Description

Technical Field

[0001] This invention relates to the field of track technology, and more particularly to a shuttle track, a shuttle system, and a broadcast wall. Background Technology

[0002] The automatic distribution wall includes a distribution wall track, a distribution trolley, and a package supply station. The distribution trolley can run automatically on the track to transport items to a designated destination for unloading and distribution.

[0003] In order to enable the trolley to circulate within the track, the track on which the broadcasting vehicle runs is generally designed as a closed design. However, the closed design makes the maintenance and loading of the trolley more troublesome, requiring the track to be disassembled first and then the broadcasting vehicle to be assembled into the track.

[0004] In related technologies, when assembling the track and main body on-site, a gap needs to be left in the track; that is, the track is not fully assembled initially, but completed after the vehicle is mounted. However, during maintenance, the track needs to be disassembled first to facilitate the removal or reassembly of the distribution vehicle. This approach has high implementation and maintenance costs and is difficult to implement.

[0005] In addition, when the broadcasting vehicle is running on the track, it is driven by the interaction of the drive gears on both sides and the rack on the track. During the loading process, the broadcasting vehicle is usually assembled based on experience. If the broadcasting vehicle is not positioned accurately, it is easy to become skewed, which will cause the drive gears to misalign with the rack on the track, resulting in safety hazards and affecting production.

[0006] It should be noted that the information disclosed in the background section of this invention is intended only to enhance the understanding of the overall background of this invention, and should not be construed as an admission or implication in any way that such information constitutes prior art known to those skilled in the art. The foregoing statements are only for providing background information related to this application and do not necessarily constitute prior art. Summary of the Invention

[0066] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0067] In the description of this invention, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this invention.

[0068] refer to Figures 1 to 6 As shown, in some embodiments of the shuttle track provided by the present invention, the shuttle track 10 includes a maintenance track 1, a support track 2, and a positioning part. The maintenance track 1 includes a toothed part 1a, the teeth of which are used to mesh with the teeth of the drive wheel 202 of the shuttle 20 to guide the shuttle 20 to move along the maintenance track 1. The support track 2 is used to support the traveling wheel 203 of the shuttle 20. The positioning part is disposed at the entrance of the support track 2 and is configured to position the traveling wheel 203 so that the teeth of the drive wheel 202 mesh with the teeth of the toothed part 1a at a preset position.

[0069] By setting a positioning unit at the entrance of the support track 2, the traveling wheels 203 of the shuttle 20 can be positioned, thereby positioning the drive wheels 202 of the shuttle 20. This allows the teeth of the drive wheels 202 to mesh with the teeth at preset positions on the maintenance track 1, effectively reducing the occurrence of misaligned teeth, lowering safety hazards, and ensuring the safe operation of the shuttle. Moreover, by positioning the traveling wheels 203 of the shuttle 20 to position the teeth of the drive wheels 202, the positioning unit can avoid the problem of affecting the normal operation of the drive wheels 202 that may occur if the drive wheels 202 are positioned directly.

[0070] When installing the shuttle 20 onto the shuttle track 10, the shuttle 20 can be placed on the shuttle track 10 first, and the positioning part can be used to position the traveling wheel 203 of the shuttle 20, so that the shuttle 20 is placed in a preset position on the shuttle track 10. At this preset position, the teeth of the drive wheel 202 mesh with the corresponding teeth of the tooth part 1a. That is, this preset position is the position that prevents the teeth of the drive wheel 202 on the shuttle 20 from being misaligned. Thus, by positioning the traveling wheel 203, the occurrence of tooth misalignment problem is reduced.

[0071] It should be noted that the positioning unit is located at the entrance of the support track 2. It is easy to understand that this entrance is the entrance through which the shuttle car 20 enters the track when boarding. Of course, when the shuttle car 20 is removed from the track, it is possible that the shuttle car 20 leaves the track through the aforementioned entrance. In this case, the entrance can also be referred to as the exit.

[0072] In the embodiments provided by the present invention, the structural form of the positioning part can be selected in various ways. For example, the positioning part may include a baffle provided on the support rail 2, which positions the traveling wheel 203 by blocking the movement of the traveling wheel 203; the positioning part may also include a hook or adhesive part provided on the support rail 2, which positions the traveling wheel 203 by hooking or adhesively attaching the hook or adhesive part to the shuttle 20, etc.

[0073] like Figures 7 to 9 As shown, in some embodiments, the positioning part includes a groove 21 disposed on the support rail 2, the groove 21 being configured to allow the traveling wheel 203 to be embedded therein or roll out therein.

[0074] By setting the groove 21, when the shuttle 20 is placed on the shuttle track 10, the traveling wheel 203 of the shuttle 20 can be inserted into the groove 21, thereby positioning the traveling wheel 203 and placing the shuttle 20 on the preset position of the shuttle track 10, so that the teeth of the drive wheel 202 mesh with the corresponding teeth of the tooth section 1a, preventing the problem of tooth misalignment.

