Embodiment 1

[0008] The aerial work vehicle leveling system of the present invention is composed of an angle sensor 1 connected in sequence, a controller 7, an electro-hydraulic proportional reversing valve 6, a balance valve 5, and a leveling hydraulic cylinder 3, wherein the angle sensor 1 is set at the working At the bottom of the platform 2, the leveling hydraulic cylinder 3 is connected with the arm rod 4.

[0009] The magnitude of the output signal of the angle sensor 1 is proportional to the inclination angle of the working platform 2 . When the boom 4 changes amplitude, the working platform 2 forms a certain angle with the horizontal plane, and the angle sensor 1 outputs a signal of a corresponding magnitude. After being processed by the controller 7, it is input to the electro-hydraulic proportional reversing valve 6 by the driving circuit. The spool of the electro-hydraulic proportional reversing valve 6 is displaced to output pressure oil. The flow rate of the pressure oil is p...

Abstract

The invention provides a control device of an overhead working truck working platform. An overhead working truck leveling system is formed by sequentially connecting an angle sensor, a controller, an electro-hydraulic proportional reversing valve, a balance valve and a leveling hydraulic cylinder, wherein the angle sensor is arranged on the bottom of the working platform, and the leveling hydraulic cylinder is connected with an arm lever. The overhead working truck leveling system enables a leveling process to be continuous and stable in use, and is good in leveling performance, high in control precision, quick in dynamic response and easy to popularize.

Description

technical field [0001] The invention aims to provide a control device for a working platform of an aerial work vehicle. Background technique [0002] The working platform of the aerial work vehicle often needs to be leveled during the operation process. At present, it is manually controlled by manpower, the leveling effect is poor, and the process is time-consuming. Contents of the invention [0003] The invention aims to provide a leveling system for an aerial work vehicle which is easy to use and has good effect. [0004] The aerial vehicle leveling system of the present invention is composed of an angle sensor, a controller, an electro-hydraulic proportional reversing valve, a balance valve, and a leveling hydraulic cylinder connected in sequence, wherein the angle sensor is arranged at the bottom of the working platform, and the leveling The hydraulic cylinder is connected to the boom. [0005] The leveling system of the aerial work vehicle described in the present ...
