Description

Technical Field

[0001] This application relates to the field of tube reshaping equipment technology, and particularly to a straightening tool. Background Technology

[0002] Before assembly, the flanges inside wind turbine towers are prone to deformation due to their significant weight and prolonged horizontal placement. Currently, straightening fixtures are used to straighten these flanges. Because the tower is cylindrical, the straightening fixtures can only be hoisted into the tower in a horizontal position (with the tower axis horizontal).

[0003] Because the tower is in a horizontal position, the flange may undergo elastic deformation due to its own weight, leading to inaccurate measurements of the flange's shape and dimensions (diameter). The straightening fixture cannot promptly verify the straightening effect during the flange straightening process. Utility Model Content

[0004] The purpose of this application is to provide a straightening fixture that can be assembled and the flange straightened when the tower is in a vertical position, so as to enable timely inspection of the straightening effect.

[0005] To achieve the above objectives, this application provides a straightening fixture for straightening flanges in a tower. The straightening fixture includes a straightening assembly, a support assembly, and a lifting device. The straightening assembly has a first abutment and a second abutment, which are located on opposite sides of the straightening assembly in a predetermined direction, and the distance between them in the predetermined direction is adjustable. The first and second abutments are respectively used to abut against the radial inner wall surface of the flange in the predetermined direction, which is the same as or inclined to the radial direction of the flange. The support assembly is used for detachably connecting to the flange and has a mounting portion. When the tower is placed vertically, the mounting portion is located inside the main body of the tower and above the flange. The lifting device is installed on the mounting portion and is used to lift the straightening assembly when the tower is placed vertically.

[0006] Optionally, the straightening fixture also includes fasteners; wherein the flange has a flange hole, the bracket assembly has a first mounting hole, and the fasteners are used to pass through the flange hole and the first mounting hole in sequence, and to detachably connect the bracket assembly to the flange.

[0007] Optionally, there may be multiple mounting parts, which are arranged radially spaced apart on the flange when the bracket assembly is connected to the flange.

[0008] Optionally, there may be multiple support assemblies, and when multiple support assemblies are connected to the flange respectively, at least two support assemblies are spaced apart in a predetermined direction.

[0009] Optionally, the support assembly includes multiple support units, multiple connecting beams, and multiple lifting lugs. Each support unit is detachably connected to the flange, and the multiple support units are spaced apart circumferentially on the flange. Each connecting beam is connected to multiple support units, and the multiple connecting beams are spaced apart radially on the flange. Lifting lugs correspond one-to-one with connecting beams, with each lug positioned on a corresponding connecting beam. Lifting devices are used to hang from the lifting lugs, which form the mounting portion.

[0010] Optionally, the support unit includes an upright, a crossbar, and a support rod. The upright is detachably connected to the flange and extends axially along the flange. The crossbar is connected to the upright and extends radially along the flange. The support rod is diagonally supported between the upright and the crossbar. A connecting beam connects to the crossbar.

[0011] Optionally, the connecting beam and the support unit can be detachably connected.

[0012] Optionally, the straightening fixture also includes a connector and a pin. The connector is connected to the straightening assembly and has a second mounting hole. The pin passes through the second mounting hole. The flange has a flange hole, and the pin also passes through the flange hole to allow the connector to be rotatably connected to the flange.

[0013] Optionally, the first abutment top is an arc-shaped surface, and the connector protrudes from the first abutment top and is located in an area outside the area where the first abutment top abuts with the flange; or, the second abutment top is an arc-shaped surface, and the connector protrudes from the second abutment top and is located in an area outside the area where the second abutment top abuts with the flange.

[0014] Optionally, the orthopedic assembly includes a first support member, a second support member, a drive cylinder, and a sheath. The second support member and the first support member are spaced apart in a predetermined direction. A first abutment is located on the side of the first support member opposite to the second support member in the predetermined direction, and a second abutment is located on the side of the second support member opposite to the first support member in the predetermined direction. The drive cylinder is located between the first and second support members in the predetermined direction. The drive cylinder includes a cylinder body and a piston rod. The cylinder body is connected to the first support member, and the piston rod is reciprocating relative to the cylinder body in the predetermined direction, and the piston rod is used to abut against the second support member. The sheath is connected to the second support member and forms a receiving cavity. When the piston rod abuts against the second support member, the piston rod and the end of the cylinder body closest to the second support member in the predetermined direction are respectively located within the receiving cavity.

