The invention discloses a landing door safety protection device. A first hand clamping prevention device or a second hand clamping prevention device is mounted in a gap between a landing door and a door pocket stand column, the first hand clamping prevention device and the door pocket stand column form a connecting rod mechanism, when foreign matter enters a clamped area and the landing door is pushed in, a first movable vertical plate is touched, a rotating assembly is driven, the rotating assembly rotates to impact a first dual-frequency contactor, the first dual-frequency contactor is converted into the normal-open state from the normal-close state, a landing door system loop is broken, and the landing door stops the opening action. The second hand clamping prevention device and the door pocket stand column form an elastic reset mechanism, when the foreign matter enters the clamped area and the landing door is pushed in, a second movable vertical plate is pushed, a trigger of a second dual-frequency contactor connected to the second movable vertical plate transversely moves to leave a main body, and is converted into the normal-open state from the normal-close state, the landingdoor system loop is broken, and the landing door stops the opening action. The device has the advantages that hands can be effectively prevented from being clamped at any position, and meanwhile, automatic resetting is achieved.
本发明公开一种厅门安全保护装置,厅门与门套立柱间隙中安装第一防夹手装置或第二防夹手装置,第一防夹手装置与门套立柱形成连杆机构,异物进入被夹区域,厅门推入时触碰第一活动立板,带动转动组件,转动组件转动撞击第一双频接触器,第一双频接触器由常闭状态转换为常开状态,断开层门系统回路,厅门停止开门运动;第二防夹手装置与门套立柱形成弹性复位机构,异物进入被夹区域,厅门推入时推动第二活动立板,连接于第二活动立板的第二双频接触器的触发器平移离开主体,由常闭状态切换为常开状态,断开层门系统回路,厅门停止开门运动。本发明的优点是能在任何位置有效防止手被夹,同时能自动复位。
