[0001] The utility model belongs to the technical field of photovoltaic panel installation equipment, in particular to a lifting device for installing a solar photovoltaic panel. Background Art

[0002] When solar photovoltaic panels are installed on ground brackets, they need to be lifted. The common operation method is: two to four workers stand on a suspended working platform, and one to two workers stand on the ground. The workers on the ground lift the photovoltaic panels and send them to a high place. The workers at the high place catch the photovoltaic panels and pull them onto the bracket.

[0003] The above-mentioned manual method of lifting photovoltaic panels is relatively practical, but it has defects: first, the workers do not cooperate well with each other, and the photovoltaic panels are easy to fall and break or injure the workers on the ground; second, it is more physically demanding for the workers; third, only one photovoltaic panel can be lifted at a time, and the lifting efficiency is low. Utility Model Content

[0008] The movable plate is slidably mounted on the front face of the inclined support plate, and the movable plate can rise or fall along the inclined surface on the inclined support plate. A plurality of side baffles spaced apart from each other are mounted on the left and right sides of the front face of the movable plate, and a plurality of bottom baffles spaced apart from each other are mounted on the bottom of the front face. When the photovoltaic panel is placed on the front face of the movable plate, the plurality of bottom baffles support the photovoltaic panel from the bottom end to prevent the photovoltaic panel from sliding off the movable plate, and the plurality of side baffles enclose the photovoltaic panel from the left and right sides to prevent the photovoltaic panel from tipping over from the side of the movable plate. When the movable plate rises along the inclined surface of the inclined support plate, it can drive the photovoltaic panel to rise.

[0009] The threading ring is fixed at the center of the bottom back of the movable plate. A clearance groove is provided on the inclined support plate for the threading ring to be raised and lowered along the inclined surface. The threading ring can be raised and lowered on the inclined support plate along with the movable plate. When the threading ring rises to the top of the clearance groove, it cannot continue to rise, which has a limiting effect and can prevent the movable plate from detaching from the top of the inclined support plate.

[0010] The motor is installed on the base; the reel is installed on the power output end of the motor, and the motor is used to drive the reel to rotate forward or reverse;

The wire rope is wound on the fixed pulley. The reel is used to reel in and unreel the wire rope. The motor drives the reel to rotate forward or reverse to reel in or unreel the wire rope, thereby realizing the lifting and lowering of the movable plate.

[0012] When the wire rope is wound, the wire rope lifts the movable plate, causing the movable plate to rise along the slope on the inclined support plate to lift the photovoltaic panel placed on the movable plate; when the wire rope is unwound, under the action of the gravity of the movable plate, it descends along the slope on the inclined support plate to a low position.

[0013] It is further defined that a plurality of running wheels with brakes are installed at the bottom of the base to facilitate the movement and parking of the lifting device.

[0014] Further defined, a push frame is installed at the left end of the base, and the base, walking wheels and push frame form a flatbed cart, which is convenient for workers to push the lifting device to move.

Each L-shaped guide rail is provided with a slide, and the slide is fixed to the L-shaped guide rail by bolts, and the installation position of the slide on the L-shaped guide rail can be adjusted along the front and rear directions. The two inclined support rods correspond one by one to the two slides, and the top end of the inclined support rod is hinged to the back side of the inclined support plate, and the bottom end thereof is hinged to the slide; by adjusting the installation position of the slide on the L-shaped guide rail along the front and rear directions, the inclination angle of the inclined support plate can be adjusted, which is convenient for workers on the suspended work platform to extract photovoltaic panels.

[0017] Further definition, limiting sleeves are installed on the two side baffles opposite to each other on the left and right sides of the middle position of the movable plate, and a cross baffle is arranged between the two limiting sleeves. Pins are fixed on the left and right ends of the cross baffle, and the two pins are respectively inserted into the two limiting sleeves to make the cross baffle removable. When the photovoltaic panel is placed on the movable plate, the installed cross baffle can protect the photovoltaic panel from the front side of the movable plate. The cross baffle blocks the middle position of the photovoltaic panel laterally to prevent the photovoltaic panel from tipping forward.

[0018] According to a further definition, the lifting device also includes at least one foam partition plate for separating photovoltaic panels. When multiple photovoltaic panels are placed overlappingly on a movable plate and lifted at the same time, a foam partition plate is laid between two adjacent overlapping photovoltaic panels. After the photovoltaic panels are lifted, when workers at a high place lift and unload the photovoltaic panels one by one from the movable plate, the surface of the photovoltaic panels can be avoided from being scratched under the protection of the foam partition plate.

[0019] As a further limitation, a battery for powering the motor is installed on the top surface of the base, so that the lifting device is not restricted by power supply and can be used flexibly.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

Multiple photovoltaic panels can be placed on a movable plate in an overlapping manner, and multiple photovoltaic panels can be lifted at one time to improve work efficiency. The motor can control the reel to rotate forward or reverse to reel in or unreel the wire rope. When reeling in the wire rope, the movable plate is pulled up along the inclined surface on the inclined support plate by the wire rope to lift the photovoltaic panels placed on the movable plate.

