Lead rubber shock insulation support, intelligent support and support monitoring system

Abstract

The invention discloses a lead rubber shock insulation support, an intelligent support and a support monitoring system and belongs to the technical field of supports. The lead rubber shock insulation support comprises a top support plate, a bottom support plate, a lead rubber support body and a cushion plate. A pressure sensing unit is arranged between the top support plate and the cushion plate or between the bottom support plate and the cushion plate. The intelligent support comprises a data acquisition unit, a data output unit and the lead rubber shock insulation support. The support pressure measured by the pressure sensing unit is transmitted to the data output unit through the data acquisition unit. The support monitoring system comprises the data acquisition unit, the data output unit, a monitoring center and the lead rubber shock insulation support. By the adoption of the lead rubber shock insulation support, the stress condition of the support can be monitored in real time, the pressure sensing unit is convenient to replace, and the overall mechanical performance of the support is not affected; and 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 lead rubber 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 lead core rubber bearings in seismic isolation bearings have been widely used in actual bridge projects in many countries around the world due to their remarkable seismic isolation effect and relatively mature technology. Applications. 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. Bearing failure will lead to the overall collapse of the entire bridge, resulting in immeasurable serious consequences, so the long-term safety of the bearing is particularly important. For the vibration isolation bearings made of rubber materials, the rubber materi...

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 a major problem for the current bearings. A difficult problem in the technical field. Because the sensing unit is usually fixed to the support body or buried 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.
