Description

Technical Field

[0001] This utility model belongs to the field of hoisting valve technology, specifically relating to a hoisting structure for a hoisting valve. Background Technology

[0002] A lifting structure for a valve is a special load-bearing component and connection system designed on the valve body or auxiliary parts to meet the lifting requirements of a lifting valve. This structure ensures that the valve can be lifted safely and stably during transportation, installation and maintenance through preset mechanical support points and connection methods, avoiding damage to the valve body or internal components due to uneven stress.

[0003] However, the lifting structure of hoisting valves mostly adopts a design form that is fixedly connected to the valve body, such as welded lifting lugs and integrated lifting rods. Although it can meet the hoisting needs of a single specification valve, it has exposed significant limitations in actual engineering applications. Because this type of structure lacks adjustability, it is impossible to dynamically adjust the position or height of the lifting point according to the hoisting needs. As a result, when facing the hoisting of multiple specifications of valves, the risk of hoisting imbalance often occurs due to the mismatch between the lifting point and the valve's center of gravity and the uneven force on the slings, which greatly restricts the flexibility of hoisting operations.

[0004] To address the aforementioned issues, this application proposes a hoisting valve hoisting structure. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides a hoisting valve hoisting structure, which improves the flexibility of hoisting operations.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hoisting valve hoisting structure, including a valve, with two sliding groove frames arranged above the valve. Each sliding groove frame has a threaded sleeve rod rotatably connected to its inner wall. Each sliding groove frame has two sliding brackets slidably connected inside. The inner wall of each set of sliding brackets is threadedly connected to the outer surface of the threaded sleeve rod. Each sliding groove frame has limit rings on its front and back sides. Each set of limit rings has a turning bracket on its opposite side. Each threaded sleeve rod has two sliding rods slidably connected inside. The opposite ends of each set of sliding rods are fixedly connected to the opposite sides of each set of turning brackets. Each sliding bracket has a connecting bracket fixedly connected to its upper surface. Each connecting bracket has a sliding plate slidably connected to its inner wall. Each sliding plate has a lifting lug above it. Each connecting bracket has a limit rod engaged with its inner wall. The outer surface of each limit rod is in contact with the inner wall of the sliding plate.

[0007] As a preferred embodiment of this utility model, the outer surface of the valve is fixedly connected to two fixing brackets, and the upper surface of each fixing bracket is fixedly connected to the bottom surface of the sliding groove bracket.

[0008] As a preferred embodiment of this utility model, each of the sliding groove frames has two reinforcing plates fixedly connected to its bottom surface, and the bottom surface of each reinforcing plate is fixedly connected to the outer surface of the valve.

[0009] As a preferred embodiment of this utility model, each of the sliding groove frames has a support plate fixedly connected to its inner wall, and the inner wall of each support plate is rotatably connected to the outer surface of the threaded sleeve rod.

[0010] As a preferred technical solution of this utility model, each of the sliding groove frames is fixedly connected to a fixing ring on both the front and back sides, and the side of each set of fixing rings that is far apart from each other is fixedly connected to the side of each set of limiting rings that is close to each other.

[0011] As a preferred technical solution of this utility model, each set of rotating frames has a connecting ring fixedly connected to the side of each set of rotating frames that is far apart from each other, and each set of connecting rings has a handle fixedly connected to the side of each set that is far apart from each other.

[0012] As a preferred embodiment of this utility model, each of the sliding plates has a mounting bracket fixedly connected to its upper surface, and the inner wall of each mounting bracket is fixedly connected to the outer surface of the lug.

[0013] As a preferred technical solution of this utility model, each of the limiting rods has two positioning rings threadedly connected to its outer surface, and the side of each group of positioning rings that is close to each other is in contact with the two sides of the connecting frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The valve is stably hoisted by the addition of lifting lugs, and the height of the lifting lugs can be flexibly adjusted by the sliding plate's telescopic sliding within the connecting frame. Combined with the locking of the limiting rod, the adjusted height position is ensured to be stable and reliable. Simultaneously, the threaded sleeve rod has reverse threads on both sides. When the screwing frame is rotated in the same direction, the sliding rod and threaded sleeve rod can be rotated within the sliding groove frame. Utilizing the reverse characteristics of the threads, the two sliding frames can be driven to move away from or closer to each other within the sliding groove frame, thereby enabling lateral position adjustment of the connecting frame, sliding plate, and lifting lugs. Furthermore, the sliding engagement of the sliding rod within the threaded sleeve rod allows the screwing frame to be embedded within the limiting ring. The interlocking structure of the two effectively limits the threaded sleeve rod, precisely locking the adjusted lateral position. This achieves multi-dimensional flexible adjustment of the hoisting structure, significantly improving the adaptability of hoisting operations to valves of different specifications and complex working conditions.

[0024] Please see Figure 1-6The present invention provides the following technical solution: a hoisting valve hoisting structure, including a valve 1, two sliding groove frames 2 are provided above the valve 1, each sliding groove frame 2 has a threaded sleeve rod 7 rotatably connected to its inner wall, two sliding frames 6 are slidably connected inside each sliding groove frame 2, the inner wall of each set of sliding frames 6 is threadedly connected to the outer surface of the threaded sleeve rod 7, each sliding groove frame 2 has a limit ring 11 on its front and back, each set of limit rings 11 has a screwing frame 5 on its opposite side, each threaded sleeve rod 7 has two sliding rods 14 slidably connected inside, each set of sliding rods 14 has an opposite end fixedly connected to the opposite side of each set of screwing frames 5, each sliding frame 6 has a connecting frame 9 fixedly connected to its upper surface, each connecting frame 9 has a sliding plate 17 slidably connected to its inner wall, each sliding plate 17 has a lifting lug 15 above its upper surface, each connecting frame 9 has a limit rod 19 engaged in its inner wall, and the outer surface of each limit rod 19 is in contact with the inner wall of the sliding plate 17.

