The invention discloses an elevator safety device. When braking force is increased due to speed droop and the like and exceeds a set value, a first elastomer can move backwards by virtue of a feedbackdevice, so that the pressure of a braking body on a guide rail is reduced, the magnitude of the braking force is automatically controlled, proper braking force is generated, the braking force can becontinuously adjusted within a large range, the braking force can be automatically kept at the set value even if the friction factor is increased due to speed droop in a braking process, so that the braking deceleration is generally kept constant, the impact on passengers is reduced, the risk of accidental injury to the passengers is reduced, the maximum stress value of elevator car parts is greatly reduced, and an elevator car and counterweights are prevented from being damaged. The elevator safety device has the advantage of the compact and simple structure, the braking force can be continuously adjusted within the large range, and the braking force is automatically kept at the set value, so that the braking deceleration is generally kept constant. The invention further discloses an elevator. The elevator comprises the elevator safety device.

    本发明公开了一种电梯安全装置,当制动力由于速度的降低等原因增加时,制动力超过设定值时,能够通过反馈装置使第一弹性体向后移动,从而减小制动体对导轨的压力,自动控制制动力大小,产生合适的制动力,可以在较大的范围内连续调整制动力,在制动过程中即使摩擦系数由于速度的减小而增加时仍然能够自动将制动力保持在规定值,使制动减速度大体保持恒定,减小对乘客的冲击,降低乘客受到意外伤害的风险,大大降低电梯轿厢部件受力的最大值,避免损坏轿厢和对重部件。该电梯安全装置,结构紧凑简单,可在较大的范围内连续调整制动力,自动将制动力保持在规定值,使制动减速度大体保持恒定。本发明还公开了一种包括所述电梯安全装置的电梯。
