Abstract
Телескопическая мачта для антенных или иных устройств, содержащая входящие одна в другую секции и подъемник, отличающаяся тем, что подъемник выполнен в виде телескопического гидроцилиндра двухстороннего действия с двумя штуцерами в плунжерной части для подвода гидравлической жидкости, телескопический гидроцилиндр двухстороннего действия установлен внутри секций телескопической мачты и закреплен одним концом в основании неподвижной секции а вторым концом в основании последней подвижной секции и имеет суммарный рабочий ход, равный высоте подъема подвижных секций, на входе штуцеров установлены гидрозамки (управляемые обратные клапаны), при этом канал управления каждого гидрозамка соединен с напорной магистралью противоположного гидрозамка.A telescopic mast for antenna or other devices, comprising one section of the other and a lift, characterized in that the lift is made in the form of a telescopic double-acting hydraulic cylinder with two fittings in the plunger part for supplying hydraulic fluid, a double-acting telescopic hydraulic cylinder is installed inside the sections of the telescopic mast and fixed at one end at the base of the fixed section and the second end at the base of the last movable section and has a total stroke equal to At a height of lifting of the movable sections, hydraulic locks (controlled check valves) are installed at the inlet of the fittings, while the control channel of each hydraulic lock is connected to the pressure line of the opposite hydraulic lock.
