The invention relates to the field of elevator braking, in particular to an elevator braking protection system. The elevator braking protection system comprises an elevator braking disc, a braking rod, a fixing seat and a driving device used for driving the braking rod, wherein the braking rod penetrates through the fixing seat, the elevator braking disc is provided with at least one hole groove matched with the braking rod, the driving device is an electromagnet, the braking rod is provided with a metal plate attracted by the electromagnet, the braking rod penetrates through the electromagnet, the braking rod is sleeved with a spring, and the spring is located between the electromagnet and the metal plate. When an elevator stops normally, the electromagnet is powered off, the metal plate drives the braking rod to pop out and abut against the elevator braking disc under the action of elastic force of the spring, at the moment, if an elevator contracting brake fails and sliding occurs, the elevator braking disc starts to rotate in a sliding manner, the braking rod can be embedded into the hole groove in the elevator braking disc due to rotation of the elevator braking disc, and bolt type mechanical braking is achieved. Therefore, the life safety of elevator passengers can be effectively protected, the loss caused by top rushing damage of equipment is avoided, and the elevator braking protection system is suitable for wide popularization.
本发明涉及电梯制动领域,尤其涉及一种电梯制动保护系统,包括电梯制动盘、括制动杆、固定座和用于驱动所述制动杆的驱动装置,制动杆贯穿固定座,电梯制动盘上至少设置有一个与制动杆相配合的孔槽,驱动装置为电磁铁,制动杆上设置有与电磁铁相吸合的金属板,制动杆贯穿电磁铁,制动杆上套有弹簧,弹簧位于电磁铁和金属板之间。电梯正常停梯时,电磁铁断电,金属板在弹簧弹力作用下带动制动杆向外弹出并顶在电梯制动盘上,此时如果电梯抱闸失效溜车,电梯制动盘开始溜车旋转,制动杆会因电梯制动盘旋转嵌入电梯制动盘上的孔槽内,实现门栓式的机械制动,进而可以有效保护乘梯人员的生命安生,避免设备因冲顶损坏造成损失,适合广泛推广。
