Description

Technical Field

[0001] This utility model belongs to the field of scaffolding technology, specifically relating to a height-adjustable scaffolding. Background Technology

[0002] In construction, decoration, and equipment installation, scaffolding serves as a crucial support tool for high-altitude operations. Its structural stability, ease of use, and safety directly impact construction efficiency and worker safety. During construction, workers often encounter work positions at varying heights, necessitating adjustments to the scaffolding height. However, traditional scaffolding often employs fixed-height frame structures or adjusts height by adding or removing standard sections. This design suffers from the following significant drawbacks:

[0003] Traditional scaffolding (such as frame scaffolding and steel pipe coupler scaffolding) typically relies on manually adding or removing horizontal or vertical poles for height adjustment. This operation is not only cumbersome but also requires workers to carry multiple horizontal or vertical poles to the construction site for re-erection. First, workers need to prepare a large number of horizontal and vertical poles in advance according to the required construction height, which increases the transportation and management costs of materials. Second, during the erection process, workers need to install horizontal and vertical poles one by one and ensure that each component is securely connected. This is not only time-consuming and labor-intensive but also prone to structural instability due to improper human operation, increasing safety hazards. In addition, frequent erection and dismantling processes disrupt the continuity of construction, causing delays, especially when rapid height adjustments are needed to adapt to different construction locations, making this inefficient operation particularly inconvenient. Utility Model Content

[0004] In view of this, the present invention provides a height-adjustable scaffold to solve the problem that the height adjustment of traditional scaffolds usually relies on manually adding or removing the number of horizontal bars or vertical bars, which is cumbersome.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A height-adjustable scaffold includes a scaffold body with support plates mounted on it. The support plates are installed on four uprights of the scaffold body and are connected to the uprights via multiple connecting devices. Each connecting device includes a first locking ring and a second locking ring. One end of the first locking ring and the second locking ring are respectively hinged to the support plate and form a ring structure with each other. The ends of the first locking ring and the second locking ring away from the support plate are each provided with mounting blocks. Each mounting block has a socket hole with a screw inside the socket hole. Two nuts are screwed onto the screw, and the two nuts are located on one side of each mounting block.

[0007] In this technical solution, it should be noted that the support plate is used to support workers, ensuring their safety and stability when working at height. The support plate is typically made of wood with a thickness of at least 50mm or steel plate with a thickness of at least 1.5mm to ensure sufficient strength and durability. The support plate is installed on the four uprights of the scaffold body and is securely connected to the uprights through multiple connecting devices. The connecting devices include a first locking ring and a second locking ring, one end of which is hinged to the support plate, forming a complete circular structure. This design not only provides sufficient support but also allows for easy opening when needed, enabling height adjustment. Ladders are installed on both sides of the scaffold, providing workers with safe climbing access to easily reach the support plate for work. When the height of the support plate needs to be adjusted, workers can do so by tightening two nuts. These two nuts are mounted on a screw rod and move along the rod by rotation. The screw rod design allows for precise control of the nut movement, which in turn drives the two locking rings to clamp or loosen the uprights. This adjustment mechanism is simple and efficient, ensuring the stability of the support plate at different heights. In practice, firstly, the two nuts are pulled, moving them away from each other to release the restraints on the two mounting blocks, thus loosening the previously tight ring structure formed by the first and second locking rings. At this point, workers can move the support plate from its current position to the desired height. Once the desired height is reached, workers need to re-secure the support plate to the column: firstly, the first and second locking rings are rotated to their closed position, forming a complete ring structure that surrounds the column again. Then, the two nuts are pulled again, this time moving them closer together. As the nuts approach, they begin to apply pressure to the mounting blocks, forcing the first and second locking rings to gradually tighten, ultimately clamping the column securely. This process not only ensures the stability of the support plate at the new height but also guarantees the stability and safety of the entire scaffold structure, providing workers with a reliable working platform. Through this ingenious design, scaffold height adjustment becomes more convenient and efficient, greatly improving construction efficiency. This height-adjustable scaffolding meets the needs of different construction scenarios.

[0008] Preferably, each nut is further provided with a washer between it and the mounting block, and the washer is fitted onto the screw.

[0009] In this technical solution, it should be noted that: The shim can evenly distribute the pressure of the nut on the mounting block, preventing localized deformation or damage caused by concentrated pressure, thereby extending the service life of the mounting block and the bolt. The shim reduces direct contact between the nut and the mounting block, lowering friction and preventing wear on the mounting block surface when tightening or loosening the nut. The thickness of the shim provides a certain degree of fine-tuning space, allowing for more precise control of the clamping force of the locking ring on the column when tightening the nut, ensuring the stability and safety of the scaffolding. The shim also plays a role in preventing loosening, preventing the nut from loosening under vibration or impact, thus ensuring the reliability of the scaffolding connection. Depending on actual needs, shims of different thicknesses and materials can be selected to adapt to different construction environments and requirements, improving the versatility and flexibility of the scaffolding.

