Description

Technical Field

[0001] This invention belongs to the field of industrial building technology, and relates to building energy conservation. It relates to a factory mezzanine structure system that integrates ramp transportation, space reuse and fire protection coordination. Specifically, it relates to a multi-functional integrated mezzanine structure with double-level factory ramps and its usage method. Background Technology

[0002] In the practice of improving the asset value and land use efficiency of industrial plants (especially those with two or more floors), the "double ground floor" design (achieved through the addition of ramps) has become an effective strategy. To maximize the land use efficiency and asset value of two-story and above plants ("double ground floor" design), the core strategy lies in deeply exploring the often-overlooked "negative space" beneath the ramps. Traditional factory ramps only meet vehicle passage requirements, resulting in insufficient utilization of the space beneath them. In existing technologies: 1. Factory offices / warehousing require production space; 2. Independent expansion of the mezzanine requires additional structural columns, which is very expensive; 3. The ramp and the factory fire protection system are not linked in the design (GB50016-2014). Summary of the Invention

[0003] The purpose of this invention is to overcome the defects in the existing technology and provide a multi-functional integrated mezzanine structure with double-level factory ramps, which solves four major pain points: wasted ramp space, mixed factory functions, high renovation costs, and fragmented fire protection zones.

[0004] To achieve the above objectives, the technical solution of the present invention is to design a multi-functional integrated mezzanine structure with a double-level factory ramp, wherein the mezzanine structure is located below the ramp; the mezzanine structure is divided into office units and storage units; a truck cleaning unit is also provided below the ramp on one side of the mezzanine structure; the truck cleaning unit and the storage unit are spaced apart to avoid the entry of trucks affecting the immediate storage, distribution or self-service retrieval of high-frequency materials.

[0005] By placing the storage and retrieval functions of the storage unit on the side of the storage unit away from the office unit, the process of storing and retrieving materials no longer involves the office unit, minimizing the impact of the storage process on the office. This inevitably requires a certain amount of space for personnel to enter and exit to complete the immediate storage, distribution or self-service retrieval of high-frequency materials.

[0006] The mezzanine structure consists of a cantilevered mezzanine below the ramp, the original structural columns of the ramp, the outer enclosure structure, and the base plate. The mezzanine and the ramp are fixedly connected by a two-way steel truss, and the connection between the two-way steel truss and the original structural columns of the ramp is made using M24 chemical anchors.

[0007] By carefully adding a multi-functional integrated mezzanine at a suitable location below the ramp where the structure is structurally safe and clearance is permissible, this idle area can be effectively transformed into high-value usable space. This represents the intensive use of land resources, significantly increasing the economic output and functionality per unit of land.

[0008] An evacuation staircase is provided within the mezzanine structure. The evacuation staircase is a spiral staircase with a step height of ≤175mm. Emergency lighting and fluorescent signs are installed within the mezzanine structure and are located on the inner wall of the outer envelope.

[0009] The mezzanine structure is equipped with fire doors with a width of ≥1.5m, and the walls where the fire doors are located are firewalls with a 3-hour fire resistance rating. The floor slabs in the mezzanine structure are made of detachable steel truss aluminum formwork floor decks. The standard module size of the detachable steel truss aluminum formwork floor decks is 1200×400mm, the aluminum plate thickness is 4.0mm, the concrete pouring thickness is 120mm, the strength grade is C30, and it is reinforced with double-layer bidirectional steel mesh.

[0010] The storage unit is equipped with an intelligent modular service warehouse; the truck cleaning unit is equipped with an automated truck cleaning station; the modular service warehouse is a three-dimensional racking system; the automated truck cleaning station consists of a truck sensing device and an intelligent folding cleaning mechanism in the mezzanine; the intelligent folding cleaning mechanism integrates blowing, sweeping, and vacuuming functions. A method for using a multi-functional integrated mezzanine structure with a double-level factory ramp: office supplies, production materials, and small tools can be stored in or delivered to the automated racking system or retrieved from the automated racking system in real time; after the truck finishes unloading, it drives into the mezzanine structure, and after being identified by the sensing device, the intelligent folding cleaning mechanism inside the mezzanine structure automatically unfolds to perform a fast and efficient cleaning operation on the surface of the truck. This mezzanine design is far more than just space filling; it integrates two core functional modules: an intelligent modular service warehouse and an automated truck cleaning station. The modular service warehouse can be flexibly configured with a three-dimensional shelving system, providing surrounding factories with immediate storage, distribution, or self-service retrieval of frequently used materials (office supplies, production materials, small tools, etc.), transforming it into an "in-plant convenience store" and significantly shortening material acquisition paths while optimizing internal logistics. Simultaneously, an automated cleaning station is cleverly positioned below the top of the ramp: when a truck, having finished unloading, enters via sensors, the intelligent folding cleaning mechanism (integrating blowing, sweeping, and vacuuming functions) within the mezzanine automatically unfolds, performing a rapid and efficient cleaning operation on the truck's surface. This not only significantly improves the cleanliness of the factory environment, meeting high management standards, but also reduces the risk of contaminants being brought into clean areas, ensuring production quality.

