Description

Technical Field

[0001] This application relates to the field of photovoltaic power generation equipment installation and maintenance, and in particular to sliding auxiliary supports. Background Technology

[0002] The scale of photovoltaic power plant construction continues to expand, with applications including ground-mounted centralized power plants, rooftop distributed power plants, fish-solar hybrid systems, and agricultural-solar hybrid systems. Against this backdrop, the demand for on-site installation and subsequent operation and maintenance of photovoltaic modules has surged. However, current mainstream construction methods still rely on traditional A-frame ladders, scaffolding, or fixed construction platforms, which present numerous technical challenges.

[0003] Uneven ground can easily lead to instability of the supporting structure, posing a high risk to workers working at heights and thus highlighting safety hazards. Specifically, traditional supporting structures such as A-frame ladders and scaffolding are prone to tilting or slipping on uneven ground, causing workers to fall or components to fall, resulting in significant safety hazards and insufficient safety.

[0004] Fixed construction platforms and some traditional support structures suffer from problems such as heavy equipment making transportation difficult, cumbersome assembly and disassembly requiring multiple people for disassembly and transportation, and high labor costs. Furthermore, the difficulty in fixing and adjusting the structure limits the working space, reduces construction efficiency, and results in poor flexibility, making it difficult to adapt to the rapid deployment needs of distributed power stations or complex terrain areas. They also suffer from insufficient portability and lightweighting. Moreover, traditional fixed structures cannot be flexibly moved with the work site, leading to low work efficiency.

[0005] Photovoltaic modules are typically heavy, ranging from tens to hundreds of kilograms. Traditional support structures lack specialized designs for sliding and positioning photovoltaic modules, relying solely on manual dragging and handling, which can easily cause damage to the modules. The high frictional resistance can also damage the module frames or glass surfaces.

[0006] Currently, there are no lightweight, modular, and mobile auxiliary tools on the market specifically designed for the disassembly and assembly of photovoltaic modules. If large general-purpose lifting platforms or hoisting equipment are used, there are problems such as bulky equipment, poor flexibility, high cost, and complicated operation, which are not suitable for distributed or small and medium-sized power plants with complex terrain. Utility Model Content

[0007] Therefore, it is necessary to provide a sliding auxiliary support.

[0008] One embodiment of this application is a sliding auxiliary support, which includes a first overlapping end, a second abutting end, a main support, and a pulley assembly;

[0009] The first overlapping end and the second abutting end are respectively disposed at both ends of the main support. One of the first overlapping end and the second abutting end is configured as a free end, and the other is configured to be connected to the external structure, so that the sliding auxiliary support and the external structure are in one of the overlapping state and the abutting state.

[0010] The pulley assembly is mounted on the main support, and the pulley assembly is higher than the first overlapping end and the second abutting end in the direction of gravity;

[0011] The pulley assembly is configured to receive the transported item and is connected to the item in a rolling support, so that the item is movably mounted on the pulley assembly.

[0012] The aforementioned sliding auxiliary support, through its cooperating first overlapping end, second abutting end, main support, and pulley assembly, can be applied to the auxiliary installation and removal of photovoltaic modules in photovoltaic power plant operations. On one hand, it boasts advantages such as simple structure, safety and reliability, strong adaptability, and portability, allowing for easy carrying by a single worker even in complex terrain environments. This eliminates the need for multiple-person lifting operations, enabling a single person to move and position the modules, thus improving work efficiency and making it suitable for complex maintenance environments such as photovoltaic power plant operation and maintenance. On the other hand, it is suitable for lifting, unloading, or moving heavy structural components, applicable in complex terrains such as mountains, rooftops, and water surfaces, or in high-altitude work scenarios. This significantly reduces the physical exertion of workers, lowers the risk of falls from heights and component impact injuries, and significantly improves operational safety, thereby facilitating the safe and efficient installation, replacement, or disassembly of structural components. Furthermore, by replacing the traditional dragging method with rolling conveying, it avoids edge scratches or surface cracks on structural components during movement, effectively reducing the damage rate during transport, making it particularly suitable for the installation and maintenance of photovoltaic modules.

[0017] In some embodiments, the sliding auxiliary support further includes an adjusting rod connected to the main support for adjusting the overall length of the sliding auxiliary support.

[0018] In some embodiments, the main support includes a first part and a second part that are separately disposed, wherein the first overlapping end is connected to the first part and the second abutting end is connected to the second part;

[0019] The adjusting rod includes a rod body and a locking member connected to each other. The rod body is connected to the first part and the second part respectively, so as to adjust the overall length of the sliding auxiliary support by adjusting the relative distance between the first part and the second part.

[0020] The locking member is used to release the rod in the open state so that the rod can move to adjust the relative distance between the first part and the second part, and to fix the rod in the locked state to maintain the overall length of the sliding auxiliary bracket.

[0021] In some embodiments, the pulley assembly includes a mounting base, a roller, and a pulley;

[0022] The mounting base is disposed on the main support, and the pulley is mounted on the mounting base via the roller. The pulley is configured to receive the item to be transported, and the pulley rolls relative to the mounting base while the item to be transported moves on the pulley.

[0023] In some embodiments, the number of pulley assemblies is at least two, and the distance between at least one pulley assembly and the first overlapping end is no greater than 10 cm, and the distance between the other pulley assembly and the second abutting end is no greater than 10 cm.

