[0002] A switchgear is an electrical device whose main function is to open, close, control, and protect electrical equipment during the power generation, transmission, distribution, and energy conversion processes in a power system. The main components inside a switchgear include circuit breakers, disconnect switches, load switches, operating mechanisms, instrument transformers, and various protective devices.

[0003] A search revealed that publication number (CN108462065B) discloses a switch cabinet with a built-in track adjustment device. The document describes a switch cabinet comprising a cabinet body and a cabinet door, the cabinet door being rotatably mounted on the front face of the cabinet body. Two cross-shaped sliding grooves are provided on the left and right inner side walls of the cabinet body. Each cross-shaped sliding groove includes a horizontal sliding groove and a vertical sliding groove, the horizontal and vertical sliding grooves being of equal length, perpendicular to each other, and intersecting at the middle. The switch cabinet with a built-in track adjustment device of the present invention features cross-shaped sliding grooves on the left and right inner side walls, a mounting plate positioned between the symmetrical cross-shaped sliding grooves, and a fixing device on the mounting plate. The mounting plate can be adjusted horizontally and vertically within the cross-shaped sliding grooves using its rotating wheels. This design significantly reduces the difficulty of adjusting the mounting plate compared to traditional mounting plate adjustments, facilitating position changes and simplifying operation.

[0004] In practical use, the aforementioned device can improve the adjustment position of the mounting plate compared to traditional mounting rails. However, this solution still requires bolt fixing during adjustment, and the mounting plate can only be adjusted horizontally and vertically. In actual use of switch cabinets, different electrical equipment is often installed, including large electrical equipment and small electrical switches. Therefore, different mounting plates need to be replaced according to actual use needs. However, the aforementioned device and existing equipment are not convenient for quick disassembly and installation of the mounting plate, and the adjustment range of the position is limited, resulting in low practicality.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] While the aforementioned patented devices can improve the adjustment position of the mounting plate compared to traditional mounting rails in practical use, this solution still requires bolt fixing during adjustment, and the mounting plate can only be adjusted horizontally and vertically. In actual use of switch cabinets, different electrical equipment is often installed, including large electrical equipment and small electrical switches. Therefore, different mounting plates need to be replaced according to actual usage needs. However, the aforementioned devices and existing equipment are not convenient for quick disassembly and installation of the mounting plate, and the adjustment range of the position is limited, resulting in low practicality.

[0022] Therefore, the present invention provides an adjustable track structure for electrical equipment installation in switchgear. See [link / reference] Figures 1-10As shown, it includes a switch cabinet 1. Two supporting vertical rails 2 are symmetrically arranged on both sides of the interior of the switch cabinet 1. The supporting vertical rails 2 are fixedly connected to the switch cabinet 1. Connecting crossbeams 3 are slidably connected to the outer sides of the two supporting vertical rails 2 on the same side. The supporting vertical rails 2 are I-shaped and fixed to the switch cabinet 1 by bolts. The I-shaped design of the supporting vertical rails 2 allows the connecting crossbeams 3 to be easily slidably connected to the supporting vertical rails 2, while also providing lateral limitation for the connecting crossbeams 3. An adjustment component is provided at the position between the connecting crossbeams 3 and the supporting vertical rails 2 to adjust the position of the connecting crossbeams 3. The two connecting crossbeams 3... Each end is equipped with a connecting longitudinal frame 6, and an electrical mounting plate 5 is installed at the top of the connecting longitudinal frame 6. The structural design of the connecting longitudinal frame 6 and the electrical mounting plate 5 allows for the quick installation of large electrical equipment via the connecting longitudinal frame 6, facilitating the installation of the electrical equipment. The electrical mounting plate 5 is slidably connected to the connecting longitudinal frame 6. A switch mounting plate 4 is provided on one side of the connecting longitudinal frame 6, and plug-in plates 28 are fixed at both ends of the switch mounting plate 4. A connecting groove 30 is provided on the inner side of the connecting longitudinal frame 6 at a position corresponding to the plug-in plate 28. The plug-in plate 28 is plugged into the connecting longitudinal frame 6 through the connecting groove 30. Furthermore, a plug-in assembly is provided at the position corresponding to the plug-in plate 28. Through the structural design of the switch mounting plate 4 and the plug-in assembly, the switch mounting plate 4 and the connecting longitudinal frame 6 can be installed using a plug-in method. This allows the electrical switch to be pre-installed on the switch mounting plate 4 during initial installation, and then the switch mounting plate 4 can be directly connected to the connecting longitudinal frame 6. This reduces the inconvenience caused by limited space when installing electrical switches inside the switch cabinet 1. Limiting components are provided at both ends of the connecting longitudinal frame 6, corresponding to the connecting cross frame 3, to adjust the longitudinal position of the connecting longitudinal frame 6; the lower side of the electrical mounting plate 5 has four... Each corner is fixed with a mounting block 26. Multiple mounting slots 27 are evenly provided at the positions corresponding to the mounting blocks 26 on the connecting longitudinal frame 6. The mounting blocks 26 are inserted into the connecting longitudinal frame 6 through the mounting slots 27. Through the structural design of the mounting blocks 26 and the mounting slots 27, when it is necessary to install the electrical mounting plate 5 to the connecting longitudinal frame 6, the electrical mounting plate 5 can be directly inserted into the mounting slots 27 through the mounting blocks 26 to complete the installation of the electrical mounting plate 5. After the electrical equipment is installed on the electrical mounting plate 5, the electrical mounting plate 5 can be limited to prevent horizontal slippage of the electrical mounting plate 5, thereby improving the convenience of installation and disassembly of the electrical mounting plate 5.

