Description
(54) ДАТЧИК УСИЛИЙ(54) EFFORTS SENSOR
Изобретение относитс к устройствам, обеспечиваищим безопасную эксплуатацию краиов, а имеино к датчикам ограничителей грузоподъемности кранов.The invention relates to devices that ensure the safe operation of edges, and to sensors of cranes load limiters.
Известны датчики усилий, содержащие закрепленный на нагруженном узле крана динамометр 11.Known force sensors containing mounted on a loaded node of the crane dynamometer 11.
Однако такие динамометры не стабильны в работе из-за больших погрешностей при колебани х температуры окружающей среды.However, such dynamometers are unstable in operation due to large errors when ambient temperature fluctuates.
Целью насто щего изобретени вл етс повышение стабильности работы датчика при перепадах температур окружающей среды.The purpose of the present invention is to improve the stability of the sensor when ambient temperature drops.
Дл этого динамометр содержит расширительный стержень, закрепленный на нагружаемом узле крана посредством многоточечных подвесок.For this, the dynamometer contains an expansion rod fixed on the crane loadable node by means of multipoint suspensions.
Кроме того, кажда многоточечна подвеска содержит две накладки, щарнирно закрепленные на оси, установленной на конце расширительного стержн , расположенные силвлетрично относительно продольной оси .динамометра и шаршфно закрепленные свободными концами на нагружаемом узле крана.In addition, each multipoint suspension contains two pads, hingedly mounted on an axis mounted on the end of the expansion rod, located sylvatrichno relative to the longitudinal axis of the dynamometer and sharfnoy fixed free ends on the loaded node of the crane.
того, по меньшей мере, один конец динамометра вьтолнен с продольным пазом, в Moreover, at least one end of the dynamometer is complete with a longitudinal groove, in
котфом установлена с возможностью пфемещени посредством нажимного винта ось накладсж, кажда накладка выполнена из цилиндра с внутренней резьбой и взаимодействующей с ней нарезной шпильки.The cotta is installed with the possibility of feeding by means of a pressure screw; an axle is nonsuit, each lining is made of a cylinder with internal thread and a threaded rod interacting with it.
На фиг. 1 представлен динамометр, вид сверху; нв фиг. 2 - то же, вид сбоку.FIG. 1 shows a dynamometer, top view; HB FIG. 2 - the same, side view.
