Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, and in particular to an alignment fixture for connecting power pipes. Background Technology

[0002] With the development of modern society, the construction and equipment installation of power engineering projects are becoming increasingly complex, especially the connection and installation process of power pipelines. As an important component of power transmission and distribution, the accuracy of power pipeline connections directly affects the safety and operational efficiency of power facilities. To improve the accuracy and efficiency of power pipeline connections, connection clamps are widely used as auxiliary tools to ensure the stability and safety of power pipeline connections.

[0003] Traditional alignment clamps for power pipe connections typically place the pipes on a platform of uniform height. Once the pipes are aligned, the clamp's locking mechanism secures them in place, preparing them for welding or other connection work. However, in actual use, the clamp requires workers to constantly push and squeeze the two pipes to ensure alignment at the connection point. Even a slight collision can cause gaps between the pipes, increasing the difficulty of welding. Therefore, an alignment clamp for power pipe connections is proposed to solve the above problems. Utility Model Content

[0033] 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.

[0034] Reference Figures 1-5 This utility model provides an embodiment of an alignment clamp for connecting power pipes, comprising a base 1, a lower locking block 2 slidably connected to the top of the base 1, a stepper motor 3 fixedly connected to the middle of the lower locking block 2, a lead screw 8 fixedly connected to the output end of the stepper motor 3, a limit component installed in the middle of the lower locking block 2, a threaded block 19 threadedly connected to the outer circumference of the lead screw 8, an upper locking block 4 fixedly connected to the middle of the threaded block 19, a pipe 7 placed between the lower locking block 2 and the upper locking block 4, two connecting blocks 10 fixedly connected to the top of the base 1, a bidirectional threaded rod 20 rotatably connected to the middle of each of the two connecting blocks 10, a rocker arm 11 fixedly connected to one end of the bidirectional threaded rod 20, a locking component installed on the outer side of one of the connecting blocks 10, and the outer circumference of the bidirectional threaded rod 20 threadedly connected to... A threaded block 21 is connected to the base 1. A diagonal rod 12 is rotatably connected to the middle of the threaded block 21. A connecting seat 22 is rotatably connected to the other end of the diagonal rod 12. The connecting seat 22 is fixedly connected to the outside of the lower locking block 2. A reset assembly is installed on the top of the base 1. The reset assembly includes a fixing block 13. A sleeve 23 is fixedly connected to the middle of the fixing block 13. A round rod 24 is slidably connected to the middle of the sleeve 23. A stop block 29 is fixedly connected to one end of the round rod 24. The other end of the round rod 24 is fixedly connected to the middle of the lower locking block 2. A compression spring 28 is sleeved on the outer periphery of the round rod 24. The compression spring 28 is located in the middle of the sleeve 23. The limiting assembly includes a sliding rod 5. The sliding rod 5 is fixedly connected to the middle of the lower locking block 2. A slider 6 is fixedly connected to the outer periphery of the upper locking block 4. The slider 6 is slidably connected to the outer periphery of the sliding rod 5. First, the rocker arm 11 drives the bidirectional threaded rod 20 to rotate, causing the two threaded blocks 21 on the outer periphery of the bidirectional threaded rod 20 to move towards each other. This causes the inclined rod 12 to retract and push the two lower locking blocks 2 away from each other. At the same time, as the bidirectional threaded rod 20 moves, the round rod 24 drives the stop block 29 to squeeze the compression spring 28. Under the action of the locking assembly, the bidirectional threaded rod 20 is prevented from resetting. Then, the pipe 7 is placed between the lower locking block 2 and the upper locking block 4, and the connection of the pipe 7 is pushed past the lower locking block 2 and the upper locking block 4. The stepper motor 3 drives the threaded block 19 to move, so that the threaded block 19 drives the upper locking block 4 to fix the pipe 7. Then, the locking assembly is unlocked, so that the compression spring 28 can push the stop block 29. This causes the two lower locking blocks 2 to move closer to each other through the round rod 24, thereby causing the connection of the two pipes 7 to fit together, avoiding gaps, improving the convenience of welding, and reducing manpower consumption.

