A Comb-tooth Bridge Expansion Device with Self-Adaptive Multidirectional Displacement

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...
