Detailed Implementation
[0026] The present invention will now be described in further detail with reference to the accompanying drawings.
[0027] like Figures 1 to 9 As shown below, the structure and function of a freight protective forklift will be described in detail.
[0028] A cargo protective forklift includes two movable supports 11, two lifting supports 31 rotatably connected between the two movable supports 11, a cargo support mechanism 4 connected to each of the two lifting supports 31, a release mechanism 5 fixedly connected to each of the two cargo support mechanisms 4, and a side protection mechanism 6 connected to each of the two movable supports 11.
[0029] When using, such as Figure 1 As shown, the goods to be transported are initially clamped by two side guards 6, and the bottom of the goods is raised by two side guards 6 to a certain height, so that the supporting mechanism 4 can be inserted into the bottom of the goods. The goods are moved by the supporting mechanism 4 and the two side guards 6 working together. The goods are placed on the supporting mechanism 4, and the supporting mechanism 4 lifts the goods. The two side guards 6 provide auxiliary clamping and fixing of the sides of the goods. The release mechanism 5 provides auxiliary support for the top and rear of the goods, thereby achieving multi-directional fixation of the goods and thus achieving safe and stable transportation of the goods.
[0030] Furthermore, such as Figure 4 As shown, a rotating seat 13 is fixedly connected to the movable support 11, and movable wheels 12 are rotatably connected to both the front and rear ends of the movable support 11. A lead screw I 15 is rotatably connected to the movable support 11.
[0031] Two connecting brackets 14 are fixedly connected between the two movable brackets 11, two sliding columns 16 are fixedly connected between the two connecting brackets 14, and two lead screws II 17 are rotatably connected between the two connecting brackets 14.
[0032] The movable bracket 11 is fixedly connected to a power mechanism I that drives the lead screw I 15 to rotate, and the connecting bracket 14 is fixedly connected to a power mechanism II that drives the lead screw II 17 to rotate.
[0033] To facilitate the movement of the movable support 11, the movable wheel 12 is driven to rotate. A power mechanism IV for driving the movable wheel 12 to rotate can be fixedly connected to the movable support 11. The power mechanism IV is preferably a servo motor. The output shaft of the power mechanism IV drives the movable wheel 12 to rotate. The movable wheel 12 contacts the ground. When the output shaft of the power mechanism IV starts to rotate, the power mechanism IV drives the movable wheel 12 to rotate, so that the movable wheel 12 drives the movable support 11 to move. This allows the movable support 11 to move to the side of the goods. During the lifting of the goods, the movement of the movable support 11 can also drive the support mechanism 4 to move, so that the support mechanism 4 is inserted into the bottom of the goods.
[0034] Furthermore, such as Figure 6 As shown, in order to prevent goods from falling off during transportation, and also to enable the lifting mechanism 4 to stably lift and transport goods with irregular bottom shapes.
[0035] Each of the two sliding columns 16 is slidably connected to a pull seat 21. The two pull seats 21 are respectively connected to two lead screws II 17 by threads. Each of the two pull seats 21 is hinged to a connecting rod 22. The two connecting rods 22 are respectively hinged to two lifting brackets 31.
[0036] A rack 33 is fixedly connected to the lifting bracket 31, and a rotating shaft 32 is fixedly connected to the bottom of the lifting bracket 31. The rotating shaft 32 is rotatably connected to the rotating seat 13.
[0037] The supporting mechanism 4 includes a movable seat I 41, which is slidably connected to the lifting bracket 31. A supporting plate 42 is fixedly connected to the bottom of the movable seat I 41. A gear 43 is rotatably connected to the movable seat I 41, and the gear 43 and the rack 33 mesh and drive each other.
[0038] The movable seat I 41 is fixedly connected to a power mechanism III that rotates by a drive gear 43;
[0039] When in use, the power mechanism III is started. The power mechanism III is preferably a servo motor. The output shaft of the power mechanism III drives the drive gear 43 to rotate. The drive gear 43 meshes with the rack 33. During the rotation of the drive gear 43, the drive gear 43 drives the moving seat I 41 to move up and down on the lifting bracket 31. The moving seat I 41 drives the pallet 42 to move up and down, so that the pallet 42 is lowered to a certain height, so that the pallet 42 can be inserted into the bottom of the goods, and after being inserted into the bottom of the goods, the goods can be lifted.
[0040] In order for the pallet 42 to lift the bottom of irregular goods, the two pallets 42 are controlled independently, so that the two pallets 42 can be raised and lowered to different heights, thereby lifting the bottom of the goods at different heights.
