Description

Technical Field

[0001] The present application relates to the technical field related to warehousing and handling, and in particular to a heavy-duty four-way shuttle vehicle for dense storage warehouses. Background Art

[0002] The four-way shuttle is a highly automated logistics robot that can flexibly shuttle in all directions (front, back, left, right) in the warehouse to automatically identify and quickly move pallets or boxes. Its flexibility and efficiency make the four-way shuttle an important part of the modern intelligent warehousing system, which can significantly improve warehouse operation efficiency and reduce labor costs.

[0003] The current heavy-duty four-way shuttle is driven by three motors, with one driver for each direction of movement, or a hydraulic system for lifting. This results in a heavy load on the heavy-duty four-way shuttle, large drive components, and a small internal space for the four-way shuttle. The use of three motors and hydraulic lifting will increase the internal space occupied by the heavy-duty four-way shuttle, reduce the battery size, and thus reduce the battery life. The design of hydraulic lifting makes the internal structure of the four-way shuttle complex, with a high failure rate, and the hydraulic lifting speed is slow and inefficient.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] Embodiment 1

[0037] See also Figure 1 and Figure 2 The four-way vehicle 1 includes a frame body 14, an auxiliary rail wheel 5 is rotatably mounted on the frame body 14, and a main rail wheel 6 is rotatably mounted on a side plate 17. The auxiliary rail wheel 5 and the main rail wheel 6 have exactly the same structure. Slide blocks 16 are mounted at both ends of the side plate 17. The slide blocks 16 are mounted in cooperation with the slide rails 15 fixed on the frame body 14, and the side plate 17 can move up and down along the slide rails 15 on the frame body 14. The lifting motor 9 is fixed on the frame body 14 and connected to the gears in the wheel train 21. The gears at both ends of the wheel train 21 are equipped with cams 13. The lifting motor 9 drives the cam 13 to rotate through the wheel train 21, thereby driving the side plate 17 to move up and down. The lifting shaft 12 is fixedly connected to the wheel trains 21 on both sides of the four-way vehicle 1 to realize the synchronous up and down movement of the side plates 17 on both sides of the four-way vehicle 1. The lifting plate 7 is fixed on the side plates 17 on both sides of the four-way vehicle 1 and moves up and down with the side plates 17 on both sides.

[0038] The travel motor 8 drives the auxiliary rail wheel 5 and the main rail wheel 6 to rotate at the same time. The auxiliary rail shaft 11 passes through the two ends of the wheel box 22 and is connected to the auxiliary rail wheels 5 on both sides of the four-way vehicle 1 through the chain 20. The wheel box 22 is fixedly mounted on the frame body 14. The main rail shaft 10 passes through the two ends of the wheel box 22 and is connected to the main rail wheels 6 on both sides of the four-way vehicle 1 through the chain 20. The travel motor 8 is fixed on the wheel box 22, and the travel motor 8 is connected to the auxiliary rail shaft 11 and the main rail shaft 10 through the bevel gear spur gear inside the wheel box 22 to achieve the purpose of driving the auxiliary rail wheel 5 and the main rail wheel 6 by the travel motor 8.

[0039] The main rail wheels 6 on both sides of the four-way vehicle 1 are connected to the main rail shaft 10 through the universal joint coupling 23, so that the main rail wheels 6 are still driven by the travel motor 8 when moving up and down with the side plates 17, and the purpose of stable operation is achieved.

[0040] The travel motor 8 and the lifting motor 9 in the four-way vehicle 1 are powered by a battery 18 . When the battery power is less than 20%, the four-way vehicle 1 actively goes to a power supply point to charge through a power plug 19 .

[0041] The auxiliary rail wheels 5 on the same side of the four-way vehicle 1 are connected to the auxiliary rail shaft 11 through a chain 20, and the main rail wheels 6 on the same side are connected to the main rail shaft 10 through a chain 20. All auxiliary rail wheels 5 and main rail wheels 6 are driving wheels.

