[0023] Referring Figures 1 - 3 as shown, an embodiment of the present utility model is:
[0024] A programmable traveling transportation system includes a conveying roller bed 1, on which a flat sled 2 is placed. On both sides of the upper end of the flat sled 2, there are limit rods 3. At the upper ends of the limit rods 3, there is a cross arm 4. On the cross arm 4, there are hanging ears 5. Above the conveying roller bed 1, there is an upright frame 6. On the upright frame 6, there is a moving frame 7. On the upper cantilever of the moving frame 7, a hoist 8 is installed. The movable end of the hoist 8 hangs a movable frame 9. At the lower end of the movable frame 9, there is a lifting lug 10 adapted to the hanging ear 5.
[0025] Specifically, the conveying roller bed 1 is arranged between the loading and unloading stations. Before loading, the moving frame with the lifting device stops in advance at the loading position. When the flat skid runs to the specified position, the hoist 8 lifts the flat skid through the movable frame, thereby lifting the workpiece to achieve loading. The corresponding operation is opposite during unloading, which will not be elaborated here. A roller bed is used to connect between the loading and unloading positions. The flat skid can run on this roller bed to achieve the purpose of automatic loading, which improves the production efficiency compared with the previous traditional loading and unloading methods. At the same time, the flat skid can be recycled reciprocally on the conveying roller bed. After setting the limiting rod 3, multiple workpieces can be stacked, and the number of carriers is also reduced to a certain extent, so the cost is also reduced to a certain extent.
[0026] Furthermore, to ensure the stability of the up and down movement of the movable frame 9 and ensure that the lifting lug 10 can cooperate more accurately with the hanging lug 5, a limiting guide rail 11 adapted to the movable frame 9 is provided at the lower end of the moving frame 7, and the limiting guide rail 11 is connected to the moving frame 7 through a first stay cable 12.
[0027] Correspondingly, to ensure the connection strength between the flat skid 2 and the limiting rod 3 and the position of the workpiece after loading is centered and stable, the cross arm 4 and the limiting rod 3 are connected through a second stay cable 13, and an anti-collision guiding member is threadedly connected to the limiting rod 3.
[0028] A groove 14 for workpiece positioning is provided on the flat skid 2.
[0029] Specifically, the anti-collision guiding member includes an adjusting screw 15, a U-shaped guiding plate 16, and an adjusting rod 17. The adjusting screw 15 is threadedly penetrated through the limiting rod 3. One end of the adjusting screw 15 is rotatably connected to the bottom of the groove of the U-shaped guiding plate 16, and the other end of the adjusting screw 15 is connected to the adjusting rod 17. Guide surfaces 18 are symmetrically provided on the outer side of the bottom plate of the U-shaped guiding plate 16, and the groove width of the U-shaped guiding plate 16 is adapted to the width of the limiting rod 3.
[0030] The lowermost workpiece can be positioned through the groove 14. When stacking the upper layer of workpieces, the U-shaped guiding plate 16 can effectively prevent the workpiece from colliding with the limiting rod 3, and the guide surface 18 can center the workpiece to ensure that the hanging lug 5 can accurately cooperate with the lifting lug 10 during hoisting. The structure of the U-shaped guiding plate can protect the limiting plate, and at the same time, by using the limiting function of the limiting rod 3, the horizontal movement of the U-shaped guiding plate 16 is ensured during the process of pushing the adjusting screw 15.
[0031] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
