Description

Technical Field

[0001] The utility model relates to the technical field of flange welding, in particular to a flange welding workbench. Background Art

[0002] A pipeline is a device connected by pipes, pipe connectors and valves for conveying gas, liquid or fluid with solid particles. Usually, after the fluid is pressurized by a blower, compressor, pump and boiler, it flows from the high pressure part of the pipeline to the low pressure part. It can also be conveyed by the pressure or gravity of the fluid itself. The use of pipelines is very wide, mainly used in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices. At present, when the pipeline is used, it is generally necessary to weld flanges or pipe fittings at both ends of the pipeline, and then connect the pipeline through the flange for use. At present, in the process of welding flanges and pipelines, the flange is generally spot welded to the pipeline first, and then the welding staff further welds the connection between the pipeline and the flange on the ground. Due to the obstruction of the ground, the welding staff can only weld the connection between the pipeline and the flange that is not obstructed by the ground. After that, the pipeline needs to be rolled to expose the connection between the pipeline and the flange that was originally obstructed by the ground. The welding staff further welds the pipeline and the flange. The welding of the pipeline and the flange is completed by a week of welding.

[0003] The existing technology has the following problems:

[0004] After searching, Chinese patent publication number: CN212070950U discloses a semi-automatic pipeline welding workbench, including: a support frame; a first rolling device, arranged on the support frame, used to drive the target pipeline to roll, and having: a first rolling member, which can be rotatably arranged to support the target pipeline; a second rolling member, which is arranged in parallel with the first rolling member and supports the target pipeline together with the first rolling member; a first driving member, which is transmission-connected with the first rolling member and the second rolling member, and is used to drive the first rolling member and the second rolling member to rotate, thereby driving the target pipeline to rotate. When the patent is used, one end of the target pipeline is placed on the first rolling member and the second rolling member, and the other end is placed on the first driven wheel and the second driven wheel. The first driving member drives the first rolling member and the second rolling member to rotate, thereby driving the target pipeline to rotate. The presence of the first driven wheel and the second driven wheel at the other end can make the pipeline easier to rotate while supporting the pipeline. At the connection between the pipeline and the flange, the staff can stand in one position to perform a complete welding of the pipeline and the flange as the pipeline and the flange rotate, thereby improving the welding efficiency.

[0005] However, there are still problems that need to be improved in the actual welding process of the target pipeline. The most obvious one is the single welding station, and the welding efficiency of the pipeline and the flange needs to be improved.

[0006] To this end, we proposed a flange welding workbench to solve the above-mentioned drawbacks. Utility Model Content

After that, the pipe needs to be rolled to expose the connection between the pipe and the flange that was originally obstructed by the ground, and the welding staff further welds it to complete the welding of the pipe and the flange by welding the connection between the pipe and the flange for a week.

[0026] In this embodiment: a control panel 14 is fixedly mounted on the top surface of the workbench 1 , and the control panel 14 is electrically connected to the reduction motor 10 and the synchronous motor 6 through wires.

It belongs to the common knowledge in this field. It is only used without modification, so the control method and circuit connection are not described in detail.

[0037] Working principle: When in use, refer to a semi-automatic pipe welding workbench disclosed in Chinese Patent Publication No.: CN212070950U. First, adjust the distance between the two support members 4 in each group of support components according to the length of the pipe. Use the screw module to adjust the distance between the two support members 4 in each group of welding stations, so that pipes of different lengths can be supported, which is convenient for flange welding of pipes of different lengths. The scope of application is wider, the practicability is strong, and it is worth promoting. Then, multiple target welding pipes 12 with welding are placed on each group of welding stations respectively. By setting multiple welding stations, multiple pipe flanges can be welded at the same time, which improves the welding efficiency of pipe flanges. It is practical and worth promoting. During the welding process, the reduction motor 10 drives the worm 11 to rotate, and the worm 11 rotates to drive the worm wheel 9 to rotate, so that the rolling wheel 8 follows the rotation, and the target welding pipe 12 can be rotated. At the connection between the pipe and the flange, the staff can stand in one position to perform a complete welding of the pipe and the flange as the pipe and the flange rotate, thereby improving the welding efficiency.
