DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] like Figures 1 to 7 As shown, the photovoltaic module lifting device includes a vertical ladder frame 1, a hoist 2 and a conveying frame 3. The vertical ladder frame 1 is used to be erected on the wall of a building, and the hoist 2 is arranged at the lower part of the vertical ladder frame 1. Specifically, a base 4 can be installed at the bottom of the vertical ladder frame 1, and the hoist 2 is installed on the base 4. The conveying frame 3 is slidably arranged on the vertical ladder frame 1, and a pulley 5 is arranged on the top of the vertical ladder frame 1. The traction rope 6 on the hoist 2 bypasses the pulley 5 and is connected to the conveying frame 3. The hoist 2 is used to drive the conveying frame 3 to slide up and down along the vertical ladder frame 1 to realize the transportation of the photovoltaic module 7 from the ground to the roof.

[0024] Figure 1-Figure 5 As shown, the vertical ladder frame 1 includes a first vertical ladder portion 11 and a second vertical ladder portion 12. The rear side of the first vertical ladder portion 11 and the rear side of the second vertical ladder portion 12 are hinged by a first hinge 8, so that the first vertical ladder portion 11 and the second vertical ladder portion 12 can be relatively flipped and folded, so as to facilitate storage and carrying. At the same time, the front side of the first vertical ladder portion 11 and the front side of the second vertical ladder portion 12 are also provided with buckles 13. When erecting, the second vertical ladder portion 12 is unfolded and fixed to the first vertical ladder portion 11 through the buckles 13, thereby ensuring the stability of the vertical ladder frame 1 when in use.

[0025] Figure 6 and Figure 7 As shown, the conveying frame 3 includes a sliding frame 31 and a supporting frame 32, and the sliding frame 31 is fixedly connected to the supporting frame 32. The sliding frame 31 is used to be slidably connected to the vertical ladder frame 1 and realize the overall up and down sliding, and the supporting frame 32 is used to support and convey the photovoltaic module 7.

[0026] The sliding frame 31 is rectangular in shape as a whole, and a group of first rollers 311 and second rollers 312 are respectively installed at its four corners. The first rollers 311 are used to roll and abut against the front side of the vertical ladder frame 1, and the second rollers 312 are used to roll and abut against the rear side of the vertical ladder frame 1 to reduce the friction resistance during the sliding process. A first hook 313 is also provided on the top of the sliding frame 31, and the first hook 313 is connected to the traction rope 6, so as to control the lifting and lowering of the conveying frame 3 through the winch 2.

[0027] The bottom of the support frame 32 is provided with a support column 321, which can prop up the photovoltaic assembly 7 during the lifting process to prevent the photovoltaic assembly 7 from being damaged by friction with the vertical ladder frame 1. At the same time, the top of the support frame 32 is higher than the sliding frame 31, and the support frame 32 and the top of the sliding frame 31 are hinged by the second hinge 9, so that the support frame 32 can be flipped relative to the sliding frame 31, thereby facilitating the installation and unloading of the photovoltaic assembly 7.

[0028] Furthermore, two second hooks 33 are spaced apart on the top of the conveying frame 3, and the photovoltaic assembly 7 is fixed to the conveying frame 3 by means of a cable to prevent the photovoltaic assembly 7 from slipping or shifting during the lifting process, thereby improving the safety and stability of the conveying.

[0029] When in use, the vertical ladder frame 1 is first erected on the wall and fixed, and then the photovoltaic module 7 is placed on the supporting frame 32 and fixed to the second hook 33 through the guard cable 8. Then the winch 2 is started, and the sliding frame 31 is pulled upward along the vertical ladder frame 1 through the traction cable 6, so as to transport the photovoltaic module 7 to the roof for installation.

[0030] Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the protection scope of the utility model.