[0010] Preferably, the side wall of the column is provided with a plurality of slots that cooperate with the first locking ring and the second locking ring, and the plurality of slots are spaced apart along the height direction of the column.

[0011] In this technical solution, it should be noted that the slot is mainly used to provide stable support for the bottom of the locking ring. When the first and second locking rings close to form a circular structure and clamp the column, the slot can ensure that the bottom of the locking ring is stably embedded therein, preventing the locking ring from loosening and causing a safety accident.

[0012] Preferably, the support plate is also provided with four support rods that cooperate with the column. One end of the support rod is connected to the column through a connecting device, and the other end is connected to the support plate.

[0013] In this technical solution, it should be noted that the support rods are typically made of high-strength steel, such as Q235 or Q345B, which has excellent bending and shear resistance. This effectively distributes the weight of the support plate and the pressure exerted on workers during operation, thus reducing the burden on the support plate. The support rods, columns, and support plates form a triangular support structure, a design that significantly improves the overall stability and load-bearing capacity of the scaffolding. Due to its geometric stability, the triangular structure effectively resists lateral and vertical forces, reducing swaying and deformation of the scaffolding during use. Furthermore, the cross-sectional shape of the support rods typically uses a combination of double angle steel, double channel steel, H-shaped cross-section, or box-shaped cross-section. These cross-sectional shapes provide high lateral stiffness and compressive strength, ensuring the support rods remain stable even under heavy loads. With the auxiliary support of the support rods, the entire scaffolding structure is more stable, providing construction workers with a safe and reliable working platform. This design not only improves the stability and safety of the scaffolding but also makes it better adaptable to various complex construction scenarios.

[0014] Preferably, the support plate has guide rails at both ends along its length, and slide rails are slidably connected to the guide rails, with tool boxes mounted on the slide rails.

[0015] In this technical solution, it's important to note that the guide rails are typically made of high-strength steel, such as Q235 or Q345B, to ensure their load-bearing capacity and durability. This material choice not only supports the weight of the toolbox and its internal tools but also guarantees the stability and wear resistance of the guide rails during frequent use. The toolbox design prioritizes practicality and safety, typically employing lightweight yet robust materials such as aluminum alloy or engineering plastics to reduce overall weight while providing sufficient protection against tool damage during use. The toolbox interior can feature multiple compartments for categorizing and storing different tools, such as nuts, wrenches, and screwdrivers. This design not only improves tool management efficiency but also allows construction workers to quickly locate the required tools, thereby increasing construction efficiency. Furthermore, the toolbox can be equipped with locking mechanisms to prevent tools from falling out during movement, ensuring safe storage. This design not only enhances the flexibility of the scaffolding but also strengthens its functionality. The toolbox is particularly suitable for storing small tools such as nuts and wrenches, which are frequently used when adjusting the height of support plates. Because workers need to operate on ladders, disassembled nuts or bolts are easily overlooked or lost due to negligence. Therefore, the toolbox provides a reliable storage location for these tools, preventing loss or damage. The toolbox's position can be adjusted as needed. For example, when a worker needs to disassemble a nut, the toolbox can be moved closer to the work area via a slide rail for easy placement and retrieval. This design not only reduces the risk of tool loss but also improves construction convenience and efficiency, making the scaffolding more practical and reliable in actual use.

[0016] Preferably, the guide rail is provided with two mounting plates spaced apart, and the slide rail is threaded with a lead screw, the two ends of which are rotatably connected to the two mounting plates respectively.

[0017] In this technical solution, it's important to note that a lead screw is used to drive the slide rail, thereby adjusting the position of the toolbox on the slide rail. A lead screw is a common mechanical transmission component that converts rotary motion into linear motion, offering high precision and stability. In this solution, the lead screw can be rotated manually or electrically, depending on the specific application and requirements. Manual operation is typically suitable for small scaffolding or occasional adjustments, while electric operation is suitable for large scaffolding or scenarios requiring frequent adjustments. Both ends of the lead screw are fixed to the guide rail via mounting plates, ensuring stability during rotation. The slide rail and lead screw are threaded together; when the lead screw rotates, it moves the slide rail along the guide rail, thus achieving precise adjustment of the toolbox position. This design not only improves the flexibility of the scaffolding but also enhances its functionality, allowing the toolbox to be flexibly positioned according to the needs of construction workers, facilitating tool storage and retrieval.

