The structure of connecting the plug pins and the steel wire rope is adopted, and the steel wire rope is connected with the connecting plug pins, therefore the connecting strength of the steel wire rope can be increased, at the same time, the steel wire rope is durable, and the anti-corrosion performance of the steel wire rope is better than that of the normal iron wire, in addition, the length of the steel wire rope can be selected at will, the price is relatively low, and the connecting line is suitable for the on-site use of the metallurgical enterprises. The steel wire rope can adopt the marine steel wire rope, which has a better anti-corrosion performance. The plug pins can be divided into two types, which can be used to satisfy different connecting requirements, therefore a lead-in wire and a jumper can be formed, and different signal transmission requirements can be satisfied.

Description

Connecting wires for railway signal transmission

technical field

The utility model relates to a signal connecting wire, in particular to a connecting wire used for railway signal transmission.

Background technique

The lead-in wires and jumper wires used in traditional railway signals use multi-strand ordinary iron wires. These ordinary iron wires are directly connected to the rails. Since the lead-in wires and jumper wires are located outdoors, they are greatly affected by the outside world, and their connections are easily corroded. The service life is not long, and after the line is broken, it will affect the normal railway transportation. If a special anti-corrosion line is used, the price is expensive, and because the metallurgical railway line changes greatly, after the line change, a large number of lead-in lines and jumper lines need to be replaced. If the anti-corrosion line is used, it will inevitably increase the cost, so the anti-corrosion line has not been widely promoted on site.

Utility model content

The technical problem to be solved by the utility model is to provide a connection line for railway signal transmission with improved service life.

The utility model solves the technical problem and adopts the connecting wire used for railway signal transmission, which includes a steel wire rope and two connecting plug nails. The connecting plug nails include a steel wire connecting end and an installation end. The two connecting plugs are nailed, and the ends of the steel wire ropes are connected to the connecting ends of the steel wires.

Further, the connecting end of the steel wire is provided with a connecting through hole, and the end of the steel wire rope is welded in the connecting through hole.

Further, the steel wire rope is a marine steel wire rope.

Further, the connecting plugs are divided into two types, which are respectively called conical plugs and screw plugs; the installation end of the conical plug is tapered; the installation end of the screw plug is screw-shaped .

The beneficial effects of the utility model are: due to the structure of the connecting plug nail and the steel wire rope, the steel wire rope is connected to the connecting plug nail, so that the connection strength of the steel wire rope can be increased. The length can also be selected arbitrarily, and the price is relatively economical, which is very suitable for on-site use in metallurgical enterprises. The steel wire rope can be a marine steel wire rope, which is more corrosion-resistant. Connecting plugs can be divided into two types, respectively adapted to different connection requirements, thus forming lead-in wires and jumper wires to meet different signal transmission requirements.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figures 1 and 2, the utility model includes a steel wire rope 1 and two connecting plugs 2, the connecting plug 2 includes a steel wire connection end 4 and an installation end 5, and the two ends of the steel wire rope 1 are respectively connected to two On a connecting plug nail 2, the end of the steel wire rope 1 is connected to the steel wire connecting end 4. The length of the wire rope 1 depends on the site conditions. After selecting the wire rope 1 of suitable length, the two ends of the wire rope 1 are welded on the two connecting plugs 2, and then the connecting plugs 2 are used to install the entire connecting wire. Mounting is done by connecting plugs 2, which increases the flexibility of mounting. The steel wire rope 1 can adopt 11mm marine steel wire rope, and the marine steel wire rope has strong corrosion resistance, which increases the service life of the whole connecting wire.

Specifically, as shown in FIG. 3 and FIG. 4 , the connection end 4 of the steel wire is provided with a connection through hole 3 , and the end of the steel wire rope 1 is welded in the connection through hole 3 . The steel wire rope 1 can be directly penetrated into the connection through hole 3 for welding to increase the connection strength.

Specifically, as shown in Fig. 3 and Fig. 4, the connecting plug 2 is divided into two types, which are respectively called a tapered plug and a screw plug; the mounting end 5 of the tapered plug is tapered; the The mounting end 5 of the screw plug is screw-shaped. At this time, different types of tapered plug screws can be selected according to different installation needs. For example, when it is necessary to make a railway signal lead-in line, the embodiment shown in FIG. 1 can be adopted, and the two ends of the steel wire rope 1 are respectively connected with a tapered plug and a screw plug. When it is necessary to make a railway signal jumper, the embodiment shown in FIG. 2 can be adopted, and both ends of the steel wire rope 1 are connected with tapered plugs.
