Description

Technical Field

[0001] This utility model relates to the field of hydraulic clamp suspension technology, and in particular to a rotatable hydraulic clamp suspension device. Background Technology

[0002] In oilfield downhole operations, hydraulic tongs are commonly used for attaching and detaching tubing and drill pipe. Traditionally, a steel wire rope is used to suspend the hydraulic tongs at the wellhead, with the tong tail rope fixed to the derrick's leg. Adjusting the height of the suspended hydraulic tongs using this method is neither safe nor convenient.

[0003] For example, on May 2, 2001, a patent with publication number CN2428562Y, entitled "A Height Adjustment Device for Oilfield Well Workover Clamps," was disclosed. It consists of a small winch with a worm gear mechanism, a coupling, a wire rope, a fixed pulley, and hydraulic clamps. The small winch is driven by the worm gear mechanism; rotating the worm handle causes the wire rope on the small winch to flexibly adjust the height of the suspended hydraulic clamps. Due to the self-locking function of the worm gear mechanism, the adjusted height of the hydraulic clamps remains unchanged. This invention provides a convenient and flexible way to adjust the suspension height of the hydraulic clamps. However, when the hydraulic clamps leave or return to the wellhead, manual pulling of the wellhead tubing clamps is required, increasing labor intensity. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to propose a rotatable hydraulic clamp suspension device to solve the problem of increased labor intensity.

[0005] To achieve the above objectives, this utility model provides a rotatable hydraulic clamp suspension device, including a rotating lifting component. The rotating lifting component includes a connecting frame, and a rotating component for controlling the rotation of the connecting frame is connected to the lower end of the connecting frame. A horizontally arranged crossbeam is provided at the upper end of the connecting frame, and rollers are provided at both ends of the crossbeam. A hand-cranked winch is provided on the connecting frame, and a steel wire rope is wound on the hand-cranked winch. The steel wire rope passes through the two rollers to suspend the hydraulic clamp, and the steel wire rope is connected to the main clamp of the hydraulic clamp.

[0006] Optionally, the rotating component includes a motor and a reducer, with the output end of the motor connected to the input end of the reducer, and the output end of the reducer being fastened to the lower end of the connecting frame.

[0007] Optionally, a mobile platform is provided under the rotating lifting component.

[0008] Optionally, the connecting frame includes a lower support and an upper support, which are hinged together.

[0009] Optionally, a reinforcing rib is provided between the lower end face of the crossbeam and the side wall of the upper support.

[0010] Optionally, the mobile platform is provided with a vertically arranged support frame located on one side of the rotating lifting component, and the support frame is provided with a placement groove for supporting the upper support.

[0011] Optionally, a slide rail is provided on the side wall of the upper support, and the hand-cranked winch is slidably connected to the upper support through the slide rail. The hand-cranked winch is connected to the side wall of the upper support through a spring cylinder.

[0012] Optionally, the back clamp of the hydraulic clamp is slidably connected to the upper support via a safety rod.

[0013] Optionally, the safety bar, crossbeam, and upper support are all telescopic components that can be extended and adjusted.

[0014] The beneficial effects of this utility model are as follows: This utility model provides a rotatable hydraulic clamp suspension device. When using this device, the steel wire rope on the hand-cranked winch is connected to the main clamp of the hydraulic clamp. The overall height of the hydraulic clamp is adjusted by loosening or tightening the steel wire rope through the hand-cranked winch, so that the hydraulic clamp can adapt to the height of the wellhead tubing coupling. The rotation component can drive the connecting frame to swing at a certain angle, so that the hydraulic clamp leaves or returns to the wellhead. This reduces the labor intensity of wellhead workers pulling tubing clamps, improves work efficiency, and reduces the labor intensity of workers. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0020] like Figures 1 to 5 As shown, a rotatable hydraulic clamp suspension device includes a rotating lifting component. The rotating lifting component includes a connecting frame. The lower end of the connecting frame is connected to a rotating component for controlling the rotation of the connecting frame. A horizontally arranged crossbeam 6 is provided at the upper end of the connecting frame. Rollers 13 are provided at both ends of the crossbeam 6. A hand-cranked winch 11 is provided on the connecting frame. A steel wire rope 12 is wound on the hand-cranked winch 11. The steel wire rope 12 passes through the two rollers 13 to suspend the hydraulic clamp 9. The steel wire rope 12 is connected to the main clamp of the hydraulic clamp 9. That is, after the steel wire rope 12 passes around the outer peripheral grooves of the two rollers 13 in sequence, its free end is connected to the main clamp lifting ring of the hydraulic clamp 9 through a hook / shackle, forming a two-point suspension.

