[0015] The specific implementation of the utility model is further described in detail below through the description of embodiments in conjunction with the accompanying drawings.
[0016] The grass and bark used in the production of rice paper need to be spread out on the hillside for drying, and the drying operation area usually extends in the horizontal direction of the hillside. When a monorail transport vehicle is used to transport the grass and bark, in order to reduce the labor intensity of the workers' transportation operations and facilitate the transportation of items in the laterally extended operation area, the monorail transport track for the transport vehicle should be deep into the operation area. Figure 1As shown, the monorail transport track includes a fixed track 10 and a reversing track 20, wherein the fixed track 10 includes a main track 10a, a first sub-track 10b, and a second sub-track 10c arranged at intervals, wherein one end of the main track 10a extends toward the grass and bark processing site, and the other end of the main track 10a is connected to the first sub-track 10b or the second sub-track 10c through the reversing track 20. The first sub-track 10b and the second sub-track 10c extend to the same side of the main track 10a away from the track sections of the main track 10a, and divide the drying operation area on the hillside into several operation areas. It is defined that the main track 10a and the first sub-track 10b are enclosed to form a first operation area 1, and the first sub-track 10b and the second sub-track 10c are enclosed to form a second operation area 2. Furthermore, the area above the second sub-track 10c can be defined as a third operation area 3. In this way, each operation area is arranged adjacent to the transport track, which can effectively shorten the route of the drying operation.
[0017] This embodiment is shown in the attached Figure 3 As shown, teeth 30 are respectively provided at the bottom of the fixed track 10 and the reversing track 20, and the teeth 30 engage with the protruding columns on the running wheels of the transport vehicle. In this way, as long as the rotation of the running wheels is restricted, the transport vehicle can move stably on the slope section and can also ensure stable and reliable parking of the transport vehicle.
[0018] In order to realize the change of the transport track, the reversing track 20 is detachably connected to the fixed track 10 in this embodiment. In this embodiment, the reversing track 20 includes a first end 20a and a second end 20b. In the initial state, when the first end 20a is connected to the main track 10a, the second end 20b is connected to the first branch track 10b, and the tooth 30 is located at the bottom of the track. When changing the transport track, in order to maintain the posture of the tooth 30 being located at the bottom of the track, the two ends of the reversing track 20 need to be turned so that the second end 20b is connected to the main track 10a and the first end 20a is connected to the second branch track 10c.
[0019] To achieve the above-mentioned track change method, the details are as follows: Figure 2 , 3 As shown, the center line of the bar-shaped reversing track 20 is a curve. If the angle between the tangent directions at both ends of the reversing track 20 is α, the angle between the extension direction / tangent direction of the end of the main track 10a and the extension direction / tangent direction of the first sub-track 10b is β, and the angle between the extension direction / tangent direction of the end of the main track 10a and the extension direction / tangent direction of the second sub-track 10c is γ, it is necessary to set α=β=γ to achieve a reliable connection between the reversing track 20 and the two sub-tracks. It should be noted that the attached Figure 2In the embodiment shown, the end sections of the main rail 10a, the first sub-rail 10b, and the second sub-rail 10c are all straight rail sections, β is the angle between the extension directions of the main rail 10a and the first sub-rail 10b, and γ is the angle between the extension directions of the main rail 10a and the second sub-rail 10c. In other embodiments, if the end section of the fixed rail 10 is a curved rail section, the tangential direction of the end of the rail should be used to determine the angle.
[0020] In this embodiment, one side of the fixed track 10 is fixed with a connector, and the other side is left vacant to avoid the running mechanism of the transport vehicle. The running mechanism of the transport vehicle includes a running wheel meshing with the teeth 30 at the bottom of the track and a positioning wheel rolling with the upper surface of the track. The running wheel and the positioning wheel are respectively hingedly connected to the vertically arranged connecting plate. In specific implementation, one side of the fixed track 10 is left vacant to avoid the aforementioned connecting plate, so as to prevent the components attached to the side of the track from interfering with the connecting plate and thus preventing the running mechanism from passing. Figure 6 As shown, the connector and the vertical pole 40 arranged beside the fixed track 10 form a detachable limit fit, and the bottom of the vertical pole 40 is fixedly connected to the ground, so that the fixed track 10 is installed overhead at a preset position. The fixed track 10 is arranged at a distance from the ground, which can effectively prevent rainwater from corroding the track or grass and trees growing on the ground from blocking the track.
