Controllable mechanism type loading machine with active metamorphic function

Abstract

A controllable mechanism type loading machine with the active metamorphic function comprises a machine frame, a bucket turnover mechanism, a big arm lifting mechanism and a locking device. 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 device is installed on a rotation pair, and the active metamorphic function is achieved by locking the rotation pair. A novel connecting rod transmission mechanism replaces a traditional hydraulic transmission mode, and the shortcomings that a hydraulic system of a hydraulic loading machine is complex, oil leakage occurs easily and the requirement for machining accuracy is high are overcome. As the locking device is arranged on the rotation pair, active metamorphosis can be achieved according to different operating conditions. The controllable mechanism type loading machine not only has the flexibility of a novel connecting rod loading machine, but also can achieve the loading operations of two degrees of freedom by the utilization of one driving rod, the number of motors used on the machine is decreased, the manufacturing price of the loading machine is lowered, and the controllable mechanism type loading machine is applicable to manufacturing various loading machines and other engineering machines.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a controllable mechanism loader with an active cell transformation function. Background technique [0002] Loader is a kind of earth and stone construction machine widely used in construction projects such as road, railway, construction, hydropower, port, mine. Among them, the hydraulic loader is the most widely used type of loader, but the manufacturing cost of the hydraulic system is high, oil leakage is prone to occur, and maintenance is difficult. 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 mechanical mechanism provides a broad development space for construction machinery. The multi-degree-of-freedom controllable mechanism driven by the motor not only has a large working space, flexible movement, and high reliability. At the same time, it al...

Problems solved by technology

[0004] The purpose of the present invention is to provide a controllable mechanism loader with the function of active cell transformation. First, it should have the advantages of large working space, large loading capacity and good force of the traditional hydraulic loader, and overcome the maintenance cost of the traditional hydraulic loader. high operating noise, high cost of hydraulic components, and insufficient response. At the same time, the number of active levers used should be reduced, thereby reducing the number of controllable motors, reducing the manufacturing cost of the loading mechanism, and improving the simultaneous operation of multiple motors. The coupling vibration caused by it improves the service life of the parts and the reliability of the mechanism