[0024] In some embodiments, the main support includes a first rod and a second rod arranged side by side, the first rod and the second rod forming a single integral structure;

[0025] The first overlapping end and the second abutting end are respectively disposed at both ends of the integral structure. The first overlapping end is respectively connected to the first rod body and the second rod body, and the second abutting end is respectively connected to the first rod body and the second rod body.

[0026] The pulley assembly is mounted on the overall structure and is connected to the first rod body and the second rod body respectively.

[0027] In some embodiments, the extension direction of the first shaft is parallel to the extension direction of the second shaft; or,

[0028] The main support also includes a reinforcing rod, which connects the first rod body and the second rod body. Attached Figure Description

[0046] This application discloses a sliding auxiliary support, which includes some or all of the technical features of the following embodiments; that is, the sliding auxiliary support includes some or all of the following structures. In one embodiment of this application, a sliding auxiliary support includes a first overlapping end, a second abutting end, a main support, and a pulley assembly; the first overlapping end and the second abutting end are respectively disposed at both ends of the main support, one of the first overlapping end and the second abutting end is configured as a free end, and the other is configured to be connected to an external structure, so that the sliding auxiliary support is in one of an overlapping state and an abutting state with the external structure; the pulley assembly is disposed on the main support, and the pulley assembly is higher than the first overlapping end and the second abutting end in the height direction; the pulley assembly is configured to support the transported item and to be rolled and supportedly connected to the item to be transported, so that the item to be transported is movably disposed on the pulley assembly. The aforementioned sliding auxiliary support, through its cooperating first overlapping end, second abutting end, main support, and pulley assembly, can be applied to the auxiliary installation and removal of photovoltaic modules in photovoltaic power plant operations. On the one hand, it boasts advantages such as simple structure, safety and reliability, strong adaptability, and portability, allowing for single-person use even in complex terrain environments. This changes the multi-person lifting operation mode, enabling a single person to complete module movement and positioning, thus improving work efficiency and making it suitable for complex maintenance environments such as photovoltaic power plant operation and maintenance. On the other hand, it is suitable for lifting, unloading, or moving heavy structural components, applicable in complex terrains such as mountains, rooftops, and water surfaces, or in high-altitude operation scenarios. This significantly reduces the physical exertion of workers, lowers the risk of falls from heights and component impact injuries, and significantly improves operational safety, thereby facilitating the safe and efficient installation, replacement, or disassembly of structural components. Furthermore, by replacing the traditional dragging method with rolling conveying, it avoids frame scratches or surface cracks on structural components during movement, effectively reducing the damage rate during movement, especially suitable for the installation and maintenance of photovoltaic modules. The following section will combine... Figures 1 to 10 The sliding auxiliary support will be described in detail.

[0047] In some embodiments, a sliding auxiliary support 700, such as Figure 1As shown, it includes a first overlapping end 100, a second abutting end 200, a main support 300, and a pulley assembly 400; the first overlapping end 100 and the second abutting end 200 are respectively disposed at both ends of the main support 300, and combined with... Figure 3 and Figure 4 One of the first overlapping end 100 and the second abutting end 200 is configured as a free end, and the other is configured to be connected to the external structure 910, so that the sliding auxiliary support 700 is in either an overlapping state or an abutting state with the external structure 910; the pulley assembly 400 is disposed on the main support 300, and the pulley assembly 400 is higher than the first overlapping end 100 and the second abutting end 200 in the gravity direction 800; combined with Figure 2 The pulley assembly 400 is configured to receive the transported item 900 and to be connected to the transported item 900 in a rolling support connection, so that the transported item 900 is movably disposed on the pulley assembly 400.

[0048] This structural design, through the matching first overlapping end 100, second abutting end 200, main support 300, and pulley assembly 400, can be applied to the auxiliary installation and removal of photovoltaic modules in photovoltaic power plant operations. On the one hand, it boasts advantages such as simple structure, safety and reliability, strong adaptability, and portability, allowing workers to carry it alone even in complex terrain environments. This changes the multi-person lifting operation mode, enabling a single person to complete module movement and positioning, thus improving work efficiency and making it suitable for maintenance in complex environments such as photovoltaic power plant operation and maintenance. On the other hand, it is suitable for lifting, unloading, or moving heavy structural components, applicable in complex terrains such as mountains, rooftops, and water surfaces, or in high-altitude operation scenarios. This greatly reduces the physical exertion of workers, lowers the risk of falls from heights and component impact injuries, and significantly improves operational safety, thereby facilitating the safe and efficient installation, replacement, or disassembly of structural components. Furthermore, the use of rolling conveyor instead of traditional dragging avoids edge scratches or surface cracks on structural components during movement, effectively reducing the damage rate during movement, making it particularly suitable for the installation and maintenance of photovoltaic modules.

[0049] To facilitate the manufacturing of the sliding auxiliary support 700, in some embodiments, the first overlapping end 100, the second abutting end 200, and the main support 300 are integrally formed. Alternatively, in other embodiments, the first overlapping end 100 and the second abutting end 200 are respectively inserted into or screwed onto the main support 300. In some embodiments, such as... Figure 2As shown, when the sliding auxiliary support 700 is in a working state, the height of the first overlapping end 100 and the height of the second abutting end 200 are level in the gravity direction 800. At this time, the photovoltaic cell assembly to be transported, such as 50 kg or other weight, can be easily pushed to the installation position, such as the roof, through the sliding auxiliary support 700.

