[0057] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field based on the present invention are within the scope of protection of the present invention.

[0058] As mentioned in the background art, in related art, storage devices generally include shelves, on which handling robots are installed to carry boxes on the shelves. Since the handling robots are installed on the shelves, the shelves bear a high load, so the load-bearing capacity of the shelves is required to be high.

[0059] In order to reduce the load on the shelf, the present invention provides a transport robot and a storage device. Figure 1a and Figure 1b , Figure 1a This is a three-dimensional structural diagram of a storage device according to an embodiment of the present utility model; Figure 1b for Figure 1a A front view of the storage unit is shown.

[0060] like Figure 1a and Figure 1b As shown, the storage device provided by the embodiment of the present invention includes shelves 100 and a transport robot 200, and aisles are formed between adjacent shelves 100. The transport robot 200 provided by the embodiment of the present invention is described in detail below.

[0061] See also Figures 2a to 2c , Figure 2a for Figure 1a The three-dimensional structure diagram of the handling robot shown; Figure 2b for Figure 1a A three-dimensional structural diagram of the transport robot (not shown the material box pick-up and placement component) and the horizontal track; Figure 2c for Figure 1a The three-dimensional structure diagram of the transport robot (not shown the material box pick-up and placement components) and the horizontal track from another angle. Figures 1a to 2c As shown,

[0062] The transport robot 200 is hung on the first shelf 100A located on one side of the aisle; the transport robot 200 includes: a support frame 210, a material box picking and placing component 220 and a ground walking mechanism 230; the support frame 210 can move horizontally on the side of the first shelf 100A; the material box picking and placing component 220 can be raised and lowered relative to the support frame 210, and pick up and place the material boxes; the ground walking mechanism 230 is arranged at the bottom of the support frame 210, located on the side of the aisle close to the first shelf 100A, and is used to cooperate with the ground to provide support force and walking power for the transport robot 200.

[0063] Specifically, the adjacent shelves 100 include a first shelf 100A and a second shelf (not shown in the figure), and an aisle is formed between the first shelf 100A and the second shelf for the transport robot 200 to move horizontally in the aisle near the side of the first shelf 100A to pick up and place the boxes on the first shelf 100A and / or the second shelf.

[0064] Figure 2a The unshown portion of the transport robot 200 is the support frame 210, the height of which is determined by the height of the shelf 100. The support frame 210 may have a variety of structures, including a single column or a column gantry consisting of two columns, which is not limited in the present invention.

[0065] The material box picking and placing assembly 220 can also be horizontally extended and retracted relative to the support frame 210 to pick up and place material boxes on adjacent shelves 100 on both sides of the aisle.

[0066] In the specific embodiment provided by the present invention, the support frame 210 is a column gantry, including two oppositely arranged columns 210a. The material box pick-up and placement assembly 220 may include two sliding connectors 221, a pick-up and placement platform 222, and a telescopic mechanism (not shown in the figure). The pick-up and placement platform 222 is used to carry the material box and is arranged between the two columns 210a of the support frame 210. The two sides are slidably connected to the columns 210a via a sliding connector 221, and can be raised and lowered along the support frame 210 to pick up and place material boxes of different heights on the shelf 100. The pick-up and placement platform 222 can also be driven by the telescopic mechanism to extend toward the first shelf 100A or the second shelf on both sides of the lane to pick up and place material boxes on these two shelves 100.

[0067] The transport robot and storage device provided by the present invention are characterized by a transport robot 200 mounted on a first shelf 100A located on one side of an aisle via a support frame 210 and capable of sliding horizontally along shelf 100. A ground running mechanism 230 is located on the side of the aisle near first shelf 100A and is configured to engage in rolling contact with the ground surface on which shelf 100 rests, providing support and driving force for the transport robot 200. A portion of the weight of the transport robot 200 is applied to the ground via the ground running mechanism 230, reducing the load on shelf 100 and, therefore, the load-bearing capacity requirements for shelf 100.

[0068] In some embodiments of the present invention, Figure 1a and Figure 1b As shown, a plurality of horizontal rails 300 are fixedly provided on the outside of the shelf 100. The plurality of horizontal rails 300 are arranged at intervals along the vertical direction of the shelf 100. The transport robot 200 is hung on the first shelf 100 via the plurality of horizontal rails 300.

