Background

The welding of the tank body generally comprises the welding of parts such as straight seams, circular seams and the like of the tank body, after one side of a product is welded, the product is usually required to be manually rotated, and then the product is welded again, so that the mode is time-consuming and labor-consuming, and particularly when a large product is required to be welded, the operation is very inconvenient, the work is assisted by other clamping equipment, the overall efficiency is low, and a certain safety risk is involved.

In order to solve the above technical problems, in the prior art, for example, chinese patent publication No. CN213998283U discloses a tank tracking welding apparatus, which includes a cantilever mechanism and a rotary positioning mechanism (i.e., a supporting device), where the cantilever mechanism is disposed on one side of the rotary positioning mechanism, the cantilever mechanism includes a movable bottom plate, a cantilever mounting plate movably connected to the movable bottom plate is disposed on the movable bottom plate, and a welding head is disposed on the cantilever mounting plate.

However, since the positioning plate of the device cannot be rotated and inclined, the welding seam at the position still needs to be manually turned to a horizontal state for inclined welding seams, and then welding is performed by using devices such as a welding gun, or manual welding is performed for the welding seam at the position, so that the device is very inconvenient in actual production, has low production efficiency, and cannot meet the welding requirements of different welding seams of a tank body.

When girth welding is required, the motor 231 is started to enable the two driving wheels 211 to rotate synchronously, so that the tank body rotates at a constant speed, the welding gun is moved to a welding position and kept motionless until girth welding is completed, and the tank body rotating at the constant speed can ensure that the welding quality of each part of the welding seam is consistent, and the welding effect is ensured.

When the welding of the inclined weld joint is required, the lifting screw rod 32 is driven to rotate by the rotation of the hand wheel 33, the support frame 12 is driven to rotate, the welding is stopped after the welding is adjusted to a proper angle, the welding gun is used for completing the welding of the inclined weld joint, and the positioning wheel 4 can rotate along with the rotation of the tank body, so that larger friction is avoided.

Example 2: the embodiment provides a different rotary support assembly, unlike embodiment 1, in this embodiment, the rotary support assembly includes two three-jaw chucks disposed on two lateral sides of the support frame relatively, one of the three-jaw chucks is connected with a driving motor, the other three-jaw chuck is rotatably mounted on a rotating shaft through the driving motor, and the rotating shaft is rotatably mounted on the support frame through a bearing seat, so that two ends of the tank body can be clamped and supported by the two three-jaw chucks, the tank body is driven to rotate by the driving motor, and the three-jaw chucks form a positioning and retaining structure for preventing the tank body from sliding.

Example 3: the present embodiment provides a different lifting assembly, unlike embodiment 1 in which the lifting assembly is a hydraulic cylinder, the cylinder body of which constitutes the support cylinder body, and the piston rod of which constitutes the telescopic rod.

Example 4: the present embodiment provides a different lifting assembly, unlike embodiment 1 in which, in this embodiment, one end of the support sleeve facing away from the telescopic rod is fixedly mounted on the bottom frame, one end of the telescopic rod facing away from the support sleeve is hinged with a slider, and a groove adapted to the slider and extending transversely is provided on the support frame, so that the support frame can also be rotated by lifting the telescopic rod.

In the embodiment of the tank welding deflection supporting device, the structure of the tank welding deflection supporting device is the same as that of the tank welding deflection supporting device in the tank welding deflection equipment, and the description is omitted herein.

The foregoing is merely a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and variations may be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