[0018] Preferably, handwheels are fixedly connected to both ends of the lead screw through the mounting plate.

[0019] In this technical solution, it should be noted that the handwheel design allows the operator to manually rotate the handwheel to drive the lead screw, thereby moving the slide rail along the guide rail direction and achieving flexible adjustment of the toolbox position. The connection between the handwheel and the lead screw is usually achieved through a keyway or thread, ensuring that relative slippage does not occur during rotation.

[0020] Preferably, the support plate has several through holes.

[0021] In this technical solution, it should be noted that the through holes can serve as drainage holes, allowing water to drain from the support plates promptly in rainy or humid environments, preventing corrosion and damage to the scaffolding structure. In some special applications, the through holes can also be used as wiring channels, facilitating the passage of electrical wires or pipes, thus improving the scaffolding's versatility and adaptability. The size and distribution of the through holes can be designed according to actual needs to meet different construction and usage requirements.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0023] 1. This utility model, through the use of a screw, a first locking ring, a second locking ring, and a nut, has a simple structure and convenient operation, achieving the beneficial effect of easily and quickly adjusting the height of the support plate. The cooperation between the screw and the nut allows the locking ring to flexibly clamp or loosen the column.

[0024] 2. This utility model, through the ingenious design of the support rods, enhances the stability and load-bearing capacity of the scaffolding, thus providing a stable and reliable working platform for construction workers. The support rods are typically made of high-strength steel, such as Q235 or Q345B, forming a triangular support structure, which significantly improves the overall stability and lateral force resistance of the scaffolding, ensuring the safety of construction workers.

[0025] 3. In this utility model, by setting a groove on the side wall of the column to cooperate with the first and second locking rings, a stable support is provided for the locking rings, achieving the beneficial effect of preventing the locking rings from loosening and ensuring the reliability of the scaffold connection. The groove design ensures that the bottom of the locking ring is stably embedded therein, preventing safety accidents caused by loosening and effectively reducing safety risks during construction.

[0026] 4. In this utility model, by setting a washer between the nut and the mounting block, the washer has the functions of dispersing pressure, reducing wear, and preventing the nut from loosening, thus achieving the beneficial effects of extending the service life of the mounting block and the screw, and improving the stability of the scaffold connection. The washer also provides a certain amount of fine-tuning space, allowing for more precise control of the clamping force of the locking ring on the column when tightening the nut, ensuring the stability and safety of the scaffold.

[0027] 5. In this utility model, by setting guide rails, slide rails and tool boxes on the support plate, it has the function of convenient tool storage and retrieval, and achieves the beneficial effect of improving construction convenience and efficiency. Attached Figure Description

[0041] Example

[0042] like Figures 1-5As shown in the figure, this utility model discloses a height-adjustable scaffold, including a scaffold body 1. A support plate 3 is provided on the scaffold body 1, and the support plate 3 is mounted on four uprights 2 of the scaffold body 1. The support plate 3 is mounted on the uprights 2 via multiple connecting devices 6. Each connecting device 6 includes a first locking ring 9 and a second locking ring 10. One end of the first locking ring 9 and the second locking ring 10 are respectively hinged to the support plate 3 and form a ring structure with each other. The ends of the first locking ring 9 and the second locking ring 10 away from the support plate 3 are each provided with a mounting block 11. Each mounting block 11 has a socket, and a screw 12 is provided inside the socket. Two nuts 14 are screwed onto the screw 12, and the two nuts 14 are located on one side of each mounting block 11. It should be noted that the support plate 3 is used to support workers, ensuring their safety and stability during high-altitude operations. The support plate 3 is typically made of wood with a thickness of not less than 50mm or steel plate with a thickness of not less than 1.5mm to ensure sufficient strength and durability. The support plate 3 is installed on the four uprights 2 of the scaffold body 1, and is securely connected to the uprights 2 through multiple connecting devices 6. The connecting device 6 includes a first locking ring 9 and a second locking ring 10. One end of each locking ring is hinged to the support plate 3, and they can form a complete circular structure. This design not only provides sufficient support but also allows for easy opening when needed, enabling height adjustment. Ladders are installed on both sides of the scaffold, providing workers with a safe climbing path to easily reach the support plate 3 for work. When the height of the support plate 3 needs to be adjusted, workers can do so by tightening two nuts 14. These two nuts 14 are mounted on a screw rod 12 and move along the screw rod 12 by rotation. The design of the screw rod 12 allows for precise control of the movement of the nuts 14, which in turn drives the two locking rings to clamp or loosen the uprights 2. This adjustment mechanism is simple and efficient, ensuring the stability of the support plate 3 at different heights. In operation, firstly, the two nuts 14 are pulled, moving them away from each other, releasing the restraints on the two mounting blocks 11 and loosening the previously tight ring structure formed by the first locking ring 9 and the second locking ring 10. At this point, the worker can move the support plate 3 from its current position to the desired height. Once the desired height is reached, the worker needs to re-secure the support plate 3 to the column 2: firstly, the first locking ring 9 and the second locking ring 10 are rotated to the closed position, forming a complete ring structure that surrounds the column 2. Then, the two nuts 14 are pulled again, this time moving them closer together along the screw 12. As the nuts 14 gradually approach each other, they begin to apply pressure to the mounting blocks 11, forcing the first locking ring 9 and the second locking ring 10 to gradually tighten, ultimately clamping the column 2 securely.This process not only ensures the stability of support plate 3 at the new height position, but also guarantees the stability and safety of the entire scaffolding structure, providing a reliable working platform for workers. Through this ingenious design, scaffolding height adjustment becomes more convenient and efficient, greatly improving construction efficiency. This height-adjustable scaffolding meets the needs of different construction scenarios.