[0069] Specifically, the support frame 210 is vertically mounted on multiple horizontal rails 300 and is movably connected to the first shelf 100A in the horizontal direction. The transport robot 200 is hung on the first shelf 100A located on one side of the lane via the multiple horizontal rails 300 and moves horizontally along the shelf 100 based on the multiple horizontal rails 300.

[0070] In a specific embodiment of the present invention, Figure 2b As shown, two upper and lower horizontal rails 300 are fixed to the outside of the first shelf 100A. The horizontal rails 300 are provided with grooves 310 extending in the horizontal direction. The support frame 210 is suspended and installed on the horizontal rails 300 through the grooves 310.

[0071] By applying the embodiment of the present invention, the transport robot 200 can be hung on the first shelf 100A located on one side of the aisle based on the horizontal track 300, and move horizontally in the length direction of the shelf 100 to pick up and place various material boxes in the length direction of the shelf 100.

[0072] In some embodiments of the present invention, Figures 2a to 2c As shown, the ground walking mechanism 230 includes: a driving component 231 arranged at the bottom of the support frame 210, and the driving component 231 is used for rolling contact with the ground to support and drive the support frame 210 to move horizontally along the shelf 100 on the ground.

[0073] The ground walking mechanism 230 further includes a mounting assembly 232 ; the mounting assembly 232 is fixedly connected to the bottom of the support frame 210 or movably connected in the vertical direction, and the driving assembly 231 is disposed on the mounting assembly 232 .

[0074] By applying the embodiment of the present utility model, the transport robot 200 is installed and hung on the horizontal track 300, so that part of its weight is applied to the first shelf 100A, and the other part of its weight is applied to the ground through the drive component 231 that is in rolling contact with the ground, thereby reducing the load borne by the first shelf 100A. In addition, by providing the drive component 231, the ground walking mechanism 230 has a driving function. Part of the driving force that drives the transport robot 200 to move horizontally comes from the movement of the drive component 231 relative to the ground, making the movement of the transport robot 200 more stable; the other part of the driving force comes from the side shift drive mechanism 260 of the transport robot 200, which will be described in detail later.

[0075] In some embodiments of the present invention, see Figures 3a to 4 , Figure 3a for Figure 2b A magnified schematic diagram of part A; Figure 3b for Figure 2b An enlarged schematic diagram of part A from another angle; Figure 4 for Figure 2bSchematic diagram of the exploded view of the ground walking mechanism shown.

[0076] like Figures 3a to 4 As shown, the drive assembly 231 includes a motor assembly and a travel wheel 2313. The motor assembly has a first output shaft 2314 perpendicular to the length of the roadway. The travel wheel 2313 is mounted on the first output shaft 2314 and moves on the ground under the drive of the first output shaft 2314. The travel wheel 2313 is connected to the mounting assembly 232 via the first output shaft 2314.

[0077] The motor assembly includes a driving motor 2311 and a reducer 2312. The driving motor 2311 is drivingly connected to the reducer 2312; a first output shaft 2314 extends from the reducer 2312 to drive the walking wheel 2313 to move on the ground.

[0078] Specifically, the number of the running wheels 2313 and the first output shaft 2314 can be one or more, and each first output shaft 2314 is sleeved with at least one running wheel 2313 .

[0079] like Figure 4 As shown in the specific embodiment of the present invention, two first output shafts 2314 extend from the reducer 2312 and are respectively arranged on a pair of opposite surfaces of the reducer 2312 in a direction perpendicular to the roadway. A travel wheel 2313 is sleeved on each first output shaft 2314.

[0080] The driving motor 2311 drives the running wheels 2313 to roll on the ground, and drives the support frame 210 to slide along the horizontal direction of the shelf 100 based on the multiple horizontal tracks 300 through the mounting assembly 232.

[0081] According to the embodiment of the present invention, the transport robot 200 drives the walking wheels 2313 to roll on the ground through the driving motor 2311 of the motor assembly, so as to slide horizontally along the shelf 100 .

