[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please refer to Figures 1-5. The technical solution provided by this utility model is as follows:

[0026] A pallet-type cargo handling four-way shuttle includes a base 1, a shell 2 is provided on the top of the base 1, an adjustable pallet assembly 4 is provided inside the shell 2, and a telescopic rotating detection assembly 5 is provided on the front side of the shell 2.

[0027] The adjustable tray assembly 4 includes a main tray 401 fixedly connected to the top of the housing 2. A dual-axis drive motor 402 is fixedly connected inside the housing 2. Drive screws 403 are fixedly connected to both sides of the dual-axis drive motor 402. A connecting seat 404 is threadedly connected to the outer side of the drive screw 403. A side support plate 405 is fixedly connected to the inner side of the connecting seat 404. The side support plate 405 is slidably connected to the main tray 401. A limiting slide rail 406 is fixedly connected to the bottom of the side support plate 405. The limiting slide rail 406 is fixedly connected to the housing 2. A partition plate 407 is fixedly connected to the inner side of the side support plate 405. The partition plate 407 is slidably connected to the housing 2.

[0028] In this embodiment: the dual-axis drive motor 402 is started by the control circuit board 6, and then the two output shafts of the dual-axis drive motor 402 rotate synchronously, driving the drive screws 403 on both sides to rotate. The drive screws 403 cause the connecting seat 404 to move axially along the drive screws 403 through thread transmission. The side support plate 405 on the inner side of the connecting seat 404 slides on the surface of the main pallet 401. The limiting slide rail 406 at the bottom of the side support plate 405 is fixed to the outer shell 2, limiting the movement trajectory of the side support plate 405 and ensuring that it slides smoothly in the horizontal direction. At the same time, the inner partition plate 407 is slidably connected to the outer shell 2, which enhances the structural stability of the side support plate 405 when it moves. When the side support plate 405 moves to the preset position, the dual-axis drive motor 402 stops rotating, and the overall width of the pallet is adjusted. When picking up goods, the hydraulic cylinder 3 is adjusted to push the pallet up to the cargo position height. The shuttle car moves forward so that the side support plate 405 is inserted into the bottom of the goods. Through the precise adjustment of the pallet size, it is ensured that the bottom of the goods is in full contact with the pallet to bear the load.

[0029] Specifically, as shown in Figure 3, the telescopic rotary detection component 5 includes a fixed frame 501 fixedly connected to the inner side of the outer shell 2. A telescopic cylinder 502 is fixedly connected to the rear side of the fixed frame 501. A support base 503 is fixedly connected to the output end of the telescopic cylinder 502. A limiting rod 504 is fixedly connected to the rear side of the support base 503. The limiting rod 504 is slidably connected to the outer shell 2.

[0030] Specifically, as shown in Figure 3, a rotating gimbal 505 is fixedly connected to the front side of the support base 503, and a lidar 506 is fixedly connected to the front side of the rotating gimbal 505.

[0031] Specifically, as shown in Figure 3, ultrasonic sensors 507 are provided on both sides of the support base 503, and the ultrasonic sensors 507 are located on both sides of the lidar 506.

[0032] In this embodiment: when the shuttle starts moving or approaches the target storage location, the control circuit board 6 controls the piston rod of the telescopic cylinder 502 to extend, pushing the support seat 503 forward. The limiting support rod 504 on the rear side of the support seat 503 slides inside the housing 2 to ensure the smooth movement of the support seat 503. The rotating gimbal 505 on the front side of the support seat 503 drives the lidar 506 to perform a 360-degree rotation scan. The lidar 506 emits a laser beam to detect surrounding obstacles and generate a three-dimensional environmental model. The ultrasonic sensors 507 on both sides of the support seat 503 simultaneously detect nearby obstacles and provide real-time feedback on obstacle distance information. The detection data is transmitted to the control circuit board 6 through the signal processing module. The control circuit board 6 analyzes the obstacle position and distance through an algorithm, generates obstacle avoidance commands, and sends them to the drive system to adjust the shuttle's driving path. When the shuttle turns or approaches the shelf, the extension length of the detection components can be adjusted through the telescopic cylinder 502 to expand the detection range and detect potential obstacles in advance.

[0033] Specifically, as shown in Figure 4, an adjusting hydraulic cylinder 3 is fixedly connected inside the base 1. The output end of the adjusting hydraulic cylinder 3 is fixedly connected to the outer shell 2. A control circuit board 6 is electrically connected to the inside of the adjusting hydraulic cylinder 3.

[0034] Specifically, as shown in Figure 4, a servo motor 7 is fixedly connected to the bottom of the base 1, and a transmission belt 8 is provided at the output end of the servo motor 7. Drive wheels 9 are provided on both sides of the transmission belt 8.

