Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically to an auxiliary device for a socket welding lifting check valve. Background Technology

[0002] The auxiliary devices of a socket weld lift check valve are a set of additional structures that work together with the valve body to ensure its sealing performance, functional stability and ease of maintenance. These devices typically include a socket weld connection end, a valve disc guide mechanism, a pressure self-tightening sealing system, as well as safety function modules such as flow direction indicators and limit mechanisms. In high temperature and high pressure scenarios, the auxiliary devices may integrate designs such as a bonnetless self-tightening structure and metal spiral wound gaskets to cope with thermal stress or corrosive environments.

[0003] A socket welding pipe fitting assembly auxiliary device disclosed in Chinese Utility Model Patent Application Publication CN216829441U, while allowing for easier gripping of the fittings by controlling the assembly gap through rotating the adjusting screw, and measuring the assembly gap by having a circular arc-shaped clamping gripper, and a scale on the free end of the adjusting screw, presents several drawbacks. Existing equipment can only rotate the welded parts, which generates high temperatures during welding that can damage the rotating motor. Furthermore, it is difficult to insulate the rotating motor, support the equipment, and prevent tipping, leading to equipment damage. Adjustments are also difficult to make according to the height required by the check valve and the welded parts, and accidental touches and damage to the controller are unavoidable, potentially causing equipment malfunctions. Therefore, this utility model is proposed to address these issues. Utility Model Content

[0015] In summary, the technical effects and advantages of this utility model are as follows:

[0016] 1. This utility model has a reasonable structure. By inserting a fixing plate into the check valve, the fixing plate is moved on the electric push rod, which fixes the check valve. The rotating motor makes the rotating seat rotate on the bearing seat, and the push rod seat rotates on the rotating seat, which makes the fixing plate drive the check valve to rotate.

[0017] 2. In this utility model, by pressing the right fixing button, the right fixing component moves the right bearing rod within the right telescopic rod. Adjusting the height of the right clamping component and the right telescopic rod allows the right fixing button to pop out from the corresponding right fixing hole, thus fixing the right telescopic rod. The right clamping motor causes the right clamping rod to rotate on the right clamping seat, allowing the right rotating column to rotate and the welded part to rotate. Pressing the left fixing button moves the left fixing component within the left telescopic rod. Adjusting the height of the left clamping component and the left telescopic rod allows the left fixing button to pop out from the corresponding left fixing hole, thus fixing the left telescopic rod. The left clamping motor causes the left clamping rod to rotate on the left clamping seat, allowing the left rotating column to rotate and the welded part to rotate. This allows the right and left clamping components to fix the welded part. Adjusting the height of the welded part allows the worker to weld the check valve and the welded part.

[0018] 3. In this utility model, the support plate rotates on the support base until it forms a certain angle with the ground. By tightening the support bolts, the support plate is fixed on the support base. This allows the support assembly to support the equipment, making the equipment more stable and reducing shaking and tipping, which could lead to equipment damage. The control cover rotates on the control panel to protect the controller. The controller can control the equipment, and this protection also reduces accidental touches and damage to the controller, which could lead to reduced work efficiency. Attached Figure Description

The right rotating column 112 can rotate on the right clamping seat 111, and the right rotating column 116 can rotate on the right clamping rod 115, allowing the welded part to rotate within the clamping assembly. By pressing the left fixing button 124, the left fixing component 12 is inserted into the left telescopic rod 13, allowing the left bearing rod 8 to move within the left telescopic rod 13. The operator adjusts the left... Adjusting the clamping assembly 14 to a suitable height allows the left telescopic rod 13 to be adjusted, causing the left fixing button 124 to pop out from the corresponding left fixing hole, thus fixing the left telescopic rod 13. The left clamping motor 144 drives the left clamping rod 145 to rotate, causing it to rotate on the left clamping seat 141. The left rotating column 142 can rotate on the left clamping seat 141, and the left rotating column 146 can rotate on the left clamping rod 145, allowing the welded part to rotate within the clamping assembly. This allows the right clamping assembly 11 and the left clamping assembly 14 to fix the welded part, and allows the right telescopic rod 10 and the left telescopic rod 13 to extend and retract, adjusting the welded part to a suitable height according to the position of the check valve. This facilitates welding of the check valve and the welded part, saving the worker's physical effort.

