Embodiment Construction

[0028] Such as Figure 1 to Figure 2 Shown is a tire crane gantry segmented delivery and on-site docking process, the gantry structure includes a main beam and outriggers.

[0029] The segmental delivery process and docking process of the main girder are as follows:

[0030] The main girder needs to be cut into three sections. Confirm the section on the main beam, that is, the section line 1 of the main beam face plate and the section line 2 of the web plate of the main beam, and the section line 1 of the face plate of the main beam and the section line of the web plate of the main beam Stagger 200mm between lines 2;

[0031] Assemble the welded flange plate at section line 1 of the main beam face plate, and tighten the welded flange plate with process bolts to facilitate rapid and smooth splicing in the later stage;

[0032] Use a semi-automatic cutting machine to cut at the segment line. After cutting, remove the process bolts and keep them on the flange plate on one side ...

Abstract

The invention relates to a sectional transportation and on-site butt joint process for a portal frame of a tire crane. The sectional transportation and on-site butt joint process structurally comprises a main beam and support legs, and is characterized by comprising a tire crane portal frame sectional transportation process and a sectional tire crane portal frame on-site butt joint process. The main beam and the support legs are cut into sections at reasonable positions and then transported and ensured to reach a container yard of a user, cutting lines of panels and webs are staggered by 120-260 mm, and welding flange plates are assembled at the sectional lines of the panels, so that rapid and smooth alignment and splicing in the later period are facilitated; reasonable internal and external welding and up and down welding methods are adopted during on-site splicing, so that the butt joint quality is ensured, the problem of deformation easily generated in sectional butt joint is prevented, and the butt joint construction progress is promoted.

Description

technical field [0001] The invention relates to the field of tire crane gantry structures, in particular to a tire crane gantry segmented delivery and on-site docking process. Background technique [0002] The tire crane is a special equipment for flexible use in container yards. Its gantry structure is mainly composed of main beams, outriggers and saddle beams. The length of the beam is 9~12 meters. If it is transported over a long distance to the storage yard in the inland area, especially some unfamiliar storage yards abroad, there are many uncertain factors in the transportation of large pieces, and it is impossible to ensure that the spare parts can reach the user's storage yard smoothly. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a segmental delivery and on-site docking process of the tire crane gantry structure, so as to solve the problem that there are many uncertain factors in the transportation of ...
