Description

Technical Field

[0001] This utility model relates to the field of rotor inner tower lifting technology, specifically a wind-powered rotor inner tower lifting device. Background Technology

[0002] A wind-powered propulsion rotor is a type of ship wind-powered propulsion device with good energy efficiency, strong propulsion force, and small size. A typical wind-powered propulsion rotor consists of an outer cylinder and an inner tower. The inner tower is a tall, large circular cylindrical structure, usually manufactured in sections using a horizontal construction method. After the final assembly and painting are completed, the inner tower needs to be lifted from its horizontal position and converted to an upright position. During the process of converting the inner tower to an upright position, auxiliary devices such as lifting lugs are required for lifting.

[0003] The announcement number is CN217996531U, which discloses "a lifting device for the inner tower of a wind-powered rotor, the lifting device for the inner tower of a wind-powered rotor includes a base plate, a connecting beam and a plurality of lifting lugs, the base plate is provided with a plurality of first mating holes, the circumference of which is distributed is the same as the circumference of which is distributed on the mounting flange of the inner tower of the rotor, and the plurality of first mating holes and the plurality of first mounting holes can be aligned one by one, the connecting beam is connected to the base plate, and the plurality of lifting lugs are installed on the connecting beam";

[0004] There are still some drawbacks in its use. When lifting the inner tower after connecting it with flanges, the inner tower is in an inclined state. It is lifted by fixing it with multiple slings. The inclination angle of the multiple ropes is not consistent, which will cause some ropes to be in a taut state and some ropes to be in a slack state. The taut ropes are under more stress, resulting in different service lives for the two parts of the ropes. The taut ropes are prone to breakage, and it is not convenient to adjust the length of multiple ropes according to the inclination angle of the inner tower. Utility Model Content

[0005] The purpose of this invention is to provide a wind-powered rotor inner tower lifting device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A wind-powered rotor inner tower lifting device includes:

[0008] Connection components;

[0009] An adjustment component is provided at the upper end of the connecting component. The adjustment component includes a storage box. Multiple support frames are fixedly installed at equal angles inside the storage box. A winding drum is rotatably connected inside the support frame through a bearing. A rope is wound between two symmetrical winding drums. A motor capable of driving the winding drum to rotate is fixedly installed on the other side surface of the support frame.

[0010] Multiple limiting components are fixedly installed on one side surface of multiple support frames.

[0011] Furthermore, the connection component includes:

[0012] Flange;

[0013] The reinforcing frame is fixedly installed on one side of the flange surface.

[0014] Preferably, multiple No. 1 connecting rings are fixedly installed at equal angles on the upper surface of the reinforcing frame, and each of the multiple No. 1 connecting rings is rotatably connected to a rotating ring inside.

[0015] Furthermore, a second connecting ring is fixedly installed on the upper surface of the storage box, and multiple through holes are opened at equal angles on the outer surface of the storage box.

[0016] Preferably, the storage box has multiple fixing brackets fixedly installed at equal angles on its outer surface. The fixing brackets are symmetrically connected to pulleys inside. The rope moves through the through hole at the corresponding position and between the two pulleys, and is connected to the swivel ring.

[0017] Furthermore, the limiting component includes:

[0018] The limit plate is fixedly installed at one end of the winding drum;

[0019] The limiting frame is fixedly installed on one side surface of the support frame;

[0020] The T-shaped limit block is slidably connected inside the limit frame.

[0021] Preferably, an electric push rod is fixedly installed inside the limiting frame, the output end of the electric push rod is fixedly connected to the T-shaped limiting block, and multiple limiting grooves are opened at equal angles on the outer surface of the limiting plate, and the T-shaped limiting block is movably inserted into the limiting groove.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] 1. The motor at the corresponding position rotates the winding drum, causing the ropes wound around the outside of the two winding drums to rotate. By adjusting the length between the two symmetrical rope segments, the two ropes are wound around the outside of the winding drums. Driven by the motor, the winding drums move the ropes, allowing the ropes to be wound and unwound in different directions. Adjusting the rope length between the storage box and the No. 1 connecting ring ensures that multiple rope segments are taut when the inner tower is in an inclined state, distributing the force borne by a single rope segment and ensuring that the multiple rope segments are evenly stressed. This prevents the rope from breaking due to excessive stress on a single rope and also increases the service life of the ropes.

