Abstract
The invention discloses a nylon steel rail insulation section, relating to the technical field of steel rail insulation sections.
Description
Technical Field
The invention relates to the technical field of steel rail insulation sections, in particular to a nylon steel rail insulation section.
Background
The insulation of the section of the steel rail is an important component of a track circuit, and once the insulation is damaged, the normal transmission of signals is influenced, and even the driving safety is endangered. The main reason for the insulation damage of the steel rail section is that the insulation performance is reduced due to the influence of the environment and the temperature change, and in addition, the steel rail section insulation bears the same complex mechanical forces of compression, impact and the like as the steel rail, the steel rail is longitudinally and vertically horizontally worn, and the steel rail section insulation is easily damaged by an external force.
At present, the rail that adopts is insulating more for engineering plastics pottery section rail, and the insulating impact resistance of engineering plastics pottery section rail, the compressive force ability is very poor, receive weather temperature change's influence and rail face impact force, the compressive force influence, because metallurgical vehicle is mostly the heavy truck, the crowded dead and cracked phenomenon of rail insulation fracture frequently appears in the driving in-process, often it is today to change the situation of separating day with regard to damage, the total 1200 departments rail in northeast region is insulating, there is the crowded dead "red light area" that leads to the fact of frequent rail insulation of 100 departments in summer, personnel's repair time in summer has mostly consumed on changing the rail is insulating. The insulating damage of rail section is serious, very big increase maintainer's intensity of labour, and the track circuit trouble and the track circuit hidden danger that produce have greatly influenced railway transportation efficiency and safe transportation production.
Disclosure of Invention
The invention aims to: the invention provides a nylon steel rail insulation section, aiming at solving the technical problem that the insulation of the steel rail section in the prior art is easy to damage.
The invention specifically adopts the following technical scheme for realizing the purpose:
the insulating section of nylon steel rail is made of nylon material, and has holes and ceramic beads fixed inside the holes.
Furthermore, a plurality of holes are formed in the insulating section of the steel rail, and each hole is internally provided with a ceramic bead.
Furthermore, the connection mode of the ceramic beads and the insulating section of the steel rail is bonding.
Furthermore, the bonding medium between the ceramic beads and the insulating section of the steel rail is hot melt adhesive.
Further, the ceramic beads are obtained in the following manner: recovering the existing engineering plastic-ceramic section insulation, and then taking out the ceramic beads in the plastic-ceramic section insulation
The invention has the following beneficial effects:
1. through the innovation to the rail section is insulating, reduce "red light area" because of the damaged track insulation causes, greatly reduced the fault rate of track circuit, improved insulating performance of rail section and insulating life cycle of rail section.
2. Through the innovation to the rail section is insulating, improved maintainer's maintenance efficiency, reduced maintainer's intensity of labour, practiced thrift manpower resources's waste to a certain extent.
3. The innovation of the invention is based on the principle of old material utilization and waste material utilization, and the activity is completed by utilizing old materials and waste materials on the basis of not increasing the maintenance cost, thereby reducing the maintenance cost, protecting the regional environment and achieving three purposes at one stroke. If the innovation result can be used for a long time, the cost for maintaining the track circuit can be greatly reduced.
Detailed Description
In order that those skilled in the art will better understand the present invention, the following examples are provided to illustrate the present invention in further detail.
Example 1
The embodiment provides an insulating section of nylon rail, sets up the material of the insulating section of current rail into nylon to set up the hole on the insulating section of rail, and at the downthehole fixed ceramic pearl that sets up.
Furthermore, a plurality of holes are formed in the insulating section of the steel rail, and each hole is internally provided with a ceramic bead.
Furthermore, the connection mode of the ceramic beads and the insulating section of the steel rail is bonding.
Furthermore, the bonding medium between the ceramic beads and the insulating section of the steel rail is hot melt adhesive.
Further, the ceramic beads are obtained in the following manner: recovering the existing engineering plastic-ceramic section insulation, and then taking out the ceramic beads in the plastic-ceramic section insulation
Example 2
The technology of this patent verifies the analysis:
1. and (3) field investigation: the common point of the insulation damage of the plastic ceramic section steel rail is that the plastic is damaged, and the ceramic beads inside the plastic ceramic section steel rail can be intact; the section of the steel rail made of nylon is insulated, and no fracture is found, but the pulverization is serious due to the extrusion of the rail end of the steel rail.
2. Reason analysis: the plastic ceramic is insulating and extrusion-resistant, and is easy to crack in winter; the nylon material has high insulation toughness and is not resistant to extrusion. If the advantages of the two materials are combined, the phenomena of brittleness and aging caused by the change of air temperature environment can be solved, and the impact force and the compression force generated by locomotives and vehicles can be enhanced.
3. Research and preparation: the engineering plastic ceramic section insulation is recovered on site, ceramic beads in the plastic ceramic section insulation are taken out, the nylon section insulation with better quality is achieved, holes are formed in different bearing points of the bearing force of the steel rail according to the insulation sheet, the recovered ceramic beads are filled in the holes formed in the nylon section insulation, and the holes are integrally fixed in a hot melt adhesive mode.
4. And (3) field test: and (3) carrying out a rail mounting test on the modified nylon section insulation, recording the service cycle and the maximum service life of the modified nylon section insulation, and finding that the service cycle of the steel rail section insulation is obviously prolonged through the field rail mounting test. The service life of the rail section insulation before the reconstruction is 3-5 working days on average, and the service life of the rail section insulation after the reconstruction is 70 working days on average, so that the service life of the rail section insulation is greatly prolonged.
The above description is only a preferred embodiment of the present invention, and not intended to limit the present invention, and the scope of the present invention is defined by the appended claims, and all changes that come within the meaning and range of equivalency of the specification are therefore intended to be embraced therein.
