Abstract
The invention discloses a hydraulic slip, which comprises a casing, a lifting mechanism and four identical slip assemblies, wherein the four identical slip assemblies are arranged inside the casing, the casing comprises a first case and a second case, and the lifting mechanism comprises a balance beam, a hydraulic cylinder and a slip support frame connecting rod. The hydraulic slip is characterized in that a first lug boss and a second lug boss are respectively arranged on the outer wall of the first case and the outer wall of the second case, and a stroke switch is arranged between the balance beam and the casing. The hydraulic slip has the beneficial effects that the height of the whole machine is low, the hydraulic slip is arranged in a well table turntable in the use process, the derrick operation space is saved, in addition, the torque being 35000ft.lbs can be born to the maximum degree, users do not need to use back-up tongs any more, the use is convenient, and the clamping and the holding are safe and reliable.
Description
Technical field
The present invention relates to a kind of slip system, particularly relate to a kind of hydraulic pressure pipe slips.
Background technology
Drilling slip is that its inwall has many steel teeth at the outstanding special tool of holding drilling tool of well head.The instrument that holds sleeve pipe in existing oil, natural gas operation mainly contains: 1, manual casing slip, and multiple-piece structure, this slips volume is large, and weight is large, and labor strength is large, and inefficiency and safety are not high; 2, Pneumatic slip type sleeve elevator, can realize the automatic lifting of slips body, but this device volume is huge, and is arranged on rotating disk top, makes complete machine height distance plane of rotor disc higher, to hydraulic tongs, uses and makes troubles; 3, air operated slips, can realize slips automatic lifting, and is arranged in rotating disk, has saved space, but can not bearing torque.
Summary of the invention
The object of the invention is to solve the defect that existing slip system can not bear moment of torsion, provide a kind of rational in infrastructure, lifting force is large, holds scope wide, and hydraulic power slip safe and reliable, easy and simple to handle that can bearing torque solves the problems referred to above.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of hydraulic pressure pipe slips, comprise: housing, hoisting mechanism and be arranged on four identical slip assemblies of enclosure interior, described housing comprises the first shell, second housing, described hoisting mechanism comprises equalizer bar, hydraulic cylinder and slips rack rod, it is characterized in that, on the outer wall of described the first shell and second housing, be respectively equipped with the first boss and the second boss, between described equalizer bar and housing, travel switch be installed.
In the present invention, described the first shell is fixedly connected with by two joint pins with second housing.
In the present invention, described slip assemblies comprises slips body and dental lamina.
In the present invention, described travel switch is rolling wheel type travel switch.
In the present invention, the top of described housing is provided with top guide strip, and the bottom of housing is provided with bottom guide ring.
Beneficial effect of the present invention is mainly reflected in: complete machine height is low, is arranged in raised platform around a well rotating disk during use, has saved derrick operating space, and maximum can be carried the moment of torsion that can bear 35000ftlbs, user can not re-use back-up tong, easy to use, holds safety, reliable.
Accompanying drawing explanation
Fig. 1 is top view of the present invention;
Fig. 2 is the sectional drawing of 1/4 part of the present invention.
The specific embodiment
Because hydraulic pressure pipe slips of the present invention inside is comprised of identical four parts, therefore, the part of only take in present embodiment wherein describes as example, referring to Fig. 1 and Fig. 2, the first shell 110 is fixedly connected with 220 by two joint pins 210 with second housing 120, form housing, be the first roof beam structure 310 and the mutual chimeric formation equalizer bar of the second roof beam structure 320 of U-shaped structure, in forming, equalizer bar and housing connect relation, the outer wall of the first shell 110 is provided with the first boss 111, the outer wall of second housing 120 is provided with the second boss 121, between the inwall of the first shell 110 and the first roof beam structure 310, be provided with travel switch 400, between the inwall of second housing 120 and the second roof beam structure 320, be provided with hydraulic control valve 500.The top of housing is also provided with top guide strip 600, and bottom is also provided with bottom guide ring 900, and bottom guide ring 900 mainly play the guiding role, and guarantees that tubing string is placed in the middle, equalizer bar, hydraulic cylinder 700 forms hoisting mechanism together with slips rack rod 1100, slips body 800 and dental lamina 810 form slip assemblies, in drilling well casing job process, sleeve pipe holds by slip assemblies, slips body 800 is connected with the first roof beam structure 310 by slips rack rod 1100, the piston rod of hydraulic cylinder 700 passes through bolt, nut is fixedly connected with the first roof beam structure 310, hydraulic cylinder 700 piston rod movements drive equalizer bar to move up and down like this, equalizer bar drives again slips rack rod 1100 to move up and down, slips rack rod 1100 drives again slip assemblies to move up and down, thereby realize slip assemblies rising and unclamp tubing string, slip assemblies falls the function that holds tubing string, and, when slip assemblies is transferred to behind the contact 410 of contacting travel switch 400, hydraulic valve 500 is started working, hydraulic cylinder 700 pressure increase gradually, to hold tubing string more firm for slip assemblies like this.
In sum, it is only preferred embodiment of the present invention, not be used for limiting scope of the invention process, all equalizations of doing according to the shape described in the claims in the present invention scope, structure, feature and spirit change and modify, and all should be included within the scope of claim of the present invention.
