Description

Technical Field

[0001] This utility model relates to the technical field of valve installation auxiliary equipment, and in particular to an auxiliary alignment structure for valve installation. Background Technology

[0002] Valves are key components in pipeline systems that control fluid transport. During installation, it is essential to ensure that the mounting holes of the valve flange and the pipeline flange are precisely aligned in order to successfully tighten the bolts and ensure the sealing and stability of the pipeline system. Currently, valve alignment during installation often relies on the cooperation of multiple workers. The valve is first moved to the vicinity of the installation location, and then multiple workers manually lift and move the valve to align it.

[0003] However, the existing method of manually lifting and moving valves for alignment has obvious drawbacks: First, the valves themselves have a certain weight, making it difficult to maintain stability for a long time when manually lifted, and they are prone to shaking and shifting. This not only leads to poor alignment accuracy of the valve flange and the pipe flange mounting holes, but may also cause collision and scratches on the flange sealing surface, affecting the sealing performance of the subsequent pipeline system. Second, the alignment process lacks effective auxiliary positioning methods, relying entirely on manual visual judgment of the mounting hole alignment status, which has large visual errors. It requires repeated adjustments to the valve position to complete the alignment, making the operation process cumbersome and significantly reducing installation efficiency. Third, manual valve lifting for alignment is labor-intensive and prone to operational errors due to fatigue, posing safety hazards and failing to meet the actual needs for stable and safe valve installation.

[0004] To address this, an auxiliary alignment structure for valve installation is proposed. Utility Model Content

This not only leads to poor alignment accuracy of the valve flange and the pipe flange mounting holes, but may also cause collision and scratches on the flange sealing surface, affecting the sealing performance of the subsequent pipeline system. Second, the alignment process lacks effective auxiliary positioning means, and relies entirely on manual visual judgment of the mounting hole alignment status. The visual error is large, and the valve position needs to be repeatedly adjusted to complete the alignment. The operation process is cumbersome and significantly reduces the installation efficiency. Third, manual lifting of valves for alignment for a long time is labor-intensive and prone to operational errors due to fatigue, posing safety hazards and failing to meet the actual needs of stable and safe valve installation.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] An auxiliary alignment structure for valve installation includes a valve body 1, and an auxiliary alignment component 2 is provided on the top of the valve body 1.

[0027] The auxiliary alignment component 2 includes a top plate 201, which is located on top of the valve body 1. Support legs 202 are welded to the four corners of the bottom of the top plate 201. A translation and lifting structure 203 is provided on the rear side of the bottom of the top plate 201. A hanging frame 204 is fixedly connected to the bottom of the translation and lifting structure 203. A slide groove 205 is opened on the front side of the hanging frame 204. A two-way screw rod 206 is rotatably connected inside the slide groove 205. A rotating handle 207 is fixedly connected to the right side of the two-way screw rod 206. Arc-shaped clamping plates 208 are threadedly connected to both sides of the surface of the two-way screw rod 206. The arc-shaped clamping plates 208 are located on both sides of the valve body 1. The rear side of the arc-shaped clamping plates 208 is slidably connected to the inside of the slide groove 205. A deformation fitting pad 209 is fixedly connected to the inner side of the arc-shaped clamping plates 208.

[0028] In this embodiment: By setting the valve body 1 and the auxiliary alignment component 2, the auxiliary alignment component 2 is first placed above the valve body 1. The support legs 202 welded at the four corners of the bottom of the top plate 201 are firmly supported on the ground, and the front sides of the two rear support legs 202 are aligned with the rear side of the connecting pipe to further strengthen the stability of the device and provide a solid foundation for subsequent alignment operations, avoiding device shaking that could interfere with alignment accuracy. During operation, the rotating handle 207 on the front side of the lifting frame 204 is first rotated, which drives the bidirectional screw 206 inside the slide groove 205 to rotate. As the threads on both sides of the bidirectional lead screw 206 are opposite in direction, the arc-shaped clamp 208 connected to it will move towards the center along the slide groove 205 until the deformation-fitting pad 209 on the inner side of the arc-shaped clamp 208 tightly fits both sides of the valve body 1. The deformation-fitting pad 209 can slightly deform according to the surface shape of the valve body 1, enhancing the fit with the valve body 1 and firmly clamping the valve body 1. This replaces manual lifting and fundamentally avoids the problem of the valve body 1 easily shaking and shifting when manually lifted, while also protecting the valve. The flange sealing surface of the valve body 1 is protected against collisions and scratches. Then, the position is adjusted via the translational lifting structure 203 at the bottom rear of the top plate 201. The translational lifting structure 203 can move the bottom-fixed hanging frame 204, which in turn moves the valve body 1, achieving horizontal translation and vertical lifting of the valve body 1. Operators can precisely adjust the height and horizontal position of the valve body 1 according to the position of the pipe flange, eliminating the need for repeated manual movement of the valve body 1 and reducing alignment issues caused by visual errors. This allows for quick alignment of the valve body 1 flange with the pipe flange mounting holes. Throughout the process, the arc-shaped clamping plate 208 firmly holds the valve body 1, and the translational lifting structure 203 precisely adjusts the position, ensuring the alignment accuracy of the mounting holes, simplifying the operation process, improving installation efficiency, and completely eliminating the need for long-term manual lifting, reducing labor intensity, avoiding operational errors caused by fatigue, eliminating safety hazards, and meeting the actual requirements for stable and safe installation of the valve body 1.

