Description

Technical Field

[0001] This utility model relates to the field of auxiliary support technology, specifically to an auxiliary support for the maintenance of a track ball valve with positioning markings. Background Technology

[0002] Orbital ball valves, as a critical fluid control device, are widely used in pipeline systems under various harsh conditions, such as those in the petroleum, chemical, and natural gas industries. Their core working principle involves the valve stem driving a ball to rotate and axially displace within the valve seat, achieving opening, closing, and sealing functions. However, this unique "orbital" motion makes maintenance, especially when replacing the valve core (ball), grinding or inspecting the sealing surfaces, extremely difficult. Maintenance personnel must precisely rotate the ball to a specific angle and lift it to a specific height to successfully remove it from the valve cavity or detach it from the valve seat.

[0003] Traditional operations rely entirely on manual tools and experience from maintenance personnel, which is not only time-consuming and labor-intensive but also has many technical drawbacks: First, the adjustment of the ball angle lacks effective positioning indicators, relying entirely on visual observation and feel, making it prone to deviations. Even a slight angular error can cause interference or scratching between the ball and the valve seat, or even damage to the precision sealing surface, resulting in secondary damage. Second, centering and clamping the valve stem is difficult, and slippage is easy when applying torque, posing a safety hazard. Third, the lifting height of the valve stem is difficult to control precisely, making it impossible to ensure that the ball moves smoothly along the predetermined track. Currently, there is a lack of a dedicated maintenance tool on the market that integrates valve stem clamping, precise angle rotation and indication, and height control, resulting in low maintenance efficiency, inconsistent quality, and high safety risks.

[0004] Therefore, it is necessary to invent an auxiliary support for the maintenance of a track ball valve with positioning marks to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a maintenance auxiliary bracket for a track ball valve with positioning marks. By cooperating with the maintenance bracket and the angle adjustment mechanism, the reading function is enhanced, so as to solve the problem that the existing technology lacks a special maintenance tool that can integrate valve stem clamping, precise angle rotation and indication, and height control, resulting in low maintenance efficiency, inconsistent quality and high safety risks.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a maintenance auxiliary bracket for a track ball valve with positioning markings, comprising a maintenance frame, an angle adjustment mechanism disposed below the maintenance frame, a micro motor disposed below the maintenance frame, a worm gear fixedly connected to the output end of the micro motor, a worm wheel fitted to the outer side of the worm gear, the worm wheel being rotatably connected to the surface of the maintenance frame, an marking groove being formed on the surface of the maintenance frame, the top of the worm wheel being located inside the marking groove, an angle marking being fixedly connected to the surface of the marking groove, and an angle pointer being disposed above the worm wheel, the angle being displayed through the cooperation of the angle marking and the angle pointer.

[0007] Preferably, a dust baffle is fixedly connected to the top of the maintenance frame, and the micro motor is fixedly connected to the bottom of the maintenance frame. The dust baffle prevents damage to the micro motor and provides auxiliary support.

[0008] Preferably, a connecting column is fixedly connected to the top of the worm gear and an angle pointer is fixedly connected to the outer wall of the connecting column. An electric telescopic platform is fixedly connected inside the connecting column, and the electric telescopic platform is activated to drive the subsequent parts to rise and fall.

[0009] Preferably, the outer wall of the electric telescopic platform is marked with a height indicator, and the top of the electric telescopic platform is fixedly connected to a mounting base for installing subsequent parts.

[0010] Preferably, the surface of the mounting base is provided with a movable groove, and a clamping motor is fixedly connected to the left end of the mounting base, and a threaded rod is fixedly connected to the output end of the clamping motor. Starting the clamping motor drives the threaded rod to rotate.

[0011] Preferably, the threaded rod is rotatably connected to the inside of the mounting base and the thread directions at the left and right ends of the threaded rod are opposite. Two sets of linkage rods are slidably connected inside the movable groove and the linkage rods are threaded to the surface of the threaded rod, so that the threaded rod drives the linkage rods to move.

[0012] Preferably, a clamping pad is fixedly connected to the inner side of the linkage rod. The clamping pad is made of silicone rubber and is used to prevent damage to the valve body.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows: The combination of the inspection frame and the angle adjustment mechanism, along with the angle pointer and the angle mark, provides intuitive and precise visual positioning, ensuring the accuracy of the ball's posture adjustment. This fundamentally avoids damage to the sealing surface or improper installation caused by angle deviation. The application of micro motors and clamping motors enables remote mechanical operation, which not only significantly reduces the labor intensity of operators but also isolates personnel from the valve operating parts, significantly improving the inherent safety level of maintenance operations under high pressure or high-risk conditions. Furthermore, detailed designs such as dust baffles and silicone clamping pads further enhance the reliability of the equipment and the protection of the valve stem. Attached Figure Description

