The invention discloses an auxiliary platform for quickly disassembling and assembling a cantilever crane. Belongs to the field of crawler crane hoisting, after the platform is assembled to a working state, two sectors A and B of a to-be-assembled boom are respectively placed on brackets of a fixed support I and a sliding support, the sector B is pushed to move along a track, and meanwhile, angles of all web members on a boom section are correspondingly followed, so that the cross section is enlarged; afterwards, the remaining required web members and parts are assembled; when the cantilever crane is converted from the working state to the transportation state, the process of reducing the section of the cantilever crane is opposite to the process; according to the invention, the problems that the required condition requirement is high when the variable-section arm section is disassembled and assembled, and the difficulty is high when hoisting and all joints are aligned are solved; working and storage states are switched through disassembly and assembly of the connecting rod, and convenience and rapidness are achieved. In addition, modular design is adopted, the whole platform is divided into a plurality of detachable modules, and each module can be designed to be in a folding or telescopic mode at the same time; the device is easy to operate, convenient and fast, high in safety and convenient to transport and store.

    本发明公开了一种臂架快速拆装辅助平台。属于履带式起重机吊装领域,将本平台装配至工作状态后,先将待装配臂架的两个扇面A与B分别放置于固定支座一和滑动支座的托架上,推动扇面B沿轨道移动,同时臂节上所有腹杆角度相应随动,实现截面的变大,随后装配剩余所需腹杆及零部件;臂架由工作状态转变为运输状态时,臂架截面变小的过程同上述过程相反;本发明解决了可变截面臂节拆装时所需条件要求较高,在吊装和各接头对齐时难度较大的问题;通过连杆的拆装切换工作与存放状态,方便快捷;另外,采用模块化设计,将平台整体分为可拆卸的多个模块,每个模块同时可设计为折叠或伸缩形式;本发明操作简单、方便快捷、安全性高,且方便运输与存放。
