The invention discloses a variable counterweight device, a displacement method thereof and a crane, the variable counterweight device comprises a counterweight arranged below a winch box, the rear ends of the left side and the right side of the winch box are respectively hinged with a support swing arm, and the other end of each support swing arm is provided with a counterweight hooking rod used for hooking the counterweight; a first limiting groove is formed in the top face of the balance weight and used for being matched with a limiting strip at the bottom of the winch box so as to limit the balance weight to linearly move front and back and achieve left-right limiting of the balance weight. Driving cylinders are arranged at the front ends of the left side and the right side of the winch box respectively and used for driving the supporting swing arms on the corresponding sides to rotate, so that the counter weight linearly moves front and back, and displacement is achieved; and the counterweight is provided with an oblong hole for the counterweight hanging rod to slide when the counterweight linearly moves back and forth. The device has the advantages of being simple in hydraulic system, low in control difficulty and low in cost, and meanwhile the requirement of counterweight linear displacement for the lower space is low.

    本发明公开了一种可变位配重装置、其变位方法及起重机,所述可变位配重装置包括设置在卷扬箱下方的配重,卷扬箱左右侧后端分别铰接一支撑摆臂,支撑摆臂另一端具有配重挂接杆,用于挂接配重;配重顶面设置第一限位槽,用于配合卷扬箱底部的限位条,以限制配重做前后直线移动并实现配重左右限位;卷扬箱左右侧前端分别设置一驱动缸,用于驱动对应侧支撑摆臂旋转,使得配重前后直线移动,实现变位;配重上开设有当其前后直线移动时,供配重挂接杆滑动的长圆孔。本发明具有液压系统简单、控制难度低、成本低的优点,同时配重直线变位对下部空间要求低。
