High-reliability loading mechanism with active metamorphic function

Abstract

The invention relates to a high-reliability loading mechanism with the active metamorphic function. One end of a movable arm of the loading mechanism is connected to a rack, the other end of the movable arm is connected with a bucket, one end of a driving rod is connected with the rack, the other end of the driving rod is connected with a first pull rod, and the other end of the first pull rod is connected with a supporting frame. One end of the supporting frame is connected with the rack, the other end of the supporting frame is connected with a second pull rod, and the other end of the second pull rod is connected with the bucket. One end of a first connecting rod is connected with the rack, the other end of the first connecting rod is connected with a second connecting rod, and the other end of the second connecting rod is connected with a supporting rod. A first locking device and a second locking device are installed on a ninth revolute pair and a twelfth revolute pair respectively. According to the high-reliability loading mechanism, a connecting rod transmission mechanism is adopted for replacing a hydraulic mechanism, so that the defects that the hydraulic mechanism is prone to oil leakage and complex are overcome; moreover, because the locking devices are adopted, active metamorphic operation can be carried out according to requirements of different working conditions, and the high-reliability loading mechanism is suitable for manufacturing various excavators and other engineering machines.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a high-reliability loading mechanism with an active metamorphosis function. Background technique [0002] Loader is a common construction machinery, mainly used in earthwork construction. Among them, the hydraulic loader is the most widely used one. However, the manufacturing cost of the hydraulic system is high, and it is prone to oil leakage, high maintenance costs, high noise, large vibration and other problems. These are long-term thorny problems of hydraulic loaders. The mechanical loader only replaces the hydraulic components with connecting rods, and the structure itself has not changed. The rationality of the replacement has not been considered comprehensively, which limits its practicability and reduces its reliability. [0003] With the development of modern engineering technology, the electromechanical technology and control technology have been greatly improved....
