The invention discloses a hoisting mechanism capable of preventing a hoisting rope from being damaged by hoisting, and relates to the technical field of hoisting devices. The hoisting mechanism comprises crown blocks, an upper hanging frame and a lower hanging frame. A fixed pulley block is arranged in the upper hanger structure; a movable pulley block is arranged in the lower hanger structure; and the upper hanging frame is connected with the crown blocks, a hoisting rope is wound between the fixed pulley block of the upper hanging frame and the movable pulley block of the lower hanging frame in a penetrating manner, and the lower hanging frame is connected with a lifting appliance or a heavy object. According to the hoisting mechanism, compared with the characteristic that a certain distance must be kept between an upper hanging frame fixed pulley block and a lower hanging frame movable pulley block of a traditional hoisting mechanism, the upper hanging frame fixed pulley block and the lower hanging frame movable pulley block can be allowed to make contact with each other in the working process during hoisting, so that the phenomenon that because the upper hanging frame and the lower hanging frame of the traditional hoisting mechanism are close to each other and abrade the edge of a pulley, the hoisting rope is cut is avoided, and the hoisting rope is prevented from being damaged due to hoisting of the lower hanging frame; and meanwhile, the hoisting space occupied by the pulley blocks is reduced, the hoisting height is increased under the same condition, the hoisting capacity of equipment is improved, and economic benefits are improved.

    本发明公开了一种防冲顶损伤起重绳的起重机构,涉及起重装置技术领域,包括天车、上挂架及下挂架。上挂架结构内设有定滑车组;下挂架结构内设有动滑车组;上挂架与天车连接,上挂架的定滑车组和下挂架的动滑车组之间穿绕有起重绳,下挂架连接吊具或重物。本发明与传统起重机构的上挂架定滑车组与下挂架动滑车组之间必须保持一定距离的特点相比较,能够在吊装时,上挂架定滑车组与下挂架动滑车组在工作过程中允许相互接触,避免传统起重机构因上、下挂架靠近导致的磨绳和磨滑轮边缘而切割起重绳现象,防止因下挂架冲顶损伤起重绳;同时减小了滑车组占用的起吊空间,在同等条件下增加了起升高度,增加了设备的起吊能力,提高经济效益。
