Abstract
The invention relates to a resilient base plate sensor. The resilient base plate sensor comprises an upper pressure-bearing cover board, a lower pressure-bearing cover board, a resilient supporting piece and a pressure measurement shrapnel; the upper pressure-bearing cover board is fixedly connected with the upper portion of the lower pressure-bearing cover board through the resilient supporting piece and keeps an initial deformation interval with the lower pressure-bearing cover board; the fixed end of the pressure measurement shrapnel is fixedly connected with the bottom side of the upper pressure-bearing cover board or the top side of the lower pressure-bearing cover board; the deformation end of the pressure measurement shrapnel is fixedly connected with the top side of the corresponding lower pressure-bearing cover board or the bottom side of the upper pressure-bearing cover board. When the upper pressure-bearing cover board downwards presses the lower pressure-bearing cover board, the deformation end of the pressure measurement shrapnel deforms towards one side relative to the fixed end, and the current pressure value is obtained through the deformation. The resilient base plate sensor overcomes the defects of a well know rubber pressure measurement base plate, and has the advantages of having certain elasticity, being high in testing precision, good in stability, free of any modification on tested objects and easy to install, and the like.

Embodiment
The feature of resilient sleeper-bearing sensor of the present invention, effect and the technical purpose that will reach are had and clearly and comprehensively understands, coordinate the drawings and specific embodiments mode to be described in further details below.
As Figure 1-Figure 2, the resilient sleeper-bearing sensor 1 that the present invention proposes comprises, upper pressure-bearing cover plate 2, lower pressure-bearing cover plate 3, elastic supporting member for supporting optical member 4, positive stop lug boss bolt 5 and cross dynamometry shell fragment 6.Wherein, the top that elastic supporting member for supporting optical member 4 is connected to lower pressure-bearing cover plate 3 is fixed in the underrun of upper pressure-bearing cover plate 2, and keeps initial deformation spacing, as 1 ~ 2mm with lower pressure-bearing cover plate 3.The stiff end of dynamometry shell fragment 4 is fixedly connected with the top side of the bottom side of upper pressure-bearing cover plate 2 or lower pressure-bearing cover plate 3, and deformed end is fixedly connected with the top side of corresponding lower pressure-bearing cover plate 3 or the bottom side of upper pressure-bearing cover plate 2.Thus when upper pressure-bearing cover plate 2 presses down described lower pressure-bearing cover plate 3, the deformed end of dynamometry shell fragment 4 is out of shape to side relative to stiff end, obtain current pressure values by this deflection.
