The invention relates to the field of hoisting devices, and provides a hoisting clamp, a hoisting machine and a guide wheel assembly used for hoisting an operation machine. In the hoisting process, the bearing frame is firstly placed on the peripheral face of the guide wheel and then slides to the position between the guide wheel and the tensioning device along the peripheral face. Then the sliding clamping piece slides to the position between the guide wheel and the tensioning device relative to the bearing frame, then the top of the sliding clamping piece is pulled in the direction close to the guide wheel, and the bottom of the sliding clamping piece is made to move in the direction of the tensioning device till the limiting piece enters the tensioning device. And finally, the supporting frame is lifted upwards through the lifting rope, at the moment, the supporting piece abuts against the position between the bottom of the sliding clamping piece and the guide wheel, the supporting piece can provide upward lifting force for the sliding clamping piece and can limit the bottom of the sliding clamping piece to rotate in the direction away from the tensioning device, and a limiting piece on the sliding clamping piece abuts against the top of the inner side of the tensioning device. And the tension of the lifting rope is transmitted to the tensioning device, so that the lifting of the guide wheel assembly is realized.
本发明涉及起吊装置领域,提供一种吊装夹具和起吊机械,用于起吊作业机械的导向轮组件。在起吊时,首先使支承架放置到导向轮的外周面上,然后沿外周面滑动至导向轮与张紧装置之间。随后使滑动卡件相对支承架滑动至导向轮与张紧装置之间,然后向靠近导向轮的方向拉动滑动卡件的顶部,使滑动卡件的底部向张紧装置的方向运动,直至限位件进入张紧装置内。最后通过吊绳向上提拉支承架,此时支撑件抵紧在滑动卡件的底部与导向轮之间,支撑件可为滑动卡件提供向上的提升力,且可限制滑动卡件的底部向远离张紧装置的方向转动,滑动卡件上的限位件抵紧在张紧装置的内侧顶部,将吊绳的拉力传导到张紧装置上,以实现导向轮组件的提升。