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model provides, for example Figure 1-4The illustrated auxiliary support for maintaining a track ball valve with positioning markings includes a maintenance frame 1. An angle adjustment mechanism 2 is located below the maintenance frame 1. The maintenance frame 1 includes a micro motor 201 positioned below it. A worm gear 202 is fixedly connected to the output end of the micro motor 201. A worm wheel 203 is fitted to the outer side of the worm gear 202 and rotatably connected to the surface of the maintenance frame 1. A marking groove 206 is formed on the surface of the maintenance frame 1, with the top of the worm wheel 203 located inside the marking groove 206. An angle marking is fixedly connected to the surface of the marking groove 206. 204. An angle pointer 205 is provided above the worm gear 203. The angle is displayed by the cooperation of the angle indicator 204 and the angle pointer 205. A dust baffle 11 is fixedly connected to the top of the maintenance frame 1. A micro motor 201 is fixedly connected to the bottom of the maintenance frame 1. The dust baffle 11 prevents damage to the micro motor 201 and provides auxiliary support. A connecting column 3 is fixedly connected to the top of the worm gear 203, and the angle pointer 205 is fixedly connected to the outer wall of the connecting column 3. An electric telescopic platform 4 is fixedly connected inside the connecting column 3. Activating the electric telescopic platform 4 drives the subsequent parts to rise and fall.

[0019] Refer to the instruction manual appendix Figure 1-4 The outer wall of the electric telescopic platform 4 is marked with a height indicator 5. A mounting base 6 is fixedly connected to the top of the electric telescopic platform 4, through which subsequent parts are installed. A movable groove 7 is formed on the surface of the mounting base 6. A clamping motor 10 is fixedly connected to the left end of the mounting base 6, and a threaded rod 12 is fixedly connected to the output end of the clamping motor 10. Starting the clamping motor 10 drives the threaded rod 12 to rotate. The threaded rod 12 is rotatably connected to the inside of the mounting base 6, and the threads at the left and right ends of the threaded rod 12 are in opposite directions. Two sets of linkage rods 8 are slidably connected inside the movable groove 7, and the linkage rods 8 are threaded to the surface of the threaded rod 12. The threaded rod 12 drives the linkage rods 8 to move. A clamping pad 9 is fixedly connected to the inner side of the linkage rod 8. The clamping pad 9 is made of silicone rubber. The device is constructed to prevent damage to the valve body through the clamping pad 9. The cooperation between the inspection frame 1 and the angle adjustment mechanism 2, as well as the cooperation between the angle pointer 205 and the angle mark 204, provides intuitive and accurate visual positioning, ensuring the accuracy of the ball's posture adjustment. This fundamentally avoids damage to the sealing surface or improper installation caused by angle deviation. The application of the micro motor 201 and the clamping motor 10 enables remote mechanical operation, which not only significantly reduces the labor intensity of operators but also isolates personnel from the valve operating parts, significantly improving the inherent safety level of maintenance operations under high pressure or high-risk conditions. Furthermore, the reliability of the equipment and the protection of the valve stem are further enhanced through detailed designs such as the dust baffle 11 and the silicone clamping pad 9.

[0020] The working principle of this practical application is as follows: Refer to the instruction manual appendix Figure 1-4During operation, the inspection frame 1 is first placed stably near the valve, and the clamping motor 10 is started. It drives the threaded rod 12 with opposite thread directions at both ends to rotate, forcing the two linkage rods 8 to slide synchronously towards or away from each other in the movable groove 7, thereby driving the clamping pad 9 to accurately clamp or release the valve stem, achieving automatic centering and fixing. Subsequently, the electric telescopic platform 4 is raised and lowered. By observing the height indicator 5 on its outer side, the lifting height of the valve stem can be precisely controlled to meet the specific stroke required for the ball to detach from the valve seat. The most critical angle adjustment is performed by the angle adjustment mechanism 2: after the micro motor 201 starts, it drives the worm gear 202 to rotate, which in turn drives the meshing worm wheel 203 to rotate. Since the worm wheel 203 is rigidly connected to the clamping mechanism of the electric telescopic platform 4 and above through the connecting column 3, its rotation is precisely transmitted to the clamped valve stem, causing the valve stem and the internal ball to rotate together. By observing the displacement change of the angle pointer 205 fixed on the worm wheel 203 relative to the angle indicator 204 fixed on the indicator groove 206, the operator can read the precise angle of the ball's rotation in real time and intuitively, thereby achieving precise positioning of the ball's working posture or maintenance position and completing the entire maintenance auxiliary process.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
