Anti-seismic experiment device for assembled bridge engineering

Abstract

The invention discloses an anti-seismic experiment device for assembled bridge engineering. The device comprises a base, a movable seat and a first mounting bin, wherein a fixed bin is fixed to the middle of the top of the base, a second gear ring is mounted on the outer side of the fixed bin, the movable seat is arranged in the fixed bin, and first annular sliding grooves are formed in the two sides of the top of the base. According to the anti-seismic experiment device for the assembled bridge engineering, the first gear is in meshed connection with the second gear ring and a first gear ring; the first gear ring and a second gear are in meshed connection; a first motor drives a second rotating shaft to rotate; a first rotating shaft can continuously perform planetary motion along with the first rotating shaft, and then the movable seat is driven to shake in multiple directions, so that a multi-direction vibration experiment can be performed once, a bridge model on the placement platecan be driven to further vibrate in multiple directions, the actual use condition is better met, and a more comprehensive experiment can be performed.

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...