[0011] A mezzanine is added at a suitable location below the ramp. Functionally, it can provide office space or material storage space for surrounding factories, avoiding encroachment on factory space for office and storage purposes and ensuring the regularity of the factory's own space. Structurally, it can add ties to further enhance structural stability. In terms of cost, by utilizing the existing structural columns of the ramp, only the external enclosure structure and the base slab need to be added, which can reduce the unit cost. In terms of evacuation, the ramp mezzanine is combined with a surrounding factory to form a fire compartment, using the factory's staircase as an evacuation exit, and adding another evacuation staircase, thus meeting the two evacuation exits required by fire protection regulations.

[0012] The specific structural innovations are as follows: Utilizing the original structural columns for load-bearing, a two-way steel truss was added to connect the mezzanine and the ramp. Lateral force resisting system: X-shaped damping tie rod, yield strength ≥235MPa; Node connection design: A new type of node using flat steel tube concrete columns is adopted to improve the compressive and shear resistance of the columns, increasing the shear bearing capacity of the nodes by 40%; M24 chemical anchors (grade 8.8) are used to connect the steel beams to the original structural columns (each planar truss can be regarded as a "lattice beam"; the upper chord bears the compressive force, the lower chord bears the tensile force, and the web members bear the shear force. They work together, and their overall effect is equivalent to a very tall and very efficient beam). The pre-embedded depth is ≥20d (d is the bolt diameter). The diagonal steel supports use ∅120×6mm steel pipes, forming a 45° angle with the main structure, with a spacing of ≤4.5m. The floor slab system uses detachable steel truss aluminum formwork floor decks with standard module dimensions of 1200×400mm, aluminum plate thickness of 4.0mm, concrete pouring thickness of 120mm, strength grade C30, and internal double-layer bidirectional steel mesh.

[0013] Furthermore, this design incorporates fire protection coordination: It shares a fire compartment with adjacent factory buildings, with fire doors ≥1.5m wide, separated by a 3-hour fire-resistant fire wall, and no doors or windows are allowed within 2m on either side of the fire wall, and an automatic sprinkler system is required.

[0014] Evacuation system: Use the existing factory staircase + add a new spiral staircase with a step height ≤175mm; add a new outdoor steel staircase with a clear width ≥1.1m and a step height ≤175mm, and install emergency lighting and fluorescent signs.

[0015] The mezzanine structure is divided into office units and storage units; a truck cleaning unit is located below the ramp on one side of the mezzanine structure; the storage unit is a three-dimensional racking system, the truck cleaning unit is located on the side adjacent to the three-dimensional racking system, and the office unit is located on the other side adjacent to the three-dimensional racking system; the truck cleaning unit is an automated truck cleaning station. A temporary shelf is installed within the mezzanine, located at the truck cleaning unit. The temporary shelf includes several air column bags and several spaced vertical rubber strips fixedly connected to the air column bags. The length of the air column bags is horizontal. Several temporary storage positions are set on the temporary shelf, each with an elastic airbag clamp. At each temporary storage position, a cylinder is fixedly connected to the temporary shelf between two adjacent air column bags located at the elastic airbag clamp. The protruding end of the cylinder's piston rod faces the elastic airbag clamp, and the cylinder is signal-connected to a controller located outside the temporary shelf. A row of air column bags arranged side-by-side constitutes the main body of the temporary shelf. The length of the main body... A vertical rubber strip is fixedly connected to each of the two edges of the ramp. A baffle is hinged to the vertical rubber strip closer to the automated racking system, and several tension springs arranged from top to bottom are fixedly connected to the vertical rubber strip farther away from the automated racking system. The baffle is hinged to the vertical rubber strip by hinges. A torsion spring is installed on the hinge shaft, and a limiting protrusion is provided on the hinge. One end of the tension spring is fixedly connected to the vertical rubber strip, and the other end is fixedly connected to the original structural column or external enclosure structure of the ramp. A protruding slider is provided on the original structural column or external enclosure structure of the ramp, and all vertical rubber strips on the temporary rack are provided with grooves that match the sliders. The elastic airbag clamp is used to attach pre-made independent elastic airbags to preset positions on the air column bag. Specifically, this is done by using high-strength industrial adhesives or by subjecting the air column bag to localized heat pressing. Alternatively, the elastic airbag clamp can be used to bind the independent elastic airbags to the air column bag using adjustable elastic straps, buckles, or other physical methods. This allows the elastic airbags to be tightly pressed against the air column bag. In this design, such elastic airbags are referred to as elastic airbag clamps, which can clamp the materials to be stored between the elastic airbags and the air column bag.

