[0062] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0063] like Figure 1 and Figure 2 As shown in the embodiment of this application, a transport vehicle is provided for transporting materials. During transport, the materials are first placed in a transfer tray, and then the transfer tray is placed in the transport vehicle. The transport vehicle then transports the materials to the processing equipment.

[0064] The transport vehicle includes a support frame 1, rollers 2, and a storage layer 3, both of which are mounted on the support frame 1. The storage layer 3 includes a first type of storage layer 31 and a second type of storage layer 32, with the second type of storage layer 32 located on the side of the first type of storage layer 31 closest to the rollers 2. The support frame 1 includes a guide rail 11, with the rollers 2 mounted on the bottom of the support frame 1. The second type of storage layer 32 is movably mounted on the guide rail 11, which extends along a first direction, which can be either the width or length direction of the transport vehicle, allowing the second type of storage layer 32 to move along the first direction.

[0065] The support frame 1, with the rollers 2 on one side, is placed on the ground so that the rollers 2 support the support frame 1 to facilitate pushing the transport vehicle. In one possible embodiment, the rollers 2 can be omnidirectional wheels, allowing the transport vehicle to move in multiple directions. The surface of the rollers 2 can be made of polyurethane material, which can improve the shock absorption and noise reduction effect of the rollers 2.

[0066] The support frame 1 is equipped with a first type of storage layer 31 and a second type of storage layer 32. Materials can be placed on both the first type of storage layer 31 and the second type of storage layer 32, which improves the carrying capacity of the transport vehicle and thus improves the efficiency of material transfer. The support frame 1 includes multiple support columns 13, which are spaced apart and can enclose an accommodating space 14. The guide rail 11, the first type of storage layer 31 and the second type of storage layer 32 are all located within the accommodating space 14. The first type of storage layer 31 is fixedly installed on the support frame 1. The height of the first type of storage layer 31 is moderate, making it convenient for workers to place materials from the side of the support frame 1 onto the first type of storage layer 31.

[0067] The second type of shelf 32 is located on the side of the first type of shelf 31 that is closer to and / or farther away from the roller 2, such as Figure 1 As shown, when the second type of storage layer 32 is located on the side of the first type of storage layer 31 near the roller 2, the position of the second type of storage layer 32 is low, making it inconvenient to take or place materials on the second type of storage layer 32. By installing the second type of storage layer 32 on the guide rail 11, the operator can pull the second type of storage layer 32 so that the second type of storage layer 32 can protrude from the receiving space 14 along the first direction, so as to facilitate the taking or placing of materials on the second type of storage layer 32.

[0068] When the second type of shelf 32 is located on the side of the first type of shelf 31 away from the roller 2 (not shown in the figure), the position of the second type of shelf 32 is too high, making it inconvenient to pick up or put down materials on the second type of shelf 32. By installing the second type of shelf 32 on the guide rail 11, the operator can pull the second type of shelf 32 so that the second type of shelf 32 can protrude out of the receiving space 14 along the first direction, so as to facilitate the picking up or putting down of materials on the second type of shelf 32.

[0069] like Figure 1 and Figure 2 As shown, in one possible embodiment, a crash bar 15 is provided on the side of the support column 13 away from the receiving space 14, and the crash bar 15 protrudes from the support column 13. During the movement of the transport vehicle, the support column 13 in the transport vehicle may collide with other devices. The crash bar 15 can reduce the possibility of damage to the support column 13 during the collision, which is beneficial to improving the reliability and service life of the transport vehicle.

[0070] like Figure 3 As shown, in one possible embodiment, the first type of storage layer 31 includes at least one first storage layer 311, all of which are fixedly installed on the bracket 1 and located within the accommodating space 14. When the first type of storage layer 31 includes two or more first storage layers 311, the two or more first storage layers 311 are spaced apart along the height direction of the transport vehicle. The second type of storage layer 32 includes at least one second storage layer 323. When the second type of storage layer 32 includes two or more second storage layers 323, the at least one second storage layer 323 is spaced apart along the height direction of the transport vehicle to improve the carrying capacity of the transport vehicle.

[0071] When the second type of storage layer 32 includes two or more second storage layers 323, each second storage layer 323 is provided with a set of guide rails 11, so that each second storage layer 323 can be installed on the guide rails 11. When materials are picked up or put down, the second storage layer 323 can be pulled out of the receiving space 14 along the first direction. When the bracket 1 includes two or more sets of guide rails 11, the two or more sets of guide rails 11 are spaced apart along the height direction of the transport vehicle.

