[0030] Example 1, with reference to Figure 1-Figure 3 , which is the first embodiment of the present invention, provides a four-way pallet shuttle for a stereoscopic warehouse. The device includes: a shuttle body 100, a support unit 200, and an adjustment unit 300.

[0031] The shuttle body 100 and the support unit 200 include a support assembly 201 disposed inside the shuttle body 100 for supporting and fixing the cargo; The adjusting unit 300 comprises a driving assembly 301 arranged in the shuttle vehicle body 100 and used for driving the shuttle vehicle body 100, and an adjusting assembly 302 arranged on the driving assembly 301 and used for changing the moving direction, and the adjusting assembly 302 is fixedly connected with the shuttle vehicle body 100. During the transportation of the goods by the shuttle vehicle body 100, the shuttle vehicle body 100 moves to the bottom of the goods in the warehouse, the positioning and calibration of the bottom of the goods are completed by the positioning detection device in the shuttle vehicle body 100, then the supporting assembly 201 is started, so that the supporting plate 2012 in the supporting assembly 201 moves upward, and the supporting plate 2012 contacts the bottom of the goods during the movement, so that the turnover clamping block 2014 in the supporting assembly 201 is turned over and fixed on the bottom of the goods through the reverse extrusion of the bottom of the goods, the support and fixation of the goods are strengthened, the stability of the goods during the transportation is ensured, after the goods are supported and fixed, the driving assembly 301 drives the shuttle vehicle body 100 to move and transport the goods, when moving to the turning track, the shuttle vehicle body 100 turns, the adjusting assembly 302 starts to drive the moving wheel 3019 in the driving assembly 301 to rotate, the moving wheel 3019 is adjusted, so that the moving wheel 3019 can change from the longitudinal direction to the vertical direction, then the transportation of the goods is continued, the shuttle vehicle and the goods are prevented from shaking due to the vibration, the vibration is easy to cause the gravity center of the goods to deviate, so that the goods fall, and when the shuttle vehicle body 100 needs to turn, the driving direction can be changed at any time, so that the vibration generated during the height difference adjustment of the wheels is avoided, and the stability of the goods during the transportation and the flexibility of the shuttle vehicle body 100 are further ensured.

[0032] In use, during the process of transporting goods by the shuttle vehicle body 100, the shuttle vehicle body 100 moves to the bottom of the goods in the warehouse, and the positioning and calibration of the bottom of the goods are completed by the positioning detection device inside the shuttle vehicle body 100, then the support assembly 201 is started, so that the support plate 2012 inside the support assembly 201 moves upward, and the support plate 2012 contacts the bottom of the goods during the movement, and the reverse extrusion of the bottom of the goods makes the turnover clamping block 2014 inside the support assembly 201 turn over and be fixed on the bottom of the goods, so as to strengthen the support and fixation of the goods and ensure the stability of the goods during transportation. After supporting and fixing the goods, the driving assembly 301 starts to drive the shuttle vehicle body 100 to move and transport the goods. When moving to the turning track, the shuttle vehicle body 100 turns, the adjusting assembly 302 starts to shrink the moving wheel 3019 inside the driving assembly 301 to rotate, starts to adjust the moving wheel 3019, so that the moving wheel 3019 can change from longitudinal to vertical in place, and then continues to transport the goods. The shuttle vehicle and the goods are prevented from shaking due to vibration, which is easy to cause the center of gravity of the goods to deviate and cause the goods to fall. When the shuttle vehicle body 100 needs to turn, the driving direction can be changed at any time, so as to avoid the vibration generated when the wheels are adjusted in height difference, and further ensure the stability of the goods during transportation and the flexibility of the shuttle vehicle body 100.

