Description

Technical Field

[0001] This utility model relates to the field of warehousing and logistics technology, and more specifically, to a hoist. Background Technology

[0002] Multi-depth automated storage systems for palletized goods are now widely used in logistics warehousing. Elevators are a core component of these systems; single-column high-speed elevators can quickly and efficiently deliver pallets into or out of different shelving levels. Inter-level conveying can utilize chains, rollers, or other methods. For applications with openings and compact dimensions, existing single-column elevators cannot effectively adapt to various scenarios, requiring expanded opening sizes to accommodate the elevator layout, resulting in a larger footprint. For double-column elevators, there are two layout options: face-to-face and back-to-back. Face-to-face layouts increase the opening's x-axis dimension, failing to reduce the footprint, and the columns can only connect to the perimeter, leading to poor stability. Back-to-back layouts also increase the opening's x-axis dimension, allowing for column interconnection, but requiring sufficient maintenance space for the lifting units, resulting in greater distances between them, and the connecting supports also increase costs.

[0003] Therefore, how to design a hoist that can reduce the equipment's footprint and improve its stability has become an urgent problem to be solved. Utility Model Content

[0004] This invention aims to at least solve problems such as large equipment footprint and poor stability.

[0005] Therefore, the first aspect of this utility model provides a hoist.

[0006] In view of the above, the first aspect of the present invention provides a hoist, comprising: at least two hoisting components, the at least two hoisting components being interconnected; at least a portion of the structure of the two hoisting components overlapping along the length direction of the hoisting components, and at least a portion of the structure of the two hoisting components being arranged side by side along the width direction of the hoisting components.

[0007] The hoist provided by this utility model features at least two interconnected lifting components, with some structures overlapping in the length direction and others arranged side-by-side in the width direction. This results in a more compact layout, effectively reducing the equipment's footprint and improving space utilization. Simultaneously, the interconnection between the lifting components enhances the overall structural stability of the equipment, making it more reliable and safer under high-speed operation and heavy loads. This design eliminates the need for expanding the opening size as required by existing single-column hoists and avoids the shortcomings of face-to-face and back-to-back layouts in double-column hoists. It better adapts to openings of different sizes and shapes, enhancing layout flexibility. Furthermore, the hoist structure of this application reduces material usage and the number of connecting parts while ensuring performance, thereby lowering manufacturing and maintenance costs and improving the equipment's economic efficiency and market competitiveness.

[0008] Understandably, in some applications, at least two hoists are required to operate in conjunction. Therefore, related technologies typically use two independent, single-column hoists, resulting in a significant footprint. Connecting two hoists together, such as face-to-face or back-to-back arrangements, also occupies a large area. The back-to-back staggered layout proposed in this application solves this problem, effectively reducing the equipment's footprint and improving space utilization.

[0009] In some embodiments, the lifting component may optionally include: a support column; a driving unit disposed on one side of the lifting component along the length direction of the lifting component; and a load-bearing component disposed on the other side of the lifting component along the length direction of the lifting component; wherein the driving unit is connected to the load-bearing component and is used to drive the load-bearing component to move in a vertical direction.

[0010] In these embodiments, the lifting assembly includes a support column, a drive unit, and a load-carrying assembly. The drive unit and the load-carrying assembly are respectively disposed on both sides of the lifting assembly, and the drive unit is connected to the load-carrying assembly to drive it to move vertically. This structural design makes the hoist more compact in layout, effectively reducing the equipment's footprint and improving space utilization. The support column provides stable support for the hoist, enhancing the overall structural stability of the equipment and making it more reliable and safer under high-speed operation and heavy load conditions.

[0011] Understandably, since each lifting component includes a support column, the lifting machine of this application includes at least two support columns, which further improves the stability of the equipment compared to a solution with only one support column. Similarly, the load-carrying components also include at least two, thus improving the conveying efficiency.

[0012] In some embodiments, optionally, there are two lifting components, and at least a portion of the structure of the two support columns of the two lifting components overlaps along the length direction of the lifting components, and at least a portion of the structure of the two support columns of the two lifting components are arranged side by side along the width direction of the lifting components.

