Technical Field

[0001] This utility model relates to the field of transfer devices, and in particular to a multi-functional warehouse trailer. Background Technology

[0002] In modern logistics and warehousing management, trailers are an important means of transportation, widely used for short-distance handling and storage of goods. Traditional warehouse trailers are typically designed with a fixed structure and limited functionality, making it difficult to adapt to the needs of goods of different sizes, shapes, and weights. With the rapid development of the logistics industry and the increasing complexity of warehousing environments, higher demands are placed on the flexibility, versatility, and scalability of trailers.

[0003] The existing warehouse trailers have the following problems:

[0004] 1. Limited functionality: Traditional trailers are usually only used for handling specific types of goods and cannot meet diverse warehousing needs.

[0005] 2. Fixed interface: The interface design of the trailer is relatively fixed, making it difficult to quickly connect with other equipment or trailers, resulting in low handling efficiency.

[0006] 3. Inconvenient operation: Some trailers require complex operations for connection or disassembly, increasing the labor intensity and time cost for workers. Currently, common warehouse trailers are mainly single-function, and different types or specifications of trailers are needed for different kinds of products. Utility Model Content

[0007] To address the issues of limited functionality and fixed interfaces in existing warehouse trailers, this utility model provides a multi-functional warehouse trailer.

[0008] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0009] A multi-functional warehouse trailer includes a flatbed trailer with several sets of fixing holes for mounting and disassembling a mounting frame. Selecting different sets of fixing holes allows the mounting frame to be fixed in different positions. Shaft-type fixing components and box-type fixing components are detachably mounted on the mounting frame. By providing fixing holes on the flatbed trailer, mounting the mounting frame in these holes, and then mounting the shaft-type and box-type fixing components on the mounting frame, this multi-functional warehouse trailer can transport both shaft-type and box-type items, breaking the limitations of traditional single-function transfer equipment. The ability to fix the mounting frame in different positions by selecting different sets of fixing holes greatly expands the applicability of the multi-functional warehouse trailer, meeting the transportation needs of different types of goods and improving logistics efficiency. The mounting brackets are detachable and can be installed on the flatbed trailer via mounting holes. Users can select the number and location of the mounting brackets according to the type of goods being transported. They can then choose to install shaft-type, box-type, or both types of fixing components on the mounting brackets. This also allows for the transport of other types of goods using only the flatbed trailer, easily handling different transportation scenarios and avoiding the hassle of changing different transfer equipment due to changes in cargo type. A single multi-functional warehouse trailer can replace multiple single-function transfer devices, reducing the number of equipment purchased and the procurement cost. Simultaneously, the equipment's versatility reduces maintenance and management costs, eliminating the need for multiple maintenance plans for different types of transfer equipment, thus reducing equipment management difficulty and maintenance costs. The detachable installation method simplifies the installation and removal of shaft-type and box-type fixing components, requiring no complex tools or specialized skills, saving installation and replacement time, improving work efficiency, reducing the labor intensity of operators, and enhancing the overall efficiency of logistics transfer.

[0010] Preferably, the flatbed trailer includes a chassis; wheels are mounted on the bottom of the chassis; a drawbar is mounted on the front end of the chassis; and several sets of fixing holes are provided on the chassis. The wheels on the bottom of the chassis reduce friction during movement, requiring only a small traction force to move the flatbed. The drawbar at the front end of the chassis facilitates connection to power equipment such as tractors and forklifts, enabling easy long-distance transportation with the aid of an external power source. The fixing holes on the chassis provide mounting bases for axle-type fixing components, box-type fixing components, and mounting brackets, allowing for flexible adjustment of the installation position and combination of fixing components according to different cargo shapes, sizes, and weights. This improves the flatbed trailer's adaptability to different cargoes and meets diverse transportation needs.

