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 unbalanced weight of the rotating body will cause the legs or safety posts to block the rotating body during the rotation process, so the requirements for the support system and balance system are very high, especially With the large tonnage of the current bridge rotating body, the requirements for the load-bearing performance and balance performance of the rotating body system 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

Embodiment Construction

[0053] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0054] Such as figure 1 As shown, a magnetic suspension power-assisted swivel seat for bridge swivel construction includes an upper base a9 and a lower base a1 that are rotatably matched, and an electromagnetic power assist assembly is respectively provided on the upper base a9 and the lower base a1. The electromagnetic assisting assembly of the upper base a9 and the electromagnetic assisting assembly of the lower base a1 are vertically opposite and mutually exclusive.

[0055] Such as figure 1 , 2 As shown in and 3, the lower surface of the upper base a9 is provided with a rotating spherical cap a10, the lower base a1 is provided with an upwardly protruding cylindrical portion, and the upper end surface of the cylindrical portion is provided with the rotating spherical cap. The crown a10 is adapted to the spherical crown cavity a2, and the rotating ...

Abstract

The invention discloses a bridge swivel construction magnetic assistance swivel seat which comprises an upper seat body and a lower seat body which are in running fit. Electromagnetic assistance components are arranged on the upper seat body and the lower seat body. The electromagnetic assistance components of the upper seat body and the lower seat body are arranged oppositely and repel each other. The bridge swivel construction magnetic assistance swivel seat has the beneficial effects that the repulsive force between the electromagnetic assistance components 1 can bear part of pressure applied by the upper seat body to the lower seat body, so that the pressure on the actual contact faces of the two seat bodies is reduced, the friction force between the upper seat body and the lower seatbody can be reduced overall, the stability of a swivel system is improved, and the rotation operation difficulty is reduced.

Description

technical field [0001] The invention relates to a device used in a bridge swivel construction method, in particular to a magnetic suspension power-assisted swivel seat 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 hinges and balance systems. Among all kinds of hinges, steel ball hinges, steel plate hinges and combined hinges are currently used more. Among them, steel ball hinges have the advantages of larg...