[0075] The advantage of including the groove 21 in the positioning part is that it can achieve relatively precise positioning of the traveling wheel 203, and after positioning, the traveling wheel 203 can be rolled out of the groove 21 by applying a little force to push the shuttle 20, thereby releasing the positioning effect. Therefore, when using the groove 21 to position the traveling wheel 203, releasing the positioning is also relatively convenient and simple.

[0076] In the embodiments provided by the present invention, the number of positioning parts can be flexibly set as needed, such as one, two or more.

[0077] In some embodiments, the support track 2 includes a first track and a second track arranged side by side, the positioning part includes a first groove disposed on the first track and a second groove disposed on the second track, the shuttle 20 includes a body 201 and a first traveling wheel and a second traveling wheel symmetrically disposed on both sides of the body 201, and the first groove and the second groove are symmetrically arranged with respect to the line of symmetry of the first track and the second track.

[0078] By setting grooves on the first and second tracks respectively, the traveling wheels on both sides of the shuttle 20 body 201 can be embedded into the corresponding grooves, thereby simultaneously limiting both sides of the shuttle 20 and preventing misalignment of the drive wheel teeth on both sides of the shuttle 20. This ensures that the drive wheel teeth on either side of the shuttle 20 mesh with the preset teeth on the track, preventing misalignment of the drive wheel teeth with the mating teeth on the track. It also ensures that the drive wheels on both sides of the shuttle 20 remain symmetrical in the direction perpendicular to the shuttle's travel direction, preventing the shuttle 20 from swaying due to misalignment of the drive wheels on both sides, which would affect the normal operation of the shuttle 20.

[0079] In some embodiments, the maintenance track 1 includes a first maintenance section 11 located at the beginning along the entry direction of the shuttle 20. The first maintenance section 11 is movably disposed relative to the support track 2. The first maintenance section 11 has a first position where the teeth thereon mesh with the teeth of the drive wheel 202, and a second position to prevent interference between the shuttle 20 and the first maintenance section 11 when the shuttle 20 is loaded into the support track 2. The specific location of the second position is flexible and can be any position that will not cause interference between the shuttle 20 and the first maintenance section 11 when the shuttle 20 is loaded into the support track 2.

[0080] By setting a first maintenance section 11 that is movable relative to the support rail 2, when the shuttle 20 is loaded onto the rail, the first maintenance section 11 can be moved to a second position to prevent interference between the shuttle 20 and the first maintenance section 11, and to avoid collision between the first maintenance section 11 and the shuttle 20 during the loading and unloading process. After the shuttle 20 is loaded onto the rail, the first maintenance section 11 can be returned to the first position so that the teeth of the drive wheel 202 of the shuttle 20 can mesh with the teeth on the first maintenance section 11 after loading, so that the shuttle 20 can move under the guidance of the first maintenance section 11.

[0081] There are several options for how the first maintenance section 11 can move relative to the support rail 2. For example, the first maintenance section 11 can move in a straight line or a curved line relative to the support rail 2, or the first maintenance section 11 can be detached from the support rail 2.

[0082] In some embodiments, the shuttle track 10 further includes a mounting member 3, and the maintenance track 1 further includes a first rotating shaft 13, wherein the first maintenance section 11 is rotatably mounted on the mounting member 3 via the first rotating shaft 13.

[0083] In this embodiment, the first maintenance section 11 switches between a first position and a second position by rotating, which saves movement space compared to linear movement and avoids accidental loss of the first maintenance section 11 due to disassembly compared to a detachable method.

[0084] In some embodiments, the shuttle track 10 further includes a mounting member 3, and the maintenance track 1 further includes a first magnet 14 mounted on the mounting member 3, and the first maintenance section 11 is held in a first position by the first magnet 14.

[0085] By setting the first magnet 14, the first maintenance section 11 can be kept in the first position by the first magnet 14, which improves the stability of the first maintenance section 11 in the first position. At the same time, when it is necessary to remove the first maintenance section 11 from the first position, the first maintenance section 11 can also be easily and quickly released from the fixation in the first position.

[0086] In some embodiments, the first magnet 14 may be connected to the end of the first maintenance section 11 that is away from the first rotating shaft 13.

[0087] In some embodiments, the first maintenance segment 11 is shaped such that the first maintenance segment 11 can also be held in a second position by the first magnet 14.

[0088] By constructing the shape of the first maintenance section 11, the first maintenance section 11 can be held in position by the first magnet 14 in the first position, and can also be held in position by the first magnet 14 in the second position.

[0089] For example, such as Figure 10 As shown, the first maintenance section 11 is L-shaped. In the first position, the vertical section of the first maintenance section 11 is magnetically connected to the first magnet 14, so that the first maintenance section 11 can be maintained in the first position, thus achieving stability of the first maintenance section 11 in the first position. In the second position, the horizontal section of the first maintenance section 11 is magnetically connected to the first magnet 14, so that the first maintenance section 11 can be maintained in the second position, thus achieving stability of the first maintenance section 11 in the second position.