[0013] In these embodiments, the hoist includes two lifting components. Along the length of the lifting components, at least a portion of the support columns of the two lifting components overlap, while in the width direction, at least a portion of the two support columns are arranged side-by-side. This design makes the hoist more compact in layout, effectively reducing the equipment's footprint and improving space utilization. Simultaneously, the overlapping and side-by-side arrangement of the support columns enhances the overall structural stability of the equipment, making it more reliable and safer under high-speed operation and heavy load conditions. Furthermore, this structural design eliminates the need to expand the opening size as required by existing single-column hoists and avoids the shortcomings of face-to-face and back-to-back layouts of double-column hoists, better adapting to openings of different sizes and shapes and enhancing layout flexibility.

[0014] In some embodiments, optionally, the number of lifting components is two, and two support columns are disposed between the two load-bearing components along the length direction of the lifting components.

[0015] In these embodiments, the hoist includes two lifting components, and the support columns of these two lifting components are arranged between two load-carrying components along the length of the lifting components. This layout makes the hoist more compact in the length direction, effectively reducing the footprint of the equipment and improving space utilization.

[0016] Meanwhile, the support columns are located between the load-bearing components, which can better distribute the forces generated by the load-bearing components during operation, enhance the overall structural stability of the equipment, and make it more reliable and safe under high-speed operation and heavy load conditions.

[0017] In some embodiments, the drive unit may optionally include: a fixed base mounted on a support column; a drum rotatably mounted on the fixed base; a lifting belt wound around the drum and connected to a load assembly; and a motor disposed on the fixed base and connected to the drum for driving the drum to rotate.

[0018] In these embodiments, the drive unit of the hoist includes a fixed base, a drum, a lifting belt, and a motor. The fixed base is mounted on a support column, the drum is rotatably mounted on the fixed base, the lifting belt is wound around the drum and connected to the load assembly, and the motor is located on the fixed base and connected to the drum to drive the drum to rotate. This structural design of the drive unit makes power transmission more direct and efficient. The motor drives the drum to rotate, which in turn drives the lifting belt to move, thereby realizing the lifting and lowering of the load assembly. Compactly mounting the various components of the drive unit on the support column not only optimizes the spatial layout of the hoist and reduces its footprint, but also enhances the overall stability of the equipment. This layout makes the power transmission of the hoist more stable during operation, reduces energy loss, and improves lifting efficiency. At the same time, the reasonable component layout facilitates installation and maintenance, reducing equipment maintenance costs and time.

[0019] Furthermore, this design avoids potential failure points caused by complex transmission structures, improves the reliability and durability of the equipment, and further enhances the adaptability and competitiveness of the elevator in logistics and warehousing systems.

[0020] In some embodiments, the lifting assembly may optionally include a first lifting assembly and a second lifting assembly, wherein a drum on the first lifting assembly is disposed between a motor on the first lifting assembly and the second lifting assembly; and a drum on the second lifting assembly is disposed between a motor on the second lifting assembly and the first lifting assembly.

[0021] In these embodiments, the hoist includes a first hoisting component and a second hoisting component. A drum on the first hoisting component is disposed between the motor of that component and the second hoisting component, while a drum on the second hoisting component is disposed between the motor of that component and the first hoisting component. This relative arrangement of the drum and motor makes the hoist's structure more compact in the width direction, effectively reducing the equipment's footprint and improving space utilization. Simultaneously, this layout facilitates direct power transmission, reduces energy loss during power transmission, and improves hoisting efficiency.

[0022] Furthermore, placing the drum between the motor and another lifting component reduces the angle of inclination formed when the lifting belt connects to the fixed pulley assembly on the support column, avoiding interference with the opening. This design avoids interference problems caused by unreasonable component layout, better adapts to openings of different sizes and shapes, and enhances layout flexibility.

[0023] In some embodiments, the drive unit may optionally include: an adjusting arm rotatably disposed on a fixed base, and a motor mounted on the adjusting arm.

