Description

Technical Field

[0001] The present invention relates to the technical field of marine engineering equipment, and in particular to a modular clamping structure of a fan blade installation device and an installation method thereof. Background Art

[0002] Offshore wind turbines are devices that convert ocean wind energy into electrical energy, and are usually composed of wind turbine blades, a nacelle, a tower, and a foundation. During the assembly of offshore wind turbines, large clamping equipment is usually used to clamp the two sides of the wind blades and assemble them onto the hub of the tower. Since the offshore construction environment is relatively complex, there are also high requirements for the quality, accuracy, and ease of use of wind turbine blade installation equipment.

[0003] There are various existing wind blade installation devices. For example, the Chinese invention patent with publication number CN115215192A and patent name “Method for self-adjusting storage and hoisting of wind turbine blades” discloses an inter-blade working condition adaptive integrated device, including an inter-blade base and a lower half and an upper half of a rotating drum rotatably mounted on the inter-blade base. The upper half of the rotating drum is buckled and connected with the lower half of the rotating drum, and gear teeth are continuously provided with each other. The gear teeth cooperate with a gear set installed on one side of the inter-blade base, and the gears also cooperate with racks installed on the lifting plate and the inter-blade lifting ears; a rear contour plate is provided on one side of the inter-blade base, a front lower contour plate is provided on the lower half of the rotating drum, and a front upper contour plate is provided on the upper half of the rotating drum, and the front upper contour plate is arranged opposite to the front lower contour plate;

[0004] The assembled blades are in a storage state lying flat on the rear contour plate, the front lower contour plate and the front upper contour plate; when hoisting, it is only necessary to hang the sling on the inter-blade lifting ears. During the lifting process, the lifting plate rises, the rack drives the gear to rotate, and the gear drives the lower half and the upper half of the rotating drum to rotate, so that the blades are adjusted from a horizontal state to a sideways state without any external intervention; when the blades are installed in place and firmly connected to the hub, the crane loosens the hook slightly, and the inter-blade working condition adaptive integrated device moves slightly downward by a certain distance, that is, it is separated from the blade, and then the device moves along the long axis of the blade and finally separates from the blade, completing the transition from storage (transportation) state to hoisting and then to separation, which is completely automatic and does not require any unnecessary external intervention.

[0005] However, the prior art still has the following defects:

[0006] 1. The existing wind turbine blade installation equipment uses an integrated device for adaptive working conditions between blades, the purpose of which is to solve the transportation, storage and lifting of blades through a set of devices; however, this integrated installation equipment has a relatively large overall weight and size, and requires a relatively large lifting equipment with a high lifting capacity to complete the lifting work, so the lifting cost is relatively high;

[0007] 2. The existing integrated installation equipment cannot be assembled in a modular manner. A large number of bolts and screws are required during the assembly process, especially when installing the lower half of the drum and the upper half of the drum. The lower half of the drum and the upper half of the drum need to be relatively accurately matched, and the gear set and rack are assembled. The assembly process is numerous and the assembly precision requirements are high and complex;

[0008] 2. In addition, the various structural components of the existing integrated installation equipment cannot be produced in a standardized manner, resulting in higher production costs. Summary of the invention

[0015] Furthermore, a first mounting groove is provided on the assembly surface of the shell base, and a plurality of locking shafts are provided in the first mounting groove. When the clamping base is assembled on the shell base, the locking arm of the first locking assembly extends into the first mounting groove and locks the locking shaft through the locking end.

[0022] In order to overcome the deficiencies of the prior art, a second object of the present invention is to provide a modular clamping structure installation method for a wind turbine blade installation device.

[0023] The second object of the present invention is achieved by adopting the following technical solution: a modular clamping structure installation method of a fan blade installation device, comprising the following installation steps:

[0024] S1. Place the housing base in advance, then install the clamping base on the assembly surface of the housing base and lock it through a locking mechanism;

[0025] S2, pre-install the gripper assembly on the clamping surfaces of the two clamping side seats, and install the locking mechanism on the locking surfaces of the two clamping side seats; then first install one clamping side seat and the gripper assembly on its clamping surface on the left end / right end of the clamping base in step S1; then install the other clamping side seat and the gripper assembly on its clamping surface on the other end of the clamping base, and arrange the gripper assemblies on the two clamping side seats facing each other;

