Problems solved by technology

[0002] During the hoisting and stiffening beam of the suspension bridge, due to the unbalanced force of the main cables on both sides of the main tower, the root of the main tower bears a large bending moment, which seriously affects the safety, stability and durability of the main tower
In the actual construction process, the cable saddle pre-deflection setting is often used to reduce the impact of the unbalanced main cable force, but this method is complicated to construct, requiring multiple cable saddle pushing steps, and more refined pre-deflection calculation
And once there is an error in the calculation, it is almost impossible to correct the deviation, resulting in unfavorable stress on the main tower

Abstract

The invention discloses a suspension bridge main cable-saddle saddle sliding state active control suction device and method, the device includes an electric control powerful arc-shaped suction cup covering the top surface of the saddle, and bolted wings on both sides arranged sequentially from top to bottom Plate, main cable hoop device, fastening device, the active regulating suction device is installed above the main cable strand and the saddle cable groove. The lower surface of the electric-controlled powerful arc-length suction cup covering the top surface of the saddle is empty (not in contact) with the uppermost main cable strands, and the device is powered on, and the electric-control strong arc-length suction cup generates an upward magnetic force to pull the main cable Suction up as needed to change the contact degree between the main cable and the saddle, so as to realize the active regulation of the sliding state of the main cable-saddle.

Description

technical field [0001] The invention relates to the field of bridge engineering construction, in particular to a suction device and method for actively regulating the sliding state of a main cable-saddle of a suspension bridge. Background technique [0002] During the hoisting and stiffening beam of the suspension bridge, due to the unbalanced force of the main cables on both sides of the main tower, the root of the main tower bears a large bending moment, which seriously affects the safety, stability and durability of the main tower. In the actual construction process, the pre-deflection setting of the cable saddle is often used to reduce the influence of the unbalanced main cable force. However, the construction of this method is complicated, requiring multiple steps of pushing the cable saddle, and more refined calculation of the pre-deflection. And once there is an error in the calculation, it is almost impossible to correct the deviation, resulting in unfavorable stress...
