Matching, every piece of clamping plate the diverse location of its length direction set altogether two recesses and its respectively with every piece of insulation channel plate on two
Individual convex layer matching.
In the present invention, the processing method of each part is as follows.Rail with arch dam is by the upsetting containing heating by standard rail
Thick and die mould process (being molded again to rail using special-shaped mould and forcing press) is prepared, to arch dam position during die mould
The place's of putting upset is pressed.The rail with arch dam can not be obtained by welding arch dam on standard rail in the present invention
Arrive, because the strength character of the rail with arch dam for being prepared obtaining cannot meet demand.Therefore, the band arch dam in the present invention
Rail used by steel it is identical with the steel of existing standard rail.Steel used by the clamping plate being related in the present invention equally also with it is existing
There are steel used by the standard clamping plate in technology identical, added to the material plate machine of carrying out by way of machining in the present invention
Work, obtains many two clamping plates of recess 3 compared with standard clamping plate.In the present invention, insulating end plate 8, insulating sleeve 7 and insulation
Frid 2 is the product that insulating materials shaping is obtained, and the insulating end plate 8, insulating sleeve 7 and insulation channel plate 2 use existing skill
Isolation material that is in art and meeting concerned countries standard.
Rail insulating joint in the present invention is for example applied and matched somebody with somebody on rail in switch area, wherein, the length with rail is for example
It is 3~50m, is illustrate only in Fig. 1~6 with relevant with joint section on rail length direction, without by whole steel
Rail is shown in figure completely.
In a kind of specific embodiment, the length of the clamping plate is 500~900mm, and the insulation channel plate length
Degree two ends 0~60mm more long than the clamping plate.Preferably, the length of the clamping plate is 800~900mm, and the insulation channel plate
Length in its two ends 5~30mm more long than the clamping plate.It is arranged such the effect that may be such that insulation channel plate plays abundant insulation.
In a kind of specific embodiment, the arch dam is the arch dam being integrally formed on rail.As described above, this hair
Arch dam described in bright is integrally formed during rail die mould and obtains.
Below in conjunction with accompanying drawing, the present invention will be further described.As shown in accompanying drawing 1~6, it is existing standard steel
The arch dam position limiting structure in " ︹ " shape of constant slope is processed at rail fish tail space using certain technique, other positions are not
Become, form transition rail 1.Accordingly, it is the concave slope structure in " ︺ " shape matched with rail 1, insulation tank that clamping plate 3 is processed
Plate processes " ︹ " shape structure supporting with transition rail 1 and clamping plate 3.Bolt 4, nut 5, pad 6, insulating sleeve 7 and insulation
The structures such as end plate 8 are consistent with existing structure.By existing adhesive technology by insulation channel plate 2, insulating sleeve 7, insulating end
Plate 8 is heating and curing, and forms insulation cement, tightens the bolt 4, transition rail 1 and clamping plate 3 is glued integral structure.
In the present invention, trapezoidal " arch dam " structure both sides inclined-plane forms wedge-shaped position limiting structure with the rail flange of rail, can support respectively
Tension and compression that anti-rail temperature reduction and rising are produced.The enhancing rail rubber insulating joint that the present invention is provided exists
Outside the shearing resistance that existing joint glue-line is provided, the component of the rail length direction of " arch dam " structure offer is increased again, enhance
The tension and anti-pressure ability of rail insulating joint, enhance the globality and continuity of circuit, can reduce gluded joint disease
Evil problem.Specifically, the insulating joint that the present invention is provided can make the unlikely big rail of appearance in the junction of two one steel rails of series connection
Seam, and may be such that rail insulating joint is subject to the injury of temperature stress and impact force of train and causes the possibility of failure significantly
Reduce.The present invention provide insulating joint can fully meet gapless track temperature stress change and train operation in produce
Raw impulsive force, meets the growth requirement of trans-section seamless railway.
The preferred embodiments of the present invention are the foregoing is only, is not intended to limit the invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.It is all within the spirit and principles in the present invention, made any repair
Change, equivalent, improvement etc., should be included within the scope of the present invention.