[0011] Preferably, several ratchet tensioners are spaced apart along the length of the chassis on both sides. During transportation, ratchet tensioners at different positions can be used flexibly according to the size and shape of the goods to tighten ropes or straps, thus securing the goods firmly to the flatbed and preventing displacement, shaking, or slippage during transportation. This ensures the safety and stability of the goods transportation, and is especially suitable for transporting large, irregular, or heavy goods.

[0012] Preferably, each set of fixing holes includes several pin holes arranged in a matrix; the fixing holes are arranged along the length of the chassis; each pin hole is a stepped hole; a pin is installed in the pin hole; the pin passes through the mounting bracket and is then placed in the pin hole; a receiving box is provided on the bottom rear of the chassis for storing the pin. The matrix arrangement of the pin holes effectively prevents swaying and offset in the width direction when the mounting bracket is installed. Compared with single-point fixing, this greatly enhances the stability and reliability of the fixing, ensuring that the fixing components will not loosen due to vehicle vibration or other factors during transportation, thus guaranteeing the safety of cargo transportation. This regular and uniform arrangement of fixing holes facilitates standardized operations during flatbed trailer production, improving production efficiency and reducing production costs. Simultaneously, it also facilitates the standardized design and production of axle fixing components, box fixing components, and mounting brackets, further enhancing the versatility and interchangeability of the entire multi-functional warehouse trailer, and facilitating later maintenance and parts replacement. A storage box is provided on the bottom of the rear of the chassis to store the pins, which facilitates the storage and management of the pins, prevents the pins from being lost, and allows the pins to be quickly found and used when it is necessary to install and fix components, thereby improving work efficiency.

[0013] Preferably, the mounting frame includes several crossbeams; mounting holes are formed on the crossbeams to accommodate pin holes; two longitudinal beams are fixedly mounted on the crossbeams; the two longitudinal beams are spaced apart. The fixed mounting of two spaced longitudinal beams on the crossbeams forms a stable frame structure, increasing the overall strength and rigidity of the mounting frame. This allows it to withstand greater cargo weight and various stresses during transportation, preventing deformation and damage, extending the service life of the mounting frame, reducing equipment replacement costs, and facilitating the installation of shaft-type and box-type fixing components. Users can install different numbers of shaft-type and box-type fixing components on the mounting frame according to the characteristics of the cargo, further expanding the functionality and applicability of this multi-functional warehouse trailer.

[0014] Preferably, stiffening ribs are fixedly installed at the connection between the longitudinal beams and the transverse beams. This increases the connection strength between the longitudinal beams and the transverse beams, improves the overall structural strength and rigidity of the mounting frame, enabling it to withstand greater cargo weight and various stresses generated during transportation, effectively preventing deformation and damage to the mounting frame, extending its service life, and reducing equipment replacement costs.

[0015] Preferably, several through holes are provided on the side wall of the longitudinal beam, and copper sleeves are fixedly installed in the through holes. Because the copper sleeves reduce wear between components, the frequency of equipment failures due to wear is reduced, decreasing the number of equipment repairs and the need for replacement parts, thereby lowering maintenance costs and improving the equipment's uptime and operating efficiency.

[0016] Preferably, the shaft fixing assembly includes a bracket; a first U-shaped base is fixedly installed at both corners of the bottom surface of the bracket; an arc-shaped plate is fixedly installed on the top surface of the bracket; and a first through hole is formed on the first U-shaped base to fit a copper sleeve. The first U-shaped base at both corners of the bottom surface of the bracket of the shaft fixing assembly can precisely mate with the copper sleeve on the mounting frame. It is fixed by connecting parts such as pins passing through the first through hole of the base and the copper sleeve, ensuring stable installation and accurate positioning, preventing displacement of the shaft fixing assembly during transportation, and providing a reliable fixing foundation for the shaft. The arc-shaped plate fixed on the top surface of the bracket has a shape that closely matches the cylindrical shape of the shaft, allowing it to tightly fit the shaft surface, increasing the contact area, dispersing pressure, and preventing damage to the shaft surface. It also effectively prevents the shaft from rolling or shaking during transportation, improving transportation safety. The first concave base, in conjunction with the copper sleeve, has a first through hole. This allows the shaft fixing component to be installed simply by aligning the connector with the first through hole, eliminating the need for complex positioning and calibration processes. The installation process is simple and quick, greatly reducing installation time, improving work efficiency, and facilitating the rapid replacement or adjustment of the shaft fixing component's position in different scenarios.

