一种皮带传动式压绳装置 Belt drive type rope device
技术领域 Technical field
本发明涉及一种绳索缓降装置， 尤其涉及一种绳索缓降器的压绳装置。 背景技术 The invention relates to a rope descending device, in particular to a rope lowering device for a rope descending device. Background technique
在日常生活或工作中， 人们经常会在高处遇到危险， 如果没有其它方法可以逃生时， 需要借助空中降 落装置逃生， 公知的空中降落装置包括摩擦限速式、 手动制动限速式和液压阻尼限速式， 前两者缺点是可 靠性差， 最后者结构比较简单， 性能也比较可靠， CN87216143公开一种用活塞和凸轮起限速作用的空中降 落装置， 但凸轮只承受压力， 不承受拉说力， 在降落过程中存在限速不均匀； ZL2003101127389 和 ZL2003201232361分别公开了一种采用曲轴与液压调速式控制器相连接的原理， 但由于采用链梯， 降落高 度受限制； ZL2007202016917公开一种液压限速式空中降落器， 其结构是过绳式的， 过绳式结构的绳索缓 书 In daily life or work, people often encounter dangers at high altitudes. If there is no other way to escape, they need to escape by means of aerial landing gear. The known airborne landing gears include friction speed limit, manual brake speed limit and The hydraulic damping speed limit type, the first two disadvantages are poor reliability, the last structure is relatively simple, and the performance is relatively reliable. CN87216143 discloses an air landing device that uses a piston and a cam to speed limit, but the cam only bears pressure and does not bear Pulling force, there is uneven speed limit during the landing; ZL2003101127389 and ZL2003201232361 respectively disclose a principle of connecting the crankshaft with the hydraulic speed control controller, but due to the use of the chain ladder, the landing height is limited; ZL2007202016917 discloses one Hydraulic speed limit type airborne gearer, whose structure is over-the-rope, rope-type structure
降器一个关键问题是如何确保绳索与绕绳轮之间有足够摩擦力。 为了增加绳索与绕绳轮之间的摩擦力， 其 公开了一种压绳装置，即是增加上压绳轮和下压绳轮， 但上压绳轮没有起到增加绳索与绕绳轮之间的压力 和摩擦力的作用， 下压绳轮虽然起到一定的增加绳索与绕绳轮之间的压力和摩擦力的作用， 但由于下压绳 轮是设置在一个吊臂上且重力件是直接与吊臂连接， 因此吊臂必须安装在绕绳轮的下侧， 绳索从受力端到 压绳点的所绕过的角度只有半个圆周的角度， 因此， 起到的压绳效果并不是很好； 本文中， 绳索从受力端 到压绳点的所绕过的角度称之为压绳包角。 A key issue with the drop is how to ensure sufficient friction between the rope and the reel. In order to increase the friction between the rope and the reel, it discloses a pressure rope device, that is, an upper pressure rope and a lower rope pulley, but the upper pressure rope does not serve to increase the rope and the rope pulley. The pressure and friction between the lower pressure sheaves play a certain role in increasing the pressure and friction between the rope and the sheave, but because the lower pressure sheave is placed on a boom and the gravity member It is directly connected to the boom, so the boom must be installed on the lower side of the rope wheel. The angle of the rope from the force end to the pressure rope point is only half a circle angle. Therefore, the rope effect is achieved. Not very good; in this paper, the angle that the rope is wound from the force end to the pressure rope point is called the pressure rope wrap angle.
