Description

Technical Field

[0001] This utility model relates to the technical field of the photovoltaic industry, and in particular to a hoisting device for photovoltaic panels. Background Technology

[0002] As a core component of clean energy power generation, photovoltaic (PV) panels typically involve transporting large, fragile panels from the ground and precisely positioning them onto a support system. Especially when installing on sloping ground, rooftops, or in spaces with limited space, traditional manual handling methods are inefficient, labor-intensive, and prone to damage due to bumps and uneven stress, leading to economic losses and safety hazards. Therefore, a specialized PV panel hoisting device is needed to achieve safe, efficient, and damage-free hoisting operations.

[0003] Existing photovoltaic panel hoisting devices typically employ simple clamping mechanisms or slings for fixation. These devices have significant shortcomings during hoisting, including uneven clamping force and the risk of damage. Existing clamping mechanisms often fail to ensure that multiple clamping points apply force synchronously and evenly to the edges of the photovoltaic panel. Uneven clamping force or localized stress concentration can easily lead to microcracks or breakage of the photovoltaic panel glass or cells during hoisting. Position adjustment is difficult and fixation is insecure. After initial clamping, the photovoltaic panel often requires fine-tuning to ensure accurate positioning and secure fixation on the support frame due to installation accuracy requirements or slight wobbling. Existing devices generally lack convenient and effective fine-tuning mechanisms, making the adjustment process time-consuming and labor-intensive, and making it difficult to ensure the final clamping stability, posing a risk of loosening or displacement during hoisting. Operational convenience is poor; clamping and fine-tuning operations are often not convenient or labor-saving, affecting overall installation efficiency. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a photovoltaic panel hoisting device, which aims to improve the safe, stable, and damage-free clamping of photovoltaic panels of different specifications, and to avoid cracking caused by uneven clamping force, as well as the problem of slight positional deviation or insufficient firmness of photovoltaic panels after foundation clamping.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a photovoltaic panel hoisting device, comprising a rotating base, a lower joint of a boom fixedly connected to the upper surface of the rotating base, an upper joint of a boom rotatably connected to the inner wall of the lower joint, a hydraulic push rod rotatably connected to the inner wall of the lower joint, a fixing plate fixedly connected to the outer wall of the upper joint, a drum rotatably connected to the outer wall of the fixing plate, a wire rope provided on the outer wall of the drum, frames suspended at both ends of the wire rope, a clamping assembly provided on the inner wall of the frame, and an adjusting and fixing assembly provided on the outer wall of the frame;

[0006] The clamping assembly includes a threaded rod, the outer wall of which is threadedly connected to the inner wall of the frame. One end of the threaded rod is fixedly connected to a slider, and a rotating plate is rotatably connected to the outer wall of the frame. Two symmetrical fixing rods are respectively provided at both ends of the rotating plate. One end of each fixing rod is rotatably connected to a fixing block, and the outer wall of the fixing block is fixedly connected to a slider. A guide tube is slidably connected to the inner wall of the slider, and a clamping arm is fixedly connected to the outer wall of the slider.

[0007] Furthermore, the adjusting and fixing assembly includes a pressing handle, which is disposed on the inner wall of the frame. A fixing plate two is rotatably connected to the outer wall of the pressing handle. A connector is rotatably connected to the outer wall of the pressing handle. A telescopic rod is rotatably connected to the outer wall of the connector. A fixing plate three is fixedly connected to the outer wall of the telescopic rod. A clamping plate is fixedly connected to one end of the telescopic rod. A slider two is fixedly connected to the outer wall of the clamping plate. A sliding groove is slidably connected to the outer wall of the slider two.

[0008] Furthermore, the two ends of the guide tube are fixedly connected to the outer wall of the frame, and the slider is disposed on the inner wall of the frame.

[0009] Furthermore, the output end of the hydraulic push rod is rotatably connected to the outer wall of the joint on the boom, and the hydraulic push rod is positioned above the rotating base.

[0010] Furthermore, the clamping plate is disposed on the outer wall of the clamping arm.

[0011] Furthermore, the groove is formed on the inner wall of the clamping arm, and the clamping arm is disposed on the inner wall of the frame.

[0012] Furthermore, the lower surface of the third fixing plate is fixedly connected to the outer wall of the clamping arm, and the lower surface of the second fixing plate is fixedly connected to the outer wall of the clamping arm.

[0013] Furthermore, the fixing block is disposed on the inner wall of the frame.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by rotating the threaded rod, the threaded rod drives the slider connected to it to move linearly along the guide tube. The movement of the slider causes the fixed block to move, which in turn pushes the fixed rod. The fixed rod pulls the rotating plate, efficiently converting the linear motion of the slider into the synchronous opening and closing motion of the clamping arms. Ultimately, this ensures that the clamping plate fixed on the clamping arms firmly clamps or safely releases the photovoltaic panel. The synchronous and smooth opening and closing of the clamping arms is achieved through the threaded rod transmission, the fixed rod, and the rotating plate, ensuring that a uniform clamping force is applied to the photovoltaic panel and avoiding damage from localized stress.

