1、附录河南理工大学万方科技学院本科毕业设计外文资料与中文翻译院（系部）机械与动力工程系专业名称机械设计制造及其自动化年级班级学生姓名指导教师08级机设5班周杨李延锋2012年5月15日外文资料与中文翻译外文资料：China is a mining power and mining equipment manufacture and use of mechanical and electrical power. From the 20th century, modeled after the 50s the first since the mine hoist has been designed
2、and manufactured, used more than 6,000. With the needs of the commun ity and the rapid development of technology, mining industry production equipment and facilities need to mechanizatioii, electrificatioii, The mining industry is the throat of the elevator equipment, replacement products,old produc
3、ts 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 , upgra
4、de 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 1 ini ng hoi st drum serious wear and tea
5、r, 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 cum bersome process, whi 1 e the high cost of wood 1 ining reel, high maint
6、eiionce costs, maintenance time. Consume a large amount of manpower, material and time st 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 takin
7、g into account the existing trees lining reel slot car there are many devices deficiencies, the paper lining from the existing wooden reel slot cars of the principle of analyzing devices, wear and tear on wire rope of research, the role of drum parts and the forces analysis of the existing car tank
8、equipment to improve processing methods and applications, based on the user-friendly, effective and practical under the premise of turning wood on the drum liner device was designed to maximize the improvement of steel wire rope and reel service life of wood lining and reduce production costs and sh
9、orten the processing and maintenance cycle, reducing the labor intensity. Through constsntly improving and perfecting the design of the drum lining wood turning can be a convenient device for turning wood drum liner, the installation of wire rope to reduce wear and tear, but also extended the servic
10、e life of wooden drum and the lining can produce a substantial savings cost.HKM2X4X1. 8-based transformation of hoistJiaomei jiulishan mine hoist IIKM2X4 XI. 8 Department of the former Soviet Union and type of products manufactured in the 50s, the reel structure of a typical shell thick branch. Put
11、into use since 1963 until now, has been running for 47 years, for a total of about 64 million out of coal t. With the increasing production to meet the needs of the mine production in 1982 had a greater technological innovation, the annual output from 1,200,000 t to 1, 800, 000 t. Enhance the increa

Also in 1985 inside the drum in two directions along the circumference, respectively，an incTesse of the 1-11 # 2, to increase the support drum, to try to resolve open reel reel
13、 welding and the phenomenon of skin retraction. However, after running for some time, the support drum parts and drum skin open welding, the cracks gradually serious phenomenon, there are four supported I-beam 3 has a horizontal fracture,open reel welding vice 21, all four I-beam horizontal fracture
14、. In order to ensure safety in production, we have adopted a variety of met hods, such as an increase to strengthen the board, direct welding, hit 45 groove welding, welding, after annealing, and so will not solve the problem of DC welding, but welding arising as a result of repeated stress concentr

In order to ensure safety in production, production management group and the jiulishan mining joint research, the status quo thro
