The invention discloses an elevator capable of preventing an elevator car from accidentally moving, and relates to the technical field of elevators. Comprising symmetrically-distributed T-shaped rails, the symmetrically-distributed T-shaped rails are jointly connected with a supporting frame in a sliding mode, the supporting frame is provided with a lift car, the supporting frame is connected with two sets of T-shaped cylinders which are distributed in a bilateral symmetry mode in a sliding mode, symmetrically-distributed speed reduction piston rods are connected into the T-shaped cylinders in a sealed and sliding mode, and wedge-shaped blocks are fixedly connected to the speed reduction piston rods. The supporting frame is in sliding connection with symmetrically-distributed sliding frames, the sliding frames are rotationally connected with retarding rings in a sealed mode, and the retarding rings are rotationally connected with monitoring rings in friction fit with the adjacent T-shaped rails in a sealed mode. The moving speed of the lift car is directly monitored through the monitoring ring, when the moving speed of the lift car exceeds a normal value, the hydraulic oil drives the wedge-shaped block to be attached to the T-shaped rail, the lift car is decelerated, and the problem that a brake cannot be triggered to brake the lift due to the fact that the service time of the lift is prolonged is solved.

    本发明公开了涉及电梯技术领域的一种防止轿厢意外移动的电梯。包括有对称分布的T形轨,对称分布的所述T形轨共同滑动连接有支撑框,所述支撑框安装有轿厢,所述支撑框滑动连接有左右对称分布的两组T形筒,所述T形筒内密封滑动连接有对称分布的减速活塞杆,所述减速活塞杆固接有楔形块,所述支撑框滑动连接有对称分布的滑动架,所述滑动架密封转动连接有缓速环,所述缓速环密封转动连接有与相邻所述T形轨摩擦配合的监测环。本发明通过监测环直接监测轿厢移动的速度,并在轿厢移速超过正常值时,通过液压油传动楔形块与T形轨贴合,对轿厢进行减速,防止由于电梯使用时长增加,而无法触发制动器对电梯进行制动的问题。
