Compared with the traditional drilling mode, the drilling mode disclosed by the invention is a fundamental change, revolutionary pioneering work greatly saves energy, drilling speed is quickened, drilling cost is lowered by replacing oil with water, the service life of the power head is prolonged, the labor intensity of operation personnel is also lowered, and the drilling rig power head is an initiate in China.
Description
Technical field
The present invention relates to boring mechanic technical equipment field, especially relate to a kind of drill power head.
Background technology
In current drilling operation, the unit head of being responsible for excavating time can not enter in eyelet in work, distance the going deep into along with boring between it and drill bit, otherwise the continuous steel pipe of disconnecting extends boring, in steel pipe, also to inject cooling water, make drill bit cooling, dissolve dust and methane gas.General hole all breaks into vertical angle, makes current and foreign material outside the tap of duct.When work, steel pipe rotates together with drill bit, and the greatest drawback of this conventional borehole method is:
1, steel pipe is along with the increase of drilling depth, the steel pipe of rotation and cooling water in pipe all will together with rotate
2, steel pipe not only can rotate, and can produce and perturb, and the frictional force of tube wall and hole wall is constantly increased with the increase of drilling depth
3, the moment of torsion that unit head produces is that the rotatory force overwhelming majority all consumes in the rotation of steel pipe, and the moment of torsion obtaining on drill bit only accounts for few part
4, consequently production efficiency reduces along with the increase of drilling depth, has finally limited drilling depth, because energy all consumes in the rotation of steel pipe, the waste of energy is very large.
Summary of the invention
Large in order to make up the frictional force of above-mentioned common unit head, the defect that drill bit efficiency is low, the present invention proposes a kind of drill power head.
Its technical scheme is, a kind of drill power head comprises tube connector, is fixed on the power set on tube connector top, the transmission device linking together with power set and the shell that is fixed on transmission device outside and links together with power set.
Described power set are hydraulic motor structure, also comprise water distribution body, stator body, rotor block and steel ball piston, and wherein, water distribution body one end and tube connector are fixed, and the other end and stator body are fixed together; Rotor block one end extends into stator body inside, coordinates form hydraulic cylinder with water distribution body and stator body, and the other end and transmission device are fixed together; Steel ball piston is fixedly mounted on also can be along the radial motion of water vat inwall on rotor block.
Described tube connector also comprises water inlet pipe, and water inlet pipe is communicated with water distribution body.
Described transmission device comprises power transmission shaft and black box, and power transmission shaft one end connects rotor block, and the other end is connected with drill bit, and black box is fixed between power transmission shaft and shell, and enclosure space sealing is lived.
Described power transmission shaft inside is drilled with outlet pipe hole, also has breach on the sidewall of top, and water outlet pore is connected with breach.
On water distribution body, also have exhalant canal, exhalant canal is connected with water outlet pore.
The present invention, compared with traditional unit head, has following benefit:
1. drill bit is directly contained on power head output shaft, need not drive miscellaneous part acting, has improved the operating efficiency of unit head;
2. in work time,, unit head is along with drill bit enters in sky together, along with drilling depth be increased in the unit head back steel pipe that continues, steel pipe does not rotate, and has avoided the frictional resistance of steel pipe and borehole sidewall;
3. in steel pipe, pass into press water, before this as the working media of unit head, make power head output shaft drive drill bit to rotate together, hole, then flow to drill bit from unit head opposite side, for drill bit, cooling, lubricate, dissolve dust, absorb after residual methane gas, outside hole wall tap, no longer reclaim.
This bore mode of the present invention is concerning conventional borehole mode, it is a kind of change of essence, the energy has been saved in revolutionary invention greatly, accelerate penetration rate, reduce especially boring cost with water for oil, and having extended the application life of unit head, also reduced operating personnel's labour intensity, is a kind of pioneering at home.
Accompanying drawing explanation
Fig. 1 is the structure cross-sectional schematic of a kind of embodiment of the present invention;
In figure, 1, tube connector; 11, water inlet pipe; 2, power set; 21, water distribution body; 22, stator body; 23, rotor block; 24, steel ball piston; 25, hydraulic cylinder; 26, exhalant canal; 3, transmission device; 31, power transmission shaft; 32, black box; 33, water outlet pore; 34, breach; 4, shell; 5, drill bit.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
With reference to Fig. 1, a kind of drill power head, comprises tube connector 1, is fixed on the power set 2 on tube connector top, the transmission device 3 linking together with power set and the shell 4 that is fixed on transmission device outside and links together with power set.Described power set are hydraulic motor structure, also comprise water distribution body 21, stator body 22, rotor block 23 and steel ball piston 24, and wherein, water distribution body one end and tube connector are fixed, and the other end and stator body are fixed together; Rotor block one end extends into stator body inside, coordinates form hydraulic cylinder 25 with water distribution body and stator body, and the other end and transmission device are fixed together; Steel ball piston is fixedly mounted on also can be along the radial motion of hydraulic cylinder inwall on rotor block.Described tube connector also comprises water inlet pipe 11, and water inlet pipe is communicated with water distribution body.Described transmission device comprises power transmission shaft 31 and black box 32, and power transmission shaft one end connects rotor block, and the other end is connected with drill bit, and black box is fixed between power transmission shaft and shell, and enclosure space sealing is lived.Described power transmission shaft inside is fixed with water outlet pore 33, also has breach 34 on the sidewall of top, and water outlet pore is connected with breach.On water distribution body, also have exhalant canal 26, exhalant canal is connected with water outlet pore.
The present embodiment, in work, is fixed to drill bit 5 on power transmission shaft, passes into water under high pressure by the water inlet pipe of tube connector to water distribution body, and water under high pressure is driven plunger in hydraulic cylinder, and then the motion of rotor driven body.After driving rotor block to rotate, water under high pressure by entered again the water outlet pore of power transmission shaft by the exhalant canal of water distribution body, and flows out unit head by breach.The water that flows out unit head is that drill bit and unit head are lowered the temperature, and black box seals the space between power transmission shaft and shell, prevents that sewage from flowing into unit head.
Water of the present invention replaces the hydraulic oil in conventional hydraulic unit head, after water-driven unit head, can also lower the temperature and clean drill bit for unit head and drill bit, has improved the utilization ratio of water, has reduced the pollution that drives unit head with hydraulic oil.And this product with water for oil, reduced job costs, improved the utilization ratio of water, protection of the environment, cost-saving.
The above; for better case study on implementation of the present invention; not the present invention is imposed any restrictions, every any simple modification of above embodiment being done according to the technology of the present invention essence, change and equivalent structure change, and all still belong in the protection domain of technical solution of the present invention.
