Description

Technical Field

[0001] The utility model relates to the technical field of installation of wind turbine generators, and particularly relates to a fixing device and an installation device for wind turbine generators. Background Art

[0002] With the increasingly fierce competition in the wind power industry and the concept of equal price of thermal power and wind power, it is imperative to reduce the manufacturing cost while ensuring the product quality of wind turbine generators. In the commonly used steel-concrete structure tower of high tower turbines, the cost of steel and concrete is very considerable. At the same time, during the hoisting process of wind turbine generators, it is necessary to prevent vortex-induced vibration, that is, according to the results of simulation calculations, spoiler devices are manually installed on the upper several sections of the tower barrel. This method has many disadvantages such as high cost, unsatisfactory spoiler effect, cumbersome installation method of the spoiler device, and certain safety risks in the removal of the spoiler device. The truss tower can greatly reduce the usage of steel and concrete, reduce the cost of the tower part in the wind turbine generator, and the wind can be disrupted after passing through the truss tower, and can prevent vortex-induced vibration in all directions. Therefore, the truss tower has begun to gradually replace the conventional steel tower.

[0003] At present, the installation devices of wind turbine generators can only meet the installation of steel-concrete structure towers and cannot be used for the installation of truss towers. For those skilled in the art, it is an urgent technical problem to provide a device that can simultaneously meet the installation of steel towers and truss towers. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a fixing device and an installation device for wind turbine generators, which can simultaneously meet the installation of steel towers and truss towers.

[0005] To solve the above technical problems, the utility model provides a fixing device, including:

[0006] A support base, on the upper side wall of which a guide rail is connected;

[0007] Two clamping devices, which are slidably installed on the support base through the guide rail, and clamping walls are arranged oppositely on the two clamping devices;

[0008] A driving unit, which is connected with the clamping device, and the driving unit is used to drive the two clamping devices to approach or move away from each other relatively, so as to clamp or loosen the upright column of the truss tower through the clamping wall.

[0009] When the fixing device of the utility model is applied to the installation equipment of the wind turbine generator set, the number of the fixing devices is equal to the number of columns in the truss tower. In each fixing device, the support base plays a supporting role, and the guide rail plays a guiding role, so that the two clamping devices can only slide along the extension direction of the guide rail. The driving unit is used to drive the clamping device to move so that the two clamping devices are relatively close to or relatively far away from each other. When the driving unit drives the two clamping devices to be relatively close to each other, the two clamping walls can clamp the corresponding columns of the truss tower, which is convenient for the installation of the truss tower and the upper structure of the unit; when the upper truss tower is installed, the driving unit drives the two clamping devices to be relatively far away from each other, and the two clamping walls loosen the columns of the upper truss tower to install the next truss tower, and repeat the installation steps until the installation of the entire unit is completed.

[0010] It can be seen that when the fixing device of the utility model is applied to the installation equipment of the wind turbine generator set, it can meet the installation requirements of the truss tower. During the installation process of the truss tower, there is no need to install additional spoilers, which reduces costs, eliminates the installation and removal process of the spoilers, improves work efficiency, and avoids possible safety risks during the removal of the spoilers.

[0059] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0060] As used herein, "a plurality of" generally means more than two; and when "a plurality of" is used to represent the quantity of several components, it does not represent the mutual relationship in quantity of these components.

[0061] Please refer to Figure 1 And Figure 2 , Figure 1 which is a schematic structural diagram of a specific embodiment of the fixing device provided by the present invention when applied to the installation equipment of a wind turbine generator; Figure 2 And Figure 1 is a partial structural schematic diagram of

[0062] The present invention provides a fixing device 1, including:

[0063] A support base 11, and a guide rail 12 is connected to the upper side wall of the support base 11;

[0064] Two clamping devices 13, the two clamping devices 13 are slidably mounted on the support base 11 through the guide rails 12, and the two clamping devices 13 are provided with clamping walls 131 oppositely;

[0065] A driving unit 14, the driving unit 14 is connected to the clamping device 13, and the driving unit 14 is used to drive the two clamping devices 13 to approach or move away from each other relatively, so as to clamp or loosen the column of the truss tower (i.e., the truss tower) through the clamping wall 131.

[0066] When the fixing device 1 of the present utility model is applied to the installation equipment of the wind turbine generator set, the number of the fixing devices 1 is equal to the number of the columns in the truss tower. In this embodiment, the number of the columns is three and they form a triangular structure. Therefore, as Figure 1 shown, in this embodiment, the number of the fixing devices 1 is also three, and the three fixing devices 1 form a triangular structure. Each fixing device 1 is used to fix one column of the truss tower; in each fixing device 1, the support base 11 plays a supporting role, and the guide rail 12 plays a guiding role, so that the two clamping devices 13 can only slide along the extending direction of the guide rail 12. The driving unit 14 is used to drive the clamping device 13 to move, so that the two clamping devices 13 approach or move away from each other relatively. When the driving unit 14 drives the two clamping devices 13 to approach each other relatively, the two clamping walls 131 can clamp the corresponding column of the truss tower, which is convenient for the installation of the truss tower and the upper structure of the unit; after the upper truss tower is installed, the driving unit 14 drives the two clamping devices 13 to move away from each other relatively, and the two clamping walls 131 loosen the column of the upper layer of the truss tower for the installation of the lower layer of the truss tower. Repeat the installation steps until the installation of the entire unit is completed.

