The invention relates to a puller for quickly disassembling brake drums. The puller comprises a lead screw, a brake drum supporting rod connected to the lead screw in a lifting mode through screw-thread fit and a top plate connected to one end of the lead screw, the brake drum supporting rod is perpendicular to the lead screw, the lead screw is rotationally arranged on the top plate, and the brakedrum supporting rod is of a telescopic structure; and at least one end of the brake drum supporting rod is of a lead screw jack structure. Through cooperation of the brake drum supporting rod, the top plate and the lead screw, when a vehicle is maintained or repaired, wheels and tires do not need to be disassembled, the brake drum can be rapidly and effectively disassembled, operation is easy andconvenient, time and labor are saved, and the operation efficiency can be greatly improved; the puller is suitable for quickly dismounting brake drum of rear wheels of vehicles, such as trucks, largebuses and semitrailers with larger load capacity and other wheels with the brake drums of the concave structures.

    本发明涉及用于快速拆卸刹车鼓的拉码,包括有丝杆、通过螺纹配合可升降连接于丝杆上的刹车鼓支撑杆及连接于丝杆一端的顶板,刹车鼓支撑杆垂直于丝杆设置,丝杆可转动设置于顶板上,刹车鼓支撑杆为可伸缩结构,且刹车鼓支撑杆至少一端为丝杆千斤顶结构。本发明通过刹车鼓支撑杆、顶板与丝杆配合,在车辆保养或维修时,无需拆下车轮及轮胎,可快速有效的拆卸刹车鼓,操作简单方便,省时省力,可大大提高作业效率,适用于货车、大型客车、半挂车等载重量较大车辆的后轮以及其它刹车鼓为内凹结构的车轮的刹车鼓快速拆卸。
