Plane eight-rod three-activity electro-hydraulic controllable face shovel loading robot

Abstract

The invention provides a plane eight-rod three-activity electro-hydraulic controllable face shovel loading robot. The plane eight-rod three-activity electro-hydraulic controllable face shovel loading robot comprises a movable arm lifting mechanism, a bucket control mechanism and the like. According to the plane eight-rod three-activity electro-hydraulic controllable face shovel loading robot, a hydraulic element is introduced into the movable arm lifting mechanism, so that the in-cylinder pressure is equal, the problem that two lifting branched chains of a movable arm of the loading robot are unbalanced in stress is solved, and the bearing stability is improved; the characteristics of being high in transmission efficiency, response speed and moving precision, good in controllability and the like of an existing controllable loading mechanism are achieved; and in addition, the bearing capability and the anti-vibration performance of the loading robot are greatly improved by introducing the hydraulic element, an overload protection function is easy to achieve, the reliability and the practicability of the loading robot are greatly improved so that operation in places where the construction environments are bad can be achieved through the loading robot, and the hydraulic element is suitable for manufacturing large-size, medium-size and small-size loading robots.

Description

technical field [0001] The invention relates to the field of loaders, in particular to an electro-hydraulic controllable front shovel loading robot with eight rods and three degrees of activity. 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 r...