[0090] Of course, in other embodiments, the first maintenance segment 11 can also be of other shapes, as long as the first maintenance segment 11 can contact the first magnet 14 and be connected by magnetic force in both the first position and the second position.

[0091] In some embodiments, the maintenance track 1 further includes a handle 15 mounted on the first maintenance section 11. By providing the handle 15, it is convenient for personnel to grip, and when switching the position of the first maintenance section 11, personnel can hold the handle 15 to drive the first maintenance section 11 to rotate around the first rotating shaft 13.

[0092] In some embodiments, the shuttle track 10 further includes a first guide track 4 and a second guide track 5 for guiding the movement of the shuttle 20. The first guide track 4 is connected to the maintenance track 1, and the extension direction of the first guide track 4 is the same as the guidance direction of the maintenance track 1, while the extension direction of the second guide track 5 is different from the guidance direction of the maintenance track 1.

[0093] The first guide track 4 and the second guide track 5 are the main tracks of the shuttle car track 10. During the movement of the items, the shuttle car 20 mainly moves along the first guide track 4 and the second guide track 5.

[0094] In some embodiments, the first guide rail 4 extends horizontally, and the second guide rail 5 extends vertically. The shuttle 20 moves laterally along the first guide rail 4 and moves vertically along the second guide rail 5.

[0095] In some embodiments, the maintenance track 1 includes a first maintenance section 11 located at the beginning along the direction of entry of the shuttle 20 and a second maintenance section 12 located downstream of the first maintenance section 11. The second maintenance section 12 has a third position that disconnects the first maintenance section 11 and the first guide track 4 and a fourth position that connects the first maintenance section 11 and the first guide track 4.

[0096] By setting a second maintenance section 12 with a third and a fourth position, the connection or disconnection of the first maintenance section 11 and the first guide rail 4 can be achieved by switching the position of the second maintenance section 12. When the first maintenance section 11 and the first guide rail 4 are connected through the second maintenance section 12, the connection channel between the track and the outside world can be opened, allowing the shuttle 20 to enter the first guide rail 4 through the maintenance rail 1 or leave the track from the first guide rail 4 through the maintenance rail 1, thus realizing the boarding or alighting of the shuttle 20. When the first maintenance section 11 and the first guide rail 4 are disconnected, the connection channel between the track and the outside world is closed, and the shuttle 20 can switch between the first guide rail 4 and the second guide rail 5.

[0097] There are several ways to achieve the position switching of the second maintenance section 12 between the third and fourth positions. For example, the second maintenance section 12 can switch between the third and fourth positions through linear or curvilinear movement, or it can be detachably configured to achieve the position switching.

[0098] In some embodiments, the shuttle track 10 further includes a mounting member 3, and the maintenance track 1 further includes a second rotating shaft 16, wherein the second maintenance section 12 is rotatably mounted on the mounting member 3 via the second rotating shaft 16.

[0099] By setting a second rotating shaft 16, the second maintenance section 12 can rotate around the second rotating shaft 16, and the second maintenance section 12 can switch between the third position and the fourth position by rotating.

[0100] In some embodiments, the maintenance track 1 further includes a connecting assembly 17, a second rotating shaft 16 is rotatably mounted on the mounting member 3, a second maintenance section 12 is fixedly connected to the second rotating shaft 16, the connecting assembly 17 is connected between the second rotating shaft 16 and the mounting member 3, and the connecting assembly 17 is configured to allow the second maintenance section 12 to be selectively held in a third position or in a fourth position.

[0101] By setting the connecting component 17, the second maintenance section 12 can be kept in the third position when it moves to the third position, and it can also be kept in the fourth position when it moves to the fourth position, so as to maintain the stability of the second maintenance section 12 in the third and fourth positions.

[0102] like Figure 12As shown, in some embodiments, the connecting assembly 17 includes a connecting rod 171, an elastic element 172, and a fixing element 173. The fixing element 173 is fixedly installed on the mounting element 3. The connecting rod 171 is fixedly connected to the second rotating shaft 16. The elastic element 172 is connected between the connecting rod 171 and the fixing element 173. When the second maintenance section 12 rotates around the axis of the second rotating shaft 16, it drives the connecting rod 171 to rotate through the second rotating shaft 16. When the line connecting the connection point of the connecting rod 171 and the elastic element 172 and the connection point of the connecting rod 171 and the second rotating shaft 16 is collinear with the extension direction of the elastic element 172, the connecting assembly 17 and the second maintenance section 12 are in a state of force balance.

[0103] The elastic element 172 can be made of elastic components such as springs or rubber.

[0104] By setting the fixing member 173, one end of the elastic member 172 can be fixed relative to the mounting member 3.

[0105] The structure of the fastener 173 can be flexibly configured. For example, the fastener 173 may include a screw, the nail part of which is mounted on the mounting part 3, and one end of the elastic member 172 is fitted onto the end of the nail part and limited by the head of the screw.

