The invention relates to the technical field of cranes, in particular to a liftable tower crane and a lifting regulation and control method thereof, and solves the technical problems that a tower body is mounted layer by layer when the tower crane in the prior art is used, the overall height of the tower crane can only be regulated by mounting the tower body, and the tower crane is inconvenient to use. And therefore, the working difficulty and the use convenience of the tower crane are greatly improved. The liftable tower crane comprises a base, the bottom of the base is fixedly connected with a bearing frame, the inner side of the bearing frame is slidably connected with a bearing plate, the top of the bearing plate is provided with a tower body, and the top end of the tower body is provided with a cargo boom. According to the mode provided by the invention, the lifting adjustment of the tower body can be realized through the bearing frame and the components thereof, and the stability of the tower body can be greatly improved by utilizing the bottom frame, the components and the bearing pipe.
本发明涉及起重机技术领域,尤其涉及一种可升降式塔式起重机及其升降调控方法,解决了现有技术中的塔式起重机在进行时使用时,都是通过一层一层的将塔身进行安装的,在需要对塔吊整体的高度进行调节时只能通过安装塔身实现,进而大大增加了塔式起重机的工作难度以及使用的便捷性的问题。一种可升降式塔式起重机及其升降调控方法,包括底座,底座的底部固定连接有承载框,且承载框的内侧滑动连接有承载板,承载板的顶部安装有塔身,且塔身的顶端安装有起重臂。本发明中提出的方式,通过承载框及其组件可以实现塔身的升降调节,并且利用底框以及部件以及承载管可以大大提高塔身的稳定性。
