Description

A kind of steel rail end high-strength composite material insulating part
Technical field
The utility model relates to a kind of insulating part, specifically is a kind of electric insulation that is applied between the rail rail, be installed between the slit at rail joint place, and be the high-strength insulation spare of making by composite material.
Background technology
As everyone knows, when placing an iron railway steel rail line, rail joint will inevitably occur, on the railway line of implementing to automatically close up in driving, be equiped with track circuit, insulating part all is housed in the place of track two ends rail joint.Because prior art can't solve scuff resistance, environmental protection and invar rail wearing and tearing and adjust the problem of the height of steel rail end insulating part self automatically, a kind of rail rail end glass fiber reinforced plastic compound inslation pad is disclosed as patent No. CN88200067, the external surface of this I shape insulating trip all is smooth, can't solve invar rail wearing and tearing and adjust the problem of the height of steel rail end insulating part self automatically, its scuff resistance is not high, thereby cause replacement of products frequent, cause raw-material waste, original product has used a part of 3240 epoxy phenolic laminated glass fabric plates (specification is 2000mm*1000mm substantially) in addition, carrying out secondary operations (being sawn into standard shape) can use, pollute in secondary processing process, for the environment and the person, and this material can't dissolve, and does not have the value of second use.Existing insulating part is in case damage, as untimely replacing, will produce rail return is communicated with, make signal of communication inaccurate and jeopardize traffic safety, therefore track-end insulation spare not only requires to have high mechanical strength and electrical insulating property, but also requirement has the higher feature of environmental protection, abrasion resistance and the automatic performance of adjusting steel rail end insulating part oneself height.
Therefore, need design a novel insulating part, to solve the feature of environmental protection, the not good problem of abrasion resistance.
Summary of the invention
The purpose of this utility model just provides a kind of steel rail end high-strength composite material insulating part, effectively solves the wearing and tearing of scuff resistance, environmental protection and invar rail and can not adjust the problem of the height of steel rail end insulating part self automatically.
For achieving the above object, the basic design of technical scheme provided by the utility model is as follows:
The utility model provides a kind of steel rail end high-strength composite material insulating part, comprise upper beam, middle part, underbeam, its special character is, described insulating part is injection molded into one by two I-shaped insulation modules 11, top, the right and left of putting the beams in place is respectively equipped with horizontal adjustment line 21, vertically adjusts line 22, adjusts between the line and leaves space 23.
Described insulating part is injection molded into one by the filler particles of installing in two I-shaped insulation module 11 concave points 12 inner with it 13.
Described horizontal adjustment line 21 is 2～4 roads, highly is 1～10mm, and vertical adjustment line 22 every limits on upper beam both sides are 1～2 road, and width is 1～15mm.
Described filler particles 13 diameters are 5～8mm, and regular distribution is at insulating part upper beam, middle part, underbeam.
Being distributed as of described filler particles 13: 1～3 row and 4～10 row are arranged in the upper beam, 4～8 row and 1～2 row are arranged in the middle part, have 1～2 group in the underbeam, every group has 4～20, every composition splay configuration or rhombus.
Described insulating part is made of in nylon 6, nylon 1010, rubber, thermoplastic macromolecule material, the thermoset macromolecule material any one.
Described filler particles 13 can be two or more formation in charcoal fiber grain, high silica particle, zirconia particles, zirconium silicate particles, the alumina particle.
Compared with prior art, the utlity model has following advantage:
1, the utility model insulating part is injection molded into one by two I-shaped insulation modules, and insulating part is by in nylon 6, nylon 1010, rubber, thermoplastic macromolecule material, the thermoset macromolecule material any one; Need not secondary operations, save operation, feature of environmental protection height has the value of second use.
2, the utility model when mounted, comes the shape of random cutting insulating part with corresponding rail cross section according to the size of rail owing to adopted many vertically, laterally to adjust line; In use, can regulate the height and the width of steel rail end insulating part, reach the effect of buffering, prevent that the insulation of wheel bump steel rail end from causing slight crack and hard defects, increases the life-span that insulating part uses according to the rail abrasion degree.
3, the utility model insulation inside modules is provided with concave point, installs filler particles in concave point, and filler particles can be two or more in charcoal fiber grain, high silica particle, zirconia particles, zirconium silicate particles, the alumina particle; When wheel passes through, clash into insulating part between the rail end mutually, and be difficult for making insulating part to cause fracture, strengthened the abrasion resistance of insulating part greatly,, can save 8-10 maintenance cost doubly than increasing 10-15 in application life of existing product doubly, artifical influence factor reduces, traffic safety is greatly improved, and cost performance is outstanding, and the insulating part under changing can 100% recovery.
The utility model is simple in structure, easy for installation, cheap, electrical insulating property is good, abrasion resistance is strong, long service life, be beneficial to environmental protection, have second use to be worth, can to adjust automatically the performance of insulating part oneself height in the driving wear process; Utility model can be widely used on groove typed insulation, track-end insulation, insulation pipe pad, the track switch seal.