[0017] Preferably, the box-fixing assembly includes a box body; a second U-shaped base is fixedly disposed on the bottom surface of the box body; a second through hole is formed on the second U-shaped base to fit a copper sleeve. The box body of the box-fixing assembly, designed with box feet, allows the box feet to be placed inside the box body, effectively limiting the horizontal displacement of the box body during transportation, preventing the box body from sliding or tipping over on the flatbed truck, providing a stable placement platform for boxed goods, and ensuring transportation safety. This fixing assembly design is suitable for various boxed items of different sizes and shapes. As long as the box feet can be placed inside the box body, effective fixing can be achieved, greatly improving the versatility of the multi-functional warehouse trailer for boxed goods and meeting the transportation needs of different types of boxed goods.

[0018] Preferably, the box body is a shell-like structure with an open top; threaded holes are provided on all the peripheral walls of the box. The open top shell shape allows for the placement of box feet within the box, effectively limiting horizontal displacement during transport and preventing the box from sliding or tipping over on the flatbed truck. This provides a stable platform for boxed goods and ensures safe transport. This design is suitable for various sizes and shapes of boxed items; as long as the box feet can be placed inside the box, effective fixation is achieved, greatly improving the versatility of the multi-functional warehouse trailer for boxed goods and meeting the transport needs of different types of boxed goods. The threaded holes on the peripheral walls of the box allow bolts to be passed through them and secured against the box feet, making operation simple and convenient, further enhancing the fixation effect and ensuring the stability of boxed goods during transport.

[0019] As can be seen from the above technical solution, the advantages of this utility model are as follows: By setting fixing holes on the flatbed trailer and installing mounting brackets on these holes, and then installing shaft-type fixing components and box-type fixing components on the mounting brackets, this multi-functional warehouse trailer can transport both shaft-type and box-type items, breaking the limitation of traditional single-function transfer equipment. Selecting different sets of fixing holes allows the mounting brackets to be fixed in different positions, greatly improving the applicability of the multi-functional warehouse trailer and meeting the transportation needs of different types of goods, thus improving logistics efficiency. The mounting brackets can be detachably installed on the fixing holes on the flatbed trailer. Users can choose the number and position of the mounting brackets according to the actual type of goods being transported, and then choose to install shaft-type fixing components, box-type fixing components, or both simultaneously on the mounting brackets. It also allows the use of only the flatbed trailer to transport other types of goods, easily handling different transportation scenarios and avoiding the hassle of changing different transfer equipment due to changes in the type of goods. One multi-functional warehouse trailer can replace multiple single-function transfer devices, reducing the number of equipment purchased and the procurement cost. Meanwhile, the equipment's versatility reduces maintenance and management costs, eliminating the need for multiple maintenance plans for different types of transfer equipment, thus lowering the difficulty of equipment management and maintenance costs. The detachable installation method simplifies the installation and removal of shaft and box-type fixing components, requiring no complex tools or specialized skills. This saves installation and replacement time, improves work efficiency, reduces the workload of operators, and enhances the overall efficiency of logistics transfer. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0027] like Figure 1 As shown, a multi-functional warehouse trailer includes a flatbed trailer 1. The flatbed trailer 1 is provided with several sets of fixing holes for disassembling and installing a mounting frame 2. Selecting different sets of fixing holes can fix the mounting frame in different positions. Shaft-type fixing components and / or box-type fixing components can be detachably installed on the mounting frame 2.

