速差防坠器性能测试系统设计

摘 要

防坠落的系统分为：垂直生命系统与水平生命系统。水平生命系统用的比较广泛。速差防坠器是这个系统的一部分，它能在限定距离内快速制动锁定坠落物体 ，适合于货物吊装，保护地面操作人员的生命安全和被吊工件物体的损坏 。适用于天车起吊时防止被吊工件意外坠落时的安全防护，能有效地保护地面操作人员的生命安全和被吊工件物体的损坏，应用于冶金汽车制造，石油化工、工程建设、电力、船舶、通讯、制药、桥梁等高处作业场所。

速差防坠器利用物体下坠速度差进行自控，高挂低用。在使用半径内，不需更换悬挂点。正常使用时，安全绳将随人体自由伸缩。在器内机构作用下，处半紧张状态，使操作人员无牵挂感。万一失足坠落，安全绳拉出速度明显加快，器内锁止系统即自动锁止。使安全绳拉出距离不超过0.6米，冲击力小于人体可承受的极限，对失足人员毫无伤害。负荷解除即自动恢复工作。工作完毕安全绳将自动回收到器内，便于携带。目前速查防坠器国内厂家生产的产品质量低、可靠性差，且核心部件难以摆脱对外资产品的依赖。速差防坠器的研制过程中，非常重要的就是可靠性的测试，因此如何搭建以速差防坠器为核心的生命支持系统，并测试其性能，以促进防坠落系统的优化升级非常重要。

Design and experiment of performance Test system for Speed differential Anti-fall device

ABSTRACT

The anti-fall system is divided into vertical life system and horizontal life system. Horizontal life systems are widely used. As a part of this system, the speed differential anti-fall device can lock a falling object quickly within a limited distance. It is suitable for cargo hoisting, protecting the life of ground operators and the damage of suspended workpiece objects. It can effectively protect the life of the ground operator and the damage of the suspended workpiece. It can be used in the manufacture of metallurgical automobile, petrochemical industry, engineering construction, electric power, etc. It is suitable for the safety protection of the suspended workpieces during the lifting of the crane, and can effectively protect the life safety of the ground operators and the damage of the suspended workpiece objects. Ships, communications, pharmaceuticals, bridges and other high-level working places.

The speed differential anti-fall device uses the falling speed difference of the object for automatic control, high hanging and low use. There is no need to replace the suspension point within the radius of use. When used normally, the safety rope will stretch freely with the human body. In the role of in-device mechanism, in a semi-tense state, so that operators do not have a sense of concern. In case of failure to fall, safety rope pull-out speed is significantly accelerated, the in-device locking system is automatically locked. The safety rope is not more than 0.6 meters away, the impact force is less than the limit that the human body can bear, and does no harm to the missing person. When the load is relieved, the work will be resumed automatically. After work safety rope will be automatically recovered into the device, easy to carry. At present, the domestic manufacturers of the quick inspection anti-fall device produce The quality of the products is low, the reliability is poor, and the core components are difficult to get rid of the dependence on foreign products. It is very important to test the reliability of the speed differential anti-fall device. Therefore, it is very important to build the life support system with the speed difference anti-fall device as the core and test its performance in order to promote the optimization and upgrade of the anti-fall system.
