The width of the auxiliary crossbeam 2 is less than or equal to the width of the crossbeam 1. The top surfaces of the crossbeam 1, the auxiliary crossbeam 2, and the main connecting beam 3 are flush.

[0033] Referring to Figure 3 The material tray comprises a tray 12 and a support beam 13. The support beam 13 is arranged parallel to the crossbeam 1 and the auxiliary crossbeam 2.

The support beams 13 are arranged at certain intervals, and the total number of the support beams 13 is greater than or equal to the total number of the crossbeam 1 and the auxiliary crossbeam 2. The support beams 13 are arranged at the bottom of the material tray. The interval between the support beams 13 can be docked with the automated guided vehicle. The automated guided vehicle needs to cooperate with the material tray. A plurality of protruding parts are arranged on the lifting disc of the automated guided vehicle to abut against the bottom position of the tray 12 between the adjacent support beams 13 at the bottom of the material tray, for automatic transportation. In addition, the support beams 13 provide sufficient space for the forks of the forklift. When it is inconvenient to use the automated guided vehicle for transportation, the forklift can also be used directly for transportation, meeting the demand of forklift transfer in special situations.

The length of the support beam 13 is greater than the length of the auxiliary crossbeam 2 and less than the length of the crossbeam 1. The width of the support beam 13 is less than the width of the auxiliary crossbeam 2.

[0035] The top of the tool support of the embodiment is an open rectangular frame structure. When the building heavy material needs to be transported to the production line, the material tray with the building heavy material can be directly transported to the tool support by using the automatic guided vehicle. The material tray can be placed on the tool support by falling the lifting disc of the automatic guided vehicle. When the material tray is placed on the tool support, the auxiliary cross beam 2 and the auxiliary support column 6 can further disperse the pressure on the tool support without affecting the operation of the automatic guided vehicle, thereby improving the overall load capacity of the line edge storage support.

[0036] Preferably, the middle part of the cross beam 1 is also connected with a vertical downward column 4. The columns 4 connected with the same cross beam 1 and the support columns 5 and the columns 4 are provided with bottom connecting beams 10.

The bottom connecting beams can enhance the ability of the tool support to resist lateral force, so that the structure is not easy to deform. More columns can enhance the load capacity of the tool support.

[0037] Preferably, the auxiliary support column 6 is vertically arranged relative to the main connecting beam 3. The bottom connecting beam 10 is arranged in parallel with the main connecting beam 3 or the cross beam 1. The top of the column 4 is fixedly connected with the bottom of the cross beam 1. The top of the support column 5 is fixedly connected with the cross beam 1. The two ends of the main connecting beam 3 are respectively fixedly connected with the cross beam 1. The auxiliary cross beam 2 is fixedly connected with the side of the main connecting beam 3. The top of the auxiliary support column 6 is fixedly connected with the bottom of the main connecting beam 3. The tool support is a steel or wooden support.

[0038] The connection modes between the above-mentioned various connection parts include bolt connection, rivet connection, mortise and tenon connection or welding connection for different materials.

[0039] The steel support has higher load capacity and structural strength, stronger applicability, and can store relatively more and heavier building heavy materials for a long time. Compared with the steel support, the wooden support has lower load capacity and structural strength, lower cost and lighter weight, and is more suitable for storing relatively less and lighter building heavy materials or temporary storage.

[0040] More preferably, in this embodiment, the tooling support is a steel structure; the top of the stand column 4 is welded to the bottom of the cross beam 1; the top of the support column 5 is welded to the cross beam 1; the two ends of the main connecting beam 3 are welded to the sides of the cross beam 1; the auxiliary cross beam 2 is welded to the side of the main connecting beam 3; and the top of the auxiliary support column 6 is welded to the bottom of the main connecting beam 3.

[0041] It should be additionally noted that the tooling support and the material pallet of this embodiment need to be adapted to the unmanned carrier vehicle. Matters needing attention in the adaptation include that the width between the cross beams 1 and the length of the main connecting beam 3 are greater than the width of the unmanned carrier vehicle, the length of the cross beam 1 is greater than the length of the unmanned carrier vehicle, and the unmanned carrier vehicle can be completely parked at the bottom of the tooling support, etc. These matters need to be determined according to the actual situation and belong to routine technical adjustment, which will not be described here.

Different numbers of the stand column 4, the auxiliary support column 6 and the auxiliary cross beam 2 can be selected according to different target load capacities, and different lengths and specifications of the main connecting beam 3 or the cross beam 1 can be selected to cooperate with them.

[0043] More preferably, in this embodiment, the stand column 4 has four, the auxiliary support column 6 and the auxiliary cross beam 2 each have two; and the support beam 13 has four.

[0044] Preferably, the bottom ends of the stand column 4, the support column 5 and the auxiliary support column 6 are respectively provided with a support base 11.

[0045] Compared with the bottom area of the stand column 4, the support column 5 and the auxiliary support column 6, the bottom area of the support base 11 is larger, which can disperse the pressure of the tooling support on the bottom surface, prevent the tooling support from damaging the ground, and enhance the stability of the tooling support; the support base 11 is a wooden base, a plastic base or a steel base.

[0046] More preferably, in this embodiment, the support base 11 is a steel base, and the stand column 4, the support column 5 and the auxiliary support column 6 are welded to the support base 11.

