Description

Technical Field

[0001] The present application relates to the technical field of wind power generation, and more specifically, to a tower connection auxiliary tooling. Background Art

[0002] Wind turbines use towers to position their rotors high in the air, effectively capturing wind energy. Commonly used towers in existing technology include steel and concrete. Compared to steel, concrete towers offer advantages such as lower cost, longer service life, and greater stability. Therefore, most current wind turbines utilize concrete towers. As wind turbine capacity increases, the diameter and height of concrete towers also increase. This necessitates dividing the tower into multiple segments, which must then be connected vertically during installation.

[0003] In the prior art, slurry is typically used to bond two adjacent tower sections together. Specifically, when installing the tower, the first tower section is pre-installed, and then slurry is applied to the upper surface of the first tower section. The second tower section is then lowered onto the first tower section and the slurry according to the corresponding position. After the slurry solidifies, the upper and lower tower sections are connected together. However, this connection method has the problem of slurry being squeezed out and falling from the inside and outside of the tower, resulting in significant slurry loss. In addition, if too much slurry is squeezed out, the slurry filling at the joint between the two adjacent tower sections will not be full, which will lead to reduced connection quality.

[0037] In order to solve the problems existing in the tower installation process in the prior art, the present application provides a tower installation auxiliary tooling for assisting the connection between two adjacent tower sections. The tower installation auxiliary tooling provided in the embodiment of the present application is annular as a whole and can be arranged around the inner side and / or outer side of the joint between two adjacent tower sections to prevent the slurry at the joint from falling and reduce the loss of slurry. In addition, through the sealing and squeezing effect of the tower installation auxiliary tooling, the slurry at the joint is filled more fully and more tightly, thereby improving the connection quality between the two tower sections.

[0038] According to the tower installation auxiliary tooling of the embodiment of the present application, after two adjacent tower sections are connected together, the tower installation auxiliary tooling can be retained on the tower to enhance the connection quality and strength of the tower. The tower installation auxiliary tooling can also be removed after the two tower sections are connected so that it can be reused when the next group of towers is connected.

[0039] According to the tower installation auxiliary tooling of the embodiment of the present application, it can be a complete annular component or an annular component formed by multiple split arc segments connected to each other, so as to facilitate disassembly and adaptively adjust the circumferential size of the annular component according to the circumference of the tower.

[0040] The tower installation auxiliary tooling according to the embodiment of the present application can be made of a thin sheet made of metal, rubber, or resin, a ring-shaped member made of a hard material with a fixed shape, or a ring-shaped member enclosed by long strips with certain bending properties.

[0041] As an example, the annular member can be formed by a single belt, or by multiple belts connected and enclosed. In the storage and transportation state, the long belt can be unfolded into a flat shape, thereby facilitating stacking and storage, and reducing the space occupied.

[0042] Below, a detailed description will be given with reference to the accompanying drawings, taking as an example how the tower installation auxiliary tooling can be removed from the tower for reuse.

[0043] like Figure 1 As shown, the tower installation auxiliary tooling according to the present application includes a long strip of belt 110, a first connecting portion 120 provided at the first end of the belt 110, and a second connecting portion 130 provided at the second end of the belt 110. Figure 2 As shown, the first connecting portion 120 and the second connecting portion 130 can be connected to each other, so that the tower installation auxiliary tooling can be enclosed into an annular component, thereby being sleeved on the outside and / or inside of the tower at the joint of two adjacent concrete tower sections.

[0044] The tower includes multiple concrete tower sections stacked in sequence in the height direction. For the convenience of description, the two adjacent tower sections are called the first tower section and the second tower section, and the first tower section is located below the second tower section.

