Description

Technical Field

[0001] The utility model relates to the technical field of wind power fan coupling replacement devices, and particularly relates to a supporting device for replacing a fan coupling. Background Technique

[0002] In a wind power generator, as a key component of the fan equipment, the performance stability of the fan coupling directly affects the overall operation effect of the fan. During the maintenance and servicing of the fan, the replacement of the coupling is a common overhaul task. Whether it is to replace the fan coupling or the generator bearing, the fan coupling needs to be removed and then reinstalled. The fan coupling is relatively heavy, and there are a gearbox and a generator housing on both sides respectively, leaving little space for disassembly and assembly operations. When disassembling or installing, at least 3 - 4 people are required to cooperate. Among them, 2 people jointly hold the fan coupling, and the other 1 - 2 people disassemble and assemble the bolts on both sides. The operation is complex and the efficiency is low. At the same time, due to the small space, it is inconvenient to operate, and the physical strength of the lifting personnel is limited, which makes the fan coupling at risk of falling and causing personal injuries and property losses. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is: how to facilitate the disassembly and assembly of the fan coupling and reduce risks.

[0004] The technical solution of the utility model to solve the above technical problems is as follows:

[0005] The utility model provides a supporting device for replacing a fan coupling, including a bottom bracket. A plurality of running wheels are arranged on the lower side of the bottom bracket; a cross beam is arranged in the middle on the upper side of the bottom bracket, and at least two support rods are arranged on the cross beam. The height of the support rods relative to the cross beam is adjustable, and a locking component capable of locking itself on the cross beam is arranged on the support rods; a support fork is arranged at the upper end of the support rod, and the opening of the support fork faces upward and can be used to support the fan coupling.

[0006] The beneficial effects of the utility model are:

[0007] By adopting the utility model, the fan coupling is supported by two support forks, which facilitates the operator to disassemble and assemble the bolts at both ends of the fan coupling, eliminating the need for 2 people to hold the fan coupling. Only 1 - 2 people are required to operate the installation of the bolts, reducing the installation difficulty, improving the efficiency and safety; by adjusting the height of the support rods, the support fork can extend to the lower side of the installation position of the fan coupling, so as to adapt to the installation height of the fan coupling, with wide adaptability.

[0008] Based on the above technical solutions, the utility model can be further improved as follows.

[0009] Further, the locking member includes an internally threaded cylinder which is located above the cross beam or rotatably connected to the cross beam, and the internally threaded cylinder is threadedly connected to the support rod.

[0010] The height can be adjusted by rotating the internally threaded cylinder relative to the support rod, which is convenient for adjustment. After adjusting the height, the direction of the support fork can also be adjusted by rotating the internally threaded cylinder relative to the cross beam, facilitating the parallelism of the planes where the two support forks are located, and having good stability. In addition, when the fan coupling is not placed, the thread is less stressed, and the support rod can be held by hand to limit the position during height adjustment. When the fan coupling is placed, the two support forks are limited by the fan coupling, thus preventing the support rod from rotating, and only a tool such as a wrench is needed to rotate the internally threaded cylinder to adjust the height.

[0011] Further, a plurality of handles are provided on the outer side of the internally threaded cylinder.

[0012] By turning the internally threaded cylinder with the help of the handle, a wrench can be saved, which is convenient for adjusting the height of the support rod and easy to operate.

[0013] Further, the internally threaded cylinder is located above the cross beam, and a backing plate is also provided below the internally threaded cylinder.

[0014] It is convenient to increase the stress-bearing area on the upper side of the cross beam, with relatively uniform stress and avoiding cracks. At the same time, the backing plate can rotate, reducing the rotation resistance of the internally threaded cylinder.

[0015] Further, a central beam is provided inside the bottom bracket, and the lower end of the support rod penetrates through the central beam.

[0016] It is convenient to jointly bear the bending moment of the support rod with the cross beam, reducing the stress on the cross beam, having large structural strength, and improving the stability of the support rod at the same time.

[0017] Further, the bottom bracket is in the shape of a frustum of a pyramid, and reinforcing vertical plates are provided on opposite side faces of the bottom bracket, and both ends of the central beam are connected to the reinforcing vertical plates.

[0018] The upper end of the reinforcing vertical plate can share the pressure transmitted from the cross beam to the bottom bracket. The central beam connects the middle parts of the reinforcing vertical plates to form a whole, improving the structural strength and reducing the risk of compressive instability of the vertical rods at various parts of the reinforcing vertical plates and the bottom bracket.

[0019] Further, the bottom bracket is made of angle steel by welding.

[0020] It has large structural strength and good stability.

