Abstract
A kind of railway is used to prevent the anti-skidding skate of locomotive, wagon running away, by way of increasing dismountable elastic anti-slip pad in traditional skate afterbody, a kind of anti-skidding skate for preventing that skate from sliding on rail is provided, overcome traditional skate because between rail frictional force it is too small, when wheel rolling touches skate tip, skate easily slides backward and lost the shortcoming of anti-slip effect under wheel squeezing action, ensure that skate will not be slided when wheel touches skate, reach that reliability prevents the purpose of locomotive, wagon running away.
Description
Technical field
The utility model belongs to a kind of locomotive for preventing from parking of railway, the skate of wagon running away, specifically one
Plant the anti-skidding skate with antiskid function.
Background technology
In railway transportation production process, locomotive and vehicle are frequently necessary to park in specified place, due to by track slope
Runaway may occur for the influence of the factors such as degree, wind-force, the locomotive parked, vehicle, directly result in railway security accident.In order to anti-
The method generally used on only locomotive, wagon running away, current railway is that skate is placed on rail, and locomotive, car are prevented with skate
Wheel is rolled, so that reaching prevents the purpose of locomotive, wagon running away.Skate is by groups such as toe cap, sole, riser, tread, footwear tails
Into its toe cap has 2+1mm thickness, therefore, and skate is positioned over equivalent to one step of toe cap on rail, when the wheel of rolling connects
When contacting toe cap, skate shoes tip can by the active force from wheel, this power can be analyzed to pressure vertically downward and
To the horizontal thrust in skate direction, when the horizontal thrust that skate is subject to is more than the frictional force between skate and rail, skate is just
It can be slided backward on rail, so that losing prevents the effect of locomotive, wagon running away.Technically, skate loses anti-slip
The main cause of effect is because the frictional force between skate and rail is small and causes.Publication No. CN2194846y, it is open
Date " light brake shoe that rolling stock is used " disclosed in 1995.04.19 utility model patent wraps up wood by fiberglass
Rod is constituted, and the characteristics of it is most prominent is the coefficient of friction between very light in weight, and fiberglass and steel and little, is not had in wheel
In pressure during anti-slip footwear, because frictional force is multiplied by normal pressure equal to coefficient of friction, it is light anti-described in the utility model patent
The frictional force very little between footwear and rail is slipped, it is easier to slide when wheel rigid connection contacts the anti-slip footwear, so as to lose anti-
The effect of slipping.
The content of the invention
Slided to overcome the shortcomings of traditional skate to readily occur on rail, the utility model provides a kind of Antislip iron
Footwear, can guarantee that skate will not be slided backward under wheel squeezing action when wheel touches skate, if wheel is touched after skate
Continue to roll, skate will be pressed, so as to reach that reliability prevents the purpose of locomotive, wagon running away.
The technical scheme in the invention for solving the technical problem is：Traditional skate afterbody increase by one with
The larger slipmat of coefficient of friction between rail, under uniform pressure effect, because the increase of coefficient of friction, anti-skidding skate and steel
Frictional force between rail is far longer than the frictional force between traditional skate and rail, can be prevented effectively from the iron under wheel squeezing action
Footwear are slided backward on rail, so as to reach reliable anti-slip purpose.Slipmat selects the coefficient of friction between rail larger
Elastomeric material (such as thermoplastic rubber), it is detachable form with the connected mode of skate；From the side, slipmat is to be clipped in skate
Wedge shape between afterbody and rail；Its thickness (can be suitable according to the elasticity of elastomeric material to exceed skate bottom surface 5mm or so after installing
Degree adjustment)；The angle of wedge shape is placed on rail slipmat bottom surface and rail surface is closely connected is defined to be installed on after skate afterbody；It is anti-skidding
The connection method of pad and skate is bolt connection.
The beneficial effects of the utility model are, anti-slip reliable effect.Due to adding slipmat, the utility model can guarantee that
Skate will not be slided backward under wheel squeezing action when wheel touches skate, reached that reliability prevents locomotive, wagon running away, kept away
Exempt from the purpose of railway security accident generation.The utility model embodiment is simple and easy to apply, and slipmat is detachable, is easy to maintenance more
Change.With Publication No. CN2194846y, publication date is compared for 1995.04.19 utility model patent, the autotelic choosing of this case
Make slipmat of the big material as far as possible of coefficient of friction between steel, and to greatest extent using existing skate and rail it
Between normal pressure, light brake shoe described in documents all phase compared with this case in terms of coefficient of friction, particularly normal pressure
It is far short of what is expected, so skate its frictional force between rail can effectively be increased by handling a case, realize reliable anti-slip.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the front view of the utility model embodiment.
Fig. 2 is the top view of the utility model embodiment.
In figure, 1 skate, 2 connecting bolts, 3 slipmat liner plates, 4 slipmat
Embodiment
In figure, the afterbody of skate 1 upwarps one circular hole of processing in the middle of place；Slipmat liner plate 3 is and skate afterbody upturned portion
Shape is identical, be highly less than skate afterbody upwarps the sheet metal that height, center locally thicken simultaneously machining internal thread；Elastic anti-slip pad
4 it is integrated poured with slipmat liner plate 3 together with form an entirety, and be connected by connecting bolt with skate afterbody.In wheel
When not pressing skate, skate toe cap end and slipmat and rail surface contact on rail, when wheel rolling touches skate
When sharp, between slipmat and rail in the presence of larger frictional force, skate will not be slided backward, and wheel continues to roll
Dynamic to press skate, locomotive, wagon running away are prevented from.On pressure wheel after skate, the flexible slipmat of skate is compressed,
Whole skate bottom surface and slipmat are contacted with rail surface.
Claims (2)
1. a kind of anti-skidding skate, is made up of toe cap, sole, riser, tread, footwear tail etc., it is characterized in that：Existing skate master is not changed
Body structure, a larger slipmat of coefficient of friction between rail is installed in the afterbody of skate below.
2. anti-skidding skate according to claim 1, it is characterized in that：The connection of slipmat and skate connects for removably
Connect.