[0028] By setting fixing holes on the flatbed trailer 1, mounting brackets 2 are installed on these holes, and shaft and box fixing components are installed on the mounting brackets 2. This allows the multi-functional warehouse trailer to transport both shaft-type and box-type items, breaking the limitations of traditional single-function transfer equipment. Different sets of fixing holes allow the mounting brackets 2 to be fixed in different positions, greatly expanding the applicability of the multi-functional warehouse trailer and meeting the transportation needs of different types of goods, thus improving logistics efficiency. The mounting brackets 2 are detachably installed on the fixing holes on the flatbed trailer 1. Users can select the number and position of the mounting brackets 2 according to the actual type of goods being transported, and then choose to install shaft-type, box-type, or both fixing components on the mounting brackets 2. Alternatively, other types of goods can be transported using only the flatbed trailer 1, easily handling different transportation scenarios and avoiding the hassle of changing transfer equipment due to changes in goods type. One multi-functional warehouse trailer can replace multiple single-function transfer devices, reducing the number of equipment purchased and the procurement cost. Meanwhile, the equipment's versatility reduces maintenance and management costs, eliminating the need for multiple maintenance plans for different types of transfer equipment, thus lowering the difficulty of equipment management and maintenance costs. The detachable installation method simplifies the installation and removal of shaft and box-type fixing components, requiring no complex tools or specialized skills. This saves installation and replacement time, improves work efficiency, reduces the workload of operators, and enhances the overall efficiency of logistics transfer.

[0029] like Figure 2 As shown, the flatbed trolley 1 includes a chassis 6; wheels 7 are mounted on the bottom surface of the chassis 6; a tow bar 8 is mounted on the front end of the chassis 6; two sets of fixing holes are provided on the chassis 6. Several ratchet tensioners 5 are spaced apart along the length direction on the left and right sides of the chassis 6. Each set of fixing holes includes six pin holes 17 arranged in a 2×3 matrix; the two sets of fixing holes are arranged along the length direction of the chassis 6; each pin hole 17 is a stepped hole; a pin is installed in the pin hole 17; the pin passes through the mounting bracket 2 and is placed in the pin hole 17; a receiving box 20 is provided on the rear bottom surface of the chassis 6 for storing the pin.

[0030] Wheels 7 are mounted on the bottom of the chassis 6, reducing friction when the flatbed 1 moves, allowing it to be moved with less traction. A drawbar 8 is mounted at the front of the chassis 6, facilitating connection with power equipment such as tractors and forklifts, enabling easy long-distance transportation with the aid of an external power source. Two sets of fixing holes are provided on the chassis 6, providing a mounting base for axle-type fixing components, box-type fixing components, and mounting brackets 2. The installation position and combination of axle-type fixing components and box-type fixing components can be flexibly adjusted according to the shape, size, and weight of the goods, improving the adaptability of the flatbed 1 to different goods and meeting diverse transportation needs. Several ratchet tensioners 5 are spaced along the length of the left and right sides of the chassis 6. During transportation, ratchet tensioners 5 in different positions can be used flexibly according to the size and shape of the goods to tighten ropes or straps, firmly securing the goods to the flatbed 1 and preventing displacement, shaking, or slippage during transportation, ensuring the safety and stability of transportation, especially suitable for large, irregular, or heavy goods. Each set of fixing holes includes pin holes 17 arranged in a 2×3 matrix. When installing the mounting bracket 2, the matrix fixing method effectively prevents swaying and offset in the width direction. Compared with single-point fixing, it greatly enhances the stability and reliability of the fixing, ensuring that the fixing components will not loosen due to vehicle vibration or other factors during transportation, thus guaranteeing the safety of cargo transportation. The regular and uniform setting of the fixing holes facilitates standardized operations during the production of the flatbed trailer 1, improving production efficiency and reducing production costs. At the same time, it also facilitates the standardized design and production of related fixing components and mounting brackets 2, enhancing the versatility and interchangeability of the entire multi-functional warehouse trailer, and facilitating later maintenance and parts replacement. A receiving box 20 is provided on the rear bottom surface of the chassis 6 to store pins, facilitating the storage and management of pins, preventing pin loss, and allowing for quick location and use of pins when installing shaft-type fixing components and box-type fixing components, improving work efficiency.

