Bridge swivel construction structure

Abstract

The invention provides a bridge swivel construction structure, and belongs to the field of bridge construction. The bridge swivel construction structure comprises a lifting frame, a hoister and a steel rope, wherein the hoister is arranged on the lifting frame; an output shaft of the hoister is connected with a first gear and a second gear which have the identical diameters; a rotating shaft is arranged on the lifting frame; the steel rope is wound at the end part of the rotating shaft; a third gear and a fourth gear are arranged on the rotating shaft; the diameter of the third gear is greater than that of the fourth gear; the rotating shaft has a first working position and a second working position; when the rotating shaft is located at the first working position, the first gear is meshed with the fourth gear, and the second gear is separated from the third gear; and when the rotating shaft is located at the second working position, the second gear is meshed with the third gear, and the first gear is separated from the fourth gear. When the bridge swivel construction structure is applied to a swivel bridge construction process, an object can be quickly hoisted and transported, an output can be adjusted according to different cargo weights, and cargoes can be hoisted better and more quickly.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a bridge swivel construction structure. Background technique [0002] At present, the swivel bridge is one of the important bridge construction forms, and the construction of a bridge with a large span can be completed through the swivel bridge. [0003] During the construction process of the swivel bridge, there are many procedures, and various building materials and tools are required. In traditional construction, most of the building materials and tools need to be hauled by manpower. Nowadays, cranes and other equipment are used in the construction process of bridges, through which building materials can be quickly transported to the bridge deck. [0004] However, the structural design of the current hoisting equipment is not reasonable enough, and it cannot effectively hoist goods with different weights, so that the hoisting equipment is overloaded or the load is too small...