[0072] like Figure 4 and Figure 5 As shown, in one possible embodiment, each second type of shelf 32 is provided with at least two spaced guide rails 11, which are spaced apart along a second direction perpendicular to the first direction. The second type of shelf 32 is mounted on the guide rails 11, and the at least two spaced guide rails 11 can improve the stability of the second type of shelf 32 after installation and also improve the load-bearing capacity of the second type of shelf 32.

[0073] refer to Figure 5 and Figure 6In one possible embodiment, the second type of shelf 32 includes a first slider 321 and a second slider 322, which are located on the side of the second type of shelf 32 near the roller 2. The second type of shelf 32 is movably connected to the guide rail 11 through the first slider 321 and the second slider 322. The first slider 321 and the second slider 322 are located in the middle of the second type of shelf 32, so that the second type of shelf 32 can be pulled out from both sides of the bracket 1 in a first direction to facilitate the loading and unloading of materials.

[0074] like Figure 2 As shown, in one possible embodiment, anti-collision blocks 111 are provided at both ends of the guide rail 11. Along the first direction, the first slider 321 and the second slider 322 are spaced apart. After the second type of storage layer 32 is pulled out along the direction of the second slider 322 pointing to the first slider 321, it accommodates the space 14. The first slider 321 abuts against the anti-collision block 111 at one end of the guide rail 11. After the second type of storage layer 32 is pulled out along the direction of the first slider 321 pointing to the second slider 322, it accommodates the space 14. The second slider 322 abuts against the anti-collision block 111 at the other end of the guide rail 11.

[0075] Along the first direction, the width of the second type of shelf 32 is d, and the distance between the first slider 321 and one end of the second type of shelf 32 is d1, where d1 ≤ 1 / 3d, such that the dimension by which the second type of shelf 32 is pulled out along the direction from the second slider 322 to the first slider 321 is less than or equal to 1 / 3 of the width of the second type of shelf 32. The distance between the second slider 322 and the other end of the second type of shelf 32 is d2, where d2 ≤ 1 / 3d, such that the dimension by which the second type of shelf 32 is pulled out along the direction from the first slider 321 to the second slider 322 is less than or equal to 1 / 3 of the width of the second type of shelf 32.

[0076] The second type of storage layer 32 is used to hold materials. When the second type of storage layer 32 is pulled out of the receiving space 14, it will cause the center of gravity of the transport vehicle to shift. The positions of the first slider 321 and the second slider 322 can limit the size by which the second type of storage layer 32 is pulled out, thereby controlling the degree of shift in the center of gravity of the transport vehicle. The distance between the first slider 321 and the second slider 322 and the edge of the second type of storage layer 32 is less than or equal to 1 / 3 of the width of the second type of storage layer 32, which can reduce the center shift of the transport vehicle, reduce the possibility of the transport vehicle overturning, and improve the stability of the transport vehicle when picking up and placing materials, thus improving the safety of the material handling process.

[0077] like Figure 5 and Figure 6As shown, in one possible embodiment, the transport vehicle includes a check valve assembly 4, which is mounted on the side of the second type of storage layer 32 near the roller 2. When the second type of storage layer 32 is located within the receiving space 14, the check valve assembly 4 abuts against the bracket 1.

[0078] The second type of storage layer 32 is movably mounted on the slide rail. The anti-return component 4 abuts against the bracket 1, which can limit the relative position of the second type of storage layer 32 and the bracket 1. During the movement of the transport vehicle, it can reduce the possibility of the second type of storage layer 32 protruding out of the accommodating space 14, thereby reducing the possibility of materials falling off the second type of storage layer 32, which is conducive to improving the reliability of the transport vehicle during the transfer process.