[0026] S3. Install the two shell side seats on the left and right ends of the shell base in step S1 in sequence, and lock the assembly surface of the shell side seat through the locking mechanism on the locking surface of the clamping side seat in step S2, so that the modular assembly is completed in sequence among the shell base, the clamping base, the clamping side seat and the shell side seat.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] (1) In the embodiment of the present application, the outer shell base assembly and the clamping base assembly are arranged in multiple sections. When assembling the clamping structure, it is only necessary to pre-assemble the clamping base on the outer shell base, assemble the clamping hand assembly on the clamping side seat, and then sequentially splice the clamping side seats at the left and right ends of the clamping base and the left and right ends of the outer shell base, so that the clamping structure can be modularly assembled;

[0029] Compared with the installation equipment that has adopted the integrated device for adaptively adjusting the inter-blade working condition in the past, the embodiment of the present application adopts a modular clamping structure with modular assembly, which only needs to use miniaturized lifting equipment for lifting and assembly, and the lifting cost is relatively low; the outer shell seat assembly, the clamping seat assembly and the clamping hand assembly can be mutually buckled and locked through a locking mechanism during modular assembly, and each component is modularly arranged, without the need to use a large number of bolts and screws, with low assembly accuracy requirements and simple assembly procedures, thereby achieving the purpose of quick installation; the outer shell seat assembly, the clamping seat assembly and the clamping hand assembly of the modular clamping structure can all be manufactured and produced in a standardized manner, reducing the manufacturing cost.

[0030] (2) The left and right ends of the shell base are provided with a first plug-in component. When the shell base is assembled with the shell side seat, the cover panel of the first plug-in component is matched with the notch portion of the shell side seat so that the surface of the cover panel and the assembly surface of the shell side seat are on the same plane, thereby improving the aesthetics of the assembly between the shell base and the shell side seat; and a plurality of limiting convex strips on the inner side of the cover panel are embedded in the plug hole of the notch portion, thereby further improving the assembly stability, thereby realizing convenient modular assembly of the shell side seat and the shell base, and the assembly is time-saving and labor-saving.

[0031] (3) The left and right ends of the clamping base are provided with second plug-in components, which are used to plug into the plug-in holes on the splicing ends of the clamping side seats when the left and right ends of the clamping base are spliced ​​and assembled. Therefore, when modularly assembling the clamping seat assembly, it is only necessary to align the plug-in holes of the clamping side seats with the second plug-in components on the clamping base, and insert the second plug-in components into the plug-in holes to complete the convenient modular assembly of the clamping side seats and the clamping base, which saves time and effort.

[0032] (4) By setting a first locking component on the locking surface of the clamping base, when the clamping base is spliced ​​and assembled on the shell base, the locking arm extends into the first installation groove, and the first clamping driver controls the first clamping block to be embedded in the clamping end of the locking arm, so that the locking arm of the locking arm is opened and clamped into the locking shaft in the first installation groove; then, the first clamping driver controls the first clamping block to withdraw from the clamping end of the locking arm, and under the elastic action of the torsion spring, the locking ends of the two locking sub-arms of the locking arm will tighten and lock the locking shaft in the first installation groove towards each other, thereby completing the modular assembly and automatic locking of the clamping base and the shell base, eliminating the previous assembly method of using a large number of bolts and screws, reducing assembly costs and improving assembly efficiency.

[0033] (5) By setting a second locking assembly on the locking surface of the clamping side seat, when the shell side seat is spliced ​​and assembled on the shell base and the clamping side seat, the second clamping block is controlled by the second clamping driver to push the back sides of the two hook arms, so that the locking hooks of the two hook arms are locked with the shell side seat; eliminating the previous assembly method of using a large number of bolts and screws, and realizing modular rapid splicing and assembly of the shell side seat and the clamping side seat, thereby reducing assembly costs and improving assembly efficiency. When unlocking, it is only necessary to control the second clamping block to retreat from the back sides of the two hook arms through the second clamping driver, so that the two hook arms can release the shell side seat, thereby unlocking the locking state of the shell side seat and the clamping side seat, and the operation is simple and convenient.

