Description

Technical Field

[0002] The wind turbine tower is the tower pole for wind power generation. It mainly plays a supporting role in the wind turbine generator set and absorbs the vibration of the unit. The wind turbine tower is assembled from multiple stages. When installing the wind turbine tower pole, the wind turbine tower is assembled step by step by hoisting.

[0003] Due to the high requirements for assembly accuracy of wind turbine towers, a positioning device is required to assist in the installation of wind turbine towers. Since the diameter of the wind turbine tower gradually decreases from bottom to top, when the positioning device is used for auxiliary installation, a guide sleeve or guide groove is usually set at the tower connection position. A guide sleeve is provided at the end of one tower section, and a guide shaft or a structure that can slide in the guide groove is provided at the corresponding end of the other tower section. During installation, the tower sections can be accurately docked through the guidance of the guide structure.

[0004] When the above-mentioned method is used for guided docking, since the entire wind power tower is composed of multiple tower sections, the docking method of using a guide sleeve in conjunction with a guide groove requires the installation of the guide sleeve and the guide groove each time the docking is performed, and the removal is required after the docking is completed, resulting in the cumbersome process of the entire docking step, affecting the installation efficiency of the tower; since it is installed at high altitude, too much docking equipment will increase the burden on the staff during their work and affect their work efficiency.

In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0032] like Figure 1As shown, a positioning device for connecting a wind turbine tower comprises a fixing plate 1, on which an adjusting mechanism 2 is arranged, three bidirectional telescopic connecting rods 6 are evenly distributed on the vertical surface of the fixing plate 1, the bidirectional telescopic connecting rod 6 is composed of a fixed section and two telescopic sections, the fixed section of the bidirectional telescopic connecting rod 6 is provided with a first limiting bolt which is relatively fixed with the telescopic sections, a positioning mechanism 4 supported on the inner wall of the wind turbine tower is commonly arranged on one end of the three bidirectional telescopic connecting rods 6 away from the fixing plate 1, three evenly distributed auxiliary mechanisms 5 for assisting the connection of two sections of the wind turbine tower are arranged on the top of the adjusting mechanism 2, and a supporting mechanism 3 is commonly arranged on the positioning mechanism 4 and the fixing plate 1.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, the positioning mechanism 4 includes an auxiliary part 42 hinged on one end of the two-way telescopic connecting rod 6 away from the fixed plate 1, and a V-shaped frame 41 is fixedly connected to the auxiliary part 42. The two cross-sections of the V-shaped frame 41 are set to be large and small. The large cross-sectional area end of two adjacent V-shaped frames 41 is slidably connected to a small cross-sectional area section, and a scale line is set on the small cross-sectional area section of the V-shaped frame 41. The three V-shaped frames 41 together form an equilateral triangle. The three V-shaped frames 41 are slidably connected to each other, and the V-shaped frames 41 are threadedly connected with a sixth limiting bolt 43 that keeps the two adjacent V-shaped frames 41 fixed.

[0034] During specific use, the positioning mechanism 4 is first placed into the interior of the installed wind turbine tower. At this time, the equilateral triangle formed by the three V-shaped frames 41 is scaled proportionally according to the inner diameter of the wind turbine tower and the scale on the small cross-sectional area of ​​the V-shaped frame 41, forming an equilateral triangle with the inner wall of the tower as the reference inscribed circle.

[0035] like Figure 2 , Figure 3 and Figure 4 As shown, the auxiliary component 42 includes two symmetrical mounting seats 422 fixedly connected at the top positions of the V-shaped frame 41, and a connecting roller 421 is rotatably connected between the opposite surfaces of the two mounting seats 422. A limiting plate 423 is fixedly connected to the upper surface of the upper mounting seat 422, and a mounting platform 425 is fixedly connected to the surface of the two mounting seats 422 away from the connecting roller 421. A seventh limiting bolt 426 is threadedly connected to the vertical section of the mounting platform 425, and an end of the seventh limiting bolt 426 close to the connecting roller 421 passes through the V-shaped frame 41 to a position close to the circumferential surface of the connecting roller 421. The seventh limiting bolt 426 is rotatably connected to the corresponding V-shaped frame 41, and the end of the bidirectional telescopic connecting rod 6 away from the fixed plate 1 is hinged to the corresponding mounting platform 425.

[0036] like Figure 1 and Figure 5As shown, the support mechanism 3 includes a sliding sleeve 31 slidably connected to a section of the V-shaped frame 41 with a large cross-sectional area, the sliding sleeve 31 is provided with a second limiting bolt that is relatively fixed with the V-shaped frame 41, the sliding sleeve 31 is rotatably connected with an auxiliary connecting rod 32, an end of the auxiliary connecting rod 32 away from the sliding sleeve 31 is slidably connected with an inverted L-shaped telescopic rod 33, the vertical section of the inverted L-shaped telescopic rod 33 is slidably connected to the auxiliary connecting rod 32, a pin 34 is fixedly connected to the upper surface of the horizontal section of the inverted L-shaped telescopic rod 33, the auxiliary connecting rod 32 is provided with a third limiting bolt that is relatively fixed with the sliding sleeve 31, the auxiliary connecting rod 32 is provided with a fourth limiting bolt that is relatively fixed with the inverted L-shaped telescopic rod 33, the upper surface of the fixed plate 1 is fixedly connected with a fixing platform 35, and a clamping seat 36 is fixedly connected to the upper surface of the fixing platform 35 at a position corresponding to the sliding sleeve 31.

