Background technique
The important component of bridge pad connection bridge superstructure and substructure.Its loading characteristic is can only to bear
Pressure and certain shearing, and pulling force cannot be born.If bridge pad comes to nothing, this means that bridge pad and superstructure it
Between do not contact, change the stress of bridge, bridge beam body becomes unstable, under the action of car load, generates perpendicular
To vibration, bridge deck structure is destroyed, or the diseases such as destruction and cracking for causing pier cap.If the position of bridge pad have occurred compared with
When big sliding, it may appear that by biggish pressure under small area, support tilts support, and the shear resistance of support is significantly
Reduce, toppling etc. for bridge may be caused to seriously endanger.Therefore, it needs to carry out necessary bridge pad detection to bridge, examines
Survey the use state of support.
Two kinds can be generally divided into for the detection mode of support：One is traditional detection modes, including blade method, beam
Support checks the methods of mirror, bridge inspection vehicle, i.e., the use state of support is mainly judged in a manner of artificial judgment.Such as knife
Piece method proves that the gap between bridge and support is sufficiently wide if blade can be inserted between support and bridge, can be with
Determine that support is in the state come to nothing.Another detection mode is to adopt test result in conjunction with the detection mode of sensor detection
It is showed with the mode of data, so that detection is more accurate, it is more convenient.Such as in the installation process of support, using flat
The pressure of platen pressure sensor measured in advance support top surface is adjusted based on this in the position and height for calculating support.In bridge
In the later period monitoring of support, people start to realize digital supervision using sensor, have and carry out later period prison using hydrostatic sensor
It surveys, has the deformation displacement real time monitoring using fiber grating pair support, there are also using high-precision FBG displacement sensor etc..
Synthesis is both domestic and external the study found that realizing that the information-based Main way of bridge pad is rationally to tie support with sensor at present
It is combined.Just so far, sensor used in the collection for part of the force data is varied, wherein the most
A kind of common sensor is no more than pressure sensor.
But detection mode domestic at present does not install corresponding sensor detection device mostly, and sensor is examined
The disadvantages of survey mode is expensive there are sensor still uses without large scale investment at present.
Therefore, the new technical solution of one kind is needed in the prior art to solve the above problems.
Utility model content
The purpose of this utility model is to provide a kind of bridge pad detection devices, solve the prior art in detection bridge branch
The traditional detection mode error encountered when seat service condition is too big, precision is not high；And existing sensor detecting price
Valuableness is not easy to arrange, costly problem for being completed bridge.

Slider, displacement sensor, button cell, display screen, displacement patch；
The shell is fixedly connected with pedestal, and housing exterior walls top offers limiting slot, and lower part is built-in with spring support plate；
Upper end, slider include tip contact, compression unit, support portion, limit inside housings for the slider setting
Position block, wherein be fixedly connected at the top of the tip contact and support portion；The fixed company in described compression unit one end and support portion bottom
It connects, the other end is free end, and a pulley is additionally provided on the free end；The limited block is arranged on support portion outer wall；
The support portion bottom is also provided with link slot；
Lower end, one end pass through spring support plate inside housings for the column setting, and slider is arranged in the other end
In link slot, and spring bar is provided in the middle part of column；
The spring is set on column, and spring one end is connect with spring support plate, the spring other end and spring bar
Connection；
In the setting on the inner wall of the housing of institute's displacement sensors, displacement sensor electrically connects with display screen and button cell respectively
It connects；
The display screen and button cell are electrically connected, and the two is arranged on housing exterior walls；
Described displacement patch one end is fixedly connected with column, and the other end is contacted with displacement sensor.
Further, institute's displacement sensors are capacitive displacement transducer.
The utility model by adopting the above technical scheme can be brought the following benefits：
The utility model analyzes and determines out bridge by specific data by the variation of detection bridge pad relative altitude
The service condition of support has and uses simple and convenient, and tests accurate, cheap advantage, effectively overcomes existing
Bridge pad detection device there are the problem of.