[0050] This design, on the one hand, integrates the first overlapping end 100, the second abutting end 200, and the main support 300, reducing assembly steps, minimizing assembly errors, and improving the overall structural stability and production efficiency of the sliding auxiliary support 700. The plug-in or screw-in connection method facilitates individual component processing, transportation, and subsequent maintenance and replacement, reducing production and after-sales costs and adapting to different production scales. On the other hand, when the sliding auxiliary support 700 is in a working state where the first overlapping end 100 and the second abutting end 200 are at the same height in the gravity direction 800, it eliminates the height difference obstacle to the movement of the component 900. Even for photovoltaic cell modules weighing 50 kg or more, a single worker can easily push them to the roof or other installation locations without the need for multiple people to work together, further simplifying the operation process. Meanwhile, the rolling support of the pulley assembly 400 can not only prevent the photovoltaic cell module from being scratched on the frame or cracked on the surface during the pushing process, thus ensuring the integrity of the module, but also greatly reduce the physical exertion of the workers and reduce the risk of modules falling and personnel injury during high-altitude operations. It is especially suitable for photovoltaic module installation operations in complex scenarios such as rooftops, taking into account both safety and efficiency.

[0051] Depending on the type of external structure 910, such as a planar structure or other external structure 910 with an abutment position, a second abutment end 200 may be selected to connect the external structure 910. In some embodiments, such as... Figure 3 As shown, in the state of being connected to the external structure 910, the second abutting end 200 is configured to abut against the external structure 910. In this state, the first overlapping end 100 is configured as a free end, that is, not connected to the external structure 910. At this time, in the direction of gravity 800, the first overlapping end 100 is lower than the second abutting end 200. In use, the item to be transported 900 is first placed on it, and the first overlapping end 100 is slowly lifted upward until the height of the first overlapping end 100 and the second abutting end 200 is similar or level. The item to be transported 900 is then pushed towards the second abutting end 200, at which time the pulley assembly 400 rolls. In this embodiment, the second abutting end 200 has an L-shaped abutting structure.

[0052] This design offers several advantages. First, it allows for flexible connection of the second abutment end 200 to planar or other external structures 910 with abutment points. The L-shaped abutment structure, in particular, ensures a stable fit with the external structure 910, preventing displacement of the sliding auxiliary support 700 during operation. This adapts to the connection needs of different external structures 910 shapes, solving the problem of unstable connection between the support and the external structure 910 in complex scenarios, further expanding the applicability of the sliding auxiliary support 700. Second, in the initial state, the first overlapping end 100 is lower than the second abutment end 200 in the direction of gravity 800, making it easier to position the transported item 900 and reducing the risk of slippage during placement. By slowly lifting the first overlapping end 100 to a height similar to or equal to the second abutment end 200, the height difference can be smoothly eliminated, preventing impact from sudden height changes on the transported item 900. Combined with the rolling support of the pulley assembly 400, pushing the transported item 900 towards the second abutment end 200 requires less effort and can be operated by a single person without the need for multiple people to lift and assist.

[0053] Depending on the type of external structure 910, such as a rod-shaped or other external structure 910 with overlapping positions, a first overlapping end 100 can be selected to connect the external structure 910. In some embodiments, such as... Figure 4 As shown, in the state of being connected to the external structure 910, the first overlapping end 100 is configured to overlap with the external structure 910 in a semi-enclosed manner; similarly, in this state, the second abutting end 200 is configured as a free end, that is, not connected to the external structure 910. At this time, in the gravity direction 800, the second abutting end 200 is lower than the first overlapping end 100. In use, the item to be transported 900 is first placed on it, and the second abutting end 200 is slowly pushed upward until the height of the second abutting end 200 is close to or level with the height of the first overlapping end 100. The item to be transported 900 is then pushed towards the first overlapping end 100, at which time the pulley assembly 400 rolls. In this embodiment, the first overlapping end 100 has a U-shaped overlapping structure. In some embodiments, the first overlapping end 100 has a U-shaped overlapping structure, and the second abutting end 200 has an L-shaped abutting structure.

[0054] This design serves several purposes. First, for rod-shaped or other external structures 910 with overlapping joints, the first overlapping end 100 is used to connect in a semi-enclosed manner. In particular, its U-shaped overlapping structure can form a wrap-around fit with the rod-shaped external structure 910, greatly improving connection stability and preventing the sliding auxiliary support 700 from shifting axially or radially along the external structure 910 during operation. Second, the combination of the U-shaped structure of the first overlapping end 100 and the L-shaped structure of the second abutment end 200 can be adapted to different external structures 910 with overlapping or abutment joints, achieving multi-purpose use without the need to equip different external structures 910 with separate supports. This significantly enhances the applicability of the sliding auxiliary support 700 in complex scenarios such as rod-shaped supports in mountain photovoltaic power stations and rod-shaped load-bearing components on roofs. On the other hand, in the initial state, the second abutment end 200 is lower than the first overlapping end 100 in the direction of gravity 800. When the transport item 900 is placed, it can rely on the lower second abutment end 200 to form initial support, reducing the risk of imbalance and slippage during placement. By slowly lifting the second abutment end 200 to a height similar to or level with the first overlapping end 100, the height difference can be smoothly transitioned, avoiding collisions or impacts to the transport item 900 due to sudden height changes. With the rolling support of the pulley assembly 400, the resistance is greatly reduced when pushing the transport item 900 towards the first overlapping end 100. The operation can be completed by a single person without the need for multiple people to lift it, which reduces the physical exertion of the staff and avoids the risk of asynchronous actions when multiple people are working together.