[0025] In this embodiment, the outer surface of the threaded sleeve 7 is provided with two sections of threads with opposite directions of rotation. When the threaded sleeve 7 is driven to rotate in the same direction by the screwing frame 5, based on the transmission characteristics of the left and right threads, the two sliding frames 6 can be driven to slide in opposite directions in the sliding groove frame 2, thereby quickly adjusting the lateral distance between the two lifting points and accurately adapting to the center of gravity distribution requirements of valves 1 of different specifications. At the same time, the corresponding positions of the sliding plate 17 and the connecting frame 9 are provided with equidistant limit holes. The limit rod 19 passes through the limit hole to realize the positioning and locking of the sliding plate 17 and the connecting frame 9. By selecting the limit holes at different positions, the multi-level height adjustment and precise positioning of the lifting lug 15 can be realized.

[0026] Specifically, two fixing brackets 3 are fixedly connected to the outer surface of the valve 1. The upper surface of each fixing bracket 3 is fixedly connected to the bottom surface of the sliding groove bracket 2. In this embodiment, the fixing brackets 3 can fix the sliding groove bracket 2 to the valve 1, thereby enabling the valve 1 and the sliding groove bracket 2 to be used in a fixed manner.

[0027] Specifically, each sliding groove frame 2 has two reinforcing plates 4 fixedly connected to its bottom surface. The bottom surface of each reinforcing plate 4 is fixedly connected to the outer surface of the valve 1. In this embodiment, the reinforcing plates 4 can support the sliding groove frame 2 onto the valve 1, thereby further enhancing the stability of the sliding groove frame 2.

[0028] Specifically, each sliding groove frame 2 has a support plate 8 fixedly connected to its inner wall, and the inner wall of each support plate 8 is rotatably connected to the outer surface of the threaded sleeve rod 7. In this embodiment, the support plate 8 can support the threaded sleeve rod 7 into the sliding groove frame 2, thereby improving the stability of the rotation of the threaded sleeve rod 7.

[0029] Specifically, each sliding groove frame 2 has a fixing ring 10 fixedly connected to its front and back sides. The side of each set of fixing rings 10 that is far apart from each other is fixedly connected to the side of each set of limiting rings 11 that is close to each other. In this embodiment, the fixing rings 10 can fix the limiting rings 11 to the sliding groove frame 2, so that the limiting rings 11 can be fixed and used.

[0030] Specifically, each set of rotating frames 5 has a connecting ring 12 fixedly connected to one side away from each other, and each set of connecting rings 12 has a handle 13 fixedly connected to one side away from each other. In this embodiment, the handle 13 is fixed to the rotating frame 5 through the connecting ring 12. Holding the handle 13 can drive the rotating frame 5 to move axially along the threaded sleeve 7 through the sliding rod 14, so as to achieve axial engagement or disengagement with the limiting ring 11, thereby locking or unlocking the rotation of the threaded sleeve 7.

[0031] Specifically, each sliding plate 17 has a mounting bracket 16 fixedly connected to its upper surface, and the inner wall of each mounting bracket 16 is fixedly connected to the outer surface of the lug 15. In this embodiment, the lug 15 can be fixed to the sliding plate 17 through the mounting bracket 16, thereby enabling the lug 15 to drive the sliding plate 17 to move.

[0032] Specifically, each limiting rod 19 has two positioning rings 18 threadedly connected to its outer surface. The side of each set of positioning rings 18 that is close to each other is in contact with the two sides of the connecting frame 9. In this embodiment, the positioning rings 18 are used to make them tightly abut against the two sides of the connecting frame 9, so that the limiting rod 19 can be locked in the preset position of the connecting frame 9, ensuring the stability of the height adjustment of the sliding plate 17.

[0033] The working principle and usage process of this utility model are as follows: First, the sliding groove frame 2 is securely installed above the valve 1 using the fixing frame 3 and the reinforcing plate 4, forming a basic support structure. Then, the lifting point position is adjusted according to the specifications of the valve 1 to be lifted. At this time, the handle 13 is pulled axially, causing the screwing frame 5 to disengage from the limiting ring 11. Simultaneously, the sliding rod 14 slides outward within the threaded sleeve 7, thereby unlocking the threaded sleeve 7. Then, the handle 13 is rotated to drive the screwing frame 5 to rotate the threaded sleeve 7. The reverse threads at both ends allow the two sliding frames 6 to slide synchronously towards or in opposite directions within the sliding groove frame 2. After adjusting the lateral spacing of the two lifting lugs 15 to match the center of gravity of the valve 1, the handle 13 is pushed to allow the screwing frame 5 and the sliding rod 14 to move outward. 4. Slide the threaded sleeve 7 inward and lock it with the limiting ring 11. At the same time, slide the sliding plate 17 up or down to adjust the lifting lug 15 to the appropriate height of the lifting equipment hook. After aligning the sliding plate 17 with the limiting hole of the connecting frame 9, insert the limiting rod 19 and tighten the positioning ring 18 to fix the height. Then, pass the sling through the lifting lug 15 to ensure that the sling is vertical and the center of gravity of valve 1 is on the same vertical line as the lifting point. Start the lifting equipment and lift slowly. After the operation is completed, loosen the positioning ring 18, pull out the limiting rod 19, reset the sliding plate 17, turn the handle 13 to return the sliding frame 6 to the initial spacing, and tighten the frame 5 and the sliding rod 14 to lock them with the limiting ring 11 in the threaded sleeve 7. Finally, check and clean all the connection parts.