[0079] Along the first direction, both ends of the second type of shelf 32 are provided with check valve components 4. Taking the example of installing a first check valve component 44 and a second check valve component 45 at both ends of the second type of shelf 32 respectively, when the second type of shelf 32 is located in the receiving space 14, the first check valve component 44 and the second check valve component 45 abut against the two crossbeams opposite to the bracket 1 to restrict the position of the second type of shelf 32 within the receiving space 14. When the side of the second type of shelf 32 where the first check valve component 44 is installed is pulled out of the receiving space 14, the first check valve component 44 releases from the bracket 1 and moves away from the receiving space 14 along with the second type of shelf 32. The second check valve component 45 releases from the bracket 1 and moves away from the crossbeam it abuts within the receiving space 14. When the second type of shelf 32 is pushed back into the receiving space 14, the first anti-return component 44 moves with the second type of shelf 32 toward the receiving space 14. After the second type of shelf 32 moves into the receiving space 14, the second anti-return component 45 abuts against the bracket 1, causing the second type of shelf 32 to stop moving. This reduces the possibility that the second type of shelf 32 may protrude from the side where the second anti-return component 45 is installed into the receiving space 14.

[0080] like Figure 7 , Figure 8 and Figure 9 As shown, in one possible embodiment, the check valve assembly 4 includes a first mounting member 41, a check valve block 42, and a handle 43. The first mounting member 41 is mounted on the second type of shelf 32, and both the check valve block 42 and the handle 43 are mounted on the first mounting member 41. One end of the check valve block 42 is rotatably connected to the first mounting member 41, and the other end is connected to the handle 43. The handle 43 allows the check valve block 42 to rotate relative to the first mounting member 41. The side of the check valve block 42 connected to the handle 43 abuts against the bracket 1.

[0081] The end of the check block 42 connected to the handle 43 includes a mounting portion 421 and an abutment portion 422. The connecting portion 61 is located on the side of the abutment portion 422 near the second type of shelf 32. When the second type of shelf 32 is in the receiving space 14, the abutment portion 422 is located within the receiving space 14 and abuts against the bracket 1. The handle 43 is located between the second type of shelf 32 and the bracket 1 and protrudes from the receiving space 14. When the second type of shelf 32 is pulled out, the operator drives the handle 43 to move towards the second type of shelf 32 (e.g., ...). Figure 7 (As indicated by the middle arrow), this causes the check block 42 to rotate relative to the first mounting member 41, disengaging the abutment portion 422 from the bracket 1, thus facilitating the pulling out of the second type of shelf 32. When the second type of shelf 32 is pushed back, the check block 42 moves back to the receiving space 14 along with the second type of shelf 32, and then the check block 42 resets, causing the abutment portion 422 in the check block 42 to abut against the bracket 1.

[0082] like Figure 7 , Figure 8 and Figure 9 As shown, in one possible embodiment, the first mounting member 41 includes a mounting groove 411, and a check block 42 is mounted within the mounting groove 411. The first mounting member 41 also includes a rotating shaft 412, which is mounted in the mounting groove 411. The check block 42 includes a connecting hole, allowing the check block 42 to be rotatably mounted on the rotating shaft 412. The first mounting member 41 includes a limiting member 413 and an elastic member 414, both located between the check block 42 and the inner wall of the mounting groove 411. The limiting member 413 and the elastic member 414 are located on opposite sides of the rotating shaft 412, with the limiting member 413 located on the side of the rotating shaft 412 away from the handle 43, and the elastic member 414 located on the side of the rotating shaft 412 closer to the handle 43.

[0083] When the second type of storage layer 32 is located in the accommodating space 14, both the limiting member 413 and the elastic member 414 abut against the check block 42, which reduces the possibility of the check block 42 rotating relative to the rotating shaft 412 during the transfer process. If the transport vehicle experiences unstable conditions such as bumps during the transfer process, the elastic member 414 reduces the possibility of the abutting part 422 of the check block 42 disengaging from the bracket 1, which helps to improve the stability during the transfer process.

[0084] Before the second type of shelf 32 is pulled out, the operator drives the handle 43 to move closer to the second type of shelf 32, causing the check block 42 to rotate around the rotation axis 412. The limiting member 413 contacts and abuts against the check block 42, and the elastic member 414 is compressed, causing the abutting part 422 of the check block 42 to disengage from the bracket 1, allowing the second type of shelf 32 to be pulled out of the receiving space 14. When the force on the handle 43 is released, the check block 42 returns to its original position under the elastic force of the elastic member 414. At this time, the limiting member 413 abuts against the check block 42 to limit the rotation angle of the check block 42 when it returns to its original position.

