Title:
WALL SURFACE TRAVELING ROBOT
Document Type and Number:
Japanese Patent JP2011194937
Kind Code:
A
Abstract:

To provide a wall surface traveling robot stably sucked to wall by improving a traveling property under adverse circumstances of the wall surface traveling robot sucked on outer or inner walls of various large structures and engaging in various operations, and by reducing a weight of the wall surface traveling robot itself and giving a lift force.

This wall surface traveling robot comprises a chassis 1 having a drive wheel 7 at an apex of a triangle frame; a suction part 2 having a brush skirt 4, in which brush bristles 12 with a length long enough to contact of a wall W of a working object are tightly aligned around a suction plate 3 parallel to the wall W; a suction mechanism, in which a bell mouth 6 opened at a center of the suction plate is connected to a sucking duct fan 5; a traveling drive mechanism in which a stud 7b stands on the drive wheel in a radial direction to provide a steering function and a differential drive function not to cause slippage to the wall W during steering; and a duct fan 8 for generating a lift force and/or a lift force device for reducing an empty weight amount made of a helium gas air sac giving a buoyancy, so that a mission equipment 11 can be mounted and held.
