Description

Technical Field

[0001] This utility model relates to a chassis vehicle that facilitates motor replacement and belongs to the field of circuit breakers. Background Technology

[0002] Circuit breaker chassis are used to safely and reliably move circuit breakers into or out of switchgear. The mechanical and electrical interlocks in the chassis are important devices to ensure the safe operation of the power grid, ensure personal safety, and prevent misoperation.

[0003] Existing chassis vehicles are usually driven by fixed motors. When the motor needs to be replaced, the circuit breaker on top must be lifted up to remove the motor and replace it. This is very inconvenient, cumbersome, and labor-intensive. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a chassis vehicle that facilitates motor replacement.

[0005] A chassis vehicle for easy motor replacement includes a base, on which a control component, a lead screw, and a drive component are mounted. The drive component, linked to the lead screw via a sprocket structure, drives the chassis vehicle. The base has a disassembly slot located behind the drive component for removing it. A mounting bracket is mounted on the disassembly slot, and a fixing plate is mounted on the drive component. The drive component is detachably connected to the mounting bracket via the fixing plate. By providing the disassembly slot, when motor replacement is needed, the operator only needs to open the slot, without having to lift the entire circuit breaker. This greatly simplifies the maintenance procedure, saves time and manpower, and improves work efficiency. Maintenance personnel can conveniently perform routine inspections and maintenance without interfering with other equipment, improving the maintainability of the equipment.

[0006] Preferably, the fixing plate includes a first fixing part that is fixedly mounted to the bottom of the motor by bolts. Second fixing parts extend from both sides of the first fixing part. The second fixing parts have first connecting holes, and the mounting bracket has second fixing holes that connect to the first connecting holes by bolts. The design between the first and second fixing parts allows for convenient and quick disassembly and reinstallation of the motor using bolts when replacing it, reducing maintenance time and improving operational efficiency. The extended design of the second fixing parts allows for adjustment of the position or direction of motors of different specifications as needed, flexibly adapting to different installation requirements and space constraints, thus improving the overall design adaptability.

[0007] Furthermore, the first fixing part and the second fixing part are arranged vertically relative to each other. The vertical arrangement design can effectively distribute the longitudinal load generated during motor operation, and the structure design is more compact, making more efficient use of limited space. Especially in application scenarios with height restrictions, it improves the flexibility and adaptability of the design.

[0008] Furthermore, the second mounting portion is located on both sides of the drive component. This provides more installation space, facilitating adaptation to drive components of different sizes and types, and enhancing system compatibility and flexibility. Operators can inspect and maintain the system from multiple directions, simplifying motor replacement and repair processes and improving maintenance efficiency.

[0009] Furthermore, the number of the first connecting hole and the second connecting hole is at least one. The number of the first connecting hole and the second connecting hole can be adjusted according to the model of the drive component.

[0010] Furthermore, there are two of each of the first and second connecting holes, arranged vertically on the second fixing part and the mounting bracket. Multiple connecting holes can evenly distribute the fixing force, increasing the connection strength between the driving component and the fixing component, reducing the risk of loosening caused by vibration or dynamic loads, thereby improving overall safety.

[0011] Preferably, the disassembly slot is L-shaped, and the fixing plate is located on the wider side of the disassembly slot. The L-shaped design provides a wider access space when replacing the motor, making it easier for operators to disassemble and install from multiple angles, and reducing the difficulty of maintenance.

[0012] Preferably, the length of the upper end of the disassembly slot is greater than the height of the drive component. A longer disassembly slot allows operators sufficient space to operate when disassembling or replacing the drive component, accommodating different sizes of drive components, enhancing the versatility and adaptability of the equipment, and enabling the system to more flexibly respond to different application needs.

[0013] Preferably, the mounting bracket has a limiting groove for limiting the lower end of the drive component. With the limiting groove, operators can install the drive component more quickly and accurately without needing to focus too much on fine-tuning the position, saving installation time and improving work efficiency.

