The invention relates to the technical field of limiting mechanisms, in particular to a stroke limiting mechanism of a lifting device, and aims to solve the problems that a twisted rope is easy to block after being lifted to the topmost end and the twisted rope is easy to reverse after being used up. In order to solve the problem, the invention provides the stroke limiting mechanism of the lifting device, which comprises a lifting device body and a stroke limiting mechanism, the lifting device body comprises a roller for winding a twisted rope, and the roller is arranged outside the lifting device body; the stroke limiting mechanism comprises a spiral groove formed in one end of the roller, a limiting part connected with the lifting device body, and a sliding block and two limiting switches which are arranged in the limiting part; at least part of the sliding block enters the spiral groove; the spiral groove is used for guiding the sliding block to move between the two limiting switches in the limiting part; in the rotating process of the roller, the spiral groove drives the sliding block to move in the limiting part, and when the sliding block makes contact with the limiting switch, the roller stops rotating.
本发明涉及限位机构技术领域,具体而言,涉及一种提升装置的行程限位机构,本发明解决的问题:在绞绳升到最顶端容易卡死和避免绞绳用尽后容易反转的问题。为解决上述问题,本发明提供一种提升装置的行程限位机构,包括提升装置本体和行程限位机构;提升装置本体包括用于缠绕绞绳的滚筒,滚筒设于提升装置本体的外部;行程限位机构包括设于滚筒一端的螺旋槽、与提升装置本体连接的限位部、以及设于限位部内的滑块和两个限位开关;滑块的至少部分进入螺旋槽内;螺旋槽用于引导滑块在限位部内的两个限位开关间移动;其中,在滚筒转动过程中,螺旋槽带动滑块在限位部内移动,当滑块与限位开关接触时滚筒停止转动。
