It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0032] like Figures 1-3As shown, this embodiment provides an output component hoisting mechanism for hoisting output components within equipment. The equipment has mounting holes, and the output component is detachably connected to these mounting holes. The output component hoisting mechanism includes a support 1 and a connecting assembly 2. Specifically, the support 1 includes a crossbeam 17 and two cantilever rods 11. The ends of the two cantilever rods 11 are connected to the crossbeam 17, and the two cantilever rods 11 are spaced apart. The ends of the two cantilever rods 11 away from the crossbeam 17 can extend into the mounting holes for installing the output component. The connecting assembly 2 is disposed between the two cantilever rods 11, and a roller 24 is provided at the top of the connecting assembly 2. The roller 24 is rotatably connected to the two cantilever rods 11, and the connecting assembly 2 is used to connect the output component. When it is necessary to disassemble or assemble the output component within the equipment, the two cantilever rods 11 extend into the mounting holes, and then the connecting assembly 2 connects to the output component. Finally, the connecting assembly 2 moves along the extension direction of the two cantilever rods 11 via rollers 24, thus achieving the hoisting of the output component and facilitating the replacement of the output component on the tower. In this embodiment, the rollers 24 facilitate the movement of the output component along the extension direction of the cantilever rods 11, simplifying operation and reducing the difficulty of the work.
[0033] Furthermore, the connecting component 2 is tactilely connected to the two cantilever rods 11 via rollers 24, which improves the smoothness of movement of the connecting component 2, reduces the force on a single cantilever rod 11, and prevents deformation of the cantilever rod 11. In this embodiment, the bracket 1 also includes an adjusting block 18, which is mounted on the crossbeam 17. The top surface of the adjusting block 18 is provided with an adjusting surface, and the cantilever rod 11 is connected to the adjusting surface so that the cantilever rod 11 is connected to the crossbeam 17 via the adjusting block 18. The adjusting surface can be tilted as needed so that the angle of the cantilever rod 11 relative to the crossbeam 17 meets the requirements.
[0034] In this embodiment, the device is a combination of a gearbox and a generator, and the output part is the output shaft inside the gearbox. The gearbox and the generator are provided with mounting holes for mounting the output shaft.
[0035] Preferably, such as Figure 2 and Figure 3 As shown, the connecting assembly 2 includes a clamp 21 with an adjustable inner diameter, which is used to connect to the side wall of the output assembly. In this embodiment, the output assembly is fixed by the clamp 21, and the diameter of the clamp 21 can be adjusted to accommodate shaft systems of different diameters, increasing its applicability. It should be noted that the clamp 21 is a common structure in the prior art. The clamp 21 includes two semi-circular blocks connected by screws. The screws can adjust the distance between the two semi-circular blocks to adjust the inner diameter of the clamp 21.
[0036] Preferably, the connecting assembly 2 further includes an end plate 22, which is connected to the clamp 21. The end plate 22 and the clamp 21 are spaced apart along the extension direction of the cantilever rod 11. The end plate 22 is used to connect the end of the output assembly. When the connecting assembly 2 connects to the output assembly, the clamp 21 fixes the side wall of the output assembly, and the end plate 22 connects to the end of the output assembly. The output assembly is connected to the connecting assembly 2 at two positions, which improves the connection stability and prevents the output assembly from moving relative to the clamp 21.