[0034] (6) A modular assembly method is adopted in which the clamping base is first spliced ​​onto the shell base, the clamping side seats are then spliced ​​onto the left and right ends of the clamping base, and finally the shell side seats are spliced ​​together. This can avoid the problem of collision and interference between the shell side seats and the clamping side seats when the shell side seats are first assembled and then the clamping side seats are assembled.

[0035] In addition, by first assembling the clamping hand assembly on the locking surface of the clamping side seat and then splicing and assembling them together on the left and right ends of the clamping base, it is also possible to avoid the problem of collision and interference between the two clamping side seats and the assembly of the clamping hand assembly when the clamping side seat is assembled first and then the clamping hand assembly. Therefore, through the above optimization of the modular assembly steps of the clamping structure, the assembly efficiency of the clamping structure is greatly improved, and the risk of assembly safety accidents is reduced. In addition, the locking mechanism is used to automatically lock each component during the assembly process, which greatly reduces a lot of assembly costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0045] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0046] like Figure 1-7 As shown, a modular clamping structure of a fan blade installation device includes an outer shell seat assembly 1, a clamping seat assembly 2 and a clamping hand assembly 3. After the outer shell seat assembly 1 is assembled, its outer shape is roughly a semicircular structure. The clamping seat assembly 2 is assembled on the semicircular inner side of the outer shell seat assembly 1, and the clamping hand assembly 3 is assembled on the clamping seat assembly 2. The clamping hand assembly 3 performs opposite movements on the clamping seat assembly 2 to clamp the two sides of the fan blade.

[0047] More specifically, the outer shell seat assembly 1 has an outer shell base 10 and an outer shell side seat 11. The outer side surfaces of the outer shell base 10 and the outer shell side seat 11 are both arc-shaped and provided with teeth. The outer shell base 10 and the outer shell side seat 11 can cooperate with the gear set of the bottom frame through the teeth on their outer side surfaces. Under the transmission action of the gear set on the outer side surface of the outer shell seat assembly 1, the entire modular clamping structure can be rotated on the bottom frame, so as to adjust the angle of the fan blades on the modular clamping structure, so as to facilitate the lifting of the fan blades.

[0048] like Figure 6-7 As shown, the inner side surfaces of the shell base 10 and the shell side seat 11 are both assembly surfaces 12. A first mounting groove 102 and a plurality of limit grooves 111 are provided on the assembly surface 12 of the shell base 10. A plurality of locking shafts 103 arranged in parallel and at intervals are provided in the first mounting groove 102.

[0049] The left and right ends of the shell base 10 are each provided with a first connector 101 extending obliquely upward. The first connector 101 has a cover panel 1010 and a plurality of limiting convex strips 1011 arranged on the inner side of the cover panel 1010. The surface of the cover panel 1010 is connected to the assembly surface 12 of the shell base 10.

[0050] One end where the shell side seat 11 and the shell base 10 are spliced ​​is provided with a notch portion 110 and a plurality of limiting grooves 111 arranged on the notch portion 110. The notch portion 110 is opened on the assembly surface 12 of the shell side seat 11. The notch portion 110 extends from the splicing end of the shell side seat 11 to the middle part, and one end of the limiting groove 111 is also reserved on the splicing end of the shell side seat 11.

[0051] Therefore, when assembling the outer shell seat assembly 1, the outer shell side seat 11 is installed at both the left and right ends of the outer shell base 10, and the outer shell side seat 11 can be installed at the left or right end of the outer shell base 10 first. The notch 110 of the outer shell side seat 11 is matched with the cover panel 1010 of the outer shell base 10, and the limiting convex strip 1011 is embedded in the limiting groove 111. A plurality of plug rods are also provided on the inner side of the cover panel 1010 for plugging the plug hole on the notch 110, which can further improve the assembly stability, thereby realizing the convenient modular assembly of the outer shell side seat 11 and the outer shell base 10, and the assembly is time-saving and labor-saving. After the cover panel 1010 is matched with the notch 110, the surface of the cover panel 1010 and the assembly surface 12 of the outer shell side seat 11 are on the same plane, which improves the assembly aesthetics between the outer shell base 10 and the outer shell side seat 11.

