Problems solved by technology

This manual welding construction has the following disadvantages: 1. The labor intensity of the workers is relatively large; 2. The asynchronous welding construction of the four welds has low welding efficiency, and the welding stress of each weld is relatively large, which is prone to welding. Deformation affects the welding quality; 3. During manual welding, the main girder of the crane must be turned over with a turning device. Manufacturing cost of the main beam

Abstract

The invention relates to a crane main beam welding machine. The crane main beam welding machine comprises a fixed mount, a movable frame which is arranged on the fixed mount along horizontal direction in a guiding manner, the crane main beam welding machine further comprises a movable frame driving device which is in transmission connection with the movable frame and drives the movable frame to do reciprocating motion along the horizontal direction, and the movable frame is provided with a welding fun which is used for conducting welding construction on a position to be welded of a crane main beam. The invention provides a crane main beam welding machine which can lighten the labor intensity of workers in welding and manufacturing of the crane main beam.

Description

technical field [0001] The invention relates to a crane main girder welding machine used for crane main girder manufacturing. Background technique [0002] The main girder of the crane includes a beam box with a U-shaped groove in cross section, side plates respectively arranged at the edges of the notches on both sides of the beam box, and an I-beam set between the two side plates, wherein the lower ends of each side plate are respectively It is welded and fixedly connected with the upper end of the groove wall of the corresponding beam box, and the upper end of each side plate is welded and fixedly connected with the web plate of the corresponding side of the I-beam respectively. This means that the welding of four weld seams is required to complete the welding of a crane girder. The existing construction method is to weld the convenient one side weld seam earlier by hand, then the crane girder is turned over by the overturning device, and then Carry out the welding const...
