The invention discloses a hoisting device and method for replacing a winding drum of a hot rolling coiler, the hoisting device comprises an upper body and a lower body which are connected with each other, a hoisting ring is fixedly arranged above the upper body, a balancing weight slideway is arranged below the upper body, and a balancing weight capable of reciprocating along the slideway is arranged in the slideway; an oil cylinder is fixedly arranged on the outer side below the lower body, a winding drum contact device is arranged at the lower end, lifting hooks are arranged on the two sides of the winding drum contact device, and a winding drum is lifted through the lifting hooks. The hoisting device is hoisted by a crown block and moved into a dismounting position, a hoisting belt at the hoisting position surrounds the winding drum, the hoisting belt is tensioned by a hook, a balancing weight is adjusted to enable a hoisted object to reach a horizontal state, the winding drum is horizontally hoisted, a hydraulic oil cylinder is adjusted, the winding drum is inclined by a certain angle, and the winding drum is moved out by the crown block; according to the method, the efficiency of replacing the winding drum can be efficiently improved, the manpower investment can be reduced, meanwhile, the construction time is greatly shortened, large-tonnage and steel wire rope carrying and erecting work is avoided, and the safety danger coefficient of construction is reduced.
本发明公开了一种更换热轧卷取机卷筒吊运装置及方法,吊运装置包括相互连接的上、下两部分本体,上本体的上方固定设置吊环,下方设置配重块滑道,滑道内设置能够沿滑道往复运动的配重块;下本体的下方外侧固定设置油缸,下方端部设置卷筒接触装置,卷筒接触装置的两侧设置吊钩,通过吊钩将卷筒吊起。天车吊起吊运装置,移进拆卸位置,将吊运位置吊带环绕卷筒,用钩子拉紧,调整配重块使其吊物达到水平状态,将卷筒水平吊起,并调整液压油缸,将卷筒倾斜一定角度,用天车将卷筒移出,卷筒的安装顺序与拆卸相反执行,该方法能够高效的提高更换卷筒的效率,可以减少人力的投入,同时极大的缩短施工时间,避免了大吨位及钢丝绳的搬运架设工作,降低了施工的安全危险系数。
