Description
Technical field the utility model provides a kind of small-sized stair, ground handling instrument, is applicable to the carrying of extraordinary stair such as daily life, industrial stair and tourism mountain-climbing ladder.
The existing residential building of background technology is mostly with daily necessitiess such as the various grain and oil of manpower transport, gas tanks, general resident can't stair activity with dolly and travelling dolly, and most of stairs clambing handcart is because of existing that price is higher, the object of carrying is big, structure is too cumbersome, drawback such as cumbersome operates, particularly some transport trolley only is applicable to the stair walking, and show slightly clumsy at the stair turning, less flexible again when on the level land, walking, so stairs clambing handcart is not popularized in daily life.The stair handling car that most residents wish be cheap, easy to use, can carry some life article, light little level land and stair dual-purpose floor trucks simple in structure substantially.
It is lower that the summary of the invention technical problem to be solved in the utility model provides a kind of cost, carries some basic daily necessitiess and light little ground, stair dual-purpose hand push (drawing) floor truck simple in structure.Be applicable to the carrying of tourist attractions carry-on articles such as mountain-climbing ladder etc. simultaneously, the industrial stair of also can walking are carried the light-duty raw material of industry, therefore have suitable application area wide, characteristics such as be easy to popularize.The utility model is made up of Foldable handlebar, jugged rolling wheel, jugged rolling wheel axle, under-carriage, roller shaft stay bearing plate, main wheel, main axle, folded bicycle fence etc.Two the main wheels in back land similar barrow during the dolly level walking.During the dolly stair activity, rely on the jugged rolling wheel walking, roller blocks the stair edge, make dolly reduce vibration and keep stability, the jugged rolling wheel of broad also increased and stair between contact surface, make the corner of stair injury-free.Dolly has utilized the human body stair activity to push away (drawing) thing characteristic and related data, makes its natural transition of energy from the level land to stair, must not cross multioperation, and it is very convenient therefore to use.
Description of drawings (1) is the front view of this car embodiment, and figure (2) is a birds-eye view, and the drawing ratio among two figure is 1: 10.Figure (3) is the jugged rolling wheel cross-sectional view, and drawing ratio is 1: 1.
The specific embodiment is below in conjunction with the function of this dolly of block diagram illustrating.
Mainly consisting of of this transport trolley: (1) Foldable handlebar, (2) jugged rolling wheel, (3) jugged rolling wheel axle, (4) under-carriage, (5) roller shaft stay bearing plate, (6) main wheel, (7) main axle, (8) folded bicycle fence.
Dolly basic structure is: as accompanying drawing (1), under-carriage (4) is a framed structure, weld or install roller shaft stay bearing plate (5) below, Foldable handlebar (1) and folded bicycle fence (8) are installed in top, two main wheels (6) are installed in the rear portion of under-carriage, by main axle (7) and bearings, jugged rolling wheel axle (3) is installed on the roller shaft stay bearing plate (5).Scheme medium and small skiving shape roller shaft and amount to 19, be divided into two kinds of length, two ends are threaded.In accompanying drawing (1), all jugged rolling wheel axles distribute at grade, and are parallel to each other.In accompanying drawing (2), distance between the adjacent rollers axle (3) equates and is slightly larger than the roller radius, in two adjacent axles, two rollers that width is identical are housed on one, are distributed in both sides, a wheel is housed on another root wheel shaft, in the middle of being distributed in, roller is staggered arrangement and breast wheel and two side wheels and separates with shelf, and all jugged rolling wheels (2) have the identical flute profile and the number of teeth, and the diameter of the centre hole of roller is greater than the diameter of roller shaft.Jugged rolling wheel adds up to two nineteens among the figure, and cross-sectional sizes is identical with shape, and the jugged rolling wheel number of teeth can be 18, and tooth depth is 5 millimeters.
During the dolly ground running, draw the related data of (pushing away) car and the design of dolly handlebar shorter according to human body, so carry on the anterior nature of dolly, main wheel this moment (6) lands, the equal built on stilts of all jugged rolling wheels, dolly relies on main wheel to walk on the ground down people push away (drawing).
When dolly is gone upstairs, must the people draw dolly forwardly, because the people goes upstairs earlier, dolly is carried on carrying on original on the basis once more, make jugged rolling wheel touch first order ladder naturally, jugged rolling wheel (2) and the interlock of stair edge, draw before the dolly, roll behind the roller, this moment, main wheel did not contact stair, and the edge that makes roller and stair that is staggered of jugged rolling wheel always is in interlocking pattern, this state can increase the contact surface of roller and stair effectively and reduce slide relative between the two, roller can utilize rubber or duroplasts to make, and can reduce the up-down vibration of dolly like this, and dolly is walked on stair the labour-saving very much.Dolly design roller total length is at least greater than the distance of three rank stair cases, and all jugged rolling wheels of dolly should be in one plane, when all rollers of dolly are placed on the level ground, main wheel and ground distance greater than tooth depth of jugged rolling wheel less than two tooth depths.In dolly when design, require people the place ahead of average height to push away (drawing) dolly, and the height that dolly is carried should be able to make main wheel land, and all jugged rolling wheels all should built on stilts, and the height that dolly is carried should be able to make first roller of the place ahead be higher than the height of single order stair.When dolly arrives the stair end or stair gap, when last group jugged rolling wheel blocks the stair edge, because the people has stood on the level land, lower in the dolly front portion, draw before the continuation roller is removed, main wheel arrives the stair edge, continues to support dolly by two main wheels.When going downstairs, dolly should be carried out, because people's push-and-pull dolly degree of raising is different, utilizes this point that dolly is walked on stair naturally.
When dolly left unused, handlebar, rear end vehicle frame and both sides vehicle frame all can be relative inwardly folding, and this moment, dolly was a plank frame, so that store or transportation.When dolly used, handlebar, rear end vehicle frame, both sides vehicle frame were folded and are opened successively, and connect by hinge, and it is unrestrained to prevent goods to install grille guard in the car frame additional.
