Problems solved by technology
[0002] For the off-track type hollow beam structure, the trolley track (square steel or finished track) is directly welded to the girder rail bearing beam. During the welding process of the trolley track in the traditional girder track manufacturing process, excessive arching of the girder structure will occur. The side bend is out of tolerance and other problems, the work efficiency is poor, and it brings inconvenience to the later maintenance

Embodiment Construction
[0015] The implementation of the present invention will be illustrated by specific specific examples below, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.
[0016] A girder track manufacturing process, the girder 2 includes a main girder, a box body 8 is arranged in the main girder, and a partition is arranged in the box body 8, comprising the following steps:
[0017] (1) Position and fix the square steel track 1 on the upper panel of the girder 2, specifically including the following steps: s1, arrange the tire frame 3 and the jack 4 under the girder 2, release the stress of the girder 2 in a free state, and place the girder 2. The zero points of the flexible leg side 5 and the rigid leg side 6 are lifted to the same horizontal point; s2, check the flatness of the square steel track 1 and the rail bearing beam 7 fixed on the side of the girder 2; if the square steel tr...

The invention discloses a girder track manufacturing process. Girders comprise main beams. The girder track manufacturing process comprises the following steps that firstly, a square steel track is positioned and fixed to upper panels of the girders; secondly, the two girders are symmetrically arranged and fixed; and thirdly, according to the welding requirements, the square steel track is weldedto the upper panels of the girders. The girder track manufacturing process is designed mainly for a container rail-mounted gantry crane (a rail-mounted gantry crane), each girder structure is a deviated type hollow type, and a trolley track (the square steel or the finished track) is directly welded to bearing rail beams of the girders; and by means of the girder track manufacturing process, the problems that the camber and the side sway of the girder structures are out of tolerance which is caused in the welding process of the trolley track can be solved more effectively, the girder track manufacturing process can be widely applied to track manufacturing welding on various deviated type hollow girder structures, and the working efficiency is high.
Description
technical field [0001] The invention relates to the technical field of girder manufacture, in particular to a girder track manufacturing process. Background technique [0002] For the off-track type hollow beam structure, the trolley track (square steel or finished track) is directly welded to the girder rail bearing beam. During the welding process of the trolley track in the traditional girder track manufacturing process, there will be excessive arching of the girder structure, The side bend is out of tolerance and other problems, the work efficiency is poor, and it brings inconvenience to the later maintenance. Contents of the invention [0003] The object of the present invention is to address the deficiencies of the prior art, and now provide a girder track manufacturing process to solve the problems raised in the background art. [0004] In order to solve the above technical problems, the technical solution adopted in the present invention is: a manufacturing proces...
