Integrated bridge crane

Abstract

The invention discloses an integrated bridge crane. The integrated bridge crane comprises a girder standard section, an A type guide beam extension section and a Y type high-shear-resistance extensionsection and is characterized in that the A type guide beam extension section is fixedly connected to the left end of the girder standard section, the Y type high-shear-resistance extension section isfixedly connected with the right end of the girder standard section, upper crossbeams are fixedly arranged on the girder standard section, the A type guide beam extension section and the Y type high-shear-resistance extension section, a bridge deck is arranged below the A type guide beam extension section, a hydraulic tail support leg is fixedly mounted at one end, away from the girder standard section, of the A type guide beam extension section, a front support leg is vertically fixedly connected to the bottom of the girder standard section, a reverse roller system is mounted between the topend of the front support leg and the girder standard section, and a front temporary support assembly is mounted at one end, away from the girder standard section, of the Y type high-shear-resistanceextension section. The integrated bridge crane is simple in structure, convenient in operation, and capable of greatly increasing work efficiency, safety and work reliability.

Description

technical field [0001] The invention belongs to the technical field of road and bridge construction, and in particular relates to an integrated bridge crane. Background technique [0002] At present, the common types of bridge erecting machines at home and abroad are one-span and two-span types. The so-called two-span bridge erecting machine means that the main girder of the bridge erecting machine is supported by the front, middle and rear legs, thus forming a two-span continuous beam structure. Form, during the beam erection operation, the beam transport vehicle will transport the beam to be erected to the rear span of the bridge erecting machine, and the lifting trolley on the main beam will lift the beam, and go to the hole to be erected in the front span to drop the beam into place. According to the operating characteristics of the two-span bridge erecting machine, the distance between the front and rear outriggers must be greater than the length of the two-hole box gir...

AI Technical Summary

Problems solved by technology

According to the operating characteristics of the two-span bridge erecting machine, the distance between the front and rear outriggers must be greater than the length of the two-hole box girder. The girders are erected in the immediate vicinity of the tunnel mouth, so their range of application is limited

However, the existing one-span bridge erecting machine solves the problem of small curve radius operations due to the small longitudinal size of the whole machine, but the hole-passing operations are relatively complicated. However, these two via methods have disadvantages such as cumbersome operations, low work efficiency, certain safety hazards, and poor adaptability to the working environment.