[0033] Example 2, with reference to Figures 1-8For the second embodiment of the application, which is different from the first embodiment, the support assembly 201 includes an electric push rod 2011 arranged inside the shuttle vehicle body 100, and a support plate 2012 arranged at the output end of the electric push rod 2011, and the support plate 2012 is in sliding connection with the shuttle vehicle body 100. The inside of the support plate 2012 is provided with a rotating groove 2013, and the rotating groove 2013 is rotatably provided with a rotating piece 2015, and the rotating piece 2015 is in rotary connection with the support plate 2012. The outer diameter of the rotating piece 2015 is provided with a turnover clamping block 2014, and the turnover clamping block 2014 is in rotary connection with the support plate 2012. When the shuttle vehicle body 100 transports goods, after the shuttle vehicle body 100 moves to the bottom of the goods in the warehouse, the shuttle vehicle body 100 itself detects and corrects the bottom of the goods, so that the shuttle vehicle body 100 can be accurately aligned at the bottom of the goods. Then the electric push rod 2011 inside the shuttle vehicle body 100 works and starts to extend upward. In the process of upward extension of the electric push rod 2011, the support plate 2012 at the top of the electric push rod 2011 also moves upward together, until the support plate 2012 is attached to the bottom of the goods. When the support plate 2012 is attached to the bottom of the goods, the goods also extrude the turnover clamping block 2014, so that the rotating piece 2015 inside the turnover clamping block 2014 rotates in the rotating groove 2013, so that the turnover clamping block 2014 is clamped around the goods, and the goods are limited, to ensure the stability of the goods during transportation.

[0034] In use, when the shuttle vehicle body 100 transports goods, after the shuttle vehicle body 100 moves to the bottom of the goods in the warehouse, the shuttle vehicle body 100 itself detects and corrects the bottom of the goods, so that the shuttle vehicle body 100 can be accurately aligned at the bottom of the goods. Then the electric push rod 2011 inside the shuttle vehicle body 100 works and starts to extend upward. In the process of upward extension of the electric push rod 2011, the support plate 2012 at the top of the electric push rod 2011 also moves upward together, until the support plate 2012 is attached to the bottom of the goods. When the support plate 2012 is attached to the bottom of the goods, the goods also extrude the turnover clamping block 2014, so that the rotating piece 2015 inside the turnover clamping block 2014 rotates in the rotating groove 2013, so that the turnover clamping block 2014 is clamped around the goods, and the goods are limited, to ensure the stability of the goods during transportation.

[0035] The rest of the structure is the same as that of embodiment 1.

[0036] Embodiment 3, refer to Figures 1-10, which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the driving component 301 includes a motor 3011 arranged inside the shuttle body 100, a transmission member 3012 arranged at the output end of the motor 3011, a rotating rod 3013 arranged inside the transmission member 3012, a cross steering shaft 3014 arranged on both sides of the rotating rod 3013, and a driving rod 3015 arranged at the other end of the cross steering shaft 3014, and the driving rod 3015 is rotatably connected to the adjustment component 302, the outer diameter of the driving rod 3015 is provided with a gear 1 3016, the bottom of the gear 1 3016 is meshed with a gear 2 3017, the interior of the gear 2 3017 is provided with a rotating rod 3018, and the rotating rod 3018 is connected to the adjustment component 3018, and the support assembly 201 is connected to the cargo bottom. After that, the motor 3011 starts to drive the transmission member 3012 and the rotating rod 3013 to rotate, and the rotation of the rotating rod 3013 causes the cross steering shaft 3014 and the driving rod 3015 on both sides to rotate together. When the driving rod 3015 rotates, the gear 1 3016 also starts to rotate with the gear 2 3017, so that the gear 2 3017 rotates with the rotating rod 3018 and the moving wheel 3019, and the shuttle body 100 moves along the track to start transporting goods. When the shuttle body 100 moves to the track intersection, the motor 3011 retracts inward, causing the adjustment rod 3022 to rotate inside the rotating shaft 3023, and drives the rotating shaft 3023 and the rotating part 3024 to rotate. When the rotating part 3024 rotates, the cross-steering shaft 3014 on the top begins to adjust its angle as the rotating shaft 3023 and the rotating part 3024 rotate, so that the rotating part 3024 can rotate with the driving rod 3015, gear 1 3016 and gear 2 3017 and the moving wheel 3019. Because the cross-steering shaft 3014 is a three-section adjustment shaft, the cross-steering shaft 3014 becomes a bent state after the moving wheel 3019 adjusts its moving direction to cooperate with the rotating shaft 3023 and the rotating part 3024 to change the direction of the moving wheel 3019, so that the moving wheel 3019 completes the turn and starts to turn for mobile transportation, and no shaking will occur during the turning process.At the same time, it can turn in situ at any location, realizing the flexible transformation of the moving wheel 3019 from longitudinal to vertical. At the same time, when the moving wheel 3019 moves from vertical to longitudinal direction, only the two-way push rod 3021 needs to be extended in the opposite direction to make the rotating shaft 3023 and the rotating part 3024 bent again, and the cross steering shaft 3014 becomes vertical, ensuring that the drive of the motor 3011 can be transmitted to the driving rod 3015 and the gear 1 3016 to ensure the movement of the moving wheel 3019, so that there is no need to rely on switching the height difference of the moving wheel 3019 to adjust the direction, avoiding the vibration caused by the height difference adjustment, further ensuring the stability of cargo transportation, and at the same time giving the shuttle car body a high degree of steering flexibility, so that it can change the driving direction anytime and anywhere, efficiently complete the transportation task, and overall improve the transportation efficiency and reliability of the shuttle car.

