[0002] Building formwork is a temporary supporting structure, whose main purpose is to ensure the quality and construction safety of concrete projects, while speeding up construction progress and reducing project costs. When storing building formwork, it can be stored in a highly integrated three-dimensional warehouse. The three-dimensional warehouse stores goods through shelves that are several, dozens or even dozens of layers high, and can store building formwork with high space utilization.
[0003] In order to overcome the above-mentioned defects, the prior art 1 (a Chinese patent with announcement number CN215324863U and announcement date of 2021-12-28) is a three-dimensional warehouse. The three-dimensional warehouse includes a warehouse body and a loading device, the warehouse body is provided with a loading channel, and the loading channel is provided with a slide rail; the loading device includes a loading vehicle slidably mounted on the slide rail, the loading vehicle includes a bottom plate, a mounting frame mounted on the bottom plate, and a receiving assembly mounted on the edge of the mounting frame, the mounting frame includes an extension leg connected to the top surface of the bottom plate and a hollow frame connected to the extension leg, so that a loading space is formed between the bottom plate and the hollow frame, the horizontal column is parallel to the bottom plate and extends to a direction away from the hollow frame, the horizontal column and the vertical column are both retractable, and the three-dimensional warehouse can prevent items from falling and protect items from damage.
[0004] There is also prior art 2 (a Chinese patent with announcement number CN212221320U and announcement date of 2020-12-25), a three-dimensional warehouse, whose factory building includes factory building columns, equipment, a top conveyor vehicle, items, a three-dimensional warehouse and tracks. The equipment and the three-dimensional warehouse are both located below the tracks. The top conveyor vehicle includes a walking device and a vehicle body. The vehicle body includes a frame, columns, a cavity, a lifting and hoisting device and a picking and placing device. The cavity opening downward is the bottom space in the frame; the three-dimensional warehouse includes three-dimensional shelves, aisles, stackers and conveying devices. A conveying vehicle is used to increase the channel for entering and exiting the warehouse on the top floor. By arranging a conveying device in the three-dimensional shelves for direct entry and exit of the warehouse, the entry and exit of the three-dimensional warehouse is smoother and more efficient; the items are directly transported from the warehouse to the equipment, reducing the transfer links.
[0005] Although the existing stereoscopic warehouse can store objects with high efficiency, it is impossible to limit the placement of objects when placing them on the warehouse shelves. The objects are easily placed offset, resulting in unstable placement of objects and posing certain safety hazards.
[0006] Therefore, we propose a three-dimensional warehouse for storing building templates in order to solve the problems mentioned above. Summary of the invention

[0009] Preferably, a motor is fixedly connected to the side of the limiting frame, and the output end of the motor is fixedly connected to the end side of the rotating shaft, and a first bevel gear is fixedly connected to the outer side of the rotating shaft.
[0010] Preferably, a threaded rod is vertically nested and connected to the inner side of the limiting frame, and the end of the threaded rod is fixedly connected to the second bevel gear, and the second bevel gear and the first bevel gear are meshed with each other.
[0011] Preferably, the auxiliary limiting mechanism includes a fixed shaft, which is fixedly connected to the inside of the limiting frame, the movable box is threadedly connected to the outside of the threaded rod, and the movable box is also nested and connected to the outside of the fixed shaft, and fixed magnetic blocks are arranged at equal intervals on the fixed shaft, a movable groove is opened inside the movable box, and the inside of the movable box is nested and connected to the limiting rod, and one end of the limiting rod is fixedly connected to a movable plate, and the other end of the movable plate is fixedly connected to a connecting block, an auxiliary magnetic block is fixedly connected to the inner side of the connecting block, and a first spring is fixedly connected between the connecting block and the inner wall of the movable groove, an auxiliary plate is fixedly connected to the movable plate close to the inner side of the movable plate, and a resistance plate is fixedly connected to the outer side of the auxiliary plate.
[0012] Preferably, the auxiliary magnetic block and the fixed magnetic block have opposite magnetism, the connecting block forms an elastic structure with the inner wall of the movable groove through the first spring, the movable plate forms a sliding structure with the movable groove through the limiting rod, and the auxiliary plate forms a sliding structure with the movable plate and the movable box.
[0013] Preferably, a knocking plate is fixedly connected to one side of the movable plate close to the outer side of the movable plate, and a resistance block is fixedly connected to the outer side of the knocking plate. The movable box is arranged in an "L" shape, and the movable box forms a sliding structure with the fixed shaft through a threaded rod.
