Abstract
The invention relates to a loading and unloading trolley which belongs to the technical field of object transportation and aims to provide the loading and unloading trolley which is convenient for transportation and unloading, low in cost and capable of improving the working efficiency. The adopted technical scheme is described as follows: a lifting frame is hinged at one end of a rack; the middle part of the lifting frame is hinged with a piston rod of a lift cylinder; the cylinder body of the lift cylinder is hinged at the bottom part of the rack; two side-by-side first rollers are arranged on the lifting frame; tops of the first rollers are above the upper surface of the lifting frame; two parallel guide grooves are arranged below the rack; a plurality of long through holes are arranged in the rack above each guide groove; a second roller is arranged in each long through hole; upper surfaces of two shift forks of a control fork are shaped like waves; the two shift forks are respectively arranged in the two guide grooves; and a control cylinder body of the control fork is fixed below the rack. The loading and unloading trolley disclosed by the invention is used for the transportation of heavyweight objects.
Description
Technical field
The present invention loads and unloads dolly, 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.
Summary of the invention
The present invention 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: the 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 present invention compared with prior art has following beneficial effect.
1, the present invention 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 present invention 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 present invention is described further.
Fig. 1 is a structural representation of the present invention.
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. 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; The present invention loads and unloads dolly, 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 embodiments of the invention have been done detailed description above, but the present invention 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 aim of the present invention, makes various variations.
