The invention discloses a method for dismantling a temporary supporting hanging beam tool of a crane. The method comprises the following steps of a, hanging a hanging bar by using a main hook of a gate seat crane, and dismantling a connecting pin shaft between a supporting hanging beam and a top area of a tower body of a knuckle crane; B, adjusting the angles of a main arm rod and an auxiliary arm rod of the knuckle crane, placing the main arm rod and the auxiliary arm rod on a rest seat, and driving the supporting hanging beam to move along with the main arm rod and the auxiliary arm rod by the main hook of the gate seat crane; c, placing a temporary storage support on the arm rods of the knuckle crane through a sea crane to be fixed; d, after a single hook of the sea crane is used for hanging the hanging bar, dismounting a connecting pin shaft of the supporting hanging beam and a main arm rod area; e, after the gate seat crane and the sea crane are matched to hoist one side of the supporting hanging beam to the temporary storage support on the arm rods to be fixed, removing a single-hook hoisting point of the sea crane; f, hanging the hanging bar through double hooks of the sea crane, hanging a balancing weight below a hanging point at one side of the hanging bar, and connecting a hanging point at the other side of the hanging bar with the temporary supporting hanging beam; and g, lifting the double hooks of the sea crane, and moving out the supporting hanging beam from the side surface of the crane to finish the dismantling operation. The problem of dismantling the supporting hanging beam is solved through the method.

    本发明公开吊车临时支撑吊梁工装拆除方法,包括以下步骤:a、使用门座吊主钩挂设吊杠,拆开支撑吊梁与折臂吊塔身顶部区域的连接销轴;b、调整折臂吊主副臂杆的角度,将主副臂杆放置在休息座上,门座吊主钩带着支撑吊梁跟随主副臂杆移动;c、使用海吊将临时存放支架放置在折臂吊臂杆上固定;d、使用海吊单钩挂设吊杠后,拆开支撑吊梁与主臂杆区域的连接销轴;e、门座吊和海吊配合将支撑吊梁一侧吊运至臂杆上的临时存放支架上固定后,撤掉海吊单钩吊点;f、海吊双钩挂设吊杠,在吊杠一侧吊点下方挂设配重块,另一侧吊点连接临时支撑吊梁;g、提升海吊双钩,将支撑吊梁从吊车侧面移出,完成拆除作业。本发明解决了拆除支撑吊梁的难题。