[0036] like Figure 4 and Figure 5 As shown, in this embodiment, support components 5 are inserted into both sides of the support base 1. Each support component 5 includes a support base 501, a support bolt 502, a support plate 503, and a support pad 504. A support bolt 502 is threaded through one side of the support base 501. The support plate 503 is rotatably connected inside the support base 501. A support pad 504 is inserted into the upper surface of the support plate 503. A control plate 6 is inserted into one side of the support base 1. A control cover 601 is rotatably connected to one side of the control plate 6. A controller 602 is provided on the upper surface of the control plate 6. During use, the support plate 503 supports the support base... Rotate the support plate 503 on the support 501 to form a 45-degree angle with the ground. Tighten the support bolts 502 to fix the support plate 503 on the support base 501. This allows the support assembly 5 to support the equipment, making the equipment more stable and reducing the likelihood of shaking or tipping, which could lead to equipment damage. Rotating the control cover 601 on the control plate 6 can protect the controller 602. The controller 602 can be used to control the equipment, and its protection can reduce accidental activation and damage, which could lead to reduced work efficiency.

[0037] The working principle of this practical application is as follows:

[0038] During use, the operator moves the equipment to the desired position and rotates the support plate 503 on the support base 501 until it forms a 45-degree angle with the ground. Tightening the support bolts 502 secures the support plate 503 to the support base 501, thus supporting the equipment with the support assembly 5, making the equipment more stable and reducing shaking and tipping that could cause damage. Rotating the control cover 601 on the control plate 6 protects the controller 602, which controls the equipment. Protecting the controller 602 reduces the risk of damage. Accidental contact and damage to device 602 lead to reduced work efficiency. By inserting the fixing plate 17 into the check valve and extending / retracting the electric push rod 16, the fixing plate 17 can move on the electric push rod 16, thereby fixing the check valve. The rotary motor 2 rotates on the support seat 1, causing the rotating seat 4 to rotate on the support seat 1, which in turn causes the push rod seat 15 to rotate on the rotating seat 4. This allows the fixing plate 17 to drive the check valve to rotate, facilitating more comprehensive welding of the check valve during welding work and improving the welding quality of the check valve. The rotating plate 3 can isolate the check valve during welding. The heat generated during welding is reduced, thus minimizing damage to the rotary motor 2 caused by the high temperatures, reducing the reduction in work efficiency due to damage to the rotary motor 2, and extending the service life of the rotary motor 2. The right clamping motor 114 drives the right clamping rod 115 to rotate, causing the right clamping rod 115 to rotate on the right clamping seat 111. The right rotating column 112 can rotate on the right clamping seat 111, and the right rotating column 116 can rotate on the right clamping rod 115, allowing the welded part to rotate within the right clamping assembly 11. The left clamping motor 144 drives the left clamping rod 145 to rotate, causing the left clamping rod 145 to rotate on the left... The clamping seat 141 rotates, and the left rotating column 142 allows rotation on the left clamping seat 141. The left rotating column 146 allows rotation on the left clamping rod 145, allowing the welded part to rotate within the left clamping assembly 14. By pressing the right fixing button 904, the right fixing assembly 9 is inserted into the right telescopic rod 10, causing the right bearing rod 7 to move within the right telescopic rod 10. The operator adjusts the right clamping assembly 11 to a suitable height, adjusting the right telescopic rod 10 so that the right fixing button 904 pops out from the corresponding right fixing hole, fixing the right telescopic rod 10. By pressing the left fixing button 124...Insert the left fixing component 12 into the left telescopic rod 13, allowing the left bearing rod 8 to move within the left telescopic rod 13. The operator adjusts the left clamping component 14 to a suitable height, adjusting the left telescopic rod 13 so that the left fixing button 124 pops out from the corresponding left fixing hole, fixing the left telescopic rod 13. This allows the right clamping component 11 and the left clamping component 14 to fix the welded part, and allows the right telescopic rod 10 and the left telescopic rod 13 to extend and retract, adjusting the welded part to a suitable height according to the position of the check valve. This facilitates welding the check valve and the welded part, saving the operator's physical effort.
