Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of signal cable splicing, more particularly to a railway signal cable splicing fixing support. BACKGROUND

[0002] Railway operation cannot be separated from railway signal cables. A large number of railway signal cables are installed in the cement cable trench along the railway line for use, which plays a protective cable function, facilitates maintenance, and ensures railway safety. However, after a period of use, the cable lines along the railway will inevitably be damaged and need to be maintained and processed. The two cable lines need to be spliced and processed, and a fusion splicing machine is used to fuse and connect the joint parts of the two cable lines. The fusion splicing machine is generally placed on the bottom surface of the cement cable trench after installation. However, when the train passes, it will cause vibration to the cable lines along the line, causing the cable lines to be dragged, which can easily cause the fusion joint to be damaged again. In view of this, we propose a railway signal cable splicing fixing support. CONTENT OF THE INVENTION
