Description

A kind of power-assisted stair-climbing car

Technical field

The utility model relates to boosted vehicle, specifically, is a kind of power-assisted stair-climbing car, belongs to consumer goods industries.

Background technology

Along with commodity retail mechanism is increasingly mature, delivery at door has become the critical services mode of retailer, and commodity will be delivered in customer family by deliveryman, very arduous, when particularly customer lives in the common multi-storey building not having ground elevator, deliveryman's heavy burden is gone upstairs very difficult, and labour intensity is very large, and deliver goods amount is also limited, such as drink water deliveryman, once can only resist one barrel of water, if a unit has many families to purchase water, deliveryman then will come and go repeatedly upper and lower stair, water could have been sent.

Summary of the invention

The purpose of this utility model is the deficiency for above-mentioned technology, provide a kind of structure simple, flexible, time saving and energy saving send water power-assisted stair-climbing car.

The technical solution of the utility model is: a kind of power-assisted stair-climbing car, comprises wheel, chassis, compartment, actuating device, driving device; Described wheel comprises a pair front-wheel and front wheel spindle, pair of rear wheels and hind axle, is connected with the axletree bearing be arranged on chassis by axletree; Described compartment is fixed on above chassis; Described actuating device, driving device are arranged on chassis; Described wheel is three horn rings, the wheel hub of this three horn ring has three legs, is uniformly distributed, radially in circumference.

Described actuating device is made up of DC machine and storage battery.

Described driving device is chain gearing, be made up of sprocket wheel, messenger chain, tween drive spindle, described sprocket wheel comprises the driving wheel be arranged on DC machine output shaft, three row power wheel, the front driven wheel be arranged on front wheel spindle, the back front driven wheels be arranged on hind axle be arranged on tween drive spindle, realize Chain conveyer with three messenger chains, the transmitting ratio of forward and backward flower wheel is consistent.

Described DC machine is furnished with forward and backward operating switch.

Described compartment is provided with handrail hand handle.

The beneficial effects of the utility model are: structure of the present utility model is simple, time saving and energy saving, flexible, manufacturing cost is lower, upper convenient downstairs, can disposable transport many barrels of water, greatly can alleviate the labour intensity of workman.

Detailed description of the invention

Shown in Fig. 1,2, a kind of power-assisted stair-climbing car, comprise wheel, chassis, compartment 5, actuating device and driving device, compartment 5 is fixed on above chassis, wheel is arranged on the both sides on chassis, and actuating device and driving device are assemblied on chassis, corresponding compartment 5 lower position.

Compartment 5 is rectangular frame structure, base of frame corner has four supporting legs, compartment 5 width mates with the width on chassis, the side in compartment 5 is provided with handrail 9, the curved baffle 6 that polylith mates with bucket is provided with in compartment 5, make in bucket can be placed horizontally at the bottom of railway carriage or compartment, compartment 5 and baffle plate 6 is formed space, bucket location is reliable; Bottom compartment 5, two supporting legs of rear end are longer than two supporting legs of front end, and bottom making compartment 5, rear end is inclined upwardly, and arrange like this and can avoid meeting accident climbing in building process the layback of bucket roll tilt; Four described supporting legs are fixedly connected with the bearing seat 4 on chassis respectively.

Described actuating device is made up of DC machine 11 and storage battery 12, DC machine 11 and storage battery 12 are all arranged on chassis, storage battery 12 provides power for DC machine 11, motor 11 source switch 8 and forward and backward operating switch are positioned at the handrail 9 hand handle place on compartment 5, handled easily controls, change motor 11 forward and backward direction to control three horn ring 3 hand of rotation by change-over switch 10, thus produce advance or backward movement.

Described driving device is chain gearing, by sprocket wheel, messenger chain, tween drive spindle 16 forms, sprocket wheel comprises the drive sprocket 7 be arranged on DC machine 11 output shaft, be arranged on three row's driving chain wheels 15 on tween drive spindle 16, be arranged on the front idler sproket 1 on front wheel spindle 2, be arranged on the rear driven sprocket 13 on hind axle 14, before tween drive spindle 16 is positioned at, between hind axle 14, pass through messenger chain, before three row's driving chain wheels 15 connect respectively, before on hind axle, rear driven sprocket 13, three row's driving chain wheels 15 are connected with the drive sprocket 7 that motor 11 output shaft is arranged by messenger chain again, namely motor 11 by drive three row's driving chain wheels 15 thus drive before, rear driven sprocket, before, the transmitting ratio of rear driven sprocket is also consistent.

Wheel comprises a pair front-wheel and pair of rear wheels, and front-wheel is fixed on front wheel spindle 2 two ends, and trailing wheel is fixed on hind axle 14 two ends, and front wheel spindle 2 and hind axle 14 are installed on the bearing seat 4 on chassis respectively, and wheel is driven by motor 11; Described wheel is three horn rings 3, the wheel hub of this three horn ring 3 has three legs, and three legs are uniformly distributed in the circumference of wheel hub; radially; the end of every leg and earth surface is set to arc, in order to increase friction and protection wheel body, can arrange in rubber wheel case is wrapped at arc part.

When the utility model uses, after arrival entry to the stair, first multiple bucket is placed on baffle plate 6 place, compartment 5 fixes (as stair are too precipitous, slightly can bundle with rope), hold handle and power-on switch 8, power is passed to three row's driving chain wheels 15, forward and backward driven sprocket 13 and transmission shaft by drive sprocket 7 by electrical motor successively, by the rotation of drive three horn ring 3, realization is climbed building action by the rotation of three horn rings 3, after arrival designated floor completes and send water, use change-over switch 10, make electrical motor contrarotation and three horn rings 3 are retreated, can go downstairs.
