Embodiment Construction

[0018] In order to make the purpose, technical solutions and beneficial effects of the present invention more clear, the following will further describe the implementation of the present invention in detail in conjunction with the accompanying drawings.

[0019] Such as Figure 1 ~ Figure 2 As shown, the present invention provides a main girder structure of an electric single girder bridge crane. The cross section of the main girder is approximately "inverted trapezoid", which can improve the safety and stability of the entire main girder during lifting and moving operation. , including a symmetrically arranged end beam walking mechanism 1, and also includes a horizontally parallel bottom plate 2 and a top plate 3, the two ends of the top plate 3 are fixedly connected with symmetrical fixed rods 4, and the two ends of the bottom plate 2 respectively travel with the two end beams The mechanism 1 is fixedly connected, the two ends of the fixed rod 4 are fixedly connected with th...

Abstract

The invention belongs to the technical field of cranes, and provides a main beam structure of an electric single-beam bridge crane. The main beam structure comprises end beam walking mechanisms whichare arranged symmetrically, and further comprises a bottom plate and a top plate which are arranged horizontally in parallel. Fixing rods which are arranged symmetrically are fixedly connected to thetwo ends of the top plate, the two ends of the bottom plate are fixedly connected with the two end beam walking mechanisms respectively, the two ends of the fixing rods and the two end beam walking mechanisms are fixedly connected through inclined connecting rods, vertical straight web membranes are fixedly connected between the two ends of the fixing rods and the two corresponding ends of the bottom plate, multiple inclined web members which are arranged at intervals are fixedly connected between the fixing rods and the bottom plate, every two adjacent inclined web members are arranged symmetrically, and inclined supporting rods are fixedly connected between the connecting rods and the bottom plate. The main beam structure is small in self weight, the appearance is attractive, and the problem that an existing main beam structure of the electric single-beam bridge crane is large in self weight is solved.

Description

technical field [0001] The invention belongs to the technical field of cranes, and relates to a main girder structure of an electric single-girder bridge crane. Background technique [0002] Cranes are mainly special machines used for retrieving, transporting, unloading, etc. The development and use of cranes in the market are becoming more and more extensive, especially in construction, bridge construction, equipment assembly, handling, and maintenance in factories. It is widely used in the field. The existing electric single-girder bridge cranes are usually spliced ​​by steel plates into π-shaped beams, and then welded with I-beams to form a box-shaped structure. The main girder of this box-shaped structure has a relatively large dead weight, which increases the dead weight of the building structure , high cost. Contents of the invention [0003] The purpose of the present invention is to provide a main girder structure of an electric single-girder bridge crane, which ...
