Multi-unit-linear-driven loading robot with three planar ranges of motion

Abstract

A multi-unit-linear-driven loading robot with three planar ranges of motion comprises a multi-unit-linear-driving mechanism, a movable arm lifting mechanism, a bucket control mechanism and the like. Multiple linear drivers are adopted by the multi-unit-linear-driving mechanism for driving, high-power and high-torque power output is achieved through cranks, and the power requirement of an executing mechanism is met. Hydraulic elements are introduced in the movable arm lifting mechanism, equal pressure in two cylinders is achieved, the problem of unbalanced stress on two driving chains for lifting movable arms in original controllable loading mechanisms is effectively solved, and the bearing stability of the movable arms is improved. the loading robot not only has the characteristics of high mechanical efficiency, high response speed, high moving precision, good controllability and the like of the original controllable loading mechanisms, but also has better bearing and shock-resisting performance due to introduction of the multi-unit-linear-driving mechanism and the hydraulic elements, an overload protection function can be easily achieved, and the technical scheme is quite suitable for manufacturing of large, medium and small loading robots.

Description

technical field [0001] The invention relates to the field of loaders, in particular to a multi-unit linear drive plane three-movement loading robot. 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 is applied to th...