[0106] The fastener 173 can be a connecting part on the mounting part 3 and integrally formed with the mounting part 3.

[0107] The connecting rod 171 is fixedly connected to the second rotating shaft 16. When the second maintenance section 12 rotates around the axis of the second rotating shaft 16, the second maintenance section 12 will drive the second rotating shaft 16 to move relative to the mounting part 3. The second rotating shaft 16 will then drive the connecting rod 171 to rotate, and the connecting rod 171 will pull the elastic element 172 to deform.

[0108] like Figure 13 As shown, the line connecting the connection point of the connecting rod 171 and the elastic element 172 and the connection point of the connecting rod 171 and the second rotating shaft 16 is collinear with the extension direction of the elastic element 172. At this time, the connecting assembly 17 and the second maintenance section 12 are in a state of force balance, and the elastic element 172 is in a state of natural extension, that is, the elastic element 172 is neither stretched nor compressed, and at this time the second maintenance section 12 is located between the third position and the fourth position.

[0109] like Figure 14 As shown, when the second maintenance section 12 moves to the third position, the elastic element 172 is located on the side that prevents the connecting rod 171 from returning to the equilibrium position. The elastic force of the elastic element 172 can keep the second maintenance section 12 in the third position and maintain the stability of the second maintenance section 12 in the third position.

[0110] like Figure 15As shown, when the second maintenance section 12 moves to the fourth position, the elastic element 172 is located on the side that prevents the connecting rod 171 from returning to the equilibrium position. The elastic force of the elastic element 172 can keep the second maintenance section 12 in the fourth position and maintain the stability of the second maintenance section 12 in the fourth position.

[0111] In some embodiments, the maintenance track 1 further includes a support member 18, which is configured to support the second maintenance section 12 when the second maintenance section 12 is in the third position, and the support member 18 is provided with a limiting groove 181 for limiting the second maintenance section 12.

[0112] By providing the support member 18, the second maintenance section 12 can be supported when it is in the third position, and it can also be limited to prevent the second maintenance section 12 from continuing to move clockwise and moving further away from the equilibrium position. By providing the limiting groove 181, the second maintenance section 12 can be confined in the limiting groove 181, further improving the stability of the second maintenance section 12.

[0113] The end of the second maintenance section 12 away from the second rotating shaft 16 is triangular in shape. Correspondingly, the limiting groove 181 is also set in a triangular shape so that the second maintenance section 12 will not be subjected to collision or wear when it is embedded in the limiting groove 181.

[0114] In some embodiments, the support member 18 may be installed on the back side of the support surface of the support rail 2 so as not to affect the support rail 2 for the shuttle 20.

[0115] In some embodiments, a through hole 27 may be provided on the support surface of the support rail 2 so that the head of the second maintenance section 12 can pass through the through hole 27 and enter the limiting groove 181 of the support member 18, without affecting the support of the support rail 2 on the shuttle 20.

[0116] In some embodiments, there is a preset distance between the through hole 27 and the edge of the support surface of the support rail 2 to prevent the walking wheel 203 from falling into the through hole 27 and to avoid the through hole 27 affecting the normal walking of the walking wheel 203.

[0117] In some embodiments, the maintenance track 1 further includes a buffer pad 19 disposed on the sidewall of the limiting groove 181 to buffer the second maintenance section 12.

[0118] By setting the buffer pad 19, the second maintenance section 12 can be buffered when it enters the limiting groove 181, preventing the second maintenance section 12 from colliding with the side wall of the limiting groove 181 when it enters the limiting groove 181 and causing damage to the second maintenance section 12. It also helps to protect the support member 18.

[0119] Furthermore, the buffer pad 19 can be disposed on one side of the tooth of the second maintenance section 12 supporting the limiting groove 181 to protect the tooth from damage.

[0120] In some embodiments, the shuttle track 10 further includes an auxiliary track 6 for cooperating with the upper guide wheel 204 of the shuttle 20. The auxiliary track 6 is configured to guide the shuttle 20 to switch between the first guide track 4 and the second guide track 5, and to guide the shuttle 20 to enter or leave the first guide track 4.

[0121] By setting up the auxiliary track 6, the shuttle 20 can be guided to switch between the first guide track 4 and the second guide track 5; at the same time, the auxiliary track 6 is also configured to guide the shuttle 20 into or out of the first guide track 4. Therefore, this embodiment of the invention, through modification of the auxiliary track 6, enables the auxiliary track 6, which already has the function of guiding the shuttle 20 to switch between the first guide track 4 and the second guide track 5, to also have the function of guiding the shuttle 20 into or out of the first guide track 4.

[0122] like Figures 10 to 12 As shown, in some embodiments, the auxiliary track 6 includes a first mating part 61 and a second mating part 62. The first mating part 61 is arc-shaped, and the extension direction of the second mating part 62 is parallel to the extension direction of the first guide track 4.

