Abstract
The utility model relates to a multi-wheel dual-purpose cart which can be used on flat land and stairs, belonging to a civil machine. The utility model is composed of a cart frame (1) with a baffle plate (2) and a traveling mechanism. The utility model is characterized in that the traveling mechanism is composed of a large cart wheel (3) and two sets of small wheels (5) which are ranged in a staggered way and are arranged on small adjustable wheel frames (4), wherein a plurality of small wheels (5) are ranged into a plurality of rows. The small adjustable wheel frames (4) are connected to the cart frame (1) by an adjustable interlocking mechanism. When the utility model is used for climbing stairs, severe concave and convex phenomenon can not happen. The utility model has the advantages of little resistance, stable cart body, uniform force application and strong applicability.
Description
The utility model relates to a kind of level land of family's delivery weight that is applicable to and climbs the building motor moped, and the national is with mechanical.
Cart for travelling up or down stairs of the prior art has various ways, and its structure is different, and mostly being the level land on the function, to climb the building dual-purpose.Wherein the common disadvantage of Cun Zaiing is: the wheel diameter that 1, contacts to earth is big, and neutral gear is big between wheel, causes to occur bigger concavo-convex phenomenon in the stair climbing process behind the wheel and stair angular contact, and it is big to impact, and firmly inhomogeneous, the car body stationarity is poor.2, various cart for travelling up or down stairss can only be climbed the building with a fixing angle, and this difference of exerting oneself when having caused the different people of height to use is big, poor for applicability.More than 2 existing cart for travelling up or down stairss of explanation have to a certain degree defective, result of use is poor.
The purpose of this utility model provide a kind of applicability strong, firmly evenly, car body steadily and climb effective level land, building and climb the building motor moped.
The technical scheme that realizes the utility model purpose is: take turns the level land more and climb the building motor moped, form by vehicle frame that has plate washer (2) (1) and walking mechanism, it is characterized in that: walking mechanism is made up of car bull wheel (3) and two groups of a plurality of staggered steamboats of many rows (5) that are installed on the adjustable little wheel carrier (4), and adjustable little wheel carrier (4) is connected on the vehicle frame (1) by adjustable link gear.
The arrangement mode of many a plurality of staggered steamboats of row (5) is: many row's steamboats (5) are installed on the little wheel carrier (4), and each row has a plurality of steamboats (5), and adjacent two rows' steamboat (5) is alternative arrangement respectively.
Link gear is to constitute like this: little wheel carrier (4) one ends are rotationally connected with on the big axle rod (6), the other end is slidingly connected on the vehicle frame (1) by vehicle frame movable sleeve (7), two vehicle frame movable sleeves (7) are connected by cross bar (8), are connected with the adjust bar that is made of adjustable bolt (11) and nut (12) between cross bar (8) and the big axle rod (6).Also has hook (10) on the vehicle frame (1).
Advantage of the present utility model is: result of use is good, climbs not produce big concavo-convex jumping phenomena in the building process, and resistance is little, and vehicle body is steady, firmly evenly.By the use of adjusting angle applicable to different height people, applicability is strong.
Below in conjunction with embodiment shown in the drawings structure of the present utility model is elaborated.
Fig. 1, the utility model structural representation;
Fig. 2, the utility model vehicle frame (1) and link gear connection structure scheme drawing;
Fig. 3, the A-A cutaway view of Fig. 1;
Fig. 4, the arrangement architecture scheme drawing of the utility model steamboat (5).
Embodiment of the present utility model is with reference to shown in the accompanying drawing 1: vehicle frame (1) can be made by steel pipe, has the baffle plate (2) that can support weight above.Walking mechanism on the vehicle frame (1) comprises two car bull wheels (3) and is installed on a plurality of staggered steamboats of many rows (5) on the little wheel carrier (4).Its concrete structure and with the annexation of vehicle frame (1) with reference to Fig. 1, Fig. 2, Fig. 3, car bull wheel (3) is installed on the big axle rod (6) on the vehicle frame (1).Little wheel carrier (4) is connected with vehicle frame (1) by adjustable link gear.Its implementation is: little wheel carrier (4) one ends are inserted in bull wheel axostylus axostyle (6) by the opening on it and are rotationally connected with it, are positioned between two bull wheels (3), and are spacing by spacing shelves covers (9), and lining is with pad (13) between each parts.The other end of little wheel carrier (4) can slide up and down to be connected on the vehicle frame (1) by vehicle frame movable sleeve (7).Be rotationally connected by connecting rod (14) between movable sleeve (7) and the little wheel carrier (4).Two vehicle frame movable sleeves (7) are by cross bar (8) captive joint.Be connected with the adjust bar that constitutes by bolt (11) and nut (12) by two fixed covers (18) between cross bar (8) and the big axle rod (6).Nut (12) adopt be convenient to rotate apart from the shape structure, threaded one end is connected on the bolt (11), the other end is rotatably connected on the strut bar (15).
Steamboat (5) is installed on the little wheel carrier (4), by the fixing little wheel carrier (4) of clench nail (16).The installation arrangement mode of steamboat (5) on little wheel carrier (4) is with reference to Fig. 1, Fig. 3 and Fig. 4: many row's steamboats (5) are installed, and present embodiment adopts five rows.Every row has a plurality of steamboats, and adjacent two rows' steamboat (5) alternative arrangement make each wheel shaft (17) of every row's steamboat be positioned at gap between the wheel of adjacent row's steamboat.
On vehicle frame (1), also have in order to the fixing hook of weight (10).
When use on the level land, regulate link gear, two car bull wheels (3) are landed, and little wheel carrier (4) is affixed to vehicle frame (1), steamboat (5) need not.Implementation procedure is: setting nut (12), make to stretch on the bolt (11) to drive cross bar (8) along moving on the vehicle frame (1), and carry thereby drive on the little wheel carrier (4) by vehicle frame movable sleeve (7), be affixed to vehicle frame (1).Car bull wheel this moment (3) is stressed, can the front and back push-and-pull when use on the level land.
When climbing the building, opposite when using with the level land, setting nut (12) making the drive cross bar (8) that contracts under the bolt (11) move down along vehicle frame (1), thereby adjusting little wheel carrier (4) and the angle that the stair face contacts by vehicle frame movable sleeve (7), is adjusted to suitable angle.When end user's health was higher, the adjustment degree can be more greatly, and the angle of promptly little wheel carrier (4) and vehicle frame (1) more greatly.On the contrary, end user's height is less, and adjusting range is littler, makes little wheel carrier (4) littler with the angle of vehicle frame (1).So can satisfy different height people's use, strengthen its applicability.
Adopt the arrangement mounting means of miniature steamboat of the present utility model (5), make the wheel gap staggered little, constitute the plane.The wheel of steamboat (5) footpath is more little, arranges closely more, and effect is good more.During the operation of wheel contact stair, do not produce the convex-concave jumping phenomena, resistance is little, rolls steadily, makes pulling force keep balance.