[0024] In these embodiments, the drive unit further includes an adjusting arm rotatably mounted on a fixed base, with the motor mounted on the adjusting arm. This design allows the motor position to be adjusted by rotating the adjusting arm, thereby optimizing the tension and alignment accuracy of the lifting belt and ensuring smooth operation of the load assembly during lifting. The introduction of the adjusting arm not only improves the flexibility of equipment installation and commissioning but also facilitates maintenance and adjustments during equipment operation, reducing maintenance costs and time.

[0025] In some embodiments, the loading assembly may optionally include: a loading platform, movably disposed on a support column and connected to a drive unit, the drive unit being capable of driving the loading platform to move in a vertical direction; and guide wheels, rotatably mounted on the loading platform, for guiding the movement direction of the loading assembly.

[0026] In these embodiments, the lifting mechanism's carrying component includes a carrying platform and guide wheels. The carrying platform is movably mounted on a support column and connected to a drive unit, which drives the carrying platform to move vertically. The guide wheels are rotatably mounted on the carrying platform to guide the movement direction of the carrying component. The close connection between the carrying platform and the drive unit ensures direct and efficient power transmission, resulting in smooth operation of the carrying platform during lifting and lowering, thus improving lifting efficiency. The guide wheels further enhance the stability and accuracy of the carrying platform during movement, avoiding safety hazards and cargo damage caused by deviation or swaying.

[0027] Furthermore, this structural design facilitates installation and maintenance, reducing equipment maintenance costs and time. By optimizing the layout and function of the cargo-carrying components, the reliability and durability of the equipment are further improved while ensuring performance, enhancing its adaptability and market competitiveness in logistics and warehousing systems.

[0028] In some embodiments, the loading assembly may optionally include a conveyor disposed on the loading platform for transporting goods on the loading platform.

[0029] In these embodiments, the loading assembly also includes a conveyor mounted on the loading platform for transporting goods on the platform. This design enables the elevator to not only rapidly lift and lower goods vertically but also effectively transport goods horizontally, further improving the automation level and operational efficiency of the logistics warehousing system. The combination of the conveyor and elevator makes the transfer of goods between different shelf levels smoother and more efficient, reducing the dwell time of goods during transfer. Simultaneously, this integrated design optimizes the equipment layout, avoiding the space required for separately configured conveyor equipment, further reducing the equipment's footprint and improving space utilization. Furthermore, the inclusion of the conveyor does not increase the complexity of the equipment; instead, through reasonable layout and integrated design, it reduces the overall cost of the system, improving the equipment's economic viability and market competitiveness.

[0030] In some embodiments, the number of lifting components may be two, and the lifting machine may further include a connector disposed between the two lifting components for connecting the two lifting components.

[0031] In these embodiments, the hoist includes two lifting components and a connector disposed between the two lifting components for connecting them. This design allows the two lifting components to be tightly integrated into a stable overall structure, enhancing the hoist's stability and load-bearing capacity. The connector not only optimizes the hoist's layout, making it more compact in the width direction and reducing the equipment's footprint, but also improves the equipment's overall integrity and coordination. By rationally setting the position and structure of the connector, the relative position and angle between the two lifting components can be further adjusted to accommodate openings of different sizes and shapes, enhancing the hoist's layout flexibility and adaptability. Furthermore, this connection method facilitates equipment installation, commissioning, and maintenance, reducing maintenance costs and time, improving equipment reliability and economy, and further enhancing its application value and market competitiveness in logistics and warehousing systems.

[0032] In some embodiments, the hoist may optionally include at least one fixing member disposed on the hoisting assembly for fixing the hoist.

[0033] In these embodiments, the hoist includes at least one fixing member disposed on the hoisting assembly for connection to the external environment to secure the hoist. This design ensures the stability and safety of the hoist during operation, preventing swaying or displacement of the equipment when lifting or lowering goods. The fixing member allows the hoist to be firmly installed on the ground, openings, or other supporting structures, enhancing the overall stability of the equipment, especially under high-speed operation and heavy load conditions, effectively reducing the risk of vibration and swaying.

[0034] In some embodiments, the fastener may optionally include at least one of a rope, a bracket, or a bolt assembly.

