The invention provides a construction elevator protective door and a linkage type frame erecting and door opening device, the protective door comprises a door frame and two door leaves, the door leaves are installed at the door frame through a locking structure, the locking structure comprises a supporting frame and a clamping and locking mechanism, and the clamping and locking mechanism forms clamping and locking on the closed door leaves; a magnet block is arranged on the clamping and locking mechanism, and the door opening state is maintained in a magnetic attraction mode; the bottom end of the supporting shaft is sleeved with a torsional spring, and elastic force is provided for door closing reset of the door leaf. The frame erecting and door opening device is installed on the elevator car, the pushing frame can stretch out and be correspondingly inserted into the locking structure, a frame erecting of the elevator car and the door frame is formed, the clamping and locking mechanism is unlocked, and the magnet block is made to move to the corresponding position where the door leaf is attracted through subsequent magnetic attraction. Automatic resetting and locking can be achieved, manual operation is reduced, and use is convenient. And the frame erecting and door opening device not only can realize the unlocking action of the protective door, but also can realize the connection between the elevator car and the protective door, so that the overall matching is enhanced, and the use safety is improved.

    本发明提供了一种施工电梯防护门及联动式的搭架开门装置,防护门包括门框及两块门扇,门扇通过锁紧结构安装在门框处,锁紧结构包括支撑框及卡锁机构,卡锁机构对闭合的门扇形成卡位锁定;卡锁机构上设有磁铁块,通过磁吸的方式维持开门状态;支撑轴的底端套设有扭簧,为门扇的关门复位提供弹力;搭架开门装置安装在电梯轿厢上,顶推架可伸出、对应插入锁紧结构内,形成电梯轿厢与门框的搭架,对卡锁机构进行解锁,并使磁铁块移动至后续磁吸吸附门扇的对应位置;其可实现自动的复位及上锁锁定,减少人为手动操作,便于使用;而搭架开门装置既可实现对防护门的解锁动作,也可实现电梯轿厢与防护门之间的连接,加强整体的配合,提高使用安全性。
