Description

Technical Field

[0001] This utility model relates to the field of impeller fan technology, and more specifically, to a tool for quickly disassembling the impeller of a direct-drive impeller fan. Background Technology

[0002] A direct-drive impeller fan is a fan design in which the impeller is directly mounted on the shaft of the electric motor, rather than being driven by a belt or other transmission mechanism. This design simplifies the structure and improves efficiency, and therefore has been widely used in HVAC systems, industrial ventilation, air purification, and cooling systems.

[0003] However, direct-drive fans also present some challenges in maintenance and repair. Due to their compact design, the clearance between the motor and impeller is small, which complicates operation. Furthermore, because the impeller is not securely fixed, traditional disassembly tools such as shaft pullers are ineffective in applying force, making it very difficult to remove the impeller from the shaft. This difficulty in disassembly can prolong maintenance time, especially when the impeller is damaged and needs replacement, thus affecting the normal operation of the fan. Therefore, there is an urgent need to design a tool for quickly disassembling the impeller of a direct-drive impeller fan.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a tool for quick disassembly of the impeller of a direct-drive impeller fan, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0008] Furthermore, in order to effectively clamp impellers of different sizes on one side, improve the stability of impeller clamping, and ensure that the cylinder can effectively apply force to the impeller, making the subsequent separation process of the impeller and the fan smoother and more efficient, the clamping mechanism includes a cylinder set on one side of the support plate. The output end of the cylinder is equipped with a fixed rod. One end of the fixed rod is provided with an external thread I. A rotating part is provided on the outside of the external thread I. A rotating rod is symmetrically arranged on the outside of the top of the rotating part. A fixed part I is provided on the outside of the bottom of the rotating part.

The outer side of the sliding ring has an annular groove that cooperates with fixed parts I. Fixed parts II include a fixed ring set on the outside of the fixed rod. Several support blocks I that cooperate with the connecting plates are set on the outside of the fixed ring.

[0009] Furthermore, in order to achieve the lifting and adjustment of the support plate, effectively adapt to fans of different sizes, provide stable support for the fans, and thus lay a solid foundation for the smooth separation of the fan impeller, a U-shaped groove is opened on the top of one side of the snap-fit ​​plate, and a sliding groove that cooperates with the support plate is symmetrically opened on the bottom of one side of the snap-fit ​​plate; a protrusion that cooperates with the sliding groove is symmetrically arranged on one side of the support plate; the lifting mechanism includes a motor located at the top of the bottom of the housing, a rotating shaft is provided at the output end of the motor, and support blocks two that cooperate with the housing are symmetrically arranged at both ends of the rotating shaft. Both ends of the rotating shaft are provided with external threads two, and the thread directions of the external threads two at both ends of the rotating shaft are opposite. Sliding blocks are symmetrically arranged at both ends of the external threads two. A rotating rod one is connected to the outside of one set of sliding blocks, and a rotating rod two that cooperates with another set of sliding blocks is connected to the bottom end of the rotating rod one. Support blocks three that cooperate with the support plate are symmetrically arranged on the outside of the rotating rod one.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1) With the combined action of the clamping mechanism, the snap-fit ​​plate, the lifting mechanism and the support plate, this utility model can effectively clamp and support direct-drive impeller fans of different sizes, ensuring that the impeller fans can be effectively forceped and improving the efficiency of impeller and fan separation.

With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0024] According to an embodiment of the present invention, a tool for quickly disassembling the impeller of a direct-drive impeller fan is provided.

[0025] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-6 As shown, the quick-disassembly impeller tool for a direct-drive impeller fan according to an embodiment of the present invention includes a support side plate 1, a clamping mechanism 2 is provided on one side of the support side plate 1, a plurality of connecting columns 3 are provided on the other side of the support side plate 1, a snap-fit ​​plate 4 is provided on one side of the plurality of connecting columns 3, a housing 5 is provided at the bottom of one side of the snap-fit ​​plate 4, a lifting mechanism 6 is provided inside the housing 5, and a support plate 7 that cooperates with the snap-fit ​​plate 4 is provided at the top of the lifting mechanism 6.

