摘 要:石油钻机刹车系统机构是绞车的关键部件，针对使用钻机带式刹车系统带来的许多安全问题，设计制动系统工作可靠且具有良好的工艺特性的盘式刹车系统。盘式刹车系统主要有刹车盘、钳架，刹车块，制动钳、钳臂、液压控制系统组成，制动钳则由油缸、活塞、调节螺母、弹簧等主要零件构成,工作原理为油口进油刹车松开，卸油压刹车，刹车大小由刹把调节刹车阀来改变油缸压大小来实现，从而提高刹车力，增强刹车系统的可靠性和安全性。  

   论文开头介绍了设计此绞车的目的和意义，绞车的发展、研究现状以及绞

车的发展趋势，再对绞车的参数进行设计计算，主要有滚筒的直径、缠绳层数、滚筒缠绳的平均直径，以及绞车游动系统的分析。之后进行绞车结构设计，包括钳架结构，液压缸的结构和刹车钳的结构等。再对绞车的零部件进行了强度校核，保证其满足强度要求。

ABSTRACT:Drilling rig brake system mechanism is a key part of hoist, many security problems according to use drilling with brake system, disc brake system design process characteristics is reliable and has good braking system. Disc brake system mainly has the brake disc, clamp frame, brake block, brake clamp, the clamp arm, hydraulic control system, brake clamp is composed of the main parts of cylinder, piston, a regulating nut, spring, the working principle for the oil into the oil unloading hydraulic brake, brake release, brake size by brake adjusting brake valve to change the cylinder pressure is realized, thereby improving the braking force, enhance the reliability and safety of the brake system.

  This paper first introduces the purpose and significance of the research design of the winch, winch, the development present situation as well as the cutter Development tendency of car, and parameters to the winch design calculations, mainly has the diameter of the drum, drum rope layer, the average diameter of rope wrapped around, as well as the analysis of traveling system of the winch. After the winch structure design, including the clamp frame structure, hydraulic cylinder structure and the brake clamp structure. Parts of the winch of strength check, to ensure that they meet the strength requirements.