[0016] The temporary shelving is located near the edge of the truck cleaning unit to prevent it from being hit when the truck enters; the length of the temporary shelving is aligned with the length of the truck cleaning unit. Because a baffle is hinged to the vertical rubber strip, and a torsion spring is installed on the hinge axis of the hinge, the baffle is in an "open" state when no force is applied (i.e., the baffle is perpendicular to the main body of the temporary shelving). Therefore, when the truck enters, it moves the temporary shelving, but when the truck exits, the temporary shelving and its baffle are not moved by the truck. Furthermore, due to the tension spring, the temporary shelving slides back to its original position, allowing it to move with the truck when it enters and return to its original position without leaving the truck cleaning unit when it exits.

[0017] If immediate storage is required, materials are first placed on temporary shelves (specifically, materials are placed between elastic airbag clamps and air column bags, where they are tightly clamped by the elasticity of the airbag clamps). When the truck enters, it moves the temporary shelves, causing the materials to move closer to the automated storage and retrieval system. The truck stops when it reaches the truck cleaning unit (even without the temporary shelves, the truck would normally stop receiving blowing, cleaning, and vacuuming upon reaching the cleaning unit). Upon stopping (the controller first sends a signal to activate the cylinders to push the elastic airbag clamps), the robotic arm is operated to retrieve the materials from the temporary shelves and place them into the automated storage and retrieval system for blowing, cleaning, and vacuuming. After the blowing, cleaning, and vacuuming are completed, the truck drives out. The final placement of the materials is achieved manually by operating the robotic arm.

[0018] If self-service material retrieval is required, the truck will stop after reaching the truck cleaning unit. During the stop, blowing, sweeping, and vacuuming will be performed. After the blowing, sweeping, and vacuuming are completed, the materials in the automated racking system will be retrieved by operating the robotic arm and placed on the temporary rack. Then, when the truck drives away, the materials can be retrieved manually from the side of the truck.

[0019] The advantages and beneficial effects of this invention are as follows: A mezzanine is added at a suitable location below the ramp. Functionally, it can provide office space or material storage space for surrounding factories, avoiding encroachment on factory space for office and storage purposes and ensuring the regularity of the factory's own space. Structurally, additional tie rods can be added to further enhance structural stability. In terms of cost, utilizing the existing structural columns of the ramp, only the external enclosure structure and base slab need to be added, reducing the unit cost. Regarding evacuation, the ramp mezzanine is combined with a surrounding factory building to form a fire compartment, using the factory building's staircase as an evacuation exit, and adding another evacuation staircase, thus achieving two evacuation exits as required by fire safety regulations.

[0020] By utilizing the movement of trucks, high-frequency materials can be stored, delivered, or retrieved instantly regardless of whether trucks are present. This allows the truck cleaning unit to be positioned close to one side of the storage unit, further maximizing the space beneath the ramp. This avoids the situation described in Example 1, where the truck cleaning unit must maintain a certain distance from the storage unit to prevent truck traffic from interfering with the instant storage, delivery, or self-service retrieval of high-frequency materials (or, as in existing technology, where materials must be retrieved from the office unit to the storage unit, requiring passage through the office unit and significantly impacting office staff due to the high frequency of material handling). This arrangement indirectly increases the space available for the office or storage unit beneath the ramp, and the material handling activities occur outside the mezzanine (or significantly away from the office unit). This aligns perfectly with improving the asset value and land use efficiency of industrial plants, making it a highly effective and ingenious strategy that significantly increases space utilization and greatly reduces the impact of material handling on office staff.

