Description

Technical Field

[0001] This utility model relates to the technical field of storage devices, and specifically to a material storage structure. Background Technology

[0002] Raw material yards are the core hubs for ensuring the smooth operation of processes such as sintering, ironmaking, and steelmaking. With the implementation of shed-style and warehouse-style transformation of raw material yards to solve the dust pollution problem caused by open-air storage, this move has promoted large-scale material yard enclosure projects in steel enterprises. The most common method is to use steel structures to build arched sheds for material yard enclosure transformation.

[0003] However, traditional steel-structured arched greenhouses have the following problems: 1. Steel structures require very deep pile foundations to effectively transfer loads, resulting in a very long construction period; 2. The renovation will cause the material yard to shut down, which will lead to the interruption of material balance, unstable raw material supply for subsequent processes, and increased costs. 3. Enclosed structures located in the material yard will occupy a certain amount of space in the material yard, which will lead to a significant decrease in storage capacity. Summary of the Invention

[0004] This utility model addresses the aforementioned problems and aims to provide a material storage structure with a short construction period, allowing for modifications without interrupting production, while simultaneously increasing storage capacity.

[0005] To achieve the above objectives, this utility model provides a material storage structure for storing materials in a material yard, the material storage structure comprising: An air-supported membrane assembly includes an air-supported membrane body that covers the material yard and forms an arched enclosed space by internal inflation; A strip assembly includes a strip located within the enclosed space and a retaining wall. The material yard has a recessed area, the strip is located within the recessed area, and the retaining wall is located on both sides of the strip. A stacking and retrieving assembly includes a stacker located within the enclosed space, the stacker being movably disposed on one side of the material bar and used for stacking material onto the material bar or retrieving material from the material bar.

[0006] According to the material storage structure described above, there are two material bars, and two recessed areas are provided on the material yard. The two material bars are respectively arranged in the two recessed areas, and the stacker is located between the two material bars and can move along the length of the material bars.

[0007] According to the material storage structure described above, each of the material bars is provided with a retaining wall on both sides, and the height of the retaining wall is consistent with the depth of the recessed area.

[0008] According to the material storage structure described above, the depth of the recessed area is 1-2m.

[0009] According to the material storage structure described above, the stacker is provided with a cantilever and an angle adjustment unit. The cantilever is used to grab the material, and the angle adjustment unit is installed on the rotating part of the cantilever and is used to adjust the angle of the cantilever so that the cantilever can be located directly above the center line of the material bar.

[0010] According to the material storage structure described above, the angle adjustment unit includes an angle sensor and a hydraulic cylinder. The piston rod of the hydraulic cylinder is connected to the cantilever, and the angle sensor is used to detect the rotation angle of the cantilever.

[0011] According to the material storage structure described above, the air-supported membrane assembly further includes a ring beam, which is embedded at the edge of the material yard and connected to the edge of the air-supported membrane body.

[0012] According to the material storage structure described above, the embedment depth of the ring beam is less than or equal to 1.5m.

[0013] According to the material storage structure described above, multiple pedestrian and vehicle passages are provided on both sides of the air-supported membrane body, and the width of the vehicle passage is greater than the width of the pedestrian passage.

[0014] According to the material storage structure described above, the air membrane body is made of PVDF membrane material.

[0015] This utility model has the following beneficial effects: 1. The air-supported membrane structure can form a self-supporting arched enclosed space by inflating the inside. Compared with building a steel frame, it is simpler to build. Since the air-supported membrane structure has low requirements for the foundation, it can greatly shorten the construction period. Also, since the air-supported membrane is easy to inflate, it does not require interrupting the original work on the material yard. 2. A recessed area is provided in the material yard, which can increase the overall capacity of the enclosed space, thereby increasing the material capacity. The retaining walls on both sides of the material bar can prevent the material on the material bar from tilting due to excessive stacking. This not only increases the material capacity but also prevents it from tilting. 3. The rotation angle of the cantilever can be adjusted by the angle adjustment unit, which can ensure that the cantilever is directly above the center line of the material bar, thus effectively preventing the material from tilting and falling.

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] like Figure 1-2 As shown, a material storage structure includes an air-supported membrane assembly 100, a material strip assembly 200, and a stacking assembly 300, which are used to store materials on a material yard 400.

