Multi-connecting-rod movable type loading mechanism with initiative metamorphic function

Abstract

The invention discloses a multi-degree-of-freedom multi-connecting-rod controllable mechanism type excavator. The multi-degree-of-freedom multi-connecting-rod controllable mechanism type excavator comprises a moving base plate, a rotary platform and a working device, wherein the working device comprises a large arm swinging mechanism, a bucket rod lifting mechanism and a bucket overturning mechanism; the large arm swinging mechanism comprises a large arm and a swinging mechanism; the bucket rod lifting mechanism comprises a bucket rod and a lifting mechanism; the bucket overturning mechanism comprises a bucket and an overturning mechanism. According to the multi-degree-of-freedom multi-connecting-rod controllable mechanism type excavator, mutual match movement of a movable arm lifting branch chain, a bucket rod swinging branch chain and a bucket overturning branch chain is realized under the matching effect of all driving rod driving states, so that all types of complicated excavation work is finished; the multi-degree-of-freedom multi-connecting-rod controllable mechanism type excavator has the flexibility of the controllable mechanism type excavator and a connecting rod transmission part is simpler; the stress between each rod and the connection part is better and the construction cost of the excavator is reduced; the multi-degree-of-freedom multi-connecting-rod controllable mechanism type excavator is suitable for manufacturing various excavators and other engineering machinery.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a multi-link 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 complete complex a...

Problems solved by technology

[0006] The purpose of the present invention is to provide a multi-link 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 traditional hydraulic loaders, and overcome the traditional hydraulic loaders. 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
