[0037] The following exemplary embodiments are described in detail, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numbers in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible implementations consistent with the present invention. Instead, they are merely examples of apparatuses and methods consistent with certain aspects of the present invention, as detailed in the appended claims.

[0038] In the prior art, an axial flow fan includes a housing, a shaft, and a bearing. The shaft is connected to the inner ring of the bearing, and the outer ring of the bearing is connected to the housing to support and secure the shaft. When removing the shaft, it is typically struck with a hammer to remove it from the bearing. However, striking the shaft with a hammer to move it causes the housing and bearing to move with it, making shaft removal inconvenient and inefficient. This results in low maintenance efficiency for the axial flow fan. Furthermore, striking the shaft with a hammer can easily cause it to deform or even damage, resulting in poor shaft maintenance.

[0039] Based on this, an embodiment of the present application provides a maintenance platform for an axial flow fan, including a support frame and a hydraulic drive component. The support frame has an avoidance hole and at least one accommodating groove. The accommodating groove matches a portion of the shell to fix the shell through the accommodating groove, and then fix the shell on the support frame to prevent the shell and the bearing from moving, and facilitate the movement of the rotating shaft relative to the bearing and disengagement from the bearing, thereby improving the maintenance efficiency of the axial flow fan. At the same time, the rotating shaft can correspond to the avoidance hole 111. A force is applied to the rotating shaft by the hydraulic drive component to drive the rotating shaft to move relative to the bearing toward the avoidance hole, and move out of the support frame through the avoidance hole, thereby disconnecting the rotating shaft from the bearing. The hydraulic drive component can apply a continuous and constant force to the rotating shaft, thereby enabling the rotating shaft to move stably and the rotating shaft is not easily damaged, thereby improving the maintenance effect of the axial flow fan.

[0040] The following describes embodiments of the present invention in conjunction with the accompanying drawings.

[0041] Reference Figure 1An embodiment of the present application provides a maintenance platform for an axial flow fan. The axial flow fan includes a housing, a rotating shaft, and a bearing, wherein the bearing connects the housing and the rotating shaft. The maintenance platform for the axial flow fan includes: a support frame 100 and a hydraulic drive component 200. The support frame 100 has an avoidance hole 111 and at least one accommodating groove 112. The accommodating groove 112 is used to accommodate a portion of the housing so that the rotating shaft corresponds to the avoidance hole 111. The hydraulic drive component 200 is disposed on the support frame 100. The hydraulic drive component 200 is used to drive the rotating shaft to move relative to the bearing so that the rotating shaft moves out of the support frame 100 through the avoidance hole 111.

[0042] The shape of the receiving groove 112 matches the shape of the partial housing. The partial housing is placed in the receiving groove 112 to secure the housing to the support frame 100. This prevents the housing and bearing from moving synchronously when the hydraulic drive element 200 drives the rotating shaft to move, thereby facilitating removal of the rotating shaft from the bearing.

[0043] For example, the rotating shaft is cylindrical, and the avoidance hole 111 is a circular hole. The size of the avoidance hole 111 can be adaptively set according to actual needs, so that the inner diameter of the avoidance hole 111 is larger than the diameter of the rotating shaft, so that the rotating shaft can be easily inserted into the avoidance hole 111. For example, the diameter of the avoidance hole 111 is 6 cm.

[0044] Specifically, the support frame 100 is first placed on a support surface, with the opening of the receiving slot 112 facing away from the support surface. A portion of the housing is then placed in the receiving slot, with the rotating shaft facing the avoidance hole 111. The hydraulic drive element 200 covers the side of the rotating shaft facing away from the avoidance hole 111. The hydraulic drive element 200 applies a constant force to the rotating shaft, causing it to move toward the avoidance hole 111 and out of the support frame 100 through the avoidance hole 111, thereby disconnecting the rotating shaft from the bearing.

[0045] The hydraulic drive unit 200 uses liquid to transmit power, rather than generating force directly through the collision of metal parts. This indirect method of transmitting power reduces friction and impact on the rotating shaft, thereby reducing wear and damage to the rotating shaft. Secondly, the liquid can effectively absorb and disperse the impact force, reducing the impact and vibration on the rotating shaft and reducing the possibility of fatigue damage to the rotating shaft. In addition, the working process of the hydraulic drive unit 200 is relatively stable and has high control accuracy. It can better control the magnitude and direction of force and reduce the possibility of accidental damage. Therefore, compared with a hammer strike, the hydraulic drive unit 200 driving the rotating shaft to move has higher durability and stability, and causes less damage to the rotating shaft.