[0082] In some embodiments of the present invention, Figures 3a to 4 As shown, the mounting assembly 232 includes: a mounting frame 2321 and a bearing seat 2322 .

[0083] The support frame 210 is a column gantry; the mounting frame 2321 is arranged between the two columns 210a of the support frame 210, and is fixedly connected to the bottom of the support frame 210 or movably connected along the vertical direction; the bearing seat 2322 is fixedly arranged in the mounting frame 2321 and connected to the motor assembly.

[0084] The motor assembly further includes a second output shaft 2315 parallel to the length direction of the lane; the second output shaft 2315 is rotatably engaged with the bearing seat 2322 .

[0085] Specifically, the second output shaft 2315 and the drive motor 2311 are arranged on another set of opposite surfaces of the reducer 2312; one or more coaxially arranged bearings 2323 are provided on the bearing seat 2322, and the inner ring of the bearing 2323 is interference fit with the second output shaft 2315.

[0086] In a specific embodiment of the present invention, Figures 3a to 4 As shown, the mounting frame 2321 can be a rectangular hollow frame, and the bearing seat 2322 is disposed inside the mounting frame 2321, with both ends fixedly connected to the front and rear side walls of the mounting frame 2321. It should be noted that the front and rear side walls of the mounting frame 2321 are the side walls parallel to the shelf 100. The drive assembly 231 is disposed inside the mounting frame 2321, and the second output shaft 2315 is capable of rotating on the bearing seat 2322.

[0087] In the embodiment of the present invention, the mounting frame 2321 is disposed between the two uprights 210a of the support frame 210 and is fixedly connected to the bottom of the support frame 210 or movably connected in the vertical direction, thereby improving the stability of the support frame 210. Driven by the drive motor 2311, the running wheels 2313 roll horizontally along the shelf 100, and the support frame 210 is driven to slide along the horizontal track 300 via the bearing seat 2322 and the mounting frame 2321.

[0088] In some embodiments of the present invention, Figures 3a to 4 As shown, the ground traveling mechanism 230 is further provided with a first suspension structure 240. The first suspension structure 240 is connected to the support frame 210 and the mounting assembly 232, and is used to drive the ground traveling mechanism 230 to float along with the ups and downs of the ground.

[0089] Specifically, a group of first suspension structures 240 are respectively provided at both ends of the ground walking mechanism 230; the installation component 232 is movably connected to the bottom of the support frame 210 along the vertical direction through the first suspension structure 240, and drives the ground walking mechanism 230 to float with the ups and downs of the ground, so that the ground walking mechanism 230 is always in contact with the ground.

[0090] By applying the embodiment of the utility model, when the transport robot 200 moves, the first suspension structure 240 provides a pressing force toward the ground to the ground walking mechanism 230, and the ground walking mechanism 230 can float relative to the support frame 210 as the ground rises and falls, thereby preventing the walking wheels 2313 of the ground walking mechanism 230 from leaving the ground due to uneven ground. The walking wheels 2313 are always in contact with the ground, which also ensures sufficient friction between the ground and the walking wheels 2313, making the movement of the transport robot 200 more stable.

[0091] In some embodiments of the present invention, Figures 3a to 4As shown, the first suspension structure 240 includes: a first elastic member 241; one end of the first elastic member 241 is fixedly connected to the support frame 210, and the other end is fixedly connected to the mounting assembly 232; the first elastic member 241 can apply an elastic force to the ground walking mechanism 230 to press toward the ground.

[0092] The first suspension structure 240 further includes a first sliding member 242. The first elastic member 241 and the first sliding member 242 are respectively disposed on both sides of the support frame 210, and are used to cooperate with each other to drive the ground walking mechanism 230 to float along with the ups and downs of the ground.

[0093] Specifically, the first elastic member 241 and the first sliding member 242 are both arranged in the vertical direction, wherein the top end of the first elastic member 241 is fixedly connected to the support frame 210 , and the bottom end is fixedly connected to the mounting assembly 232 .