[0085] After the check valve assembly 4 disengages from the receiving space 14, the check valve block 42 resets under the action of the elastic member 414. A guide surface 423 is provided on the side of the check valve block 42 away from the limiting member 413 and the elastic member 414. Along the direction of the handle 43 pointing towards the rotation axis 412, the guide surface 423 is inclined towards the second type of shelf 32. When the second type of shelf 32 is pushed back into the receiving space 14, the bracket 1 abuts against the guide surface 423 and slides along the guide surface 423, which can compress the elastic member 414 again, allowing the check valve block 42 to move into the receiving space 14. After the check valve block 42 moves into the receiving space 14, the elastic member 414 returns to its original position, causing the abutting part 422 of the check valve block 42 to abut against the bracket 1.

[0086] like Figure 6 and Figure 10 As shown, in one possible embodiment, the shelf layer 3 includes a frame 36 located at the edge of the shelf layer 3 and forming the shape of the shelf layer 3. The frame 36 in the first type of shelf layer 31 is fixedly connected to the bracket 1 to fix the first type of shelf layer 31 to the bracket 1. The first slider 321 and the second slider 322 in the second type of shelf layer 32 are mounted to the frame 36 by a fastener 37, and then connected to the guide rail 11.

[0087] like Figure 6 and Figure 10 As shown, in one possible embodiment, the shelf layer 3 includes a shelf 33 and a plurality of support members 34. The plurality of support members 34 are spaced apart and connected to the frame 36, so that the support members 34 are mounted on the bracket 1. The shelf 33 is located on the side of the support members 34 and the frame 36 away from the roller 2, and is fixedly connected to the frame 36 and the support members 34.

[0088] The shelf 33 is a rigid plate structure such as a metal plate. The material is placed on the side of the shelf 33 away from the roller 2. A support member 34 is provided on the side of the shelf 33 facing the roller 2, which can provide support for the shelf 33, reduce the possibility of deformation of the shelf 33, and improve the reliability of the shelf layer 3.

[0089] like Figure 6 and Figure 10As shown, a baffle 35 is provided on the side of the shelf 33 away from the support member 34, and the baffle 35 is located at the edge of the shelf 33.

[0090] The material is placed on the side of the shelf 33 away from the support member 34. A baffle 35 is provided at the edge of the shelf 33 to reduce the possibility of the material slipping off the edge of the shelf 33, which helps to improve the stability of the transport vehicle during the transfer process.

[0091] In one possible embodiment, the projection of the baffle 35 is within the projection range of the frame 36 in the direction where the roller 2 points toward the shelf 33.

[0092] The baffle 35 can be connected to the frame 36 by screws. The screws can pass through the edge of the shelf 33, so that the edge of the shelf 33 is clamped between the baffle 35 and the frame 36, reducing the possibility of the edge of the shelf 33 warping.

[0093] like Figure 10 As shown, in one possible embodiment, at least one side of the first type of storage layer 31 is provided with a handle 6 along the movement direction perpendicular to the second type of storage layer 32, and the staff can drive the transport vehicle to move by means of the handle 6.

[0094] When the staff pushes or pulls the transport vehicle with handle 6, the transport vehicle moves in the second direction, which is perpendicular to the first direction. During the movement of the transport vehicle, the possibility of materials falling or the transport vehicle overturning due to the second type of storage layer 32 protruding into the accommodating space 14 is reduced, thus improving the reliability of the transport vehicle during the transportation process.

[0095] like Figure 10 and Figure 11 As shown, in one possible embodiment, a second mounting member 312 is provided on the side of the first type of shelf 31 near the second type of shelf 32, and a handle 6 is rotatably mounted on the second mounting member 312. The handle 6 includes a connecting part 61, which is rotatably connected to the second mounting member 312, allowing the operator to adjust the rotation angle of the handle 6 according to height requirements.

[0096] The second mounting member 312 is clamped between the two sides of the connecting part 61, so that the second mounting member 312 contacts the connecting part 61 and has a large friction force, providing damping for the handle 6, so that the handle 6 can be suspended at any angle. During transportation, it can reduce the possibility of the handle 6 swaying relative to the bracket 1, which is beneficial to improving the stability during the transfer process.

[0097] like Figure 1 As shown, in one possible embodiment, the transport vehicle includes a top cover 5 located on the side of the first type of storage layer 31 away from the second type of storage layer 32, and mounted on the end of the bracket 1 away from the roller 2.

