Bridge crane diving platform structure and mounting process thereof

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 lifting, in particular to a bridge crane diving platform structure and an installation process thereof. Background technique [0002] The bridge crane is the main hoisting machinery for loading and unloading containers from freighters and is the heart of the terminal. With the continuous development of my country's crane manufacturing industry, bridge cranes made in my country account for nearly 80% of the global market share and have entered more than 70 countries and regions. The manufacture of bridge cranes has extensive contact with relevant foreign standards, which often triggers discussions on the rationality of the design, manufacture and installation of bridge cranes. It has now adapted to the rapid development of science and technology and foreign crane manufacturing, and is gradually in line with international standards. However, there are few discussions and improvements in the fabrication and inst...

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.
