Description
Technical field
The present invention relates to steel support, belong to the bridge engineering construction field, particularly the hinge shaped steel bearing and the curved surface steel support of band level compensation load cell with load cell.
Background technology
Bridge pad is the vitals that the automatic adjusting load in the bridge engineering structure improves stress.Rationally the sensor that is provided with can send the form of stressed member behind the stressed and stress changes of bridge superstructure parts accurately to detecting instrument and make judgement accurately with the safe condition of the seat structure of judgement bridge and then to bridge pad safe bearing load situation, to guarantee the adaptive change of the realization stress that bearing can be safe and reliable.Bridge pad is when when design and quality examination, and the impact force that simulated earthquake, bump, vehicle overload, the wind that needs to load enough great dynamicses such as carries at the various external force of bringing is carried out rupture test, also needs the synchrodata monitoring simultaneously.
In order to improve and to guarantee that circuit runs at a high speed, vertical and be horizontally disposed with the sensor of monitoring external destructive power at random in bridge pad, in time to take data and to analyze accurately.
In the bridge pad structure of using at present, realize that there is very big problem in STRESS VARIATION monitoring accurately.Load cell and transmit exists the self adaptation gap of moving about between the external force contact surface, can not certainty factor thereby the bearing loading process China and foreign countries masterpiece that causes burst when adjusting in the self adaptation gap is used for that the distance " zero point " of deformation has, make accurately mensuration external force variation and deformation monitoring produce than mistake, to such an extent as to lose accurate Significance of monitoring.When external force test beginning, position initial point and corresponding force value must be set.Therefore, any micro-strain between curved surface bearing and the 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 also is Poisson ratio, is meant the lateral strain of material and the ratio of longitudinal strain.Promptly when bearing is subjected to produce vertical deformation under the vertical force effect, can produce corresponding lateral deformation, promptly expand, thereby it is stressed that horizontal load cell is contacted with stopping means, but the ergometry value of this moment is not the suffered horizontal loading of bearing, therefore, the dynamometry pattern of this general contact can be subjected to the very big influence of malformation.In like manner, the inhomogeneous deformation after seat board is installed, buckling deformation, variations in temperature and the material deformation that causes etc. all can produce interference to the dynamometry result of this general contact, influences measurement result.
Summary of the invention
Horizontal force measurement is subjected to poisson's ratio, a seat board inhomogeneous deformation and variations in temperature etc. to influence the technical problem that causes measure error bigger to the utility model in the prior art in order to solve, designed a kind of steel support, to solve the existing bigger problem of Dynamometric support measure error with load cell.
The utility model for realizing the technical scheme that goal of the invention adopts is, a kind of hinge shaped steel bearing with load cell, from top to bottom mainly comprise on the bearing successively in the described structure and putting, the bearing hinge, the bearing bottom, a friction pair and a seat board, wherein spool be connected by the bearing of cambered surface contact between pendulum and the bearing bottom on the bearing, form sliding friction by friction pair between the bearing bottom and the seat board, key is: be positioned with the horizontal load cell that end has horizontal prestressing force expansion loop on described the seat board, the head end of horizontal load cell withstands under the bearing and lays out, the compensation sensing force measuring machine of formation level.
A kind of curved surface steel support with the three-dimensional strength measurement sensor, structure comprises bearing top board, planar slide pair, vertical load cell, curved surface sealed rotational sliding pair, base-plate from top to bottom successively, improved key is: be positioned with the horizontal load cell that end has horizontal prestressing force expansion loop on the described bearing top board, the head end of horizontal load cell withstands on the base-plate.
Be equipped with horizontal load cell in existing hinge shaped steel bearing and the curved surface steel support.Horizontal load cell in the hinge shaped steel bearing is arranged between a seat board and the bearing bottom, and is positioned on the seat board; Horizontal load cell in the curved surface steel support is arranged between bearing top board and the base-plate, and is positioned on the bearing top board.In the middle of the practical application of horizontal load cell, because one of horizontal load cell end is fixing, has a free end, no matter be hinge shaped steel bearing or curved surface steel support, all can cause measure error thereby form the measurement discontinuous point owing to various variations inevitably produce the gap at the measuring junction of horizontal load cell.And the utility model is by setting up horizontal prestressing force expansion loop on horizontal load cell, guaranteed closely to contact between the base plate of horizontal load cell and steel support, avoids forming and measuring discontinuous point and cause measure error owing to producing the gap.Drive flanged plate compact disc spring by screwing pretension bolt, make dish spring aligning mandrel and horizontal load cell is produced certain precompression by mandrel, thereby eliminated the gap between the base plate of horizontal load cell and steel support, made its contact form become the bonding contact of inseparable prefastening.When the distortion of steel support generation Poisson or other distortion, horizontal load cell can be measured these power values of disturbing distortion to be produced simultaneously, in the data in later stage are handled, these interference values that measure can be eliminated by the simple mathematical computing, thereby eliminated the influence of perturbed force, improved dynamometry accuracy and authenticity the dynamometry result.
The beneficial effects of the utility model are: eliminated the influence to the dynamometry structure of machine deviation, assembly clearance; Eliminated the distortion of steel support Poisson, bearing top board or malformations such as the distortion of the bearing bottom, temperature deformation interference, improved dynamometry result's accuracy and authenticity measurement result; This apparatus structure is simple, and low cost of manufacture is convenient to maintenance and replacing, and is economical and practical.
