Description

Technical Field

[0001] The utility model relates to the technical field of welding automation equipment, in particular to a welding trolley and a T-shaped floor welding device. Background Art

[0002] When producing refrigerated containers, welded T-shaped floors are usually used as the floors inside the refrigerated containers to increase the air conduction inside the refrigerated containers. Since the welds of the T-shaped floors are parallel, regular long straight seams, in order to improve welding efficiency and welding quality, it is necessary to design special welding devices to provide convenient capabilities for T-shaped floor welding technology.

[0003] The T-shaped floor of a refrigerated container is generally made of aluminum alloy. When used in a refrigerated container, the area to be welded is also large according to the area required inside the refrigerated container. Therefore, multiple T-shaped materials need to be welded side by side. In the prior art, the T-shaped floor is generally welded on the surface of the T-shaped material. It is necessary to rely on a contour wheel to press the T-shaped material to control the height of the welding gun to align with the weld. The height cannot be freely controlled, and the welding switch is on the welding gun. During welding, the workpiece is required to be fixed and the welding gun is moved by hand, resulting in low welding efficiency and unstable welding, and prone to uneven thickness, perforation, and biased welding.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] 1. The T-type floor welding device, by arranging welding components on the welding trolley, enables the welding trolley to have multiple sets of welding gun mechanisms, which can automatically weld multiple sets of T-shaped bars placed side by side during the movement of the trolley, thereby reducing the consumption of human resources and greatly improving the welding efficiency of the T-type floor. At the same time, the movement of the trolley is controlled by a motor, so that the welding can be promoted only by moving along a fixed track, wherein the welding gun mechanism has the ability of automatic welding controlled by the background, thereby improving the automation effect of the welding device.

[0020] 2. The T-type floor welding device, through the welding gun mechanism arranged on the welding assembly, does not need the welding gun mechanism to be attached to the weld for welding, so that the welding gun mechanism has the ability to adjust.

Automatic compensation and correction can be performed through the lateral adjustment module and the longitudinal adjustment module, which increases the intelligent effect of the welding device during welding and improves the welding quality.

[0021] 3. The T-type floor welding device, by setting a power component, enables the welding trolley to have the ability to move autonomously, and can remotely control the welding progress of the welding trolley to realize unmanned welding technology, and then cooperate with the intelligent control component of the welding gun mechanism set on the welding component to reduce the demand for manpower.

[0022] 4. The T-shaped floor welding device flattens the T-shaped bar placed on the welding device through the clamping mechanism arranged on the welding trolley, so that the welding part of the T-shaped bar is pressed and fixed. Even if the welding assembly is suspended above the T-shaped bar to apply welding force, the stability of the T-shaped bar during welding can be maintained, so that the size of the weld after welding is uniform and presents a straight thin line, without perforation, biased welding, etc. BRIEF DESCRIPTION OF THE DRAWINGS
