Abstract
The invention discloses a fish belly high speed pantographic slipper which consists of a slide block (1) and a layer board (2). The slide block (1) is fixedly connected to the layer board (2). The fish belly high speed pantographic slipper is characterized in that the middle part of the slipper is wider than both ends, and the cross section of the slipper is ichthyoid. Conventional pantographic slippers are substantially rectangular, in particular double slipper pantographs. For the high speed pantograph, the lighter the slipper is, the better the effect is. The slipper needs to have a certain thickness to increase the wear-resisting property, so that the slipper has enough using time. Therefore, for conventional pantographic slippers, the thickness cannot be increased, so that the cross section of the pantographic slippers is hard to be made ichthyoid. Thus, adverse effect to the aerodynamic performance at high speed is brought. According to the invention, the slipper is designed ichthyoid, so that the thickness of the slipper is effectively reduced. Not only is enough wear-resisting property ensured, but also the cross section is made ichthyoid to effectively improve the flow performance of the net at high speed. In particular, the effect for the single slipper pantograph is especially remarkable.
Description
Technical field
The best power source mode of railway is electric traction, does electrified railway.Electrified railway must have a cover contact system, on the locomotive supporting pantograph will be arranged, to accept the electric energy of contact system.Pantograph and contact system dynamic Contact require pantograph more light better.Especially the bow slide plate of pantograph, it directly contacts with the contact wire of contact system, require especially lightweight, good aerodynamic quality.Content involved in the present invention is the critical component of pantograph---pantograph pan.
Background technology
The technical performance that improves pantograph pan mainly has been subject to the restriction of following several respects: 1. weight wants light; 2. intensity wants high, shock-resistant; 3. abrasion performance, useful life is long as much as possible; 4. good aerodynamic quality, especially high speed pantograph.
Lightweight, require pantograph pan more thin better.Intensity is high, wear-resisting, requires slide plate more abundant better.Abundant slide plate cross-sectional plane is difficult to make swept-out.The aerodynamic performance of non-streamline slide plate is bad, is unfavorable for the operation under the high-speed condition.
At present, no matter be common electric locomotive or motor train unit, the pantograph pan cross-sectional plane on it generally all is rectangle.What have does diamondwise with before and after the slide plate, has some improvement to being subjected to Flow Velocity.But because slide plate thickness is too large, DeGrain.Especially the middle part of slide plate for wear-resisting, thickens much than two ends especially.Therefore, such slide plate, its aerodynamic performance is not good, is difficult to adapt to the growth requirement of current collection at high speed.Moreover, abrasion of pantograph pan is normally local, all concentrates in the scope of slide plate middle part 400mm-600mm.Medial recess after the degree of depth abrasion, both sides upwarp.Can increase the bow oscillating quantity of pantograph during high-speed cruising, increase contact loss rate.
Summary of the invention
Under the condition of the demands such as technical matters to be solved by this invention is not reduce pantograph pan intensity, and is wear-resisting, with the middle part broadening of pantograph pan, cross-sectional plane is made swept-out.Its swept-out shape of cross section is, the upper and lower surfaces of slide plate are linear, about two faces be shaped as parabola shaped or circular arc.
Described slide plate is comprised of slide block and supporting plate.Slide block is formed by the carbon dust sintering usually, or is processed by partial metallurgy.Supporting plate is processed by aluminium section bar usually.Slide block and supporting plate are consolidated.
The reason that traditional pantograph pan middle part thickens is that the zone that contact wire is is mainly worn and torn is the slide plate middle part, thickens the slide plate middle part and can improve the slide plate wear limit, increases the service life.The present invention adopts and widens the slide plate middle part, and with the method for the rubbed surface in the middle part of the increase slide plate, so that the life-span of slide plate is unaffected, intensity is also unaffected.Increase the slide plate width and more be conducive to the slide plate cross-sectional plane is made swept-out, thereby improved aerodynamic performance.
Particularly a kind of pantograph of single slide plate has appearred in the current high speed pantograph world.This pantograph pan can not increase the slide plate overall weight, and the cross-sectional plane of the lower slide plate of the situation of proof strength is done widelyr.To the pantograph pan of this wall scroll, use present technique, it is more smooth that its streamline contour cross-sectional plane can be done, and aerodynamic performance is better.
Compared with prior art, the invention has the beneficial effects as follows:
One, do not reduce the aerodynamic performance that has improved slide plate under the intensity of pantograph and the abrasion resistance condition.Be conducive to improve the Flow Velocity that is subjected to of pantograph.
Two, simple in structure, realize easily on the technique.
Three, the broadening of slide plate middle part is so that slide plate when contacting with contact wire, the contact surface increase.Increase the conductive area of contact wire and pantograph pan, improved the conduction power of pantograph.
Four, the area of contact of increase contact wire and slide plate can also increase contact wire to the anti-torsion moment of slide plate, improves the mechanical stability of pantograph pan.
Even the abrasion of five degree of depth can not make the slide plate middle part cross yet and cave in greatly, and are favourable to current collection at high speed.
In sum, the present invention is a kind of high speed pantograph slide plate simple in structure.Improvement in performance for high speed pantograph will play positive role.
Description of drawings
Fig. 1 is the main structure body scheme drawing of the embodiment of the invention.
Fig. 2 is the birds-eye view of Fig. 1.
Fig. 3 is the cutaway view in A-A cross section among Fig. 2.
The specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing and concrete embodiment.
Guiding theory of the present invention is that former slide plate middle part thickening is converted to the width increase at slide plate middle part, and then does streamline contour at the two ends, the left and right sides of slide plate cross-sectional plane and process.Bake first slide block 1 according to this principle, make again supporting plate 2, then that the two is fixed.Fixed method can be bonding with special glue, also can use screw fastening.
Its horizontal intensity of the slide plate of producing so obviously is to have strengthened.Its vertical intensity, particularly bending strength needs computational analysis, should carry out Experiments of Machanics in case of necessity.Qualified fish belly shape high speed pantograph slide plate should be, mechanical property is not less than former pantograph pan, and aerodynamic performance is also very desirable.