[0035] In this embodiment: By setting up an adjusting hydraulic cylinder 3 and a control circuit board 6, when the shuttle car travels to the vicinity of the target storage location, the control circuit board 6 sends a command to the adjusting hydraulic cylinder 3, causing the piston rod of the adjusting hydraulic cylinder 3 to extend and push the outer shell 2 and the top adjustable pallet assembly 4 to rise as a whole. At this time, the adjusting hydraulic cylinder 3, through its fixed connection with the outer shell 2, converts the thrust into precise adjustment of the pallet height, making the pallet plane flush with the height of the shelf storage location. During this process, the control circuit board 6 monitors the extension and retraction stroke of the adjusting hydraulic cylinder 3 in real time and ensures that the pallet rising height is accurately matched to the storage location through feedback data from the built-in sensor. By setting up a servo motor 7, a transmission belt 8, and drive wheels 9, after the operator issues a driving command through the warehouse management system, the control circuit board 6 triggers the servo motor 7 to start. The output shaft of the servo motor 7 drives the transmission belt 8 to rotate, and the drive wheels 9 on both sides of the transmission belt 8 rotate synchronously under the action of friction. The drive wheels 9 generate driving force through contact with the track surface, causing the shuttle car to travel forward or backward along the track. At the same time, by controlling the steering and speed of the servo motor 7, the shuttle car can move in four directions.

[0036] Specifically, as shown in Figure 5, guide wheels 10 are fixedly connected to the outer side of the base 1, and a protective shell 12 is fixedly connected to the outer side of the base 1. The protective shell 12 is located outside the guide wheels 10.

[0037] Specifically, as shown in Figure 1, an anti-slip pad 11 is attached to the top of the side support plate 405. The anti-slip pad 11 is made of rubber.

[0038] In this embodiment: By setting guide wheels 10 and protective shells 12, during the shuttle's operation, the guide wheels 10 on the outer side of the base 1 are always in contact with the side of the track, guiding the shuttle to travel along the center line of the track. When the shuttle turns or encounters a slight deviation from the track, the guide wheels 10 adaptively adjust their direction of travel through rolling friction to ensure that the shuttle does not deviate from the track. The protective shells 12 cover the outer side of the guide wheels 10, effectively preventing dust, debris, and other foreign objects from entering the bearings of the guide wheels 10, thus avoiding jamming or wear of the guide wheels 10 due to the accumulation of foreign objects. By setting anti-slip mats 11, when goods are placed on the pallet, the rubber anti-slip mats 11 on the top of the side support plate 405 directly contact the bottom of the goods. The textured surface of the anti-slip mats 11 increases the friction with the goods. During the shuttle's start-up, braking, or turning, the goods will not slide due to inertia. At the same time, the elastic cushioning effect of the rubber material can also reduce the vibration and impact on the goods during handling, improving the safety and stability of goods transportation.

[0039] Working Principle: When using a palletized four-way shuttle for cargo handling, the operator first issues a task instruction through the warehouse management system. Then, the control circuit board 6 receives the instruction and begins coordinating the operation of each component. First, the servo motor 7 at the bottom of the base 1 starts, driving the drive wheels 9 on both sides to rotate via the transmission belt 8. Simultaneously, the guide wheels 10 roll along the shelf track on the outside of the base 1, guiding the shuttle to smoothly travel to the vicinity of the target location. During this travel, the telescopic rotating detection component 5 on the front of the outer casing 2 is activated. Then, the telescopic cylinder 502 on the rear of the fixing frame 501 extends, pushing the support base 503 forward, causing the lidar 506 and ultrasonic... Wave sensor 507 extends out of housing 2, rotating gimbal 505 drives lidar 506 to perform 360-degree rotation scanning, and ultrasonic sensor 507 detects nearby obstacles in real time on both sides. Both transmit the detected environmental data to control circuit board 6 to ensure that the shuttle avoids obstacles during its journey. After reaching the target cargo location, the adjustable pallet assembly 4 is activated, and then the dual-axis drive motor 402 is started. Then, the drive screws 403 on both sides of the motor rotate, and the connecting seat 404, which is threaded to the drive screws 403, drives the side support plate 405 to slide on the main pallet 401. The overall width of the pallet is adjusted according to the size of the cargo. The bottom limit slide of the side support plate 405... The rail 406 is fixed to the outer shell 2 to ensure the stability of the side support plate 405 during sliding. The inner partition 407 is slidably connected to the outer shell 2 to further enhance the structural stability. After the pallet size is adjusted, the adjusting hydraulic cylinder 3 inside the base 1 extends under the control of the control circuit board 6, pushing the outer shell 2 and the pallet to a height level with the shelf position for easy retrieval. When retrieving goods, the pallet is raised to a suitable height, the shuttle moves forward to align the pallet with the bottom of the goods, and the side support plate 405 is inserted below. The dual-axis drive motor 402 adjusts the position of the side support plate 405 according to the size of the goods to adapt to the width of the goods. At the same time, the rubber anti-slip pad 11 on the top of the auxiliary support plate increases friction to prevent the goods from sliding. After the goods are transported, the adjusting hydraulic cylinder 3 retracts, the pallet lowers, and the shuttle moves towards the storage location. During the journey, the detection components continue to work to ensure safety. Upon reaching the storage location, the adjusting hydraulic cylinder 3 extends to raise the pallet to be level with the location, the shuttle moves forward to place the goods, and then the pallet lowers, the side support plate 405 retracts to the initial position, and the shuttle drives away to complete the task. Throughout the entire process of goods handling, its control circuit board 6 monitors the status of the components in real time and adjusts the driving speed and direction based on the detection information to ensure stable driving. In case of emergency, the operator can cut off the power through the emergency stop button to stop the shuttle immediately, ensuring the safety of personnel and equipment and achieving efficient and safe goods handling.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
