The invention discloses an escalator step chain breakage distributed braking device which comprises circulating step chains arranged on the two sides of an escalator or a moving sidewalk, and is characterized by further comprising a distributed braking device body which is provided with a plurality of braking units distributed in different working sections of the step chains. When the escalator control system detects the step chain breakage situation and outputs an execution signal to the distributed braking device, all braking units of the distributed braking device clamp and press chain plates on the two sides of the step chain at the same time and safely stop the broken step chain within the required deceleration range. According to the step chain braking device, reliable braking can be achieved when the step chain is broken at any position, stable braking force is provided through the distributed braking units, and in the braking process, the safety of passengers is protected, and parts are prevented from being damaged.
本发明公开的一种自动扶梯梯级链断裂分布式制动装置,包括:设置在自动扶梯或自动人行道梯路两侧的循环梯级链条,其特征在于:还包括一种分布式制动装置,所述分布式制动装置具有分布在梯级链的不同工作区段的多个制动单元,当自动扶梯控制系统检测到梯级链断裂情形并输出执行信号给分布式制动装置时,分布式制动装置的各制动单元同时夹压梯级链条两侧的链板并在要求的减速度范围内安全制停断裂的梯级链。本发明在梯级链于任何位置断裂时均能可靠制停,分布的制动单元提供了平稳的制动力,制动过程即保护了乘客安全又保持了部件不受损伤。