[0094] By applying the embodiment of the utility model, the first elastic member 241 and the first sliding member 242 cooperate with each other so that the ground walking mechanism 230 can not only support the transport robot 200 but also float relative to the support frame 210 as the transport robot 200 moves with the ups and downs of the ground, thereby avoiding the walking wheels 2313 of the ground walking mechanism 230 leaving the ground due to uneven ground. The walking wheels 2313 are always in contact with the ground, which also ensures sufficient friction between the ground and the walking wheels 2313, making the movement of the transport robot 200 more stable.

[0095] In some embodiments of the present invention, Figures 3a to 4 As shown, the first sliding member 242 includes: a first slider 242a and a first slide rail 242b; the first slider 242a is fixedly connected to the support frame 210; one side of the first slide rail 242b is fixedly connected to the mounting assembly 232, and the other side is slidably connected to the first slider 242a.

[0096] In a specific embodiment of the present invention, Figures 3a to 4 As shown, the first elastic members 241 and the first sliding members 242 of the two sets of first suspension structures 240 are respectively arranged at a corner of the mounting frame 2321 , and the column 210 a of the support frame 210 is sandwiched between the set of first elastic members 241 and the first sliding members 242 .

[0097] The first elastic member 241 can be a spring, and the top and bottom ends are fixedly connected to the column 210a and the mounting frame 2321 respectively; so that when the transport robot 200 moves, the first slide rail 242b on the mounting frame 2321 can slide up and down relative to the first slider 242a on the column 210a.

[0098] By applying the embodiment of the utility model, the first slider 242a and the first slide rail 242b cooperate with each other to guide the up and down floating of the ground walking mechanism 230, so that it floats in the vertical direction, ensuring that the horizontal movement of the ground walking mechanism 230 and the support frame 210 in the tunnel direction is synchronized.

[0099] In some embodiments of the present invention, Figures 2a to 2c As shown, the transport robot 200 further includes at least one lateral shift drive mechanism 260. The at least one lateral shift drive mechanism 260 is disposed on the support frame 210 and is respectively connected to the horizontal track 300 in a rolling manner. The at least one lateral shift drive mechanism 260 is used to cooperate with the ground walking mechanism 230 to move the transport robot 200 in the horizontal direction along the first shelf 100A.

[0100] The transport robot further includes a plurality of auxiliary wheel sets 250 , which are disposed on the support frame 210 .

[0101] Multiple auxiliary wheel groups 250 and at least one lateral drive mechanism 260 are each rollingly connected to the horizontal track 300 located at the same height; so that the transport robot 200 is hung on the first shelf 100A through multiple auxiliary wheel groups 250 and at least one lateral drive mechanism 260.

[0102] Specifically, the present invention does not limit the arrangement order of the multiple auxiliary wheel groups 250 and at least one lateral shift drive mechanism 260 on the support frame 210. In a specific embodiment of the present invention, two upper and lower horizontal rails 300 are fixed to the outside of the shelf 100, and the support frame 210 is provided with a lateral shift drive mechanism 260 and an auxiliary wheel group 250 arranged in an upper and lower interval, which are respectively connected in a rolling manner to the upper horizontal rail 300 and the lower horizontal rail 300. The multiple auxiliary wheel groups 250 are relatively arranged on the two columns 210a of the support frame 210, and the two auxiliary wheel groups 250 at the same height are connected in a rolling manner to the same horizontal rail 300, which can improve the stability of the transport robot 200 sliding on the horizontal rail 300.

[0103] In this embodiment of the present invention, the transport robot 200 is mounted on the exterior of the shelf 100 using auxiliary wheels 250 and a lateral drive mechanism 260. Part of the driving force for the transport robot 200's horizontal movement comes from the movement of the drive assembly 231 relative to the ground; the remaining driving force comes from the lateral drive mechanism 260 driving the support frame 210 to slide along the horizontal track 300. The auxiliary wheels 250 improve the efficiency and stability of the support frame 210's movement on the horizontal track 300.

[0104] In some embodiments of the present invention, see Figures 5 to 6b , Figure 5 for Figure 2b An enlarged schematic diagram of part B; Figure 6a for Figure 5 A three-dimensional structural diagram of the side shift drive mechanism shown; Figure 6b for Figure 6a A three-dimensional structural diagram of the side shift drive mechanism from another angle.

