Tower crane and switch base thereof

Abstract

The invention discloses a tower crane and a switch base thereof. The switch base comprises a connection seat, four box-shaped beam assemblies and four connecting rods; each box-shaped beam assembly comprises a box-shaped beam, a first connecting piece and a second connecting piece; a first end of each first connecting piece is fixedly connected with the first outer wall of the corresponding box-shaped beam; the second end of each first connecting piece is connected with the standard knot of the tower crane in a detachable manner; a first end of each second connecting piece is fixedly connected with the second outer wall, opposite to the corresponding the first outer wall, of the corresponding box-shaped beam; the second end of each second connecting piece is connected with a third connecting piece in a tower crane foundation in a detachable manner; the first ends of the four box-shaped beams in the four box-shaped beam assemblies are all connected with the connection seat in a detachable manner; the four connecting rods are connected between the second ends of the adjacent box-shaped beams in a detachable manner. The switch base of the tower crane is suitable for different types of tower cranes, can enable the standard knots of different types of tower cranes to be mounted on the same tower crane foundation through the switch bases adaptive to the standard knots, has a simple structure and is easy to mount and dismount.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a tower crane and a conversion base thereof. Background technique [0002] Tower crane, that is, tower crane, is a kind of lifting equipment used in building construction. The tower crane generally includes the tower crane foundation, the connection base installed on the tower crane foundation and the standard section installed on the connection base. Since the tower crane foundation plays the role of fixing the entire tower crane, the tower crane foundation determines the working process of the tower crane. safety performance in . At present, generally according to the use requirements of the tower crane, the tower crane foundation is made into a concrete foundation or a lattice column steel platform foundation. The construction process of the above two tower crane foundations is relatively complicated and difficult to construct. [0003] During the construction process of...

AI Technical Summary

Problems solved by technology

The combined base can be connected with different types of tower cranes by adjusting the position of the sliding support, but because the combined base and the foundation of the tower crane are fixedly connected, it cannot be adjusted according to different tower crane models The matching connecting base will inevitably limit the selection range of the tower crane; taking a step back, even if the combined base and the foundation of the tower crane are detachably connected, the above-mentioned complex structure and cumbersome installation process will not Suitable for repeated disassembly and installation, this process will inevitably result in a waste of manpower and material resources and prolong the construction period