[0029] In this embodiment, Figures 1 to 4 As shown, four running wheels 10 with brakes are installed at the bottom of the base 1, which can facilitate the movement and parking of the lifting device; a push frame 2 is installed at the left end of the base 1, and the base 1, running wheels 10 and push frame 2 form a flatbed cart, which is convenient for workers to push the lifting device to move;

[0030] The base 1 is made of steel plates, and the push frame 2 is welded from stainless steel square tubes.

[0031] In this embodiment, Figure 1 、 Figure 3 and Figure 4 As shown, the bottom end of the oblique support plate 3 is hinged on the base 1, and two oblique support rods 12 are provided on the rear side of the oblique support plate 3 along the left-right direction. The top surface of the base 1 is provided with two L-shaped guide rails 11 spaced along the left-right direction and extending along the front-back direction. Each L-shaped guide rail 11 is provided with a slide 13, which is fixed to the L-shaped guide rail 11 by bolts, and the installation position of the slide 13 on the L-shaped guide rail 11 can be adjusted along the front-back direction. The two oblique support rods 12 correspond to the two slides 13 one by one. The top end of the oblique support rod 12 is hinged to the back side of the oblique support plate 3, and the bottom end thereof is hinged to the slide 13.

[0032] The above structure makes the inclined support plate 3 inclined on the base 1. By adjusting the installation position of the slide 13 on the L-shaped guide rail 11 in the front-back direction, the inclination angle of the inclined support plate 3 can be adjusted. It is explained here that the front side of the inclined support plate 3 refers to Figure 2 The front side and the back side of the oblique support plate 3 are Figure 2 In the back side.

[0033] Specifically, if Figure 1 、 Figures 3 to 5 As shown, two T-shaped plates spaced apart in the left-right direction are welded to the bottom of the back of the oblique support plate 3, and two hinge seats 9 spaced apart in the left-right direction are welded to the top surface of the base 1. The two T-shaped plates correspond to the two hinge seats 9 one-to-one, and both the T-shaped plates and the hinge seats 9 are provided with jacks for inserting hinge shafts. The T-shaped plates are hinged to the hinge seats 9, so that the bottom end of the oblique support plate 3 can rotate relative to the base 1.

[0034] Two hinged seats 9 spaced apart in the left-right direction are welded to the top of the back of the oblique support plate 3. The two hinged seats 9 correspond one to one with the two slides 13. A slide groove extending in the front-back direction is provided on the top surface of the L-shaped guide rail 11. The slide 13 and the L-shaped guide rail 11 are connected by bolts inserted into the slide groove. After loosening the bolts, the slide 13 can be moved along the slide groove to adjust the installation position of the slide 13 on the L-shaped guide rail 11. After the position is adjusted to the right position, the bolts are retightened to fix the slide 13.

[0035] The hinge seat 9 on the back of the inclined support plate 3 and the slide 13 installed on the L-shaped guide rail 11 are both provided with a socket for inserting the hinge shaft. The two ends of the inclined support rod 12 are respectively hinged to the hinge seat 9 and the slide 13. When the installation position of the slide 13 is adjusted, the inclined support rod 12 rotates relative to the hinge seat 9 and the slide 13 to adjust the inclination angle of the inclined support plate 3.

[0036] In this embodiment, Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, the movable plate 4 is slidably mounted on the front side of the inclined support plate 3, and the movable plate 4 can rise or fall along the inclined surface on the inclined support plate 3. Three side baffles 5 spaced apart from each other are installed on the left and right sides of the front of the movable plate 4, and two bottom baffles 6 spaced apart from each other are installed on the bottom of the front. When the photovoltaic panel is placed on the front of the movable plate 4, the two bottom baffles 6 support the photovoltaic panel from the bottom end to prevent the photovoltaic panel from sliding off the movable plate 4. The six side baffles 5 enclose the photovoltaic panel from the left and right sides to prevent the photovoltaic panel from tipping over from the side of the movable plate 4. When the movable plate 4 rises along the inclined surface of the inclined support plate 3, it can drive the photovoltaic panel to rise.

[0037] Specifically, the oblique support plate 3 is composed of a base plate, a flange set at the bottom of the front side of the base plate, and L-shaped baffles set on the left and right sides of the front side of the base plate. The flange at the bottom of the base plate can support the bottom end of the movable plate 4 and limit the movable plate 4. The two L-shaped baffles and the left and right ends of the base plate respectively form a slot extending along the inclined surface. The left and right ends of the movable plate 4 are respectively engaged in the slot, which can prevent the movable plate 4 from separating from the movable plate 4 when it moves.

[0038] The above-mentioned inclined support plate 3, movable plate 4, side baffle 5 and bottom baffle 6 are all made of steel plate or aluminum alloy.

[0039] In this embodiment, Figures 3 to 5 As shown, the threading ring 21 is fixed at the center position of the bottom back of the movable plate 4, and a clearance groove 20 is provided on the inclined support plate 3 for the threading ring 21 to be raised and lowered along the inclined surface. The threading ring 21 can be raised and lowered on the inclined support plate 3 along with the movable plate 4. When the threading ring 21 rises to the top of the clearance groove 20, it can no longer continue to rise, which has a limiting effect and can prevent the movable plate 4 from detaching from the top of the inclined support plate 3.