[0055] For ease of assembly and use, in some embodiments, such as Figure 1 and Figure 5 As shown, the pulley assembly 400 includes a mounting base 401, a roller 402, and a pulley 403. The mounting base 401 is disposed on the main support 300, and the pulley 403 is mounted on the mounting base 401 via the roller 402. The pulley 403 is configured to receive the item to be transported 900, and when the item to be transported 900 moves on the pulley 403, the pulley 403 rolls relative to the mounting base 401 to convert the sliding friction of the item to be transported 900 into the rolling friction of the pulley 403, so that the user can work easily while protecting the item to be transported 900.

[0056] This design, on the one hand, disassembles the pulley assembly 400 into a modular structure consisting of a mounting base 401, a roller 402, and a pulley 403. Each component can be manufactured separately, reducing manufacturing precision requirements and production difficulty. During assembly, it is only necessary to install the pulley 403 onto the mounting base 401 via the roller 402, and then fix the mounting base 401 to the main bracket 300. The operation is simple and convenient, greatly improving assembly efficiency. If the pulley 403 or roller 402 wears out in the future, the damaged component can be disassembled and replaced separately without replacing the entire pulley assembly 400. This significantly reduces maintenance costs and resource waste, and extends the overall service life of the sliding auxiliary bracket 700. On the other hand, through the cooperation of roller 402 and pulley 403, the sliding friction force of the component 900 to be transported can be converted into the rolling friction force of pulley 403. Since the rolling friction force is much smaller than the sliding friction force, the staff can push the component 900 to be transported without applying excessive pushing force. Even when facing structural components such as photovoltaic modules that are heavy, a single person can easily complete the movement operation, greatly reducing physical exertion and avoiding operational errors caused by excessive force. At the same time, the elimination of sliding friction can effectively reduce frictional damage between the bottom of the component 900 to be transported and the bracket, especially avoiding problems such as frame scratches and surface cracks in precision structural components such as photovoltaic modules, ensuring the integrity of the component 900 to be transported, and further adapting to the safe and efficient transportation needs of structural components in scenarios such as photovoltaic power stations.

[0057] To facilitate support under stress, in some embodiments, such as Figure 2 As shown, the number of pulley assemblies 400 is at least two; in some embodiments, the number of pulley assemblies 400 is at least two, and the distance between at least one pulley assembly 400 and the first overlapping end 100 is no greater than 10 cm, and the distance between the other pulley assembly 400 and the second abutting end 200 is no greater than 10 cm. Figure 2 In the illustrated embodiment, there are two pulley assemblies 400, including a first pulley 410 and a second pulley 420. The first pulley 410 is located near the first overlapping end 100, and the second pulley 420 is located near the second abutting end 200. For example, the distance between the first pulley 410 and the first overlapping end 100 is no greater than 10 cm; similarly, the distance between the second pulley 420 and the second abutting end 200 is no greater than 10 cm. For a longer sliding auxiliary support 700, as an example, the number of pulley assemblies 400 may be three or four.

[0058] This design, on the one hand, sets at least two pulley assemblies 400, which can provide multi-point support for the transported item 900 placed on them, preventing the transported item 900 from tilting and slipping due to a shift in the center of gravity caused by single-point support. Especially for long and heavy structural components such as photovoltaic modules, it can effectively distribute their weight load, reduce the stress on a single pulley assembly 400, reduce deformation or damage to components due to overload, and extend the service life of the sliding auxiliary support 700. On the other hand, the layout of at least one pulley assembly 400 being no more than 10 cm away from the first overlapping end 100 and the other being no more than 10 cm away from the second abutting end 200 allows the support points to cover both ends of the main support 300, further optimizing the force distribution and preventing the transported item 900 from sagging or bumping during movement due to a lack of support at both ends. On the other hand, taking the configuration of two pulley assemblies 400 respectively close to the first overlapping end 100 and the second abutting end 200 as an example, it can not only meet the support requirements of the main support 300 of conventional length, but also ensure that the item to be transported 900 is always within the support range of the pulley assembly 400 during its entire movement from the first overlapping end 100 to the second abutting end 200, thus avoiding loss of support and falling off midway; or vice versa. Furthermore, for the longer sliding auxiliary support 700, the number of pulley assemblies 400 can be increased to three or four. The support points can be evenly distributed according to the length of the main support 300 to adapt to the transfer needs of longer items to be transported 900, while maintaining a continuous rolling conveying mode, which reduces the pushing resistance of the workers and avoids the item to be transported 900 from malfunctioning due to insufficient support.

[0059] To further reduce the weight of the main support 300 for easier carrying, in some embodiments, such as Figure 6 As shown, the main support 300 includes a first rod 310 and a second rod 320 arranged side by side, forming a single integral structure. A first overlapping end 100 and a second abutting end 200 are respectively disposed at both ends of the integral structure. The first overlapping end 100 connects to both the first rod 310 and the second rod 320, and the second abutting end 200 connects to both the first rod 310 and the second rod 320. The pulley assembly 400 is disposed on the integral structure and connects to both the first rod 310 and the second rod 320. In this embodiment, the extension direction of the first rod 310 is parallel to the extension direction of the second rod 320.

