Description

Technical Field

[0001] The invention relates to the technical field of wind power generation equipment, in particular to a special hanger for installing wind power generation equipment. Background Art

[0002] Wind power generation is a renewable energy technology that converts wind energy into electrical energy. Wind power generation equipment is gradually being widely used around the world to reduce dependence on fossil energy and reduce greenhouse gas emissions. Wind power generation equipment is mainly composed of blades, hubs, tower top equipment (including gearboxes and generators, etc.) and towers. When assembling wind power generation equipment, it is first necessary to pour the foundation at the designated location and assemble the tower, then hoist the tower top equipment to the top of the tower, then hoist the blades to the hub on the ground, and finally hoist the hub and blades to the tower top equipment and connect them.

[0003] At present, the hoisting process of the above-mentioned blades and hubs is mainly carried out by external lifting equipment (such as a crane) with manual assistance. During the hoisting process of the blades and the hub, the blades are mainly adjusted manually and aligned with the hub, and then the two are connected and installed. It is difficult to ensure the accuracy of the hub and blade docking through manual alignment. The installation error is large during the whole process. In addition, due to the large mass of the blades and the difficulty in operation, it is easy to cause the blades and the hub to collide due to misalignment due to inaccurate manual guidance during the hoisting process, which in turn causes damage to the blades or the hub, affecting the normal use of the subsequent wind power generation equipment.

[0036] like Figure 1 , Figure 2 and Figure 4 As shown, the guide unit 83 includes a fixed block 830, and the lower end surface of the sliding plate 80 is provided with a fixed block 830 for sliding up and down through a connecting column. Two U-shaped frames 831 distributed left and right and with openings facing downward are provided on the right side of the fixed block 830, and the left U-shaped frame 831 is fixedly connected to the fixed block 830, and the two vertical sections of the left U-shaped frame 831 are fixedly provided with a reference column 832 whose axis extends from left to right and slides through the vertical section of the right U-shaped frame 831, and the horizontal section and the two vertical sections of the U-shaped frame 831 are provided with threaded rods 833, and the adjacent end surfaces of the three threaded rods 833 on the same U-shaped frame 831 are fixedly provided with arc plates 834, and a driving group 84 is provided on the U-shaped frame 831.

[0037] During operation, the wheel hub is first lifted by an external lifting device and placed on the supporting plate 3, and then the wheel hub is clamped by the fixing unit 4, and the axis of the wheel hub is made to be colinear with the axis of the supporting plate 3, and the external lifting device installs the suspension plate 7 to the base plate 5 through two circular columns 6, and then the external lifting device lifts the blades to be installed in the required position through the lifting unit 82, and makes the two U-shaped frames 831 respectively located on the wheel hub and the blades, and the external lifting device drives the blades to continue to approach the wheel hub, and the guide unit 83 limits and fixes the wheel hub, and guides the wheel hub and the blades to dock through multiple guiding processes, and then the staff fixes the blades to the wheel hub, and rotates the base plate 5 after completing the installation of a single blade, and the base plate 5 drives the suspension plate 7 and the lifting unit 82 thereon to rotate synchronously to the next installation position, and repeats the above operations to complete the installation of the remaining blades. After completing the installation of all blades, the external lifting device lifts the wheel hub and the blades as a whole to the tower top equipment to complete the installation operation.

[0038] like Figure 1 , Figure 2 and Figure 4 As shown, the driving group 84 includes an L-shaped plate 840, and the end surfaces of the vertical section and the horizontal section of the U-shaped frame 831 away from the arc-shaped plate 834 are fixedly provided with the L-shaped plate 840, and a section of the L-shaped plate 840 parallel to the U-shaped frame 831 slides through a rotating shaft 841 coaxial with the corresponding threaded rod 833, and the rotating shaft 841 slides through the corresponding threaded rod 833, and the threaded rod 833 is threadedly matched with the corresponding U-shaped frame 831, and a sliding rod 842 that slides through the U-shaped frame 831 is fixedly provided on the arc-shaped plate 834.

[0039] like Figure 1 and Figure 4As shown, the drive group 84 also includes a lateral block 843, and two front-to-rear symmetrical lateral blocks 843 are fixedly provided on the upper end surface of the upper L-shaped plate 840, and a transmission shaft 844 with an axis extending from front to rear is rotatably provided on the lateral block 843, and adjacent ends of the transmission shaft 844 and the upper rotating shaft 841 are fixedly provided with bevel gears 845, and the two adjacent bevel gears 845 are meshed with each other, and sprockets 846 are fixedly sleeved on the transmission shaft 844 and the lower rotating shaft 841, and the two upper and lower opposite sprockets 846 are connected by a chain, and the front transmission shaft 844 is connected to an external motor, and the external motors are all high-torque motors.

