[0052] The technical solution of the present invention will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0053] Example 1: Refer to Figures 1 to 5 As shown, a loading platform device on an intelligent stacker crane includes: a frame 1, on which a loading roller 2 and a transverse component 3 are mounted;

[0054] Guide components 6 are provided on both sides of the frame 1 in the width direction. The guide components 6 include four guide wheels 61 and two abutment wheels 62; the four guide wheels 61 are in pairs.

[0055] The loading platform 2 is mounted on the frame 1. The loading platform 2 includes several rollers 21 arranged in a row. Adjacent rollers 21 are driven by belts 211. The loading platform 2 is configured as two roller groups, which are located at both ends of the frame 1 in the length direction. The two roller groups can rotate independently. Each roller group includes several rollers 21 arranged in a regular pattern. Adjacent rollers 21 are driven by belts 211. One of the rollers in the roller group is configured as a power roller. The power roller is connected to a servo motor. Through the rotation of the power roller and the drive of the belts 211, the entire roller group rotates, which facilitates the transfer of goods.

[0056] The lateral movement assembly 3 includes two sets of mounting side frames 31. Fork assemblies 32 are mounted on the mounting side frames 31. The fork assemblies 32 are existing technology. Forks 321 are mounted on the fork assemblies 32 and can extend and retract along the length of the mounting side frames 31. The two sets of mounting side frames 31 are located on both sides of the loading platform 2. Mounting plates 311 are mounted at both ends of the mounting side frames 31 along their length. Mounting sliders 312 are mounted on the mounting plates 311. Mounting rails 11 are mounted at both ends of the frame 1 along their length. The mounting sliders 312 are adapted to the mounting rails 11. Through the cooperation of the mounting sliders 312 and the mounting rails 11, the two sets of mounting side frames 31 can slide along the mounting rails 11, allowing the mounting side frames 31 to slide towards or away from the loading platform 2.

[0057] The mounting side frame 31 is provided with two sets of fork assemblies 32 along its length. The two sets of fork assemblies 32 are located at both ends of the loading roller table 2 along its length, and the positions of the two sets of fork assemblies 32 correspond to the positions of the two sets of rollers.

[0058] The traverse assembly 3 also includes a drive assembly 4, which is mounted on the frame. The drive assembly 4 drives the traverse assembly 3 to slide synchronously towards or away from the loading table 2. The drive assembly 4 includes a drive chain 43, a first drive gear 41, and a second drive gear 42. The first drive gear 41 is connected to the output end of the drive motor 44. The first drive gear 41 and the second drive gear 42 are driven by the drive chain 43. The drive chain 43 is divided into an upper drive chain 431 and a lower drive chain 432 along the line connecting the first drive gear 41 and the second drive gear 42. Two sets of side frames 3 are mounted on the drive chain 3. 1 is connected to the upper drive chain 431 and the lower drive chain 432 respectively; when the drive motor 44 drives the first drive chain 41 and the second drive chain 42 to rotate, the upper drive chain 431 and the lower drive chain 432 move in opposite directions in the horizontal direction, and the two sets of mounting side frames 31 are connected to the upper drive chain 431 and the lower drive chain 432 respectively, so that by the forward and reverse rotation of the drive motor 44, the two sets of mounting side frames 31 can move synchronously towards or away from each other, so that the two mounting side frames 31 can move towards the cargo roll table 2 at the same time or move away from the cargo roll table 2 at the same time.

[0059] The two sets of mounting side frames 31 are respectively connected to the upper drive chain 431 and the lower drive chain 432 through the connecting block 33; the connecting block 33 is fixedly mounted on the mounting plate 311, and the drive chain 43 passes through the connecting block 33 and is fixedly connected to the connecting block 33.

[0060] The drive assembly 4 is configured in two sets, with each set located at one end of the frame 1 along its length. The two sets of drive assemblies 4 are connected and driven by a transmission assembly 5. The transmission assembly 5 includes a drive shaft 51 along the length of the frame 1, a first transmission gear 52 and a second transmission gear 53 located at both ends of the drive shaft 51, and a first output gear 54 coaxially connected to the first drive gear 41. The first transmission gear 52 and the second transmission gear 53 are respectively connected to the first output gear 54 of the two sets of drive assemblies 4. The two sets of drive assemblies 4 are connected by the transmission assembly 5, allowing one set to be equipped with a drive motor 44, thus enabling the rotation of both sets of drive assemblies 4. Furthermore, the two sets of drive assemblies 4 synchronously drive the mounting side frame 31, resulting in smoother movement of the mounting side frame 31.