[0031] like Figure 3 As shown, the mounting bracket 2 includes three crossbeams 11; the distance between two adjacent crossbeams 11 is equal to the distance between two adjacent sets of fixing holes; mounting holes 18 are provided on the crossbeams 11 with mating pin holes 17; two longitudinal beams 9 are fixedly mounted on the three crossbeams 11; the two longitudinal beams 9 are spaced apart. Ribs are fixedly mounted at the connection between the longitudinal beams 9 and the crossbeams 11. Several through holes are provided on the side wall of the longitudinal beams 9, and copper sleeves 10 are fixedly installed in the through holes.

[0032] Mounting holes 18 are provided at both ends of the crossbeams 11. The six mounting holes 18 on the three crossbeams 11, in conjunction with the pin holes 17, allow the mounting frame 2 to precisely mate with the fixing holes on the chassis 6, ensuring the accuracy and stability of the installation and facilitating the quick installation, disassembly, and assembly of the mounting frame. Two spaced longitudinal beams 9 are fixedly installed on the three crossbeams 11, forming a stable frame structure. Stiffening plates are also fixed at the connection points between the longitudinal beams 9 and the crossbeams 11, increasing the overall strength and rigidity of the mounting frame 2. This allows it to withstand greater cargo weight and various stresses during transportation, effectively preventing deformation and damage, extending its service life, and reducing equipment replacement costs. The standardized crossbeam and longitudinal beam structure provides convenient conditions for installing different types of shaft-type and box-type fixing components. Users can flexibly mount shaft-type and box-type fixing components on the mounting frame 2 according to the characteristics of the cargo, further expanding the functionality and applicability of this multi-functional warehouse trailer. Through holes are opened on the side wall of the longitudinal beam 9 and copper sleeves 10 are fixedly installed, which reduces wear between components, reduces the frequency of equipment failures caused by wear, reduces the number of equipment maintenance and replacement parts, thereby reducing maintenance costs and improving the uptime and efficiency of the equipment.

[0033] like Figure 4 As shown, the shaft-type fixing assembly includes a bracket 12; a first U-shaped base 14 is fixedly installed at both corners of the bottom surface of the bracket 12; an arc-shaped plate 13 is fixedly installed on the top surface of the bracket 12; a first through hole 19 is formed on the first U-shaped base 14 to fit a copper sleeve 10. The box-type fixing assembly includes a box body 15; a second U-shaped base 16 is fixedly installed on the bottom surface of the box body 15; a second through hole is formed on the second U-shaped base 16 to fit a copper sleeve 10. The box body 15 is generally shell-shaped with an open top surface; threaded holes are formed on all the peripheral walls of the box body 15.

[0034] The bracket 12 has a first U-shaped base 14 at each of its two corners, which precisely engages with the copper sleeve 10 on the side wall of the longitudinal beam 9 of the mounting frame 2. It is secured by connecting parts such as pins passing through the first through hole 19 in the base and the copper sleeve 10, ensuring the shaft fixing assembly is firmly installed and accurately positioned, preventing displacement during transportation and providing a reliable foundation for fixing shaft items. The arc-shaped plate 13 fixed to the top surface of the bracket 12 closely matches the cylindrical shape of the shaft item, increasing the contact area, dispersing pressure, and preventing damage to the shaft surface. It also effectively prevents the shaft item from rolling or shaking during transportation, improving transportation safety. The first U-shaped base 14, in conjunction with the copper sleeve 10, has a first through hole 19. This allows for simple installation of the shaft fixing assembly by aligning the connecting parts with the first through hole 19, eliminating the need for complex positioning and calibration processes. This simple and quick installation significantly reduces installation time, improves work efficiency, and facilitates rapid replacement or adjustment of the shaft fixing assembly's position in different scenarios. A second U-shaped base 16 fixedly mounted on the bottom surface of the box body 15 can mate with the copper sleeve 10. The box body 15 is a shell-shaped structure with an open top and is designed with box feet. Placing the box feet inside the box body 15 effectively limits the horizontal displacement of the box during transportation, preventing the box from sliding or tipping over on the flatbed truck, providing a stable placement platform for boxed goods, and ensuring transportation safety. This fixing component design is suitable for boxed items of various sizes and shapes. As long as the box feet can be placed inside the box body 15, effective fixing can be achieved, greatly improving the versatility of the multi-functional warehouse trailer for boxed goods and meeting the transportation needs of different types of boxed goods. Threaded holes on the perimeter of the box body 15 allow bolts to be passed through the threaded holes to abut against the box feet for fixing. The operation is simple and convenient, further enhancing the fixing effect of boxed goods and ensuring the stability of boxed goods during transportation.

