Abstract

The invention discloses a 12R controllable excavating mechanism capable of realizing big arm swinging through active and alternate metamorphism. The 12R controllable excavating mechanism comprises a frame, a big arm swinging mechanism, a bucket rod elevating mechanism, a bucket overturning mechanism and an electromagnetic locking device, wherein the big arm swinging mechanism comprises a big arm and a swinging mechanism; the bucket rod elevating mechanism comprises a bucket rod and an elevating mechanism; the bucket overturning mechanism comprises a bucket and an overturning mechanism; the electromagnetic locking device is arranged on a revolving pair; an active metamorphism function is realized through electromagnetic locking of the revolving pair. The conventional hydraulic transmission is replaced by a connecting rod transmission mechanism, so that the defects of complexity and easiness in oil leakage in a hydraulic system of a hydraulic excavator are overcome; the electromagnetic locking device is arranged on the revolving pair, and active metamorphism can be performed according to different operation conditions, so that the flexibility of the hydraulic excavator is realized; moreover, three-degree-of-freedom excavating operation can be realized through two driving rods, so that the manufacturing cost of the excavating mechanism is reduced. The 12R controllable excavating mechanism is suitable for manufacturing various excavating machines and other engineering machinery.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a 12R controllable excavating mechanism that actively alternates to realize the swing of a boom. Background technique [0002] Excavator is a common construction machine, which is mainly used in various earthwork constructions. Among them, the hydraulic excavator is the most widely used type of excavator, but the manufacturing cost of the hydraulic system is high, and problems such as oil leakage are prone to occur. These are long-standing thorny problems of hydraulic excavators. However, traditional single-degree-of-freedom mechanical excavators, commonly known as "electric shovels", can only achieve simple and unchangeable trajectory output, so they cannot be used in a wide range of fields like hydraulic excavators. [0003] With the development of motor technology and the improvement of control technology, the controllable mechanism provides a broad development space for...
