Description

Technical Field

[0001] This utility model relates to the technical field of water-proof conduit processing equipment, and in particular to a clamping mechanism for welding water-proof conduits. Background Technology

[0002] Water-proof conduits can effectively control the movement speed of groundwater and oil reservoir water, reduce the time and amount of water entering the oil reservoir, and prevent the mixing of oil, gas and water, thereby ensuring the efficiency of oil reservoir extraction. Commonly used materials are steel pipes or plastic pipes, which have good corrosion resistance and long service life. Welding is often required during the processing of water-proof conduits.

[0003] Currently, when welding water-proof conduits, the ends of two sets of water-proof conduits need to be connected to each other. Due to the lack of a limiting clamping mechanism for the conduit body, accidental displacement can easily occur during the welding process, causing misalignment of the ends of the two sets of water-proof conduits. This reduces the welding quality and affects the normal use of the water-proof conduit. Therefore, this utility model proposes a clamping mechanism for welding water-proof conduits that is different from the existing technology to solve the above-mentioned technical problems. Utility Model Content

[0004] In order to improve the problem mentioned above that accidental displacement can easily occur during the welding process, resulting in misalignment of the ends of the two sets of water-proof conduits, this utility model provides a clamping mechanism for welding water-proof conduits.

[0005] This utility model provides a clamping mechanism for welding water-proof conduits, which adopts the following technical solution:

[0006] A clamping mechanism for welding a water-tight conduit includes a connecting inner plate, with connecting outer frames movably fitted at both ends of the connecting inner plate. Sleeves are installed at both ends of two sets of connecting outer frames. Sleeve plates are slidably fitted into the inner cavities of multiple sets of sleeves. Threaded advancement components are installed at the upper ends of the inner surfaces of the multiple sets of sleeve plates. Clamping plates are installed at the ends of the multiple sets of threaded advancement components. Anti-slip pads are affixed to the outer walls of the multiple sets of clamping plates on their adjacent sides.

[0007] By adopting the above technical solution, the two sets of water-proof conduits to be welded are placed on the two sets of clamping mechanisms for welding the water-proof conduits. Then, the threaded advancement assembly is turned to drive the clamping plate to move horizontally until the outer wall of the anti-slip pad is in close contact with the outer wall of the water-proof conduit, thereby facilitating the clamping of water-proof conduits of different specifications and making them less likely to be accidentally displaced during the welding process.

[0008] Optionally, the threaded advancement assembly includes a threaded tube, which is fixedly embedded in the sleeve plate. A threaded crossbar is threaded through the inner cavity of the threaded tube. One end of the threaded crossbar is rotatably connected to the outer wall of the clamping plate through a bearing, and a turntable is installed on the other end of the threaded crossbar.

[0009] Optionally, a base plate is fixed at the top center of multiple sets of connecting outer frames.

[0010] By adopting the above technical solution, the rotating disc drives the threaded crossbar to rotate synchronously. Under the action of the threaded tube, the threaded crossbar moves horizontally during rotation, thereby pushing the clamping plate to move synchronously on the top wall of the connecting outer frame until the outer wall of the anti-slip pad is in close contact with the outer wall of the water-proof conduit.

[0011] Optionally, multiple sets of positioning holes are evenly opened on both sides of the bottom wall of the connecting inner plate, and elastic components are installed on the bottom walls of the multiple sets of connecting outer frames, and positioning blocks that engage and match with the positioning holes are installed on the top walls of the multiple sets of elastic components.

[0012] Optionally, the elastic component includes a spring, and multiple sets of the spring are provided. The multiple sets of springs are fixed to the bottom wall of the connecting outer frame. The bottom end of the multiple sets of springs is fixed with a positioning frame that penetrates through the bottom wall of the outer frame. The top end of the multiple sets of positioning frames is connected and fixed to the positioning block. The bottom end of each of the multiple sets of positioning frames is equipped with a pull ring.

[0013] By adopting the above technical solution, by holding the pull ring and applying downward force, the positioning frame and positioning block can be moved down synchronously and separated from the positioning hole. Then, the connecting outer frame is moved horizontally to the appropriate position. Then, the pull ring is released, and the positioning frame and positioning block are automatically pulled back to their original positions under the elastic force of the spring, so that the positioning block can re-engage with the positioning hole at the corresponding position, thereby facilitating the clamping of water-proof pipes of different lengths.

