DEVICE AND METHOD OF FREELY INCREASE THE RESOLUTION FOR THE BRIDGE DISPLACEMENT SENSOR BY USING THE PULLEY SYSTEM

摘要

The present invention is characterized in that it is possible to increase the displacement of the end of the unfixed wire 125 by a desired multiple according to the relative displacement of the A pulley set 51 and the B pulley set 52 by combining one or more pulleys 124 The pulley device 50 and the pulley device set 121 designed using a method of manipulating and configuring the number and combination of the pulleys 124 of the pulley device 50 according to the intended magnification and purpose of use Displacement measuring device 120 for a pulley consisting of at least one sensor capable of measuring distance or displacement such as irradiation, sound wave emission, etc., the displacement measuring device 120 for the pulley, and a membrane (membrane) 114 that blocks disturbances. ), the bridge displacement measurement device 100, and the bridge displacement measurement device, characterized by an elastic structure consisting of an elastic structure 113 that can be installed according to various objects, and a modularized part that can be disassembled and assembled. (100) includes a method of measuring and managing the relative displacement of the upper structure 13 and the lower structure 16 of the bridge in three dimensions at any time or at all times. The bridge displacement measuring apparatus 100 of the present invention adopts the principle of a pulley to drastically lower the manufacturing cost (1/5 level compared to the existing one), so the displacement is constantly measured and the measured value is measured during the bridge repair work period. Based on the fact that it is possible to adjust the distance between the upper structure (13) and the lower structure (16) from time to time, the load imbalance problem between the piers (14) that occurs during work is solved, the risk of workers is reduced due to frequent displacement measurement in the high place, and the maintenance work time It will bring about reduction and cost reduction effect.
