[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Reference Figure 1-Figure 5 The utility model provides a hoisting tool with an offshore photovoltaic overall structure tilt adjustment function, comprising:

[0027] A hoisting platform assembly, the upper portion of which is connected to the lifting equipment;

[0028] Two sets of adjustable hoisting components, the two sets of adjustable hoisting components are respectively arranged on the same side of the hoisting platform component, the adjustable hoisting component includes a fixed pulley 7 rotatably connected to the hoisting platform component and a lifting actuator arranged at the end of the hoisting platform component, the lifting actuator is connected to the photovoltaic overall structure, the adjustable hoisting component also includes a winch 6 arranged on the hoisting platform component, the winch 6 is located between the fixed pulley 7 and the lifting actuator, and the wire rope on the winch 6 passes around the fixed pulley 7 and is transmission-connected to the lifting actuator;

[0029] Two groups of fixed hoisting components are respectively arranged on one side of the hoisting platform component away from the lifting actuator, and the two groups of fixed hoisting components are fixedly connected to the photovoltaic overall structure.

[0030] The main function of the fixed pulley 7 is to reverse the connection direction of the wire rope on the winch 6 to ensure the angle of the rope entry and make the rope arrangement more uniform; the main function of the lifting actuator is to adjust the distance between one side of the photovoltaic structure and the lifting platform assembly, thereby adjusting the inclination angle of the photovoltaic structure; the main function of the winch 6 is to provide power for the lifting action of the lifting actuator; the main function of the fixed lifting assembly is to lift the other side of the photovoltaic structure. On the whole, the utility model achieves the effect of tilting the offshore photovoltaic structure at a certain angle after lifting by adjusting one side of the photovoltaic structure up and down through the lifting actuator. At the same time, through the setting of the fixed pulley, the winch can be closer to the end of the lifting platform assembly, reducing the force on the lifting platform assembly, and through the circumferential effect of the fixed pulley on the direction of the wire rope, the rope entry angle is ensured while the rope arrangement is also more uniform.

[0031] To further optimize the solution, the lifting actuator includes a fixed pulley 8 fixedly connected to the lifting platform assembly, a movable pulley 9 is arranged below the fixed pulley 8, the wire rope on the winch 6 passes around the fixed pulley 7 and is then connected between the fixed pulley 8 and the movable pulley 9, and the movable pulley 9 is connected to the photovoltaic overall structure through the lower short sling 5.

[0032] like Figure 2 As shown, the wire rope of the winch 6 passes around the fixed pulley 7 from the inside and is repeatedly wound between the fixed pulley 8 and the movable pulley 9 to form a pulley group. When the winch 6 reels the wire rope, the pulley group composed of the fixed pulley 8 and the movable pulley 9 will drive the movable pulley 9 to rise, thereby driving the photovoltaic overall structure and the side connected to the movable pulley 9 to rise together, thereby achieving the inclination adjustment of the photovoltaic overall structure.

[0033] The fixed block 8 and the movable block 9 use an 8-fold pulley group, which can greatly reduce the specifications of the winch 6. By reducing the specifications of the winch 6, the load during hoisting and the pressure of the hoisting platform components can be reduced.

[0034] According to a further optimized solution, the fixed lifting assembly includes a lower long lifting strap 4, the top end of the lower long lifting strap 4 is fixedly connected to the lifting platform assembly, and the bottom end of the lower long lifting strap 4 is connected to the photovoltaic overall structure.

[0035] like Figure 1 As shown, the bottom ends of the lower long sling 4 and the lower short sling 5 are connected to the fixing points on the photovoltaic integral assembly through shackles respectively.

[0036] According to a further optimized solution, the lifting platform assembly includes two groups of parallel arranged cross beam sections 1 and two groups of parallel arranged longitudinal beam sections 2, and both ends of the two groups of cross beam sections 1 are fixedly connected to one end of the two groups of longitudinal beam sections 2 through connecting pieces.

[0037] A further optimized solution is that the fixed pulley 8, winch 6 and fixed pulley 7 are arranged on the same beam section 1, the lower long sling 4 is fixedly connected to another beam section 1, the fixed pulley 8 is fixedly connected to the end of the beam section 1, the winch 6 is fixedly connected near the end of the beam section 1, the fixed pulley 7 is rotatably connected to the beam section 1, and the fixed pulley 7 is arranged on the side of the winch 6 away from the fixed pulley 8.

