At present, part precision equipment needs level carrying, to protect device interior element.When equipment carries out stair carrying, if adopt a dead lift, cannot guarantee equipment level motion and be difficult for carrying.According to data searching, stair porter tool all cannot be realized goods in the level carrying of stair at present, and equipment handling process is not steady.
Summary of the invention
For solving above technical deficiency, it is a kind of easy to use that the utility model provides, and carries the horizontal transport trolley of stable stair.
The utility model is realized by following measures:
The horizontal transport trolley of a kind of stair of the present utility model, comprise vehicle frame base, described vehicle frame base bottom is provided with former and later two axletrees, the two ends of each axletree are provided with climbs wheel, described climbing wheel comprises with three most advanced and sophisticated starframes, axletree end is rotatably connected on the center of starframe, and three tips of described starframe are all rotatably connected to wheel; Vehicle frame base front end is provided with supporting seat, is rotatably connected to goods supporting plate on described supporting seat, and below, described goods supporting plate middle part is connected with the jack being fixed on vehicle frame base.
On the vehicle frame base of below, above mentioned goods supporting plate rear end, be provided with damping spring.
Above-mentioned vehicle frame base rear end is provided with driving handle, and vehicle frame base front end is provided with pull handle.
The beneficial effects of the utility model are: improve a kind of equipment of being convenient at the instrument of stair level carrying.Raising equipment and goods be in the efficiency of stair place level carrying, and be convenient to personnel and operate use.This device on level land and stair place all can use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1 vehicle frame base, 2 axletrees, 3 starframes, 4 wheels, 5 driving handles, 6 jacks, 7 goods supporting plates, 8 supporting seats, 9 pull handles, 10 damping springs.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done to further detailed description:
As shown in Figure 1, the horizontal transport trolley of a kind of stair of the present utility model, comprise vehicle frame base 1, vehicle frame base 1 bottom is provided with former and later two axletrees 2, the two ends of each axletree 2 are provided with climbs wheel, climb wheel and comprise that, with three most advanced and sophisticated starframes 3, axletree 2 ends are rotatably connected on the center of starframe 3, three tips of starframe 3 are all rotatably connected to wheel 4.Vehicle frame base 1 front end is provided with supporting seat 8, is rotatably connected to goods supporting plate 7 on supporting seat 8, and goods supporting plate 7 belows, middle part are connected with the jack 6 being fixed on vehicle frame base 1.On the vehicle frame base 1 of goods supporting plate 7 belows, rear end, be provided with damping spring 10.Vehicle frame base 1 rear end is provided with driving handle 5, and vehicle frame base 1 front end is provided with pull handle 9.
Working process is:
When the utility model transports on level land, starframe 3 two-wheeleds land and realize goods horizontal transport.When the stair place, front-wheel starframe 3 becomes single-wheel and lands and realize this car and go upstairs, and needs to regulate middle part jack 6 rising shipping supporting plates to make goods maintenance level in the process of going upstairs.This transport trolley advances process during to trailing wheel starframe 3 contact stair, trailing wheel starframe 3 changes single-wheel into and lands and realize this car and go upstairs, trailing wheel go upstairs after vehicle frame base 1 angle will remain unchanged, now, by goods supporting plate 7 debugging levels, with driving handle 5 and pull handle 9 these dollies of push-and-pull, just can realize goods and carry in stair place level.After goods supporting plate 7 is set level, damping spring 10 can play cushioning effect.
The above is only the preferred implementation of this patent; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the art of this patent principle; can also make some improvement and replacement, these improvement and replacement also should be considered as the protection domain of this patent.