[0024] 2. After rope adjustment, the electric push rod extends, causing the T-shaped limit block to insert into the corresponding limit groove, fixing the limit plate and thus fixing the winding drum. This ensures that the rope is fixed after multiple length adjustments, preventing the rope from loosening due to the weight of the inner tower causing the winding drum to rotate, thereby improving the stability of the rope.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-5In this embodiment of the utility model, a wind-powered rotor inner tower lifting device includes a connecting component 1 and an adjusting component 2 disposed on the upper end of the connecting component 1. The adjusting component 2 includes a storage box 201, and multiple support frames 204 are fixedly installed at equal angles inside the storage box 201. A winding drum 205 is rotatably connected inside the support frame 204 through a bearing. A rope 208 is wound between two symmetrical winding drums 205. A motor 209 capable of driving the winding drum 205 to rotate is fixedly installed on the other side surface of the support frame 204. Multiple limiting components 3 are respectively fixedly installed on one side surface of multiple support frames 204.

[0033] Specifically, the connecting component 1 is used to connect the inner tower, the length of the multi-segment rope 208 is adjusted by the adjusting component 2, and the stability of the rope 208 after adjustment is improved by the limiting component 3.

[0034] Example 1

[0035] like Figure 1 and Figure 2 As shown, in this embodiment, the connecting component 1 includes a flange 101, and a reinforcing frame 102 is fixedly installed on one side surface of the flange 101; a plurality of first connecting rings 103 are fixedly installed at equal angles on the upper surface of the reinforcing frame 102, and a rotating ring 104 is rotatably connected inside each of the plurality of first connecting rings 103.

[0036] In this embodiment, the flange 101 and the inner tower are connected by bolts, and the swivel ring 104 is rotated to connect with the first connecting ring 103, which reduces the repeated wear between the rope 208 and the first connecting ring 103 after the rope is lifted due to the change in angle.

[0037] like Figure 3 and Figure 4 As shown, in this embodiment, a second connecting ring 202 is fixedly installed on the upper surface of the storage box 201, and multiple through holes 203 are opened at equal angles on the outer surface of the storage box 201; multiple fixing brackets 206 are fixedly installed at equal angles on the outer surface of the storage box 201, and pulleys 207 are symmetrically rotatably connected inside the fixing brackets 206. The rope 208 moves through the through holes 203 at the corresponding positions and between the two pulleys 207, and is connected to the rotating ring 104.

[0038] In practice, two pulleys 207 clamp the rope 208 to reduce wear between the rope 208 and the storage box 201. The motor 209 at the corresponding position operates, causing the winding drum 205 to rotate, which in turn rotates the rope 208 wound around the outside of the two winding drums 205, allowing one end to be released and the other end to be wound up. The length between the two symmetrical rope segments 208 is adjusted, so that the two ropes 208 are wound around the outside of the winding drum 205. Driven by the motor 209, the winding drum 205 moves the rope 208, causing the rope 208 to be released and wound in different directions. The length of the rope 208 between the storage box 201 and the first connecting ring 103 is adjusted. When the inner tower is in an inclined state, all rope segments 208 are kept taut, distributing the force borne by a single rope segment 208, so that the multiple rope segments 208 are evenly stressed, avoiding the rope 208 from breaking due to excessive stress on a single rope segment, and improving the service life of the rope 208.

[0039] Example 2

[0040] Based on Example 1, in order to compensate for the poor stability of rope 208 after adjustment.

[0041] like Figure 5 As shown, in this embodiment, the limiting component 3 includes: a limiting disk 301 fixedly installed at one end of the winding drum 205, a limiting frame 303 fixedly installed on one side surface of the support frame 204, and a T-shaped limiting block 305 slidably connected inside the limiting frame 303; an electric push rod 304 is fixedly installed inside the limiting frame 303, the output end of the electric push rod 304 is fixedly connected to the T-shaped limiting block 305, and multiple limiting grooves 302 are opened at equal angles on the outer surface of the limiting disk 301, and the T-shaped limiting block 305 is movably inserted into the limiting groove 302.

[0042] In practice, after the rope 208 is adjusted, the electric push rod 304 extends, pushing the T-shaped limit block 305 upward, so that the T-shaped limit block 305 is inserted into the limit groove 302 at the corresponding position, fixing the limit plate 301, thereby fixing the winding drum 205, and fixing the rope 208 after multiple length adjustments, preventing the rope 208 from loosening due to the gravity of the inner tower causing the winding drum 205 to rotate, thus improving the stability of the rope 208.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0044] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
