Description

Technical Field

[0001] This utility model relates to the technical field of fan turning equipment, and in particular to an automatic turning device. Background Technology

[0002] An induced draft fan is a device that draws air from a system by generating negative pressure through the rotation of an impeller. It is usually installed at the tail end of a boiler to extract hot flue gas from the furnace. According to the maintenance schedule, the induced draft fan needs to be rotated once a week.

[0003] Because large wind turbines have large impellers and are connected to high-voltage motors via a fan coupling, the protective cover of the fan coupling needs to be removed when rotating the turbine, and then two people need to work together to rotate the impeller.

[0004] The existing technology has at least the following problems: First, it requires the cooperation of multiple people to realize the operation of the machine, which wastes manpower; second, manual operation of the machine is time-consuming and labor-intensive, and the labor intensity of the staff is relatively high. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by developing an automatic turning device. This invention enables single-person turning of the machine, reduces the labor intensity of workers, and effectively improves the efficiency and effectiveness of turning.

[0006] The technical solution of this utility model to solve the technical problem is as follows: an automatic turning device, including a base, a lifting device on the top of the base, a support platform on the lifting end of the top of the lifting device, and a drive wheel and a support wheel respectively provided at both ends of the support platform through bearing seats.

[0007] As an optimization, the top height of the drive wheel is less than or equal to the top height of the support wheel. This allows for easy placement of the support wheel on the other side of the wind turbine coupling, preventing insufficient height between the wind turbine coupling and the ground.

[0008] As an optimization, the lifting device includes two sets of worm gear screw jacks, a coupling, and a crank. The input shafts of the two sets of worm gear screw jacks are connected to each other via the coupling, and the crank is connected to the input shaft of one set of worm gear screw jacks. By setting two sets of worm gear screw jacks, the stability of lifting can be improved; by setting a coupling, the two sets of worm gear screw jacks can be raised and lowered synchronously; by setting a crank, it is convenient for operators to adjust the lifting height and to check at any time whether the drive wheel and support wheel are in contact with the fan coupling.

[0009] As an optimization, the lifting device is a scissor lift, which improves the stability of the lifting process.

[0010] As an optimization, the base is equipped with several sets of support blocks at its bottom. By setting the support blocks, a gap is created between the base and the ground, which facilitates the adjustment of the base's position during installation. This allows the drive wheel and support wheel to be positioned below the fan coupling, and after being raised, the drive wheel and support wheel can simultaneously abut against the fan coupling. It also prevents the base from shifting on the ground and avoids misalignment between the drive wheel and support wheel and the fan coupling.

[0011] As an optimization, a drive motor and a battery are also included. The output of the drive motor is connected to the drive wheel, and the battery is electrically connected to the drive motor. By setting up the drive motor, the drive wheel can be rotated; by setting up the battery, the drive motor can be powered.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The base supports the lifting device; the lifting device raises the drive wheel and support wheel during rotation, allowing them to engage with the fan coupling; after rotation, the drive wheel and support wheel are lowered, disengaging from the fan coupling. A support platform mounts the drive wheel and support wheel; the drive wheel rotates the fan coupling, thus rotating the impeller and completing the rotation operation; the support wheel supports the fan coupling and works in conjunction with the drive wheel for rotation. This invention allows for single-person rotation, reduces worker workload, and effectively improves the efficiency and effectiveness of rotation. Attached Figure Description

[0017] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0018] Example 1

[0019] Figure 1 and Figure 2 As one embodiment of this utility model, such as Figure 1 and Figure 2As shown, an automatic turning device includes a base 1, a lifting device 2 on the top of the base 1, a support platform 3 on the lifting end of the top of the lifting device 2, and a drive wheel 4 and a support wheel 5 respectively on both ends of the support platform 3 via bearing seats.

[0020] The base 1 supports the lifting device 2. The lifting device 2 allows the drive wheel 4 and support wheel 5 to be raised during rotation, bringing them into contact with the fan coupling. After rotation, the drive wheel 4 and support wheel 5 are lowered, disengaging from the fan coupling. The support platform 3 allows the drive wheel 4 and support wheel 5 to be installed. The drive wheel 4 drives the fan coupling to rotate, thus rotating the impeller and completing the rotation operation. The support wheel 5 supports the fan coupling and works in conjunction with the drive wheel 4 for rotation.

[0021] like Figure 1 and Figure 2 As shown, the top height of the drive wheel 4 is less than or equal to the top height of the support wheel 5. This allows the support wheel 5 to be easily positioned on the other side of the fan coupling during installation, preventing insufficient height between the fan coupling and the ground.

[0022] like Figure 1 and Figure 2 As shown, the lifting device 2 includes two sets of worm gear screw jacks 6, a coupling 7, and a crank 8. The input shafts of the two sets of worm gear screw jacks 6 are connected to each other through the coupling 7, and the crank 8 is connected to the input shaft of one set of worm gear screw jacks 6. By setting two sets of worm gear screw jacks 6, the stability of lifting can be improved and the labor intensity of workers can be reduced; by setting the coupling 7, the two sets of worm gear screw jacks 6 can be raised and lowered synchronously; by setting the crank 8, workers can easily crank it to adjust the height of the lifting end of the worm gear screw jack 6, and workers can easily check whether the drive wheel 4 and the support wheel 5 are in contact with the fan coupling.

[0023] like Figure 1 and Figure 2 As shown, the bottom of the base 1 is provided with several sets of support blocks 9. By setting the support blocks 9, a gap is made between the base 1 and the ground, which facilitates the adjustment of the position of the base 1 during arrangement, so that the drive wheel 4 and the support wheel 5 are located below the fan coupling. After being raised, the drive wheel 4 and the support wheel 5 can simultaneously abut against the fan coupling, and it can also prevent the base 1 from shifting on the ground and avoid misalignment between the drive wheel 4 and the support wheel 5 and the fan coupling.

[0024] like Figure 2 As shown, it also includes a drive motor 10 and a battery. The output terminal of the drive motor 10 is connected to the drive wheel 4, and the battery is electrically connected to the drive motor 10. By setting the drive motor 10, the drive wheel 4 can be driven to rotate; by setting the battery, the drive motor 10 can be powered.

[0025] Example 2

[0026] The difference between this and the first embodiment is that the lifting device 2 is a scissor lift. This improves the stability of the lifting and reduces the labor intensity of the workers.

[0027] In use, this application is positioned below the fan coupling, and the position of the base 1 is adjusted so that the drive wheel 4 and support wheel 5 are located below the fan coupling, ensuring that the drive wheel 4 and support wheel 5 can simultaneously abut against the fan coupling after being raised. During rotation, the operator raises the lifting device 2, so that the drive wheel 4 and support wheel 5 simultaneously abut against the fan coupling, and then starts the drive motor 10, driving the drive wheel 4 to rotate. The drive wheel 4 drives the fan coupling to rotate, thereby driving the impeller to rotate, completing the rotation operation. After the rotation is completed, the operator lowers the lifting device 2 and stops the drive motor 10. This application does not need to be removed from under the fan coupling and can be used directly for the next rotation. It should be noted that the drive motor 10 can be a hub motor built into the drive wheel 4, or a motor set on the support platform 3 or bearing seat. This utility model can realize single-person rotation, reduce the labor intensity of the operator, and effectively improve the efficiency and effect of rotation.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
