The invention discloses an elevator ascending overspeed protection device, and relates to the technical field of elevator overspeed protection, the elevator ascending overspeed protection device comprises two sliding rails, a car is arranged between the two sliding rails, the top end of the car is fixedly connected with two connecting blocks, and the top of one connecting block is provided with a mechanical braking device; the mechanical braking device comprises a sliding block, the top of one connecting block is fixedly connected with a supporting block, a sliding groove is formed in the top of the supporting block, a push rod and a trapezoidal block are slidably connected into the sliding groove, and the push rod is located on one side of the trapezoidal block. Through the arrangement of the mechanical braking assembly, normal work can still be achieved under the condition that an elevator is powered off, safe stopping of the elevator car is ensured, the surface of the sliding rail is clamped through the two braking wheels, enough friction force can be generated between the braking wheels and the sliding rail, and then the ascending speed of the elevator car is reduced; and the elevator car is stopped at a safe position.
本发明公开了一种电梯上行超速保护装置,涉及电梯超速保护技术领域,包括滑轨,所述滑轨的数量设置为两个,两个所述滑轨之间设有轿厢,所述轿厢的顶端固定连接有两个连接块,其中一个所述连接块的顶部设有机械刹停装置;机械刹停装置,包括滑块,其中一个所述连接块的顶部固定连接有支撑块,所述支撑块的顶部设有滑槽,所述滑槽内部滑动连接有推杆和梯形块,所述推杆位于梯形块的一侧。本发明通过机械刹停组件的设置,能够在电梯停电的情况下,仍可以正常工作,确保电梯轿厢的安全停止,通过两个制动轮夹住滑轨的表面,制动轮会与滑轨产生足够的摩擦力,进而来减速电梯轿厢的上行速度,将电梯轿厢停止在一个安全的位置。
