Problems solved by technology

These force-measuring methods must be calibrated through relevant tests before use, and some force-measuring support devices with too large tonnage are often unable to perform full-scale calibration of the data due to the limitation of the measurement range of the test equipment.
And because the sensor is a precision part, it is inevitable that factors such as bumps and vibrations will interfere with the force-measuring element during transportation and installation, thereby affecting the calibrated structure
In addition, pressure sensors generally have a low service life, and the service life of maintaining a certain accuracy cannot be reliably guaranteed. When the sensor needs to be replaced, most of the existing force-measuring support devices cannot be guaranteed to have replaceable functions, and some devices have replaceable functions. It is also unable to provide the function of calibrating the force measurement data on site

Abstract

The invention belongs to a force measuring device, and particularly relates to a dual-mode multi-channel force measuring device and application thereof. The device comprises a basin-type cavity, a rubber elastic body which is arranged in an inner cavity of the basin-type cavity and of which the outer edge is attached to the side wall of the inner cavity of the basin-type cavity, and a lining platewhich is attached to and covers the upper portion of the rubber elastic body; and a first hole channel is formed in the side wall, the bottom or the lining plate of the basin-type cavity, two ends ofthe first hole channel are respectively opened outside and on the outer surface of the rubber elastic body in the basin-type cavity, a pressure sensor is assembled in the first hole channel, a forcemeasuring end of the pressure sensor is attached to the surface of the rubber elastic body, a second hole channel is formed in the side wall of the basin-type cavity or the lining plate, and the two ends of the second hole channel are opened outside and on the outer surface of the rubber elastic body in the basin-type cavity respectively. The invention effectively solves the problems that in the prior art, sensor replacement, force measurement data calibration and the like cannot be conducted, and the device has the advantages that: sensor replacement and force measurement data calibration arefacilitated, and the force measurement result is accurate.

Description

technical field [0001] The invention belongs to a force-measuring device, in particular to a dual-mode multi-channel force-measuring device and an application thereof. Background technique [0002] Due to the lack of effective testing methods in the current road and railway bridge and building design codes, some loads and their distribution are calculated based on certain assumptions, and there are certain errors between the calculation results and the actual situation. If the error is too large, it may lead to improper use of the structure. Excessive safety or safety factor will lead to waste, so the actual measurement of structural load is the premise of safety and economy. Especially in recent years, bridges and building structure collapse accidents have occurred from time to time, which have caused huge losses to people's lives and property, and caused adverse social impacts on the society. The reason is that the structural load and its distribution have changed and accu...
