Description
Technical field
A kind of a kind of the present invention relates to pantograph, more particularly to double-standard (main line railway, subway light rail) high speed pantograph
Use bow.
Background technology
Pantograph is the equipment that contact net provides the energy to main line railway train, metro and light rail vehicle.As vehicle is in fortune
Contact with contact net in row, the dynamic characteristic requirement to pantograph is very high, and bow is the critical component of pantograph, it is desirable to pantograph
Simple structure, lightweight, small volume, air dynamic behaviour are good.
Operation demand under two kinds of contact net voltages of DC1500V and AC25KV is needed for intercity EMUs, because net pressure
Difference, main line railway operation rated current is general maximum to be less than 500A, and subway light rail pantograph operation rated current is general
For 1500A, be guarantee can high current operation on subway and light-rail vehicles, also can guarantee that the high-speed cruising on main line railway,
Existing frequently-used mode is to increase the width of carbon slipper, and the slide plate to pure carbon carries out leaching Copper treatment, increases flow conductivity, but same
When bow weight increase, on pantograph spring spring, normalized wave function increases, therewith pantograph power performance and with net hydraulic performance decline, nothing
Method adapts to the requirement of high-spe-ed trunk line railway operation.
Content of the invention
It is an object of the invention to provide a kind of situation that both can be suitably used for main line railway EMUs high-speed cruising, can also be suitable for
Double-standard high speed pantograph bow in the service requirement of subway light rail pantograph high current.
The purpose of the present invention is achieved through the following technical solutions：
The double-standard high speed pantograph bow of the present invention, including bow, the left end of the bow is left equipped with bow in parallel
End supports assembling, and the right-hand member of the bow supports assembling equipped with bow right-hand member in parallel, the bow left end support assembling in parallel and
Bow right-hand member in parallel supports the both sides of assembling to be respectively provided with two carbon slippers, and the middle part of the bow is equipped with push pipe on bow, institute
The two ends for stating push pipe on bow are respectively provided with power transmission stigma.
As seen from the above technical solution provided by the invention, double-standard high speed pantograph provided in an embodiment of the present invention
With bow, can be not only used for main line railway, can be used for subway light rail, simple structure, lightweight, small volume, aerodynamic
Characteristic is good.Adapting to intercity EMUs needs operation demand under two kinds of contact net voltages of DC1500V and AC25KV, you can with
AC25KV can also be in DC1500V net pressure operations.
Description of the drawings
Fig. 1 is the three dimensional structure diagram of double-standard high speed pantograph bow provided in an embodiment of the present invention.
Fig. 2 is the structural design drawing that the bow in the embodiment of the present invention supports assembling
Specific embodiment
Accompanying drawing in reference to the embodiment of the present invention, to the embodiment of the present invention in technical scheme carry out clear, complete
Ground description, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiment.Based on this
Inventive embodiment, the every other enforcement obtained under the premise of creative work is not made by those of ordinary skill in the art
Example, belongs to protection scope of the present invention.
The double-standard high speed pantograph bow of the present invention, its preferably specific embodiment is：
Including bow, equipped with bow left end support assembling in parallel, the right-hand member of the bow is equipped with simultaneously for the left end of the bow
Connection bow right-hand member supports assembling, the bow left end support assembling in parallel and bow right-hand member in parallel to support the both sides of assembling to fill respectively
There are two carbon slippers, equipped with push pipe on bow, the two ends of push pipe are respectively provided with force-transmitting pole on the bow at the middle part of the bow
Head.
The bow left end support assembling in parallel and bow right-hand member in parallel support assembling to include that bracket is assembled respectively, the support
The both sides of frame assembling are respectively provided with long arch head bracket and short arch head bracket, and the middle part of the bracket assembling is equipped with stopping means and support
Pipe, is connected to extension spring between the stopping means and long arch head bracket and short arch head bracket.
The two ends of the extension spring are provided with oscillating bearing.
The bracket group at the outer end position of the extension spring is loaded onto equipped with spacer sleeve.
The double-standard high speed pantograph bow of the present invention, is that solution subway light rail pantograph operation rated current is larger
Problem arranges 4 carbon slippers, increases the flow conductivity of pantograph collector head.Relative to two slide plate bow structures, increasing slide plate number
While amount, (increase flow conductivity) ensures that normalized wave function is constant on every extension spring spring, it is ensured that pantograph is in high-speed cruising
Dynamic performance does not change.Can be not only used for main line railway, can be used for subway light rail, simple structure, lightweight, volume
Little, air dynamic behaviour is good.Adapting to intercity EMUs needs to run under two kinds of contact net voltages of DC1500V and AC25KV
Demand, you can also run in DC1500V net pressures in AC25KV.
It is 4 that parallel bow supports the corresponding extension spring of assembling (left/right), using helical spring or other are linear
Spring.Every spring is linked with position-limit mechanism (fixing end) and long/short bow bracket (shift end) respectively by oscillating bearing, real
Damping during existing high-speed cruising.
The parallel bow supports the corresponding bracket assembling of assembling (left/right), spacer sleeve, stopping means, trustship have
Effect increases stress surface of the pantograph in high-speed cruising, and strengthen bow bears alternate load even load stressing conditions.
The present invention is further described with example below in conjunction with the accompanying drawings.
As shown in figure 1, for the structural representation of the present invention, by bow 1, bow left end support assembling 2, carbon slipper 3 in parallel,
On power transmission stigma 4, bow, push pipe 5, bow right-hand member in parallel support assembling 6 to constitute.
2 bows 1 are connected with bow trustship by securing member, and the bow trustship other end is by power transmission stigma 4 and bow
Push pipe 5 connects.4 carbon slippers 3 are respectively arranged in bow left end support assembling 2 in parallel by bolt thereon and bow in parallel is right
End supports assembling 6.
As shown in Fig. 2 parallel bow supports assembling, its structure to include the assembling 8, extension spring of long arch head bracket 7, bracket
9th, trustship 11, stopping means 10, short arch head bracket 12, oscillating bearing 13, spacer sleeve 14.Extension spring two ends are provided with joint shaft
Hold, oscillating bearing one end is connected to long arch head bracket two ends, and one end is connected on stopping means.Carbon slipper is by connecting bolt point
Arch head bracket fit on is not installed on, and pantograph collector head can pass through extension spring when vertical impact or vertical deviation is subject to
Stretching action, reduces vibration and impact of the pantograph in high-speed cruising.
The parallel bow supports the corresponding bracket assembling of assembling (left/right), spacer sleeve 14, stopping means 10, trustship
11 can be effectively increased stress surface of the pantograph in high-speed cruising, and strengthen bow bears alternate load even load stressing conditions.
The above, the only present invention preferably specific embodiment, but protection scope of the present invention is not limited thereto,
Any those familiar with the art in the technical scope of present disclosure, the change or replacement that can readily occur in,
Should all be included within the scope of the present invention.Therefore, protection scope of the present invention should be with the protection model of claims
Enclose and be defined.
