Abstract

The invention provides manual single-point synchronous traction equipment and method of a chain hoist, which are applicable to a bridge swivel construction traction process. Traction force of one section of a steel wire rope is swerved by a swerving effect of a fixed pulley and then is combined with the other section of the steel wire rope, so that two-point traction at the two ends of a common rotary table is converted into single-point traction; the aims that traction is synchronous, the two ends are commonly stressed and the size of the traction force is consistent are realized. The method equipment has a simple structure and is portable; the aim that the transportation is convenient can be realized under the condition that the construction condition is limited, the construction measure cost is greatly saved and the total engineering cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to a chain hoist manual single-point synchronous traction device and a construction method in bridge swivel construction. Background technique [0002] Bridge swivel construction refers to a construction method in which the bridge structure is formed at a non-design axis position and then put in place by swivel. Compared with the previous construction techniques such as cantilever assembly, cantilever pouring, and in-situ cast-in-place, swivel construction has the advantages of no interference with traffic, uninterrupted navigation, crossing deep ditches, rivers, and roads with frequent traffic, as well as rapid construction and high economic benefits. , it has been more and more widely used in bridge construction. Bridge swivel construction can be divided into vertical swivel method, horizontal swivel method and construction method combining vertical swivel...