[0067] It can be seen that when the fixing device 1 of the present utility model is applied to the installation equipment of the wind turbine generator set, it can meet the installation of the truss tower. During the installation process of the truss tower, there is no need to install additional spoiler devices, which reduces costs, eliminates the installation and removal processes of the spoiler devices, improves work efficiency, and avoids potential safety risks during the removal process of the spoiler devices.

[0068] Please continue to refer to Figures 2 - 3 , Figure 3 which is Figure 1 the structural schematic diagram of the clamping device in the fixing device.

[0069] In this embodiment, the clamping device 13 further includes a positioning pin 132, and the positioning pin 132 is connected to one of the clamping walls 131.

[0070] In this way, the positioning pin 132 can cooperate with the positioning hole on the column of the truss tower, making the connection between the fixing device 1 and the truss tower more stable and reliable, and avoiding the situation that the truss tower slides along the clamping wall 131.

[0071] FromFigure 2 With Figure 3 It can be seen that in this embodiment, the number of the positioning pins 132 is one, and the positioning pin 132 is connected to one of the clamping walls 131. In practice, the number of the positioning pins 132 can be multiple, and when the number of the positioning pins 132 is multiple, the positioning pins 132 can be arranged on the same clamping wall 131 or on two clamping walls 131.

[0072] From Figure 2 With Figure 3 It can be seen that in this embodiment, the positioning pin 132 is of a cylindrical structure. From the middle of the positioning pin 132 towards the free end, the diameter of the positioning pin 132 gradually decreases, which is convenient for the positioning pin 132 to be inserted into the corresponding positioning hole. In practice, the shape of the positioning pin 132 is not limited. For example, the cross-section of the positioning pin 132 can also be square, etc.

[0073] From Figure 2 With Figure 3 It can be seen that in this embodiment, the clamping wall 131 is of an arc-shaped structure. In practice, the clamping wall 131 should be designed by copying the shape of the column of the truss tower so that the clamping wall 131 can fit the peripheral wall of the column during operation.

[0074] In this embodiment, the cross-section of the guide rail 12 is in the shape of a capital "I". Specifically, the guide rail 12 includes an upper wall portion and a lower wall portion which are arranged oppositely, and a connecting portion connecting the upper wall portion and the lower wall portion. The lower wall portion is used for fixedly connecting with the support base 11 to improve the connection stability between the guide rail 12 and the support base 11. The lower side wall of the upper wall portion forms a first limiting wall facing the lower end. As Figure 3 shown, a T-shaped groove 13a is arranged on the lower side wall of the clamping device 13. The T-shaped groove 13a includes a first groove portion 13a1 close to the closed end and a second groove portion 13a2 close to the open end. The lower side wall of the first groove portion 13a1 forms a second limiting wall B facing the upper end. The upper end of the guide rail 12 is movably inserted into the T-shaped groove 13a. Specifically, the upper wall portion is movably inserted into the first groove portion 13a1. The upper side wall of the upper wall portion is in contact with the upper side wall of the first groove portion 13a1. The thickness of the upper wall portion can be less than the thickness of the first groove portion 13a1. At this time, there is a gap between the first limiting wall and the second limiting wall B. The thickness of the upper wall portion can also be equal to the thickness of the first groove portion 13a1. At this time, the first limiting wall and the second limiting wall B are in corresponding contact, and at least part of the connecting portion is located in the second groove portion 13a2.

[0075] With the above settings, the guide rail 12 and the clamping device 13 are limitedly connected in both the width direction and the height direction of the guide rail 12, ensuring that the guide rail 12 and the clamping device 13 can only move in the extending direction of the guide rail 12 and preventing the clamping device 13 from disengaging from the guide rail 12.

[0076] It can be understood that in practice, the shape of the guide rail 12 is not limited to the above embodiments. For example, the cross-section of the guide rail 12 can also be an inverted trapezoid, and a trapezoidal groove matching the lower side wall of the clamping device 13 is provided.

[0077] As can be seen from Figure 3 In this embodiment, the clamping device 13 further includes a main body portion 133, and the T-shaped groove 13a is provided on the lower side wall of the main body portion 133.

[0078] Please continue to refer to Figure 2 , in this embodiment, the support base 11 includes two support beams 111 arranged in parallel. Connecting seats are provided at both ends of the support beam 111. The number of guide rails 12 is two. The guide rails 12 are connected to the two support beams 111. The two guide rails 12 are spaced apart along the length direction of the support beam 111. Two guide grooves are provided on the lower side wall of the clamping device 13, that is, the aforementioned T-shaped grooves 13a. The guide grooves and the guide rails 12 are arranged in one-to-one correspondence.

