Abstract
Description
Technical Field
[0001] The invention relates to the technical field of pipeline construction, and in particular to an automatic leveling welding work frame for installing clean pipelines. Background Art
[0002] At present, the process pipeline construction in pharmaceutical engineering generally adopts fully automatic argon arc welding machine for welding. The welding quality of the weld determines the product quality of the whole process system. Often in the daily construction process, the weld assembly process of the parent material at both ends is very critical. Because the process pipeline is installed and inserted after the space division and forming of the civil engineering project, the welding operation site is often selected at the construction site. Affected by the site, the weld assembly depends entirely on the naked eye observation of the operator and the rough level measurement with a level ruler. The parallelism of the weld assembly cannot be guaranteed, so secondary grinding and rework are required, resulting in a large waste of manpower and financial resources. The current situation of poor control of the parallelism of the weld assembly has greatly affected the efficiency of the construction site.
[0003] Therefore, there are areas in the existing pipeline welding construction that need to be improved urgently. The horizontal control of the welded pipeline should be improved to meet the parallelism requirements of the construction process. Therefore, a more reasonable technical solution needs to be proposed to solve the shortcomings of the existing technology. Summary of the invention
[0004] In order to solve the defects of the prior art mentioned above, the present invention provides an automatic leveling welding workbench for clean pipeline installation, which greatly improves the parallelism of the pipeline to be welded by automatically leveling the pipeline to be welded. The parallelism of the pipeline is set to the required level before welding, thereby improving the accuracy of the welding process and reducing rework and waste of resources.
[0005] In order to achieve the above object, the technical solution specifically adopted by the present invention is:
[0006] An automatic leveling welding workbench for clean pipeline installation comprises a support frame, the support frame comprises a fixed portion, at least three support legs with adjustable inclination angle and length are arranged below the fixed portion; a leveling device is arranged on the fixed portion, a connecting portion is arranged on the top of the leveling device, and a supporting piece for placing a pipe fitting to be welded is arranged on the connecting portion.
[0007] The above disclosed working frame, by setting a support frame as a supporting structure, can be set up in various terrains and provide stable support with its support legs with adjustable tilt angle and length; the fixing part is used to connect and fix the leveling device for leveling, ensuring that the set pipe to be welded is kept at the required precise level. The above disclosed working frame can realize the precise alignment and connection of adjacent pipes, ensure the parallelism of pipe connection, reduce welding errors, and thus improve the efficiency of pipe connection.

When such a solution is adopted, the supporting leg can be fixed to the ground to prevent the supporting leg from sliding and causing the bracket to be unstable.
[0013] Furthermore, the leveling device used in the present invention can be of various types, and its structure is not limited to a single one. Here, optimization is performed and one feasible option is given: the leveling device includes an infrared leveler. When such a solution is adopted, the infrared leveler can automatically adjust according to the height of the infrared leveler of the adjacent workbench, so that the two adjacent infrared levelers are adjusted to the same horizontal height, so that the pipes to be welded are kept at the same height, ensuring the welding accuracy.

[0026] In view of the current situation that the existing pipeline welding work frame is fixed after being erected, it is difficult to adjust the height and cannot improve the parallelism of the welded pipeline. This embodiment discloses a work frame for improving the parallelism of the pipeline to be welded.
[0027] Specifically, the technical solution adopted in this embodiment is as follows:

The above disclosed working frame can realize the precise alignment and connection of adjacent pipes, ensure the parallelism of the pipe connection, reduce the welding error, and thus improve the efficiency of pipe connection.
[0030] The support frame structure can adopt a variety of structures composed of adjustable support legs 10, which is not limited to the only one. In some embodiments, the support legs 10 can be constructed as threaded telescopic, hydraulic telescopic and other structures, and the height of the fixed part 6 can be raised and lowered to a certain extent. This embodiment is optimized and adopts one of the feasible options: a telescopic part is set below the fixed part 6, and the support leg 10 is connected to the lower end of the telescopic part. When such a solution is adopted, the height of the fixed part 6 can be raised or lowered through the telescopic effect of the telescopic part, and the height of the final pipe to be welded can be roughly adjusted, thereby reducing the time spent by the leveling device 5 in setting the height and improving the efficiency of pipe welding.

Specifically, the limiting groove can be arranged on the axial telescopic rod, and the limiting strip can be arranged on the inner wall surface of the cylinder 9.
