An automatic unhooking device for steel structure hoisting comprises an inverted-U-shaped ring, an outer pipe, an inner rod and a spring and is characterized in that a sling is arranged at the top end of the inverted-U-shaped ring, the outer pipe is a steel pipe with a certain length, one end of the outer pipe is fixedly arranged on the outer edge of a hole, the spring is arranged between the inner rod and the outer pipe, one end of the spring is welded to the outer side of the inverted-U-shaped ring, and the other end of the spring is welded to the outer side of the inverted-U-shaped ring. When the inner rod is used for hoisting operation, the limiting rod is fixed in the limiting groove along the outer pipe sliding way, a hoisted object and the inverted-U-shaped ring are connected and fixed, the hoisted object is hoisted to a to-be-installed position through a steel wire rope on the upper portion of the inverted-U-shaped ring to be installed, and after installation is completed, the limiting rod is shifted through a thin rope connected with the limiting rod, and then the hoisted object is lifted to the to-be-installed position. The inner rod limiting rod rebounds into the outer pipe along the sliding way through the elastic force of the spring to achieve automatic unhooking. The automatic unhooking device for steel structure hoisting has the advantages that the automatic unhooking device is simple in structure and convenient to manufacture, the construction speed is increased, the construction safety is guaranteed, and the engineering cost is reduced.

    一种用于钢结构吊装的自动脱钩装置,包括倒U型环、外管、內杆、弹簧,其特征在于:所述倒U型环的顶端设有吊索,所述外管为具有一定长度的钢管,外管的一端固设在一个孔洞的外沿,所述弹簧设置在內杆与外管之间,弹簧一端焊接在倒U型环外侧,弹簧另一端与內杆限位杆固定,其中:內杆在吊装作业时,限位杆沿外管滑道固定在限位槽内,将被吊物与倒U型环连接固定,通过倒U型环上部钢丝绳吊至待安装位进行安装,安装完毕后通过与限位杆连接细绳拨动,利用弹簧弹力将內杆限位杆沿着滑道回弹至外管内实现自动脱钩。本发明的用于钢结构吊装的自动脱钩装置具有自动脱钩装置结构简单、制作方便,提高施工速度,保证施工安全和降低工程成本的优点。
