Description

Technical Field

[0001] This invention relates to the field of lifting device technology, specifically a solar panel mounting lifting device. Background Technology

[0002] Solar panels used for photovoltaic power generation are typically installed at high heights, such as on dedicated brackets or building rooftops. During installation, hoisting equipment is needed to lift and assist in transporting the solar panels to the designated height before workers install them. Currently, commonly used hoisting equipment includes cranes or simple lifting booms. During hoisting, slings and straps are typically used, and environmental factors such as wind can cause instability and swaying after lifting, easily leading to impact damage to the solar panels. Furthermore, because solar panels are relatively smooth, they can slip during lifting when secured with slings, posing not only safety hazards but also potential unnecessary economic losses.

[0003] Therefore, we proposed that a solar panel installation lifting device can effectively solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a solar panel installation and lifting device to solve the problems of instability and easy collision during the hoisting process and the easy slippage of solar panels mentioned in the background art, thereby reducing unnecessary economic losses.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a solar panel mounting and lifting device, comprising a main lifting column, wherein a slider is slidably engaged with the right side of the main lifting column, and the right end of the slider is fixed to a lifting plate;

[0006] It also includes: limiting side plates fixed on the front and rear sides of the upper surface of the lifting plate, and a sliding rod slidably connected inside the lifting plate, with the right end of the sliding rod fixed to the extension block, and a worm gear provided on the lower side of the extension block, with the upper end of the worm gear penetrating into the interior of the extension block;

[0007] The upper end of the worm and the extension block form a bearing connection, and a worm wheel meshes with the outer side of the worm, and the worm wheel is located inside the extension block.

[0008] The worm gear has a rotating shaft fixed in the middle, and both ends of the rotating shaft are connected to the extension block bearing. A gear is fixed on the outer side of the rotating shaft, and the right end of the gear meshes with the tooth block.

[0009] The toothed blocks are evenly distributed on the left side of the lifting rod, and the upper end of the lifting rod penetrates the upper surface of the extension block. At the same time, the lifting rod and the extension block form a sliding connection.

[0010] A pressure plate is fixed to the upper left side of the lifting rod, and a protective pad is adhered to the lower surface of the pressure plate.

[0011] Preferably, a limiting plate is provided on the upper surface of the lifting plate, and the limiting plate is slidably connected to the lifting plate through a return spring. Moreover, the two ends of the return spring are fixed to the lifting plate and the limiting plate respectively, and a protective pad is adhered to the inner side of the limiting plate.

[0012] The above structural design allows the reset spring to drive the limit plate to reset, and the protective pad can protect the solar panel.

[0013] Preferably, the slide rod is provided in two sets, and a row of locking holes is opened at equal intervals on the outer side of the two sets of slide rods, and the inside of the locking holes is engaged with the locking rod.

[0014] The above structural design allows for diverse extension and retraction lengths of the slide bar, enabling adjustments to achieve different lengths.

[0015] Preferably, the clamping rod is disposed on the front and rear sides of the lifting plate, and the clamping rod is slidably connected to the lifting plate through a tension spring, and the two ends of the tension spring are fixed to the lifting plate and the clamping rod respectively.

[0016] The above structural design allows the tension spring to drive the locking rod to reset.

[0017] Preferably, auxiliary pulleys are rotatably connected to the front and rear sides of the slider, and the outer side of the auxiliary pulleys is in contact with the main lifting column.

[0018] The above structural design allows the slider to rise and fall more effectively.

[0019] Preferably, a second cylinder is fixed on the upper surface of the main lifting column, and a sprocket is rotatably connected to the upper end of the second cylinder. The outer side of the sprocket meshes with a chain, and the left end of the chain is fixed to the main lifting column, while the right end of the chain penetrates into the main lifting column and is fixed to the slider.

[0020] The above structural design allows the chain to pull the slider upwards.

[0021] Preferably, a second sliding block is slidably connected to the lower surface of the main lifting column, and a second connecting rod is rotatably connected to the lower end of the second sliding block, and the other end of the second connecting rod is rotatably connected to the base.

[0022] The above structural design enables the second connecting rod and the second sliding block to form a linkage structure.

[0023] Preferably, the middle section of the second connecting rod is rotatably connected to the first connecting rod, and the upper end of the first connecting rod is rotatably connected to the lower surface of the main lifting column. At the same time, the lower end of the first connecting rod is rotatably connected to the first sliding block, and the first sliding block is slidably connected to the base. The right side of the first sliding block is fixed to the first cylinder, and the right end of the first cylinder is fixed to the base.

[0024] The above-described structure allows the cylinder to drive the first sliding block to slide, which in turn causes the first sliding block to drive the second connecting rod to move via the first connecting rod. Through the cooperation between the first and second connecting rods, a lifting effect is achieved.

[0025] Preferably, the first link and the second link form an "X" structure, and the first link and the second link form a linkage structure. Moreover, there are two sets of the first link and the second link in the front and rear positions, and the two sets of the first link and the second link are arranged in an overlapping structure when viewed from the front, and the two sets of the first link and the second link have the same structure.

