Abstract
The utility model discloses a kind of track switch lead curve of eliminating and surpasses in reverse high device, comprise pad, it is characterized in that: described pad is comprised of pad one and pad two, pad one is provided with fin for cuboid plate and a side, cuboid main body is provided with two grooves, and pad two is for cuboid plate and both sides are equipped with fin, and pad one is arranged between backing plate and sleeper, pad two is arranged on backing plate top, between backing plate and rail.By using the pad of the utility model design to combine, can effectively eliminate the high hidden danger that surpasses in reverse within the scope of 4～12mm, effectively solve the little a large amount that surpasses in reverse and process difficult problem.
Description
Technical field
The utility model relates to a kind of track switch lead curve of eliminating and surpasses in reverse high device.
Background technology
The positive linear distance of the inner railway of smelter is short, and road branch group number is many, and take wooden switch tie as main, and its structure is by steering unit, railway frog and guard rail, coupling part, and wherein coupling part is comprised of lead curve and stock rail.Under planting flag of vehicle rolled, recessed in the middle of long concrete pillow, and be difficult for recovering.Cause lead curve silent partners to occur lower than the phenomenon of interior thigh, be called lead curve and surpass in reverse height, for line security driving hides some dangers for.When the amount of surpassing in reverse is 5～8mm, maintenance troop is subject to the restriction of technical condition, instrument, and extremely difficulty is corrected elimination, even if it is extremely short again to eliminate hold period, causes this hidden danger to be difficult to effective elimination.
Railway is laid in rules and is stipulated, two strands of faces of track switch lead curve must be in same level, and curved section foreign stock rail should be higher than interior strand.In sum, the lead curve causing due to sleeper defect surpasses in reverse high has hidden huge potential safety hazard to safe driving.
According to service experience, curve occurs surpassing in reverse when high, if the main track in non-switch area is comprised of two station tracks, can raise track by press, tamping operation, raises foreign stock rail and eliminates and surpass in reverse high hidden danger.But for the height that surpasses in reverse of the lead curve of switch area, if eliminate by track lifting, will raise the height of straight stock rail, the hidden danger that has simultaneously caused the straight burst level of track switch to transfinite.In addition, according to the experience of long-term maintenance, when track switch lead curve surpasses in reverse a large amount and is 5～8mm, maintenance troop is extremely difficult controls track lifting operation, is difficult to keep the line status of regulation after track lifting, and causing lead curve to surpass in reverse the hidden danger that a large amount is less can not eliminate at all.For the height that surpasses in reverse more than 20mm, generally with the method for raising track, can be eliminated.And for the high hidden danger that surpasses in reverse of track switch lead curve 5～8mm, maintenance troop does not have effective elimination way.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of track switch lead curve of eliminating to surpass in reverse high device, by designing, be a kind ofly simply easy to do, and be easy to install, and the pad that can fixedly secure, insert under backing plate or between rail and backing plate, to raise the height of bearing plate bars or rail, and realize eliminating, surpass in reverse high object.
The technical solution adopted in the utility model is: a kind of track switch lead curve of eliminating surpasses in reverse high device, comprise pad, it is characterized in that: described pad is comprised of pad one and pad two, pad one is provided with fin for cuboid plate and a side, cuboid main body is provided with two grooves, and pad two is for cuboid plate and both sides are equipped with fin, and pad one is arranged between backing plate and sleeper, pad two is arranged on backing plate top, between backing plate and rail.
The thickness of described pad one is 2 ~ 6mm, and two grooves on pad one are corresponding with the bolt hole on backing plate, by bolt, come fastening backing plate and sleeper.The fin of pad one is clamped on the side of backing plate.
The thickness of described pad two is 2 ~ 3mm, and the length of pad two inner sides equates with the width of backing plate, and pad two tips upside down on backing plate, and the fin of pad two both sides is stuck in the two ends of backing plate two.
Pad of the present utility model can be designed to different thickness, for the different a large amounts that surpasses in reverse, take that to adopt the least possible pad quantity be principle, compound gasket kind, during installation, unclamp bolt, a little raises rail, and pad is inserted from the side, insert under backing plate or between rail and backing plate, to reach, eliminate the object that surpasses in reverse high hidden danger.
The elimination track switch lead curve that the utility model provides surpasses in reverse high device, by using the pad of the utility model design to combine, can effectively eliminate the high hidden danger that surpasses in reverse within the scope of 4～12mm, efficiently solve the little a large amount that surpasses in reverse and process difficult problem, the utlity model has following advantage:
(1) in elimination track switch lead curve, be difficult to the high hidden danger that surpasses in reverse by normal track lifting operation elimination.
(2) simplify and eliminate the processing method that surpasses in reverse high hidden danger;
(3) reduce the input of manpower and materials;
(4) that can emergent management finds surpasses in reverse high hidden danger.
Below in conjunction with drawings and Examples, the utility model is described further.

The specific embodiment
Embodiment:
As shown in Figure 1, 2, 3, a kind of track switch lead curve of eliminating surpasses in reverse high device, comprise pad, it is characterized in that: described pad is comprised of pad 1 and pad 24, pad 1 is for cuboid plate and a side are provided with fin, and cuboid main body is provided with two grooves 7, pad 24 is equipped with fin for cuboid plate and both sides, pad 1 is arranged between backing plate 2 and sleeper 1, and pad 24 is arranged on backing plate 2 tops, between backing plate 2 and rail.
The thickness of described pad one is 2 ~ 6mm, and two grooves on pad one are corresponding with the bolt hole on backing plate, by bolt, come fastening backing plate and sleeper.The fin 5 of pad one is clamped on the side of backing plate 2.
The thickness of described pad two is 2 ~ 3mm, and the length of pad two inner sides equates with the width of backing plate, and pad two tips upside down on backing plate, and the fin 6 of pad two is stuck in the two ends of backing plate 2.
Design as required the pad of different-thickness, for the different a large amounts that surpasses in reverse, take that to adopt the least possible pad quantity be principle, compound gasket kind, unclamps bolt during installation, a little raises rail, pad is inserted from the side, to reach, eliminate the object that surpasses in reverse high hidden danger.
