Description
Technical Field
[0001] This utility model is a photovoltaic construction hoisting device, belonging to the field of photovoltaic construction. Background Technology
[0002] In photovoltaic (PV) installation, a hanger consisting of four vacuum suction cups is a tool used to hoist PV modules and other equipment. The vacuum suction cups are created by a vacuum pump drawing air out of them, generating negative pressure that allows them to adhere to the surface of the object. The hanger, composed of four vacuum suction cups, utilizes the evenly distributed suction force to stably lift the PV modules. Aerial transport and installation positioning are then achieved through hoisting equipment connected to the hanger. In PV installation scenarios, PV panels vary significantly in size, requiring the vacuum suction cup spacing of the hanger to be flexibly adjustable. For large PV panels, the spacing between the four vacuum suction cups needs to be increased; conversely, for small PV panels, the spacing needs to be reduced accordingly. To address this, the hanger's horizontal plate is designed with an elongated oval opening. Nuts are used to secure the vacuum suction cups within this opening, allowing for convenient spacing adjustment.
[0003] However, this structure has significant drawbacks. It primarily relies on the static friction between the nut and the horizontal plate to secure the vacuum suction cup. When the hanger tilts during installation due to various factors, the friction between the nut and the horizontal plate is insufficient to resist the force generated by the tilt, easily causing the nut to slide relative to the horizontal plate, resulting in a displacement of the vacuum suction cup. This displacement not only disrupts the force balance during photovoltaic panel installation but may also lead to suction failure, causing the photovoltaic panel to fall. This poses a significant risk to construction safety and equipment integrity, and its stability and reliability fail to meet engineering requirements. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a photovoltaic construction hoisting device to solve the problems mentioned in the background technology. This utility model ensures the stability of the vacuum suction cup position, avoids the photovoltaic panel from falling due to force imbalance, and improves the safety of hoisting.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a photovoltaic construction hoisting device, comprising two symmetrically arranged horizontal plates, with two symmetrically arranged connecting plates between the two horizontal plates. The two ends of the connecting plates are connected to the two horizontal plates respectively by fasteners. Each horizontal plate has an elongated oval opening at both ends, into which a hollow tube is inserted. Two limiting nuts located on both sides of the horizontal plate are threaded onto the hollow tube. A suction cup is installed at the lower end of the hollow tube, and a support lug is installed on the hollow tube. A through hole is opened on one side of each support lug, into which a screw is inserted. The screw is arranged along the length of the horizontal plate, with one end connected to the horizontal plate. Two first nuts located on both sides of the support lug are threaded onto the screw.
[0006] Furthermore, a connector is fixedly connected to one end of the screw, and a connector hole is provided at the end of the screw away from the connector. The connector on one screw is inserted into the connector hole on another screw. A countersunk screw hole is provided on the outer surface of the end of the screw near the connector hole. An internal hex screw for limiting the position of the connector in the connector hole is threaded into the countersunk screw hole.
[0007] Furthermore, the connector and the screw are integrally formed, the connector has a rectangular cross-section, and the plug hole has a rectangular cross-section.
[0008] Furthermore, the four corners of the connector are all machined with a first rounded corner, and the four corners inside the connector hole are all machined with a second rounded corner.
[0009] Furthermore, support plates are installed at both ends of the horizontal plate, and a round hole is opened on one side of the support plate. One end of the screw passes through the round hole, and two second nuts located on both sides of the support plate are threaded to the end of the screw near the support plate.
[0010] Furthermore, two symmetrically arranged first ribs are fixedly connected to the lower surface of the cross plate, and the first ribs are arranged along the length direction of the cross plate.
[0011] Furthermore, two symmetrically arranged second ribs are fixedly connected to the upper surface of the connecting plate, and the second ribs are arranged along the length direction of the connecting plate.
[0012] Furthermore, both ends of the connecting plate are provided with multiple upper small holes arranged along the length of the connecting plate, and the horizontal plate and the area covered by the connecting plate are provided with lower small holes that cooperate with the upper small holes. A bolt is inserted into the channel formed by the upper small holes and the lower small holes, and a wing nut is threaded onto the bolt.
[0013] Furthermore, a lifting lug is installed at the middle position of the upper surface of the connecting plate, and the lifting lug is located between two rows of small holes on the connecting plate.
[0014] Furthermore, both ends of the horizontal plate are machined with a third rounded corner, and both ends of the connecting plate are machined with a fourth rounded corner.
[0015] The beneficial effects of this utility model are:
[0016] a. In the connection design between the hollow tube and the horizontal plate, not only are limiting nuts used to fix the hollow tube, but a combination structure of a screw and a first nut is also added to the lug of the hollow tube. Compared with the traditional method of fixing the vacuum suction cup solely by the static friction between the nut and the horizontal plate, this device has the additional limiting function of the screw. When the hanger tilts during hoisting, the screw can bear part of the force generated by the tilt, preventing the limiting nut from sliding relative to the horizontal plate, thereby ensuring the stability of the vacuum suction cup position and preventing the photovoltaic panel from falling due to force imbalance. This significantly improves the safety and integrity of the hoisting, and its stability and reliability far exceed those of traditional structures.
[0017] b. The elongated openings at both ends of the horizontal plate, along with the hollow tubes and limiting nuts, allow for convenient adjustment of the vacuum suction cup spacing. This flexibly adapts to the hoisting needs of photovoltaic panels of different sizes. Whether it's increasing the spacing required for large-sized photovoltaic panels or decreasing the spacing required for small-sized photovoltaic panels, it can be achieved quickly, effectively improving construction efficiency and enhancing the versatility of the device. The upper small holes at both ends of the connecting plate are connected to the lower small holes of the horizontal plate via bolts and wing nuts. This connection method facilitates installation and disassembly, allowing construction personnel to easily assemble and adjust the device according to the actual construction situation.
