Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of logistics equipment, and more specifically, particularly relates to a logistics automatic lifting platform. Background Art
[0002] In addition to vehicles, logistics transportation equipment also uses conveyors, corresponding loading and unloading platforms, etc. For some special goods such as cigarette boxes, due to their vulnerability, they are mostly manually loaded and unloaded during the handling and loading and unloading of goods. However, the efficiency of manual loading and unloading is relatively low. In order to improve efficiency, mechanical conveying is used for automatic unloading. When the mechanical automatic transportation of goods reaches the loading and unloading platform, the height difference between the loading and unloading platform and the goods carriage causes the goods to be knocked and damaged.
[0003] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a logistics automatic lifting platform is provided in order to achieve a more practical value. Content of the Utility Model
[0004] In order to solve the above technical problems, the utility model provides a logistics automatic lifting platform to solve the problem that the height change of the carriage causes the goods to be knocked and damaged when the loading and unloading platform delivers goods automatically.
[0005] The purpose and effect of a logistics automatic lifting platform of the utility model are achieved by the following specific technical means:
[0006] A logistics automatic lifting platform includes a platform and two installation bases. Both sides of the platform are connected to the corresponding installation bases through lifting mechanisms. One end of the platform is provided with a connection mechanism, including a flap. The two ends of the platform are respectively provided with an active fixed side and a driven fixed side. The flap is rotatably arranged between the active fixed side and the driven fixed side. A second motor for driving the flap to rotate is arranged on the active fixed side.
[0007] Further, the lifting mechanism includes a plurality of connecting seats symmetrically distributed on both sides of the platform. A first motor is arranged on each of the two installation bases. Lifting devices are arranged at the bottoms of the connecting seats. The plurality of lifting devices on each side of the platform are driven by the corresponding first motor.
[0008] Further, the lifting device includes a screw jack. The worms of adjacent screw jacks are connected through a connecting rod. The output shaft of the first motor is connected to the worm of the screw jack at the end of the platform.
[0009] Further, a coupling is arranged between the connecting rod and the screw jack.
[0010] Further, a speed reducer is provided between the second motor and the active fixed side. One end of the speed reducer is connected to the shaft of the flap, and the other end is connected to the shaft of the second motor. A detection mechanism is provided on the flap.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] Through the lifting of the platform, the platform can be adjusted according to the height of the carriage. At the same time, during the unloading and loading process of the carriage, the flap can swing, so that after the height displacement caused by the change of the internal weight of the carriage is adjusted, the platform can still smoothly transition to the inside of the carriage without generating a height difference, reducing the damage caused by the bumps of the goods during automatic conveying.

[0020] Embodiment:
[0021] As shown in the attached Figure 1 to the attached Figure 2 figure:
[0022] The present utility model provides an automatic logistics lifting platform, which includes a platform 6 and two mounting bases 2. Both sides of the platform 6 are connected to the corresponding mounting bases 2 through lifting mechanisms. Before unloading and loading, the mounting bases 2 are used to be temporarily fixed at designated positions so that the platform 6 corresponds to the loading truck carriage. The lifting mechanism adjusts the height of the platform 6 to be flush with the carriage. One end of the platform 6 is provided with a connecting mechanism for transporting goods between the carriage and the platform 6. The connecting mechanism includes a flap 9. The two ends of the platform 6 are respectively provided with an active fixing side 10 and a driven fixing side 8. The flap 9 is rotatably arranged between the active fixing side 10 and the driven fixing side 8. A second motor 13 for driving the flap 9 to rotate is arranged on the active fixing side 10. The second motor 13 drives the flap 9 to rotate, so that after the height changes during the unloading and loading process of the carriage, the flap 9 between the platform 6 and the carriage can still be smoothly aligned and transitioned.
[0023] Among them, the lifting mechanism includes a plurality of connecting seats 14 symmetrically distributed on both sides of the platform 6. A first motor 1 is arranged on each of the two mounting bases 2. Lifting devices 5 are arranged at the bottoms of the connecting seats 14. The plurality of lifting devices 5 on each side of the platform 6 are driven by the corresponding first motor 1. In this embodiment, the lifting device 5 is a screw jack with a model of SWL10-U-T-C-L538. By driving the starting shaft of the screw jack through the first motor 1, the worm inside the screw jack rotates to drive the worm gear to rotate. The rotation of the worm gear causes the screw rod engaged with it to move up and down. The worms of adjacent screw jacks are connected through a connecting rod 3. The output shaft of the first motor 1 is connected to the worm of the screw jack at the end of the platform 6, so that the plurality of screw jacks on one side of the platform 6 are driven in series, and the first motor 1 can drive the plurality of connecting seats 14 on one side of the platform 6 to lift simultaneously.
[0024] And a coupling 4 is arranged between the connecting rod 3 and the screw jack, which is convenient for disassembling the connecting rod 3 and makes the driving rotation more stable.
[0025] Among them, a speed reducer 11 is arranged between the second motor 13 and the active fixed side 10. One end of the speed reducer 11 is connected to the shaft of the flap 9, and the other end is connected to the shaft of the second motor 13. A detection mechanism is arranged on the flap 9. The detection mechanism is an Omron M5 proximity switch, and the proximity switch is electrically connected to the first motor 1. When the carriage is unloading, the carriage slowly rises due to the reduction of goods. The platform 6 can always be in the same horizontal state as the carriage through the detection mechanism, so as to achieve precise control of the lifting speed and position of the platform 6, and thus the unloading equipment can easily enter and exit the carriage.
[0026] The embodiments of the present invention are given for purposes of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to better explain the principles of the present invention and its practical applications, and to enable those of ordinary skill in the art to understand the present invention so as to design various embodiments with various modifications suitable for specific purposes.