[0015] The technical solution described in this application has the following advantages over the prior art:

[0016] The technical solution provided in this application involves a support assembly detachably connected to a flange. When the tower is in a vertical position, the mounting portion of the support assembly is located inside the tower and above the flange. A lifting device is installed at the mounting portion of the support assembly. Using the lifting device's lifting function, the straightening assembly can be lifted to a predetermined position on the flange, completing the assembly of the straightening assembly. The straightening assembly is then used to straighten the flange. In other words, the installation point for the lifting device is established inside the tower, allowing workers to assemble the straightening assembly inside the tower using the lifting device. In a vertical position, the weight of the tower acts axially on the flange, and the flange experiences minimal elastic deformation. The flange diameter measurement data accurately reflects the flange shape. Workers can adjust the straightening position and the degree of straightening based on the measurement data. Therefore, this application allows the straightening assembly to be assembled onto the flange and the flange to be straightened while the tower is in a vertical position, enabling timely verification of the straightening effect.

Detailed Implementation

[0030] Please see Figure 1 , Figure 1 This is a three-dimensional structural diagram of a wind turbine.

[0031] The wind turbine includes a tower 120, a nacelle 130, and a rotor 140. The tower 120 is fixed to a foundation 110 (the foundation 110 is, for example, an installation platform on the ground, seabed, or sea surface). The tower 120 supports the nacelle 130 and the rotor 140. The nacelle 130 and the rotor 140 are mounted on top of the tower 120. The electrical equipment required for the wind turbine, such as the generator, speed increaser, hydraulic system, and heat exchange system, are all housed in the nacelle 130 and supported by the tower 120.

[0032] Please refer to the following: Figure 2 , Figure 2 This is a cross-sectional view of tower 150.

[0033] Tower 120 comprises multiple tower sections 150. Each tower section 150 includes a cylindrical body 151 and two flanges 152 located at both ends of the body 151. Each flange 152 has multiple flange holes 153 spaced apart around the axis L of the tower section 150. Adjacent tower sections 150 are interconnected via flanges 152. Tower sections 150 are also connected to the foundation 110 and to the nacelle 130 via flanges 152.

[0034] The two flanges 152 located at both ends can be the same or different. Figure 2 In the tower 150 shown, the top flange 152 protrudes from the inner wall of the main body 151 and has a ring of flange holes 153 located radially inner to the main body 151. The bottom flange 152 protrudes from both the inner and outer surfaces of the main body 151 and has two rings of flange holes 153, one ring located radially inner to the main body 151 and the other ring located radially outer to the main body 151. The flange 152 is a conventional technique for mechanical connections, and this application does not involve any improvements to the flange 152.

[0035] With the tower 150 in a horizontal position (its axis L is horizontal), the flange 152 is subjected to radial force due to its own weight, making it prone to deformation, meaning its roundness does not meet installation requirements. In related technologies, due to structural limitations of the tower 150, the straightening fixture can only be installed and straightened in this horizontal position. Specifically, the process of assembling the straightening fixture into the flange 152 is as follows: with the tower 150 in a horizontal position, the flange 152 is open to one side in the horizontal direction. The straightening fixture is lifted using a lifting device and assembled into the flange 152 horizontally through the opening. However, with the tower 150 in a horizontal position, the measurement results of the flange 152's shape or dimensions are not accurate enough, making it impossible to promptly verify the straightening effect.

[0036] The following embodiments of this application enable the straightening fixture to be assembled onto the flange 152 while the tower 150 is in a vertical position, and the straightening fixture to straighten the flange 152, thereby enabling timely inspection of the straightening effect.

[0037] In the following text, unless otherwise stated, flange 152 refers to flange 152 located at the bottom when tower 150 is placed vertically, that is, flange 152 to be corrected.

[0038] Please see Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of using a straightening fixture according to an embodiment of this application to straighten the flange 152 of the tower 150. Figure 4 yes Figure 3 A magnified view of a partial view.