[0043] like Figure 3 As shown, in this embodiment, a washer 13 is provided between each nut 14 and the mounting block 11, and the washer 13 is sleeved on the screw 12. It should be noted that the washer 13 can evenly distribute the pressure of the nut 14 on the mounting block 11, preventing local deformation or damage caused by pressure concentration, thereby extending the service life of the mounting block 11 and the screw 12. The washer 13 can reduce the direct contact between the nut 14 and the mounting block 11, reducing the friction between them and preventing wear on the surface of the mounting block 11 when tightening or loosening the nut 14. The thickness of the washer 13 can provide a certain amount of fine-tuning space, allowing for more precise control of the clamping force of the locking ring on the column 2 when tightening the nut 14, ensuring the stability and safety of the scaffold. The washer 13 also plays a certain role in preventing loosening, preventing the nut 14 from loosening on its own under vibration or impact, thereby ensuring the reliability of the scaffold connection. Depending on actual needs, washer 13 of different thicknesses and materials can be selected to adapt to different construction environments and requirements, improving the versatility and flexibility of the scaffold.

[0044] like Figure 5 As shown, in this embodiment, the side wall of the column 2 is provided with a plurality of slots 19 that cooperate with the first locking ring 9 and the second locking ring 10. These slots 19 are spaced apart along the height direction of the column 2. It should be noted that the slots 19 are mainly used to provide stable support for the bottom of the locking rings. When the first locking ring 9 and the second locking ring 10 close to form a circular structure and clamp the column 2, the slots 19 ensure that the bottom of the locking ring is stably embedded therein, preventing the locking ring from loosening and causing a safety accident.

[0045] like Figure 2As shown in this embodiment, the support plate 3 is also provided with four support rods 5, each of which cooperates with the column 2. One end of each support rod 5 is connected to the column 2 via a connecting device 6, and the other end is connected to the support plate 3. It should be noted that the support rods 5 are typically made of high-strength steel, such as Q235 or Q345B, which has good bending and shear resistance, effectively distributing the weight of the support plate 3 and the pressure generated by workers during operation, thereby reducing the burden on the support plate 3. The support rods 5, the column 2, and the support plate 3 form a triangular support structure. This structural design significantly improves the overall stability and load-bearing capacity of the scaffolding. Due to its geometric stability, the triangular structure can effectively resist lateral and vertical forces, reducing swaying and deformation of the scaffolding during use. Furthermore, the cross-sectional shape of the support rods 5 is typically a combination of double angle steel, double channel steel, H-shaped section, or box-shaped section. These cross-sectional shapes provide high lateral stiffness and compressive strength, ensuring that the support rods 5 remain stable even under large loads. With the auxiliary support of support rod 5, the entire scaffold structure is more stable, providing construction workers with a safe and reliable working platform. This design not only improves the stability and safety of the scaffold but also makes it better adaptable to various complex construction scenarios.

