Description

Technical Field

[0002] Platform doors are commonly used in subway platforms, intercity platforms and train platforms, and can also be used in other similar platform engineering scenarios to keep the doors closed before the train stops and opens, isolating passengers on the platform to prevent them from falling off the platform and onto the track. With the increasing popularity of prefabricated station buildings, the advantages of modular platform door installation solutions with high assembly efficiency are becoming more and more prominent, and the industry's acceptance is getting higher and higher. The modular installation of platform doors has become an irreversible trend in the rail transit industry.

[0003] At present, when installing the upper steel structure of the platform door, the upper part of the column and the civil engineering beam are fixed by connecting parts such as L-shaped bending parts, and multiple waist holes in different directions are opened on the connecting parts to achieve three-dimensional adjustment of the column during installation to adapt to civil engineering deviations and measurement deviations. However, opening more waist holes will cause the connecting parts to be larger in size, increase in weight, and increase the difficulty of assembly. In addition, the three-dimensional adjustment range is limited by the size range of the waist holes, and the adjustment range is small. If the deviation of the civil engineering beam is too large, it is necessary to redesign specific connecting parts. The existing connecting parts do not meet the needs of modular installation.
