Abstract
The invention provides an electric locomotive short-distance self-walking device without an external power supply. When an electric locomotive needs to move without the external power supply, a power supply line of the locomotive is converted into a library row position from an operation position, and an electric signal is obtained; the electric signal stimulates an auxiliary power source system in the locomotive; and output power of the auxiliary power source system is used for directly or indirectly driving the locomotive to walk by a short distance. After a locomotive power grid is powered off, an auxiliary energy source of the locomotive is used as an energy source for driving the locomotive to self-walk, so that the problems that after the locomotive loses the external power supply, the locomotive self-walks by the short distance are effectively solved; and in the method, an external auxiliary device does not need to be used for pushing the locomotive and a locomotive inner system is used for self-adjusting completely, so that the auxiliary energy source of the locomotive is used for driving the locomotive to do the short-distance self-walking.
Description
Technical field
The invention belongs to electric locomotive type of drive, being specifically related to a kind of electric locomotive not having externally fed net powers, pantograph fall the short range electric locomotive after bow power-off from walking manner, being mainly used in electric locomotive losing the short range under externally fed state walks voluntarily.
Background technology
Current electric locomotive be all rely on pantograph to obtain electric energy from external electrical network from walking, then by the conversion of electric energy, drive locomotive to walk by traction electric machine.The primary prerequisite of this type of drive is exactly that the traction electric machine of locomotive must be driven by external power source, if do not have external power source, traction electric machine will lose driving power, cause locomotive not walk.So at present electric locomotive is all rely on exterior power supply plant to provide power to realize from walking for traction electric machine from walking.But in actual applications, also often occur that electric locomotive loses externally fed, but still need the situation of walking; Test as appointment platform position will be arrived in electric locomotive in fabrication shop, and need when electric locomotive runs to certain to overhaul to Maintenance Bases, at this moment in order to ensure locomotive reorganizing and outfit, test, work safety does not allow to set up aerial supply network in manufacturing shop and overhaul shop and powers in service work; In addition, regular link when travelling, because railway power supply electrical network is that segmentation is powered, be provided with insulation strip between every two sections of power supply grids, sometimes locomotive is because sudden stop makes locomotive just in time be parked on insulation strip, and electric locomotive so also will be made cannot to obtain electric energy from power supply grid.In these cases, though electric locomotive has lost the possibility directly being obtained electric energy by electrical network, locomotive has still needed to walk in these regions, to make locomotive can enter in workshop, or disengaging insulation strip, comprise after railcar has a power failure and promptly move to side road from traction.At present, in order to address these problems, usually solve in the following ways:
1, side formula contact system mode is close to
Be used for the locomotive test of fixing, inspection rack position, above this position, erection has and is telescopicly close to side formula contact system, when locomotive will pass in and out this section, contact system extends outward to above locomotive, and this contact system inlet side is connected with supply regular power net outside platform position (retaining insulation isolation section), and powers to being close to side formula contact system, locomotive can obtain supply network and power inside and outside platform position, can normally sail or roll away from this position into.When locomotive is in order in platform position, when needing test, maintenance, be close to side formula contact system power-off, and draw in from trend side, ensure there is no net and electricity above locomotive.Overhaul, tested, need to roll platform position away from, be close to side formula contact system and stretch out and power, locomotive rolls away from by normal mode of operation.
2, tractor truck mode of traction
The method be mainly used in locomotive be in insulation strip or test inspection rack position time, owing to not establishing supply network at insulation strip or test inspection rack position, locomotive to be drawn in by hitch by other tractor truck (other energy motor-cars such as combustion power, storage battery power) or pulls out by the insulation strip that locomotive passes in and out this position or departs from circuit.The method is simple, and do not need in test, inspection rack position configures special equipment, but must be equipped with spcific power car in addition, and each motor-car all needs scheduling and waits for.
3, trailing cable power supply mode
General locomotive is provided with all motor-car battery socket in storehouse, in locomotive test, inspection rack position is other arranges fixing motor-car power supply (according to locomotive principle and motor-car needs, the unit of configurable DC supply or three-phase alternating-current powered), by supply cable and matched plug, power supply is introduced locomotive motor-car socket, control power supply unit, can motor-car be realized.When adopting this kind of mode motor-car, at the regional level, longer supply cable to be introduced, all bring some inconvenience and problem to operation and safety.Because cable length is limited, locomotive movable scope is also restricted.
Above-mentioned several motor-car mode has the utilization of long period all at the scene, also all comes with some shortcomings.Mainly when above-mentioned nothing electricity, motor-car cumbersome; Particularly on-the-spot utilization department, sometimes locomotive to be incorporated into appointed condition simpler and cruder reorganize and outfit field.The operation of aforesaid way is all unrealistic and convenient, and on-the-spot needs a kind of needs carries out larger input and transformation to platform position, and comparatively easy nothing electricity is from the motor-car mode of walking.
