Description

Technical Field

[0001] This invention belongs to the field of temporary support structures for pipe bottoms, and in particular relates to an adjustable temporary support structure for pipe bottoms. Background Technology

[0002] In modern infrastructure construction, pipeline systems play a vital role. Whether it is urban water supply and drainage networks, oil and gas pipelines for energy transmission, or various material transmission pipelines in industrial production, the construction quality directly affects the safety, stable operation, and service life of the entire system. Pipeline construction involves multiple stages and numerous technical points, and needs to be completed under different geographical environments and complex engineering requirements. Among them, the support at the bottom of the pipeline is one of the key factors to ensure that the pipeline maintains the correct position and good condition during construction.

[0003] In traditional pipeline construction, the support of the bottom of the pipeline is often a simple and fixed method. This traditional support method has many limitations. Due to the complex and varied ground conditions of the construction site, such as unevenness, slope changes, and differences in the bearing capacity of different soil types, fixed-height supports are difficult to adapt to these changes and cannot ensure that the pipeline is at a relatively accurate elevation throughout the construction process. This can easily lead to pipeline installation deviations. In addition, after the pipeline is supported and fixed, there should be an appropriate distance between the pipelines to be welded. The distance should not be too long or too far to ensure the subsequent welding quality and efficiency. Therefore, corresponding measures are required. Summary of the Invention

[0025] The pipe moving assembly includes a groove 12 on the side wall of an arc-shaped positioning block 11. A first rotating shaft 13 is rotatably connected to the inner bottom surface of the groove 12. The first rotating shaft 13 is rotatably connected to the upper surface of the arc-shaped positioning block 11 via a bearing.

The side walls of the second limiting slider 28 are fixedly connected to the circumferential side walls of the connecting rod 24. The transmission component is located between the two pipe moving components. The first bevel gear 21 and the fourth bevel gear 26 are fixedly connected to the bottom ends of the two second rotating shafts 15 respectively. The two side walls of the two second limiting sliders 28 are respectively in contact with the inner walls of the two second strip-shaped limiting grooves 27. A rotating handle is fixedly connected to the top of any one of the two first rotating shafts 13 for easy operation by the staff. The two moving wheels 16 are respectively located in the two grooves 12.

[0026] The working principle of this invention is as follows:

[0027] During the installation of water supply pipelines, multiple temporary pipe bottom support structures are required for coordinated use. Each temporary pipe bottom support structure has a hydraulic cylinder below its crossbeam 4, which controls the height of the crossbeam 4, thus controlling the support height. During installation, the pipe to be installed is placed above the temporary pipe bottom support structure, between two arc-shaped positioning blocks 11. Then, by rotating the double-threaded rod 7, the two nuts 8 can only move left and right under the restriction of the first strip-shaped limiting groove 9 and the first limiting slider 10, thus engaging with the double-threaded rod 7. This causes the two nuts 8 to move left and right in opposite directions, controlling the two arc-shaped positioning blocks 11. The two arc-shaped positioning blocks 11 are used to clamp and fix the pipe to be installed, making it suitable for pipes of different diameters.

[0028] After supporting and fixing the two pipes to be welded, the connector between them is suspended between the two pipes. Multiple hydraulic cylinders below the support structure are controlled to align the two pipes with the ends of the connector. Then, a moving assembly is used to control the movement of the pipes, thereby aligning them with the ends of the connector and improving the quality of subsequent welding and installation. Taking one moving assembly as an example, rotating the handle rotates the first rotating shaft 13, which in turn drives the moving wheel 16 to rotate, causing the moving wheel 16 to contact the side wall of the pipe. Furthermore, through friction, the pipe can move on the supporting structure. The rotation of the first rotating shaft 13 drives the synchronous pulley 17 to rotate, which in turn drives the other synchronous pulley 17 and the second rotating shaft 15 to rotate through the meshing transmission of the synchronous belt 18. The rotation of the second rotating shaft 15 drives the first bevel gear 21 to rotate, which in turn drives the second bevel gear 22 and the transmission sleeve 23 to rotate through the meshing transmission. The rotation of the transmission sleeve 23 drives the connecting rod 24 and the third bevel gear 25 to rotate through the second strip-shaped limiting groove 27 and the second limiting slider 28. The rotation of gear 25 drives the fourth bevel gear 26 and another second rotating shaft 15 to rotate via meshing transmission, the principle being the same as described above. The rotation of the second rotating shaft 15 also drives the first rotating shaft 13 to rotate via the meshing transmission of the synchronous pulley 17 and the synchronous belt 18. This causes the first rotating shafts 13 of the two moving components to rotate simultaneously in opposite directions. The two first rotating shafts 13 drive the two moving wheels 16 to rotate in opposite directions. Through friction, this causes the pipe between them to move. This enables accurate control of the pipeline movement distance, which is beneficial to improving the efficiency and quality of subsequent installation. When the two arc-shaped positioning blocks 11 move, they will drive the transmission sleeve 23 and the connecting rod 24 to move through the mounting plate 14, the first connecting plate 19 and the second connecting plate 20. The connecting rod 24 will drive the two second limit sliders 28 to slide in the second strip-shaped limit groove 27. Thus, even if the two arc-shaped positioning blocks 11 move, the transmission component can still operate, thereby ensuring that the two moving wheels 16 can work normally and stably.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
