Abstract

The invention relates to the technical field of high-altitude operation equipment, discloses a hydraulic system of a hydraulic aerial cage, and solves the problem that the service life of a hydraulic device of a hydraulic aerial cage is shortened due to the fact that the hydraulic device of the hydraulic aerial cage does not have cooling and filtering operations. A hydraulic aerial cage body is included; a supporting frame is arranged at the top end of the hydraulic aerial cage body; the top end of the supporting frame is movably connected with a main hydraulic cylinder; an output shaft of the main hydraulic cylinder is connected with a telescopic rod; one end of the telescopic rod is connected with a connector; one side of the connector is movably connected with a connecting support; an insulating oil hydraulic rod is arranged at one end of the connecting support; one end of the insulating oil hydraulic rod is connected with a mounting frame; a hanging basket is mounted on the mounting frame; and oil tanks are arranged at the top ends of the mounting frame and the hydraulic aerial cage body; Through the effect of a filter, impurities in oil are effectively filtered, then the cleanliness of the oil is improved, convenience is brought to work of the main hydraulic cylinder and the insulating oil hydraulic rod, and the service life of the main hydraulic cylinder and the service life of the insulating oil hydraulic rod are effectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of aerial work equipment, in particular to a hydraulic system of an aerial work vehicle. Background technique [0002] Aerial work vehicles have a wide range of applications. Usually, aerial work vehicles include a boom set on the car body and a working bucket or working device installed at the end of the boom. The staff enters the working bucket and uses the boom to move The working bucket and the staff or the working device are sent to a high place for high-altitude operations. [0003] However, the hydraulic device of the existing aerial work vehicle cannot cool and filter the hot oil generated during work, which will cause damage to the hydraulic device of the aerial work vehicle, thereby shortening the service life of the aerial work vehicle. Contents of the invention [0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a hydraulic...