[0039] This application provides a straightening fixture for straightening a flange 152 in a tower 150. The straightening fixture includes a straightening assembly 210, a support assembly 220, and a lifting device 230. The straightening assembly 210 has a first abutment 215 and a second abutment 216, which are located on opposite sides of the straightening assembly 210 in a predetermined direction F, and the distance between them in the predetermined direction F is adjustable. The first abutment 215 and the second abutment 216 are respectively used to abut against the radial inner wall surface of the flange 152 in the predetermined direction F, which is the same as or inclined to the radial direction of the flange 152. The support assembly 220 is detachably connected to the flange 152 and has a mounting portion 270. When the tower 150 is placed vertically, the mounting portion 270 is located inside the main body 151 of the tower 150 and above the flange 152. The lifting device 230 is installed on the mounting section 270 and is used to lift the straightening component 210 when the tower 150 is placed vertically.

[0040] The tower cylinder 150 is the object of the straightening fixture, and includes a main body 151 and a flange 152. The tower cylinder 150 can be as described above. Figure 2 The structure shown can also be other structures, and this application does not limit it.

[0041] The orthopedic component 210 can be a single-piece structure or a separate structure. Figure 3 The orthotic component 210 shown is a modular structure, meaning it is assembled from multiple parts. The specific structure of the orthotic component 210 is described in detail below.

[0042] After the straightening component 210 is installed on the flange 152, the predetermined direction F is the same as or inclined to the radial direction of the flange 152. Specifically, the predetermined direction F has a radial component of the flange 152, or in other words, the change in the distance between the first abutment 215 and the second abutment 216 in the predetermined direction F can be reflected as a change in the distance in the radial direction of the flange 152.

[0043] exist Figure 3 In the illustrated embodiment, after the orthopedic assembly 210 is installed onto the flange 152, the predetermined direction F is the same as the radial direction of the flange 152. After the orthopedic assembly 210 is installed inside the flange 152, the radial distance between the first abutment 215 and the second abutment 216 on the flange 152 is adjustable.

[0044] Please see Figure 5 , Figure 5 This is a top view of the orthopedic component 210 installed in the flange 152 in another embodiment of this application.

[0045] exist Figure 5In the illustrated embodiment, there are two orthotic components 210, which are spaced apart and located on either side of the center O of the flange 152. After each orthotic component 210 is installed onto the flange 152, the predetermined direction F is inclined to the radial direction of the flange 152. After the orthotic components 210 are installed onto the flange 152, the change in the distance between the first abutment 215 and the second abutment 216 in the predetermined direction F can be reflected as a change in the distance in the radial direction of the flange 152.

[0046] Please continue reading. Figure 3 and Figure 4 Before assembling the straightening assembly 210, the first and second abutment positions P1 and P2 of the flange 152 are determined. For example, by measuring the diameter at different positions of the flange 152, the two positions with the smallest diameters are identified as the first abutment position P1 and the second abutment position P2. The diameters of the flange 152 at the first and second abutment positions P1 and P2 are designated as the first dimension. Before assembling the straightening assembly 210 to the flange 152, the dimensions of the first abutment 215 and the second abutment 216 in the predetermined direction F are adjusted to the second dimension. The second dimension is smaller than the first dimension. The first abutment 215 is aligned with the first abutment position P1, and the second abutment 216 is aligned with the second abutment position P2. Then, the dimensions of the first abutment 215 and the second abutment 216 in the predetermined direction F are adjusted to the third dimension, which is larger than the first dimension. In other words, by increasing the dimension F in the predetermined direction, the straightening component 210 pushes the flange 152 from the inside out at the smaller diameter, thereby restoring the shape of the flange 152.

