Description

Technical Field

[0002] In modern infrastructure construction, pipeline systems play a vital role. Whether it is the city's water supply and drainage network, oil and gas pipelines for energy transportation, or various material transmission pipelines in industrial production, the construction quality is directly related to the safety, stable operation and service life of the entire system. Pipeline construction involves multiple links and many 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 remains in the correct position and in good condition during the construction process.

[0003] In traditional pipeline construction, a relatively simple and fixed method is often used to support the bottom of the pipeline. This traditional support method has many limitations. Due to the complex and changeable ground conditions of the construction site, there are problems 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 located at a relatively precise elevation during the entire construction process, which can easily lead to pipeline installation deviations. At the same time, after the support and fixation of the pipeline are completed, the pipelines to be welded need to have a suitable distance between them, which should not be too long or too far, so as to ensure the subsequent welding quality and efficiency. Therefore, corresponding treatment measures are required. Summary of the invention

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

[0027] During the installation of the water supply pipe, multiple temporary support structures at the bottom of the pipe are required for use in conjunction, and when in use, a hydraulic cylinder is provided under the cross beam 4 of each temporary support structure at the bottom of the pipe, and the height of the cross beam 4 is controlled by the hydraulic cylinder, thereby realizing the control of the support height. During installation, the pipe to be installed is placed above the temporary support structure at the bottom of the pipe, between the two arc-shaped positioning blocks 11, and then the two-way threaded rod 7 is rotated by the knob, and the two-way threaded rod 7 rotates. The two nuts 8 can only move left and right under the restriction of the No. 1 strip limit groove 9 and the No. 1 limit slider 10, and then they will be threadedly engaged with the two-way threaded rod 7, so that the two nuts 8 move left and right in opposite directions, and the two arc-shaped positioning blocks 11 are controlled by the two nuts 8, and the two arc-shaped positioning blocks 11 are used to clamp and fix the pipe to be installed, which can be suitable for pipes of different diameters;

[0028] After the two pipes to be welded are supported and fixed, the joint between the two is suspended and hung between the two pipes to be welded, and the hydraulic cylinders under the multiple support structures are controlled so that the two pipes are aligned with the two ends of the joint, respectively. Then, a moving component is used to control the movement of the pipes so as to align with the two ends of the joint, thereby improving the quality of subsequent welding installation. Here, a moving component is taken as an example. The first rotating shaft 13 is rotated by turning the handle, and the rotation of the first rotating shaft 13 drives the moving wheel 16 to rotate, and the moving wheel 16 will contact the side wall of the pipe. Then, through friction, the pipeline can move on the supporting structure, the No. 1 rotating shaft 13 rotates to drive the synchronous wheel 17 to rotate, and then the meshing transmission of the synchronous belt 18 drives another synchronous wheel 17 and the No. 2 rotating shaft 15 to rotate, the No. 2 rotating shaft 15 rotates to drive the No. 1 bevel gear 21 to rotate, and the meshing transmission drives the No. 2 bevel gear 22 and the transmission sleeve 23 to rotate, the transmission sleeve 23 rotates through the No. 2 bar-shaped limit groove 27 and the No. 2 limit slider 28 to drive the connecting rod 24 and the No. 3 bevel gear 25 to rotate, and the No. 3 bevel gear 25 rotates. The rotation of the gear 25 drives the fourth bevel gear 26 and the other second shaft 15 to rotate through meshing transmission. The principle is the same as above. The rotation of the second shaft 15 will also drive the first shaft 13 to rotate through the meshing transmission of the synchronous wheel 17 and the synchronous belt 18, thereby making the first shafts 13 of the two moving components rotate at the same time, and the rotation directions are opposite. The two first shafts 13 will drive the two moving wheels 16 to rotate. The two moving wheels 16 rotate in opposite directions. Through friction, the pipeline between the two will move. This can achieve accurate control of the moving distance of the pipeline, which is beneficial to improving the efficiency and quality of subsequent installation. When the two arc-shaped positioning blocks 11 move, the transmission sleeve 23 and the connecting rod 24 will be driven to move through the mounting plate 14, the No. 1 connecting plate 19 and the No. 2 connecting plate 20. The connecting rod 24 will drive the two No. 2 limit sliders 28 to slide in the No. 2 strip limit groove 27. Even if the two arc-shaped positioning blocks 11 move, the transmission assembly 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 principle of the present invention should be included in the protection scope of the present invention.
