Description

Technical Field

[0001] This invention relates to the field of capacitor maintenance technology, and in particular to an auxiliary device for rapid replacement of high-voltage capacitors in confined spaces. Background Technology

[0002] The construction of high-voltage capacitor banks requires consideration of land area, which limits the spacing between the supports for installing the capacitors. The dense arrangement of capacitors within a narrow space makes it impossible to use conventional lifting equipment to disassemble and replace faulty capacitor modules. Replacing capacitors on supports often requires the assistance of multiple people; furthermore, because maintenance personnel need to climb to heights, the operation is highly dangerous and the replacement efficiency is low. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an auxiliary device for rapid replacement of high voltage capacitors in a confined space, thereby reducing the operational risks of high voltage capacitor replacement and improving replacement efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0005] A quick replacement auxiliary device for high-voltage capacitors in a confined space includes a mobile base, a lifting support, and a capacitor storage device.

[0006] The lifting bracket is mounted on the movable base, and the capacitor storage device includes a support assembly, a translation mechanism, and a limiting platform.

[0007] The support assembly is mounted on the lifting bracket, and the translation mechanism is mounted on the support assembly;

[0008] The limiting platform is mounted on the translation mechanism and can move horizontally back and forth on the translation mechanism.

[0009] The beneficial effects of this invention are as follows: It provides an auxiliary device for rapid replacement of high-voltage capacitors in confined spaces, consisting of a movable base, a lifting support, and a capacitor storage device. During the rapid replacement of high-voltage capacitors, the device transports the high-voltage capacitors by moving the base and lifting support to the capacitor support and raising it to the position corresponding to the replacement point. This is suitable for narrow spaces on capacitor racks. Maintenance personnel only need to push the high-voltage capacitors closer to the capacitor support using the translation mechanism, then remove the capacitors and install them on the capacitor support. It is also suitable for the process of removing damaged high-voltage capacitors from the capacitor support, solving the problems of laborious handling and easy dropping of high-voltage capacitors, reducing the operational risks of high-voltage capacitor replacement, and improving replacement efficiency.

[0019] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0020] Please refer to Figures 1 to 4 A quick replacement auxiliary device for a high-voltage capacitor 6 in a confined space includes a mobile base 1, a lifting bracket 2, and a capacitor storage device.

[0021] The lifting bracket 2 is mounted on the movable base 1, and the capacitor storage device includes a support assembly 3, a translation mechanism 4, and a limiting platform 5.

[0022] The support component 3 is mounted on the lifting bracket 2, and the translation mechanism 4 is mounted on the support component 3;

[0023] The limiting platform 5 is mounted on the translation mechanism 4 and can move horizontally back and forth on the translation mechanism 4.

[0024] As can be seen from the above description, the beneficial effects of the present invention are as follows: Composed of a movable base 1, a lifting bracket 2, and a capacitor storage device, it transports the high-voltage capacitor 6 during the rapid replacement process. Through the movable base 1 and the lifting bracket 2, the high-voltage capacitor 6 is transported to the side of the capacitor bracket and lifted to the position corresponding to the replacement point. It is suitable for narrow spaces on the capacitor rack 7. Maintenance personnel only need to push the high-voltage capacitor 6 to a position close to the capacitor bracket after the translation mechanism 4 pushes it, and then remove the capacitor and install it on the capacitor bracket. It is also suitable for the process of transporting the damaged high-voltage capacitor 6 off the capacitor bracket. This solves the problems of laborious handling and easy dropping of the high-voltage capacitor 6, reduces the operational risks of replacing the high-voltage capacitor 6, and improves the replacement efficiency.

[0025] Furthermore, the translation mechanism 4 includes a horizontal guide rail 41 and a first driving member 42;

[0026] The horizontal guide rail 41 and the first driving member 42 are disposed on the support assembly 3, and the limiting platform 5 is slidably disposed on the horizontal guide rail 41;

[0027] The movable end of the first driving member 42 is connected to the limiting platform 5 and is used to drive the limiting platform 5 to slide on the horizontal guide rail 41 and can partially extend out of the horizontal guide rail 41.

