Description

technical field [0001] The invention belongs to the technical field of online detection of industrial tower equipment, in particular to a scanning mobile device for tower fault detection. Background technique [0002] Tower scanning technology is an internal fault detection technology for online tower equipment that has no impact on the environment and equipment. It can intuitively reflect the gas-liquid distribution status and solid parts inside the tower equipment, and realize the invisible faults inside the tower equipment. Online detection shortens the maintenance cycle and reduces the cost of fault diagnosis.

Problems solved by technology

[0003] The most important part of the tower scanning technology is to obtain accurate detection data and analyze the data. To obtain accurate detection data, it is necessary to move the detector and the ray output device synchronously from the top to the bottom of the tower on the spot to obtain one or more Therefore, to obtain accurate detection data, it is necessary to ensure the synchronous movement of the detector and the ray output device. At present, the scanning mobile devices used in the tower scanning technology all adopt the method of tape pulling to ensure synchronous movement, but the tape pulling The method has the following disadvantages: 1. The length of the tape measure is limited, and it must be measured in two sections for super high towers, which will inevitably cause large errors; 2. The tape measure is mostly made of cloth with certain flexibility, which will also cause measurement errors; 3. The tape measure has a wide cross-section, which will cause great wind resistance. When working at heights, the wind will cause the detector and the ray output device to swing in all directions, which has a great impact on the measurement; 4. When using a tape measure for traction, the tape measure is light and thin There is no self-locking device, the operator must always hold the tape with both hands, which consumes a lot of energy, and three people are required to operate two tapes and the data acquisition device respectively, which is a great waste of manpower, etc.

Therefore, the cost of obtaining data by means of tape measure is very high and it is difficult to obtain excellent detection data
