The invention relates to the technical field of wind power and buildings, and provides a manual descending device and a lifting system of lifting equipment. The manual descending device comprises a mounting base, a push rod, a swing rod and a pull rope, wherein a first through hole is longitudinally formed in the mounting base in a penetrating mode, and a guide rod which horizontally extends is arranged on the mounting base; a limiting block is formed at the top of the push rod, and the lower part of the push rod is slidably inserted into the first through hole; the side wall of the top of theswing rod is rotationally connected with one end of a connecting shaft, and the other end of the connecting shaft is used for being connected with a lock rod of a lifting mechanism of the lifting equipment; a strip-shaped hole which is used for allowing the guide rod to penetrate through is formed in the lower part of the swing rod, a spring sleeves the outer side of the guide rod, and the springis used for driving the bottom end of the swing rod to be separated from the limiting block of the push rod; one end of the pull rope is connected with the lower part of the swing rod, and the otherend of the pull rope is used for suspending a protective plate below a bottom plate of the lifting equipment through a pulley block; and the pull rope is used for driving the bottom end of the swing rod to abut against the limiting block of the push rod. According to the manual descending device and the lifting system of the lifting equipment, the lifting equipment can safely fall to the ground during power failure, and effective guarantee is provided for the safety of workers.

    本发明涉及风电、建筑技术领域,提供了一种升降设备的手动下降装置、升降系统。该手动下降装置包括:安装座,其纵向贯穿开设有第一通孔,安装座上设置有水平延伸的导杆;推杆,其顶部形成有限位块;推杆的下部可滑动的插设在第一通孔中;摆杆,其顶部的侧壁与连接轴的一端转动连接,连接轴的另一端用于与升降设备的提升机构的锁杆连接;摆杆的下部开设有穿设导杆的条形孔,导杆的外侧套设有弹簧,弹簧用于驱动摆杆的底端脱离推杆的限位块;拉绳,其一端与摆杆的下部连接,另一端通过滑轮组将防护板悬吊在升降设备的底板下方;拉绳用于驱动摆杆底端抵触在推杆的限位块上。本发明可实现断电时升降设备的安全落地,为工作人员的安全提供了有效保障。
