They are one of the core components of industrial fans and motors. Impellers and gears are mostly installed close to other components inside industrial fans and motors, and their connection with the main shaft of industrial fans and motors is tight due to interference or long service life. It takes a lot of pulling force to remove them from the main shaft. Under normal conditions of on-site maintenance and repair, it is difficult to disassemble large impellers and gears, and the disassembly time is long. Large pullers are generally used for the disassembly of impellers and gears, which are relatively bulky, costly, and generally ineffective. The angle of effort is large when using them, which is time-consuming and laborious to use. In addition, during disassembly, the claws of the puller and the impeller and gear are easy to slip off, which is inconvenient to use and can easily cause safety hazards such as collisions and smashing. At the same time, the claws of the puller often clamp the thinner edges of the impeller and gear, causing the impeller and gear to no longer be used, resulting in losses. Utility Model Content

[0024] The specific implementation methods disclosed in the present utility model are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation methods described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.
[0025] like Figure 1 , Figure 2 and Figure 3 The figure shows an exemplary embodiment of the utility model disclosed in the disclosure. The utility model industrial fan impeller gear disassembly device comprises a screw 20, a plate body 10, and a connecting bolt 30. A thread hole 11 is provided at the central position of the plate body 10, and the thread hole 11 is provided with an internal thread. The screw 20 is provided with an external thread on the rod body. The screw 20 passes through the thread hole 11 and is threadedly connected with the plate body 10. A head 21 is installed at the bottom of the screw 20, and a torque cap 22 is fixedly installed at the top of the screw 20. A plurality of grooves 12 for accommodating the connecting bolts 30 are provided on the plate body 10, and the connecting bolts 30 are inserted into the grooves 12. The bolt cap 31 of the connecting bolt 30 and the torque cap 22 are located on the same side of the plate body 10.
[0026] Specifically, Figure 1 , Figure 2 and Figure 3As shown, in the exemplary embodiment disclosed in the utility model, the industrial fan impeller gear disassembly device includes a gasket 40, and the connecting bolt 30 passes through the gasket 40 and is inserted into the groove 12. The diameter of the gasket 40 is greater than the width of the groove 12, and the gasket 40 and the bolt cap 31 of the connecting bolt 30 are on the same side of the plate body 10. The plate body 10 is a circular disk body, and the groove 12 is opened along the outer circumference of the disk body toward the center of the disk body, and the end of the groove 12 close to the center of the disk body is kept at a certain distance from the center of the disk body.
[0027] The utility model industrial fan impeller gear disassembly device utilizes the bolt holes commonly present on the impeller and gear bodies to be disassembled, and extends the connecting bolt 30 into the bolt hole, so that the connecting bolt 30 is threadedly connected with the impeller and gear, and the other end of the connecting bolt 30 is inserted into the groove 12 of the plate body 10 and fixed to the plate body 10. A thread hole 11 is opened at the central position of the plate body 10, and the thread hole 11 is provided with an internal thread. The outer surface of the screw rod 20 is provided with an external thread. One end of the screw rod 20 passes through the thread hole 11 to support the main shaft of the industrial fan and motor connected with the impeller and gear. The other end of the screw rod 20 is provided with a torque cap 22. By turning the torque cap 22 with the help of a wrench or a motor, the screw rod 20 is pushed out toward the main shaft, thereby removing the impeller and gear from the main shaft. The utility model industrial fan impeller gear disassembly device is connected and fixed with the impeller and gear thread by the connecting bolt 30. It is not easy to slip off the impeller and gear during the whole disassembly process. At the same time, it is not necessary to clamp the thin edge of the impeller and gear, and the impeller and gear will not be damaged. The plate body 10 of the utility model industrial fan impeller gear disassembly device is circular, and the groove 12 is opened along the outer circumference of the plate body to the center of the plate body. Compared with opening a small hole on the plate body 10 to allow the connecting thread to pass through, the design of the groove 12 can adapt to a wider range. The hole spacing between the bolt holes on the impeller and gear is not fixed, and their sizes are different. If a small hole is opened on the plate body 10, it cannot adapt to a variety of hole spacings, and its adaptability range is small. The design of the groove 12 can linearly adjust the distance between the bolt cap 31 of the connecting bolt 30 on the plate body 10 according to the hole spacing of the bolt holes on the impeller and gear, so that the connecting bolt 30 is vertically connected to the bolt hole on the impeller and gear and fixed to the plate body 10. One end of the groove 12 close to the center of the disk body is kept at a certain distance from the center of the disk body, which can avoid collision with the connecting bolt 30 when the torque cap 22 of the screw 20 is rotated. In order to allow the industrial fan impeller gear disassembly device to adapt to the bolt holes of different sizes on the impeller and gear, the width range of the groove 12 can be appropriately expanded so that the connecting bolts 30 of different diameters can be inserted into the groove 12. The connecting bolt 30 first passes through the gasket 40, so that the gasket 40 and the bolt cap 31 of the connecting bolt 30 are on the same side of the plate body 10, and the diameter of the gasket 40 is greater than the width of the groove 12. In this way, the connecting bolt 30 with a relatively small diameter can also be inserted into the groove 12. On the other hand, the gasket 40 can also make the force surface between the connecting bolt 30 and the plate body 10 larger and more uniform.
