Bridge girder erection machine with reinforcing and water shielding functions for bridge construction

Abstract

The invention relates to a bridge girder erection machine with reinforcing and water shielding functions for bridge construction. The bridge girder erection machine comprises a main frame, a main bracket, a front bracket, a back bracket, two girder lifting trolleys and several rolling wheels, a controller is arranged on the back bracket, and a fixing mechanism is arranged between the front bracketand the main bracket; a rain shielding mechanism is arranged above the end, away from the main bracket, of the main frame, the fixing mechanism comprises a connecting plate and two fixing assemblies,the fixing assemblies comprise first motors, lead screws and sleeves, and the rain shielding mechanism comprises a hinge block, a hinge ring, a cable rope, a transmission assembly and several hinge assemblies. According to the bridge girder erection machine with the reinforcing and water shielding functions for bridge construction, the main frame is reinforced through the fixing mechanism to avoid collapse accidents occurring in the bridge girder conveying process, the casualty rate is reduced, and the safety degree is higher; in addition, the rain shielding mechanism shields a bridge girdererection machine body from rain to avoid that the bridge girder erection machine is wet by rain and is rusted, maintenance cost is reduced, and the practicability is improved.

Description

technical field [0001] The invention relates to the field of bridge equipment, in particular to a bridge erecting machine with reinforcement and rainproof functions for bridge construction. Background technique [0002] The bridge erecting machine is the equipment that places the prefabricated girders on the prefabricated bridge piers. Bridge erecting machines fall into the category of cranes because their main function is to lift beams, transport them into position and then lower them down. [0003] Bridge erecting machines are very different from cranes in the general sense. The conditions required are harsh, and there is running on the beam, or longitudinal movement. There are several types of bridge erecting machines, such as highway bridges, conventional railway bridges, and passenger-only railway bridges. [0004] The existing bridge erecting machine is fixed with the erected bridge and bridge piers as supporting points, and the stability is not good enough. During ...

AI Technical Summary

Problems solved by technology

[0004] The existing bridge erecting machine is fixed with the erected bridge and bridge piers as supporting points, and the stability is not good enough. During the process of erecting the girders, it may collapse and cause casualties, which reduces the safety. Not only that, the existing Most of the bridge erecting machines are usually placed in the open air, and the bridge erecting machines are mostly made of metal structures, which are prone to rust in rainy weather, which increases maintenance costs and reduces practicability