[0035] In these embodiments, the fixing element can be at least one of rope, bracket, and bolt assembly. The rope fixing element has a certain degree of flexibility and strength, allowing the hoist to be secured to the ground or building structure. Rope fixing elements are suitable for applications requiring elasticity and cushioning, absorbing vibrations generated during equipment operation. Bracket fixing elements are typically made of metal, possessing high strength and stability. The bracket can be designed to be adjustable to accommodate different installation heights and angles, enhancing the equipment's adaptability. The bolt assembly includes bolts and nuts, which, through their combination, securely fix the hoist to the ground or other supporting structures. Bolts can be pre-embedded in concrete foundations or fixed to existing structures using expansion bolts, ensuring the hoist's stability.

Detailed Implementation

[0049] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0050] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0051] The following reference Figures 1 to 9 This invention describes a hoist proposed according to some embodiments of the present invention.

[0052] According to an embodiment of the first aspect of the present invention, such as Figures 1 to 9 As shown, the first aspect of this utility model discloses a hoist, including at least two hoisting components 1, which are interconnected. Along the length direction of the hoisting components 1 (e.g., ... Figure 9 (in the direction indicated by L), at least a portion of the structures of the two lifting components 1 overlap, along the width direction of the lifting component 1 (e.g., ...). Figure 9 (in the direction indicated by W), at least some of the structures of the two lifting components 1 are arranged side by side.

[0053] The hoist provided by this utility model features at least two interconnected lifting components 1, with some structures overlapping in the length direction and others arranged side-by-side in the width direction. This results in a more compact layout, effectively reducing the equipment's footprint and improving space utilization. Simultaneously, the interconnection between the lifting components 1 enhances the overall structural stability of the equipment, making it more reliable and safer under high-speed operation and heavy loads. This design eliminates the need to expand the opening 17 size as required by existing single-column hoists and avoids the shortcomings of face-to-face and back-to-back layouts in double-column hoists. It better adapts to openings 17 of different sizes and shapes, enhancing layout flexibility. Furthermore, the hoist structure of this application, while ensuring performance, reduces material usage and the number of connecting parts, thereby lowering manufacturing and maintenance costs and improving the equipment's economic efficiency and market competitiveness.

[0054] Understandably, in some applications, at least two hoists are required to operate in conjunction. Therefore, related technologies typically use two independent, single-column hoists, resulting in a significant footprint. Connecting two hoists together, such as face-to-face or back-to-back arrangements, also occupies a large area. The back-to-back staggered layout proposed in this application solves this problem, effectively reducing the equipment's footprint and improving space utilization.

[0055] In this design, at least two lifting components 1 partially overlap in the length direction. This overlap is not a complete coincidence, but rather a precisely designed overlap that provides structural support and connection without excessive space occupation. For example, special mortise and tenon structures or snap-fit ​​connections may be used in the overlapping area, where protrusions and grooves of specific shapes fit together, ensuring a stable connection and reducing the number of connecting parts to a certain extent, thus simplifying the structure.

[0056] In some embodiments, optionally, such as Figure 2 , Figure 4 and Figure 8 As shown, the lifting assembly 1 includes: a support column 10; a drive unit 11, disposed on one side of the lifting assembly 1 along its length; and a load assembly 12, disposed on the other side of the lifting assembly 1 along its length. The drive unit 11 is connected to the load assembly 12 and is used to drive the load assembly 12 along the vertical direction (e.g., ...). Figure 1 Move in the direction indicated by H.

[0057] In these embodiments, the lifting assembly 1 includes a support column 10, a drive unit 11, and a load assembly 12. The drive unit 11 and the load assembly 12 are respectively disposed on both sides of the lifting assembly 1, and the drive unit 11 is connected to the load assembly 12 to drive it to move vertically. This structural design makes the hoist more compact in layout, effectively reducing the equipment's footprint and improving space utilization. The support column 10 provides stable support for the hoist, enhancing the overall structural stability of the equipment and making it more reliable and safer under high-speed operation and heavy load conditions.

