The invention provides a comb tooth safety protection device which is applied to automatic elevator equipment, and the automatic elevator equipment is an escalator or a moving sidewalk. The comb tooth safety protection device comprises an action connecting rod and an action rotating rod. The first tail end of the action connecting rod is connected to a comb plate of the automatic elevator equipment to form a first rotating pair. The first tail end of the action rotating shaft is connected with the second tail end of the action connecting rod to form a second rotating pair, a switch triggering mechanism is formed on the action rotating shaft, and the switch triggering mechanism is arranged near a safety switch of the automatic elevator equipment. When the comb plate moves abnormally, the action rotating shaft is driven to rotate through the first rotating pair and the second rotating pair, and the switch triggering mechanism makes contact with the safety switch so as to trigger the safety switch to act to stop running of the automatic elevator equipment. Detection of displacement of the comb plate in multiple directions can be achieved by only one safety switch, the device can be suitable for escalators of different specifications, such as escalators and moving sidewalks, even special-shaped escalators such as spiral escalators, and the product has the advantages of being low in cost, wide in applicability and convenient to maintain.
本发明提供一种梳齿安全保护装置,应用于自动电梯设备中,自动电梯设备自动电梯设备为自动扶梯或自动人行道;包括:动作连杆,动作连杆的第一末端连接在自动电梯设备自动电梯设备的梳齿板上以形成第一转动副;动作转轴,动作转轴的第一末端与动作连杆的第二末端相连以形成第二转动副,动作转轴上形成一开关触发机构,开关触发机构设置于自动电梯设备的安全开关的附近;于梳齿板发生异常位移时,通过第一转动副和第二转动副带动动作转轴转动,开关触发机构接触安全开关从而触发安全开关动作实现自动电梯设备停止运行。仅需一个安全开关就可以实现对梳齿板多个方向位移的检测,可以适用不同规格扶梯,如自动扶梯和自动人行道,甚至是螺旋扶梯等异形扶梯,使得产品具有成本低,适用性广,便于维护的优点。
