Technical Field
[0001] This utility model relates to the field of large-area photovoltaic installation hoisting technology, specifically a hoisting device for large-area photovoltaic installation projects. Background Technology
[0002] Solar photovoltaic (PV) systems, also known as photovoltaics, are facilities that convert solar energy into direct current (DC) electricity using the photovoltaic effect of photovoltaic semiconductor materials. The core of a PV system is the solar panel. Currently, the main semiconductor materials used for power generation include monocrystalline silicon, polycrystalline silicon, amorphous silicon, and cadmium telluride. Due to the active promotion of renewable energy applications by various countries in recent years, the PV industry has developed rapidly. PV systems can be installed on a large scale on the ground to form PV power plants, or placed on the rooftops or exterior walls of buildings to form building-integrated photovoltaics (BIPV).
[0003] Photovoltaics, as a clean energy source, has developed rapidly in recent years. Photovoltaic solar panels can generate electricity that can be connected to the power grid, bringing benefits to the users. However, most large rooftops, such as those in factories, are idle. During the installation of photovoltaic solar panels, the height of factory rooftops makes the transportation and installation of photovoltaic panels inconvenient. Existing hoisting devices are large, and the steel cables used for hoisting can sway, which is not conducive to the stable placement of photovoltaic panels. Furthermore, the large size of the equipment makes transportation and relocation inconvenient and cannot be used for hoisting in narrow spaces such as different factories. Based on this, a hoisting device for large-area photovoltaic installation projects is proposed. Utility Model Content

Sliding rollers are movably installed inside the four mounting frames through bearings. Conical limiting rings are fixedly sleeved on the outer sides of both ends of the sliding rollers. Rubber sleeves are fixedly sleeved on the outer sides of the sliding rollers.
[0006] Preferably, the two telescopic frames and the limiting strip have convex openings, and the telescopic inner plate and the slide bar have convex closed openings.

[0018] 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.
[0019] Please see Figures 1-4 This utility model provides a technical solution: a hoisting device for large-area photovoltaic installation projects, including a base 1 and a placement frame 18. Four universal wheels 2 are fixedly installed at the bottom of the base 1. Four ground anchors 3 are movably inserted into the interior of the base 1. A hinge seat 4 is fixedly installed at the top of the base 1. A hinge rod 5 is movably inserted into the interior of the hinge seat 4. Two telescopic frames 6 are threadedly connected to the outer side of the hinge rod 5. Two limiting strips 7 are fixed to the outer side of each of the two telescopic frames 6. Several adjusting holes 8 are opened inside each of the two telescopic frames 6. Fixing bolts 9 are movably inserted into the adjusting holes 8. A telescopic inner plate 11 is movably sleeved inside each of the two telescopic frames 6. Several adjusting holes 13 are opened inside the telescopic inner plate 11. Sliding strips 12 are fixedly installed on the outer side of the telescopic inner plate 11. The inner plate 11 is connected to a hanging plate 10 at one end away from the telescopic frame 6. The other end of the hanging plate 10 is hinged to a hinge seat 14. A top seat 15 is fixedly installed at the bottom of the hinge seat 14. Four ground anchors 16 are movably inserted into the top seat 15. Four casters 17 are fixedly installed at the bottom of the top seat 15. Limiting side plates 21 are fixedly installed on both sides of the placement frame 18. A handle 19 is fixedly installed on the top surface of the placement frame 18. A limiting plate 20 is rotatably connected to the end of the placement frame 18 away from the handle 19. Four mounting frames 22 are fixedly installed on the bottom surface of the placement frame 18. Sliding rollers 23 are movably installed inside the four mounting frames 22 through bearings. Conical limiting rings 25 are fixedly sleeved on the outer sides of both ends of the sliding rollers 23. Rubber sleeves 24 are fixedly sleeved on the outer sides of the sliding rollers 23.
[0020] The working principle of the above technical solution is as follows: During use, the operator drags the base 1 and top seat 15 across the work site using casters 1 and 2 and 17, respectively. Once at the desired work position, the top seat 15 and hanging plate 10 are moved to the top of the roof. The telescopic inner plate 11 and telescopic frame 6 are then fitted together. After adjusting the tilt angle of the telescopic frame 6, the positions of the telescopic frame 6 and telescopic inner plate 11 are fixed by inserting fixing bolts 9 into adjusting holes 1 and 2 13. Next, ground anchor 1 3 is inserted into the ground, and ground anchor 2 16 is secured to the top seat 15 on the roof. Finally, a rope from the winding machine is used to secure the anchor. On the outside of the handle 19, the photovoltaic module is placed inside the placement frame 18. When the rope of the winding machine pulls the handle 19, the conical limiting ring 25 and the rubber sleeve 24 roll on the top of the limiting strip 7 and the slide bar 12 under the support of the sliding roller 23. The limiting of the conical limiting ring 25 keeps the sliding roller 23 at the top of the telescopic frame 6 and the telescopic inner plate 11. After the placement frame 18 is moved to the position of the hanging plate 10, the photovoltaic panel is taken out and the next hoisting process is carried out. The overall solution is easy to move in the factory environment, and the installation and transportation are convenient. It does not shake during hoisting, which increases safety.