[0021] When using this device, the wire rope 12 on the hand-cranked winch 11 is connected to the main clamp of the hydraulic clamp 9. The overall height of the hydraulic clamp 9 is adjusted by loosening or tightening the wire rope 12 through the hand-cranked winch 11, so that the hydraulic clamp 9 can adapt to the height of the wellhead tubing coupling. The start of the rotating part can drive the connecting frame to swing at a certain angle, so that the hydraulic clamp 9 leaves or returns to the wellhead, reducing the labor intensity of wellhead workers pulling tubing clamps, improving work efficiency, and reducing the labor intensity of workers.

[0022] Among them, roller 13 is a coaxial double-groove pulley.

[0023] The rotating component includes a motor 7 and a reducer 8. The output end of the motor 7 is connected to the input end of the reducer 8. The output end of the reducer 8 is fastened to the lower end of the connecting frame with bolts and nuts. The motor 7 drives the connecting frame to rotate through the reducer 8, which controls the rotation of the hydraulic clamp 9 suspended on the connecting frame. The connecting frame rotates and swings at a certain angle, causing the hydraulic clamp 9 to leave or return to the wellhead, greatly reducing the labor intensity of the wellhead workers pulling the tubing clamp. The motor 7 is hydraulically driven, but can also be electrically or pneumatically driven; a gear and rack swing cylinder can also be used to replace the above combination of motor 7 and reducer 8.

[0024] A movable platform 1 is provided under the rotating lifting component. The rotating parts on the rotating lifting component are fastened to the movable platform 1 by bolts and nuts. The movable platform 1 is provided with movable wheels for movement, which facilitates the movement of the rotating lifting component.

[0025] The connecting frame includes a lower support 5 and an upper support 4, which are hinged together by a hinge. The angle between the upper support 4 and the lower support 5 can be changed by the hinge, thereby reducing the overall height of the connecting frame and facilitating subsequent transportation. A locking member is provided between the lower support 5 and the upper support 4 on one side of the hinge. The locking member includes a locking tongue and a locking buckle that cooperates with the locking tongue to lock. The locking tongue and the locking buckle are respectively provided on the lower support 5 and the upper support 4. The locking member is used to fasten the lower support 5 and the upper support 4.

[0026] A reinforcing rib is connected between the lower end face of the crossbeam 6 and the side wall of the upper support 4 on the connecting frame, which facilitates the improvement of the connection strength between the crossbeam 6 and the upper support 4.

[0027] The mobile platform 1 is provided with a vertically arranged support frame 2 located on one side of the rotating lifting component. The support frame 2 is provided with a placement groove 3 for supporting the upper support 4. The upper support 4 is swung and placed on the placement groove 3 on the support frame 2, which makes it easy to fold the connecting frame. During transportation, the upper support 4 can be laid down and embedded in the placement groove 3. The whole is transported together with the mobile platform 1, which is convenient for transportation.

[0028] A slide rail 15 is provided on the side wall of the upper support 4. The hand-cranked winch 11 is slidably connected to the upper support 4 via the slide rail 15. The lower part of the hand-cranked winch 11 is connected to the side wall of the upper support 4 via a spring cylinder 14. When using this device, the wire rope 12 on the hand-cranked winch 11 is connected to the main clamp of the hydraulic clamp 9. The overall height of the hydraulic clamp 9 is adjusted by loosening or tightening the wire rope 12 through the hand-cranked winch 11, so that the hydraulic clamp 9 adapts to the height of the wellhead pipe string coupling. Then the hydraulic clamp 9 can work. When the hydraulic clamp 9 is working, the back clamp of the hydraulic clamp 9 bites the coupling. The back clamp of the hydraulic clamp 9 maintains a constant height. When the hydraulic clamp 9 is engaged, the height of the main clamp of the hydraulic clamp 9 will decrease as the thread is turned. When the hydraulic clamp 9 is disengaged, the height of the main clamp will increase as the thread is turned out. This requires that while suspending the hydraulic clamp 9, it can also rise or fall a certain distance when the hydraulic clamp 9 is working. For this purpose, the hand-cranked winch 11 is slidably connected to the upper support 4. The hand-cranked winch 11 can slide up and down. At the same time, the hand-cranked winch 11 is connected to the upper support 4 through the spring cylinder 14. In this way, the spring cylinder 14 can ensure that the hydraulic clamp 9 can continue to rise or fall within a certain range.

[0029] Furthermore, placing the spring cylinder 14 below the hand-cranked winch 11 significantly reduces the overall height of the device compared to placing the spring cylinder 14 above the main clamp of the hydraulic clamp 9 or above the hand-cranked winch 11.

[0030] The back clamp of the hydraulic clamp 9 is slidably connected to the upper support 4 via the safety rod 10. The safety rod 10, the crossbeam 6, and the upper support 4 are all telescopic adjustable components. The telescopic components can include a sleeve-type telescopic sleeve, which is locked by a positioning pin to facilitate adjustment of the height of the hydraulic clamp 9 and the distance between the hydraulic clamp 9 and the upper support 4. The adjustment can be made according to the installation distance at the wellhead so that the center of the hydraulic clamp 9 is aligned with the center of the wellhead.