[0018] c. When assembling the screws, align the connector of one screw with the connector of another screw and insert it into the connector hole. Then tighten it with an Allen screw to fix the connector in its position within the connector hole. Repeat this process to assemble multiple screws. This assembly method is very flexible; the number of screws can be increased or decreased depending on the specific position of the vacuum suction cup (composed of the hollow tube and the suction cup) within the oblong opening.

Detailed Implementation
[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0026] Please see Figure 1 and Figure 3 This utility model provides a technical solution: a photovoltaic construction hoisting device, comprising two symmetrically arranged horizontal plates 1, with two symmetrically arranged connecting plates 9 between the two horizontal plates 1. Two symmetrically arranged first ribs 21 are fixedly connected to the lower surface of the horizontal plates 1, the first ribs 21 being arranged along the length direction of the horizontal plates 1. Two symmetrically arranged second ribs 22 are fixedly connected to the upper surface of the connecting plates 9, the second ribs 22 being arranged along the length direction of the connecting plates 9. A lifting lug 10 is installed at the middle position of the upper surface of the connecting plates 9, positioned between two rows of small holes 2 on the connecting plates 9. Both ends of the connecting plates 9 are open. Multiple small upper holes 2 are arranged along the length of the connecting plate 9. Both ends of the horizontal plate 1 are machined with third rounded corners, and both ends of the connecting plate 9 are machined with fourth rounded corners. The horizontal plate 1 and the area covered by the connecting plate 9 have small lower holes 18 that cooperate with the small upper holes 2. Bolts 4 are inserted into the channel formed by the small upper holes 2 and the small lower holes 18. A wing nut 3 is threaded onto the bolt 4. The small upper holes 2 at both ends of the connecting plate 9 and the small lower holes 18 of the horizontal plate 1 are connected by bolts 4 and wing nuts 3. This connection method is convenient for installation and disassembly, and allows construction personnel to assemble and adjust the device according to the actual construction situation.
[0027] See Figures 1-4The horizontal plate 1 has elongated openings 8 at both ends, with hollow tubes 7 inserted inside. Two limiting nuts 6 on either side of the horizontal plate 1 are threaded onto the hollow tubes 7. A suction cup 5 is installed at the lower end of the hollow tube 7, and a support lug 15 is installed on the hollow tube 7. A through hole 19 is opened on one side of the support lug 15, with a screw 11 inserted inside. The screw 11 is arranged along the length of the horizontal plate 1, with one end connected to the horizontal plate 1. Two first nuts 17 on either side of the support lug 15 are threaded onto the screw 11. The elongated openings 8 at both ends of the horizontal plate 1, in conjunction with the hollow tubes 7 and the limiting nuts 6, allow for convenient adjustment of the spacing of the vacuum suction cups 5. This allows for flexible adaptation to the hoisting needs of photovoltaic panels of different sizes. Whether it's increasing the spacing required for large-sized photovoltaic panels or reducing the spacing required for small-sized photovoltaic panels, it can be achieved quickly, effectively improving construction efficiency and enhancing the versatility of the device. In the connection design between the hollow tube 7 and the horizontal plate 1, not only is the hollow tube 7 fixed with the limiting nut 6, but a combination structure of screw 11 and first nut 17 is also added to the support lug 15 of the hollow tube 7. Compared with the traditional method of fixing the vacuum suction cup 5 by relying solely on the static friction between the nut and the horizontal plate 1, this device has the additional limiting function of screw 11. When the hanger tilts during the hoisting process, screw 11 can bear part of the component force generated by the tilt, preventing the limiting nut 6 from sliding relative to the horizontal plate 1, thereby ensuring the stability of the vacuum suction cup 5 and preventing the photovoltaic panel from falling due to force imbalance. This significantly improves the safety and integrity of the hoisting and its stability and reliability far exceed those of traditional structures.
[0028] See Figures 1-4Both ends of the horizontal plate 1 are equipped with support plates 12. One side of the support plate 12 has a round hole 20. One end of the screw 11 passes through the round hole 20. The end of the screw 11 near the support plate 12 is threaded with two second nuts 13 located on both sides of the support plate 12. The second nuts 13 cooperate with the support plate 12 to facilitate the assembly and disassembly of the screw 11 from the horizontal plate 1. One end of the screw 11 is connected and fixed with a connector 14. The connector 14 and the screw 11 are integrally formed. The four corners of the rectangular connector 14 are all machined with first rounded corners. The end of the screw 11 away from the connector 14 has a rectangular connector. The four corners of the insertion hole 23 are all machined with a second rounded corner. The connector 14 on one screw 11 is inserted into the insertion hole 23 on another screw 11. A countersunk screw hole 24 is opened on the outer surface of the end of the screw 11 near the insertion hole 23. The countersunk screw hole 24 is threaded with an internal hexagon screw 16 to fix the position of the connector 14 in the insertion hole 23. When assembling the screws 11, align the connector 14 of one screw 11 with and insert it into the insertion hole 23 of another screw 11, and then tighten it with the internal hexagon screw 16 to fix the position of the connector 14 in the insertion hole 23. By operating in this way, multiple screws 11 can be assembled. This assembly method is very flexible. The number of screws 11 can be increased or decreased according to the specific position of the vacuum suction cup 5 formed by the hollow tube 7 and the suction cup 5 in the elongated opening 8.