[0023] For details, see Figures 2-5As shown, the adjustment assembly includes a movable plate 11, which is disposed inside the connecting crossbeam 3 and slidably connected to the connecting crossbeam 3. To facilitate the connection and positioning of the connecting crossbeam 3 and the supporting vertical rail 2, limit bolts 12 are fixed at both ends of the movable plate 11 near the supporting vertical rail 2. The limit bolts 12 are slidably connected to the connecting crossbeam 3. Limit holes 18 are opened at the corresponding positions of the supporting vertical rail 2 and the limit bolts 12. The limit bolts 12 are inserted into the supporting vertical rail 2 through the limit holes 18. To facilitate the movement of the movable plate 11, a fastening screw 13 is threadedly connected to the middle of the movable plate 11. The fastening screw 13 is rotatably connected to the connecting crossbeam 3, and one end of the fastening screw 13 extends to the outside of the connecting crossbeam 3. To facilitate the rotation of the fastening screw 13, an adjustment knob 14 is fixed at the end of the fastening screw 13 located on the outside of the connecting crossbeam 3. Multiple second positioning grooves 34 are evenly provided on both sides of the vertical rail 2 at positions corresponding to the connecting crossbar 3. A first positioning component is provided on the inner side of the connecting crossbar 3 at a position corresponding to the second positioning groove 34. Through the structural design of the first positioning block 19, the first positioning spring 20, and the second positioning groove 34, the connecting crossbar 3 can be easily positioned when adjusting its position, allowing it to move to the position corresponding to the limiting bolt 12 and the limiting hole 18. The first positioning component includes a first positioning spring 20, which is located on the inner side of the connecting crossbar 3. One end of the first positioning spring 20 is fixedly connected to the supporting vertical rail 2, and the other end of the first positioning spring 20 is fixed to the first positioning block 19. The first positioning block 19 is slidably connected to the supporting vertical rail 2 and is inserted into the supporting vertical rail 2 through the second positioning groove 34.

[0024] During installation, the supporting vertical rail 2 is first bolted to the designated position. Then, the connecting horizontal frame 3 is installed above the supporting vertical rail 2, fitted onto its outer side. The supporting vertical rail 2 then presses against the first positioning block 19, causing it to move closer to the first positioning spring 20. When the connecting horizontal frame 3 reaches the position where the first positioning block 19 corresponds to the second positioning groove 34, the elasticity of the first positioning spring 20 pushes the first positioning block 19 into the inner side of the second positioning groove 34. At this point, the operator can stop moving the connecting horizontal frame 3 by feeling the first positioning block 19 inserted into the inner side of the second positioning groove 34. Simultaneously, the first positioning block 19 provides auxiliary limiting for the connecting horizontal frame 3. Then, by rotating the adjusting knob 14, the fastening screw 13 rotates. As the fastening screw 13 rotates, the connecting horizontal frame 3 is moved... Plate 11 drives the limit bolt 12 to move closer to the support vertical rail 2. When the limit bolt 12 moves to the inside of the limit hole 18, the connection limit between the connecting crossbeam 3 and the support vertical rail 2 is completed. When it is necessary to adjust the height of the connecting crossbeam 3, rotate the adjustment knob 14 in the opposite direction to disengage the limit bolt 12 from the limit hole 18. Repeat the above operation to adjust the connecting crossbeam 3 to a suitable height. When it is necessary to install large electrical equipment, first place the two connecting longitudinal frames 6 at both ends of the connecting crossbeam 3 through the limit assembly. Then connect the electrical mounting plate 5 to the connecting longitudinal frame 6 through the mounting block 26 and the mounting groove 27. Then install the electrical equipment on the upper end of the electrical mounting plate 5. When it is necessary to install multiple electrical switches, first install the electrical switches on the switch mounting plate 4. Then connect the switch mounting plate 4 to the connecting crossbeam 3 through the plug plate 28 and the plug assembly.