[0014] Optionally, multiple sets of support legs are installed on the bottom walls of the multiple sets of connecting outer frames, and wheels are installed on the bottom walls of the multiple sets of support legs.

[0015] By adopting the above technical solution, the position of the clamping mechanism for welding the water-proof conduit can be adjusted by pushing the connecting outer frame to drive the support leg to move synchronously through the wheel body.

[0016] Optionally, the outer wall of the sleeve is evenly provided with multiple sets of screw holes, and the top of the outer wall of the sleeve is provided with a screw that matches the thread of the screw hole.

[0017] By adopting the above technical solution, the screw is turned to separate it from the screw hole at the top. Then, the threaded crossbar is lifted upward to drive the sleeve plate to move upward synchronously to the appropriate position in the inner cavity of the sleeve. The screw is turned in the opposite direction to re-thread it to the screw hole at the corresponding position, which facilitates the clamping of large-diameter water-proof conduit.

[0018] In summary, this utility model has at least one of the following beneficial effects:

[0019] Place the two sets of water-proof conduits to be welded on the top of the pads on the two sets of water-proof conduit welding clamping mechanisms, and then turn the turntable to drive the threaded crossbar to rotate synchronously, thereby pushing the clamping plate to move synchronously until the outer wall of the anti-slip pad is in close contact with the outer wall of the water-proof conduit, so as to facilitate clamping water-proof conduits of different specifications and prevent them from being accidentally displaced during the welding process.

[0024] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.

[0025] Please refer to the attached diagram in the instruction manual. Figure 1 and 2 An embodiment of this utility model provides a clamping mechanism for welding a water-proof conduit, including a connecting inner plate 6. The lateral cross-section of the connecting inner plate 6 is set in an I-shape. Both ends of the connecting inner plate 6 are movably fitted with connecting outer frames 7. Both ends of the two sets of connecting outer frames 7 are equipped with sleeves 2. The top end of the sleeves 2 is set in an open shape. The inner cavities of multiple sets of sleeves 2 are slidably fitted with sleeve plates 9 that penetrate the top opening of the sleeves 2. The upper end of the inner cavity of multiple sets of sleeve plates 9 is equipped with a threaded advancement component, which includes a threaded tube 14.

[0026] Please refer to the attached diagram in the instruction manual. Figure 1 and 2The threaded tube 14 is fixedly embedded in the upper end of the sleeve plate 9, and the threaded tube 14 is positioned above the sleeve 2. The threaded tube 14 has a threaded crossbar 11 threaded through it. One end of the threaded crossbar 11 is rotatably connected to the clamping plate 13 via a bearing. The longitudinal section of the clamping plate 13 is L-shaped. The bottom wall of the clamping plate 13 is in contact with the top wall of the connecting outer frame 7. A turntable 10 is installed on the other end of the threaded crossbar 11. Anti-slip pads 12 are pasted on the outer walls of multiple clamping plates 13 that are close to each other. A pad 5 is fixed at the top middle position of multiple connecting outer frames 7. The top wall of the pad 5 is arc-shaped, and the opening of the arc structure faces upward.

[0027] Place the two sets of water-proof conduits to be welded on the top of the pad 5 on the clamping mechanism for welding the two sets of water-proof conduits respectively. Then, turn the turntable 10 to drive the threaded crossbar 11 to rotate, thereby pushing the clamping plate 13 to move synchronously until the outer wall of the anti-slip pad 12 is in close contact with the outer wall of the water-proof conduit. Then, simply move the position of the clamping mechanism for welding the water-proof conduit so that the ends of the two sets of water-proof conduits are connected to each other, thereby facilitating the clamping of water-proof conduits of different specifications and making it less likely to be accidentally displaced during the welding process.

[0028] Please refer to the attached diagram in the instruction manual. Figure 1 , 2 3. Multiple sets of positioning holes 15 are evenly opened on both sides of the bottom wall of the inner plate 6. Multiple sets of elastic components are installed on the bottom wall of the outer frame 7. The elastic components include springs 17. Multiple sets of springs 17 are provided and fixed on the bottom wall of the outer frame 7. The bottom end of the multiple sets of springs 17 is fixed with a positioning frame 18 that penetrates the bottom wall of the outer frame 7. The top of the multiple sets of positioning frames 18 is equipped with a positioning block 16 that engages with the positioning hole 15. The bottom end of the multiple sets of positioning frames 18 is equipped with a pull ring 19.

