[0032] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0033] See Figures 1-2This invention provides an adjustable AGV transfer vehicle, including an AGV vehicle body 1. The rear end of the AGV vehicle body 1 has a vehicle plate 11, which is a horizontally arranged plate structure. The AGV vehicle body 1 is prior art; for details, please refer to the specification in Chinese Patent Publication No. CN109878406B, which will not be described in detail here. A support seat 2 is fixed to the top surface of the vehicle plate 11. A first support plate 3 and a second support plate 4 are rotatably mounted at both ends of the top surface of the support seat 2. Specifically, rotating seats are provided at both ends of the top surface of the support seat 2, and the bottom ends of the first support plate 3 and the second support plate 4 are rotatably connected to the two rotating seats.

[0034] When the first support plate 3 and the second support plate 4 are rotated inward to a horizontal state, the first support plate 3 and the second support plate 4 together support the plate-shaped object; when the first support plate 3 and the second support plate 4 are rotated outward to an open state, a receiving chamber is formed between the first support plate 3, the second support plate 4 and the support seat 2, and the receiving chamber is used to receive the cylindrical object.

[0035] In use, when transferring plate-shaped materials, the operator can rotate the first support plate 3 and the second support plate 4 inward to a horizontal position, forming a horizontal support plane between their top surfaces. The plate-shaped material can then be placed on this plane for transfer. When transferring cylindrical materials, the operator can rotate both the first support plate 3 and the second support plate 4 outward to an open position, forming a receiving chamber between them and the support base 2. The cylindrical material can then be placed inside this chamber for transfer. In other words, by adjusting the position of the first support plate 3 and the second support plate 4, this device can transfer both plate-shaped and cylindrical materials, improving its adaptability.

[0036] See Figures 3-5 The top surface of the support seat 2 is provided with a first support groove 55, the inner side of the first support plate 3 is provided with a second support groove 32, and the inner side of the second support plate 4 is provided with a third support groove 4. The first support groove 55, the second support groove 32 and the third support groove 4 together form a cylindrical cavity.

[0037] In this device, the first bearing groove 55, the second bearing groove 32, and the third bearing groove 4 are all arc-shaped surface structures. During use, when the first bearing plate 3 and the second bearing plate 4 are rotated outwards to open, the first bearing plate 3 drives the second bearing groove 32 to rotate outwards, and the second bearing plate 4 drives the third bearing groove 4 to rotate outwards, so that the first bearing groove 55, the second bearing groove 32, and the third bearing groove 4 are located within the same cylindrical surface, forming a cylindrical chamber. Workers can place cylindrical materials inside the cylindrical chamber, improving the adaptability of the transfer vehicle. Furthermore, the first bearing plate 3 and the second bearing plate 4 can also block cylindrical materials from both sides, preventing them from rolling during transfer and improving transportation safety.

[0038] See Figures 3-7 The support base 2 has a height-adjustable support mechanism at its inner bottom. When the first support plate 3 and the second support plate 4 are in a horizontal state, the top of the support mechanism supports the bottom surfaces of the first support plate 3 and the second support plate 4. Specifically, the support mechanism includes an electric telescopic rod 52 and a support plate 5. An installation cylinder 51 is fixed to the bottom surface of the support base 2. The electric telescopic rod 52 is vertically installed inside the installation cylinder 51, and the support plate 5 is horizontally fixed to the top of the electric telescopic rod 52. The first support plate 3 has a first support groove 31 at its inner bottom surface, and the second support plate 4 has a second support groove 41 at its inner bottom surface. The support plate 5 supports the first support groove 31 and the second support groove 41.

[0039] During use, when the first bearing plate 3 and the second bearing plate 4 are rotated to a horizontal position, the electric telescopic rod 52 is activated and extended. The top of the electric telescopic rod 52 moves upward, which in turn drives the support plate 5 to move upward. When the support plate 5 just contacts and supports the first support groove 31 and the second support groove 41, the extension of the electric telescopic rod 52 stops, so that the top of the electric telescopic rod 52 stably supports the first support groove 31 and the second support groove 41 through the support plate 5. This makes the first bearing plate 3 and the second bearing plate 4 stably positioned in a horizontal position, thereby enabling the first bearing plate 3 and the second bearing plate 4 to stably support the plate-shaped material and improve the stability of the transfer operation.