[0045] During the connection process of two adjacent tower sections, when the second tower section falls downward on the upper end surface of the first tower section, a joint is formed between the two. The joint has an inner outlet and an outer outlet in the radial direction of the tower. The slurry in the joint may overflow and fall from the outer outlet, or may overflow and fall from the inner outlet. Therefore, the tower installation auxiliary tooling according to the present application can be mounted on the outside of the joint to block the slurry from the outside of the joint, while the excess slurry is squeezed out from the inner outlet of the joint. In addition, the tower installation auxiliary tooling according to the present application can also be mounted on the inside of the joint to block the slurry from the inside of the joint, so that the excess slurry is squeezed out from the outer outlet of the joint.

[0046] Of course, the tower installation auxiliary tooling according to the present application can also be installed on both the inner and outer sides of the joint to seal the joint from both sides at the same time. However, in this case, a certain overflow port needs to be reserved to squeeze out the excess slurry to avoid local imbalance at the joint between the first tower section and the second tower section, which may cause inaccurate docking between the tower sections or tilting of the tower sections. As an example, when the tower installation auxiliary tooling according to the present application is installed on both the inner and outer sides of the joint, some overflow ports can be opened on the belt body 110 to ensure that the excess slurry can be squeezed out from the overflow port.

[0047] To cover and seal the joint between adjacent tower sections, the band 110 has a certain width and length. The width of the band 110 corresponds to the height of the tower and is greater than the width of the joint between the two adjacent tower sections. For example, the width of the band 110 is typically 6-10 cm, but is not limited to this. It is sufficient as long as it can roughly cover the joint and overlap the upper and lower edges of the joint, thereby sealing the joint and preventing slurry from overflowing. The length of the band 110 is substantially equal to or slightly greater than the circumference of the joint between the two adjacent tower sections. This prevents a large gap between the band 110 and the surface of the tower sections when the band is placed at the joint, thereby preventing slurry from squeezing out of the gap between the two sections. As an example, a certain gap between the band 110 and the surface of the first tower section, for example, 4-6 mm, is provided to facilitate the lifting of the second tower section and prevent the band 110 from being squeezed during the lowering of the second tower section.

[0048] According to the tower installation auxiliary tooling of the embodiment of the present application, the belt body 110 is a ring-shaped component formed by enclosing long strips with certain bending properties. In the storage and transportation state, the long strips can be unfolded into a flat shape, thereby facilitating stacking and storage, reducing the occupied space.

[0049] According to an embodiment of the present application, the belt body 110 is a single belt provided as an integral body, the first connecting portion 120 is provided at the first end of the belt body 110, and the second connecting portion 130 is provided at the second end of the belt body 110. Figures 1 to 3 In the example shown, the first connecting portion 120 includes a hook, and the second connecting portion 130 includes a locking ring 132. The locking ring 132 can be connected to the hook, thereby enclosing the belt body 110 into a ring shape and sleeved on one radial side of the seam to prevent the slurry from overflowing and falling therefrom.

[0050] According to some embodiments of the present application, the locking ring 132 can be formed as a buckle that can be flipped left and right or up and down relative to the belt body 110. After the two ends of the belt body 110 are docked in place, the locking ring 132 can be flipped so that the locking ring 132 is hung on the hook, thereby circumferentially restraining the first connecting portion 120 and the second connecting portion 130, preventing the two ends of the belt body 110 from disengaging from each other. To further prevent the locking ring 132 from disengaging from the hook, a latch can be provided. In this case, the hook is provided with a pin hole. After the latch is inserted into the pin hole, the locking ring 132 can be restrained on the hook.

[0051] According to other embodiments of the present application, the lock ring 132 is provided with a ring hole, and the hook is connected to the lock ring 132 by being inserted into the ring hole. The second connecting portion 130 also includes a lock ring driving portion, and by operating the lock ring driving portion, the lock ring 132 can be moved relative to the hook, thereby locking or releasing the hook.