[0123] By providing a second mating part 62 whose extension direction is parallel to that of the first guide rail 4, the shuttle car 20 can enter or leave the first guide rail 4 under the guidance of the second mating part 62.

[0124] In some embodiments, the auxiliary track 6 further includes a sealing plate 63, and a first channel 64 is formed between the first mating part 61 and the second mating part 62, which allows the upper guide wheel 204 to move along the first mating part 61. The sealing plate 63 has a first state of blocking the first channel 64 and a second state of allowing the first channel 64 to be unobstructed.

[0125] By setting the sealing plate 63, the first channel 64 can be selectively blocked. When the sealing plate 63 is in the first state, the sealing plate 63 blocks the first channel 64, and the upper guide wheel 204 of the shuttle 20 cannot pass through the first channel 64. At this time, the auxiliary rail 6 is used to guide the shuttle 20 to switch between the first guide rail 4 and the second guide rail 5. When the sealing plate 63 is in the second state, the sealing plate 63 leaves the first channel 64, and the first channel 64 is unobstructed. The upper guide wheel 204 of the shuttle 20 can pass through the first channel 64. At this time, the auxiliary rail 6 is used to guide the movement of the shuttle 20 during the process of getting on and off the shuttle 20.

[0126] In some embodiments, the sealing plate 63 includes an arcuate portion, which forms a second channel 67 with the first mating portion 61. The upper guide wheel 204 moves along the second channel 67 to guide the shuttle 20 to switch between the first guide track 4 and the second guide track 5.

[0127] By setting a sealing plate 63 including an arc-shaped part, when the sealing plate 63 is blocked in the first channel 64, it can both prevent the upper guide wheel 204 from moving along the first channel 64 and form a second channel 67 with the first mating part 61 to guide the movement of the upper guide wheel 204. At this time, the shuttle car 20 can switch between the first guide track 4 and the second guide track 5.

[0128] In some embodiments, the shuttle track 10 further includes a mounting member 3, the auxiliary track 6 further includes a second magnet 65 mounted on the mounting member 3, the first mating part 61 and the second mating part 62 are both mounted on the mounting member 3, and the sealing plate 63 is mounted on the mounting member 3 by the second magnet 65.

[0129] By setting the second magnet 65, the sealing plate 63 can be detachably installed in the first channel 64 of the mounting piece 3, and installation and removal are very convenient.

[0130] In some embodiments, the shuttle track 10 further includes a pressure plate 7 mounted on the support track 2. When the shuttle 20 moves on the first support surface of the support track 2, the pressure plate 7 is located above the lower guide wheel 205 of the shuttle 20 to prevent the shuttle 20 from tipping over.

[0131] The first support surface of the supporting track 2 can be the support surface of the traveling wheels 203 of the shuttle 20, i.e., as shown in the figure. Figure 11 The upper surface of the first support portion 22 shown.

[0132] By setting the pressure plate 7, the lower guide wheel 205 can move below the pressure plate 7 during the movement of the shuttle 20, thus guiding the movement of the lower guide wheel 205. At the same time, under the restriction of the lower guide wheel 205 by the pressure plate 7, the shuttle 20 can also be prevented from tipping over, ensuring the stability of the shuttle 20 during movement. In addition, during the process of getting on or off the shuttle, the restriction of the pressure plate 7 can also eliminate the need for personnel to hold the shuttle 20, effectively reducing the burden on workers and preventing accidental risks.

[0133] like Figure 11As shown, in some embodiments, the shuttle track 10 further includes an inclined plate 70 installed at the end of the pressure plate 7, the inclined plate 70 extending from the position connected to the pressure plate 7 in a direction away from the first support surface of the support track 2. This allows the distance between the inclined plate 70 and the first support surface of the support track 2 to be greater than the distance between the pressure plate 7 and the first support surface of the support track 2, thereby making it easier for the lower guide wheel 205 of the shuttle 20 to enter the guide channel formed by the pressure plate 7 and the support track 2.

[0134] Based on the shuttle track 10 described above, the present invention also proposes a shuttle system, which includes a shuttle 20 and the shuttle track 10 described above.

[0135] Based on the shuttle system described above, the present invention also proposes a broadcast wall 100, which includes the shuttle system described above.

[0136] The shuttle system provided in this embodiment of the invention can also be applied to sorting systems or bin storage and retrieval systems for transporting goods or bins.

[0137] The positive technical effects of the shuttle tracks in the above embodiments are also applicable to the shuttle system and the broadcast wall, and will not be repeated here.

[0138] The following is in conjunction with the appendix Figures 1 to 21 The structure and operation of one embodiment of the shuttle track, shuttle system, and broadcast wall of the present invention will be described:

[0139] like Figure 1 As shown, the broadcast wall 100 includes a shuttle track 10, a shuttle 20, a package supply station 30, and a storage box 40.

[0140] The horizontal section of the shuttle track 10 has multiple layers along the vertical direction, with tracks for ascending and tracks for descending set on the left and right sides respectively.