[0035] In practical use, the number of mounting brackets 2 to be installed is determined according to the type and quantity of the transported goods. Align the mounting holes 18 on the crossbeam 11 of the mounting bracket 2 with the pin holes 17 in each set of fixing holes on the chassis 6, and insert the pins into the pin holes 17 to fix the mounting bracket 2 on the chassis 6.

[0036] For transporting shaft-type items, place the first U-shaped base 14 at both corners of the bottom surface of the shaft fixing component bracket 12 onto the longitudinal beam 9 of the mounting frame 2. Use pins or other connecting parts to pass through the first through hole 19 on the first U-shaped base 14 and the copper sleeve 10 on the longitudinal beam 9 to install the shaft fixing component onto the mounting frame 2. When installing multiple shaft fixing components, adjust their positions on the mounting frame 2 according to the length and quantity of the shaft items. Place the shaft items on the arc plate 13 of the installed shaft fixing component, ensuring that the shaft items are tightly fitted to the arc plate 13. The arc plate 13 increases the contact area with the shaft items, preventing them from rolling or shaking. Using several ratchet tighteners 5 spaced along the length direction on both sides of the chassis 6, select the appropriate ratchet tightener 5 and use ropes or straps to further secure the shaft items to the flatbed 1, preventing displacement, shaking, or slippage of the goods during transportation.

[0037] When transporting boxed items, align the second U-shaped base 16 on the bottom surface of the box-fixing assembly 15 with the copper sleeve 10 on the side wall of the longitudinal beam 9 of the mounting frame 2. Use a pin or other connector to pass through the second through hole on the second U-shaped base 16 and the copper sleeve 10 to install the box-fixing assembly. Place the bottom of the boxed goods into the box 15. If further securing is needed, bolts can be used through the threaded holes on the perimeter of the box 15 to reinforce the bottom of the boxed goods. Accurately place the bottom of the boxed goods into the box 15 of the box-fixing assembly. If the boxed goods are large or heavy, multiple box-fixing assemblies can be used simultaneously and further secured with bolts to prevent the box from sliding or tipping over during transport. Using the ratchet tensioners 5 spaced along the length of the chassis 6 on both sides, select a suitable ratchet tensioner 5 and use ropes or straps to further secure the boxed goods to the flatbed trolley 1 to prevent displacement, shaking, or slippage during transport.

[0038] During transportation, connect the tow bar 8 at the front of the flatbed truck 1 to a tractor, forklift, or other power equipment, and use an external power source to propel the flatbed truck 1 to transport the goods. During transportation, carefully observe the securing of the goods to ensure safe transport. Upon arrival at the destination, first untie the ropes or straps on the ratchet tensioner 5, and then unload the goods.

[0039] When disassembling shaft-type or box-type fixing components, remove connecting parts such as pins and place them back into the receiving box 20 on the rear bottom of the chassis 6. Finally, disassemble the mounting bracket 2.

