Abstract
The invention discloses a simple manual carrying vehicle, which has the advantages of simple structure, low cost and convenient overhauling. The simple manual carrying vehicle comprises a vehicle body and a vehicle wheel axle, wherein an upper rocking rod, a lower rocking rod and a crank are hinged to the side wall of the vehicle body, a vertical strip hole is formed in the lower part of the side wall of the vehicle body, the vehicle wheel axle is in sliding fit with the interior of the strip hole, the upper end and the lower end of the lower rocking rod are respectively hinged to the lower end of the upper rocking rod and the vehicle wheel axle, the upper end of the upper rocking rod is hinged to the vehicle body, and a connecting rod is hinged between the middle part of the crank and the hinging part of the upper rocking rod and the lower rocking rod. When the upper rocking rod and the lower rocking rod are coaxially arranged, the crank and a connecting rod are also coaxially arranged. The simple manual carrying vehicle has the beneficial effects that the structure is simple, and the implementation is easy.
Description
Technical field
The present invention relates to a kind of handbarrow.
Background technology
Manual transport trolley, needs the logistics haulage equipment manually working the effect of transporting goods, is the easiest, the most effective, modal loader and porter's tool in pallet traffic instrument, is widely used in logistics, warehouse, factory etc.Be mainly used in carrying all kinds of mechanical machine or other weights, can coordinate jack, the hand lifting gears such as top of carrying on the arm use together, reduce labour intensity, raise the efficiency.Pallet fork below its car body inserts in the pallet hole of goods bottom by transport trolley in use, realizes hoisting of pallet cargo and declines, and pulled transport operation by manpower by manpower or hydraulic efficiency pressure system.But existing instrument increasingly complex, the manufacturing cost of whole transport trolley promotes gradually, the difficulty also corresponding increase of maintenance.
Summary of the invention
The invention is intended to provide a kind of simply constructed manual simplified transport trolley, with low cost and easy access.
Manual simplified transport trolley in this programme, comprise car body and axletree, rocking bar, lower rocking bar and crank is hinged with outside the sidewall of car body, car body lower sidewall is provided with vertical cylindrical void, axletree is slidably fitted in cylindrical void, the two ends up and down of lower rocking bar respectively with upper rocking bar lower end and axletree hinged, upper rocking bar upper end thereof is on car body, connecting rod is hinged with, crank and connecting rod also conllinear when upper rocking bar and lower rocking bar conllinear between the middle part of crank and the articulated section of upper and lower rocking bar.
When on car during unloaded goods, can connecting rod horizontal direction be moved driving crank rotation, the angle between rocking bar, lower rocking bar is made to diminish (when upper rocking bar, lower rocking bar conllinear, angle is therebetween considered as 180 °), because the hinge of upper rocking bar upper end and car body is fixed, the lower end of following rocking bar order about axletree in cylindrical void on move, after axletree is worked in coordination with wheel is moved, vehicle bottom reduces gradually, so that toward lade on car body.After lade completes, pull crank, make crank and connecting rod conllinear, now go up rocking bar and lower rocking bar also conllinear, axletree and wheel move down and support car body, and now quadric linkage is in dead center position, whole connecting rod mechanism is in stabilized conditions, can promote car body, relies on wheel rolling to move ahead.This programme simple structure, easy to implement, with low cost and easy access.
Further, crank and the connecting rod also horizontal conllinear when upper rocking bar and lower rocking bar vertical colli piear.Whole mechanism is comparatively stable.
Further, car body is provided with draw-in groove and the bayonet lock that crank can be fixed on level attitude.Crank is fixed on dead center position, makes dolly more stable at motoring condition.
Further, the free end of crank is provided with handle.When crank level is fixed, can with the double effect doing handle of crank.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that in the embodiment of the present invention, dolly is in landing state.
Fig. 2 is the schematic diagram that in the embodiment of the present invention, dolly is in walking states.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: sidewall 1, upper rocking bar 2, lower rocking bar 3, axletree 4, wheel 5, connecting rod 6, crank 7, draw-in groove 8, pin 9.
Embodiment is substantially as shown in drawings: the dolly in Fig. 1 is in the state of handling goods, and the both sides sidewall of car body is respectively one block of square plate, and on biside plate, the structure of each parts is specular.The two ends up and down of lower rocking bar respectively with upper rocking bar lower end and axletree hinged, axletree is slidably fitted in cylindrical void, upper rocking bar upper end thereof is on the fixing hinge of car body, upper rocking bar, lower rocking bar angle are 130 °, now axletree is positioned at position top on cylindrical void, the lower edge of wheel is also higher than vehicle bottom, and the bottom of car body falls on the ground.The sidewall of car body is also hinged with crank, and the middle part of crank is connected by connecting rod with upper rocking bar and lower rocking bar, and the two ends of connecting rod are hinged.
Dolly in Fig. 2 is in the state that can move ahead according to wheel rolling, reach this state, need to pull crank when dolly is in the state of handling goods, crank and connecting rod is made to be in the state of horizontal conllinear, because the length and location of each bar is through prior design calculation, now go up the state that rocking bar and lower rocking bar are also necessarily in vertical conllinear.Now when angle of obliquity is 90 °, be zero to the moment of torsion of crank, mean that now connecting rod can not swing by driving crank, mechanism is in this position becomes dead point.Dolly can promote to move ahead under this kind of state.
And in order to ensure the stable of whole state, car body is also provided with draw-in groove, the bottom of draw-in groove is closed, upper opening and aim at crank, crank cannot continue to rotate counterclockwise downwards after entering draw-in groove by opening, be the pin that top is also provided with pin-and-hole and coupling at draw-in groove, pin can be put into after crank enters draw-in groove and exit to stop crank.The free end of crank is designed to hand handle, be convenient to when crank level is fixed personnel hold crank promote dolly move ahead.
When needing the trolley moved ahead to move down unloading, cancel pin to the constraint of crank, apply external force rotating crank, rocking bar and lower rocking bar can be driven to swing, and finally make wheel moves, car body falls.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in specification sheets etc. record the content that may be used for explaining claim.
