Description

Technical Field

[0001] The utility model relates to the technical field of logistics lifting devices, and particularly relates to a logistics lifting device. Background Art

[0002] With the rapid development of the economy and the rise of e-commerce, the business volume of the logistics industry has shown an explosive growth. In the process of storing, handling and loading / unloading goods, efficient and safe equipment is needed to improve logistics efficiency. As a device that can quickly and accurately achieve vertical transportation of goods, the logistics lifting device meets the urgent needs of the logistics industry to improve operation efficiency and reduce labor intensity.

[0003] The rotation of the transport pallet can only be achieved by the rotation of the forklift. It is fixed itself. Therefore, during transportation, if the space at the unloading point is small and the forklift cannot turn, and it can only enter and exit straight.

[0004] The existing patent (publication number: CN211283579U) is a logistics lifting device. Through the middle partition of the traditional transport pallet and the use of a flexible connection section, a forklift insertion rod is installed on each bracket, and the distance between the two rotating mechanisms can be adjusted according to different forklift models to meet the insertion of different models of forklifts. And during unloading, only the bracket needs to be rotated, and the entire forklift does not need to be rotated to complete unloading, which is very labor-saving. The telescopic frame can be driven by an oil cylinder to realize the lifting adjustment of the height, which is applicable to various handling working conditions and has strong practicability.

[0005] In view of the above problems, the existing patent gives a solution. The spiral lifting platform of the existing logistics lifting device mainly drives the lead screw through a motor to realize the rise or fall of the lifting platform.

Detailed implementation manner

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-5 , the present invention provides a technical solution:

[0028] A logistics lifting device includes a base 1. Both sides of the top of the base 1 are fixedly connected with support plates 2. A cavity 3 is opened inside the support plate 2. A servo motor 4 is fixedly connected to the bottom inside the support plate 2. The output end of the servo motor 4 is fixedly connected with a screw 5. The top of the screw 5 is threadedly connected with a connecting block 6. Both sides of the top of the connecting block 6 are fixedly connected with support blocks 7. A placing component 8 is arranged on the top of the support block 7. An auxiliary component 9 is fixedly connected to the inner side of the support plate 2. The auxiliary component 9 includes a placing block 901 fixedly connected to the inner side of the support plate 2;

[0029] The placing component 8 includes a placing plate 801 fixedly connected to the top of the support block 7. Both sides of the top of the placing plate 801 are fixedly connected with fixing blocks 802. A groove 803 is opened inside the fixing block 802. The rear side of the left fixing block 802 is fixedly connected with a motor body 804. The output end of the motor body 804 penetrates through the rear side of the fixing block 802. The output end of the motor body 804 is fixedly connected with a double-axis lead screw 805. The double-axis lead screw 805 is located inside the groove 803. The front side of the double-axis lead screw 805 is rotatably connected with the inside of the groove 803. The outer side of the double-axis lead screw 805 is threadedly connected with a limiting plate 806. The inner side of the limiting plate 806 is fixedly connected with a rubber block 807.

[0030] In this embodiment: By starting the servo motor 4, then the output end of the servo motor 4 drives the double-axis lead screw 805 to rotate. Then, the rotation of the double-axis lead screw 805 causes the limit plate 806 threadedly connected to the outside to move along the thread direction of the double-axis lead screw 805. Then, the rubber block 807 inside the limit plate 806 contacts the goods, thereby limiting and fixing the goods. When the transportation of the goods is completed, the servo motor 4 drives the double-axis lead screw 805 to rotate in the reverse direction. Then, the rotation of the double-axis lead screw 805 causes the limit plate 806 threadedly connected to the outside to move along the thread direction of the double-axis lead screw 805, thereby releasing the clamping and fixing of the goods. Compared with the existing logistics lifting device, it can effectively fix the goods, prevent the goods from moving or shaking during the lifting process, and ensure the stability and safety of the transportation process.

[0031] Specifically, as Figure 3 shown, a placement groove 902 is formed inside the placement block 901. A drive motor 903 is fixedly connected to the right side inside the placement groove 902. The output end of the drive motor 903 is fixedly connected to a threaded rod 904. A pressing plate 905 is threadedly connected to the outside of the threaded rod 904. The left side of the threaded rod 904 is rotatably connected to the inside of the placement groove 902.

[0032] Specifically, as Figure 3 、 Figure 5 shown, a pressing block 906 is slidably connected to the bottom of the pressing plate 905. A supporting plate 907 is fixedly connected to the bottom of the pressing block 906. Auxiliary blocks 908 are fixedly connected to both sides of the bottom of the supporting plate 907. The bottoms of the auxiliary blocks 908 penetrate through the top of the base 1, and a bottom plate 909 is fixedly connected to the bottoms of the auxiliary blocks 908.

[0033] Specifically, as Figure 3 、 Figure 5 shown, a return spring 910 is fixedly connected to the top of the supporting plate 907. The bottom of the return spring 910 is bolted to the top of the base 1.

