Description
Technical Field
The invention relates to the technical field of rail electricity, in particular to a method for reconstructing section insulation of a steel rail.
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 for engineering plastics pottery section rail, the impact resistance, the compressive force ability is very poor, receive weather temperature variation'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, the situation of change second day with regard to damage often appears, especially the damage rate in summer is higher, the crowded damage in many places of rail insulation leads to the fact "red light area", personnel repair time in summer has consumed on the change rail is insulating for a large part of time. 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.
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. 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.
Disclosure of Invention
In view of the above, the present invention provides a method for reconstructing a rail section insulation, which solves the problems of deformation and aging of rail insulation caused by temperature change in a climate environment, improves the service performance of the rail section insulation and the service cycle of the rail section insulation, and greatly reduces the cost for maintaining a track circuit.
In order to achieve the purpose, the invention adopts the following technical scheme: a method for reconstructing a section of a steel rail in an insulating way comprises the following steps: s1, recycling the damaged plastic ceramic section insulation, and taking out the ceramic beads in the plastic ceramic section insulation;
s2, recovering the nylon section insulation with complete surface, and punching the nylon section insulation according to different bearing points of the plastic ceramic section insulation on the bearing force of the steel rail;
s3, filling the ceramic beads recycled in the step 1 in holes with insulating nylon sections, and fixing the ceramic beads and the whole body to obtain the modified insulating nylon ceramic beads sections.
Further, in step 3, the ceramic beads and the whole body are fixed by hot melt adhesive.
Furthermore, 3 holes are drilled in the upper insulating part of the nylon section in the step 2, the diameter of each hole is 6mm, and the interval between the two holes is 20 mm; 4 holes are drilled in the lower insulating part of the nylon section, the diameter of each hole is 6mm, and the interval between the two holes is 25 mm.
The invention has the beneficial effects that:
the method for reconstructing the section insulation of the steel rail combines the advantages of two materials of plastic ceramic section insulation and nylon section insulation, can solve the phenomena of brittleness and aging of plastic ceramic caused by temperature environment change, can also enhance and resist impact force and compression force generated by locomotives and vehicles through the nylon material, and obviously prolongs the service life and service life of the section insulation of the steel rail.
According to the method for reconstructing the section insulation of the steel rail, through reconstructing the section insulation of the steel rail, a red light band caused by the damage of the rail insulation is reduced, the fault rate of a rail circuit is greatly reduced, and the service performance of the section insulation of the steel rail and the service cycle of the section insulation of the steel rail are improved; the maintenance efficiency of the maintainers is improved, the labor intensity of the maintainers is reduced, and the labor cost is saved.
The method for reconstructing the section insulation of the steel rail fully utilizes the damaged steel rail insulation sheet, and completes reconstruction on the utilization of waste materials on the basis of not increasing the maintenance cost. The maintenance cost is reduced, the regional environment is protected, the cost for maintaining the track circuit is greatly reduced, and three purposes are achieved at one stroke.