[0040] During operation, after the blade is lifted by the lifting unit 82 and moved to a position close to the docking position with the hub, the staff moves the two U-shaped frames 831 so that the two U-shaped frames 831 drive the arc-shaped plates 834 thereon to move to the hub and the blade respectively, and the U-shaped openings of the U-shaped frames 831 face the two (see Figure 4 ), the interface of the hub and the docking point of the blades are both cylindrical, and the external motor drives the front transmission shaft 844 to rotate synchronously, and the transmission shaft 844 drives the sprocket 846 thereon to rotate synchronously, and the transmission cooperation between the sprocket 846 and the chain makes the front rotating shaft 841 rotate synchronously, and at the same time, the transmission shaft 844 drives the bevel gear 845 thereon to rotate synchronously, and through the meshing between the bevel gear 845 and the corresponding intermediate bevel gear 845 and the meshing between the intermediate bevel gear 845 and the rear bevel gear 845, the intermediate bevel gear 845 and the rear bevel gear 845 both rotate, and the rear bevel gear 845 drives the transmission shaft 844 thereon to rotate synchronously, and through the cooperation between the corresponding sprocket 846 and the chain, the rear rotating shaft 841 rotates synchronously, and the intermediate bevel gear 845 drives the rotating shaft 841 thereon. The U-shaped frame 831 is rotated, so all the rotating shafts 841 drive the threaded rods 833 thereon to rotate synchronously. Through the threaded cooperation between the threaded rods 833 and the U-shaped frame 831, the threaded rods 833 drive the arc plates 834 thereon to move toward each other. Finally, the three arc plates 834 on the left U-shaped frame 831 are pressed against the hub interface, and the three arc plates 834 on the right U-shaped frame 831 are pressed against the docking of the blades, so that the U-shaped frame 831 is adaptively moved in the center according to the axis of the hub interface or the axis of the docking of the blades. The two U-shaped frames 831 are adaptively moved and adjusted according to the hub or the blades, respectively, to facilitate the subsequent guidance of the docking of the two. Since the right U-shaped frame 831 is slidably set on the reference column 832 of the left U-shaped frame 831, the hub interface and the blade docking can be aligned in the end, so as to achieve a one-time guidance alignment of the two. The guiding unit 83 moves up after the blade docking is completed to avoid the blades.

[0041] like Figure 2 and Figure 3As shown, the hoisting unit 82 includes a rotating plate 820, and the lower end surface of the hoisting plate 81 is rotatably provided with the rotating plate 820 through a rotating axis with a vertical axis, and the lower end surface of the rotating plate 820 is fixedly provided with two L-shaped frames 821 distributed on the left and right, and the lower end surface of the horizontal section of the L-shaped frame 821 is provided with a wire rope 822 for hoisting the blades, and the guide unit 83 also includes a guide group 85, and a guide group 85 is commonly provided between the hoisting plate 81 and the suspension plate 7, and the guide group 85 includes a guide rod 851 for guiding the movement of the hoisting plate 81 and the blades and a guide block 852 that cooperates with the guide rod 851.

[0042] like Figure 2 and Figure 3 As shown, the guide group 85 also includes a square block 850, and two front-to-rear symmetrical square blocks 850 are fixedly provided on the upper end surface of the lifting plate 81, and a guide rod 851 with a horizontal axis is fixedly provided on the left end surface of the square block 850, and a guide block 852 corresponding to the guide rod 851 is fixedly provided on the upper end surface of the suspension plate 7, and a limiting groove 853 with an axis extending from left to right is provided on the left end surface of the guide block 852.

[0043] like Figure 3 As shown, the guide group 85 also includes a guide groove 854. The right end face of the guide block 852 is provided with a guide groove 854 with a small diameter end facing left and in a truncated cone shape. The axis of the guide groove 854 is colinear with the axis of the limiting groove 853 and the two are connected. The upper end face of the guide block 852 is provided with a guide groove 855 connected to the guide groove 854.

[0044] During operation, first, the lifting plate 81 is moved to the top of the blade by the external lifting equipment, and then the wire rope 822 is manually tied to the blade. The external lifting equipment lifts the blade and makes the lifting plate 81 drive the blade close to the suspension plate 7. During the movement of the lifting plate 81, the height of the lifting plate 81 is adjusted so that the guide rod 1 851 on the lifting plate 81 enters the guide groove 1 854 from the guide groove 2 855, and then continues to move to the left close to the suspension plate 7, and the guide rod 1 851 is stuck in the corresponding limit groove 853. The two guide rods 1 851 are guided to limit and guide the process of the lifting plate 81 driving the blade to move, which is convenient for subsequent precise alignment, that is, the hub and the blade are guided and aligned once. Secondly, in this process, the guide groove 1 854 and the guide groove 2 855 guide the movement of the guide rod 1 851, which is convenient for the staff to operate the external lifting equipment to make the guide rod 1 851 move to the corresponding limit groove 853, thereby reducing the difficulty of the overall lifting process and facilitating operation.

