Abstract
The present invention relates to dress locating pin (hook nail) 2 iron sleeper 1 in a kind of having, directly cast and form, be applicable to the locking rail by cast iron.
Guarantee locking and the plate that need not move built in the cast iron locating pin (hook nail) 2 of iron sleeper 1 inside, simultaneously, guaranteed the gauge that can obtain expecting in the casting stage.The performance that used material assurance has long-term withstand voltage proof stress and do not wear and tear.
Description
The present invention relates to a kind of cast iron sleeper that has interior dress locating pin (hook nail), is used for rail.
Known from institute, the iron sleeper of most of employing is that variety classes, warp are suitably handled and processing wood is made at present, and the rail connector is set on wooden sleeper.
The average life span of sleeper is 15~20 years.Because wooden valency rises steadily, buying difficulty (most of wood is import), people need replace this part of rail.
In addition, also have a kind of in the dress timber wedge, by the iron sleeper that pre-compressed reinforced concrete is made, by tightening pin fixed head is fixed, on fixed head, lock rail then.
Described pre-compressed reinforced concrete pillow has replaced the function of wooden stress distribution device, but must arrange locating pin in addition, before preparation, carries out drying, dipping and bitumen treatment work, and obviously, everything cost is very big.
The sleeper (even it is the most out in the cold) that also useful steel is done, it is made with the assembling locking member by forge hot and boring.This steel sleeper expense height, filler is difficult for, and is not used widely, because this steel sleeper is discharged to stress on the short rib of pillow, and can not be close on the roadbed fully.
The present invention can obtain iron sleeper 1 by casting, and the latter has good and mechanical performance that determine, can satisfy the compressive resistance stress of essential intensity and rail in the best way, makes stress distribution to a big surface.Locating pin 2(and iron sleeper 1 that employing is made through casting are cast together, form one), allow system's locking rail of forming with common block and plate.
With regard to the characteristic properties that material had, cast iron iron sleeper 1 of the present invention in fact the life-span very long, do not need import; Because its structure and shape, its stress distribution is optimization; The intensity that it provides a suitable heavy load and transport fast for rail; It does not need make separate arrangements locating pin and fixed head, because they are made when casting together.
In addition, compare with the sleeper of traditional type, it also has some great advantages.The gauge that when casting, can obtain being scheduled to, locating pin (hook nail) is because cast, can not move (different with all at present used sleepers, present sleeper is because vibrations and fret wear, bolt, pin etc. all may be moved), therefore gauge immobilizes, and in fact there is no need maintenance, has maximum safety.
As an example, we will narrate an embodiment, and the casting shape of described cast iron sleeper is to form in the stop block of the mixture of sand and resin with model.After model takes out, insert the core of described foundry goods reinforcing rib.
Core changes according to the geometry of locating pin (hook nail), can satisfy required variation.
Model is coated with to be coated, and after the moulding mixture cures, can enter the casting stage.
The liquid cast that meets the foundry goods mechanical performance after is by analysis poured into model, after hardening process finishes, carry out vibrating shakeout and remove burr.
If necessary, carry out one-time mechanical processing, make locating pin (hook nail) have required that be complementary with fastening hook, accurate geometry.
So just obtained dress locating pin cast iron sleeper 1 (hook nail), that be used for rail in a kind of having.
In addition, described pillow 1 can have various cross sections (referring to cast iron locating pin (hook nail) when being contained in inside).
Also have, described pillow 1 can be hollow fully, has different thickness, fills up (for example sand) with inert material, so that vibration damping, obviously like this can obtain a lighter foundry goods.The present invention can understand better with following accompanying drawing, and shown figure is an embodiment according to the invention.
Fig. 1 is the front view of pillow 1; Fig. 2 is the view in transverse section of pillow 1; Fig. 3 is the vertical view of pillow 1.
Thickness shown in the figure, shape, length, cross section are one of best solutions for function, optimum shape and gross weight.
Therefore we point out, described in the invention and just one embodiment of the present of invention shown in the figure, because its details such as shape, size, manufacturing and material can change, therefore, although change, they still belong to range of the present invention.
Claims (9)
1, have in the rail cast iron sleeper of dress locating pin (hook nail), it is characterized in that this iron sleeper made by iron sleeper 1 and locating pin 2; Form because they are casting, therefore form a single integral body.
2, the sleeper that requires according to aforesaid right is characterized in that described sleeper has long-term good and definite mechanical performance, meets the requirement of essential intensity and compression resistance stress.
3, the sleeper that requires according to aforesaid right is characterized in that having one and it seems it is the life-span of endless.
4, the sleeper that requires according to aforesaid right is characterized in that because its structure is very even, so the stress distribution optimization.
5, the sleeper that requires according to aforesaid right is characterized in that the intensity that it provides a suitable heavy load and transport fast for rail.
6, the sleeper that requires according to aforesaid right is characterized in that its location nail-plate 2 of need not making separate arrangements, and they form by casting.
7, the sleeper that requires according to aforesaid right is characterized in that the gauge that can obtain expecting in cast sections.
8, the sleeper that requires according to aforesaid right is characterized in that locating pin 2 owing to can not move by casting formation event, so gauge is changeless.
9, the iron sleeper that requires according to aforesaid right, it is characterized in that this iron sleeper fully with described consistent with shown in the accompanying drawing.
