Heavy articles are conveyed to the destination, time is saved, and labor is saved.

Description

The Stairs climbing vehicle structure

The utility model relates to a kind of Stairs climbing vehicle structure, is meant a kind of wandering star type circle wheel Stairs climbing vehicle that is provided with motor especially.

Generally saving strength by hand barrow when having carrying heavy goods now, as shown in Figure 7, is the structure of general hand barrow 1, and it holds thing plate 11 and support 12 installs to being the L type, and support 12 bottoms have extended a nose bar 13, in nose bar 13 third sides roller 14 are housed.This car can be passed for loading and use, but it only is applicable on the flat road surface and operates, use is just felt inconvenience deeply, is jolted and be difficult to walk on rugged road, especially weight is carried out upstairs, when moving downstairs, this car just can't by, can only shoulder with manpower, carry, carry on the shoulder, waste time and energy with lifting and move and could realize.For example carrying gaholder, to enter walk-up high-rise building be exactly that a headachy hard and unprofitable job makes.

The purpose of this utility model provides a kind of Stairs climbing vehicle structure, and it is the wandering star type circle wheel of installing on car body by driven by motor, climbs floor or carries out on rugged road the saving manpower.

The utility model is made up of bridge 2, base plate 3, wandering star type circle wheel 4, reductor motor 5 and storage battery 6, it is characterized in that: the bridge 2 that is welded by several bodies of rod, its upper end is formed with holding rod 21, the lower end weldering is provided with base plate 3, base plate 3 both sides extend upward two locatings plate 31, are equipped with a frame plate 32 in the interior rear end of a locating plate 31; Wandering star type circle wheel 4 is by triangle wheel carrier 41, form through bolt 421, nut 422 fastening three rollers 43; The hole 311 that locating plate 31 rear sides are installed is for wheel shaft 44 is installed, and two wandering star type circle wheels 4 are installed in wheel shaft 44 two ends from both sides, and fixes it, the composition Stairs climbing vehicle with spring cotter 45; Reductor motor 5 is packed on the frame plate 32 of base plate 3, be fixed with a driving gear 52 on its output shaft 51, this gear 52 is meshed with driven gear 53 on being positioned at wheel shaft 44, driven gear 53 is provided with an electromagnetic clutch 54, and the power supply of this motor 5 is supplied with by the power supply 6 of 61 li of the storage boxes that is packed in bridge 2 rear ends; Storage box 61 is provided with source switch 62, start button 63 respectively with holding rod 21 places.

When using at ordinary times, magnetic clutch 54 is not connected with driven gear 53, draws so car body can freely before postpone, and the M/C loading is used.When desire climbing floor, first power-on switch 52, the started by press button 53 again, 54 adhesive driven gears 53 of magnetic clutch, reductor motor 5 runnings simultaneously drive car body delivery weight speeling stairway and advance.

The utility model characteristics be can rugged and rough, the drop height is arranged or has and solve the difficult problem on the road surface of obstacle.The utility model the wandering star type circle wheel of special tool replace automatically and creep, be aided with motor-driven again, both saved time, laborsaving again, operation only needs its sense of motion of control, can remove weight to the destination.In addition, this device also has suitable brake, anti-on-slip drop function, can prevent when climbing ladder, and object takes place because of action of gravity causes the unexpected phenomenon of car load tenesmus landing.

At first, consult shown in Figure 1, the utility model mainly be by bridge 2, base plate 3, wandering star type circle wheel 4, reductor motor 5,, storage battery 6 parts such as grade are formed.

By the bridge 2 that several bodies of rod are welded, its upper end is formed with holding rod 21, and the lower end weldering is provided with base plate 3, and base plate 3 both sides extend upward two locatings plate 31, are equipped with a frame plate 32 in the interior rear end of a locating plate 31; Wandering star type circle wheel 4 is by triangle wheel carrier 41, form through bolt 421, nut 422 fastening three rollers 43; The hole 311 that locating plate 31 rear sides are installed is for wheel shaft 44 is installed, and two wandering star type circle wheels 4 are installed in wheel shaft 44 two ends from both sides, and fixes it, the composition Stairs climbing vehicle with spring cotter 45; Reductor motor 5 is packed on the frame plate 32 of base plate 3, be fixed with a driving gear 52 on its output shaft 51, this gear 52 is meshed with driven gear 53 on being positioned at wheel shaft 44, driven gear 53 is provided with an electromagnetic clutch 54, and the power supply of this motor 5 is supplied with by the power supply 6 of 51 li of the storage boxes that is packed in bridge 2 rear ends; Storage box 61 is provided with source switch 62, start button 63 respectively with holding rod 21 places.

During with above-mentioned detail assembly, see also Fig. 2, shown in Figure 3, its reductor motor 5 suitably is packed in the car body rear side with storage battery 6, and initiatively, driven

gear

52,53 is meshed, projection has a fixture block 33 on base plate 3, cooperate tying up of buckle-up 7 again, and bridge 2 both sides face down bondings are provided with two side pins 22, safer when making the carrying gaholder.When using at ordinary times, magnetic clutch 54 not with the driven gear adhesive, draw so car body can freely before postpone, do general manual loading and use; When desire climbing floor, elder generation's power-on switch 62, the started by press button 63 again, magnetic clutch 54 just with driven gear 53 adhesive mutually, reducing motor 5 runnings simultaneously drive car body automatically, 8 displacements of carrying heavy weight gaholder are advanced, and speeling stairway and rugged road are especially convenient when adjourning obstacle.

Shown in Figure 4 is the action scheme drawing of the utility model speeling stairway.When the Stairs climbing vehicle loading was gone upstairs, three rollers 43 of its wandering star type circle wheel 4 can be replaced automatically along stair or for fulcrum or for action wheel ground and creep.Make that the work of moving weight can save time, unblocked finishing effortlessly.

As shown in Figure 5, the utility model can be the electronic Stairs climbing vehicle of GENERAL TYPE, and its base plate 3 directly extends forward, is tabular and the fixture block 33 that not have to give prominence to, and bogie side frame 22 is the rear sides that are welded on bridge 2, can be used for carrying various items.

As shown in Figure 6, the utility model also can be assembled into the simple type hand propelled Stairs climbing vehicle of not equipping reductor motor 5 and storage battery 6 parts, also has identical effect in the time of on loading climbing floor and the crankcase ventilaton of advancing.
