Description

Technical Field

[0001] This utility model relates to a hoisting device, and more particularly to a hoisting device for an integral packaging box loaded with photovoltaic modules. Background Technology

[0002] Rooftop photovoltaic (PV) power generation is a new energy power generation method. In the construction of large-area rooftop PV power generation projects, the installation process of PV modules is as follows: First, the entire box of PV modules is transported to the ground next to the building where the PV modules are to be installed on the roof. Then, the packaging boxes containing the PV modules are unpacked, and each set of PV modules in the box is hoisted to the roof one by one. Finally, each set of PV modules is installed on the roof brackets. During the entire hoisting process, the hoisting slings are in direct contact with each set of PV modules. The lifting force of the hoisting slings will put pressure on the PV modules, often causing deformation of the PV modules after being stressed, as well as uneven stress on the PV panels, resulting in microcracks. This seriously affects the normal operation of the PV modules later, and may even lead to fire accidents during the operation of the PV panels. How to overcome the defects in this hoisting process has become a problem that needs to be solved on site. Summary of the Invention

[0003] This utility model provides a lifting device for an integrated packaging box loaded with photovoltaic modules, which enables convenient lifting and transport of the integrated packaging box filled with photovoltaic modules.

[0004] This utility model solves the above technical problems through the following technical solution: A lifting device for a complete packaging box containing photovoltaic modules includes the photovoltaic module packaging box, a box-shaped cage frame, a front horizontal lifting rod, a rear horizontal lifting rod, a front lifting rope, a rear lifting rope, and a hook. Two parallel front and rear support wooden beams are provided at the bottom of the photovoltaic module packaging box. A front strip-shaped gap is provided at the bottom of the photovoltaic module packaging box on the front side of the front support wooden beams, and a rear strip-shaped gap is provided at the bottom of the photovoltaic module packaging box on the rear side of the rear support wooden beams. The box-shaped cage frame is composed of horizontally arranged parallel first, second, third, and fourth rectangular frames, and vertically spaced rectangular frames. The enclosure consists of eight columns connected together. These four rectangular frames, when connected to the eight columns, form a closed box-shaped fence. The distance between the third and fourth rectangular frames is equal to the height of the front supporting wooden frame. The closed box-shaped fence is movably fitted onto the overall packaging box of the photovoltaic modules in the vertical direction. A front horizontal suspension rod is movably threaded between the third and fourth rectangular frames and in the front strip gap. A rear horizontal suspension rod is movably threaded between the third and fourth rectangular frames and in the rear strip gap. Front suspension ropes are connected to both ends of the front horizontal suspension rod, and rear suspension ropes are connected to both ends of the rear horizontal suspension rod. Hooks are connected to the middle of the front and rear suspension ropes.

[0005] A left annular groove is provided at the left end of the front horizontal boom, and a right annular groove is provided at the right end of the front horizontal boom; a left lifting ring is provided at the left end of the front lifting rope, and a right lifting ring is provided at the right end of the front lifting rope; a pair of left lifting rope limiting frames are provided on the left side of the first rectangular frame, and a pair of right lifting rope limiting frames are provided on the right side of the first rectangular frame.

[0006] The photovoltaic module packaging box is filled with photovoltaic modules.

[0007] The hoisting device of this utility model allows for hoisting by directly covering the outside of the photovoltaic module's overall packaging box with the cage, passing a rod through the photovoltaic module's packaging box pallet, and inserting the sling into the rod groove. This simple operation improves hoisting efficiency, especially since it enables hoisting without unpacking the photovoltaic modules, avoiding direct contact between the hoisting rope and the photovoltaic module.

Detailed Implementation

[0009] The present invention will now be described in detail with reference to the accompanying drawings: A lifting device for a complete packaging box containing photovoltaic modules includes a photovoltaic module packaging box 1, a box-shaped cage frame 6, a front horizontal lifting rod 12, a rear horizontal lifting rod 13, a front lifting rope 14, a rear lifting rope 15, and a hook 16. Two parallel front support ribs 2 and a rear support rib 3 are supported at the bottom of the photovoltaic module packaging box 1. The photovoltaic modules are loaded in a closed box above the two support ribs. A front strip-shaped gap 4 is provided at the bottom of the photovoltaic module packaging box 1 on the front side of the front support rib 2, and a rear strip-shaped gap 5 is provided at the bottom of the photovoltaic module packaging box 1 on the rear side of the rear support rib 3. These two strip-shaped gaps allow the horizontal lifting rods to be inserted, forming a complete packaging of the photovoltaic modules. The entire box 1 is lifted in a stretcher-like manner. The box-shaped cage frame 6 is composed of horizontally arranged parallel first rectangular frames 7, second rectangular frames 8, third rectangular frames 9, and fourth rectangular frames 10, connected by eight vertically spaced columns 11. These four rectangular frames and eight columns form a closed box-shaped enclosure. Multiple diagonal braces are also installed on the box-shaped enclosure frame to strengthen it. The distance between the third rectangular frame 9 and the fourth rectangular frame 10 is equal to the height of the front supporting wooden beam 2. The end of the horizontal suspension rod passes through the gap between the third rectangular frame 9 and the fourth rectangular frame 10 on one side, and then passes through the strip gap and the third rectangular frame 9 and the fourth rectangular frame 10 on the other side. The gap between the 10 rectangular frames allows for the overall lifting of the integrated photovoltaic module packaging box 1 and the box-shaped cage frame 6, which are fitted together. The enclosed box-shaped fence is movably fitted onto the integrated photovoltaic module packaging box 1 in the vertical direction. A front horizontal suspension rod 12 is movably connected between the third rectangular frame 9 and the fourth rectangular frame 10, and in the front strip gap 4. A rear horizontal suspension rod 13 is movably connected between the third rectangular frame 9 and the fourth rectangular frame 10, and in the rear strip gap 5.

Hooks 16 are connected to the middle of the front lifting rope 14 and the middle of the rear lifting rope 15. The lifting equipment uses the hooks... 16. The front suspension rope 14 and the rear suspension rope 15 lift the two horizontal rods upward, hoisting the integrated photovoltaic module packaging box 1 and the box-shaped cage frame 6 together to the roof. Then, the two suspension ropes are released to detach them from the two horizontal rods. The two horizontal rods are then pulled out from the bottom of the integrated photovoltaic module packaging box 1. Finally, the pulled-out two horizontal rods are inserted into the gap between the first rectangular frame 7 and the second rectangular frame 8. The two suspension ropes are connected to the inserted two horizontal rods. The lifting hook 16 is lifted by the lifting equipment to separate the box-shaped cage frame 6 from the integrated photovoltaic module packaging box 1. The box-shaped cage frame 6 is then hoisted to the ground to hoist the second integrated photovoltaic module packaging box 1.
