Caterpillar band and sucker combined type traveling device for wall-climbing robot

Abstract

The invention discloses a caterpillar band and sucker combined type traveling device for a wall-climbing robot, and belongs to the technical field of wall-climbing robots. The caterpillar band and sucker combined type traveling device for the wall-climbing robot comprises rear wheels, a caterpillar band, auxiliary wheels, a torsion bar hanging mechanism and front wheels, wherein the caterpillar band is arranged between the rear wheels and the front wheels; a plurality of suckers are distributed on the surface of the outer side of the caterpillar band; the torsion bar hanging mechanism is arranged on the inner side of the caterpillar band; one end of the torsion bar hanging mechanism is hinged to a chassis of the wall-climbing robot; the other end of the torsion bar hanging mechanism is hinged to the auxiliary wheels; the auxiliary wheels are meshed with the inner side of the caterpillar band; and areas, which correspond to the auxiliary wheels, of the surface of the inner side of the caterpillar band are magnetic force action areas. The suckers can be reliably absorbed on a wall surface without an independent vacuum source or a controller; when the caterpillar band and sucker combined type traveling device moves, movement impact and driving loss can be effectively reduced; and the caterpillar band and sucker combined type traveling device is simple in structure and low in cost.

Description

technical field [0001] The invention relates to a walking device of a wall-climbing robot, more specifically, to a crawler-suction-cup combined walking device for a wall-climbing robot. Background technique [0002] When we make a glass curtain wall cleaning robot, we need a vacuum suction cup to make the cleaning robot attach to the glass curtain wall and move freely. The existing vacuum suction cups need to be connected with a vacuum generator and multiple electromagnetic control valves to control the vacuum suction cup. The connection of the vacuum source has a complex structure. Generally, in order to enable the cleaning robot to walk on complex exterior walls, multiple vacuum suction cups are mostly used to form a suction cup array. At this time, the weakness of the public vacuum source is exposed. In the bonding gap, the suction cups in the suction cup array are not tightly sealed, causing the vacuum degree of the public vacuum source to drop and affecting the use. I...
