电梯是现今社会最常用的运载工具之一,其安全性能要求很高。一旦发生坠落或冲顶时,制动器是第一道安全防线,所以制动器制动性能的好坏,直接影响一台电梯整机安全性能。而电梯抱闸是电梯制动器上动作最频繁的安装装置,其磨耗程度直接影响制动力的大小。一般主要是在定期检查过程中进行制动抱闸试验。在不影响曳引机运转的情况下,制动器制动轮与闸瓦间隙平均值越小越好。GB/T13435-92中第5.3.16条规定:制动轮与闸瓦间隙平均值不超过0.7mm,所以对电梯抱闸磨耗进行实时监测显得十分必要。Elevators are one of the most commonly used means of transportation in today's society, and their safety performance requirements are very high. In the event of a fall or rush to the top, the brake is the first line of safety defense, so the braking performance of the brake directly affects the safety performance of an elevator. The elevator brake is the most frequent installation device on the elevator brake, and its wear degree directly affects the braking force. Generally, the brake test is mainly carried out during the regular inspection process. In the case of not affecting the operation of the traction machine, the smaller the average value of the gap between the brake wheel and the brake shoe, the better. Article 5.3.16 of GB/T13435-92 stipulates that the average value of the gap between the brake wheel and the brake shoe does not exceed 0.7mm, so it is very necessary to monitor the wear of the elevator brake in real time.
目前通过人工定期检查抱闸磨耗情况不仅费时费工,而且可能存在人为因素造成的疏漏。At present, it is not only time-consuming and labor-intensive to regularly check the wear of the brakes manually, but also there may be omissions caused by human factors.
申请号为201510695385.2,名称为一种电梯抱闸磨耗监测的方法的专利申请,公开了一种自动监测电梯磨耗的方法,主要是通过在电梯抱闸装置上接入显示控制盒、拉线位移传感器及载有相应运算程序的芯片进行监控磨耗,对零部件灵敏性要求较高,一旦灵敏性受到干扰或减弱,会造成整个报警、监控系统的失效,另外上述监测装置,造价较高,增加了电梯抱闸磨耗检测的成本,不利于广泛推广使用。The application number is 201510695385.2, and the name is a patent application for a method of monitoring elevator brake wear. It discloses a method for automatically monitoring elevator wear, mainly by connecting a display control box, a cable displacement sensor and The chip carrying the corresponding calculation program monitors wear and tear, which requires high sensitivity of components. Once the sensitivity is disturbed or weakened, the entire alarm and monitoring system will fail. In addition, the above-mentioned monitoring device is expensive, which increases the need for elevators. The cost of brake wear detection is not conducive to widespread promotion and use.