[0016] 2. In this utility model, operating the pressing handle causes it to rotate around its connection point with the fixed plate, simultaneously driving the connecting component to move. The connecting component pushes or pulls the telescopic rod, causing the telescopic rod to extend and retract, thus driving the clamping plate fixedly connected to it to slide horizontally along the slide groove, achieving fine-tuning of the clamping position. This provides the ability to finely adjust the clamping position of the clamping plate, ensuring that the photovoltaic panel is accurately centered and firmly clamped within the frame without shaking. The pressing handle and connecting component mechanism make fine-tuning operations labor-saving and convenient. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-3This utility model provides an embodiment of a photovoltaic panel hoisting device, including a rotating base 1, which provides a stable installation foundation for the entire hoisting device and enables the boom to rotate 360 ​​degrees in the horizontal plane to accurately position the hoisting direction. A lower boom joint 3 is fixedly connected to the upper surface of the rotating base 1. An upper boom joint 4 is rotatably connected to the inner wall of the lower boom joint 3. A hydraulic push rod 2 is rotatably connected to the inner wall of the lower boom joint 3. Through its extension and retraction movement, the upper boom joint 4 is driven to rotate relative to the lower boom joint 3, thereby adjusting the pitch angle of the boom and changing the hoisting height and amplitude. A fixing plate 5 is fixedly connected to the outer wall of the upper boom joint 4. A drum 6 is rotatably connected to the outer wall of the fixing plate 5. The fixing plate 5 is fixed at the far end of the upper boom joint 4 to provide an installation support and rotation support for the drum 6. A steel wire rope 7 is provided on the outer wall of the drum 6. A frame 8 is suspended at both ends of the steel wire rope 7. A clamping component is provided on the inner wall of the frame 8, and an adjustment and fixing component is provided on the outer wall of the frame 8.

[0026] The clamping assembly includes a threaded rod 9, whose outer wall is threadedly connected to the inner wall of the frame 8. A slider 10 is fixedly connected to one end of the threaded rod 9. The threaded rod 9 serves as the main drive shaft of the clamping assembly; its rotation is converted into linear motion through a threaded joint, driving the slider 10 to move. It is the power input point for clamping and releasing actions. A rotating plate 16 is rotatably connected to the outer wall of the frame 8. Symmetrical fixing rods 15 are provided at both ends of the rotating plate 16. The fixing rods 15 pull the rotating plate 16 to rotate, and the rotating plate 16 is then rotated by another… The fixing rod 15 on one side pulls the slider 10 on the other side to move in the opposite direction, ensuring that the clamping plates 13 on both sides clamp or loosen synchronously. One end of the fixing rod 15 is rotatably connected to the fixing block 14. The slider 10 is fixedly connected to the outer wall of the fixing block 14. The guide tube 11 is slidably connected to the inner wall of the slider 10. The guide tube 11 is fixedly installed on the frame 8 to provide a precise linear motion track for the slider 10, ensuring that the clamping action is smooth and centered, and bearing the lateral force generated by the clamping force. The outer wall of the slider 10 is fixedly connected to the clamping arm 12.

[0027] Specifically, when the frame 8 descends to the position of the photovoltaic panel to be clamped, the operator rotates the threaded rod 9. The threaded rod 9 engages with the threaded hole on the inner wall of the frame 8 through its outer thread. The slider 10 is directly fixedly connected to one end of the threaded rod 9. Therefore, the slider 10 is driven by the threaded rod 9 to slide linearly along the outer wall of the guide tube 11. The movement of the slider 10 causes the fixed block 14 fixedly connected to it to move synchronously. The movement of the fixed block 14 is transmitted through the fixed rod 15, which is rotatably connected to itself. The other end of the fixed rod 15 is rotatably connected to one end of the rotating plate 16. Therefore, the fixed rod 15 will pull... The rotating plate 16 is rotatably connected to the outer wall of the frame 8. Symmetrical hinge points are provided at both ends of the rotating plate 16. When the rotating plate 16 is driven to rotate by the fixed rod 15 on one side, the hinge point at the other end will pull the fixed block 14 on the other side and the other slider 10 fixed thereto through another symmetrically arranged fixed rod 15, so that it moves in a straight line in the opposite direction along the guide tube 11. Therefore, the clamping arm 12 fixedly connected to the outer wall of the slider 10 and the clamping plate 13 installed at the end of the clamping arm 12 also open and close synchronously with the slider 10, thereby clamping or loosening the left and right edges of the photovoltaic panel.