[0037] During use, after the shuttle body 100 moves to the bottom of the cargo and the support assembly 201 supports and fixes the cargo, the motor 3011 starts to drive the transmission member 3012 and the rotating rod 3013 to rotate, and through the rotation of the rotating rod 3013, the cross steering shaft 3014 and the driving rod 3015 on both sides rotate together. When the driving rod 3015 rotates, the gear 1 3016 also starts to rotate with the gear 2 3017, so that the gear 2 3017 rotates with the rotating rod 3018 and the moving wheel 3019, and the shuttle body 100 moves along the track to start transporting the cargo. When the shuttle body 100 moves to the intersection of the track, the motor 3011 retracts inward, causing the adjustment rod 3022 to rotate inside the rotating shaft 3023, and drives the rotating shaft 3023 and the rotating part 3024 to rotate. They rotate together. When the rotating part 3024 rotates, the cross-steering shaft 3014 on the top begins to adjust its angle as the rotating shaft 3023 and the rotating part 3024 rotate, so that the rotating part 3024 can rotate with the driving rod 3015, gear one 3016 and gear two 3017 together with the moving wheel 3019. Because the cross-steering shaft 3014 is a three-section adjustment shaft, the cross-steering shaft 3014 becomes a bent state after the moving wheel 3019 adjusts its moving direction to cooperate with the rotating shaft 3023 and the rotating part 3024 to change the direction of the moving wheel 3019, so that the moving wheel 3019 completes the turning and starts to turn for mobile transportation. There will be no shaking during the turning process, and at the same time, it can turn in place at any location, realizing the flexible transformation of the moving wheel 3019 from longitudinal to vertical.

[0038] At the same time, when moving from vertical to longitudinal direction, only the two-way push rod 3021 needs to be extended in the opposite direction to make the rotating shaft 3023 and the rotating part 3024 bent again, and the cross steering shaft 3014 becomes vertical, ensuring that the drive of the motor 3011 can be transmitted to the driving rod 3015 and the gear 1 3016 to ensure the movement of the moving wheel 3019, so that there is no need to rely on switching the height difference of the moving wheel 3019 to adjust the direction, avoiding the vibration caused by the height difference adjustment, further ensuring the stability of cargo transportation, and at the same time giving the shuttle car body a high degree of steering flexibility, so that it can change the driving direction anytime and anywhere, efficiently complete the transportation task, and overall improve the transportation efficiency and reliability of the shuttle car.

[0039] The remaining structures are the same as those of Example 2.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
