Multi-freedom-degree controllable loading mechanism with active metamorphic function

Abstract

The invention discloses a multi-freedom-degree controllable loading mechanism with an active metamorphic function. The multi-freedom-degree controllable loading mechanism comprises a frame, a big arm lifting mechanism, a bucket turnover mechanism and two locking devices, wherein the big arm lifting mechanism comprises a big arm and a lifting mechanism; the bucket turnover mechanism comprises a bucket and a turnover mechanism; the locking devices are mounted on revolute pairs, and are used for realizing the active metamorphic function through locking the revolute pairs. According to the invention, as a novel connecting rod transmission mechanism is adopted to replace a traditional hydraulic transmission mechanism, the defects of complexity in a hydraulic system of a hydraulic loading machine, easiness in oil leakage and high processing accuracy requirement are overcome; as the locking devices are adopted on the revolute pairs, active metamorphic operation can be performed according to different operation conditions, flexibility of the hydraulic loading machine is realized, and loading operation under two freedom degrees can be realized by utilizing one driving rod, using amount of motors is reduced, the construction cost of the loading mechanism is reduced, and the multi-freedom-degree controllable loading mechanism is suitable for manufacturing of various loading machines and other engineering machinery.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a multi-degree-of-freedom controllable loading mechanism with an active metamorphosis function. Background technique [0002] Loader is a common construction machinery, which is widely used in earthwork construction of roads, railways, buildings, hydropower, ports, mines and other construction projects. Among them, hydraulic loaders are the most widely used type of loaders, but the hydraulic system is expensive to manufacture and prone to oil leakage. These are the long-standing thorny problems of hydraulic loaders. [0003] With the development of motor technology and the improvement of control technology, the controllable mechanism provides a broad development space for construction machinery. The multi-degree-of-freedom controllable mechanism driven by the control motor not only has a large working space, flexible action, and can complete complex and flexible The variabl...

Problems solved by technology

[0006] The purpose of the present invention is to provide a multi-degree-of-freedom controllable loading mechanism with the function of active cell transformation. First, it should have the advantages of large working space, large loading force, and good force of the traditional hydraulic loader, and overcome the maintenance of the traditional hydraulic loader. High cost, high operating noise, high cost of hydraulic components, and insufficient response, etc., should also reduce the number of active rods used to reduce the number of controllable motors and reduce the manufacturing cost of the loading mechanism
