Embodiment
With reference to embodiment, the present invention will be described in detail.
The present invention relates to a kind of bridge overload early warning bearing, including upper steel plate 2, support body 4 and lower steel plate, the lower steel
Plate is concave surface steel basin 7, sets upper convex surface to rotate steel basin 5 between support body 4 and concave surface steel basin 7.Upper steel plate 2 and bearing sheet
Tetrafluoro slide plate 3 is provided between body 4, upper convex surface rotates and is provided with lower tetrafluoro slide plate 6 between steel basin 5 and concave surface steel basin 7,
Set to reduce frictional force.
The edge of upper steel plate 2 is provided with preformed hole 11, is connected by upper anchor bolt 1 with bridge floor girder；Concave surface steel basin 7 is logical
Anchor bolt 8 is crossed down to fix with bridge floor pier.
The bottom surface of upper steel plate 2 is alternatively concave groove, and the top surface shape of support body 4 adapts to therewith, forms bispherical knot up and down
Configuration formula.
The inductance bridge 10 for sensing the displacement of support body 4 is provided with support body 4, and is supplied for inductance bridge 10
The inductance bridge supply lines and data wire 9 of electricity and data transfer.Inductance bridge 10 is by 4 foil gauges 12 and 2 temperature-compensatings
One group of Wheatstone bridge of piece 13 and a collection of diode and measuring resistance composition, foil gauge 12 in inductance bridge 10 by
It can be extended after pressure.During implementation, bridge floor girder occurs as caused by pressure or other reasonses during change in displacement, can cause and bridge floor
The run-off the straight of upper steel plate 2 change of girder connection, and being arranged on the upper tetrafluoro slide plate 3 between upper steel plate 2 and support body 4 can subtract
Few horizontal frictional force so that produce horizontal displacement between upper steel plate 2 and support body 4, prevent the bias to vertical force with this
The influence of measurement, when receiving vertical force change, the lower tetrafluoro slide plate 6 that is arranged between convex surface steel basin 5 and concave surface steel basin 7
The frictional force of vertical rotating can be reduced, as described in Figure 2, upper convex surface, which rotates steel basin 5, to have a support force to support body 4, make
The inductance bridge 10 that must be arranged in support body 4（As shown in Figure 5）Foil gauge 12 elongation change resistance, cause output electricity
Pressure changes, and so as to produce detection data, and the data collected can be by using inductance bridge data line transfer to outside
Computer, carry out data processing and analyze the pressure and change in displacement situation of bridge.
The profile of support body 4 is integrally cylindrical, and outermost layer is bearing ring 14 in support body, is the cylinder with top plate
