Description
Technical field
The present invention relates to a kind of pot rubber bearing with horizontal load cell, belong to bridge engineering construction field, particularly a kind of benzvalene form supporting with level compensating load cell.
Background technology
Bridge supporting is the vitals that the automatic adjusting load in bridge engineering structure improves stress.The sensor rationally arranging can send the form of stressed member after the stressed and stress changes of bridge superstructure parts accurately to detecting instrument and make judgement accurately with the safe condition of the braced structures of judgement bridge and then to bridge supporting safe bearing load situation, with the adaptive change that realizes stress that guarantees that supporting can be safe and reliable.When bridge is bearing in when design and quality examination, the impact force that simulated earthquake, shock, vehicle overload, the wind that need to load enough great dynamicses such as carries at the various external force of bringing is carried out rupture test, also needs synchrodata monitoring simultaneously.
In order to improve and to guarantee circuit operation at a high speed, the vertical sensor with being horizontally disposed with the external destructive power of random monitoring in bridge supporting, to take in time data and to analyze accurately.
In the bridge supporting construction of application at present, realize STRESS VARIATION monitoring accurately and have very large problem.Load cell and transmitting exists the self adaptation gap of moving about between external force contact surface, can not certainty factor thereby the supporting loading process China and foreign countries masterpiece that causes while adjustment in self adaptation gap burst has for the distance " zero point " of deformation, Accurate Determining external force is changed and deformation monitoring generation error greatly, to such an extent as to lose the meaning of accurate monitoring.While beginning in the time that external force is tested, must setting position initial point and corresponding force value.Therefore, any micro-strain between support body and sensor all can cause the distortion of sensor, thereby makes the measured value distortion of sensor and cause the error of ergometry value.Poisson's ratio, is also Poisson ratio, refers to the lateral strain of material and the ratio of longitudinal strain.When bearing while producing vertical deformation under vertical force effect, can produce corresponding lateral deformation, expand, thereby make horizontal load cell and stopping means contact, but ergometry value is now not the suffered horizontal loading of supporting, therefore, the dynamometry pattern of this general contact can be subject to the very large impact of malformation.In like manner, the inhomogeneous deformation, buckling deformation, variations in temperature after base plate is installed and the material deformation that causes etc. all can produce the dynamometry result of this general contact to be disturbed, and affect measurement result.
Summary of the invention
The present invention solves horizontal force measurement in prior art to be subject to poisson's ratio, base plate inhomogeneous deformation and variations in temperature etc. to affect the technical problem that causes measure error larger, design a kind of benzvalene form supporting with level compensating load cell, to solve the larger problem of existing dynamometry supporting measure error.
The present invention is that the technical scheme that realizes goal of the invention employing is, a kind of benzvalene form supporting with level compensating load cell, structure comprises benzvalene form bearing plate, is arranged on pressure-bearing rubber tile, the supporting plate in bearing plate and is arranged on supporting plate middle steel liner plate between pressure-bearing rubber tile and supporting slide assemblies, also comprise the horizontal load cell that is arranged between supporting plate and middle steel liner plate and supporting observation circuit, improved key is: between described horizontal load cell and supporting plate, be provided with horizontal prestressing force expansion loop; Described horizontal prestressing force expansion loop is the horizontal prestressing force expansion loop of disc spring type, the structure of the horizontal prestressing force expansion loop of described disc spring type comprises: be arranged on locating hole on supporting plate, butterfly spring through locating hole and the fixing mandrel of horizontal load cell, end with flanged plate, the head end of butterfly spring is arranged on the butterfly spring abutment on mandrel, the flanged plate of end is spacing on supporting plate by pretension bolt.
Key of the present invention is: on horizontal load cell, set up horizontal prestressing force expansion loop, guaranteed close contact between horizontal load cell and support body, avoided causing measure error owing to producing gap formation measurement discontinuous point.Drive flanged plate compact disc spring by screwing pretension bolt, make dish spring aim at mandrel and by mandrel, horizontal load cell be produced to certain precompression, thereby eliminate the gap between horizontal load cell and support body, made its contact form become the bonding contact of inseparable prefastening.In the time of the distortion of supporting plate generation Poisson or other distortion, horizontal load cell can be measured these power values of disturbing distortion to produce simultaneously, at the Data processing in later stage, these interference values that measure can be eliminated by simple mathematical operation, thereby eliminate the impact of perturbed force on dynamometry result, improved dynamometry accuracy and authenticity.
The invention has the beneficial effects as follows: eliminated machine deviation, the impact of assembly clearance on force measuring structure; Eliminate the interference of malformation to measurement result such as the distortion of supporting Poisson, base plate distortion, temperature deformation, improved accuracy and the authenticity of dynamometry result; This apparatus structure is simple, and low cost of manufacture is convenient to maintenance and changes, economical and practical.
