Description

Действие устройства, согласно изобретению, основано на измерении усилий сжати  или раст жени  в выт нутых стержн х при помощи жестко св занной с испытуемым стержнем трубки, деформацию изтиба (вспучивание) стенок которой .замер ют закрепл емым на трубке тензометром. Схема устройства показана на чертеже.The operation of the device according to the invention is based on measuring compressive or tensile forces in the elongated rods using a tube rigidly connected to the test rod, and the deformation of the wall (swelling) of the walls of which is measured with a strain gauge fixed to the pipe. Diagram of the device shown in the drawing.

Прибор состоит из включаемых в Состав испытуемого стержн  штанг / и 2, своими утолщенными концами соединенных встык при помощи трубки 3, снабженной в нижней части внутренней нарезкой и кольцевым выступом; в верхней части трубка 3 снабжена нарезной муфтой 4.The device consists of rods / and 2 included in the composition of the test rod, their butt-end with their thickened ends connected by means of a tube 3, provided at the bottom with internal cutting and an annular protrusion; in the upper part of the tube 3 is equipped with a threaded sleeve 4.

Когда требуетс  определить уси .лие сжати  или раст жени  в выт нутом стержне, на трубке 3 укрепл ют тензометр, муфту 4 наверты-вают на трубку до плотно1го ooinpnкосновени  с заплечиком 5 на верхнем конце щтанги 2; затем трубку 3 поднимают выше, ввертыва  ее в муфту 4 и одновременно освобожда  нижний выступ штанги 2 от нажима заплечика 6.When it is required to determine the force of compression or stretching in the drawn rod, a strain gauge is fastened on the tube 3, the coupling 4 is screwed onto the tube to the tight ooinpn with the shoulder 5 at the upper end of the rod 2; then the tube 3 is raised higher, screwing it into the sleeve 4 and at the same time releasing the lower lip of the rod 2 from pressing the shoulder 6.

В стенках трубки 3 нарастает усилие изгиба (вспучивани ) от О до фактического в данный момент предела, фиксируемого тензометром In the walls of the tube 3, the bending force (swelling) increases from 0 to the actual actual limit fixed by the strain gauge.

Прибор может примен тьс  дл  проверки усилий нат жени  в судовых вантах, различных тросах, дл  определени  силы вспучивани  грунта при промерзании почвы и т. п.The device can be used to check the tension in the ship's cables, various cables, to determine the swelling force of the soil during soil freezing, etc.

Предмет изобретени  Устройство дл  определени  усилий в раст нутых или сжатых стержн х посредством измерени  деформаций тензометром, -отличающеес  тем, что на стержень /-2, разделенный поперечным разрезом на две части, надета трубка 3, котора  одним концом навинчена при помощи нарезки на одну из частей стержн , имеет внутренний выступ, могущий упиратьс  в выступ на конце второй части стержн , и снабжена Навинчивающейс  на свободный конец муфтой 4 с внутренним выступом, могущим упиратьс  во второй выступ стержн , с целью передачи усили , действующего в стержне, на трубку 3 и измерени  при этом ее деформации.Object of the Invention A device for determining stresses in stretched or squeezed rods by measuring the deformations with a strain gauge, is distinguished by the fact that a rod / -2, divided by a cross-section into two parts, is fitted with a tube 3, which is screwed at one end by means of rod parts, has an internal protrusion that can abut against a protrusion at the end of the second part of the rod, and is provided with a sleeve 4 screwed onto the free end with an internal protrusion that can abut against the second protrusion of the rod, in order to transfer force, Procedure in the rod, on the tube 3 and thus measuring its deformation.
