The invention discloses a cantilever crane telescopic tower crane with an attachment mechanism and a working method thereof, and belongs to the technical field of tower cranes of building machinery. The cantilever crane telescopic tower crane comprises a mounting base, a jacking hydraulic pump station, a climbing frame, a main arm, a main arm attachment mechanism, a cantilever crane main winch anda balance weight; the main arm attachment mechanism is used for assisting stabilization of the main arm through a building under construction; the cantilever crane is telescopic; an inhaul cable withone end connected with the telescopic cantilever crane is arranged on the telescopic cantilever crane; the other end of the inhaul cable is hinged to an inhaul cable winch arranged on the rear of thetelescopic cantilever crane through a main arm top bracket and provides pulling force; the inhaul cable tensions the telescopic cantilever crane, and stress borne by the telescopic cantilever crane is reduced. The cantilever crane telescopic tower crane can reduce the length of the cantilever crane and is suitable for operation in a narrow space. The main arm attachment mechanism achieves auxiliary supporting to the main arm, the main arm is prevented from overturning, the overturning moment of the main arm is reduced, the auxiliary mechanism and the main arm can move relatively in the vertical direction, the gravity of the main arm is prevented from acting on an attached object, and damage to an attached building is reduced.

    一种带有附着机构的臂架可伸缩塔机及其工作方法,属于建筑机械的塔机技术领域。包括安装底座、顶升液压泵站、爬升架、主臂、主臂附着机构、臂架主卷扬和配重,利用主臂附着机构通过施工中的建筑物辅助主臂的稳定;臂架为可伸缩臂架、可伸缩臂架上设有一端与可伸缩臂架连接的拉索,拉索的另一端通过主臂顶部支架与设置在可伸缩臂架后方的拉索卷扬相互铰接并提供拉力,拉索对伸缩臂架进行拉紧,减少伸缩臂架承受的应力。可以减小臂架长度,适合在狭小空间内作业。主臂附着机构实现对主臂的辅助支撑,避免主臂倾覆,减小主臂的倾覆力矩,辅助机构与主臂垂直方向上能够相对运动,避免了主臂的重力作用在附着物体上,减少对被附着建筑物的损害。
