AI Technical Summary

Technical Problem

Traditional catenary supports are prone to loosening under vibration and impact loads, and their simple design makes them difficult to adapt to changes in different environments and load conditions, increasing maintenance frequency and safety hazards.

Method used

The fixed base is composed of two U-shaped rods arranged in opposite directions. It is combined with components such as connecting blocks, buckles, connecting columns and support rods, and assembled by means of snapping, bolt connection and other methods. The internal ring plate, spring and screw are set to form an anti-loosening structure and provide pre-tightening force to improve stability.

Benefits of technology

It improves load-bearing capacity, enhances resistance to vibration, ensures long-term stability and reliability of the support, simplifies the installation process, and reduces maintenance frequency.

Abstract

The utility model relates to the technical field of railway contact networks, in particular to a railway contact network carrier cable support. The support comprises a fixed seat, a connecting block, a bottom plate, a buckle, a connecting column and a supporting rod. The fixed seat is formed by connecting two U-shaped rods which are arranged oppositely, and a vertical penetrating space is formed between the U-shaped rods; the bottom of the connecting block is provided with a clamping part clamped with the fixed seat, and the top is provided with a clamping assembly; the bottom plate is fixed to the fixing base through bolts. The buckle is clamped above the fixed seat, and a mounting hole is formed in the buckle; the connecting column is a hollow column body, an annular piece, a spring and a screw rod are arranged in the connecting column, and the screw rod is connected with the buckle; an annular structure is arranged at the end of the supporting rod and used for containing the carrier cable. The design structure is reasonable, installation is convenient and fast, stability is high, stress can be effectively dispersed, the bearing capacity is improved, the anti-vibration capacity is enhanced through pre-tightening force, and the device is suitable for supporting and protecting the railway contact net carrier cable.