[0079] With the above arrangement, the connecting seats at both ends of the support beam 111 are used to connect with the connecting beam 32 in the installation equipment of the wind turbine generator. The stable installation of the two clamping devices 13 is realized through the two support beams 111 and the two guide rails 12, and the structure is simple.

[0080] It can be understood that in practice, it is also feasible that the support base 11 is an integral annular plate-like structure, which can also play a supporting role.

[0081] In addition, as can be seen from Figure 2 In this embodiment, the driving unit 14 includes four driving members. Each clamping device 13 is connected to two driving members. The driving member can be in the structural form of a hydraulic cylinder / a pneumatic cylinder / an electric cylinder, etc. The cylinder body of the hydraulic cylinder / pneumatic cylinder / electric cylinder is hinged to the connecting beam 32 on the corresponding side, and the push rod of the hydraulic cylinder / pneumatic cylinder / electric cylinder is hinged to the clamping device 13. The extension or retraction of the push rod of the hydraulic cylinder / pneumatic cylinder / electric cylinder can drive the clamping device 13 to slide along the extension direction of the guide rail 12.

[0082] Of course, in practice, the number of driving members is not limited, and each clamping device 13 can be connected to at least one driving member.

[0083] Please refer to Figure 4 , Figure 4 is a schematic structural diagram of a specific embodiment of the installation equipment of the wind turbine generator provided by the present invention.

[0084] The present invention also provides an installation equipment of a wind turbine generator, including an equipment frame 2, a lifting mechanism 3 and a power mechanism. The number of equipment frames 2 is three, and the equipment frames 2 are arranged circumferentially to form a triangular structure;

[0085] The lifting mechanism 3 includes three lifting platforms 31 and connecting beams 32. The lifting platforms 31 are sleeved on the outer periphery of the corresponding equipment frames 2, and the connecting beams 32 connect two adjacent lifting platforms 31 together. The power mechanism is used to drive the lifting mechanism 3 to move along the axial direction of the equipment frame 2;

[0086] It also includes three of the aforementioned fixing devices 1. The fixing devices 1 are arranged at corresponding positions of the lifting platforms 31. The support bases 11 in the fixing devices 1 are connected to the upper side walls of the corresponding two connecting beams 32.

[0087] The installation equipment of the wind turbine generator set of the present utility model includes the aforementioned fixing device 1, so it has the same technical effects as the aforementioned fixing device 1, which will not be elaborated here.

[0088] It can be understood that in practice, the numbers of the equipment frame 2, the lifting platform 31 and the fixing device 1 are not limited. The number of the equipment frames 2 can be more than three. The numbers of the lifting platforms 31 and the fixing devices 1 are consistent with the number of the equipment frames 2. For example, if the number of the equipment frames 2 is four, the four equipment frames 2 are arranged circumferentially to form a square structure. The lifting platforms 31 are sleeved on the outer periphery of the corresponding equipment frames 2. The four fixing devices 1 are arranged at corresponding positions of the lifting platforms 31, and the four fixing devices 1 also form a square structure.

[0089] Among them, as described above, in this embodiment, the support base 11 is connected to the corresponding connecting beam 32 through connecting parts such as bolts, that is, the support base 11 and the connecting beam 32 adopt a detachable connection method.

[0090] In this way, when the wind turbine generator set adopts a truss tower, it can be installed through the fixing device 1. When the wind turbine generator set adopts a steel-concrete structure tower, the fixing device 1 can be detached and installed through the corresponding tower barrel fixing device, avoiding the interference of the fixing device 1 on the action of the tower barrel fixing device, so that the installation equipment of the wind turbine generator set of the present utility model can meet the installation of both the steel-concrete structure tower and the truss tower at the same time, expanding the application range of the installation equipment of the wind turbine generator set of the present utility model.

[0091] From Figure 4 It can be seen that in this embodiment, the power mechanism includes three power components. The power components are connected to the corresponding lifting platforms 31. The power components include four power units 4. The power units 4 are hydraulic cylinders, air cylinders or electric cylinders. Specifically, the hydraulic cylinders, air cylinders or electric cylinders extend along the axial direction of the equipment frame 2. The cylinder bodies of the hydraulic cylinders, air cylinders or electric cylinders are connected to the base 21 of the equipment frame 2. The push rods of the hydraulic cylinders, air cylinders or electric cylinders are connected to the corresponding lifting platforms 31. The extension or retraction of the push rods of the hydraulic cylinders, air cylinders or electric cylinders can drive the lifting platforms 31 to rise or fall.

[0092] As described above, the three power components act synchronously to ensure the smooth movement of the lifting mechanism 3 during the installation process; the power unit 4 adopts the structural form of a hydraulic cylinder, a pneumatic cylinder or an electric cylinder, which is more convenient for controlling the lifting action of the lifting mechanism 3 and improving the movement accuracy of the lifting mechanism 3.

[0093] In this embodiment, the power mechanism includes three power components. In practice, the number of power components is consistent with the number of lifting platforms 31. Therefore, the number of power components can also be more than three.

