Multi-unit connection rod driving type heavy-duty loading robot with three rocker arms

Abstract

A multi-unit link-driven heavy-duty loading robot with three pairs of rocker arms, including a multi-unit link drive mechanism, a boom lifting mechanism, a bucket control mechanism, and the like. Under the control of the computer, the multi-unit connecting rod drive mechanism realizes the drive of multiple small-power motors, high-power, high-torque power output, and meets the power requirements of the loading robot for high-load operations. By introducing hydraulic components into the boom lifting mechanism and the bucket control mechanism, the pressure in the cylinder is equalized, the problem of unbalanced force on the two drive chains of the loading robot bucket and the boom is improved, and the load stability is improved. The loading robot not only has the characteristics of high mechanical efficiency, fast response, high motion precision, and good controllability, but also the planar parallel design of the bucket control mechanism, and the introduction of multi-unit linkage drive mechanism and hydraulic components have greatly improved its performance. Bearing capacity and anti-vibration performance, and easy to realize overload protection function, it is more suitable for manufacturing heavy-duty and high-load loading robots.

Description

technical field [0001] The invention relates to the field of loaders, in particular to a multi-unit link-driven heavy-duty 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 is a...
