Problems solved by technology

This solution is not suitable for application scenarios where continuous lifting is controlled by a central controller, and it is difficult to ensure the stability of the lifting mechanism when the load is heavy
[0004] Chinese invention patent application CN104942826A "A Robot Lifting Device and Lifting Method" discloses a robot lifting scheme that adopts a pull rope plus a multi-stage slide rail. It is suitable for larger robots, and its stability will be reduced for small robots with large telescopic distances. In addition, the patent application for this invention uses a pull rope for lifting. The pull rope is used not only for lifting power transmission, but also as a load-bearing rope for each sliding arm. During the lifting process, the pull rope is easy to shake, making the robot's lifting not stable enough

Abstract

The invention provides a linkage type telescopic arm. The linkage type telescopic arm comprises a driving device, a fixed cylinder and at least one stage of telescopic device, wherein a linear groove and a spiral groove are arranged in the inner wall of the fixed cylinder along the axis, and the telescopic device comprises a rotating cylinder and a translation cylinder; linear grooves and spiral grooves are also designed on the rotating cylinder and the translation cylinder according to design requirements; and the fixed cylinder, the rotating cylinder and the translation cylinder are sequentially nested. By adopting a multi-stage spiral cylinder step-by-step propelling manner and utilizing the fit of the spiral grooves and the linear grooves, the linkage type telescopic arm realizes ordered telescoping, has a large telescoping range in a small space and can realize demanded elongation in a limited space. The linkage type telescopic arm is compact in structure and light in weight and realizes step-by-step linkage telescoping. A telescopic mechanism meeting the requirements of specific product applications has a compact structure and a small size and can be elongated to a required length in the limited space.

Description

technical field [0001] The invention relates to a linked telescopic arm. Background technique [0002] During the daily power station inspection, sometimes the objects inspected by the inspection robot are in a relatively distant location, but cannot be reached due to path restrictions. Therefore, the camera is stretched out through the telescopic mechanism to reduce the distance from the inspected object. However, due to the complex and large structure of the conventionally designed spiral telescopic mechanism, it cannot effectively and quickly perform telescopic movement, and is accompanied by problems such as a high failure rate, resulting in low inspection efficiency. [0003] Chinese invention patent document CN102235840A "A Lifting System for Target Lifting Robot" describes a lifting system using spring control materials. The positioning method is switch positioning, and the pushing rod and relay post interact to complete the lifting function. This device is suitable ...