[0060] This design, on the one hand, uses the first pole 310 and the second pole 320 arranged side by side to form an integral structure. Compared with traditional solid or single-pole main supports, it significantly reduces the amount of material used while ensuring basic support performance, directly reducing the weight of the main support 300 and even the entire sliding auxiliary support 700. The lightweight design allows workers to easily carry the equipment by a single person when operating in complex terrains such as mountains and rooftops in photovoltaic power stations, without the need for additional manpower to assist in carrying it. This solves the problems of inconvenience and labor-intensive carrying of traditional heavy supports, further meeting the operational needs of complex outdoor scenarios and improving the flexibility of equipment use. On the other hand, the first pole body 310 and the second pole body 320 extend parallel to each other and form an integral structure. With the first overlapping end 100 and the second abutting end 200 connected to the two pole bodies respectively, the external force can be evenly distributed to the two pole bodies, avoiding bending or breakage caused by concentrated force on a single pole. At the same time, the pulley assembly 400 connects the first pole body 310 and the second pole body 320 respectively, so that the weight load of the component to be transported 900 is transferred to the double pole structure through the pulley assembly 400, further increasing the load-bearing capacity of the main support 300. Even when faced with heavy components to be transported such as photovoltaic cell components weighing 50 kg or more, the structure can remain stable and not deform. On the other hand, the symmetrical structure of the double poles makes the overall center of gravity of the main support 300 more balanced. When the sliding auxiliary support 700 overlaps or abuts the external structure 910, it is not easy to tip over due to the shift of the center of gravity. Moreover, the parallel extension pole design can form a stable rolling support track with the pulley assembly 400, ensuring that the item to be transported 900 always slides smoothly in the preset direction during the movement, avoiding problems such as deviation and jamming.

[0061] To increase the structural strength of the main support 300 to accommodate the relatively heavier transported item 900, in some embodiments, such as Figure 7 As shown, the main support 300 also includes a reinforcing rod 330, which is connected between the first rod body 310 and the second rod body 320. Figure 7 In the illustrated embodiment, there are at least two reinforcing rods 330, and the extension direction of each reinforcing rod 330 is perpendicular to the extension direction of the first rod body 310 and the extension direction of the second rod body 320, respectively.

[0062] This design, on the one hand, connects the first pole body 310 and the second pole body 320 via reinforcing rods 330, effectively enhancing the overall integrity of the dual-pole structure and preventing relative offset or deformation of the two pole bodies when bearing the weight of the component 900 to be transported. In particular, the arrangement of at least two reinforcing rods 330 perpendicular to the extension direction of the pole bodies forms a stable "frame-like" support structure, significantly improving the bending and torsional resistance of the main support 300, enabling it to accommodate heavier components 900 to be transported, such as ultra-heavy photovoltaic modules or other heavy structural components, and preventing damage to the main support 300 due to excessive load. On the other hand, the increased structural strength makes the main support 300 more stable when bearing heavy objects, less prone to swaying or deformation, ensuring that the component 900 to be transported remains stable when moving on the pulley assembly 400, reducing the risk of the component 900 slipping or bumping due to instability of the support. At the same time, the stable support structure also reduces safety hazards for operators, allowing even heavy components to be transported safely and efficiently by a single person, further expanding the applicability of the sliding auxiliary support 700 in heavy-load scenarios.

[0063] To accommodate transported items 900 of varying lengths, in some embodiments, such as Figure 8 As shown, the sliding auxiliary support 700 also includes an adjusting rod 500, which is connected to the main support 300 and is used to adjust the overall length of the sliding auxiliary support 700. In some embodiments, the main support 300 includes a first portion 301 and a second portion 302 that are separately disposed, the first overlapping end 100 being connected to the first portion 301 and the second abutting end 200 being connected to the second portion 302; the adjusting rod 500 includes a rod body 510 and a locking member 520 connected to each other, the rod body 510 being connected to the first portion 301 and the second portion 302 respectively, so as to adjust the overall length of the sliding auxiliary support 700 by adjusting the relative distance between the first portion 301 and the second portion 302; the locking member 520 is used to release the rod body 510 in the open state so that the rod body 510 can move to adjust the relative distance between the first portion 301 and the second portion 302, and in the locked state to fix the rod body 510 to maintain the overall length of the sliding auxiliary support 700. As an example, the rod 510 is fixedly connected to the first part 301 and the second part 302 respectively, and the relative distance between the first part 301 and the second part 302 is adjusted by adjusting the length of the rod 510 itself.

[0064] This design allows for flexible adjustment of the overall length of the sliding auxiliary support 700 through the cooperation of the adjusting rod 500 and the main support 300. This enables it to accommodate different lengths of the components 900 to be transported—whether they are short, small photovoltaic accessories, long, standard photovoltaic modules, or ultra-wide structural components. There is no need to replace the support with different specifications; the support requirements can be met simply by adjustment. This avoids the problem of unstable support caused by the mismatch between the length of the component 900 and the support, significantly expanding the applicability of the sliding auxiliary support 700, especially suitable for the installation and maintenance of multi-specification components in photovoltaic power plants. On the other hand, the main support 300 is divided into two separate parts, the first part 301 and the second part 302. With the adjustment rod 500's rod body 510 and locking member 520, during adjustment, only the locking member 520 needs to be switched to the open state. The overall length of the support can be changed by adjusting the relative distance between the first part 301 and the second part 302 or the length of the rod body 510 itself. After adjustment, the locking member 520 is switched to the locked state to fix the length and maintain structural stability. The operation is simple and convenient, without the need for complicated tools. A single worker can complete the adjustment, which greatly improves work efficiency. At the same time, in the non-working state, the length of the support can be adjusted to the shortest, reducing storage space and making it easier to carry and transport, further meeting the mobile operation needs in complex scenarios such as mountains and rooftops. On the other hand, the locking member 520 can firmly fix the rod 510 in the locked state, so as to prevent the support from failing due to unexpected changes in length when the bracket is carrying the item to be transported 900, and ensure that the item to be transported 900 is always within the stable support range; and no matter what length it is adjusted to, the support function of the first overlapping end 100 and the second abutting end 200 is not affected.