[0047] Preferably, the cross beam 1 is further provided with a baffle 8; the baffle 8 is arranged on the outer side of the cross beam 1 away from the open rectangular frame, and is used to limit the left and right positions of the material tray, so as to prevent the material tray from being overlapped on the top of the tool support, and then sliding left and right when subjected to external force interference (such as taking or adding building heavy materials on the material tray), and causing the material tray to slide and overturn; the top of the baffle 8 is inclined, which can ensure that the supporting beam 13 of the material tray can be overlapped on the tool support, prevent the AGV from deviating during placing or transporting the material tray, and cause the material tray to fall on the tool support, and provide more fault tolerance for automatic operation.

[0048] Preferably, the main connecting beam 3 is further provided with a blocking beam 7; the blocking beam 7 extends to the top of the auxiliary cross beam 2 near one side of the open rectangular frame; the blocking beam 7 is fixedly connected with the main connecting beam 3 and the auxiliary cross beam 2; the blocking beam 7 is used to limit the front and rear positions of the material tray.

[0049] The blocking beam 7 is used to limit the position of the material tray, so as to prevent the AGV from being not accurately positioned or not timely stopped, and part of the material tray protruding from the rear side of the tool support, affecting the operation of the production line and causing safety hazards; at the same time, the blocking beam 7 extends to the top of the auxiliary cross beam 2 near one side of the open rectangular frame, which can completely cover the connection between the main connecting beam 3 and the auxiliary cross beam 2, enhance the connection strength of the connection, and protect the connection from being damaged by repeated friction of the material tray during continuous use, and cause the carrying capacity to decrease.

[0050] Preferably, the length of the blocking beam 7 is greater than the length of the main connecting beam 3; the two ends of the blocking beam 7 are fixedly connected with the cross beam 1 respectively; the side surface of the blocking beam 7 near one side of the open rectangular frame is provided with an inclined surface; the inclined surface is inclined away from the open rectangular frame.

[0051] The longer blocking beam 7 is connected to the cross beam 1, which can further strengthen the structural strength of the tool support, enhance the ability to resist lateral force, prevent deformation and tilting when subjected to large vertical (vertical) pressure from building heavy materials; At the same time, the longer blocking beam can also cover the top of the connection between the main connecting beam and the cross beam, protect the connection, prevent the connection between the main connecting beam and the cross beam from being damaged; The side surface close to one side of the open rectangular frame is provided with an inclined surface, which can further ensure that the support beam 13 of the material tray can be overlapped on the tool support, prevent the automated guided vehicle from incorrectly overlapping the support beam 13 of the material tray on the blocking beam 7 when the transportation positioning recognition is not accurate or the stop is not timely, and cause the building heavy material to fall off the material tray, and provide more fault tolerance space for automatic operation.

[0052] Preferably, the auxiliary cross beam 2 is fixedly connected with a reinforcing plate 9 close to one side of the open rectangular frame; the top of the reinforcing plate 9 is fixedly connected with the bottom of the auxiliary support column 6.

[0053] The reinforcing plate 9 is arranged between the auxiliary cross beam 2 and the auxiliary support column 6, which can directly conduct part of the pressure received by the auxiliary cross beam 2 to the auxiliary support column 6, reduce the stress received by the connection between the auxiliary cross beam 2 and the main connecting beam 3, and enhance the carrying capacity of the tool support as a whole; wherein the reinforcing plate 9 cannot be too large, so as to prevent it from affecting the operation of the automated guided vehicle and making the automated guided vehicle unable to normally park at the bottom of the tool support.

[0054] Preferably, the material tray is a steel structure or a wooden structure.

[0055] More preferably, in the embodiment, the material tray is a steel structure.

[0056] Preferably, the top of the tray 12 is provided with a rough surface; the bottom of the tray 12 is also provided with a reinforcing rib 14.

[0057] The rough surface can enhance the friction between the building heavy material and the material tray, so that the building heavy material can be stably stored on the material tray during transportation and storage; the reinforcing rib 14 can enhance the carrying capacity of the material tray itself, and prevent the tray 12 from being broken.

[0058] It needs to be additionally explained that since the running speed of the automated guided vehicle is not fast and the overall transportation process is relatively stable, the steel structure such as steel keel, the wood structure such as solid wood wall and the prefabricated concrete such as prefabricated reinforced concrete beam and other heavy materials of fabricated building can be stable during the transportation process without other fixing measures. Even if the circular tubular material is transported, it can also be stably stored on the in-line storage tray 12 after being fixed by the rope.

[0059] In summary, the building material tool support for the automated guided vehicle in the embodiment can be automatically, safely and stably transported to the production line in cooperation with the automated guided vehicle, is more suitable for the automatic taking and placing of the heavy building materials and is beneficial to the automatic operation. In addition, the material tray with relatively uniform specifications is used to combine the support beam 13 and the tray 12. Compared with the prior art, the adaptability of the material tray is higher. The tray 12 can meet the storage needs of various heavy building materials, and the management is more convenient and is not prone to the phenomenon of management confusion caused by too many support specifications. Moreover, the addition of the support beam 13 can be connected with the automated guided vehicle for automatic transportation and can meet the demand of forklift transfer in special cases, having high practicality and flexibility. At the same time, the vertical column 4, the auxiliary cross beam 2 and the auxiliary support column 6 are arranged to further improve the carrying capacity and stability of the tool support as a whole without affecting the running of the automated guided vehicle, so that the heavy building materials can be stably stored for a long time and the storage needs of the heavy building materials of the fabricated building factory can be met.
