Description
Technical field
The present invention relates to a kind of pantograph more particularly to a kind of double-standard (main line railway, subway light rail) high speed pantographs
Use bow.
Background technique
Pantograph is equipment of the contact net to main line railway train, the metro and light rail vehicle offer energy.Since vehicle is being transported
It is contacted in row with contact net, very high to the dynamic characteristic requirement of pantograph, bow is the critical component of pantograph, it is desirable that pantograph
Structure is simple, light-weight, small in size, and air dynamic behaviour is good.
The operation demand under two kinds of contact net voltages of DC1500V and AC25KV is needed for intercity EMU, because of network pressure
Difference, main line railway runs that rated current is general maximum to be no more than 500A, and it is general that subway light rail pantograph runs rated current
For 1500A, for guarantee can the high current operation on subway and light-rail vehicles, also can guarantee the high-speed cruising on main line railway,
Existing frequently-used mode is the width for increasing carbon slipper, and carries out leaching Copper treatment to the slide plate of pure carbon, increases flow conductivity, but same
When bow weight increase, normalized wave function increases on pantograph spring spring, pantograph power performance and declines therewith with net performance, nothing
The requirement of method adaptation high-spe-ed trunk line railway operation.
Summary of the invention
The case where both having can be suitably used for main line railway EMU high-speed cruising the object of the present invention is to provide one kind, can also be applicable in
In the double-standard high speed pantograph bow of the service requirement of subway light rail pantograph high current.
The purpose of the present invention is what is be achieved through the following technical solutions:
Double-standard high speed pantograph bow of the invention, including bow, it is left that the left end of the bow is equipped with bow in parallel
End support assembly, the right end of the bow are equipped with bow right end support assembly in parallel, the parallel connection bow left end support assembly and
The two sides of bow right end support assembly in parallel are respectively provided with two carbon slippers, and the middle part of the bow is equipped with push pipe on bow, institute
The both ends for stating push pipe on bow are respectively provided with power transmission column cap.
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, it can be not only used for main line railway, can be used for subway light rail, structure is simple, light-weight, small in size, aerodynamics
Characteristic is good.It adapts to intercity EMU and needs the operation demand under two kinds of contact net voltages of DC1500V and AC25KV, it can
AC25KV can also be in DC1500V network pressure operation.
Detailed description of the invention
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 of the bow support assembly in the embodiment of the present invention
Specific embodiment
With reference to the attached drawing in the embodiment of the present invention, technical solution in the embodiment of the present invention carries out clear, complete
Ground description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on this
The embodiment of invention, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, belongs to protection scope of the present invention.
Double-standard high speed pantograph bow of the invention, preferable specific embodiment is:
Including bow, the left end of the bow is equipped with bow left end support assembly in parallel, and the right end of the bow is equipped with simultaneously
Join the support assembly of bow right end, the parallel connection bow left end support is assembled and the two sides of bow right end support assembly in parallel fill respectively
There are two carbon slippers, the middle part of the bow is equipped with push pipe on bow, and the both ends of push pipe are respectively provided with force-transmitting pole on the bow
Head.
The parallel connection bow left end support assembly and bow right end support assembly in parallel respectively include bracket assembling, the support
The two 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 limiting device and support
Pipe, is connected separately with extension spring between the limiting device and long arch head bracket and short arch head bracket.
The both ends of the extension spring are equipped with oscillating bearing.
The bracket group at the outer end position of the extension spring is loaded onto equipped with spacer sleeve.
Double-standard high speed pantograph bow of the invention, it is biggish to solve subway light rail pantograph operation rated current
4 carbon slippers are arranged in problem, increase the flow conductivity of pantograph collector head.Relative to two slide plate bow structures, increasing slide plate number
(increase flow conductivity) while amount and guarantee that normalized wave function is constant on every extension spring spring, guarantees pantograph in high-speed cruising
Dynamic performance does not change.It can be not only used for main line railway, can be used for subway light rail, structure is simple, light-weight, volume
It is small, air dynamic behaviour is good.Intercity EMU needs are adapted to run under two kinds of contact net voltages of DC1500V and AC25KV
Demand, it can AC25KV can also be in DC1500V network pressure operation.
The corresponding extension spring of parallel bow support assembly (left/right) is 4, and 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 when existing high-speed cruising.
Parallel bow support assembly (left/right) bracket assembling, spacer sleeve, limiting device, the trustship accordingly can have
Effect increases stress surface of the pantograph in high-speed cruising, enhances the load stress condition such as receiving alternating load of bow.
Invention is further explained with example with reference to the accompanying drawing.
As shown in Figure 1, be structural schematic diagram of the invention, by bow 1, bow left end support in parallel assembly 2, carbon slipper 3,
Push pipe 5,6 composition of bow right end support assembly in parallel on power transmission column cap 4, bow.
2 bows 1 are connect by fastener with bow trustship, and the bow trustship other end passes through on power transmission column cap 4 and bow
Push pipe 5 connects.4 carbon slippers 3 are respectively arranged in bow left end support assembly 2 in parallel by bolt thereon and bow in parallel is right
End support assembly 6.
As shown in Fig. 2, parallel bow support assembly, structure includes long arch head bracket 7, bracket assembling 8, extension spring
9, trustship 11, limiting device 10, short arch head bracket 12, oscillating bearing 13, spacer sleeve 14.Extension spring both ends are equipped with joint shaft
It holds, oscillating bearing one end is connected to long arch head bracket both ends, and one end is connected on limiting device.Carbon slipper passes through connection bolt point
It is not installed on arch head bracket fit on, pantograph collector head can pass through extension spring when by vertical impact or vertical deviation
Stretching action reduces vibration and impact of the pantograph in high-speed cruising.
Parallel bow support assembly (left/right) the bracket assembling, spacer sleeve 14, limiting device 10, trustship accordingly
11 can effectively increase stress surface of the pantograph in high-speed cruising, enhance the load stress condition such as receiving alternating load of bow.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