[0058] Understandably, since each lifting component 1 includes a support column 10, the lifting machine of this application includes at least two support columns 10, which further improves the stability of the equipment compared to a solution with only one support column 10. Similarly, the load-carrying component 12 also includes at least two, thus improving the conveying efficiency.

[0059] The connection between the drive unit 11 and the load assembly 12 is not limited to a direct connection, but can be an indirect connection. For example, in some scenarios with high requirements for spatial layout, they can be connected through multiple high-precision pulleys.

[0060] Furthermore, these pulleys are made of wear-resistant materials and have a polished surface to reduce friction and improve transmission efficiency. The installation positions of the pulleys are precisely calculated and designed to ensure uniform force transmission during operation and to prevent tilting or swaying of the load-bearing assembly 12.

[0061] Furthermore, the support column 10 can be made of high-strength alloy material and forged using a special forging process, possessing excellent compressive and bending resistance. Its surface is treated with anti-corrosion coating, which not only extends its service life but also allows it to adapt to various complex working environments, such as damp basements and high-dust industrial workshops.

[0062] In some embodiments, optionally, such as Figure 2 and Figure 9 As shown, there are two lifting components 1. Along the length direction of the lifting components 1, at least a portion of the structure of the two support columns 10 of the two lifting components 1 overlaps. Along the width direction of the lifting components 1, at least a portion of the structure of the two support columns 10 of the two lifting components 1 are arranged side by side.

[0063] In these embodiments, the hoist includes two lifting components 1. Along the length of the lifting components 1, at least a portion of the support columns 10 of the two lifting components 1 overlap, while in the width direction, at least a portion of the two support columns 10 are arranged side-by-side. This design makes the hoist more compact in layout, effectively reducing the equipment's footprint and improving space utilization. Simultaneously, the overlapping and side-by-side arrangement of the support columns 10 enhances the overall structural stability of the equipment, making it more reliable and safer under high-speed operation and heavy load conditions. Furthermore, this structural design eliminates the need to expand the opening 17 size as required by existing single-column hoists, and avoids the shortcomings of face-to-face and back-to-back layouts of double-column hoists. It can better adapt to openings 17 of different sizes and shapes, enhancing layout flexibility.

[0064] Meanwhile, the hoist of this application, with its unique overlapping and side-by-side layout of the two hoisting components 1 and support columns 10, can be flexibly adjusted according to openings 17 of different sizes and shapes. Whether the opening 17 is round, square, or irregularly shaped, it can be well adapted by reasonably arranging the support columns 10, thereby enhancing the layout flexibility, broadening the application scenarios of the hoist, and enabling it to better meet various practical engineering needs.

[0065] In some embodiments, optionally, the number of lifting components 1 is two, and along the length direction of the lifting components 1, two support columns 10 are disposed between two load-bearing components 12.

[0066] In these embodiments, the hoist includes two lifting components 1, and the support columns 10 of these two lifting components 1 are arranged between two load-carrying components 12 along the length direction of the lifting components 1. This layout makes the hoist more compact in the length direction, effectively reducing the footprint of the equipment and improving space utilization.

[0067] Meanwhile, the support column 10 is located between the load-bearing components 12, which can better disperse the force generated by the load-bearing components 12 during operation, enhance the overall structural stability of the equipment, and make it more reliable and safe under high-speed operation and heavy load conditions.

[0068] Furthermore, compared to the traditional layout where the support column 10 is located outside the carrying component 12, this design effectively avoids the problem of increased overall equipment size due to the support column 10 occupying extra space, thus significantly reducing the equipment's footprint. For example, in multi-level automated warehouses with limited space, this compact elevator layout can achieve efficient operation within limited aisle width, improving warehouse space utilization, enabling the warehouse to store more goods, and enhancing warehousing efficiency.

[0069] In some embodiments, optionally, such as Figure 8As shown, the drive unit 11 includes: a fixed base 110, mounted on the support column 10; a drum 112, rotatably mounted on the fixed base 110; a lifting belt 114, wound around the drum 112 and connected to the load assembly 12; and a motor 116, disposed on the fixed base 110 and connected to the drum 112, for driving the drum 112 to rotate.