[0021] Further, it further includes a diagonal bracing plate. The upper end of the diagonal bracing plate is connected to the cross beam, the lower end of the diagonal bracing plate is connected to the reinforcing vertical plate, and the support rod penetrates through the diagonal bracing plate.

[0022] The diagonal bracing plate, cross beam and reinforcing vertical plate form a triangular frame, improving the structural stability; the diagonal bracing plate can share the bending moment in the middle of the support rod, reducing the deflection of the support rod, enhancing the stability and reducing the risk of buckling of the support rod under compression.

[0023] Furthermore, there are two diagonal bracing plates. The upper ends of the diagonal bracing plates are connected to the middle of the cross beam, and the lower ends of the diagonal bracing plates are respectively connected to two reinforcing vertical plates.

[0024] The load borne by the cross beam can be transmitted to the diagonal bracing plate, reducing the deflection in the middle of the cross beam, having good stability and enhancing the strength.

[0025] Furthermore, the support fork is U-shaped or semi-circular.

[0026] The arc-shaped inner side wall and bottom wall of the support fork can fully contact the fan coupling, increasing the contact area, making the force evenly distributed, reducing the stress, avoiding damage to the support fork and having good reliability. Description of the Drawings

[0030] The principles and features of the present utility model will be described below in conjunction with the drawings. The examples given are only used to explain the present utility model and are not intended to limit the scope of the present utility model.

[0031] The present utility model is referred to Figure 1 .

[0032] The present utility model provides a support device for replacing a fan coupling, including a bottom bracket 1. A plurality of traveling wheels 5 are provided on the lower side of the bottom bracket 1; in the middle of the upper side of the bottom bracket 1, there is a cross beam 2. At least two support rods 3 are provided on the cross beam 2. The height of the support rods 3 relative to the cross beam 2 is adjustable, and a locking member capable of locking itself on the cross beam 2 is provided on the support rods 3; at the upper end of the support rod 3, there is a support fork 4. The opening of the support fork 4 faces upward and can be used to support the fan coupling.

[0033] Principle:

[0034] When disassembling the fan coupling, the bottom bracket 1 is moved to the lower side of the fan coupling through the walking wheels 5. The operator adjusts the height of the support rod 3 so that the two support forks 4 support the lower side of the fan coupling. Then, the support rod 3 is locked to the cross beam 2 through the locking component, so that the force on the support rod 3 can be transmitted to the cross beam 2. At this time, the operator can disassemble the bolts at both ends of the fan coupling. After the disassembly is completed, the bottom bracket 1 can be pushed to move through the walking wheels 5, so as to leave the original position. When installing the fan coupling, the newly replaced fan coupling is placed on the support fork 4. Then, the bottom bracket 1 can be pushed to move to the lower side of the installation position, and the height of the support rod 3 is adjusted (the height can also be adjusted first and then the fan coupling is placed). The support rod 3 is locked to the cross beam 2 through the locking component. Then, the operator can install the bolts at both ends of the fan coupling. Two people who hold up the fan coupling are saved, and only 1-2 people are needed to operate the installation of the bolts. At least 3-4 people are required to cooperate. Among them, two people hold up the fan coupling together, and the other 1-2 people disassemble and install the bolts on both sides. The operation is complex and the efficiency is low. At the same time, due to the small space, it is inconvenient to operate, and the physical strength of the holding personnel is limited, so there is a risk that the fan coupling will fall and cause personal injury and property loss.

[0035] Preferably, the walking wheels 5 are self-locking walking wheels.

[0036] By adopting the utility model, the fan coupling is supported by two support forks 4, which is convenient for the operator to disassemble and install the bolts at both ends of the fan coupling. Two people who hold up the fan coupling are saved, and only 1-2 people are needed to operate the installation of the bolts. The installation difficulty is reduced, and the efficiency and safety are improved. By adjusting the height of the support rod 3, the support fork 4 can extend to the lower side of the installation position of the fan coupling, so that the installation height of the fan coupling can be adapted, and the adaptability is wide.

[0037] Further, the locking component includes an internal thread cylinder 6. The internal thread cylinder 6 is located on the upper side of the cross beam 2 or is rotatably connected to the cross beam 2. The internal thread cylinder 6 is threadedly connected to the support rod 3.

[0038] Note: The locking component can also be a structure such as a bolt. A plurality of pin holes are correspondingly opened on the support rod 3 for the bolt. Since the support rod 3 penetrates the cross beam 2, when the bolt is inserted into the pin hole and both ends of the bolt lap on the cross beam 2, the load of the support rod 3 can be transmitted to the cross beam 2 through the bolt. An internal thread cylinder 6 can also be arranged on the lower side of the cross beam 2. The two internal thread cylinders 6 are clamped on both sides of the cross beam 2 to improve the stability of the support rod 3 relative to the cross beam 2.

