Description

Bridge turning anti-overturning device Technical Field The utility model relates to the technical field of bridge construction, in particular to a bridge swivel anti-overturning device. Background In the bridge construction process, when the bridge needs to cross the existing lines (such as railways, highways and the like) or other obstacles, a swivel construction technology is often adopted. The bridge swivel construction is to pour or assemble and mold the bridge structure at the position of the non-design axis, and then rotate the bridge structure to the position of the design axis through a swivel system. However, in the bridge turning process, there is a risk of overturning the bridge due to unbalance of the structure itself, construction errors, and external environmental factors (such as wind force, earthquake force, etc.). Once the bridge is overturned, huge economic loss and serious safety accidents are caused, and normal use of the bridge and safety of surrounding environments are affected. At present, the existing bridge swivel anti-overturning device has certain limitations in structural design and function realization. Some devices have complex structures and difficult installation and maintenance, and some devices have insufficient unbalanced and inclined monitoring and correcting capabilities and cannot effectively prevent the bridge from overturning in time. Therefore, a device which has a simple and reliable structure and can effectively prevent overturning in the bridge swivel process is urgently needed. Disclosure of utility model The utility model aims to provide a bridge swivel anti-overturning device which is stable and reliable in structure, strong in self-adaptive adjustment capability, firm in connection and convenient to install and maintain, can monitor in real time and correct an unbalanced state in a bridge swivel process in time, and effectively reduces bridge overturning risks. In order to achieve the above purpose, the utility model provides a bridge swivel anti-overturning device, which comprises a first turntable and a second turntable, wherein the first turntable and the second turntable are coaxially arranged, the first turntable and the second turntable are connected through a connecting mechanism, the connecting mechanism comprises a supporting component and a connecting component, and the supporting component is fixedly connected with the connecting component. Preferably, the connecting assembly comprises a sliding rail, a first sliding block, a connecting unit and a correcting unit, wherein the first sliding block is arranged in the sliding rail and is in sliding connection with the sliding rail, the correcting unit is arranged at the bottom of the first sliding block, the connecting unit is respectively connected with the sliding rail and the first sliding block, and the sliding rail is fixedly connected with the second turntable. Preferably, the quantity of correcting the unit is four, and the structure is the same, corrects the unit and includes ball, connecting plate, pneumatic cylinder, telescopic link, pressure sensor and spring, is equipped with the draw-in groove on the connecting plate, and in first draw-in groove was arranged in to ball part, ball below was fixed to be equipped with pressure sensor, and the bottom of connecting plate is connected with two telescopic links and a pneumatic cylinder, and the lateral wall of pneumatic cylinder is connected with two backup pads, and the other end and the backup pad fixed connection of telescopic link, telescopic link overcoat were equipped with the spring, the one end and the connecting plate fixed connection of spring, its other end and backup pad fixed connection.
