Abstract
The utility model designs a crawler type transportation vehicle suitable for carrying goods on field pathways, which belongs to the technical field of a trackless land vehicle and can walk on field ridges and narrow meandering footpaths of mountain ground or hills. Two crawlers of the walking part of the crawler type transportation vehicle are provided with small space, the inner sides of the bottom faces of the crawlers are slanted into a shape like the Chinese character 'ba', and each crawler is largely suspended up at the front and the back parts of the crawler type transportation vehicle. When the utility model walks on a narrow and rugged road, the small space of the two crawlers ensures that a narrow road tread can not be immersed between the crawlers, and a crawler structure in the shape like the Chinese character 'ba' can make the crawlers and the road tread keep contact at multiple points so that a vehicle body keeps stable; when the utility model walks on steps with small upper and lower width and larger height, the largely suspending parts of the front ends of the crawlers can be in contact with ribs of the steps and then the crawler type transportation vehicle climbs on the steps through the grabbing force of the crawlers for the ribs.
Description
Affiliated technical field
The crawler-type carrier vehicle that is suitable for loaning belongs to the trackless terrestrial vehicle technical field, is chiefly directed to the light transport trolley of walking on ridge in mountain region or the hills, the narrow winding trail.
Background technology
At present, the vehicle that can travel in mountain region and hills mainly is a wheel barrow.This kind vehicle needs manpower to promote, and makes it held stationary.This vehicle load is limited, and is not suitable for the rough road surface of big step or projection and hollow.Some proprietary designs several crawler type handcart capable of travelling up stairs (as the patent No.: 88200864.1,90209459.9 and 94212545.2 etc.), but they only are suitable for having the flat road surface of step, and the road surface that is fit to is with respect to the general broad of vehicle body.
In vast rural area, the peasant need transport fertilizer, cereal etc., must be through narrow and unmade way, as ridge etc., also need to stride across ditch sometimes, the step that upper and lower width is not quite and highly bigger.Therefore press for and a kind ofly on this kind road surface, walk, can carry the transport facility of certain load simultaneously.
Summary of the invention
At the problems referred to above, the utility model has designed a kind of crawler-type carrier vehicle.This transport trolley can not only be in the walking of narrow and unmade way, and can stride across ditch, the step that upper and lower width is not quite and highly bigger, and can carry constant weight.
The technical scheme that its technical matters that solves the utility model adopts is: two crawler widths of transport trolley crawler body are big and spacing is less and the inner side surface that contacts with the road surface partly is inclined to " eight " font, every crawler belt parcel four wheels, each supports (these axles directly or by support are connected with car body) with corresponding axle this four wheels, being distributed in one falls on four trapezoidal summits, make every crawler belt area surrounded be trapezoidal, crawler belt has bigger hanging in car front portion and car rear portion.
The beneficial effects of the utility model are, transport trolley is when narrow and unmade way walking, and the design-calculated structure makes crawler belt keep many places contact with the road surface, and the assurance vehicle body is steady; When striding across ditch, because the center of gravity of car at the middle part of vehicle body, before the opposite bank of the anterior contact of crawler belt ditch, needs only center of gravity and do not enter on the ditch, car is fallen in the ditch with regard to not toppling, and can pass through ditch; When the not quite and highly bigger step of upper and lower width, the crawler belt front end is bigger has hanged part and can touch the step fin, and by " grip " of crawler belt to fin, makes the car climb steps.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the profile bottom surface sketch of crawler-type carrier vehicle;
Fig. 2 is the profile simplified side view of crawler-type carrier vehicle;
Fig. 3 is the crawler belt diagrammatic sectional view;
Fig. 4 represents being connected of wheel flutter and car body.
1. crawler belts among the figure, 2. adapter shaft, 3. wheel flutter, 4. compartment, 5. wheel, 6. spring, 7. strut bar, 8. bearing pin, 9. supporting base.
The specific embodiment
Among Fig. 1,2, two crawler belts 1 respectively are connected with compartment 4 by 4 wheels 5, adapter shafts 2.If the diameter of the wheel of crawler belt parcel is d
l, bottom two-wheeled centre distance is l, upper wheel is h to the vertical distance of lower wheels, 2h＞d
lThe angle of cut of the two-wheeled line of centres and the top two-wheeled line of centres is (if the angle of cut is 30 °, then two-wheeled centre distance in top is about l+2htg60 °) about 20 °～40 ° about the angle of cut of the anterior two-wheeled line of centres up and down and the top two-wheeled line of centres, the rear portion.The height that the utility model can be crossed step depends primarily on the size of h, and the maximum height that may cross step is h.
Adopt the closely spaced structure of broad track.Shown in Fig. 1,3, if vehicle body crawler belt portion width is W, crawler belt inner edge spacing
Every crawler belt is wide
Help in narrow road surface walking, the road surface minimum width is about S+10mm.
As shown in Figure 3, the inner side surface that crawler belt contacts with the road surface partly slopes inwardly, the sloping portion horizontal clearance be about single crawler belt wide 2/3rds, promptly
About 5 °～15 ° of degree of dip helps in the walking of rough road surface.
Steering hardware among Fig. 1 is a rotatable wheel 3 that is installed in middle part at the bottom of the car, rotatable angle 〉=90 °.As shown in Figure 4, wheel 3 is connected with strut bar 7 by bearing pin 8, and strut bar 7 is connected with supporting seat 9 by spring 6.Under the elastic force effect of spring, the wheel center height changes with pavement state.When spring was in relaxed state, the wheel flutter outer rim was protruded crawler belt appearance plane p
1During length of spring compressed extreme length p, the recessed crawler belt appearance plane p of wheel flutter outer rim
2, p=p then
1+ p
2
The utility model both can be promoted by manpower, can use mechanical power again.Power operated crawler-type carrier vehicle can be done power with combustion engine or electrical motor, and its carriage body construction should be very compact, is beneficial to be equipped with pass machinery.
