Способ определения остаточных напряжений в сжатых полках арочных стальных тонколистовых холоднокатаных профилированных листов

FIELD: construction. SUBSTANCE: invention relates to the field of structural mechanics and can be used in designing bearing arched coatings from thin-sheet cold-bent profiled sheets. Method for determination of residual stresses in compressed shelves of arched steel thin-sheet cold-rolled shaped sheets consists in the fact that in the compressed shelf of arched steel thin-sheet cold-rolled profiled sheet through cuts are made in the form of two parallel cuts oriented along the profile of sawing in the investigated shelf and through cuts in the form of sawing oriented across the profile in the middle of design length and along edges, with further measurement of physical parameters (deflection) by micrometer and calculation of residual stresses by formula. Use of operations (making cuts) allows sufficiently fast, without using special equipment, to determine residual stresses in compressed shelves of arched cold-rolled profiled sheets. EFFECT: improvement of existing method for determination of residual stresses, simplification of calculations, as well as improvement of accuracy of measurement of deflections. 1 cl, 4 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 708 551 C1 (51) МПК G01L 1/06 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК G01L 1/06 (2019.08) (21)(22) Заявка: 2018142956, 04.12.2018 (24) Дата начала отсчета срока действия патента: Дата регистрации: Приоритет(ы): (22) Дата подачи заявки: 04.12.2018 (45) Опубликовано: 09.12.2019 Бюл. № 34 2 7 0 8 5 5 1 R U (56) Список документов, цитированных в отчете о поиске: RU 2455622 C1, 10.07.2012.

Measuring static or dynamic compression e.g. on wheels - using hard pressure exerter against body of known impressibility

The arrangement provides a simple and compact device for measuring static or maximally occuring dynamic compressive stress e.g. for making lateral force measurements in vehicle wheels during normal operation. The arrangement consists in subjecting a measurement body (4) whose susceptibility to indentation is already known, to deformation by a harder pressure-exerting body (5). The latter is held by a retaining piece (6) so that it projects against the measurement body. The latter may be circular or bar-shaped while the pressure body may be spherical, conical or the same shape as the measurement body. The retainer and pressure body may be in one piece.

Interchangeable overload indicator for load chains - consists of two pawls enclosing chain connected by calibrated shear pins

An interchangeable load chain overload monitor consists of a calibrated multiple component monitor unit connecting two pawis enclosing part of the chain. Overloads are indicated by deformation of the unit. Its application does not require chain link separation and results in a negligible reduction in chain length. Its operation does not require post-overload measurements. The monitoring elements consist of draw or shear pins connecting the two pawls on either side of the chain.

LOAD DETECTION & INDICATION

Overload detection

An overload detecting assembly comprises a first load bearing member (10) adapted to flex laterally in response to a load to be monitored, a second load bearing member (11) spaced from the first under normal load conditions and which is contacted and loaded by the first load bearing member (10) when it is loaded beyond a load limit. Preferably, the first load bearing member (10) has a yield point below the load limit and takes a permanent set once the yield point has been exceeded. A lateral probe (18) cooperates with the first load bearing member as it moves towards the second load bearing member and in turn deflects an indicator member (20) which takes a permanent set when a yield point is exceeded. Ready inspection of the indicator member then reveals whether or not it has been bent.

Overload detection

An overload detecting assembly comprises a first load bearing member ( 10 ) adapted to flex laterally in response to a load to be monitored, a second load bearing member ( 11 ) spaced from the first under normal load conditions and which is contacted and loaded by the first load bearing member ( 10 ) when it is loaded beyond a load limit. Preferably, the first load bearing member ( 10 ) has a yield point below the load limit and takes a permanent set once the yield point has been exceeded. A lateral probe ( 18 ) cooperates with the first load bearing member as it moves towards the second load bearing member and in turn deflects an indicator member ( 20 ) which takes a permanent set when a yield point is exceeded. Ready inspection of the indicator member then reveals whether or not it has been bent.

Slope monitoring device

A slope monitoring device includes a cable anchored at one end to the sloped wall of an open pit mine, dump, or the like. The cable extends over an idler pulley at the top of the sloped wall and passes around a further pulley coupled to an optical shaft encoder which generates a digital signal corresponding to the angular position of the pulley. The cable is engaged by a clutch and is wound about a play-off reel, each secured to a weighted sleeve slidingly extending about a vertical post. The weighted sleeve maintains tension upon the cable, while the clutch allows additional cable to be played off of the reel when tension is increased due to movement of the wall. The shaft encoder information, along with the temperature, battery condition, and cable condition, are transmitted by radio to a remote location for processing.
