Description

一种家用电梯曳引驱动装置
技术领域
本实用新型涉及一种电梯组件， 尤其是一种家用电梯曳引驱动装置， 属于载人升降装置技术领域。 背景技术 曳引比为 2: 1的家用电梯驱动装置结构较为特殊， 既需要保证电梯运 行时的平稳、 安静， 又要尽量减小井道尺寸。 据申请人了解， 现有家用电梯的轿厢架普遍为一对立梁和固定在其下 端的下梁构成的 L形支架结构， 因此曳引驱动装置下的轿厢和对重都位于 顶部承载梁一侧。 结果受力的平衡性较差， 不利于保证电梯运行的平稳性。 实用新型内容 本实用新型的目的在于： 针对现有家用电梯 L形轿厢架结构存在的局 限性， 提供一种可以显著改善受力平衡性的家用电梯曳引驱动装置， 从而 有利于电梯的平稳运行。 为了达到上述目的， 本实用新型的家用电梯曳引驱动装置包括安置在 电梯井道顶部一侧的水平顶部承重梁， 所述顶部承重梁上安装具有曳引驱 动轮的曳引电机和对重绳头板固定座， 所述电梯井道远离顶部承重梁的侧 壁顶部固定轿厢绳头板固定座； 所述曳引驱动轮与电梯井道间距较小的一 侧悬垂的钢丝绳绕过对重绳轮后， 端头朝上延伸固定于对重绳头板固定座； 所述曳引驱动轮与电梯井道间距较大的一侧悬垂的钢丝绳绕过轿厢底部的 导向绳轮后， 端头朝上延伸固定于轿厢绳头板固定座。 这样， 对重与轿厢的绳轮分别在顶部承重梁两侧与曳引驱动轮构成了 曳引 比为 2: 1的动、 定滑轮组， 从而满足家用电梯的曳引动力设计要求， 同时， 重量匹配的对重与轿厢分别位于顶部承重梁的两侧， 使整个驱动装 置的受力平衡， 保证了家用电梯的平稳运行。 此外， 对重紧邻井道侧壁使 得轿厢可以充分利用井道空间， 因此提高了电梯井道的利用率。
本实用新型进一步的完善是， 所述曳引驱动轮与电梯井道间距较大的 一侧悬垂的钢丝绳绕过轿厢底部两侧的一对轴线与曳引驱动轮轴向平行的 导向绳轮后， 端头朝上延伸固定于轿厢绳头板固定座。
本实用新型更进一步的完善是， 所述对重绳轮的轴线与曳引驱动轮的 轴向垂直。
本实用新型再进一步的完善是， 所述顶部承重梁由一对开口朝外的槽 钢制成。
