Description
Известные динамометры дл измерени усилий в тросах с применением электрических датчиков сопротивлени позвол ют измер ть усили при условии разрезани троса, что не всегда удобно.The known dynamometers for measuring the force in the cables using electric resistance sensors make it possible to measure the force under the condition of cutting the cable, which is not always convenient.
Предлагаемый динамометр позвол ет измер ть усили нат жени троса без нарушени его целостности, что имеет большое значение при испытани х тросов дл подвесок к вертолету, при бурении нефт ных скважин, при испытании вис чих мостов и т. д.The proposed dynamometer makes it possible to measure the tension of the cable without compromising its integrity, which is of great importance when testing cables for suspensions to a helicopter, when drilling oil wells, when testing wind bridges, etc.
Сущность изобретени заключаетс в том, что динамометр выполнен в виде жесткой скобы, закрепленной на испытуемом тросе так, чтобы последний имел между точками креплени скобы некоторую слабину.The essence of the invention is that the dynamometer is made in the form of a rigid bracket attached to the test cable so that the latter has some slack between the points of attachment of the bracket.
На чертеже схематически изображен боковой вид преДьТагаемого динамометра .The drawing shows schematically a side view of a PreV TAG dynamometer.
Динамометр представл ет из себ металлическую скобу 1, на внутреннюю и наружную стороны которой наклеены тензометрические проволочные датчики 2.The dynamometer consists of a metal bracket 1, on the inner and outer sides of which are attached strain-gauge wire sensors 2.
Скоба / жестко закрепл етс на тросе 3, при этом трос должен иметь слабину между местами закреплени , тогда при нат жении троса усилие передаетс скобе, вместо выключенного из работы участка троса.The bracket / is rigidly fastened to the cable 3, the cable must have slack between the fastening points, then when the cable is tensioned, the force is transmitted to the bracket, instead of the cable section that is turned off from work.
Возникающие в скобе напр жени воспринимаютс тензометрическими датчиками и регистрируютс на осциллографе или другом принимающем устройстве.The stresses arising in the bracket are sensed by strain gauge sensors and recorded on an oscilloscope or other receiving device.
С целью исключени проскальзывани троса в местах зажима при приложении больщих усилий, зажимы могут быть выполненными с конусными вкладыщами 4.In order to avoid slipping of the cable at the clamping points under the application of great efforts, the clamps can be made with tapered inserts 4.
Предмет изобретени Subject invention
Динамометр дл измерени усилий в тросах с применением электрических датчиков сопротивлени , отличающийс тем, что, с целью измерени усилий нат жени тросов без нарушени их целосг№ 139131- 2 Dynamometer for measuring the force in the cables with the use of electrical resistance sensors, characterized in that, in order to measure the tension forces of the cables without disturbing their purpose, No. 139131-2
ности, он выполнен в виде жесткой скобы, закрепл емой на испытуемом тросе так, чтобы последний имел между точками креплени скобы петлю (слабину).However, it is made in the form of a rigid bracket attached to the test cable so that the latter has a loop (slack) between the points of attachment of the bracket.
