[0048] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0051] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0052] See also Figure 1-Figure 7 An embodiment of the present application provides a wind power gearbox fixing device, including a fixing seat 1, a supporting platform 2, an adjustment component 3, a moving seat 5, a positioning component 9 and a suppression component 6.

[0053] like Figure 1 As shown, a movable seat 5 is slidably connected to one side of the fixed seat 1 in the length direction, a support platform 2 is arranged on the other side of the fixed seat 1 in the length direction, and a positioning assembly 9 is arranged on the side of the support platform 2 away from the fixed seat 1 and the other side of the movable seat 5, see Figure 1-Figure 4 An adjusting component 3 for adjusting the horizontal spacing of the movable seat 5 relative to the fixed seat 1 is arranged inside the fixed seat 1, and a rotating column 11 is arranged on the side wall of the fixed seat 1. The rotating column 11 is connected to the adjusting component 3 and can control the adjusting component 3 to push and pull the movable seat 5 horizontally when rotating. The side wall of the fixed seat 1 is also provided with a restraining component 6 located next to the rotating column 11 and capable of limiting the rotation of the rotating column 11.

[0054] The wind power gearbox fixing device provided in the embodiment of the present application has a movable seat 5 slidably connected to one side of the fixed seat 1, and a support platform 2 is arranged on the other side. Positioning components 9 are arranged on the side of the support platform 2 away from the fixed seat 1 and the other side of the movable seat 5. By arranging the adjustment component 3 inside the fixed seat 1, when in use, the adjustment component 3 can be controlled by rotating the rotating column 11 connected to the adjustment component 3 to push and pull the movable seat 5 horizontally. When the movable seat 5 is pushed and pulled horizontally, the movable seat 5 will move horizontally relative to the slidingly connected fixed seat 1, so that the distance between the two positioning components 9 can be adjusted, thereby facilitating the fixing of wind power gearboxes of different lengths, thereby enhancing the practicality of the fixing device of the present application.

[0055] In the embodiment of the present application, the adjustment component 3 is disposed inside the fixing base 1 , so that the adjustment component 3 can be better protected from damage by the fixing base 1 , thereby extending the service life of the fixing device.

[0056] In an embodiment of the present application, the side wall of the fixing seat 1 is also provided with a suppression component 6 located next to the rotating column 11, so that after the distance between the two positioning components 9 is adjusted by rotating the rotating column 11, the suppression component 6 can be used to limit the rotation of the rotating column 11, so that the adjusted fixing device of the present application can be used stably.

[0057] In some embodiments of the present application, a square embedding groove 10 is provided on the side of the fixed seat 1 connected to the movable seat 5. The fixed seat 1 is a "concave"-shaped structure, and the movable seat 5 is a "convex"-shaped structure with one side placed in the embedding groove 10. When one side of the movable seat 5 is completely embedded in the embedding groove 10, the movable seat 5 and the fixed seat 1 together form a square structure. At this time, the movable seat 5 and the fixed seat 1 achieve the minimum connection, and the entire wind turbine gearbox fixing device has the smallest footprint.

[0058] The fixing seat 1 is provided with a cavity for installing the adjustment component 3. Figure 3 and Figure 4 As shown, the adjustment assembly 3 includes a bidirectional worm 301 , a worm wheel 302 , a connecting rod 303 , a sleeve 304 , a screw 305 , a first bearing 306 , a second bearing 307 and a third bearing 308 .

[0059] Among them, the fixed seat 1 is connected to a bidirectional worm 301 arranged in the width direction of the fixed seat 1 through two first bearings 306 in the cavity of the installation and adjustment component 3, and the tooth surfaces on the left and right ends of the bidirectional worm 301 are respectively meshed with worm wheels 302 located below the bidirectional worm 301. One end of the bidirectional worm 301 extends out of the fixed seat 1 and is fixedly connected to the rotating column 11. The rotating column 11 can drive the bidirectional worm 301 to rotate when rotating. The setting of the rotating column 11 facilitates the operation of rotating the bidirectional worm 301. The inner walls of the two worm gears 302 are respectively fixed with connecting rods 303, and the two connecting rods 303 are respectively connected to sleeves 304 arranged along the length direction of the fixed seat 1. The other ends of the two connecting rods 303 are respectively covered with second bearings 307 and connected to the inner wall of the fixed seat 1 through the second bearings 307. The front and rear ends of the two sleeves 304 are respectively covered with third bearings 308 and are installed in the fixed seat 1 through the third bearings 308. The two sleeves 304 are symmetrically distributed on the left and right sides of the embedding groove 10. The two sleeves 304 are each connected with a screw 305 extending from the fixed seat 1 through the inner wall thread of the sleeve 304. One end of the two screws 305 extending from the fixed seat 1 is fixedly connected to the movable seat 5. When the two sleeves 304 rotate, the two screws 305 can move relative to the sleeve 304 in the length direction.