[0028] As can be seen from the above description, the translation mechanism 4 consists of a horizontal guide rail 41 and a first driving component 42. The horizontal guide rail 41 has the advantages of stable guidance and smooth sliding. It slides automatically by relying on the first driving component 42, making it easy to operate.

[0029] Furthermore, the support assembly 3 includes a support platform 31, a balance bracket 32, and a connecting rod 33;

[0030] The balance bracket 32 ​​is disposed on the lifting bracket 2, and the balance bracket 32 ​​is provided with at least three extensions 34 that are centrally symmetrically distributed.

[0031] The extension 34 is connected to one end of the vertically arranged connecting rod 33, and the other end of the connecting rod 33 is connected to the support platform 31. The horizontal guide rail 41 and the first driving member 42 are both arranged on the support platform 31.

[0032] The length of the connecting rod 33 between the extension 34 and the support platform 31 is adjustable.

[0033] As can be seen from the above description, the support assembly 3 is supported by the support platform 31, the balance bracket 32 ​​and the connecting rod 33. By adjusting the length of the connecting rod 33 at different positions between the support platform 31 and the support platform 31, the balance of the support platform 31 can be adjusted so as to keep the center of gravity of the entire equipment stable after the high voltage capacitor 6 is installed on the equipment.

[0034] Furthermore, the limiting platform 5 is provided with a limiting through groove 8, and the extending direction of the limiting through groove 8 is parallel to the horizontal moving direction of the limiting platform 5.

[0035] As can be seen from the above description, the limiting through groove 8, which is parallel to its own horizontal movement direction, not only limits and fixes the high voltage capacitor 6, but also facilitates maintenance personnel to pick up and put down the high voltage capacitor 6.

[0036] Furthermore, the limiting groove 8 has a first end and a second end in the groove direction;

[0037] The first end of the limiting through groove 8 is provided with a second driving member 9. The movable end of the second driving member 9 is arranged in a horizontal direction and close to the second end. The movable end of the second driving member 9 is provided with a connecting member.

[0038] The connector is used for detachable connection with the high-voltage capacitor 6, and the second driving member 9 is used to drive the high-voltage capacitor 6 out of the limiting through groove 8.

[0039] As can be seen from the above description, by adjusting the moving position of the movable base 1 and the lifting height of the lifting bracket 2, the bottom of the limiting channel 8 can be placed against the capacitor frame 7 after the limiting platform 5 moves horizontally. Thus, the high voltage capacitor 6 can be automatically pushed into the installation position of the capacitor frame 7 by the second driving component 9, without the need for maintenance personnel to manually move the high voltage capacitor 6, simplifying the operation process and improving efficiency.

[0040] Furthermore, it also includes a remote controller;

[0041] The remote controller is wirelessly connected to the lifting bracket 2, the mobile base 1, the lifting bracket 2, the second drive component 9, and the translation mechanism 4.

[0042] As can be seen from the above description, by setting up a remote controller, the mobile base 1, the lifting bracket 2, the second drive component 9 and the translation mechanism 4 can be controlled respectively, thereby realizing the remote control of the equipment to move to the corresponding position and lift to the corresponding height. The translation mechanism 4 is used to dock with the capacitor frame 7, and the second drive component 9 is used to automatically transfer the high voltage capacitor 6, thus completing the automated replacement of the high voltage capacitor 6.

[0043] Furthermore, the limiting platform 5 includes a base plate 51 and a limiting frame 52;

[0044] The base plate 51 is disposed on the translation mechanism 4 and can move back and forth horizontally on the translation mechanism 4. The two limiting frames 52 are disposed opposite to each other on both sides of the base plate 51 perpendicular to its own horizontal movement direction to form the limiting through groove 8.

[0045] The two limiting frames 52 are used to clamp the high-voltage capacitor 6.

