Abstract

The utility model discloses a kind of low capacity rail buffer, combined by multiple buffer cells, the buffer cell includes steel plate and rubber strip, and two rubber strips are respectively arranged on two side planes of the steel plate, and the outer surface of the rubber strip is provided with blind hole or projection.The utility model is combined by by steel plate with rubber strip, buffering, the damping needs of small marshaling can be met, its maximum impact force is up to 1250KN, capacity 47KJ, absorptivity 80%, this buffer has the advantages that damping is good, low cost of manufacture, can be widely used for less than 50 small marshalings；Blind hole can be more convenient, assemble each buffer cell exactly with the cooperation of projection；The setting of groove enables buffer preferably to discharge impulsive force.

Description

Low capacity rail buffer

Technical field

The utility model is related to a kind of buffer, more particularly to a kind of for playing cushioning effect between different railway equipments Low capacity rail buffer.

Background technology

Railroad train completes shipping and passenger service by locomotive traction vehicle, and car is passed through between locomotive and some vehicles Shackles connects, and the impact between velocity variations and vehicle in train operation will cause serious injury to vehicle and load, excellent Vehicle bumper can protect vehicle and its goods from the influence of cushion effect, tractive force and deceleration forces.Hook delays system Industry is continually striving to research and develop new product, manufacture buffer with new material and new design, and expect acquisition more preferably into Really.

At present, Large Copacity buffer has good buffering effect, but its structure is complex, and is not suitable for smaller device Damping of shocks between part.Existing low capacity buffer, typically no special design, staff is according to practical application needs Interim to realize pooling feature using materials such as rubber, its power that withstands shocks is small, effect is not ideal enough and is not easy to install application.

Utility model content

The purpose of this utility model is that and provide that a kind of impulsive force is carried larger and is easy in order to solve the above problems The low capacity rail buffer of application is installed.

The utility model is achieved through the following technical solutions above-mentioned purpose：

A kind of low capacity rail buffer, is combined by multiple buffer cells, and the buffer cell includes steel plate and rubber Adhesive tape, two rubber strips are respectively arranged on two side planes of the steel plate, and the outer surface of the rubber strip is provided with blind hole Or projection.Rubber have elasticity and in elastic deformation can energy absorption, be a kind of preferable padded coaming, but due to bearing Impulsive force is small to cannot be directly used to railway car draft gear, and the utility model to be combined rubber with steel plate can just overcome this and ask Topic；Using when, the assembling for realizing whole buffer is mutually fitted together to by blind hole and projection between multiple buffer cells, by buffer It is placed in i.e. achievable pooling feature between two equipment.

Compensator or trimmer pressure is discharged for the ease of rubber strip, the outer surface of the rubber strip is provided with one or more groove.Should The space that groove is formed can provide more expansion spaces when rubber strip is extruded, and buffer is had more preferable " bullet Property ".

According to application needs, the outer surface of a rubber strip is provided with the blind hole, another rubber strip Outer surface is provided with the projection supporting with the blind hole；Or, the outer surface of two rubber strips is equipped with described Blind hole；Or, the outer surface of two rubber strips is equipped with the projection.

Specifically, on every outer surface of the rubber strip the blind hole or the quantity of the projection is 2-4.

Preferably, the rubber strip vulcanization by way of located at the steel plate two side planes on, so make steel plate with Combination between rubber strip is even closer.

The beneficial effects of the utility model are：

The utility model is combined by by steel plate with rubber strip, can meet buffering, the damping need of small marshaling Will, its maximum impact force has damping good, low cost of manufacture up to 1250KN, capacity 47KJ, absorptivity 80%, this buffer Advantage, can be widely used for less than 50 small marshalings；Blind hole can be more convenient, assemble each buffering exactly with the cooperation of projection Unit；The setting of groove enables buffer preferably to discharge impulsive force.

Brief description of the drawings

Fig. 1 is the side structure schematic view of the buffer cell of low capacity rail buffer described in the utility model；

Fig. 2 is the main structure diagram of the buffer cell of low capacity rail buffer described in the utility model；

Structural representation when Fig. 3 is low capacity rail buffer application described in the utility model, visual angle is consistent with Fig. 1.

Specific embodiment

The utility model is described in further detail below in conjunction with the accompanying drawings：

As shown in Figure 1, Figure 2 and Figure 3, low capacity rail buffer described in the utility model combined by multiple buffer cells and Into the buffer cell includes steel plate 1 and rubber strip 2, and two slat gum bars 2 are respectively located at the two of steel plate 1 by way of vulcanization On side plane, the outer surface of rubber strip is provided with two grooves 5, can also be as needed one or more bars, the shape of groove 5 Shape is circular arc or pointed shape, and the outer surface of rubber strip 2 is provided with blind hole 4 or projection 3, the outside of rubber strip 2 in this example Surface is provided with a blind hole 4 and a projection 3 supporting with blind hole 4, can also design as follows as needed：One slat gum bar 2 Outer surface is provided with blind hole 4, and the outer surface of another slat gum bar 2 is provided with the projection 3 supporting with blind hole 4；Or, two slat gums The outer surface of bar 2 is equipped with blind hole 4；Or, the outer surface of two slat gum bars 2 is equipped with projection 3；Blind hole 4 and projection 3 Quantity can also as needed depending on.

As shown in figure 3, using when, realize whole buffering by the way that blind hole 4 and projection 3 are mutually chimeric between multiple buffer cells The assembling of device, buffer is placed between the first equipment 8 and the second equipment 9, by screw rod 6 and nut 7 by the first equipment 8 and Two equipment 9 are coupled together.When the first equipment 8 or the second equipment 9 are pressurized, rubber strip 2 is extruded thinning and simultaneously to recessed Groove 5 and edge swell, realize bumper and absorbing shock function, and steel plate 1 ensures that buffer will not be damaged；After distress resolves, rubber strip 2 recovers Original shape, buffer restores.

Above-described embodiment is preferred embodiment of the present utility model, is not the limit to technical solutions of the utility model System, as long as the technical scheme that can be realized on the basis of above-described embodiment without creative work, is regarded as falling into In the rights protection scope of the utility model patent.
