Description

Technical Field

[0001] The present application relates to the technical field of wind power generation hoisting construction, and in particular to a guide device. Background Art

[0002] As wind turbine manufacturers have successively launched large-diameter segmented wind towers, new requirements have been put forward for the assembly and hoisting of segmented towers. In order to ensure the ovality of the flange during the assembly of the segmented tower and solve the problem of the alignment of the upper and lower flange bolt holes during hoisting.

[0003] In existing technology, the guiding device mainly uses guide rods, which are manually inserted into the bolt connection holes of the upper and lower flanges to guide the tower hoisting. However, this solution easily wears the anti-corrosion protective coating on the guide rods, and the manual insertion is inconvenient, thus reducing the efficiency of tower hoisting.

[0004] In summary, how to ensure the concentricity of the upper and lower tower barrels when hoisting a segmented tower and improve the hoisting efficiency of the tower is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of the present application is to provide a guiding device, which can ensure the concentricity of the upper and lower towers when the segmented tower is hoisted, and at the same time can improve the hoisting efficiency of the tower.

[0006] To achieve the above-mentioned purpose, the present application provides a guiding device for a segmented tower, wherein the tower includes multiple first tower segments and multiple second tower segments, and the guiding device includes: a first guide member, which is arranged between two adjacent first tower segments, so that all the first tower segments are assembled into a first tower; a second guide member, which is arranged between two adjacent second tower segments, so that all the second tower segments are assembled into a second tower. When the first tower and the second tower are docked up and down, the first guide member and the second guide member are plugged into each other to align the first tower and the second tower.

[0007] Preferably, the first guide member comprises:

[0008] a connecting portion provided on the inner side walls of two adjacent first tower segments, for connecting the two first tower segments, with the bottom end of the connecting portion being flush with the bottom end of the first tower segment;

[0009] The protrusion has one end connected to the connecting portion and the other end extending to the outside of the first tower along the axial direction of the first tower, and is used to be inserted into the second guide member.

[0010] Preferably, the second guide member comprises:

[0011] A guide body is provided on the inner sidewalls of two adjacent second tower segments and is used to connect the two second tower segments, with the top end of the guide body being flush with the top end of the second tower segment;

[0012] A groove is provided through the guide body on a side of the inner side wall facing away from the second tower segment, and is used for the protrusion to be inserted.

[0013] Preferably, the connecting portion and the guide body are respectively connected to the first tower segment and the second tower segment by bolts.

[0014] Preferably, the side of the groove facing the inner side wall of the second tower segment has a first slope for avoiding the bolt, and the side of the protrusion facing the inner side wall of the first tower segment has a second slope adapted to the groove.

[0015] Preferably, the connecting portion is rectangular, and a side facing the inner side wall of the first tower is arc-shaped, so as to fit tightly with the inner side wall of the first tower.

[0016] Preferably, the guide body is rectangular, and the side facing the inner side wall of the second tower is arc-shaped, so as to fit tightly with the inner side wall of the second tower.

[0017] Preferably, the protrusion and the groove are trapezoidal in shape, and the shapes and sizes of the two are matched.

[0018] Compared with the above background technology, the present application adds a first guide and a second guide. Two adjacent first tower segments are connected by the first guide so that all the first tower segments are assembled into a first tower. Two adjacent second tower segments are connected by the second guide so that all the second tower segments are assembled into a second tower. When the first tower is hoisted to the top of the second tower, the first guide is aligned with the second guide and inserted until the end face of the first tower fits tightly with the end face of the second tower, thus completing the positioning of the first tower and the second tower. In this way, the device not only ensures the ellipticity of the tower when the segmented tower is assembled, but also ensures the concentricity of the upper and lower towers when the tower is hoisted, and improves the hoisting efficiency.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0028] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0029] The present application provides a guide device for a segmented tower, the tower comprising a plurality of first tower segments 11 and a plurality of second tower segments 21, and the guide device comprising a first guide member 30 and a second guide member 40. The first guide member 30 is disposed between two adjacent first tower segments 11 to allow all first tower segments 11 to be assembled into a first tower 10; the second guide member 40 is disposed between two adjacent second tower segments 21 to allow all second tower segments 21 to be assembled into a second tower 20. When the first tower 10 and the second tower 20 are vertically butted together, the first guide member 30 and the second guide member 40 are plugged into each other to align the first tower 10 and the second tower 20.