[0052] like Figure 4 As shown, as an example, the locking ring drive unit includes a handle 134 and a linkage bracket 131. Specifically, the first end of the handle 134 is rotatably connected to the end of the belt body 110 via a first pivot axis 133. The first end of the linkage bracket 131 is rotatably connected to the handle 134 via a second pivot axis 135. The second pivot axis 135 is located between the first and second ends of the handle 134. The locking ring 132 is disposed at the second end of the linkage bracket 131. When the second end of the handle 134 is operated to rotate about the first pivot axis 133, the linkage bracket 131 is driven to move, thereby locking or releasing the locking ring 132 from the hook.

[0053] As an example, when the handle 134 is in a horizontal direction, or when the length direction of the handle 134 is consistent with the circumferential direction of the belt body 110, the locking ring 132 can be locked with the hook of the first connecting part 120. When the handle 134 is rotated from the locked position to the vertical direction, the locking ring 132 can be driven to move and thereby release from the hook.

[0054] The rotation direction of the handle 134 depends on the direction in which the locking ring 132 is connected to the hook. Figure 3 and attached Figure 4 In the illustrated example, the hook extends in a direction substantially parallel to the surface of the belt body 110. Therefore, the locking ring 132 can be engaged with the hook from a height direction, thereby rotating the handle 134 within a vertical plane. However, the hook can also extend along the thickness direction of the belt body, that is, in the radial direction of the annular member. In this case, the locking ring 132 is engaged with the hook in a horizontal direction, and the handle 134 is rotated within the horizontal plane.

[0055] According to one aspect of an embodiment of the present application, the locking ring 132 may be fixedly connected to the linkage bracket 131 .

[0056] According to another aspect of the embodiment of the present application, the locking ring 132 can be movably connected to the linkage bracket 131, and an elastic member 137 is further provided between the locking ring 132 and the linkage bracket 131. The provision of the elastic member 137 can ensure the locking force between the locking ring 132 and the hook, and ensure the locking state between the two, so that they will not be easily disengaged.

[0057] As an example, the linkage bracket 131 is formed as a frame structure, a ring hole is formed at the first end of the locking ring 132, and the second end of the locking ring 132 is inserted into the frame structure of the linkage bracket 131. The elastic member 137 is disposed in the frame structure and applies a force to the locking ring 132 toward the handle 134. As an example, the elastic member 137 is a compression spring, and a spring support flange is formed at the second end of the locking ring 132. One end of the spring abuts against the support flange of the locking ring 132, and the second end of the spring abuts against the inner surface of the linkage frame.

[0058] Due to the presence of elastic member 137, locking ring 132 can move relative to linkage bracket 131, thereby controlling the extension of locking ring 132 relative to linkage bracket 131, and further controlling the extension position of locking ring 132. This allows for a certain adjustment margin in the circumference of the tower installation auxiliary tooling after it is formed into a ring shape. In addition, due to the elastic force of elastic member 137, locking ring 132 tends to be pulled toward linkage bracket 131. Therefore, when locking ring 132 is engaged with the hook, the elastic force of elastic member 137 can ensure that locking ring 132 is always locked to the hook.

[0059] Furthermore, the provision of elastic member 137 can also prevent handle 134 from rotating arbitrarily in the locked state, thereby preventing the unlocked state from being released, thereby improving locking reliability. Specifically, because linkage bracket 131 is connected to the handle via second pivot axis 135, in the locked state, linkage bracket 131 applies a pulling force to handle 134 at second pivot axis 135. Under the action of this pulling force, a torque is generated that causes handle 134 to rotate about first pivot axis 133, resulting in handle 134 having a tendency to rotate about first pivot axis 133.

[0060] During the operation of locking the locking ring 132 with the hook by rotating the handle 134, the handle 134 is rotated in a first direction, for example, Figure 4In the embodiment, the first direction is counterclockwise. Before the second pivot axis 135 is aligned with the first pivot axis 133 and the locking ring 132, the locking ring 132, under the action of the elastic force, exerts a torque on the handle 134 in the opposite direction of the first direction. In this case, the locking ring 132 and the hook cannot be locked. When the second pivot axis 135, the first pivot axis 133, and the locking ring 132 are aligned, the locking ring 132 and the hook are locked. At this point, the locking force between the locking ring 132 and the hook and the elastic force of the elastic member are aligned. However, this state is not stable. If the handle 134 is subjected to vibration or a small external force, it can easily move relative to its position, resulting in unlocking.

