Description

Technical Field

[0001] This utility model relates to the field of iron-core reactor technology, specifically a tensioning mechanism for iron-core reactors. Background Technology

[0002] As shown in the core tensioning structure of a low-noise dry-type iron-core reactor disclosed in CN218069573U, the tensioning structure of the iron-core reactor generally adopts a screw and nut configuration. Whether the screw structure is vertical or inclined and cross-configured, the purpose and adjustment method are to achieve tension by adjusting the position of the nut relative to the screw. Since the screw cannot be bent, it needs to be set on both the front and back sides, and when tensioning, both the front and back sides need to be adjusted separately. It is also necessary to ensure that the adjustment of the front and back sides is basically synchronized to avoid the occurrence of different tightness between the front and back sides. In addition, to ensure the above effect, the nuts need to be tightened alternately. Utility Model Content

[0003] To address the problems of complex adjustment process and poor applicability of the aforementioned screw-type tensioning method, this utility model provides a tensioning mechanism for iron-core reactors.

[0004] The technical solution of this utility model is as follows: A tensioning mechanism for an iron-core reactor includes multiple pressure-bearing frames disposed on the upper and lower sides of the iron-core reactor, and the two pressure-bearing frames disposed on the upper and lower sides are connected by the same tensioning rope. Both ends of a single tension rope are fixed to the ends of the same pressure frame on the front and rear sides of the iron core reactor, and pass around the pressure frame corresponding to its respective side; An adjusting component is also provided on the pressure frame where the ends of the tension rope are not fixed. The adjusting component can move relative to the pressure frame in a direction away from or towards the iron core reactor. The end of the adjusting component away from the pressure frame is in constant contact with the tension rope.

[0005] Unlike conventional methods that use vertical screws for tensioning, this device uses a tensioning rope for tensioning. Furthermore, the pressure-bearing frames on both the upper and lower sides can be tensioned using only one tensioning rope. In addition, the device can be adjusted to meet different needs by adjusting the adjustable parts to ensure the tension is achieved.

[0006] To facilitate the installation of the tension rope, the two bearing frames connected by a single tension rope are located in the same vertical plane.

[0007] To adapt to various application scenarios, a support is provided between the adjustment component and the tensioning rope.

[0008] The specific structure of the aforementioned adjusting component is that the adjusting component is a bolt, and the supporting component can rotate relative to the adjusting component along its central axis.

[0009] For limiting the position, both ends of the pressure frame are provided with openings through which tension ropes can pass.

[0010] The method of achieving end limiting of the tension rope is that the end of the tension rope is fixedly provided with a limiting end that cannot pass through the opening.

[0011] As a preferred embodiment, the adjusting element is located in the middle of the pressure-bearing element.

[0012] To limit the position of the tension rope, the support is provided with a groove to accommodate the tension rope.

[0013] As a preferred embodiment, the end of the tension rope is fixed to a pressure-bearing frame provided on the lower side of the iron-core reactor.

[0014] To ensure the effectiveness of the tension rope, the main body of each tension rope is always located in the same vertical plane.

[0015] The beneficial effects of this utility model are as follows: This utility model is a tensioning mechanism for iron-core reactors. Unlike the tensioning method that uses screws and nuts, this device uses a single tensioning rope instead of two screws. Furthermore, its tensioning method does not rely on adjusting the positions of the nuts on both sides, but can directly adjust the adjusting component located in the middle, which can ensure balanced tensioning action. Only one adjusting component needs to be adjusted. Based on this, different support components can be selected for adaptation according to different scenarios. Attached Figure Description

[0016] The advantages and solutions of this application will become clear to those skilled in the art upon reading the following detailed description of preferred embodiments. The accompanying drawings are for illustrative purposes only and are not intended to limit the scope of this invention.

Bracket; 11. Positioning groove; 2. Iron core; 3. Pressure bearing frame; 4. Tensioning rope; 5. Limiting end; 6. Adjusting component; 7. Supporting component. Detailed Implementation

[0018] Example like Figure 1 , 2 The tensioning mechanism for an iron-core reactor shown includes multiple pressure-bearing frames 3 disposed on the upper and lower sides of the iron-core reactor. The iron-core reactor includes an iron core 2 and upper and lower supports 1. Its structure and function are conventional and will not be described in detail. It should be noted that, in order to adapt to this structure, the side of the support 1 away from the iron core 2 is provided with a positioning groove 11, and the pressure-bearing frame 3 can be inserted into the positioning groove 11 to ensure that the position of the support 1 is constant. Then, the two pressure-bearing frames 3 disposed on the upper and lower sides are connected by the same tensioning rope 4. Since the purpose is to tighten, the two pressure-bearing frames 3 on the upper and lower sides can be tilted relative to each other. However, in order to facilitate the installation of the tensioning rope 4, the two pressure-bearing frames 3 connected by a single tensioning rope 4 are located in the same vertical plane.

