Description
Technical field
The utility model relates to a kind of hydraulic rotating pipe clamping device.
Background technology
Fault of oil well, all will carry out workover treatment by workover rig.During well workover, by the clamp be contained on the top rail of workover rig, oil pipe is blocked, oil pipe can only move up and down with the top rail of workover rig, and can not rotate, when cannot complete well workover, oil pipe needs the technological requirement can rotated and can pump, only have after oil well is bled off pressure and could construct, workover treatment efficiency is reduced greatly.
Utility model content
The technical problems to be solved in the utility model is for above-mentioned defect, provides a kind of hydraulic rotating pipe clamping device, after oil pipe blocks by this pipe clamping device, oil pipe can be made to rotate oil pipe can be made again to pump with the top rail of workover rig.
For solving the problems of the technologies described above, the utility model provides a kind of hydraulic rotating pipe clamping device of following structure, its design feature is: comprise housing, the roof of housing is provided with installing hole, the diapire of housing is provided with lower installing hole, be provided with in housing and be contained in installing hole and lower installing hole and rotating central tube, form closed oil pocket between central tube and housing, housing is provided with the oilhole be communicated with oil pocket; The tube wall of central tube is provided with two piston holes be oppositely arranged, and described piston hole is built with piston, and the inner of described piston is connected with the slips embracing oil pipe for card; Described piston is connected with resetting-mechanism.
Described resetting-mechanism is the arc-shaped leaf spring being positioned at oil pocket, and the two ends of arc-shaped leaf spring are connected with the outer end of two-piston respectively.
Described arc-shaped leaf spring is two that are oppositely arranged.
Described housing is two body structures be made up of upper shell and lower house, together with upper shell is bolted with lower house.
Described slips is provided with many detent projection.
Described central tube is connected in upper installing hole and lower installing hole by the taper roll bearing that two are oppositely arranged.
The hydraulic rotating pipe clamping device of said structure, can be connected on the top rail of workover rig by its housing, oil pipe passes from its central tube, sent in oil pocket by the oilhole of hydraulic oil on housing by oil-servicing facilities, hydraulic oil driven plunger is to center in-pipe and embraced by tubing clamp by slips.Because central tube is rotatable, therefore also can realize the rotation of oil pipe, and oil pipe can be ordered about when hydraulic rotating pipe clamping device pumps with the top rail of workover rig and pump.
In sum, the utility model has the advantage of: structure is simple, easy to use, can make the rotary motion of oil pipe and synchronous realization that pump, its application makes well workover with pressure be achieved, and can greatly improve well workover speed.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view along A-A line in Fig. 1.
Detailed description of the invention
As depicted in figs. 1 and 2, hydraulic rotating pipe clamping device comprises housing 1, and housing 1 is made up of upper shell 101 and lower house 102, and upper shell 101 is provided with sealing mat 12 together with being bolted with lower house 102 between upper shell 101 and lower house 102.On the roof of housing 1, namely the end face of upper shell 101 is provided with installing hole 2, and on the diapire of housing 1, namely the bottom surface of lower house 102 is provided with lower installing hole 3; Upper installing hole 2 and lower installing hole 3 are outer little interior large stepped hole.Be provided with central tube 4 in housing 1, the top of central tube 4 is connected to by a taper roll bearing 11 in the macropore of upper installing hole 2, and the bottom of central tube 4 is connected to by another taper roll bearing 11 in the macropore of lower installing hole 3; The sealing ring 13 of the hole wall sealing for central tube 4 and two apertures is all housed in the aperture of upper installing hole 2 and lower installing hole 3.Form closed oil pocket 5 between central tube 4 and housing 1, housing 1 is provided with the oilhole 6 be communicated with oil pocket 5; The tube wall of central tube 4 is provided with two piston holes be oppositely arranged, and described piston hole is built with piston 7, and the inner of two pistons 7 is respectively connected with the slips 8 embracing oil pipe for card; Described slips 8 is provided with many detent projection 10, and it is more firm that detent projection 10 can increase that slips 8 and the frictional force of oil pipe is beneficial to that tubing clamp embraces by slips 8.In oil pocket 5, supply hydraulic oil can order about two pistons 7 and move to the inside of central tube 4 thus the oil pipe (not shown) card through central tube 4 is embraced, even if embrace outside movement of two pistons 7 to releasing to the card of oil pipe to return original position again, then ordering about of resetting-mechanism is needed to complete.Described resetting-mechanism is be positioned at relative separation central tube 4 both sides of two arc-shaped leaf springs, 9, two arc-shaped leaf springs 9 of oil pocket 5; The two ends of described arc-shaped leaf spring 9 are connected with the outer end of two-piston 7 respectively, and namely one end is connected with piston 7 outer end, the other end is connected with the outer end of another piston 7.After the pressure contact of the hydraulic oil in oil pocket 5, two-piston 7 outwards can move and return under the driving of two arc-shaped leaf springs 9.