[0141] The shuttle 20 runs on the shuttle track 10 to transport goods to pre-set storage boxes 40. Multiple storage boxes 40 are arranged on the front side of each track that extends laterally.

[0142] The supply platform 30 is connected to the transverse part of the shuttle track 10. The goods are transported by the supply platform 30 to the shuttle 20 located on the shuttle track 10, and are then taken to the preset storage box 40 by the shuttle 20.

[0143] like Figure 2 and Figure 3 As shown, the shuttle 20 runs on the shuttle track 10 and moves laterally and vertically along the shuttle track 10.

[0144] like Figure 4 and Figure 5 As shown, the shuttle 20 includes a body 201, drive wheels 202, traveling wheels 203, upper guide wheels 204, lower guide wheels 205, sidewalls 206, and inner guide wheels 207. The outer circumference of the traveling wheels 203 is typically covered with wear-resistant materials such as rubber to improve their wear resistance; the traveling wheels 203 can be referred to as rubber-coated wheels.

[0145] The drive wheel 202 is located at the bottom center of the vehicle body 201, and the travel wheel 203 is located inside the drive wheel 202. A flange 206 is provided on the side of the travel wheel 203 away from the drive wheel 202; the diameter of the flange 206 is larger than the diameter of the travel wheel 203, which in turn is larger than the diameter of the drive wheel 202. The outer circumference of the drive wheel 202 has teeth. The outer circumference of the travel wheel 203 is smooth. The drive wheel 202 and the travel wheel 203 are coaxial.

[0146] The upper guide wheel 204 is located above the lower guide wheel 205, and the inner guide wheel 207 is located inside the lower guide wheel 205.

[0147] The rotation axes of the drive wheel 202, the traveling wheel 203, the upper guide wheel 204, and the lower guide wheel 205 are parallel. The rotation axis of the inner guide wheel 207 is perpendicular to the rotation axes of the drive wheel 202, the traveling wheel 203, the upper guide wheel 204, and the lower guide wheel 205.

[0148] The vehicle body 201 has a drive wheel 202, a travel wheel 203, two upper guide wheels 204, two lower guide wheels 205 and two inner guide wheels 207 on each side.

[0149] like Figure 6 As shown, the shuttle track 10 includes a maintenance track 1, a support track 2, an installation component 3, a first guide track 4, a second guide track 5, an auxiliary track 6, and a pressure plate 7.

[0150] The maintenance track 1 includes a toothed section 1a, which has teeth for meshing with the teeth of the drive wheel 202 of the shuttle 20.

[0151] Maintenance rail 1, support rail 2, and auxiliary rail 6 are all installed on mounting component 3. Pressure plate 7 is installed on support rail 2.

[0152] The first guide rail 4 extends horizontally, and the second guide rail 5 extends vertically.

[0153] like Figures 7 to 9 As shown, the maintenance track 1 includes a first maintenance section 11 and a second maintenance section 12, and the toothed part 1a includes teeth disposed on the first maintenance section 11 and teeth disposed on the second maintenance section 12.

[0154] Support rail 2 is used to support the traveling wheels 203 and lower guide wheels 205 of shuttle 20. Auxiliary rail 6 is used to guide the upper guide wheels 204 of shuttle 20.

[0155] like Figure 10 As shown, the first maintenance section 11 is generally L-shaped. One end of the first maintenance section 11 is rotatably connected to the mounting component 3 via a first rotating shaft 13, and the other end is fixed to the mounting component 3 via a first magnet 14. A handle 15 is connected to the first maintenance section 11, allowing personnel to hold the handle 15 and rotate the first maintenance section 11 relative to the mounting component 3 around the first rotating shaft 13, thereby switching the first maintenance section 11 between a first position and a second position.

[0156] like Figure 11 and Figure 12 As shown, one end of the second maintenance section 12 is rotatably mounted on the mounting member 3 via a second rotating shaft 16. The second maintenance section 12 is fixedly connected to the second rotating shaft 16, which is rotatable relative to the mounting member 3. A connecting assembly 17 is also connected between the second rotating shaft 16 and the mounting member 3.

[0157] The connecting assembly 17 includes a connecting rod 171, an elastic element 172, and a fixing element 173. The connecting rod 171 is fixedly connected to the second rotating shaft 16. When the second maintenance section 12 rotates relative to the mounting member 3, the second rotating shaft 16 rotates with the second maintenance section 12, driving the connecting rod 171 to rotate. The fixing element 173 is fixedly installed on the mounting member 3, and the elastic element 172 is connected between the connecting rod 171 and the fixing element 173. When the connecting rod 171 rotates with the second rotating shaft 16, the connecting rod 171 pulls the elastic element 172 to deform.

[0158] The end of the second maintenance section 12 furthest from the second rotating shaft 16 is triangular in shape.

[0159] The second maintenance section 12 has a third position that disconnects the first maintenance section 11 from the first guide rail 4 and a fourth position that connects the first maintenance section 11 to the first guide rail 4.

