Technical field
The utility model relates to railway casting manufacturing technology field, is specifically related to a kind of rail that is used to be placed between rail and the concrete pillow and adjusts pad down.
Background technology
Because eliminating of the heavy-duty of track and sleeper, a large amount of uses of concrete pillow make the railway maintenance operating type that the change of essence take place.Adopt the operating type of in the past traditional manual raise track tamping can not adapt to the development of railway, the Ministry of Railways repeatedly proposes " making firm by ramming with tamping pickaxe is exactly destruction ", to the railway overhaul, in repair should be with the large, medium and small type mechanized of a large amount of uses.
At present, often the bamboo pad that adopts usually needs timely replacing after wearing out owing to rupturing, thereby operation labor intensity causes the increase of maintenance cost in a large number.Because the pad of rail expands, shrinkage, creep, the bamboo gasket surface is very sliding to skid off under track easily, and the personnel that inspect the road are not easy again to find, can cause a series of problems such as " boatswain chairs ".Practice shows, rubber sheet gasket cost height, and resistance to compression distortion is big, and aging easily, application life is short, and thin then being easy to of pad damaged, and thickening then distortion is big, and problem such as inconvenient spacer thickness inspection.
In sum, traditional rail is conspicuous with the shortcoming of pad.For this reason, this patent proposes to adjust under a kind of rail pad with regard to problems of the prior art.
The utility model content
In order to overcome above-mentioned deficiency of the prior art, the utility model provides and adjusts pad under a kind of rail, this rail is adjusted down advantages such as pad has simple in structure, light and flexible, use is easy to maintenance, security performance is good, " level ", " the seeing the hole ", " twist irregularity ", " dark boatswain chair " and the uneasy congruent problem of track lifting operation that exist in the maintenance activity have not only been solved, and reduce labour intensity and maintenance cost significantly, can solve the problem that can't carry out maintenance activity because the work area personnel are few preferably.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: provide and adjust pad under a kind of rail, be used for pad and be located between concrete pillow and the rail, it is characterized in that: it is rectangular platy structure that described rail is adjusted pad down; Adjustment pad pad is located under the rail and is pressed on above the rubber pad and with rail under the described rail, and rubber pad is close to concrete pillow upper surface under the rail; Described rail is adjusted pad down and is adopted the hp-ldpe material; The width that described rail is adjusted rubber pad rail under pad and the rail down is consistent.
Adjust pad down according to rail provided by the utility model, it is characterized in that: described rail is adjusted place, pad both sides of the edge down and respectively is provided with a spacing shoulder block; The width of rubber pad is consistent under width between two described spacing shoulder blocks and the rail; Rubber pad is connected between two spacing shoulder blocks under the rail under the described rail below the adjustment pad.
Adjust pad down according to rail provided by the utility model, it is characterized in that: adjustment pad upper surface is established and is arranged with rhone in parallel under the described rail.Described rhone is provided with 3 at least.
Adjust pad down according to rail provided by the utility model, it is characterized in that: the cross section of described rhone is V font or U font or semicircular structure.
Adjust pad down according to rail provided by the utility model, it is characterized in that: the thickness that described rail is adjusted pad down is 1-8mm, and width is 130-200mm, and length is 130-1000mm.
In sum, rail provided by the utility model is adjusted down advantages such as pad has simple in structure, light and flexible, use is easy to maintenance, security performance is good, " level ", " the seeing the hole ", " twist irregularity ", " dark boatswain chair " and the uneasy congruent problem of track lifting operation that exist in the maintenance activity have not only been solved, and reduce labour intensity, maintenance cost significantly, can solve the problem that can't carry out maintenance activity because the work area personnel are few preferably.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in detail.
Fig. 1 adjusts the user mode schematic diagram of pad down for this rail; Fig. 2 is a structural representation of adjusting pad under the flat rail.As shown in the figure, this rail is adjusted down pad and is used for pad and is located between concrete pillow 3 and the rail 1, and it is characterized in that: described rail is adjusted pad 2 down and is rectangular platy structure; Adjustment pad 2 pads are located under the rail and are pressed on above the rubber pad and with rail 1 under the described rail, and rubber pad is close to concrete and rests the head on 3 upper surfaces under the rail; Described rail is adjusted pad 2 down and is adopted the hp-ldpe material; The width that described rail is adjusted rubber pad rail under pad 2 and the rail down is consistent.Adjustment pad 2 upper surfaces are established and are arranged with 3 rhones 4 in parallel under the described rail.The thickness that above-mentioned rail is adjusted pad 2 down is 1-3mm, and width is 130-200mm, and length is 130-1000mm.
Fig. 3 is the following structural representation of adjusting pad of rail that is provided with spacing shoulder block.As shown in the figure, this rail is adjusted place, pad 2 both sides of the edge down and respectively is provided with a spacing shoulder block 5; The width of rubber pad is consistent under width between two described spacing shoulder blocks 5 and the rail; Rubber pad is connected between two spacing shoulder blocks 5 under the rail of the following adjustment of described rail pad 2 belows.The thickness that above-mentioned rail is adjusted pad 2 down is 4-8mm, and width is 130-200mm, and length is 130-1000mm.
In conjunction with engineering practice, above-mentioned rail is adjusted pad down can determine color according to following table:
