Description

Technical Field

[0001] This utility model belongs to the field of oil well workover technology, specifically relating to a well workover rig tilt angle fine adjustment device. Background Technology

[0002] In oil well workover operations, the precise adjustment of the derrick tilt angle directly affects the safety and efficiency of the operation. Currently, most derrick tilt angle adjustment devices commonly available on the market are unable to achieve independent and rapid adjustment of the lateral and longitudinal angles. Some devices use a single-dimensional adjustment structure, which cannot flexibly adjust the derrick's lateral and longitudinal tilt angles simultaneously when facing complex terrain or special workover requirements. This makes it difficult to quickly adjust the derrick to the appropriate angle, prolonging the operation preparation time. Different specifications and types of workover rigs have different requirements for derrick tilt angle adjustment devices, but most existing devices have poor versatility and are difficult to adapt to various workover rig derricks, limiting their application range. Utility Model Content

[0003] This utility model provides a fine-tuning device for the tilt angle of a workover rig, which solves the problem that existing rig tilt angles are inconvenient to adjust flexibly in both the lateral and longitudinal tilt angles.

[0004] This utility model provides the following technical solution: A tray is included, with an outer hinge plate hinged to the inner wall of the tray, and an inner hinge plate hinged to the inner wall of the outer hinge plate. An outer mounting bracket and an inner mounting bracket are respectively installed at the bottom ends of the tray and the outer hinge plate. An outer hydraulic jack corresponding to one end of the outer hinge plate is installed on the inner wall of the outer mounting bracket. An outer fixing plate is installed at one end of the outer hinge plate. An outer support block is hinged to the inner wall of the outer fixing plate, and an outer support plate is installed at the bottom end of the outer support block. One end of the outer hydraulic jack corresponds to the outer support plate. An inner hydraulic jack corresponding to the inner hinge plate is installed on the inner wall of the inner mounting bracket. An inner fixing plate is installed at the bottom end of the inner hinge plate. An inner support block is hinged to the inner wall of the inner fixing plate, and an inner support plate is installed at one end of the inner support block. The inner hydraulic jack corresponds to the inner support plate.

[0005] The mounting plate and the outer hinge plate are each equipped with a mounting block, and the outer hinge plate and the inner hinge plate are each equipped with a rotating rod at both ends. The mounting block is slidably connected to the rotating rod.

[0006] The outer mounting bracket is offset from the inner mounting bracket, and the outer hinge plate and the inner hinge plate are perpendicularly corresponding.

[0007] The pallet is equipped with a positioning frame, and the positioning frame is threadedly connected with an inner positioning rod and an outer positioning rod.

[0008] The positioning frame corresponds to the outer hinge plate and the inner hinge plate, the outer positioning rod corresponds to both ends of the outer hinge plate, and the inner positioning rod corresponds to both ends of the inner hinge plate.

[0009] The inner support plate and the outer support plate are respectively provided with an inner slide rail and an outer slide rail at their bottoms, and one end of the inner hydraulic jack and the outer hydraulic jack matches the inner wall of the inner slide rail and the inner wall of the inner slide rail, respectively.

[0010] The beneficial effects of this utility model are as follows: the outer hinge plate is supported by the support plate, and the outer hinge plate supports the inner hinge plate. The angle adjustment of the outer and inner hinge plates is relatively perpendicular. With the hinge structure design of the outer and inner hinge plates, and with the height adjustment of the outer and inner hinge plates by the supporting components such as the outer hydraulic jack and the inner hydraulic jack, the tilt angle of the derrick can be quickly adjusted in the horizontal and vertical directions. Moreover, the derrick can be accurately adjusted to the required angle according to different well workover operation needs, meeting diverse operation scenarios and improving the accuracy and adaptability of the operation.

