The invention relates to the technical field of cranes, in particular to a self-disassembly and assembly on-load displacement counterweight device and a crane. The self-disassembly and assembly on-load displacement counterweight device comprises a counterweight frame assembly arranged on a rotary table, the counterweight frame assembly comprises a counterweight seat, and a counterweight tray used for loading a counterweight block is movably hinged to the counterweight seat. A telescopic mechanism is movably connected between the counterweight seat and the counterweight tray, and the counterweight tray is driven to deflect in a reciprocating mode through telescopic movement of the telescopic mechanism so that counterweight displacement can be achieved. In addition, the counterweight frame assembly further comprises a counterweight hanging frame used for being upwards connected with a rotary table, and a lifting mechanism is movably connected between the counterweight hanging frame and the counterweight seat. According to the device, the function of carrying the counterweight on the rotary table for displacement can be more conveniently realized, the displacement operation of the counterweight is simpler, the problem of automatic disassembly and assembly of the crane counterweight is solved through the lifting mechanism, meanwhile, the functions of self disassembly and assembly of the crane counterweight and carrying of the counterweight for displacement are realized, the practicability is stronger, and the operation is simpler and more convenient.
本发明涉及起重机技术领域,尤其涉及一种自拆装带载变位的配重装置及起重机,包括用于设置在转台上的配重架总成,配重架总成包括配重座,配重座上活动铰接有用于装载配重块的配重托盘,配重座与配重托盘之间活动连接有伸缩机构,通过伸缩机构的伸缩活动带动配重托盘往复偏转以实现配重变位。另外,配重架总成还包括用于向上连接转台的配重挂架,配重挂架与配重座之间活动连接有升降机构。本发明能更为方便地实现在转台上携带配重进行变位的功能,让配重的变位操作更为简易,并且通过升降机构解决起重机配重的自动拆装问题,同时实现了起重机配重的自拆装和携带配重变位的功能,实用性更强,操作也更为简易方便。
