Technical Field

[0001] This utility model relates to the field of tilt angle adjustment technology, and in particular to a horizontal tilt angle adjustment device for an automated anti-tipping system for well workover rigs. Background Technology

[0002] Oil wells are holes drilled using drilling methods. During oil well workover, hydraulic rotating outriggers are used to support and fix the workover rig.

[0003] Chinese utility model patent CN221664668U discloses a hydraulic rotating outrigger. In use, this device uses two gears, a crank handle, a rod, a limit block, a spring, and a socket to limit the outrigger's position, improving its stability. However, in practice, the device requires manual pulling of the rod and observation of alignment with the socket, making operation cumbersome and delaying response time in emergency situations. Therefore, this invention addresses these issues by proposing a horizontal tilt angle adjustment device for an automated anti-tipping system for workover rigs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a horizontal tilt angle adjustment device for an automated anti-tipping system for well workover rigs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The horizontal tilt angle adjustment device of the automated anti-tipping system for well workover rigs includes a base. An adjustment groove is provided at the upper end of the base. A slide is movably connected in the adjustment groove. Two sets of side plates are fixedly connected to the end face of the base and are symmetrically arranged. A frame is rotatably connected between the two sets of side plates. A hydraulic cylinder is fixedly connected to the bottom of the frame. The telescopic section of the hydraulic cylinder extends through the top of the frame to the outside. A connecting plate is rotatably connected to the outer wall of the frame. The end of the connecting plate away from the frame is rotatably connected to the slide. A drive mechanism for driving the slide is installed in the adjustment groove.

[0006] Preferably, the driving mechanism includes a threaded rod rotatably connected to the inner wall of the adjusting groove, and the slide is threadedly connected to the threaded section of the threaded rod.

[0007] Preferably, two sets of limiting rods are fixedly connected to the inner wall of the adjusting groove, and the slide block is slidably connected to the outer wall of the two sets of limiting rods.

[0008] Preferably, a fixing plate is fixedly connected to the side wall of the slide block, a connecting rod is slidably connected to the outer wall of the fixing plate, a cleaning brush is fixedly connected to the end of the connecting rod, and the cleaning brush is slidably connected to the outer wall of the threaded rod.

[0009] Preferably, a limiting block is fixedly connected to the end of the connecting rod away from the cleaning brush. The radius of the limiting block is larger than the radius of the connecting rod. A spring is sleeved on the outer wall of the connecting rod. One end of the spring is fixedly connected to the limiting block, and the other end of the spring is fixedly connected to the end face of the fixing plate.

[0010] Preferably, a servo motor is fixedly connected to the side wall of the base, and the end of the output shaft of the servo motor is fixedly connected coaxially to the threaded rod.

[0011] This utility model has the following beneficial effects: 1. The linkage drive structure of the servo motor, threaded rod and slide of this utility model replaces the traditional operation method of manually pulling the insertion rod and observing the alignment of the insertion hole. When the tilt monitoring system sends an abnormal signal, the servo motor can respond immediately and drive the threaded rod to rotate, causing the slide to slide quickly along the limit rod. In conjunction with the hydraulic cylinder and connecting plate, the frame angle is automatically adjusted without manual intervention. This effectively solves the problems of cumbersome operation and delayed response time in emergency situations, and greatly improves the emergency adjustment efficiency of the system.

[0012] 2. In this utility model, during the movement of the slide, the elasticity of the spring keeps the cleaning brush in contact with the outer wall of the threaded rod, promptly removing dust, oil and other impurities from the surface of the threaded rod. This prevents the accumulation of impurities from affecting the thread transmission accuracy between the threaded rod and the slide, ensuring the reliability and accuracy of the horizontal tilt adjustment process. From a structural design perspective, this reduces problems such as adjustment jamming caused by improper maintenance. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-3 The horizontal tilt angle adjustment device of the automated anti-tipping system for well workover rig includes a base 1, an adjustment groove 2 at the upper end of the base 1, a slide 10 movably connected in the adjustment groove 2, two sets of side plates 6 fixedly connected to the end face of the base 1 and arranged symmetrically, a frame 7 rotatably connected between the two sets of side plates 6, a hydraulic cylinder 8 fixedly connected to the bottom of the frame 7, the telescopic section of the hydraulic cylinder 8 extending through the top of the frame 7 to the outside, a connecting plate 9 rotatably connected to the outer wall of the frame 7, the end of the connecting plate 9 away from the frame 7 being rotatably connected to the slide 10, and a drive mechanism for driving the slide 10 to move is installed in the adjustment groove 2. Furthermore, by driving the slide block 10 to move within the adjustment groove 2, and in conjunction with the linkage structure of the hydraulic cylinder 8 and the connecting plate 9, the angle of the frame 7 can be automatically adjusted. This eliminates the need for tedious manual observation and alignment of the insertion holes, effectively solving the problem of delayed response time due to manual operation in emergency situations, and improving the automation level of tilt adjustment and emergency response efficiency.