[0094] In this embodiment, each power component includes four power units 4. In practice, the number of power units 4 included in each power component is not limited. For example, each power component can include at least one power unit 4, as long as the lifting mechanism 3 has sufficient driving force.

[0095] From Figure 4 It can be seen that in this embodiment, the equipment frame 2 is a square frame structure. In practice, the structure of the equipment frame 2 is not limited. For example, the equipment frame 2 can also be a triangular frame structure, etc.

[0096] Please continue to refer to Figure 4 , in this embodiment, four adjusting seats 22 are installed along the circumferential direction at the lower end of the base 21 of the equipment frame 2. The adjusting seats 22 are axially telescopic along the equipment frame 2, and an inclination sensor is further included. The inclination sensor is arranged on the lifting mechanism 3.

[0097] In this way, the horizontal adjustment of the entire installation equipment can be realized through a total of twelve adjusting seats 22 at the lower ends of the three bases 21, and the inclination angle of the installation equipment during the fan installation process is monitored in real time through the inclination sensor to ensure the safety during the operation process.

[0098] Among them, the adjusting seat 22 can adopt the structural form of a hydraulic cylinder, a pneumatic cylinder, an electric cylinder, etc., which is convenient for control.

[0099] Among them, the inclination sensor is arranged on the lifting mechanism 3. Specifically, it can be arranged on the lifting platform 31 or on the connecting beam 32.

[0100] In this embodiment, four adjusting seats 22 are installed at the lower end of each base 21. In practice, the number of adjusting seats 22 installed at the lower end of each base 21 is not limited. For example, the number of adjusting seats 22 installed at the lower end of each base 21 can be more than three to ensure the stability of the equipment frame 2.

[0101] Please refer to Figure 4 , in this embodiment, the equipment frame 2 further includes three top covers 23 and three tension rods A. The two ends of the tension rod A are connected to adjacent two top covers 23. The three tension rods A form a triangular structure, making the overall stability of the installation equipment better.

[0102] It can be understood that in practice, the number of the tension rods A is not limited, and the number of the tension rods A can be more than three. For example, when the number of the equipment frames 2 is four, the number of the tension rods A is also four. The tension rods A are connected between two adjacent equipment frames 2, and the four tension rods A enclose a square structure.

[0103] Please refer to Figure 4 , in this embodiment, two interconnected connecting beams 32 are connected between two adjacent lifting platforms 31 to form an integral body.

[0104] In this way, the connecting beam 32 and the lifting platform 31 form a closed triangular structure. The formation of multiple triangular structures makes the stability performance of the entire installation equipment better. At the same time, connecting the lifting platforms 31 together through the connecting beam 32 also ensures the synchronization of the lifting platforms 31 during the up and down movement. In addition, the connecting beam 32 serves as a carrier for many accessories, such as the fixing device 1, etc. Each accessory is installed on the connecting beam 32 to realize their respective required functions during the installation process of the wind turbine.

[0105] In this embodiment, the connecting beam 32 has an "I"-shaped structure. The two side walls of the connecting beam 32 form limiting grooves, which play a guiding role for the lifting mechanism 5 (to be described in detail later). The lifting mechanism 5 can move along the axial direction of the connecting beam 32, and the position adjustment during the installation process of the truss tower is realized by the movement of the lifting mechanism 5 on the connecting beam 32.

[0106] Please refer to Figure 5 , Figure 5 For Figure 4 a schematic structural diagram of one of the equipment frames and the corresponding lifting platform in the installation equipment of the wind turbine generator set.

[0107] In this embodiment, the lifting platform 31 includes a square cylinder 311 located at the upper part and an annular plate 312 fixedly sleeved on the lower end of the outer periphery of the cylinder 311. Three wall surfaces of the cylinder 311 are of a frame structure, and the remaining one wall surface adopts a closed plate-like structure. A connecting structure is provided on the plate-like structure for connecting the tower barrel fixing device 6 (to be introduced in detail later). Guide wheels are arranged inside the cylinder 311, and the guide wheels are used to cooperate with the guiding parts arranged on the equipment frame 2 to realize the guiding during the movement of the lifting platform 31 and make the lifting process of the lifting platform 31 smoother.

Specifically, the tower barrel fixing device 6 includes an upper support cross beam 61 and a lower support cross beam 62. The lower support cross beam 62 is connected to the inner wall of the lifting platform 31, the lower support cross beam 62 extends horizontally and is axially telescopic. One end of the lower support cross beam 62 away from the lifting platform 31 has a lower support flange 621, and the three lower support flanges 621 enclose an annular structure;

[0110] The upper support cross beam 61 is hinged to the inner wall of the lifting platform 31, the upper support cross beam 61 is located above the lower support cross beam 62, and along the direction away from the lifting platform 31, the upper support cross beam 61 extends obliquely upward. The upper support cross beam 61 is axially telescopic. One end of the upper support cross beam 61 away from the lifting platform 31 has an upper support flange 611, and the three upper support flanges 611 enclose an annular structure;

[0111] The tower barrel fixing device 6 further includes a driving part 63. The lower end of the driving part 63 is hinged to the lower support cross beam 62, and the upper end of the driving part 63 is hinged to the upper support cross beam 61. The driving part 63 is used to drive the upper support cross beam 61 to rotate around the hinge point in the height direction.