[0029] By grasping the pull ring 19 and applying downward force, the positioning frame 18 and the positioning block 16 can be moved down synchronously until the positioning block 16 separates from the positioning hole 15 at the corresponding position. Then, the connecting outer frame 7 is moved horizontally so that it slides on the outer wall of the connecting inner plate 6 to the appropriate position. Then, the pull ring 19 is released, and the positioning frame 18 and the positioning block 16 are automatically pulled back to their original positions under the elastic force of the spring 17, so that the positioning block 16 can re-engage with the positioning hole 15 at the corresponding position. This allows the size of the overlapping of the connecting inner plate 6 and the connecting outer frame 7 to be adjusted, which facilitates the clamping of water-proof conduits of different lengths.

[0030] Please refer to the attached diagram in the instruction manual. Figure 1 Multiple sets of supporting legs 3 are installed on the bottom walls of the multiple sets of connecting outer frames 7, and each set of supporting legs 3 is equipped with a wheel 4 on its bottom wall. The wheel 4 is a universal wheel. Pushing the connecting outer frame 7 moves the supporting legs 3 synchronously through the wheel 4, thereby adjusting the position of the clamping mechanism for welding the water-tight conduit.

[0031] Please refer to the attached diagram in the instruction manual. Figure 1 Multiple sets of screw holes 8 are evenly provided on the lower end of the outer wall of the sleeve plate 9. A screw 1 that matches the thread of the screw hole 8 is passed through the top of the outer wall of the sleeve 2. Tighten the screw 1 to separate it from the screw hole 8. Then lift the threaded cross bar 11 upward to move the sleeve plate 9 upward to the appropriate position. Tighten the screw 1 in the opposite direction to reconnect it with the screw hole 8 at the corresponding position. This allows the height of the clamping plate 13 to be adjusted, making it convenient to clamp the large-diameter water-proof conduit.

[0032] Working principle: When using the clamping mechanism for welding water-proof conduits, first place the two sets of water-proof conduits to be welded on the top of the pads 5 on the two sets of clamping mechanisms. Then, turn the turntable 10 to drive the threaded crossbar 11 to rotate synchronously. Under the action of the threaded tube 14, the threaded crossbar 11 moves horizontally during rotation, thereby pushing the clamping plate 13 to move synchronously on the top wall of the connecting frame 7 until the outer wall of the anti-slip pad 12 is in close contact with the outer wall of the water-proof conduit. Then, simply move the position of the clamping mechanism to make the ends of the two sets of water-proof conduits align with each other, so as to clamp water-proof conduits of different specifications and prevent them from accidentally shifting during the welding process.

[0033] When the clamping mechanism for welding the water-tight conduit is moved, simply push the connecting outer frame 7 to drive the support leg 3 to move synchronously through the wheel body 4. When the diameter of the water-tight conduit to be clamped is large, simply turn the screw 1 to separate it from the screw hole 8 at the top. Then, lift the threaded cross bar 11 upward to drive the sleeve plate 9 to move synchronously upward in the inner cavity of the sleeve 2 to the appropriate position. Turn the screw 1 in the opposite direction to re-thread it to the screw hole 8 at the corresponding position. This allows the height of the clamping plate 13 to be adjusted, making it convenient to clamp large-diameter water-tight conduits.

[0034] By gripping the pull ring 19 and applying downward force, the positioning frame 18 and the positioning block 16 can be moved downward synchronously, causing the spring 17 to stretch and deform elastically until the positioning block 16 separates from the positioning hole 15 at the corresponding position. Then, the connecting outer frame 7 is moved horizontally so that it slides on the outer wall of the connecting inner plate 6 to the appropriate position. Then, the pull ring 19 is released, and the positioning frame 18 and the positioning block 16 are automatically pulled back to their original positions under the elastic force of the spring 17, so that the positioning block 16 can re-engage with the positioning hole 15 at the corresponding position. This allows adjustment of the overlapping dimensions of the connecting inner plate 6 and the connecting outer frame 7, thus facilitating the clamping of water-proof conduits of different lengths.
