JHB-8型柱绞车的设计.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，同时也可用于上山、下山、平巷等综采工作面设备的搬迁，比如液压支架、溜槽等。此外，拉紧皮带机机头、运料、调度车辆等工作都可以用这种绞车来完成。在港口、码头、建筑工地、工厂企业，这种绞车也可以发挥作用。 JHB—8型回柱绞车的传动系统采用两级传动，包括蜗轮蜗杆齿轮传动、圆柱齿轮传动，在设计过程中采用承载能力大的圆弧蜗轮蜗杆；而且采用了开式齿轮传动，大大简化了机械部分的传动系统，便于安装和拆卸，结构布置紧凑、合理。 在设计过程采用锥面制动端盖实现了工作状态和制动状态的互锁。绞车起动时动载小，钢丝绳受到的冲击小。只需轻轻点动电机控制按钮，就可起动电机，然后操作制动的手柄，便可实现绞车的动作。 设计中为使回柱绞车具有良好的防爆性能采用了防爆电动机以及防爆磁力启动器和防爆按钮开关。该绞车适用条件强、使用寿命长。该绞车结构紧凑，外形尺寸小；结构为近似对称布置，外形美观，成长条形，底座呈雪橇状；绞车重心低，底座刚性好，可安装地锚，运转平稳，安全可靠，安装方便。 关键词：回柱绞车； 圆弧蜗轮蜗杆； 制动 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
