With the needs of the community and the rapid development of technology,mining industry production equipment and facilities need to mechanization,electrification,The mining industry is the throat of the elevator equipment,replacement products,old products long time run,the structural problems behind the original exposed prominent fault more serious impact on the safety of mining operations,curb the rapid development of mining industries to the national economy with to the adverse effects.With the ever-changing mine to increase production ,upgrade the machine to improve safety,of machine to run automated,reducing operation and maintenance of the labor intensity,the speed of of the accident and so on,into the urgent requirement.Mine hoist for renovation,is extremely important. For example,wood lining hoist drum serious wear and tear,when the trees lining up to a certain degree of wear and tear on the lining must be replaced wooden reel,or a security incident is likely to affect the safety in production.And replacement of wooden drum liner is a very cumbersome process,while the high cost of wood lining reel,high maintenance costs, maintenance time.Consume a large amount of manpower,material and time at the same time,and affects the security of the entire mine production and demand for production,to that end, the design of a reel turning wood lining device is a very necessary technology.As a result of taking into account the existing trees lining reel slot car there are many devices deficiencies,the paper lining from the