[0023] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0024] Example 1: As Figures 1 to 4 As shown (for ease of illustration), Figure 2 Trucks are not shown. Figure 3 The office unit, storage unit, and truck cleaning unit are not shown; the truck cleaning unit is indicated by dashed lines because it is not actually isolated by a panel. In practice, a baffle fixed to the ground can be used to limit the parking position of the truck to ensure the distance between the truck cleaning unit and the storage unit. This invention is a multi-functional integrated mezzanine structure with a double-level factory ramp. A multi-functional integrated mezzanine is set up at a location below the ramp where the structure is safe and the clearance is permissible, serving as office space or material storage space. The mezzanine consists of the original structural columns of the ramp, the external enclosure structure, and the base plate. The mezzanine structure is located below ramp 3; the mezzanine structure is divided into office unit 1 and storage unit 2; a truck cleaning unit 4 is also located on one side of the mezzanine structure below the ramp; the truck cleaning unit and storage unit 2 are spaced apart to avoid trucks entering and affecting the immediate storage, distribution or self-service retrieval of frequently used materials. An evacuation staircase 6 is provided inside the mezzanine structure.

[0025] The mezzanine integrates an intelligent modular service warehouse and an automated truck cleaning station; the modular service warehouse can be flexibly configured with a three-dimensional racking system; the automated truck cleaning station is located below the top of the ramp; the automated truck cleaning station consists of a truck sensing device and an intelligent folding cleaning mechanism in the mezzanine; the intelligent folding cleaning mechanism integrates blowing, sweeping, and vacuuming functions. Instructions for use: Store office supplies, production materials, and small tools into the automated storage and retrieval system immediately, or deliver them into or out of the automated storage and retrieval system, or retrieve them from the automated storage and retrieval system by yourself; after the truck finishes unloading, it drives into the mezzanine. Once the sensor detects the truck, the intelligent folding cleaning mechanism in the mezzanine automatically unfolds to perform a fast and efficient cleaning operation on the surface of the truck. (1) Spatial Reconstruction System A cantilevered mezzanine is constructed beneath the ramp, with a depth ≤ 60% of the ramp's horizontal projection. The mezzanine is divided into office units, storage units, and truck cleaning units, with a floor height of ≥2.4m. The truck cleaning units and storage units are spaced apart to prevent the entry of trucks from affecting the immediate storage, delivery, or self-service retrieval of high-frequency materials.

[0026] (2) Structural innovation Utilizing the original structural columns for load-bearing, a two-way steel truss was added to connect the mezzanine and the ramp. Lateral force resisting system: X-shaped damping tie rod, yield strength ≥235MPa; Node connection design: A new type of node using flat steel pipe concrete columns is adopted to improve the compressive and shear resistance of the column, increasing the shear bearing capacity of the node by 40%; M24 chemical anchors (grade 8.8) are used to connect the steel beams to the original structural columns, with a pre-embedded depth ≥20d (d is the bolt diameter); the diagonal steel supports use ∅120×6mm steel pipes, forming a 45° angle with the main structure, with a spacing ≤4.5m; The floor slab system uses detachable steel truss aluminum formwork floor decks with standard module dimensions of 1200×400mm, aluminum plate thickness of 4.0mm, concrete pouring thickness of 120mm, strength grade C30, and internal double-layer bidirectional steel mesh.

[0027] (3) Fire protection collaborative design It shares a fire compartment with adjacent factory buildings, with fire doors ≥1.5m wide, separated by a 3-hour fire-resistant fire wall, and no doors or windows are allowed within 2m on either side of the fire wall, and an automatic sprinkler system is required.

[0028] Evacuation system: Use the existing factory staircase + add a new spiral staircase with a step height ≤175mm; add a new outdoor steel staircase with a clear width ≥1.1m and a step height ≤175mm, and install emergency lighting and fluorescent signs.

