Technical field
The present invention relates to Transit Equipment technical field, specially a kind of protective device of pantograph pan.
Background technique
Referring to Fig. 1, electric locomotive obtains electric energy, tractor-trailer train operation, by electricity from contact net using the pantograph of roof
Bow is mounted on the roof of electric locomotive by insulator, is a kind of mechanical component of radial type.When pantograph rises, slide
Plate is directly contacted with contact line conducting wire, by obtaining current from contact line conducting wire, and it is sent in locomotive by roof bus
Portion is used for locomotive.
In order to reduce cable generation abrasion, usually by hardness, lower graphite is made slide plate, train high-speed cruising when
Time can rapidly deplete graphite slide plate, usually require to replace slide plate to surrounding every two, the replacement cost of slide plate compared with
To be frequent, while electric arc can be all generated with conductive cable contacts and isolated moment in slide plate, the high temperature that arc discharge generates can reduce
The smoothness of graphite aggravates the abrasion of slide plate, constrains the service life of slide plate.
Further, it may break down during rising bow and receipts bow, if slide plate and high-voltage line when breaking down
Between pressure it is too small or hypotelorism when, lasting electric arc can be generated between high-voltage line and slide plate, greatly damage high pressure
Line and slide plate, if even if can not be detached from, or even have the possibility for causing fire, it brings great potential safety hazard.
Further, in order to more scientifically with changing slide plate, need to slide plate abrasion condition be monitored, it is existing by
Pantograph usually using real-time watch device real-time monitoring or personal monitoring, real-time watch device costly, and personal monitoring
It is excessively inefficient.
Summary of the invention
For the deficiency of above-mentioned background technique, the present invention provides a kind of protective devices of pantograph pan, have and avoid
Electric arc injury, the advantage that highly-safe and detection is simple, solve the problems, such as background technique proposition.
The invention provides the following technical scheme: a kind of protective device of pantograph pan, including mounting rack, the mounting rack

The present invention have it is following the utility model has the advantages that
1, two protection boards are resisted high-voltage line when train prepares to receive bow by the protective device of the pantograph pan
Restart receipts bow, since the distance of protection board distance high-voltage electricity is closer, the electric arc of the moment generation of support plate and high-voltage electricity disengaging
It all acts on protection board, avoids arcing on the supporting plate, reduce the abrasion of support plate, that improves support plate uses the longevity
Life, while ensure that the smoothness of support plate surface, and then generate less top in the normal sliding of high-voltage electricity and support plate
It winnows with a dustpan, the electric arc generated when train driving when reducing work further reduces the damage of support plate.
2, the protective device of the pantograph pan breaks down in pantograph and high-voltage line with support plate is closer or presses
When power is too small, protection board is simultaneously resisted high-voltage line by mobile protection board, is squeezed into the gap between high-voltage line and support plate, is made to protect
Backplate is adjacent to high-voltage line, avoids continuous discharge between high-voltage line and support plate, excludes security risk.
3, the elastic force of holddown spring is transmitted on pressure sensor by the protective device of the pantograph pan by hydraulic oil
And the abrasion loss of support plate is measured by the elastic force that pressure sensor detects, and then the residual thickness of real-time detection support plate, one
Aspect can amplify the elongation of holddown spring by hydraulic oil, improve detection accuracy, on the other hand, detect position far from high pressure
Route avoids electromagnetic interference, detects more flexible.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 2-5, a kind of protective device of pantograph pan, including mounting rack 1 are please referred to, the upper end of mounting rack 1 is fixed to be connected
It is connected to slide plate 3, the upper end of slide plate 3 is equipped with support plate 2, and mounting rack 1 and slide plate 3 play the role of support to support plate 2, support
The upper surface both ends of plate 2 slidably connect protection board 4, and the sliding of protection board 4 is adjacent to high-voltage line, when slide plate 3 and high-voltage line are detached from
When, since protection board 4 is closer from high-voltage line, electric arc be will occur between high-voltage line and protection board 4, and the lower end of protection board 4 is fixed
It is connected with fastening frame 5, protection board 4 is limited on the surface of support plate 2 by fastening frame 5, and the lower end of fastening frame 5 is connected with drive block
6, drive block 6 is fixedly connected with air bag 8, and air bag 8 is communicated with baffle-box 7, and baffle-box 7 is communicated with air pump 9, and air pump 9 is to baffle-box 7
With inject gas in air bag 8, air bag 8 extends after being passed through gas and drives drive block 6 mobile, and then drives protection board 4 mobile, protects
Impact force will not be generated to high-voltage line while demonstrate,proving the movement of protection board 4, air bag 8 further function as the effect of buffering, avoid air bag 8
Extend too fast.
Wherein, the opposite one side of protection board 4 is equipped with the cambered surface being adapted to high pressure linear diameter, can not move in bow failure
When, it is inserted into the gap between slide plate 3 and high-voltage line by the inclined-plane of protection board 4, avoids holding between high-voltage line and slide plate 3
Continuous to generate electric arc, the material of protection board 4 is graphite, reduces the fretting wear between protection board 4 and slide plate 3 and will not be to high-voltage line
Generate injury.
Wherein, the inside of drive block 6 is equipped with cylindrical cavity, and detection piston 12 is slidably connected in the cavity of drive block 6,
The top for detecting piston 12 is equipped with compact heap 14, is slidably connected between compact heap 14 and fastening frame 5, and compact heap 14 and slide plate 3 are sliding