[0047] The support assembly 220 is detachably mounted to the flange 152. Specifically, the connection between the support assembly 220 and the flange 152 can be located inside or outside the main body 151 of the tower 150, as long as the mounting portion 270 of the support assembly 220 is located inside the tower 150. Figure 3 In the illustrated embodiment, the connection between the support assembly 220 and the flange 152 is located inside the main body 151 of the tower 150, and the entire support assembly 220 is located inside the main body 151 of the tower 150. In an embodiment where the connection between the support assembly 220 and the flange 152 is located outside the main body 151 (not shown), at least a portion of the bottom of the tower 150 (flange 152) can be suspended, allowing the support assembly 220 to bypass the flange 152 through the bottom of the tower 150, thereby allowing the mounting portion 270 to enter the interior of the main body 151. For example, it can be adopted... Figure 3 In the illustrated embodiment, a pad 260 (e.g., a sleeper) is placed at the bottom of the tower 150. Figure 3In the embodiment shown, the function of the pad 260 is to suspend the bottom of the tower 150, making it easier for workers to enter and exit the tower 150.

[0048] The lifting device 230 can be a manual hoist, electric hoist, etc. The lifting device 230 is installed inside the main body 151 of the tower 150 and suspended above the flange 152. The lifting device 230 can be a small-sized lifting device for easy operation by workers.

[0049] In one application scenario, the process of shaping flange 152 is as follows:

[0050] Place pad 260; use lifting equipment to vertically place tower 150 so that tower 150 is supported on pad 260; install bracket assembly 220 on flange 152; install lifting device 230 on mounting part 270 of bracket assembly 220; use lifting device 230 to lift straightening assembly 210 and assemble straightening assembly 210 to flange 152; straighten flange 152 by straightening assembly 210.

[0051] The technical solution provided in this application involves a support assembly 220 detachably connected to a flange 152. When the tower 150 is in a vertical position, the mounting portion 270 of the support assembly 220 is located inside the tower 150 and above the flange 152. A lifting device 230 is installed at the mounting portion 270 of the support assembly 220. Using the lifting function of the lifting device 230, the straightening assembly 210 can be lifted to a predetermined position on the flange 152, completing the assembly of the straightening assembly 210. Then, the straightening assembly 210 is used to straighten the flange 152. In other words, the mounting point of the lifting device 230 is established inside the tower 150, allowing workers to assemble the straightening assembly 210 inside the tower 150 using the lifting device 230. In a vertical position, the weight of the tower 150 acts axially on the flange 152, and the flange 152 essentially does not undergo elastic deformation. The measured diameter data of the flange 152 accurately reflects its shape. Based on the test data, operators can adjust the correction position and correction range of flange 152 in a timely manner. Therefore, this application enables the correction component 210 to be assembled onto flange 152 and the flange 152 to be corrected when tower 150 is in a vertical position, thereby enabling timely inspection of the correction effect.

[0052] Please see Figure 6 , Figure 6 This is a three-dimensional structural diagram of the bracket assembly 220 and the fastener 240 in one embodiment of this application.

[0053] In some embodiments, the orthopedic fixture further includes a fastener 240. The flange 152 has a flange hole 153, and the bracket assembly 220 has a first mounting hole 2214. The fastener 240 is sequentially inserted through the flange hole 153 and the first mounting hole 2214, and detachably connects the bracket assembly 220 to the flange 152.

[0054] Specifically, in Figure 3 In the illustrated embodiment, flange 152 has a ring of flange holes 153 located inside body 151. Support assembly 220 has multiple first mounting holes 2214. The number of fasteners 240 is also multiple. The illustrated support assembly 220 has four first mounting holes 2214, corresponding to four fasteners 240. After the first mounting holes 2214 are aligned (coaxially arranged) with the flange holes 153, the fasteners 240 pass through the aligned first mounting holes 2214 and flange holes 153, locking the support assembly 220 to flange 152. Specifically, the fasteners 240 include bolts and nuts. The bolts pass through the aligned first mounting holes 2214 and flange holes 153, and the nuts are screwed onto the bolts, engaging with the bolt heads to clamp the support assembly 220 and flange 152 axially.

[0055] In this embodiment, the inherent connection function of the flange 152 is fully utilized. The support assembly 220 is detachably connected to the flange 152 by fasteners 240. No additional processing is required on the tower 150 to securely connect the support assembly 220 to the flange 152.

[0056] In some other embodiments, the bracket assembly 220 can also be detachably connected to the flange 152 by means of snap-fit, clamping, or other methods.