[0060] In the above embodiment, bearings are used for the connecting rod 303, the sleeve 304, and the bidirectional worm 301, and are respectively installed inside the fixing seat 1 through bearings. In this way, when operating the adjustment component 3, the difficulty of adjustment can be reduced, and the transmission and coordination of various components during adjustment can be smoother. In addition, the various parts of the adjustment component 3 cannot be seen from the outside of the fixing seat. With the protection of the fixing seat 1, the adjustment component 3 is also well protected.

[0061] When in use, the rotating column 11 fixedly connected to the bidirectional worm 301 can be rotated to realize the rotation of the bidirectional worm 301. The bidirectional worm 301 can simultaneously drive the two worm wheels 302 to rotate. The two worm wheels 302 drive the two sleeves 304 to rotate synchronously through the connecting rod 303. The two sleeves 304 push the two screws 305 to move. In this way, when the rotating column 11 is rotated in different directions, the two screws 305 can be used to push and pull the movable seat 5 to move, so that the screw 305 extends from the sleeve 304 or retracts into the sleeve 304. Since the movable seat 5 is slidably connected to the fixed seat 1, one end of the movable seat 5 slides along the embedded groove 10, so that the space exposed by the embedded groove 10 is changed, thereby increasing or reducing the distance between the two positioning components 9, one of which is connected to the support platform 2. It is used to position the front box body support leg of the wind power gearbox, and the other positioning component 9 connected to the movable seat 5 is used to position the rear box body support leg of the wind power gearbox, thereby facilitating the fixing of wind power gearboxes of different lengths.

[0062] In some embodiments of the present application, a gear ring support surface 201 is provided on the upper surface of the support platform 2, and the support platform 2 supports the gear ring of the wind turbine gearbox through the gear ring support surface 201. First connecting rings 4 are provided at the bottom ends of the left and right sides of the support platform 2. The two first connecting rings 4 can be cooperated with straps or chains to bundle the wind turbine gearbox, thereby improving the stability of the wind turbine gearbox when transporting the wind turbine gearbox. Second connecting rings 8 are provided on the left and right sides of the movable seat 5, which can also be cooperated with straps or chains to bundle the wind turbine gearbox, thereby further improving the stability of the wind turbine gearbox when transporting the wind turbine gearbox.

[0063] In some embodiments of the present application, Figure 1 and Figure 7 As shown, the positioning assembly 9 includes a positioning seat 91 , a positioning slot 92 , a bidirectional screw rod 93 , a clamping block 94 and a rotating disk 95 .

[0064] In this embodiment, the positioning seat 91 of the positioning assembly 9 connected to the support platform 2 is integrally connected to the support platform 2, and the positioning seat 91 of the positioning assembly 9 connected to the moving seat 5 is integrally connected to the moving seat 5. Among them, a positioning groove 92 of a square structure is provided at the top of the positioning seat 91, and the two supporting legs of the front box body of the wind power gearbox are inserted into the positioning groove 92 of the positioning seat 91 connected to the support platform 2, and the two rear box body supporting legs of the wind power gearbox are inserted into the positioning groove 92 of the positioning seat 91 connected to the moving seat 5. A bidirectional screw rod 93 located in the positioning seat 91 is connected to one side of the groove wall of the positioning groove 92 through a bearing, and a clamping block 94 is connected to the outer surface of both ends of the bidirectional screw rod 93 through a screw thread, and the contact part of the clamping block 94 and the positioning groove 92 is slidably connected, and one end of the bidirectional screw rod 93 passes through the side wall of the positioning seat 91 and is fixedly connected to a turntable 95. When in use, the hand-held turntable 95 is rotated, thereby driving the bidirectional screw 93 to rotate, and the bidirectional screw 93 can further drive the two clamping blocks 94 to move, so that the two clamping blocks 94 in one positioning component 9 are respectively fitted with the two supporting legs of the front box body of the gear box to clamp the front box body of the gear box, and the two clamping blocks 94 in the other positioning component 9 are respectively fitted with the two supporting legs of the rear box body of the gear box to clamp the rear box body of the rear gear box. Therefore, by setting the positioning component 9, it is convenient to clamp the supporting legs with different spacings within a certain range, which enhances practicality.

