Bridge crane diving platform structure and its installation process

Abstract

The invention relates to a bridge crane diving platform structure and a mounting process thereof. The bridge crane diving platform structure comprises a first assembly, a second assembly and a third assembly which are assembled in sequence from the front to the back. The mounting process of the first assembly comprises the step that when a left side door frame and a right side door frame are assembled, the first assembly is mounted to the right position. A mounting process of the third assembly comprises the steps that when a front girder is lifted to an eight-meter jig frame, a diving platform truss is located and mounted with the center line of a landside upper cross beam as the baseline; and the height of the third assembly is adjusted, and it is guaranteed that a cab is level with the third assembly. A mounting process of the second assembly comprises the steps that after the door frames, the front girder and a rear girder are assembled, the second assembly is preassembled; then the first assembly, the second assembly and the third assembly are bound with coir ropes; diving platform lower support bolts are loosened; the height of the first assembly is adjusted so that the first assembly can be aligned with the third assembly; and then the second assembly is connected to the first assembly and the third assembly properly. The bridge crane diving platform structure and the mounting process thereof have the beneficial effects that an improved diving platform is simple in structure and convenient to mount; fire work is effectively avoided; and the second assembly which is finally mounted is small, and large-size hoisting equipment such as vehicles is not needed to be used when bolts are screwed, so that equipment cost is saved.

Description

technical field [0001] The invention relates to the technical field of hoisting, in particular to a bridge crane diving platform structure and an installation process thereof. Background technique [0002] Bridge cranes are the main lifting machinery for loading and unloading containers from cargo ships, and are the heart of the terminal. With the continuous development of my country's crane manufacturing industry, bridge cranes made in my country have occupied nearly 80% of the global market share and entered more than 70 countries and regions. The production of bridge crane structures has been extensively contacted and absorbed foreign relevant codes, which often lead to discussions on the rationality of bridge crane structure design, manufacture and installation. Now it has adapted to the rapid development of science and technology and foreign crane manufacturing industries, and is gradually integrating with international standards. However, there are few discussions and...

AI Technical Summary

Problems solved by technology

[0005] The production and installation process is relatively complicated, the cycle is long, and the production cost is high. The quality of the diving platform after installation cannot be guaranteed, and it requires secondary fire, painting and high-altitude operations for workers.
