JHB-8型回柱绞车的设计.doc

　　　 摘 要 JHB—8型回柱绞车是一种有效的矿山辅助运搬设备。该型绞车主要应用于回柱放顶之用ABSTRACT JHB—8 to prop pulling winch is an effective mine auxiliary equipment shipped to move. This type of winch mainly used to top-of-use, but also can be used to uphill, downhill, Pingxiang fully mechanized coal face, such as the relocation of equipment, such as hydraulic support, the chute, and so on. In addition, the belt-tighten the nose, and transport material, scheduling and other work vehicles can be used to complete the winch. At ports, terminals, construction sites, factories and enterprises, the winch can also play a role. JHB—8 to prop pulling winch—drive system using two transmission, including worm worm gear drive, cylindrical gear transmission, in the process of designing a large carrying capacity of the arc Worm Gear, and adopted the open-gear transmission, greatly simplifies the Mechanical part of the drive system, easy to install and demolition, structural layout compact and reasonable. In the design process using cone brake cover state and work to achieve a state of interlocking brake. Starting at the winch dynamic small, the impact on the rope. Just gently move the motor control button, we can start the electrical and operation of the brake handle, can be realized winch action. Design for the prop pulling winch has a good performance by the explosion-proof electrical explosion-proof and explosion-proof magnetic starter button switch. The winch conditions apply strong and long life. The winch compact structure, shape, small size, structure similar to symmetrical layout, aesthetic appearance, growth Strip, a sled-shaped base; winch low center of gravity, rigid base, and can be installed to anchor, a smooth operation, safety and reliability, ease of installation.