[0052] The clamping seat assembly 2 comprises a clamping base 20 and a clamping side seat 21 . The outer side surfaces of the clamping base 20 and the clamping side seat 21 are locking surfaces 22 and are respectively provided with locking mechanisms 4 . The inner side surfaces of the two clamping side seats 21 are clamping surfaces 23 .

[0053] The left and right ends of the clamping base 20 are respectively provided with second plug-in components 201 extending obliquely upwards. The second plug-in components 201 are plug-in blocks. Two plug-in blocks are respectively provided at the left and right ends of the clamping base 20. A plug-in hole 210 is provided at one end where the clamping side seat 21 is spliced ​​with the clamping base 20.

[0054] Therefore, when assembling the clamping seat assembly 2, the clamping side seats 21 are installed on both ends of the clamping base 20. You can choose to install the clamping side seat 21 on the left or right end of the clamping base 20 first. You only need to align the plug-in hole 210 of the clamping side seat 21 with the second connector 201 on the clamping base 20, and insert the second connector 201 into the plug-in hole 210 to complete the convenient modular assembly of the clamping side seat 21 and the clamping base 20, which saves time and effort.

[0055] In the daily assembly process, the assembly order of the modular clamping structure is to first install the clamping base 20 on the shell base 10, then install the clamping side seat 21 with the pre-installed clamping hand assembly 3 on the left and right ends of the clamping base 20, and finally install the shell side seat 11 on the left and right ends of the shell base 10. This installation method is the preferred installation method, which can better avoid the collision and interference between the shell side seat 11 and the clamping side seat 21, the collision and interference between the clamping base 20 and the shell side seat 11, and the collision and interference between the clamping hand assembly 3 and the clamping side seat 21, thereby improving the assembly smoothness and assembly efficiency of the modular clamping structure.

[0056] According to the assembly sequence of the above modular clamping structure, when the clamping base 20 is installed on the outer shell base 10, in addition to the locking mechanism 4, the locking surface 22 of the clamping base 20 is also provided with a limit block. When the clamping base 20 is installed on the outer shell base 10, the limit block can be embedded in the limit groove 111 of the assembly surface 12 of the outer shell base 10, which can further improve the assembly stability and assembly accuracy.

[0057] like Figure 3 , 4 As shown, in the embodiment of the present application, the locking mechanism 4 provided on the locking surface 22 of the clamping base 20 adopts a first locking assembly 40, so when the clamping base 20 is installed on the assembly surface 12 of the outer shell base 10, the outer shell base 10 is also locked by the first locking assembly 40.

[0058] More specifically, the first locking assembly 40 has a locking arm 401, a first clamping block 402 and a first clamping driver 403. The locking arm 401 is elastically mounted on the locking surface 22 of the clamping base 20 through a torsion spring. One end of the locking arm 401 is a locking end 4010, and the other end of the locking arm 401 is a normally elastically tightened clamping end 4011, on which a slide 40110 is provided.

[0059] Each locking arm 401 is composed of two locking sub-arms arranged opposite to each other, so under the elastic action of the torsion spring, the clamping ends 4011 of the two locking sub-arms will remain in an elastically tightened state facing each other, and the other locking ends 4010 will remain in a reverse expanded state.

[0060] The first clamping driver 403 is installed in the clamping base 20, and the first clamping block 402 is roughly in a trapezoidal structure. The larger end of the first clamping block 402 is connected to the output end of the first clamping driver 403 through a connecting rod, and a tension spring is sleeved on the connecting rod. Therefore, under the control of the first clamping driver 403, the first clamping block 402 can move toward the locking arm 401, so that the smaller end of the first clamping block 402 is embedded between the clamping ends 4011 of the two locking sub-arms, and the slide 40110 on the clamping end 4011 and the inclined side of the first clamping block 402 slide against each other.

[0061] When the first clamping driver 403 controls the first clamping block 402 to gradually embed into the clamping ends 4011 of the two locking sub-arms, the clamping ends 4011 of the two locking sub-arms will gradually open, so that the locking ends 4010 of the two locking sub-arms are gradually locked toward each other; when the first clamping driver 403 controls the first clamping block 402 to gradually withdraw from the clamping ends 4011 of the two locking sub-arms, and under the elastic tension of the tension spring, the clamping ends 4011 of the two locking sub-arms will gradually tighten toward each other along the inclined surface of the first clamping block 402, so that the locking ends 4010 of the two locking sub-arms are gradually opened in the opposite direction.

