The invention discloses a flat energy elevator safety brake device which is installed on the top or the bottom of a lift car, and a guide mechanism comprises a fixing block and a linear guide rail. The wedge-shaped block locking mechanism is arranged between the linear guide rail and one side surface of the elevator guide rail in a manner of sliding up and down along the linear guide rail; the adjusting mechanism is connected to the lower end of the wedge-shaped block locking mechanism and the bottom of the fixing block in a vertically telescopic manner; the electromagnet attraction mechanism is arranged in the adjusting mechanism; when an elevator runs normally, the electromagnet attraction mechanism is powered on and is in an attraction state, so that the adjusting mechanism is in a contraction state, and then the wedge-shaped block locking mechanism is separated from the surface of one side of the elevator guide rail; when the suspension part of the lift car is broken, the electromagnet attraction mechanism is powered off to trigger the adjusting mechanism to extend upwards, and then the wedge-shaped block locking mechanism is driven to move upwards along the linear guide rail till the wedge-shaped block locking mechanism is locked on the surface of one side of the lift guide rail. The anti-falling device is high in anti-falling safety.
本发明公开了一种平能电梯保险刹车装置,安装在轿厢的顶部或底部上,其中,导向机构包括固定块和直线导轨;楔形块锁紧机构沿直线导轨可上下滑动地设置在直线导轨和电梯导轨的一侧表面之间;调节机构可竖向伸缩地连接于楔形块锁紧机构的下端和固定块的底部上;电磁铁吸合机构设置在调节机构中;当电梯正常运行时,电磁铁吸合机构通电并处于吸合状态,使得调节机构处于收缩状态,进而使得楔形块锁紧机构与电梯导轨的一侧表面分离;当轿厢的悬挂件断裂时,电磁铁吸合机构断电而触发调节机构向上伸长,进而带动楔形块锁紧机构沿直线导轨向上运动,直到楔形块锁紧机构锁紧在电梯导轨的一侧表面上。本发明防坠安全性高。