[0105] like Figures 5 to 6b As shown, each lateral shift driving mechanism 260 includes a lateral shift motor 261 and two driving wheel sets 262 .

[0106] The two driving wheel groups 262 are relatively fixed on the support frame 210 and are rollingly connected to the same horizontal track 300; the side shift motor 261 is drivingly connected to the driving wheel group 262, and drives the support frame 210 to move on the horizontal track 300 through the driving wheel group 262.

[0107] Specifically, the two driving wheel groups 262 are relatively fixed on the two columns 210a of the support frame 210 and are rollingly connected to the same horizontal track 300; the side shift motor 261 is drivingly connected to the driving wheel group 262, and drives the support frame 210 to move horizontally on the horizontal track 300 through the driving wheel group 262.

[0108] In this embodiment of the present invention, two opposing drive wheel assemblies 262 are provided in rolling connection with the horizontal track 300, thereby improving the stability of the transport robot 200 as it slides horizontally on the horizontal track 300. The side shift motor 261 drives the drive wheel assemblies 262, which in turn drives the support frame 210 to slide horizontally on the horizontal track 300, enabling the bin pick-and-place assembly 220 to pick up and place different bins along the length of the shelf 100.

[0109] In some embodiments of the present invention, Figures 5 to 6b As shown, the driving wheel set 262 includes a first driving wheel 263 , a second driving wheel 264 and a third driving wheel 265 .

[0110] The first driving wheel 263 is located above the horizontal track 300 and is rollingly connected to the top surface of the horizontal track 300; the second driving wheel 264 and the third driving wheel 265 are located below the horizontal track 300; they are used to cooperate with each other so that the support frame 210 can move based on the horizontal track 300.

[0111] In this embodiment of the present invention, first, second, and third drive wheels 263, 264, and 265 are provided, which are in rolling connection with the horizontal rail 300. This converts the sliding friction between the support frame 210 and the horizontal rail 300 into rolling friction, enabling the support frame 210 to move rapidly along the horizontal rail 300. The first drive wheel 263 is located above the horizontal rail 300, while the second and third drive wheels 264, 265 are located below the horizontal rail 300. The transport robot 200 clamps the horizontal rail 300 from both the upper and lower directions via the drive wheel assembly 262, allowing it to be mounted on the first shelf 100A located on one side of the laneway. This improves the stability of the transport robot 200 during installation and horizontal movement.

[0112] In some embodiments of the present invention, Figures 5 to 6b As shown, the drive wheel assembly 262 further includes a third suspension structure 266 .

[0113] The third suspension structure 266 is fixedly connected to the support frame 210, and the second drive wheel 264 and the third drive wheel 265 are fixed on the third suspension structure 266, wherein the second drive wheel 264 is rollingly connected to the bottom of the horizontal track 300 and is drive-connected to the side shift motor 261; the third drive wheel 265 is rollingly connected to the inner wall of the horizontal track 300.

[0114] The third suspension structure 266 can float in a horizontal direction relative to the support frame 210 to apply a horizontal positive pressure to the support frame 210 .

[0115] Specifically, a downward-facing groove 310 is provided at the bottom of the horizontal track 300, which is in rolling connection with the two drive wheel sets 262. The first drive wheel 263 and the second drive wheel 264 are arranged vertically, and the third drive wheel 265 is arranged horizontally. The second drive wheel 264 is in rolling connection with the top surface of the groove 310 at the bottom of the horizontal track 300 and is in driving connection with the side shift motor 261. The third drive wheel 265 is in rolling connection with the sidewall of the groove 310 at the bottom of the horizontal track 300.

[0116] The third suspension structure 266 applies horizontal positive pressure to the support frame 210. During the movement of the transport robot 200, when the part of the support frame 210 where the lateral drive mechanism 260 is located moves faster than the other part, the direction of the positive pressure is opposite to the movement direction; when it is slower than the other part, the direction of the positive pressure is the same as the movement direction, so that the upper and lower parts of the support frame 210 move synchronously and constrain the swing angle.

