Abstract

FIELD: machine building.
SUBSTANCE: device contains linear displacement probe of hand truck and indicator unit, indicating cargo weight. Device is outfitted by permanently stringed rope, straightness of which is held permanently independently of bending deflection of bridge. Stringed rope by one end is rigidly fixed on bridge of crane, by the second end it is connected to tensioning device, and to the middle of rope it is fixed draw bar, connected to counting device of linear displacement probe.
EFFECT: increasing of accuracy and safety of cargo weighting lifted by bridge crane.

Description

Предлагаемое изобретение относится к подъемно-транспортному машиностроению, а именно к устройствам для определения веса груза, поднимаемого мостовым краном. Известно устройство для определения веса груза мостового крана (авторское свидетельство СССР №1299947 А1, кл. В66С 13/16).The present invention relates to hoisting and transport machinery, and in particular to devices for determining the weight of a load lifted by an overhead crane. A device for determining the weight of the cargo of an overhead crane (USSR author's certificate No. 1299947 A1, class B66C 13/16).

Недостатком данного устройства является то, что деформируется не только мост крана, но и неравномерно колесные пары передвижения моста, не учитывается пластическая деформация путей под колесными парами при подъеме груза.The disadvantage of this device is that not only the crane bridge is deformed, but also the wheel pairs of the bridge moving unevenly, the plastic deformation of the paths under the wheel pairs when lifting the load is not taken into account.

Цель предлагаемого изобретения: повышение точности взвешивания, постоянный контроль моста крана, предотвращение поднятия груза, превышающего номинальный вес.The purpose of the invention: improving the accuracy of weighing, constant monitoring of the bridge of the crane, preventing the lifting of loads in excess of the nominal weight.

На фиг.1 изображена функциональная схема устройства. Устройство для определения веса груза мостового крана содержит постоянно натянутый трос 5, который одним концом жестко закреплен на мосту крана 1, а второй конец соединен с натяжным устройством, фиг.2. К середине троса прикреплена тяга 4, соединенная с отсчитывающим устройством 3.1 измерителя линейного перемещения 3. Шкала 3.2 измерителя линейного перемещения закреплена на мосту крана. Индикатор 6 показывает вес груза.Figure 1 shows the functional diagram of the device. A device for determining the weight of the load of an overhead crane contains a constantly stretched cable 5, which is rigidly fixed at one end to the bridge of the crane 1, and the second end is connected to the tensioning device, Fig.2. A rod 4 is connected to the middle of the cable and connected to the reading device 3.1 of the linear displacement meter 3. The scale 3.2 of the linear displacement meter is fixed to the crane bridge. Indicator 6 shows the weight of the load.

Устройство работает следующим образом.The device operates as follows.

Тележка 2 с грузом, проходящая через середину моста, деформирует его. Шкала вместе с мостом перемещается вниз. Отсчитывающее устройство при этом остается неподвижным, так как трос за счет натяжного устройства сохраняет прямолинейность. Величину деформации, которая пропорциональна весу груза, отсчитывающее устройство передает на индикатор.Trolley 2 with cargo passing through the middle of the bridge deforms it. The scale along with the bridge moves down. The counting device in this case remains stationary, since the cable due to the tensioning device remains straightforward. The amount of deformation, which is proportional to the weight of the load, the counting device transmits to the indicator.
