Multi-freedom-degree lifting mechanical arm

Abstract

The invention discloses a multi-freedom-degree lifting mechanical arm. The mechanical arm comprises a base, a stand column arranged on the base and a mechanical arm structure arranged on the stand column; the mechanical arm structure comprises a first rotating mechanism, a second rotating mechanism, a vertical sliding mechanism, a cantilever mechanism, a speed reduction motor, a swing arm mechanism and a machine head. The mechanical arm is reasonable in structural design, use of an oil pressure cylinder is reduced, and therefore technical shortcomings brought by the oil pressure cylinder can be overcome, and work efficiency is improved to a certain degree; meanwhile, the work range of a lifting machine can be effectively increased, positioning precision of heavy object lifting can be effectively improved, the noise of the lifting machine can be reduced, use stability and safety coefficients are improved, application is high, and practicability is good.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a multi-degree-of-freedom hoisting manipulator. Background technique [0002] At present, the small lifting equipment in China is composed of booms, turntables, frames, outriggers and other parts. The mechanical action of the small crane is realized through the actions of the boom luffing, telescopic, hoisting and other mechanisms, and the lifting operation is realized through the combination of different actions. Control requires human hands to press the hydraulic rod to control the expansion and contraction of the oil cylinder, which is inefficient, time-consuming and laborious, and the leakage of hydraulic oil cannot be completely avoided, causing pollution to the working environment; the movement process of the hoisting mechanism is noisy, the positioning accuracy is low, and heavy objects It is easy to swing and rotate during the lifting process, an...
