Central cable surface steel box girder integral type bridge deck crane

Abstract

The invention relates to the technical field of bridge construction, in particular to a central cable surface steel box girder integral type bridge deck crane. The central cable surface steel box girder integral type bridge deck crane comprises a sliding rail, a supporting truss and hoisting equipment, wherein a sliding device which is slidably connected to the sliding rail is arranged at the lower end of the supporting truss, and a pushing oil cylinder used for pushing the supporting truss to move in the clockwise bridge direction is arranged between the sliding device and the sliding rail; and the crane further comprises a distribution device which is located between the sliding rail and the supporting truss and can rotate around a vertical shaft in the axial direction, the distributiondevice is supported on the lower end of the supporting truss to form a cushion beam structure the width of which is larger than the width of the supporting truss in the transverse direction of a bridge is formed at the lower end of the supporting truss when the distribution device rotates to the transverse direction of the bridge, and the distribution device is suspended on the lower end of the supporting truss and does not influence the moving of the supporting truss in the axial direction of the bridge. According to the integral type bridge deck crane, the structure is simple, operation is convenient to operate, the hoisting efficiency of a steel box girder is improved to a great extent, the problem that the central cable surface is prone to interference of the bridge deck crane transferis solved, the construction time is saved, and great popularization value is achieved.

Description

technical field [0001] The invention relates to the technical field of bridge building construction, in particular to a central cable surface steel box girder integral bridge deck crane. Background technique [0002] Deck cranes are the most commonly used temporary structures for steel box girder construction. Commonly used bridge deck cranes include integral and separated structures. For steel box girders with double cable planes, integral bridge deck cranes and separated As for the deck crane, for the central cable deck steel box girder structure, integral deck cranes and separate deck cranes can also be used, and the type of deck crane to be used depends on the design parameters of the bridge. If the steel box girder on the central cable plane is hoisted by a separate deck crane, it can effectively avoid the interference of the stay cables on the bridge deck crane during construction, but the bridge deck crane acts on the installed steel box during hoisting. The reaction...
