The invention discloses an elevator counterweight device which is provided with a counterweight frame, counterweight safety tongs, a counterweight wheel and a bearing jamming protection device. The bearing jamming protection device is provided with a wheel shaft baffle, a spring installation arm, a steel wire rope, a spring upper blocking piece, a speed limiter steel wire rope blocking piece, a spring and a spring lower blocking piece. The wheel shaft baffle plays a role in positioning the wheel shaft, and when the counterweight wheel rotates and the bearing is normal, the wheel shaft and the wheel shaft baffle do not rotate along with the counterweight wheel, and the bearing is blocked, the wheel shaft and the wheel shaft baffle can rotate along with the counterweight wheel; when the wheel shaft and the wheel shaft baffle rotate along with the counterweight wheel, the steel wire rope generates horizontal displacement along with the wheel shaft and the wheel shaft baffle, the spring upper baffle is pulled out of the spring installation arm, the spring acts upwards, and the counterweight safety tongs are lifted.

    本发明公开了一种电梯对重装置,具有对重框架、对重安全钳和对重轮,所述电梯对重装置还具有轴承卡阻保护装置;所述轴承卡阻保护装置具有轮轴挡板、弹簧安装臂、钢丝绳、弹簧上挡片、限速器钢丝绳挡片、弹簧和弹簧下挡片;所述轮轴挡板对轮轴起到定位作用,当对重轮转动,轴承正常时,轮轴和轮轴挡板不随对重轮转动,轴承卡阻时,轮轴、轮轴挡板会随对重轮转动;通过钢丝绳将轮轴与弹簧上挡片相连,当轮轴、轮轴挡板随对重轮转动,钢丝绳随之产生水平位移,将弹簧上挡片从弹簧安装臂中拉出,弹簧向上作用,提拉对重安全钳。
