Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] Due to the development of shipbuilding technology, the hull segments are getting bigger and bigger, the span and lifting capacity of shipbuilding gantry cranes are getting bigger and bigger, and the cross-sectional size and weight of the main girder of the crane are also getting bigger and bigger. The traditional technology can no longer meet the requirements of making the main girder of the shipbuilding gantry crane.

[0016] In order to solve the problems caused by the traditional process of manufacturing the main girder, a tire mold suitable for the manufacture of the main girder of the large-scale shipbuilding gantry crane is given in this embodiment, such as figure 1 , figure 2 As shown in , the tire mold for the main girder of the shipbuilding gantry crane includes two identical and opposite side tire molds 10, and the side tire ...

Abstract

The invention relates to a main beam manufacturing molding bed of shipbuilding gantry crane, which is characterized by comprising two same side molding beds which are arranged oppositely, and the side molding beds are connected by a bottom molding bed to form a rigid whole. Each side molding bed comprises a support, the support is provided with a staircase, and at least a layer of stay bars from up to down; each layer of stay bar is provided with a platform; and platforms on the two side molding beds are arranged oppositely. The tail ends of the stay bars are inclined surfaces, the inclination degree of the inclined surfaces is the same, and the tail ends of the stay bars exceed the support and the tail ends of the platforms. The bottom molding bed comprises a longitudinal beam, a horizontal beam, a vertical column and a dental plate; and the dental plate is fixed on the horizontal beam, and the vertical column is fixed below the horizontal beam. The mean beam manufacturing molding bed has the advantages of: (1) ensuring the overall linear camber of the main beam of the crane; (2) ensuring the assembly size of single sections of the crane; (3) simplifying the process, and saving the manufacturing cost; and (4) shortening the manufacturing cycle.

Description

technical field [0001] The invention relates to a tire mold for manufacturing the main girder of a shipbuilding gantry crane. Background technique [0002] Modern shipbuilding technology requires more and more cranes to be equipped. For example, the existing large shipbuilding gantry crane has a lifting capacity of 1600t, a span of 239m, a main beam section width of 10m, and a height of 16m. Many, resulting in high manufacturing difficulty. How to control manufacturing precision, deformation, and shorten the production cycle has become the key to manufacturing gantry cranes. [0003] The main girder of the shipbuilding gantry crane in the prior art is generally manufactured by the reverse fabrication method or the side fabrication method according to the size of the section. [0004] For the main girder segments with small cross-sectional size and light weight, they are manufactured by reverse fabrication. To make the roof frame, first hoist the roof, then install the dia...
