Box girder transport vehicle without negative moment reinforcement damage

Abstract

The invention provides a box girder transport vehicle without negative moment reinforcement damage. The box girder transport vehicle comprises a front vehicle system and a rear vehicle system, whereinthe front vehicle system comprises a front vehicle frame, the rear vehicle system comprises a rear vehicle frame, the front vehicle frame is hinged to the rear vehicle frame, the front vehicle frameis provided with a front bearing table, the front vehicle frame is provided with a front conveying system, the front vehicle frame is provided with a front notch, and the front conveying system is provided with a placement grabbing system; the rear vehicle frame is provided with a rear bearing table, the rear vehicle frame is provided with a rear conveying system, the rear vehicle frame is provided with a rear notch, the rear conveying system is provided with a recovery grabbing system, and the placement grabbing system and the recovery grabbing system are matched with cushion blocks correspondingly. The box girder transport vehicle has the advantages that the cushion blocks are additionally arranged on negative moment reinforcements, the cushion blocks protect the negative moment reinforcements, meanwhile, the transport vehicle walks on the cushion blocks, so that traveling of the transport vehicle is realized; the grabbing systems are matched with the transporting system to realize paving and recycling of the cushion blocks; the conveying system drives the grabbing systems to stretch and retract, so that paving of the cushion blocks during small-angle steering of the transport vehicle can be met.

Description

technical field [0001] The invention relates to bridge construction equipment, in particular to a box girder transport vehicle free from negative reinforcement damage. Background technique [0002] The box girder is a kind of middle beam in bridge engineering. It is hollow inside and has flanges on both sides of the upper part, similar to a box. It is the main structural component that connects the front and rear beams and forms the bridge deck. In the construction of existing viaducts, in order to ensure the adhesion between the bridge deck concrete poured later and the box girder, a large number of negative reinforcements are arranged on the top of the box girder. [0003] But at the same time, the box girder is large in size and heavy in weight. The box girder prefabricated in the prefabrication yard needs a transport vehicle to transport the box girder to the bridge erecting machine. The journey of the transport vehicle between the precast yard and the bridge erecting m...