[0029] Specifically, such as Figure 4 As shown, the translation and lifting structure 203 includes a sliding groove 2031, which is opened on the rear side of the top of the top plate 201. An adjusting screw 2032 is rotatably connected inside the sliding groove 2031.

[0030] Specifically, such as Figure 4 As shown, the adjusting screw 2032 is threadedly connected to a sliding block 2033 on its outer side, and the sliding block 2033 is slidably connected inside the sliding groove 2031.

[0031] Specifically, such as Figure 4 As shown, a lifting screw 2034 is rotatably connected inside the moving block 2033. A turntable 2035 is welded to the top of the lifting screw 2034. An internal threaded sleeve 2036 is welded to the center of the top of the hanging frame 204. A liner 2037 is welded to both sides of the top of the hanging frame 204. The top of the liner 2037 penetrates the bottom of the moving block 2033.

[0032] In this embodiment: By setting a translational lifting structure 203, the sliding groove 2031 is opened on the rear side of the top of the top plate 201, providing installation and movement space for the adjusting screw 2032 and the sliding block 2033. When it is necessary to adjust the horizontal position of the valve body 1, the adjusting screw 2032 is rotated. Since the adjusting screw 2032 is threadedly connected to the sliding block 2033, the sliding block 2033 will slide smoothly along the sliding groove 2031, driving the lower hanging frame 204 and the valve body 1 to move horizontally synchronously, achieving precise horizontal alignment. When it is necessary to adjust the height of the valve body 1, the turntable 2035 on the top of the lifting screw 2034 is rotated, and the lifting screw... The threaded engagement between the internal threaded sleeve 2036 on the top of the lifting frame 204 and the lifting frame 204 will cause the lifting frame 204 to move up and down. The bushings 2037 on both sides of the lifting frame 204 pass through the bottom of the shift block 2033, which can prevent the lifting frame 204 from shifting during lifting and ensuring the stability of height adjustment. Through the cooperation of the shift groove 2031, adjusting screw 2032, shift block 2033, lifting screw 2034, turntable 2035, internal threaded sleeve 2036 and bushing 2037, the horizontal position and height of the valve body 1 can be flexibly and accurately adjusted, allowing the valve flange to be quickly aligned with the pipe flange, replacing manual movement and adjustment, and improving alignment efficiency and accuracy.

[0033] Specifically, such as Figure 2 , Figure 5 As shown, a groove 3 is provided on the front side of the top of the top plate 201, and a lifting handle 4 is rotatably connected inside the groove 3.

[0034] Specifically, such as Figure 3 As shown, the inner side of the deformation bonding pad 209 is provided with anti-slip grooves 5, which are arranged in a cross pattern.

[0035] In this embodiment: by setting a groove 3, a lifting handle 4, and an anti-slip groove 5, the groove 3 is opened on the front side of the top of the top plate 201, and the lifting handle 4 is rotatably connected inside the groove 3. Normally, the lifting handle 4 can be stored in the groove 3 without occupying extra space. When it is necessary to move the entire auxiliary alignment component 2, the lifting handle 4 can be turned out of the groove 3, making it convenient for operators to hold and carry, and improving the ease of movement of the device. The anti-slip grooves 5 on the inner side of the deformation fitting pad 209 are distributed in a cross pattern, which can increase the friction between the deformation fitting pad 209 and the surface of the valve body 1. When the arc-shaped clamping plate 208 clamps the valve body 1, it further enhances the anti-slip effect, avoids the valve body 1 from sliding and shifting during the alignment process, ensures the stability of the clamping, and can also better protect the surface of the valve body 1 without affecting subsequent use.