[0045] In the process of guiding the blades to align with the hub, the rotating plate 820 adaptively drives the blades to rotate, which facilitates the alignment of the blades with the hub, solving the problem of manually pulling the blades to adjust the angle or adjusting the angle through external lifting equipment during traditional lifting processes, thereby reducing the difficulty of the lifting process.

[0046] like Figure 4 As shown, all the arc plates 834 are commonly provided with a guide group 2, and the guide group 2 includes a guide rod 2 86. The right end surface of the left arc plate 834 is fixedly provided with a guide rod 2 86, and the right arc plate 834 is provided with a guide groove 3 that cooperates with the guide rod 2 86. The left end portion of the inner wall of the guide groove 3 is chamfered, and the right end of the guide rod 2 86 is chamfered.

[0047] After the two U-shaped frames 831 are adaptively adjusted according to the positions of the hub interface and the blade docking point, the guide rod 1 851 is located in the corresponding limit groove 853, and then the external lifting equipment works to make the lifting plate 81 drive the blade to move left close to the hub, and the right U-shaped frame 831 synchronously moves close to the left U-shaped frame 831. In the above process, the hub interface and the blade docking point are guided and aligned by inserting the guide rod 2 86 into the corresponding guide groove 3 to ensure that the two can be accurately installed.

[0048] It should be noted that during the lifting process of the blades, the first preliminary guiding alignment between the blades and the hub is performed through the cooperation between the guide rod 1 851 and the corresponding limit groove 853 to facilitate subsequent installation operations. After the U-shaped frame 831 adaptively adjusts its position according to the clamping of the arc plate 834, the right U-shaped frame 831 moves leftward and approaches the left U-shaped frame 831, and the blades and the hub are guided and aligned for the second time. Finally, the guide rod 2 86 is inserted into the corresponding guide groove 3 to guide the hub and the blades for the third time. The above three guiding alignments reduce the difficulty of lifting and installation, facilitate operation, and ensure that the blades and the hub can be accurately docked.

[0049] like Figure 1 and Figure 5 As shown, the hoisting mechanism 8 also includes a support column 87 , and the lower end surface of the suspension plate 7 is fixedly provided with a support column 87 whose axis is colinear with the axis of the fixing column 2 , and the upper end surface of the fixing column 2 is provided with a placement groove for accommodating the support column 87 .

[0050] like Figure 1 , Figure 5 and Figure 6As shown, the fixing unit 4 includes a rectangular groove 40, and the upper end surface of the supporting plate 3 is provided with a plurality of rectangular grooves 40 evenly distributed in the circumferential direction. A clamping plate 41 penetrating the rectangular groove 40 is provided at the bottom of the accommodating groove for radial sliding therein, and the clamping plate 41 is arc-shaped, and a spring rod 42 with a horizontal axis is fixedly provided between the outer arc surface of the clamping plate 41 and the inner wall of the accommodating groove.

[0051] like Figure 1 , Figure 5 and Figure 6 As shown, the fixing unit 4 also includes a triangular block 43, and the inner arc surface of the clamping plate 41 is fixedly provided with the triangular block 43, and the inclined surface of the triangular block 43 gradually tilts upward along the direction from the fixing column 2 to the clamping plate 41, and the lower end surface of the supporting plate 3 is fixedly provided with an L-shaped driving block 44 corresponding to the triangular block 43, and the horizontal section of the driving block 44 is matched with the inclined surface of the corresponding triangular block 43.

[0052] During operation, first, the external lifting equipment lifts the wheel hub and places it on the supporting plate 3, and makes the three clamping plates 41 located in the wheel hub. The supporting plate 3 moves down due to the gravity of the wheel hub itself, and the supporting plate 3 drives the driving block 44 thereon to move down synchronously. The cooperation between the driving block 44 and the triangular block 43 makes the triangular block 43 drive the corresponding clamping plate 41 to move, and the three clamping plates 41 move away from each other, and finally the clamping plate 41 is tightly attached to the inside of the bottom installation part of the wheel hub (which is used to connect with the top equipment in the wind power generation equipment). At this time, the supporting plate 3 stops moving downward, and the three clamping plates 41 press against the wheel hub to limit the position of the wheel hub, thereby improving the stability in the subsequent alignment installation process. In the above process, the spring rod 42 is compressed. After the subsequent installation is completed, the external lifting equipment lifts the wheel hub and the blades. At this time, the supporting plate 3 loses the gravity of the wheel hub, and the elastic force generated by the deformation of the spring rod 42 resets the supporting plate 3 and the clamping plate 41.

[0053] After completing the placement of the hub, the suspension plate 7 is placed by an external lifting device. The detachable installation of the suspension plate 7 prevents the subsequent suspension plate 7 from affecting the removal of the hub and the blades. Secondly, during the placement of the suspension plate 7, the support column 87 is inserted into the placement groove to support the suspension plate 7, thereby improving the stability during the subsequent guiding alignment process.

[0054] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0055] In addition, the terms "first", "second", "number one", "number two" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.
