Description

Technical Field

[0001] The utility model relates to a support, in particular to a temporary support for processing a pipeline with a variable diameter, which is mainly used for position-limiting support of the pipeline and belongs to the technical field of auxiliary products for building construction. Background Art

[0002] Generally speaking, the use of temporary supports is very important in the process of metal pipe processing. Temporary supports can ensure the stability and accuracy of pipes during cutting, welding, assembly and other processes, thereby improving the quality and efficiency of pipe manufacturing. In addition, during the transportation and installation of pipes, temporary supports can also be used to support and fix pipes to prevent them from moving or deforming.

[0003] In conventional construction sites, most pipeline processing generally does not use temporary supports and is usually carried out on the ground. This method of operation not only makes it difficult to ensure processing quality, but also requires additional workers to assist in moving and flipping the pipeline, resulting in extremely low construction efficiency.

[0004] After searching, the Chinese invention patent with the current patent announcement number of CN 108057752 A discloses a steel pipe flat bracket for a groove rolling machine, including a base, a support leg fixedly installed at the lower end of the base, a lifting rod movably installed through the base, a mounting plate vertically provided at the upper end of the lifting rod, and a pipe support frame slidably installed at both ends of the mounting plate. Although this patent can also support the pipeline and adjust the height according to needs, there will still be problems during use. Since the structure used for adjustment adopts an elongated hole to support different pipeline diameters by moving left and right, this structure still has unstable fixation. Since the pipeline is supported and fixed for a long time, the adjustment bolt is easy to loosen in the adjustment elongated hole, which leads to the easy shaking of the pipeline when supporting it. When supporting the pipeline, since the area used to support the pipeline is only supported by the rollers on both sides, the contact area between the pipeline and the bracket is small, the stability is poor, and the entire support seat will shake. In short, it is often very inconvenient.

[0005] Therefore, the key to solving the above technical problems is to develop a temporary support for variable diameter pipeline processing with strong practicality and high working reliability. Summary of the invention

[0006] In view of the many defects and deficiencies in the above-mentioned background technology, the present invention has made improvements and innovations thereto, aiming to provide a device with simple structure, novel and reasonable design, and stronger stability, and the use of this device can ensure the stability and accuracy of the pipeline in the processes of cutting, welding, and assembly, thereby improving the quality and efficiency of pipeline manufacturing.

[0075] In summary, a more specific implementation method of the present invention is:

[0076] Before using the temporary support for processing a pipe with a variable diameter of the above-mentioned design structure, it is necessary to manufacture and install it as a backup.

[0077] The specific production steps are:

[0078] First, use L40*4 angle steel to make three legs 13 of equal length. The height of the legs 13 is preferably 100mm to 200mm. To ensure the stability of the support 1, the cut surface can be made into an oblique cut appropriately, but it is necessary to ensure that the two end surfaces of the legs 13 are parallel and the cut surfaces of the three legs 13 are consistent;

[0079] Then, use a cutter or a cutting machine to cut the 10 mm thick steel plate into an equilateral triangle with a side length of 300 mm to form a support platform 12. To avoid sharp corners from hurting people, the three sharp corners can be ground into arcs;

[0080] Secondly, find the center of the equilateral triangle steel plate, and according to the diameter of the adjustable support rod 2, this description takes the M30 screw as an example, and uses mechanical drilling to make a Φ30 circular hole, which is the mounting hole 11. To ensure that the screw can normally penetrate the steel plate without shaking left and right, the diameter of the circular hole should be 2-5mm larger than the diameter of the screw;

[0081] Next, make the pipe support jack 3. Use a 5mm thick plate, cut and weld it as shown in the figure, and mechanically open holes at the corresponding positions to facilitate the installation of the guide support 32. In the utility model, the guide support 32 is a roller bearing;

[0082] Next, weld one end of the adjusting screw vertically to the center of the base, insert the base and the adjusting screw into the support steel plate, and fix them with nuts up and down to achieve free adjustment of the upper and lower heights.

[0083] Finally, according to the outer diameter of different pipes 4, guide support members 32 are installed at corresponding positions, and connected with shafts 33 or fixed with latches as needed to meet the processing requirements of pipes 4 with different diameters, i.e., between DN80 and DN200. After production is completed, they can be installed.

[0084] During installation, the operator only needs to place the support structure of the utility model relative to the length of the pipe to be processed or supported. Figures 1 to 3 As shown, the operator only needs to manually lift the pipe 4 to be processed or supported onto the utility model, and place the pipe 4 on the pipe support top bracket 3. The operator selects to place the pipe 4 on the corresponding groups of guide support members 32 installed at different positions according to the diameter of the pipe for support. At the same time, other unnecessary groups of guide support members 32 can be selectively removed according to actual needs, so that the position-limiting support of the pipe 4 can be achieved through a group of guide support members 32 arranged relatively, and the pipe 4 can be used after the support is stable and reliable.

[0085] When in use, the operator only needs to perform corresponding processing or supporting work on the pipe supported by the utility model. When welding the pipe 4, due to the provided guide support 32, the pipe 4 can be flexibly rolled and flipped, so that the pipe can be processed easily and quickly; during the processing, the operator can adjust the adjustable support rod 2 of the utility model according to the required height, and simultaneously adjust the height of the pipe support top support 3 by lifting and lowering the adjustable support rod 2 in the mounting hole 11. After the lifting and adjustment is to the appropriate position, the operator only needs to fasten the upper and lower ends of the adjustable support rod 2 through the anti-slip fastener 21.

[0086] Finally, as time goes by, when the construction is completed, the operator only needs to clean and repair the various components of the utility model, and then move them to the designated tool storage warehouse for storage by manual or corresponding handling equipment, so as to prepare for the next cycle of use.

[0087] Finally, it should be noted that the above is only a preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the content of the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
