MDOF movable loading mechanism with initiative metamorphism function

Abstract

The invention discloses an MDOF movable loading mechanism with an initiative metamorphism function. The MDOF movable loading mechanism comprises a movable platform, a rack, a big arm lifting mechanism, a bucket turnover mechanism and two locking devices. The big arm lifting mechanism comprises a big arm and a lifting mechanism body. The bucket turnover mechanism comprises a bucket and a turnover mechanism body. The locking devices are installed on a revolute pair, the initiative metamorphism function can be achieved by locking the revolute pair, and the movement function can be achieved through the movable platform. According to the MDOF movable loading mechanism, a traditional hydraulic transmission mechanism is replaced by a novel connecting rod transmission mechanism, so the defects that a hydraulic system of a hydraulic loading machine is complex, prone to oil leakage, high in requirement for machining precision and the like are overcome. Due to the fact that the locking devices are adopted in the revolute pair, the MDOF movable loading mechanism can perform initiative metamorphism according to different operation conditions, and not only has the flexibility of the hydraulic loading machine, but also can achieve loading operation of two degrees of freedom by utilizing one initiative rod; meanwhile, the MDOF movable loading mechanism has the movement function and an operation function, thereby being suitable for manufacturing various loading machines and other engineering machines.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a multi-degree-of-freedom mobile loading mechanism with an active metamorphosis function. Background technique [0002] Loader is a kind of common engineering machinery, which is widely used in earthwork construction of construction projects such as roads, railways, buildings, hydropower, ports, and mines. Among them, the hydraulic loader is the most widely used type of loader, 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 the hydraulic loader. [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 actions, and can compl...

Problems solved by technology

[0006] The purpose of the present invention is to provide a multi-degree-of-freedom mobile 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 cost of the traditional hydraulic loader. High, high operating noise, high cost of hydraulic components, and insufficient response, etc., the number of active rods should also be reduced to reduce the number of controllable motors and reduce the manufacturing cost of the loading mechanism
