, coal, building materials, railway, highway, mine, construction of hydropower facilities, civil building, national defense construction.But at present a lot of building sites also at the operating type that adopts artificial hired roughneck's pneumatic pick boring, little, the depth as shallow of its bore diameter, operating efficiency is low, energy consumption is high, noise height, dust are big, contaminated environment.Operating personnel's condition of work is abominable, exposes to the sun and rain, and vibrations are big, and the white finger that is easy to get is sick, and dust is big, the anthraco-silicosis that is easy to get, noise height, hearing damage.Because serious to the healthy infringement of operating personnel, labour intensity is big, and have very big potential safety hazard, operating personnel are very difficult to be engaged, and this working method has also been prohibited in some place.So the cutting rig of efficient, energy-saving and environmental protection, safety is used more and more widely, and the rotary motive power head is the vitals of cutting rig work, the quality of its performance is the performance and the operating efficiency of directly decision cutting rig.
Summary of the invention
Technical problem to be solved by this invention provides the cutting rig rotary motive power head that a kind of moment of torsion is big, rotating speed is high, rate of penetration is fast, noise is little, simple in structure.
In order to solve the problems of the technologies described above, cutting rig rotary motive power head provided by the invention, comprise main shaft, described main shaft is provided with the hollow appendix, described shaft seal is rotatably installed on the reduction box, described main shaft is equipped with the gear wheel that is in the described reduction box, is provided with the pinion with described gear wheel engaged transmission in described reduction box, hydraulic motor and described hydraulic motor output shaft is installed on the described reduction box is connected with described pinion drive.
The installation shaft two ends of described pinion are installed on the described reduction box by cylinder roller bearing, and described main shaft is installed on the described reduction box by taper roll bearing.
Two of described main shaft all adopts two sealing rings to carry out double-layer seal.
Described reduction box is provided with suspension ring.
Described reduction box is made up of deceleration box and gear box cover, and described hydraulic motor is installed on the described gear box cover, and the tail end of described main shaft is on the described gear box cover.
Adopt the cutting rig rotary motive power head of technique scheme, simple in structure, easy to manufacture, easy for installation.Be installed in during use on the propelling slide of cutting drilling quarry bar, rig is when boring, rotary motive power head driving drilling rod and cut drill are rotated at a high speed and are crept into, and compressed air is blown out by the drill bit periphery through dynamic head main spindle and drilling rod center, outside the rock slag tap under boring.
The hydraulic motor volume is little, in light weight, and driving torque is big, the rotating speed height.
Main shaft is provided with the hollow appendix, helps compressed air by carrying out deslagging, and seal style is simple and reliable.Main shaft two all adopts two sealing rings to carry out double-layer seal, can effectively prevent the leakage of compressed air and lubrication oil.
The gear reduction noise is little, efficient is high, simple in structure, handling ease, reliability height.
Cylinder roller bearing and taper roll bearing rotating speed height, bearing capacity is big.
The pump nozzle apply oil is convenient, helps the lubricated of gear and bearing, reduces wearing and tearing and heating.
The configuration suspension ring make installation, easy to maintenance, and are safe.
The utlity model has following tangible advantage:
(1), moment of torsion is big, the rotating speed height, rate of penetration is fast.
(2), noise is little, efficient is high, simple in structure, the reliability height.
(3), main shaft makes hollow type, seal style is simple and reliable, can effectively prevent the leakage of compressed air and lubrication oil.
(4), greasy property is good, can reduce wearing and tearing and heating.
(5), installation, easy to maintenance, safe.
In sum, the present invention be that a kind of moment of torsion is big, rotating speed is high, rate of penetration is fast, noise is little, simple in structure, greasy property good, can reduce wearing and tearing and heating, installation, easy to maintenance, safe cutting rig rotary motive power head.
