Vibration absorbing device

Abstract

The invention discloses a vibration absorption device consisting of an installation plate (1) for upper acetabula, an installation plate (2) for lower acetabula, twelve acetabula components, a deflating component (6), an eccentric wheel, a motor (5) and an eccentric wheel frame (7); the twelve acetabula components are divided into two groups and are respectively connected with the installation plate (1) for upper acetabula and the installation plate (2) for lower acetabula through separate connecting rods; the deflating component (6) is fixed on the upper panel of the installation plate (1) for upper acetabula through the motor base (61) of a steering engine and the motor (5) is fixed on the upper panel of the installation plate (1) for upper acetabula through an installation rack (51) for motor; a base (72) of the eccentric wheel frame (7) is connected on the lower panel of the installation plate (2) for lower acetabula; a vertical slab (71) of the eccentric wheel frame (7) sequentially passes through a B square hole (207) of the installation plate (2) for lower acetabula and an A square hole (107) of the installation plate (1) for upper acetabula. The invention relates to a vibration absorption device used for a wall climbing robot, and has the adsorption principle that: by exerting vibration excitation on the acetabula, the is caused to the negative pressure is generated in the cavity of the acetabula, so as to further generate the absorption effect by applying the vibration excitation, thus achieving passive absorption of the acetabula. In the process of vibration, the positive pressure exists in the cavity of the acetabula; the bigger the vibration amplitude is, the higher the vibration frequency is and the lower the average negative pressure in the cavity of the acetabula is.

Description

technical field [0001] The invention relates to an adsorption device suitable for a wall-climbing robot, more particularly, a low power consumption, controllable adsorption device that can achieve stable adsorption on a rough surface. Background technique [0002] At present, most of the adsorption principles that can achieve stable adsorption on vertical surfaces are passive adsorption principles, that is, a vacuum pump is used to generate negative pressure in the inner cavity of the suction cup, but the passive adsorption principle can only be adsorbed on a relatively smooth surface, and on a rough surface. Then a vacuum pump with high power consumption is needed to ensure the vacuum degree in the suction cup. [0003] In the field of autonomous wall-climbing robots, in order to improve the adaptability of the robot, it is necessary to use a vacuum pump suction cup with high reliability when designing the adsorption device of the robot. Due to the large volume and high po...

Problems solved by technology

Due to the large volume and high power consumption of the vacuum pump, it is difficult for the robot to achieve complete autonomy, which limits the development of wall-climbing robot technology.
