An adsorption device for a detection robot

Abstract

The invention discloses an adsorption device of a detection robot. The adsorption device comprises a robot shell, adsorption suction cups and a control main board. A negative pressure cavity is formed in the robot shell, and a negative pressure centrifugal fan is arranged at the top end inside the negative pressure cavity; and the negative pressure centrifugal fan is connected with the control main board through a wire, and the adsorption suction cups are fixedly mounted on the lower surface of the cavity. The adsorption device has the advantages that through a negative pressure system, the suction cups carry out adsorption so as to enable the robot to stay on the important detection portion for a long time, extra power is not needed, and long-time work of the robot is achieved; and in the staying process of the robot, internal adsorption pressure of the suction cups is reduced, and through a pressure load sensor in a reset device, the negative pressure centrifugal fan is opened to provide adsorption force, so that use reliability of the robot is ensured.

Description

technical field [0001] The invention relates to the technical field of an adsorption device for unmanned detection of bridge bottom fractures, in particular to an adsorption device for a detection robot. Background technique [0002] At present, the fracture detection team at the bottom of the bridge is used for manual detection, but the bottom of the bridge cannot be reached manually, so it can only be detected by using a high-magnification telescope or by setting up a scaffolding detection platform. It requires a lot of manpower and material resources, and the construction site of the platform is complicated, the construction is difficult, the inspection workload is large, the work efficiency is low, and there are potential safety hazards when manually walking on the inspection platform. The current patent name is a negative pressure adsorption for bridge crack detection. The climbing robot, application number: 201310143474.7, uses the rubber sealing skirt and negative pre...

Problems solved by technology

[0002] At present, if the bridge bottom fracture detection team detects manually, but the bridge bottom cannot be reached manually, so it can only be detected by using high-magnification telescopes or by setting up scaffolding detection platforms. High-magnification telescopes are easy to miss small cracks when detecting small cracks. The detection platform is set up. It requires a lot of manpower and material resources, and the construction site of the platform is complicated, the construction is difficult, the inspection workload is heavy, and the work efficiency is low. There are safety hazards in manually walking on the inspection platform. The current patent name is a negative pressure adsorption for detecting bridge cracks. Climbing robot, application number: 201310143474.7, uses rubber sealing skirt and negative pressure technology to realize the adsorption between the detection robot and the wall at the bottom of the bridge. It cannot stay in the key detection parts for a long time, and the work consumes a lot of energy.