[0046] Illustratively, the hydraulic driving component 200 is a hydraulic cylinder.

[0047] The maintenance platform for an axial flow fan provided in an embodiment of the present application includes a support frame 100 and a hydraulic drive member 200. The support frame 100 has an avoidance hole 111 and at least one receiving groove 112. The receiving groove 112 matches a portion of the housing so that the housing is fixed through the receiving groove 112, thereby fixing the housing to the support frame 100, preventing the housing and the bearing from moving, facilitating the movement of the rotating shaft relative to the bearing and disengaging the bearing, thereby improving the maintenance efficiency of the axial flow fan. At the same time, the rotating shaft can be aligned with the avoidance hole 111. The hydraulic drive member 200 applies a force to the rotating shaft to drive the rotating shaft to move relative to the bearing toward the avoidance hole 111 and move out of the support frame 100 through the avoidance hole 111, thereby disconnecting the rotating shaft from the bearing. The hydraulic drive member 200 can apply a continuous and constant force to the rotating shaft, thereby ensuring stable movement of the rotating shaft and preventing damage to the rotating shaft, thereby improving the maintenance efficiency of the axial flow fan.

[0048] In a specific implementation, the hydraulic drive member 200 includes a drive member body 210 and at least one control member 221. The control member 221 is arranged on the support frame 100. The control member 221 is electrically connected to the drive member body 210 to control the start and stop of the drive member body 210. The drive member body 210 is used to contact the rotating shaft to drive the rotating shaft to move relative to the bearing.

[0049] The control member 221 is a control button, and the driving member body 210 abuts against the end surface of the rotating shaft away from the avoidance hole 111 and drives the rotating shaft to move toward the avoidance hole 111 relative to the bearing.

[0050] Exemplarily, the control member 221 includes a start button and a stop button to control the start or stop of the driver body 210. The control member 221 also includes a push button to control the driver body 210 to move toward the avoidance hole 111.

[0051] Furthermore, the hydraulic drive unit 200 further includes a mounting plate 220, which is connected to one side of the support frame 100. The control units 221 are all disposed on the mounting plate 220, so that the operator can operate the control units 221. For example, the length and width of the mounting plate 220 are 16 cm and 1 cm, respectively.

[0052] In some embodiments, the control member 221 includes an adjustment knob, which is used to adjust the output parameters of the driver body 210 and thereby adjust the magnitude of the force applied by the driver body 210 to the rotating shaft.

[0053] In some embodiments, the maintenance platform for the axial flow fan provided in the embodiments of the present application also includes a mounting bracket 300, the mounting bracket 300 includes a first section 310 and a second section 320 arranged on one side of the first section 310, the first section 310 is connected to the support frame 100, and the second section 320 is connected to the hydraulic drive component 200.

[0054] The mounting bracket 300 is provided so that the hydraulic drive component 200 is located on one side of the support frame 100 and opposite to the avoidance hole 111 . At the same time, the structure of the hydraulic drive component 200 is relatively stable, thereby facilitating the hydraulic drive component 200 to drive the rotating shaft to move.

[0055] For example, the first section 310 and the second section 320 are perpendicular to each other, with the first section 310 arranged vertically. The height of the first section 310 can be adjusted based on actual needs, as long as the height of the first section 310 is greater than the axial length of the axial flow fan. The length of the second section 320 can be adjusted based on the relative position of the first section 310 and the avoidance hole 111, so that the hydraulic drive member 200 is opposite the avoidance hole 111. Specifically, the second section 320 is connected to the drive member body 210.

[0056] In some embodiments, the first section 310 is rotatably connected to the support frame 100. Rotation of the first section 310 relative to the support frame 100 drives the second section 320 to rotate relative to the support frame 100, thereby driving the hydraulic drive member 200 to rotate relative to the support frame 100, such that the hydraulic drive member 200 is positioned opposite the avoidance hole 111, or the hydraulic drive member 200 is positioned to one side of the avoidance hole 111. Before placing the axial flow fan on the support frame 100, the first section 310 is rotated relative to the support frame 100 to drive the hydraulic drive member 200 to rotate relative to the support frame 100 to one side of the avoidance hole 111, thereby facilitating placement of the axial flow fan on the support frame 100. After placement of the axial flow fan on the support frame 100, the first section 310 is rotated relative to the support frame 100 to rotate the hydraulic drive member 200 to face the avoidance hole 111, thereby aligning the hydraulic drive member 200 with the rotation axis, facilitating movement of the rotation axis driven by the hydraulic drive member 200.

