Abstract

The invention discloses a combined type end beam connecting structure and relates to the technical field of cranes. The combined type end beam connecting structure comprises a main beam, a supportingleg A, a supporting leg B, a horizontal supporting part and an inclined supporting part. A fixed trunnion assembly A and a fixed trunnion assembly B are arranged on the top faces of the left end and the right end of the main beam separately. A fixed trunnion E is fixedly arranged on the outer side face of the supporting leg A, and a fixed trunnion F is fixedly arranged on the outer side face of the supporting leg B. The upper end of the supporting leg A is connected with the main beam through a trunnion assembly C, and the upper end of the supporting leg B is connected with the main beam through a trunnion assembly D. The combined type end beam connecting structure can meet different working condition requirements since a rigid-flexible leg structure can be freely combined.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a combined end beam connection structure of a gantry crane. Background technique [0002] With the continuous and rapid development of my country's economy, the demand for cranes is also increasing. As large-scale special equipment in the infrastructure and logistics and transportation industries, gantry cranes have become essential key equipment for many construction sites; The outriggers of traditional gantry cranes use box-shaped pillar components. This structure is safe and stable, but it is inconvenient to install and maintain. With the development of technology, current cranes generally use a rigid outrigger and a flexible outrigger to improve the stability of the crane. sex. Existing gantry lifting equipment is generally in the form of a fixed door leg structure, such as rigid leg-rigid leg, rigid leg-semi-flexible leg, rigid leg-flexible leg and other combinations. [0003...