[0061] The working principle of this embodiment is as follows: The drive motor 44 drives the first drive gear 41 to rotate. The first drive gear 41 drives the second drive gear 42 to rotate through the drive chain 43, so that the drive chain 43 drives the two sets of mounting side frames 31 to move away from each other, so that the forks 32 move away from the loading roller table 2. Then, the goods are placed on the loading roller table 2. The roller assembly on the loading roller table 2 rotates, so that the goods can move towards the center position of the loading roller table 2, so that the loading roller table 2 is filled with more goods. Then, the machine frame 1 is pulled up along the vertical track by the chain. During the upward movement of the machine frame 1, the guide wheel 61 and the abutment wheel 62 move along the vertical track. After reaching the designated position, the drive motor 44 rotates in the opposite direction, so that the two sets of mounting side frames 31 move closer to each other, so that the forks 32 move to the top of the loading roller table 2. The rollers 21 on the loading roller table 2 rotate, and at the same time, the forks 321 of the fork assembly 32 extend. The forks 321 and the rollers 21 cooperate to push the goods onto the shelf.

[0062] In this invention, by setting up a loading platform 2 and transferring goods via rollers 21, more goods can be placed on the rollers 21, significantly improving the cargo handling capacity compared to existing technologies. Simultaneously, by setting up fork assemblies 32, the ability to assist in cargo handling is further enhanced. The arrangement of two sets of rollers and two sets of fork assemblies 32 allows for simultaneous cargo handling in different directions, further improving the cargo handling capacity.

[0063] Example 2: Refer to Figures 1 to 8 As shown, this embodiment is structurally similar to Embodiment 1, except that the two sets of mounting side frames 31 are respectively connected to the upper drive chain 431 and the lower drive chain 432 via a connecting assembly 7; the connecting assembly 7 includes:

[0064] Vertical slide rail 71 is fixedly installed at the end of the mounting side frame 31. Specifically, there are three vertical slide rails 71, which are fixedly installed on the mounting plate 311.

[0065] The vertical slider 72 cooperates with the vertical slide rail 71. The vertical slider 72 slides along the vertical slide rail 71. The two ends of the vertical slider 72 along the length direction of the drive chain 43 are respectively provided with a first guide surface 721 and a second guide surface 722.

[0066] The snap-fit ​​tooth assembly 73 is disposed on the upper and lower end faces of the vertical slider 72. The snap-fit ​​tooth assembly 73 includes a plurality of snap-fit ​​teeth 731, which snap-fit ​​with the drive chain 43.

[0067] A first guide block 74 and a second guide block 75 are provided. The first guide block 74 is provided with a first inclined surface 741, and the second guide block 75 is provided with a second inclined surface 751. The first guide block 74 and the second guide block 75 are respectively provided at both ends of the sliding stroke of the mounting side frame 31.

[0068] A locking structure 8 is provided between the vertical slider 72 and the vertical slide rail 71; the locking structure 8 includes:

[0069] Guide groove 81 is provided on vertical slide rail 71. A protrusion 811 is provided in guide groove 81. The two sides of the protrusion 811 form two inclined guide surfaces 812.

[0070] The guide pin 82 and the vertical slider 72 are provided with a mounting hole 723 that is perpendicular to the vertical slide rail 71. The guide pin 82 is slidably disposed in the mounting hole 723. A spring 83 is provided in the mounting hole 723, and the spring 83 abuts against the bottom of the mounting hole 723 and between the guide pin 82.

[0071] In Embodiment 1, the two sets of mounting side frames 31 are connected to the upper drive chain 431 and the lower drive chain 432 respectively via connecting blocks 33. After long-term use, because the connecting blocks 33 are used, they can only be fixed to a few fixed sprockets of the drive chain 43. Prolonged stress makes the sprockets prone to breakage. Simultaneously, because the drive motor 44 needs to rotate forward and reverse to move the mounting side frames 31, the sprockets on the drive chain 43 and the connecting blocks 33 are subjected to forces in opposite directions, making the sprockets even more prone to breakage during actual use. This embodiment is designed to improve the service life of the drive chain 44 and ensure the overall structural lifespan.