[0065] As an example, the rod 510 is connected to one of the first portion 301 and the second portion 302, and is slidably connected to the other. As an example, the locking member 520 is used to release the rod 510 in the open state to allow the rod 510 to slide, and to fix the rod 510 in the locked state to maintain the overall length of the sliding auxiliary support 700. In some embodiments, such as... Figure 8As shown, the connection between the rod 510 and the first part 301 can also be described as the rod 510 being fixed to the first part 301, and the rod 510 being slidably connected to the second part 302. In the sliding state of the rod 510 relative to the second part 302, the distance between the second part 302 and the first part 301 changes. That is, by adjusting the relative distance between the first part 301 and the second part 302, the overall length of the sliding auxiliary support 700 is adjusted, thus changing the overall length of the sliding auxiliary support 700 to accommodate various lengths of the transported items 900. This design allows the rod 510 to be partially slidably connected to the main support 300, and, in conjunction with the locking member 520, the length of the sliding auxiliary support 700 can be flexibly adjusted to accommodate different transported items 900.

[0066] To facilitate carrying the sliding auxiliary support 700, as an example, such as Figure 9 As shown, the main support 300 includes a first part 301 and a second part 302 that are separately disposed. The first overlapping end 100 is connected to the first part 301, and the second abutting end 200 is connected to the second part 302. The adjusting rod 500 includes a rod body 510 connected to each other and two locking members 520. The rod body 510 is slidably connected to the first part 301 and slidably connected to the second part 302. Moreover, the rod body 510 is detachable from the first part 301 and the second part 302. The rod body 510 is connected to the first part 301 through one of the locking members 520. When the locking member 520 is in the open state, the rod body 510 can be detached from the first part 301 to shorten the overall length of the sliding auxiliary support 700 for easy carrying; or it can be installed and slid along the first part 301. The rod 510 is connected to the second part 302 via another locking member 520. When the locking member 520 is in the open state, the rod 510 can be detached from the second part 302 to shorten the overall length of the sliding auxiliary bracket 700 for easier carrying; or it can be attached and slid along the second part 302. Alternatively, when both locking members 520 are in the open state, the rod 510 can be detached from the first part 301 and the second part 302 respectively for easy carrying; or it can be attached and slid along the first part 301 and the second part 302 to adjust the relative distance between the first part 301 and the second part 302, thereby adjusting the overall length of the sliding auxiliary bracket 700.

[0067] This design, on the one hand, splits the main support 300 into two separate parts, the first part 301 and the second part 302. The rod 510 of the adjusting rod 500 is both slidably connected to and detachable from the two parts. With the help of two independent locking parts 520, the locking parts 520 can be opened when not in operation, and the rod 510 can be completely disassembled from the first part 301 and the second part 302. This makes the sliding auxiliary support 700 disassembled into three independent parts: the first part 301, the second part 302, and the rod 510, which greatly reduces the storage volume. Even if it is not completely disassembled, the overall length of the support can be shortened by sliding the rod 510. When carrying it in complex scenarios such as mountains and rooftops, workers do not need to carry an excessively long support. It can be easily carried by a single person, solving the problems of inconvenience and large space occupation of traditional integrated supports. On the other hand, it has significant advantages in terms of length adjustment flexibility and scene adaptability. During operation, opening the locking device 520 allows the rod 510 to slide along the first part 301 and the second part 302, flexibly adjusting the relative distance between the two parts, thereby changing the overall length of the sliding auxiliary support 700. This can accommodate both short-sized small photovoltaic accessories and meet the support requirements of long-sized photovoltaic modules, eliminating the need for separate supports for different specifications of the transported items 900. Furthermore, the two locking devices 520 are independently controlled, allowing for individual adjustment of the connection status on one side according to actual needs, making operation more flexible and further expanding the applicability of the support in various photovoltaic power plant operation scenarios. Moreover, when locked, the locking device 520 can firmly fix the connection between the rod 510 and the main support 300, preventing the support from sliding or separating when carrying the transported items 900, ensuring stable support.

[0068] To facilitate the installation or disassembly of relatively heavy transportable components 900, in some embodiments, such as Figure 10 As shown, the sliding auxiliary support 700 also includes a lifting member 600, which is detachably connected to one of the first overlapping end 100 and the second abutting end 200 to raise the height of the connected part under stress. For example, in one usage state, the first overlapping end 100 is connected to the external structure 910, and the lifting member 600 is detachably connected to the second abutting end 200, which is not connected to the external structure 910. After the item to be transported 900 is placed on the sliding auxiliary support 700, for example, on the pulley assembly 400, force is applied to the lifting member 600 to raise the height of the second abutting end 200 until the height of the second abutting end 200 is close to or level with the height of the first overlapping end 100. Conversely, the usage method where the second abutting end 200 is connected to the external structure 910 is similar and will not be elaborated further. For example, the lifting member 600 is a screw-driven height adjustment component or a gas spring structure, etc.