[0014] Preferably, an extrusion plate is nested and connected to the connecting plate, and the extrusion plate is arranged in an inverted "L" shape when viewed from the side, the front side of the connecting plate is fixedly connected to a guide rod, the lower side of the extrusion plate is nested and connected to the outer side of the guide rod, and a second spring is fixedly connected between the inner side of the extrusion plate and the connecting plate.
[0015] Preferably, an adjustment groove is opened on the extrusion plate, and an auxiliary rod is fixedly connected to the inside of the adjustment groove, and a rotating plate is nested and connected to the outside of the auxiliary rod, and a third spring is fixedly connected between the outside of the rotating plate and the inner wall of the adjustment groove.
[0016] Preferably, the rotating plate is arranged in an inclined zigzag structure in a side view, and is located directly above the extrusion plate, and the rotating plate forms a rotating structure with the auxiliary rod through the resistance of the extrusion plate, and the rotating plate forms an elastic structure with the auxiliary rod through a third spring.
[0017] Compared with the prior art, the present invention has the following beneficial effects: There are multiple groups of limit frames arranged inside the warehouse frame, through which the building templates can be separated and placed individually, reducing the phenomenon that multiple building templates are stacked together, which is inconvenient for subsequent retrieval. At the same time, there is a certain distance between each limit frame, so that when the building template is placed, the contact area between the board and the air is larger, reducing the possibility of moisture between the boards when they are stacked.
[0018] Auxiliary rollers are arranged on the front side of the limiting frame. When the building template is transported to the front end of the limiting frame and contacts the auxiliary rollers via the conveying mechanism, the motor is started. At this time, the motor drives the auxiliary rollers to rotate through the rotating shaft. At this time, the auxiliary rollers can drive the building template to move through the friction force, so that the building template can be placed inside the limiting frame by itself, thereby reducing the conveying time of the conveying mechanism for the building template and further improving the storage efficiency of the building template.
[0019] When the rotating shaft rotates under the driving action of the motor, the threaded rod can be driven to rotate synchronously through the meshing action between the first bevel gear and the second bevel gear arranged on its end side. At this time, the moving box can slide along the fixed shaft under the threaded connection with the threaded rod. When the moving box slides, it can synchronously drive the resistance plate to slide. The resistance plate can limit the side of the building template transported by the auxiliary roller, so that the building template can be stably transported to the inside of the limiting frame, reducing the possibility of positional displacement of the building template during transportation.
[0020] When the movable box slides, the connecting block arranged inside will slide synchronously. At this time, the auxiliary magnetic block arranged on the inner side of the connecting block will indirectly contact the fixed magnetic block arranged on the outer side of the fixed shaft. Driven by the magnetic force between the fixed magnetic block and the auxiliary magnetic block, the connecting block can push the movable plate to move through the limiting rod. When the two groups of magnetic blocks do not interact with each other, the connecting block can be reset by the elastic force of the first spring, so that the movable plate can reciprocate inside the movable groove. At this time, the movable plate can drive the resistance plate to move back and forth through the auxiliary plate, thereby knocking and slapping the side of the building formwork plate body, thereby improving the limiting effect of the building formwork. At the same time, when the movable plate moves, it can synchronously drive the knocking plate to move, so that the knocking plate drives the resistance block to knock on the limiting frame, causing the limiting frame to vibrate, and further enables the auxiliary plate to better adjust the position of the building formwork.
[0021] When the building formwork is transported to the interior of the limiting frame, the end side of the building formwork will come into conflict with the extruded plate nested and connected on the connecting plate, causing the extruded plate to move backward. At this time, the extruded plate can come into conflict with the rotating plate, causing the rotating plate to rotate along the auxiliary rod. When the rotating plate rotates, its front end comes into conflict with the building formwork, thereby limiting the building formwork and further ensuring the stability of the placement of the building formwork.