[0072] The working principle of this embodiment is as follows: Figure 6 or Figure 7As shown, taking the movement of the right-side mounting bracket 31 as an example, the drive motor 44 rotates, causing the upper drive chain 431 to move to the left. At this time, the locking teeth 731 on the upper end face of the vertical slider 72 engage with the upper drive chain 431. The upper drive chain 431 drives the locking teeth 731 to move to the left, which in turn drives the vertical slider 72 to move to the left. The vertical slider 72 then drives the mounting plate 311 on the mounting bracket 31 to move to the left. When the first guide surface 721 contacts the first inclined surface 741, the interaction between the first guide surface 721 and the first inclined surface 741 causes the first guide surface 721 to move along... The vertical slider 72 moves downward along the first inclined surface 741, causing the upper end face of the vertical slider 72 to disengage from the upper drive chain 431, and the lower end face of the vertical slider 72 to engage with the lower drive chain 432. At this point, the mounting side frame 31 has moved to the end closest to the loading platform 2. When the mounting side frame 31 needs to move away from the loading platform 2, the drive motor 44 continues to rotate. Note that the drive motor 44 rotates in the same direction as before. At this time, the lower drive chain 432 drives the engagement teeth 731 to move to the right, causing the vertical slider 72 to move the mounting side frame. The mounting plate 311 on 31 moves to the right. When the second guide surface 722 contacts the second inclined surface 751, the second guide surface 722 and the second inclined surface 751 interact, causing the second guide surface 721 to move upward along the second inclined surface 751, causing the vertical slider 72 to move upward, causing the locking teeth 731 on the lower end face of the vertical slider 72 to disengage from the lower drive chain 432, and causing the locking teeth 731 on the upper end face of the vertical slider 72 to engage with the upper drive chain 431. At this time, the mounting side frame 31 has just moved to the end away from the loading table 2. By repeating the above process, the mounting side frame 31 can be moved forward. The drive chain 43 moves towards or away from the loading platform 2. Because the drive motor 44 moves in one direction, the force exerted by the locking teeth 731 on the chain shaft of the drive chain 43 is unidirectional, thus improving the service life of the drive chain 43. Furthermore, when the locking teeth 731 engage with the drive chain 43, each time the vertical slider 72 slides up and down, the locking teeth 731 engage at different positions on the drive chain 43, resulting in different force positions on the drive chain 43 each time. Compared to Embodiment 1, where the drive chain 43 is only subjected to force at one fixed position, this more effectively improves the service life of the drive chain 43.

[0073] The working principle of the card slot structure 8 is as follows: (Refer to...) Figure 8As shown, taking the mounting plate 311 on the mounting bracket 31 on the right as an example, when the vertical slider 72 moves to the left through the engaging teeth 731 on the upper end face, the guide pin 82 is acted upon by the guide surface 812 above the protrusion 811, pressing against the upper end of the guide surface 812, which is the upper end of the guide groove 81; when the vertical slider 72 moves to the left, the first guide surface 721 contacts the first inclined surface 741, causing the engaging teeth 731 on the upper end face of the vertical slider 72 to slide downwards during the downward movement of the vertical slider 72, and the engaging teeth 731 gradually disengage from the upper drive chain 431, and the guide pin 72 also slides downwards along the guide surface 812; when the engaging teeth 731 move from the upper end face... Before the drive chain 431 disengages, the guide pin 72 slides downward and passes over the protrusion 811. After the guide pin 72 passes over the protrusion 811, the guide pin 72 slides to the bottom of the guide groove 81 through the action of the guide surface 812 below the protrusion 811. The guide pin 72 also drives the vertical slider 72 to move downward, so that the locking teeth 731 on the lower end face of the vertical slider 72 are locked with the lower drive chain 432. Similarly, when the vertical slider 72 moves to the right and the second guide surface 722 abuts against the second inclined surface 751, the locking teeth 731 are also locked with the upper drive chain 431 through the action of the guide pin 82 and the guide groove 81.

[0074] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
