Embodiment Construction
[0013] A curved surface support with a horizontal compensation force sensor, the structure includes a support top plate 1, a plane sliding pair 2, a curved surface sealing rotation sliding pair, a support bottom plate 6, and a support between the support top plate 1 and the support bottom plate 6 from top to bottom. The key of the horizontal force sensor 8 and the supporting monitoring circuit is that a horizontal prestress compensator is arranged between the horizontal force sensor 8 and the support top plate 1 .
[0014] The horizontal prestress compensator is a butterfly spring or magnetic damper or air spring structure.
[0015] The structure of the butterfly spring type horizontal prestress compensator includes: a positioning hole arranged on the support top plate 1, a mandrel 8-1 fixed to the horizontal load cell 8 through the positioning hole, and a flange plate at the end The butterfly spring 8-3 of 8-4, the head end of the butterfly spring 8-3 is arranged on the butte...

The invention provides a curved support with a horizontal comprehensive force transducer, to solve the technical problem of larger measurement error due to influences of poisson ratio and uneven deformation and temperature change of a supporting plate on the measurement of horizontal force in the prior art. According to the technical scheme adopted, the curved support structurally comprises a supporting top plate, a planar sliding pair, a curved sealing rotation sliding pair, a supporting bottom plate and a horizontal force transducer and a matched monitoring circuit, which are arranged sequentially from top to bottom, the horizontal force transducer and the mating monitoring circuit are arranged between the supporting top plate and the supporting bottom plate, and a horizontal prestress compensator is arranged between the horizontal force sensor and the supporting top plate. The curved support improves the accuracy and reality of the force measurement result.
Description
technical field [0001] The invention relates to a curved surface support with a horizontal force measuring sensor, which belongs to the field of bridge engineering construction, in particular to a curved surface support with a horizontal compensation force measuring sensor. Background technique [0002] Bridge support is an important part of the bridge engineering structure to automatically adjust the load to improve the stress state. Reasonably set sensors can accurately transmit the force and stress of the bridge superstructure components to the testing instrument to determine the safety status of the bridge support structure, and then make an accurate judgment on the safe bearing status of the bridge support , to ensure that the support can safely and reliably realize the adaptive change of stress. During the design and quality inspection of bridge supports, it is necessary to load enough force to simulate the impact of various external forces brought about by earthquake...