[0029] Example 2: The difference from Example 1 is that, as shown in Example 2... Figures 5 to 9 As shown (for ease of illustration), Figure 5 (Examples of tension springs, hinges, slides, and baffles are not shown). The mezzanine is divided into office unit 1 and storage unit 2. Below the ramp, there is also a truck cleaning unit 4 located on one side of the mezzanine structure. The storage unit is a three-dimensional racking system. The truck cleaning unit 4 is located on the side adjacent to the three-dimensional racking system, and the office unit 1 is located on the other side adjacent to the three-dimensional racking system. The truck cleaning unit is an automated truck cleaning station. A temporary shelf is installed within the mezzanine at the location of the truck cleaning unit 4. The temporary shelf includes several air column bags 7 and several spaced vertical rubber strips 8 fixedly connected to the air column bags. The length of the air column bags is horizontal. Several temporary storage positions are set on the temporary shelf, and each temporary storage position is equipped with an elastic airbag clamp 9. At each temporary storage position, a cylinder 10 is fixedly connected to the temporary shelf between two adjacent air column bags located at the elastic airbag clamp. The protruding end of the cylinder's piston rod faces the elastic airbag clamp, and the cylinder is signal-connected to a controller located outside the temporary shelf. The air column bags are arranged side-by-side in a row, forming the main body of the temporary shelf. The length of the main body is two... A vertical rubber strip is fixedly connected to each side edge. A baffle 11 is hinged to the vertical rubber strip closer to the automated racking system, and several tension springs 12 arranged from top to bottom are fixedly connected to the vertical rubber strip farther away from the automated racking system. The baffle is hinged to the vertical rubber strip via a hinge 13. A torsion spring is provided on the hinge shaft, and a limiting protrusion is provided on the hinge. One end of the tension spring 12 is fixedly connected to the vertical rubber strip 8, and the other end is fixedly connected to the original structural column of the ramp or the outer enclosure structure. A protruding slider is provided on the original structural column of the ramp or the outer enclosure structure, and all vertical rubber strips on the temporary rack are provided with a sliding groove 14 that matches the slider. By utilizing the movement of trucks, high-frequency materials can be stored, delivered, or retrieved instantly regardless of whether trucks are present. This allows the truck cleaning unit to be positioned close to one side of the storage unit, further maximizing the space beneath the ramp. This avoids the situation described in Example 1, where the truck cleaning unit must maintain a certain distance from the storage unit to prevent truck traffic from interfering with the instant storage, delivery, or self-service retrieval of high-frequency materials (or, as in existing technology, where materials must be retrieved from the office unit to the storage unit, requiring passage through the office unit and significantly impacting office staff due to the high frequency of material handling). This arrangement indirectly increases the space available for the office or storage unit beneath the ramp, and the material handling activities occur outside the mezzanine (or significantly away from the office unit). This aligns perfectly with improving the asset value and land use efficiency of industrial plants, making it a highly effective and ingenious strategy that significantly increases space utilization and greatly reduces the impact of material handling on office staff.

[0030] The elastic airbag clamp is used to attach pre-made independent elastic airbags to preset positions on the air column bag. Specifically, this is done by using high-strength industrial adhesives or by subjecting the air column bag to localized heat pressing. Alternatively, the elastic airbag clamp can be used to bind the independent elastic airbags to the air column bag using adjustable elastic straps, buckles, or other physical methods. This allows the elastic airbags to be tightly pressed against the air column bag. In this design, such elastic airbags are referred to as elastic airbag clamps, which can clamp the materials to be stored between the elastic airbags and the air column bag.

[0031] The temporary shelving is located near the edge of the truck cleaning unit to prevent it from being hit when the truck enters; the length of the temporary shelving is aligned with the length of the truck cleaning unit. Because a baffle is hinged to the vertical rubber strip, and a torsion spring is installed on the hinge axis of the hinge, the baffle is in an "open" state when no force is applied (i.e., the baffle is perpendicular to the main body of the temporary shelving). Therefore, when the truck enters, it moves the temporary shelving, but when the truck exits, the temporary shelving and its baffle are not moved by the truck. Furthermore, due to the tension spring, the temporary shelving slides back to its original position, allowing it to move with the truck when it enters and return to its original position without leaving the truck cleaning unit when it exits.

