| With the continuous increase of mining depth and annual output, multi ropefriction hoisting machine application in the mine more widely. Winding hoist machinecompared to the previous, friction hoist overcome bulky volume, manufacturing,transportation, installation inconvenience, has compact layout area, convenientdisassembly and transportation, large lifting capacity, high stability and otheradvantages. Nearly20years of development has become the main force of minehoisting equipment. Friction hoist to rely on the leading wheel friction pad and thewire rope friction drive to see, to realize the lifting task. Therefore, the frictionbetween the friction pad and the wire rope is big enough, if the friction is not enough,it will have a slide, which will be directly related to the friction lift ability and thereliability improvement process, this article mainly aims at the pottery two minershoist antiskid reliability analysis.First introduces the structure and working principle of multi rope frictionhoisting machine. Based on the multi rope friction hoist structure and workingprinciple is introduced, the explicit multi rope friction hoisting machine in normaloperation nonskid condition, in order to research.Followed by the development of a general scheme of analysis of multi ropefriction hoist machine antiskid reliability, by the friction force between friction padand the wire rope as a starting point, considering the effect of Tao two mineenvironment and the scene of the running state of the main shaft hoisting machineantiskid safety performance, the regression analysis method, regression equationobtains the correlation factor closer to actual the.Finally, the multi rope friction under the running state of income of antiskidsafety analysis of hoist, compared the results obtained antiskid checking calculationmethod of lectotype design with Tao two mine currently in use, get more canguarantee the reliable operation of the hoisting machine checking method. |
