Title:
INTEGRAL BRIDGE DECK CRANE FOR CENTRAL CABLE PLANE STEEL BOX GIRDER
Document Type and Number:
WIPO Patent Application WO/2019/196660
Kind Code:
A1
Abstract:
An integral bridge deck crane for a central cable plane steel box girder, comprising a slide rail (1), a support truss (2) and a lifting device; the lower end of the support truss (2) is provided with a sliding apparatus slidably connected to the slide rail (1); and a pushing oil cylinder (3) is provided between the sliding apparatus and the slide rail (1) for pushing the support truss (2) to move in a bridge longitudinal direction. Said integral bridge deck crane further comprises a distribution apparatus which is located between the slide rail (1) and the support truss (2) and is rotatable around a vertical axis; and the distribution apparatus supports, when in a bridge transverse direction after rotation, the lower end of the support truss (2) and forms a bearing girder structure with the width in the bridge transverse direction being greater than the width of the support truss (2), and hangs, when in the bridge longitudinal direction after rotation, on the lower end of the support truss (2) without affecting the movement of the support truss along the bridge longitudinal direction. The integral bridge deck crane has a simple structure, is easy to operate, greatly improves the lifting efficiency of the steel box girder, and solves the problem that the central cable plane easily interferes with the operation of the bridge deck crane.