[0160] When the first maintenance section 11 is connected to the first guide rail 4, the teeth of the first maintenance section 11, the second maintenance section 12 and the first guide rail 4 are continuous.

[0161] like Figure 13 As shown, the second maintenance section 12 is located between the third and fourth positions. However, at this time, the extension direction of the connecting rod 171 and the extension direction of the elastic element 172 are collinear. At this time, the connecting rod 171 and the elastic element 172 are in a state of force balance, and the elastic element 172 is in a state of natural extension.

[0162] like Figure 14As shown, the second maintenance section 12 is in the third position, at which point the end of the second maintenance section 12 away from the second rotating shaft 16 is embedded in the limiting groove 181 of the support member 18. Moreover, the side wall of the limiting groove 181 is provided with a buffer pad 19, which can protect the teeth on the second maintenance section 12.

[0163] The support member 18 is installed on the back of the support surface of the first support part 22. The first support part 22 is also provided with a through hole 27 so that the second maintenance section 12 can pass through the through hole 27 and enter the limiting groove 181. At this time, the channel between the first maintenance section 11 and the first guide rail 4 is fully open. The shuttle 20 moving along the first guide rail 4 cannot get off or get on through the first maintenance section 11. However, the shuttle 20 can switch between the first guide rail 4 and the second guide rail 5.

[0164] When the second maintenance section 12 is in the third position, the elastic element 172 is located on the side that prevents the connecting rod 171 from returning to the equilibrium position. The elastic force of the elastic element 172 can keep the second maintenance section 12 in the third position and maintain the stability of the second maintenance section 12 in the third position.

[0165] like Figure 15 As shown, the second maintenance section 12 is in the fourth position. The first maintenance section 11 and the first guide rail 4 are connected through the second maintenance section 12. At this time, due to the obstruction of the second maintenance section 12, the shuttle car 20 cannot switch between the first guide rail 4 and the second guide rail 5. However, the shuttle car 20 can get on or off through the first maintenance section 11.

[0166] When the second maintenance section 12 is in the fourth position, the elastic element 172 is located on the side that prevents the connecting rod 171 from returning to the equilibrium position. The elastic force of the elastic element 172 can keep the second maintenance section 12 in the fourth position and maintain the stability of the second maintenance section 12 in the fourth position.

[0167] like Figure 11 As shown, the support rail 2 is a sheet metal part with multiple bends. The support rail 2 includes a first support part 22, a second support part 23, a first connecting part 24, a second connecting part 25, and a guide part 26.

[0168] The first support portion 22 and the second support portion 23 are parallel to the horizontal plane. A first connecting portion 24 connects the first support portion 22 and the second support portion 23. A second connecting portion 25 connects to the first support portion 22. The second connecting portion 25 has multiple connecting holes for connection with the mounting member 3. A guide portion 26 connects to the side of the second support portion 23 away from the first connecting portion 24. The guide portion 26 is perpendicular to the horizontal plane.

[0169] The first support part 22 has a groove 21 at its entrance end. When the shuttle 20 is placed on the support track 2, the traveling wheel 203 is embedded in the groove 21.

[0170] like Figure 8 As shown, the first support part 22 is used to support the walking wheel 203, the second support part 23 is used to support the lower guide wheel 205, and the guide part 26 is used to restrict and guide the inner guide wheel 207.

[0171] The first connecting part 24 is also perpendicular to the horizontal plane. The first connecting part 24 is used to contact the guard edge 206 on the running wheel 203 of the shuttle 20, so as to limit the lateral position of the shuttle 20 by limiting the guard edge 206.

[0172] like Figure 16 As shown in Figures 1 and 2, a groove 21 for limiting the travel wheel 203 is provided near the end of the first support 22, while a through hole 27 for allowing the second maintenance section 12 to pass through and enter the limiting groove 181 of the support 18 is provided at a position of the first support 22 corresponding to the second maintenance section 12, which is located approximately near the middle position.

[0173] Furthermore, the groove 21 is located at the edge of the first support portion 22, that is, near the edge of the first connecting portion 24, to ensure that the walking wheel 203 can be inserted into the groove 21 and to prevent the groove 21 from losing its positioning function for the walking wheel 203; and there is a preset distance between the through hole 27 and the edge of the first support portion 22, which can prevent the walking wheel 203 from falling into the through hole 27 and affecting the normal walking of the walking wheel 203.

[0174] The pressure plate 7 is an L-shaped plate, installed on the first connecting part 24. The pressure plate 7 is located above the lower guide wheel 205 and is used to prevent the shuttle car 20 from tipping over, while also eliminating the need for personnel to hold it and reducing their burden. Inclined plates are installed at both ends of the pressure plate 7, and the distance between the inclined plates and the second support part 23 is greater than the distance between the pressure plate 7 and the second support part 23.

