纵轴式掘进机总体方案设计与液压系统设计

Roadheader is the foundation of the Coal Industry. In the coal industry, Roadheader is in the key foundation status. This paper attempts to combine industry standards and design specifications, in accordance with the requirements and design of general purpose, make general design of longitudinal roadheader and design of hydraulic system, determined to meet the requirements of the overall tunneling machine parameters. In the design of the hydraulic system, this paper basically establishes the principle of the use of hydraulic components and parameters. Here analysis of the cutting unit, operating agencies, shipping agencies, transport planes, and other intermediate load analysis. The set of Motor part include: the motor of star ferry carrying, the drive motor running, the middle of the drive motor and other transport planes. Part of the fuel tanks identified: the fuel tank movements, rotary fuel tank, the fuel tank of stretching, walking track the take-up fuel tanks, shovel board or give the Department of the calculation of the fuel tank design. Cylinder part of the structural design, the paper discusses a telescopic design of the fuel tank of the bodies, parts and drawing plans. Also had a pumping station and determine the parameters of the hydraulic system, hydraulic system performance assessment. Finally, roadheader through analysis and stability analysis is discussed.
