[0021] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0022] This embodiment provides a technical solution: an auxiliary hoisting device for offshore photovoltaic support structures, such as... Figure 1-3 As shown, the system includes a main hanger 1 and an adjustable lifting assembly 2 located at the bottom of the main hanger 1. A lifting lug 3 is fixed to the top of the main hanger 1. The adjustable lifting assembly 2 includes a telescopic component and an extension / retraction component. The telescopic component and extension / retraction component work together to change the lifting range that the lifting equipment can lift. The telescopic component includes a fixed plate 21, with cylindrical sleeves 22 fixed to both sides of the fixed plate 21. Two inner grooves 23 are formed on the inner side of the fixed plate 21, and a first hydraulic cylinder 24 is fixed to the inner side of each of the two inner grooves 23. The two cylindrical sleeves... Two double-rod mounting brackets 25 slide between the cylinders 22. Each double-rod mounting bracket 25 includes a plate 251 and two rods 252 fixed to the outer surface of the plate 251. The two rods 252 slide through the inner sides of the two cylindrical sleeves 22 respectively. One end of the telescopic rod of the first hydraulic cylinder 24 is fixedly connected to the plate 251. Both cylindrical sleeves 22 are fixed to the bottom of the main hanger 1. Through holes 26 are provided on the plate 251 and the fixed plate 21 of the two double-rod mounting brackets 25.

[0023] The expansion component includes a first double mounting plate 27 fixed to the bottom of the fixed plate 21 and two second double mounting plates 28. The two second double mounting plates 28 are respectively fixed to the bottom of the plate body 251 of the two double rod mounting frames 25. Hook rotating arms 29 are rotatably mounted on both sides of the first double mounting plate 27 and both sides of the two second double mounting plates 28.

[0024] The expansion assembly also includes two slide rails 211 fixed to the outer surface of the hook rotating arm 29, a connecting plate 212 disposed between the two slide rails 211, and a second hydraulic cylinder 210. Each hook rotating arm 29 has two symmetrically arranged slide rails 211 fixed on its front and back. Each slide rail 211 has a connecting shaft 213 sliding on its inner side. The two connecting shafts 214 disposed on the two left and right opposite hook rotating arms 29 are fixedly connected to the same connecting plate 213. Three second hydraulic cylinders 210 are provided. Two of the second hydraulic cylinders 210 are fixed to the top of the plate 251 in the two double rod mounting brackets 25, and the other second hydraulic cylinder 210 is fixed to the top of the fixing plate 21. One end of the second hydraulic cylinder 210 passes through the through hole 26 and is fixed to the top of the connecting plate 212.

[0025] In use: The crane lifts the main gantry 1, and the main gantry 1 lifts the adjustment assembly 2 and the photovoltaic bracket lifted by the hook rotating arm 29 in the adjustment assembly 2 and moves it to the installation position. Before the adjustment assembly 2 is used, the size of the hook rotating arm 29 can be adjusted according to the size of the photovoltaic bracket to be lifted, so as to be suitable for photovoltaic brackets of various sizes. The extension of the telescopic rod of the first hydraulic cylinder 24 drives the plate 251 in the double rod mounting frame 25 connected to it away from the fixed plate 21. The two rods 252 will slide out from the cylindrical sleeve 22 respectively, thereby increasing the distance between the expansion parts on the two double rod mounting frames 25 and the expansion parts on the fixed plate 21. The retraction of the telescopic rod of the first hydraulic cylinder 24 drives the plate 251 closer to the fixed plate 21. The two rods 252 will slide into the two cylindrical sleeves 22 respectively, thereby decreasing the distance between the expansion parts on the two double rod mounting frames 25 and the expansion parts on the fixed plate 21.

[0026] The extension rod of the second hydraulic cylinder 210 pushes the connecting plate 212 downward, causing the connecting shaft 213 connected to it to slide in the slide rail 211. When the connecting plate 212 moves the connecting shaft 213 upward, the two hook rotating arms 29 on both sides of the connecting plate 212 will deflect away from each other to increase the distance between them and expand the lifting size. When the connecting plate 212 moves the connecting shaft 213 downward, the two hook rotating arms 29 on both sides of the connecting plate 212 will deflect closer to each other to decrease the distance between them and reduce the lifting size.

[0027] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
