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

Abstract

An electro-hydraulic hybrid planar three-activity controllable loading mechanism includes a boom lifting mechanism, a bucket control mechanism, and the like. The boom lifting mechanism is driven by an electric transmission system, which effectively reduces energy consumption compared with existing hydraulic loaders, and through the introduction of hydraulic components, the problem of unbalanced force on the two lifting and branch chains of the boom is effectively improved, and the load capacity is improved. Stability: due to the relatively small load of the bucket control mechanism, a relatively mature hydraulic cylinder is used to control the flipping of the bucket, which ensures the compact structure of the actuator. The loading mechanism not only has the characteristics of low energy consumption and high level of intelligence, but also has higher anti-vibration performance than the existing controllable loading mechanism, and is easy to realize overload protection, and has stronger practicability.

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...