[0062] Therefore, according to the action principle of the above-mentioned first locking component 40 and the structural design of the shell base 10, when the clamping base 20 is assembled on the assembly surface 12 of the shell base 10, the locking arm 401 extends into the first installation groove 102, and the first clamping driver 403 controls the first clamping block 402 to be embedded in the clamping end 4011 of the locking arm 401, so that the locking arm 401 of the locking arm 401 is opened and clamped into the locking shaft 103 in the first installation groove 102; then, the first clamping driver 403 controls the first clamping block 402 to withdraw from the clamping end 4011 of the locking arm 401, and under the elastic action of the torsion spring, the locking ends 4010 of the two locking sub-arms of the locking arm 401 will tighten and lock the locking shaft 103 in the first installation groove 102 towards each other, thereby completing the modular assembly and automatic locking work of the clamping base 20 and the shell base 10, eliminating the previous assembly method of using a large number of bolts and screws, reducing assembly costs and improving assembly efficiency.

[0063] like Figure 3 , 5 As shown, after the clamping side seats 21 at the left and right ends of the clamping base 20 are installed, the next step of assembling the outer shell side seat 11 is carried out. In the embodiment of the present application, the locking mechanism 4 arranged on the locking surface 22 of the clamping side seat 21 adopts a second locking component 41. Therefore, when the splicing end of the outer shell side seat 11 is spliced ​​with the left and right ends of the outer shell base 10, the assembly surface 12 of the outer shell side seat 11 is also locked by the second locking component 41 on the clamping side seat 21.

[0064] More specifically, a second mounting groove 112 is provided on the assembly surface 12 of the housing side seat 11 , and a groove wall of the second mounting groove 112 is provided with hooking portions 1120 that are recessed toward both sides.

[0065] The second locking assembly 41 has a hook arm 410, a second clamping block 412 and a second clamping driver 413. Two hook arms 410 are provided. One end of the two hook arms 410 is movably connected in the second mounting groove 112 of the shell side seat 11, and the two hook arms 410 are arranged back to back to each other. The other end of the hook arm 410 is provided with a locking hook 4101, so the locking hooks 4101 of the two locking arms are respectively arranged in the direction of the hooking parts 1120 on both sides of the second mounting groove 112, so that the hook arm 410 can swing in the second mounting groove 112 and hook the locking hook 4101 to the hooking part 1120.

[0066] The second clamping driver 413 is installed in the clamping side seat 21. The second clamping block 412 is the same as the first clamping block 402, and both are set as a trapezoidal structure, so the larger end of the second clamping block 412 is connected to the output end of the second clamping driver 413 through a connecting rod, and a tension spring can also be optionally sleeved on the connecting rod. The locking surface 22 of the clamping side seat 21 is provided with a U-shaped locking buckle 414 extending outward, and the locking hook 4101 of the hook arm 410 needs to be hooked on the locking buckle 414 when the locking action is performed.

[0067] Therefore, under the control of the second clamping driver 413 , the second clamping block 412 can move toward the direction of the two back-to-back locking arms, so that the smaller end of the second clamping block 412 is embedded between the back sides of the two hook arms 410 .

[0068] When the second clamping driver 413 controls the second clamping block 412 to gradually move toward the two hook arms 410, and the second clamping block 412 pushes the back sides of the two hook arms 410, the locking hooks 4101 of the two hook arms 410 swing toward the hooking parts 1120 of the second mounting groove 112 respectively, and as the second clamping block 412 continues to push, the locking hooks 4101 of the hook arms 410 are hooked onto the hooking parts 1120 of the second mounting groove 112.

[0069] During the hooking action of the hook arm 410, since the locking buckle 414 on the clamping side seat 21 also extends into the second installation groove 112, the hook arm 410 is also hooked on the locking buckle 414 through the locking hook 4101, and continues to be hooked to the hooking portion 1120 of the second installation groove 112. Due to the hooking action of the hook arm 410 on the locking buckle 414, the locking buckle 414 generates a pulling force on the clamping side seat 21 in the direction of the shell side seat 11, and the shell side seat 11 is also pressed and spliced ​​in the direction of the clamping side seat 21. Similarly, the previous assembly method using a large number of bolts and screws is eliminated, and the modular quick splicing assembly of the shell side seat 11 and the clamping side seat 21 is realized, reducing assembly costs and improving assembly efficiency.

