Embodiment Construction

[0021] Such as figure 1 As shown, the automatic oil replenishment type isomorphic double-cylinder leveling system includes active cylinder 1, controller 2, proportional solenoid valve 3, passive cylinder 4, redundant inclination sensor 5, and redundant inclination sensor 5 is installed on the working platform of the aerial work vehicle. On the platform, the inclination angle of the working platform of the aerial work vehicle is detected in real time; the oil cylinder installed between the turntable and the boom is called the active cylinder 1, the oil cylinder installed between the boom and the working platform is called the passive cylinder 4, and the controller 2 , proportional solenoid valve 3 are installed on the turntable.

[0022] The active cylinder 1 and the passive cylinder 4 of the leveling system have the same structural size. The rodless cavity and the rod cavity of the two cylinders are connected respectively, and balance valves are respectively provided on the pa...

Abstract

The invention belongs to the technical field of hydraulic adjustment and particularly relates to an automatic oil feeding type isomorphic double-cylinder leveling system. The system comprises a driving cylinder, a controller, a proportional solenoid valve, a driven cylinder and a redundancy inclined angle sensor, wherein rodless cavities of the driving cylinder and the driven cylinder are communicated and rod cavities of the driving cylinder and the driven cylinder are communicated; the controller is respectively and electrically connected with the redundancy inclined angle sensor and the proportional solenoid valve; the redundancy inclined angle sensor is used for feeding a detection result back to the controller; an output signal of the controller drives the opening and closing of the proportional solenoid valve; the proportional solenoid valve (3) can be used for carrying out oil supplementation on oil leaking cavities in the driving cylinder (1) and the driven cylinder (4). With the adoption of the system, the leveling process is safe and convenient and does not need to be subjected to artificially interfered; the problem that a working platform of an overhead working truck is inclined, caused by leaking of oil, is solved.

Description

technical field [0001] The invention belongs to the technical field of hydraulic adjustment, and in particular relates to an automatic oil replenishment type homogeneous double-cylinder leveling system. Background technique [0002] The isomorphic double-cylinder leveling system is a kind of hydrostatic leveling system, which has a simple structure and stable action, and has a wide range of applications in the aerial work vehicle market. However, when there is leakage or when it is applied to the leveling of the boom-length aerial work vehicle, the leveling performance will be reduced, or even unusable. The industry adopts the method of manually replenishing oil when the working platform of the aerial work vehicle is tilted artificially. Come a lot of inconvenience and unsafe factors. Contents of the invention [0003] In order to overcome the technical problems existing in the prior art, the object of the present invention is to provide an automatic oil-replenishing homo...
