[0002] The mine shaft tower skip shaft adopts skip hoisting, which is usually pulled by several hoisting wire ropes and fixed by tank ropes (stabilizing tank ropes) to lift ore back and forth in the shaft. Taking a mining company in Yunnan as an example, the maximum hoisting speed of the skip is 12.7m / s, and the system hoisting capacity is 7000t / d. Due to the need for operation, maintenance and overhaul of the hoisting system equipment, the skip is regularly or irregularly overhauled. During overhaul, the existing technology is that the maintenance personnel use I-beams and wooden boards to build an overhaul platform at the shaft mouth. Each time the platform is built, the operation time is long. It takes about 8 hours to build a platform, and it takes another 4 hours to recycle the platform. The number of shutdowns for overhaul is frequent every month, which directly affects the production of the enterprise. In addition, this simple overhaul platform has the problem of poor sealing effect, and the long-term construction operation at the shaft mouth has a high safety risk. For this reason, it is very necessary to develop a quick overhaul platform for the mine shaft tower skip shaft that can solve the above problems. Utility Model Content
