Abstract
The utility model relates to an air duct structure of an electrical locomotive pantograph slipper; a copper pipe (2) has a straight S-shaped bending (3) at a position close to a gas nozzle (1); and shape and size of the bending makes the root portion of the copper pipe perpendicular to the gas nozzle when the gas nozzle is inserted into a gas nozzle hole. The air duct of the pantograph slipper enables the gas nozzle to be easily inserted into the gas nozzle hole of an aluminium holder in assembly without applying an active force to lead deformation of the copper pipe, thus avoiding the stress at a welding position of the copper pipe and the gas nozzle, preventing cracking here, reducing waste product, and more importantly preventing the safety potential in traveling when the product having micro-cracks is assembled on the locomotive.
Description
Technical field
The utility model relates to a kind of pantograph pan of use for electric locomotive, particularly a kind of electric locomotive pantograph sliding plate that falls the bow device automatically that is applicable to.
Background technology
Pantograph pan is the critical component of electric locomotive operation.In the locomotive operation process, pantograph pan contacts with contact system and has a high-revolving relative motion, during constantly be subjected to the high speed impact and the frequent vibration of contact system.The equivalent damage problem in case breaking appears in slide plate, rent intensity descends significantly, and under the condition of the continuous shock and vibration of contact system, very easily cracked the coming off in edge forms a groove.Contact system is caused the damage of bow, net easily by card when locomotive is turned, and produces serious safety misadventure.
For avoiding above-mentioned situation, electric locomotive now adopts a kind of bow system of falling automatically of pantograph.The groundwork of falling the bow system automatically is that an air flue is set in slide plate, supplies pressurized air from pantograph to it by air supply system.When slide plate broke, pressurized air was leaked from the slide plate air flue, and fast prompt drop bow valve will be got rid of the air in the pantograph lifting apparatus, realize fast prompt drop bow, that is to say, slide plate breaks and causes the pressurized air in the air flue to leak, and falls bow automatically and just can realize.
Change an angle and say that when slide plate was kept perfectly zero defect in assembling, detection or operational process, air flue should keep gas tightness, should not produce the problem of leakage, otherwise will produce the maloperation of falling the bow system automatically.
But in the assembling process of slide plate, as shown in Figure 3, in the air passage structure of prior art, copper pipe 2 is linearities, and is inserted in the valve 1, then in copper pipe 2 and valve 1 bonded assembly root weld, and guarantees that welding is air tight.This air flue is walked around the opening 5 of aluminium holder with copper pipe 2 when slide plate is assembled, valve 1 is inserted in the air nozzle hole 4 of aluminium holder.Because copper pipe 2 is linearities, and imbed fully below the aluminium holder upper surface behind the air nozzle hole 4 of valve 1 insertion aluminium holder, copper pipe 2 is on the aluminium holder upper surface.When assembling, must firmly valve 1 be inserted air nozzle hole 4 like this, then it be fixed from aluminium holder lower surface with nut.In this assembling process,, therefore make copper pipe 2 and valve 1 junction be subjected to big stress because copper pipe 2 distortion could be inserted valve 1 in the air nozzle hole 4 fully.Though copper pipe 2 and valve 1 weld together because copper pipe 2 is thinner, firmly make weld crack in the assembling process easily.When detecting the air flue leak tightness after assembling, big crackle will leak gas, and makes slide plate become waste product.Sometimes crackle is small, and naked eyes can't find, even does not also see gas leakage when detecting, but is contained in when using on the locomotive, because various applying working conditions such as vibrations, crackle causes very fast expansion gas leakage in advance produce and falls bow automatically, buries potential safety hazard from driving.
Summary of the invention
The utility model provides a kind of air passage structure of electric locomotive pantograph sliding plate, is used to overcome above deficiency.
Pantograph pan air passage structure of the present utility model is characterized in that copper pipe in the bending that a straight S shape is arranged near the valve place, the vertical valve of copper pipe root when the shape and size of this bending make valve insert air nozzle hole.
Pantograph pan air flue of the present utility model, can when assembling, valve easily be inserted in the air nozzle hole of aluminium holder, do not make the copper pipe distortion and do not need to apply application force, therefore avoided the stress of copper pipe and valve weld, can prevent cracking herein, reduce waste product, the more important thing is that the product that prevents tiny crack is assembled on the locomotive, causes traffic safety hidden danger.
Description of drawings
Fig. 1 is the viewgraph of cross-section of slide plate;
Fig. 2 is the birds-eye view of slide plate aluminium holder;
Fig. 3 is the air passage structure of prior art;
Fig. 4 is an air passage structure of the present utility model.
The specific embodiment
The utility model is described with reference to the accompanying drawings.
Fig. 1 is the viewgraph of cross-section of slide plate, and wherein 11 is the carbon bar, and 12 is tack coat, and 13 is air flue, and 14 is the aluminium holder.Fig. 2 is the birds-eye view of aluminium holder, shown the aluminium holder symmetry half, wherein 4 is air nozzle hole, the 5th, opening.Fig. 3 is the pantograph air passage structure of prior art, and wherein 1 is valve, and 2 is copper pipe.
Fig. 4 is a pantograph air passage structure of the present utility model, and wherein 1 is valve, the 2nd, and copper pipe, the 3rd, bending.Of the present utility modelly be characterised in that bending 3, it is in the bending that a straight S shape is arranged near the valve place.The aluminium thickness of air nozzle hole 4 in the shape and size of this bending and the aluminium holder and opening 5 and aluminium holder adapts, the bottom surface 6 of copper pipe 2 is concordant with the end face 7 of valve 1, the length L of dogleg section equals the length S of aluminium holder opening 5, thus the vertical valve of copper pipe root when making valve insert air nozzle hole.
Pantograph pan air flue of the present utility model, can when assembling, valve easily be inserted in the air nozzle hole of aluminium holder, do not make the copper pipe distortion and do not need to apply application force, therefore avoided the stress of copper pipe and valve weld, can prevent cracking herein, reduce waste product, the more important thing is that the product that prevents tiny crack is assembled on the locomotive, causes traffic safety hidden danger.
Claims (2)
1. the air passage structure of an electric locomotive pantograph sliding plate is characterized in that copper pipe (2) locating straight S shape bending (3) near valve (1).
2. air passage structure according to claim 1 is characterized in that the bottom surface (6) of copper pipe (2) is concordant with the end face (7) of valve (1), and the length (L) of bending (3) equals the length (S) of aluminium holder opening (5).