[0042] Since the main track 2 is lower than the auxiliary track 3, there will be a gap at the intersection of the auxiliary track 3 and the main track 2. When the four-way vehicle 1 runs along the auxiliary track 3 and passes through the gap, in order to ensure the stability of the four-way vehicle 1 in running and transporting goods, the four-way vehicle is designed with four pairs of auxiliary track wheels 5, and the center distance between every two pairs of auxiliary track wheels 5 is greater than the length of the gap, ensuring that at least three pairs of auxiliary track wheels 5 of the four-way vehicle 1 are on the auxiliary track 3 when passing through the gap, ensuring the stability of the vehicle body during operation.

[0043] When implementing it, refer to Figure 1-Figure 4 As can be seen from the figure, the main rail wheel 6 of the four-way vehicle 1 runs on the main track 2, and the auxiliary rail wheel 5 runs on the auxiliary track 3. The main track 2 is lower than the auxiliary track 3.

[0044] The four-way vehicle 1 enters the bottom of the cargo 4 along the auxiliary track 3, and the lifting motor 9 drives the cam 13 to rotate through the wheel train 21, thereby driving the side plate 17 to move upward, so that the lifting plate 7 moves upward to lift the cargo 4. Then the four-way vehicle 1 enters the main track 2 along the auxiliary track 3, and then the cam 13 continues to rotate, the main track wheel 6 moves downward to contact the main track 2 and lifts the auxiliary track wheel 5 off the auxiliary track 3, and then the four-way vehicle 1 enters the designated cargo position along the main track 2. After that, the main track wheel 6 moves upward to leave the main track 2 and lowers the auxiliary track wheel 5 to contact the auxiliary track 3, the four-way vehicle 1 enters the designated cargo position along the auxiliary track 3, and the lifting plate 7 moves downward to put down the cargo. The four-way vehicle 1 completes one cargo pick-up and placement.

[0045] Embodiment 2

[0046] During its frequent shuttle movement, dust, debris and other debris will inevitably accumulate in the track. The presence of these debris will not only affect the movement stability of the four-way shuttle, but may also cause damage to the equipment itself, thereby reducing its working efficiency and safety. Therefore, it is particularly important to regularly clean and maintain the track. Effective cleaning can ensure that the four-way shuttle runs smoothly on a clean track and reduce failures and accidents caused by track debris. In order to solve such problems, this embodiment 2 is based on the embodiment 1, please refer to Figure 1 and Figure 5 It can be clearly seen that the outer sides of the auxiliary rail wheel 5 and the main rail wheel 6 are respectively provided with cleaning conical wheels 24, and the outer sides of the cleaning conical wheels 24 are provided with a plurality of cleaning ropes 25. When the auxiliary rail wheel 5 and the main rail wheel 6 rotate, the cleaning ropes 25 are synchronously driven to rotate.

[0047] Combination Figure 1 It can be seen that the central axes of the auxiliary rail wheel 5 and the main rail wheel 6 are perpendicular to each other, and it can be seen from the content of Example 1 that during the movement of the four-way vehicle 1, the auxiliary rail wheel 5 and the main rail wheel 6 work selectively. Taking the movement of the auxiliary rail wheel 5 on the auxiliary track 3 as an example, the main rail wheel 6 will not contact the main track 2. Combined with the fact that the auxiliary rail wheel 5 and the main rail wheel 6 always rotate synchronously, when the auxiliary rail wheel 5 moves forward on the auxiliary track 3, the main rail wheel 6 is used to drive the cleaning conical wheel 24 to rotate, so that the cleaning rope 25 cleans the auxiliary track 3, thereby ensuring that the movement stability of the four-way shuttle vehicle will not be affected by the accumulation of debris on the auxiliary track 3.

[0048] Similarly, when the main rail wheel 6 moves on the main rail 2, the auxiliary rail wheel 5 uses the cleaning conical wheel 24 to allow the cleaning rope 25 to clean the main rail 2.

[0049] In actual application, when the main rail wheel 6 is pressed on the main track 2, the cleaning conical wheel 24 on the main rail wheel 6 will not contact the main track 2, thereby avoiding the cleaning rope 25 being placed between the main rail wheel 6 and the main track 2, affecting the driving stability; similarly, the cleaning conical wheel 24 on the auxiliary rail wheel 5 is also relatively far away from the auxiliary track 3.

