The invention provides a rope changing device, a rope changing method and engineering machinery. The rope changing device comprises a winding drum clamping mechanism, a driving mechanism and a pre-tightening mechanism. The winding drum clamping mechanism comprises a first clamping piece and a second clamping piece which are oppositely arranged, wherein the opposite sides of the first clamping piece and the second clamping piece are used for detachably clamping a winding drum. The side, deviating from the second clamping piece, of the first clamping piece is connected to the driving mechanism, and the side, deviating from the first clamping piece, of the second clamping piece is connected to the pre-tightening mechanism. According to the rope changing device, an old rope can be recycled, a new rope can be installed, mechanical operation is achieved, the labor intensity is greatly reduced, pre-tightening force can be provided while the new rope is installed, a lifting hook and a load do not need to be used for extra pre-tightening, the rope changing process is simplified, and time and labor are saved.

    本发明提供一种换绳装置、换绳方法及工程机械,其中换绳装置包括卷筒夹持机构、驱动机构以及预紧机构,卷筒夹持机构包括相对设置的第一夹持件和第二夹持件,第一夹持件和第二夹持件相对的一侧用于可拆卸地夹持卷筒;第一夹持件背离第二夹持件的一侧连接于驱动机构,第二夹持件背离第一夹持件的一侧连接于预紧机构。该换绳装置既可以回收旧绳,又能够安装新绳,实现了机械化操作,大幅降低劳动强度,且在安装新绳的同时即可提供预紧力,无需再利用吊钩和载荷进行额外的预紧,简化了换绳流程,省时省力。
