Abstract
A power head with a damping device is applied to a drilling rig for the oil exploration. The utility model is characterized in that a circular end cover is fixed at the lower part of a sealing head through bolts; a central pipe is fixed in the central hole of the end cover; the outside wall of the central pipe is provided with a spline; the outer part of the central pipe is sleeved with the spring; the retaining sleeve of the circular spring is mounted between the spring and the end cover; a spline sleeve is sleeved at the lower end of the central pipe. The spline sleeve is fixed on the lower joint component through the bolts; the biggest journey of the spline sleeve is retained at the lower end of the central pipe by a round nut, a retaining gasket and a locking nut; the top end of the lower joint component is inserted into the inner hole at the lower end of the central pipe. The utility model has the effects that the shocking force from the drilling tool is reduced through the damping capacity of the spring; the service life of the connection components of the drilling rig is improved; and the reliability of the moving piece is enhanced.
Description
Technical field
The utility model relates to the oil exploration rig, and particularly the unit head of rig is that a kind of drill power head top increases damping device, and buffering is from the shaking force of drilling tool.
Background technology
In petroleum geology exploration, when boring man-made explosion big gun hole, rig is main exploring equipment, and unit head is the vitals of rig.The effect of unit head performance has: the one, drive the drilling tool rotation, and energy is transferred to downhole drill bit, reach the purpose of the drilling well of breaking ground; The 2nd, flushing fluid is transported to the drilling rod center, realize the purpose of circulation well cleanup eliminating landwaste.From the transfer route of power, the vibrations that drilling tool produces at first are delivered to unit head, pass to derrick by unit head again, until complete machine.See that thus unit head plays a part to form a connecting link in the transmittance process of power.When boring man-made explosion big gun hole, vibrations make that the unit head connector is loosening, fatiguability damages, and the moving component reliability reduces.
At present, portable drilling rig unit head commonly used does not have damping device, generally adopts lower contact assembly, seal head and housing to be linked in sequence, and uses bolt.Also do not cushion the precedent of the impact force that produces in the drilling process by band damping device unit head.
The utility model content
The purpose of this utility model is: a kind of unit head with damping device is provided, can cushions the shaking force that brings owing to the drilling tool vibrations in the drilling process, guarantee that the connection between each parts of complete machine is reliable, increase the service life.
The technical solution adopted in the utility model is: the unit head of band damping device mainly is made up of lower contact assembly, seal head and housing.Be connected with the flushing fluid inlet tube on the seal head, seal head is connected lower part of frame, it is characterized in that: adopt bolt that an annular end cap is arranged in the bottom of seal head.Be fixed with central tube in the end cap central bore.The outer wall of central tube has spline.The outside of central tube is with spring.Ring-spring stop cover is arranged between spring and the end cap.Lower end at central tube is with spline housing.Adopt bolt that spline housing and lower contact assembly are fixed together.On the external screw thread of the lower end of central tube round nut, floor clip and locknut are arranged, round nut, floor clip and locknut can limit the range with spline housing.Insert in the lower end endoporus of central tube on the top of lower contact assembly.
In order to improve sealing, reduce the loss of flushing fluid, between the top of lower contact assembly outer wall and central tube inwall, sealing ring is arranged.
Described spring is a spiral compression spring.
It is the moment of torsion of housing to be passed to the lower contact assembly that central tube adopts the purpose of spline; And spline housing can slide up and down along spline, eliminates or slows down the shaking force that the vibrations of drilling tool in the drilling process bring.
The beneficial effects of the utility model: the unit head of the utility model band damping can pass through spring shock absorption, and the shaking force from drilling tool is weakened, thereby has improved the application life of rig connector, and the movement parts reliability is strengthened.
Description of drawings
Fig. 1 is the power head structure generalized section of the utility model band damping device.
Fig. 2 is the local amplification profile schematic diagram of Fig. 1.
Among the figure, 1. lower contact assembly, 2. seal head, 3. housing, 4. end cap, 5. spring stop cover, 6. spring, 7. central tube (wounded in the battle key), 8. spline housing, 9. round nut, 10. stop washer, 11. locknuts.
The specific embodiment
Embodiment 1: the unit head of band damping device is to improve to form on the architecture basics of original unit head.
Consult Fig. 1.The side of seal head 2 is connected with a flushing fluid inlet tube, and seal head 2 bolts are connected the bottom of housing 3.
Consult Fig. 2.Adopt bolt that an annular end cap 4 is arranged in the bottom of seal head 2.
Consult Fig. 1.Be fixed with a central tube 7 in end cap 4 centre bores.The outer wall of central tube 7 has spline, and spline can be delivered to the moment of torsion of housing 1 lower contact assembly 1.Central tube 7 internal diameters are 35 millimeters.The outside of central tube 7 is with a spiral compression spring 6.Ring-spring stop cover 5 is arranged between spring 6 and the end cap 4.Be with inner spline housing 8 in the lower end of central tube 7.Adopt bolt that spline housing 8 and lower contact assembly 1 are fixed together.Round nut 9, floor clip 10 and locknut 11 are arranged on the external screw thread of the lower end of central tube 7, and round nut 9, floor clip 10 and locknut 11 can limit the range with spline housing 8.Insert in the lower end endoporus of central tube 7 on the top of lower contact assembly 1.Between the top of lower contact assembly 1 outer wall and central tube 7 inwalls, three road rubber seal are arranged.When drilling tool in the drilling process produced vibrations, spline housing 8 can slide up and down along spline, eliminated or slowed down the shaking force that the drilling tool vibrations bring in the drilling process.