[0057] In some embodiments, the first section 310 is rotatably connected to the second section 320, and the second section 320 rotates relative to the first section 310 to drive the hydraulic drive component 200 to move relative to the support frame 100, thereby making the hydraulic drive component 200 opposite to the avoidance hole 111, or located on one side of the avoidance hole 111.

[0058] In some embodiments, the first section 310 includes a telescopic member that controls the extension or retraction of the first section 310 to adjust the height of the first section 310. This allows the distance between the hydraulic drive member 200 and the support frame 100 to be adjusted via the second section 320, so that the height of the hydraulic drive member 200 matches the height of the rotating shaft. Before placing the axial flow fan on the support frame 100, the first section 310 is extended to move the hydraulic drive member 200 away from the support frame 100, increasing the distance between the hydraulic drive member 200 and the support frame 100 and facilitating placement of the axial flow fan on the support frame 100. After the axial flow fan is placed on the support frame 100, the first section 310 is retracted to move the hydraulic drive member 200 toward the support frame 100, thereby causing the hydraulic drive member 200 to abut against the rotating shaft and drive the rotating shaft toward the avoidance hole 111.

[0059] Furthermore, the control member 221 includes a telescopic control button, which is electrically connected to the telescopic member to control the telescopic member. Exemplarily, the telescopic control button includes an extension button and a reset button.

[0060] In some embodiments, the maintenance platform for the axial flow fan provided by the embodiments of the present application further includes at least one support base 500 , which connects the first section 310 and the support frame 100 .

[0061] The support base 500 is provided to support the first section 310 , thereby making the first section 310 more stable and reliable, and thus making the hydraulic drive component 200 more stable.

[0062] Exemplarily, the first section 310 is connected to the middle area of ​​the side of the support frame 100, and there are two support bases 500, which are respectively connected to opposite sides of the first section 310, and both support bases 500 are connected to the support frame 100. The height of the support base 500 is less than the height of the first section 310.

[0063] Reference Figure 1 and Figure 2 In some embodiments, the maintenance platform for the axial flow fan provided in the embodiments of the present application further includes a collecting member 400, which has a collecting chamber. The collecting member 400 is connected to the peripheral side of the avoidance hole 111 away from the hydraulic drive member 200 so that the collecting chamber is connected to the avoidance hole 111, and the collecting chamber is used to collect the rotating shaft moved out through the avoidance hole 111.

[0064] The rotating shaft is at least partially inserted into the collecting cavity through the avoidance hole 111 so as to collect the rotating shaft through the collecting cavity.

[0065] The length of the collection chamber is smaller than the length of the rotating shaft, so that when the rotating shaft is inserted into the collection chamber, part of the rotating shaft is located outside the collection chamber, making it easier for the operator to hold the rotating shaft and remove it from the collection chamber, thereby making it easier to remove the rotating shaft from the collection piece 400.

[0066] Specifically, the collecting member 400 is located between the support frame 100 and the supporting surface. The hydraulic driving member 200 drives the rotating shaft to move toward the supporting surface, so that the rotating shaft is partially inserted into the collecting member 400 through the avoidance hole 111. After the rotating shaft is disconnected from the bearing, the rotating shaft falls into the collecting member 400 and can be collected by the collecting member 400.

[0067] In a specific implementation, the collecting member 400 is tapered, and the large-diameter end of the collecting member 400 is connected to the peripheral side of the avoidance hole 111 .

[0068] The large-diameter end of the collector 400 is connected to the side of the avoidance hole 111 that faces the support surface, thereby connecting the collection chamber to the avoidance hole 111. The small-diameter end of the collector 400 can be closed or open. When the small-diameter end of the collector 400 is open, the area of ​​the small-diameter end of the collector 400 is smaller than the area of ​​the cross-section of the rotating shaft perpendicular to the axial direction, thereby preventing the rotating shaft from falling out through the small-diameter end of the collector 400.

[0069] It is understood that the shapes of the large diameter end and the small diameter end of the collecting member 400 can be adaptively set according to actual needs, and this embodiment does not limit this. For example, the shapes of the large diameter end and the small diameter end of the collecting member 400 can be circular or polygonal.

[0070] For example, the collecting member 400 may be connected to the support frame 100 in a fixed or detachable manner. For example, the collecting member 400 may be welded to the support frame 100 .

[0071] Furthermore, the collecting member 400 is detachably connected to the support frame 100 so that when the rotating shaft of different sizes is removed, the collecting member 400 of different sizes can be replaced to match the rotating shaft. For example, the collecting member 400 is threadedly connected or clamped to the support frame 100.

[0072] In some embodiments, the axis of the collecting member 400 is inclined relative to the vertical direction.

