Telescopic power-assisted mechanical arm

Abstract

The invention discloses a telescopic power-assisted mechanical arm. A telescopic rod is connected with a mechanical hand, and the tail of the telescopic rod is provided with a tail pulley E; a fixed pulley G and a mouth fixed pulley F are arranged on the upper side of the outer wall of the tail of the telescopic rod, and an operating line bracket is arranged on the left side of the fixed pulley G; one end of an operating line is connected with a revolute pair A rotating together with the mechanical hand, and the other end of the operating line bypasses a fixed pulley H, the bottom side of the fixed pulley G, the mouth fixed pulley F and the tail pulley E, penetrates through a telescopic pipe cavity and is connected with the mechanical hand; a telescopic rod front section is provided with a revolute pair G' and F', and the revolute pair G' and F' is connected with a revolute pair D' and E'; the back end of a first claw tooth and the back end of a second claw tooth bypass the revolute pair D' and E' and are connected with a revolute pair B' and C'; the revolute pair B' and C' is connected with the operating line after being fixed; a connecting piece rotates around the revolute pair G' and F', so that opening and closing of the mechanical hand are achieved; when a telescopic back section clockwise rotates around the revolute pair A, the telescopic rod is shortened; and the carrying efficiency is improved, and a person is prevented from bending down repeatedly.

Description

technical field [0001] The invention belongs to the technical field of transportation assistance, and in particular relates to a telescopic assistance mechanical arm. Background technique [0002] The overall scale of the logistics industry is growing rapidly, and the handling intensity of couriers is also increasing. The goods that have been moved need to be rearranged and distributed, and they will be exhausted after carrying them back and forth several times. With the vigorous development of the logistics and transportation industry, more and more cargo handling tasks have brought great inconvenience to couriers. It consumes a lot of physical strength of the courier personnel, and simply relying on increasing manpower cannot fundamentally solve the problem. For this reason, we have designed a retractable handling power-assisted robotic arm to solve many problems of couriers, so that they can work more safely, efficiently and conveniently.