[0041] Furthermore, during the handling of goods, in order to prevent the goods from falling off the front side of the pallet 42 when the speed of movement changes, the power mechanism II is activated. The power mechanism II is preferably a servo motor. The output shaft of the power mechanism II drives the lead screw II 17 to rotate. When the lead screw II 17 rotates, it drives the pulling seat 21 to move through the thread, so that the pulling seat 21 slides on the sliding column 16. During the movement of the pulling seat 21, the connecting rod 22 is pulled to move. The connecting rod 22 pulls the lifting bracket 31 to move, so that the upper end of the lifting bracket 31 is tilted backward, thereby raising the front end of the pallet 42, causing the goods to tilt to a certain extent, so that the center of gravity of the goods is placed at the rear, preventing the goods from falling off the front side of the pallet 42 when the speed of movement changes.
[0042] Furthermore, in order for the pallet 42 to lift the bottom of irregular goods, the two pallets 42 are controlled independently. The two pallets 42 can be tilted to different angles, thereby lifting the inclined surface of the bottom of the goods at different positions.
[0043] Furthermore, to provide additional securing to the top and front of the cargo, such as... Figure 7 As shown;
[0044] The release mechanism 5 includes a telescopic mechanism I 51, which is fixedly connected to the movable seat I 41. A release rod 52 is fixedly connected to the telescopic end of the telescopic mechanism I 51. A release hook 53 is hinged to the end of the release rod 52. A torsion spring is fixedly connected between the release hook 53 and the release rod 52. A plurality of release grooves 54 are provided on the inner side of the lower end of the release hook 53.
[0045] After the goods are placed on the two pallets 42, the telescopic mechanism I51 is activated. The telescopic mechanism I51 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism I51 drives the release rod 52 to move downward. The release rod 52 drives the release hook 53 to move downward, so that the lower end of the rear side of the release hook 53 contacts the top of the goods. The telescopic end of the telescopic mechanism I51 continues to drive the release rod 52 to move downward, so that the top of the goods lifts the lower end of the rear side of the release hook 53. The release hook 53 overcomes the force of the torsion spring, so that the outer side of the front end of the release hook 53 moves downward, so that the lower side of the front end of the release hook 53 hooks onto the front side of the goods. In this way, the upper end and the front side of the goods are fixed at the same time.
[0046] Furthermore, it should be noted that the length of the goods here is greater than the length formed by the combination of the release hook 53 and the release rod 52 when the front end of the release hook 53 is set horizontally, so as to ensure that the release groove 54 can contact the side of the goods, thereby ensuring the stability of the goods being fixed.
[0047] Furthermore, such as Figure 8 As shown, this is done to lift the goods to a certain extent during placement and to provide stable support for the sides of the goods during transportation.
[0048] The side protection mechanism 6 includes a movable seat II 61, which is slidably connected to the movable bracket 11. The movable seat II 61 is threadedly connected to the lead screw I 15. A telescopic mechanism II 62 is fixedly connected to the movable seat II 61. A telescopic mechanism III 63 is fixedly connected to the telescopic end of the telescopic mechanism II 62. A side protection plate 64 is fixedly connected to the telescopic end of the telescopic mechanism III 63.
[0049] Start the power mechanism I, preferably a servo motor. The output shaft of the power mechanism I drives the lead screw I15 to rotate. When the lead screw I15 rotates, it drives the moving seat II61 to move through the thread. The moving seat II61 drives the telescopic mechanism II62 to move. The telescopic mechanism II62 drives the telescopic mechanism III63 to move. The telescopic mechanism III63 drives the side guard plate 64 to move, thereby adjusting the front and rear position of the side guard plate 64.
[0050] Start telescopic mechanism II 62 and telescopic mechanism III 63. Telescopic mechanism II 62 and telescopic mechanism III 63 can be hydraulic cylinders or electric push rods. The telescopic end of telescopic mechanism II 62 drives telescopic mechanism III 63 to perform lifting and lowering movements. Telescopic mechanism III 63 drives side guard plate 64 to perform lifting and lowering movements, thereby adjusting the height of side guard plate 64.
[0051] The telescopic end of the telescopic mechanism Ⅲ63 drives the side guard plate 64 to move laterally, thereby adjusting the relative distance between the two side guard plates 64 on both sides, so that the two side guard plates 64 can clamp goods of different widths. After the two side guard plates 64 clamp the goods, the telescopic mechanism Ⅱ62 is activated to lift the goods to a certain height. Then, by moving the positions of the two side guard plates 64 and the two support plates 42, the support plates 42 are inserted into the bottom of the goods, completing the lifting and placement of the goods.
[0052] Furthermore, during cargo transportation, the two side guards 64 are always in contact with the sides of the cargo, thereby supporting the sides of the cargo and preventing the cargo from tilting to the side.
