The invention relates to the technical field of elevator use, and discloses a stall protection device for a vertical lifting elevator, which comprises a car body and two guide rail plates with a guiding function, and the guide rail plates are sleeved with speed reducing mechanisms; the speed reducing mechanism comprises connecting rods connected to the two sides of the guide rail plate in a sliding mode, and rotating wheels rotating on the side wall of the guide rail plate are arranged on the outer sides of the connecting rods. According to the protection device, when the compartment body stalls, the compartment body and the whole speed reducing mechanism can quickly move on the guide rail plate, the rotating wheels can rotate on the outer wall of the guide rail plate, the rotating speed can be increased, the stall sensing device works under the action of the rotating shaft when the speed reaches a set value, the telescopic rod is started to work, and the telescopic rod can be inserted into the limiting hole, so that the stall is prevented from being damaged. Therefore, the friction wheel stops rotating, the friction wheel and the wedge-shaped groove are in sliding connection instead of rotating connection, friction force is increased, the speed reduction effect can be achieved, and the safety problem caused by stall is effectively avoided.
本发明涉及电梯使用技术领域,且公开了一种用于垂直升降电梯的失速保护装置,包括厢体、以及具有导向功能的两个导轨板,所述导轨板上套接有减速机构;所述减速机构包括滑动连接在导轨板两侧的连接杆,所述连接杆的外侧设置有在导轨板侧壁上转动的转动轮。该保护装置,厢体在失速时,厢体和整个减速机构会在导轨板上快速运动,转动轮会在导轨板的外壁上转动,并且转动速度会变快,配合转动轴的作用,在速度达到设定值时,失速感应装置工作,通过启动伸缩杆工作,伸缩杆会插入到限位孔中,从而对限位轮进行限制,这样摩擦轮就会停止转动,会与楔形槽由转动连接变成滑动连接,摩擦力增加,从而可以实现减速的效果,有效的避免失速带来的安全问题。
