Embodiment Construction

[0062] The invention relates to an intelligent bridge expansion joint device, which belongs to the field of bridge structures and is suitable for identification of the expansion joints of the bridge structure and the load of vehicles traveling on the upper part of the bridge. For the convenience of those skilled in the art to understand accurately, the present invention will be further described in detail below in conjunction with the accompanying drawings, and the content mentioned in the embodiments does not limit the present invention.

[0063] An intelligent bridge expansion joint device, the device includes a mobile deck part, a plane truss part and a support part (such as figure 1 shown);

[0064] Move the board part (such as figure 1 , 2 , 3, 4, 5, 6, and 7) are arranged in parallel by several rows of moving slats, wherein the moving slats are composed of moving plates A 1 and moving plates B 2 alternately arranged from left to right, and the length of the moving slat...

Abstract

The invention provides an intelligent bridge expansion joint device and application thereof. The device comprises a movable plate surface part, a plane truss part and a supporting part; the plane truss part is composed of fixed hinges A, truss rods, movable hinges and fixed hinges B; when the relative displacement of the two ends of an expansion joint occurs, the height change of a truss is causedby the deformation of the plane truss; through the height complementation of lifting and falling of a support plate in the supporting part, the flatness of the movable plate surface part is ensured.Stress gauges are embedded in movable plates A and movable plates B, the stress generated by all axles is tested when a vehicle passes, and the passing time of the axles is accurately recorded. Goniometers are fixed on the movable hinges, and the included angles of the truss rods are recorded in real time. The weight of all the axles and the total weight of the vehicle are solved according to thestress values corresponding to all the axles; the speed of the vehicle is accurately solved according to test time data and in combination with goniometer data and truss rod length. The device has theadvantages of modular production, convenient installation and maintenance, simple use and the like, and the market prospects are very broad.

Description

technical field [0001] The invention relates to an intelligent bridge expansion joint device and its application, belonging to the field of bridge structures. Background technique [0002] As we all know, under the influence of factors such as temperature changes, concrete shrinkage, creep, and loads, the length of the bridge girder body will change, and the beam ends will be displaced. In order to maintain smooth driving, it is necessary to install bridge expansion devices. Bridge expansion joints are structural joints set between girder ends, between girder ends and abutments, or at the hinged position of the bridge in order to adapt to the deformation of the bridge structure, so that the bridge can withstand factors such as temperature changes, concrete shrinkage, creep, and loads. It can freely expand and contract under the influence. Bridge expansion joints are part of the bridge structure. If the design is improper, the installation quality is poor, and the maintenanc...