[0021] The connecting member includes a first connecting member 12. Figure 6 As shown, the first connecting member 12 includes a tube 121, which is sleeved on the rod body of the vertical rod 40 to limit the relative displacement of the two in the radial direction of the vertical rod 40, and then tightened with screws to limit the displacement of the two in the axial direction of the vertical rod 40, so as to achieve a limited connection between the two. The tube wall of the tube 121 adjacent to the track body first extends along its tangential direction to form a connecting plate 122, and the connecting plate 122 is provided with a sleeve 123 at the cantilevered plate end adjacent to the plate surface of the track body. The sleeve 123 is connected to the track body, so that the track body can be installed. In this embodiment, the sleeve 123 is welded to the track body. In other embodiments, other fixed connection methods can also be used, and screws can also be used to penetrate the sleeve 123 and threadedly connect it to the fixed track body 11.
[0022] The connecting member includes a second connecting member 14, as shown in the attached Figure 6 As shown, the second connecting member 14 includes a cover plate 141 extending outward from the side wall of the track body, and the cover plate 141 is pressed against the upper end of the rod body of the side upright 40 from top to bottom, which can effectively prevent the track body connected to the second connecting member 14 from moving downward. In order to further limit the displacement of the track body in the horizontal plane, in this embodiment, a pin with a pin core arranged perpendicular to its plate surface is provided at the overhanging end of the cover plate 141, and the pin is inserted into the tube cavity of the hollow tubular upright 40 to limit the relative displacement of the two in the radial direction of the upright 40.
[0023] The fixed rail 10 can be provided with a first connector 12 or a second connector 14 as required. In this embodiment, the bottom of the reversing rail 20 is suspended in the air, and both ends are connected to the fixed rail 10. In order to ensure the reliability of the rail section where the reversing rail 20 is located and avoid the rail sinking, the end of the fixed rail 10 adjacent to the reversing rail 20 should preferably be provided with a second connector 14.
[0024] For the convenience of connection, the end of the reversing track 20 is plug-connected with the fixed track 10. Figure 3 , 4 As shown in Figures 6 and 7, both ends of the reversing track 20 are provided with outwardly protruding plug tongues 21, and the end of the fixed track 10 is provided with a slot 131 that matches the outer peripheral contour of the plug tongue 21. In order to prevent the reversing track 20 from falling out, the slot 131 in this embodiment is open at the top and end surface, and a support wall 132 is provided at the bottom. The support wall 132 cooperates with the plug tongue 21 to limit the downward displacement of the reversing track 20 relative to the fixed track 10, that is, the support wall 132 can effectively support the plug tongue 21. The upper surface of the support wall 132 supports the plug tongue 21, and the lower surface is connected to the teeth 30, so that the reliable connection between the reversing track 20 and the fixed track 10 can be achieved while ensuring the reliable engagement between the track joint and the running wheel. In order to further prevent the reversing track 20 from being separated from the fixed track 10 during use, a screw can also be used to penetrate the groove wall and the plug tongue 21 of the slot 131 and lock it with a nut provided on the opposite side, that is, the plug tongue 21 of the reversing track 20 is threadedly connected with the slot 131 of the fixed track 10.
[0025] As attached Figure 6 In the illustrated embodiment, the fixed rail 10 includes a fixed rail body 11, which is in the shape of a hollow square tube. The end of the fixed rail body 11 is plugged into the transfer rail 13, and a slot 131 is provided at the end of the transfer rail 13 away from the fixed rail body 11. A first connector 12 is provided at the end of the fixed rail body 11 adjacent to the transfer rail 13, and a second connector 14 is provided at the middle of the length direction of the transfer rail 13. In this way, the transfer rail 13 is used to transitionally connect the reversing rail 20 and the fixed rail body 11, which can facilitate the arrangement of the fixed rail 10 while ensuring the reliability of the connection of the reversing rail 20. In other embodiments, the second connector 14 can also be provided at the end of the fixed rail body 11 adjacent to the transfer rail 13.
[0026] In another embodiment, the transfer track may not be provided, that is, a slot 131 that forms a socket-type fit with the reversing track 20 is provided at the end of the fixed track body 11, and a second connector 14 is provided on the side of the fixed track body 11 adjacent to the slot 131, and the first connector 12 or the second connector 14 can be evenly arranged in the length direction of the fixed track body 11 as required. However, due to certain deviations in the layout path and length of the track during on-site construction, the slot 131 can only be obtained by processing the end of the fixed track body 11 at the construction site, so the processing quality of the slot 131 cannot be guaranteed, so the preferred embodiment of this embodiment connects the end of the fixed track body 11 to the reversing track 20 through the transfer track 13.