[0026] The above structural design allows the two sets of first and second connecting rods to stably support the main lifting column.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows: This solar panel lifting device not only allows the pressure plate to contact the solar panel, thereby clamping and fixing the solar panel and preventing it from slipping and causing danger during the lifting process, thus improving its practicality, but also protects the solar panel from scratches by the limiting plate. Furthermore, the lifting device has a two-stage lifting structure, which can increase the lifting height, making the lifting height more diverse, and the lifting action is stable, adapting to various different heights. The specific details are as follows:

[0028] (1) The worm gear drives the worm wheel to rotate, which in turn drives the gear to rotate through the shaft. The gear then drives the lifting rod to descend through meshing with the tooth block, which in turn drives the pressure plate fixed on the left side of its top to move downward. This causes the pressure plate to contact the solar panel and clamp and fix the solar panel, thus preventing the solar panel from slipping during the lifting process and causing danger. It has good practicality.

[0029] Furthermore, the spring force of the reset spring causes the limiting plate to contact the solar panel, thereby limiting the position of the solar panel. At the same time, a protective pad is attached to the inner side of the limiting plate, which protects the solar panel and prevents the limiting plate from scratching it.

[0030] When it is necessary to remove the solar panel, simply reverse the worm gear, which in turn drives the worm wheel to reverse as well. This causes the worm wheel to drive the gear to reverse as well via the shaft. The gear then drives the lifting rod to rise through the meshing tooth blocks. This lifts the pressure plate away from the solar panel, thus releasing the limiting fixation on the solar panel.

[0031] (2) By pulling the slide bar and extension block to the right, the length of their limit is extended. When adjusted to the appropriate position, the locking bar can be released. At this time, the tension spring will cause the inner end of the locking bar to engage with the locking hole again, thereby limiting the limit of the slide bar and extension block, thus improving its performance and making it applicable to a wide range of applications.

[0032] (3) The second cylinder drives the sprocket connected to its upper end to rotate upward together, and the left end of the chain is fixed to the main lifting column, so that the right end of the chain will pull the slider to slide upward, thereby increasing the lifting height.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figures 1-9 The present invention provides the following technical solution:

[0045] Example 1: To address the problem in the prior art where the smooth surface of the solar panel causes it to slip during lifting, posing a safety hazard and potentially leading to unnecessary economic losses, the following solution is disclosed: A main lifting column 7 is included, with a slider 11 slidably engaged on its right side, and the right end of the slider 11 fixed to a lifting plate 13. The lifting plate 13 also includes: limit plates 15 fixed to the front and rear sides of its upper surface; a sliding rod 16 is slidably connected inside the lifting plate 13, with the right end of the sliding rod 16 fixed to an extension block 17; a worm gear 21 is provided on the lower side of the extension block 17, with its upper end penetrating into the interior of the extension block 17; a bearing connection is formed between the upper end of the worm gear 21 and the extension block 17; a worm wheel 22 meshes with the outer surface of the worm gear 21. Wheel 22 is located inside extension block 17; a rotating shaft 24 is fixed in the middle of worm gear 22, and both ends of the rotating shaft 24 are connected to the bearings of extension block 17. A gear 23 is fixed on the outer side of the rotating shaft 24, and the right end of the gear 23 meshes with a toothed block 25. The toothed blocks 25 are evenly distributed on the left side of lifting rod 26, and the upper end of lifting rod 26 penetrates the upper surface of extension block 17. Lifting rod 26 and extension block 17 are slidably connected. A pressure plate 27 is fixed on the upper left side of lifting rod 26, and a protective pad 28 is adhered to the lower surface of pressure plate 27. A limit plate 14 is provided on the upper surface of lifting plate 13, and the limit plate 14 is slidably connected to lifting plate 13 through a return spring 1402. The two ends of return spring 1402 are fixed to lifting plate 13 and limit plate 14 respectively. A protective pad 1401 is adhered to the inner side of limit plate 14.

[0046] First, place the solar panel on the lifting plate 13. Slide the limiting plate 14 to the left to prevent it from obstructing the solar panel. When the solar panel is on the lifting plate 13, release the limiting plate 14. The return spring 1402 then forces the limiting plate 14 to contact the solar panel, thus limiting its position. Simultaneously, a protective pad 1401 is adhered to the inner side of the limiting plate 14, protecting the solar panel and preventing scratches. The solar panel has limit plates 15 fixed on both the front and rear sides of the lifting plate 13. The limit plates 15 prevent the solar panel from sliding back and forth. By rotating the worm gear 21, the worm gear 21 drives the worm wheel 22 to rotate. The rotation of the worm wheel 22 drives the gear 23 to rotate through the shaft 24. The rotation of the gear 23 causes the gear 23 to mesh with the gear block 25, thereby driving the lifting rod 26 to rise and fall. The rise and fall of the lifting rod 26, in turn, drives the pressure plate 27 fixed on the left side of its top. The pressure plate 27 is lowered, thus contacting the solar panel and clamping it in place. A protective pad 28 is adhered to the lower surface of the pressure plate 27, providing both anti-slip and protection. Furthermore, the self-locking mechanism between the worm gear 21 and worm wheel 22 further enhances the clamping effect of the pressure plate 27, preventing it from shifting or loosening. This effectively prevents the solar panel from shifting and slipping during lifting, thus avoiding potential hazards. This practicality is significant. Okay, when it is necessary to remove the solar panel, simply reverse the worm gear 21, which will cause the worm gear 22 to reverse as well. This will cause the worm gear 22 to drive the gear 23 to reverse as well via the shaft 24. This will cause the gear 23 to drive the lifting rod 26 to rise through the meshing tooth block 25. This will cause the lifting rod 26 to move the pressure plate 27 away from the solar panel, thereby releasing the limiting fixation on the solar panel. At this time, simply move the limiting plate 14 to the left again so that the limiting plate 14 no longer limits the solar panel, and the solar panel can be removed.

