[0002] At present, with the rapid development of my country's national economy and the need for high-yield, efficient and intensive development of coal production, mechanization of fully mechanized working faces has been widely used in large coal mines. The seals on the guide sleeves of hydraulic support columns are consumable parts. When repairing, the guide sleeves must be removed first and then the seals must be replaced. Due to the underground environment, on the one hand, the guide sleeves are rusted, and on the other hand, the support columns are large in size and weight, which brings difficulties to maintenance. The existing hydraulic support guide sleeve removal is first due to the large size and weight of the column and the limited underground space. The column must be removed manually, then hoisted and transported back to the manufacturer, and then the guide sleeves must be removed using special tools and the seals must be replaced. The labor intensity is extremely high and consumes a lot of financial, material and time resources. Whether it is labor intensity, maintenance efficiency or maintenance cost, it cannot meet the requirements of the current use of underground hydraulic supports. Therefore, a quick disassembly device for hydraulic columns for mining is needed. Utility Model Content
