The beneficial effect that this scheme produced is:
The first transition beam and the second transition beam are fixed together through the matching of the bolts and the nuts to form a transition beam structure, and the length between the first transition beam and the second transition beam can be adjusted for different types of tower cranes, so that the transition beam structure can adapt to the tower cranes of different types, and the production and manufacturing cost is reduced.
Further, a through groove is formed in the connecting portion, and the through groove horizontally penetrates through the connecting portion. During installation, a worker can hold the first transition beam and the second transition beam through medulla Tetrapanacis, so that the stability of the first transition beam and the second transition beam is kept, and the installation is facilitated.
Further, a support bar is fixedly installed between the main beam and the connecting portion. The installation of bracing piece can strengthen the stability between girder and the connecting portion.
Further, protective layers are arranged on the outer walls of the transition beam structure and the introduction system. Because the working environment of the tower crane is severe, the transition beam structure and the introduction cross beam are easy to corrode and abrade, the safety performance is easy to drop, the safety accident is caused, and the service life of the transition beam structure and the introduction system can be prolonged due to the arrangement of the protection layer.
Further, a washer is provided between each two nuts on the bolt. The arrangement of the gasket can enhance the connection tightness between the bolt and the nut, prevent loosening, reduce the abrasion between the bolt and the nut, and increase the contact area between the bolt and the nut, thereby improving the stability.
Furthermore, the introducing cross beam comprises two cross beams which are arranged in parallel, and a connecting rod is fixedly arranged between the two cross beams fixedly arranged at the bottom of the transition beam structure. The setting of connecting rod fixes distance, position etc. between two crossbeams, guarantees the stability of introducing the crossbeam.
