Description

A kind of high speed pantograph bow
Technical field
The present invention relates to a kind of pantograph collector head, particularly relate to a kind of high speed pantograph bow.
Background technology
On the vehicles such as the electric locomotive in electrified railway and urban track traffic, motor train unit or driven operating vehicle, all need use pantograph on contact system, to get stream.Electric traction is adopted in electrified railway; Train is under state of kinematic motion; Utilize pantograph to obtain electric energy,, must guarantee the absolute reliable and uninterrupted of power supply for guaranteeing train smooth, safe operation from contact system; Be pantograph receive stream mode good, otherwise will influence the operation of train and the performance of electrical drive system.Under the high-speed cruising state, higher to the requirement of pantograph.
For guaranteeing that bow net has the good properties of flow that receives, the structure of pantograph collector head is very crucial.The bow structure of existing pantograph is: 2 spring brackets are arranged at the two ends of slide plate, and these spring brackets are made up of coil spring, wire rack or spring case usually, also by the employing torsion spring form support.These spring bracket complex structures, weight is bigger, and the following property of pantograph has been brought adverse effect.The design that also has laminated spring as the bow support, but it is big slightly also to show volume.Be unfavorable for dynamically being flowed under the high-speed condition.
Summary of the invention
Technical matters to be solved by this invention provides a kind of features simple structure, and is in light weight, the high speed pantograph bow that aerodynamic characteristics is good.
In order to solve the problems of the technologies described above; High speed pantograph bow provided by the invention; Comprise the slide plate and the first longbow angle, the bottom of described slide plate is connected with the front end of two frame springs, and the rear end of two described frame springs all is fixed on the hinge of described pair of bar upper frame; The two ends of described slide plate are equipped with little bow angle, and the described first longbow angle is fixed in the hinge of described pair of bar upper frame.
The shape in the cross section of described slide plate is streamline contour; The bottom of described slide plate is the skateboards slot of a strip shape; Described skateboards slot is embedded with a carbon slide block or partial metallurgy slide block; Described skateboards slot links to each other with carriage with screw, and described carriage is connected with bearing with pin, and the front end of described frame spring and described bearing are affixed.
The streamline contour of described slide plate cross-sectional plane is: two limits are straight line up and down, and right ends is oval or circular.
A kind of high speed pantograph bow comprises slide plate, and the central bottom of described slide plate is connected with the front end of a frame spring, and the rear end of described frame spring is fixed on the hinge of single pole upper frame, and the two ends of described slide plate are equipped with the second longbow angle.
The shape in the cross section of described slide plate is streamline contour; The bottom of described slide plate is the skateboards slot of a strip shape; Described skateboards slot is embedded with a carbon slide block or partial metallurgy slide block; Described skateboards slot links to each other with carriage with screw, and described carriage is connected with bearing with pin, and the front end of described frame spring and described bearing are affixed.
The streamline contour of described slide plate cross-sectional plane is: two limits are straight line up and down, and right ends is oval or circular.
Adopt the high speed pantograph bow of technique scheme, the cross sectional shape of slide plate is streamline contour, and the bottom of slide plate is the skateboards slot of a strip shape; Skateboards slot is embedded with a slide block, and this slide block both can be the carbon slide block, also can be other material; Like the partial metallurgy slide block, the below of slide plate is connected with the front end of frame spring through carriage, and the rear end of frame spring is connected with upper frame; If the upper ledge of pantograph is made up of two bars; Then need use 2 frame springs between upper frame and slide plate, to connect, little bow angle is used at the slide plate two ends, if the pantograph upper frame is a single pole; Then will be the cancellation of the longbow angle, upper end of upper frame, the little bow angle on the slide plate changes the longbow angle into.Under the cooperation of pantograph trammel beam, it is parallel with orbit plane that frame spring can remain pantograph pan, adds the regulating action of bracket, and slide plate is contacted with contact wire all the time closely.
Compared with prior art, the invention has the beneficial effects as follows:
One, slide plate is a streamline contour, and more far better than the slide plate aerodynamic characteristics of existing blunt shape, it has not only reduced air resistance, also greatly reduces the excitation that high velocity air brings, and has strengthened the stability of bow.
Two, the spring-loaded that has replaced existing bow with frame spring has been simplified the bow structure of pantograph greatly, and frame spring has in light weight; Plurality of advantages such as equilibrium response is good, and aerodynamic characteristics is good are under the coordination of pantograph upper frame trammel beam; It can remain the horizontal attitude of pantograph pan; Estimate the existing light 3-4 kilogram of pantograph collector head commonly used of this bow ratio, do like this, can improve the following property of pantograph greatly.
Three, frame spring is simple in structure, handling ease, and cost is lower.
Four, adopt the design of little bow angle on the pantograph pan, reduced the slide plate quality, help improving the following property of pantograph.
Five, in the upper frame upper end of pantograph the longbow angle is installed; This longbow angle helps pantograph and when crossing over contact netting twine trouble or anchor end joint, seamlessly transits, and can avoid on slide plate, using the longbow angle to increase the following property reduction that the slide plate quality causes bow simultaneously.
In sum, the present invention is a kind of features simple structure, and is in light weight, the high speed pantograph bow that aerodynamic characteristics is good.Pantograph not only can adapt to the needs that flowed at a high speed after this bow has been installed, and can the better effect of performance on lower conventional railway of speed or urban light rail railway.
