According to the elevator protection device, an inclined first limiting sliding rail is arranged on a first supporting frame, a first elastic piece is arranged between a first brake block and the first supporting frame, and when an elevator car is abnormally weightless, the outer side of the first brake block gradually gets close to and makes contact with the inner wall of an elevator rail so as to brake the elevator car. When the lift car is overweight abnormally, the outer side of the second brake block gradually gets close to and makes contact with the inner wall of the lift rail so as to brake the lift car, and the lift is prevented from running upwards. According to the elevator car braking device, the first elastic piece is triggered to restore deformation through the abnormal weightlessness state of the first brake block when the elevator car falls, the first brake block slides along the first limiting sliding rail and makes contact with the side wall of the elevator track, and the elevator car is braked through friction force between the first brake block and the side wall of the elevator track; the life safety of elevator passengers is guaranteed to the maximum extent, the elevator is prevented from running upwards through the top rushing protection structure, and the function of protecting the safety of people and equipment is achieved.
本发明公开了一种电梯保护装置,第一支撑架上设有倾斜的第一限位滑轨,第一刹车块与第一支撑架之间设有第一弹性件,当轿厢异常失重时,第一刹车块的外侧逐渐靠近并接触电梯轨道内壁,以对轿厢进行制动。当轿厢异常超重时,第二刹车块的外侧逐渐靠近并接触电梯轨道内壁,以对轿厢进行制动,阻止电梯向上运行。本发明利用轿厢下坠时第一刹车块的异常失重状态触发第一弹性件恢复形变,使第一刹车块沿着第一限位滑轨滑动并与电梯轨道的侧壁接触,通过第一刹车块与电梯轨道侧壁的摩擦力来对轿厢进行制动,最大程度保证乘梯人员的生命安全,并通过冲顶保护结构阻止电梯向上运行,实现保护人身及设备的安全功能。
