The invention discloses a rapid ejection lifting fire ladder, and relates to the technical field of fire fighting equipment. The rapid ejection lifting fire ladder comprises a main ladder body, a movable toothed plate and a [-shaped ejection ladder body, a frame groove is formed in the main ladder body, the two ends of the [-shaped ejection ladder body are inserted into an inner cavity of the frame groove, an inclined ring groove is formed in the rear face of the inner wall of the frame groove, a spring is movably connected to the inner wall of the inclined ring groove through a rotating shaft, one end of the spring extends into the frame groove and is fixedly connected with the movable toothed plate, and passive clamping teeth are welded to the face, opposite to the movable toothed plate, of the [-shaped ejection ladder body. According to the overall design of the rapid ejection lifting fire ladder, two supporting side rods of the [-shaped ejection ladder body are stuffed into the frame groove, use of the ladder is not affected when the ejection ladder is not ejected out, when the [-shaped ejection ladder body is not ejected out and used for being in lap joint with the wall face, a firefighter steps on pedal rods on the main ladder body to eject the [-shaped ejection ladder body out, and therefore, the fire ladder can be applied to fire scenes with changeable conditions.
本发明公开了一种快速弹射升降消防梯，涉及消防设备技术领域。该快速弹射升降消防梯，包括主梯、活动齿板和匚型弹射梯，所述主梯上开设有架槽、所述匚型弹射梯的两端插接于架槽的内腔中，所述架槽内壁的后面开设有斜环槽，所述斜环槽的内壁通过转轴活动连接有发条，所述发条的一端延伸至架槽中并与活动齿板固定连接，所述匚型弹射梯相对活动齿板的一面焊接有被动卡齿牙。该快速弹射升降消防梯，整体设计是将匚型弹射梯的两根支撑侧杆塞入架槽中，不影响在不弹射出来时梯子使用，在匚型弹射梯没弹射出来用于搭接在墙面上的同时，消防员踩踏着主梯上的踩踏杆将匚型弹射梯弹射出来，从而使消防梯能够应用与情况多变的火灾现场。