[0050] In order to ensure that the cleaning rope 25 can rotate circumferentially during the rotation of the cleaning conical wheel 24 driving the cleaning rope 25, a counterweight ball is fixedly connected to the end of the cleaning rope 25. When the cleaning conical wheel 24 rotates, the counterweight ball is forced to be thrown outward, thereby straightening the cleaning rope 25, making it easier to clean the dust on the auxiliary track 3 and the main track 2.

[0051] Embodiment 3

[0052] In order to prevent the cleaning rope 25 from attaching to the outside of the cleaning rope 25 when cleaning the debris, thereby affecting the cleaning effect of the cleaning rope 25 on the track, the third embodiment is further improved on the basis of the second embodiment, please refer to Figure 6 and Figure 7 It can be seen that the cleaning conical wheel 24 is sleeved on the central axis of the auxiliary rail wheel 5 / main rail wheel 6, and a screw is threadedly connected to the central axis of the auxiliary rail wheel 5 / main rail wheel 6, and a reset spring 33 sleeved on the outside of the central axis is arranged between the screw and the cleaning conical wheel 24. Under the elastic force of the reset spring 33, one end of the cleaning conical wheel 24 always has a tendency to push toward the end of the auxiliary rail wheel 5 / main rail wheel 6.

[0053] A rope-binding wheel 32 is movably mounted inside the central axis of the auxiliary rail wheel 5 / main rail wheel 6. Figure 7 It can be seen that one end of the cleaning rope 25 passes through the cleaning conical wheel 24 and is fixedly connected to the rope-binding wheel 32. Since there are multiple cleaning ropes 25, the rope-binding wheel 32 can be connected to multiple cleaning ropes 25 at the same time.

[0054] Combination Figure 1 and Figure 6 It can be seen that a detection pressure wheel 34 is arranged between the auxiliary track wheel 5 and the cleaning cone wheel 24. More specifically, refer to Figure 6 and Fig.12 It can be clearly seen that the outer side of the frame body 14 is fixedly connected to a support frame 141 located above the auxiliary rail wheel 5 / main rail wheel 6, and the top of the support frame 141 is movably installed on the inner side of the detection pressure wheel 34, and the inner side of the detection pressure wheel 34 is provided with an annular groove corresponding to the support frame 141. When the support frame 141 is inserted into the annular groove of the detection pressure wheel 34, the movement of the detection pressure wheel 34 will be limited. At the same time, from Fig.12 As can be seen from the figure, the inner side of the end of the detection pressure wheel 34 is provided with an angle, combined with Figure 6 and Figure 7 It can be seen that the shape of the cleaning cone wheel 24 is a truncated cone. When the cleaning cone wheel 24 is pressed, the inclined angle of the pressure wheel 34 is detected and pressed against the inclined surface of the cleaning cone wheel 24, thereby forcing the cleaning cone wheel 24 to move away from the auxiliary rail wheel 5 / main rail wheel 6. Figure 6 It can be seen that the diameter of the detection pressure wheel 34 is 2-3 times the diameter of the auxiliary rail wheel 5 / main rail wheel 6, thereby ensuring that when the detection pressure wheel 34 moves up and down, only part of the inner side of the detection pressure wheel 34 contacts the auxiliary rail wheel 5 / main rail wheel 6 and the cleaning conical wheel 24.

