Below by the drawings and specific embodiments, technical scheme of the present invention is described in further detail.
Embodiment one
Fig. 4 is the structural representation of axle box rubber pad embodiment of the present invention, Fig. 5 is the partial enlarged drawing of the a-quadrant among Fig. 4, in conjunction with Fig. 4 and shown in Figure 5, the axle box rubber pad of present embodiment can be used for the bogie truck of railway truck, it can comprise liner plate 16, following liner plate 17, and sulfuration is formed at the rubber layer 18 between the liner plate up and down, the thin layer rubber 19 about being formed at respectively on the liner plate outside face, hole for injecting glue 20, and be built in conductive mechanism in this hole for injecting glue 20.
Concrete, hole for injecting glue 20 can be arranged on the medium position of axle box rubber pad, this hole for injecting glue 20 can comprise the cavity that is formed in the rubber layer 18, lay respectively at first hole on the liner plate and be positioned at second hole on the liner plate down, and this first hole and second hole and cavity are communicated with.Conductive mechanism is built in the hole for injecting glue 20, and its two ends are passed by described first hole and second hole respectively, contacts with two parts that are switched on respectively, to realize conducting between these two parts.When this axle box rubber pad was used for the bogie truck of railway truck, the two ends of this conductive mechanism can contact with adapter with bogie side frame respectively.Leave the gap between conductive mechanism and the hole for injecting glue, therefore, when bogie truck moved on the line, this axle box rubber pad can adapt to compression and the shearing force that vibration of vehicle causes, the axle box rubber pad can bear vertical, horizontal and vertical displacement and can not be damaged.
At first, illustrate that the structure of conductive mechanism is as follows: in concrete enforcement, conductive mechanism can comprise first conductive pin 21, second conductive pin 22, lead 23 and spring 24.Wherein, the head of first conductive pin 21 can be passed by first hole on the last liner plate, and head end stretches out and promptly exceed the surface of going up the thin layer rubber on the liner plate, can be used for contacting with bogie side frame; The head of second conductive pin 22 can be passed by second hole on the following liner plate, and head end stretches out the thin layer rubber surface on the liner plate down, can be used for contacting with adapter.
Wherein, first conductive pin 21 and/or second conductive pin 22 can be connected with lead 23 by rivet 25, for example, can adopt self-plugging rivet to realize; Perhaps also can adopt pin-and-hole to be connected with lead 23, for example, the middle aperture that first conductive pin 21 and second conductive pin 22 can be set is slightly larger than the diameter of lead 23, during installation lead 23 is penetrated in the hole of conductive pin, then the afterbody of conductive pin is pressed into slightly flat shape and clamps lead 23 both are reliably connected.
Secondly, the connection structure that conductive mechanism and hole for injecting glue are described is as follows: the diameter in second hole on the following liner plate 17 can be slightly larger than the head diameter of second conductive pin 22, less than the base diameter of second conductive pin 22 and the diameter of cavity, the head of second conductive pin 22 passes from this second hole.
The slightly larger in diameter in first hole on the last liner plate 16 is in the base diameter of first conductive pin 21 and the diameter of the cavity in the rubber layer.First conductive pin 21 is directly put into from this first hole.At this moment, a packaged unit 26 can be set, this packaged unit 26 is connected with the sealing of first hole, is about to first hole and blocks, and with realization whole conductive mechanism is enclosed in the hole for injecting glue.
Concrete, can be provided with the 3rd hole by this packaged unit 26, the diameter in this 3rd hole is greater than the head diameter of first conductive pin 21, less than the base diameter of first conductive pin 21, for example, the diameter in the 3rd hole can be set to identical with the diameter in second hole on the following liner plate.The head of first conductive pin 21 passes from the 3rd hole, and the base of first conductive pin 21 is pushed down in the lower surface of this packaged unit, thereby conductive mechanism is enclosed in the hole for injecting glue.
This packaged unit 26 can with first hole between be connected by engage thread, this moment this packaged unit be a screw plug.For example, the outside face of packaged unit 26 is provided with outside thread, the cavity diameter of this externally threaded slightly larger in diameter in rubber layer; First hole is that tapped bore is a negative thread, and the slightly larger in diameter of this tapped bore is in the base diameter of first conductive pin 21.Packaged unit 26 can be screwed in first hole and push down first conductive pin 21, can be subjected to stopping of rubber layer and stop fastening when packaged unit 26 is screwed onto certain depth.Perhaps, packaged unit 26 also can with first hole between be connected by interference assembling.The inside face that is first hole of the outside face of packaged unit 26 and last liner plate 16 is not made screw thread, still, makes the external diameter of packaged unit 26 be slightly larger than the internal diameter in first hole, can adopt the pressure assembling to compress during assembling and can keep.
Further, can also be affixed on last liner plate 16 a retaining pad 27, this retaining pad 27 can be for being welded on the liner plate 16, and between the base of the lower surface of packaged unit 26 and first conductive pin 21.This retaining pad 27 is set, can prevents liner plate 16 and packaged unit 26 may occur when relatively thin and be connected unstable problem with last liner plate, the effective thickness of liner plate on can increasing, the connection of further reinforcing packaged unit.For example, after retaining pad 27 was set, packaged unit 26 can all be threaded with first hole and this retaining pad 27, thus can so that between liner plate 16 and the packaged unit 26 be connected more reliable.