[0040] See Figure 3 , 4 A receiving groove 53 is provided at the middle position of the top surface of the bearing seat 2. When the electric telescopic rod 52 is shortened to its shortest state, the receiving groove 53 can accommodate the support plate 5.

[0041] During use, when both the first bearing plate 3 and the second bearing plate 4 are rotated outward to the open state, the electric telescopic rod 52 is activated and shortened. The top of the electric telescopic rod 52 drives the support plate 5 to move downward and retract the support plate 5 into the receiving groove 53, so that the top surface of the support plate 5 is lower than the top surface of the first bearing groove 55, thereby completely exposing the first bearing groove 55. This prevents the support plate 5 from obstructing the cylindrical material, ensures good contact between the bottom surface of the cylindrical material and the first bearing groove 55, increases the contact area, reduces pressure, and protects the surface of the cylindrical material.

[0042] See Figure 7 A first torsion spring 61 is provided between the rotating end of the first bearing plate 3 and the left end of the top surface of the bearing seat 2, and a second torsion spring 62 is provided between the rotating end of the second bearing plate 4 and the right end of the top surface of the bearing seat 2.

[0043] In use, when it is necessary to transfer plate-shaped materials, the first bearing plate 3 rotates inward to a horizontal position under the torque of the first torsion spring 61. Simultaneously, the second bearing plate 4 rotates inward to a horizontal position under the torque of the second torsion spring 62. That is, the first torsion spring 61 and the second torsion spring 62 simultaneously rotate the first bearing plate 3 and the second bearing plate 4 to a horizontal position. This is the default state of the device, requiring no external force from the operator to rotate the first bearing plate 3 and the second bearing plate 4 inward, saving effort and simplifying operation. Furthermore, when the operator moves the first bearing plate 3 and the second bearing plate 4... After plate 4 opens outward and the cylindrical material is placed into the first bearing groove 55, the first bearing plate 3 and the second bearing plate 4 are released. Under the torsion of the first torsion spring 61 and the second torsion spring 62, the first bearing plate 3 and the second bearing plate 4 rotate inward. The first bearing plate 3 and the second bearing plate 4 rotate to contact the surface of the cylindrical material. The first bearing plate 3 and the second bearing plate 4 respectively provide inward clamping force to the surface of the cylindrical material, so as to stably clamp the cylindrical material, avoid the cylindrical material from shaking during the transfer, and improve the safety of the transfer.

[0044] See Figure 8 A photoelectric transmitter 71 is installed in the cavity at the free end of the first support plate 3, and a photoelectric receiver 72 is installed in the cavity at the free end of the second support plate 4. When both the first support plate 3 and the second support plate 4 are in a horizontal position, the photoelectric transmitter 71 and the photoelectric receiver 72 correspond to each other. A pressure sensor is provided between the bottom end of the electric telescopic rod 52 and the inner bottom surface of the mounting cylinder 51. (See also...) Figure 9 It also includes a control module, and the photoelectric transmitter 71, photoelectric receiver 72, electric telescopic rod 52, and pressure sensor are all electrically connected to the control module.

[0045] In operation, when transferring plate-shaped materials, the first support plate 3 and the second support plate 4 are first rotated to a horizontal position, at which point the photoelectric transmitter 71 and the photoelectric receiver 72 are facing each other. When the photoelectric receiver 72 receives the photoelectric signal emitted by the photoelectric transmitter 71, the control module controls the electric telescopic rod 52 to extend upwards. The top of the electric telescopic rod 52 drives the support plate 5 to move upwards. When the pressure sensor detects an increase in pressure, the top surface of the support plate 5 just touches the first support groove 31 and the second support groove 41. The control module then controls the electric telescopic rod 52 to stop extending, so that the support plate 5 is in a position that just supports the first support plate 3 and the second support plate 4. When the photoelectric receiver 72 does not receive a signal, the first support plate 3 and the second support plate 4 are not in a horizontal position, indicating that the operator is preparing to transfer cylindrical materials. The control module then controls the electric telescopic rod 52 to shorten downwards, retracting the support plate 5 into the receiving groove 53 to accommodate the cylindrical materials. The entire operation is automated, quick, convenient, and improves work efficiency.

[0046] The above are merely embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
