Problems solved by technology
When the center of gravity of the swivel beam and the vertical axis of the ball joint are basically coincident through the counterweight, the swivel beam is in a state supported by a single ball joint, and the traction force required for the start of the swivel body is relatively small, but this scheme is likely to cause rotation during the rotation process. The unstable shaking of the body beam in the vertical plane; when there is a certain amount of eccentricity between the center of gravity of the swivel beam and the vertical axis of the spherical hinge through the counterweight, the swivel beam is in the joint support state of the spherical hinge and the legs, which increases the The stability of the body in the vertical plane during the rotation process, but this scheme is prone to the situation that the steel support feet and the glide path turntable are abnormally tight and unable to rotate normally during construction.

The invention discloses a bridge horizontal rotation construction dynamic balance weight system based on feedback control, comprising a rotating beam that is connected with a sensing unit and an actuating unit; the sensing unit monitors relevant information of horizontal inclination of the rotational axis of the rotating beam and transmits inclination information to a control unit; the control unit compares the inclination information and a preset threshold and transmits executive information to the actuating unit; the actuating unit executes a command of the control unit and adjusts, in realtime, the magnitude and position of a weight on the rotating beam. The bridge horizontal rotation construction dynamic balance weight system based on feedback control has the advantages of high visuallevel, high adjusting speed, good simplicity, monitoring timeliness, interference adaptiveness and the like; stability and safety of the whole process of bridge horizontal rotation construction are forcibly guaranteed.
Description
technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to a dynamic balance counterweight system for bridge translation construction based on feedback control. Background technique [0002] Bridge swivel construction refers to the construction method that the bridge structure is poured on the non-design axis, and the formed bridge structure is rotated to the design axis position by using the spherical joint, slideway and turntable structure with a small friction coefficient. Compared with the balanced cantilever construction method, the swivel construction can effectively utilize the terrain conditions around the route, and has the advantages of good construction conditions, safety and reliability, and obvious economic benefits. Solid construction has become the best solution to minimize the impact on existing lines. [0003] An ideal swivel system must meet two basic conditions: safe and stable and easy to rota...
