Description

Technical Field

[0001] The utility model relates to the technical field of cable fixing equipment, in particular to a cable fixing device for a railway station building. Background Art

[0002] With the increase in population, the number of people traveling during holidays has also begun to increase significantly. In order to adapt to the increase in the number of travelers, double-decker railway stations have been built in many places. As one of the most important transportation hubs in a city, electricity is an important construction content that cannot be ignored during the construction process. In double-decker railway stations, most of them are buried in the wall. Although this method is beneficial to appearance, when the line fails, the wall needs to be destroyed to maintain the cables inside, which not only greatly consumes the time and energy of the staff, but also seriously affects the normal operation of the railway station due to the need to cut off power when repairing the cables, bringing great inconvenience to people. However, if the cable is exposed to the outside, the cable will oxidize, which will aggravate the aging of the cable and reduce the service life of the cable. In view of this, we propose a cable fixing device for railway station buildings. Utility Model Content
