Electro-hydraulic hybrid type planar three-range-of-motion controllable loading mechanism

Abstract

An electro-hydraulic hybrid type planar three-range-of-motion controllable loading mechanism comprises a movable arm lifting mechanism, a bucket control mechanism and the like. The movable arm lifting mechanism is driven by an electric transmission system. The energy consumption is effectively reduced compared with an existing hydraulic loading machine. Through the introduction of hydraulic elements, the problem that stress of two lifting branched chains of a movable arm is unbalanced is effectively solved, and the bearing stability is improved. Since the load of the bucket control mechanism is small, a mature hydraulic cylinder is adopted to control a bucket to turn over, and the structure compactness of an actuation mechanism is guaranteed. The loading mechanism has the characteristics of being low in energy consumption and high in intelligence level, and compared with an existing controllable loading mechanism, the vibration resistance is higher, overload protection is achieved easily, and the practicability is higher.

Description

technical field [0001] The invention relates to the field of loaders, in particular to an electro-hydraulic hybrid plane three-movement controllable loading mechanism. Background technique [0002] Loader is a key equipment widely used in farmland, water conservancy, energy, municipal and other construction fields for bulk material loading and unloading, which plays an important role in infrastructure construction. However, traditional hydraulic loaders have high energy consumption and noise. Large, serious exhaust emissions, low level of intelligence and other shortcomings. The controllable mechanism is the product of the combination of traditional mechanism and electronic technology. The "Numerical Control Generation" equipment innovation project carried out in recent years has brought opportunities for the upgrading of traditional construction machinery technology. Aiming at the shortcomings of hydraulic loaders, the controllable mechanism and robot The relevant technolo...
