Pedal cover plate 105 surfaces of said pedal can process anti-skidding lines.
Said urgency is stopped safety protection switch 111 and is the one stroke switch; With the urgency of a last preferred version stop safety protection switch different the time, it adopts " normally closed " as the normal signal of system, when meeting obstacle except said device with pedal; Said urgency is stopped safety protection switch can become " holding " by " closing "; Force driving host to quit work, meanwhile, when said urgency is stopped safety protection switch self damage; " normally closed " signal will lose efficacy, so this mounting means has " suddenly stopping protection " and " self damages detection " dual-use function.
A kind of device with pedal; It comprises unit-cast unit pedal 34, lower cover, the anxious fender guard 103 that stops; Said unit-cast unit pedal 34 is for being cast into said pedal cover plate 105, footrest frame 106, pedal adapter shaft 102 unified whole; Consider that unit-cast unit proposes higher requirement to said pedal stability, said unit-cast unit pedal 34 can water and cast out reinforced rib, and said pedal adapter shaft 102 is except circular shaft cooperates; The cross section 35 that said pedal adapter shaft cooperates with the rail vehicle rotating shaft can be square, and said pedal adapter shaft 102 is axially also fixing through jam nut 38; Said urgency is stopped fender guard 102 and is comprised that urgency is stopped protection triggering part 109, urgency stops protecting safety switch 111, bearing 36, leaf spring 33; Said urgency is stopped protection triggering part 109 and is integral molded plastic spare; Possess anxious protection triggering and the guiding push rod dual-use function of stopping; It is one " two-way " effective travel switch that said urgency is stopped safety protection switch 111, one side stop protection when triggering that part 109 is any to run into obstacle when said urgency, all can trigger said urgency and stop safety protection switch 111; Said bearing 36 can make said urgency stop protecting the motion that triggers part more smooth and easy; Said lower cover stops protection triggering part with said urgency and is enclosed in the guide groove.
Said urgency is stopped fender guard 103 except that such scheme; Can comprise that also urgency is stopped protection triggering part 109, urgency stops protecting safety switch 111, leaf spring 33, bearing 36, tumbler 37; Said tumbler 37 is installed on the said unit-cast unit pedal 34, can one torsion spring be installed on it around a spot wobble; Said urgency is stopped protection when triggering part 109 and running into obstacle, can order about said tumbler 37 swings and go to trigger said urgency and stop safety protection switch 111.
Present embodiment is a kind of device with pedal that is used for passageway lift, simultaneously also can be applied in following occasion: need bear certain load and take exercises, and in motion process, possibly run into the device with pedal of obstacle.Said device with pedal comprises pedal 101, pedal adapter shaft 102, anxious fender guard 103, lower cover, pedal adapter shaft fulcrum carrying structure 104, the cable cutting ferrule of stopping.Pedal 101 and the splicing construction of pedal adapter shaft or the design of unit-cast unit forming technology in the present embodiment; Main from satisfying under the rated load burden; Alleviate the weight of device with pedal as far as possible; Simultaneously, especially to note stress concentration that in shafting structure shaft shoulder transition position stress concentration or technique for welding cause very big weakening effect to the device with pedal safety performance.Said urgency is stopped the thinking of fender guard 103 when in operational process, meeting with obstacle with said device with pedal; Can touch said urgency and stop protection triggering part 109; And then trigger the anxious safety protection switch 111 that stops and work; Force driving host to quit work, protection passenger's safety, structure design wherein stops protecting the smoothness that triggers part 109 motions and suddenly stops 2 considerations of safety protection switch 111 working stabilitys based on anxious.
Said pedal adapter shaft fulcrum carrying structure 104 is except bearing this function of the suffered part load of pedal; Another function is exactly through said pedal adapter shaft fulcrum carrying structure 104; Think the control system output load-carrying signal of passageway lift, the safety factor that raising equipment uses.When pedal in running order; When promptly transferring to level attitude, have only when on the device with pedal during bearing load, the handrail switch of control vehicle track running just is in " effectively " state; When on the device with pedal during no-load; Handrail switch " inefficacy ", the handrail switch is touched when avoiding not standing on the pedal as yet because of the people, causes vehicle track running generation casualty accident.Its mode of operation is described below: when said pedal is opened to control position; Said pedal adapter shaft 102 tail ends promote said screw putter 17 and remove to touch said pedal earlier and put and trigger travel switch 18; The pedal opening action finishes, and at this moment, said pedal adapter shaft 102 tail ends contact with said vertical rod sleeve 15 just; Because the existence of said first compression spring 16 relies on the weight of pedal self can't promote said vertical rod sleeve 15 motions; When on the pedal passenger being arranged; Load on the pedal is enough to promote said vertical rod sleeve 15 and moves; Tail end up to said pedal adapter shaft 12 contacts with said carrying support vertical rod 14; Move on screw putter described in this process 17 continues and trigger said load-carrying micro-switch 19, send the load-carrying signal to control system; When the passenger left pedal, said first compression spring 16 let said vertical rod sleeve 15 reset.
And another scheme lets said pedal adapter shaft 102 directly remove to touch said LOAD CELLS 21, sends weight signal by LOAD CELLS, said LOAD CELLS 21 also can realize the overloading function of early warning.