[0061] When the handle 134 continues to rotate in the first direction, the second pivot axis 135 will deviate from the straight line where the first pivot axis 133 and the locking ring 132 are located. Under the action of elastic force, the locking ring 132 applies a torque in the same direction as the first direction to the handle 134, thereby preventing the handle 134 from rotating in the opposite direction, so that the locking ring 132 and the hook are in a stable locking state, ensuring reliability during use.

[0062] After the handle 134 rotates along the first direction and crosses the straight line where the first pivot axis 133 and the locking ring 132 are located and continues to rotate by a predetermined angle, the handle 134 can abut against the belt body 110 or a pad or protrusion provided on the belt body 110 to prevent the handle 134 from continuing to rotate.

[0063] By reversing the handle 134, the lock can be released, thereby facilitating the disassembly of the tower installation auxiliary tooling according to the present application. Since quick connection and removal can be achieved by simply rotating the handle 134, the auxiliary connection and removal process is reduced, and the timeliness of tower installation work is improved.

[0064] According to an embodiment of the present application, in order to enable the locking ring 132 to move stably relative to the linkage bracket 131, a guide groove 136 is opened on the side wall of the linkage bracket 131, and the spring support flange 139 on the locking ring 132 can be inserted into the guide groove 136 and move stably under the constraint of the guide groove 136.

[0065] To improve connection stability and firmness, a first reinforcing pad 128 is provided at the first end of the belt body 110, the first connecting portion 120 is disposed on the first reinforcing pad 128, and a second reinforcing pad 138 is provided at the second end of the belt body 110, the second connecting portion 130 is disposed on the second reinforcing pad 138. As an example, the belt body 110 may be a stainless steel belt, and the first reinforcing pad 128 and the second reinforcing pad 138 may be angle steels, which may be welded to the belt body 110 to increase the thickness and strength of the connection and prevent fracture at the connection between the belt body 110 and the first connecting portion 120 and the second connecting portion 130.

[0066] Typically, the tower is relatively large, and the length of a single belt is insufficient to enclose and form a complete hoop. Therefore, according to an embodiment of the present application, the belt 110 is divided into a plurality of belt segments in the length direction, such as Figure 1 As shown, the belt body 110 includes three belt sections, namely a first section 100, a tail section 200 and a middle section 300. The belt body 110 can be at least two sections, that is, at least including the first section 100 and the tail section 200, and can also include at least one middle section 300 located between the first section 100 and the tail section 200.

[0067] The first connecting portion 120 and the second connecting portion 130 are respectively disposed at the butted ends of the first segment 100 and the tail segment 200. In addition to the connected end of the first segment 100 and the tail segment 200, the other two adjacent segments are respectively provided with a third connecting portion 140 and a fourth connecting portion 150, which can be connected to each other.

[0068] like Figure 5 、 Figure 6 and Figure 7 As shown, the third connecting portion 140 and the fourth connecting portion 150 are each an L-shaped or T-shaped pad, one end of which is fixedly connected to the belt body 110, and the other end of which is formed with a through hole. For example, the third connecting portion is provided with a through hole 141, and the fourth connecting portion 150 is provided with a through hole 151. The third connecting portion 140 and the fourth connecting portion 150 can be connected to each other by passing a bolt 171 through the through holes and engaging a nut 172.

[0069] At the location where the third connecting portion 140 and the fourth connecting portion 150 are connected to each other, the ends of the belt body 110 may overlap with each other, thereby improving the sealing performance of the joints of the tower sections.

[0070] Furthermore, the circumference of the entire clamp can be adaptively adjusted by adjusting the length of the bolts 171. For example, when the entire length of the belt body 110 is smaller than the circumference of the tower, a longer bolt 171 can be used to appropriately adjust the distance between the third connecting portion 140 and the fourth connecting portion 150 to increase the circumference of the clamp to match the circumference of the tower.

