Description

Technical Field

[0001] The invention relates to the technical field of maintenance tools, and in particular to a quick-installation chimney maintenance tool. Background Art

[0002] Chemical tests, special tests and other processes produce toxic and harmful gases. Although this part of the exhaust gas has been treated, a small amount of toxic and harmful substances still remain. For the treated gas, the test site usually uses a high chimney for emission, and the height of the chimney can generally reach more than 100 meters to reduce the impact on the test site and the surrounding environment. The chimney structure is generally a thick bottom and a thin top structure, usually with a top diameter of 4-5 meters, a bottom diameter of 10-12 meters, and a height of more than 100 meters. After the anti-corrosion materials inside the chimney are used for a certain period of time, they will be damaged, peeled off, and further corroded the inner wall of the chimney. Therefore, the chimney is generally maintained once every 1-2 years. The traditional chimney maintenance method uses a basket or a "flying man", but this method has the following disadvantages: 1. The maintenance range cannot cover the entire chimney, and there are dead corners for chimney maintenance; 2. The personnel spend a long time in the chimney for maintenance, and the toxic and harmful substances remaining on the inner wall of the chimney increase the risk of personal injury. Summary of the invention
