Problems solved by technology

However, the current multi-link manipulator based on fixed hinge or sliding hinge structure cannot be fully unfolded or fully folded, and cannot adapt to places with large inspection arm span requirements and small inspection space, which significantly reduces the applicable places.
And it is impossible to achieve the maximum arm span and minimum folding size of the ordinary collaborative robot arm, and the current multi-link robotic arm based on the fixed hinge or sliding hinge structure is generally not easy to achieve internal wiring, which cannot meet the use requirements of some places
[0003] Neither of the above two lifting devices can well solve the needs of the current inspection field. Underactuated multi-link foldable inspection robot arm with low maintenance cost

Abstract

The invention discloses an under-actuated multi-link type foldable routing inspection mechanical arm which comprises a mechanical arm body. The mechanical arm body comprises a motor drive module piece, a rod assembly and a carrying table. The rod assembly is arranged on the motor drive module piece. The carrying table is arranged on the rod assembly. The motor drive module piece comprises a modulefixing frame and a driving motor. The driving motor is arranged on the module fixing frame. The rod assembly at least comprises two rod groups and a gear connecting box, wherein the two adjacent rodgroups are connected through the gear connecting box. The carrying table is arranged at the free end of the rod group on the uppermost side in the rod groups. The driving motor can drive the rod assembly to stretch out and draw back, so that use requirements are met. The whole mechanical arm is light in weight, easy to control, large in arm span, small in folding size, capable of realizing internal wiring, high in stability, low in manufacturing and use cost and low in maintaining cost.

Description

technical field [0001] The invention relates to the technical field of inspection robots, and more specifically, the invention relates to an underactuated multi-link foldable inspection robot arm. Background technique [0002] An inspection robot is a special robot used to conduct patrol inspections in a specific environment and collect relevant information. It is generally composed of a mobile platform and a lifting structure. At present, the lifting structures that are widely used in practice mainly include two types: hydraulically driven lifting and motor-driven lifting. The lifting structure driven by hydraulic pressure is generally used The lifting structure is generally used in light load, medium and high speed occasions. The lifting devices currently used in the field of inspection are generally powered by batteries due to the requirements of the use environment and application occasions, and the terminal load is relatively light, so it is more common to use motor dr...
