The invention discloses a tower crane climbing frame, relates to the technical field of tower cranes. The tower crane climbing frame comprises a leading-in surface, a climbing surface opposite to the leading-in surface, and two connecting surfaces connected between the leading-in surface and the climbing surface; the leading-in surface, the climbing surface and the two connecting surfaces are connected together through main chord members of the climbing frame to form a frame structure with a quadrangular cross section, and a leading-in platform is hinged to one side of the leading-in surface and is connected to the first main chord member through a steel rope; a plurality of rollers for driving standard knots to move towards the interior of the climbing frame are arranged on the leading-in platform, the rollers are rotationally connected to the side wall of the leading-in platform, the connecting line of the axes of the rollers inclines towards one side of the leading-in surface, and the roller far away from one end of the leading-in surface is located at the high end. Movement of the standard knots is achieved through the rollers obliquely arranged on the leading-in platform, the standard knots do not need to be disassembled in the mounting process, the mounting time of the standard knots is shortened, and the difficulty is lowered.
本申请公开了塔式起重机技术领域中的一种塔机爬升架,爬升架包括引进面、与引进面相对的爬升面、以及连接在引进面与爬升面之间的两个连接面,其中引进面、爬升面及两个连接面之间通过爬升架的主弦杆连接在一起形成横截面为四边形的框架结构,引进面一侧铰接有引进平台,引进平台通过钢绳连接在第一主弦杆上,引进平台上设置有多根带动标准节朝向爬升架内部移动的辊筒,多根辊筒转动连接在引进平台的侧壁上,多根辊筒轴心的连线朝向引进面一侧倾斜,其中远离引进面一端的辊筒处于高端。本申请标准节的移动是依靠引进平台上的倾斜设置的辊筒来实现,在标准节安装的过程中无需拆卸,减少了标准节安装的时间并降低了难度。
