Embodiment Construction

[0014] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0015] refer to figure 2 , The tower top assembly of the tower crane of the present invention includes: a tower top 201 and a standard section 202 connected to the bottom of the tower top 201, wherein the tower top 201 and the standard section 202 are welded as one.

[0016] In the present invention, the tower top 201 and the standard section 202 are connected by welding, replacing the original two parts connected by a pin shaft to form a whole, reducing the link of pin shaft installation in the installation process, and avoiding the phenomenon of pin hole wear. Use reliability is stronger.

[0017] As a preferred solution, a rib plate 203 is welded between the tower top 201 and the standard section 202 to strengthen the strength of the connection between the tower top 201 and the standard section 202 and ensure the stability of the tow...

Abstract

The invention discloses a tower top assembly of a tower crane. The tower top assembly comprises a tower top and a standard knot connected with the bottom of the tower top, and is characterized in that the tower top and the standard knot are welded into a whole, and a ladder is arranged at the side of the tower top in a welding way; and a plurality of fences which are arranged at intervals are arranged at the side of the ladder in a welding way. The tower top assembly provided by the invention has the advantages that the tower top and the standard knot are welded into a whole instead of originally connecting the two parts into a whole by pin shafts, so that the link of pin shaft installation in the installation process is reduced, the phenomenon of pin hole wear is better avoided, and the service reliability is stronger; and the fences at the side of the ladder are arranged at intervals to play a protective role and also reduce the overall weight of the tower crane.

Description

technical field [0001] The invention relates to a component, in particular to a tower top component of a tower crane, which belongs to the field of crane manufacturing. Background technique [0002] refer to figure 1 , the tower top assembly of the tower crane includes: a tower top 101, and a standard section 102 connected to the bottom of the tower top 101. In the existing tower top assembly of tower cranes, pin holes 103 are formed at the connection between the tower top 101 and the standard section 102, and the two are connected as a whole through the pin shaft passing through the pin holes, which adds a During the on-site installation, in addition, during use, the pin holes are prone to wear and tear, which not only affects the normal operation of the tower crane, but also poses certain safety hazards. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the purpose of the present invention is to provide a tower crane tower top asse...
