Abstract

The invention relates to the technical field of highway bridges, and discloses a telescopic device of a highway bridge. The telescopic device comprises a telescopic mechanism and two vertically arranged fixed plates. The telescopic mechanism is located between the two fixed plates, a plurality of metal sheets are arranged on the outer sides of the fixed plates at equal intervals, and the metal sheets are arranged upwards obliquely. The telescopic mechanism comprises a plurality of rubber belts and a plurality of vertical rods, the rubber belts are perpendicular to the fixed plates, the rubberbelts are arranged in parallel and connected through the vertical rods, extending plates are hinged to the upper ends of the two fixed plates, the extending plates are overlapped and are in sliding connection, the lower ends of the two fixed plates are horizontally connected with supporting plates, and a clearance is arranged between the two supporting plates. The vertical rods are divided into aplurality of branch rods, and the branch rods are detachably connected. According to the telescopic device, the rubber belts are protected, and the rubber belts can be replaced conveniently.

Description

technical field [0001] The invention relates to the technical field of highway bridges, in particular to a telescopic device for highway bridges. Background technique [0002] With the rapid development of my country's economic construction, high-grade highways represented by expressways have sprung up, and the traffic volume of highways has increased sharply. The speed of vehicles driving on the highways and the axle load of vehicles are increasing. The requirements are getting higher and higher, so in the past bridge design and construction, problems related to expansion devices that were not paid enough attention have become more and more prominent, forcing bridge design, construction, maintenance and management departments to pay full attention to this. The road bridge expansion device is mainly installed at the expansion joint between the two parts of the bridge beam body. It directly bears the repeated impact of the wheel load in the bridge structure, and is exposed to ...
