Description

Technical Field

[0001] This utility model relates to the field of pipeline installation technology, and in particular to an auxiliary device for the installation of pipelines in chemical equipment. Background Technology

[0002] During the installation of large-diameter industrial pipelines for chemical equipment, the deviation in outer diameter caused by manufacturing tolerances of pipes and fittings, as well as the elliptic deformation that is prone to occur during transportation and hoisting of large-diameter pipes, bring great difficulties to the on-site welding assembly operation. Such assembly deviations will directly affect the welding quality and thus threaten the safe operation of the entire pipeline system.

[0003] Currently, the auxiliary devices commonly used in the installation of chemical equipment pipelines mainly employ simple jacks in conjunction with manual adjustments. However, this method is difficult to achieve precise alignment, cannot meet the high standards of welding process requirements, and cannot effectively compensate for misalignment caused by pipeline deformation and outer diameter deviation. This often results in a low weld assembly qualification rate and a high rework rate, requiring repeated trial adjustments, which prolongs the on-site installation cycle, increases construction costs, and may also affect the project schedule.

[0004] Therefore, given that the existing auxiliary devices are difficult to align precisely, resulting in low weld assembly pass rates, high rework rates, and the need for repeated adjustments, an auxiliary device for chemical equipment pipeline installation can be designed. This device will be adjustable to flexibly adjust the relative positions of the bolts, thereby achieving precise assembly. Utility Model Content

[0005] In order to overcome the problem that existing auxiliary devices are difficult to achieve precise alignment, resulting in low weld assembly qualification rate, high rework rate, and the need for repeated trial and adjustment.

[0006] The technical solution of this utility model is as follows: an auxiliary device for the installation of chemical equipment pipelines, used for the installation of pipelines and fittings, wherein the pipeline position is fixed and the fitting position is adjustable, including a reinforcing plate and an internal thread fixing seat. One end of the reinforcing plate is fixedly connected to the surface of the pipeline, and this end has an inwardly concave arc design with an inner diameter that matches the outer diameter of the pipeline. The internal thread fixing seat is disposed on one side of the reinforcing plate, and a second threaded post with a threaded connection is provided through the internal thread fixing seat. The tail end of the second threaded post points to the fitting port and abuts against the fitting surface. The position of the fitting is adjusted by rotating the second threaded post.

[0007] Preferably, the reinforcing plate fits tightly against the outer surface of the pipe through its concave arc end, ensuring a stable connection of the device. Tightening the second threaded post in the internal threaded fixing seat causes the second threaded post to abut against the pipe fitting, which is used to adjust the deviation between the pipe and the pipe fitting.

[0008] Preferably, the internal threaded fixing seat and the reinforcing plate are welded or integrally formed.

[0009] Preferably, the reinforcing plate is movably connected to the internal threaded fixing seat via a lateral adjustment assembly.

[0010] Preferably, the lateral adjustment assembly includes a clamping plate and a movable support plate. The clamping plate is fixedly connected to the reinforcing plate, and the movable support plate is connected to the clamping plate through a first threaded post. The first threaded post passes through the movable support plate and is fixed on both sides by adjusting nuts. The movable support plate has a concave arc-shaped surface at one end near the pipe fitting, and an anti-slip pad is installed inside it. The inner diameter of the anti-slip pad is adapted to the outer diameter of the pipe fitting.

[0011] Preferably, ribs and reinforcing bars are provided between the reinforcing plate and the clamping plate.

[0012] Preferably, the head of the second threaded column is fixedly connected to a limited seat.

[0013] Preferably, the tail end of the second threaded column is provided with a soft pad that abuts against the pipe fitting, and an insert is inserted into the limiting seat, with limiting plates fixedly connected to both ends of the insert.

[0014] The beneficial effects of this utility model are as follows: The precise threaded engagement between the internal threaded fixing seat and the second threaded column allows for micron-level position adjustment by rotating the second threaded column, ensuring precise alignment of the pipe fitting and pipeline axis. This significantly improves the first-pass yield of weld assembly, reduces subsequent rework, and ensures the reinforcing plate fits snugly against the pipeline through its concave arc end, guaranteeing stable installation and preventing misalignment during adjustment. Furthermore, the linear advancement mechanism of the second threaded column makes pipe fitting position adjustment more linear and controllable, allowing operators to make fine adjustments according to actual needs without repeated disassembly or trial and error, greatly improving installation efficiency. The length and stroke of the second threaded column can be flexibly selected according to the pipe fitting size, requiring only one person to operate. Precise positioning can be achieved by rotating the second threaded column, significantly reducing reliance on skilled workers, minimizing manpower and time costs, ensuring the pipe fitting and pipeline connection meets process standards, and reducing safety hazards caused by installation errors.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] The auxiliary device of this invention is not only suitable for the installation of chemical equipment pipelines, but can also be applied to the installation of oil, natural gas, water supply and drainage, heating, ventilation and air conditioning (HVAC) and other industrial pipeline systems.

