An inspection robot telescopic arm

Abstract

The invention provides a telescoping arm of a patrol robot. The telescoping arm comprises a drive module, a telescoping arm body and a slide arm, wherein the telescoping arm body comprises a guide rail, a belt and a belt clamp; front and rear ends of the guide rail are respectively provided with a front wheel and a rear wheel; the belt is wound on the front wheel and the rear wheel; the belt clamp clamps the belt; the guide rail is connected with the drive module; and the slide arm is movably mounted on the guide rail and is connected with the belt. The telescoping arm utilizes the drive module to drive the telescoping arm body and the slide arm to move; when the telescoping arm body moves, clamping friction force of the belt clamp on the belt is overcome, so that the belt rotates, and the belt rotates to drive the slide arm to move, and therefore, telescoping of the robot arm is realized.

Description

technical field

[0001] The invention belongs to the technical field of robots and relates to a telescopic arm of an inspection robot. Background technique

[0002] When an inspection robot performs inspections, its fuselage cannot accurately reach all positions, especially for some robots whose fuselage can only expand and contract in the next dimension. When the detection target has a certain distance from its detection sensor, it needs to The sensor can move back and forth to improve the working precision, and the arm disclosed by the invention is applicable to such application occasions.

[0003] Chinese invention patent document CN101780674A "Transmission line automatic inspection robot telescopic arm transmission device" discloses a robot telescopic arm transmission device in the form of an inner and outer lifting cylinder similar to an antenna, and the arm lifting mechanism consists of an inner and outer screw rod and a nut transmission mechanism , inner and outer lif...