[0175] like Figure 10 and Figure 11 As shown, the auxiliary track 6 includes a first mating part 61, a second mating part 62, a sealing plate 63, a first channel 64, a second magnet 65, a limiting part 66, a second channel 67, and a base plate 68.

[0176] The first mating part 61 is arc-shaped. The second mating part 62 extends horizontally. A first horizontally extending channel 64 is formed between the first mating part 61 and the second mating part 62. The limiting part 66 extends vertically, and an extension of the second channel 67 is formed between the first mating part 61 and the limiting part 66.

[0177] The first mating part 61 and the second mating part 62 are connected by the base plate 68. The first mating part 61, the second mating part 62, the limiting part 66 and the base plate 68 can be integrally formed, and the whole assembly consisting of the first mating part 61, the second mating part 62, the limiting part 66 and the base plate 68 is installed on the mounting part 3.

[0178] The sealing plate 63 is disposed in the first channel 64, and the sealing plate 63 is detachably mounted on the base plate 68 by means of the second magnet 65.

[0179] The sealing plate 63 includes an arc-shaped portion, which forms a second channel 67 with the first mating portion 61. The sealing plate 63 also includes a square portion, which is similar in shape to the first channel 64. When the sealing plate 63 is installed in the first channel 64, the square portion fills the first channel 64, thus forming a blocking effect.

[0180] When the sealing plate 63 leaves the first channel 64, the extension of the second channel 67 is connected to the first channel 64.

[0181] When the sealing plate 63 is in the first state and the sealing plate 63 is installed in the first channel 64, after the upper guide wheel 204 of the shuttle 20 enters the first channel 64 from the left, although it cannot continue to move along the first channel 64 due to the obstruction of the sealing plate 63, it can continue to move along the second channel 67 and enter the extension section of the second channel 67, thereby realizing the switch from the first guide track 4 to the second guide track 5.

[0182] When the sealing plate 63 is in the second state, the sealing plate 63 leaves the first channel 64, and the upper guide wheel 204 of the shuttle 20 can enter or leave the track along the first channel 64 to realize the boarding or disembarking of the shuttle 20.

[0183] After the shuttle 20 has fully entered the first guide track 4, the upper guide wheel 204 is suspended in the air.

[0184] The following is in conjunction with the appendix Figures 17 to 21 Introducing the boarding process for Shuttle 20:

[0185] like Figure 17 As shown, before boarding, the first maintenance section 11 of maintenance track 1 is in the first position, the second maintenance section 12 is in the third position, and the first guide track 4 is disconnected from the first maintenance section 11. The sealing plate 63 on the auxiliary track 6 is in the first state, and the auxiliary track 6 is used to guide the shuttle 20 to switch between the first guide track 4 and the second guide track 5.

[0186] like Figure 18 As shown, before boarding, personnel manually rotate the second maintenance section 12 to the fourth position, so that the first guide rail 4 is connected to the first maintenance section 11.

[0187] At the same time, personnel need to manually hold handle 15 to rotate the first maintenance section 11 to the second position so that the shuttle 20 can be placed on the support rail 2 to prevent the first maintenance section 11 from interfering with the shuttle 20.

[0188] In addition, the sealing plate 63 needs to be removed from the first channel 64 so that the upper guide wheel 204 of the shuttle 20 can enter the first channel 64.

[0189] Moreover, such as Figure 19 and Figure 20 As shown, after the shuttle 20 is placed on the support rail 2, the first maintenance section 11 needs to be manually returned to the first position so that the teeth of the drive wheel 202 of the shuttle 20 mesh with the teeth on the first maintenance section 11.

[0190] Meanwhile, when the shuttle 20 is placed on the support rail 2, the running wheels 203 on the left and right sides of the shuttle 20 are respectively embedded into the corresponding grooves 21 of the support rail 2 to position the shuttle 20 and prevent misalignment. In addition, the lower guide wheel 205 of the shuttle 20 contacts the second support part 23 of the support rail 2, the flange 206 is pressed against the first connecting part 24, and the inner guide wheel 207 contacts the guide part 26.

[0191] like Figure 21 As shown, after the teeth of the drive wheel 202 of the shuttle 20 mesh with the teeth on the first maintenance section 11, the shuttle 20 is pushed to move along the first maintenance section 11, and then along the second maintenance section 12 until it moves to the first guide track 4.

[0192] After the shuttle 20 has fully entered the first guide rail 4, the second maintenance section 12 can be returned to the third position, disconnecting the connection between the first guide rail 4 and the first maintenance section 11, so that the shuttle 20 can switch from the first guide rail 4 to the second guide rail 5, thereby achieving the ascent of the shuttle 20.

[0193] The shuttle track provided in this embodiment of the invention enables the shuttle to smoothly connect with the first guide track after boarding, preventing misalignment.

[0194] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the present invention or equivalent substitutions can still be made to some technical features without departing from the principle of the present invention, and such modifications and equivalent substitutions should all be covered within the scope of the technical solutions claimed in the present invention.
