Abstract

The invention relates to a control technique, and in particular relates to a control technique of a hydraulic aerial cage, aiming at realizing automatic rescue preparation and reclaiming of the hydraulic aerial cage. The embodiment of the invention also provides a control system of the hydraulic aerial cage. The control system comprises a landing leg length sensor of each landing leg, at least one inclination angle sensor, a cantilever crane length sensor of each cantilever crane, a cantilever crane angle sensor of each cantilever crane, a range finder, a get-off programmable controller and a get-on programmable controller. According to the automatic rescue preparation in high altitude reclaiming and a reclaiming control method provided by the embodiment of the invention, operating personnel does not need to do complex operation, and the system carries out the operation completely automatically, so that the control precision on the reclaiming at the high altitude is improved, and the intensity of manual operation is reduced; and the precise control is carried out by the sensors and detection signals of limiting switches, thereby avoiding the damage, caused by excessive operation, to machinery.

Description

technical field [0001] The invention relates to a control technology, in particular to a control technology of an aerial work vehicle. Background technique [0002] Aerial work vehicles are widely used in ships, construction, municipal construction, fire protection, port freight, wind power, landscaping and other fields. At present, there are more and more applications of aerial work vehicles with super large heights. This vehicle is mainly a structure with a car chassis and double-folding multi-telescopic working arms. Due to the structural characteristics of the super-height aerial work vehicle, when the vehicle is in the driving state, the working platform is retracted at the rear of the vehicle body, and the height from the ground is high. It is very difficult for the operator to go up to the working platform without stairs. It is not safe to force climb. Therefore, the working bucket must be operated to the rescue preparation state under the premise that the chassis ...