[0057] Please see Figure 3 and Figure 4 In some embodiments, there are multiple mounting portions 270, which are arranged radially spaced apart when the bracket assembly 220 is connected to the flange 152. Figure 3 In the illustrated embodiment, the bracket assembly 220 has two mounting portions 270, which are radially spaced apart from each other on the flange 152.

[0058] The lifting device 230 can be selectively installed on one of the mounting parts 270. Since multiple mounting parts 270 are provided and are spaced apart radially on the flange 152, the installation position of the lifting device 230 can be switched radially on the flange 152 as needed, thereby facilitating the lifting of the straightening assembly 210.

[0059] In this embodiment, there may be multiple lifting devices 230, with each lifting device 230 corresponding to a mounting part 270, and each lifting device 230 being installed on the corresponding mounting part 270.

[0060] In some embodiments, there are multiple bracket assemblies 220, and when multiple bracket assemblies 220 are respectively connected to flange 152, at least two bracket assemblies 220 are spaced apart in a predetermined direction F. Figure 3 In the illustrated embodiment, there are two bracket assemblies 220, which are arranged radially spaced apart on the flange 152.

[0061] The lifting device 230 can be selectively mounted on the mounting portion 270 of one of the support components 220, thereby allowing the lifting device 230 to selectively lift the orthotic component 210 at different locations.

[0062] In this embodiment, there can be multiple lifting devices 230, with each lifting device 230 corresponding to a support assembly 220, and each lifting device 230 is installed on the mounting part 270 of the corresponding support assembly 220. Since multiple support assemblies 220 are provided, at least two support assemblies 220 are spaced apart in a predetermined direction F, allowing simultaneous lifting at both ends of the orthopedic assembly 210.

[0063] In some embodiments, there are multiple bracket assemblies 220. When multiple bracket assemblies 220 are respectively connected to flange 152, at least two bracket assemblies 220 are spaced apart in a predetermined direction F. Each bracket assembly 220 has multiple mounting portions 270. When a bracket assembly 220 is connected to flange 152, the multiple mounting portions 270 are spaced apart radially on flange 152. The number of lifting devices 230 can be set as needed.

[0064] Please see Figure 6 In some embodiments, the bracket assembly 220 includes a plurality of support units 221, a plurality of connecting beams 222, and a plurality of lifting lugs 223. Each support unit 221 is detachably connected to a flange 152, and the plurality of support units 221 are spaced apart circumferentially on the flange 152. Each connecting beam 222 is connected to a plurality of support units 221, and the plurality of connecting beams 222 are spaced apart radially on the flange 152. Each lifting lug 223 corresponds to a connecting beam 222, and each lifting lug 223 is disposed on a corresponding connecting beam 222. A lifting device 230 is used to hang on the lifting lug 223, and the lifting lug 223 forms a mounting portion 270. Specifically, in Figure 6 In the illustrated embodiment, there are two support units 221, two connecting beams 222, and two lifting lugs 223. When the bracket assembly 220 is detachably connected to the flange 152 via the first mounting hole 2214, the first mounting hole 2214 can be formed in the support unit 221, and the support unit 221 is detachably connected to the flange 152 via the first mounting hole 2214.

[0065] The bracket assembly 220 adopts a frame structure, which can effectively reduce its own weight while ensuring structural strength, making it convenient for operators to install it onto the flange 152.

[0066] In some embodiments, the support unit 221 includes an upright 2211, a crossbar 2212, and a support rod 2213. The upright 2211 is detachably connected to the flange 152 and extends axially in the flange 152. The crossbar 2212 is connected to the upright 2211 and extends radially in the flange 152. The support rod 2213 is diagonally supported between the upright 2211 and the crossbar 2212. A connecting beam 222 is connected to the crossbar 2212.

[0067] Specifically, when the support unit 221 is detachably connected to the flange 152 through the first mounting hole 2214, the first mounting hole 2214 can be opened in the upright 2211, and the upright 2211 is detachably connected to the flange 152 through the first mounting hole 2214.

[0068] Specifically, the bottom end of the upright 2211 is supported on the top surface of the flange 152, and the crossbar 2212 extends radially inward from the top end of the upright 2211 in the flange 152. One end of the support rod 2213 is connected to the upright 2211, and the other end is connected to the crossbar 2212.