[0070] In these embodiments, the drive unit 11 of the hoist includes a fixed base 110, a drum 112, a lifting belt 114, and a motor 116. The fixed base 110 is mounted on the support column 10, the drum 112 is rotatably mounted on the fixed base 110, the lifting belt 114 is wound around the drum 112 and connected to the load assembly 12, and the motor 116 is located on the fixed base 110 and connected to the drum 112 to drive the drum 112 to rotate. This structural design of the drive unit 11 makes power transmission more direct and efficient. The motor 116 drives the drum 112 to rotate, which in turn drives the lifting belt 114 to move, thereby realizing the lifting and lowering of the load assembly 12. The compact mounting of the various components of the drive unit 11 on the support column 10 not only optimizes the spatial layout of the hoist and reduces its footprint, but also enhances the overall stability of the equipment. This layout makes the power transmission of the hoist more stable during operation, reduces energy loss, and improves lifting efficiency. At the same time, the reasonable component layout facilitates installation and maintenance, reducing equipment maintenance costs and time.

[0071] Furthermore, this design avoids potential failure points caused by complex transmission structures, improves the reliability and durability of the equipment, and further enhances the adaptability and competitiveness of the elevator in logistics and warehousing systems.

[0072] In some embodiments, optionally, such as Figure 1 and Figure 2 As shown, the lifting assembly 1 also includes a fixed pulley assembly 100, which is mounted on the support column 10. The lifting belt 114 is connected to the load assembly 12 after cooperating with the fixed pulley assembly 100.

[0073] The fixed pulley assembly 100 can be set on the top of the support column 10, which can maximize the lifting range of the hoist.

[0074] In some embodiments, the lifting assembly 1 may optionally include a first lifting assembly 13 and a second lifting assembly 14, wherein a drum 112 on the first lifting assembly 13 is disposed between a motor 116 on the first lifting assembly 13 and the second lifting assembly 14; and a drum 112 on the second lifting assembly 14 is disposed between a motor 116 on the second lifting assembly 14 and the first lifting assembly 13.

[0075] In these embodiments, the hoist includes a first hoisting assembly 13 and a second hoisting assembly 14. A drum 112 on the first hoisting assembly 13 is disposed between the motor 116 of that assembly and the second hoisting assembly 14, while a drum 112 on the second hoisting assembly 14 is disposed between the motor 116 of that assembly and the first hoisting assembly 13. This relative arrangement of the drum 112 and the motor 116 makes the hoist's structure more compact in the width direction, effectively reducing the equipment's footprint and improving space utilization. Simultaneously, this layout facilitates direct power transmission, reduces energy loss during power transmission, and improves hoisting efficiency.

[0076] Meanwhile, during the operation of the hoist, the lifting belt 114 needs to be guided and steered by the fixed pulley assembly 100 on the support column 10. Therefore, placing the drum 112 between the motor 116 and another lifting assembly 1 can reduce the inclination angle formed when the lifting belt 114 connects with the fixed pulley assembly 100 on the support column 10. A smaller inclination angle can prevent the lifting belt 114 from interfering with the surrounding structure of the opening 17 during operation. Regardless of whether the opening 17 is square, round, or other irregularly shaped, this hoist can flexibly adapt to openings 17 of different sizes and shapes thanks to this reasonable layout design, effectively avoiding interference problems caused by unreasonable component layout, significantly enhancing layout flexibility, and broadening the application range of the hoist in various complex environments, enabling it to better meet diverse engineering needs.

[0077] In some embodiments, optionally, such as Figure 8 As shown, the drive unit 11 also includes: an adjusting arm 118, which is rotatably mounted on the fixed base 110, and a motor 116 mounted on the adjusting arm 118.

