[0032] At present, in the wind power industry, in order to enhance the shear resistance of the connection between the fan main shaft and the gear box, multiple sets of hollow pins need to be evenly installed at the connection between the fan main shaft and the gear box. Existing hollow pins are mostly installed manually. During installation, the installer first moves the hollow pin frozen by liquid nitrogen to the fan main shaft, and then installs the hollow pin in the corresponding hole by knocking, hydraulic (gas) pressure pushing device, etc. However, manual installation has the problems of large workload and low efficiency.

[0033] Based on this, the present invention proposes a pin installation device for installing the pin of the fan main shaft, aiming to solve the problem of large workload and low efficiency when manually installing the pin of the fan main shaft. Figures 1 to 3 This is a schematic structural diagram of the pin shaft installation device provided by the present invention.

[0034] See also Figures 1 to 3 In one embodiment of the present invention, the pin shaft installation device 100 includes a base 1, a rotating structure 2 and a pushing structure 3, wherein the base 1 is used to be installed on the main shaft of the fan, the rotating structure 2 includes a rotating seat 21 and a rotating driving device 22, the rotating seat 21 is rotatably installed on the base 1, the rotating driving device 22 is drivingly connected to the rotating seat 21, and is used to drive the rotating seat 21 to rotate, the pushing structure 3 includes a pushing frame 31 and a pushing driving device 32, the pushing frame 31 is movably installed on the rotating seat 21 along the rotation axis direction of the rotating seat 21, the pushing frame 31 is provided with a mounting portion 311 for the pin shaft to be installed, and the pushing driving device 32 is drivingly connected to the pushing frame 31, and is used to drive the pushing frame 31 to move along the rotation axis direction of the rotating seat 21.

[0035] In the technical solution of the present invention, when it is necessary to install multiple pins on the main shaft and gear box of the fan, the base 1 is first installed on the main shaft of the fan, and then the push drive device 32 drives the push frame 31 to move, driving the mounting portion 311 to move along the rotation axis direction of the swivel seat 21, so as to press the pin installed with the mounting portion 311 into the hole of the main shaft and gear box of the fan. After the pin is pressed in, the push drive device 32 drives the push frame 31 to move, driving the mounting portion 311 to withdraw, and then the swivel drive device 22 drives the swivel seat 21 to rotate, so as to adjust the position of the mounting portion 311 and reinstall the pin, and repeat the above steps until all the pins are installed. In this way, by setting the base 1, the The rotary structure 2 is installed on the main shaft of the fan, and the pushing drive device 32 is provided to drive the pushing frame 31 to move, so that the mounting portion 311 can push the pin to move along the rotation axis direction of the rotating seat 21, so as to press the pin into the hole between the main shaft of the fan and the gear box, so as to connect the main shaft of the fan with the gear box. At the same time, the rotary drive device 22 is provided to drive the rotating seat 21 to rotate, so that the pushing structure 3 can rotate in the main shaft of the fan, so as to adjust the position of the mounting portion 311, so that the pushing structure 3 can install the pins at different positions, so that the pin installation device 100 can automatically install the pins between the main shaft of the fan and the gear box, thereby solving the problem of large workload and low efficiency when manually installing the pins of the main shaft of the fan.

[0036] Furthermore, the number of the mounting portion 311 may be one, two, three, four, etc., which is not limited in the present invention. Specifically, in this embodiment, please refer to Figure 1 A plurality of mounting portions 311 are provided, and the plurality of mounting portions 311 are spaced apart along the circumference of the push frame 31. Thus, by providing the mounting portions 311, on the one hand, the push structure 3 can be installed with a plurality of pins at the same time, which helps to improve the installation efficiency of the pin mounting device 100; on the other hand, the force on the push frame 31 can be kept balanced, so as to minimize the torque of the push frame 31 and reduce the probability of the push structure 3 getting stuck. Furthermore, there are various arrangements of the plurality of mounting portions 311. The plurality of mounting portions 311 may be evenly arranged or non-uniformly arranged along the circumference of the push frame 31. The present invention does not limit this. However, if a non-uniform arrangement is adopted, it is not easy to make the reaction force of the plurality of mounting portions 311 on the push frame 31 be located at the center of the push frame 31. In the present embodiment, the plurality of mounting portions 311 are evenly arranged along the circumference of the push frame 31 to minimize the torque of the plurality of mounting portions 311 on the push frame 31.