[0071] By providing a backing plate and positioning the first and second connecting portions 120 and 130 on the protruding portion of the backing plate, the handle 134 can be separated from the belt body 110 by a certain distance, facilitating rotation and preventing interference. Furthermore, the backing plate protrudes laterally from the belt body 110, allowing the handle 134 to rotate in a vertical direction parallel to the plane of the belt body, providing ample rotational space and facilitating locking and unlocking operations.

[0072] Hereinafter, the surface of the belt body 110 facing away from the tower section is referred to as the first surface, and the surface facing the tower section is referred to as the second surface. The first connecting portion 120 , the second connecting portion 130 , the third connecting portion 140 and the fourth connecting portion 150 are all arranged on the first surface of the belt body 110 .

[0073] like Figure 8 As shown, an insertion protrusion 180 is provided on the second surface of the belt body 110. The insertion protrusion 180 may be a stainless steel sheet or a bolt welded to the belt body 110. When the tower installation auxiliary tool is installed at the joint of the tower sections, the insertion protrusion 180 can be inserted into the joint between two adjacent concrete tower sections to prevent the tower installation auxiliary tool from sliding down along the tower sections.

[0074] As an example, the length of the insertion protrusion 180 is 1 cm to 2 cm, so as to prevent the insertion protrusion 180 from being too long and being difficult to be pulled out of the slurry, and effectively prevent the reduction of the connection quality at the joint.

[0075] The insertion protrusion 180 is arranged in the middle part of the width direction of the belt body 110. When the belt body 110 is set to the tower section, the insertion protrusion 180 is located on the upper surface of the tower section. The lower part of the width direction of the belt body 110 is wrapped around the outer periphery of the first tower section, and the upper part of the width direction of the belt body 110 protrudes a predetermined height relative to the upper surface of the first tower section, so that it can surround the outer periphery of the lower end part of the second tower section.

[0076] According to an embodiment of the present application, a plurality of insertion protrusions 180 are provided, spaced apart along the length of the belt body 110. Compared to a structure in which the insertion protrusions 180 are continuously provided along the length of the belt body 110, providing a plurality of insertion protrusions 180 and arranging them separately facilitates the removal of the tower installation auxiliary tooling from the joint between the two tower sections.

[0077] In addition, the insertion protrusion 180 can also be configured as a thin sheet to facilitate extraction from the slurry.

[0078] In addition, if Figure 1 As shown, a hook ring 160 is further provided on the first surface of the belt body 110. When the tower installation auxiliary tooling needs to be disassembled from the tower section, the belt body 110 can be separated from the concrete tower section by hooking the hook ring 160 and applying force outwards.

[0079] The tower installation auxiliary tooling according to the embodiment of the present application also includes a removal rod. Figure 9As shown, the dismantling rod 400 includes a rod body 40 and a hook 43 connected to one end of the rod body 40. The hook 43 can be hooked to the shackle 160 to drive the belt body 110 away from the concrete tower section. The rod body 40 can also be configured as multiple, interconnectable sections to achieve a desired length and facilitate storage and transportation. The ends of two adjacent rods are provided with external and internal threads, respectively. By connecting multiple sections of the rod through threaded connections, the rod can be lengthened. Figure 9 An example is shown in which the rod body 40 includes a first rod body segment 41 and a second rod body segment 42 , but the present application is not limited thereto.

[0080] According to another aspect of the present application, a tower installation method is also provided. Figure 10 A flow chart of a tower installation method according to an embodiment of the present application is shown, referring to Figure 10 As shown, the tower installation method includes the following steps:

[0081] Step S110, installing the first tower section at a predetermined position;

[0082] Step S120, installing the aforementioned tower installation auxiliary tooling at the upper end of the first tower section;

[0083] Step S140, applying slurry on the upper surface of the first tower section;

[0084] Step S150: placing the second tower section on the slurry.

