Embodiment Construction
[0014] refer to figure 2 and image 3 , the straddle type monorail framework of the present invention is divided into 5 module parts altogether, is respectively wide side beam 3, narrow side beam 4, end beam 5, crossbeam 6, stable wheel 7, assembly welding process is as follows:
[0015] 1. The wide side beams, narrow side beams, end beams and cross beams are first assembled and welded into a large frame body: firstly fix the cross beams and end beams, then push the wide side beams and narrow side beams from the outside to the inside of the frame, and combine with the beams and The end beam is fixedly connected by plugging, and then the welding work of the above four parts is completed;
[0016] 2. Adjust and correct the large frame body that has been welded, and determine the process benchmarks of the X, Y, and Z axes of the workpiece;
[0017] 3. Assembling and welding the large frame body and the stabilizing wheels: first fix the large frame body, then assemble the two s...