[0035] Reference Figure 3 and Figure 4 The engaging assembly includes a ratchet 27, which is fixedly connected to the outer periphery of the bidirectional threaded rod 20. A pawl 26 is rotatably connected to the outer side of one of the connecting blocks 10, and a spring plate 25 is installed on the outer side of the connecting block 10. The spring plate 25 contacts the pawl 26, and the pawl 26 contacts the ratchet 27. When the bidirectional threaded rod 20 rotates, it drives the ratchet 27 to rotate. Since the teeth of the ratchet 27 are aligned with the pawl 26, the ratchet 27 can move the pawl 26. At the same time, under the push of the spring plate 25, the pawl 26 can always be in contact with the ratchet 27, thereby preventing the bidirectional threaded rod 20 from reversing and resetting. After the pipe 7 is fixed, the pawl 26 is pressed to separate from the ratchet 27 so that the compression spring 28 can drive the two pipes 7 to engage through the round rod 24.

[0036] Reference Figure 1 and Figure 2 A limiting groove 17 is provided in the middle of the base 1, and a limiting block 18 is fixedly connected to the bottom of the lower locking block 2. The limiting block 18 is slidably connected in the middle of the limiting groove 17. When the lower locking block 2 moves, it will drive the limiting block 18 to slide in the middle of the limiting groove 17, thereby ensuring the stability of the lower locking block 2 during the sliding process.

[0037] Reference Figure 1 and Figure 6 The top of the base 1 is fixedly connected to a support block 9. The middle of the lower block 2, the upper block 4, and the support block 9 are all slidably connected to an insert block 30. The end of the insert block 30 near the pipe 7 is fixedly connected to an anti-slip pad 14. The middle of the lower block 2, the upper block 4, and the support block 9 are all slidably connected to a locking rod 31. One end of the locking rod 31 is slidably connected to the middle of the insert block 30. A stop block 33 is fixedly connected to the outer periphery of the locking rod 31. A compression spring 32 is sleeved on the outer periphery of the locking rod 31. A sliding plate 15 is fixedly connected to the end of the locking rod 31 away from the insert block 30. A pull rod 16 is fixedly connected to the outer side of the sliding plate 15. The anti-slip pad 14 is made of silicon carbide. The anti-slip pad 14 made of silicon carbide can increase the friction on the pipe 7, thereby ensuring the stability of the pipe 7 after it is fixed. At the same time, by pulling the lever 16, the sliding plate 15 is driven, which causes the locking lever 31 to slide out from the middle of the insert block 30. While the locking lever 31 is sliding, it will drive the stop block 33 to squeeze the compression spring 32, so that the anti-slip pad 14 can be removed and replaced, thereby avoiding the anti-slip pad 14 from being worn and affecting the fixing effect after long-term use.

[0038] Working principle: First, the rocker arm 11 drives the bidirectional threaded rod 20 to rotate, causing the two threaded blocks 21 on the outer periphery of the bidirectional threaded rod 20 to push the lower locking block 2 away through the inclined rod 12. At the same time, the bidirectional threaded rod 20 drives the ratchet 27 to rotate. After the rocker arm 11 is released, the ratchet 27 can be prevented from rotating in the same direction by the action of the spring plate 25 and the pawl 26. After the pipe 7 is fixed between the upper locking block 4 and the lower locking block 2, the pawl 26 is pressed to unlock the ratchet 27, so that the two lower locking blocks 2 are driven to move closer to each other under the push of the compression spring 28, thereby fitting the two pipes 7 together and preventing gaps from forming at the connection of the pipes 7.

[0039] By pulling the slide plate 15, the clamp rod 31 is pulled out from the middle of the insert block 30. At the same time, the clamp rod 31 will drive the stop block 33 to squeeze the compression spring 32, so that the anti-slip pad 14 can be disassembled and replaced after long-term use, thereby preventing the anti-slip pad 14 from weakening its fixing effect on the pipe 7 due to wear.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
