Abstract

The invention provides a crane, a standard knot lifting and adding system thereof and a standard knot lifting and adding method. The standard knot lifting and adding system includes a climbing frame, the climbing frame is used for sleeving the crane tower body, the standard knot lifting and adding system also includes a lifting device, the lifting device comprises: a fixed cross beam, a piston cylinder and a movable cross beam, the fixed cross beam is arranged on the climbing frame, the fixed cross beam is provided with a first connecting structure used for in detachable connection with the crane tower body, the lower end of the piston cylinder is connected with the fixed cross beam, the movable cross beam is connected with the upper end of the piston cylinder, and the movable cross beam is provided with a second connecting structure used for in detachable connection with the crane tower body. The technical scheme of the crane can improve force conditions of the standard knot lifting and adding system in an installation process and improve the installation efficiency.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a crane and its standard section lifting and adding system, and a standard section lifting and adding method. Background technique [0002] When the crane erects the tower, a certain number of standard sections need to be assembled sequentially from bottom to top to form the tower body. During the assembly process, the standard section lifting and adding system needs to be used to introduce the standard sections to be installed. Such as Figures 1 to 4 , shows a partial schematic view of the tower body 20', which includes three standard sections 21' stacked up and down, the top of the uppermost standard section 21' is detachably connected to the superstructure 10', and the superstructure 10' includes The lower support, slewing support and upper support, the standard section lifting and adding joint system includes a climbing frame 30' and a jacking device 40', wherein the cli...