[0030] Specifically, a first guide member 30 is taken, one end of which is mounted on the side of any first tower segment 11, and the other end is mounted on the side of another first tower segment 11, thereby joining the two first tower segments 11. Then, another first guide member 30 is taken, and the other sides of the two first tower segments 11 are joined to the sides of any other two first tower segments 11 according to the above steps. Similarly, all the first tower segments 11 are assembled into the first tower 10, so that the first tower 10 has a cylindrical shape. Correspondingly, the second tower 20 is also assembled according to the above steps.

[0031] Further, with the Figure 1 For reference, a plurality of first guide members 30 are evenly provided on the inner wall of the assembled first tower 10, and a plurality of second guide members 40 are evenly provided on the inner wall of the assembled second tower 20, and the first guide members 30 are arranged one-to-one corresponding to the second guide members 40.

[0032] After the first tower 10 and the second tower 20 are assembled, the second tower 20 is hoisted first. After the second tower 20 is firmly fixed, the first tower 10 is hoisted. When the first tower 10 is hoisted to the top of the second tower 20, the first guide 30 is aligned with the second guide 40 and inserted until the end face of the first tower 10 fits tightly with the end face of the second tower 20, so that the centers of the mounting holes of the bolts 50 on the first tower 10 and the second tower 20 are aligned. Finally, the first tower 10 and the second tower 20 are tightened and fixed by the bolts 50. In this way, the device not only ensures the ellipticity of the tower when the segmented tower is assembled, but also ensures the concentricity of the upper and lower towers when the tower is hoisted.

[0033] In addition, the above-mentioned guide device also solves the problems of difficult installation, low installation efficiency and high construction safety risks when aligning the tower.

[0034] Based on the above embodiment, as a further preferred embodiment, the first guide member 30 includes a connecting portion 31 and a raised portion 32. The connecting portion 31 is provided on the inner sidewalls of two adjacent first tower segments 11 for connecting the two first tower segments 11, and the bottom end of the connecting portion 31 is flush with the bottom end of the first tower segment 11. The raised portion 32 has one end connected to the connecting portion 31 and the other end extending axially along the first tower segment 10 to the outside of the first tower segment 10 for insertion into the second guide member 40.

[0035] Specifically, the connecting portion 31 is arranged on the inner side wall of the lower flange seat 111 of the two adjacent first tower segments 11, and the bottom end of the connecting portion 31 is flush with the bottom end of the lower flange seat 111, wherein the connecting portion 31 and the raised portion 32 can be arranged in one piece, and the whole is rectangular, wherein the shape of the raised portion 32 is adapted to the shape of the groove 42.

[0036] Based on the above embodiment, as a further preferred embodiment, the second guide member 40 includes a guide body 41 and a groove 42. The guide body 41 is provided on the inner sidewalls of two adjacent second tower segments 21 for connecting the two second tower segments 21, and the top of the guide body 41 is flush with the top of the second tower segment 21; the groove 42 is provided through the side of the guide body 41 facing away from the inner sidewall of the second tower segment 21 for receiving the protrusion 32.

[0037] Attach Figure 1 With the orientation as a reference, the guide body 41 is arranged on the inner wall of the upper flange seat 211 of the two adjacent second tower segments 21, and the bottom end of the guide body 41 is flush with the bottom end of the upper flange seat 211. In order to install the bolt 50, the groove 42 is arranged through the outer edge of the guide body 41. Of course, the relative position relationship between the guide body 41 and the groove 42 is not limited in this application.