[0069] In this embodiment, the support unit 221 also adopts a frame structure, which can effectively reduce its own weight while ensuring structural strength, making it convenient for operators to install it onto the flange 152.

[0070] In some embodiments, the connecting beam 222 is detachably connected to the support unit 221. For example, the connecting beam 222 and the support unit 221 are connected by bolts. The bracket assembly 220 adopts a split structure, and the size and weight of each component are significantly reduced compared to the bracket assembly 220 with an integral structure, making it easier for operators to handle and install.

[0071] Please see Figure 7 and Figure 8 , Figure 7 This is a three-dimensional structural schematic diagram of the orthopedic component 210 from a first-view perspective in one embodiment of this application. Figure 8 This is a three-dimensional structural schematic diagram of the orthopedic component 210 from a second perspective in one embodiment of this application.

[0072] In some embodiments, the orthopedic fixture further includes a connector 252 and a pin 251. The connector 252 is connected to the orthopedic assembly 210 and has a second mounting hole 2521. The pin 251 passes through the second mounting hole 2521. The flange 152 has a flange hole 153, and the pin 251 also passes through the flange hole 153 to allow the connector 252 to be rotatably connected to the flange 152.

[0073] Specifically, in Figure 7 , Figure 8 In the illustrated embodiment, the orthotic assembly 210 is provided with a connector 252 and a pin 251 at both ends in the predetermined direction F. That is, both ends of the orthotic assembly 210 in the predetermined direction F can be rotatably connected to the flange 152.

[0074] In this embodiment, by setting the connector 252 and the pin 251, the end of the straightening fixture is rotatably connected to the flange 152, ensuring that the flange 152 will not suddenly deform during the straightening process (during the application of top support force) and cause a major accident. At the same time, the relative posture of the straightening fixture and the flange 152 can also be adaptively adjusted, that is, a small angular offset can be generated between the two, so that the straightening effect is better.

[0075] In some embodiments, the first abutment 215 is an arcuate surface, and the connector 252 protrudes from the first abutment 215 and is located outside the area where the first abutment 215 abuts against the flange 152. Specifically, the first abutment 215 is an arcuate surface that matches the shape of the radial inner wall surface of the flange 152. A portion of the first abutment 215 abuts against the flange 152. The connector 252 is generally flat and perpendicular to the axis L of the flange 152. When the first abutment 215 abuts against the inner wall surface of the flange 152, the connector 252 is located above the flange 152.

Specifically, the second abutment 216 is an arcuate surface that matches the shape of the radial inner wall surface of the flange 152. A portion of the second abutment 216 abuts against the flange 152. The connector 252 is generally flat and perpendicular to the axis L of the flange 152. When the second abutment 216 abuts against the inner wall surface of the flange 152, the connector 252 is positioned above the flange 152.

[0077] Please refer to the following: Figure 9 , Figure 9 This is a schematic diagram of the drive cylinder 213 in one embodiment of this application.

[0078] In some embodiments, the orthopedic assembly 210 includes a first support member 211, a second support member 212, and a drive cylinder 213. The second support member 212 is spaced apart from the first support member 211 in a predetermined direction F. A first abutment 215 is located on the side of the first support member 211 opposite to the second support member 212 in the predetermined direction F, and a second abutment 216 is located on the side of the second support member 212 opposite to the first support member 211 in the predetermined direction F. The drive cylinder 213 is located between the first support member 211 and the second support member 212 in the predetermined direction F. The drive cylinder 213 includes a cylinder body 2131 and a piston rod 2132. The cylinder body 2131 is connected to the first support member 211, and the piston rod 2132 is reciprocating relative to the cylinder body 2131 in the predetermined direction F. The piston rod 2132 is used to abut against the second support member 212.

[0079] The drive cylinder 213 is, for example, a hydraulic cylinder (jack). The piston rod 2132 of the drive cylinder 213 extends out and can drive the second support member 212 away from the first support member 211, thereby increasing the distance between the first abutment 215 and the second abutment 216 in a predetermined direction F.