[0040] How this multi-functional warehouse trailer works:

[0041] Flatbed truck movement principle: The wheels 7 mounted on the bottom of the chassis 6 use rolling friction instead of sliding friction, greatly reducing the friction force when the flatbed truck 1 moves, so that only a small traction force is needed to move the flatbed truck 1. The tow bar 8 mounted at the front end of the chassis 6 facilitates connection with external power equipment, transmitting external power to the flatbed truck 1 to achieve long-distance transportation.

[0042] Installation principles of shaft-type and box-type fixing components:

[0043] The flatbed trailer 1 has two sets of fixing holes on its chassis 6. Each set consists of six pin holes 17 arranged in a 2×3 matrix. The crossbeam 11 of the mounting frame 2 has mounting holes 18 that mate with the pin holes 17. A pin passes through the mounting holes 18 and pin holes 17, allowing for a detachable connection between the mounting frame 2 and the chassis 6. This matrix-style fixing method, compared to single-point fixing, significantly enhances the stability and reliability of the mounting frame 2 on the chassis 6, effectively preventing it from shaking or shifting during transportation due to vehicle vibrations. Simultaneously, the regular and uniform arrangement of the fixing holes facilitates standardized production of the flatbed trailer 1 and related components, improving production efficiency, reducing production costs, and enhancing the versatility and interchangeability of the entire multi-functional warehouse trailer, facilitating later maintenance and parts replacement. The first U-shaped base 14 of the axle-type fixing component and the second U-shaped base 16 of the box-type fixing component are both installed by mates with the copper sleeves 10 on the side wall of the longitudinal beam 9 of the mounting frame 2. Pins and other connecting components pass through the first through hole 19 on the first concave base 14, the second through hole on the second concave base 16, and the copper sleeve 10, achieving a stable connection between the shaft-type fixing components and the box-type fixing components and the mounting bracket 2. The copper sleeve 10 not only reduces wear between components, lowers the frequency of equipment failure, and extends the service life of the equipment, but also makes the installation and disassembly of the fixing components more convenient and quick, without the need for complex positioning and calibration processes.

[0044] Cargo securing principle:

[0045] When securing shaft-type goods, the arc-shaped plate 13 fixed to the top surface of the bracket 12 of the shaft-fixing assembly perfectly matches the cylindrical shape of the shaft. When the shaft is placed on the arc-shaped plate 13, the plate fits tightly against the shaft surface, increasing the contact area and evenly distributing the weight of the shaft, preventing damage to the shaft surface. It also effectively prevents the shaft from rolling or shaking during transport, ensuring the safety of the shaft goods during transport.

[0046] When securing boxed goods, the box body 15 is a shell-like structure with an open top. Combined with the box's foot design, placing the foot inside the box body 15 effectively limits horizontal displacement during transport. Threaded holes on the perimeter of the box body 15 allow bolts to pass through and engage with the box's feet, further enhancing the securing effect and preventing the box from sliding or tipping over on the flatbed, ensuring the stability of the transported goods. Furthermore, several ratchet tensioners 5, spaced along the length of the chassis 6 on both sides, can tighten ropes or straps to firmly secure the goods to the flatbed 1, depending on their size and shape, providing additional safety for the transport of various types of goods.

[0047] By providing mounting holes on the flatbed trailer 1, mounting racks 2 can be flexibly installed. Shaft-type and box-type fixing components can be detachably installed on the mounting racks 2, enabling this multi-functional warehouse trailer to transport various types of goods. Users can freely choose the number of mounting racks 2 and the different types of fixing components mounted on them, depending on the type of goods being transported. They can even use only the flatbed trailer 1 to transport other types of goods, thus breaking the limitations of traditional warehouse trailers with their single function, greatly expanding their applicability, meeting the transportation needs of different types of goods, and improving logistics efficiency. Furthermore, the detachable installation method of each component makes the installation, disassembly, maintenance, and management of the equipment simpler and more convenient, reducing equipment procurement, maintenance, and management costs.
