Magnetic Wall Climbing Inspection Robot

1Magnetic Wall Climbing Inspection RobotInstructions

At present, a large amount of on-site solution experience has been accumulated in many fields such as petrochemicals, boiler special inspection, and electricity. Equipped with electromagnetic ultrasound, it can efficiently detect various storage tanks, containers, etc. In addition, it can perform spot checks or B-scan thickness measurements on areas with severe corrosion and erosion, especially at the bottom, bends, or tees of pipelines. The magnetic suction wheel is attached to the magnetic metal surface by a strong magnetic permanent magnet, so even in the event of an unexpected power outage, there is no risk of the vehicle falling off the tested surface. It can safely perform scanning work in different postures such as horizontal, vertical, and inverted. The vertical load is 5kg, and dragging a 5kg heavy object does not affect its various movements in the vertical direction.

4、 Technical features

1. The magnetic suction wheel tightly adheres to it

(1) Magnetic suction wheels are attracted to magnetic metal surfaces by strong permanent magnets, which have very high adhesion and can firmly adhere to vertical, inclined, or inverted surfaces. This enables robots to move stably in various complex environments.

(2) Magnetic suction wheels have a wide range of applications and can operate on various forms of magnetic metal surfaces, suitable for different working environments. Whether it is a smooth surface, rough surface, or curved surface, the magnetic wheel can adapt and provide reliable motion performance.

(3) Due to the lack of a complex mechanical structure, the magnetic wheel system is relatively easy to operate and maintain. Magnetic suction wheels are usually maintained by keeping the magnetic system clean and upkeep, which is relatively easy to implement.

2. Data processing and transmission capability

(1) A video remote transmission system is a system that uses wireless or network signals to transmit video data from one location to another. The video remote transmission system transmits the video signal to the remote control end through a 2.4G signal. Long transmission distance and stable transmission.

(2) A remote control terminal is a device that can be connected to a central control machine through a communication channel, used for remote control of robots. It can control and detect robots in real time, display robot detection data, and provide data export and upload functions.

(3) The data control and transmission system is used to control robots and data transmission (image, detection, control data). It has the characteristics of efficient transmission, simple and easy to use, safe and reliable, and worry free operation and maintenance.

3. Electromagnetic ultrasonic thickness measurement technology

The advantages of a wall climbing robot equipped with a new type of probe using electromagnetic ultrasonic measurement technology are:

(1) Non contact measurement: Electromagnetic ultrasonic thickness measurement technology does not require physical contact with the measured object and measures through the principle of electromagnetic induction. This means that there is no need to damage or destroy the object being tested, and it can be applied to various surface states such as roughness, corrosion, high temperature, etc.

(2) High precision and accuracy: Electromagnetic ultrasonic thickness measurement technology uses high-frequency pulse ultrasonic waves, which can achieve high-precision and accurate measurements. It can detect very small thickness changes and provide accurate thickness measurement results.

(3) Wide measurement range: Electromagnetic ultrasonic thickness measurement technology is suitable for a wide measurement range, ranging from a few micrometers to several centimeters. It can meet the measurement needs of different materials and structures, including metals, plastics, rubber, etc.

(4) Real time measurement: Electromagnetic ultrasonic thickness measurement technology can measure in real-time and provide results almost immediately. This rapid response gives it an advantage in applications that require immediate feedback and real-time monitoring.
