Abstract
The utility model discloses a glued insulation splint of seamless rail, including rail and glued insulation splint, glued insulation splint are the variable cross section, and the medial surface of glued insulation splint and the rail web laminating of rail, and glued insulation splint pass through the on-the-spot glue of high strength with the rail web of rail sticky, set up a plurality of perforation that run through and be used for erection joint bolt on the glued insulation splint, the screw hole of slope is seted up to at least one terminal surface of glued insulation splint, the screw hole runs through the terminal surface to its medial surface of glued insulation splint.
Description
Technical Field
The utility model relates to a seamless rail cementation insulation splint.
Background
At present, the cementing insulating clamp plate of the seamless steel rail is commonly adopted, and the cementing insulating clamp plate and the steel rail are fixed by adopting high-strength on-site glue, so that the cementing insulating clamp plate is closely attached to the rail web of the steel rail, the cementing insulating clamp plate and the rail web of the steel rail are glued to form a high-strength on-site glue layer, and under the action of the high-strength on-site glue layer, the integral shear strength and the fatigue resistance of a cementing insulating joint are obviously enhanced, so that the stability of the resistance characteristic of a track circuit of the steel rail is ensured; however, this also entails the very inconvenient 'side' effect of the clip removal, which makes it extremely difficult to remove the clip from the rail due to the high strength of the field adhesive. At present, the company develops the technical scheme that the prying grooves are formed in the two ends of the clamping plate, namely the inclined grooves at the two ends are utilized, the clamping plate is separated from the steel rail by the prying tool, and although the problem of difficulty in disassembly can be greatly relieved, the physical strength still needs to be greatly consumed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects in the prior art, and provide a seamless steel rail cementing insulation splint, which is convenient to disassemble the splint and the steel rail.
For realizing the above-mentioned purpose, the technical scheme of the utility model a seamless rail cementation insulation splint is provided, cementation insulation splint is the variable cross section, and the medial surface of cementation insulation splint and the rail waist laminating of rail, and the rail waist of cementation insulation splint and rail is glued sticky through the on-the-spot glue of high strength, set up a plurality of perforation that run through and be used for installing connecting bolt on the cementation insulation splint, the screw hole of slope is seted up to at least one terminal surface of cementation insulation splint, the screw hole runs through the terminal surface to its medial surface of cementation insulation splint.
The further improvement is that: the area of the threaded hole is smaller than one fourth of the area of the end face of the cementing insulation clamping plate.
The further improvement is that: the two ends of the cementing insulation clamping plate are both provided with the threaded holes.
The further improvement is that: the outer side surface of the cementing insulation clamping plate is provided with a groove, and the through hole is positioned in the groove.
The utility model has the advantages and the beneficial effects that: the prying groove is changed into an inclined threaded hole, the disassembling tool is changed into a screw rod with a handle by a prying bar, the screw rod rotates in the threaded hole by rotating, and then the clamping plate is jacked up from the steel rail by the screw rod, so that time and labor are saved, and the disassembling is convenient.
Drawings
Fig. 1 is a schematic view of the present invention.
Wherein: 1. gluing an insulating clamping plate; 2. a threaded bore.
Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1, the seamless steel rail cementing insulation clamp plate comprises a steel rail and a cementing insulation clamp plate 1, wherein the cementing insulation clamp plate 1 is of a variable cross section, the inner side surface of the cementing insulation clamp plate 1 is attached to the rail web of the steel rail, the cementing insulation clamp plate 1 is glued with the rail web of the steel rail through high-strength on-site glue, a plurality of penetrating through holes used for installing connecting bolts are formed in the cementing insulation clamp plate 1, at least one end surface of the cementing insulation clamp plate 1 is provided with an inclined threaded hole 2, and the threaded hole 2 penetrates through the end surface of the cementing insulation clamp plate 1 to the inner side surface of the cementing insulation clamp plate 1.
In order to ensure the strength of the clamping plate, the area of the threaded hole 2 is less than one fourth of the area of the end face of the cemented insulating clamping plate 1.
In order to more conveniently and efficiently detach the clamping plate from the steel rail, the threaded holes 2 are formed in the two ends of the glued insulating clamping plate 1, so that two workers can simultaneously operate from the two ends to jack the clamping plate from the steel rail, and the efficiency is high.
In the preferred embodiment of the present invention, a groove is formed on an outer side surface of the glued insulation splint 1, and the through hole is located in the groove.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