[0046] As can be seen from the above description, the high-voltage capacitor 6 is clamped by the limiting member to prevent it from slipping off the equipment, and at the same time, the limiting through groove 8 is formed to facilitate picking and putting.

[0047] Furthermore, the limiting frame 52 is provided with a guide part 53 whose guiding direction is close to or away from the bottom of the limiting through groove 8.

[0048] As can be seen from the above description, the limiting frame 52 is provided with a guide part 53 whose guiding direction is close to or away from the bottom of the limiting through groove 8, so that the high voltage capacitor 6 can quickly pass through the clamping ports of the two limiting frames 52 to achieve positioning.

[0049] Furthermore, the mobile base 1 is provided with a positioning element for connecting to the ground.

[0050] As can be seen from the above description, the mobile base 1 is equipped with a positioning component for connecting to the ground. After the mobile base 1 reaches the designated position, it is fixed to the ground by the positioning component to avoid position displacement during the replacement process by maintenance personnel.

[0051] Please refer to Figures 1 to 4 Embodiment 1 of the present invention is as follows:

[0052] A quick replacement auxiliary device for a high-voltage capacitor 6 in a confined space includes a movable base 1, a lifting bracket 2, and a capacitor storage device. The lifting bracket 2 is mounted on the movable base 1, and the capacitor storage device includes a support assembly 3, a translation mechanism 4, and a limiting platform 5. The support assembly 3 is mounted on the lifting bracket 2, and the translation mechanism 4 is mounted on the support assembly 3. The limiting platform 5 is mounted on the translation mechanism 4 and can move horizontally back and forth on the translation mechanism 4.

[0053] In this embodiment, combined with Figure 4 As shown, the usage process of a quick replacement auxiliary device for a high-voltage capacitor 6 in a confined space includes:

[0054] 1. Remove the damaged high-voltage capacitor 6 from capacitor rack 7.

[0055] When maintenance personnel climb up and find the high-voltage capacitor 6 that needs to be replaced on the capacitor rack 7, the maintenance personnel on the ground can push the movable base 1 to the corresponding position and use the lifting bracket 2 to lift the capacitor storage device to the same height as the high-voltage capacitor 6 that needs to be replaced. The maintenance personnel who climb up will then remove the high-voltage capacitor 6 that needs to be replaced and place it on the limiting platform 5. Then the lifting bracket 2 will be lowered and the damaged high-voltage capacitor 6 will be transported away.

[0056] 2. Transport the new high-voltage capacitor 6 onto the capacitor rack 7.

[0057] Ground maintenance personnel place the new high-voltage capacitor 6 on the limiting platform 5, then push the movable base 1 back to its previous position, and use the lifting bracket 2 to raise the capacitor storage device to the same height as the high-voltage capacitor 6 that needs to be replaced. Maintenance personnel climbing up then remove the new high-voltage capacitor 6 from the limiting platform 5 and install it on the capacitor rack 7.

[0058] Therefore, the replacement of high-voltage capacitor 6 can be completed with the cooperation of only two maintenance personnel, reducing labor costs and improving operational efficiency and safety.

[0059] In this embodiment, as Figure 2 As shown, the translation mechanism 4 includes a horizontal guide rail 41 and a first driving member 42; the horizontal guide rail 41 and the first driving member 42 are disposed on the support assembly 3, and the limiting platform 5 is slidably disposed on the horizontal guide rail 41; the movable end of the first driving member 42 is connected to the limiting platform 5, and is used to drive the limiting platform 5 to slide on the horizontal guide rail 41 and can partially extend out of the horizontal guide rail 41. The first driving member 42 can be a linear driving member such as an electric push rod.

[0060] In this embodiment, as Figure 2 and Figure 3 As shown, the support assembly 3 includes a support platform 31, a balance bracket 32, and a connecting rod 33. The balance bracket 32 ​​is mounted on the lifting bracket 2 and has at least three extensions 34 that are centrally symmetrically distributed. Each extension 34 is connected to one end of a vertically mounted connecting rod 33, and the other end of the connecting rod 33 is connected to the support platform 31. The horizontal guide rail 41 and the first driving component 42 are both mounted on the support platform 31. The length of the connecting rod 33 between the extensions 34 and the support platform 31 is adjustable.

