Description

Technical Field

[0001] This application relates to the technical field, and more specifically, to a logistics transportation loading and unloading equipment. Background Technology

[0002] Logistics transportation refers to the process of transferring goods or services from one place to another; logistics transportation methods include various modes such as road transportation, rail transportation, air transportation, and water transportation; different transportation methods have different advantages and disadvantages, and the choice needs to be made according to the actual situation.

[0003] When using loading equipment, such as trucks, to transport goods, loading is often done separately at multiple locations. Each time the goods are loaded, they need to be secured individually, and the goods from different transport locations need to be separated to prevent them from being transported to other locations. Usually, baffles are inserted between the goods in two areas to achieve separation. However, this method of operation is physically demanding for single workers and takes a long time. In addition, for large goods, the large contact area with the loading equipment leads to increased friction, which is inconvenient for single workers to place. It is necessary to use other transportation equipment and cooperate with multiple people for loading and unloading.

[0004] Therefore, a logistics transportation loading and unloading equipment is needed to solve the above problems. Utility Model Content

[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] To address the technical problems mentioned in the background section, some embodiments of this application provide a logistics transportation loading device, comprising: a loading box, with two rotatably connected opening and closing doors at the rear end of the loading box, the combined length of the two doors being less than the distance between the two inner end faces of the loading box; a loading platform installed at the inner end of the loading box and at the bottom of the loading box, the length of the loading platform being the same as the combined length of the two doors; connecting platforms fixed at both ends of the loading platform; sliding grooves evenly distributed front and back on the adjacent ends of the two connecting platforms; a rotating shaft capable of vertical movement installed at the sliding groove; and rollers fixed on the outer periphery of the rotating shaft.

[0007] Furthermore, the upper surface of the loading platform is provided with an opening groove corresponding to the upper and lower surfaces of the rollers. The rollers can move upward to extend out of the opening grooves. A gantry frame is provided at the far ends of the two connecting platforms. The gantry frame is provided with a partition for separating logistics items. The gantry frame is evenly distributed front and back. Two sets of left-right symmetrical guide rods are fixed inside the loading box. The guide rods extend front and back through the gantry frame and slide in cooperation with the gantry frame. The top of the gantry frame abuts against the upper inner surface of the loading box.

[0008] Furthermore, abutment plates are fixedly provided at both ends of the rotating shaft, and limiting members are fixedly provided at both ends of the rotating shaft. Bearings are installed between the abutment plates and the limiting members. The interior of each of the two connecting platforms is provided with an upper plate at the upper end and a lower plate at the lower end. The upper end of the upper plate is fixedly connected to the connecting platform, and the lower plate is slidably connected to the connecting platform. A power mechanism is installed at the rear end of each of the two connecting platforms. The power mechanism is used to control the forward and backward movement of the lower plate. A bearing end and a lifting end are provided on the upper surface of the lower plate. Both the bearing end and the lifting end can abut against the circumferential surface of the bearing. The lifting end is inclined downward and has a rounded corner. The rear end of the loading platform is inclined downward, and the edge of the rearmost end of the loading platform is fitted with the inner end face of the bottom side of the loading box.

[0009] Furthermore, the power mechanism can be connected and cooperate with the lower plate. The power mechanism includes a power motor fixed on the connecting platform and a threaded rod rotatably connected in the connecting platform. The threaded rod extends forward and is inserted into the lower plate and is threadedly engaged with the lower plate. The power output end of the power motor is connected to the power mechanism by a belt and pulley drive.

[0010] Furthermore, the guide rod passes through the end of the gantry frame and has a sliding hole. The sidewall of the sliding hole slides in conjunction with the guide rod. Sliding cavities are formed at the adjacent ends of the left and right supports of the sliding hole. Rotating rods are rotatably connected to both ends of the partition. Sliding blocks are fixed at the distant ends of the two rotating rods. The sliding blocks are inserted into the sliding cavities and slide up and down on the sidewalls of the sliding cavities. A handle is fixed at the rear end of the partition, and an insert is fixed at the front end of the partition. The upper part of the gantry frame has a downward-opening slot. A magnetic strip that can fit against the partition is fixed on the sidewall of the slot. Both the partition and the insert are magnetic.

[0011] Furthermore, the lower end of the sliding block is fixed with a telescopic sleeve located at the outer end and a spring located at the inner end. The telescopic sleeve can extend and retract up and down, and the spring can abut and compress against the lower side wall of the sliding cavity. The rotating rod is rotatably positioned at the middle position of the gantry frame, and the distance between the rotating rod and the insertion strip is less than the distance between the bottom wall of the sliding cavity and the top wall of the slot.

