Description

Technical Field

[0001] The invention relates to the technical field of fan assembly, and in particular to a fan impeller disassembly and assembly tool. Background Art

[0002] One of the main components of a fan is the impeller. The removal and installation of the impeller is an important part of the maintenance and overhaul of the fan. The traditional method of removing and installing the fan impeller is usually done manually, which is not only inefficient, but also difficult to remove manually due to the heavy weight of the fan impeller. In addition, due to the long-term use of the fan, the air humidity at the impeller is high, which can easily lead to a large amount of rust on the impeller and the shaft, increasing the friction between the impeller and the shaft, making the removal operation more difficult. Summary of the invention

[0003] In view of this, an object of the present invention is to provide a fan impeller disassembly and assembly tool and assembly, which is convenient for disassembly and has high disassembly efficiency, saving manpower and material resources.

[0005] In one embodiment, the top opening component includes a connecting member and a power member, the power member is connected to the connecting plate through the connecting member, the power member is assembled on the assembly frame, and when the power member is in working state, it abuts against the rotating shaft of the fan impeller and exerts its own force on the fan impeller through the connecting plate.

[0006] In one embodiment, the connecting member includes a screw segment and a hook segment, the hook segment is connected to the screw segment, and the screw segment is threadedly connected to the power member. Correspondingly, a hook hole is provided on the connecting plate, and the hook segment passes through the hook hole and is tightly attached to the connecting plate in a working state to achieve connection with the connecting plate.

[0007] In one embodiment, the assembly frame includes at least two support seats and an adjusting screw rod, the two support seats are connected by the adjusting screw rod, and the push-opening member is assembled on the support seats.

[0018] Embodiment 1

[0019] See also Figure 1 The fan impeller disassembly and assembly tool provided by the present invention includes a connecting plate 1, a top opening component 2 and an assembly frame 4. The connecting plate 1 is connected to the top opening component 2 and is used to be assembled on the fan impeller 301. The top opening component 2 is assembled on the assembly frame 4 and is used to abut against the rotating shaft 302 of the fan impeller 301 in a working state and exert its own force on the fan impeller 301 through the connecting plate 1.

[0020] It can be known that the manufacturer has reserved a through hole on the fan impeller 301 in this embodiment, and a bolt hole can be set on the connecting plate 1. The locking bolt passes through the through hole and the bolt hole of the connecting plate 1 to realize the connection and fixation between the connecting plate 1 and the fan impeller 301. The connecting plate 1 can be elliptical, and its shape is to adapt to the fan impeller 301. Before disassembly, the fan impeller 301 is heated with a baking gun until the temperature of the fan impeller 301 is not less than 220°C. When the top opening member 2 is in the working state, it will provide an external force, which is a top opening force in the direction away from the rotating shaft 302. The external force acts on the fan impeller 301 through the connecting plate 1. The assembly frame 4 can prevent the top opening member 2 from being displaced relative to the fixed position of the assembly frame 4 during operation. In addition to disassembling the fan impeller 301, the fan impeller 301 can also be installed.

[0021] See also Figure 1In some embodiments, the top opening member 2 includes a connecting member 202 and a power member 201. The power member 201 is connected to the connecting plate 1 through the connecting member 202. The power member 201 is assembled on the assembly frame 4. When the power member 201 is in working state, it abuts against the rotating shaft 302 assembled with the fan impeller 301, and exerts its own force on the fan impeller 301 through the connecting plate 1.

[0022] It can be understood that the connecting member 202 can be detachably connected to the connecting plate 1, and a through hole is provided on the connecting plate 1. The power member 201 can be a hydraulic jack, and the piston rod of the hydraulic jack will move and exert force on the rotating shaft 302. A lifting lug can be provided on the hydraulic jack to facilitate the lifting of the hydraulic jack, thereby realizing the removal of the fan impeller 301 from the rotating shaft 302. The top opening mechanism 2 has a simple structure and is easy to use.

[0023] See also Figure 1 and Figure 2 In some embodiments, the connecting member 202 includes a screw segment and a hook segment, the hook segment is connected to the screw segment, and the screw segment is threadedly connected to the power member 201. Correspondingly, a hook hole is provided on the connecting plate 1, and the hook segment passes through the hook hole and is tightly attached to the connecting plate 1 in the working state to achieve connection with the connecting plate 1.

[0024] It can be understood that a mounting seat can be provided on the hydraulic jack, and a connecting hole is provided on the mounting seat. The screw segment passes through the connecting hole and is connected to two nuts, which are respectively located on both sides of the mounting seat, thereby realizing the connection and fixation between the screw segment and the hydraulic jack. The hook segment can be located in the hook hole. In the working state, the hook segment interferes with the connecting plate 1, thereby enabling convenient disassembly and fixation of the connecting piece 202 and the connecting plate 1.

[0025] Please continue reading Figure 1 In some embodiments, the assembly frame 4 includes at least two support seats and an adjusting screw rod, the two support seats are connected by the adjusting screw rod, and the top opening member is assembled on the support seats.

[0026] It can be understood that the support seat can be an I-beam, an elliptical disk can be set on the I-beam, the hydraulic jack can be bolted and hung on the elliptical disk, and the adjustment screw between the two I-beams can adjust the distance between the two I-beams, so that the fan impeller 301 can be located between the two I-beams during disassembly work. Adjustable height support legs can also be set under the I-beam to adapt to fans 3 of different heights.

[0027] Embodiment 2

[0028] See also Figure 1The present embodiment provides a fan impeller disassembly and assembly tool assembly, including the above-mentioned fan impeller disassembly and assembly tool assembly, and also includes a fan impeller 301 and a rotating shaft 302. The fan impeller 301 is assembled on the rotating shaft 302, and the connecting plate 1 is assembled on the fan impeller 301. In the working state, the top opening member 2 abuts against the rotating shaft 302 and applies its own force to the fan impeller 301 through the connecting plate 1.

[0029] It is understandable that the fan impeller 301 can be tightly clamped on the rotating shaft 302 and then locked by a locking member. When disassembling, the locking member is removed and then disassembly is performed using a disassembly tool.

[0030] From the above description, it can be known that the fan impeller disassembly and assembly provided by the present invention provides power through the top opening component 2 and acts on the rotating shaft 302. The connecting plate 1 drives the fan impeller 301 to break away from the fixed position on the rotating shaft 302 under the action of external force, thereby disassembling the fan impeller 301. The disassembly is convenient and efficient, saving manpower and material resources.

[0031] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
