Description
The present invention relates to a kind of hydraulic slip system with three-direction slip, belong to the slip system class of in oil drilling, workover treatment, using.
In the round trip of oil field well workover, use two elevators to repeat loading and unloading and carrying in turn usually by two people, labour intensity is big, and efficient is low.Chinese patent CN2034195U discloses a kind of composite lever formula seat card device, comprises slips body, chassis, composite lever mechanism, balanced controls, and it only needs the one man operation, saves manpower.The weak point of this device is still to follow manual operations, unsafe factor still exists, particularly in tripping operation, must with crane oil pipe upwards be mentioned earlier, simultaneously make slips unclamp oil pipe fast, the power of upwards carrying can not be too big, can not be too little, the synchronism of this operation is difficult to grasp, and can not adapt to rapidly, continuously, the requirement of mechanized.In addition, when unloading screw thread on oil pipe adopts Power Tong, generally also need by manually beating back-up tong, circumferentially tightening oil pipe bearing reaction torque, this work had not only been required great effort time-consuming but also dangerous.
The object of the present invention is to provide a kind of hydraulic slip system with three-direction slip, adopt the hydraulic control mechanized operation, from axially, radially, simultaneously oil pipe is tightened on circumferential three directions, and guarantee that crane upwards proposes the operation that oil pipe and slips unclamp oil pipe and carry out synchronously, it is time saving and energy saving that operation is saved trouble, and increases work efficiency and safety.
The objective of the invention is to reach as follows: a kind of hydraulic slip system with three-direction slip comprises base, loam cake, side cover, its centre is provided with 3～6 dental laminas, and oil pipe is held tightly, and dental lamina is fixed on the dental lamina seat, the medial surface of dental lamina seat by dovetail groove and jaw movingly, the medial surface that jaw has dovetail groove is an inclined-plane, and its gradient preferably adopted international 1: 3, and this inclined-plane makes the past more downslide of oil pipe, the dental lamina card must be tight more, thereby have auto-lock function.There is a groove at the lateral surface middle part of jaw, in groove, install a roller by a bearing pin, the outer rim of roller contacts with the inwall of a rotary body, for guaranteeing the two closely contact all the time, an extension spring is being set respectively between the outer rim of jaw and base and between jaw and the side cover.
Be the optional position that guarantees no matter roller is in the rotary body inwall, the suffered tangential force of captured oil pipe is a predetermined constant with the ratio of radial load, promptly cuts through than constant, and the rotary body inwall is designed to wait lift angle helical curved surface.Fluted in the rotary body bottom, realize movingly with the protruding track on the base.Also be provided with the jaw seat on base, jaw seat and base are connected as a single entity, and the jaw seat plays the restriction jaw and circumferentially moves.On the rotary body outer wall, be fixed with swing handle, the piston rod twisted joint of piston in swing handle and the hydraulic cylinder.Move back and forth by the hydraulic control piston, the driven rotary body is along the rotation of the protruding track on the base, and by roller, jaw, dental lamina seat, dental lamina radially, axially, circumferentially tighten oil pipe or unclamp.
The present invention has following advantage than prior art:
1, adopt hydraulic control, mechanized operation, the time and labour saving is improved work efficiency, and can be reduced personal injury.
2, in tripping operation, can be earlier with the hydraulic cylinder pressure release, this moment, oil pipe can not fall, and upwards carries oil pipe with crane then owing to the auto-lock function of this device, and this moment, dental lamina unclamped oil pipe automatically, can descend to bore.Thereby propose oil pipe and the simultaneously operating of unclamping dental lamina on having guaranteed, not only save trouble but also laborsaving.
Therefore 3, when being full of pressure fluid in the hydraulic cylinder, jaw is located by the jaw seat, and from axially, radially, circumferential three directions tighten oil pipe, thereby can bear reaction torque, make the present invention have the function of slips and back-up tong concurrently, have saved the operation of beating back-up tong.
4, base of the present invention is fixed on the wellhead flange dish, can prevents blowout effectively.
5, the self-locking mechanism of the present invention's design and the mechanism of hydraulic-driven rotary body can guarantee that slip system of the present invention has minimum height, and 30 tons of well workover slips, its design height only are 0.25～0.26m.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the structure sectional view of one embodiment of the present of invention.
Fig. 2 is the top plan view of the foregoing description.
The present invention further does following narration in conjunction with the accompanying drawings:
See figures.1.and.2.A kind of hydraulic slip system with three-direction slip comprises base (4), loam cake (10), side cover (11), its centre is provided with equally distributed three dental laminas (1), and dental lamina (1) is fixed on the dental lamina seat (2), and the medial surface of dental lamina seat (2) by dovetail groove and jaw (3) movingly.The medial surface of jaw (3) is the inclined-plane, and gradient is 1: 3.The outer middle side part of jaw (3) is fluted, and by bearing pin (9) installing roller (8), roller (8) outer rim contacts with the inwall of rotary body (6) in the groove.The front and back sidewall of jaw (3) is limited by jaw seat (16), and jaw seat (16) is connected as a single entity with base (4), thereby makes apparatus of the present invention can bear reaction torque, and has the function of back-up tong concurrently.The radial position of jaw (3) is rotated the inwall of body (6) and the contact point of roller (8) limits.Between the outer rim of jaw (3) and side cover (11) and base (4), respectively establish an extension spring (5), can guarantee that roller (8) remains with rotary body (6) inwall to contact.Rotary body (6) is an annular disc, its bottom is provided with groove, the protruding track (7) that is provided with base (4) movingly, thereby can along the circumferential direction rotate, the rotation of rotary body (6) is realized by hydraulic control by following driving mechanism, be fixed with swing handle (15) on rotary body (6) outer wall, swing handle (15) links with the piston rod (12) of the middle piston (13) of hydraulic cylinder (14), and hydraulic cylinder (14) can adopt the vibrating type fluid cylinder.Piston (13) when mobile, promptly promotes piston rod (12) under hydraulic control, rotate along track (7) by swing handle (15) driven rotary body (6).The inwall curved surface of rotary body (6) can guarantee to cut the footpath than being predetermined constant for waiting lift angle helical curved surface.In the time will tightening oil pipe, piston (13) moves to the diagram lower right under hydraulic control, by piston rod (12), swing handle (15), rotary body (6) is rotated counterclockwise, promotion roller (8), jaw (3), dental lamina seat (2) tooth, dental lamina (1) move radially and reach shown position, are about to the oil pipe chucking.In the time of need unclamping oil pipe, hydraulic pressure promotes piston (13) pulling rotary body (6) in the other direction and clockwise rotates, and extension spring (5) is with jaw (3), and dental lamina seat (2), dental lamina (1) tension are done radially outward to move, and oil pipe is promptly released.
