Description

Technical Field

[0001] The present application relates to the technical field of axial flow fan disassembly and assembly, and in particular to a quick disassembly and assembly device for an axial flow fan impeller. Background Art

[0002] The counter-rotating fan is a special axial flow fan, which is mainly used in the construction of tunnels such as highways, railways and underground projects or in places where forced ventilation is required. The traditional counter-rotating fan for mining realizes the rotation of the two-stage impeller through the power applied by the motor. In the actual operation process, the motor is arranged in the axial direction of the fan, which will increase the axial volume of the fan, and it is not convenient to arrange it in small and narrow places in the excavation tunnel. The traditional counter-rotating fan for mining has the following problems: the axial volume of the traditional counter-rotating fan for mining is large, which is not convenient for arrangement in small tunnels; the motor is in the axial center of the fan, which occupies the effective ventilation space of the wind tube, resulting in large ventilation resistance, low fan efficiency, and the motor will burn due to poor heat dissipation.

[0003] In the event of partial axial flow fan failure, the speed of the axial flow fan will be set relatively high to ensure that the remaining axial flow fans can reach the required air volume for heat dissipation. If the axial flow fan keeps running at a high speed, the impeller of the axial flow fan will be damaged, and the impeller will fall off or deform. A damaged axial flow fan will produce a lot of noise, that is, the dynamic balance will fail. Axial flow fans with dynamic balance failure need to be inspected and replaced by equipment maintenance personnel.

[0004] In tunnels, mines or large factories, ventilation ducts are usually required for ventilation. The space in the air duct is narrow and long, and maintenance personnel need to disassemble the axial flow fan part of the air duct in sections.

[0049] Embodiment 1

[0050] In tunnels, mines or large factories, ventilation systems are usually required for ventilation.

[0051] Industrial axial flow fans are equipped with a wind tube and a fan, and the fan is installed along the axial direction of the wind tube. The wheel group of the fan drives the motor to drive the impeller to rotate, and the air blown out by the impeller forms an air duct along the wind tube. External air is blown into the ventilation place through the air duct.

[0052] In places such as tunnels, the length of the wind tube needs to be matched according to the depth of the tunnel, and the wind tube extends from the outside of the tunnel to the inside of the tunnel. Therefore, the length of the wind tube is generally 20-30 meters and the diameter is about 1 meter.

[0053] Since the fan duct is too long, when the fan fails, it is troublesome to disassemble the fan, and the entire module including the fan needs to be disassembled for repair. When the fan impeller fails, it is actually only necessary to replace the impeller without disassembling the entire fan.

[0054] The present invention provides a quick disassembly and assembly machine for an axial flow fan impeller, which can be used to disassemble and assemble the impeller in a wind tube.

[0055] like Figure 1 The device for quickly disassembling and assembling an axial flow fan impeller shown comprises: a pipeline creeping wheel assembly 1, a device mounting shell 2 and an impeller disassembling and assembling mechanism 3.

[0056] in, Figure 2 for Figure 1 A partial enlarged view of area A in FIG. 1 , area A is the impeller disassembly and assembly mechanism 3 . Figure 3 This is a partial enlarged view of area B, where area B is the pipeline crawling wheel set 1. Figure 4 Rear view of the mounting case for the unit.

[0057] Specifically, Figure 4 As shown, the device installation shell 2 is provided with a main housing 21 and a support frame. The support frame is provided with at least three support shafts 221 around the cross section of the air duct, and the support shafts 221 are evenly distributed; one end of the support shaft 221 facing the surroundings is connected to the pipeline crawling wheel set 1, and the other end is fixed to the outer wall of the main housing 21.

[0058] Further, such as Figure 2 As shown, the impeller disassembly and assembly mechanism 3 is installed inside the main housing 21, and the impeller disassembly and assembly mechanism 3 is provided with a drill chuck 31 facing the impeller bolts, and the drill chuck 31 can rotate and disassemble the impeller bolts.

[0059] The duct crawling wheel set 1 abuts against the inner wall of the air duct and is used to drive the device to move along the air duct.

