Description

Technical Field

[0001] This utility model relates to the field of loading and lifting technology, and in particular to a cargo transportation loading and lifting device. Background Technology

[0002] A cargo loading and lifting device is a piece of equipment used to lift cargo from a lower position to a higher position, thereby simplifying the loading process, improving loading efficiency, and reducing manual labor intensity.

[0003] Existing cargo loading and lifting devices, when adapting to vehicles of different heights, tend to tilt because the platform for placing goods has a fixed angle. This can easily cause the platform to tilt during the lifting process, which not only reduces loading efficiency but may also cause goods to fall and be damaged.

[0004] Therefore, this utility model proposes a cargo transportation loading and lifting device. Utility Model Content

[0005] The purpose of this utility model is to provide a cargo transportation loading and lifting device to solve the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cargo transport loading and lifting device includes a bottom support frame. Four sets of movable wheels are fixedly connected to the bottom end of the bottom support frame. The four sets of movable wheels are arranged in a square four-corner array. The bottom support frame is triangular. Two sets of bottom extension plates are fixedly connected to the inclined surface of the bottom support frame. A lifting device is attached to the top of the two sets of bottom extension plates. An angle adjustment mechanism is provided on the opposite side of the lifting device.

[0008] Furthermore, the angle adjustment mechanism includes two sets of lifting and moving blocks. The top of each set of lifting and moving blocks is fixedly connected to an extension hinge block one. The top of the extension hinge block one is hinged to an extension hinge block two. The top of the extension hinge block two is fixedly connected to a lifting plate. Several sets of circular holes are opened on both sides of the lifting plate. The circular holes are arranged in a linear array. A limit block is movably sleeved inside one set of the circular holes. One end of a spring is fixedly connected to the side of the limit block. The other end of the spring is fixedly connected to the inner wall of the lifting and moving block. An adjustment lever is fixedly connected to the top of the limit block. The outer wall of the adjustment lever is slidably sleeved with the lifting and moving block.

[0009] Furthermore, a support crossbar is attached to the bottom end of the lifting plate, and both ends of the support crossbar are fixedly connected to the lifting moving block.

[0010] Furthermore, the lifting device includes two sets of side baffles, the bottom ends of both sets of side baffles are fixedly connected to the bottom extension plate, and both ends of the side baffles are fixedly connected to connecting plates. A motor is fixedly connected to the outer wall of one set of connecting plates, and a threaded rod is fixedly connected to the output end of the motor. One set of lifting moving blocks is threadedly connected to the outer wall of the threaded rod.

[0011] Furthermore, the outer wall of the threaded rod is movably sleeved inside two sets of connecting plates, and guide slide rods are fixedly sleeved inside the other two sets of connecting plates. The outer wall of the guide slide rod is slidably sleeved with another set of lifting moving blocks.

[0012] Furthermore, both sets of bottom extension plates are fixedly connected to a hanging block at their bottom ends, and the two sets of hanging blocks are at the same height.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. By pulling the adjusting levers on both sides outward, the limiting block fixedly connected to the bottom of the adjusting lever moves into the interior of the lifting moving block, thus disengaging the surface of the lifting moving block from the limiting block. This allows for adjustment of the angle of the lifting plate on the support crossbar, achieving tilt adjustment of the lifting device. After adjusting to the desired angle, the pushing force on the adjusting lever is released. Under the influence of the spring's elastic potential energy, the limiting block is pushed to re-engage with the lifting plate, locking the angle between the lifting moving block and the lifting plate and maintaining it fixed. By flexibly adjusting the angle of the loading platform, it can be ensured that the goods remain horizontal during the lifting process, preventing goods from slipping or tipping over due to tilting, thereby reducing the occurrence of goods damage and safety accidents. The height of the cargo compartment of different transport vehicles may vary. The adjustable-angle loading platform can be flexibly adjusted according to the vehicle height to ensure that the goods can be placed stably in the cargo compartment. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figures 1 to 4 As shown, the cargo transportation loading and lifting device provided by this utility model includes a bottom support frame 1. Four sets of movable wheels 5 are fixedly connected to the bottom end of the bottom support frame 1. The four sets of movable wheels 5 are arranged in a square four-corner array. The bottom support frame 1 is triangular. Two sets of bottom extension plates 3 are fixedly connected to the inclined surface of the bottom support frame 1. Lifting devices are attached to the top of the two sets of bottom extension plates 3. An angle adjustment mechanism is provided on the opposite side of the lifting device.

