Embodiment Construction
[0026] The technical scheme of the present invention will be described in further detail below in conjunction with accompanying drawing and embodiment:
[0027] In this example, see the attached figure 1 , 3 As shown, the center diameter of the guide rail surface is 19.5m, the width of the guide rail surface is 190mm, the overall flatness of the guide rail surface is required to be 0.25mm, and the bearing capacity is greater than 550 tons. It consists of 20 sections of monorail parts 1 welded to form a whole. The design and manufacture are divided into six steps: monorail part 1 design, welding groove design, monorail part 1 manufacturing, guide rail installation, guide rail welding, and U-shaped weld 2 grinding, as follows:
[0028] Step 1. Monorail part 1 design
[0029] The material of monorail part 1 is high-strength steel 42CrMo, which has been quenched and tempered, and has good toughness and impact resistance. The cross-sectional size is 400mm×210mm, adopts circular ...
