Progress adjustment mechanism and its application method for direct braiding and erection of main cables of suspension bridges

Abstract

The invention relates to the field of production equipment of an inhaul cable of a suspension bridge and particularly provides a schedule adjusting mechanism for directly braiding and erecting a suspension bridge main cable and an application method thereof. The schedule adjusting mechanism for directly braiding and erecting the suspension bridge main cable comprises a cable thread (1) and a bracket (2), and is characterized by comprising a fixed wheel (3), a slide rail (4), a tackle (5), a movable wheel (6), a carrier roller (7), a steel wire rope (8), an end pulley wheel (9), a bracket (10), a fixed pulley wheel (11), a movable pulley wheel (12), a balancing weight (13), a first caution switch (41), a first shutdown switch (42), a second caution switch (43) and a second shutdown switch (44). An application method of the schedule adjusting mechanism for directly braiding and erecting the suspension bridge main cable comprises the following steps of synchronization of braiding and erecting, and asynchronization of the braiding and the erecting. The schedule adjusting mechanism has a simple structure, is convenient to use, is accurate to control, and has good synchronism and high erecting efficiency.

Description

technical field [0001] The invention relates to the field of production equipment for cables of suspension bridges, in particular to a progress adjustment mechanism for direct braiding and erection of main cables of suspension bridges and a method for using the same. Background technique [0002] At present, there are mainly two methods for the erection of the main cable of suspension bridges: the aerial cable method (abbreviated as AS) and the prefabricated cable strand method (referred to as PPWS). In the AS method, a turntable is used to transport a steel wire to the opposite bank at a time. In this way, the main cable of a suspension bridge needs to be turned back and forth tens of thousands of times, which often takes a year or even several years, and consumes a lot of time and manpower. At the same time, the AS method is very difficult to work and is greatly affected by the weather. The precision of the prepared cable strands is low, and the stress on each steel wire i...

Problems solved by technology

The direct braiding and hanging method is to make up for the deficiencies of the above two methods. The preparation of the main cable strands at the bridge construction site avoids the transportation difficulties of the PPWS method. The problem
