The utility model discloses a device, high-speed train are at the driving in-process, and the pantograph slide makes the contact point continuous change of pantograph slide and contact net because linear electric motor's the reciprocating motion of doing of drive, has avoided the excessive wearing and tearing of pantograph slide fixed position and the wearing in advance that leads to, uses the sharp contact net of following the rail direction and setting up simultaneously, has reduced the length of contact net copper line, has avoided the waste of copper product.
Description
Technical Field
The utility model belongs to the technical field of high-speed train corollary equipment, a electrodynamic type high-speed train pantograph system is related to.
Background
Because the high-speed railway has high running speed (the running speed per hour is more than 250 km during design and the initial operation speed per hour is more than 200 km), the high-speed railway needs the support of a series of matching technologies, such as a road network and a signal system suitable for the high-speed railway, a high-speed pantograph, a high-speed bogie, a vehicle body conforming to dynamic performance and the like, wherein the pantograph is used as a current-collecting device of a locomotive and plays a significant role in a pantograph system.
In the running process of a high-speed train, the relative friction between the pantograph slide plate and the contact net can lead to the pantograph slide plate to be worn out quickly, so that the service life of the pantograph slide plate is shortened, the pantograph slide plate is generally made of graphite and has low hardness, the contact net is generally made of copper alloy and has high hardness. In order to solve the problem, at present, a contact net is erected above a high-speed train track along the track in a Z-shaped erecting mode, and compared with the contact net erected linearly along the track, the Z-shaped contact net is relatively lengthened in line length, so that more raw material copper is consumed.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an electrodynamic type high-speed train pantograph system, when having solved the pantograph slide that exists among the prior art and contact net contact, the wear and tear of pantograph slide is inhomogeneous leads to the life-span to reduce to and erect "Z" style of calligraphy contact net along the track and lead to the extravagant problem of copper product material.
The utility model adopts the technical proposal that the electric high-speed train pantograph system comprises a pantograph slide plate, the pantograph slide plate is connected with a linear motor in a driving way downwards, and the linear motor is arranged on the upper surface of a bracket; the support still articulates simultaneously with upper arm pole upper end, balancing pole upper end respectively, and upper arm pole lower extreme articulates respectively has pull rod, underarm pole, and the other end of pull rod, underarm pole is articulated with the chassis simultaneously, and the balancing pole lower extreme is articulated with underarm pole upper portion.
The utility model discloses an electrodynamic type high-speed train pantograph system, its characterized in that still lies in:
the underframe is arranged on the roof of the traction locomotive through a plurality of insulators.
The pantograph slide plate, the upper arm rod and the lower arm rod are all made of conductive materials.
The pantograph slide plate, the upper arm rod and the lower arm rod are sequentially connected with an integrated conductor.
The linear motor is matched with a steering controller.
The beneficial effects of the utility model are that, high-speed train is at the driving in-process, and the reciprocating motion that the pantograph slide was done under linear electric motor's drive makes the contact point continuous change of pantograph slide and contact net, has avoided the excessive wearing and tearing of pantograph slide fixed position and the contact net that leads to worn in advance, uses the contact net of following the straight line of rail direction and erects simultaneously, has reduced the length of contact net copper line, has avoided the waste of copper product.
Drawings
Fig. 1 is a schematic structural diagram of the device of the present invention.
In the figure, 1, a bracket, 2, a linear motor, 3, a pantograph slide plate, 4, an upper arm rod, 5, a pull rod, 6, an insulator, 7, an underframe, 8, a lower arm rod and 9, a balance rod are arranged.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, the device of the utility model has the structure that the device comprises a pantograph slide plate 3, the pantograph slide plate 3 is connected with a linear motor 2 in a downward driving way, and the linear motor 2 is arranged on the upper surface of a bracket 1; the support 1 is also respectively articulated with 4 upper ends of upper arm poles, the 9 upper ends of balancing pole simultaneously, and 4 lower extremes of upper arm poles are articulated respectively have pull rod 5, underarm pole 8, and the other end of pull rod 5, underarm pole 8 is articulated with chassis 7 simultaneously, and 9 lower extremes of balancing pole are articulated with 8 upper portions of underarm pole, and chassis 7 is installed on the roof of traction engine through a plurality of insulators 6.
The linear motor 2 is matched with a steering controller, so that the linear motor 2 can move back and forth repeatedly.
The pantograph slide plate 3, the upper arm rod 4 and the lower arm rod 8 are all made of conductive materials and are sequentially connected with an integrated conductor.
The upper arm rod 4 and the lower arm rod 8 are both made of aluminum seamless tubes and play a role in supporting and conducting current. The pantograph pan 3 is typically made of metal impregnated carbon (85HS) or pure carbon (60-100 HS). Pantograph slide 3 contacts with the contact net, conducts to the consumer of high-speed train through upper arm pole 4, lower arm pole 8 again to the frictional contact through pantograph slide 3 and contact net obtains the electric energy for the high-speed train.
The working process of the device of the utility model is that,
referring to fig. 1, when a high-speed train starts to run, a linear motor 2 is started, the linear motor 2 drives a pantograph slide plate 3 to do reciprocating motion, and the linear motor 2 drives the pantograph slide plate 3 to do reciprocating motion, so that reliable contact between the pantograph slide plate 3 and an overhead line system is ensured, and the relative contact position between the pantograph slide plate 3 and the overhead line system is continuously changed, so that the pantograph slide plate is prevented from being worn out in advance due to excessive abrasion of a fixed position of the pantograph slide plate; meanwhile, a linear contact net is erected along the rail direction, the length of a contact net copper wire is reduced, and waste of copper materials is avoided.
