Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.It is to be understood that
It is that detailed description of the invention described herein is merely to illustrate and explains this utility model, is not used to limit
This utility model processed.
A kind of pump truck stair that this utility model provides and the pump truck installing these pump truck stair.
As it is shown in figure 1, according to an aspect of the present utility model, it is provided that a kind of pump truck stair, including building
Ladder main body 2, in order to realize the purpose of this utility model, this pump truck stair also include staristep 3, stair
The bottom of main body 2 offers the first spacing hole 22 and the first hinge hole 27, and stair main body 2 offers
It is positioned at the 4th spacing hole 23 above the first spacing hole 22 and the first hinge hole 27, the first of staristep 3
End is formed with the second spacing hole 32 and the second hinge hole 37, contrary with the first end of above-mentioned staristep 3
Second end is formed with the 3rd spacing hole 33.
Staristep 3 is locked in the end of stair main body 2 rotationally by the first bearing pin 4 and the second bearing pin 5
End, wherein the first bearing pin 4 inserts the first hinge hole 27 and the second hinge hole 37 staristep 3 can be turned
Being connected to the bottom of stair main body 2, the second bearing pin 5 is optionally inserted into the first spacing hole 22 He dynamicly
Second spacing hole 32 or the 3rd spacing hole 33 and the 4th spacing hole 23 with by staristep 3 respectively with exhibition
Out position and stowed position are locked in stair main body 2.
In the pump truck stair that this utility model provides, by the first bearing pin 4 is inserted the first hinge hole 27
With the second hinge hole 37 so that staristep 3 is hinged on the bottom of stair main body 2 rotationally, by inciting somebody to action
Second bearing pin 5 inserts the first spacing hole 22 and the second spacing hole 32 so that staristep 3 is from stair main body
2 extend obliquely downward, and are i.e. positioned at displayed position；Or by the second bearing pin 5 is inserted the 3rd spacing hole
33 and the 4th spacing hole 23 so that staristep 3 tilts upward withdrawal from stair main body 2, is i.e. positioned at receipts
Play position.
Utilize the optional characteristic in operating position of staristep 3 so that staristep 3 can be according to pump truck 1 at
Put on display in delivery position or traveling-position in stair main body 2 or regain in stair main body 2.Such as figure
Shown in 2 to Fig. 3, at delivery position, the wheel of pump truck 1 is supported away from ground 6 by supporting leg, then stair
Section 3 is put on display from stair main body 2, diagonally downward to reduce between the lower surface of this pump truck stair and ground 6
Distance, it is simple to staff pedals pump truck 1；At traveling-position, the pressure wheel of pump truck 1 leans against ground
On 6, staristep 3 tilts upward withdrawal from stair main body 2, with the traveling of this pump truck of anti-interference, it is ensured that
The property passed through of pump truck 1.
Specifically, the bottom of stair main body 2 is arranged with pair of side plates 24 in parallel, this pair of side plates 24 edge
Stair main body 2 extends obliquely downward and is formed cantilever design, and each side plate 24 offers first respectively
Spacing hole 22 and the first hinge hole 27, alternatively, the first spacing hole 22 on each side plate 24 and
The first spacing hole 22 that one hinge hole 27 can be spaced in laying, and this pair of side plates 24 is coaxially laid,
The first hinge hole 27 in this pair of side plates 24 is coaxially laid.Accordingly, above-mentioned the first of staristep 3
End is provided with offers the second spacing hole 32 and articulated slab 34 of the second hinge hole 37, and this articulated slab 34 is inserted
Enter between above-mentioned pair of side plates 24.
So, the space that the first end of staristep 3 rotates it is formed between two side plates 24, it is to avoid
Interfere, additionally, the first end deviation stair main body 2 that two side plates 24 can also limit staristep 3 is moved
Dynamic.
So that the 3rd spacing hole 33 is the most corresponding with the 4th spacing hole 23, alternatively, at stair
Second end of section 3 is vertically connected with connecting plate 35, and the 3rd spacing hole 33 is opened in oneself of this connecting plate 35
By holding.Then it is in stowed position when staristep 3, rotates the staristep regained from the bottom of stair main body 2
Connecting plate 35 on 3 can extend further to stair main body 2, so that the 3rd spacing hole 33 and
Four spacing holes 23 are overlapping, it is simple to the second bearing pin 5 spacing.
In optional embodiment of the present utility model, side plate 24 be substantially in isosceles trapezoid tabular knot
Structure, the short base of this isosceles trapezoid is fixed on the bottom of stair main body 2, the first spacing hole 22 and first
Hinge hole 27 is laid respectively close to the long base of isosceles trapezoid and the angle of waist.Thus the first spacing hole 22
With the both sides that the first hinge hole 27 may be located at stair main body 2, the i.e. first spacing hole 22 and first is hinged
Hole 27 may be located at the both sides of the bottom surface of stair main body 2, thinks that the rotation of staristep 3 provides space,
Prevent the bottom surface interference of staristep 3 and stair main body 2.
Wherein, stair main body 2 also includes installing plate the 28, first pedal 25 and the first cant beam 21, installs
The side of plate 28 is for installation on pump truck 1, and the first cant beam 21 tilts along the opposite side of installing plate 28
Downwardly extending, the first pedal 25 includes multistage and is fixed on spaced reciprocally on the first cant beam 21, stair
Section 3 includes the second cant beam 36 and the second pedal 31 being arranged on this second cant beam 36, the first pedal
25 are parallel to the second pedal 31.Wherein installing plate 28 removably can be installed by securing members such as bolts
On pump truck 1, it is also possible to being fixed on pump truck 1 by welding manner, this is not limited by this utility model
System.
Above-mentioned second pedal 31 includes that at least one-level, concrete pedal progression can be arranged according to actual needs.
Further, the first cant beam 21 is additionally provided with handrail 26, for the work scrunching this pump truck stair
Grip as personnel, prevent from falling down.
In optional embodiment of the present utility model, in the stowed position of staristep 3, staristep 3 is led to
Crossing the first bearing pin 4 to rotate to the lower surface fitting to the first cant beam 21, the 4th spacing hole 23 interval is offered
Above the first cant beam 21 bottom, so that the 3rd spacing hole 33 in staristep 3 is spacing with the 4th
Hole 23 is corresponding, so, it is simple to the staristep 3 packed up is defined, and simple in construction.
To sum up, inconvenience when the pump truck stair that this utility model provides pump the materials such as slow setting soil for pump truck 1
Pedal the phenomenon of upper pump truck 1 in staff, by installing additional in stair main body 2, there are displayed position and receipts
Play the staristep 3 of position so that this pump truck stair can adapt to the various states of pump truck 1, such as, pump
State and transport condition etc., in order to staff's ascending stair is got on the bus.
Optional embodiment of the present utility model is described in detail above in association with accompanying drawing, but, this practicality is new
Type is not limited to the detail in above-mentioned embodiment, in technology concept of the present utility model,
The technical solution of the utility model can be carried out multiple simple variant, these simple variant belong to this reality
With novel protection domain.
It is further to note that each the concrete technology described in above-mentioned detailed description of the invention is special
Levy, in the case of reconcilable, can be combined by any suitable means, in order to avoid need not
The repetition wanted, various possible compound modes are illustrated by this utility model the most separately.
Additionally, combination in any can also be carried out between various different embodiment of the present utility model, only
Wanting it without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
