Abstract

The invention provides a method for forming and assembling four faces of a bridge crane box type girder. A locating jig frame for adjusting camber by using a screw rod is arranged on the bottom surface of the girder, and corresponding push rods are arranged on the other three faces for locating and uses a worm mechanism so as to achieve back-and-forth telescoping. The method is suitable for multiple girder assembly. The running mode of a machine mechanism is simple, operation is convenient and reliable, assembly efficiency is high, and simultaneously torsion resistance and straightness of the girder and web plate verticality can be controlled well in the manufacturing process.

Description

technical field [0001] The invention relates to a method for manufacturing a crane mechanism, in particular to a four-sided forming and assembling method for a box-shaped main girder of a bridge crane. Background technique [0002] The current four-sided molding and assembly of the box-shaped girder of bridge cranes is mainly done manually, but because the manual operation cannot be precisely controlled, it has great constraints on the mass production of today's workshops, and it is not suitable for the existing production needs. In the process of main beam production and production, manual assembly mainly has the following disadvantages: [0003] 1. The production efficiency is very low; [0004] 2. It is difficult to grasp the assembly size; [0005] 3. The technical requirements of the main girder are difficult to control, such as the straightness, twist, and verticality of the main girder. Contents of the invention [0006] The purpose of the present invention is to...