[0038] like Figure 1 and Figure 2 As shown, the winch 6 is arranged close to the lifting point of the beam section 1, that is, close to the fixed pulley 8, which can reduce the overall force of the lifting device.

[0039] Two groups of pulley groups consisting of two groups of fixed pulleys 8 and movable pulleys 9 are arranged on both sides of the same beam section 1, and are connected to one side of the photovoltaic overall structure through the lower short sling 5. Two groups of lower long slings 4 are arranged on both sides of the other beam section 1 to connect the other side of the photovoltaic overall structure. By fixing one side of the photovoltaic overall structure and adjusting the height of the other side of the photovoltaic overall structure, the inclination angle of the photovoltaic overall structure can be adjusted.

[0040] According to a further optimized solution, the cross beam section 1 and the longitudinal beam section 2 are respectively formed by splicing a plurality of truss structures.

[0041] like Figure 1 As shown, the cross beam section 1 is composed of 5 trusses, and the longitudinal beam section 2 is composed of two trusses. The truss structure can not only provide sufficient strength, but also reduce the weight of the cross beam section 1 and the longitudinal beam section 2, thereby improving the lifting efficiency.

[0042] According to a further optimization scheme, the cross-section of the rotating rod on the cross-beam section 1 and the longitudinal beam section 2 is rectangular, and the long sides of the cross-sectional rectangle of the rotating rod on the cross-beam section 1 and the longitudinal beam section 2 are arranged horizontally.

[0043] like Figure 3 As shown, by setting the cross-section of all chords on the cross-beam segment 1 and the longitudinal beam segment 2 to a rectangle and arranging them horizontally, the bending section modulus can be increased under the same area, and at the same time, the length change of each diagonal rod in the cross-beam segment 1 and the longitudinal beam segment 2 can be minimized, thereby improving the horizontal stability of the cross-beam segment 1 and the longitudinal beam segment 2.

[0044] According to a further optimized solution, the connecting member includes a connecting ear 10 fixedly connected to the end of the longitudinal beam section 2 and a hanging fork 11 hinged to the end of the cross beam section 1 , and the connecting ear 10 and the hanging fork 11 are fixedly connected via a connecting pin 12 .

[0045] like Figure 5As shown, a slot for the connecting ear 10 to be inserted is provided on the lifting fork 11, and openings for the connecting pin 12 to pass through are respectively provided on the lifting fork 11 and the connecting ear 10. When the connecting ear 10 on the longitudinal beam section 2 is inserted into the slot, and the opening on the connecting ear 10 is aligned with the opening on the lifting fork 11, the connecting pin 12 is inserted, so that the connecting ear 10 is fixedly connected to the lifting fork 11, and the connection between the cross beam section 1 and the longitudinal beam section 2 is realized.

[0046] According to a further optimized solution, two ends of the two groups of longitudinal beam sections 2 are respectively fixedly connected with one end of the upper sling 3, and the other ends of the four groups of upper slings 3 are respectively connected with the lifting equipment.

[0047] like Figure 1 As shown, there are four upper slings 3, which are mainly used to connect the hook head of the lifting equipment and the sling of the utility model, and can be adapted to single-hook lifting equipment and double-hook lifting equipment.

[0048] The working process of this embodiment is as follows: before use, connect the lifting fork 11 on the crossbeam section 1 and the connecting ear 10 on the outer longitudinal beam section 2 through the connecting pin 12, assemble the sling, and connect the lower long sling 4 and the lower short sling 5 to the corresponding crossbeam section 1 and the movable pulley 9 respectively. The retracting winch 6 allows the movable pulley 9 to move up and down, and adjusts the lower long sling 4 and the lower short sling 5 to a flush state at the bottom end. The lower long sling 4 and the lower short sling 5 are connected to the lifting point of the offshore photovoltaic integral structure through the shackle. The sling and the photovoltaic integral structure are lifted horizontally by the lifting equipment. After lifting to a certain height, the winch 6 is controlled to release the wire rope to move the movable pulley 9 downward so that the offshore photovoltaic integral structure is tilted at a certain angle. After tilting to the specified angle, the photovoltaic integral structure can be conveniently fixed to the designed position. Due to the change in the center of gravity, each component of the utility model has a certain angle of deflection, and the maximum angle of deflection is no more than 5 degrees, which has little effect on the strength of each component in the utility model. Before and after the action, as shown in Figure 3 shown.

[0049] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0050] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
