The utility model is characterized in that both ends of the curving shaft [4] are provided with a wheel frame [2], a wheel plate [7] is arranged on both ends of the wheel frame [2], and both ends of the wheel plate [7] are respectively provided with a wheel [3]. The utility model has the advantages that the utility model can successfully overcome obstacles of the steps of the stairs and can climb a higher floor under the action of the drag force of a carrier on the premise of a limited weight load, for example, the utility model can successfully convey a household liquefied gas tank to an upper floor, and the vehicle can also smoothly run on a flat.

Description

A kind of floor truck of energy stair climbing

Technical field

The utility model belongs to a kind of manpower instrument, particularly a kind of floor truck of energy stair climbing.

Background technology

At present also do not have the resident family of pipe laying coal gas for staying in the building the inside, cooking in the daily life heats up water waits in the cooking activity most use autogass source that acts as a fuel.And home-use autogas comes splendid attire with liquefied petroleum gas steel cylinder, general total weight is between the 25-35 kilogram, the general user will change one time liquefied gas bottle in almost per 1～2 month, this replacing can only with artificial pickaback or two people way of lifting carry out, be very much hard, for unwell people, also has certain danger.Also do not see in the present market and thisly can be transported to the instrument that goes to cylinder for liquefied gas smoothly upstairs.We have also retrieved the data of part, find No. 92239651.5, Chinese patent, and name is called: the liquid gas storage tank transport trolley.This wheel is provided with "+" font wheel carrier of energy stair climbing, and the top at the wheel carrier support arm is equipped with landing wheel by wheel shaft.We are through conscientious research, think that this imagination is fine, but since its "+" character wheel frame when going upstairs between two landing wheels distance distant, and the very big vibrations of generation, often make the cylinder for liquefied gas that is handled upside down shake, even fall down, and in walking, can send very big noise, have influence on the resident family in the building.For can be smoothly cylinder for liquefied gas under bringing up on the stair and transporting, inventive concept scheme of the present utility model has been proposed.Just the purpose of this utility model provides a kind of floor truck of energy stair climbing.

Summary of the invention

The floor truck of this kind energy stair climbing, but it has the vehicle frame [1] of a support weight, have straight joist [5] and curved joist [6] on the vehicle frame [1], the bottom of vehicle frame [1] is a cambered axle [4], the two ends that it is characterized in that cambered axle [4] have wheel carrier [2], at the two ends of wheel carrier [2] wheel plate [7] is housed, a wheel [3] is respectively arranged at the two ends of wheel plate [7].Its advantage is under the limited prerequisite of bearing a heavy burden, and under the effect of bearer's traction force, can successfully overcome the obstacle of stairway step, climbs up than higher floor.Go such as can smoothly household liquified gas tank being transported to upstairs.This car can also move on flat ground by pulsation-free.

Description of drawings

Accompanying drawing 1 is a structural front view of the present utility model, and accompanying drawing 2 is left views of accompanying drawing 1, and accompanying drawing 3 is birds-eye vieies of accompanying drawing 1, and accompanying drawing 4 is partial enlarged drawings of wheel [3] and wheel plate [7] and wheel carrier [2].Sequence number in the accompanying drawing is: 1, vehicle frame, 2, wheel carrier, 3, wheel, 4, cambered axle, 5, straight joist, 6, curved joist, 7, wheel plate.

The specific embodiment

With reference to accompanying drawing, the floor truck of a kind of energy stair climbing of the present utility model, but have straight joist [5] and curved joist [6] on the vehicle frame of its support weight [1], so that adapt to the needs of different carrying objects.For carrying during as heavier He more special article such as cylinder for liquefied gas, can be on vehicle frame suitable position with rope or other analogue sealing such as clamp once is convenient to transport safely.In the bottom of vehicle frame [1] is a cambered axle [4], has wheel carrier [2] at the two ends of cambered axle [4], this wheel carrier [2] can go for a stroll the axle [4] freely rotate.At the two ends of wheel carrier [2] wheel plate [7] is housed, this wheel plate [7] is installed together by a rotating shaft and wheel carrier [2], and each wheel plate [7] can freely rotate being installed in the rotating shaft on the wheel carrier separately.At the two ends of wheel plate [7] a rotary wheel [3] is arranged respectively.When using is such: (being example with common stairway step (high about 14 centimetres, wide about 29 centimetres)) puts into the inside, space that cambered axle and curved joist and vehicle frame form with cylinder for liquefied gas, and the thing of the most handy rope one class with its sealing once.When drawing dolly to go upstairs, vehicle frame [1] and cambered axle [4] can rotate around wheel carrier [2].Top one group of wheel is run into the high 14 centimetres facade of first order step earlier, continue firmly, because the wheel plate of first group of wheel can rotate by the axle on wheel carrier, continue under the pulling firmly at this, because the combined action of the power and the arm of force, first wheel will be climb along the facade of step, and then drive second wheel and go ahead, continue upwards to draw, just can be so that the facade that second wheel also climbed to step gets on, at this time, the weight of dolly and top cylinder for liquefied gas is mainly born by two wheels of back.Pull on then, forward on the wide 29 centimetres plane of second layer step up to the facade of two wheels of fwd from step, at this moment two of the back wheels are also followed up, advanced to the facade of ground floor step, pull on, the wheel of back just repeats the course of action of fwd wheel just now, walks on the facade of ground floor step, two wheels up to the back have been climbed on the plane of second layer step, have just finished a complete action of climbing step.Just repeat this process later on,, go up upstairs up to climbing complete step.In the level land, 8 wheels of dolly all contact with ground, therefore also can move by pulsation-free, just can guarantee walking as long as there are two wheels to contact with ground theoretically.By the way, this dolly need not just can draw a lot of things upstairs through complicated improvement.
