The invention discloses a safety protection structure of an aviation rocket frame elevator landing door, a landing door is slidably connected in a landing door groove of a wall surface, a pre-tightening device is arranged between the landing door and the landing door groove, and the pre-tightening device comprises a multi-layer pre-tightening structure formed by a sliding rod, two side pull rods and a pre-tightening block; a multi-layer tightening structure is matched with a special belt connection mode and a pre-tightening block is added for balancing weight, so that an inward pre-tightening structure for the hoistway door is formed, the hoistway door is closed more tightly, and the situation that the hoistway door is driven to be opened and closed only through the connection relation with the door knife, and the hoistway door is slightly displaced when the hoistway door deforms and the car door knife is separated from the hoistway door is avoided; the landing door is not tightly closed, the lift car on the premise that the landing door is closed cannot run, locking and unlocking states are switched through a locking structure of the locating sleeve and the locating block on the landing door in cooperation with a power-on electromagnet, a power-off electromagnet and a magnet, and the situation that the landing door suddenly breaks down, and passengers inside and outside the landing door are injured is avoided.

    本发明公开了一种航空火箭架电梯厅门的安全保护结构,墙面的厅门槽内滑动连接有厅门,厅门和厅门槽之间设置预紧装置,预紧装置包括滑杆、两侧拉杆以及预紧块形成的多层预紧结构,通过多层收紧结构配合以特殊的皮带连接方式加以预紧块配重,形成向内对厅门的预紧结构,使得厅门闭合更加紧密,避免仅通过与门刀的连接关系带动厅门开合的方式,因厅门变形、轿门门刀脱离厅门时对厅门产生的细微位移,导致厅门闭合不紧密,进而使得以厅门关闭为运行前提的轿厢无法运行,通过定位套和定位块对厅门的锁止结构,配合以通、断电电磁铁和磁铁配合进行锁止、解锁状态切换,避免厅门突然故障,而对厅门内外乘客造成伤害。
