Description
Technical field
The present invention relates to guideway vehicle retractable foot pedal, particularly a kind of board turning pedal coordinated type retractable foot pedal, belongs to steel structure of car body design field.
Background technology
Domestic railway folding door pedal is three grades of step dead pedal structures, meets domestic platform height demand, but can not meet the situation of the low platform of foreign railway.At present domestic for quite general with the guideway vehicle outlet in underdeveloped countries area in development, in development and underdeveloped countries area basic condition is poor, vehicle gauge is less than normal, low platform situation is more, for example in our certain external project, platform is high only has 200mm, and the interior floor of car is up to arriving 1355mm.If adopt dead pedal structure pedal, subordinate step is excessive apart from platform floor height, affects passenger to get on or off the bus; If directly increase fixed pedestal exponent number, although met the requirement of getting on or off the bus, may cause subordinate pedal to exceed vehicle gauge, affect vehicle driving safety.
For addressing this problem, contriver attempts increasing one-level Active foot plate, if applicant is in the patent of invention " retractable foot pedal for passenger train " of application in 2010.Active foot plate can move down and stretch out in the time that passenger gets on or off the bus, and carries out altimetric compensation, when vehicle operating, can pack up.Can realize this cover action of pedal by increasing ecp module, but this will increase manufacturing cost greatly.
When passenger gets on or off the bus, turnover panel rotates and opens, when vehicle operating, turnover panel rotates and closes, if the action of the action of turnover panel and pedal can be connected by mechanical mode, that just can reduce manufacturing cost greatly, so contriver has designed guideway vehicle board turning pedal coordinated type retractable foot pedal of the present invention.
Summary of the invention
Technical matters to be solved by this invention is, overcomes the above-mentioned shortcoming of prior art, and a kind of guideway vehicle board turning pedal coordinated type retractable foot pedal is provided.
In order to solve above technical matters, guideway vehicle board turning pedal coordinated type retractable foot pedal provided by the invention, comprise fixed pedestal assembly, described fixed pedestal assembly has coaming plate, be fixed on the fixed pedestal in coaming plate, it is characterized in that: described coaming plate below is fixed with by two blocks of side plates and a framework that base plate forms, on described two blocks of side plates by bearing be provided with across pedal shaft, pedal shaft two ends are fixed with respectively pedal pivoted arm, pedal pivoted arm end is hinged with pedal bogie side frame, between pedal bogie side frame across the Active foot plate of the level that is fixed with, on described side plate, be fixed with the back-up block of offering chute, pedal bogie side frame in described chute and slidably, described pedal shaft is fixed with rocking arm, and described rocking arm end is hinged with pull bar, and described pull bar upper end is hinged with the turnover panel pivoted arm fixing with turnover panel rotating shaft.
In order to address the above problem, the present invention also has following further feature:
1, described base plate offers and is applicable to the rectangular opening that Active foot plate enters.
2, when turnover panel is during in closed condition, in Active foot plate income framework; When turnover panel is during in open mode, Active foot plate stretches out in framework.
3, described back-up block has upper bearing surface, and in the time that turnover panel opens to maximum position, the lower end of pedal pivoted arm is supported by described bearing surface.
4, the side plate of described framework is fixed on coaming plate below by bolt or rivet.
5, described pull bar has segmentation adjusting screw structure.
With on the basis of pedal, increase an Active foot plate mechanism at pedal end opening at folding door, in turnover panel rotating shaft, increase pivoted arm, and by pull bar, turnover panel rotating shaft and Active foot plate mechanism are coupled together.In the time that turnover panel rotates, pivoted arm drives pull bar to move, and the rotation that pull bar drives the rotating shaft of Active foot plate mechanism, realizes moving down of pedal by the rotation of pedal shaft and stretch out and playback.
In the time that passenger gets on or off the bus, turnover panel rotates to dig and drives subordinate pedal to move down to stretch out, met the requirement that low platform passenger gets on or off the bus; When vehicle operating, turnover panel rotates to close to drive on subordinate pedal and devolves position, the requirement of vehicle gauge while meeting vehicle operating.
Use function except meeting, pull bar adopts segmentation adjusting screw structure, moves down overhang by adjusting pull bar adjustable in length pedal, effectively reduces assembling difficulty.Adopt seamless bearing in pedal gear rotating shaft place, effectively prevent sand and dust intrusion, ensured the validity of the running of whole mechanism under harsh environment simultaneously.
The mechanical system that adopts this structure pedal realizes turnover panel and Active foot plate interlock, has simplified train attendant's associative operation, effectively reduces productive costs, and while production, most of parts can use the parts of former folding door pedal simultaneously, have reduced technique manufacture difficulty.