[0011] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0017] Please see Figures 1-4The present invention provides the following technical solution: a support plate 1, an outer hinge plate 2 hinged to the inner wall of the support plate 1, an inner hinge plate 3 hinged to the inner wall of the outer hinge plate 2, an outer mounting bracket 21 and an inner mounting bracket 31 respectively installed at the bottom ends of the support plate 1 and the outer hinge plate 2, an outer hydraulic jack 22 corresponding to one end of the outer hinge plate 2 installed on the inner wall of the outer mounting bracket 21, an outer fixing plate 23 installed at one end of the outer hinge plate 2, an outer support block 24 hinged to the inner wall of the outer fixing plate 23, an outer support plate 25 installed at the bottom end of the outer support block 24, one end of the outer hydraulic jack 22 corresponding to the outer support plate 25, an inner hydraulic jack 32 corresponding to the inner hinge plate 3 installed on the inner wall of the inner mounting bracket 31, an inner fixing plate 33 installed at the bottom end of the inner hinge plate 3, an inner support block 34 hinged to the inner wall of the inner fixing plate 33, an inner support plate 35 installed at one end of the inner support block 34, and the inner hydraulic jack 32 corresponding to the inner support plate 35.

[0018] In this implementation scheme: the support plate 1 serves as the carrier of the supporting device, and is hinged to the inner wall of the support plate 1 by the outer hinge plate 2. While the outer hinge plate 2 is supported and erected by the support plate 1, its angle within the inner wall of the support plate 1 can be adjusted. Simultaneously, the inner hinge plate 3, hinged to the inner wall of the outer hinge plate 2, can be rotated to adjust its angle within the outer hinge plate 2. When supporting the derrick installed on the inner hinge plate 3, it can be supported and fixed to the bottom end of the support plate 1 by the outer mounting bracket 21. The outer hydraulic jacks 22 installed on the inner wall of the outer mounting bracket 21 correspond to both ends of the outer hinge plate 2. By adjusting the support height of the left and right sets of outer hydraulic jacks 22 at the bottom of the outer hinge plate 2, the angle of the outer hinge plate 2 can be adjusted. At this time, the outer fixing plate 23 installed at the bottom end of the outer hinge plate 2 is hinged to the outer support block 24. The outer support plate 25 installed at the bottom end of the outer support block 24 corresponds to one end of the outer hydraulic jack 22, and the outer support plate 25 has… The external hydraulic jacks 22 have a certain length, ensuring that they can support the external support plate 25. When the four external hydraulic jacks 22 are positioned in pairs at both ends of the external hinge plate 2 for support, the extension and retraction of the external hydraulic jacks 22 can adjust the angle of the external hinge plate 2, allowing the lateral tilt of the internal hinge plate 3 to be adjusted. Similarly, the internal hydraulic jacks 32 installed on the inner wall of the inner mounting bracket 31 correspond to the internal fixed plate 33. The internal support blocks 34 hinged to the inner wall of the internal fixed plate 33 install the internal support plate 35, allowing the internal hydraulic jacks 32 to adjust the support height of the internal support plates 35 installed at both ends of the internal hinge plate 3. This allows the longitudinal height of the internal hinge plate 3 within the external hinge plate 2 to be adjusted, enabling the longitudinal and lateral adjustment of the derrick tilt angle installed on the internal hinge plate 3. This allows the derrick to be adjusted to the required tilt angle according to actual needs, enabling the device to effectively adjust the position of the derrick and facilitating well repair operations.

[0019] Mounting blocks 11 are installed on both the support plate 1 and the outer hinge plate 2. Rotating rods 12 are installed at both ends of the outer hinge plate 2 and the inner hinge plate 3. The mounting blocks 11 and the rotating rods 12 are slidably connected. The mounting blocks 11 installed on the support plate 1 and the outer hinge plate 2 are both circular in shape with the rotating rods 12, so that the rotating rods 12 can rotate on the inner wall of the mounting blocks 11, so that the inner hinge plate 3 can be hinged to the inner wall of the outer hinge plate 2 and supported by the outer hinge plate 2. At the same time, the outer hinge plate 2 is hinged to the inner wall of the support plate 1, so that the outer hinge plate 2 is supported on the inner wall of the support plate 1.

[0020] The outer mounting bracket 21 is offset from the inner mounting bracket 31, and the outer hinge plate 2 and the inner hinge plate 3 are perpendicularly corresponding. The offset between the outer mounting bracket 21 and the inner mounting bracket 31 can prevent the outer mounting bracket 21 and the inner mounting bracket 31 from being limited, and can allow the outer hydraulic jack 22 and the inner hydraulic jack 32 to correspond to the two ends of the outer hinge plate 2 and the inner hinge plate 3 respectively, so that the outer hinge plate 2 and the inner hinge plate 3 can be adjusted at an angle.