[0065] In some embodiments of the present application, two symmetrically distributed lifting ears 96 are provided on the outer side of the positioning seat 91. In this way, the two positioning seats 91 have a total of four lifting ears 96, so that the entire device can be lifted by the four lifting ears 96.

[0066] In some embodiments of the present application, the inner wall of the embedding groove 10 is provided with two symmetrical sliding grooves 12, and the inner walls of the two sliding grooves 12 are both slidably connected with dovetail bars 13, and the surfaces of the two dovetail bars 13 are both connected to the surface of the movable seat 5. During use and adjustment, when the screw rod 305 pushes and pulls the movable seat 5, the movable seat 5 drives the dovetail bar 13 to slide along the inner wall of the sliding groove 12, and the fixed seat 1 guides the movement of the movable seat 5 through the sliding groove 12 and the dovetail bar 13, thereby improving the stability of the movable seat 5 during adjustment and movement.

[0067] In some embodiments of the present application, Figure 2 , Figure 3 and Figure 5 As shown, the suppression assembly 6 includes a friction block 61 , a moving frame 63 , a first sliding rod 62 and a first compression spring 64 .

[0068] A guide groove 65 is provided at a position of the side wall of the fixed seat 1 near the rotating column 11, and a first slide bar 62 consistent with the length direction of the fixed seat 1 is connected to the guide groove 65, and a movable frame 63 extending out of the guide groove 65 is slidably connected to the inner wall of the guide groove 65, and a first slide hole 66 slidably connected to the surface of the first slide bar 62 is provided on the end surface of the movable frame 63 in the guide groove 65, and a first slide hole 66 is provided on the outer surface of the first slide bar 62 in a compressed state, and the two ends of the first compression spring 64 are respectively abutted against the movable frame 63 and the inner wall of the guide groove 65, and a friction block 61 is provided at the end of the movable frame 63 outside the guide groove 65, and a handle 67 is also provided on the top of the movable frame 63. Since the two ends of the first compression spring 64 are respectively in contact with the moving frame 63 and the inner wall of the guide groove 65, and the first compression spring 64 is in a compressed state, the natural extension force of the first compression spring 64 can act on the moving frame 63, thereby pushing the moving frame 63, so that the friction block 61 moves toward the rotating column 11 and then tightly contacts it, forming an effect similar to braking, prompting the friction block 61 to press the rotating column 11. The friction block 61 improves the stability of the rotating column 11 by increasing the sliding friction, thereby consolidating the adjustment effect.

[0069] In some embodiments of the present application, the surface of the rotating column 11 is coated with a wear-resistant coating, and the surface of the rotating column 11 is in friction and compression contact with the surface of the friction block 61. In the embodiment of the present application, the surface of the rotating column 11 is coated with a wear-resistant coating, which can protect the rotating column 11 through the wear-resistant coating and increase the service life of the rotating column 11.

[0070] Alternatively, if Figure 1 As shown, the wind turbine gearbox fixing device provided in the embodiment of the present application further includes a limit assembly 7, see Figure 2 and Figure 6 The limiting assembly 7 includes a connecting box 71, a second sliding rod 74, a push plate 72, a second compression spring 73, an insert rod 75 and a stopper 76.

[0071] In this embodiment, a limiting component 7 is added to the wind turbine gearbox fixing device, so that the convenience of using the device can be further improved when used in conjunction with the suppression component 6 and the rotating column 11. The locking cam 76 is provided on one side of the locking cam 76 which is located on the left side of the locking cam 76. The locking cam 76 is provided on the right side of the locking cam 76 to lock the locking cam 76. The operator then releases his hand on the push plate 72, and under the rebounding action of the second compression spring 73, the second compression spring 73 automatically pushes the push plate 72, and then pushes the insertion rod 75 out of the connection box 71, so that the insertion rod 75 just enters the insertion hole 69 of the insertion block 68, thereby fixing the movable frame 63, so that the other hand can be further released from the handle 67, so that when the rotating column 11 is rotated, the rotating column 11 can be better operated by hand, which is more convenient, and the rotating column 11 is not subject to the compression and friction contact of the friction block 61, and the operation can be achieved more easily.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