[0046] like Figure 4As shown, in this embodiment, the support plate 3 has guide rails 7 at both ends along its length. A slide rail 15 is slidably connected to the guide rail 7, and a tool box 8 is mounted on the slide rail 15. It should be noted that the guide rails 7 are typically made of high-strength steel, such as Q235 or Q345B, to ensure their load-bearing capacity and durability. This material choice not only supports the weight of the tool box 8 and its internal tools but also ensures the stability and wear resistance of the guide rails 7 during frequent use. The tool box 8 is designed with practicality and safety in mind, typically using lightweight yet sturdy materials such as aluminum alloy or engineering plastics to reduce overall weight while providing sufficient protection to prevent damage to tools during use. The tool box 8 can have multiple compartments inside for storing different tools, such as nuts 14, wrenches, screwdrivers, etc. This design not only improves tool management efficiency but also allows construction workers to quickly find the tools they need, thereby improving construction efficiency. Furthermore, the tool box 8 can be equipped with a locking device to prevent tools from falling out during movement, ensuring safe storage of the tools. This design not only improves the flexibility of the scaffolding but also enhances its functionality. The toolbox 8 is specifically designed for storing small tools such as nuts 14 and wrenches, which are frequently used when adjusting the height of the support plate 3. Since workers need to operate on ladders, disassembled nuts 14 or bolts 12 are easily overlooked or lost due to negligence. Therefore, the toolbox 8 provides a reliable storage location for these tools, preventing loss or damage. The position of the toolbox 8 can be adjusted as needed. For example, when a worker needs to disassemble a nut 14, the toolbox 8 can be moved closer to the operating position via the slide rail 15 for easy placement and retrieval of the nut 14. This design not only reduces the risk of tool loss but also improves the convenience and efficiency of construction, making the scaffolding more practical and reliable in actual use.

[0047] like Figure 4As shown, in this embodiment, two mounting plates 17 are spaced apart on the guide rail 7, and a lead screw 16 is threadedly connected to the slide rail 15. The two ends of the lead screw 16 are rotatably connected to the two mounting plates 17 respectively. It should be noted that the lead screw drives the slide rail 15 to move, thereby adjusting the position of the toolbox 8 on the slide rail 15. The lead screw is a common mechanical transmission component that can convert rotational motion into linear motion, possessing high precision and stability. In this solution, the rotation of the lead screw can be achieved manually or electrically, depending on the actual application scenario and requirements. Manual operation is typically suitable for small scaffolding or occasional adjustments, while electric operation is suitable for large scaffolding or scenarios requiring frequent adjustments. The two ends of the lead screw are fixed to the guide rail 7 by the mounting plates 17, ensuring the stability of the lead screw during rotation. The slide rail 15 is threadedly engaged with the lead screw; when the lead screw rotates, it drives the slide rail 15 to move along the direction of the guide rail 7, thereby achieving precise adjustment of the toolbox 8's position. This design not only improves the flexibility of the scaffolding but also enhances its functionality, allowing the toolbox 8 to be flexibly positioned according to the needs of construction workers, facilitating the storage and retrieval of tools.

[0048] like Figure 4 As shown, in this embodiment, handwheels 18 are fixedly connected to both ends of the lead screw 16 through the mounting plate 17. It should be noted that this design of the handwheels 18 allows the operator to manually rotate the handwheels 18 to drive the lead screw 16 to rotate, thereby moving the slide rail 15 along the guide rail 7, achieving flexible adjustment of the toolbox 8 position. The connection between the handwheels 18 and the lead screw 16 is typically achieved through a keyway or thread, ensuring that relative slippage does not occur during rotation.

[0049] like Figure 2 As shown, in this embodiment, the support plate 3 is provided with several through holes 4. It should be noted that the through holes 4 can serve as drainage holes, allowing water to drain from the support plate 3 in rainy or humid environments, preventing corrosion and damage to the scaffolding structure. In some special applications, the through holes 4 can also be used as wiring channels, facilitating the passage of wires or pipes, thus improving the versatility and adaptability of the scaffolding. The size and distribution of the through holes 4 can be designed according to actual needs to meet different construction and usage requirements.

[0050] The working principle of this utility model is as follows:

[0051] When adjusting the scaffolding height, construction workers first climb the ladder, place the toolbox 8 on the slide rail 15, and move it to an easily accessible position to store tools such as nuts 14 and wrenches, preventing loss or damage during adjustment. Next, the workers rotate nut 14 to loosen the locking rings (the process is done step-by-step or simultaneously by multiple workers if there are multiple locking rings). At this point, the circular structure formed by the first locking ring 9 and the second locking ring 10 loosens, allowing the workers to move the support plate 3 to the desired height. Once the designated height is reached, the workers rotate the first locking ring 9 and the second locking ring 10 to a closed state, forming a complete circular structure that surrounds the column 2. Then, the nut 14 is rotated again, bringing it closer together along the screw 12 until the locking rings firmly clamp the column 2, ensuring the stability of the support plate 3 at the new height. Throughout the adjustment process, the toolbox 8 remains nearby for easy access to tools.