[0018] The drive mechanism includes a threaded rod 4 rotatably connected to the inner wall of the adjusting groove 2, and a slide block 10 threadedly connected to the threaded section of the threaded rod 4; Furthermore, the threaded transmission structure of the threaded rod 4 features high transmission accuracy and strong stability. Through the cooperation between the threaded section and the slide 10, the rotary motion can be converted into linear motion, providing a reliable drive for the precise movement of the slide 10.

[0019] Two sets of limiting rods 5 are fixedly connected to the inner wall of the adjusting groove 2. The slide block 10 is slidably connected to the outer wall of the two sets of limiting rods 5. A fixing plate 11 is fixedly connected to the side wall of the slide block 10. A connecting rod 13 is slidably connected to the outer wall of the fixing plate 11. A cleaning brush 12 is fixedly connected to the end of the connecting rod 13. The cleaning brush 12 is slidably connected to the outer wall of the threaded rod 4. Furthermore, the cleaning brush 12 moves synchronously with the slide block 10 to clean the outer wall of the threaded rod 4, which can remove dust, oil and other impurities attached to the threaded rod 4 in a timely manner, and avoid the accumulation of impurities affecting the thread transmission efficiency between the threaded rod 4 and the slide block 10.

[0020] One end of the connecting rod 13 away from the cleaning brush 12 is fixedly connected to a limiting block 14. The radius of the limiting block 14 is larger than the radius of the connecting rod 13. A spring 15 is sleeved on the outer wall of the connecting rod 13. One end of the spring 15 is fixedly connected to the limiting block 14, and the other end of the spring 15 is fixedly connected to the end face of the fixing plate 11. Furthermore, the elasticity of the spring 15 allows the cleaning brush 12 to always adhere to the outer wall of the threaded rod 4, and adaptively adjusts the cleaning pressure during the rotation of the threaded rod 4, ensuring that impurities on the surface of the threaded rod 4 can be effectively removed under different working conditions.

[0021] The servo motor 3 is fixedly connected to the side wall of the base 1, and the end of the output shaft of the servo motor 3 is fixedly connected to the threaded rod 4 coaxially. Furthermore, the servo motor 3 is connected to an external tilt monitoring system to synchronously control the rotation of the threaded rod 4.

[0022] In this utility model, when the device is in use: when the workover rig is in the work-ready state, the base 1 is stably placed on the ground, the slide 10 in the adjustment groove 2 is stopped in the initial position, the frame 7 maintains the initial posture through the rotational connection of the two side plates 6, the hydraulic cylinder 8 is in the incompletely extended state, and the cleaning brush 12 touches the outer wall of the threaded rod 4 under the action of the spring 15.

[0023] When the tilt monitoring system detects that the horizontal tilt angle of the workover rig exceeds the safety threshold, an external control command triggers the servo motor 3 to start. Its output shaft drives the threaded rod 4 to rotate at a constant speed. The engagement between the threaded section and the slide block 10 converts the rotational motion into linear motion, allowing the slide block 10 to slide smoothly along the trajectory defined by the two sets of limit rods 5. During the sliding process, the fixing plate 11 on the side wall of the slide block 10 drives the cleaning brush 12 to move synchronously through the connecting rod 13. The elastic thrust of the spring 15 ensures that the cleaning brush 12 always adheres to the surface of the threaded rod 4, promptly cleaning impurities in the thread gap and preventing foreign objects from affecting the transmission accuracy.

[0024] As the position of the slide block 10 changes, the connecting plate 9 pushes the frame 7 to rotate around the rotation axis of the side plate 6, simultaneously activating the extension and retraction of the hydraulic cylinder 8: when the slide block 10 moves away from the side plate 6, the hydraulic cylinder 8 extends synchronously to maintain the support rigidity of the frame 7; conversely, it retracts to accommodate angle adjustment. During this process, the limiting rod 5 effectively restricts the lateral displacement of the slide block 10, ensuring the precise linkage trajectory of the connecting plate 9 and avoiding adjustment lag caused by misalignment of the insertion rod in traditional manual operation.

[0025] In summary, this device requires no manual intervention during adjustment. The precise speed control of the servo motor 3, combined with the high-precision transmission of the threaded rod 4, ensures a linear relationship between the displacement of the slide block 10 and the tilt angle change of the frame 7. The system can automatically correct itself within a short time after receiving an abnormal tilt angle signal. The cooperation mechanism between the cleaning brush 12 and the spring 15 keeps the threaded rod 4 clean during continuous operation, ensuring the long-term stable operation of the drive mechanism. This fundamentally solves the problems of cumbersome manual operation and delayed response in emergency situations, improving the automation level and safety reliability of the well workover rig's anti-tipping system.

[0026] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
