Technical Field

[0001] This utility model belongs to the technical field of pipe processing equipment, and in particular relates to a fixing device for quick pipe assembly. Background Technology

[0002] With the rapid development of China's economy and the increasing scale of large-scale petrochemical plants, pipeline welding has become a major technical aspect of chemical plant construction, requiring significant financial and material resources. Pipeline weld assembly is a crucial step in ensuring the quality of pipeline welding, and ensuring that the gap and joint precision of the pipeline joints meet welding requirements quickly before welding is currently a major challenge.

[0003] Currently, pipe weld assembly mostly relies on pipe fitters using measuring tools, chain hoists, or cranes for alignment. However, during the assembly process, it's difficult to quickly align pipes of different lengths, making it hard to guarantee the accuracy of the pipe alignment and, more importantly, the quality of the weld itself. Therefore, pipe weld assembly plays a decisive role in ensuring weld quality. Utility Model Content

[0010] Furthermore, the pipe clamping assembly includes a bidirectional lead screw, and a driving cavity is provided in the middle of the top wall of the mounting plate, in which the bidirectional lead screw is rotatably disposed.

[0011] Furthermore, a forward and reverse motor is provided on one side of the drive cavity, and the output shaft of the forward and reverse motor is connected to one end of a bidirectional lead screw.

[0012] Furthermore, the bidirectional lead screw is symmetrically threaded with clamping rods, the top of which slides in contact with the top wall of the drive cavity.

[0013] Furthermore, a sliding groove is provided in the lower center of the mounting plate, and the lower end of the clamping rod extends through the sliding groove to the bottom of the mounting plate. Clamping plates are symmetrically arranged at the lower ends of the two sets of clamping rods.

[0014] Furthermore, a bearing seat is provided in the middle of the drive cavity, which is used to support and limit the middle of the bidirectional lead screw.

[0019] 3. This utility model uses two adjusting brackets on the track to adjust the distance between the two ends of the pipe weld. Multiple adjusting brackets can also be set on the track. It is suitable for pipes of different lengths and positions. The adjusting brackets are fixed in the limiting hole with threaded pins to ensure stability.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] A typical embodiment of this utility model is as follows: Figure 1 As shown, a quick-assembly pipe fixing device includes a base 1, an adjusting frame 2, a pipe support 3, a mounting plate 8, and a pipe clamping assembly 4. The base 1 has guide rails 5 symmetrically arranged at both ends of its top. The adjusting frame 2 has guide slides 6 symmetrically arranged on both sides of its lower end, which are adapted to the guide rails 5. Two sets of adjusting frames 2 are provided, and the two sets of adjusting frames 2 are slidably mounted on the base 1 through the cooperation of the guide slides 6 and the guide rails 5. The pipe support 3 is located in the middle of the upper surface of the base 1 and inside the adjusting frame 2. Hydraulic telescopic rods 7 are symmetrically arranged on both sides of the upper end of the adjusting frame 2. The mounting plate 8 is slidably mounted on the adjusting frame 2 and its two ends are connected to the output shafts of the hydraulic telescopic rods 7. The pipe clamping assembly 4 is located on the mounting plate 8, directly above the pipe support 3. The pipe support 3 is a V-shaped pipe support 3. Roller grooves 9 are symmetrically arranged on both sides of the upper surface of the pipe support 3, and multiple sets of support rollers 10 are evenly distributed within the roller grooves 9. The pipe can be easily moved using the pipe support 3 and the multiple sets of support rollers 10.

[0028] The pipe clamping assembly 4 includes a bidirectional lead screw 11, a forward and reverse motor 12, clamping rods 13, and clamping plates 14. A drive cavity 15 is provided in the middle of the top wall of the mounting plate 8. The bidirectional lead screw 11 is rotatably disposed in the drive cavity 15. The forward and reverse motor 12 is disposed on one side of the drive cavity 15. The output shaft of the forward and reverse motor 12 is connected to one end of the bidirectional lead screw 11. The clamping rods 13 are symmetrically threaded onto the bidirectional lead screw 11. The top of the clamping rods 13 slides in contact with the top wall of the drive cavity 15. A sliding groove is provided in the lower middle of the mounting plate 8. The lower end of the clamping rods 13 extends through the sliding groove to the bottom of the mounting plate 8. The clamping plates 14 are symmetrically disposed at the lower ends of the two sets of clamping rods 13. The forward and reverse motor 12 drives the bidirectional lead screw 11 to rotate, thereby causing the clamping rods 13 to drive the clamping plates 14 to move towards each other, so as to clamp and fix pipes of different diameters.

[0029] The base 1 has symmetrical limiting holes 16 on both sides of the top. Multiple sets of limiting holes 16 are provided on the base 1 at intervals. The lower ends of both sides of the adjusting frame 2 are symmetrically provided with threaded plates 17. Threaded pins 18 are threadedly connected to the threaded plates 17. The threaded pins 18 are engaged with one of the limiting holes 16. The adjusting frame 2 can be moved to adjust the fixed position of the pipeline, and the adjusting frame 2 is fixed and limited by the threaded pins 18 being inserted into the corresponding limiting holes 16.

[0030] The clamp 14 is an arc-shaped clamp, and an anti-slip rubber pad 19 is fixedly connected to the clamp 14. This setting is beneficial for clamping the pipe securely.

[0031] A bearing seat 20 is provided in the middle of the drive cavity 15, and the bearing seat 20 supports and limits the middle of the bidirectional lead screw 11.

[0032] Working principle

[0033] When the pipeline needs to be processed and assembled, the pipeline is pushed in through the pipeline support 3. The two sets of adjustment brackets 2 are adjusted according to the length of the pipeline, so that they are moved to both ends of the pipeline or to both sides of the processing position. The adjustment brackets 2 are fixed by rotating the threaded pin 18 and screwing it into the corresponding limiting hole 16. The hydraulic telescopic rod 7 is started to drive the mounting plate 8 to move down, thereby moving the clamping plate 14 to the middle of both sides of the pipeline. The forward and reverse motor 12 is started to drive the bidirectional screw 11 to rotate, thereby causing the bidirectional screw 11 to drive the clamping plate 14 to move towards each other through the clamping rod 13 to clamp and fix both sides of the pipeline. At this time, the clamped and fixed pipeline can be processed. After processing, the pipeline can be removed from the pipeline support 3.

[0034] When processing two sets of pipes together, push the two sets of pipes from both ends of the pipe support 3 toward the middle so that the ends of the two sets of pipes are close together. Push the two sets of adjusting brackets 2 to the middle of the two sets of pipes or select a suitable fixed clamping position. Then rotate the threaded pin 18 to screw it into the corresponding limiting hole 16 to limit and fix the adjusting bracket 2. Start the hydraulic telescopic rod 7 to drive the mounting plate 8 to move down, thereby moving the clamping plate 14 to the middle of both sides of the pipe. Start the forward and reverse motor 12 to drive the bidirectional screw 11 to rotate, thereby causing the bidirectional screw 11 to drive the clamping plate 14 to move towards each other through the clamping rod 13 to clamp and fix both sides of the pipe. At this time, the two sets of pipes can be welded or processed. After processing, the pipes can be easily pushed out of the pipe support 3.

Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
