[0031] like Figure 1 and Figure 2 As shown, this embodiment provides a gearbox clamping device, which includes a carrier 1, a first clamping member 2, a second clamping member 3, and a locking assembly 4. A plurality of first clamping members 2 and a plurality of second clamping members 3 are provided, and the plurality of first clamping members 2 are spaced apart along a first direction on the carrier 1. The plurality of second clamping members 3 are arranged one-to-one with the first clamping members 2. The second clamping members 3 and the first clamping members 2 enclose a limiting passage 21, which is used to clamp the axle 100 of the gearbox. The locking assembly 4 is used to lock to the carrier 1, the first clamping member 2, and the second clamping member 3. The locking assembly 4 includes a first screw 41 and a second screw 44. The first screw 41 is located on one side of the limiting passage 21 and passes through the first clamping member 2 and the second clamping member 3. The second screw 44 is located on the other side of the limiting passage 21 and passes through the first clamping member 2 and the second clamping member 3. The distance from the center of the limiting passage 21 to the first screw 41 is smaller than the distance from the center of the limiting passage 21 to the second screw 44.

[0032] In this embodiment, a plurality of first clamping members 2 and second clamping members 3 are provided, and a plurality of first clamping members 2 are arranged on the carrier 1 at intervals along the first direction to facilitate clamping and fixing of longer components such as the gearbox axle 100, thereby meeting the clamping requirements. A plurality of second clamping members 3 are arranged in a one-to-one correspondence with the first clamping members 2, so that the axle 100 can be clamped between the first clamping members 2 and the second clamping members 3. The second clamping members 3 and the first clamping members 2 form a limiting passage 21, which is used to clamp the axle 100 of the gearbox, thereby providing a clamping space for the axle 100. The locking assembly 4 is used to lock to the carrier 1, the first clamping member 2 and the second clamping member 3, so that the first clamping member 2 and the second clamping member 3 can be disassembled and assembled relative to the carrier 1. The locking assembly 4 includes a first screw 41 and a second screw 44. The first screw 41 is located on one side of the limiting passage 21 and passes through the first clamping member 2 and the second clamping member 3. The second screw 44 is located on the other side of the limiting passage 21 and passes through the first clamping member 2 and the second clamping member 3. The distance from the center of the limiting passage 21 to the first screw 41 is less than the distance from the center of the limiting passage 21 to the second screw 44. That is, the limiting passage 21 is eccentric relative to the first screw 41 and the second screw 44. When the gearbox clamping device is in use, the operator can adjust the installation direction of the first clamping member 2 and the second clamping member 3 according to the size of the axle 100 to change the position of the limiting passage 21 relative to the carrier 1, thereby adapting to the clamping operation of axles 100 of different specifications and sizes. Through the above arrangement, the gearbox clamping device of this embodiment can clamp axles 100 of different specifications and sizes, and has wider adaptability.

[0033] It should be noted that the gearbox clamping device of this embodiment can not only clamp the axle 100, but also components such as fan shafts or cables, without further limitation. Furthermore, the first direction of this embodiment is perpendicular to the paper and can be adjusted based on the specific clamping requirements of the axle 100. This will not be further explained here.

[0034] The specific structure of the gear box clamping device is described below:

[0035] Specifically, if Figure 1 and Figure 2 As shown, in this embodiment, both the first clamping member 2 and the second clamping member 3 are clamping blocks, which facilitate processing and assembly, and ensure the contact area between the clamping blocks and the axle 100, thereby improving the stability of the clamping operation. In other embodiments, the first clamping member 2 and the second clamping member 3 are both rod-shaped structures. As long as they can achieve the above-mentioned functions, the specific structures of these components are not further limited.

[0036] Specifically, if Figure 1and Figure 2 As shown, both the first clamping member 2 and the second clamping member 3 are provided with a limiting groove 31. The limiting groove 31 of the second clamping member 3 and the limiting groove 31 of the first clamping member 2 are arranged to form a limiting passage 21, and are clamped on both sides of the axle 100. Such an arrangement can firmly clamp the axle 100, avoiding looseness between the first clamping member 2 and the second clamping member 3 and the axle 100, thereby ensuring the stability and safety of the axle 100 during transportation.

[0037] More specifically, the cross-section of the retaining groove 31 extending along the first direction is V-shaped. When the axle 100 is clamped in the V-shaped retaining groove 31, both sides of the axle 100 are evenly squeezed, thereby ensuring stable and reliable clamping. In other embodiments, the cross-section of the retaining groove 31 extending along the first direction is arc-shaped. As long as the cross-section of the retaining groove 31 conforms to the shape of the axle 100, the specific shape of the cross-section is not particularly limited.

[0038] Specifically, an anti-slip pad is provided on the inner wall of the limiting groove 31, so that the first clamping member 2 and the second clamping member 3 can firmly fix the axle 100 during the clamping process, preventing the axle 100 from sliding or falling off, thereby improving the safety and reliability of the clamping operation. The anti-slip pad is made of rubber or silicone, and the specific material of the anti-slip pad is not limited here.