[0069] This design addresses the issue of particularly heavy components 900 requiring transport. The lifting component 600 can be detachably connected to either the first overlapping end 100 or the second abutting end 200. By applying force to the lifting component 600, the height of the connected portion can be precisely raised, eliminating the need for workers to directly lift heavy components to adjust their height, significantly reducing physical exertion. For example, when the first overlapping end 100 is connected to the external structure 910, the lifting component 600 can be used to raise the second abutting end 200 to a height similar to or equal to the first overlapping end 100. The pulley assembly 400 then easily pushes the component 900, avoiding the problem of single-person operation due to the excessive weight of heavy components. This changes the traditional multi-person collaborative lifting operation mode, allowing a single person to move and position the heavy component 900, significantly improving work efficiency. On the other hand, the lifting component 600 adopts a screw-rotated height adjustment mechanism or a gas spring structure, enabling precise height adjustment. It can accurately control the lifting height of the overlapping or abutting end according to the height of the external structure 910 and the disassembly / assembly requirements of the component 900 to be transported, ensuring that the final height matches the connection end height and preventing jamming or slippage of the component 900 during movement due to height deviation. Furthermore, the detachable design of the lifting component 600 allows it to be installed and used only when a height increase is required, eliminating the need for long-term fixation to the sliding auxiliary support 700 and preserving its portability in conventional scenarios. Moreover, regardless of whether the first overlapping end 100 or the second abutting end 200 is connected to the external structure 910, the connection points of the lifting component 600 can be changed to adapt to operational needs, further expanding the applicability of the sliding auxiliary support 700 in heavy structural component disassembly / assembly scenarios. On the other hand, compared to directly lifting the heavy transport component 900 by manpower, the lifting component 600 applies force stably and its height can be adjusted and controlled, which can avoid the transport component 900 from tilting or falling due to uneven manpower, and reduce the risk of falling from height and being injured by components.

[0070] The following will continue to combine Figures 1 to 10 The example illustrates the sliding auxiliary support 700. In some embodiments, the sliding auxiliary support 700 can be used for the installation and replacement of photovoltaic modules. It can also be referred to as a portable sliding auxiliary support for the installation and replacement of photovoltaic modules or a portable photovoltaic module auxiliary disassembly and assembly tool for on-site operations in photovoltaic power plants, i.e., it is applied in the field of photovoltaic power generation equipment installation and maintenance technology. Compared with traditional scaffolding or A-frame ladders that only provide a standing platform and do not have integrated functions such as module support, sliding, and positioning, the sliding auxiliary support 700 is particularly suitable for the safe and efficient installation and replacement of high-power and heavy photovoltaic modules in complex terrain or high-altitude operation scenarios. It can be used as a special auxiliary tool with a simple structure, safety and reliability, easy portability, and strong adaptability, which is conducive to improving the standardization and safety level of construction in the industry.

[0071] In some embodiments, the sliding auxiliary support 700 and its structural components, such as the first overlapping end 100, the second abutting end 200, and the main support 300, adopt an integrated lightweight structural design. For example, it is integrally welded from high-strength lightweight round steel, which has the advantages of compact structure, light weight, and high strength, making it easy for a single person to carry and for rapid on-site deployment. Furthermore, the sliding auxiliary support 700, through the cooperating main support 300 and pulley assembly 400, realizes a low-friction sliding system. For example, it integrates a double-sided pulley mechanism, which cooperates with the component to be transported 900, such as the photovoltaic module frame or mounting purlin, to achieve smooth sliding of the photovoltaic module on the mounting surface, significantly reducing the resistance of manual handling.

[0072] In some embodiments, the first overlapping end 100, the second abutting end 200, the main support 300, and the pulley assembly 400 of the sliding auxiliary support 700 adopt a modular and detachable design, which allows each component to be quickly assembled and disassembled, with a small storage volume, making it convenient for transportation and storage.

[0073] In some embodiments, the sliding auxiliary support 700 has an adaptive height adjustment function and can be optionally equipped with an adjustment rod 500, such as a telescopic rod structure, to adapt to photovoltaic arrays at different installation heights, improving tool versatility. In some embodiments, the sliding auxiliary support 700 has a ground-adaptive support structure, i.e., a bottom support structure. For example, the bottom support structure can finely adjust the contact angle according to the terrain, enhancing stability on uneven ground.

[0074] In some embodiments, the main support 300 serves as the load-bearing skeleton of the entire tool, bearing the weight of the components and transferring it to the ground support point. As an example, the main support 300 is constructed from high-strength, lightweight 6mm round steel, such as Q235 or a material with equivalent mechanical properties, integrally formed through bending and welding processes. As another example, the main support 300 has an I-beam or portal frame structure with a total length of 1340mm and an overall width of 100mm to ensure matching with the purlin spacing of standard photovoltaic modules.

[0075] In some embodiments, the pulley assembly 400 includes two sets of structures arranged symmetrically from left to right, such as a first pulley component 410 and a second pulley component 420. The first pulley component 410 and the second pulley component 420 are welded and fixed to both ends of the bottom of the main support, with a center distance of 965mm between the two pulleys to adapt to photovoltaic modules with a mainstream width of 1300mm to 1400mm. As an example, the pulley 403 of the pulley assembly 400, namely the pulley 403 of the first pulley component 410 and the pulley 403 of the second pulley component 420, adopts nylon-coated bearing pulleys with an outer diameter of approximately 50mm and a width of 25mm, and has characteristics such as wear resistance, quiet operation, and low friction. As an example, the pulley 403 is rigidly connected to the main support 300 through a mounting base 401, such as a welded bracket, to ensure that the pulley 403 does not wobble or shift during the sliding of the transported item 900.

