Strong magnetic wheel type adsorption climbing robot platform for nondestructive testing of tower body of wind driven generator

Abstract

The invention belongs to the technical field of nondestructive testing devices, and particularly relates to a strong magnetic wheel type adsorption climbing robot platform for nondestructive testing of a tower body of a wind driven generator. The strong magnetic wheel type adsorption climbing robot platform for nondestructive testing of the tower body of the wind driven generator comprises a gear box, an upper connecting plate, a lower connecting plate, a motor component, a five-wheel synchronous transmission wheel system and a neodymium iron boron strong magnetic wheel. The platform can improve the detection efficiency and precision, and avoids the falling danger of manual high-altitude detection operation. A left-right 180-degree reverse symmetric compact modular design is adopted, and a front wheel and a rear wheel on the same side are synchronously driven; the neodymium-iron-boron strong magnetic wheel is innovatively designed, and the vertical load of the robot platform on the vertical iron surface can meet the technical requirements of carrying any nondestructive testing probe and equipment; gears of a transmission path from the motor to the two wheels on each side adopt five-wheel same-speed synchronous transmission design; climbing operation can be carried out on a detected surface of a large-angle or even vertical wind driven generator tower body, and meanwhile stable reliability is achieved.

Description

technical field [0001] The invention belongs to the technical field of non-destructive testing devices, in particular to a strong magnetic wheel adsorption climbing robot platform for non-destructive testing of wind power generator towers. Background technique [0002] Wind energy is currently one of the important sustainable energy sources that countries around the world focus on and compete to utilize. my country has vast areas rich in wind energy such as plateaus, hills and coastlines, coupled with the government's subsidy policy for the purchase of wind power equipment, my country's wind power industry has ushered in rapid development. In 2010, the total capacity of wind power generators in China reached the first place in the world, and it is expected to reach 210 million kilowatts in 2022, when the number of wind power generators in my country will reach hundreds of thousands. With the development trend of large-scale wind turbines, the overall height of wind turbines...

Problems solved by technology

① The ground observation method is a simple and easy-to-operate detection method that is often used. The staff stand near the tower body and borrow eyesight or telescopes to observe whether there are cracks or deformations on the surface of the tower body. The accuracy and precision of this method are relatively high. Difference

② UAV inspection has recently developed relatively rapidly. The UAV is equipped with a high-definition camera and flies to the vicinity of the tower body, and uses the sweeping method to conduct safety inspections on the surface of the tower body. This detection method has a relatively high detection accuracy for surface cracks, but No ability to identify early micro-cracks inside the material

The lateral size of the robot platform is too large, and crawling on the surface of the tower body with a certain curvature will cause the surface effect to be too obvious, and the contact area between the wheels and the tower body will be reduced, which will reduce the load capacity and working reliability of the robot platform.

Another disadvantage of the excessively large lateral size of the robot platform is that the space between the robot platform chassis and the detected surface of the tower body is too small, which may easily cause the robot platform to drag the bottom

[0009] At present, there is no relevant automatic detection robot platform in this field. How to solve the above technical problems, so as to realize the original design of the automatic detection robot platform, is an important topic in front of the applicant.