[0038] On the basis of the above embodiment, as a further preference, the connecting portion 31 and the guide body 41 are respectively connected to the first tower segment 11 and the second tower segment 21 by bolts 50 .

[0039] Specifically, four bolt 50 mounting holes are provided at intervals on the guide body 41 for screws to pass through so as to fix the guide body 41 between two adjacent second tower segments 21, wherein two bolt 50 mounting holes are installed on any second tower segment 21 by bolts 50, and then the other two bolt 50 mounting holes are installed on the adjacent second tower segment 21 by bolts 50. In this way, while the guide body 41 is fixed, the two adjacent second tower segments 21 are also connected together.

[0040] Correspondingly, four bolt 50 mounting holes are also provided at intervals on the connecting portion 31 for screws to pass through so as to fix the connecting portion 31 between two adjacent first tower segments 11, wherein two bolt 50 mounting holes are installed on any first tower segment 11 by bolts 50, and then the other two bolt 50 mounting holes are installed on the adjacent first tower segment 11 by bolts 50. In this way, while the connecting portion 31 is fixed, the two adjacent first tower segments 11 are also connected together.

[0041] In addition, the connecting portion 31 and the guide body 41 can be precisely installed on the first tower segment 11 and the second tower segment 21 by means of the positioning pins 60 , and then tightened and fixed by means of the bolts 50 .

[0042] On the basis of the above embodiment, as a further preference, the side of the groove 42 facing the inner wall of the second tower segment 21 has a first slope for avoiding the bolt 50, and the side of the protrusion 32 facing the inner wall of the first tower segment 11 has a second slope adapted to the groove 42.

[0043] Specifically, with Figure 1 Taking the orientation of the first ramp as a reference, the upper end of the first ramp is positioned closer to the inner sidewall of the second tower segment 21 than the lower end. In other words, the width of the groove 42 gradually decreases from the upper end to the lower end. Accordingly, the upper end of the second ramp is positioned closer to the inner sidewall of the first tower segment 11 than the lower end. This prevents the protrusion 32 from being inserted into the groove 42 without causing a connection failure due to the bolt 50.

[0044] On the basis of the above embodiment, as a further preference, the connecting portion 31 is rectangular, and the side facing the inner wall of the first tower 10 is arc-shaped, so as to fit tightly with the inner wall of the first tower 10 .

[0045] Specifically, the surface where the connecting portion 31 fits with the first tower segment 11 is set to be arc-shaped and is concentric with the first tower segment 11. That is to say, the outer diameter of the connecting portion 31 is equal to the inner diameter of the first tower segment 11. In this way, by tightly fitting the connecting portion 31 with the inner walls of the two adjacent first tower segments 11 at the same time, the ellipticity of the spliced ​​first tower 10 can be ensured.

[0046] On the basis of the above embodiment, as a further preference, the guide body 41 is rectangular, and the side facing the inner wall of the second tower 20 is arc-shaped, so as to fit tightly with the inner wall of the second tower 20 .

[0047] Similarly, the surface where the guide body 41 fits with the second tower segment 21 is set to be an arc shape, and is set concentrically with the second tower segment 21. In this way, by tightly fitting the guide body 41 with the inner walls of the two adjacent second tower segments 21 at the same time, the ellipticity of the spliced ​​second tower 20 can be ensured.

[0048] On the basis of the above embodiment, as a further preference, the protrusion 32 and the groove 42 are trapezoidal in shape, and the shapes and sizes of the two are adapted to each other.

[0049] Of course, the shapes and sizes of the protrusion 32 and the groove 42 are not limited in this application, and are only set according to actual installation conditions.

[0050] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0051] The above is a detailed introduction to the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only intended to help understand the method and core ideas of the present application. It should be noted that, for those skilled in the art, without departing from the principles of the present application, several improvements and modifications may be made to the present application, and such improvements and modifications also fall within the scope of protection of the claims of the present application.
