Description

Technical Field

[0001] The utility model relates to the technical field of boiler manufacturing, in particular to a welding device for boiler manufacturing which is convenient for adjusting the height. Background Art

[0002] A boiler is an energy conversion device. The hot water or steam generated in the boiler can directly provide the required thermal energy for industrial production and people's lives. It can also be converted into mechanical energy through a steam power device, or the mechanical energy can be converted into electrical energy through a generator. Welding is required during the assembly of the boiler. Due to the large size of the boiler, the device for welding the boiler needs to be able to adjust the height to assist manual welding.

[0003] For example, a welding device for boiler manufacturing with an easily adjustable height is disclosed in the utility model with the authorization announcement number CN219725013U. By setting a lifting device, the height of the workbench can be adjusted by pushing the upper supporting legs up and down by the connecting rod. By setting a clamping device, the clamping device can clamp boilers of different sizes.

[0004] This prior art also has the following problems when used:

[0005] The device adjusts the height of the workbench through a lifting device. Due to the good self-locking performance of the gear, the connecting rod is not easy to shake, but it is difficult for the connecting rod to limit the position of the upper supporting leg. When the worker is welding on the workbench, the workbench and the upper supporting leg are easy to move upward and vibrate up and down, thereby reducing the stability of the workbench and affecting the welding effect. In the process of clamping the boiler by the clamping device, the third gear rotates to drive the connecting plates closer to each other. At the same time, the left gear approaches the connecting plate on the other side, which will hinder the connecting plate from continuing to move, thereby reducing the applicability of the device to the boiler size.
