The hand-operated hoist is installed on the lifting rope at the lower end of the photovoltaic panel. Considering the balance, at least two construction workers need to operate the hand-operated hoist simultaneously to adjust the inclination angle of the photovoltaic panel until it is installed on the photovoltaic panel fixing frame. The entire process requires multiple people to cooperate multiple times to complete, and the convenience needs to be improved. Therefore, a lifting device for hoisting photovoltaic panels during installation is needed. SUMMARY

[0021] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0022] Referring to Figures 1-3 The utility model discloses a photovoltaic panel installation hoisting device, including first frame body 1 and with first frame body 1 side -by -side second frame body 2, first frame body 1, second frame body 2 are square frame structure, also can be other shape's frame structure, but considering the current photovoltaic panel is mainly rectangular, and the operator also needs certain operating space when installing photovoltaic panel, therefore the first frame body 1 and second frame body 2 in the application select the frame structure close to square, and the inner wall height of first frame body 1 and second frame body 2 is slightly greater than the height of the photovoltaic panel to be installed, and the inner wall width of first frame body 1 and second frame body 2 is obviously greater than the width of the photovoltaic panel to be installed, so that the worker can operate from the interval between first frame body 1 and second frame body 2 on the left and right sides of the photovoltaic panel when needing to hand photovoltaic panel and install, and it is more in line with the installation process needs of photovoltaic panel.

[0023] The top of first frame body 1 is welded with lifting ring 3, lifting ring 3 has two, two lifting rings 3 are arranged along the width direction of first frame body 1, when using, the lifting hooks of the crane are respectively hooked on two lifting rings 3, or the lifting ropes are respectively bound on lifting ring 3, and first frame body 1 is lifted by two hooks or lifting ropes, to reduce the rotation risk of the device in the lifting process in the horizontal direction.

[0024] The bottom of first frame body 1 is hinged with second frame body 2, and a telescopic piece 5 is installed between first frame body 1 and second frame body 2. The telescopic piece 5 is selected as an electric cylinder to drive first frame body 1 and second frame body 2 to open or fold. When the telescopic piece 5 is extended, first frame body 1 and second frame body 2 rotate around the hinge position as the center. The top ends of first frame body 1 and second frame body 2 move away from each other to perform an opening action. When the telescopic piece 5 is shortened, first frame body 1 and second frame body 2 rotate around the hinge position as the center. The top ends of first frame body 1 and second frame body 2 move closer to each other to perform a folding action.

[0025] A clamping piece 4 for clamping the photovoltaic panel is installed on second frame body 2. When in use, the photovoltaic panel is clamped and fixed on second frame body 2 by the clamping piece 4. The device is lifted by first frame body 1. Then the telescopic piece 5 is controlled to drive second frame body 2 to rotate and tilt. The device is tilted to the required angle for installation, replacing the combination of lifting ropes and hand-operated hoists in the traditional installation method, and improving the convenience of photovoltaic panel installation.

[0026] The bottom of the first frame body 1 is provided with a hinge 7, and the first frame body 1 and the second frame body 2 are rotatably connected through the hinge 7. When the first frame body 1 and the second frame body 2 rotate around the hinge 7, the center of gravity of the whole device deviates to the direction in which the second frame body 2 rotates. For example, if the direction in which the second frame body 2 rotates is the right side, as the rotation angle of the second frame body 2 increases, the center of gravity of the whole device deviates to the right and downward. When the first frame body 1 and the second frame body 2 are attached together, the whole device is in a state close to vertical, slightly tilted to the side of the second frame body 2. When the second frame body 2 and the photovoltaic panel rotate to the right side, the whole device will deviate to a larger angle, so that the actual rotation angle of the second frame body 2 is greater than the angle between the second frame body 2 and the first frame body 1.

[0027] The side surfaces of the first frame body 1 and the second frame body 2 are provided with telescopic members 5, the two ends of the telescopic members 5 are rotatably connected with the first frame body 1 and the second frame body 2 respectively, and the telescopic members 5 are installed on the side surfaces of the first frame body 1 and the second frame body 2 near the middle. Specifically, the fixed end of the telescopic member 5 is connected with the lower part of the side wall of the first frame body 1 through a rotating shaft, and the telescopic end of the telescopic member 5 is connected with the upper part of the side wall of the second frame body 2 through a rotating shaft. When the telescopic member 5 is elongated or shortened, it drives the second frame body 2 to rotate around the hinge 7.

[0028] The clamping member 4 includes two baffles 6 welded to the inner side of the second frame body 2, and the two baffles 6 are respectively located at one end of the inner side of the second frame body 2 close to the first frame body 1. When it is necessary to fix the photovoltaic panel in the second frame body 2, the top end and the bottom end of the photovoltaic panel are blocked by the two baffles 6 respectively, so as to prevent the photovoltaic panel from entering the first frame body 1.

[0029] The end surface of the second frame body 2 away from the first frame body 1 is provided with a clamping block 401 and a clamping bolt 402, the clamping bolt 402 penetrates the clamping block 401, and the clamping bolt 402 is screwed with the second frame body 2. Here, the thickness of the second frame body 2 is slightly smaller than the thickness of the photovoltaic panel, so that the clamping block 401 can play a role. First, the clamping block 401 is disassembled or adjusted to a position that does not block the photovoltaic panel, then the photovoltaic panel is placed into the second frame body 2 and abuts against the baffle 6, and then the clamping block 401 is adjusted again to clamp the photovoltaic panel, and the clamping bolt 402 is tightened again to clamp the photovoltaic panel through the clamping block 401.

[0030] The bottom of the first frame body 1 is welded with a pull ring 8, and the pull ring 8 has two pull rings 8 respectively located at both ends of the bottom of the first frame body 1. During the hoisting of the photovoltaic panel, a pull rope can also be used to pass through the pull ring 8 to assist in hoisting work. First, it prevents the device and the photovoltaic panel from rotating obviously in the horizontal direction during hoisting, and second, it assists the device and the photovoltaic panel to be accurately hoisted to the specified installation position.

[0031] Working principle: when using, the hook of the crane is hung on the lifting ring 3, the device is lifted through the first frame body 1, then the photovoltaic panel to be installed is clamped and fixed in the inner side of the second frame body 2 through the clamping piece 4, after the photovoltaic panel is lifted above the designated installation position, the telescopic piece 5 is controlled to be elongated, so that the first frame body 1 and the second frame body 2 are opened, at this time, due to the change of the center of gravity of the device and the photovoltaic panel, the posture of the device and the photovoltaic panel as a whole also changes correspondingly, the construction personnel visually measure the change of the inclination angle, when the inclination angle approaches the installation requirement, the device and the photovoltaic panel are directly placed on the photovoltaic panel fixing frame through the crane, the construction personnel loosen the clamping piece 4, the device is removed through the crane, then the construction worker fixes the photovoltaic panel.