[0026] A plurality of limit frames 2 are arranged inside the warehouse frame 1, through which the building templates can be separated and placed individually, thereby reducing the phenomenon that multiple building templates are stacked together, which is inconvenient for subsequent retrieval. At the same time, there is a certain distance between each limit frame 2, so that when the building template is placed, the contact area between the plate body and the air is larger, thereby reducing the possibility of moisture between the plates when the plates are stacked. Auxiliary rollers 3 are arranged on the front side of the limit frame 2. When the building template is transported to the front end of the limit frame 2 via the conveying mechanism and contacts with the auxiliary rollers 3, the motor 6 is started. At this time, the motor 6 drives the auxiliary rollers 3 to rotate through the rotating shaft 7. At this time, the auxiliary rollers 3 can drive the building template to move through the friction force, so that the building template can be placed inside the limit frame 2 by itself, thereby reducing the conveying time of the conveying mechanism for the building template, and further improving the storage efficiency of the building template.
[0027] Embodiment 2: Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9The technical scheme shown in the figure, the present invention provides the following technical scheme: a three-dimensional warehouse for storing building templates, discloses an auxiliary limiting mechanism, through which the position of the transported building template can be adjusted to prevent the position of the building template from shifting: the front side of the limiting frame 2 is laterally nested with a rotating shaft 7, and the outer side of the rotating shaft 7 is fixedly connected with an auxiliary roller 3, and an auxiliary limiting mechanism is arranged between the end side of the rotating shaft 7 and the limiting frame 2, the auxiliary limiting mechanism limits the placed building template through the moving action of the moving box 5 arranged inside it, the auxiliary limiting mechanism includes a fixed shaft 11, the fixed shaft 11 is fixedly connected to the inside of the limiting frame 2, the moving box 5 is threadedly connected to the outer side of the threaded rod 9, and the moving box 5 is simultaneously nested and connected to the outer side of the fixed shaft 11, and fixed magnetic blocks 12 are arranged on the fixed shaft 11 at equal intervals, a movable groove 13 is opened inside the moving box 5, and the inner part of the moving box 5 is nested and connected with a limiting rod 18, and the limiting rod 1 One end of 8 is fixedly connected to a movable plate 22, and the other end of the movable plate 22 is fixedly connected to a connecting block 20, an auxiliary magnetic block 21 is fixedly connected to the inner side of the connecting block 20, and a first spring 19 is fixedly connected between the connecting block 20 and the inner wall of the movable groove 13, the movable plate 22 is fixedly connected to an auxiliary plate 14 near the inner side of the movable plate 22, and a resistance plate 15 is fixedly connected to the outer side of the auxiliary plate 14, the magnetic properties of the auxiliary magnetic block 21 and the fixed magnetic block 12 are opposite, the connecting block 20 forms an elastic structure with the inner wall of the movable groove 13 through the first spring 19, the movable plate 22 forms a sliding structure with the movable groove 13 through the limiting rod 18, the auxiliary plate 14 forms a sliding structure with the movable box 5 through the movable plate 22, the movable plate 22 is fixedly connected to a knocking plate 16 near the outer side of the movable plate 22, and a resistance block 17 is fixedly connected to the outer side of the knocking plate 16, the movable box 5 is arranged in an "L" shape, and the movable box 5 forms a sliding structure with the fixed shaft 11 through the threaded rod 9.
[0028] When the rotating shaft 7 rotates under the driving action of the motor 6, the threaded rod 9 can be driven to rotate synchronously through the meshing action between the first bevel gear 8 and the second bevel gear 10 arranged on its end side. At this time, the moving box 5 can slide along the fixed shaft 11 under the threaded connection with the threaded rod 9. When the moving box 5 is sliding, it can synchronously drive the contact plate 15 to slide. The contact plate 15 can limit the side of the building template transported by the auxiliary roller 3, so that the building template can be stably transported to the inside of the limiting frame 2, reducing the possibility of positional deviation of the building template during transportation. When the moving box 5 slides, the connecting block 20 arranged inside will slide synchronously. At this time, the auxiliary magnetic block 21 arranged on the inner side of the connecting block 20 will indirectly contact the fixed magnetic block 12 arranged on the outer side of the fixed shaft 11. Driven by the magnetic force between the fixed magnetic block 12 and the auxiliary magnetic block 21, the connecting block 20 can push the movable plate 22 to move through the limiting rod 18. When the two groups of magnetic blocks do not interact with each other, the elastic force of the first spring 19 can drive the connecting block 20 to reset, so that the movable plate 22 can reciprocate inside the movable groove 13. At this time, the movable plate 22 can drive the resistance plate 15 to move back and forth through the auxiliary plate 14, thereby knocking and slapping the side of the building formwork plate body to improve the limiting effect of the building formwork.