[0034] In this embodiment: By starting the driving motor 903, the output end of the driving motor 903 drives the threaded rod 904 to rotate, and then drives the extrusion plate 905 connected by external threads to move. Then, the extrusion plate 905 moves to the right according to the rotation direction of the threaded rod 904, so that the extrusion plate 905 generates a downward pressure on the inclined surface at the top of the extrusion block 906, causing the auxiliary plate 907 fixed to the bottom of the extrusion block 906 to move downward. Then, the auxiliary block 908 moves along with the auxiliary plate 907, making the bottom plate 909 contact the ground. When the auxiliary plate 907 moves downward, during the process of the auxiliary plate 907 moving downward along with the extrusion block 906, a downward elastic force is generated on the auxiliary spring. When the use of the logistics lifting device is completed, start the driving motor 903, and drive the threaded rod 904 to rotate in the reverse direction through the reverse rotation of the driving motor 903, so that the extrusion plate 905 moves to the left to end the downward pressure on the top of the extrusion block 906. Then, the auxiliary plate 907 is moved upward by the elastic force of the return spring 910 to release the contact between the bottom plate 909 and the ground. Compared with the existing logistics lifting device, the stability of the logistics lifting device on uneven ground is improved, the situations of shaking and tilting are reduced, and the safety hazard is lowered.

[0035] Specifically, as Figure 4 shown, sliding grooves 10 are opened on both sides inside the support plate 2. The inside of the sliding grooves 10 is slidably connected with sliding blocks 11, and the inside of the sliding blocks 11 is fixedly connected to the outside of the connecting block 6.

[0036] Specifically, as Figure 5 shown, a limiting rod 12 is fixedly connected to the top of the base 1. The top of the limiting rod 12 penetrates through the bottom of the auxiliary plate 907, and the limiting rod 12 is located inside the return spring 910.

[0037] In this embodiment: By providing the sliding grooves 10 and the sliding blocks 11, when the servo motor 4 drives the screw rod 5 to rotate, it then drives the connecting block 6 to move, and at the same time limits the movement process of the connecting block 6 to prevent the movement trajectory of the connecting block 6 from deviating, resulting in situations such as shaking and tilting during the rising and falling processes of the device. By providing the limiting rod 12, it can limit the movement process of the auxiliary plate 907 while the return spring 910 drives the auxiliary plate 907 to move downward for resetting, to prevent the deviation of its upward reset trajectory.

[0038] Specifically, as Figure 2 shown, a support rod 13 is bolted inside the right fixing block 802, and the front side of the support rod 13 penetrates through the rear side of the limiting plate 806.

[0039] Specifically, as Figure 1 shown, a mounting seat 14 is fixedly connected to the bottom of the base 1, and a universal wheel 15 is rotatably connected inside the mounting seat 14.

[0040] In this embodiment: By providing the support rod 13, during the rotation of the double-axis lead screw 805 driven by the motor body 804 to drive the limit plate 806 to move, the movement trajectory of the limit plate 806 can be limited. By providing the mounting seat 14 and the universal wheels 15, the logistics lifting device can move flexibly, so as to facilitate the loading, unloading and transportation of goods at different positions.

[0041] Working principle: During the use of the logistics lifting device, first place the goods to be transported on the top of the placement plate 801, then start the servo motor 4. Next, the output end of the servo motor 4 drives the double-axis lead screw 805 to rotate. Then, the rotation of the double-axis lead screw 805 causes the limit plate 806 threadedly connected to the outside to move along the thread direction of the double-axis lead screw 805. Then, the rubber block 807 inside the limit plate 806 contacts the goods, thereby limiting and fixing the goods. Then, start the servo motor 4. While the servo motor 4 rotates, it drives the screw rod 5 to rotate. Then, the connecting block 6 moves upward according to the rotation direction of the screw rod 5. Then, the connecting block 6 drives the support block 7 to move downward. Then, the support block 7 drives the support plate 2 to move upward. At the same time, by starting the driving motor 903 of the body 804, the output end of the driving motor 903 drives the threaded rod 904 to rotate. Then, it drives the pressing plate 905 threadedly connected to the outside to move. Then, the pressing plate 905 moves to the right according to the rotation direction of the threaded rod 904, so that the pressing plate 905 generates a downward pressure on the inclined surface at the top of the pressing block 906, causing the auxiliary plate 907 fixed to the bottom of the pressing block 906 to move downward. Then, the auxiliary block 908 moves along with the auxiliary plate 907, so that the bottom plate 909 contacts the ground. This solves the problem that the screw-type lifting platform of the existing logistics lifting device mainly drives the lead screw by the motor to realize the rise or fall of the lifting platform. However, when used on uneven ground, since the supporting feet cannot fully contact the ground due to the uneven ground, the device will shake, tilt, etc., increasing potential safety hazards. And during the lifting operation, the movement of the load in the lifting device affects the stability and safety of the transportation process.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
