The invention discloses a joint-adding heightening device, a joint-adding heightening method and a crane. The joint-adding heightening device comprises a truss telescopic arm; the truss telescopic arm comprises a first telescopic joint and a second telescopic joint; the first telescopic joint is connected with a vehicle body to serve as a jacking sleeve frame of the crane; the second telescopic joint is inserted into the first telescopic joint and is matched with the first telescopic joint in a telescopic mode; a lifting frame is arranged below the second telescopic joint and is connected with the first telescopic joint through a steel wire rope pulley block; and a standard joint guide door is arranged at the bottom of the first telescopic joint, and a standard joint used for joint adding enters the first telescopic joint from the standard joint guide door and then is connected with the second telescopic joint, so that the adding of the standard joint is completed. The joint-adding heightening device is convenient and efficient; the defects of application of a telescopic truss structure are overcome; the market applicability is improved; the requirements of general market hoisting weight and height are met; and when the requirement of a higher hoisted object is met, height increasing is achieved by adding joints.

    本发明公开了一种加节增高装置和加节增高方法及起重机,其中加节增高装置包括桁架伸缩臂,桁架伸缩臂包括第一伸缩节和第二伸缩节,第一伸缩节与车体连接作为起重机的顶升套架,第二伸缩节插设在第一伸缩节内并与其伸缩配合,第二伸缩节的下面布置一套提升架,与第一伸缩节间通过钢丝绳滑轮组相连;第一伸缩节的底部设有标准节导引门,用于加节的标准节从标准节导引门进入第一伸缩节,然后与第二伸缩节连接完成标准节的增加。本发明便捷高效,打破了伸缩桁架结构应用的弊端,提高了市场适用性,满足一般市场吊装重量和高度的需求,当更高的吊装物需求时,通过加节实现增高。
