Door frame assembly for container crane, door frame and splicing method

Abstract

The invention provides a door frame assembly and door frame for a container crane and a splicing method. The door frame assembly for the container crane comprises two stand columns, an upper cross beam, a first standard formwork, a lower cross beam and a second standard formwork, wherein the two ends of the upper cross beam are connected with the first ends of the two stand columns respectively, and the first standard formwork is arranged between the stand columns and the upper cross beam and used for connecting the upper cross beam with the stand columns; and the two ends of the lower cross beam are connected with the second ends of the two stand columns, and the second standard formwork is arranged between the stand columns and the lower cross beam and used for connecting the lower crossbeam and the stand columns. The door frame assembly for the container crane is simple in structure and splicing method, the connection dimensions of all parts are accurate, installation is firm, theoccupied area of an installation site is small, the installation construction period is short, and the working efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a door frame assembly for a container crane, a door frame and a splicing method. Background technique [0002] With the development of marine engineering, cranes have been vigorously developed, and the door frame of shore-to-shore container cranes has also received more and more attention. Due to its large size, its manufacturing process has certain difficulties. [0003] In the manufacturing process of the existing door frame components, in order to ensure that the interface between the column and the upper and lower beams is aligned during final assembly and that the relevant opening dimensions meet the requirements of the drawings, pre-assembly is carried out after the columns and upper and lower beams are completed (also known as pre-assembly of the door frame on the sea and land sides). ), and add a positioning support at the connection port position, then disassemble the upr...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the present invention provides a door frame assembly for a container crane, which has a relatively simple structure and can solve the problems of the door frame assembly in the prior art, which occupy a wide range of assembly sites, use many mechanical equipment, and have a long construction period.
