The invention relates to the technical field of electromechanics, in particular to an elevator safety brake which comprises an elevator shaft, a lift car is slidably mounted in the elevator shaft, a traction machine is fixedly mounted at the top end of the elevator shaft, a steel wire rope matched with the lift car is arranged on the traction machine in a sleeving mode, and a plurality of sliding rods are arranged in the elevator shaft. A plurality of fixing plates matched with the sliding rods are evenly installed on the lift car, and speed reducing plates are fixedly installed in the fixing plates. The traction machine is provided with a speed measuring assembly used for detecting whether the traction machine breaks down or not. A speed reducing assembly used for reducing the falling speed of the lift car is arranged in the speed reducing plate. According to the elevator safety brake, the magnetic force of the first electromagnet is influenced by the rotating speed of a traction machine, so that connection of the first connector is controlled, after the first connector is connected, the third electromagnet is controlled to be powered on to generate magnetism, the clamping plate is driven to be clamped into the clamping groove, the falling speed of an elevator car is reduced, and the working stability of the elevator safety brake is improved.

    本发明涉及机电技术领域,具体为一种电梯安全制动器,包括:电梯井,所述电梯井内滑动安装有轿厢,所述电梯井的顶端固定安装有曳引机,所述曳引机上套设有与轿厢相互配合的钢丝绳,所述电梯井内设有多个滑杆,所述轿厢上均匀安装有多个与滑杆相互配合的固定板,所述固定板内固定安装有减速板;所述曳引机上设有用于检测曳引机是否产生故障的测速组件;所述减速板内设有用于降低轿厢坠落速度的减速组件。本发明通过设有第一电磁铁的磁力受曳引机转速的影响从而控制第一接头的接通,当第一接头接通后控制第三电磁铁通电产生磁性并驱动卡板卡入卡槽内,以此降低轿厢下坠速度,从而提高了电梯安全制动器工作的稳定性。
