The invention relates to an emergency braking anti-falling device for an elevator. The elevator clamp comprises a clamp seat body in floating connection with a lift car through a positioning spring, a guide rail passes through the clamp seat body, when an elevator is braked emergently, the clamp seat body bears the gravity from the lift car, and the gravity action lines of the lift car to the clamp seat body are located on the two sides of the center line of the guide rail; the bearing device is arranged between the upper end of the clamp seat body and the lift car and is positioned beside the center line of the guide rail; and the at least two clamping pieces are arranged in the clamp seat body, are positioned on the side of the guide rail and can move relative to the guide rail. According to the invention, the clamping force can be instantly changed along with the change of the load in the actual operation condition of the elevator, so that the emergency braking deceleration of the lift car can become a constant value and is not in a change range any more, and the device is suitable for elevators with various loads.
本发明涉及一种电梯紧急制动防坠落装置。本发明包括与轿厢通过定位弹簧浮动相连的钳座体,导轨经过所述钳座体,当电梯紧急制动时,所述钳座体承受来自轿厢的重力,所述轿厢对所述钳座体的重力作用线位于所述导轨中心线的两侧;承重装置,设于所述钳座体上端与所述轿厢之间在位于所述导轨中心线的旁侧;安装于所述钳座体内的至少两个夹持件,所述至少两个夹持件位于所述导轨旁侧且能够相对所述导轨活动。本发明中,夹持力能随电梯实际运行工况中载荷的变化而即时改变,从而能够使轿厢的紧急制动减速度成为恒定值,从而不再处于变化范围之中,适用于各种载荷电梯。