[0070] When the second clamping driver 413 controls the second clamping block 412 to gradually withdraw from the back sides of the two hook arms 410, the two hook arms 410 will loosen the hooking portion 1120 and the locking buckle 414 of the second mounting groove 112, thereby unlocking the locking state of the shell side seat 11 and the clamping side seat 21. The operation is simple and convenient.

[0071] In the embodiment of the present application, the locking action of the clamping base 20 and the shell base 10 can adopt the first locking assembly 40 or the second locking assembly 41. Similarly, the locking action of the clamping side seat 21 and the shell side seat 11 can adopt the first locking assembly 40 or the second locking assembly 41. In addition, the first clamping driver 403 and the second clamping driver 413 used can be selected from one of a ratchet assembly, a pneumatic driver and a linear motor. Among them, the second clamping driver 413 preferably adopts a pneumatic driver to control the pushing action of the second clamping block 412. At this time, it is necessary to set an air cavity in the clamping side seat 21, and an air duct connecting the air cavity with the pneumatic driver, so that the airflow of the air cavity provides air source power to the pneumatic driver through the air duct.

[0072] In order to further improve the fastness of the splicing assembly between the housing side seat 11 and the clamping side seat 21, a slot member 5 is installed between the clamping side seat 21 and the housing side seat 11, and the slot member 5 has an assembly groove 50 and a positioning seat 51. When the slot member 5 is assembled with the clamping side seat 21, the slot member 5 is clamped on the end of the clamping side seat 21 away from the clamping base 20 through its assembly groove 50, and a limiting block is arranged in the groove wall of the assembly groove 50, and limiting grooves 111 adapted to the limiting blocks are opened on the locking surface 22 and both sides of the clamping side seat 21, so as to improve the assembly stability between the slot member 5 and the clamping side seat 21.

[0073] In addition, the positioning seat 51 on the outer side of the slot member 5 is used to assemble with the shell side seat 11, so when the shell side seat 11 is spliced ​​on the left and right ends of the shell base 10 and the locking surface 22 of the clamping side seat 21, the assembly surface 12 of the shell side seat 11 away from the end of the shell base 10 is clamped on the positioning seat 51 of the sub-slot member 5, and the positioning seat 51 has two limiting plates for limiting and clamping the two side surfaces of the shell side seat 11, so that the ends of the clamping side seat 21 and the shell side seat 11 are further buckled and assembled through the slot member 5, so that the shell side seat 11 is more firmly modularly assembled on the clamping side seat 21.

[0074] like Figure 1-3 As shown, the assembly work of the clamping hand assembly 3 and the clamping surface 23 of the clamping side seat 21 is further described. Specifically, the clamping hand assembly 3 has a first clamping hand 30 and a second clamping hand 31. The first clamping hand 30 and the second clamping hand 31 are respectively and correspondingly installed on the locking surfaces 22 of the clamping side seat 21 at the left and right ends of the clamping base 20. Therefore, when in use, the first clamping hand 30 and the second clamping hand 31 move towards each other to clamp both sides of the fan blade.

[0075] The first gripper 30 and the second gripper 31 of the embodiment of the present application are respectively provided with a clamping driver 32, a clamping arm 33, a clamping plate 34 and a crank connecting rod 35. The clamping driver 32 used can be a cylinder or a linear motor. When installing the gripper assembly 3, the clamping arm 33 is provided with two sections, one end of the two sections of the clamping arm 33 is hinged to each other, and the other end is respectively provided with a clamping plate 34. The two sections of the clamping arm 33 are respectively connected to one end of the clamping driver 32, and the other end of the clamping driver 32 is connected to the clamping surface 23 of the clamping side seat 21, so the clamping arm 33 can be driven by the clamping driver 32 to perform a swing-type clamping action with the hinged end as the fulcrum.