[0020] Specifically, the air-supported membrane assembly 100 includes an air-supported membrane body 110, which covers the material yard 400 and forms an arched enclosed space through internal inflation. The material strip assembly 200 includes material strips 210 located within the enclosed space and retaining walls 220. A recessed area 410 is provided on the material yard 400, and the material strips 210 are located within the recessed area 410. The retaining walls 220 are located on both sides of the material strips 210. The stacking and retrieving assembly 300 includes a stacker 310 located within the enclosed space. The stacker 310 is movably arranged on one side of the material strips 210 and is used to stack materials onto the material strips 210 or remove materials located on the material strips 210. That is, the material strips 210 are used to place materials. Since they are located within the enclosed space, the air-supported membrane body... 110 provides a shielding function to prevent materials from being directly exposed to the air. The stacker 310 can move along the length of the material bar 210, and can evenly stack the materials on the material bar 210, avoiding concentrated stacking at one point. Since the recessed area 410 is provided on the material yard 400, it expands the enclosed space and increases the overall capacity, that is, higher materials can be stacked on the material bar 210. However, if the material is stacked too high, it will be easy for the material to fall off the side of the material bar 210. Therefore, in this embodiment, a retaining wall 220 is provided on both sides of the material bar 210. The retaining wall 220 can prevent the material from falling off the material bar 210, avoid mixing, improve the capacity, and ensure the stability of the material stacking.

[0021] In this embodiment, since the air-supported membrane body 110 only needs to be inflated, its inflation speed is faster and the operation is simpler compared to the construction of steel structures. Because the air-supported membrane body 110 inflates quickly, it will not take up too much construction time, so that the entire material yard 400 does not need to be shut down, thus avoiding the sharp increase in costs caused by the modification of the material yard 400.

[0022] Furthermore, the air-supported membrane assembly 100 also includes a ring beam 120, which is embedded at the edge of the material yard 400 and connected to the edge of the air-supported membrane body 110. The main function of the ring beam 120 is to fix the air-supported membrane body 110 so that it does not move at will. Since the air-supported membrane body 110 is relatively light compared to the steel structure, its requirements for the foundation are also low, and it does not need to be a very deep foundation. Therefore, in this embodiment, the embedment depth of the ring beam 120 is less than or equal to 1.5m, which is equivalent to the foundation laying depth. The excavation of the foundation requires a long time. Reducing the foundation depth can reduce the construction cycle significantly, thereby achieving the purpose of speeding up the processing and construction.

[0023] Of course, in this embodiment, the ring beam 120 and the retaining wall 220 can be integrally formed, that is, cast at the same time, which can shorten the entire construction cycle.

[0024] Furthermore, multiple pedestrian walkways 111 and vehicle walkways 112 are provided on both sides of the air-supported membrane structure 110. The width of the vehicle walkway 112 is greater than the width of the pedestrian walkway 111. In this embodiment, each side of the air-supported membrane structure 110 is provided with one vehicle walkway 112 and multiple pedestrian walkways 111. The width of the vehicle walkway 112 is typically ≥4 meters and the height is ≥4.5 meters to meet the passage requirements of large vehicles such as trucks and fire trucks. The width of the pedestrian walkway 111 is 0.9–1.5 meters. The spacing between multiple pedestrian walkways 111 on the same side of the air-supported membrane structure 110 is ≥10 meters. It can serve as a temporary evacuation route and can also avoid congestion at a single exit. The vehicle walkway 112 can also serve as an emergency rescue entrance, and its width can accommodate the entry and exit of fire-fighting equipment, thereby improving disaster response capabilities.

[0025] Furthermore, the air-supported membrane body 110 is made of PVDF membrane material, which has the characteristics of high mechanical strength, resistance to chemical solvents and heat stability. It is suitable for use in open-air venues, which can avoid damage caused by exposure to the sun, and can also avoid corrosion by chemicals on steel, thus improving its service life.

[0026] Furthermore, two material bars 210 are provided, and two recessed areas 410 are provided on the material yard 400. The two material bars 210 are respectively arranged in the two recessed areas 410. The stacker 310 is located between the two material bars 210 and can move along the length of the material bars 210. That is, the two material bars 210 can be arranged along the length of the material yard 400, which can make full use of the space within the enclosed area, improve space utilization, and facilitate the stacker 310 to stack and retrieve materials. The action also allows the width of the material bar 210 to be adapted to the stacker 310. If only one material bar 210 is set, the length of the cantilever 311 of the stacker 310 may not be able to reach all positions of the material bar 210. Therefore, there may be a problem of not being able to reach it when picking up or placing materials. However, by setting two material bars 210, the width of a single material bar 210 is narrowed, and the two material bars 210 are symmetrically arranged on both sides of the stacker 310, so that the stacker 310 can reach all areas of both material bars 210 at the same time.

