Description

Technical Field

[0001] The utility model relates to the technical field of subway rigid contact networks, and more specifically to a pre-buried structure for installing subway rigid contact networks. Background Art

[0002] The contact network is installed in a zigzag shape above the rails on electrified railways. The subway rigid contact network requires an embedded structure during installation. However, the commonly used embedded structures are mostly fixed with bolts during installation, which is cumbersome and time-consuming. In addition, the adjustment range of the embedded structure is limited, which reduces the convenience of use.

[0003] For example, announcement number CN219789952U discloses a pre-buried structure for installing a rigid contact network of a subway, which includes two pre-buried connecting beams and pre-buried columns fixedly installed at both ends of the pre-buried connecting beams.

[0004] It can be seen from the above-mentioned public solution that the distance between the two longitudinal connecting arms cannot be adjusted, and the adjustment range of the distance between the adjusting screws is small, which brings inconvenience to use. In addition, the embedded connecting beams, embedded columns, longitudinal connecting arms and sliding angle seats are positioned by bolts and other components, and the installation is cumbersome and time-consuming, which reduces the assembly efficiency.