Describe the making and the use of the axle box rubber pad of present embodiment below in detail, wherein, lead is example with the copper stranded conductor:
At first, can carry out the assembling of conductive mechanism.During assembling, can at first second conductive pin 22 be connected with copper stranded conductor, connection can adopt self-plugging rivet to realize.The spring 24 that will support usefulness then is inserted in copper stranded conductor, because the base diameter of second conductive pin 22 is greater than the internal diameter of spring 24, so spring 24 can be stuck on the base of second conductive pin 22 can not deviate from.Compression spring 24 is connected first conductive pin 21 with copper stranded conductor, connect also to adopt self-plugging rivet to realize that like this, above-mentioned first conductive pin 21, second conductive pin 22, copper stranded conductor and spring 24 are just formed a conductive mechanism.
Then, offer hole for injecting glue and carry out injecting glue sulfuration.Before axle box rubber pad sulfuration, can be in advance open i.e. second hole of a circular hole at the middle part of liner plate 17 down, the slightly larger in diameter in this second hole is in the head diameter of second conductive pin 22 and less than its base diameter.Also offer for example tapped bore of one first hole at the middle part of last liner plate 16, the slightly larger in diameter of this tapped bore is in the base diameter of first conductive pin 21.In the curing process of axle box rubber pad, the tapped bore that can utilize liner plate 16 middle parts adopts a slightly larger in diameter to be slightly less than the press-on pins pressure injection of tapped bore diameter in first conductive pin, 21 bases as hole for injecting glue during injecting glue.Injecting glue downstream pressure pin is pressed in the tapped bore of last liner plate 16 and directes reach down liner plate 17 after cure of pressurizeing.After sulfuration is finished, it is a slightly larger in diameter in the base of first conductive pin 21 and second conductive pin 22 that the middle part of rubber layer has just formed a middle part, be slightly less than the structure of cylindrical cavity of the tapped bore of liner plate 16, be threaded the hole on the last liner plate 16 of corresponding position, have circular hole on the following liner plate 17.
Then, conductive mechanism is packed in the hole for injecting glue.The conductive mechanism that installs is penetrated from the tapped bore of last liner plate 16, the head that makes second conductive pin 22 promptly passes second hole from the circular hole of liner plate 17 down, and the packaged unit that adopts i.e. the 3rd hole (its diameter can be identical with second hole at following liner plate 17 middle parts) with holes, a middle part then for example screw plug is screwed in the tapped bore at liner plate 16 middle parts and pushes down first conductive pin 21.At this moment rubber layer 18 is compressed, and when screw plug is screwed onto certain depth, because the diameter of cavity is slightly less than the external thread diameter of screw plug, makes screw plug will be subjected to stopping of rubber layer 18 and stops.In addition, in assembling, can design by suitable dimensions, make the outside face of the end face of second conductive pin 22, make the outside face of the end face of first conductive pin 21 a little more than the thin layer rubber that upper surface vulcanized of last liner plate 16 a little more than the thin layer rubber that lower surface vulcanized of following liner plate 17.
Further, locating dowel pin 28 can be provided with or not be provided with according to concrete structure needs as the locations between axle box rubber pad and bogie side frame and adapter.In addition, the retaining pad 27 that is welded on the liner plate 16 can increase effective thickness, make to go up between liner plate 16 and the screw plug be connected more reliable.
When the axle box rubber pad of present embodiment used, the axle box rubber pad was assembled between bogie side frame and the adapter, and the head end of first conductive pin of this axle box rubber pad contacts with bogie side frame, and the head end of its second conductive pin contacts with adapter.As shown in Figure 5, because the head end of first conductive pin 21 is higher than the thin layer rubber of liner plate upper surface, the head end of second conductive pin 22 is higher than the thin layer rubber of liner plate lower surface down, and therefore, these two conductive pins will be subjected to the pressure effect of bogie side frame and adapter.Owing to outwards supports by in-to-in spring 24 between two conductive pins, so spring 24 is compressed, and the inside retraction axle box of two conductive pins rubber pad inside is till the head end of conductive pin and the surface of liner plate up and down are fair.Spring 24 has been subjected to compression, the support reaction that is produced acts on two conductive pins, two conductive pins are outwards pressed on bogie side frame and the adapter, thereby make conductive pin keep reliably contacting with bogie side frame and adapter, no matter at vehicle stationary state or travel condition of vehicle, the axle box rubber pad all is that so this axle box rubber pad has just been realized bogie side frame and adapter bonded assembly conducting function like this when being subjected to vertical compression and transverse and longitudinal shearing force generation distortion.
The axle box rubber pad of present embodiment, by built-in conductive mechanism in the hole for injecting glue of axle box rubber pad, utilize the both ends of the surface of conductive mechanism to contact with adapter with bogie side frame respectively, solve axle box rubber pad that the liner plate surface that exists in the prior art is provided with thin layer rubber and can not realize the problem of conducting function simultaneously, it is high and easily produce abrasion, easily and the deficiency of bogie side frame and adapter bad contact to make that the axle box rubber pad can overcome up and down liner plate accuracy of manufacture requirement, can realize conducting function again.
