Description
например, при разгрузке вибробадьи или извлечепии свай из грунта, нагрузка от массы груза и действие возмущающей силы источника вибрации передаетс через крюк 5, демпфер 4 и клип 3 упругим призмам 2. For example, when unloading the vibrobadia or extracting piles from the ground, the load from the mass of the load and the action of the disturbing force of the source of vibration are transmitted through hook 5, damper 4 and clip 3 to elastic prisms 2.
При максимальной нагрузке на крюке 5 полый клин будет находитьс в положении и жесткость упругих призм 2 будет максимальной, по мере умеиьщени нагрузки (разгрузка вибробадьи) происходит подъем клипа и в работу включаетс дополнительный объем упругих призм, расположенный под клином. Это приводит к Зменьшению жесткости упругих призм 2.At maximum load on the hook 5, the hollow wedge will be in position and the rigidity of the elastic prisms 2 will be maximum, as the load decreases (unloading the vibrobad), the clip is lifted and an additional volume of elastic prisms located below the wedge is put into operation. This leads to a decrease in the stiffness of the elastic prisms 2.
Таким образом, происходит автоматическое регулирование жесткости упругого элемента крановой подвески.Thus, there is an automatic regulation of the stiffness of the elastic element of the crane suspension.
В переходных режимах работы вибровозбудител происходит дополнительное гащение колебаний демпфером 4.In transient modes of the vibration exciter there is an additional damping of the oscillations by the damper 4.
Предлагаема подвеска позволит изолировать конструкцию грузоподъемных мащин от воздействи вибрации, уменьшить динамические нагрузки в переходных режимах работы механизма подъема и вибровозбудител . Уменьшитс количество неплановых ремонтов и технических обслуживании , увеличитс срок службы крана и улучшатс услови работы машиниста.The proposed suspension will allow to isolate the design of the load-lifting machines from the effects of vibration, to reduce the dynamic loads in transient modes of operation of the lifting mechanism and the vibration exciter. The number of unplanned repairs and maintenance will decrease, the service life of the crane will increase, and the driver's working conditions will improve.
Экономический эффект от внедрени предполагаемого изобретени ориентировочно составит 1040 руб. в год на одной машине грузоподъемностью 10 тс.The economic effect from the implementation of the proposed invention is approximately 1040 rubles. per year on one machine with a carrying capacity of 10 ton.