[0055] In specific application, when the auxiliary rail wheel 5 moves on the auxiliary rail 3, the detection pressure wheel 34 on the auxiliary rail wheel 5 will be pressed and placed between the auxiliary rail wheel 5 and the cleaning cone wheel 24. The cleaning cone wheel 24 is pushed by the detection pressure wheel 34 to move away from the auxiliary rail wheel 5, so that the cleaning cone wheel 24 drives the cleaning rope 25 away from the auxiliary rail wheel 5, avoiding the cleaning cone wheel 24 being placed between the auxiliary rail wheel 5 and the auxiliary rail 3 to affect the stability of the movement of the four-way vehicle 1. When the detection pressure wheel 34 moves upward, the top of the support frame 141 is still on the inner ring of the detection pressure wheel 34. The groove prevents the detection pressure wheel 34 from being separated from the support frame 141. At the same time, when the cleaning conical wheel 24 is pushed away from the auxiliary rail wheel 5, on the one hand, the reset top spring 33 is compressed and stored to provide conditions for the subsequent reset of the cleaning conical wheel 24; on the other hand, since the position of the rope-binding wheel 32 is relatively fixed, when the cleaning conical wheel 24 is pushed outward, the cleaning rope 25 will be forced to be retracted into the cleaning conical wheel 24, and the outer side of the cleaning conical wheel 24 is used to scrape the outer side of the cleaning rope 25, thereby removing the debris attached to the outer side of the cleaning rope 25. Combined with what is said in the second embodiment, since the cleaning conical wheel 24 does not contact the track, the debris on the outer side of the cleaning rope 25 will not fall on the track after being scraped off. At the same time, since the detection pressure wheel 34 on the main rail wheel 6 is not in contact with the main rail 2, the inner ring groove of the detection pressure wheel 34 is pressed on the top of the support frame 141 under the weight of the detection pressure wheel 34 itself, and the detection pressure wheel 34 is relatively far away from the cleaning cone wheel 24. The cleaning cone wheel 24 is pushed toward the main rail wheel 6 under the elastic force of the reset top spring 33, and the cleaning rope 25 is pulled out from the cleaning cone wheel 24 under the traction of the weight ball thrown out. When the main rail wheel 6 moves on the main rail 2, the same as mentioned above.

[0056] It can be seen that in the application of the third embodiment, the intervention of the detection pressure wheel 34 is utilized to achieve the cleaning conical wheel 24 to be further away from the auxiliary rail wheel 5 / main rail wheel 6, thereby ensuring that the cleaning rope 25 on the cleaning conical wheel 24 will not fall between the auxiliary rail wheel 5 / main rail wheel 6 and the rail, thereby ensuring the stability of the movement of the four-way vehicle 1, and when the cleaning conical wheel 24 moves outward, the cleaning conical wheel 24 can scrape the outside of the cleaning rope 25, thereby ensuring that the outside of the cleaning rope 25 is always kept clean, thereby enhancing the cleaning intensity of the rail.

[0057] Embodiment 4

[0058] Further improvements based on the third embodiment, in order to increase the cleaning frequency of the cleaning rope 25 on the track, please refer to Figure 6 and Figure 7It can be seen that a gear ring 26 is provided at one end of the auxiliary rail wheel 5 / main rail wheel 6, and a transmission bevel gear 27 is movably mounted on the support frame 141. On the one hand, the external teeth of the transmission bevel gear 27 and the gear ring 26 are meshed, and on the other hand, the central axis of the transmission bevel gear 27 is perpendicular to the central axis of the auxiliary rail wheel 5 / main rail wheel 6.

[0059] A speed increasing gear 28 is mounted on the rotating shaft of the transmission bevel gear 27, and the speed increasing gear 28 and the transmission bevel gear 27 are coaxially connected. Figure 6 and Figure 7 It can be seen that the diameter of the speed increasing gear 28 is 3-6 times the diameter of the transmission bevel gear 27, and the cleaning cone wheel 24 and the speed increasing gear 28 are meshingly driven. It can be seen that when the auxiliary rail wheel 5 rotates, the transmission bevel gear 27 is forced to rotate synchronously by utilizing the rotation between the ring gear 26 and the transmission bevel gear 27. Since the speed increasing gear 28 is larger in size, when the speed increasing gear 28 rotates, the cleaning cone wheel 24 will be accelerated to rotate.

[0060] In specific implementation, when the auxiliary rail wheel 5 moves on the auxiliary rail 3, the cleaning rope 25 on the auxiliary rail wheel 5 is retracted into the cleaning conical wheel 24, which is the same as the method in Example 3 and will not be described in detail here. When the cleaning conical wheel 24 on the main rail wheel 6 rotates, the main rail wheel 6 rotates the transmission bevel gear 27 through the ring gear 26, and the transmission bevel gear 27 rotates the speed increase gear 28 synchronously. The rotation of the speed increase gear 28 can accelerate the rotation of the cleaning conical wheel 24. When the speed of the cleaning conical wheel 24 increases, the frequency of the cleaning conical wheel 24 driving the cleaning rope 25 to clean the auxiliary rail 3 will also increase, thereby enhancing the cleaning effect on the auxiliary rail 3. When the main rail wheel 6 moves on the main rail 2, the same is true as above.

