Description

Technical Field

[0001] The utility model belongs to the technical field of cables, and in particular relates to an armored railway signal cable. Background Art

[0002] Armored railway signal cable is a cable used for railway signal transmission and control system. A layer of bendable steel belt or steel wire is added inside the outer sheath of the cable to increase the mechanical strength of the cable and improve the corrosion resistance of the cable. It is specially designed for areas that are extremely vulnerable to external damage and corrosion.

[0003] At present, when laying long distance railway cables, it is inevitable to encounter some undulating terrain sections, and the cables need to be suspended for installation. However, since the cables have armored metal layers, the weight of the cables increases, which easily causes the suspended parts to fall, affecting the installation stability of the suspended parts, which is not conducive to the long-term stable use of the cables.

[0004] In order to solve the above problems, an armored railway signal cable is proposed in the present application. Utility Model Content

[0005] The purpose of the utility model is to provide an armored railway signal cable, which solves the problems raised in the above background technology.

[0008] Furthermore, a positioning groove for passing the steel wire rope is provided inside the positioning belt, a clamp seat is provided inside the positioning belt, and a limiting belt for being sleeved on the outside of the steel wire rope to form a suspension is provided inside the clamp seat.

[0009] Furthermore, a cover plate is arranged above the clamp seat, and a plug for fixing the limiting belt is arranged at the lower end of the cover plate.

[0010] Furthermore, the interior of the positioning band is also used to open a groove to install the plug and the limiting band.

[0011] Furthermore, a storage groove for installing a positioning belt is provided above the protective belt.

[0012] Furthermore, clamping columns are provided on both sides of the plug column for penetrating the limiting belt and connecting and fixing the clamping seat.

[0013] Furthermore, the sealing mechanisms at both ends of the plug are used to fill the upper opening of the positioning groove to form a seal to prevent rainwater from entering.

[0014] The utility model has the following beneficial effects:

[0015] The utility model adds a protective belt on the outside of the signal cable core, and the steel wire rope can replace the signal cable core to withstand external pulling, so that the cable does not need to withstand a large amount of external force when hanging, avoiding extrusion deformation and rupture, etc., and ensuring the service life and stability of the cable. Secondly, the hanging position is adjustable, and the installation can be completed without adding external clamps to squeeze the cable, thereby improving work efficiency and applicability to different environments;

[0016] After the armored metal layer is wrapped, the utility model directly lays the protective belt above it and performs the extrusion operation together.
