Technical Field
The invention relates to the technical field of agricultural product transportation equipment, in particular to a non-rigid wheel monorail transport vehicle with a climbing function and a transportation system.
Background
The fruit tree planting area in China mainly focuses on mountainous and hilly lands with complex terrain and large gradient, and the traditional wheel type transport vehicle is difficult to operate in the complex terrain environment, so that the fruit and material are transported by manpower under the constraint of the complex landform environment, the labor intensity is high, the efficiency is low, and the cost is high; in order to improve the transportation efficiency and the mechanization degree of hilly and hilly orchards, the monorail conveyor is produced at the same time. In order to adapt to terrains, a conveyor track usually has various slopes, and in order to realize a climbing function, a traditional single-track conveyor system usually adopts a rack arranged on the track, and a driving gear arranged on a machine head so as to ensure a climbing effect.
For example, ZL201811291968.9 discloses a monorail conveyor head and a monorail conveyor thereof, which rely on the rack arranged on the track and drive the whole conveyor through the gear of the conveyor head, and this driving manner of the rack and the gear can ensure that the conveyor has sufficient traction force when going up the slope, but the manufacturing and building cost of the whole track is high, and the maintenance method of the track is complicated. For another example, in the track structures of two monorail conveyors disclosed in zl201820659444.x and zl201720051093.x, the racks are replaced by equally spaced holes formed in the tracks, however, the hole forming cost and the maintenance difficulty of the tracks in the form are still constant, the structure driven by the gear of the machine head is reserved, and the machine head structure of the whole conveyor is complex and not easy to maintain.

A monorail transportation system comprises a monorail transportation vehicle and a track, wherein the monorail transportation vehicle is the non-rigid wheel monorail transportation vehicle, the track is a square tube track with a rectangular cross section, and the length and width of the cross section of the square tube track are both 30 ~ 80 mm.
Because the cross section of the common track of the monorail transport vehicle is a square tube with the thickness of 50mm, in the embodiment, the front and rear driving wheels 211 are adopted, and the arrangement form of four wheels is totally adopted, so that enough friction force can be provided, the whole transport vehicle has the capacity of loading 200 ~ 300kg and climbing 45 degrees, and the form of the front and rear driving wheels 211 can ensure that the front and rear vehicle bodies still have strong driving capability when any one driving wheel 211 is damaged or a driving motor fails.
Example 2:
the difference from the above embodiment 1 is that, according to fig. 4, the transportation vehicle body 1 includes two or more hopper vehicle bodies 11 movably connected to each other, and the hopper vehicle bodies 11 are connected to each other by a rail hinge 4 so that the joint of the hopper vehicle bodies 11 can be attached to a rail.

Example 3:
the difference from the above embodiment 1 or 2 is that the driving mechanism 2 includes two sets of electric driving wheel modules 21 respectively disposed at the front and rear ends of the transportation vehicle body 1, each set of electric driving wheel modules 21 includes at least two driving wheels 211 and at least two driving motors 212, and the whole transportation vehicle is provided with more than five driving wheels 211, the driving wheels 211 are arranged along the length direction of the track, and the bottoms of the driving wheels 211 are in contact with the track.
The vehicle body with the structure of the embodiment has stronger driving capability at a linear track and stronger climbing capability on a steeper linear slope due to more driving wheels 211; the disadvantage is that in the arc ascending track section, more than two driving wheels 211 which are arranged in a straight line only have two heads and two tails which are contacted with the track, and the driving wheel 211 in the middle can not be attached to the surface of the track, so the climbing effect in the arc track section is not ideal.
Example 4:
the difference from the above embodiment 1, 2 or 3 lies in that the track positioning mechanism 3 is directly connected to the transportation vehicle body 1 through the positioning wheel fixing frame 33, and it is easy to think that the function of adjusting the distance between the track and the center position of the driving wheel 211 can still be realized by arranging the guide rod in the transportation vehicle body 1 to match with the guide rod insertion hole of the positioning wheel fixing frame 33.
Example 5:
different from the above embodiment 1, 2 or 3, the track positioning mechanism 3 is fixedly connected to the transportation vehicle body 1 or the wheel carrier 213, in this embodiment, due to the fixed connection form adopted, the distance between the transportation vehicle body 1 and the track is not changeable, however, since the track clamping grooves on the outer rings of the upper positioning wheel 31 and the lower positioning wheel 32 have a certain depth, and the horizontal distance between the upper positioning wheel 31 and the lower positioning wheel 32 itself is slightly larger than the thickness of the track, the driving wheel 211 still has a deformation space under heavy pressure, and the whole transportation vehicle still has a certain climbing capability.