[0019] It should be noted that, in order to facilitate the tensioning of the core reactor by the tensioning rope 4, both ends of a single tensioning rope 4 are respectively fixed to the ends of the same bearing frame 3 on the front and rear sides of the core reactor, i.e., as shown in the figure. Figure 1 , 2 As shown, the tension rope 4 is U-shaped and its opening faces upward or downward. This method facilitates fixing the tension rope 4 on one side and also makes it easier to tighten the tension rope 4.

[0020] Specifically, an adjusting element 6 is provided on the pressure-bearing frame 3, where the ends of the tension rope 4 are not fixed. That is, the adjusting element 6 is located in the middle section of the U-shaped tension rope 4. For ease of adjustment, the adjusting element 6 can move relative to the pressure-bearing frame 3 in a direction away from or towards the iron core reactor. In this way, as... Figure 3 , 4 As shown, the end of the adjusting member 6 can be displaced relative to the iron core reactor. Through the above displacement, the tension of the tensioning rope 4 can be adjusted to meet the tensioning requirements.

[0021] It should be noted that the end of the adjusting member 6 away from the pressure frame 3 is in real-time contact with the tension rope 4. That is to say, during the adjustment of the position of the adjusting member 6, the tension rope 4 is synchronized in real time. Therefore, after adjusting the position of the adjusting member 6, the adjustment effect of the tension rope 4 can be obtained.

[0022] As can be seen, in the above structure, after the tension rope 4 is fixed, only the adjusting component 6 needs to be adjusted to adjust the tension rope 4 synchronously. Therefore, for ease of use, the end of the tension rope 4 is fixed to the pressure-bearing frame 3 provided on the lower side of the iron core reactor. That is to say, the adjusting component 6 is set on the upper pressure-bearing frame 3, which makes it convenient for the staff to adjust it from the top. If it is set at the bottom, it will be inconvenient to operate at the bottom after the above structure is installed.

[0023] Based on the above structure, furthermore, to adapt to various application scenarios, a support member 7 is provided between the adjusting member 6 and the tension rope 4. The purpose of the support member 7 is to cooperate with the adjusting member 6 to resist and restrict the tension rope 4. Relying solely on the adjusting member 6 is not convenient for limiting the tension rope 4, especially during the adjustment process, as adjusting the adjusting member 6 may cause the tension rope 4 to displace. Therefore, an additional support member 7 is required. In order to restrict the position of the tension rope 4, the support member 7 is provided with a groove to accommodate the tension rope 4, such as... Figure 4 As shown, the presence of the groove ensures that the tension rope 4 will not come off from the sides after being tightened.

[0024] And as Figure 4 As shown, the specific structure of the adjusting member 6 is as follows: the adjusting member 6 is a bolt, and the adjustment method is to rotate it with a tool. Since the adjusting member 6 needs to rotate, and the existence of the groove causes the support member 7 to not rotate, it should also be noted that the support member 7 can rotate relative to the adjusting member 6 along its central axis. In use, it is only necessary to tighten the adjusting member 6 with a tool, and it can be ensured that the support member 7 always plays a role and does not affect the normal use of the adjusting member 6.

[0025] The above structure achieves this, unlike the conventional method of tightening via a vertical screw. This device uses a tensioning rope 4 for tightening, and the upper and lower pressure-bearing frames 3 for tightening can be tightened with only one tensioning rope 4. Furthermore, the tensioning rope 4 can be adjusted and adapted to different needs using the adjusting component 6 to ensure tightness. A support component 7 can also be set between the adjusting component 6 and the tensioning rope 4. The support component 7 not only limits the tensioning rope 4 but also adapts to different application scenarios by using support components 7 of different specifications and thicknesses. In addition, the groove width design can be different to accommodate tensioning ropes 4 of different diameters.

[0026] In a preferred embodiment, to limit the tension rope 4, both ends of the pressure-bearing frame 3 are provided with openings through which the tension rope 4 can pass. The tension rope 4 is thus limited by having a fixed limiting end 5 at its end that cannot pass through the opening. This ensures that the tension rope 4 is limited after passing through the opening, resulting in strong overall stability and reducing the likelihood of dislocation during tensioning. Furthermore, for easy adjustment, the adjusting element 6 is located in the middle of the pressure-bearing component.

[0027] Finally, to ensure the effectiveness of the tension rope 4, the main body of each tension rope 4 is always located in the same vertical plane to avoid the tension rope 4 being tilted and thus losing its original position, resulting in a better tensioning effect.
