[0021] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1 to 4As shown in the figure, the present invention provides a cargo lifting mechanism for road freight transportation, including a base plate 1 and a lifting machine body 2. The lifting machine body 2 is fixedly connected to the top of the base plate 1. Universal wheels 3 are fixedly connected to the four corners of the lower surface of the base plate 1. A loading plate 4 is placed on the top of the base plate 1. The rear side of the loading plate 4 is fixedly connected to the output end of the lifting machine body 2. A receiving plate 5 is fixedly connected to the top of the rear side of the loading plate 4.

[0023] refer to Figure 3 The receiving plate 5 has a receiving groove 6 inside, and a gear disk 7 is placed inside the receiving groove 6. The axial positions of the front and rear sides of the gear disk 7 are rotatably connected to the receiving groove 6. The left and right sides of the front surface of the gear disk 7 are provided with guide grooves 8, which are all curved. The guide grooves 8 are all placed inside the guide grooves 8, and the sliders 9 are all slidably connected to the inside of the guide grooves 8. The left and right sides of the front surface of the receiving plate 5 are provided with through grooves 10, and the front sides of the sliders 9 are all slidably connected to the inside of the through grooves 10.

[0024] By adopting the above scheme, by setting the guide groove 8 and the through groove 10, the slider 9 can move along a predetermined trajectory when the gear disk 7 rotates, thereby realizing the synchronous adjustment of the limit plate 13 and enhancing the adaptability of the device to goods of different sizes.

[0025] refer to Figure 2 Movable frames 11 are placed on both the left and right sides of the front surface of the receiving plate 5. The front side of the slider 9 is fixedly connected to the rear side of the movable frame 11. The front side of the movable frame 11 is provided with a moving groove 12. Two limiting plates 13 are placed on the front side of the movable frame 11. The rear side of the limiting plates 13 is slidably connected to the inside of the moving groove 12.

[0026] By adopting the above solution, the position of the goods can be limited by setting the limit plate 13, preventing deviation or tipping during the lifting process, thereby improving the safety and stability of the overall operation.

[0027] refer to Figure 3 A rack 14 is placed at the bottom of the gear disk 7. The bottom of the rack 14 is slidably connected to the bottom of the receiving groove 6. The rack 14 is meshed with the gear disk 7. A lead screw 16 is placed at the bottom of the gear disk 7. The left end of the lead screw 16 is rotatably connected to the left side of the receiving groove 6. The right end of the lead screw 16 passes through and extends out of the right side of the receiving plate 5. A motor 15 is fixedly connected to the right side of the receiving plate 5. The right end of the lead screw 16 is fixedly connected to the output end of the motor 15. The rack 14 is threadedly connected to the surface of the lead screw 16.

[0028] By adopting the above solution, the position of the limit plate 13 can be precisely and automatically adjusted by setting the rack 14, the lead screw 16 and the motor 15, ensuring the stable clamping of the goods during the lifting process, and improving the automation level and work efficiency of the equipment operation.

[0029] refer to Figure 4 The limiting plate 13 has grooves 17 inside, and springs 18 are placed inside the grooves 17. The springs 18 are fixedly connected to the surface of the grooves 17. The end of the spring 18 near the slider 9 is fixedly connected to a fixing rod 19. The fixing rod 19 is slidably connected to the inside of the grooves 17. The end of the fixing rod 19 away from the spring 18 passes through and extends out of the surface of the limiting plate 13. The other end of the fixing rod 19 is fixedly connected to a pull rod 20. The end of the pull rod 20 away from the fixing rod 19 passes through and extends out of the surface of the limiting plate 13.

[0030] By adopting the above solution, the fixed rod 19 and spring 18 can be set to quickly lock and release the position of the limit plate 13, which improves the convenience of equipment operation and the stability of the clamping state.

[0031] refer to Figure 2 The limiting plates 13 are provided with a number of fixing holes 21 at equal intervals on the opposite sides, and the fixing holes 21 are used in conjunction with the fixing rods 19.

[0032] By adopting the above solution, by setting a number of fixing holes 21, the limiting plate 13 can be reliably fixed in any adjustable position, which enhances the compatibility of the equipment with goods of different sizes.

[0033] refer to Figure 2 The upper and lower sides of the front surface of the receiving plate 5 are provided with stabilizing grooves 22, and the upper and lower sides of the rear surface of the movable frame 11 are slidably connected to the inside of the stabilizing grooves 22.

[0034] By adopting the above solution, the stabilizing groove 22 is set to ensure the smooth sliding of the moving frame 11 in the horizontal direction, avoiding swaying or tilting caused by uneven force, and further improving the accuracy and safety of the equipment in clamping goods.

[0035] The working principle of this utility model:

[0036] In use, first adjust the position of the two limiting plates 13 according to the size of the goods to be lifted. Pull the fixing rod 19 by the pull rod 20. After the fixing rod 19 moves out of the fixing hole 21, move the limiting plate 13 along the moving groove 12. After the limiting plate 13 moves to the appropriate position, release the pull rod 20. At this time, the spring 18 will cause the fixing rod 19 to insert into the corresponding fixing hole 21, thereby fixing the limiting plate 13. After the limiting plate 13 is adjusted, place the goods on the top of the carrying plate 4, and then start the motor 15. The motor 15 drives the lead screw 16 to rotate, the lead screw 16 drives the rack 14 to move, and the rack 14 drives the gear disk 7 to rotate. Since the slider 9 is slidably connected to the through groove 1, Since the inside of the gear plate 0 is limited, the slider 9 can only move left and right. When the gear plate 7 rotates, the sliders 9 on both sides will move in opposite directions synchronously due to the tilt angle of the guide groove 8. Then the slider 9 drives the moving frame 11 to move, and the moving frame 11 drives the limiting plate 13 to move, thereby limiting and fixing the goods to prevent deviation during the lifting process. Then the main body 2 of the elevator can be used to lift the goods to a suitable height, control the motor 15 to reverse, the lead screw 16 to rotate in the opposite direction, drive the rack 14 to reset, thereby causing the gear plate 7 to rotate in the opposite direction, the slider 9 to retract, the moving frame 11 to drive the limiting plate 13 to return to its original position, and release the limiting state of the goods. Finally, the goods can be removed from the top of the carrying plate 4.

[0037] In summary, the cargo lifting mechanism for road freight transport, through the coordinated use of a base plate 1, lifting machine body 2, casters 3, load-bearing plate 4, receiving plate 5, receiving groove 6, gear disk 7, guide groove 8, slider 9, through groove 10, moving frame 11, moving groove 12, limiting plate 13, rack 14, motor 15, lead screw 16, groove 17, spring 18, fixing rod 19, pull rod 20, fixing hole 21, and stabilizing groove 22, solves the problem that existing equipment often lacks effective self-adaptive limiting function, making it difficult to automatically adjust the clamping position according to the cargo size during lifting, easily leading to cargo deviation or insecure fixing, thus affecting loading and unloading efficiency and safety.
