Abstract

A multi-unit connection rod driving type three-range-of-motion loading robot with three rocker arms comprises a multi-unit connection rod driving mechanism, a movable arm lifting mechanism, a fork bucket control mechanism and the like. Under control of a computer, the multi-unit connection rod driving mechanism achieves driving of multiple small-power motors and high-power and high-torque power output, and meets the power requirement of high-load operation of the loading robot. On the basis of the Pascal principle, a hydraulic element is introduced to the movable arm lifting mechanism, equal in-cylinder pressure is achieved, the problem that stress on two driving chains for driving a movable arm of an original controllable loading mechanism is unbalanced is effectively solved, and the bearing stability is improved. The loading robot has the characteristics of being high in transmission efficiency, high in response speed, high in motion precision, good in controllability and the like as the original controllable loading mechanism, but also has better bearing performance and vibration resistance through introduction of the multi-unit connection rod driving mechanism and the hydraulic element, can achieve the overload protection function easily, and is quite suitable for manufacturing of large, intermediate and small-sized loading robots.

Description

technical field

[0001] The invention relates to the field of loaders, in particular to a multi-unit link-driven three-movement loading robot with three rocker arms. 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 technology ...