[0080] In some embodiments, the orthopedic assembly 210 further includes a sheath 214. The sheath 214 is connected to the second support member 212 and forms a receiving cavity. When the piston rod 2132 abuts against the second support member 212, the piston rod 2132 and the cylinder body 2131 are respectively located in the receiving cavity at one end of the piston rod 2132 and the other end of the cylinder body 2131 in a predetermined direction F near the second support member 212.

[0081] In this embodiment, by providing a protective sleeve 214, it is possible to prevent the drive cylinder 213 from accidentally separating from the second support member 212 during the application of the supporting force.

[0082] In some embodiments, the first support member 211 includes a first push rod 2111 and a second push rod 2112. The first push rod 2111 and the second push rod 2112 are arranged sequentially in a predetermined direction F and are detachably connected. The cylinder body 2131 of the drive cylinder 213 is detachably connected to the second push rod 2112. A first abutment 215 is disposed at the end of the first push rod 2111 opposite to the second push rod 2112.

[0083] By replacing the second push rod 2112 with one of different lengths, the straightening assembly 210 can be adapted to flanges 152 of different specifications.

[0084] Please see Figure 10 , Figure 10 This is a schematic diagram of the structure of the orthopedic component 210 in another embodiment of this application.

[0085] In some embodiments, the orthopedic assembly 210 includes a first support member 211, a second support member 212, and a motor 217. The second support member 212 is helically coupled to the first support member 211 about a predetermined direction F. This helical coupling is configured such that the second support member 212 and the first support member 211 can rotate relative to each other to move relative to each other in the predetermined direction F. A first abutment 215 is located on the side of the first support member 211 opposite to the second support member 212 in the predetermined direction F, and a second abutment 216 is located on the side of the second support member 212 opposite to the first support member 211 in the predetermined direction F. The motor 217 drives the first support member 211 and the second support member 212 to rotate relative to each other, thereby adjusting the relative positions of the first abutment 215 and the second abutment 216 in the predetermined direction F.

[0086] The straightening component 210 can be adjusted in length in a predetermined direction F to support the flange 152. The straightening component 210 can also have other structural forms, which will not be described in detail here.

[0087] The above embodiments can be combined with each other without conflict.

[0088] Please see Figure 3 , Figure 4 , Figures 6-9 The following is a detailed introduction. Figure 3 The embodiment shown illustrates the installation process of the orthopedic fixture and the orthopedic process.

[0089] The installation process is as follows:

[0090] The tower 150 is placed on top of the pad 260 using a crane;

[0091] Install the two support units 221 in the bracket assembly 220 onto the flange 152 respectively, that is, lock the support unit 221 onto the flange 152 by fastener 240;

[0092] Install the two connecting beams 222 in the bracket assembly 220 onto the two support units 221 respectively;

[0093] Hang the lifting device 230 onto the lifting lug 223 in the bracket assembly 220;

[0094] The first top rod 2111 in the first top support 211 is lifted by the lifting device 230;

[0095] The first push rod 2111 in the first support member 211 is fixed to the flange 152 by the pin 251;

[0096] The second top support component 212 is lifted using the lifting device 230;

[0097] The second support member 212 is fixed to the flange 152 by another pin 251;

[0098] The second push rod 2112 in the first top support 211 is lifted by the lifting device 230, and then the second push rod 2112 is connected to the first push rod 2111;

[0099] The drive cylinder 213 is lifted by the lifting device 230, and then the cylinder body 2131 of the drive cylinder 213 is connected to the second push rod 2112;

[0100] Install the sheath 214 onto the second support member 212.

[0101] Working process: The operation of the drive cylinder 213 causes the piston rod 2132 to extend and push against the second support member 212, so that the first abutment 215 and the second abutment 216 respectively push against the radial inner wall surface of the flange 152.

[0102] In this application, the flange is straightened while the tower is vertically positioned, allowing for timely and rapid verification of the straightening effect. Repeated pressurization and depressurization operations enable timely checking of the deformation repair amount, thus controlling the ejection process of the drive cylinder. This application is more suitable for the actual needs of hoisting sites. Drive cylinder operation is a highly dangerous activity, with hydraulic pressure reaching tens of megapascals.
