Description
The utility model relates to a kind of motor moped that can be used for climbing building or level land use.
Current people overcome weight to be difficult to difficulty upstairs, adopt the wheeled go-cart of star mostly, but this infrastructure cost height, the stationarity of going upstairs is poor.Chinese patent 95224007.6 discloses a kind of and the wheeled baggage car, and employing and wheel and overlapping form of taking turns constitute running gear, reach the purpose of carrying article by the different connection modes of pull bar and vehicle frame.Though this structure can improve the ability of goods by stair, roller requires many, and the weight of corresponding baggage car also just increases, and cost is also high.
The purpose of this utility model is the deficiency that overcomes foregoing invention, provides a kind of cost low, simple in structure, lightweight stairs and flat land dual purpose car.
The utility model is realized above-mentioned purpose by following measure.
The utility model is except that containing support 6 and being provided with on support the wheel shaft 8,7 of front and back, principal feature is to be provided with big or small two pair rollers 4,3 on hind axle 7 side by side, front wheel spindle 8 is provided with a pair roller 1, and wherein the trundle on the hind axle 3 is connected by crawler belt 5 with trundle 1 on the front wheel spindle 8.
The utility model can also be established several cylinders 2 at crawler belt 5 inner bottom parts, and cylinder 2 is fixed by the supporting case of the no end that is located on the antero posterior axis 8,7.The diameter of roller 4 is greater than roller 3 diameters and crawler belt 5 thickness sums.
Below in conjunction with drawings and Examples the utility model is elaborated.
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model planar view.
Among the figure 1, front-wheel 2, cylinder 3, trundle 4, big roller 5, crawler belt 6, support 7, rear axle 8, front axle 9, supporting case of the no end side by side side by side
Make support 6 at support 6 with corrosion-resistant steel or other material, on establish before and after wheel shaft 8,7, on hind axle 7, establish big or small two pair rollers 4,3 side by side, establish roller 1 on the front wheel spindle 8, roller 1 is connected by crawler belt 5 with roller 3, for preventing the elastic deformation of crawler belt 5 when climbing the building, the inner bottom part of crawler belt 5 is provided with 1～3 cylinder 2, cylinder 2 is fixing by the supporting case of the no end 9 that is located on the antero posterior axis 8,7, the resistance when using for the minimizing level land, and the diameter of roller 4 is greater than the diameter and the crawler belt 5 thickness sums of roller 3.When use on the level land, have only roller 4 bearing goods that contacts to earth to roll, if need climb the building time, crawler belt 5 and cylinder 2 at first contact stairway step, drive roller 1,3 and rotate, and contact to earth up to roller 4, and so the cycle increases the building ability of climbing of dolly repeatedly.
The utility model is simple in structure, and is in light weight, and it is laborsaving to climb the building, also can use on the level land.