[0076] The crank connecting rod 35 is composed of a support rod 350 and a push rod 351. One end of the support rod 350 is movably connected to the clamping arm 33, and the other end is movably connected to the clamping surface 23 of the clamping side seat 21, so that the clamping arm 33 is supported by the support rod 350. One end of the push rod 351 is connected to the middle part of the support rod 350, and the other end is connected to the push chute 211 on the clamping surface 23 of the clamping side seat 21. The push chute 211 is provided with a sliding roller, so that one end of the push rod 351 can slide back and forth on the sliding roller of the push chute 211.

[0077] Therefore, when the pushing rod 351 slides on the pushing slide groove 211, it drives the support rod 350 to swing, and drives the clamping arm 33 through the support rod 350, so that the clamping arm 33 pushes the fan blades outward under the interlocking action of the crank connecting rod 35, so as to facilitate the lifting of the fan blades and avoid collision interference caused by the clamping side seat 21 in the lifting of the fan blades.

[0078] In this way, the embodiment of the present application sets the outer shell base assembly 1 and the clamping base assembly 2 in multiple sections. When assembling the clamping structure, it is only necessary to pre-assemble the clamping base 20 on the outer shell base 10, assemble the clamping hand assembly 3 on the clamping side seat 21, and then sequentially splice the clamping side seats 21 at the left and right ends of the clamping base 20 and the left and right ends of the outer shell base 10, so that the clamping structure can be modularly assembled;

[0079] Compared with the installation equipment that has adopted the integrated device for adaptively adjusting the inter-blade working condition in the past, the embodiment of the present application adopts a modular clamping structure with modular assembly, which only needs to use miniaturized lifting equipment for lifting and assembly, and the lifting cost is relatively low; the outer shell seat assembly 1, the clamping seat assembly 2 and the clamping hand assembly 3 can be mutually locked by the locking mechanism 4 during modular assembly, and each component is modularly arranged, without the need to use a large number of bolts and screws, with low assembly accuracy requirements and simple assembly procedures, thereby achieving the purpose of quick installation; the outer shell seat assembly 1, the clamping seat assembly 2 and the clamping hand assembly 3 of the modular clamping structure can all be manufactured and produced in a standardized manner, thereby reducing the manufacturing cost.

[0080] In the embodiment of the present application, the modular clamping structure installation method of the fan blade installation equipment mainly includes the following installation steps:

[0081] S1, pre-place the housing base 10, then install the clamping base 20 on the assembly surface 12 of the housing base 10 and lock it through the locking mechanism 4;

[0082] S2, pre-install the gripper assembly 3 on the clamping surfaces of the two clamping side seats 21, and install the locking mechanism 4 on the locking surfaces 22 of the two clamping side seats 21; then first install one clamping side seat 21 and the gripper assembly 3 on its clamping surface on the left end / right end of the clamping base 20 in step S1; then install the other clamping side seat 21 and the gripper assembly 3 on its clamping surface on the other end of the clamping base 20, and arrange the gripper assemblies 3 on the two clamping side seats 21 facing each other;

[0083] S3. Install the two shell side seats 11 on the left and right ends of the shell base 10 in step S1 in sequence, and lock the assembly surface 12 of the shell side seat 11 through the locking mechanism 4 on the locking surface 22 of the clamping side seat 21 in step S2, so that the modular assembly is completed in sequence between the shell base 10, the clamping base 20, the clamping side seat 21 and the shell side seat 11.

[0084] In this way, by first splicing the clamping base 20 onto the shell base 10, then splicing the clamping side seats 21 at the left and right ends of the clamping base 20, and finally splicing and assembling the shell side seats 11 in a modular assembly manner, it is possible to avoid the problem of collision and interference between the shell side seats 11 and the clamping side seats 21 when the shell side seats 11 are first assembled and then the clamping side seats 21 are assembled;

[0085] In addition, the clamping hand assembly 3 is first assembled on the locking surface 22 of the clamping side seat 21, and then assembled together on the left and right ends of the clamping base 20. This can also avoid the problem of collision interference between the two clamping side seats 21 and the assembly of the clamping hand assembly 3 when the clamping side seat 21 is assembled first and then the clamping hand assembly 3. Therefore, through the above optimization of the modular assembly steps of the clamping structure, the assembly efficiency of the clamping structure is greatly improved, and the risk of assembly safety accidents is reduced. In addition, the locking mechanism 4 is used to automatically lock each component during the assembly process, which greatly reduces a lot of assembly costs.

[0086] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