[0112] With the above settings, during the installation process, the three upper support cross beams 61 can be controlled to contract axially first, and the three lower support cross beams 62 can be controlled to contract axially, so that there is enough installation space between the three lower support flanges 621 and between the three upper support flanges 611. Then, the upper tower barrel of the unit is hoisted between the three tower barrel fixing devices 6, the lifting mechanism 3 is moved to a suitable position through the power unit, and then the three lower support cross beams 62 are controlled to extend axially until the three lower support flanges 621 support the lower flange of the tower barrel. Then, the three upper support cross beams 61 are controlled to extend axially, and the driving part 63 is controlled to act, so that the upper support cross beam 61 rotates around the hinge point until the three upper support flanges 611 support the upper flange of the tower barrel, realizing the stable installation of the upper tower barrel of the unit and the tower barrel fixing device 6. Then, the power unit drives the lifting mechanism 3 to rise, and the lifting mechanism 3 can stably drive the tower barrel fixing device 6 and the upper tower barrel of the unit to rise synchronously to adapt to the installation of tower racks at different heights.

[0113] In this embodiment, the upper support cross beam 61 includes a rod part 612 and a sleeve part 613. The sleeve part 613 is connected to the lifting platform 31. The rod part 612 is partially inserted into the sleeve part 613 and is axially movable. One end of the rod part 612 away from the sleeve part 613 is connected to the upper support flange 611;

[0114] The upper support cross beam 61 further includes two telescopic power mechanisms 614. One end of the telescopic power mechanism 614 is connected to the rod portion 612, and the other end is connected to the sleeve portion 613. The two telescopic power mechanisms 614 are located on both sides of the sleeve portion 613. By the action of the telescopic power mechanism 614, the relative movement between the rod portion 612 and the sleeve portion 613 can be achieved, thereby realizing the elongation or shortening of the upper support cross beam 61.

[0115] Among them, the telescopic power mechanism 614 can be a hydraulic cylinder, a pneumatic cylinder or an electric cylinder, etc. The hydraulic cylinder, the pneumatic cylinder or the electric cylinder includes a cylinder body and a push rod. One of the cylinder body and the push rod is connected to the rod portion 612, and the other is connected to the sleeve portion 613. The extension or retraction of the push rod can achieve the relative movement between the rod portion 612 and the sleeve portion 613, which is convenient for controlling the telescopic movement of the upper support cross beam 61.

[0116] In practice, it is also feasible that one end of the rod portion 612 far from the sleeve portion 613 is connected to the lifting platform 31, and the sleeve portion 613 is connected to the upper support flange 611.

[0117] In this embodiment, the upper support cross beam 61 includes two telescopic power mechanisms 614. In practice, the number of telescopic power mechanisms 614 included in the upper support cross beam 61 is not limited. For example, the upper support cross beam 61 can include at least one telescopic power mechanism 614.

[0118] In this embodiment, the telescopic power mechanism 614 is hinged to the sleeve portion 613, the telescopic power mechanism 614 is hinged to the rod portion 612, and the driving portion 63 is hinged to the sleeve portion 613, ensuring reliable transmission and avoiding the situation of being unable to adjust.

[0119] Please refer to Figure 6 , in this embodiment, the lower support cross beam 62 includes an inner rod portion 622 and an outer tube portion 623. The outer tube portion 623 is connected to the lifting platform 31. The inner rod portion 622 is partially inserted inside the outer tube portion 623 and can move axially. One end of the inner rod portion 622 far from the outer tube portion 623 is connected to the lower support flange 621;

[0120] The lower support cross beam 62 further includes a telescopic power mechanism (not shown in the figure). One end of the telescopic power mechanism is connected to the inner rod portion 622, and the other end is connected to the outer tube portion 623. By the action of the telescopic power mechanism, the relative movement between the inner rod portion 622 and the outer tube portion 623 can be achieved, thereby realizing the elongation or shortening of the lower support cross beam 62.

[0121] Among them, the telescopic power mechanism can be a hydraulic cylinder, a pneumatic cylinder or an electric cylinder, etc. The hydraulic cylinder, the pneumatic cylinder or the electric cylinder includes a cylinder body and a push rod. One of the cylinder body and the push rod is connected to the outer tube portion 623, and the other is connected to the inner rod portion 622. The extension or retraction of the push rod can achieve the relative movement between the inner rod portion 622 and the outer tube portion 623, which is convenient for controlling the telescopic movement of the lower support cross beam 62.

[0122] In this embodiment, the telescopic power mechanism is arranged inside the outer tube part 623. In practice, it is also feasible to arrange the telescopic power mechanism outside the outer tube part 623.

[0123] In practice, it is also feasible that one end of the inner rod part 622 is connected to the lifting platform 31, and the end of the outer tube part 623 away from the inner rod part 622 is connected to the lower support flange 621.

