Intelligent bridge height adjusting shock absorption support

Abstract

The invention discloses an intelligent bridge height adjusting shock absorption support. The support is characterized in that the shock absorption support comprises a support upper steel plate, an upper pedestal, a lower pedestal and a support lower steel plate, all of which are sequentially arranged from top to bottom, a polyhedral boss is arranged in the center of the bottom of the upper pedestal, two sliding bearing platforms are symmetrically arranged in the center of the upper portion of the lower pedestal, the upper surface formed by combination of the two sliding bearing platforms is aconcave face matched with the lower surface of the boss, and each sliding bearing platform is provided with a magnetic device capable of driving the corresponding sliding bearing platform to move in the horizontal direction. The support has the beneficial effects that the support is reasonable in structural design and simple in structure, vibration of a bridge can be effectively reduced, the bridge is prevented from being damaged by external force, and the safety of the bridge is improved; and the height of the bridge can be adjusted through an electromagnet and a permanent magnet which are arranged inside, and the support is intelligent and convenient to use.

Description

technical field [0001] The invention relates to the technical field of bridge vibration reduction, in particular to a bridge height intelligent adjustment vibration reduction bearing. Background technique [0002] With the development of the transportation industry, people have higher and higher requirements for travel roads. In road construction, bridge construction is the top priority. Under the action of external vibration, the bridge will cause its own vibration, which often causes damage to the bridge structure. Over time, this damage will directly affect the safety and service life of the bridge, and seriously threaten people's lives and property safety. [0003] At present, vibration isolation and energy consumption vibration reduction technologies have gradually attracted the attention of countries all over the world and are widely used in building structures and bridge structures. Commonly used in existing bridge vibration reduction systems are rubber bearings and ...
