Background technology
Rotatable type curved surface steel supports such as existing sphere, hyperboloid shaped steel bearing are compared with traditional pot rubber bearing, have that bearing capacity is big, power transmission is reliable, rotate flexibly, corner is big, long service life, be specially adapted to characteristics such as low temp area, therefore have more widely and use, in order to improve and to guarantee that circuit runs at a high speed, vertical, horizontal direction on bearing is provided with respectively carries out device for monitoring to external shock power at random, in time obtains data and analyzes.Device for measuring force comparatively commonly used at present only limits to unidirectional pressure dynamometry, and still immature three-dimensional monitoring device is that force-measuring module directly is set between upper bracket top cover and middle steel liner plate, multiple spot is provided with pressure-sensitive assembly on force-measuring module, external impact force is carried out the detection of whole synthesis, owing to exist the disadvantage of mutual interference effect between all directions external shock power, low, the comprehensive back of survey data precision classification analysis complexity; The volume of monitoring device is big simultaneously, the processing cost height; In case problems such as directionality, sensitivity appear in the one side of monitoring device, just whole device need be replaced, maintenance cost height, application life lack, and above-mentioned problem has brought great challenge for the development in bridge construction field.
Summary of the invention
In order to solve the deficiency that certainty of measurement is low, processing cost is high, application life is short that prior art causes, designed a kind of rotatable type curved surface steel support that has the three-dimensional strength measurement device, by in device, setting up level, the vertically raising of the method realization certainty of measurement of load cell separately.
The utility model for realizing the technical scheme that goal of the invention adopts is, a kind of rotatable type curved surface steel support that has the three-dimensional strength measurement device, include the upper bracket top cover in the structure, undersetting chassis and be positioned at above planar slide pair between the two successively, the rotation sliding pair structure of forming by middle steel liner plate, and be arranged on load cell between the upper member and supporting information delivery port, described load cell includes the horizontal load cell that is arranged between upper bracket top cover and the undersetting chassis, and being arranged on the liner plate seat of rotation sliding pair and the vertical load cell between the undersetting chassis, above mechanism forms level, the three-dimensional strength measurement device that sets up separately on the vertical direction.
Horizontal load cell is responsible for measuring the horizontal component of impact force, vertically load cell is responsible for measuring the vertical component of impact force, two components are carried out comprehensive analysis processing, just can obtain the precise information of impact force, because the upper bracket top cover that the dynamometer of horizontal direction is surveyed and the spacing on undersetting chassis have minimum rotation loss, force measuring method has than before improved precision.
The beneficial effects of the utility model are, the employing level, vertically set up the mode of load cell separately, the certainty of measurement height, and load cell is carried out the realization means that modular design is arranged owing to abandoned, the method that employing is set up separately makes that processing cost is low, technology is simple, load cell can be replaced separately, and maintenance cost reduces.
