Description
Technical field
The invention belongs to haulage vehicles, and in particular to a kind of miniaturization pantograph, rail vehicle and its examination and repair system, especially
Suitable for subway and light rail vehicle.
Background technique
With making constant progress for technology of track traffic, on the main track of subway and light rail, cable of powering is by rigid and soft
Property suspension standard and deposit, gradually development is completely rigid suspended power supply cable.In this way, to the dynamic of subway and light rail pantograph by
Stream stability and structural strength made higher requirement.
In actual use, pantograph need to meet main track and two kinds of car inspection and repair section different suspension standard power supply cables.According to
Standard, the power supply network line height to the top of rail of main track are generally 4040mm, and pantograph lifting heights are about 210mm when operation；Vehicle
Maintenance library power supply network line height to the top of rail is usually no more than the repair and maintenance that 5700mm(is mainly vehicle top air conditioner unit and pantograph
Reserved space), it is desirable that the working depth of pantograph is about 2000mm.
The pantograph of existing subway and light rail is all to continue to use main line and large scale that high-speed rail electric locomotive technology communicates is big
It is left to rise 210mm in the case where meeting rigid suspended power supply cable and being flowed for structural shape, the pantographs of this coarse scale structures
Right height, which is contacted with power supply cable, to be flowed.Although can guarantee to run, since pantograph size is big, subway and light rail
Cable design height of powering is small compared with main line and high-speed rail electric locomotive, large scale pantograph collocation lower height power supply cable occurs
The problem of, it is directly resulting in the result is that the pantograph frame structure of subway and light rail using stress it is very big, pantograph just as
One people not trailed, bow-backed stress so that pantograph bow net dynamic by when stream stability is insufficient and vehicle crosses bend by
Pantograph shaking volume is big.
The rising bow elevation angle: technical term refers to angle when rising bow state between upper armed lever and lower arm rod.
Summary of the invention
In view of the above-mentioned problems, the present invention is intended to provide it is a kind of using stress it is small, have well by fluidity can miniaturization by
Pantograph is particularly suitable for subway and light rail vehicle.
The technical solution that the present invention solves the problems, such as is: a kind of miniaturization pantograph, including chassis, be mounted on chassis under
Armed lever, the upper armed lever hinged with lower arm rod upper end, pull rod, bow, the upper armed lever include the first armed lever section and are set to first
Second armed lever section of armed lever section lower end, there are angle, the first armed lever sections between the first armed lever section and the second armed lever section
Upper end is hinged with bow, and the second armed lever section lower end and pull rod upper end are hinged, and pull rod lower end and chassis are hinged, the first armed lever section
Length A is 955≤A≤1850 millimeter, and the second armed lever segment length B is 157≤B≤282 millimeter；The lower arm pole length C is 800
≤ C≤1447 millimeter；
Rising bow elevation angle theta range between lower arm rod and the first armed lever section is 14 °≤θ≤69 °.
Above scheme changes upper armed lever, lower arm rod, the several sizes in the rising bow elevation angle in prior art basis, while can press
The size of scale smaller pantograph other structures reduces the framework size of pantograph, preferably reduces making for pantograph
With stress and pantograph with the shaking volume of vehicle, pantograph structure is improved and by stream stability.
Preferably, the rising bow elevation angle is 14 °≤θ≤20 °.
It is furthermore preferred that the first armed lever segment length is 1302 millimeters, the second armed lever segment length is 223.5 millimeters, lower arm
Pole length is 1020 millimeters；
The rising bow elevation angle is 14 °.
Further, the first armed lever section is from top to bottom gradually by thin thicker variable section structure.This design subtracts
The light total quality of pantograph, normalized wave function are small.
It further, further include the monosaccate bow-lifting device being installed vertically on chassis, the balance below upper armed lever
Bar, the balancing pole lower end and lower arm rod upper end are hinged, and the shaft of balancing pole upper end and bow is hinged.
Monosaccate bow-lifting device and balancing pole are all the structures of the prior art, installation connection relationship also with the prior art
It is identical.
Correspondingly, the present invention also provides a kind of rail vehicle, including car body, car body top be equipped with above-mentioned miniaturization by
Pantograph.
The present invention also provides a kind of pantograph examination and repair systems to match with above-mentioned pantograph, including are located at car inspection and repair library
Interior power supply network line segment, further includes above-mentioned rail vehicle, and the rail vehicle is being located at the power supply network line segment in car inspection and repair library just
Lower section, the terrain clearance X of the power supply network line segment in car inspection and repair library are 4800≤X < 5700 millimeter.
Preferably, the terrain clearance of the power supply network line segment in car inspection and repair library is 4800≤X≤5000 millimeter.
It is furthermore preferred that the terrain clearance of the power supply network line segment in car inspection and repair library is 5000 millimeters.
Due to the size reduction of pantograph, the height of the power supply network line segment in car inspection and repair library also will be reduced accordingly,
The case where to avoid power supply cable can not be contacted after rising bow.
According to previous project experiences, subway train air conditioning unit opens desired space within 4600mm, so overhauls
Personnel stand and excessive across the reserved space of cable, therefore cable of powering can reduce, while can guarantee the maintenance of roof again
Operation is 5000mm to the cable height after the reduction of related metro company confirmation.The reduction of power supply cable can incite somebody to action accordingly
Pantograph working depth is reduced to 1300mm or so by 2000mm.
Remarkable result of the invention is:
1. changing pantograph in the height gauge of vertical direction by changing upper armed lever, lower arm rod, the several sizes in the rising bow elevation angle
It is very little, so that the use stress state of traditional large scale pantograph is changed, so that pantograph is reduced using stress, and excessively curved
The shaking volume of pantograph is reduced when road, improves bow net Dynamic Coupling performance, can be good by fluidity.
2. the size of pantograph other structures is reduced in proportion, so that pantograph more compact structure, reduces pantograph
Front face area when operation, reduces windage, reduces roof installation space.
