Friction pendulum shock insulation support, intelligent support and support monitoring system

Abstract

The invention discloses a friction pendulum shock insulation support, an intelligent support and a support monitoring system, and belongs to the support technical field. The friction pendulum shock insulation support includes a top support board, a bottom support board, a top hinged part, a bottom hinged part, and a base board. The base board and the top support board or the bottom support board are laminated, and a pressure sensing unit is arranged between the top support board and the base board or between the bottom support board and the base board. The intelligent support includes a data acquisition unit, a data output unit, and the friction pendulum shock insulation support. The data acquisition unit transmits the support pressure measured by the pressure sensing unit to the data output unit. The support monitoring system includes a data acquisition unit, a data output unit, a monitoring unit, and the friction pendulum shock insulation support. The friction pendulum shock insulation support can monitor the stress condition of the support in real time, so the replacement of the pressure sensing unit is facilitated, and the mechanical performance of the support is not influenced. The support monitoring system can monitor and reflect the health state of the support in real time.

Description

technical field [0001] The invention relates to the technical field of supports, in particular to a friction pendulum shock-isolation support, an intelligent support and a support monitoring system. Background technique [0002] At present, seismic isolation bearings are widely used in the field of bridges, and the friction pendulum isolation bearings in seismic isolation bearings have been used in actual bridges in many countries around the world due to their remarkable isolation effect, large load bearing, and relatively mature technology. It has been widely used in engineering. In the bridge structure, the support is the main force-transmitting component, and its stability and reliability directly affect the safety performance of the entire bridge. The failure of the bearing will lead to the overall collapse of the entire bridge, resulting in immeasurably serious consequences. At the same time, when the stressed members of the upper structure or lower structure of the br...

Problems solved by technology

[0003] In the prior art, the monitoring of the force of the isolation support mainly relies on the pressure sensing unit, and the data information after the pressure is measured by the sensing unit needs to be derived through the lead wire, so it is necessary to make microholes on the support for use Because the bearings of the bridge need to bear huge loads, even small pores will cause huge safety hazards; in addition, the replacement of the sensing unit is also the current support. A difficult problem in the technical field. Because the sensing unit is usually fixed to the support body or embedded inside the support, if the sensing unit is to be replaced, the entire support needs to be replaced, which is costly and complicated to operate.