[0047] Example 2: Unlike Example 1, this example allows for easy adjustment of the length of the lifting plate 13, making it suitable for different solar panels. When the solar panel is long, it can also be limited, resulting in a wider range of applications. See details for further information. Figures 1-6Two sets of slide rods 16 are provided, and a row of locking holes 18 are equally spaced on the outer side of both sets of slide rods 16. The inside of the locking holes 18 is engaged with the locking rod 19. The locking rod 19 is provided on the front and rear sides of the lifting plate 13. The locking rod 19 is slidably connected to the lifting plate 13 through the tension spring 20. The two ends of the tension spring 20 are fixed to the lifting plate 13 and the locking rod 19 respectively. The front and rear sides of the slider 11 are rotatably connected with auxiliary pulleys 12. The slider 11 is arranged in a "T" shape, and the outer side of the auxiliary pulley 12 is in contact with the main lifting column 7.

[0048] Furthermore, when the solar panel is long, simply pull the lever 19 outward to separate the inner end of the lever 19 from the locking hole 18, thereby releasing the sliding rod 16. At this point, the sliding rod 16 and the extension block 17 can be pulled to the right to extend their limiting length. When adjusted to the appropriate position, simply release the lever 19. The elastic force of the tension spring 20 will then cause the lever 19 to reset, allowing the inner end of the lever 19 to engage with the locking hole 18 again, thus limiting the sliding rod 16 and the extension block 17, thereby improving its performance and making it applicable to a wide range of applications.

[0049] Example 3: Unlike Example 2, this example improves the lifting effect on the solar panel. Furthermore, the lifting device has a two-stage lifting structure, which increases the lifting height and makes it more versatile, adapting to various height requirements. See details for further information. Figure 1 A second cylinder 8 is fixed to the upper surface of the main lifting column 7, and a sprocket 9 is rotatably connected to the upper end of the second cylinder 8. The outer side of the sprocket 9 meshes with a chain 10. The left end of the chain 10 is fixed to the main lifting column 7, while the right end of the chain 10 penetrates into the main lifting column 7 and is fixed to a slider 11. A second sliding block 6 is slidably connected to the lower surface of the main lifting column 7, and a second connecting rod 5 is rotatably connected to the lower end of the second sliding block 6. The other end of the second connecting rod 5 is rotatably connected to the base 1. The middle section of the second connecting rod 5 is rotatably connected to the first connecting rod 4, and the upper end of the first connecting rod 4 is connected to the main lifting column 7. The lower surface of the first connecting rod 4 is rotatably connected to the first sliding block 3, and the first sliding block 3 is rotatably connected to the base 1. The right side of the first sliding block 3 is fixed to the first cylinder 2, and the right end of the first cylinder 2 is fixed to the base 1. The first connecting rod 4 and the second connecting rod 5 form an "X" structure, and the first connecting rod 4 and the second connecting rod 5 form a linkage structure. There are two sets of the first connecting rod 4 and the second connecting rod 5 in the front and rear positions, and the two sets of the first connecting rod 4 and the second connecting rod 5 are arranged in an overlapping structure when viewed from the front. The two sets of the first connecting rod 4 and the second connecting rod 5 have the same structure.

[0050] Simultaneously, by activating the first cylinder 2, the first cylinder 2 drives the first sliding block 3 to slide to the right. The movement of the first sliding block 3 causes one end of the first connecting rod 4, which is rotatably connected to it, to move as well. Through the movable connection between the middle section of the first connecting rod 4 and the second connecting rod 5, the second connecting rod 5 drives the second sliding block 6 to slide to the right. This coordination between the first connecting rod 4 and the second connecting rod 5 lifts the main lifting column 7, raising its overall height. Then, by activating the second cylinder 8, its upper end rotates... The sprocket 9 is connected to the main lifting column 7 and moves upward together. The sprocket 9 drives the chain 10 upward as well. Since the left end of the chain 10 is fixed to the main lifting column 7, the right end of the chain 10 pulls the slider 11 upward. The auxiliary pulleys 12 connected to both sides of the slider 11 reduce frictional resistance, so that the auxiliary pulleys 12 work with the slider 11 to lift the lifting plate 13 as a whole, thereby achieving a stable lifting effect on the solar panel. Moreover, the lifting device is equipped with a two-stage lifting structure, which can increase the lifting height and make the lifting height more diverse to adapt to various different heights.