[0061] It can be seen that the fourth embodiment utilizes the cooperation of the transmission bevel gear 27 and the speed increasing gear 28 to accelerate the rotation of the cleaning conical wheel 24 when the auxiliary rail wheel 5 / the main rail wheel 6 rotates, thereby enhancing the cleaning effect on the rail.

[0062] Embodiment 5

[0063] Further improvements based on the fourth embodiment, refer to Figure 6 and Figure 7The cam 32 is engaged with the guide wheel 32 and the guide wheel 33 is engaged with the guide wheel 34. When the cam 32 is engaged, the guide wheel 33 is engaged with the guide wheel 34 and the guide wheel 33 is engaged with the guide wheel 33. When the cam 32 is engaged, the guide wheel 33 is engaged with the guide wheel 33 and the guide wheel 33 is engaged with the guide wheel 33. The advantage of this method is that the size of the detection pressure wheel 34 can be reduced while ensuring that the cleaning rope 25 is retracted to clean the conical wheel 24, thereby making the device more compact.

[0064] In order to further enhance the cleaning conical wheel 24 to the cleaning rope 25 of the rope length, refer to Figure 7 and Figure 8 It can be known that a slow air chamber 280 is provided inside the speed increasing gear 28. At the same time, a fan blade bar 31 is movably installed on the outer side of the transmission bevel gear 27. Since the top of the fan blade bar 31 is hinged to the outer side of the rotating shaft of the transmission bevel gear 27, when the transmission bevel gear 27 drives the fan blade bar 31 to rotate, Figure 8 For example, when the transmission bevel gear 27 rotates counterclockwise, the fan blade bar 31 will tend to deflect clockwise along the hinge point under the influence of the airflow generated by the rotation, and finally the fan blade bar 31 will tilt on the outside of the transmission bevel gear 27. When the transmission bevel gear 27 continues to rotate, the tilted blades will transport the external airflow downward; similarly, when the transmission bevel gear 27 deflects clockwise, the fan blade bar 31 will deflect counterclockwise, and the airflow will still be transported downward. The number of the fan blade bars 31 is preferably four, to ensure that when the transmission bevel gear 27 drives the fan blade bar 31 to rotate, it can provide sufficient airflow to be input into the slow air chamber 280. Furthermore, the bottom of the rotating shaft of the transmission bevel gear 27 is fixedly connected with a positioning ring 270, and the positioning ring 270 and the speed increasing gear 28 are in a fitting relationship. When the fan blade bar 31 rotates, the downward airflow will pass through the positioning ring 270 and be transported to the slow air chamber 280.

[0065] refer to Figure 7 and Fig. 9 It can be clearly seen that a connecting protrusion 282 is fixedly connected to the inner side of the rotating shaft of the speed increasing gear 28. Fig.10As shown, there are two connecting protrusions 282, and the two connecting protrusions 282 are distributed at 180 degrees. When the connecting protrusion 282 moves upward and between the two blade strips 31, the transmission bevel gear 27 and the speed increasing gear 28 are connected to ensure that the speed increasing gear 28 and the transmission bevel gear 27 can rotate synchronously; similarly, when the connecting protrusion 282 is separated from the blade strip 31, the transmission between the two is no longer performed. More specifically, when the cleaning conical wheel 24 is subjected to the elastic force of the reset top spring 33 and is attached to the end of the auxiliary rail wheel 5 / main rail wheel 6, the outer side of the cleaning conical wheel 24 will push the speed increasing gear 28 upward until the connecting boss 282 goes up to the height of the hinge part between the fan blade bar 31 and the rotating shaft of the transmission bevel gear 27. Since there are two connecting bosses 282, each connecting boss 282 just limits the rotation of two fan blade bars 31. When the transmission bevel gear 27 drives the speed increasing gear 28 to rotate, since the connecting boss 282 is simultaneously pressed against the hinge axis of the fan blade bars 31 on both sides, the fan blade bars 31 are prevented from deflecting, thereby reducing the air flow input into the slow air chamber 280 by the fan blade bar 31 when the cleaning rope 25 cleans the track.