[0117] In this embodiment of the present invention, the first and second drive wheels 263 and 264 are arranged vertically, while the third drive wheel 265 is arranged horizontally. This increases the contact area between the drive wheel assembly 262 and the bottom groove 310 of the horizontal track 300, thereby improving the efficiency and stability of the support frame 210 when moving on the horizontal track 300. A third suspension structure 266 is provided to apply pressure to the support frame 210 to constrain the swing angle of the support frame 210 when moving along the horizontal track 300, ensuring that the support frame 210 moves synchronously on each horizontal track 300.

[0118] In some embodiments of the present invention, Figures 5 to 6b As shown, the third suspension structure 266 includes a third elastic member 2661. The third elastic member 2661 is arranged in the horizontal direction, with one end fixedly connected to the support frame 210 and the third driving wheel 265, and the other end fixedly connected to the second driving wheel 264; the third elastic member 2661 can apply horizontal positive pressure to the support frame 210.

[0119] Specifically, the third elastic member 2661 can be a spring, which makes the structure of the third suspension structure 266 simpler and lighter, so as to reduce the weight of the transport robot 200, reduce the load borne by the shelf 100, and increase the service life of the horizontal rail 300 and the shelf 100.

[0120] One end of the third elastic member 2661 is fixedly connected to the column 210a of the support frame 210 through the first fixing member 2662. The first fixing member 2662 extends toward the groove 310 at the bottom of the horizontal track 300, and the third driving wheel 265 is fixed to the end so that the third driving wheel 265 is located in the groove 310 at the bottom and is rollingly connected to the side wall of the groove 310 at the bottom; the other end is fixedly connected to the second driving wheel mounting seat 2664 through the second fixing member 2663.

[0121] By applying the embodiment of the present utility model, the third suspension structure 266 applies horizontal positive pressure to the support frame 210 through the third elastic member 2661, which can constrain the swing angle of the support frame 210 when moving along the horizontal track 300, thereby ensuring that the support frame 210 moves synchronously on each horizontal track 300.

[0122] In some embodiments of the present invention, see Figures 7 to 8b , Figure 7 for Figure 2b A magnified schematic diagram of part C; Figure 8a for Figure 7 A three-dimensional structural diagram of the auxiliary wheel assembly shown; Figure 8b for Figure 8a A three-dimensional structural diagram of the auxiliary wheel assembly from another angle.

[0123] like Figures 7 to 8bAs shown, each auxiliary wheel set 250 includes an auxiliary wheel 251 ; the auxiliary wheel 251 is rollingly connected to the horizontal track 300 .

[0124] Each auxiliary wheel set 250 further includes a second suspension structure 252 . The second suspension structure 252 is located above the horizontal track 300 and is fixedly connected to the support frame 210 . The auxiliary wheels 251 are disposed on the second suspension structure 252 and are located above the horizontal track 300 .

[0125] The second suspension structure 252 can float in the vertical direction relative to the horizontal track 300 so that the auxiliary wheels 251 are always pressed against the horizontal track 300 .

[0126] Specifically, the top of the horizontal track 300, which is rollably connected to the auxiliary wheel assembly 250, is provided with an upwardly opening groove 310. The auxiliary wheels 251 are mounted on the second suspension structure 252, located within the groove 310 at the top of the horizontal track 300, and are capable of rolling within the groove 310. The support frame 210 is positioned above the horizontal track 300 via the auxiliary wheels 251 and is mounted within the groove 310 at the top of the horizontal track 300. It is then suspended from the first shelf 100A located on one side of the aisle.

[0127] The second suspension structure 252 can float in the vertical direction relative to the horizontal track 300 so that the auxiliary wheel 251 is always located in the groove 310 at the top of the horizontal track 300 .

[0128] During the movement of the transport robot 200, the support frame 210 will float in the vertical direction as the ground rises and falls. When the auxiliary wheel 251 on the support frame 210 wants to float upward relative to the horizontal track 300, the second suspension structure 252 applies pressure to the auxiliary wheel 251 so that the auxiliary wheel 251 is always located in the groove 310 at the top of the horizontal track 300.

