A positioning welding device for catalytic tower plates

Abstract

The invention discloses a catalytic tower plate positioning welding device, which comprises a tower wall positioning unit, a plate positioning unit, a welding unit, and a support frame. A square hole is arranged in the middle of the plate on the support frame, and the tower wall positioning unit is installed on the support frame. In the middle position, the bottom of the tower wall positioning unit is tightly connected with the lower plate of the support frame, and the upper part of the tower wall positioning unit protrudes from the square hole. There are two sets of plate positioning units, and the two sets of plate positioning units are respectively located on both sides of the support frame. , the bottom of the plate positioning unit is fastened to the top of the support frame, and the welding unit is installed on the plate positioning unit. The tower wall positioning unit can accurately position the annular tower walls of different lengths and diameters, and the plate positioning unit can automatically load and position the plates, ensuring the accuracy of welding. The welding unit operates synchronously through the rotation of three sets of welding torch components, and performs segmental welding on the welding parts, which greatly improves the working efficiency of the device.

Description

technical field [0001] The invention relates to the technical field of automatic welding, in particular to a positioning welding device for catalyst tray sheets. Background technique [0002] The catalyst tower is usually a cylindrical plate structure tower. Various catalysts are placed on different layers of trays. The raw materials enter the tower from the top of the tower and exit the tower from the bottom of the tower. The plate welding of the catalyst tower is to weld the circular plate into a ring-shaped tower wall, usually by manual welding, but due to the large size of the catalyst tower wall and plate, manual welding will cause harm to workers produce a greater physical burden. In order to solve this problem, automatic welding machines for catalytic tower plates have begun to appear, but the traditional plate welding machines have low work efficiency, and the positioning accuracy of tower walls and plates is low, and welding errors are prone to occur. On the other...

Problems solved by technology

The plate welding of the catalyst tower is to weld the circular plate into a ring-shaped tower wall, usually by manual welding, but due to the large size of the catalyst tower wall and plate, manual welding will cause harm to workers greater physical burden

In order to solve this problem, automatic welding machines for catalytic tower plates have begun to appear at present, but the work efficiency of traditional plate welding machines is low, and the positioning accuracy of tower walls and plates is low, and welding errors are prone to occur

On the other hand, traditional welding equipment cannot automatically load and unload the plates, and requires manual assistance, which increases labor costs

The speed of traditional welding equipment is usually constant when the welding wire is fed. When encountering unqualified welding wire, the device cannot adjust the feeding speed of the welding wire in time, resulting in insufficient or excessive welding wire at the welding position, which affects The effect of welding
