Изобретение относитс к средствам управлени и может быть использовано дл управлени многоприводными подъемно-транспортными установками, например , конвейерами с гибким т говым 5 органом.:The invention relates to control means and can be used to control multi-drive lifting and transporting installations, for example, conveyors with a flexible body 5:
Известно устройстводл управлени конвейером с измерением скорости движени конвейерной ленты с использова- нием магнитопровод щих меток, включа-Ю ющее магнитопроврд щие метки в ленте и магнитопровод, св занный с индук- . ционным датчиком, расположенным под лентой l.A device for controlling a conveyor is known that measures the speed of movement of a conveyor belt using magnetic conductors, including magnetic conductive marks in the belt and the magnetic conductor associated with the inductor. sensor located under the tape l.
Недостатком устройства вл етс t5 низка точность контрол скорости, а следовательно и т говых усилий, передаваемых приводными барабанами ленте этим устройством, низка из-за малой частоты следовани магнитопровод щих 20 меток и отсутстви учета общей выт жки ленты при изменени х .нагрузки. Кроме того, износ краев ленты, происход щий при эксплуатации, и исчезновение из-за этого меток, снижает на- 25 дежность работы устройства.The drawback of the device is that t5 has low accuracy in controlling the speed and, consequently, the thrust force transmitted by the driving drums of the tape by this device, is low due to the low frequency of the conductive 20 marks and the fact that the total draw of the tape is not taken into account when the load changes. In addition, the wear of the edges of the tape, which occurs during operation, and the disappearance of marks due to this, reduces the reliability of the device.

Известное устрюйство имеет сравнительно низкую точность регулировани т говых моментов, а,.следовательно и т говых усилий приводных барабанов , т. к. не учитывает выт жку т гового органа при изменении нагрузки на него, а значит и не обеспечивает достаточную надежность управлени конвейерной установкой.The well-known device has a comparatively low control accuracy of the driving moments, and, consequently, the driving forces of the driving drums, since it does not take into account the pull of the traction body when the load on it changes, and therefore does not provide sufficient reliability of control of the conveyor installation.
Целью предлагаемого изобретени вл етс повышение точности и надежности управлени многоприводной подъемно-транспортной установкой с гибким т говым органом за счет распределени т говых усилий между приводны- ми барабанами в зависимости от изменени нагрузки на т говом органе.The aim of the invention is to improve the accuracy and reliability of controlling a multi-drive lifting and transporting installation with a flexible traction body by distributing the tractive effort between the driven drums depending on the load change on the traction device.