[0073] The axis of the collection member 400 is tilted toward the first side of the support frame 100. When the rotating shaft is inserted into the collection member 400, the portion of the rotating shaft outside the collection chamber is tilted toward the second side of the support plate 110, with the first side and the second side facing each other. At this point, a worker can stand on the second side of the support plate 110, so that the portion of the rotating shaft outside the collection chamber is tilted toward the worker, with one end of the rotating shaft close to the worker, making it easier for the worker to grasp the rotating shaft and remove it from the collection chamber more conveniently.

[0074] Furthermore, relative to the axis of the collecting member 400 being perpendicular to the support plate 110, the axis of the collecting member 400 is inclined relative to the vertical direction, so that the collecting member 400 can be set to a longer length, and thus when collecting a rotating shaft with a longer length, it is avoided that the rotating shaft is not completely disconnected from the bearing when it abuts against the bottom of the collecting member 400, resulting in the rotating shaft being unable to be completely disassembled.

[0075] For example, the axis of the collecting member 400 forms an angle with the vertical direction, and the angle is an acute angle. Further, the angle can be 10°-35°, and can be 10°, 15°, 20°, etc.

[0076] In a specific implementation, there are two accommodating grooves 112 , and the two accommodating grooves 112 are respectively located on both sides of the avoidance hole 111 .

[0077] The axial fan housing includes a housing body and two fixing plates, with the receiving slots 112 matching the sides of the fixing plates away from the housing body. When the axial fan is placed on the support frame 100, the two fixing plates are partially located in the two receiving slots 112 to secure the housing to the support frame 100.

[0078] Exemplarily, the length and width of the receiving groove 112 are 11 cm and 0.5 cm respectively, and the distance between two receiving grooves 112 is 20 cm.

[0079] In a specific implementation, the number of the accommodating groove 112 is one, and the accommodating groove 112 is an annular groove.

[0080] The avoidance hole 111 is located at the center of the accommodating groove 112 .

[0081] The housing of the axial flow fan includes a housing body and two annular plates. The housing body is a sleeve. The two annular plates are coaxially connected to the two ends of the housing body respectively. The accommodating grooves 112 match the annular plates.

[0082] In a specific implementation, the support frame 100 includes a support plate 110 and at least three support rods 120. The accommodating groove 112 and the avoidance hole 111 are both located on the support plate 110. The support rods 120 are all connected to the side of the support plate 110 away from the accommodating groove 112, and each support rod 120 is arranged at intervals.

[0083] The avoidance hole 111 is a through hole, and is located in the middle area of ​​the support plate 110 .

[0084] It is understood that the shape of the support plate 110 can be a cylinder, a polygonal prism, or other irregular shape, and this embodiment does not limit this. For example, the support plate 110 is a rectangular parallelepiped, and the number of support rods 120 is four, and the four support rods 120 are connected to the four corners of the support plate 110 respectively. The support plate 110 is 100 cm long, 60 cm wide, and 1 cm high.

[0085] The shape and length of the support rod 120 can be adaptively set according to actual needs to facilitate operation by the operator, and this embodiment does not limit this. For example, the support rod 120 is a rectangular parallelepiped, the length and width of the support rod 120 are both 5 cm, and the height of the support rod 120 is 85 cm.

[0086] In some embodiments, one side of the mounting plate 220 is connected to the support plate 110 , and the other side of the mounting plate 220 is connected to the support rod 120 .

[0087] In some embodiments, the collecting member 400 is connected to the side of the support plate 110 facing away from the hydraulic drive member 200. The height of the collecting member 400 is less than the length of the support rod 120 to avoid interference between the collecting member 400 and the support surface when the support frame is placed on the support surface.

[0088] In some embodiments, a roller is provided at one end of the support rod 120 away from the support plate 110. The roller is connected to the end surface of the support rod 120 away from the support plate 110, and the roller contacts the support surface, so that the roller rolls relative to the support surface to drive the support rod 120 to move relative to the support surface, thereby driving the support plate 110 to move relative to the support surface, thereby making it easier and more convenient to adjust the position of the support frame 100 relative to the support surface.

[0089] Exemplarily, at least two rollers are provided with brakes. After the support frame 100 is moved to a desired position, the brakes are operated to prevent the rollers from rolling relative to the support rods 120, thereby preventing the support frame 100 from moving relative to the support surface, thereby fixing the support frame 100 at the current position.

[0090] Specifically, after the support frame 100 is moved to a desired position and fixed, the axial flow fan is placed on the support frame 100 and the rotating shaft is disassembled to prevent the support frame 100 from moving relative to the supporting surface when the rotating shaft is disassembled.