[0078] In these embodiments, the drive unit 11 further includes an adjusting arm 118, which is rotatably mounted on the fixed base 110, and the motor 116 is mounted on the adjusting arm 118. This design allows the position of the motor 116 to be adjusted by rotating the adjusting arm 118, thereby optimizing the tension and alignment accuracy of the lifting belt 114 and ensuring smooth operation of the load assembly 12 during lifting. The introduction of the adjusting arm 118 not only improves the flexibility of equipment installation and commissioning but also facilitates maintenance and adjustment during equipment operation, reducing maintenance costs and time.

[0079] In some embodiments, the drive unit 11 may optionally include a bearing housing 1100 and a pin 1180, and the adjusting arm 118 is rotatably mounted on the fixed base 110 via the bearing housing 1100 and the pin 1180.

[0080] In some embodiments, the drive unit 11 may optionally include: snap rings 1182 disposed at both ends of the pin 1180 to prevent the pin 1180 from falling off the bearing housing 1100.

[0081] In some embodiments, optionally, such as Figure 7 As shown, the loading assembly 12 includes: a loading platform 120, which is movably disposed on the support column 10 and connected to the drive unit 11, the drive unit 11 being able to drive the loading platform 120 to move in the vertical direction; and a guide wheel 122, which is rotatably mounted on the loading platform 120 and is used to guide the movement direction of the loading assembly 12.

[0082] In these embodiments, the lifting assembly 12 includes a platform 120 and guide wheels 122. The platform 120 is movably mounted on the support column 10 and connected to the drive unit 11, which drives the platform 120 to move vertically. The guide wheels 122 are rotatably mounted on the platform 120 to guide the movement of the lifting assembly 12. The close connection between the platform 120 and the drive unit 11 ensures direct and efficient power transmission, making the platform 120 run smoothly during lifting and improving lifting efficiency. The guide wheels 122 further enhance the stability and accuracy of the platform 120 during movement, avoiding safety hazards and cargo damage caused by deviation or swaying.

[0083] Furthermore, this structural design facilitates installation and maintenance, reducing equipment maintenance costs and time. By optimizing the layout and function of the cargo-carrying component 12, the reliability and durability of the equipment are further improved while ensuring performance, enhancing its adaptability and market competitiveness in logistics and warehousing systems.

[0084] In some embodiments, the loading assembly 12 may optionally include a conveyor 124 disposed on the loading platform 120 for conveying goods on the loading platform 120.

[0085] In these embodiments, the loading assembly 12 also includes a conveyor 124 disposed on the loading platform 120 for conveying goods on the loading platform 120. This design enables the elevator to not only achieve rapid vertical lifting of goods but also efficient horizontal conveying, further improving the automation level and operational efficiency of the logistics warehousing system. The combination of the conveyor 124 and the elevator makes the transfer of goods between different shelf levels smoother and more efficient, reducing the dwell time of goods during the transfer process. At the same time, this integrated design optimizes the layout of the equipment, avoids the space required for separately configuring conveyor equipment, further reduces the equipment's footprint, and improves space utilization. In addition, the inclusion of the conveyor 124 does not increase the complexity of the equipment; on the contrary, through reasonable layout and integrated design, it reduces the overall cost of the system and improves the economic efficiency and market competitiveness of the equipment.

[0086] In some embodiments, optionally, such as Figure 3 , Figure 5 and Figure 6 As shown, there are two lifting components 1. The lifting machine also includes a connector 15, which is disposed between the two lifting components 1 for connecting the two lifting components 1.

[0087] In these embodiments, the hoist includes two lifting components 1, and also includes a connector 15 disposed between the two lifting components 1 for connecting them. This design allows the two lifting components 1 to be tightly integrated into a stable overall structure, enhancing the stability and load-bearing capacity of the hoist. The connector 15 not only optimizes the layout of the hoist, making it more compact in the width direction and reducing the equipment's footprint, but also improves the overall integrity and coordination of the equipment. By rationally setting the position and structure of the connector 15, the relative position and angle between the two lifting components 1 can be further adjusted to accommodate openings 17 of different sizes and shapes, enhancing the layout flexibility and adaptability of the hoist. Furthermore, this connection method facilitates the installation, commissioning, and maintenance of the equipment, reducing maintenance costs and time, improving the reliability and economy of the equipment, and further enhancing its application value and market competitiveness in logistics and warehousing systems.

