Below in conjunction with attached drawing, invention is further described in detail, but not as a limitation of the invention.
Embodiment 1：
In conjunction with Fig. 1-Fig. 7, a kind of bearing axis drawing boarding ladder stand is present embodiments provided, from figure 1 it appears that including external slideway
1, middle pumping ladder 2 and interior pumping ladder, the interior pumping ladder are equipped with ladder 5 after the terraced front ladder 4 of interior pumping and interior pumping ladder.
The interior pumping ladder, middle pumping ladder 2 and external slideway 1 are sequentially socketed.The interior tablet for taking out ladder, middle pumping ladder 2 and external slideway 1 is band
There is the steel plate of slotted hole to make, as can be seen from Figure 3.
From figure 3, it can be seen that the both sides of the external slideway 1 are equipped with slot slideway 11, the lower end base of the external slideway 1
Outside is equipped with external slideway idler wheel 8, the side wall of external slideway 1 is equipped with limit hole, close to described 2 latter linked one end of extraction of middle pumping ladder
For lower end；
The middle both sides for taking out ladder 2 are equipped with slot slideway 11, and the middle both ends for taking out ladder 2 are respectively equipped with middle pumping 10 He of terraced front wheel
The terraced rear roller 6 of middle pumping, upper end is the terraced front wheel 10 of middle pumping, lower end is the terraced rear roller 6 of middle pumping, and the middle pumping ladder front wheel 10 is located at
On the slot slideway 11 of the external slideway 1, roll and connect with slot slideway 11, the middle side wall for taking out terraced 2 upper ends be equipped with it is described
Position when the matched bullet pin 9 of limit hole, 2 extraction terraced for pumping in limitation, structure and the prior art construction phase of bullet pin 9
Together, it is not specifically limited here；
The interior upper end for taking out ladder is equipped with the terraced idler wheel 7 of interior pumping, and the interior terraced idler wheel 7 of pumping is located at the middle slot slideway for taking out ladder 2
Connection is rolled on 11, with the middle slot slideway 11 for taking out ladder 2, interior pumping ladder limit pin shaft 3 is equipped on the inside of the interior upper end for taking out ladder, for limiting
Position when ladder extraction is taken out in making, ladder 5 is hinged after interior pumping ladder front ladder 4 and interior pumping ladder, and ladder 5 is square counterclockwise along hinge after interior pumping ladder
Folded to the terraced front ladder 4 of interior pumping, it is described it is interior take out terraced front ladder 4 with it is interior take out positions that ladder 5 after ladder is connect equipped with holder 13, be used to support
Interior pumping ladder lands.Limit pivot pin in the present invention is identical as structure in the prior art, is not specifically limited here.
The middle ladder 2 of taking out is equipped with warning sign below the interior end for taking out terraced one end.This is one of the present invention and sets
Main points are counted, when interior pumping ladder is extracted out, warning sign is overturn earthward, and when interior pumping ladder is back into external slideway 1, warning sign is flipped back to
See towards the rear of vehicle so that rear side carrys out vehicle original position.
The lower end of the external slideway 1 is equipped with gentle slope, and the gentle slope of external slideway 1 and the angle of middle pumping terraced 2 exist after middle 2 extraction of pumping ladder
Between 5-15 degree.The middle lower end for taking out ladder 2 is equipped with the second gentle slope 12, it is interior take out after ladder extraction middle the second gentle slope 12 for taking out ladder 2 with
The interior angle for taking out ladder is between 5-15 degree.Second gentle slope 12 is as can be seen from Figure 4 come, and anti-skid chequer is designed on gentle slope,
And the setting of this angle is not only conveniently got on the bus but also transition of getting on the bus is steady.
