Abstract
The present invention relates to a carriage which can be run on staircase, sleeped pavement, slope and flat pavement and combines stepped pavement running structure and flat pavement running structure into one body. It adopts adjustable crawler belt, crawler and their brake mechanism for running on the staircase and stepped pavement, and front universal rubber wheels and rear type wheels with inflatable tubes for running on flat pavement and slope. When it is used for carrying baby, the baby bed can be added on the carriage frame, and when it is used for carrying goods, the goods carrier frame can be substituted for its original carriage frame.
Description
The present invention is the hand barrow that proposes a kind of brand new, and it can travel on the ladder step and the scenic spot ladder step of building, can travel on level road, the ramp again, and it is brand-new whole to be that two kinds of structures of travelling unite two into one.Extensible during operation, collapsible when stopping using.It is easy and simple to handle, flexible, operate steadily, safety, reliably be the act of present domestic initiation.
The technology of the present invention is achieved through the following technical solutions:
Ladder step hand barrow is by the vehicle frame assembly set
1.Annotate collapsiblely, see also Fig. 2,3, crawler belt location tension wheel,
2.Caterpillar chain,
3.Athey wheel,
4.The Folding pedal plate,
5.Preceding universal rubber wheel,
6.Back pneumatic tyre wheel,
7.Crawler belt, wheel, stop mechanism,
8.The combination of crank rotary positioning mechanism,
9.Crawler belt guide-localization wheel,
10.Deng composition, see also Fig. 1 ladder step hand barrow front view.
Its feature 1: car load ladder up operation of step;
When the ladder step, hand barrow needed up operation, the trammer must make the car load backward earlier back to the ladder step, and this moment, the people at the main car frame seat of honour also went on foot back to ladder.Because the car load backward is sailed, make the place ahead this moment, then originate to change and scratch the rotation of vehicle frame orientation angle and make preceding universal rubber wheel to rubber tire,
6.Change former ladder step hand barrow and locate preceding universal rubber wheel forward
6.Highly, reduce in the crawler belt guide-localization and take turns
10.Setting height.Pulling backward makes crawler belt guide-localization wheel again
10.Be rolled into terraced first ladder that goes on foot and go on foot the neighbour place, move the feasible back of handle (9-2) pneumatic tyre rubber tire at this moment
7.The crank positioning of rotating that connects is separated, and at this moment back pneumatic tyre rubber tire produces deadweight by gravity on the vehicle frame and rotation is shunk sagging.Annotate: the back air filled tyre connects with crank when Design Orientation and is offset certain angle, can make when after the pneumatic tyre rubber tire
7.When needing to shrink, just can make (9-7) to separate back pneumatic tyre rubber tire with (9-6) engagement as long as move handle (9-2)
7.Stressed rotation is shunk in vehicle frame
1.With crawler belt
3.Between the space.When travelling to ladder, car load goes on foot first and second ladder height and crawler belt
3.During hinge interface junction, draw on exerting oneself again this moment.At this moment pneumatic tyre rubber tire after
7.Being subjected to ladder step height resistance nature to be retracted to setting position with rotation locatees.When being retracted to desired location, decontrol the effect location that handle (9-2) makes its spring (9-4), at this moment can up spur.See also diagram 1,4,5.
Because vehicle frame combination
1.Two Athey wheels of last setting
4.Between apart from and form a squareness and ladder to go on foot angle similar.Crawler belt
3.Single-unit length is unsettled hypotenuse length between ladder goes on foot, and works as Athey wheel
4.Produce with crawler belt when being subjected to the external force pulling
3.The track rolling-operation.And crawler belt
3.Be subjected to Athey wheel
4.Rolling spreading application force make crawler belt
3.Generation goes on foot reciprocal Athey wheel with ladder
4.The race track is made crankmotion, reaches Athey wheel
4.With crawler belt
3.The rolling rotation running that goes round and begins again.Finish ladder upper and lower operation of step, parallel, steady, reliable effect.
Stair, ladder step ladder when making go on foot spacing, the height difference is big so ad hoc meter crawler belt
3.Be telescopic crawler belt.See also Fig. 1,4,5,6,7,8,9.
When running to ladder step on the car load during last ladder, move handle (9-2) this moment, engaging mechanism is separated.Pneumatic tyre rubber tire then
7.The rotation stretching, extension progressively contacts with ground by meshing the vehicle body deadweight of disengaging back.Car load break away from fully ladder must move repeatedly during the step handle (9-2) make its reach car load break away from fully the ladder step contact fully steadily with ground, safely, reliable effect.
This has gone up and has been up ladder step overall process.As on landing, having moved the process of one deck, when continuing up to move again as need.Just do the car load translation and go on foot direction around flat surface towards the last layer ladder on platform, later operation is with aforementioned.
Because crank rotary positioning mechanism
9.Middle locating wheel (9-7) is subjected to back pneumatic tyre rubber tire
7.And outstanding thumb (9-11) moment increases, and detent mechanism engagement separating force is bigger, and the first post of designed employing locating piece (9-6) (9-6-2) cylinder (9-6-1) positioning and rolling formula method reaches and makes handle (9-2) the less effect of power in use, pneumatic tyre glue after operation
7.When wheel is flexible, light reliable.See also Fig. 5.
Feature 2: car load ladder descending operation of step;
When the ladder step, the hand barrow car load was descending, car load was just in the face of the descending ladder step, when firmly advancing the descending nearly first descending ladder during step.It at first is preceding universal rubber wheel
6.Enter first ladder and go on foot the drop place, taken turns by the crawler belt guide-localization this moment
10.Stressedly roll forward, ahead running entered for the first descending ladder step again, when crawler belt 3. hinge locate with one voice when the ladder step, the first ladder way place combined, the crawler belt guide-localization is taken turns this moment
10.Advance into the first terraced drop place.Firmly touch downwards this moment, moves handle (9-2) detent mechanism separation simultaneously, when up after the pneumatic tyre rubber tire
7.Contraction principle is identical.Please read up back pneumatic tyre rubber tire
7.Shrink brief introduction.
Because descending power need be with equating toward upper pulling force, for reduce descending firmly and car load go on foot upper and lower operation at ladder and sail and can arbitrarily stop any position, so designed crawler belt, wheel stop mechanism (8), see also and illustrate 12.This is descending finish said method after, car load only needs light handles (8-2) make brake strip (8-9) be close to crawler belt when crawler belt, wheel operation
3., Athey wheel
4.Can make the car load deadweight lean on the track ramp rate with crawler belt
3.Track slowly travels down, parallel, steady, safe and reliable effect.
Car load in servicely only need be held handle (8-2) when needing to do to stop and can make car load stay in any position of ladder step immediately in ladder step.See also Fig. 1,12.
Feature 3: car load operates in level road, only need use single traveling mechanism when travel in the ramp, that is: vehicle frame combination
1., the Folding pedal plate
5., preceding universal rubber wheel
6.With back pneumatic tyre rubber tire
7.Get final product, when car load to overtake the time, hold handle (1-3) enforce forward operation can reach travel on, the effect in level road, ramp.See also Fig. 1.
Feature 4: change the vehicle frame combination into simple and easy lorry frame, just can be used for freighting and go up the descending stair step.
When the delivery baby uses, add that on vehicle frame the berch of baby structure gets final product.
The car load materials used is: 1, ferrous meatal; 2, hard aluminium alloy; 3, corrosion-resistant steel; 4, polyvinyl chloride; 5, rubber etc.