[0037] More preferably, such as Figure 2 and Figure 3 As shown, the connecting assembly 2 also includes an adjusting component 23. The end plate 22 is connected to the clamp 21 via the adjusting component 23. The adjusting component 23 is used to adjust the distance between the end plate 22 and the clamp 21 to accommodate different models of output components and improve versatility. Specifically, the adjusting component 23 includes an adjusting screw 231 and multiple adjusting nuts 232. The clamp 21 is provided with a third connecting hole, and the end plate 22 is provided with a fourth connecting hole. The adjusting screw 231 is sequentially connected to the first adjusting nut 232, the third connecting hole, the second adjusting nut 232, the third adjusting nut 232, the fourth connecting hole, and the fourth adjusting nut 232. By adjusting the position of the adjusting nut 232 relative to the screw, the distance between the clamp 21 and the end plate 22 can be adjusted to accommodate different models of output components, improving versatility. When the distance between the clamp 21 and the end plate 22 meets the requirements, the adjusting nut 232 is tightened so that the end faces of both ends of the third connecting hole and both ends of the fourth connecting hole are pressed against the adjusting nut 232, thus achieving relative fixation of the clamp 21, the end plate 22, and the adjusting screw 231. In this embodiment, there are two sets of adjusting components 23. The upper and lower ends of the end plate 22 are respectively connected to the clamp 21 through the adjusting components 23, which improves the installation stability and installation strength of the end plate 22.
[0038] Preferably, the fourth connecting hole is an oblong hole, so that the adjusting screw 231 has a certain amount of movement and installation error relative to the fourth connecting hole, thereby reducing the difficulty of assembly.
[0039] Furthermore, the bracket 1 includes a first connecting plate 12 and a first screw 13. The first connecting plate 12 is connected to one end of the cantilever rod 11 that extends into the mounting hole. The first connecting plate 12 is provided with a first connecting hole 121, and the first screw 13 passes through the first connecting hole 121 and is connected to the equipment. One end of the cantilever rod 11 is connected to the equipment via the first screw 13, and the other end is connected to the crossbeam 17, thereby increasing the strength of the cantilever rod 11 and improving the lifting strength.
[0040] Preferably, the bracket 1 includes a second connecting plate 14 and a second screw 15. The second connecting plate 14 is connected to the side wall of the cantilever rod 11, and the second connecting plate 14 is provided with a second connecting hole 141. The second screw 15 passes through the second connecting hole 141 and is connected to the equipment. The side wall of the cantilever rod 11 is connected to the equipment via the second screw 15, one end of the cantilever rod 11 is connected to the equipment via a first screw 13, and the other end is connected to the crossbeam 17. These three fixed positions further improve the strength of the cantilever rod 11 and increase the lifting strength.
[0041] Preferably, both the first connecting hole 121 and the second connecting hole 141 are arc-shaped holes. The first connecting hole 121 can be connected to the device by a plurality of first screws 13, and the second connecting hole 141 can be connected to the device by a plurality of second screws 15, thereby improving assembly strength.
[0042] Preferably, the bracket 1 further includes a first hinge block 16, one end of which is hinged to the side wall of the cantilever rod 11, and a second connecting plate 14 is hinged to the other end of the first hinge block 16. The second connecting plate 14 can be angled relative to the cantilever rod 11 through the first hinge block 16 to adapt to the installation environment of different equipment and improve versatility.
[0043] Furthermore, the cantilever 11 has a T-shaped cross-section and includes a vertical plate 111 and a horizontal plate 112. The vertical plate 111 is vertically connected to the horizontal plate 112. Multiple rollers 24 are symmetrically arranged on both sides of the vertical plate 111 and are tactilely connected to the top surface of the horizontal plate 112. In this embodiment, the vertical plate 111 improves the strength of the cantilever 11 and prevents deformation of the horizontal plate 112. The first hinge block 16 is hinged to the vertical plate 111, and the top of the connecting assembly 2 is tactilely connected to the top surface of the horizontal plate 112 via multiple rollers 24, facilitating the movement of the connecting assembly 2 relative to the cantilever 11.
[0044] In this embodiment, as Figure 1 and Figure 3 As shown, the connecting assembly 2 also includes a second hinge block 25. One end of the second hinge block 25 is hinged to the side wall of the clamp 21, and the other end of the second hinge block 25 is provided with multiple rollers 24 to facilitate adjustment of the position of the rollers 24 relative to the clamp 21 and improve assembly convenience. In this embodiment, a total of four rollers 24 are provided at the top of the second hinge block 25.
