The invention discloses emergency early warning elevator equipment. The emergency early warning elevator equipment comprises an elevator shaft, wherein an elevator shaft cavity is formed in the elevator shaft, an elevator car capable of sliding up and down is arranged in the elevator shaft cavity, a lift car is arranged in the elevator car, a speed measuring mechanism is arranged on the lower sideof the lift car, the speed measuring mechanism comprises a centrifugal wheel cavity formed in the lower side of the lift car, the rear wall of the centrifugal wheel cavity is rotationally connected with a centrifugal wheel shaft, the outer circle surface of the centrifugal wheel shaft is fixedly connected with a centrifugal wheel, and four centrifugal block cavities with openings far away from one side of the centrifugal wheel are arranged on one side of the outer circle of the centrifugal wheel in an annular array mode. According to the emergency early warning elevator equipment, the runningspeed of an elevator can be automatically detected, and when the advancing speed of the elevator exceeds a threshold value, an emergency early warning system of the elevator is triggered, meanwhile,the device can automatically slow down the descending speed of the elevator and automatically inflate a cushion pad in the advancing process, and the cushion pad can reduce the damage to passengers inthe elevator caused by collision due to the fact that the speed is not reduced in time.
本发明公开的一种紧急预警电梯设备,包括电梯井,所述电梯井内设有电梯井腔,所述电梯井腔内设有能上下滑动的电梯轿,所述电梯轿内设有轿厢,所述轿厢下侧设有测速机构,所述测速机构包括设于所述轿厢下侧的离心轮腔,所述离心轮腔后壁转动连接有离心轮轴,所述离心轮轴外圆面固定连接有离心轮,所述离心轮外圆一侧环形阵列设有四个开口远离所述离心轮一侧的离心块腔,本发明能自动检测电梯的运行速度,当电梯的行进速度超过阈值时触发电梯的紧急预警系统,同时本装置可以自动减缓电梯的下行速度并且在行进的过程中自动给缓冲垫充气,缓冲垫可以降低减速不及时导致碰撞时对电梯内的乘坐人员产生的伤害。
