The invention relates to the technical field of elevator equipment, and discloses a gear and rack elevator frame assembly. A self-locking assembly comprises a transmission shaft fixedly connected with an output shaft of a speed reducer, and the left side of the outer surface of the transmission shaft is movably sleeved with a first support; a first pawl matched with a first ratchet wheel fixedly installed on the left side of the inner cavity of the gear is in pin joint with the interior of the first support, a second support movably sleeves the right side of the outer surface of the transmission shaft, and a second ratchet wheel matched with a second pawl fixedly installed on the right side of the inner cavity of the gear is in pin joint with the interior of the second support. According to the gear and rack elevator frame assembly, the self-locking assembly and a structure on the self-locking assembly are arranged, and in the process that the speed reducer rotates forwards and backwards and drives the lift car assembly and goods on the lift car assembly to move up and down, the self-locking action can be formed on the lift car assembly at any time period; and the problem of falling accidents of the lift car assembly and goods on the lift car assembly caused by accidental power failure is effectively avoided.

    本申请涉及提升机设备技术领域,且公开了一种齿轮齿条提升机框架组件,自锁组件包括与减速机的输出轴固定连接的传动轴,传动轴外表面的左侧活动套接有第一支架,且在第一支架的内部销接有与固定安装在齿轮内腔左侧的第一棘轮相互配合的第一棘爪,传动轴外表面的右侧活动套接有第二支架,且在第二支架的内部销接有与固定安装在齿轮内腔右侧的第二棘爪相互配合的第二棘轮。本申请提供的一种齿轮齿条提升机框架组件,对于自锁组件及其上结构的设置,在减速机正反转并带动轿厢组件及其上的货物上下移动的过程中,在任意时间段都可对轿厢组件形成自锁动作,有效避免了因意外断电而造成轿厢组件及其上的货物发生下坠事故的问题。
