Abstract
The utility model discloses a loading and unloading car, belonging to the technical field of object transportation. The technical problem to be solved is to provide the loading and unloading car which facilitates transportation and unloading and is low in cost, to improve the working efficiency. The technical scheme is that a lifting frame is hinged on one end of a rack, wherein the middle part of the lifting frame is hinged with a piston rod of a lifting oil cylinder; a cylinder body of the lifting oil cylinder is hinged on the bottom part of the rack; two groups of first rollers are arranged in parallel on the lifting frame, and the top parts of the first rollers are higher than the upper surface of the lifting frame; two guide slots are arranged in parallel below the rack; a plurality of long through holes are arranged on the rack above each guide slot; a second roller is arranged in each long through hole; the upper surfaces of two shift forks of a control fork are wave-shaped, and the two shift forks are respectively arranged in the two guide slots; and a control oil cylinder body of the control fork is fixed below the rack. The loading and unloading car provided by the utility model is used for transporting heavy objects.
Description
Technical field
A kind of loading and unloading dolly of the utility model belongs to object transportation technology field.
Background technology
At present, object transportation adopts the flat trucks transportation, needs the people that object is lifted the upper flat plate car, shifts the destination onto, carries off again, and when the transportation thing is very heavy thing, will bring the inconvenience in the work to the staff, wastes time and energy again.And in transportation; Sometimes can run into also that the flat truck car body damages, wheel does not change, off-axis, fall abnormal condition such as wheel; The reparation of flat truck is wasted time and energy and is inconvenient; Just the methods of changing flat truck that adopt have so just reduced work efficiency and have strengthened cost again, for the staff brings inconvenience more.
The utility model content
The utility model overcomes the deficiency that prior art exists, and technical matters to be solved provides a kind ofly to be convenient to transportation, unloading, to load and unload dolly cheaply, has improved work efficiency.
In order to solve the problems of the technologies described above; The technical scheme that is adopted is: a kind of loading and unloading dolly, comprise wheel, frame and alighting gear, and the frame below is equipped with a plurality of wheels; One end of frame is hinged with alighting gear; The alighting gear middle part is hinged with the piston rod of lift ram, and the cylinder body of lift ram is hinged on the frame bottom, and the top that is set side by side with two group of first roller and first roller on the alighting gear is higher than the upper surface of alighting gear;
The frame parallel beneath is equipped with two guide grooves; All have a plurality of microscler through holes on the frame of each guide groove top; One second roller all is installed in each microscler through hole; Two shift fork upper surfaces of control yoke are waveform and are installed in respectively in described two guide grooves that the control cylinder block of control yoke is fixed on the frame below.
The supporting of slide roller straight line needle roller is installed between the shift fork of described control yoke and the guide groove.
The utility model compared with prior art has following beneficial effect.
1, the utility model stretches out the rising of promotion second roller with the control yoke of frame below when unloading; The alighting gear of frame front end descends and forms the slope; And first roller on the alighting gear, the purpose of friction force made unloading more convenient when the roller rolling reduced to unload when having realized the object unloading; And not fragile, reduced cost.
2, the utility model is equipped with the supporting of slide roller straight line needle roller between the shift fork of control yoke and guide groove, and the resistance when having reduced mutual motion makes equipment operation more smooth and easy.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the birds-eye view of Fig. 1.
Fig. 3 is the scheme of installation of shift fork, guide groove and frame.
Fig. 4 is the structural representation of control yoke.
Fig. 5 is the mounting structure scheme drawing of the control yoke and second roller.
Among the figure: 1 is wheel, and 2 is frame, and 3 is alighting gear, and 4 is lift ram, and 5 is first roller, and 6 is guide groove, and 7 is second roller, and 8 is control yoke, and 9 is shift fork, and 10 are the control oil cylinder, and 11 is the supporting of slide roller straight line needle roller.
The specific embodiment
Shown in Fig. 1-5; A kind of loading and unloading dolly of the utility model comprises wheel 1, frame 2 and alighting gear 3, and frame 2 belows are equipped with a plurality of wheels 1; One end of frame 2 is hinged with alighting gear 3; The piston rod of alighting gear 3 middle parts and lift ram 4 is hinged, and the cylinder body of lift ram 4 is hinged on frame 2 bottoms, and the top that is set side by side with two group of first roller 5 and first roller 5 on the alighting gear 3 is higher than the upper surface of alighting gear 3;
The frame parallel beneath is equipped with two guide grooves 6; All have a plurality of microscler through holes on the frame 2 of each guide groove 6 top; One second roller 7 all is installed in each microscler through hole; Two shift fork 9 upper surfaces of control yoke 8 are waveform and are installed in respectively in described two guide grooves 6 that control oil cylinder 10 cylinder bodies of control yoke 8 are fixed on frame 2 belows.
Slide roller straight line needle roller supporting 11 is installed between the shift fork 9 of described control yoke 8 and the guide groove 6.
Working process
After arriving the destination, lift ram 4 control alighting gears 3 descend and form the slope, control oil cylinder 10 piston rods pulling control yoke 8, and the waveform structure on the control yoke 8 makes second roller 7 rise to plane on the frame 2, the object of can easily leaving behind.
Combine accompanying drawing that the embodiment of the utility model has been done detailed description above; But the utility model is not limited to the foregoing description; In the ken that those of ordinary skills possessed, can also under the prerequisite that does not break away from the utility model aim, make various variations.