[0124] Please refer to Figure 6 and Figure 7 , Figure 7 which is Figure 4 a schematic structural diagram of the lifting mechanism in the installation equipment of the wind turbine generator set.

[0125] In the present utility model, the installation equipment of the wind turbine generator set further includes a lifting mechanism 5. As Figure 6 shown, each connecting beam 32 of the lifting mechanism 3 is provided with a lifting mechanism 5, and a total of six lifting mechanisms 5 are installed on the lifting mechanism 5 to assist in installing the bottom tower of the unit during the installation of the truss tower unit; each lower support cross beam 62 of the tower barrel fixing device 6 is also provided with a lifting mechanism 5, that is, a total of three lifting mechanisms 5 are installed on the tower barrel fixing device 6 to assist in installing the tower barrel of the unit.

[0126] Among them, limiting grooves extending axially are provided on both side walls of the connecting beam 32 and the lower support cross beam 62. The lifting mechanism 5 includes a mounting seat 51, a winch 52 and a driving motor 53 connected to the lower side wall of the mounting seat 51. The mounting seat 51 has two oppositely arranged inverted L-shaped clamping structures 511. A rolling wheel 54 is rotatably installed at the bending part 5111 of the clamping structure 511. In the installed state, the bending part 5111 is clamped inside the limiting groove on the corresponding side part of the connecting beam 32 or the lower support cross beam 62, and the rolling wheel 54 is in rolling fit with the corresponding side wall of the limiting groove. The driving motor 53 is used to drive the rolling wheel 54 and the winch 52 to act. When the driving motor 53 drives the rolling wheel 54 to act, the lifting mechanism 5 moves axially along the connecting beam 32 or the lower support cross beam 62; when the driving motor 53 drives the winch 52 to act, the recovery or release of the lifting rope of the winch 52 is realized.

[0127] During operation, the lifting rope of the winch 52 is connected to the tower barrel or the bottom tower of the unit. The recovery or release of the lifting rope of the winch 52 can realize the rising or falling of the tower barrel or the bottom tower of the unit; the axial movement of the lifting mechanism 5 along the connecting beam 32 or the lower support cross beam 62 can cooperate with the crane to adjust the posture of the tower barrel or the bottom tower of the unit until the tower barrel or the bottom tower of the unit is adjusted to a suitable installation posture.

[0128] In this embodiment, the mounting base 51 further includes a bottom plate 512. The clamping structure 511 is connected to both sides of the bottom plate 512. The bending portion 5111 is located on the upper side of the bottom plate 512, and there is a gap between the bending portion 5111 and the bottom plate 512.

[0129] Wherein, the connection manner between the clamping structure 511 and the bottom plate 512 is not limited. In this embodiment, the clamping structure 511 and the bottom plate 512 are fixedly connected by bolts. In practice, it is also feasible to fixedly connect the clamping structure 511 and the bottom plate 512 by welding.

[0130] Please refer to Figure 8 , Figure 8 For Figure 4 the structural schematic diagram of the base in the installation equipment of the wind turbine generator set.

[0131] In the present utility model, the installation equipment of the wind turbine generator set further includes a base 7. The base 7 is installed at the central position of the triangular structure formed by the entire installation equipment. The base 7 is used to connect the tower barrel to ensure that the wind turbine generator set can stand stably during the installation process.

[0132] Specifically, the base 7 includes a base main body 71 and three legs 72. The three legs 72 are detachably connected to the periphery of the base main body 71. The three legs 72 are circumferentially spaced apart along the base main body 71. The legs 72 play a supporting role for the base main body 71. Different heights of legs 72 can be replaced according to the required height of the base 7 to meet the requirements. For example, when the wind turbine generator set all adopts a steel tower structure, since a concrete structure foundation has been built at the original central position for the final fixation of the wind turbine generator set, therefore, to avoid interference, the base 7 should select higher legs 72 to raise the height of the entire base 7. When the wind turbine adopts a truss tower structure, there is no concrete structure foundation at the original central position. Therefore, lower legs 72 can be selected to reduce the height of the entire base 7.

[0133] Such as Figure 8 shown, a manhole 71a is opened on the circumferential wall of the base main body 71, which is convenient for operators to enter the inside of the base main body 71 from here to install the connecting bolts between the tower barrel and the base main body 71. In practice, external auxiliary equipment such as a ladder can be used for the staff to enter the inside of the base main body 71 from the ground.

[0134] In this embodiment, the number of legs 72 is three. In practice, the number of legs 72 is not limited. For example, the number of legs 72 can also be four or more, as long as the support stability of the base 7 can be ensured.

[0135] Please continue to refer to Figure 8, in this embodiment, the outrigger 72 includes an outrigger main body 721. One end of the outrigger main body 721 away from the base main body 71 is connected with a support base 722. The outrigger main body 721 is supported on the ground through the support base 722. The connection position between the support base 722 and the outrigger main body 721 is adjustable in the height direction to adapt to the poor ground flatness, that is, the influence caused by the height difference of the installation positions of the three outriggers 72, so as to ensure the levelness of the base 7.

