First, top Folding stretcher
Superstructure is only made up of a secondary military Folding stretcher.Therefore, superstructure is not taken and is specifically designed, it is contemplated that directly
Using existing military stretcher, central structure is set to be adapted with it.In the selection of military stretcher, the side using four fold is determined
Formula, advantageously reduces the volume after folding, is convenient for carrying.In the material of stretcher, we select the stretcher structure of aluminium alloy, can
Effectively mitigate weight, meet lightweight requirement in this problem, and have with reliable bearing capacity.
Folding stretcher is made up of middle two parts and side two parts.Middle two parts are used as main body force part, both sides
Part carry support frame, used when being kept flat available for stretcher, meanwhile, this support frame can be used for and middle part floor truck structure
It is connected.On folding mode, using twice to volume occupancy by the way of interior folding, can be effectively reduced.The connection of burst
Mode, not only ensure that effective realization of folder function, also ensure that stability of the stretcher in load capacity.
Between the skeleton of Folding stretcher, connected by the way of enveloped, be not only used to carry top weight in expansion
Amount, after folding, can also make the framework shrinkage on both sides reduce the volume after folding together, further.Superstructure is set
Meter is fairly simple, and focuses on the design of middle part floor truck structure.The design of middle part floor truck structure, to realize carrying
, by the addition of other structures, difference in functionality is realized as agent structure in the position of function.The design of substructure, then only have
Dismountable foot stool composition for stepping on car stretcher automatically.
2nd, main body frame structure
This handbarrow needs the two of which function of realizing to be exactly floor truck function and step on car stretcher function automatically.This two
Individual function is relevant with middle part floor truck structure.
In terms of structure design, it is contemplated that arriving, because top Folding stretcher part is directly to use existing military four
Folding stretcher is rolled over, its size shape is substantially stationary, therefore in the design of frame width, it is ensured that vehicle frame steadily can firmly be put
Stretcher structure is put, in the design of width, the width of stretcher is adapted to, makes it have good linking ability.In terms of width, two
The inside spacing of root longeron is 600mm, it is necessary to the convenience used in view of it in terms of length, length directly not with stretcher
Length linking, be 1200mm in Design of length.Between longeron, it is attached by five crossbeams, five center section is again
Connected by the beam longitudinal phase of two roots and crossbeam cross section formed objects shape, constitute the structure of multiple sphere of movements for the elephants shapes, it is ensured that carrying
It can be evenly distributed in total amount.Two longerons are because the relation of main body load-bearing, size is larger, and the high 51mm in cross section, wide 31mm are middle
Progress take out shell processing, reserve 1mm thin-walleds, centre is emptied and not only saves material, and mitigate weight, can slot milling place other
Structure, especially stretching structure.Meanwhile, middle crossbeam and longeron carry out emptying processing simultaneously.In crossbeam and middle longeron
Muscle structure is provided below, can effective lift structure bearing capacity.
The thickness of five crossbeams and the longeron of centre is all relatively thin for the load-bearing longeron on both sides, and bottom can be installation
The corresponding space that other structures are reserved.
The tail structure of main body frame structure is three-stage telescopic structure.
In vehicle frame afterbody, the load-bearing bull wheel of handbarrow is installed.Tire outside diameter is 250mm.Rear portion giant tyre is not direct
Installed in the afterbody of longitudinal beam, but independently as a component, a thicker connection is installed between two giant tyres
Steel pipe, increases the bearing capacity of tire, and the shearing applied when aiding in bearing goods on vehicle frame to structure.In the middle part of connecting rod and
In the middle part of tire a distance away, the height of vehicle frame after load-bearing giant tyre is installed from the ground is made to have certain increase, it is possible to increase car
Frame and the distance on ground, are also for car stretchers such as instrument realizations to the adaptability in place during hoisting tool realization carrying function
Folding tripod has enough spaces to place after folding during function.
In the tire weighted design structure at rear portion, there is " an increasing " part, medium design is fluted, can just put car into
The longeron of frame, connects vehicle frame and rear portion tire device, and be fixed by bolt., can be with using detachable design
Shi Jinhang is dismantled, and the parts of damage are replaced.
The two simple frameworks, constitute the whole most basic part of intermediate handling dolly module section, the most core
Part, objective function can not be now realized certainly, passes behind and adds other structures successively, can gradually realize that other are corresponding
Function.
3rd, stretching structure
In order to ensure the length when realizing structure length when stepping on vehicle bridge function and realizing handbarrow simultaneously, we determine to adopt
The stretching structure of three-stage is taken, and the structure type of pull bar luggage truck can be equally used for reference on stretching structure, it is vertical in both sides
The form of expansion link is taken on beam, the flexible of structure is carried out, and vehicle frame afterbody is the matrix of stretching structure, middle and anterior
Expansion link can be designed in the inside of longitudinal beam.
The expansion link design length at middle part is 1200mm, and front side length of telescopic bar is designed as 1100mm（Do not include foremost
Handrail）, two expansion links of front side are connected by handrail, and middle part expansion link both sides are then individually present.
In terms of connection, have flexible between middle part connecting rod and main body frame, between front side connecting rod and middle part connecting rod
Also retractable.It is also as stepping on vehicle bridge function in use, whole instrument possesses 3500mm length when extending to most long
Between degree, each two stretching structure, the most short coincidence distance for possessing 100mm, it is ensured that expansion link can bear phase when being pulled to most long
The weight answered.It is reduced to most in short-term in structure, middle part expansion link leaves 100mm distance in frame outside, front side expansion link is then complete
Portion is contracted to inside the expansion link of middle part, and length now is well suited as length during handbarrow.
In the cross section design of expansion link, the height of front side expansion link cross section and the height of middle part expansion link cross section
Compared to difference very little, the outer wall of front side expansion link will almost fit with the inwall of middle part expansion link.And middle part expansion link cross section
Height compare the cross-sectional height of longitudinal beam for, then want that short upper 10mm is more, its purpose is to can add below
Other structures, realize other functions, such as support foot rest needed for metamorphosis function.
In the design of front side handrail, most center section cross section is smaller compared to for two ends, and the purpose is to can be upper
Quick-locking device is installed in face, and effect is the instrument as achievable and truck afterbody fast lock on front side of instrument when stepping on vehicle bridge function
Tightly.
4th, metamorphosis structure
Three kinds in structure of the present invention are carried form, i.e. folding two-wheel form, tilt four-wheel form and keep flat four-wheel form.Three kinds
Form is carried, different measurement of cargo and form has been corresponded to.The first form can carry a small amount of goods, be similar to and draw with form
The occupation mode of bar luggage truck.This form is also same as using when instrument is individually dragged simultaneously.Second of form makes manpower
Use it is relatively small, can deliver oil drum or other compared with parcel.The third form can carry a large amount of loose mails or relatively large goods.
The first is carried form and can be directly realized by with the structure type of stretching structure, as needed, and front side expansion link leads to
Freely adjusting for length is crossed, suitable length is reached, while most front side is used as handrail.
Structure before second of carrying form and the third carrying direct use of form can not be then realized, it is necessary in workshop
Add tire in front side.Simultaneously in view of both forms, determine to add truss structure in frame downward, and truss structure can be around car
Frame afterbody is rotated, the leading portion both sides addition universal wheel of truss, and four-wheel form is constituted with the load-bearing tire at rear portion.On front side of truss
Between vehicle frame, it is attached by the expansion link of rotatable locking.When truss is rotated, the length of telescoping tube is also therewith