[0026] With the help of the above technical solutions, this utility model, through the combined action of the clamping mechanism 2, the snap-fit ​​plate 4, the lifting mechanism 6, and the support plate 7, can effectively clamp and support direct-drive impeller fans of different sizes, ensuring that effective force can be applied to the impeller fans and improving the efficiency of impeller-fan separation. Under the action of the clamping mechanism 2, one side of impellers of different sizes can be effectively clamped, improving the stability of impeller clamping and ensuring that the cylinder 201 can effectively apply force to the impeller, making the subsequent impeller-fan separation process smoother and more efficient. With the combined action of the snap-fit ​​plate 4, the support plate 7, and the lifting mechanism 6, the lifting and adjusting of the support plate 7 can be realized, effectively adapting to fans of different sizes, providing stable support for the fans, and thus laying a solid foundation for the smooth separation of the fan impeller.

[0027] In one embodiment, the clamping mechanism 2 includes a cylinder 201 disposed on one side of the support side plate 1. A fixing rod 202 is disposed at the output end of the cylinder 201. An external thread 203 is disposed on the outer side of one end of the fixing rod 202. A rotating member 204 is disposed on the outer side of the external thread 203. A rotating rod 205 is symmetrically disposed on the outer side of the top end of the rotating member 204. A fixing member 206 is disposed on the outer side of the bottom end of the rotating member 204. Several fixing members 207 are disposed on the outer side of the fixing rod 202 and on one side of the external thread 203. The fixing members 206 and 207 have the same structure. Several connecting rods are disposed on the outer side of both fixing members 206 and 207. The connecting plate 208 has a clamping plate 209 on one side; the rotating component 204 includes a sliding ring 2041 that is disposed on the outside of the external thread 203 and cooperates with the rotating rod 205. The outer side of the sliding ring 2041 has an annular groove 2042 that cooperates with the fixing component 206; the fixing component 207 includes a fixing ring 2071 disposed on the outside of the fixing rod 202. The outer side of the fixing ring 2071 has several support blocks 2072 that cooperate with the connecting plate 208, which can effectively clamp one side of impellers of different sizes, improve the stability of impeller clamping, ensure that the cylinder 201 can effectively apply force to the impeller, and make the subsequent separation process of the impeller and the fan smoother and more efficient.

[0028] The working principle of clamping mechanism 2 is as follows: In the initial state, the operator adjusts the position of the impeller. Under the action of the external controller, the cylinder 201 is controlled and started. Under the action of the output shaft of cylinder 201, the fixed rod 202 is driven to the fan position. Then, the operator applies a clockwise force to the rotating rod 205, and the rotating rod 205 rotates clockwise. During the clockwise rotation of the rotating rod 205, the sliding ring 2041 moves outward on the external thread 203. Under the action of the fixed rod 202, the sliding ring 2041 moves stably outward on the external thread 203. During the outward movement of the sliding ring 2041 on the external thread 203, the fixed ring 2071 moves outward on the external thread 203. With the coordinated movement of support block 2072 and connecting plate 208, the fixed ring 2071 moves outward, causing the clamping plate 209 to retract inward. Under the action of fixing part 207 and connecting plate 208, the clamping plate 209 retracts inward steadily. Conversely, when the operator applies a counterclockwise force to the rotating rod 205, the rotating rod 205 rotates counterclockwise. During the counterclockwise rotation of the rotating rod 205, the sliding ring 2041 moves inward on the external thread 203. During the inward movement of the sliding ring 2041 on the external thread 203, the fixed ring 2071 moves inward on the external thread 203. The inward movement of the fixed ring 2071 causes the clamping plate 209 to expand outward, thus realizing the clamping of the impeller side by the clamping plate 209.

