Abstract

Изобретение относитс к области строительного производства и может быть использовано дл повышени эффективности обработки пластичной бетонной поверхности и в исследовательской работе по оценке динамики давлени диска, а также позволит повысить качество обработки поверхности. Рабочий орган заглаживающей машины содержит заглаживающий диск с контактами, закрепленными изолированно от него и размещенными по радиусу, щеточно-контактный узел 68, закрепленный на валу диска, промежуточные реле 34 - 38 с замыкающими и размыкающими контактами, источник 67 питани . Приспособление дл регулировани давлени выполнено в виде закрепленных на диске одним концом штанг 28, другие концы которых через ползуны 20 и 21 св заны с приводом черв чным валом, пускатели 59 и 60, блок 14 управлени электродвигателем 12. 7 ил.The invention relates to the field of construction industry and can be used to improve the processing efficiency of plastic concrete surfaces and in research work to assess the dynamics of the pressure of a disk, as well as to improve the quality of surface treatment. The working body of the smoothing machine contains a smoothing disk with contacts fixed insulated from it and placed radially, a brush-contact unit 68 fixed on the disk shaft, intermediate relays 34-38 with closing and opening contacts, power supply 67. The pressure control device is made in the form of rods 28 fixed to the disk with one end, the other ends of which are connected with a worm shaft drive through sliders 20 and 21, starters 59 and 60, motor control unit 12. 12 Il.
