Abstract

A controllable symmetrical-and-parallel mechanism type loader comprises a main actuator chain with a closed-loop subchain and two parallel actuator subchains. The main actuator chain with the closed-loop subchain can control plane motion of a bucket space of a plane where main arm bars are located, and the actuator subchains perform controllable regulation on the bucket and control motions of turning up and down and the like of the bucket. The controllable symmetrical-and-parallel mechanism type loader has the advantages that plane control can be realized through the synthetic motions of the main actuator chain with the closed-loop subchain, and the spatial motion of the bucket is realized through connection of the actuator subchains; the bucket space is good in dynamics performance, large in working space, good in balance performance, high in mechanical reliability, compact in mechanism and simple to control; the member bars can be made into light bars acting on more occasions; the loader is driven fully electrically and free of emissions and noise pollution.

Description

technical field [0001] The invention relates to the field of loaders, in particular to a loader with a controllable parallel symmetrical mechanism. Background technique [0002] Construction machinery is a general term for construction machinery used in engineering construction, and loaders are one of the most important construction machinery. The loader is flexible and convenient in action, and can reduce the labor intensity of personnel. It is widely used in earthwork construction machinery for roads, railways, buildings, mines and other construction projects. It is also suitable for rural clean construction and convenient for personnel to load. It is mainly used for shovel loading Soil, gravel and other materials can also be used for light shoveling operations on ore and hard soil. There are two types of loaders: hydraulic and mechanical. Hydraulic loaders are widely used in various fields because of their good mobility and high flexibility. However, hydraulic loaders al...
