Description
Technical field
The utility model relates to electric locomotive technical field, especially a kind of pantograph pan.
Background technology
Pantograph pan is that electrically-driven car obtains the electrical equipment of electric energy from contact system, be arranged on locomotive or motor-car roof, pantograph pan obtains electric energy by contacting with contact system, in train driving process, to be subject to force of sliding friction larger for pantograph pan, wearing and tearing can be produced, reduce slide plate service life, need often to change, extremely inconvenient.
Summary of the invention
In order to overcome the technical deficiency that there is larger friction force between current pantograph pan and contact system, the utility model provides a kind of pantograph pan, this pantograph pan is by the design to powered bow scheme, slide plate is replaced with roller device, the friction force between current-collecting device and contact system can be reduced, the service life of extension fixture.
The utility model solves the technical scheme that its technical matters adopts: a kind of pantograph pan, comprises cylinder, cylinder axle, bearing, roller bearing end cap, base, bearing adapter plate, steel band, pure carbon ribbon; Base is H type, and base two upper lateral part respectively has three bearing adapter plates, and cylinder axle is inserted in centre of the drum hole, and cylinder axle is fixed on bearing adapter plate by bearing, installs roller bearing end cap outside bearing, and three cylinder surfaces install steel bands, and steel strip surface bonds the pure carbon ribbon of one deck.
Described bearing is rolling bearing units, main body is a hollow cylinder, and inside is used for fixing an axle, and periphery has a tapped bore, be used for bearing oil injecting lubricating, screw in screw at ordinary times, bottom is an oblong square piece, and respectively there is a tapped bore at square piece two ends, be fixed by screws on bearing adapter plate, each base has three bearings, has two tapped bore outside cylinder, installs roller bearing end cap.
Described bearing adapter plate is fixed on base by welding manner, and respectively there is a tapped bore both sides.
Described cylinder material is that carbon steel is zinc-plated, and fixed form is axis pin-and-hole formula, and there is through hole at center, and coordinate cylinder axle to fix, three cylinders, are in same level height.
Described pure carbon ribbon is fixed on steel band by adhesive agent, and steel band is steel article.
The intermediate bar of described base is connected with pantograph bracket, and there is protection air flue junction, when roller device reaches operating limit or has a greater impact with contact system, can start pantograph and fall bow device.
When electrically-driven car travels, replace former arc slide plate with roller device, friction mode transfers friction of rolling to by cliding friction, and contact zones drive cylinder to rotate together after being subject to the friction force of contact system, and friction force is reduced.
The beneficial effects of the utility model are, a kind of pantograph pan, and this pantograph pan, by design to powered bow scheme, is replaced slide plate with roller device, can be reduced the friction force between current-collecting device and contact system, extension fixture service life.
