Spherical steel support, intelligent support and support monitoring system

Abstract

The invention discloses a spherical steel support, an intelligent support and a support monitoring system and belongs to the technical field of supports. The spherical steel support comprises a top support plate, a bottom support plate, a spherical steel plate and a cushion plate. The cushion plate and the top support plate or the bottom support plate are arranged in a laminated manner. 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 spherical steel support, and 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 spherical steel support. By the adoption of the spherical steel 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 spherical steel support, an intelligent support and a support monitoring system. Background technique [0002] Due to its large bearing capacity and relatively mature technology, spherical steel bearings have been widely used in actual bridge projects in many countries around the world. Spherical steel bearing is a commonly used bearing form in bridges. It is widely used. It is reliable in force transmission, flexible in rotation, and can better adapt to the needs of large rotation angles. The spherical steel bearing transmits force through the spherical surface. There is no radial contraction of force, and the rotation process of the support is realized through the sliding of the spherical PTFE plate. The rotational torque is small, and the rotational torque is only related to the spherical radius of the support and the friction coefficient of the PTFE plate. The rotation an...

Problems solved by technology

[0004] 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.