[0040] In this embodiment, Figure 1 and Figure 3 As shown, the motor 15 and the battery 17 are both mounted on the top surface of the base 1, the motor 15 is electrically connected to the battery 17, and the reel 16 is mounted on the power output end of the motor 15, and the motor 15 is used to drive the reel 16 to rotate forward or reverse; using the battery 17 to power the lifting device, the lifting device is not limited by the power supply and can be used flexibly;

[0041] Among them, the motor 15 is a forward and reverse motor and is equipped with a reducer. A switch for controlling the forward and reverse rotation of the motor 15 is installed on the push frame 2. The motor 15 is connected in series to the connection circuit between the motor 15 and the battery 17. The technical method for controlling the forward and reverse rotation of the motor 15 is a well-known technology and will not be repeated here.

[0042] In this embodiment, Figures 3 to 5 As shown, one end of the wire rope 18 is fixed on the threading ring 21, and the other end thereof is wound on the reel 16. A fixed pulley 19 is fixed at the top center position of the back side of the inclined support plate 3. The wire rope 18 is wound on the fixed pulley 19. The reel 16 is used to wind up and unwind the wire rope 18. The reel 16 is driven by the motor 15 to rotate forward or reverse to wind up or unwind the wire rope 18, thereby realizing the lifting and lowering of the movable plate 4.

[0043] In this embodiment, Figure 1 、 Figures 3 to 5 As shown, a U-shaped gantry 14 is provided on the rear side of the inclined support plate 3. The bottom end of the U-shaped gantry 14 is welded to the base 1. A fixed pulley 19 for guiding the wire rope 18 is installed on the top of the U-shaped gantry 14. The wire rope 18 is guided by the two fixed pulleys 19 to make its winding and unwinding smoother.

[0044] The U-shaped gantry 14 is made of stainless steel square tubes.

[0045] In this embodiment, Figure 1 and Figure 2 As shown, the two side baffles 5 at the left and right sides of the middle position of the movable plate 4 are both installed with limiting sleeves 8, and a transverse baffle 7 is provided between the two limiting sleeves 8. The left and right ends of the transverse baffle 7 are fixed with latches, and the two latches are respectively inserted into the two limiting sleeves 8, so that the transverse baffle 7 can be disassembled. When the photovoltaic panel is placed on the movable plate 4, the installation of the transverse baffle 7 can protect the photovoltaic panel from the front side of the movable plate 4. The transverse baffle 7 is horizontally blocked in the middle position of the photovoltaic panel to prevent the photovoltaic panel from tipping forward.

[0046] The limiting sleeve 8 and the transverse baffle 7 are made of stainless steel or aluminum alloy.

[0047] In this embodiment, the lifting device also includes at least one foam partition plate for separating photovoltaic panels. When multiple photovoltaic panels are placed overlappingly on the movable plate 4 and lifted at the same time, a foam partition plate is laid between two adjacent overlapping photovoltaic panels. After the photovoltaic panels are lifted, when workers at a high place lift and unload the photovoltaic panels one by one from the movable plate 4, the surface of the photovoltaic panels can be avoided from being scratched under the protection of the foam partition plate.

[0048] The working principle and technical effects of the lifting device are as follows:

[0049] During the installation of solar photovoltaic panels, the lifting device can be used to lift the photovoltaic panels from the ground to a high place for workers on the suspended working platform to take them;

[0050] When using this lifting device to lift photovoltaic panels, multiple photovoltaic panels can be placed on top of each other on the movable plate 4, with foam partitions placed between adjacent photovoltaic panels for protection; the bottom baffle 6 at the bottom of the movable plate 4 supports the photovoltaic panels, and the side baffles 5 on the left and right sides of the movable plate 4 protect the photovoltaic panels from both sides. The cross baffles 7 are installed so that the cross baffles 7 protect the photovoltaic panels from the front to prevent the photovoltaic panels from falling during the lifting process;

[0051] The motor 15 is started, and the motor 15 drives the reel 16 to rotate to reel in the wire rope 18. As the wire rope 18 is reeled in, the movable plate 4 rises along the slope on the inclined support plate 3, thereby lifting the photovoltaic panel. The workers on the suspended working platform can easily lift the lifted photovoltaic panel to the bracket, which can save workers' physical strength and reduce the probability of the photovoltaic panel falling and breaking during the lifting process.

[0052] The lifting device can be pushed to move to adapt to the installation position of the photovoltaic panels, and multiple photovoltaic panels can be lifted at the same time to improve the lifting efficiency;

[0053] After all photovoltaic panels on the movable plate 4 are pulled onto the bracket, the motor 15 is started to control the reel 16 to unwind the wire rope 18. Under the action of the gravity of the movable plate 4, the movable plate 4 descends along the slope on the inclined support plate 3 to return to the low position for the next lifting of the photovoltaic panels.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein.
