摘 要 煤炭被人们誉为黑色的金子，工业的食粮，它是十八世纪以来人类世界使用的主要能源之一。在矿井系统中，提升机是不可或缺的主要设备之一，而保障矿井提升机的安全运作更是煤矿生产的重中之重。针对矿用罐笼门原理和结构上的弊端，目前，一种基于无极绳的自动罐笼门应运而生。该设备是由PLC通过对外部动力机制和无极绳牵引的控制，达到在提升过程中的安全闭锁。该系统具有简单的结构，灵活、可靠的操作和高度的自动化。此外，该设备安全，结构紧凑，适合广泛的应用。 作为一个多用途笼吊提升装置，罐笼不仅能提升人员、各类用于地下的机械和电气设备，也可以转移在矿井提升系统的材料和矿物质。在特殊时间提升人员时，必须确保人身安全，所以提升罐笼的出入口必须安装安全的罐笼，要求是安全、可靠和易于使用。虽然罐笼的结构经历了数次改善，罐笼的设计理念依旧保持强调安全性，其舒适性和用户满意度都被忽略。为了保障其安全性和舒适性，同时提高自动化程度，减少体力劳动强度，一种基于无极绳的新型自动罐笼门应运而生。 基于无极绳的自动罐笼门结构的设备是在PLC对外部动力交换机的核心和无极绳运动的整体程序控制基础上进行的闭环传递，从而达到罐笼门在提升过程中安全封锁的目的。 关键词：无极绳； 罐笼门； 可编程逻辑控制器。 ABSTRACT The coal was hailed as the black gold, food industry, it is one of the main energy of the human world in the 18th century. Mine system, the elevator is one of the indispensable equipment, to protect the mine to enhance the safe operation of the machine is a top priority of mine production.Aiming at the disadvantages of cage door’s principle and structure used in mine， at present, a type of automatic cage door based on endless rope is designed. The equipment is controlled by PLC with mechanism of external motive force switch and traction by endless rope, which achieves safe blocking in the hoisting process of cage door. The system has simple structure, flexible and reliable operation and high degree of automation. In addition, the equipment is also safe, shapely and comfortable with a wide range of practical. As a multi-purpose cage hoisting container, the cage not only can hoist personnel, various types of mechanical and electrical equipment for use underground, but also can transfer materials and minerals in mine shaft hoisting system. When lifting personnel in particular must ensure the personal safety, so the safety cage must be installed for lifting cage’s entrances and exits, the request is safe, reliable and easy to use. Although the cage of the structure has experienced several improvements, the cage’s design concept is keeping emphasizing the safety, and its comfort and user-friendly are ignore