[0076] In some embodiments, the adjusting rod 500 is an optional telescopic adjusting rod, with its rod body 510 being an inner and outer nested steel tube. The relative distance between the first portion 301 and the second portion 302 is adjusted by adjusting the length of the rod body 510 itself, thereby changing the overall length of the sliding auxiliary support 700. Alternatively, the rod body 510, the first rod body 310, and / or the second rod body 320 can form an inner and outer nested steel tube. The relative distance between the first portion 301 and the second portion 302 is adjusted by the movement of the rod body 510 relative to the first rod body 310 and / or the second rod body 320. As an example, the locking member 520 employs a locking knob or a snap-fit ​​mechanism to release or fix the rod body 510. As an example, the adjusting rod 500 or its rod body 510 is vertically welded or bolted to the top center of the main support 300 to adjust the overall length, i.e., the overall height, of the sliding auxiliary support 700 to accommodate transported items 900, such as photovoltaic support systems, at different tilt angles or heights.

[0077] The following example illustrates the manufacturing process of the sliding auxiliary support 700.

[0078] During the material preparation and inspection stage, Q235 round steel with a diameter of 6mm conforming to GB / T 700 standard was selected for random testing of tensile strength and bending performance.

[0079] Then, the material is cut and bent. The material is cut by laser or mechanical cutting according to the dimensions of the design drawings. Key parts, such as the main bracket 300, are bent at 90° at both ends to form L-shaped support legs.

[0080] Then, welding is performed, for example, using CO gas shielded welding or argon arc welding, to weld the first lap end 100 and the second abutment end 200 to the main bracket 300 as a whole; the mounting base 401 of the pulley assembly 400 is simultaneously welded and positioned.

[0081] Then, the pulleys are assembled. For example, the purchased pulley 403 is installed on the roller 402. The roller 402 is fixed to the mounting base 401 by bolts or welding to ensure that the pulley 403 rotates flexibly and without jamming.

[0082] Then, surface treatment is carried out, such as overall grinding to remove welding slag and burrs, and spraying anti-rust primer and outdoor weather-resistant topcoat such as epoxy resin paint to improve corrosion resistance.

[0083] Finally, quality inspection and packaging are carried out, such as load-bearing tests, smooth sliding tests, and structural stability tests. For example, the maximum load-bearing capacity is 250kg. After passing the tests, the product is packaged and shipped out of the factory.

[0084] The entire sliding auxiliary support 700 tool weighs no more than 10kg, can be carried by a single person, and does not require vehicle transportation, saving manpower and transportation costs. It is suitable for power plant operation and maintenance in complex environments.

[0085] In each embodiment, the sliding auxiliary support 700 uses the principle of lever support combined with rolling friction to transfer the weight of the item to be transported 900, such as a photovoltaic module, to the ground through the main support 300. At the same time, it forms rolling contact through the pulley assembly 400, transforming traditional sliding friction into rolling friction, which greatly reduces the pushing resistance. Therefore, in most cases, it can be moved easily by a single person.

[0086] The 700 sliding auxiliary support has several advantages. First, its stable bottom support structure and pulley support eliminate the need for manual lifting, reducing the risk of falls from heights and component damage, thus significantly improving operational safety. Second, a single person can complete component movement and positioning, theoretically reducing operation time by more than 50%, thereby greatly improving work efficiency. Third, its lightweight design, combined with the optional 500 adjustable rod, adapts to various complex terrains and installation heights, such as mountains, rooftops, and water surfaces, greatly enhancing environmental adaptability. Fourth, it uses rolling friction instead of dragging, avoiding frame scratches or glass cracks, thus reducing component damage rates.

[0087] The following example illustrates the specific usage of the sliding auxiliary support 700, using component replacement as an example to explain the standard usage procedure.

[0088] Tool Deployment:

[0089] Remove the main support 300 from the shipping package and place it directly;

[0090] Insert both ends of the main bracket 300 into the gap between the mounting purlins on both sides of the photovoltaic module or place it above the frame of the photovoltaic module.

[0091] Adjust the position of the main support 300 so that the pulley 403 of the pulley assembly 400 is in close contact with the glass surface or the upper edge of the frame of the photovoltaic module;

[0092] Slowly lower the main support 300 so that the pulley 403 supports the weight of the photovoltaic module. At this time, the original fixing blocks or clips of the photovoltaic module can be easily removed.

[0093] If equipped with a telescopic adjustment rod 500, the height can be finely adjusted to accommodate different installation angles.

[0094] Component sliding positioning:

[0095] The operator gently pushes the frame of the photovoltaic module with one hand, and the photovoltaic module slides smoothly along the mounting surface under the action of pulley 403;

[0096] After the photovoltaic modules are slid to the target position, such as the maintenance area or the new installation location, they can be temporarily fixed with support blocks.

[0097] New component installation:

[0098] The installation of a new component is the reverse operation of disassembly; place the new component on pulley 403 and push it to the installation position.

[0099] Align the mounting holes and install the pressure block or fastener;

[0100] Lift and remove the auxiliary tools to complete the installation.

[0101] Tool storage:

[0102] If there is a detachable adjustment rod 500, first remove the adjustment rod 500, then clean the pulley 403 and the main bracket 300, and put them into a special storage bag or box for easy use next time.

[0103] It should be noted that other embodiments of this application also include a sliding auxiliary support formed by combining the technical features of the above embodiments.

[0104] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0105] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