[0032] If immediate storage is required, materials are first placed on temporary shelves (specifically, materials are placed between elastic airbag clamps and air column bags, where they are tightly clamped by the elasticity of the airbag clamps). When the truck enters, it moves the temporary shelves, causing the materials to move closer to the automated storage and retrieval system. The truck stops when it reaches the truck cleaning unit (even without the temporary shelves, the truck would normally stop receiving blowing, cleaning, and vacuuming upon reaching the cleaning unit). Upon stopping (the controller first sends a signal to activate the cylinders to push the elastic airbag clamps), the robotic arm is operated to retrieve the materials from the temporary shelves and place them into the automated storage and retrieval system for blowing, cleaning, and vacuuming. After the blowing, cleaning, and vacuuming are completed, the truck drives out. The final placement of the materials is achieved manually by operating the robotic arm.

[0033] If self-service material retrieval is required, the truck will stop after reaching the truck cleaning unit. During the stop, blowing, sweeping, and vacuuming will be performed. After the blowing, sweeping, and vacuuming are completed, the materials in the automated racking system will be retrieved by operating the robotic arm and placed on the temporary rack. Then, when the truck drives away, the materials can be retrieved manually from the side of the truck.

[0034] Example 3: The difference from Example 1 is that, as shown in Example 3... Figures 10 to 12As shown, the mezzanine structure is divided into office unit 1 and storage unit 2; below the ramp 3, there is also a truck cleaning unit 4 located on one side of the mezzanine structure; the storage unit is a three-dimensional racking system, with the truck cleaning unit on one side of the three-dimensional racking system and the office unit on the other side adjacent to the three-dimensional racking system; the truck cleaning unit is an automated truck cleaning station. Each storage location in the automated racking system is connected to a material handling channel 15 made of a PTFE-lined flexible hose. A cover plate 16 is installed at each storage location within the automated racking system. The shape and size of the cover plate are adapted to the cross-section of the material handling channel. The center of the cover plate, away from the automated racking system, is fixedly connected to a connecting rope. On the same side of the cover plate, three roller frames arranged in a circular array are also installed, with rollers 17 rotating on them. The roller surfaces are flush with the side of the cover plate. A hook 18 is fixedly installed on the side of the cover plate closest to the automated racking system. Plastic bags for placing materials are hung above. [When storing materials, the materials are placed directly into the plastic bags, and then the cover is placed directly into the retrieval channel, away from the automated storage and retrieval system. Due to the roller frame and the PTFE-lined flexible hose used in the retrieval channel, the cover can smoothly slide into the retrieval channel, near the automated storage and retrieval system, and finally fall into the storage location. When materials need to be retrieved, the connecting rope is pulled, and the cover moves upward along the retrieval channel until it reaches the retrieval channel away from the automated storage and retrieval system. The plastic bag is then opened to retrieve the materials. This setup places the immediate storage and self-service retrieval of materials above the truck entry and exit area, enabling high-frequency immediate storage, distribution, or self-service retrieval of materials during the process of trucks entering the truck cleaning unit, during the process of blowing, cleaning, and vacuuming when they stop, and during the process of trucks leaving the truck cleaning unit after blowing, cleaning, and vacuuming.] The material handling aisle is located at the truck cleaning unit and avoids the space where trucks 5 enter and exit, primarily situated above this space. Located at or below the truck's roof height, one end of the aisle connects to the storage location of the automated racking system, while the other end is located within the truck cleaning unit space above the truck's roof height. The lower middle section of this aisle is supported by inclined support plates 19 fixedly connected to the existing structural columns of the ramp and / or the external enclosure structure. (To better support the aisle and facilitate the sliding of the cover plate and materials, the support plate has an arc-shaped lower section and an inclined upper section forming an angle with the main body of the support plate; the main body of the support plate is another inclined plate.) However, it occupies a little space, so the truck cleaning unit on one side of the automated racking system still needs to be kept a short distance from the racking system. This distance is mainly to accommodate the space for tilting or bending material loading and unloading, as well as the placement of support plates. This arrangement only occupies a small amount of space, and only requires a small distance between the truck cleaning unit and the automated racking system. The distance is small, so it can still avoid the situation in Embodiment 1 where the truck cleaning unit must have a certain distance from the storage unit to prevent the entry of trucks from affecting the immediate storage, distribution, or self-service retrieval of high-frequency materials. Embodiment 1 requires a larger distance to allow people to enter that space to pick up and put down materials.

[0035] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
