Description
Изобретение касаетс приборов дл измерени деформаций струнным методом на больших базах с применением возбудител и измерител частоты колебаний струны.The invention relates to instruments for measuring strain by string method on large bases using an exciter and measuring the frequency of oscillation of the string.
Предложенный прибор в отличие от известных не ограничен базой, на которой устанавливаетс струна. Такое решение может упростить измерение деформаций в горных выработках, поперечных деформаций в туннел х и т. д. Дл этого длинна нат нута на испытуемом объекте струна несет на коротком измер емом участке закрепленное измерительное устройство, включаюшее возбудитель и измеритель частоты колебаний .The proposed device, in contrast to the known ones, is not limited to the base on which the string is placed. Such a solution can simplify the measurement of deformations in mine workings, transverse deformations in tunnels, etc. For this length is tight on the test object, the string carries a fixed measuring device in the short measurement area, which includes the exciter and the vibration frequency meter.
На чертеже изображен прибор в перспективе.The drawing shows the device in perspective.
При измерении микродеформаций горных выработок, туннелей или других сооружений на заданном участке нат гивают длинную струну 1. Примерно в середине струны / устанавливают на зажимах 2 измерительное устройство со смонтированным на нем электромагнитом 3. Под воздействием посылаемого из струнной станции 4 импульсного тока электромагнит 5 возбуждает колебани на ограниченном зажимами 2 участке струны 1. Затухающие колебани участка 5 струны принимаютс струнной станцией 4, пи показани м которой и определ ют микродеформации наблюдаемого сооружени .When measuring microdeformations of mine workings, tunnels or other structures, a long string 1 is pulled in a given area. Approximately in the middle of the string / a measuring device with an electromagnet 3 mounted on it is mounted on terminals 2. in the clamped 2 section of the string 1. The damped oscillations of the section 5 of the string are taken by the string station 4, the microstrains of the observed with which -equipment.
Предмет изобретени Subject invention
Прибор дл измерени деформаций струнным методом на больших базах с применением возбудител и измерител частоты колебаний струны , отличаюш,ийс тем, что, с целью измерени деформации крупногабаритных строений, применена длинна нат нута укрепл ема на испытуемом объекте струна, несуша на коротком измер емом участке струны неподвижно закрепленное измерительное устройство, включающее возбудитель и измеритель частоты колебаний.A device for measuring strain by a string method on large bases using an exciter and a measuring instrument for the frequency of oscillations of the string, is different in that, in order to measure the deformation of large structures, a long tension of the string being fixed on the test object was applied on the short measured portion of the string fixed measuring device, including a pathogen and an oscillation frequency meter.