[0136] Among them, as Figure 8 shown, one end of the outrigger main body 721 away from the base main body 71 is provided with an open slot 721a with an upper end opening. The open slot 721a penetrates through the corresponding end wall of the outrigger main body 721. A connection hole part is arranged on the bottom wall of the open slot 721a. The support base 722 includes a support base body, an adjustment bolt connected to the upper side of the support base body, and two adjustment nuts sleeved on the adjustment bolt. In the installation state, the adjustment bolt passes through the inside of the connection hole part, and the two adjustment nuts are located on both sides of the bottom wall of the open slot 721a and clamp the bottom wall of the open slot 721a to realize the fixed connection between the outrigger main body 721 and the support base 722; by screwing the two adjustment nuts, the adjustment of the connection position between the support base 722 and the outrigger main body 721 can be realized. It can be seen that this embodiment adopts a mechanical adjustment method, with a simple structure and low cost.

[0137] For the all-steel tower unit, the structure of the installation equipment of the wind turbine generator when installing the all-steel tower unit is as Figure 9 shown. The entire installation process of the wind turbine generator is as follows:

[0138] (1) Install the top section tower barrel 01

[0139] Please combine with Figure 10 understanding. Drive the lifting mechanism 3 to rise to the highest allowable point through the power unit 4, retract the lower support cross beam 62 in the tower barrel fixing device 6, and increase the included angle between the upper support cross beam 61 and the lower support cross beam 62 to reserve enough space for the installation of the top section tower barrel 01 to fall from above. Complete the installation of the top section tower barrel 01 through the cooperation of the three lifting mechanisms 5 installed on the lower support cross beam 62 and the auxiliary crane, and connect the top section tower barrel 01 and the base 7 through bolts. The base 7 plays a stable supporting role.

[0140] (2) Install the nacelle 02

[0141] Please combine with Figure 11 understanding. Drive the lifting mechanism 3 to descend through the power unit 4 to reserve enough installation space for the installation of the nacelle 02 and the subsequent hub, that is, there is no interference between the upper support cross beam 61 in the tower barrel fixing device 6 and the nacelle 02 and the hub. Complete the installation of the nacelle 02 through an external crane.

[0142] (3) Install the hub 03

[0143] Please understand in combination with Figure 12 Since the installation equipment is inoperative, the hoisting of the hub 03 is completed by an external crane.

[0144] (4) Installation of the bottom section tower barrel 04 and other section tower barrels

[0145] The power unit 4 drives the lifting mechanism 3 to descend, so that the lower support flange 621 of the lower support cross beam 62 in the tower barrel fixing device 6 is flush with the lower flange of the top section tower barrel 01;

[0146] The three lower support cross beams 62 extend, and the arc-shaped structure of the lower support flange 621 coincides with the arc of the lower flange of the top section tower barrel 01, and the openings on the arc-shaped structure coincide with the openings of the lower flange of the top section tower barrel 01;

[0147] The three upper support cross beams 61 extend, and the driving part 63 correspondingly adjusts the angle between the upper support cross beam 61 and the lower support cross beam 62, so that the upper support flange 611 of the upper support cross beam 61 coincides with the upper flange of the top section tower barrel 01, and the positioning pins on the upper support flange 611 are inserted into the openings of the upper flange of the top section tower barrel 01.

[0148] Through the above operations, the fixation of the upper support cross beam 61 and the lower support cross beam 62 in the tower barrel fixing device 6 with the top section tower barrel 01 is completed.

[0149] Then, the power unit 4 drives the lifting mechanism 3 to move upward, and the movement of the lifting mechanism 3 drives the tower barrel fixing device 6 to move upward, so as to complete driving the completed part of the wind turbine generator set to move upward as a whole, and the moving height needs to meet the installation of the next section of the tower barrel.

[0150] Then, through the cooperation of the three lifting mechanisms 5 installed on the lower support cross beam 62 and the auxiliary crane, the installation of the lower section or the bottom section tower barrel 04 is completed, and the lower section or the bottom section tower barrel 04 is installed on the base 7 and effectively fixed.

[0151] Immediately afterwards, the power unit 4 drives the lifting mechanism 3 to move downward, and the movement of the lifting mechanism 3 drives the tower barrel fixing device 6 to move downward, so as to drive the completed part of the wind turbine generator set to move downward as a whole until the lower flange of the top section tower barrel 01 coincides with the upper flange of the lower section or the bottom section tower barrel 04 fixed on the base 7, and bolts are used for effective fixation, as Figure 13 shown.

[0152] Immediately afterwards, the connecting bolts between the lower section or the bottom section tower barrel 04 and the base 7 are removed, and the power unit 4 drives the lifting mechanism 3 to move upward, and the movement of the lifting mechanism 3 drives the tower barrel fixing device 6 to move upward, so as to drive the completed part of the wind turbine generator set to move upward as a whole, and the removal of the base 7 is completed by other cranes.