[0085] As mentioned above, the tower installation auxiliary tooling is formed as an annular member as a whole. In step S120, the tower installation auxiliary tooling can be installed on the radially inner side or outer side of the first tower segment, or can be installed on both the radially inner side and the radially outer side of the first tower segment. The annular member is then sleeved over the upper end of the first tower segment. When the tower installation auxiliary tooling is installed on the first tower segment, the lower edge of the annular member surrounds the outer circumference of the first tower segment, and the upper edge of the annular member is higher than the upper surface of the first tower segment.

[0086] It should be noted that the above step S120 can be performed before S110, that is, before the lower tower section is installed in place, a tower installation auxiliary tooling can be set at the upper end of the lower tower section.

[0087] For example, if the annular member is a rigid member and is generally annular, the annular member can be aligned with the first tower segment from above and lowered downwardly, such that the insertion protrusion 180 on the annular member rests on the upper surface of the first tower segment. If the annular member is formed by connecting multiple rigid arcuate segments, the multiple arcuate segments can be first connected to form an annular member and then installed from above the first tower segment. Alternatively, the multiple arcuate segments can be separately placed on the first tower segment and then connected to form an arcuate member.

[0088] In adopting Figure 1 In the illustrated tower installation auxiliary tooling, the belt 110 is positioned around the outer circumference of the upper end of the first tower segment and is sleeved onto the outer circumference of the upper end of the first tower segment by connecting the first connecting portion 120 and the second connecting portion 130. The lower edge of the belt 110 in the width direction surrounds the outer circumference of the upper end of the first tower segment, while the upper edge of the belt 110 is higher than the upper surface of the first tower segment.

[0089] In step S140, the blocking effect of the annular member reduces the amount of slurry overflowing from the top of the first tower section. Furthermore, the blocking effect of the annular member prevents large amounts of slurry from overflowing and falling when the second tower section is placed on top of the first tower section, ensuring that the gap between the first and second tower sections is fully filled with slurry. Furthermore, according to the tower installation method of the present application, applying the slurry after installing the annular auxiliary tooling facilitates smooth application of the slurry and maintains the slurry's adhesive properties, and can ensure the quality of adhesion when the upper tower section is placed on the lower tower section.

[0090] Furthermore, the tower installation method may further include step S130, where, after installing the tower installation auxiliary tooling and before applying the slurry, a leveling member is installed at the upper end of the first tower section. The leveling member adjusts the horizontality of the upper surface of the first tower section, thereby ensuring the verticality of the second tower section. In step S130, the leveling member is positioned to be approximately flush with, or slightly higher than, the height of the insertion protrusion 180.

[0091] According to the embodiment of the present application, the tower installation auxiliary tooling can be retained on the tower, which helps to enhance the connection quality of the tower. In addition, the tower installation auxiliary tooling can also be removed after the two tower sections are connected so that it can be reused when the next set of towers is connected. Figure 5 As shown, the tower installation method according to the embodiment of the present application may further include step S160 of removing the tower installation auxiliary tooling. Step S160 may be performed a predetermined time after the second tower section is installed on the first tower section (that is, before the slurry is completely solidified).

[0092] When the tower installation auxiliary tooling is disassembled, the annular component of the tower auxiliary tooling needs to have at least one opening to facilitate the opening of the annular component. Figure 1 In the case of the tower installation auxiliary tooling shown, in step S160, the first connecting part 120 and the second connecting part 130 are first loosened from each other, and then the belt body 110 is separated from the tower by pulling the hook ring 160 to facilitate the connection operation of the next tower section.

[0093] According to an embodiment of the present application, when the tower installation auxiliary tooling is set on the radial inner side or outer side of the first tower section, the joints of the tower sections are grouted on the side where the tower auxiliary tooling is not set, so that the slurry at the joints is filled evenly and fully to prevent the infiltration of external dust and rainwater, and at the same time, the outer surface is trimmed to make the outer surface of the tower neat and beautiful.

