The invention discloses a rolling type landing door heavy hammer assembly which comprises a guide pipe and a rolling type landing door heavy hammer, and the rolling type landing door heavy hammer is driven by a traction steel wire rope to move up and down in the guide pipe. The rolling type landing door heavy hammer comprises a heavy hammer body and at least one set of rolling wheel components arranged on the outer surface of the heavy hammer body, and rolling wheels in the rolling wheel components roll on the inner surface of the guide pipe. The invention relates to a heavy hammer running in a guide pipe in a rolling manner, which is used for solving the risk that people fall into a hoistway due to noise generated by overlarge gap between the guide pipe and the heavy hammer or overlarge gap caused by abrasion of a heavy hammer guide block or clamping stagnation caused by impurities and incapability of self-closing during running of a landing door heavy hammer.

    本发明公开的一种滚动式层门重锤组件,包括导管和滚动式层门重锤,所述滚动式层门重锤通过牵引钢丝绳带动在所述导管内上下运动,其特征在于,所述滚动式层门重锤包括重锤本体和设置在所述重锤本体的外表面上的至少一组滚轮部件,所述滚轮部件中的滚轮在所述导管的内表面上滚动。本发明是一种在导管中滚动运行的重锤,应用解决层门重锤在运行中因导管与重锤间隙过大,或因重锤导向块磨损导致的间隙过大而产生的噪音或因杂质引起的卡滞无法自闭带来人员跌落井道的风险。