[0088] To facilitate the connection of the two lifting components 1 using the connector 15, oblong holes can be provided on the two lifting components 1. This allows for quick connection even if the positions of the two lifting components 1 are misaligned. The direction of the oblong holes is not limited and can be set according to actual needs.

[0089] In some embodiments, the connector 15 may optionally be welded to the lifting assembly 1 or connected by bolts.

[0090] In some embodiments, the hoist may optionally include at least one fixing member 16 disposed on the hoisting assembly 1 for fixing the hoist.

[0091] In these embodiments, the hoist includes at least one fixing member 16 disposed on the hoisting assembly 1 for connecting to the external environment to secure the hoist. This design ensures the stability and safety of the hoist during operation, preventing swaying or displacement of the equipment when lifting or lowering goods. The fixing member 16 allows the hoist to be securely installed on the ground, opening 17, or other supporting structures, enhancing the overall stability of the equipment, especially under high-speed operation and heavy load conditions, effectively reducing the risk of vibration and swaying.

[0092] In some embodiments, the fastener 16 may optionally include at least one of a rope, a bracket, and a bolt assembly.

[0093] In these embodiments, the fixing element 16 can be at least one of a rope, a bracket, and a bolt assembly. The rope fixing element 16 possesses a certain degree of flexibility and strength, allowing the hoist to be secured to the ground or a building structure. The rope fixing element 16 is suitable for applications requiring elasticity and cushioning, capable of absorbing vibrations generated during equipment operation. The bracket fixing element 16 is typically made of metal, possessing high strength and stability. The bracket can be designed to be adjustable to accommodate different installation heights and angles, enhancing the equipment's adaptability. The bolt assembly includes bolts and nuts, which, through their combination, securely fix the hoist to the ground or other supporting structures. The bolts can be pre-embedded in a concrete foundation or fixed to an existing structure using expansion bolts, ensuring the hoist's stability.

[0094] According to an embodiment of the first aspect of this utility model, a hoist is provided in which two hoisting components are compactly placed back-to-back in a staggered manner within an opening. The motor of the hoisting unit component (drive unit) is positioned on the outer side and offset onto the column component, allowing the two back-to-back hoists to be staggered, reducing the dimension in the x-direction (length direction). The wire rope (hoisting belt) winds out from the inside of the drum, reducing the angle formed with the fixed pulley component and avoiding interference with the opening. Furthermore, the two hoisting components are connected by a middle connecting bracket (connector) and a top connecting bracket (connector), forming a whole and increasing the stability of the layout structure. Each hoisting component is further connected to the opening using an auxiliary support bracket (fixed component), further increasing the overall stability.

[0095] Each lifting assembly consists of a lifting unit assembly (drive unit), a column assembly, and a loading platform assembly (carrying assembly). The loading platform assembly is mounted on the column assembly via guide wheels (guide wheels), and the lifting unit assembly is fixed to the column assembly with screws, forming a complete lifting machine.

[0096] The lifting unit assembly includes a lifting motor, a drum base (fixed base), a drum, a wire rope (lifting belt), bearing housings, a torque arm (adjusting arm), a pin, and a retaining ring. Bearing housings are installed at both ends of the drum, which are then fixed to the drum base with screws. The lifting motor is connected to the torque arm with screws, and the torque arm, pin, and retaining ring are installed on the right side of the drum base.

[0097] The column assembly includes the column body assembly (support column), auxiliary support bracket (fixture), intermediate connecting bracket (connector), top connecting bracket (connector) and fixed pulley assembly.

[0098] The loading platform assembly (cargo assembly) comprises the loading platform body (loading platform), guide wheel assembly (guide wheels), and conveyor. The guide wheel assembly and conveyor are mounted on the loading platform body using screws.

[0099] This application has the following beneficial effects:

[0100] 1. The offset design and installation of the lifting unit components, along with the rope exit structure inside the drum, improves the space utilization of the dual lifting component layout.

[0101] 2. Improve the stability of dual-component integration by placing components closer together in the layout and connecting them to each other.