[0129] In addition, since there may be errors in the installation position of the horizontal rail 300 on the first shelf 100A, the spacing value between the upper and lower horizontal rails 300 deviates from the predetermined spacing. At this time, when the transport robot 200 is installed on the horizontal rail 300, the second suspension structure 252 can adjust the position of the auxiliary wheel 251 in the vertical direction relative to the support frame 210 based on itself to ensure that the auxiliary wheel 251 is always located in the groove 310 at the top of the horizontal rail 300.

[0130] By applying the embodiment of the present invention, the auxiliary wheel 251 is always pressed against the horizontal track 300 by the second suspension structure 252 to prevent it from falling off the horizontal track 300 , thereby improving the stability of the transport robot 200 sliding on the horizontal track 300 .

[0131] In some embodiments of the present invention, Figures 7 to 8bAs shown, the second suspension structure 252 includes a second elastic member 2521. One end of the second elastic member 2521 is fixedly connected to the support frame 210, and the other end is fixedly connected to the auxiliary wheel 251; the second elastic member 2521 can apply an elastic force to the auxiliary wheel 251 to press it toward the horizontal track 300.

[0132] The second suspension structure 252 also includes a second sliding member 2522. The second sliding member 2522 includes a second slider 2522a and a second slide rail 2522b. The second slider 2522a is fixedly connected to the auxiliary wheel 251; the second slide rail 2522b is fixedly connected to the support frame 210 on one side and slidably connected to the second slider 2522a on the other side.

[0133] Specifically, the second elastic member 2521 and the second sliding member 2522 are both arranged in the vertical direction, wherein the top end of the second elastic member 2521 is fixedly connected to the support frame 210 , and the bottom end is fixedly connected to the auxiliary wheel 251 .

[0134] The auxiliary wheel 251 is based on the second elastic member 2521 and the second sliding member 2522 and is always located in the groove 310 at the top of the horizontal track 300 .

[0135] The second elastic member 2521 can be a spring, which makes the structure of the second suspension structure 252 simpler and lighter, thereby reducing the weight of the transport robot 200, reducing the load borne by the first shelf 100A, and increasing the service life of the horizontal rail 300 and the first shelf 100A.

[0136] The top end of the second elastic member 2521 is fixedly connected to the column 210a of the support frame 210 through the third fixing member 2523, and the bottom end is fixedly connected to the auxiliary wheel 251 through the fourth fixing member 2524. When the transport robot 200 moves, it can apply an elastic force to the auxiliary wheel 251 to press toward the horizontal track 300, so that the second slide rail 2522b can slide up and down relative to the second slider 2522a on the column 210a of the support frame 210.

[0137] By applying the embodiment of the present invention, the second elastic member 2521 and the second sliding member 2522 ensure that the auxiliary wheel 251 is always located in the top groove 310 of the horizontal track 300, preventing it from falling off the horizontal track 300, thereby improving the stability of the transport robot 200 sliding on the horizontal track 300.

[0138] In some embodiments of the present invention, Figures 7 to 8b As shown, the auxiliary wheel 251 includes a first auxiliary wheel 2511 , a second auxiliary wheel 2512 and an auxiliary wheel mounting seat 2513 .

[0139] The auxiliary wheel mounting seat 2513 is fixedly connected to the second suspension structure 252 ; the first auxiliary wheel 2511 and the second auxiliary wheel 2512 are fixed side by side on the auxiliary wheel mounting seat 2513 .

[0140] The first auxiliary wheel 2511 is rollingly connected to the inner wall of the horizontal track 300 ; the second auxiliary wheel 2512 is rollingly connected to the top of the horizontal track 300 .

[0141] Specifically, the first auxiliary wheel 2511 is arranged horizontally and rollingly connected to the side wall of the groove 310 at the top of the horizontal track 300 ; the second auxiliary wheel 2512 is arranged vertically and rollingly connected to the bottom of the groove 310 at the top of the horizontal track 300 .

[0142] Specifically, the auxiliary wheel mounting base 2513 is fixedly connected to the fourth fixing member 2524 of the second suspension structure 252. In the embodiment of the present invention, the first auxiliary wheel 2511 is arranged horizontally, and the second auxiliary wheel 2512 is arranged vertically. This increases the contact area between the auxiliary wheels 251 and the top groove 310 of the horizontal track 300, thereby improving the efficiency and stability of the support frame 210 moving on the horizontal track 300.