[0060] In the embodiment of the present application, the device is placed in the air duct, and the three duct crawling wheel groups 1 abut against the inner wall of the air duct in three directions respectively. The duct crawling wheel group 1 moves along the air duct toward the impeller to be disassembled. At the same time, the drill chuck 31 of the impeller disassembly and assembly mechanism 3 is aligned with the impeller bolt on the axis of the air duct. When the drill chuck 31 abuts against the impeller bolt, the drill chuck 31 clamps the impeller bolt, and then the impeller disassembly and assembly mechanism 3 rotates the drill chuck 31 to disassemble the impeller bolt.

[0061] Further, such as Figure 3 As shown, the pipeline crawling wheel set 1 includes: a rolling wheel 11 installed on a wheel set bracket 10, a wheel set driving motor 12 and a rotating component 13.

[0062] Specifically, the wheel set driving motor 12 and the rolling wheel 11 are connected through a shaft hole; the rotating component 13 is arranged between the rolling wheel 11 and the support shaft 221, and the rotating component 13 is used to adjust the angle of the rolling wheel 11.

[0063] In the embodiment of the present application, the wheel drive motor 12 is connected to the shaft hole on the rotor and the rolling wheel 11, and the wheel drive motor 12 drives the rolling wheel 11 to rotate, thereby moving the device on the air duct.

[0064] Further, such as Figure 2 It can be seen that the impeller disassembly and assembly mechanism 3 is also provided with a drill chuck transmission mechanism; the drill chuck 31 is driven by the drill chuck transmission mechanism, and the drill chuck 31 faces the impeller screw of the axial flow fan, and is used to remove the impeller screw.

[0065] In the embodiment of the present application, when the device is removing the impeller bolts, the drill chuck 31 needs to clamp the impeller to be removed. Figure 6 The impeller bolt shown is then driven to rotate the drill chuck 31 around the axis of the impeller bolt.

[0066] In a driving mode of the drill chuck 31 , the drill chuck transmission mechanism is a separately provided drill chuck driving motor, and the drill chuck driving motor drives the drill chuck 31 to rotate around an axis.

[0067] In another driving method of the drill chuck 31, the main shell 21 of the device mounting shell 2 is also provided with a first gear 211, and the sleeve 311 is provided with a second gear 312; the tooth line direction of the first gear 211 and the second gear 312 is circumferentially around the air duct; the first gear 211 and the second gear 312 are meshed for transmission.

[0068] In the toothed transmission structure, the drill chuck transmission mechanism is a toothed transmission mechanism formed by a first gear 211 on the drill chuck 31 and a second gear 312 on the device mounting shell 2, and the drill chuck 31 and the device mounting shell 2 are engaged with each other through gears.

[0069] Therefore, in order to drive the drill chuck through the first gear, as Figure 3 The pipeline crawling wheel assembly 1 shown is also provided with a rotating component 13, and the rotating component 13 drives the rolling wheel 11 to flip so that the axial direction of the rolling wheel 11 is parallel to the axial direction of the air duct. Figure 5 As shown, when the wheel assembly driving motor 12 is working, the rolling wheel 11 rotates around the circumference of the air duct, so that the impeller disassembly mechanism rotates around the axis of the air duct, thereby driving the drill chuck 31 to tighten the impeller bolt.

[0070] As a comparison, Figure 4 and Figure 5 They are schematic diagrams of the states of the scroll wheel 11 before and after it is flipped.

[0071] In the embodiment of the present application, the toothed transmission mechanism can reduce the hardware cost compared with the drill chuck drive motor.

[0072] Furthermore, the drill chuck 31 is provided with a sleeve 311 and a clamp 313. The sleeve 311 is provided with a clamp accommodating cavity along the axis of the air duct, and the clamp 313 is sleeved in the clamp accommodating cavity, and the clamp 313 faces the impeller bolt; the sleeve 311 is used to adjust the opening and closing angle of the clamp 313.

[0073] It is understandable that, in the mechanical structure principle of the drill chuck, when the sleeve 311 rotates in one direction, the opening and closing angle of the clamp 313 will be changed, so that the clamp 313 can adapt to impeller bolts of different calibers.

[0074] When the drill chuck transmission mechanism is a toothed transmission mechanism, after the drill chuck 31 clamps the impeller bolt, the first gear 211 and the second gear 312 are stuck because the impeller bolt blocks the clamp 313 from tightening. The wheel drive motor 12 rotates again to drive the entire device to rotate, thereby tightening the impeller bolt.