Preferably, bearing is installed in the idler wheel.It is assembled with bearing in whole idler wheels in the present invention.External slideway rolls
Wheel 8 and middle pumping ladder front wheel 10 keep terraced 2 pulls of middle pumping more smoothly, will be in idler wheel because 8 load-bearing of external slideway idler wheel is larger
Bearing is installed, frictional force is reduced, ensure that idler wheel rotation is smooth.The terraced rear roller 6 of middle pumping and interior pumping ladder idler wheel 7 ensure that interior
It is more smoothly to take out terraced pull.Bearing is installed in interior pumping ladder idler wheel 7, convenient for the terraced more smoothly pull of interior pumping.
Embodiment 2：
The present embodiment is Application Example, as illustrated in figs. 5-7, first that middle pumping ladder 2 and interior pumping ladder is same when use needs to get on the bus
When pull out out of external slideway 1（As shown in Figure 5）, forget about it at limit hole, bullet pin 9 is locked, and middle pumping ladder 2 positions；Interior pumping ladder is drawn again
Go out to spacing place, axis pin limit prevents vibration, and after interior pumpings ladder terraced 5 are opened（As shown in Figure 6 and Figure 7）, ground is fallen within, is put
Steadily；
When needing to withdraw cat ladder, ladder 5 after interior pumping ladder is first folded into the upper surface of interior pumping ladder front ladder 4, it simultaneously will be interior after coincidence
Ladder 5 lifts after taking out terraced front ladder 4 and interior pumping ladder, is pushed away into middle pumping ladder 2, and axis pin retracts original position, since interior pumping ladder is equipped with interior pumping ladder
Then idler wheel 7 lifts middle pumping ladder 2, is pushed away into external slideway 1 again so much smoother can be pushed into interior pumping ladder in middle pumping ladder 2,
Bullet pin 9 unclamps, since middle pumping ladder 2 is equipped with the terraced front wheel 10 of middle pumping, so being easy for middle pumping ladder 2 being back into external slideway
In 1.
Embodiment 3：

Cat ladder realizes pull using the method in embodiment 2.It installs after above-mentioned bearing axis draws boarding ladder stand and is filled convenient for carried Commercial Vehicle
Che Shi, it is convenient and reliable.Boarding ladder stand is easy to operate, reduces labor intensity, increases using space, need not be to existing vehicle
Reequip and just can be used, and cat ladder in the prior art be required for reequiping original vehicle can realize it is flexible.
Bearing axis draws boarding ladder stand to be divided into boarding ladder stand external slideway 1, boarding ladder stand and takes out pumping ladder three in terraced 2, boarding ladder stand
It is most of.Pumping ladder is divided into the terraced front ladder 4 of pumping in boarding ladder stand and boarding ladder stand terraced 5 after pumping ladder in boarding ladder stand.External slideway 1 is in
Ladder 2 is taken out to limit by bullet pin 9.Middle pumping ladder 2 is limited with interior pumping ladder by limit shaft.External slideway idler wheel 8 and middle pumping ladder front wheel 10
It ensure that smooth reliable when terraced 2 pull of middle pumping, bearing be installed in external slideway idler wheel 8, reduces frictional force, ensure that idler wheel
Reliability.The terraced idler wheel of the terraced rear roller 6 of middle pumping and interior pumpings 7 ensure that smooth reliable when the terraced pull of interior pumpings, and interior pumpings ladder idler wheel 7 is interior to be installed
There is bearing, reduce power, ensure that the reliability of idler wheel.It is connected through the hinge between the terraced front ladder 4 of interior pumping and rear ladder, realizes pumping ladder
Turn over function.
Several preferred embodiments of the present invention have shown and described in above description, but as previously described, it should be understood that the present invention
Be not limited to form disclosed herein, be not to be taken as excluding other embodiments, and can be used for various other combinations,
Modification and environment, and the above teachings or related fields of technology or knowledge can be passed through in the scope of the invention is set forth herein
It is modified.And changes and modifications made by those skilled in the art do not depart from the spirit and scope of the present invention, then it all should be in this hair
In the protection domain of bright appended claims.
