Abstract
The utility model is improved of the present rail end insulation which is composed of a rail type insulating part (thick 7-10 mm) and a steel fragment (thick 1 mm). The punched hole molding press is embedded in the both sides of the rail type insulating part. So the utility model can effectively enhance the compression resistant, tensile and abrasion resistance, prolong the component service life. The utility model has the advantages of long service life, simple fabrication, convenient operation and low cost.
Description
The utility model relate to a kind of between railway signal control system middle orbit circuit rail the track-end insulation device of electrical insulation in addition.
For many years, the employed material of domestic railway track-end insulation is vulcanized fiber board, nylon 6 or MC nylon, because performances such as the resistance to compression of material, tension, wear-resisting, high-low temperature resistant and humidity, can not stand the frequent impact that rail track is taken in and is produced when wheel walks to rail gap for a long time, the variable effect of extruding and natural temperature, cause existing track-end insulation to be damaged and fracture, cause failure of insulation, influence the normal operation of railway.In addition, because maintenance load is big, jeopardize driving and personal safety.
The purpose of this utility model is the reinforced track-end insulation that proposes a kind of resistance to compression, tension, wear-resisting, long service life, to guarantee the operate as normal of whistle control system, reduces maintenance load simultaneously.
The utility model can reach by following measure: the reinforced track-end insulation that is made of rail type insulating part and stalloy, the thickness of insulating part is 7～10 millimeters, overall size is little 1～5 millimeter than the standard rail section size, material useable glass steel, vulcanized fiber board, nylon 6, nylon 1010, modified resin, phenolic aldehyde glass fabric, propylene and polyethylene and ethylene copolymers, MC nylon.Thick 1 millimeter of steel disc; Width is narrow 1～3 millimeter than rail web of the rail size; Length is lacked 10～15 millimeters than the height of rail type insulating part, is close to the one side of rail type insulating part and rolls Da Hua, and the punching mold pressing embeds insulating part two surfaces.
The utlity model has following advantage: tension, resistance to compression, wear-resisting, the rigidity of raising insulating part, manufacture simply more than 5 times the application life that can prolong track-end insulation, and easy to use, cost is low.
Fig. 1 is the elevation of reinforced track-end insulation structure, and Fig. 2 is its sectional view
Now in conjunction with the accompanying drawings the utility model is described further: thick 7～10 millimeters of rail type insulating part (1), overall size is little 1～5 millimeter than the standard rail section size, material useable glass steel, vulcanized fiber board, nylon 6, nylon 1010, modified resin, phenolic aldehyde glass fabric, propylene and polyethylene and ethylene copolymers, MC nylon, fortifying fibre glass fiber reinforced plastic.Thick 1 millimeter of steel disc (2), width is narrow 1～3 millimeter than standard rail web of the rail size, length is lacked 10～15 millimeters than the height of rail type insulating part (1), be close to the one side of insulating part (1) and roll Da Hua, punching (3) interlaced arrangement, can be washed into multiple shapes such as rib type, dovetail, example 8, ellipse and band in conjunction with the hole of tooth, two steel disc mold pressings are embedded two surfaces of insulating parts (1) or a steel disc mold pressing is placed the mid-depth position of insulating part (1), constitute reinforced track-end insulation.
Claims (3)
1, a kind of track-end insulation spare that is used for railway signal track circuit, the two sides of rail type insulating part (1) that is characterised in that of the present utility model is embedded with stalloy (2), constitutes reinforced track-end insulation.
2, reinforced track-end insulation according to claim 1, it is characterized in that thick 7～10 millimeters of rail type insulating part (1), overall size is little 1～5 millimeter than the standard rail section size, material can be used nylon 1010, modified resin, phenolic aldehyde glass fabric, propylene and polyethylene and ethylene copolymers, MC nylon, fortifying fibre glass fiber reinforced plastic.
