Wall climbing robot for external wall corners

Abstract

The invention relates to a wall climbing robot for external wall corners. The wall climbing robot comprises a fuselage portion and an empennage portion. The fuselage portion comprises a fixing plate, the fixing plate directly faces exposed corner lines of the external wall corner, two brackets are respectively connected with the left side and the right side of the fixing plate, motor foot stands are fixed onto the brackets, a motor is mounted on each motor foot stand, a driving wheel is connected with an output shaft of each motor, an included angle between the brackets on the left side and the right side of the fixing plate is smaller than each external wall corner, the driving wheels are tangential to wall surfaces of the external wall corners, and acute angles are formed between the obliquely downward axes of the driving wheels and the exposed corner lines of the external wall corners; the empennage portion comprises an empennage, the upper end of the empennage is fixedly connected with the fixing plate, two small empennage foot stands are respectively connected with two ends of the lower end of the empennage, a driven wheel is mounted on each small empennage foot stand by the aid of a bearing, the driven wheels are tangential to the wall surfaces of the external wall corners, and axes of the driven wheels are perpendicular to the exposed corner lines of the external wall corners. According to the scheme, the wall climbing robot has the advantage that problems of high material and equipment requirements, low energy utilization rate, insufficient load capacity and the like of existing wall climbing robots can be solved.

Description

Technical field [0001] The invention relates to a wall-climbing robot, in particular to a wall-climbing robot at an exterior wall corner. Background technique [0002] With the further advancement of my country's industrialization and modernization, higher requirements have been put forward for firefighting and disaster relief, military reconnaissance, expedition rescue, and aerospace. Existing wall-climbing robots can be roughly divided into: vacuum suction cup-type wall-climbing robot, wind pressure-type wall-climbing robot, and viscose-type wall-climbing robot. Vacuum suction cup wall-climbing robots can be roughly divided into two types: one is a bionic legged hydraulic suction cup robot, which requires a more powerful hydraulic machine, and each gait movement needs to partially release the suction cup pressure, resulting in energy utilization It is not high and the climbing efficiency is low; the other is a fan-pumped vacuum suction cup wall climbing robot, which has extrem...