[0094] The following briefly describes, by way of example, a process of using the tower installation auxiliary tooling according to an embodiment of the present application during the process of interconnecting multiple tower segments.

[0095] First, use a crane to lift the first tower section to a predetermined position and fix it. When the first tower section is the lowest tower section, the lower end of the first tower section is connected to the tower foundation. When the first tower section is not the lowest tower section, the first tower section is fixedly connected to the tower section below it.

[0096] After the first tower segment is installed in its intended position, the band 110 is wrapped around the outer circumference of the upper end of the first tower segment, and the first and second connecting portions 120, 130 of the band 110 are connected to each other, thereby forming a closed hoop around the outer circumference of the upper end of the first tower segment. Since the insertion protrusion 180 is provided on the inner surface of the band 110, it can overlap the top of the first tower segment, thereby positioning the band 110 in the height direction of the tower and preventing it from falling downward.

[0097] According to an embodiment of the present application, since the belt body 110 includes multiple belt segments, that is, a first segment 100, a tail segment 200 and at least one intermediate segment 300 arranged between the first segment 100 and the tail segment 200, before the tower installation auxiliary tooling is set on the outer periphery of the upper end of the first tower segment, the required number of intermediate segments 300 is determined according to the circumference of the tower, and an appropriate number of intermediate segments 300 are selected. Then, the first segment 100, the intermediate segment 300, and the tail segment 200 are connected end to end in sequence to form a belt body 110 of appropriate length, and then the belt body 110 is surrounded by the upper end of the first tower segment.

[0098] After installing the tower installation auxiliary tooling, a leveling member is installed on top of the first tower section to ensure that the axis of the second tower section is perpendicular to the horizontal plane when it is installed on the first tower section. This ensures the verticality of the tower and prevents the tower from tilting, which could affect the overall safety of the wind turbine. In this application, by providing multiple insertion protrusions 180 rather than a continuous arrangement, they can be staggered with the leveling member to avoid interference with the installation of the leveling member.

[0099] After installing the leveling section, slurry is applied to the top of the first tower section and filled. In this application, because the belt 110 is sleeved around the outer periphery of the first tower section and the upper edge of the belt 110 is higher than the top of the first tower section, the slurry is prevented from overflowing and falling due to the blocking of the belt 110, thereby reducing slurry loss.

[0100] After the slurry is set, the second tower section is hoisted and lowered to rest on the slurry. Under the pressure of the second tower section, the excess slurry will be squeezed and overflow to both sides. However, in the present application, since the belt body 110 surrounds the outer circumference of the tower section, the squeezed slurry will not fall from the outside of the joint, and due to the blocking and squeezing effect exerted by the belt body 110, the slurry on the outside of the joint is fuller and more compact. At the same time, under the squeezing effect of the second tower section, the slurry flows to the inside of the joint, thereby filling the inner slurry, and then the excess slurry will be squeezed out from the inside.

[0101] After a predetermined time, the tower installation auxiliary tooling is removed. For example, the timing of removal can be determined based on the slurry's formation state. Once the slurry has formed and no more slurry is falling outward, the tower installation auxiliary tooling can be removed. The removal rod can be connected to an appropriate length, and the hook portion 43 can be used to pull the hook ring 160 to remove the tower installation auxiliary tooling.

[0102] The dismantled tower installation auxiliary tooling will be installed on the second tower section to carry out the connection operation of the next tower section.

[0103] When the tower installation auxiliary tooling according to the present application is used, the loss of slurry can be effectively reduced, and the slurry at the joints can be ensured to be full, thereby improving the connection quality of the tower.

[0104] Although the embodiments of the present invention have been described in detail above, those skilled in the art may make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope of the present invention. It should be understood that, in the opinion of those skilled in the art, such modifications and variations will still fall within the spirit and scope of the embodiments of the present invention as defined in the claims.