[0021] In another implementation scheme, such as Figure 1 and Figure 2 As shown, the two telescopic frames 6 and the limiting strip 7 have convex openings, while the telescopic inner plate 11 and the slide bar 12 have convex closed openings. The specifications and dimensions of the telescopic inner plate 11 and the slide bar 12 are compatible with the specifications and dimensions of the telescopic frames 6 and the limiting strip 7.
[0022] The telescopic frame 6, the limiting strip 7, the telescopic inner plate 11, and the slide bar 12 are kept on the same horizontal plane through the opening, which facilitates the rolling plane support of the sliding roller 23 and the rubber sleeve 24, so that the flatness is not affected during adjustment. The overall length can be adjusted by the telescopic frame 6 and the telescopic inner plate 11 to adapt to the height of different factory buildings within a certain size range. The device can also be dragged by the movement of the universal casters 1 2 and universal casters 2 17, making transportation and movement convenient. By adjusting the tilt angle of the telescopic frame 6, it can be adapted to the erection in relatively narrow passages, increasing the convenience of use.
[0023] In another implementation scheme, such as Figure 1 and Figure 2 As shown, adjustment holes 1-8 are linearly and evenly distributed inside the telescopic frame 6, and adjustment holes 2-13 are linearly and evenly distributed inside the telescopic inner plate 11. The specifications and dimensions of the fixing bolts 9 are adapted to the specifications and dimensions of adjustment holes 1-8 and adjustment holes 2-13.
[0024] After adjustment, the fixing bolts 9 are inserted into the adjustment holes 1 and 2 (13) to fix the structure. The structure is simple, easy to adjust, has a long service life, and facilitates overall use.
[0025] In another implementation scheme, such as Figure 1 and Figure 2 As shown, the dimensions of the mounting plate 10 are compatible with the dimensions of the telescopic inner plate 11 and the slide bar 12. The mounting plate 10 is fixed to one end of the telescopic inner plate 11 by welding.
[0026] The hanging plate 10 is an arc-shaped extension of the same size as the telescopic inner plate 11 and the slide bar 12, which facilitates a slower turning method for the placement frame 18 and increases the stability of the structure. The hanging plate 10 is fixed to one end of the telescopic inner plate 11. In order to establish the hanging plate 10 and the telescopic inner plate 11 as an integral component, and the component without the hanging plate 10 installed on the telescopic inner plate 11, a telescopic inner plate 11 without the hanging plate 10 installed and a telescopic frame 6 can be spliced together. The telescopic inner plate 11 with the hanging plate 10 installed and the telescopic frame 6, which serves as a hinge support point, are spliced together, thereby extending the height of the support track for the placement frame 18 and further increasing the adaptability.
[0027] In another implementation scheme, such as Figures 2-4 As shown, the conical limiting ring 25 is distributed in a conical shape on the outer side of both ends of the sliding roller 23, the conical limiting ring 25 is located on the inner side of the mounting frame 22, and the rubber sleeve 24 is located on the opposite side of the conical limiting ring 25.
[0028] The tapered structure of the tapered limiting ring 25 causes the sliding roller 23 and the rubber sleeve 24 to be limited by the tapered limiting ring 25 when they roll from the limiting strip 7 to the top of the slide bar 12, reducing the shaking. The increased friction and deformation of the rubber sleeve 24 help maintain the relative stability of the structure, increasing the effectiveness of use and reducing deviation.
[0029] In another implementation scheme, such as Figures 2-4 As shown, four mounting frames 22 are symmetrically and evenly distributed at the bottom of the placement frame 18 in a rectangular shape. The positions of the four mounting frames 22 correspond to the positions of the telescopic frame 6 and the telescopic inner plate 11. The specifications and dimensions of the rubber sleeve 24 and the conical limiting ring 25 are adapted to the specifications and dimensions of the limiting strip 7 and the slide strip 12.
[0030] The mounting frame 22 provides stable and balanced support for the placement frame 18, increasing the relative stability of the structure. It facilitates the rolling structure of the sliding roller 23 and rubber sleeve 24 plus the conical limiting ring 25, rolling on the top of the limiting strip 7, the slide bar 12, the telescopic frame 6 and the telescopic inner plate 11, so as to achieve track-type support and limit, and facilitate the provision of support.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