[0039] Preferably, nuts are provided on the lower side of the cross beam 2. The nuts and the internal thread cylinder 6 are clamped on both sides of the cross beam 2, which can fix the support rod 3 to the cross beam 2 and play a stabilizing effect. At the same time, structures such as the central beam 9, the reinforcing vertical plate 10, and the inclined support plate 11 can be omitted, reducing the weight of the device and facilitating handling.

[0040] The height can be adjusted by rotating the internally threaded cylinder 6 relative to the support rod 3, which is convenient for adjustment. After adjusting the height, the direction of the support fork 4 can also be adjusted by rotating the internally threaded cylinder 6 relative to the cross beam 2, which is convenient for making the planes where the two support forks 4 are located parallel to each other, and has good stability. In addition, when the fan coupling is not placed, the thread is less stressed, and the support rod 3 can be held by hand to limit the position when adjusting the height. When the fan coupling is placed, the two support forks 4 are limited by the fan coupling, so that the rotation of the support rod 3 is avoided, and only a tool such as a wrench is needed to rotate the internally threaded cylinder 6 to adjust the height.

[0041] Furthermore, a plurality of handles 7 are provided on the outer side of the internally threaded cylinder 6.

[0042] By leveraging the handles 7 to rotate the internally threaded cylinder 6, a wrench can be saved, which is convenient for adjusting the height of the support rod 3 and is easy to operate.

[0043] Furthermore, the internally threaded cylinder 6 is located above the cross beam 2, and a backing plate 8 is also provided below the internally threaded cylinder 6.

[0044] Note: The backing plate 8 can be replaced by a thrust bearing; to reduce the rotational resistance of the internally threaded cylinder 6.

[0045] It is convenient to increase the force-bearing area on the upper side of the cross beam 2, and the force is relatively uniform, avoiding the generation of cracks. At the same time, the backing plate 8 can rotate, reducing the rotational resistance of the internally threaded cylinder 6.

[0046] Furthermore, a central beam 9 is provided inside the bottom bracket 1, and the lower end of the support rod 3 penetrates through the central beam 9.

[0047] It is convenient to jointly bear the bending moment of the support rod 3 with the cross beam 2, reduce the stress on the cross beam 2, has great structural strength, and improves the stability of the support rod 3 at the same time.

[0048] Furthermore, the bottom bracket 1 is in the shape of a frustum of a pyramid, and reinforcing vertical plates 10 are provided on the opposite two side faces of the bottom bracket 1, and both ends of the central beam 9 are connected to the reinforcing vertical plates 10.

[0049] The upper end of the reinforcing vertical plate 10 can share the pressure transmitted from the cross beam 2 to the bottom bracket 1. The central beam 9 connects the middle parts of the reinforcing vertical plates 10 to form an integral body, improving the structural strength and reducing the risk of buckling of the vertical rods at various places on the reinforcing vertical plates 10 and the bottom bracket 1.

[0050] Furthermore, the bottom bracket 1 is made of angle steel by welding.

[0051] It has great structural strength and good stability.

[0052] Furthermore, it further includes a diagonal bracing plate 11. The upper end of the diagonal bracing plate 11 is connected to the cross beam 2, the lower end of the diagonal bracing plate 11 is connected to the reinforcing vertical plate 10, and the support rod 3 penetrates through the diagonal bracing plate 11.

[0053] The diagonal bracing plate 11, the cross beam 2 and the reinforcing vertical plate 10 form a triangular frame, improving the structural stability; the diagonal bracing plate 11 can share the bending moment in the middle of the support rod 3, reducing the deflection of the support rod 3, improving the stability and reducing the risk of buckling of the support rod 3 under compression.

[0054] Furthermore, there are two diagonal bracing plates 11. The upper ends of the diagonal bracing plates 11 are connected to the middle of the cross beam 2, and the lower ends of the diagonal bracing plates 11 are respectively connected to the two reinforcing vertical plates 10.

[0055] The load borne by the cross beam 2 can be transmitted to the diagonal bracing plate 11, reducing the deflection in the middle of the cross beam 2, having good stability and improving the strength.

[0056] Furthermore, the support fork 4 is U-shaped or semi-circular.

[0057] The arc-shaped inner side wall and the bottom wall of the support fork 4 can fully contact with the fan coupling, increasing the contact area, having uniform stress, reducing the stress, avoiding damage to the support fork 4 and having good reliability.