[0039] Specifically, if Figure 1 and Figure 2 As shown, in this embodiment, the locking assembly 4 further includes a first nut 42. A first aperture is defined in the carrier frame 1, and a second aperture is defined in the first clamping member 2. The first screw 41 and / or the second screw 44 are passed through the first and second apertures and connected to the first nut 42, thereby locking the first clamping member 2 to the carrier frame 1. Furthermore, the first nut 42 cooperates with the first screw 41 to secure the relative position between the carrier frame 1 and the first clamping member 2, ensuring that the first clamping member 2 does not become loose or fail relative to the carrier frame 1.

[0040] Specifically, the locking assembly 4 also includes a second nut 43. The second clamping member 3 is provided with a third aperture. The first screw 41 is inserted through the third aperture and connected to the second nut 43, thereby locking the second clamping member 3 to the first clamping member 2. This improves the stability and safety of the first and second clamping members 2 and 3 during the clamping operation. Furthermore, this arrangement makes the disassembly, assembly, and maintenance of the first and second clamping members 2 and 3 more convenient, making it easier for operators to operate.

[0041] Specifically, if Figure 2As shown, in other embodiments, the locking assembly 4 includes a third screw 46 and a third nut 45. The third screw 46 can be sequentially threadedly connected to the carrier 1, the first clamping member 2, and the second clamping member 3, thereby ensuring the overall stability and reliability of the gearbox clamping device. The third nut 45 is connected to the end of the second screw 44. By tightening the third nut 45, the friction between the carrier 1, the first clamping member 2, and the second clamping member 3 can be further increased, ensuring that they do not loosen during the clamping process.

[0042] Specifically, rollers are rotatably provided on the carrier 1 so that the carrier 1 can be moved and transported on the ground by the rollers, thereby improving working efficiency.

[0043] Specifically, if Figure 1 As shown, the carrier frame 1 includes a first vertical pole 11, a second vertical pole 12 and a connecting rod 13. The first vertical pole 11 and the second vertical pole 12 are parallel to each other and spaced apart. The two ends of the connecting rod 13 are respectively connected to the first vertical pole 11 and the second vertical pole 12. The first screw 41 and the second screw 44 are respectively connected to the connecting rod 13, thereby improving the overall stability of the carrier frame 1 and locking the first clamping member 2 and the second clamping member 3 on the carrier frame 1.

[0044] More specifically, the first clamping member 2 and the second clamping member 3 are both arranged between the first upright pole 11 and the second upright pole 12, and the distance from the center of the limiting passage 21 to the first upright pole 11 is 10 cm to 40 cm, thereby adapting to the clamping and transportation of axles 100 of different specifications and sizes.

[0045] The specific working process of the gear box clamping device is described as follows:

[0046] First, if Figure 1 As shown, the first screw 41 is passed through the carrier 1 and the first clamp 2 and connected to the first nut 42, thereby locking the first clamp 2 to the carrier 1. At this time, the distance between the center of the first screw 41 and the first vertical pole 11 is d1, and the distance between the center of the second screw 44 and the first vertical pole 11 is d2. Then, the gearbox axle 100 is placed on the limiting groove 31 of the first clamp 2, and the second clamp 3 is placed on the other side of the axle 100 away from the first clamp 2. The first screw 41 is passed through the second clamp 3 and connected to the second nut 43, thereby locking the second clamp 3 to the first clamp 2, so that the gearbox axle 100 is clamped between the first clamp 2 and the second clamp 3 to ensure the stability and safety of the clamping operation. At this time, as shown Figure 1 As shown, the distance between the center of the limiting channel between the first clamping member 2 and the second clamping member 3 and the first vertical pole 11 is L1, so as to adapt to the clamping and fixing operation of the gearbox axle 100 of the first specification.

[0047] It is understandable that if Figure 1 and Figure 2 As shown, when clamping and fixing a gearbox axle 100 of another specification, the operator can remove the second clamping member 3 from the first clamping member 2 by screwing the first nut 42 and the second nut 43, and remove the first clamping member 2 from the carrier 1. Then, after rotating the first clamping member 2 180 degrees around its own axis, the first clamping member 2 is locked to the carrier 1 again by the first screw 41 and the first nut 42. At this time, the distance between the center of the first screw 41 and the first vertical pole 11 is still d1, and the distance between the center of the second screw 44 and the first vertical pole 11 is still d2, that is, the installation position of the first clamping member 2 relative to the carrier 1 is not changed. The second clamping member 3 is then locked to the first clamping member 2, so that the distance between the center of the limiting channel between the first clamping member 2 and the second clamping member 3 and the first vertical pole 11 is L2 (as shown in FIG. Figure 2 As shown), since the distance from the center of the limiting passage 21 to the first screw 41 is smaller than the distance from the center of the limiting passage 21 to the second screw 44, that is, the limiting passage 21 is eccentrically arranged relative to the first screw 41 and the second screw 44, the first clamping member 2 and the second clamping member 3 are installed in reverse direction so that L1 is not equal to L2, thereby making the gearbox clamping device capable of adapting to the clamping and fixing operation of a gearbox axle 100 of another specification, and being more convenient and quick to use and having a wider adaptability.

[0048] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