[0098] The material is placed on the side of the first type of storage layer 31 away from the second type of storage layer 32. The top cover 5 is located on the side of the first type of storage layer 31 away from the roller. This can reduce the possibility of the material on the surface of the first type of storage layer 31 being impacted. The top cover 5 can also limit the height of the material that can be placed on the surface of the first type of storage layer 31, reduce the possibility of the material falling due to excessive stacking, and improve the safety during the material transfer process.

[0099] like Figure 1 As shown, the side of the top cover 5 away from the storage layer 3 is an arc-shaped surface, which can reduce the possibility of materials being impacted or falling when placed on the surface of the top cover 5, and can also reduce the possibility of overloading the transport vehicle and improve the service life of the transport vehicle.

[0100] like Figure 1 As shown, in one possible embodiment, a plurality of connecting posts 16 are provided between the top cover 5 and the first type of storage layer 31. One end of the connecting post 16 is connected to the frame 36 of the first type of storage layer 31, and the other end is connected to the top cover 5, which can improve the stability of the top cover 5 after installation.

[0101] Along the second direction, multiple connecting posts 16 are respectively arranged on both sides of the first type of storage layer 31, so that the connecting posts 16 and the handle 6 are located on the same side of the first type of storage layer 31. When the staff pulls the transport vehicle through the handle 6, the position of the materials on the first type of storage layer 31 can be restricted, reducing the possibility of materials falling off the first type of storage layer 31 due to inertia.

[0102] Materials on the second placement layer can be accessed from the side where the second type of placement layer 32 is pulled out, and materials on the first type of placement layer 31 can be accessed from the side of the first type of placement layer 31 where the connecting post 16 is not provided. The second type of placement layer 32 is pulled out along the first direction, and the connecting post 16 is provided on both sides of the second direction, which is perpendicular to the first direction. This allows materials on the first placement layer and materials on the second type of placement layer 32 to be accessed from the same side, thereby improving the efficiency of material access.

[0103] like Figure 6 and Figure 10 As shown, in one possible embodiment, the transport vehicle includes at least one first information code 7 and / or at least one second information code 8. When the transport vehicle includes at least one first information code 7, the at least one first information code 7 is disposed on the edge 36 of the first type of storage layer 31 and / or the edge 36 of the second type of storage layer 32, and is located on the side of the edge 36. When the transport vehicle includes at least one second information code 8, the at least one second information code 8 is disposed on the edge 36 of the first type of storage layer 31 and / or the edge 36 of the second type of storage layer 32, and is located on the side of the edge.

[0104] Materials are placed on storage layer 3 via a transfer tray, and the position of at least one first information code 7 corresponds to the position of the transfer tray. Workers can bind material information to the transport vehicle by scanning the first information code 7, facilitating intelligent management of the materials.

[0105] The second information code 8 can store the identity and location information of the transport vehicle. By scanning the second information code 8 and the location code on the ground, the staff can bind the transport vehicle to the location code on the ground. If the transport vehicle needs to be driven by an AGV, the AGV can move to the corresponding position according to the location information in the second information code 8, such as below or to the side of the transport vehicle, and drive the transport vehicle to the designated position.

[0106] like Figure 2 As shown, in one possible embodiment, the bracket 1 includes a plurality of support beams 12 located on the side of the bracket 1 near the roller 2, and the plurality of support beams 12 are arranged crosswise.

[0107] To illustrate, the AGV drives the transport vehicle from below. The AGV moves to the side of the transport vehicle where the rollers 2 are located, and then the AGV's drive rod is raised so that it can abut against the intersection of multiple support beams 12, so that the AGV can drive the transport vehicle to the designated position.

[0108] After the AGV moves to the side of the transport vehicle equipped with rollers 2, it needs to scan the second information code 8 to confirm the transport vehicle to be driven, and then drive the transport vehicle to move. For example... Figure 6 As shown, a second information code 8 is provided on the side of the second type of storage layer 32 near the roller 2. When the AGV moves to the side of the transport vehicle where the roller 2 is located, the second type of storage layer 32 protrudes from the receiving space 14. The second information code 8 located on the side of the second type of storage layer 32 near the roller 2 will shift position along with the second type of storage layer 32, causing the AGV to be unable to scan the second information code 8. This reduces the possibility of the transport vehicle being driven when the second type of storage layer 32 protrudes from the receiving space 14, which helps to improve the reliability of the transport vehicle during transportation.
