Problems solved by technology

In the actual construction process, because the weight of the rotating body cannot be accurately calculated or there are construction errors, the weight of the rotating body is unbalanced, which may cause the rotating body to tilt, affect the construction or even fail to rotate. The requirements for load-bearing performance and balance performance are getting higher and higher, and it is required to reduce the rotational resistance as much as possible, but the existing technology cannot meet the requirements in this respect

Abstract

The invention discloses a lifting rotation assembly for bridge swivel construction. The lifting rotation assembly for the bridge swivel construction comprises a balancing lifting seat; a swivel seat is arranged on the balancing lifting seat; the balancing lifting seat comprises a lifting base; a jacking assembly is arranged on the lifting base; the jacking assembly comprises a central jacking piece; multiple groups of stabilizing jacking pieces are uniformly distributed around the central jacking piece; the swivel seat comprises an upper seat body and a lower seat body which are in normal running fit with each other; an electromagnetic power assisting assembly is arranged between the upper seat body and the lower seat body; and the lower seat body lies on the central jacking piece and allstabilizing jacking pieces. The lifting rotation assembly for the bridge swivel construction has the advantageous effects that the balance of a bridge swivel is convenient to maintain by adjusting thejacking forces of the multiple stabilizing jacking pieces on the balancing lifting seat; and meanwhile, by using the electromagnetic power assisting assembly, a rolling supporting body and a roller deflection prevention mechanism, the friction force between an upper swivel seat and a lower swivel seat is reduced; and the lifting rotation assembly for the bridge swivel construction is conducive toimproving the balance and reliability of a swivel system and enhancing the convenience of the swivel construction.

Description

technical field [0001] The invention relates to a device for a bridge swivel construction method, in particular to a lifting swivel component for bridge swivel construction. Background technique [0002] The bridge swivel construction method refers to a construction method in which the bridge is cast or assembled at a position deviated from the design, and then the bridge is rotated into place by means of power. This method can overcome terrain restrictions, the construction does not affect the traffic, it is convenient for prefabrication, and the construction is rapid, so it is more and more widely used. For bridges constructed with horizontal rotation, the key to the swivel construction method is the horizontal swivel system of the bridge, which includes lifting devices, swivel seats and balance systems. The lifting device is used in conjunction with the swivel seat to lift the bridge swivel body. When the bridge swivel body rotates to the predetermined position, the pist...
