Description

Изобретение представл ет собой устройство дл  автоматического Перемещени  противовеса в пловучих кранах при отклонении стрелы крана от продольной оси понтона.The invention is a device for automatically displacing the counterweight in floating cranes when the boom of the crane deviates from the longitudinal axis of the pontoon.

Известны подобные устройства, в которых перемещение противовеса пропорционально крену понтона. Эти устройства, однако, не реагиру ют на изменение положени  стрелы крана относительно продольной оси понтона.Such devices are known in which the displacement of the counterweight is proportional to the pontoon roll. These devices, however, do not respond to a change in the position of the boom of the crane relative to the longitudinal axis of the pontoon.

В предложенном устройстве перемещение противовеса происходит пропорционально и синхронно углу поворота стрелы крана в горизонтальной плоскости.In the proposed device, the displacement of the counterweight occurs in proportion and synchronously to the angle of rotation of the boom of the crane in the horizontal plane.

На фиг. 1 и 2 схематически изображено описываемое устройство в двух проекци х.FIG. Figures 1 and 2 schematically depict the described device in two projections.

Кран, установленный поворотно в центре понтона на поворотном круге }, снабжен эксцентриком 2, насаженным на ось вращени  крана и приводимым во вращение при поворотах крана стержнем 3, св занным с рамой кабины крана. Бугель 4 эксцентрика 2 св зан в диаметральнопротивоположных точках со щтоками 5 двух гидравлических цилиндров о насоса, порщии которых расположены на равном рассто нии от оси эксцентрика.A crane mounted pivotally in the center of the pontoon on the turntable} is equipped with an eccentric 2, mounted on the axis of rotation of the crane and driven by the rotation of the crane with a rod 3 connected to the frame of the crane cabin. An eccentric yoke 4 is connected at diametrically opposite points with the shafts 5 of two hydraulic cylinders on the pump, the cavities of which are located at an equal distance from the eccentric axis.

При вращении крана бугель 4 эксцентрика толкает щтоки 5 цилиндров 6, застав.т   жидкость из одного цилиндра по трубопроводу 7 перетекать под давлением в соответствующий из рабочих удлиненных цилиндров 8.When the crane rotates, the yoke 4 of the eccentric pushes the rods 5 of the cylinders 6, force the liquid from one cylinder through the pipeline 7 to flow under pressure into the corresponding of the working elongated cylinders 8.

Порщни удлиненных цилиндров 8 св заны зубчатой рейкой 9, посредством которой приводитс  во враидение зубчатое колесо, сид щее на одной оси с барабаном 10. Бесконечный канат 11, намотанный в несколько витков на барабан 10, переход  через блоки 12, приводит в движение балластную тележку /с, перемещающуюс  в трюме крана от борта к борту по рельсам 14.The cylinders of the elongated cylinders 8 are connected by a toothed rack 9, by means of which a gear wheel is mounted, which sits on the same axis with the drum 10. An endless rope 11 wound in several turns on the drum 10, passing through the blocks 12, drives the ballast trolley / c. moving in the crane hold from side to side on rails 14.

При положении стрелы крана, перпендикул рном борту, тележка будет находитьс  у противоположного от конца стрелы борта. При полоWhen the boom of the crane is positioned perpendicular to the side, the cart will be located at the side opposite to the end of the boom. With polo
