Pole-climbing robot

Abstract

The invention discloses a pole-climbing robot. An upper elastic claw device is elastically abutted against two sides of a driven cam; a lower part elastic claw device is elastically abutted against a curve external edge of a driving cam; the upper part elastic claw device and the lower part elastic claw device are controlled to alternatively conduct clamping actions via changes of the sizes of the external edge of the driving and driven wheels; a displacement reference point is provided for the other elastic claw device by the alternated elastic claw device; a crank drives the upper and lower elastic claw devices to alternatively move upward to achieve stroke changes; further the driving cam is a parallel-connected cam formed by a first driving cam and a second driving cam, so a clamping period of the lower part elastic claw device is the same as a pushing period of a second crankshaft; the upper elastic claw device can be ensured to finish upward displacement; and with cooperation among the driving cam, the driven cam and the stroke changes, actions of clamping, expanding, lifting and pushing of the pole-climbing robot can be finished through only one power mechanism.

[0002] With the rapid development of the economy, there are more high-pole facilities related to commercial or municipal engineering in cities, such as street lamps, utility poles, billboard columns, etc. These facilities need to be cleaned and maintained regularly, and most of the work is done by manpower nowadays. , low efficiency, high cost, and high risk. Therefore, people have invented pole-climbing robots, which use machinery instead of manpower to perform more dangerous tasks such as climbing and high-point maintenance. The normal operation of the pole-climbing robot requires two necessary function to climb up and down on the light pole, that is, the mobile function and the attachment function

However, most of the existing pole-climbing robots use multiple braking mechanisms to separately control the rising action and the alternate jaw action, which is costly and complex in structure. In addition, there are also pole-climbing robots that only use one braking mechanism. For example, the "walking pole climbing robot" whose patent application number is 201110101717.1 uses a braking mechanism to control the two cranks to alternately rotate at an angle of 180°, so that the left climbing arm or the right climbing arm can perform continuous and uninterrupted alternation. Move up and down, and use the angle matching between the friction ejector rod and the robot body of the climbing rod, and hang the robot body of the climbing rod on the climbing object through friction, so that the climbing arm forms a self-locking on the climbing object. Although the above method only A braking mechanism is used, but the braking mechanism is only used to provide kinetic energy for the alternating up and down movement of the left climbing arm or the right climbing arm, while the climbing arm is held in position on the climbing object by friction, and There is no active clamping of the climbing object. When the friction force of the friction surface is not enough to support the weight of the pole climbing robot, it is easy to cause the pole climbing robot to fall from the climbing object and damage the pole climbing robot.
