Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] Look figure 1 , figure 1 The displacement structure of the expansion device of the present invention is shown along the vertical section of the bridge. As can be seen from the figure, the expansion device of the present invention is located at the expansion joint between the two sections of the bridge girder 13, and mainly includes fixed steel Comb plate 1 and movable steel comb plate 2 are provided with a multi-directional displacement box 3 capable of self-adaptive multi-directional displacement at the root of the movable steel comb plate 2. The movable steel comb plate 2 is anchored and connected with the multi-directional shift box 2. The fixed steel comb plate 1 is connected with the bridge main beam 13 through the fixed bolt 2 12, the movable steel comb plate 2 is connected with the bridge main beam 13 through the fixed bolt 1 6...

Abstract

The invention discloses a self-adaptive multidirectional dislocation method and a self-adaptive multidirectional dislocation device for a retractable device. According to the technical scheme, comb plate dislocation and elastic damping dislocation are combined; an elastic damping dislocation device is arranged at the root of a movable steel comb plate of a comb plate dislocation device, comprises at least one spring component or elastic component made of polyurethane polymer composites, and is in point contact with the movable steel comb plate. By the self-adaptive multidirectional dislocation method and the self-adaptive multidirectional dislocation device, the problems that steel comb-tooth-shaped retractable devices are poor in adaptability to dislocation, tires are punctured by bolts, driving safety is affected, service life is not ideal and the like in the prior art are solved; the self-adaptive multidirectional dislocation device is simple in structure and low in production cost.

Description

technical field [0001] The invention relates to an adaptive multi-directional displacement method and device of a bridge telescopic device, in particular to a self-adaptive multi-directional displacement method and device of a steel comb-shaped large telescopic bridge telescopic device, belonging to bridge structures Telescopic device technical field. Background technique [0002] With the rapid development of road transportation, the road traffic volume and vehicle load are also increasing, and higher requirements are put forward for the design of road bridges. One of the more important components in the design of road bridges is the bridge expansion joints. retractable device. In recent years, steel comb-tooth-type large-scale expansion bridge expansion devices with multi-directional displacement performance have been widely used in long-span suspension bridges, cable-stayed bridges and other bridges. In order to realize the vertical, lateral and torsional displacement o...