[0036] Specifically, such as Figure 4 As shown, a handwheel 6 is welded to the left side of the adjusting screw 2032, and anti-slip textures are provided on the outer side of the handwheel 6.

[0037] Specifically, such as Figure 5 As shown, a sealing plate 7 is bolted to the rear side of the right side of the top plate 201. The sealing plate 7 is located on the right side of the sliding groove 2031, and the inner side of the sealing plate 7 is in contact with the right side of the adjusting screw 2032.

[0038] In this embodiment: by setting a hand-operated rotary disc 6 and a sealing plate 7, the hand-operated rotary disc 6 is welded to the left side of the adjusting screw 2032. The anti-slip texture on its outer side can increase the friction between the hand and the hand-operated rotary disc 6. When the operator rotates the adjusting screw 2032, it is easier to hold the hand-operated rotary disc 6 and it is less likely to slip, thus improving the convenience of operation. The sealing plate 7 is bolted to the rear side of the right side of the top plate 201 and is located on the right side of the shifting groove 2031. Its inner side contacts the right side of the adjusting screw 2032, which can limit and protect the right side of the adjusting screw 2032, prevent the adjusting screw 2032 from axially shifting during rotation, and ensure the stability of the cooperation between the adjusting screw 2032 and the shifting block 2033.

[0039] Working principle: During the alignment and installation of the auxiliary valve body 1, the auxiliary alignment component 2 is first moved above the valve body 1 by the lifting handle 4 in the groove 3 on the front side of the top plate 201. The lifting handle 4 is then released to retract it back into the groove 3, saving space. The support legs 202 welded to the four corners of the bottom of the top plate 201 are then placed firmly on the ground, with the front sides of the two rear support legs 202 aligned with the rear sides of the connecting pipes to further reinforce the stability of the device and prevent shaking during alignment. Next, the rotating handle 207 on the front side of the lifting frame 204 is rotated, causing the double-acting screw 206 inside the slide groove 205 to rotate. Because the threads on both sides of the double-acting screw 206 are in opposite directions, the threads connect... The arc-shaped clamp 208 attached thereto will move towards the center along the slide groove 205 until the deformation-fitting pad 209 on the inner side of the arc-shaped clamp 208 is tightly fitted to both sides of the valve body 1. The deformation-fitting pad 209 has cross-shaped anti-slip grooves 5 on the inner side, which can increase the friction with the surface of the valve body 1. At the same time, the deformation-fitting pad 209 can slightly deform according to the shape of the surface of the valve body 1 to enhance the fit and firmly clamp the valve body 1, replacing manual lifting. Then, the position of the valve body 1 is adjusted according to the position of the pipe flange. When horizontal adjustment is required, the handwheel 6 welded to the left side of the adjusting screw 2032 is held. The anti-slip texture on the outer side of the handwheel increases the friction and makes it easier to hold. The mechanism is designed to prevent slippage. Rotating the handwheel 6 causes the adjusting screw 2032 to rotate within the sliding groove 2031. The sliding block 2033, threadedly connected to the adjusting screw 2032, slides smoothly along the sliding groove 2031, thereby causing the lower hanging frame 204 and valve body 1 to move horizontally synchronously. When height adjustment is required, rotating the turntable 2035 at the top of the lifting screw 2034, which is rotatably connected inside the sliding block 2033, engages with the internal threaded sleeve 2036 welded to the center of the top of the hanging frame 204, causing the hanging frame 204 to move up and down. The bushings 2037 on both sides of the top of the hanging frame 204 penetrate the bottom of the sliding block 2033 to prevent the hanging frame 204 from shifting during lifting and lowering. To ensure stable height adjustment, the sealing plate 7 bolted to the rear right side of the top plate 201 contacts the right side of the adjusting screw 2032 during the entire adjustment process, limiting the adjustment screw 2032 and preventing axial displacement during rotation. This ensures the stability of the engagement between the adjusting screw 2032 and the moving block 2033. Through precise adjustment of the horizontal and vertical dimensions, the flange of the valve body 1 is quickly aligned with the mounting hole of the pipe flange without the need for repeated manual movement and lifting. This avoids alignment deviations caused by the swaying and offset of the valve body 1, protects the flange sealing surface from collision and scratches, reduces manual labor intensity, eliminates safety hazards, and ultimately efficiently completes the installation and alignment operation of the valve body 1.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
