Description
Technical field
The utility model relates to a kind of passenger train member, relates in particular to a kind of passenger train telescopic pedal.
Background technology
Station platform previously, the overwhelming majority are low platforms.After needing the train attendant to open car door after car arrives at a station, open the railway platform turnover panel, the passenger gets off to platform along step.Along with the speed-raising of railway, present station platform has much become " high platform ", and promptly the platform plane is basic contour with ground, compartment, just only needs driving like this behind the train arrival, the railway platform door turnover panel of the car door that need not to overturn, but passenger's more convenient and quicker get on and off.
But because the needs of train operating safety, leave the safety distance of wide about 0.2m between station platform and the rail vehicle, when the passenger gets on and off, this wide about 0.2m, the degree of depth surpasses " ditch " of 1m, can make the handicapped passenger of minority feel inconvenience, and directly influence is the dwell time that possible prolong train, careless slightly, the accident that personal limbs injure also may take place.
For eliminating safe hidden trouble, it is more convenient quick that the passenger is got on and off, existing way is that the train attendant places a cover plate after opening car door, to connect compartment and platform, also then be provided with the telescopic pedal of dynamic driving, behind the car door opening just like " Harmony " motor train unit, pedal stretches out, after the pedal withdrawal, closing of the door gets on and off to make things convenient for the passenger.
Summary of the invention
The purpose of this utility model is: the situation at the exhausted most passenger car that runs on china railway at present (still not having " Harmony " such telescopic pedal), the railway platform door turnover panel that provides a kind of and be applicable to passenger train, is installed on passenger door below is interior, safe and reliable, make the get on and off passenger train telescopic pedal of more convenient and quicker of passenger.
The purpose of this utility model realizes by following scheme: be made of by hollow tubular bonded assembly spanner turnover panel and turnover panel one side end, it is characterized in that: spanner is for can reverse spanner, and be provided with gear, rack gear, comprise driving wheel, flower wheel, sectional wheel, idle wheel and tooth bar, driving wheel and flower wheel engagement, flower wheel and sectional wheel are placed on the primary shaft jointly, sectional wheel and the idle wheel engagement that is placed on second, idle wheel and tooth bar engagement; The hollow belly of turnover panel is provided with telescopic pedal, and tooth bar is fixed in the telescopic pedal bottom surface; Be provided with tommy bar in the hollow tubular, driving wheel is placed in the tommy bar bottom, and the tommy bar top connects can reverse spanner.
The utility model turnover panel panel is provided with the locking interlock system, and the locking interlock system is made of interlock pin, retracing spring and framework, and frame fixation reaches telescopic pedal and is equipped with lockhole corresponding to the interlock pin bottom in turnover panel on the turnover panel panel.
Driving wheel described in the utility model, flower wheel are sectional wheel.
The spanner that reverses described in the utility model is fixed in hollow tubular top by pivot pin, can reverse spanner upper end and form the U-shaped bayonet socket laterally, fixes a dead bolt by the tommy bar seat, and when the U-shaped bayonet socket that reverses spanner was in level, dead bolt snapped in the U-shaped bayonet socket.
The utility model has been simplified pedal structure, is convenient to train attendant's operation, and durable in use, convenient for maintaining.After the railway platform door turnover panel of existing passenger car reequiped, do not influence this turnover panel passenger when low platform and get on and off.And when running into high platform, this telescopic pedal flexible freely, safety control when satisfying the passenger and getting on and off, effectively shorten passenger's required time that gets on and off, satisfy the requirement of " safe, quick, comfortable " of railway transportation better, be applicable to passenger train, neither influence traffic safety, can make passenger's more convenient and quicker that gets on and off again, guarantee personal safety.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
The utility model can reverse spanner 2 by turnover panel 1 and turnover panel 1 one side ends by hollow tubular 3 top bonded assemblys and constitute.Newly-increased gear, rack gear, comprise driving wheel 4, flower wheel 5, sectional wheel 6, idle wheel 7 and tooth bar 8, driving wheel 4 and flower wheel 5 engagements, flower wheel 5 is placed on the primary shaft 9 jointly with sectional wheel 6, sectional wheel 6 and idle wheel 7 engagements that are placed on second 10, idle wheel 7 and tooth bar 8 engagements.The hollow belly of turnover panel 1 is provided with telescopic pedal 11, and tooth bar 8 is fixed in telescopic pedal 11 bottom surfaces.Be provided with tommy bar 12 in the hollow tubular 3, driving wheel 4 is placed in tommy bar 12 bottoms, and tommy bar 12 tops connect can reverse spanner 2.Turnover panel 1 panel is provided with the locking interlock system, and the locking interlock system is made of interlock pin 13, retracing spring 14 and framework 15, and framework 15 is fixed in the turnover panel 1, reaches telescopic pedal 11 on turnover panel 1 panel and is equipped with lockhole 16 corresponding to interlock pin 13 bottoms.
Can reverse spanner 2 and be fixed in hollow tubular 3 tops by pivot pin 19, can reverse spanner 2 upper ends and form the U-shaped bayonet socket laterally, fix a dead bolt 18 by tommy bar seat 17, when the U-shaped bayonet socket that reverses spanner 2 is in level, dead bolt 18 snaps in the U-shaped bayonet socket, lift and reverse spanner 2 and make the U-shaped bayonet socket break away from dead bolt, thus by reverse tommy bar 12 and gear, rack gear realizes the flexible of telescopic pedal 11.
Working process of the present utility model and principle are as follows: platform stopped by train and when running state, not with car door opening, then telescopic pedal is in locking states as if the train attendant, and telescopic pedal can't stretch out.Behind the car door opening, then can reverse spanner, telescopic pedal is stretched out, so that the passenger gets on and off.At this moment, the locking interlock system makes the telescopic pedal can not play, to guarantee passenger's safety that gets on and off.Before train started, the train attendant must the locking car door, but telescopic pedal is not when withdrawing, and car door can't locking.
