Abstract
Electric locomotive caterpillar static type current-collector belongs to electric locomotive and gets the stream device, it comprises jacking system, be placed on two bearing wheels by the electricity band, bearing wheel rotates around the axle center, the axle center links to each other with upper frame pipe fitting in the jacking system, being flowed carbon brush is pressed in the rotating shaft of bearing wheel, electric current stands the electricity band, bearing wheel, be subjected to electric carbon brush in the electric current lead-in bushing, to flow into locomotive, thereby stream mode is got in the slip that has thoroughly changed existing locomotive, solve two big deadly defects---" impact " and " abrasion " in the existing electric locomotive operation, reached reduction electrified railway operation cost, improve the purpose of electrified railway operation security reliability.
Description
The invention belongs to electric locomotive and get the stream device.
The existing background technology of the present invention is: existing electric locomotive adopts and is subjected to electricity side to get stream from contact system, belong to cliding friction and get stream, because the characteristics of sliding and being flowed, the high speed of bow (pantograph) travels forward, must form mutual friction mutually and impact with net (contact system), friction certainly will cause the abrasion of contact system, impacts just to make accident between pantograph hide constantly among operation, and causes accident between pantograph in weakest link.So both having greatly reduced the service life of equipment, and increased the frequent degree of overhaul of the equipments, and influenced the safe reliability of equipment again, finally is the economic benefit that has had a strong impact on railway operation.Operation experience for many years shows that because the frequent generation of lead abrasion and accident between pantograph, the use of contact system is received the order also will lack for 10 coming year than design life (only being 25 years).
The design's purpose is: get stream mode from the existing electric locomotive of thorough change and start with, solve two big deadly defect-" impacts " and " abrasion " in the existing electric locomotive operation, reduce electrified railway operation cost (investment and maintenance) thereby reach, improve the purpose of the safe reliability of electrified railway operation, simultaneously, also the requirement of current collection device and contact system (will thereupon be improved) is got ready for the electrified railway that adapts to high speed development.
Design plan of the present invention:
1) design philosophy:
Change the electric locomotive slip and be subjected to stream mode to be static relatively electric means (being different from roll mode), thereby eliminate abrasion and impact between bow net.
2) frame mode:
This device is mainly by being subjected to electric band, bearing wheel, jacking system, gets several parts such as the sorrowful and electric current service conductor of stream carbon and forms.
Be placed on two bearing wheels by certain way by electricity band, turn round by same linear velocity with bearing wheel during operation; Bearing wheel rotates around the axle center, the axle center links to each other with jacking system, all can rise and landing with jacking system by electricity band, bearing wheel, and is in operation, before and after the motion of bearing wheel have synchroneity and independence, adapt to contact system under the various states and operational excellence to guarantee to be subjected to the electricity band.Jacking system need be done except upper frame and adapt to the installation be subjected to the electricity band and part improved, all the other mechanisms all can be with reference to existing part.Flowed carbon brush and be pressed in the rotating shaft of bearing wheel, electric current stands electric band, bearing wheel, flowed carbon brush flows into locomotive in the electric current lead-in bushing.Its organization plan: electric locomotive caterpillar static type current-collector, it comprises jacking system (6), be placed on two bearing wheels (3) by electricity band (2), during operation and bearing wheel by the running of same linear velocity, bearing wheel (3) is (4) rotation around the axle center, axle center (4) links to each other with upper frame pipe fitting (5) in the jacking system (6), flowed carbon sorrowful (1) and be pressed in the rotating shaft of bearing wheel (3), electric current stands electricity band (2), bearing wheel (3), is subjected to electrical carbon sorrowful (1) to flow into locomotive in the electric current lead-in bushing.All risen and landing by electricity band (2), bearing wheel (3) with jacking system.Be subjected to electricity band (2) to adopt multi-disc light-weight conducting material hinged or adopt the soft full wafer conductive material of light-duty matter or adopt stalloy or adopt conductive rubber.
3) principle of work:
When locomotive is not got stream, lifting arm is descended, leave lead, when locomotive is got stream, lifting arm is risen, make to be subjected to electricity band upper surface and contact wire to keep excellent contact (using the lifting power with the pantograph same effect to reach this effect) that electric current just can stand electric band, bearing wheel, flowed carbon brush enters locomotive, and existing pantograph functional similarity at these 2.
When locomotive is advanced, support wheel shaft and railcar body to advance with connecting in the same way, because the crawler belt upper surface is given contact wire one positive pressure, when making locomotive operation, wheel and crawler belt are under the static friction force effect of contact wire, to the opposite direction operation of locomotive, its linear velocity is consistent with railcar body running velocity size, like this, guarantee that the crawler belt upper surface has one section (middle parallel portion) to keep relative static with contact wire all the time, thereby guaranteed that locomotive normally gets being subjected to of moving in the stream and do not have abrasion, the nothing impact between electricity band and static contact wire, so both satisfy the requirement of normally getting stream, reached the purpose of the defective that wears away in the radical cure cliding friction and impact again.
The present invention compares with existing background technology, since this device with electric locomotive at present the cliding friction mode of employing change the relative static stream mode of getting of current-collecting device and contact wire into, thereby two big critical defect-abrasion and impact in the electrochemical railway operation have been solved, it has constantly reduced the mutual abrasion between bow net, reduced cost, service expenditure, just greatly reduces the cost of railway operation at the also service life of extension lead and overhaul period thereof greatly; In addition, because static electric means, cushioned in service greatly, thereby improved the safe reliability of electrified railway greatly because the bow net that the high-speed motion contact brings clashes into.These two aspects all will improve the productivity effect of railway operation greatly, and this also is the basic of railway transportation.