[0012] The beneficial effects of this application are as follows:

[0013] 1. The power mechanism controls the rollers to extend upwards, allowing them to support the materials instead of the loading platform. This converts sliding friction into rolling friction, improving the loading efficiency for large materials. After loading, the lower plate moves backward, causing the rollers to move downwards and retract into the opening slot of the loading box. This allows the upper surface of the loading platform to contact the materials, maintaining stability during transport. By moving the gantry back and forth, it is positioned between two logistics areas, separated by longitudinal partitions. This improves work efficiency during subsequent unloading, eliminating the need for staff to distinguish between the two areas.

[0014] 2. The forward and backward movement of the lower plate controls the vertical extension and retraction of the rollers. When the rollers extend, friction is reduced, facilitating the movement of large logistics items on the loading platform. The downward retraction of the rollers increases friction, ensuring the stability of the logistics items and reducing the impact of vibration during transportation. By installing a telescopic sleeve and spring under the sliding block, the insert can be inserted into the slot when the spring is compressed. In subsequent processes, the spring supports the partition, reducing the peak and valley values ​​of the vertical movement at the insert, preventing the insert from slipping out, and maintaining the separation effect of the partition. The magnetic attraction between the two ends of the magnetic strip and the insert further reduces the sliding distance of the insert and improves the stability of the insert in the slot.

[0032] It should also be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings. Unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other.

[0033] It should be noted that the concepts of "first" and "second" mentioned in this disclosure are used only to distinguish different devices, modules or units, and are not used to limit the order of functions performed by these devices, modules or units or their interdependencies.

[0034] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0035] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] Referring to Figures 1-3, a logistics transportation loading device includes: a loading box 10, with two rotatable doors 11 rotatably connected to the rear end of the loading box 10. The combined length of the two doors 11 is less than the distance between the two inner end faces of the loading box 10. A loading platform 12 is installed at the inner end of the loading box 10, located at the bottom of the loading box 10. The length of the loading platform 12 is the same as the combined length of the two doors 11. Connecting platforms 13 are fixed at both ends of the loading platform 12. Sliding grooves 14 are evenly distributed at the close ends of the two connecting platforms 13. A rotating shaft 15 capable of vertical movement is installed at the sliding groove 14. A roller 16 is fixed on the outer periphery of the rotating shaft 15. The rotating shaft 15 and the roller 16 are coaxially arranged. An opening groove corresponding to the roller 16 is opened on the upper end face of the loading platform 12. The roller 16 can move upward to extend out of the opening groove. The two connecting platforms 13... A gantry frame 30 is provided at the far ends of the loading container 10. The gantry frame 30 is equipped with partitions 36 for separating logistics items. The gantry frame 30 is evenly distributed front and back. Two sets of symmetrical guide rods 32 are fixed inside the loading container 10. The guide rods 32 extend forward and backward through the gantry frame 30 and slide in cooperation with it. The top of the gantry frame 30 abuts against the upper inner surface of the loading container 10. Specifically, the loading container 10 is mounted on a transport vehicle (such as a transport vehicle) for mobile transport. By opening the rear door 11, logistics items are placed into the loading container 10. Large objects can reduce the contact area by contacting the rollers 16 protruding from the upper end of the loading platform 12, thus moving and filling into the loading container 10 under the rolling of the rollers 16. After the logistics items in one transport area are filled, the gantry frame 30 is moved back and forth to separate the partitions 36. The system is set up vertically, and then the logistics items for the next transportation area are loaded, thus separating the logistics items for the two different transportation areas.

[0037] Reference Figure 8-11Both ends of the rotating shaft 15 are fixed with abutment plates, and both ends of the rotating shaft 15 are fixed with limiting members 18. A bearing 17 is installed between the abutment plate and the limiting member 18. The interior of each of the two connecting platforms 13 is provided with an upper plate 19 at the upper end and a lower plate 20 at the lower end. The upper end of the upper plate 19 is fixedly connected to the connecting platform 13, and the lower plate 20 is slidably connected to the connecting platform 13. The rear end of each of the two connecting platforms 13 is equipped with a power mechanism 21, which is used to control the forward and backward movement of the lower plate 20. The upper end surface of the lower plate 20 is provided with a bearing end 22 and a lifting end 23. Both the bearing end 22 and the lifting end 23 can abut against the circumferential surface of the bearing 17. The lifting end 23 is inclined downward and has a rounded corner. The rear end of the loading platform 12 is inclined downward, and the edge of the rearmost end of the loading platform 12 is aligned with the loading box 10. The bottom inner end face is fitted together. Specifically, the power mechanism 21 works to control the lower plate 20 to move forward, so that the lower plate 20, as shown in the loading box 10, abuts against the bearing 17 through the end face of the bearing end 22. At this time, the bearing 17 drives the sleeved rotating shaft 15 to move upward to the upper area of ​​the sliding groove 14, as shown in the figure. Figure 8 As shown, the upper plate 19 and the lower plate 20 form a fixed cavity to hold the bearing 17 through the interconnected openings. The upper plate 19 and the lower plate 20 have slots at their close ends. The bearing 17 is moved up and down in the slots to ensure that the roller 16 protrudes on the loading platform 12. Similarly, the lower plate 20 is moved backward by the operation of the power mechanism 21, so that the bearing 17 moves in contact with the lifting end 23, so that the rotating shaft 15 is located in the lower area of ​​the sliding groove 14. At this time, the roller 16 on the rotating shaft 15 is housed in the opening groove of the loading platform 12, thereby causing the roller 16 to lose contact with the material and prevent the material from moving during transportation. The inclined setting of the rear end of the loading platform 12 facilitates the contact between the material and the roller 16.

