Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrified railway technology, specifically to a shoulder frame for the external AF line of a railway tunnel. Background Technology
[0002] The AF line shoulder is an important component of the railway catenary system, mainly used to support and fix the auxiliary line (AF line) to ensure its safe and stable operation.
[0003] The AF line shoulder frame is installed on steel supports on both sides of the track. H-beam steel columns are commonly used as the external steel supports in the tunnel, and their main characteristics are as follows: (1) Installation location: Determined by the overall cable routing height, it is usually installed on the top or side of an H-beam column, at a different location from the protective wire (PW line) shoulder frame to ensure a safe distance for the cable. (2) Structural features: AF line shoulder frame is usually welded, for example, the shoulder frame steel is welded together, and a hanging component is added at an appropriate position. The component is connected to one end of the insulator.
[0004] The AF line shoulder frame and H-beam steel column are connected using bolt assemblies. For example, connection holes are pre-drilled in the bottom plate of the shoulder frame connection end, and connection holes are pre-drilled in the column surface of the H-beam steel flange plate. Matching hole positions are then used for fastener connection. (3) Function: The positive feeder is fixed on the steel column by the shoulder frame to ensure the stability and safety of the traction power supply system.

Therefore, fasteners need to be completely replaced after a certain number of years of use. Replacement requires live-line work, must be carried out in sections, has a long cycle, high cost, and high risk. Utility Model Content