[0037] In one embodiment of the present invention, although the more the mounting parts 311 are, the higher the efficiency of the pin mounting device 100 is, the more the mounting parts 311 are, the more complex the pin mounting device 100 is, and the higher the cost is. At the same time, the space of the fan main shaft is limited, which will also affect the number of the mounting parts 311. Specifically, in this embodiment, three mounting parts 311 are provided, which can not only ensure the efficiency of the pin mounting device 100, but also facilitate balancing the force of the push frame 31.

[0038] In one embodiment of the present invention, the push frame 31 is provided with a mounting sleeve, and the mounting portion 311 includes an inner tube of the mounting sleeve. Thus, by providing the mounting sleeve, a pin is installed, so that the push structure 3 can install the pin between the fan main shaft and the gear box to improve the shear resistance of the connection between the fan main shaft and the gear box. Of course, in other embodiments, the mounting portion 311 can also be a mounting groove provided on the push frame 31, etc., as long as the pin can be installed on the push frame 31, and the present invention does not limit this.

[0039] In one embodiment of the present invention, there are multiple ways of connecting the mounting portion 311 and the push frame 31. The mounting portion 311 may be welded to the push frame 31 or screwed to the push frame 31, etc., and the present invention does not limit this. Specifically, in this embodiment, the mounting portion 311 is detachably mounted on the push frame 31. In this way, a detachable connection is adopted so that the mounting portion 311 can be replaced as needed to adapt to pins of different sizes, so that pins of different sizes can be mounted on the push frame 31, so that the push structure 3 can be installed with pins of different sizes, thereby facilitating the versatility of the pin mounting device 100. Furthermore, there are multiple detachable connection structures, for example, a bolt connection structure, a buckle connection structure, etc., and the present invention does not limit this.

[0040] It should be noted that the above two related technical features: "the pushing frame 31 is provided with a mounting sleeve, and the mounting portion 311 includes an inner tube of the mounting sleeve", and "the mounting portion 311 can be detachably mounted on the pushing frame 31" can be set selectively or simultaneously, and the present invention does not limit this.

[0041] When installing the pin shaft, the pin shaft needs to be inserted into the holes of the fan main shaft and the gear box. The assembly accuracy is high. For this reason, in one embodiment of the present invention, please refer to Figure 3 A pressure detection device 4 is provided in the installation sleeve to detect the pressure of the pin shaft in the installation sleeve. In this way, by providing the pressure detection device 4, when the pin shaft is pushed out by the pushing structure 3, the pressure of the pin shaft on different circumferential positions of the installation sleeve can be detected to determine whether the pin shaft is tilted, thereby helping to ensure the alignment effect of the shaft hole.

[0042] It can be understood that there are multiple types of pressure detection device 4, and the pressure detection device 4 can be a strain gauge sensor, a capacitive sensor, or an optical fiber pressure sensor, etc. The present invention does not limit this. Specifically, in this embodiment, the pressure detection device 4 is a strain gauge sensor, which can detect both the magnitude and direction of pressure and is easy to be set in the installation sleeve.

[0043] The number of the pressure detection device 4 can be one or more, and the present invention does not limit this. Specifically, in this embodiment, please refer to Figure 3 A plurality of pressure detection devices 4 are provided, and the plurality of pressure detection devices 4 are arranged at intervals along the circumference of the mounting sleeve. Thus, by providing a plurality of pressure detection devices 4, the pressure of the pin at different positions in the mounting sleeve rod can be detected to determine the inclination direction of the pin, thereby facilitating adjustment of the pin.

[0044] Furthermore, the plurality of pressure detection devices 4 may be two, three, or four, etc., and the present invention does not limit this. Specifically, in the present embodiment, four pressure detection devices 4 are provided, and the four pressure detection devices 4 include two first pressure sensors and two second pressure sensors. The two first pressure sensors are arranged at intervals along the radial direction of the push frame 31, and the two second pressure sensors are arranged at intervals along the circumferential direction of the push frame 31. In this way, by providing two first pressure sensors and two second pressure sensors, the inclination direction of the pin shaft can be directly determined without the need for additional conversion, thereby facilitating the adjustment of the pin shaft.