[0028] Reference Figures 4-5 The adjusting and fixing assembly includes a pressing handle 19, which is located on the inner wall of the frame 8. The manually operated lever, when pressed down or raised, drives the connecting piece 21 and the telescopic rod 23 to move via a lever principle. A fixing plate 20 is rotatably connected to the outer wall of the pressing handle 19, providing a fulcrum for the pressing handle 19 on the clamping arm 12. The connecting piece 21 is rotatably connected to the outer wall of the pressing handle 19, and the telescopic rod 23 is rotatably connected to the outer wall of the connecting piece 21. The connecting piece 21 transmits the movement of the pressing handle 19 to the telescopic rod 23. A fixing plate 22 is fixedly connected to the outer wall of the telescopic rod 23, providing a fixed support fulcrum for the telescopic rod 23 on the clamping arm 12. A clamping plate 13 is fixedly connected to one end of the telescopic rod 23, and the extension and retraction of the telescopic rod 23 directly drives the clamping plate 13 at its end. 3. A slider 17 is fixedly connected to the lower surface of the clamping plate 13. A groove 18 is slidably connected to the outer wall of the slider 17, providing a precise linear sliding track for adjusting the slider 17 of the fixing component and constraining its movement direction to be perpendicular to the photovoltaic panel plane. The two ends of the guide tube 11 are fixedly connected to the outer wall of the frame 8. The slider 10 is set on the inner wall of the frame 8. The output end of the hydraulic push rod 2 is rotatably connected to the outer wall of the upper joint 4 of the boom. The hydraulic push rod 2 is set above the rotating base 1. The clamping plate 13 is set on the outer wall of the clamping arm 12. The groove 18 is opened on the inner wall of the clamping arm 12. The clamping arm 12 is set on the inner wall of the frame 8. The lower surface of the fixing plate 22 is fixedly connected to the outer wall of the clamping arm 12. The lower surface of the fixing plate 20 is fixedly connected to the outer wall of the clamping arm 12. The fixing block 14 is set on the inner wall of the frame 8.

[0029] Specifically, after the photovoltaic panel is initially clamped by the two side clamping plates 13, in order to ensure that its position within the frame 8 is completely centered and secure without loosening, and to prevent shaking or displacement during hoisting, it is necessary to operate the adjustment and fixing components. The operator presses down or lifts the pressing handle 19 set on the inner wall of the frame 8. The pressing handle 19 moves with the fixing plate 20 as the fulcrum. Since the outer wall of the fixing plate 20 is rotatably connected to the pressing handle 19, and the lower surface of the fixing plate 20 is firmly fixed to the outer wall of the clamping arm 12, the movement of the pressing handle 19 is transmitted to the connector 21 through another rotatable connection point on its outer wall. The connector 21 also moves accordingly, thereby pulling the telescopic rod 23 rotatably connected to the connector 21. The telescopic rod 23 moves in extension and retraction under the action of the connector 21. A fixing plate 22 is fixedly installed on the upper part of the clamping arm 12. The lower surface of the fixing plate 22 is also firmly fixed to the outer wall of the clamping arm 12, providing a stable support point for the middle part of the telescopic rod 23. The telescopic end of the telescopic rod 23 is fixedly connected to the clamping plate 13. In order to ensure that the movement trajectory of the clamping plate 13 does not change, a slider 17 is fixedly connected to the lower surface of the clamping plate 13. The outer wall of the slider 17 is slidably connected to the groove 18 opened in the inner wall of the clamping arm 12. Therefore, when the telescopic rod 23 extends or retracts, the telescopic rod 23 drives the clamping plate 13 fixedly connected to it. The clamping plate 13 slides horizontally along the direction defined by the groove 18 in the inner wall of the clamping arm 12 through the slider 17 below. By lifting and pressing the handle 19, the position of the clamping plate 13 can be finely adjusted in the horizontal direction to clamp and loosen the photovoltaic panel.

[0030] Working principle: When photovoltaic panels need to be hoisted, the rotating base 1 provides horizontal rotation capability. The hydraulic push rod 2 extends and retracts to drive the upper joint 4 of the boom to rotate relative to the lower joint 3 of the boom, thereby adjusting the boom angle. The fixed plate 5 fixes the drum 6 to the upper joint 4 of the boom. The drum 6 rotates to wind up and unwind the wire rope 7, driving the frame 8 suspended at both ends to rise and fall. When it is necessary to clamp the photovoltaic panel, the threaded rod 9 is rotated. The rotation of the threaded rod 9 drives the slider 10 connected to it to move linearly along the guide tube 11. The movement of the slider 10 drives the fixed block 14 to move, which in turn pushes the fixed rod 15. The fixed rod 15 pulls the rotating plate 16. The rotating plate 16 is hinged at both ends, converting the linear movement of the slider 10 into the synchronous opening and closing movement of the clamping arm 12, ultimately causing the clamping plate 13 fixed on the clamping arm 12 to clamp or release the photovoltaic panel.

[0031] After clamping the photovoltaic panel, operate the pressing handle 19. The pressing handle 19 rotates around its connection point with the second fixing plate 20, which in turn drives the connecting piece 21 to move. The connecting piece 21 pushes or pulls the telescopic rod 23, which extends and retracts, causing the clamping plate 13, which is fixedly connected to it, to slide horizontally along the slide groove 18. The second slider 17 guides within the slide groove 18, enabling fine-tuning of the clamping position of the clamping plate 13, ensuring that the photovoltaic panel is firmly clamped within the frame 8. The third fixing plate 22 and the second fixing plate 20 are respectively fixed on the clamping arm 12, providing support points for the telescopic rod 23 and the pressing handle 19.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
