Rope ladder head
The invention provides a rope ladder head. The rope ladder head comprises a ladder head main body; the ladder head main body comprises a main frame, a pulley frame, a pulley, a connecting rod mechanism and a self-locking plate; the pulley frame is telescopically installed at the top end of the main frame, the two ends of the pulley are rotatably installed in the pulley frame correspondingly, and the bottom end of the pulley frame is open; the self-locking plate is hinged to the pulley frame and located below the pulley; one end of the connecting rod mechanism is hinged with the main frame, andthe other end of the connecting rod mechanism is hinged with the end, away from the pulley frame, of the self-locking plate; when the pulley frame is in a shrink state, the connecting rod mechanism drives the self-locking plate to overturn to open an opening in the bottom end of the pulley frame; when the pulley frame is in an extending state, the connecting rod mechanism drives the self-lockingplate to overturn to lock the opening in the bottom end of the pulley frame; and a containing area for preventing a ground wire from being disengaged is formed between the pulley and the self-lockingplate, so that the rope ladder head is prevented from being disengaged from the ground wire.
本发明提供了一种软梯头，包括梯头主体；梯头主体包括主框架、滑轮框架、滑轮、连杆机构及自锁板；滑轮框架可伸缩安装在主框架的顶端，滑轮的两端分别可转动安装在滑轮框架内，且滑轮框架的底端开口；自锁板与滑轮框架铰接，且位于滑轮的下方；连杆机构的一端与主框架铰接，连杆机构的另一端与自锁板远离滑轮框架的那端铰接；当滑轮框架处于收缩状态时，连杆机构带动自锁板翻转打开滑轮框架底端的开口；当滑轮框架处于伸出状态时，连杆机构带动自锁板翻转封锁滑轮框架底端的开口，滑轮与自锁板间形成防止导地线脱离的放置区，避免软梯头从导地线上脱出。
