Abstract

The invention belongs to the technical field of bridge engineering, and discloses a self-adapting bridge expansion and retraction device. The self-adapting bridge expansion and retraction device is used for solving the problems of many installation steps and poor rotation capability of the existing comb-tooth-shaped plate expansion and retraction device. The self-adapting bridge expansion and retraction device comprises fixed toothed plates arranged on a beam body and movable toothed plates arranged on the other beam body, wherein one end of each movable toothed plate extends to the beam body provided with the corresponding fixed toothed plate; the fixed toothed plates and the movable toothed plates are distributed in a mutually staggering way; each movable toothed plate is provided with a self-adapting variable-position ball seat used for fixing the movable toothed plate onto the beam body; each self-adapting variable-position ball seat comprises a variable-position ball seat; each variable-position ball seat is connected with an anchor bar used for installing the corresponding variable-position ball seat on the beam body; a rotating ball body is arranged in each variable-position ball seat; fastening screw bolts are arranged in each rotating ball body; the lower ends of the fastening screw bolts are hinged with a connecting rod; the lower end of each variable-position ball seat is provided with an installing cavity; a plurality of mutually overlaid elastic support plates are arranged in each installing cavity in a sleeving way; and each connecting rod passes through the corresponding variable-position ball seat to be hinged to the elastic support plates.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering, and in particular relates to an adaptive bridge telescopic device. Background technique [0002] With the rapid development of road transportation, the road traffic volume and vehicle load are also increasing, which puts forward higher requirements for the performance of road bridge expansion devices. Telescopic devices mainly include modular telescopic devices and comb-tooth plate telescopic devices. The vertical and horizontal rotation of the modular expansion device is better; the comb-tooth plate expansion device has the advantages of stable driving, small impact force, low noise and shallow installation depth. [0003] However, the multi-directional shifting seat and the anti-jumping system of the existing comb-shaped plate telescopic device are all connected to the movable tooth plate independently of each other, and the movable tooth plate is respectively realized by the multi-...
