Abstract
The utility model discloses a dual-purpose trolley on the ground and an iron rail for a locomotive low voltage direct current power lead car, which is characterized by comprising a support plate, a push rod fixed on the support plate and a detachable connection device used for being connected with a power locomotive. A power converter is arranged on the support plate, and a ground wheel and at least two iron rail wheels are in shaft connected with the bottom of the support plate. The dual-purpose trolley on the ground and the iron rail for the locomotive low voltage direct current power lead car has the advantages that due to the fact that the power converter is placed on the dual-purpose trolley, when the trolley bears the power converter to move on the ground, the ground wheel at the bottom of the support plate rolls on the ground, the iron rail wheels are suspended, and the trolley can be pushed manually. When the lead car is operated, the connection device is connected with a power locomotive body, the iron rail wheels are contacted with a steel rail, and the ground wheel is suspended. When the power locomotive lead car moves, the trolley is pushed or pulled, the iron rail wheels roll on the steel rail, and the trolley synchronously moves along with the locomotive, relative fixing and synchronous movement of the power locomotive and 600V power cables output by the power converter in the car leading process are achieved, and manual carrying of the power converter is replaced.
Description
Technical field
The utility model relates to a kind of car that draws of electric locomotive, relates in particular to a kind of locomotive low-voltage dc power supply and draws car ground rail Two purpose carrier.
Background technology
Electric locomotive falls after bow disengages network source in pantograph, need to use ground power supply with electric locomotive traction in the maintenance storehouse, and the traction electric locomotive moves in the maintenance storehouse, perhaps from the maintenance storehouse with electric locomotive traction outside the maintenance storehouse.
Because it is external direct current 600V that the original design power supply of HXD3 type electric locomotive draws car, but the voltage that present existing power supply draws car is low-voltage direct 60V, and this can not accomplish the task of drawing HXD3 electric locomotive warehouse-in.And if dispose the mains connection set of an output direct current 600V in the storehouse in addition in maintenance, its equipment investment is bigger, and because the voltage of direct current 600V is higher; It is longer to draw car miles of relative movement; The feed cable of direct current 600V mops floor and uses inconvenience, also has the hidden danger of person electric shock injury, and uses the supply convertor of special use that low voltage DC 60V voltage transformation is DC600V voltage; Mop floor though solved the DC600V feed cable, need a dead lift.
Summary of the invention
The utility model technical matters to be solved provides a kind of simple and easy to do and can draw in the car process locomotive low-voltage dc power supply that replaces a dead lift supply convertor in low pressure and draw car ground rail Two purpose carrier.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of locomotive low-voltage dc power supply draws car ground rail Two purpose carrier; Comprise supporting plate and be fixed on push rod on the described supporting plate, be used for and the separable connecting device of electric locomotive bonded assembly; Supply convertor is placed on the described supporting plate, and the bottom of described supporting plate is connected to ground wheel and at least two rail wheels.
Described connecting device is the connection structure of tow chain, hauling rope, hook, permanent magnet or other easy disassembly of captiveing joint with described supporting plate.
Compared with prior art, the utility model has the advantages that because supply convertor is placed on this Two purpose carrier, when dolly carrying supply convertor moves on ground, the ground wheel of dolly supporting plate bottom, in ground surface, rail wheel is unsettled, can artificially carry out dolly; When drawing the car operation, connecting device is connected with the electric locomotive car body, and rail wheel contacts with rail; The ground wheel is unsettled; Electric locomotive promotes when drawing car and moving or the pulling dolly, and rail wheel rolls on rail, with the same moved further of locomotive; Be implemented in the 600V feed cable relative fixed and the same moved further of drawing electric locomotive and supply convertor output in the car process, replace a dead lift supply convertor; And Two purpose carrier is connected with electric locomotive through separable connecting device, can realize the same moved further of dolly and locomotive, can realize separating of dolly and locomotive again.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in the figure; A kind of locomotive low-voltage dc power supply draws car ground rail Two purpose carrier; Travelling car comprises supporting plate 1 and is fixed on push rod 2, the tow chain 3 on the supporting plate 1; The bottom of supporting plate 1 is connected with 11 and two rail wheels 12 of ground wheel, and the end of tow chain 3 is provided with hook 31, and supply convertor 4 is placed on the supporting plate 1.
In the foregoing description, tow chain 3 can use the connection structure of hauling rope, hook, permanent magnet or other easy disassembly to substitute.
Claims (2)
1. a locomotive low-voltage dc power supply draws car ground rail Two purpose carrier; It is characterized in that comprising supporting plate and be fixed on push rod on the described supporting plate, be used for and the separable connecting device of electric locomotive bonded assembly; Supply convertor is placed on the described supporting plate, and the bottom of described supporting plate is connected with ground wheel and at least two rail wheels.
2. a kind of locomotive low-voltage dc power supply as claimed in claim 1 draws car ground rail Two purpose carrier, it is characterized in that tow chain, hauling rope, hook or the permanent magnet of described connecting device for captiveing joint with described supporting plate.
