The invention discloses a car locking device which comprises an elevator shaft and a car arranged in the elevator shaft in a liftable mode. The at least two movable limiting mechanisms are fixedly connected to the bottom end of the lift car; the driving mechanism is used for controlling the multiple movable limiting mechanisms to stretch out and draw back synchronously and is in transmission connection with the movable limiting mechanisms; the limiting mechanism is used for being fixed in the elevator shaft and located below a landing door sill, the limiting mechanism is connected with all the movable limiting mechanisms in a matched mode, and all the movable limiting mechanisms are limited in the limiting mechanism after extending out. A stable supporting connection relation is established between the bottom end of the lift car and the elevator shaft, the situation that an elevator is damaged due to unbalance loading when heavy goods are conveyed into and out of the lift car is effectively prevented, and the beneficial effects that the structure is simple, cost is saved, and safety is improved are achieved.
本发明公开了一种轿厢锁紧装置,包括电梯井,以及可升降设置在所述电梯井内的轿厢;至少两个活动限定机构,其固定连接在所述轿厢的底端;用于控制多个所述活动限定机构同步伸缩的驱动机构,其与各所述活动限定机构传动连接;用于固定在所述电梯井内且位于厅门地坎下方的限位机构,其与各所述活动限定机构相配合连接,并使各所述活动限定机构伸出后限定在所述限位机构内。本发明,将轿厢底端与电梯井之间建立稳定的支撑连接关系,有效防止重货物运送进出轿厢时造成偏载对电梯造成破坏,具有结构简单、节省成本、提升安全性的有益效果。
