Aerial operation car lifting mechanism

Abstract

The invention discloses a lifting mechanism of an aerial work vehicle, which belongs to the technical field of aerial work. Including the frame and the hanging basket parts; the upper rocker and the lower rocker are hinged on the frame, and the connecting rod is connected between the upper rocking rod and the lower rocking rod; one end of the connecting rod is hinged with the hanging basket part; the upper rocking rod A pulley is installed on the top, and the hinge axis of the upper rocker and the connecting rod coincides with the rotation axis of the pulley; a pull rope is fixed at the hinge point of the lower rocker and the frame, and the other end of the pull rope bypasses the pulley and is connected to the hanging basket component; An oil cylinder is also hinged on the frame, and the piston rod of the oil cylinder is hinged with the upper rocker. The invention adopts a two-section arm structure and a lifting oil cylinder to realize the lifting of the hanging basket. The attitude of the hanging basket parts is adjusted by a pull rope. The hydraulic and control system is improved, avoiding the risk of the hanging basket being skewed due to failure of the hydraulic system and electrical system.

Description

technical field [0001] The invention relates to an aerial work vehicle, in particular to a lifting mechanism for an aerial work vehicle. Background technique [0002] Aerial work vehicles are widely used in municipal engineering, and the hanging basket of the existing aerial work vehicle needs to be leveled during the lifting process, so as to ensure that the personnel in the hanging basket can maintain an upright posture at any height. Aerial work vehicles with a leveling system are relatively complex, expensive, and there is a risk of hydraulic system and electrical system failure. Due to the use of the leveling system, the two-section boom aerial work vehicle needs to be driven separately by two oil cylinders, so as to obtain the required working height and realize the leveling of the hanging platform, the structure is complex, and the operation is cumbersome. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present inven...