[0024] The angle adjustment mechanism includes two sets of lifting moving blocks 8. The top of each set of lifting moving blocks 8 is fixedly connected to an extension hinge block 12. The top of the extension hinge block 12 is hinged to an extension hinge block 2 13. The top of the extension hinge block 2 13 is fixedly connected to a lifting plate 11. Several sets of circular holes are opened on both sides of the lifting plate 11. The circular holes are arranged in a linear array. A limit block 14 is movably sleeved inside one set of circular holes. One end of a spring 16 is fixedly connected to the side of the limit block 14. The other end of the spring 16 is fixedly connected to the inner wall of the lifting moving block 8. An adjustment lever 17 is fixedly connected to the top of the limit block 14. The outer wall of the adjustment lever 17 is slidably sleeved with the lifting moving block 8.

[0025] In use, pull the adjusting levers 17 on both sides to move them outward, so that the limiting block 14 fixedly connected to the bottom of the adjusting lever 17 moves into the interior of the lifting moving block 8, so that the surface of the lifting moving block 8 is no longer engaged with the limiting block 14, thereby adjusting the angle of the lifting plate 11 on the support crossbar 15, realizing the tilt adjustment of the lifting device. After adjusting to the required angle, release the pushing force on the adjusting lever 17, and the limiting block 14 is pushed to re-engage with the lifting plate 11 by the elastic potential energy of the spring 16, locking the angle between the lifting moving block 8 and the lifting plate 11 to remain fixed, ensuring the stability of the lifting device.

[0026] The bottom end of the lifting plate 11 is attached to a support crossbar 15, and both ends of the support crossbar 15 are fixedly connected to the lifting moving block 8.

[0027] A support crossbar 15 is provided to provide stable support for the lifting plate 11, reduce the load required for the limit block 14 during lifting, and prevent the limit block 14 from being damaged due to long-term pressure.

[0028] Example 2

[0029] Based on Example 1, please refer to Figures 1 to 4 As shown, the lifting device includes two sets of side baffles 2. The bottom ends of both sets of side baffles 2 are fixedly connected to the bottom extension plate 3. Both ends of the side baffles 2 are fixedly connected to connecting plates 7. A motor 6 is fixedly connected to the outer wall of one set of connecting plates 7. A threaded rod 9 is fixedly connected to the output end of the motor 6. A set of lifting moving blocks 8 is threadedly connected to the outer wall of the threaded rod 9.

[0030] The outer wall of the threaded rod 9 is movably sleeved inside two sets of connecting plates 7, and the guide slide rods 10 are fixedly sleeved inside the other two sets of connecting plates 7. The outer wall of the guide slide rods 10 is slidably sleeved with another set of lifting moving blocks 8.

[0031] Both sets of bottom extension plates 3 are fixedly connected to the bottom ends of hanging blocks 4, and the two sets of hanging blocks 4 are at the same height.

[0032] When handling is required, the motor 6 is started, and the output end of the motor 6 drives the threaded rod 9 to rotate between the two sets of connecting plates 7, thereby causing the lifting moving block 8 to move on the surface of the threaded rod 9, lifting the goods placed on the upper end of the lifting plate 11. The goods are lifted by mechanical transportation, reducing the intensity of loading and unloading for workers, reducing the demand for manual labor, and improving handling efficiency.

[0033] Working principle: In use, first, hang the hanging block 4 against the edge of the carriage to connect the handling equipment with the vehicle. If the vehicle is high, the tilt angle of the bottom extension plate 3 will rise. At this time, the lifting plate 11 at the top of the bottom extension plate 3 will also rise synchronously, tilting to a certain angle. Then, push the adjusting lever 17 to move to the other side, thereby driving the bottom limiting block 14 to move synchronously, so that the surface of the limiting block 14 is no longer engaged with the lifting plate 11. Then, push the limiting block 14 to slide at the top of the support crossbar 15, so that the lifting plate 11... When the objects are in a parallel state, the pushing force on the adjusting lever 17 is released. Under the influence of the elastic potential energy of the spring 16, the limiting block 14 is pushed to align with the round hole at the corresponding position of the lifting plate 11 and inserted, so that the parallel angle is kept fixed. When it is necessary to lift the goods, the motor 6 is started first. The output section of the motor 6 drives the threaded rod 9 to rotate inside the two sets of connecting plates 7, so that the lifting moving block 8 moves on the surface of the threaded rod 9, thereby raising the height of the lifting plate 11 and moving the goods from the lower position to the higher position, reducing manual lifting work and reducing the workload.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
