Description of drawings
Fig. 1 is pedal scheme of installation in prior art;
The pedal device three-dimensional structure schematic diagram that Fig. 2 provides for the utility model embodiment;
Fig. 3 is in the rollover states master after pedal device shown in Figure 2 is installed to look schematic diagram;
Fig. 4 is Fig. 3 left view.
The specific embodiment
The pedal device three-dimensional structure schematic diagram that Fig. 2 provides for the utility model embodiment, Fig. 3 are to be in the rollover states master after pedal device shown in Figure 2 is installed to look schematic diagram, and Fig. 4 is Fig. 3 left view.
The utility model embodiment provides a kind of pedal 2 devices, wherein, comprises stay bearing plate 1, pedal 2 and pin 3.Stay bearing plate 1 is used for fixing with railway truck, and described stay bearing plate 1 arranges in pairs, offers open slot 11 on each described stay bearing plate 1, and described open slot 11 has the horizontal segment of connection 111 and vertical section 112.Pedal 2 has pin and steps on section 21 and be arranged on the connecting portion 22 that described pin is stepped on section 21 two ends; Pin 3 is fixed on described pedal 2; Wherein, described pedal 2 is connected with described stay bearing plate 1, and can and move up and down with respect to described stay bearing plate 1 upset; When described pedal 2 is in rollover states, described pin 3 is arranged in described open slot 11.
Stay bearing plate plays a supportive role, and when pedal is in rollover states, locks the effect of pedal position by pin.The pin size should be able to guarantee to snap in open slot.Herein, open slot is arranged to have the shape that is communicated with horizontal segment and vertical section, and when the pedal upset was positioned at vertex, pin should enter into horizontal segment; Then under Action of Gravity Field, pedal moves downward, and pin enters into the bottom of vertical section, and namely the open slot of above-mentioned shape plays anti creep performance, thereby makes pedal keep firm rollover states.
The connection mode that can relatively rotate between stay bearing plate and pedal and can move up and down has multiple, and such as adopting a plurality of Mechanism Combinations, a mechanism is used for realizing separately that upset, another mechanism are used for realizing separately moving up and down.
Preferably, adopt following implementation in the present embodiment: offer connecting bore (scheming not shown) on each described stay bearing plate 1, connecting bore is positioned at the below of described open slot 11; Offer slotted hole 23 on each connecting portion 22, pin 3 is positioned at the below of slotted hole 23; Pedal 2 devices also comprise attaching parts 6, and attaching parts 6 has end cap, connecting rod and tight lock part; End cap is fixed on the end of described connecting rod, and tight lock part and connecting rod are removable fixing; Wherein, connecting rod wears connecting bore and described slotted hole 23, and end cap is stuck in slotted hole 23 outsides, and tight lock part is stuck in the outside of connecting bore; The allowance m that moves up and down of pedal 2 is the diameter d that the length l of slotted hole 23 deducts connecting rod, moves up and down the vertically degree of depth h coupling of section 112 of allowance m and open slot 11.
End cap is stuck on pedal that side away from stay bearing plate, makes between pedal and stay bearing plate to maintain the connection.The size of connecting rod take by connecting rod as example as round bar less than the length of slotted hole, and the diameter that the length of slotted hole deducts connecting rod is pedal and moves up and down allowance.This allowance should with the vertical degree of depth coupling of section of open slot so that open slot can play a supporting role to pin, to reduce the application force of the vertical direction that connecting rod is subject to, guarantee the service life of connecting rod.
Herein, described connecting bore and described slotted hole 23 are unthreaded hole, to reduce difficulty of processing, reduce manufacturing cost.
Further, be provided with outside thread on described connecting rod, described tight lock part is nut.Bolt connects reliable, and easy accessibility.
Particularly, pedal 2 devices comprise that also baffle plate 7, baffle plate 7 are fixed on described stay bearing plate 1, and are positioned at a side of described pedal 2.
During installation, baffle plate arranges baffle plate and can so that pedal does not rock toward car body, guarantee the safety that the user gets on or off the bus over there between car body and pedal.The quantity of baffle plate can be one or two, is understandable that, as long as there is one just can play the effect that the restriction pedal does not rock toward car body over there, whole device is more firm but all arrange one on each stay bearing plate.
Herein, the pin of pedal 2 steps on section 21 and connecting portion 22 is flat board, and each connecting portion 22 is stepped on section's 21 arc transition with pin.
Described pin is stepped on section 21 can be one-body molded with each described connecting portion 22.
The pedal device that technique scheme provides when driving, can overturn pedal, and utilize pin that pedal is limited in upturned position, has improved the safety of driving; When stopping use, pedal is put down, pedal is little apart from the distance of orbital plane, convenient for passenger to get on and off.
The utility model embodiment also provides a kind of railway truck, comprises car body, wherein, also comprises the pedal device that the utility model any embodiment provides; The stay bearing plate of described pedal device and described car body are fixed.
Above-mentioned railway truck has pedal device, when driving, with the pedal upset, does not invade vehicle gauge of the locomotive to guarantee pedal device, thereby guarantees the safety of driving.When using, pedal can be overturn, guarantee to descend most under pedal single order apart from orbital plane less than 500mm, the convenient use.
It should be noted that at last: above each embodiment is not intended to limit only in order to the technical solution of the utility model to be described; Although with reference to aforementioned each embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps some or all of technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the scope of each embodiment technical scheme of the utility model.
