The invention relates to a liftable trackless hoisting device, comprising: a hoisting frame comprising a frame body and a support rod in sliding connection with the frame body; the bearing mechanism comprises a hook for bearing a target object, and the hook is installed on the supporting rod; the driving mechanism is connected with the bearing mechanism and drives the bearing mechanism to move so as to drive the supporting rod to slide relative to the frame body; the energy storage mechanism is connected with the bearing mechanism; when the supporting rod slides down along the frame body under the action of the gravity of the supporting rod and/or the gravity of the target object, the energy storage mechanism rotates in the first direction to store the gravitational potential energy and rotates in the second direction to release the stored gravitational potential energy, so that the energy storage mechanism and the driving mechanism jointly drive the supporting rod and/or the target object to slide up along the frame body. By means of the mode, the target object cannot shake in the lifting process, the lifting safety is guaranteed, the lifting steps can be simplified, and energy is saved.
本发明涉及一种可升降式无轨起吊装置,包括:吊装架,包括架体及支撑杆,支撑杆与架体滑动连接;承载机构,包括承载目标物的挂钩,挂钩安装于支撑杆上;驱动机构,与承载机构连接,驱动承载机构运动以驱动支撑杆相对于架体滑动;蓄能机构与承载机构连接;支撑杆在自身重力和/或目标物的重力作用下沿架体下滑时,蓄能机构沿第一方向转动以将的重力势能贮存,并沿第二方向转动以将贮存的重力势能释放,使得蓄能机构与驱动机构共同驱动支撑杆和/或目标物沿架体上滑。通过上述方式,可使得起吊过程中目标物不会产生晃动,保证起吊的安全性,并且还能够简化起吊步骤及节能。
