An anti-seismic experimental device for assembled bridge engineering

Abstract

The invention discloses an anti-seismic experimental device for assembled bridge engineering, which comprises a base, a movable seat and a first installation warehouse, a fixed warehouse is fixed at the middle position on the top of the base, and a second installation warehouse is installed on the outside of the fixed warehouse. Two toothed rings, and a movable seat is arranged inside the fixed warehouse, and a first annular chute is opened on both sides of the top of the base. This kind of anti-seismic experimental device for assembled bridge engineering is through the meshing connection between the first gear and the second gear ring and the first gear ring, and the meshing connection between the first gear ring and the second gear, so that the second When a motor drives the second rotating shaft to rotate, it can make the first rotating shaft continue to do planetary motion, and then drive the movable seat to shake in multiple directions, so that multi-directional vibration experiments can be carried out in a single time, and the bridge model on the placement plate can be further multiplied. Azimuth vibration, so that it is more in line with the actual use situation, and more comprehensive experiments can be carried out.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to an anti-seismic experimental device for assembled bridge engineering. Background technique [0002] With the continuous development of society, various public facilities are constantly improving. Bridges are one of many public facilities. Because the actual use environment of bridges is more complicated, they are divided into many types. Assembled bridges are more commonly used. In the design and manufacture process of assembled bridges, in order to ensure the safety of their use, it is generally necessary to carry out seismic experiments on their models, which requires the use of seismic experimental devices for assembled bridge engineering. The experimental device can basically meet the needs of people, but there are still some problems, the specific problems are as follows: [0003] 1. When the existing anti-seismic experimental device for assembled bridge engineer...