[0037] During specific use, the three V-shaped frames 41 are adjusted to be an equilateral triangle with the inner wall of the tower as the reference circumscribed circle, and the circumferential surfaces of the connecting rollers 421 on the three V-shaped frames 41 are all in contact with the inner wall of the tower. Then, the position of the sliding sleeve 31 on the V-shaped frame 41 is adjusted so that the sliding sleeve 31 is centered on the V-shaped frame 41. After that, the sliding sleeve 31 is limited on the V-shaped frame 41 by the second limiting bolt. Then, the auxiliary connecting rod 32 is rotated to a vertical state on the V-shaped frame 41, and the inverted L-shaped telescopic rod 33 is pulled out from the inside of the auxiliary connecting rod 32 so that the horizontal section of the inverted L-shaped telescopic rod 33 is hung on the upper edge of the installed wind power tower. The auxiliary external horizontal measuring equipment is used to adjust the multiple V-shaped frames 41 to a horizontal state inside the installed wind power tower. At this time, the inverted L-shaped telescopic rod 33 is pulled out from the inside of the auxiliary connecting rod 32. The retractable rod 33 is limited on the auxiliary connecting rod 32, and the auxiliary connecting rod 32 is limited on the sliding sleeve 31 by the fourth limiting bolt, and then the seventh limiting bolt 426 is screwed on the mounting platform 425, so that the end of the seventh limiting bolt 426 close to the connecting roller 421 is pressed against the connecting roller 421, so that the connecting roller 421 and the mounting seat 422 are kept fixed, and the V-shaped frame 41 is kept stable inside the installed wind power tower, and then the three V-shaped frames 41 are fixed by the auxiliary part 42, and at the same time, the two telescopic ends and the fixed end of the two-way telescopic connecting rod 6 are limited by the first limiting bolt, and the mounting platform 425 and the fixed plate 1 are hard-connected by the two-way telescopic connecting rod 6, and the position of the fixed plate 1 is limited by multiple two-way telescopic connecting rods 6.

[0038] like Figure 1 and Figure 6As shown, the adjustment mechanism 2 includes a plurality of groups of evenly distributed connecting strips 22 that slide up and down and penetrate and are connected to the upper surface of the fixed plate 1. The top ends of the plurality of connecting strips 22 are commonly fixedly connected to the connecting plate 21. The center of the lower surface of the connecting plate 21 is rotatably connected to a screw rod 23. The bottom end of the screw rod 23 penetrates through the lower surface of the fixed plate 1 and is fixedly connected to a handle 24. The screw rod 23 is threadedly connected to the fixed plate 1. The bayonet 34 is snap-fitted with its corresponding socket 36. The fixed platform 35 is rotatably connected to the screw rod 23. The positions of the plurality of groups of connecting strips 22 correspond one-to-one to the positions of the plurality of inverted L-shaped telescopic rods 33. The number of each group of connecting strips 22 is two. The inverted L-shaped telescopic rod 33 is located between the opposite surfaces of a corresponding group of two connecting strips 22 and is slidably connected to the connecting strips 22.

[0039] During specific use, when the V-shaped frame 41 remains stable in a horizontal state inside the installed wind turbine tower, the staff rotates the screw rod 23 on the fixed platform 35 by holding the handle 24, and the screw rod 23 pushes the connecting plate 21 to move upward, and the connecting strip 22 drives the auxiliary mechanism 5 to move upward synchronously through the connecting plate 21. When the auxiliary mechanism 5 is adjusted to a suitable position, the limiting of the third and fourth limit bolts is canceled at this time, and the inverted L-shaped telescopic rod 33 is retracted on the auxiliary connecting rod 32 and limited again by the fourth limit bolt. At the same time, after the auxiliary connecting rod 32 is adjusted to a horizontal state, it is limited again by the third limit bolt, and the pin 34 is clamped in the corresponding holder 36 to strengthen the support of the equilateral triangle composed of multiple V-shaped frames 41.

[0040] like Figure 1 and Figure 7 As shown, the auxiliary mechanism 5 includes a mounting frame 51 hinged on the connecting plate 21, an auxiliary alignment plate 54 is hinged on the inner side of the mounting frame 51, and two auxiliary support rods 53 are hinged on the bottom end of the mounting frame 51 and are symmetrically arranged with the auxiliary alignment plate 54 as a reference. Positions on the mounting frame 51 corresponding to the auxiliary support rods 53 are slidably connected with connecting sleeves 52, and one end of the auxiliary support rod 53 away from the auxiliary alignment plate 54 is hinged to the connecting sleeve 52, and a fifth limiting bolt is provided on the connecting sleeve 52 to keep it relatively fixed with the mounting frame 51, and a mounting groove is opened on the auxiliary alignment plate 54, and two auxiliary rollers arranged parallel to the auxiliary alignment plate 54 are rotatably connected inside the mounting groove.

