Description

A kind of drill power head
Technical field
The utility model relates to boring mechanic technical equipment field, especially relates to a kind of drill power head.
Background technology
In present drilling operation, the unit head that be responsible for to excavate can not get in the eyelet when work, distance the going deep into along with boring between it and the drill bit; Otherwise the continuous steel pipe of disconnecting extends boring; Also to inject cooling water in the steel pipe, make the drill bit cooling, dissolving dust and methane gas.General hole all breaks into vertical angle, makes current and foreign material outside the tap of duct.During work, steel pipe and drill bit rotate together, and the greatest drawback of this conventional borehole method is:
1, steel pipe is along with the increase of drilling depth, and the steel pipe of rotation all will rotate with the interior cooling water of pipe together
2, steel pipe not only can rotate, and can produce and scratch, 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 produced is that the rotatory force overwhelming majority all consumes in the rotation of steel pipe, and resulting moment of torsion only accounts for few part on the drill bit
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 big.
The utility model content
For the frictional force that remedies above-mentioned common unit head is big, the defective that drill bit efficiency is low, the utility model proposes a kind of drill power head.
Its technical scheme does, a kind of drill power head comprises tube connector, is fixed on the power set on tube connector top, with power set transmission device that links together and the shell that is fixed on the transmission device outside and links together with power set.
Said 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, cooperates with water distribution body and stator body to form hydraulic cylinder, and the other end and transmission device are fixed together; The steel ball piston is fixedly mounted on also can be along the radial motion of water vat inwall on the rotor block.
Said tube connector also comprises water inlet pipe, and water inlet pipe is communicated with the water distribution body.
Said 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 the shell, and the enclosure space sealing is lived.
Said power transmission shaft inside is drilled with the water outlet pore, also has breach on the sidewall of top, and the water outlet pore is connected with breach.
On the water distribution body, also have exhalant canal, exhalant canal is connected with the water outlet pore.
The utility model is compared with traditional unit head, and following benefit is arranged:
1. drill bit directly is contained on the unit head output shaft, need not drive the miscellaneous part acting, has improved the operating efficiency of unit head;
2. when work, unit head is along with drill bit gets in the 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. feed press water in the steel pipe,, make the unit head output shaft drive drill bit and rotate together before this as the working media of unit head; Hole; Flow to drill bit from the unit head opposite side then, supply drill bit, cooling, lubricated, dissolving dust, absorb residual methane gas after; Outside the hole wall tap, no longer reclaim.
This bore mode of the utility model is concerning the conventional borehole mode; Be a kind of change of essence, the energy has been practiced thrift in revolutionary invention greatly, has accelerated penetration rate; Reduced the boring cost with water especially for oil; And having prolonged the application life of unit head, also reduced labor intensity of operating personnel, is a kind of initiative at home.
Description of drawings
Fig. 1 is the structure cross-sectional schematic of a kind of embodiment of the utility model;
Among the 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 utility model is further specified.
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, with power set transmission device 3 that links together and the shell 4 that is fixed on the transmission device outside and links together with power set.Said 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, cooperates with water distribution body and stator body to form hydraulic cylinder 25, and the other end and transmission device are fixed together; The steel ball piston is fixedly mounted on also can be along the radial motion of hydraulic cylinder inwall on the rotor block.Said tube connector also comprises water inlet pipe 11, and water inlet pipe is communicated with the water distribution body.Said 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 the shell, and the enclosure space sealing is lived.Said power transmission shaft internal fixation has water outlet pore 33, also has breach 34 on the sidewall of top, and the water outlet pore is connected with breach.On the water distribution body, also have exhalant canal 26, exhalant canal is connected with the water outlet pore.
Present embodiment is fixed to drill bit 5 on the power transmission shaft in work, and the water inlet pipe through tube connector feeds water under high pressure to the water distribution body, and water under high pressure is driven plunger in hydraulic cylinder, and then drives the rotor block motion.Water under high pressure drives rotor block and rotates the back by the water outlet pore that is got into power transmission shaft again by the exhalant canal of water distribution body, and flows out unit head through 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 the shell, prevents that sewage from flowing into unit head.
The utility model water replaces the hydraulic oil in the conventional hydraulic unit head, behind the water-driven unit head, can also be unit head and drill bit cooling and cleaning 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, the protection environment is practiced thrift cost.
The above; Preferable case study on implementation for the utility model; Be not that the utility model is done any restriction; Everyly any simple modification that above embodiment did, change and equivalent structure are changed, all still belong in the protection domain of the utility model technical scheme according to the utility model technical spirit.