[0021] A positioning frame 4 is installed on the support plate 1. The positioning frame 4 is threaded with an inner positioning rod 41 and an outer positioning rod 42. The positioning frame 4 can install the inner positioning rod 41 and the outer positioning rod 42 so that after the angle of the outer hinge plate 2 and the inner hinge plate 3 is adjusted, the four outermost outer positioning rods 42 can correspond to the two ends of the outer hinge plate 2. One end of the outer positioning rod 42 is adjusted to be supported at the top of the outer hinge plate 2, and the bottom end of the inner positioning rod 41 can be supported on the top of the inner hinge plate 3. After the angle of the outer hinge plate 2 and the inner hinge plate 3 is adjusted, the tilt angle of the derrick can be adjusted, thus stabilizing the derrick.

[0022] The positioning frame 4 corresponds to the outer hinge plate 2 and the inner hinge plate 3. The outer positioning rod 42 corresponds to both ends of the outer hinge plate 2, and the inner positioning rod 41 corresponds to both ends of the inner hinge plate 3. The positioning frame 4 corresponds to the outer hinge plate 2 and the inner hinge plate 3, so that the inner positioning rod 41 and the outer positioning rod 42 can respectively support and limit the outer hinge plate 2 and the inner hinge plate 3.

[0023] The inner support plate 35 and the outer support plate 25 are respectively provided with an inner slide rail 36 and an outer slide rail 26 at their bottoms. One end of the inner hydraulic jack 32 and the outer hydraulic jack 22 matches the inner slide rail 36 and the inner wall of the inner slide rail 36. The inner slide rail 36 is located at the bottom of the inner support plate 35. When the inner hydraulic jack 32 supports the bottom of the inner support plate 35, the outer hinge plate 2 and the inner hinge plate 3 change angles. After the positions of their two ends change, it can ensure that the outer hydraulic jack 22 and the inner hydraulic jack 32 are within the outer slide rail 26 and the inner slide rail 36, so that they maintain support for the two ends of the outer hinge plate 2 and the inner hinge plate 3.

[0024] The working principle and usage process of this utility model are as follows: The support plate 1 is fixedly installed at the designated position on the workover rig to ensure its stability and reliability. The outer hinge plate 2 is then hinged to the inner wall of the support plate 1, and the inner hinge plate 3 is hinged to the inner wall of the outer hinge plate 2. Simultaneously, the outer mounting bracket 21 and the inner mounting bracket 31 are respectively installed at the bottom ends of the support plate 1 and the outer hinge plate 2, with the outer hydraulic jack 22 corresponding to one end of the outer hinge plate 2 and the inner hydraulic jack 32 corresponding to the inner hinge plate 3. When it is necessary to adjust the derrick's lateral tilt angle, the support height of the outer support plate 25 is changed by controlling the extension and retraction of the left and right sets of outer hydraulic jacks 22, thereby adjusting the angle of the outer hinge plate 2. When adjusting the derrick's longitudinal tilt angle, the extension and retraction of the inner hydraulic jack 32 is operated to change the support height of the inner support plate 35. This allows for longitudinal angle adjustment of the inner hinge plate 3 within the outer hinge plate 2. During adjustment, the sliding connection between the mounting block 11 and the rotating rod 12 ensures smooth rotation of the outer hinge plate 2 and the inner hinge plate 3. After the derrick tilt angle is adjusted to the required angle, the inner positioning rod 41 and the outer positioning rod 42 are rotated so that the four outermost outer positioning rods 42 are supported on the top of the outer hinge plate 2, and the bottom end of the inner positioning rod 41 is supported on the top of the inner hinge plate 3, thus stabilizing and limiting the outer hinge plate 2 and the inner hinge plate 3 to prevent the derrick angle from changing during operation. After the well repair operation is completed, the inner positioning rod 41 and the outer positioning rod 42 are released, and the outer hydraulic jack 22 and the inner hydraulic jack 32 are retracted, restoring the outer hinge plate 2 and the inner hinge plate 3 to their initial state for easy use next time.