[0041] When in use, when adjusting the position of the auxiliary mechanism 5, the connecting plate 21 is raised to an appropriate height. At this time, the staff pushes the installation frame 51 to rotate on the connecting plate 21, and after the bottom ends of the three installation frames 51 are all pushed to the top of their corresponding installation seats 422, the staff cooperates with the staff to reversely rotate the screw rod 23 to drive the installation frame 51 to move downward. At this time, the bottom end of the installation frame 51 slides on the installation seat 422 until it contacts the limit plate 423 and then stops rotating the screw rod 23. Then the staff adjusts the inclination angle between the auxiliary alignment plate 54 and the installation frame 51 according to the inner diameter of the wind turbine tower to be installed. When the auxiliary alignment plate 54 rotates, the connecting sleeve 52 is driven to slide on the installation frame 51 through the auxiliary support rod 53. When the inclination angle of the auxiliary alignment plate 54 is adjusted, the connecting sleeve 52 is limited to the installation frame 51 through the fifth limit bolt, and the bottom end of the auxiliary alignment plate 54 is supported in cooperation with the auxiliary support rod 53.

[0042] Then, the upper wind turbine tower is hoisted to the top of the connecting plate 21 by external hoisting equipment and then moved downward. The auxiliary rollers on the three inclined auxiliary alignment plates 54 make the upper wind turbine tower slide downward in close contact with the auxiliary alignment plates 54 until it docks with the installed wind turbine tower. At this time, the preliminary docking is completed. Then the staff cancels the limit of the fifth limit bolt and restores the auxiliary alignment plate 54 to its original position on the installation frame 51. At the same time, the installation frame 51 is pushed upward by rotating the screw rod 23. After the bottom end of the installation frame 51 is separated from the mounting seat 422, the screw rod 23 is rotated in the opposite direction to move the installation frame 51 downward. The connecting roller 421 is restored to its original position, and then the limiting of the seventh limiting bolt 426 on the connecting roller 421 is canceled, and the limiting of the sixth limiting bolt 43 is canceled. The connecting roller 421 is moved to the joint between the two wind turbine towers by moving the V-shaped frame 41, and then the positioning steps of the connecting roller 421 are repeated to make the connecting roller 421 close to the joint position of the two wind turbine towers. Then, the staff generates thrust on the V-shaped frame 41 to drive the connecting roller 421 to roll along the joint of the two wind turbine towers, and perform secondary docking between the two wind turbine towers, so that the two wind turbine towers are aligned (such as Figure 8 As shown), the connecting roller 421 is then moved away from the joint position (it should be noted that, since the external lifting equipment keeps the upper-level wind turbine tower in a lifting state, the staff can easily move the position of the upper-level wind turbine tower so that the two wind turbine towers are coaxially aligned), and then the staff tightens the connection between the two wind turbine towers. The above steps can be repeated to connect multiple levels of wind turbine towers.

[0043] Working principle: When in use, first place the V-shaped frame 41 inside the installed wind turbine tower, then rotate the auxiliary connecting rod 32 to vertical, pull the inverted L-shaped telescopic rod 33 out of the auxiliary connecting rod 32, so that the horizontal section of the inverted L-shaped telescopic rod 33 is hung on the upper edge of the wind turbine tower, and then adjust the relative positions of the three V-shaped frames 41 according to the inner diameter of the wind turbine tower, and synchronously adjust the position of the sliding sleeve 31 so that the sliding sleeve 31 is in a centered position on the V-shaped frame 41, so that the auxiliary component 42 fits against the inner wall of the wind turbine tower. After the auxiliary horizontal measuring device adjusts the V-shaped frame 41 to be horizontal, tighten the third and fourth bolts on the auxiliary connecting rod 32 to keep the auxiliary component 42 stationary, and then adjust the position of the mounting frame 51 by rotating the screw 23. After the bottom end of the mounting frame 51 is against the auxiliary component 42, according to the inner diameter of the wind turbine tower to be installed. Adjust the position of the connecting sleeve 52 on the installation frame 51 so that the multiple auxiliary alignment plates 54 are tilted, and then the wind turbine tower to be installed is hoisted to the top of the auxiliary alignment plates 54 through external hoisting equipment, so that the wind turbine tower to be installed is sleeved on the multiple auxiliary alignment plates 54, and the auxiliary alignment plates 54 are used to perform preliminary docking with the installed wind turbine tower. After the preliminary docking is completed, the multiple V-shaped frames 41 are contracted, and the above steps are repeated to readjust the position of the V-shaped frame 41 at the joint of the two wind turbine towers, and then the joint of the two wind turbine towers is rolled by rotating the V-shaped frame 41 and cooperating with the auxiliary parts 42, and the two wind turbine towers are docked for the second time to align the two wind turbine towers, and then the staff firmly connects the two wind turbine towers, contracts the multiple V-shaped frames 41 again, and repeats the above steps to install the next level of wind turbine tower.