[0025] Among them, see Figure 7 and Figure 8As shown, the limiting assembly includes a connecting slider 10, which is fixed to the lower end of the connecting longitudinal frame 6. A sliding groove 15 is provided at the top of the connecting transverse frame 3 at a position corresponding to the connecting slider 10. The connecting slider 10 is slidably connected to the connecting transverse frame 3 through the sliding groove 15. A limiting frame 23 is slidably connected to one side of the connecting slider 10. Through the structural design of the connecting slider 10 and the limiting frame 23, the connecting longitudinal frame 6 and the connecting transverse frame 3 can be connected and laterally limited to complete the installation. Multiple limiting grooves 17 are evenly provided on one side of the connecting transverse frame 3 at a position corresponding to the limiting frame 23. The limiting frame 23 is engaged with the connecting transverse frame 3 through the limiting grooves 17. Both ends of the limiting frame 23 extend into the inner side of the connecting slider 10. Connecting blocks 21 are fixed at both ends of the limiting frame 23 located inside the connecting slider 10. 21 is slidably connected to the connecting slider 10. To facilitate the limiting frame 23, a telescopic spring 22 is fixed to the top of the connecting block 21, and the top of the telescopic spring 22 is fixedly connected to the connecting slider 10. To facilitate the positioning of the limiting frame 23 and the limiting groove 17, a plurality of first positioning grooves 16 are evenly provided on the inner side of the connecting cross frame 3 at the position corresponding to the connecting slider 10. A second positioning block 25 is provided on the inner side of the connecting slider 10 at the position corresponding to the first positioning groove 16. The second positioning block 25 is slidably connected to the connecting slider 10. The second positioning block 25 is inserted into the connecting cross frame 3 through the first positioning groove 16. To facilitate the limiting of the second positioning block 25, a second positioning spring 24 is fixed to the top of the second positioning block 25, and the top of the second positioning spring 24 is fixedly connected to the connecting slider 10.

[0026] During operation, when connecting the longitudinal frame 6 and the transverse frame 3, the connecting slider 10 is first installed inside the sliding groove 15. At the same time, the limiting frame 23 is pushed upward, causing it to move closer to the telescopic spring 22. Then, it moves to the longitudinal frame 6, causing the transverse frame 3 to press the second positioning block 25, causing it to move closer to the second positioning spring 24. When the longitudinal frame 6 moves to the position where the second positioning block 25 corresponds to the first positioning groove 16, the second positioning block 25 is pushed into the first positioning groove 16 under the elastic action of the second positioning spring 24. After positioning, the limiting frame 23 is released, and the connecting block 21 and the limiting frame 23 are pushed downward under the elastic action of the telescopic spring 22, causing the limiting frame 23 to move into the limiting groove 17, thus completing the installation and limiting of the longitudinal frame 6. When the position of the longitudinal frame 6 needs to be adjusted, the limiting frame 23 is moved upward, and then the longitudinal frame 6 is moved. The above operation is repeated to complete the position adjustment of the longitudinal frame 6.

[0027] Among them, see Figure 10As shown, to facilitate limiting the position of the plug-in plate 28, the plug-in assembly includes a plug-in block 32. The plug-in block 32 is disposed inside the connecting longitudinal frame 6 and is slidably connected to the connecting longitudinal frame 6. To facilitate limiting the position of the plug-in block 32, a plug-in spring 31 is fixed to the end of the plug-in block 32 away from the plug-in plate 28. To facilitate moving the plug-in block 32, a lever 33 is fixed to one side of the plug-in block 32. The lever 33 extends to the outside of the connecting longitudinal frame 6 and is slidably connected to the connecting longitudinal frame 6. A plug-in slot 29 is provided at the position corresponding to the plug-in block 32 on the plug-in plate 28. The plug-in block 32 is plugged into the plug-in plate 28 through the plug-in slot 29. In order to facilitate the limiting and organization of the electrical switch wiring harness, a fixing plate 7 is provided at the lower position of the switch mounting plate 4. Multiple connecting rods 8 are provided at the position between the fixing plate 7 and the lower end of the connecting longitudinal frame 6. The two ends of the connecting rods 8 are fixedly connected to the fixing plate 7 and the connecting longitudinal frame 6 respectively. Multiple wire fixing rings 9 are evenly fixed on the other side of the fixing plate 7.

