Abstract

The present invention relates to a railway signal cable emergency repair device, which provides a railway signal cable emergency device ensuring continuous operation, simple and convenient manipulation of railway signal cables free from environmental impact and comprises a flexible cable, a quick joint at both ends of the flexible cable and a tightening device arranged on the quick joint and connected with the railway signal cable. The flexible cable is composed of a plurality of cable cores centrally arranged in the cable. A flexible coupler is positioned at center of the quick joint and composed of a rubber elastomer, an embedded part with a groove in the rubber elastomer and a flexible coupling body positioned in the embedded part and connected with the cable core. The flexible coupling body is provided with a partially inwards concave bottleneck. An opening end of the flexible elastomer is arranged into the groove of the embedded part.

Description

technical field [0001] The utility model relates to an emergency repair device for railway signal cables. Background technique [0002] The railway signal cables laid in parallel along the entire length of the railway track line are mainly responsible for the transmission of information such as track circuits and lighting to control the operation of trains. Due to construction, disasters and other reasons, sometimes the signal cable is interrupted. Once the railway signal cable is interrupted, it will immediately cause accidents such as train parking or endangering traffic safety. [0003] Existing various types of railway signal cables, including railway digital signal cables, inner shielded signal cables, railway axle counting signal cables, comprehensive shielded signal cables, etc. are generally designed for direct buried underground fixed laying, and the outside of the cable is usually wrapped with an aluminum sheath , armored steel tape and other shielding layers, and...
