Abstract

A turning device for assisting in the welding of steel structure components, which relates to the technical field of steel structure component welding. In order to solve the problems that in the existing process of welding steel structure components, the cooperation of a crane is required to turn the steel structure components, this method cannot accurately control the rotation angle of the welded components, and has a relatively high noise and low welding efficiency. This structure uses the relative synchronous rotation of three pairs of cross wheels to assist in continuously turning over the welded steel structure components, so that multiple sides of the welded steel structure components can be continuously welded, greatly improving the welding efficiency. This turning device does not require the cooperation of a crane, and can also control the rotation angle of each pair of cross wheels by controlling the rotation angle of the output end of the turning drive motor. By controlling the rotation angle of one pair of cross wheels, the rotation angle of the welded steel structure component can be accurately controlled, and the noise is greatly reduced. The present invention is applicable to the technical field of steel structure welding machines.

During the production process of steel structure components, welding is an essential process. During the welding of steel structure components, the components of the steel structure need to be turned over multiple times to complete the welding of multiple surfaces. In particular, the turning over of components such as steel beams, steel columns, and box-shaped components during welding is very complicated, and it is necessary to use an overhead crane in the workshop to repeatedly hoist and turn over.

[0019] Then, place the two ends of the steel structure member at the right angles of the first pair of cross-shaped hubs 2-3 on the upper surface of the two turning platforms 2 respectively, and perform welding operations on the upper surface of the steel structure member to be welded. When the welding is completed, start the turning drive motor 2-13 and control the output shaft of the turning drive motor 2-13 to rotate 90°. The turning drive motor 2-13 drives the turning drive shaft 2-4 to rotate, thereby driving the cross-shaped hubs 2-3 at both ends of the turning drive shaft 2-4 to rotate, and then the steel structure member 5 to be welded can be turned. After the turning is completed, the other side of the steel structure member 5 to be welded can be welded. After the welding is completed, at this time, drive the transport drive motor 2-12.

[0020] Finally, repeat the above process, and use the transport drive motor 2-12 to reset the moving position of the transport plate 2-5, so that the steel structure member 5 to be welded can be continuously transported to the right angles of the cross-shaped hubs 2-3, and then use the rotation of the cross-shaped hubs 2-3 to turn and weld the four sides of the steel structure member 5 to be welded step by step; this structure can assist in continuously turning over the steel structure member 5 to be welded, so that the four sides of the steel structure member 5 to be welded can be continuously welded, greatly improving the welding efficiency. Without the cooperation of a crane, this structure can also control the rotation angle of the output end of the turning drive motor 2-13 to accurately control the rotation angle of the steel structure member to be welded, and greatly reduce the noise.

This turning-over device does not require the cooperation of a crane. Moreover, by controlling the rotation angle of the output end of the turning drive motor, the rotation angle of each pair of cross-shaped hubs can be controlled. In combination with the fact that a plurality of rollers are evenly arranged along the length direction at the tops of the two inner sides of the two inner side plates facing each other, and a transport plate is arranged between the two inner side plates, the bottom surface of the transport plate contacts the outer surface of the rollers, the third sprocket is connected to the second sprocket through a chain, and the middle of the bottom surface of the transport plate is fixedly connected to the upper surface of the chain. Furthermore, the transport drive motor can drive the transport plate to move horizontally between the two inner side plates, so as to realize the simultaneous horizontal movement of both ends of the steel structure member to be welded until it moves to the right-angle position on the outer surface of the cross-shaped hub. By controlling the rotation angle of one pair of cross-shaped hubs, the rotation angle of the steel structure member to be welded can be accurately controlled, and the noise is greatly reduced, and the welding safety is improved.

[0050] Then, place the two ends of the steel structure member on the right-angled corners of the first pair of cross-shaped hubs 2-3 on the upper surfaces of the two turning platforms 2 respectively, and perform welding operations on the upper surface of the steel structure member to be welded. When the welding is completed, start the turning drive motor 2-13 and control the output shaft of the turning drive motor 2-13 to rotate 90°. The turning drive motor 2-13 drives the turning drive shaft 2-4 to rotate, thereby driving the cross-shaped hubs 2-3 at both ends of the turning drive shaft 2-4 to rotate, and then the steel structure member 5 to be welded can be turned over. After the turning is completed, the other side of the steel structure member 5 to be welded can be welded. After the welding is completed; at this time, drive the transport drive motor 2-12. The transport drive motor 2-12 drives the drive shaft 2-9 to rotate.

The third sprocket 2-11 is connected to the second sprocket 2-10 through a chain, and the middle part of the bottom surface of the transport plate 2-5 is fixedly connected to the upper surface of the chain. Thus, the transport plate 2-5 can be driven to move horizontally between the two inner side plates 2-6, and the two ends of the steel structure member 5 to be welded can be horizontally moved simultaneously until they move to the right-angled corners on the outer surfaces of the next pair of cross-shaped hubs 2-3. At this time, stop driving the transport drive motor 2-12;

[0051] Finally, repeat the above process, and use the transport drive motor 2-12 to reset the moving position of the transport plate 2-5, so that the steel structure member 5 to be welded can be continuously transported to the right-angled corners of the cross-shaped hubs 2-3, and then use the rotation of the cross-shaped hubs 2-3 to turn over and weld the four sides of the steel structure member 5 to be welded step by step; this structure can assist in continuously turning over the steel structure member 5 to be welded, so that the four sides of the steel structure member 5 to be welded can be continuously welded, greatly improving the welding efficiency.