[0028] During operation, when it is necessary to connect the switch mounting plate 4 to the connecting frame 6, the switch mounting plate 4 is inserted into the inner side of the connecting groove 30 through the plug plate 28. When the plug plate 28 moves, it first presses the plug block 32, causing the plug block 32 to move to the inner side of the plug spring 31. When the plug plate 28 moves to the position corresponding to the plug block 32 in the plug groove 29, the plug block 32 is moved closer to the plug plate 28 under the elastic action of the plug spring 31. When the plug block 32 moves to the inner side of the plug groove 29, the plug plate 28 is limited, thereby completing the installation of the switch mounting plate 4.

[0029] In summary, this solution effectively addresses the problem that while the aforementioned patented device can improve the adjustment position of the mounting plate compared to traditional mounting rails in practical use, this solution still requires bolt fixing during adjustment, and the mounting plate can only be adjusted horizontally and vertically. In actual use of switch cabinets, various electrical devices are often installed, ranging from large to small electrical switches. Therefore, different mounting plates need to be replaced according to actual usage needs. However, the aforementioned device and existing equipment are inconvenient for quick disassembly and installation of the mounting plate, and the adjustment range is limited, resulting in low practicality.

[0030] Working principle: During installation, the supporting vertical rail 2 is first bolted to the designated position. Then, the connecting horizontal bracket 3 is installed above the supporting vertical rail 2, fitted onto the outside of the supporting vertical rail 2. The supporting vertical rail 2 will then press against the first positioning block 19, causing the first positioning block 19 to move closer to the first positioning spring 20. When the connecting horizontal bracket 3 moves to the position where the first positioning block 19 corresponds to the second positioning groove 34, the elasticity of the first positioning spring 20 pushes the first positioning block 19 into the inner side of the second positioning groove 34. At this point, the operator can stop moving the connecting horizontal bracket 3 by feeling the first positioning block 19 when it is inserted into the inner side of the second positioning groove 34. Simultaneously, the first positioning block 19... The connecting crossbeam 3 is then partially limited. The adjusting knob 14 is rotated, causing the fastening screw 13 to rotate. As the screw rotates, the moving plate 11 moves the limiting bolt 12 closer to the supporting vertical rail 2. When the limiting bolt 12 reaches the inside of the limiting hole 18, the connection between the connecting crossbeam 3 and the supporting vertical rail 2 is complete. To adjust the height of the connecting crossbeam 3, the adjusting knob 14 is rotated in the opposite direction, disengaging the limiting bolt 12 from the limiting hole 18. This process can be repeated to adjust the connecting crossbeam 3 to a suitable height. When installing large electrical equipment, the two connecting longitudinal frames 6 are first positioned on the connecting crossbeam 3 using the limiting assembly. At both ends, the electrical mounting plate 5 is then connected to the connecting longitudinal frame 6 via the mounting block 26 and the mounting groove 27. The electrical equipment is then installed on the upper end of the electrical mounting plate 5. When multiple electrical switches need to be installed, they can first be installed on the switch mounting plate 4, and then the switch mounting plate 4 is connected to the connecting cross frame 3 via the plug-in plate 28 and the plug-in assembly. When connecting the connecting longitudinal frame 6 to the connecting cross frame 3, the connecting slider 10 is first installed inside the sliding groove 15, and simultaneously the limit frame 23 is pushed upwards, causing the limit frame 23 to move closer to the telescopic spring 22, and then to the connecting longitudinal frame 6, causing the connecting cross frame 3 to press against the second positioning block. 25, causing the second positioning block 25 to move closer to the second positioning spring 24. When the connecting longitudinal frame 6 moves to the position where the second positioning block 25 corresponds to the first positioning groove 16, the second positioning block 25 is pushed into the inner side of the first positioning groove 16 under the elastic action of the second positioning spring 24. After positioning, the limiting frame 23 is released. Under the elastic action of the telescopic spring 22, the connecting block 21 and the limiting frame 23 are pushed downward, causing the limiting frame 23 to move into the inner side of the limiting groove 17, thus completing the installation and limiting of the connecting longitudinal frame 6. When it is necessary to adjust the position of the connecting longitudinal frame 6, the limiting frame 23 is moved upward, and then the connecting longitudinal frame 6 is moved. The above operation is repeated to complete the position adjustment of the connecting longitudinal frame 6.When it is necessary to connect the switch mounting plate 4 to the connecting longitudinal frame 6, the switch mounting plate 4 is inserted into the inner side of the connecting groove 30 via the plug-in plate 28. As the plug-in plate 28 moves, it first presses against the plug-in block 32, causing the plug-in block 32 to move inside the plug-in spring 31. When the plug-in plate 28 moves to the position corresponding to the plug-in block 32 in the plug-in groove 29, the elastic force of the plug-in spring 31 moves the plug-in block 32 closer to the plug-in plate 28. When the plug-in block 32 moves inside the plug-in groove 29, the plug-in plate 28 is limited, thus completing the installation of the switch mounting plate 4.