[0066] refer to Fig.11 It can be seen that a plurality of toothed columns 281 are movably mounted on the outer side of the speed-increasing gear 28, and the plurality of toothed columns 281 are arranged at equal angles to form a complete gear. A damping hole 283 for communicating the slow air chamber 280 with the end of the toothed column 281 is provided on the inner side of the speed-increasing gear 28, so that the airflow between the end of the toothed column 281 and the slow air chamber 280 can flow slowly. A one-way valve 284 located on one side of the damping hole 283 is fixedly mounted on the inner side of the speed-increasing gear 28, so that the airflow in the slow air chamber 280 can flow one-way to one end of the toothed column 281 through the one-way valve 284. Correspondingly, reference Figure 7 and Fig. 9 It can be seen that a reset frame 29 is installed on the outside of the speed-increasing gear 28, and the reset frame 29 is fixedly connected to the support frame 141 through a telescopic connecting rod. The shape of the reset frame 29 is fan-shaped. When the tooth column 281 approaches the reset frame 29, the speed-increasing gear 28 blocks the tooth column 281, so that the tooth column 281 can be retracted into the inside of the speed-increasing gear 28, thereby ensuring normal transmission between the speed-increasing gear 28 and the cleaning conical wheel 24.

[0067] In actual application, when the auxiliary rail wheel 5 moves on the auxiliary rail 3, the detection pressure wheel 34 on the auxiliary rail wheel 5 is pressed to push the cleaning cone wheel 24 away from the auxiliary rail wheel 5, and the cleaning cone wheel 24 compresses and accumulates the reset top spring 33. Figure 7It can be seen that when the cleaning cone wheel 24 is away from the auxiliary track wheel 5, the speed increasing gear 28 will move downward under its own weight, and use the outer side of the speed increasing gear 28 to move the adjustment disk 30 closer to the direction away from the cleaning cone wheel 24, and the cleaning rope 25 can be further retracted when the adjustment disk 30 and the cleaning cone wheel 24 are relatively far away. Afterwards, when the connecting protrusion 282 moves downward and completely disengages from the blade bar 31, since the blade bar 31 is still in the inner cavity of the rotating shaft of the speed increasing gear 28, when the gear ring 26 drives the blade bar 31 to rotate faster through the transmission bevel gear 27, the external airflow will be blown into the slow air chamber 280 through the blade bar 31. As the airflow pressure in the slow air chamber 280 increases, the tooth column 281 is forced to extend outward. Since the outer side of the speed increasing gear 28 is now against the cleaning cone wheel 24, when the tooth column 281 is extended, the cleaning cone wheel 24 drives the speed increasing gear 28 to rotate, so that the extended gear train 21 further pushes the adjustment disk 30 to move away from the cleaning cone wheel 24. Since the airflow at the end of the tooth column 281 can only be transported to the slow air chamber 280 through the damping hole 283, the tooth column 281 squeezes the airflow at the end, forcing the tooth column 281 to have enough strength to push the adjustment disk 30 away from the cleaning cone wheel 24, thereby increasing the retracted length of the cleaning rope 25. When the extended tooth column 281 rotates with the speed increasing gear 28, it is blocked by the reset stop frame 29, so that the speed increasing gear 28 can contact the cleaning cone wheel 24 with a fixed extension length. At the same time, the cleaning conical wheel 24 on the main rail wheel 6 will stick to the main rail wheel 6 under the elastic force of the reset top spring 33, thereby using the inclined surface on the outside of the cleaning conical wheel 24 to push the speed-increasing gear 28 to move upward until the connecting boss 282 enters between the fan blades 31, thereby using the connecting boss 282 and the fan blades 31 to connect the transmission bevel gear 27 and the speed-increasing gear 28. When the ring gear 26 drives the transmission bevel gear 27 to rotate, the speed-increasing gear 28 drives the cleaning conical wheel 24 to accelerate the rotation, so that the cleaning rope 25 can clean the track.

[0068] Finally, when the main rail wheel 6 moves on the main rail 2, the same is true as described above.
