Tower crane standard section stable and firm in connection

Abstract

The invention discloses a tower crane standard section stable and firm in connection. The tower crane standard section comprises main chord members, diagonal web members and transverse web members. The number of the main chord members is four sets, the four sets of main chord members are distributed in a rectangular shape, the ends of the adjacent main chord members are connected through the transverse web members, the diagonal web members are arranged between the adjacent main chord members, and diagonal cross beams are arranged on the main chord members located at the diagonal corners. An escalator is installed on the diagonal cross beams, and a safety rope connecting assembly is installed on the escalator. Tower crane standard sections are connected through fixing structures and reinforcing assemblies, the fixing structures are used for connecting the main chord members at the upper position and the lower position, the reinforcing assemblies are used for connecting the transverse web members at the upper and lower adjacent positions, and connecting corner plates are arranged at the upper ends and the lower ends of the main chord members. According to the tower crane standard section, tower crane standard sections which are arranged up and down are connected through the fixing structures and the reinforcing assemblies, so that double reinforcing measures are taken for connection between the tower crane standard sections, connection between the tower crane standard sections is more stable and firmer, and the overall safety is improved.

Description

technical field [0001] The invention relates to the technical field of tower crane parts, in particular to a tower crane standard joint with stable and reliable connections. Background technique [0002] Tower crane is the most commonly used lifting equipment on construction sites, also known as "tower crane". , concrete, steel pipe and other construction raw materials. Tower crane is an indispensable equipment on the construction site. Tower crane standard section plays an important role in cranes, tower cranes, tower cranes, elevators and other mechanical equipment. A good standard joint can not only improve the stability of these heavy machines, but also improve the safety performance, flexibility and work efficiency of the whole machine. [0003] The existing tower crane standard sections are mainly connected by the bolts between the main chords during installation, so that the connection measures are single, and the connected bolts are prone to fall off when they are...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a tower crane standard section with stable and reliable connection, so as to solve the problem that the existing tower crane standard section in the above background technology is mainly connected by the bolts between the main chords, so that the connection measures are single , and the bolts after the connection are easy to fall off when they are used for a long time, which makes the stability and safety of the standard section of the tower crane low after connection