[0028] For example, Figure 1 , Figure 6 As shown, the plug 21 is detachably connected to the bottom of the screw rod 20 .
[0029] Specifically, Figure 1 An exemplary embodiment of the present invention is shown in the following figure: Figure 1 As shown, the plug 21 is a cone, and the circular end of the cone is detachably connected to the bottom of the screw rod 20. Figure 6 Another exemplary embodiment of the industrial fan impeller gear removal device head 21 of the utility model is shown. Figure 6 As shown, the plug 21 is a cylinder, one end of which is concave to form a cone, and the other end of the cylinder is detachably connected to the bottom of the screw rod 20.
[0030] The plug 21 and the bottom of the screw 20 are designed to be detachably connected, such as a threaded connection or an interference fastening connection. When in use, different plugs 21 can be installed to the bottom of the screw 20 according to the shape of the industrial fan connected to the impeller to be disassembled, the gear, and the end of the motor main shaft. When the main shaft has an axial hole, a conical plug 21 can be installed to the bottom of the screw 20, and the conical tip of the plug 21 can extend into the axial hole. When the end of the main shaft protrudes outward, a cylindrical plug 21 is installed, and the concave end of the cylindrical plug 21 supports the outward protruding part of the end of the main shaft. According to the different shapes of the ends of the industrial fan and the motor main shaft, the corresponding plug 21 is installed, so that the screw 20 is more tightly connected to the main shaft, and the torque cap 22 at the top of the screw 20 is turned, and the screw 20 is pushed toward the main shaft. At this time, the screw 20 is firmly connected to the main shaft, and there will be no top deviation. The force-bearing surface of the bottom of the screw 20 and the end of the main shaft is more uniform, and it is easier to remove the impeller and the gear from the main shaft.
[0031] For example, Figure 1 , Figure 4 , Figure 5 As shown, the number of the grooves 12 is 2-4.
[0032] Specifically, Figure 1 An exemplary embodiment of the present invention is shown in the following figure: Figure 1 As shown, there are two grooves 12 , which are located on the same horizontal line and on both sides of the screw rod 20 with the screw rod 20 as the axis of symmetry. Figure 4 Another disclosed exemplary embodiment of the industrial fan impeller gear disassembly device of the utility model is shown, as Figure 4 As shown, there are three grooves 12, two of which are on the same horizontal line and are located on both sides of the screw rod 20 with the screw rod 20 as the symmetry axis, and the other groove 12 is perpendicular to the horizontal line. Figure 5Another disclosed exemplary embodiment of the industrial fan impeller gear disassembly device of the utility model is shown, as Figure 5 As shown, there are four grooves 12 , and every two grooves 12 are on the same horizontal line and are located on both sides of the screw rod 20 with the screw rod 20 as the axis of symmetry. Every two grooves 12 on the same horizontal line are perpendicular to the other two grooves 12 .
[0033] One end of the connecting bolt 30 is threadedly connected to the impeller and the gear, and the bolt cap 31 at the other end is inserted into the groove 12 of the plate body 10. When the torque cap 22 on the screw rod 20 is turned, the screw rod 20 pushes toward the main shaft, and the plate body 10 moves along the screw rod 20 in the direction away from the main shaft, and at the same time drives the connecting bolt 30 and the impeller gear to move in the same direction. When a certain distance is reached, the impeller and the gear are removed from the main shaft. The groove 12 is opened along the outer circumference of the disk body toward the center of the disk body and is symmetrically arranged vertically on the plate body 10. When the plate body 10 drives the connecting bolt 30 and the impeller gear to move, the force applied to them is uniform, and there will be no deflection during the movement, and the impeller and the gear will move a larger distance on one side and a smaller distance on the other side, which is not easy to damage the impeller, the gear or the main shaft.
[0034] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.
[0035] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.
[0036] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
