Wharf crane and construction method

Abstract

The invention aims at providing a novel structural wharf crane and a construction method thereof, and satisfies the needs of sectional transportation of the especially big bridge body of a modern long-span highway and a railway. The wharf crane of the invention comprises a plurality of groups of upright posts, a fixing suspension point and a crown block run system, and the fixing suspension point is composed of corresponding upright post bases, a main truss, a lifting truss, a windlass lifting system and pulley blocks. The wharf crane also comprises a cantilever, and the cantilever is composed of the front end of the main truss, the upright posts and a steel tube triangular support; the lower end is hinged with upright post bases; other upright posts are fixedly connected with the upright post bases. At least one upright post base near the cantilever forms a flexible connection with the main truss. The inner side of the steel tube triangular support is provided with a balance weight, and one balance weight is arranged on a position of the upright post. The main truss is provided with a longitudinal slope, and the slope can be set at 0.5 percent. The wharf crane has the construction method that the wharf crane steps over the highway, a riverbank and the cantilever are extended to a riverway; the wharf crane is spanned on a position of a pier used for constructing a new railway bridge, an included angle exists between a center line of the main truss of the wharf crane and the center line of the riverway, and the lifting truss is parallel to the center line of the highway.

Description

Technical field: [0001] The invention relates to the technical field of segmental transshipment of modern long-span highways and railway super-large bridges, in particular to a wharf crane and a wharf crane that realizes the beam body from the waterway to the shore and laterally moves into place without affecting the waterway and land transportation. build method. Background technique: [0002] Generally, prefabricated girders are transported by water, and the wharf is usually set up by trestle bridge method, which must occupy the river and affect navigation; and the height of trestle bridges is limited, which cannot meet the needs of transshipment of prefabricated beams across the road. There is no way to meet the transshipment requirements of long-span highways and railway super-large bridge body sections. Invention content: [0003] The object of the present invention is to provide a new type of wharf crane and its construction method, which can meet the segmental tran...
