Installation method of quay crane trapezoidal assembly

Abstract

The invention provides an installation method of a quay crane trapezoid assembly. The quay crane trapezoid assembly comprises a seaside upper cross beam and a trapezoid frame erected on the seaside upper cross beam. The method comprises the following steps that S1, two round-top and square-bottom parts are connected to the two ends of the upper surface of the seaside upper cross beam; S2, the actual assembly size of the seaside upper cross beam and the actual assembly size of the round-top square-bottom parts are measured through three-dimensional measurement equipment; S3, three-dimensional simulation equipment simulates the simulated assembly size of a trapezoidal frame according to the actual size; S4, splicing the trapezoidal frame according to the simulated splicing size; and S5, the bottom ends of supporting pipes of the spliced trapezoidal frame are installed on the two round-top square-bottom parts. According to the method, the pre-assembly process is omitted, the construction time and site are saved, and the installation progress of the quay crane trapezoidal assembly is greatly accelerated.

Description

technical field [0001] The invention relates to the technical field of port machinery manufacturing, in particular to a method for installing a trapezoidal component of a quay bridge. Background technique [0002] The quay crane is also known as the quayside container handling crane. The trapezoidal structure of the quayside bridge is an important part of the steel structure of the quayside bridge. The trapezoidal structure of the quayside bridge is erected on the upper beam structure on the sea side. This structure is also called a ladder frame. [0003] At present, the assembly of the ladder frame needs to be pre-assembled with the upper beam on the sea side before the final assembly. The assembly is carried out according to the actual assembly situation on site, and the card code and the steel liner at the lower opening of the support pipe are installed, so as to ensure that the ladder frame is assembled. The clearance and misalignment of the connection between the pipe a...

AI Technical Summary

Problems solved by technology

[0004] There are many disadvantages in the pre-assembly process: the number of transshipment and assembly sites for the upper beam on the sea side is increased; the assembly process of the upper beam on the sea side and the rear girder can only be carried out after the pre-assembly of the ladder frame is completed, which restricts the assembly progress of the rear girder; The side beams occupy the ladder frame assembly site, which reduces the utilization rate of the site