[0061] like Figure 2 As shown, the connector is specifically assembled with bolts. By adjusting the fixed position of the extension 34 on the bolt, the distance between it and the support platform 31 is adjusted to ensure that the support platform 31 is in a horizontal state.

[0062] In this embodiment, the movable base 1 is provided with a positioning component for connecting to the ground, which can be positioned using high-mounted bolts.

[0063] In addition, in this embodiment, the lifting bracket 2 can use an electrically controlled telescopic rod or the like to improve the lifting function, and rely on the drive motor to adjust the lifting distance to achieve precise lifting of the high-voltage capacitor 6.

[0064] Please refer to Figure 3 Embodiment two of the present invention is as follows:

[0065] A quick-change auxiliary device for a high-voltage capacitor 6 in a confined space, based on the above-described embodiment one, includes a limiting groove 8 on a limiting platform 5, the extension direction of which is parallel to the horizontal movement direction of the limiting platform 5. The limiting groove 8 has a first end and a second end in the groove direction; a second driving member 9 is provided on the first end of the limiting groove 8, the movable end of the second driving member 9 is positioned horizontally and close to the second end, and a connecting member is provided on the movable end of the second driving member 9; the connecting member is used for detachable connection with the high-voltage capacitor 6, and the second driving member 9 is used to move the high-voltage capacitor 6 out of the limiting groove 8. A remote controller is wirelessly connected to the lifting bracket 2, the moving base 1, the lifting bracket 2, the second driving member 9, and the translation mechanism 4.

[0066] In this embodiment, an intelligent control system is introduced to automate the replacement of the high-voltage capacitor 6. Wireless communication technology is used to remotely control the replacement process, improving operational safety and accuracy.

[0067] After determining the approximate location of the high-voltage capacitor 6 to be replaced on the capacitor rack 7, the equipment is automatically moved via a remote controller. The required lifting height is determined by measuring the height parameters of the corresponding layer on the capacitor rack 7. Simultaneously, corresponding connecting parts can be installed on the high-voltage capacitor 6 via a connector, allowing the high-voltage capacitor 6 to be pushed into or pulled out of the capacitor rack 7 using detachable connection methods such as electronic clamping or adsorption.

[0068] Please refer to Figure 2 and Figure 3 Embodiment 3 of the present invention is as follows:

[0069] A quick-change auxiliary device for a high-voltage capacitor 6 in a confined space, based on the above-described embodiment one or two, includes a limiting platform 5 comprising a base plate 51 and limiting frames 52. The base plate 51 is mounted on a translation mechanism 4 and can move horizontally back and forth on the translation mechanism 4. Two limiting frames 52 are positioned opposite each other on both sides of the base plate 51 perpendicular to its horizontal movement direction to form a limiting through groove 8. The two limiting frames 52 are used to clamp the high-voltage capacitor 6. The limiting frames 52 are provided with guide portions 53 whose guiding direction is towards or away from the bottom of the limiting through groove 8.

[0070] In summary, the present invention provides an auxiliary device for rapid replacement of high-voltage capacitors in confined spaces, comprising a movable base, a lifting support, and a capacitor storage device. During the rapid replacement of high-voltage capacitors, the device transports the high-voltage capacitors by moving the base and lifting support to the capacitor support and raising it to a position corresponding to the replacement point. This ensures that the limiting slot on the limiting platform aligns with the installation position of the high-voltage capacitor on the capacitor rack. Then, a second driving component pushes the high-voltage capacitor onto the capacitor rack. This device is suitable for use in narrow spaces on capacitor racks and for removing damaged high-voltage capacitors from the capacitor rack. It solves the problems of laborious handling and easy dropping of high-voltage capacitors, reduces the operational risks of high-voltage capacitor replacement, and improves replacement efficiency.
