Description

Technical Field

[0001] This utility model belongs to the field of cable laying technology, and in particular relates to a cable laying device for traction substations. Background Technology

[0002] Traction substations convert electrical energy from the regional power system into power suitable for electric traction, based on the different current and voltage requirements of electric traction. This power is then delivered to the overhead contact line along the railway line to supply power to the electric locomotives. Traction substations often construct temporary lines. If the temporary cables are long, their laying direction needs to be adjusted according to the site layout, equipment location, and routing requirements.

[0003] However, traditional cable laying devices typically employ fixed installation structures, such as anti-eddy current cable clamps or cable fixing clips. Anti-eddy current cable clamps consist of a bracket, cable clamp blocks, and screws, but the position and angle of the cable clamp blocks are not adjustable. Cable fixing clips secure the cable in any position, protecting it from external forces and preventing loosening and vibration. However, they cannot accommodate position adjustments or bends. Guide wheels are then needed at cable bends. These guide wheels are primarily used to change the cable's transmission direction during laying to meet different requirements. Therefore, they have low adaptability in complex wiring environments. When cables need to be turned, guide wheels are required, increasing construction time and potentially affecting cable safety and reliability due to inaccurate installation, thus exhibiting certain limitations.

[0004] Therefore, there is an urgent need for a simple and reasonably designed cable laying device for traction substations that can adjust the spacing between adjacent cable clamps and allow for forward and backward cable routing to adapt to different cable turning directions and meet the temporary wiring needs of traction substations.