[0143] In some embodiments of the present invention, Figures 1a to 2b As shown, the transport robot further includes a lifting mechanism 270 . The lifting mechanism 270 is disposed on the support frame 210 and can drive the material box pick-up and place assembly 220 to rise and fall along the support frame 210 to pick up and place material boxes at different heights on the shelf 100 .

[0144] Specifically, in a specific embodiment of the present invention, the handling robot 200 also includes two sets of lifting mechanisms 270, and the material box picking and placing assembly 220 is arranged between the two columns 210a of the support frame 210, and is slidably connected to the support frame 210 along the vertical direction; the two sets of lifting mechanisms 270 are respectively arranged on the two columns 210a of the support frame 210, and can drive the material box picking and placing assembly 220 to rise and fall along the support frame 210 to pick up and place material boxes at different heights on the shelf 100.

[0145] Each lifting mechanism 270 may include a lifting motor 271, a conveyor belt 272, and two transmission wheels 273. The two transmission wheels 273 are respectively fixed to the top and bottom of the column 210a of the support frame 210. The lifting motor 271 is drivingly connected to the bottom transmission wheel 273 and is fixed to the column 210a of the support frame 210. The conveyor belt 272 passes around the bottom transmission wheel 273 and the top transmission wheel 273 and is fixedly connected to the bin pick-and-place assembly 220 at both ends. The lifting motor 271 drives the transmission wheels and the conveyor belt 272, which can drive the bin pick-and-place assembly 220 to slide vertically along the support frame 210 to pick and place bins at different heights on the shelf 100.

[0146] When applying the embodiment of the present utility model, the material box picking and placing component 220 is driven by the lifting mechanism 270, and can be raised and lowered along the support frame 210 to pick up and place material boxes at different heights on the shelf 100; it can also follow the support frame 210 to move in the horizontal direction of the shelf 100 to pick up and place different material boxes in the length direction of the shelf 100.

[0147] In some embodiments of the present invention, Figures 1a to 2a As shown, the transport robot 200 also includes a control device 280 for controlling the movement of the transport robot 200 and the placement and retrieval of bins. The control device 280 is positioned alongside the support frame 210 outside the shelf 100 and is fixedly connected to the mounting frame 2321 of the ground travel mechanism 230. The control device 280 has rollers at its bottom for contact with the ground, enabling it to move horizontally along the shelf 100 with the support frame 210.

[0148] like Figure 2a As shown, a drag chain 211 is further provided on the support frame 210 for restraining the cables of the transport robot 200 .

[0149] The storage device provided by the embodiment of the present utility model is described below.

[0150] The storage device provided by the embodiment of the present utility model is as follows: Figure 1a and Figure 1b As shown, it includes the shelves 100 described in any of the above embodiments and at least one transport robot 200, and aisles are formed between adjacent shelves 100.

[0151] The transport robot 200 is mounted on a first shelf 100A located at one side of the lane, and the ground walking mechanism 230 at the bottom of the transport robot 200 is located at one side of the lane close to the first shelf 100A.

[0152] Specifically, when there are two transport robots 200, they can be mounted on either side of the first shelf 100A in the longitudinal direction to simultaneously pick up and place bins from both sides of the shelf 100. If the shelf 100 is long enough, two or more transport robots 200 can also be positioned on the same side of the first shelf 100A. The present invention does not limit the installation arrangement of the transport robots 200 on the first shelf 100A.

[0153] In the storage device provided by the present invention, a handling robot 200 is mounted on a first shelf 100A located on one side of an aisle via a support frame 210 and is capable of sliding horizontally along shelf 100. A ground running mechanism 230 is located on the side of the aisle near first shelf 100A and is configured to engage the ground surface on which shelf 100 rests, providing support and driving force for the handling robot 200. A portion of the weight of the handling robot 200 is applied to the ground via the ground running mechanism 230, reducing the load on shelf 100 and, in turn, lowering the load-bearing capacity requirements of shelf 100.