[0038] Referring to Figures 9-10, the power mechanism 21 can be connected and cooperated with the lower plate 20. The power mechanism 21 includes a power motor fixed on the connecting platform 13 and a threaded rod rotatably connected in the connecting platform 13. The threaded rod extends forward and is inserted into the lower plate 20 and is threadedly engaged with the lower plate 20. The power output end of the power motor is connected to the power mechanism 21 by a belt and pulley drive.

[0039] Reference Figure 4-7A guide rod 32 passes through the gantry frame 30 and has a sliding hole 33 at one end. The sidewall of the sliding hole 33 is slidably engaged with the guide rod 32. Sliding cavities 34 are provided at the close ends of the left and right supports of the sliding hole 33. Rotating rods 41 are rotatably connected to both ends of the partition plate 36. Sliding blocks 40 are fixed at the far ends of the two rotating rods 41. The sliding blocks 40 are inserted into the sliding cavities 34 and slide up and down on the sidewalls of the sliding cavities 34. A handle 37 is fixed at the rear end of the partition plate 36, and an insert 38 is fixed at the front end of the partition plate 36. The upper part of the gantry frame 30 has a slot 39 with an opening facing downwards. A magnetic strip 35 that can fit against the partition plate 36 is fixed on the sidewall of the slot 39. Both the partition plate 36 and the insert 38 are magnetic. A telescopic sleeve 42 located at the outer end and a spring 43 located at the inner end are fixed at the lower end of the sliding block 40. The telescopic sleeve 42 can extend and retract up and down, and the spring 43... The rotating rod 41 is rotatably positioned at the middle of the gantry 30, and the distance between the rotating rod 41 and the insert 38 is less than the distance between the bottom wall of the sliding cavity 34 and the top wall of the slot 39. Specifically, in the initial state, the partition 36 is positioned at the top of the gantry 30 and is magnetically attracted by the magnetic strip 35. The user can place the logistics item backward using the roller 16. After the logistics items at the same transportation location are collected, the staff pushes the gantry 30 backward by holding the handle 37. When the left and right supports of the gantry 30 are behind the logistics item, the staff pulls the handle 37 downward, thereby pulling the partition 36 out of the magnetic attraction state with the magnetic strip 35 (the rear end of the partition 36 first has the magnetic strip 35 on the rear side out of the magnetic attraction state, so that the partition 36 is in contact with the magnetic strip 35 on the front side). When the magnetic strip 35 rotates to a certain angle, and the magnetic strip 35 on the front can no longer support the magnetic force of the partition 36, the partition 36 completely disengages from the magnetic strip 35. At this time, the partition 36 is tilted, and the sliding block 40 moves steadily downward through its sliding connection with the side wall of the sliding cavity 34. The paper spring 43 abuts against the bottom wall of the sliding cavity 34. The operator can pull down the partition 36, causing the spring 43 to deform elastically, thereby causing the telescopic sleeve 42 to be in a contracted state. At this time, the insert 38 moves downward synchronously with the partition 36, thus passing through the magnetic strip 35 and being located directly below the slot 39. The operator releases the handle 37, causing the insert 38 to move downward under the spring force of the spring 43 and abut against the top wall of the slot 39. The two magnetic strips 35 continue to maintain the magnetic attraction state with the insert 38, and the partition 36... The vertical arrangement allows for the separation of logistics components between the front and rear areas.This enables rapid unloading during subsequent transportation of goods to different regions.

[0040] Working process or usage method:

[0041] 1. The power mechanism 21 operates to control the roller 16 to extend upwards, thereby allowing the roller 16 to replace the loading platform 12 in supporting the material, converting sliding friction into rolling friction, thus improving the loading efficiency of large material items. After loading is completed, the lower plate 20 is controlled to move backwards, causing the roller 16 to move downwards, and then the roller 16 is stored in the opening slot of the loading box 10, so that the upper surface of the loading platform 12 contacts the material, thereby maintaining stability during transportation. By moving the gantry 30 back and forth, the gantry 30 is positioned between the two logistics areas, and the longitudinal arrangement of the partition 36 achieves separation, thereby improving work efficiency in the subsequent unloading process, eliminating the need for staff to distinguish between the logistics items in the two areas.