[0075] In order to allow the device to adapt to air ducts of different diameters, a support spring 23 is further arranged between the support shaft 221 and the outer wall of the device mounting shell 2, and the supporting end of the support spring 23 abuts against the support shaft 221, and the fixed end of the support spring 23 is fixed to the outer wall of the device mounting shell 2.

[0076] In the embodiment of the present application, under the action of the support spring 23, the three support shafts 221 of the support clamp are always opened to the surroundings, so that the rolling wheel 11 is tightly pressed against the inner wall of the air duct.

[0077] Furthermore, the drill chuck 31 is a magnetic component, which is used to magnetically fix the disassembled impeller and take it out of the air duct.

[0078] The quick disassembly and assembly device shown in the embodiment of the present application is controlled by a remote controller, or operates autonomously through an automated controller.

[0079] Embodiment 2

[0080] Because the axial flow fan keeps running at a high speed in dusty places, the impeller of the axial flow fan will be damaged, and the impeller will fall off or deform. The damaged axial flow fan will produce a lot of noise. In other words, the impeller of the axial flow fan will fail to balance dynamically.

[0081] Before replacing the impeller of an axial flow fan, it is necessary to perform a dynamic balance test on the impeller. Since the air duct is narrow and long, it is not easy for maintenance personnel to perform the test. Therefore, based on the quick disassembly and assembly device of embodiment 1, the embodiment of the present application also provides a quick disassembly and assembly device with an impeller dynamic balance detection function.

[0082] In an embodiment of the present application, the quick disassembly and assembly device for an axial flow fan impeller also includes an impeller detection device.

[0083] Specifically, the impeller detection device is provided with an image acquisition module and a processing module.

[0084] The image acquisition module is mounted on the device mounting shell 2, and takes pictures in a direction perpendicular to the radial direction of the impeller of the axial flow fan; the image acquisition module is used to acquire the impeller trajectory image and send it to the processing module.

[0085] In an embodiment of the present application, the processing module is used to process the impeller trajectory image and perform the following steps:

[0086] S1, obtaining the impeller trajectory image acquired by the image acquisition module;

[0087] S2, performing binarization processing on the impeller trajectory image to obtain a black and white image of the impeller trajectory image;

[0088] S3, determining the impeller light-emitting trajectory according to the pixel matrix of the impeller trajectory image, wherein the impeller light-emitting trajectory is the circular area swept by the impeller when it rotates;

[0089] S4. Determine the vibration amplitude of the impeller according to the light emitting trajectory of the impeller. If the light emitting trajectory of the impeller does not match the preset trajectory, it is determined that the vibration amplitude of the impeller is too large. Otherwise, it is determined that the vibration amplitude of the impeller is normal.

[0090] Furthermore, step S1 specifically includes:

[0091] S11, acquiring an image of the axial flow fan taken by the image acquisition module;

[0092] S12, converting the axial flow fan image into a grayscale image, and cropping the axial flow fan image according to the number of the axial flow fans to obtain N impeller trajectory images.

[0093] Furthermore, step S4 specifically includes:

[0094] S41, determining the maximum diameter between two points of the impeller light-emitting trajectory according to the pixel coordinates of the impeller trajectory image;

[0095] S42. Determine whether the vibration amplitude of the impeller is greater than a preset ring width threshold according to the maximum diameter between two points of the impeller's luminous trajectory. If so, send abnormal vibration amplitude information; if not, send normal vibration amplitude information.

[0096] Since the impeller of the axial fan is painted, its color is brighter, and the rotating image of the impeller is displayed as a ring. The processing module converts the impeller trajectory image into a pixel matrix image. In the pixel matrix image, the luminous trajectory of the impeller, that is, the area swept by the impeller, appears in a ring shape. The pixel element value of the luminous trajectory of the impeller in the pixel matrix image is assigned as 1.

[0097] In the embodiment of the present application, an image acquisition device is set on the device to capture the impeller image of the axial flow fan, and the impeller image is threshold processed to obtain the impeller trajectory image. The maximum diameter between the pixel points of the impeller trajectory image is calculated. If the impeller vibrates abnormally, the maximum diameter is greater than the preset ring width threshold, and if the impeller vibrates normally, the maximum diameter is less than the preset ring width threshold.

[0098] Regarding the device in the above embodiment, the specific way in which each module performs the operation has been described in detail in the embodiment of the method, and will not be elaborated here.