[0027] In order to enable the stacker 310 to move, a guide rail is laid on the material yard 400. The stacker 310 is connected to the guide rail via rollers. It is mainly driven by electricity, and a diesel generator can be installed on the stacker 310 to ensure continuous operation in extreme weather conditions. It supports a straight reciprocating stacking path, and its maximum moving speed is 20m / min, ensuring the rapid stacking and retrieval of materials.

[0028] Furthermore, each material bar 210 is equipped with a retaining wall 220 on both sides, which can fully support the material and prevent the material on the two material bars 210 from falling. When the material yard 400 is not deepened, the height space for stacking materials on the material bar 210 is limited, so it is not necessary to set the retaining wall 220 on both sides of the material bar 210. When a recessed area 410 is set in the material yard 400, the height of the material bar 210 decreases accordingly, and the height that can be used to stack materials on the material bar 210 increases. The increased height range is the depth of the recessed area 410. Therefore, it is only necessary to set the height of the retaining wall 220 to be consistent with the depth of the recessed area 410, which can prevent the material from falling. This can prevent the material from falling, avoid the retaining wall 220 being too high and obstructing the stacker 310 from picking up and placing materials, and reduce costs by avoiding the cost increase caused by the high retaining wall 220.

[0029] Furthermore, the depth of the recessed area 410 is between 1 and 2 meters. This depth ensures the strength of the bottom of the recessed area 410, prevents it from collapsing when it encounters a wet layer, and also makes it easy for the stacker 310 to reach it.

[0030] In this embodiment, since the ring beam 120 needs to be arranged along the edge of the material yard 400, it will occupy 3-5 meters of the original site width, which will narrow the effective width of the material strip 210. Moreover, the distribution of the basic structure is not necessarily uniform. The uneven distribution will cause the narrowing degree on both sides of the material strip 210 to be different, thus forming an irregular material strip 210. If the stacker 310 stacks materials along a straight line, it will cause the material to be unevenly distributed on the material strip 210 and more likely to fall off.

[0031] Furthermore, to address the aforementioned issues, the stacker 310 is equipped with a cantilever 311 and an angle adjustment unit. The cantilever 311 is used to grab materials, and the angle adjustment unit is installed on the rotating part of the cantilever 311 to adjust the angle of the cantilever 311 so that the cantilever 311 can be positioned directly above the center line of the material bar 210. Of course, if the stacker 310 is manned, the operator can visually observe whether the cantilever 311 is positioned at the exact center of the material bar 210. If it is positioned at the exact center of the material bar 210, the operator can control the cantilever 311 to perform the stacking operation. If the cantilever 311 is positioned to one side of the material bar 210, the operator can control the angle adjustment unit to adjust the angle of the cantilever 311, thereby adjusting the position of the cantilever 311 to be positioned directly above the center line of the material bar 210, ensuring the stability of the material stacking.

[0032] Of course, the stacker 310 can also be unmanned. It can adjust the angle of the cantilever 311 by installing a camera on the top of the stacker 310, using the camera to determine the center line of the material bar 210, and automatically controlling the angle adjustment unit.

[0033] Furthermore, the angle adjustment unit includes an angle sensor and a hydraulic cylinder. The piston rod of the hydraulic cylinder is connected to the cantilever 311. The angle sensor is used to detect the rotation angle of the cantilever 311 and whether the cantilever 311 has rotated to the correct position. The hydraulic cylinder is used to perform the driving action on the cantilever 311 and provide power to drive the cantilever 311 to rotate.

[0034] In this embodiment, a material storage structure is disclosed, including an air-film assembly 100, a material strip assembly 200, and a stacking assembly 300. The air-film assembly 100 includes an air-film body 110, which covers the material yard 400 and forms an arched closed space by internal inflation. The material strip assembly 200 includes material strips 210 located within the closed space and retaining walls 220. The material yard 400 has a recessed area 410, with material strips 210 located within the recessed area 410. The retaining walls 220 are located on both sides of the material strips 210. Component 300 includes a stacker 310 located in an enclosed space. The stacker 310 is movably disposed on one side of the material bar 210 and is used to stack materials onto the material bar 210 or remove materials located on the material bar 210. A recessed area 410 is provided in the material yard 400, which can increase the overall capacity of the enclosed space, thereby increasing the material capacity. Furthermore, the retaining walls 220 on both sides of the material bar 210 can prevent the material on the material bar 210 from tilting due to excessive stacking, thus increasing the material capacity and preventing tilting.
