The invention relates to the technical field of lifting appliance devices, and discloses an automatic unhooking lifting appliance. The automatic unhooking lifting appliance comprises a fixing frame, a lifting hook, an unhooking assembly and a first driving piece; the lifting hook comprises a lifting hook body and a locking part, one end of the lifting hook body is rotationally arranged on the fixing frame, a bent hook is arranged at the other end of the lifting hook body, and the locking part is arranged on the lifting hook body; the unhooking assembly comprises an elastic piece and a locking ring, the two ends of the elastic piece are connected with the bent hook and the locking ring respectively, the locking ring is slidably connected to the bent hook through the elastic piece, and the locking ring can be matched with the locking part in a clamped mode so as to block an opening of the bent hook; or, the locking ring is separated from the locking part and slides under the driving of the elastic piece so as to expose the opening of the bent hook; the output end of the first driving piece is hinged to the lifting hook body; and when the locking ring exposes the opening of the bent hook, the first driving piece drives the lifting hook body to rotate relative to the fixing frame, so that the opening of the bent hook faces downwards. The bent hook can be opened by the locking ring through the elastic piece, the structure is simplified, and the automatic unhooking efficiency is improved.

    本发明涉及吊具装置技术领域,公开了一种自动脱钩吊具。自动脱钩吊具包括固定架、吊钩、脱钩组件和第一驱动件。吊钩包括吊钩主体和锁止部,吊钩主体的一端转动设置于固定架上,吊钩主体的另一端具有弯钩,锁止部设置于吊钩主体上。脱钩组件包括弹性件和锁环,弹性件的两端分别与弯钩和锁环相连,锁环通过弹性件滑动连接于弯钩上,锁环能够与锁止部卡接配合,以封堵弯钩的开口。或者,锁环与锁止部脱离卡接并在弹性件的驱动下滑动,以打开弯钩的开口。第一驱动件的输出端与吊钩主体铰接相连。锁环打开弯钩的开口时,第一驱动件驱动吊钩主体相对于固定架转动,以使弯钩的开口朝下。通过弹性件实现锁环打开弯钩,简化了结构,提高了自动脱钩效率。
