Trestle crane barge final assembly technique

Abstract

The invention relates to an assembly technique of a gantry crane on a barge. Firstly, a deck barge is fixedly provided with two vertical tower frames so as to lead the gantry crane to be arranged by spanning the deck barge; the gantry crane is supported by the two tower frames which are arranged on the barge; large components of the gantry crane are assembled in advance at the front edge of the dock of the factory; a main beam is synchronously hoisted on the two tower frames by two large floating cranes and is fixedly connected with the tower frames; a flexible leg is then hoisted and fixedly butted to the main beam; the main beam section of the flexible leg end and the middle section of the main beam are fixedly connected with each other by a flange and a bolt; positioning welding is then carried out in a box body and all welding seams are completed then; a rigid leg is then hoisted and fixedly butted to the main beam; the main beam section of the rigid leg end and the middle section of the main beam are fixedly connected with each other by the flange and the bolt, and the positioning welding is carried out in the box body; all welding seams are completed. The assembly of gantry crane above-water is realized and the problems of whole hoisting, shipping and landing of the gantry crane are effectively solved by the assembly technique of the gantry crane.

Description

technical field [0001] The invention relates to a gantry crane, in particular to an assembly technology of a gantry crane on a barge. Background technique [0002] Nowadays, the trend of large-scale development of ships is rapid, and the docks are also being built larger and larger, and the span and height of the supporting dock gantry cranes are also increasing. Due to the large size and weight of such large-scale gantry cranes, the traditional method is Manufactured in sections in the factory, transported to the dock of the shipyard, assembled into components in sections, and then assembled on-site in the dock one by one using the single-horned gantry or double gantry, and using the cable lifting method. Because the on-site assembly will use a lot of manpower, material resources and dock space, the time is too long, and the safety is poor, which seriously affects the operation of the shipyard and restricts the development of production. If it is assembled at the manufactu...

Problems solved by technology

[0003] The task of the present invention is to provide a gantry crane assembly technology on a barge, which solves the problem that the traditional on-site assembly can only be shipped in parts due to the limitation of the factory site, which consumes manpower, material resources and time, and its safety is poor, which affects the operation of the shipyard. question
