Multi-unit linkage-drive planar 3-acitivity face-shovel loading robot

Abstract

A multi-unit linkage-driven planar 3-acitivity face-shovel loading robot comprises a multi-unit linkage-drive mechanism, a movable arm lifting mechanism, a bucket control mechanism, and the like. Under the control of a computer, the multi-unit linkage-drive mechanism is driven by a plurality of low-power motors, the high-power and high-torque power output is achieved, and then the high-loading operation power demand of the loading robot is met; based on the Pascal's law, the same in-cylinder pressure is achieved by introduction of hydraulic elements into the movable arm lifting mechanism, thereby effectively solving the problem that two drive chains of lifting movable arms of a conventional controllable loading mechanism are subjected to uneven pressure and improving the bearing stability; the loading robot has not only the high-transmission-efficiency, high-response-speed, high-motion-accuracy, high-controllability and other characteristics of the conventional controllable loading mechanism, but also better bearing and anti-vibration properties by introduction of the multi-unit linkage-drive mechanism and the hydraulic elements; meanwhile, the overload protection function is easy to achieve; and such technical scheme is very suitable for manufacturing of large-, medium- 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 plane three-movement front shovel 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 a...
