Description

一种用于自动扶梯的钢塑组合式梯级 技术领域
本发明涉及一种电梯部件，具体是一种自动扶梯梯级，尤其涉及一种用于自动扶梯的钢塑组合式梯级。
背景技术
自动扶梯是一种以运输带方式运送行人的运输工具，一般是斜置。自动扶梯上设有供乘客站立的相互邻接的梯级，行人在扶梯的一端站上自动行走的梯级，便会被带到扶梯的另一端。梯级是特殊结构形式的四轮小车，各梯级的主轮轮轴与梯级链活套在一起，使得梯级在上分支保持水平，在下分支进行翻转。由于梯级数量众多，又是运动部件，因此自动扶梯性能和质量的好坏很大程度上取决于梯级的质量和性能。
梯级按结构可分为整体式和组装式两种，按材料可以分为铝合金、不锈钢以及铝合金与不锈钢组装式三种，其中：较常见的整体式梯级为铝合金整体压铸而成，其优势在于精度高、自重轻，其劣势在于梯级压铸成形难、废品率高；较常见的组装式梯级由踏板、踢板、框架等部分拼装组合而成，其优势在于强度高、应用范围广，其劣势在于，梯级整体重量偏高。
鉴于在自动扶梯额定功率固定的前提下，减轻梯级自重就意味着可以提高运载能力，因此有必要提供一种新的技术方案。