[0045] Please note that Figure 3 When the pressure of the first pressure sensor on the inside is larger, it means that the pin is tilted downward. On the contrary, when the pressure of the first pressure sensor on the outside is larger, it means that the pin is tilted upward. Similarly, when the pressure of the second pressure sensor on the left is larger, it means that the pin is tilted to the left. On the contrary, when the pressure of the second pressure sensor on the right is larger, it means that the pin is tilted to the right. In this way, by setting two first pressure sensors and two second pressure sensors, the tilting direction of the pin can be directly determined. Of course, in its embodiment, the two first pressure sensors and the two second pressure sensors can also be arranged in other ways, for example, the two first pressure sensors are arranged at intervals upward and to the right, and the two second pressure sensors are arranged at intervals upward and to the left. However, such a setting requires the pressure at each position to be decomposed, and the tilting direction of the pin can be determined only after calculation, which is more complicated.

[0046] In one embodiment of the present invention, see Figure 1 and Figure 2 The rotary structure 2 also includes a rotary bearing 23. One of the inner ring and the outer ring of the rotary bearing 23 is arranged on the base 1, and the other is the rotary seat 21. Since the rotary bearing 23 can withstand large axial, radial and overturning moment loads and has high processing accuracy, it can ensure low installation errors and ensure accurate positioning of rotating parts. Therefore, the rotary bearing 23 is adopted. On the one hand, it can bear a large load, and on the other hand, it can ensure the rotation accuracy of the rotary structure 2, so as to facilitate the alignment of the pin shaft. Of course, in other embodiments, the rotary seat 21 can also be a shaft hole structure rotatably installed on the base 1, etc., and the present invention does not limit this.

[0047] Furthermore, there are multiple ways to connect the slewing bearing 23 to the base 1. The slewing bearing 23 and the base 1 can be connected by bolts or by welding, etc., and the present invention does not limit this. Similarly, there are multiple ways to connect the slewing bearing 23 and the slewing seat 21. The slewing bearing 23 and the slewing seat 21 can be connected by bolts or by welding, etc., and the present invention does not limit this.

[0048] In one embodiment of the present invention, see Figure 1 and Figure 2 The rotary drive device 22 includes a rotary drive motor 221 and a rotary transmission structure 222. The rotary drive motor 221 is arranged on the rotary seat 21. The rotary transmission structure 222 includes a gear ring and a gear that mesh with each other. The gear ring is arranged on the inner ring of the rotary support 23. The gear transmission is connected to the rotary drive motor 221. In this way, the rotary drive motor 221 is arranged to drive the gear to rotate, and the gear ring and the gear are arranged to transmit the torque of the rotary drive motor 221 to the base 1, so that the rotary seat 21 can rotate relative to the base 1, so as to adjust the position of the mounting portion 311.

[0049] It is understandable that the number of the rotary drive device 22 is not limited, and can be one or more. Specifically, in this embodiment, multiple rotary drive devices 22 are provided, and multiple rotary drive devices 22 are arranged at intervals along the circumference of the rotary seat 21, so as to ensure that the pin shaft installation device 100 has sufficient power to drive the rotary seat 21 to rotate. Further, three rotary drive devices 22 are provided to reduce the cost of the rotary structure 2 while ensuring the power of the rotary structure 2.

[0050] In one embodiment of the present invention, see Figure 1 The push drive device 32 includes a linear drive structure, which has a fixed end and a drive end relative to each other, one of which is provided on the rotary seat 21, and the other is provided on the push frame 31.

Furthermore, there are many types of linear drive structures, for example, it can be a drive cylinder, it can also be a drive oil cylinder, etc., and the present invention does not limit this.

[0051] It is understandable that, in other embodiments, the push drive device 32 may also be a combination structure of a motor and a lead screw structure, etc., and the present invention is not limited to this.

[0052] There are many ways to connect the fixed end to the swivel seat 21. The fixed end and the swivel seat 21 can be connected by welding or bolts, etc., and the present invention does not limit this. Specifically, in this embodiment, the fixed end is detachably mounted on the swivel seat 21. In this way, a detachable structure is adopted to facilitate the loading and unloading of the linear drive structure, so that the user can replace the linear drive structure as needed.

In this way, a detachable structure is adopted to facilitate the loading and unloading of the pushing frame 31, so that the user can adjust the rotation radius of the mounting portion 311 by replacing the pushing frame 31, so that the position of the mounting portion 311 can be adjusted along the radial direction of the pushing frame 31, thereby helping to improve the versatility of the pin shaft mounting device 100. It can be understood that there are many detachable structures, for example, it can be a bolt connection structure or a buckle connection structure, etc., and the present invention does not limit this.

[0054] It should be noted that the above two related technical features: "the fixed end can be detachably mounted on the rotating seat 21" and "the pushing frame 31 can be detachably mounted on the driving end" can be set selectively or simultaneously, and the present invention does not limit this.