[0014] The beneficial effects of this invention are as follows: By providing a disassembly slot, when the motor needs to be replaced, the operator only needs to open the disassembly slot, without having to lift the entire circuit breaker. This greatly simplifies the maintenance procedure, saves time and manpower, and improves work efficiency. Maintenance personnel can conveniently perform routine inspections and maintenance without interfering with other equipment, thus improving the maintainability of the equipment.

[0023] like Figure 1-3The illustration shows an embodiment of a chassis vehicle for easy motor replacement according to this utility model. It includes a base 1, on which a control component 3, a lead screw 4, and a drive component 5 are mounted. The drive component 5, through a sprocket structure, is linked to the lead screw 4 to drive the chassis vehicle. The base 1 has a disassembly slot 11 located behind the drive component 5 for removing it. A mounting bracket 2 is mounted on the disassembly slot 11, and a fixing plate 6 is mounted on the drive component 5. The drive component 5 is detachably connected to the mounting bracket 2 via the fixing plate 6. By providing the disassembly slot 11, when the motor needs to be replaced, the operator only needs to open the disassembly slot 11, without having to lift the entire circuit breaker. This greatly simplifies the maintenance procedure, saves time and manpower, and improves work efficiency. Maintenance personnel can conveniently perform daily inspections and maintenance without interfering with other equipment, improving the maintainability of the equipment.

[0024] The fixing plate 6 includes a first fixing part 61 that is fixedly mounted to the bottom of the motor with bolts. Second fixing parts 62 extend from both sides of the first fixing part 61. The second fixing parts 62 have first connecting holes 621, and the mounting bracket 2 has second fixing holes 21 that are bolted to the first connecting holes 621. The design between the first fixing part 61 and the second fixing part 62 allows for convenient and quick disassembly and reinstallation of the motor when it is replaced, reducing maintenance time and improving operational efficiency. The extended design of the second fixing part 62 allows for adjustment of the position or direction of motors of different specifications as needed, flexibly adapting to different installation requirements and space constraints, thus improving the overall design adaptability.

[0025] The first fixing part 61 and the second fixing part 62 are arranged vertically relative to each other. The vertical arrangement design can effectively distribute the longitudinal load generated during motor operation, and the structure design is more compact, making more efficient use of limited space. Especially in application scenarios with limited height, it improves the flexibility and adaptability of the design.

[0026] The second fixing part 62 is located on both sides of the drive component 5. This provides more installation space for the second fixing part 62, facilitating adaptation to drive components 5 of different sizes and types, and enhancing the system's compatibility and flexibility. Operators can inspect and maintain the system from multiple directions, simplifying the motor replacement and repair process and improving maintenance efficiency.

[0027] The number of the first connecting hole 621 and the second connecting hole is at least one. The number of the first connecting hole 621 and the second connecting hole can be adjusted according to the model of the drive component 5.

[0028] There are two connecting holes, the first 621 and the second 621, arranged vertically on the second fixing part 62 and the mounting bracket 2. Multiple connecting holes can evenly distribute the fixing force, increasing the connection strength between the driving component 5 and the fixing component, reducing the risk of loosening caused by vibration or dynamic load, and thus improving overall safety.

[0029] The disassembly slot 11 is L-shaped, and the fixing plate 6 is located on the wider side of the disassembly slot 11. The L-shaped design provides a wider access space when the motor is replaced, making it easier for operators to disassemble and install from multiple angles and reducing the difficulty of maintenance.

[0030] The length of the upper end of the disassembly slot 11 is greater than the height of the drive component 5. The longer disassembly slot 11 allows the operator sufficient space to operate when disassembling or replacing the drive component 5, accommodating different specifications of drive components 5, enhancing the versatility and adaptability of the equipment, and enabling the system to more flexibly respond to different application needs.

[0031] The mounting bracket 2 has a limiting groove 22 for limiting the lower end of the drive component 5. With the limiting groove 22, the operator can install the drive component 5 into place more quickly and accurately without having to pay too much attention to the fine adjustment of the position, saving installation time and improving work efficiency.

[0032] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