[0022] Example 1

[0023] Please see Figure 1 This utility model provides an embodiment: an auxiliary device for the installation of chemical equipment pipelines, used for the installation of pipelines 10 and fittings 11, wherein the position of pipeline 10 is fixed and the position of fitting 11 is adjustable, including a reinforcing plate 4 and an internal thread fixing seat 31. One end of the reinforcing plate 4 is fixedly connected to the surface of pipeline 10, and this end has an inwardly concave arc design, with the inner diameter matching the outer diameter of pipeline 10. The internal thread fixing seat 31 is disposed on one side of the reinforcing plate 4, and a second threaded post 32 with a threaded connection is provided through the internal thread fixing seat 31. The tail end of the second threaded post 32 points to the port of fitting 11 and abuts against the surface of fitting 11. The position of fitting 11 is adjusted by rotating the second threaded post 32. The internal thread fixing seat 31 and the reinforcing plate 4 are welded or integrally formed, and the head of the second threaded post 32 is fixedly connected to a limiting seat 7.

[0024] Chemical pipeline systems typically need to withstand high pressure, high temperature, and corrosive media, requiring extremely high welding quality and installation precision. This device, through the precision adjustment function of the second threaded post 32, can achieve a centering accuracy of 0.1mm, ensuring the quality of weld assembly and effectively avoiding stress concentration and media leakage risks caused by misalignment. Furthermore, chemical equipment pipelines are generally compact, making it difficult to use large auxiliary devices. This device occupies little space and is particularly suitable for precise installation in confined spaces. The reinforcing plate 4 fits tightly against the outer surface of the pipe 10 through its concave arc end, ensuring a stable connection of the device. By turning the second threaded post 32 inside the internal threaded fixing seat 31 through the limit seat 7, the second threaded post 32 abuts against the pipe fitting 11, which is used to adjust the deviation between the pipe 10 and the pipe fitting 11.

[0025] Example 2

[0026] Please see Figure 2This utility model provides an embodiment: an auxiliary device for the installation of chemical equipment pipelines. The difference from embodiment 1 is that the reinforcing plate 4 is movably connected to the internal threaded fixing seat 31 through a lateral adjustment component. The lateral adjustment component includes a clamping plate 1 and a movable support plate 22. The clamping plate 1 is fixedly connected to the reinforcing plate 4. The movable support plate 22 is connected to the clamping plate 1 through a first threaded post 21. The first threaded post 21 passes through the movable support plate 22 and is fixed on both sides by adjusting nuts 23. The movable support plate 22 has a concave arc-shaped surface at one end near the pipe fitting 11, and an anti-slip pad 24 is installed inside it. The inner diameter of the anti-slip pad 24 is adapted to the outer diameter of the pipe fitting 11. Ribs 5 and reinforcing ribs 6 are provided between the reinforcing plate 4 and the clamping plate 1.

[0027] Ribs 5 and reinforcing ribs 6 are used to strengthen the structural strength between the reinforcing plate 4 and the clamping plate 1. The arc-shaped end of the movable support plate 22 is brought close to the pipe fitting 11 so that its anti-slip pad 24 contacts the outer wall of the pipe fitting 11. The position of the movable support plate 22 is adjusted and fixed by the first threaded post 21 and the adjusting nut 23. The distance between the movable support plate 22 and the port of the pipe fitting 11 is adjusted to stabilize the support of the pipe fitting 11.

[0028] Example 3

[0029] Please see Figure 3 This utility model provides an embodiment: an auxiliary device for the installation of chemical equipment pipelines. The difference from embodiment 1 is that the tail end of the second threaded column 32 is provided with a soft pad 34 that abuts against the pipe fitting 11, and an insert 8 is inserted into the limiting seat 7. Both ends of the insert 8 are fixedly connected to the limiting plate 9.

[0030] The second threaded post 32 can be rotated more effortlessly by inserting the post 8, allowing it to move axially within the internal threaded fixing seat 31.

[0031] Example 4

[0032] Please see Figure 4 This utility model provides an embodiment: an auxiliary device for the installation of chemical equipment pipelines. The difference from embodiment 2 is that the tail end of the second threaded column 32 is provided with a soft pad 34 that abuts against the pipe fitting 11, and an insert 8 is inserted into the limiting seat 7. Both ends of the insert 8 are fixedly connected to the limiting plate 9.

[0033] The soft pad 34 abuts against the surface of the fitting 11, which increases the friction while reducing damage to the surface of the fitting 11.

[0034] Through the above steps, the precision thread engagement between the internal threaded fixing seat 31 and the second threaded post 32 allows for micron-level position adjustment by rotating the second threaded post 32. This ensures precise alignment of the pipe fitting 11 with the axis of the pipe 10, significantly improving the first-pass yield of weld assembly and reducing subsequent rework. The reinforcing plate 4, with its concave arc-shaped end, fits tightly against the pipe 10, ensuring stable installation and preventing misalignment during adjustment. Furthermore, the linear advancement mechanism of the second threaded post 32 makes the position adjustment of the pipe fitting 11 more linear and controllable, allowing operators to adjust according to actual needs. Fine-tuning eliminates the need for repeated disassembly and trial and error, significantly improving installation efficiency. The length and stroke of the second threaded post 32 can be flexibly selected according to the size of the pipe fitting 11. Only one person is required to operate it. Precise positioning can be completed by rotating the second threaded post 32, which significantly reduces the reliance on skilled workers, reduces manpower input and time costs, ensures that the connection between the pipe fitting 11 and the pipeline 10 meets the process standards, and reduces safety hazards caused by installation errors. This solves the problem that existing auxiliary devices are difficult to achieve precise alignment, resulting in low weld assembly qualification rate, high rework rate, and the need for repeated trial and adjustment.

[0035] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