[0029] In one embodiment, for the aforementioned snap-fit ​​plate 4, support plate 7, and lifting mechanism 6, a U-shaped groove 401 is provided on the top of one side of the snap-fit ​​plate 4, and a sliding groove 402 that cooperates with the support plate 7 is symmetrically provided on the bottom of one side of the snap-fit ​​plate 4; a protrusion 701 that cooperates with the sliding groove 402 is symmetrically provided on one side of the support plate 7; the lifting mechanism 6 includes a motor 601 provided at the top of the bottom of the housing 5, a rotating shaft 602 provided at the output end of the motor 601, and support blocks 603 that cooperate with the housing 5 are symmetrically provided at both ends of the rotating shaft 602, and external threads 603 are provided at both ends of the rotating shaft 602. 04, and the threads of the two external threads 604 at both ends of the rotating shaft 602 are opposite in direction. Sliding blocks 605 are symmetrically arranged at both ends of the two external threads 604. A rotating rod 606 is connected to the outer side of one set of sliding blocks 605. A rotating rod 607 that cooperates with another set of sliding blocks 605 is connected to the bottom end of the rotating rod 606. A support block 608 that cooperates with the support plate 7 is symmetrically arranged on the outer side of the rotating rod 606, thereby realizing the lifting and lowering adjustment of the support plate 7. It can effectively adapt to fans of different sizes, provide stable support for the fans, and lay a solid foundation for the smooth separation of the fan impeller.

[0030] The working principles of the snap-fit ​​plate 4, support plate 7, and lifting mechanism 6 are as follows: In the initial state, the operator adjusts the fan according to its size. Under the action of the external controller, the motor 601 is controlled and started. The output shaft of the motor 601 drives the rotating shaft 602 to rotate. Under the action of the second support block 603, the rotating shaft 602 rotates stably. During the rotation of the rotating shaft 602, the sliding block 605 moves. The sliding block 605 is respectively sleeved on the opposite thread directions of the external threads 604 at both ends of the rotating shaft 602. During the movement, the sliding block 605 will move towards each other in the horizontal direction of the rotating shaft 602. During the movement of the sliding block 605, one end of the rotating rod 606 and one end of the rotating rod 607 will move towards each other. Under the support of the support block 608, the moving of one end of the rotating rod 606 and one end of the rotating rod 607 will drive the support plate 7 to move in the vertical direction. With the cooperation of the sliding groove 402 and the protrusion 701, the support plate 7 will move stably in the vertical direction, thereby realizing the position adjustment of the support plate 7.

[0031] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0032] In practical applications, initially, the operator places the direct-drive impeller fan to be disassembled on both sides of the clamping plate 4. First, based on the fan's dimensions, the operator controls and starts the motor 601 under the control of an external controller. The output shaft of the motor 601 drives the support plate 7 to adjust its position in the vertical direction (the working principles of the clamping plate 4, support plate 7, and lifting mechanism 6 are as described above). At this point, the support plate 7 provides stable support for the fan. Based on the impeller's dimensions, the operator controls and starts the cylinder 201 under the control of an external controller. The output shaft of the cylinder 201 drives the fixing rod 202 to the fan position. Then, the operator applies force to the rotating rod 205 to effectively clamp the impeller with the clamping plate 209 (the working principle of the clamping mechanism 2 is as described above). Under the control of an external controller, the operator controls and starts the cylinder 201. The output shaft of the cylinder 201 drives the clamping plate 209 to move, thus separating the fan and impeller.

[0033] In summary, by utilizing the above-mentioned technical solution of this utility model, the present utility model, through the combined action of the clamping mechanism 2, the snap-fit ​​plate 4, the lifting mechanism 6, and the support plate 7, can effectively clamp and support direct-drive impeller fans of different sizes, ensuring that effective force can be applied to the impeller fans and improving the efficiency of impeller-fan separation. Under the action of the clamping mechanism 2, one side of impellers of different sizes can be effectively clamped, improving the stability of impeller clamping and ensuring that the cylinder 201 can effectively apply force to the impeller, making the subsequent impeller-fan separation process smoother and more efficient. Through the combined action of the snap-fit ​​plate 4, the support plate 7, and the lifting mechanism 6, the lifting and adjusting of the support plate 7 can be realized, effectively adapting to fans of different sizes, providing stable support for the fans, and thus laying a solid foundation for the smooth separation of the fan impeller.