[0153] Finally, the power unit 4 drives the lifting mechanism 3 to move downward. The movement of the lifting mechanism 3 drives the tower barrel fixing device 6 to move downward, which can drive the completed part of the wind turbine generator set to move downward as a whole, making the bottom tower barrel 04 coincide with the wind turbine foundation, and effectively fixing it with bolts. Then the installation of other components except the blades can be completed. Remove the installation equipment, and complete the installation of the blades by crane, thus completing the installation of the entire all-steel tower wind turbine generator set.

[0154] For the truss tower unit, the entire installation process of the wind turbine generator set is as follows:

[0155] (1) Install the top tower barrel 01

[0156] This process is the same as that of the all-steel tower unit and will not be elaborated here.

[0157] (2) Install the nacelle 02

[0158] This process is the same as that of the all-steel tower unit and will not be elaborated here.

[0159] (3) Install the hub 03

[0160] This process is the same as that of the all-steel tower unit and will not be elaborated here.

[0161] (4) Installation of the truss tower, which includes the transition stage tower barrel 051 and at least one section of the bottom tower frame 052.

[0162] First, the power unit 4 drives the lifting mechanism 3 to descend, making the lower support flange 621 of the lower support crossbeam 62 in the tower barrel fixing device 6 flush with the lower flange of the top tower barrel 01. The three lower support crossbeams 62 extend, and the arc-shaped structure of the lower support flange 621 coincides with the arc of the lower flange of the transition stage tower barrel 051. The openings on the arc-shaped structure coincide with the openings of the lower flange of the top tower barrel 01. The three upper support crossbeams 61 extend, and the angle between the upper support crossbeam 61 and the lower support crossbeam 62 is adjusted accordingly through the driving part, making the upper support flange 611 of the upper support crossbeam 61 coincide with the upper flange of the top tower barrel 01, and inserting the positioning pin on the upper support flange 611 into the opening inside the upper flange of the top tower barrel 01. Through the above operations, the fixing of the upper support crossbeam 61 and the lower support crossbeam 62 in the tower barrel fixing device 6 with the top tower barrel 01 is completed.

[0163] Secondly, the power unit 4 drives the lifting mechanism 3 to move upward. The movement of the lifting mechanism 3 drives the tower barrel fixing device 6 to move upward, which can complete driving the completed part of the wind turbine generator set to move upward as a whole. The moving height needs to meet the installation of the next section of the tower barrel.

[0164] Next, with the cooperation of the three lifting mechanisms 5 installed on the lower support cross beam 62 and the auxiliary crane, the installation of the transition stage tower barrel 051 is completed. The transition stage tower barrel 051 is installed on the base 7 and effectively fixed. As Figure 14 shown.

[0165] Then, the power unit 4 drives the lifting mechanism 3 to move downward. By the movement of the lifting mechanism 3, the tower barrel fixing device 6 is driven to move downward, and then the completed part of the wind turbine generator set can be driven to move downward as a whole until the lower flange of the top tower barrel 01 coincides with the upper flange of the transition stage tower barrel 051 fixed on the base 7, and bolts are used for effective fixation. As Figure 15 shown.

[0166] Then, the tower barrel fixing device 6 and the auxiliary equipment installed on the tower barrel fixing device 6 are removed. As Figure 16 shown.

[0167] Then, the power unit 4 drives the lifting mechanism 3 to move downward, so that the three columns of the transition stage tower barrel 051 are respectively located between the corresponding two connecting beams 32. Through the action of the external crane, the installation of the transition stage tower barrel 051 and the fixing device 1 is completed.

[0168] Immediately afterwards, the power unit 4 drives the lifting mechanism 3 to move upward, and drives the installed part of the wind turbine generator set to move upward as a whole, leaving a space for the removal of the base 7, and the removal of the base 7 is completed. As Figure 17 shown.

[0169] Immediately afterwards, through the action of the lifting mechanisms 5 installed on the two connecting beams 32 connected to the same lifting platform 31, the installation of the columns of one bottom tower frame 052 is completed. Through the combined action of three groups of six lifting mechanisms 5 in total, the installation of the columns of the three bottom tower frames 052 is completed.

[0170] Immediately afterwards, the power unit 4 drives the lifting mechanism 3 to move downward, and drives the installed part of the wind turbine generator set to move as a whole for adaptive adjustment, so that the columns of the bottom tower frame 052 are in effective contact with the ground foundation and fixed.

[0171] Then, through the combined action of the small hoists installed on the connecting beams 32, the installation of the support cross beams between the columns of the bottom tower frame 052 is completed. As Figure 18 shown.

[0172] Finally, through the action of the external crane, the installation equipment of the entire wind turbine generator set is removed, and then through the crane, the installation of the three blades is completed, and the installation of the entire truss tower unit can be completed.

[0173] It can be understood that the installation process of each bottom tower 052 is the same. Therefore, only the installation of one bottom tower 052 will be described in detail here, and the other segments will be configured according to the actual height requirements of the project, and no repeated description will be made here.
