    Design of JTK mine hoist

    Abstract

    Because of its good performance and high reliability, mine hoist has become one of the fixed equipment of mining machinery equipment in our country. As an effective lifting mechanism,mine hoist is responsible for the connection of underground mining and the lifting of the ground operations.Winch is a central hub in the process of coal mining. Because of the important role of the winch, the safety of its structure has a great impact on the efficiency  of mine operations and the safety of staff. Therefore, rigorous structural design is the  key to improve the overall performance of the winch.

    This paper briefly summarizes the development situation of mine hoist at home and abroad in recent decades, and summarizes the existing problems of mine winch, and finds out the key to improve the structure performance of the winch. After introducing the basic structure and the working principle of winch.On the basis of the original design data, type the selection of the design of motor, clutch, and secondary cylindrical gear reducer device parameters, design of the structure of the drum and a wire rope selection, reel spindle design. On the structure performance to meet the requirements of the foundation, reducer gear, levels of transmission shaft, roller bearing and linkages were bending and torsion strength check and the service life of the budget. Through the final assembly to ensure that the design of the theory can be implemented, so as to complete the overall design of mine hoist.

    This paper has 8 figures, 4 tables and 43 references.

    Key words: mining machinery; hoist; two stage reducer; structure design
