Detailed implementation manners

[0018] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present utility model are given for the purpose of illustration and description, and are not exhaustive or limit the present utility model to the disclosed form. Many modifications and variations will be obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.

[0019] As Figures 1-5 shown, a liftable electric control cabinet, the electric control cabinet includes a cabinet body 1, a top cover 2 detachably disposed on the top of the cabinet body 1, and a cabinet door 3 movably hinged on the front side of the cabinet body 1. A supporting base 4 is provided at the bottom of the cabinet body 1. Outer frames 5 protruding outward are provided on both sides of the cabinet body 1. The inside of the outer frames 5 is communicated with the inside of the cabinet body 1. A liftable component mounting rack 6 is installed inside the cabinet body 1. Connecting plates 7 are installed on both sides of the bottom end of the component mounting rack 6. The connecting plates 7 are located inside the outer frames 5. A rotating shaft 8 for driving the connecting plates 7 and the component mounting rack 6 to lift is also installed inside the outer frames 5. A driving member for driving the rotating shaft 8 to work is installed on the supporting base 4.

[0020] Based on the above, the electrical components inside the electric control cabinet are installed on the component mounting rack 6. When a part of the cabinet body 1 of the electric control cabinet is installed inside a sunken space and maintenance is required, the top cover 2 on the top of the cabinet body 1 can be removed. By operating the driving member and through components such as the rotating shaft 8 and the connecting plates 7, the component mounting rack 6 can be lifted from inside the cabinet body 1, facilitating the maintenance of the components.

[0021] Furthermore, the top cover 2 on the top of the cabinet body 1 is detachable. When the cabinet body 1 fails inside the sunken space and the cabinet door 3 cannot be normally opened for maintenance, the maintenance of the equipment can be achieved by using the lifting structure.

[0022] The component mounting rack 6 includes an equipment bottom plate 9, a rear baffle 10, and side baffles 11. The connecting plates 7 are fixed at the edges on both sides of the equipment bottom plate 9. The rear baffle 10 is fixed at the edge on the rear side of the equipment bottom plate 9. There are two side baffles 11, which are respectively located on both sides of the rear baffle 10 and the equipment bottom plate 9. The equipment bottom plate 9, the rear baffle 10, and the side baffles 11 are integrally provided.

[0023] The rear baffle 10 is attached to the rear side wall of the inner cavity of the cabinet body 1. The side baffles 11 are attached to the inner side walls on both sides of the inner cavity of the cabinet body 1. The edges of the side baffles 11 are bent and extended into the inside of the outer frames 5 and are attached to the inner walls of the outer frames 5. A rubber buffer pad 18 is installed at the bottom of the equipment bottom plate 9.

[0024] Based on the above, when the component mounting frame 6 is lifted or lowered, the rear baffle 10 and the side baffle 11 will fit against the inner walls of the cabinet 1 in all directions, providing a certain limiting effect to prevent the entire component mounting frame 6 from wobbling during the lifting and lowering process.

[0025] Further, a thread is provided on the outer wall of the rotating shaft 8, and the connecting plate 7 is sleeved outside the rotating shaft 8. A through hole for the rotating shaft 8 to pass through is provided on the connecting plate 7, and a thread is also provided on the inner wall of the through hole. When the rotating shaft 8 rotates, the connecting plate 7 is driven to move up and down along the direction of the rotating shaft 8 through the thread, thereby driving the component mounting frame 6 to move up and down inside the cabinet 1. When the top cover 2 is removed, the component mounting frame 6 can extend upward from the inside of the cabinet 1.

[0026] A driving cavity 12 is provided at the bottom of the outer frame 5. The rotating shaft 8 penetrates the outer frame 5 and extends into the driving cavity 12. A first gear 13 is installed at the end of the rotating shaft 8 located inside the driving cavity 12.

[0027] The driving member includes a double-shaft servo motor 14 located below the cabinet 1. The output shafts at both ends of the double-shaft servo motor 14 extend into the driving cavity 12. A crown gear 15 meshing with the first gear 13 is installed at the end of the output shaft of the double-shaft servo motor 14.

[0028] A number of balls 19 are embedded on the outer wall of the connecting plate 7, and the balls 19 are in contact with the inner wall of the outer frame 5.

[0029] Further, the double-shaft servo motor 14 is connected to a controller, and the user controls it through the controller. Bearings sleeved outside the rotating shaft 8 are provided at the top and bottom of the outer frame 5, and the rotating shaft 8 is installed inside the outer frame 5 through the bearings. When the double-shaft servo motor 14 works, it rotates through the output shafts at both ends, and drives the rotating shaft 8 to rotate inside the outer frame 5 through the engagement of the crown gear 15 and the first gear 13 at the bottom end of the rotating shaft 8, realizing the lifting control of the component mounting frame 6.

[0030] Further, during the lifting and lowering process of the connecting plate 7, the balls 19 on the outer wall will rotate in contact with the inner wall of the outer frame 5, providing a limiting effect and at the same time reducing the friction force, making the lifting and lowering of the connecting plate 7 smoother.

[0031] Connecting ears 16 are installed at the two side edges of the top cover 2. The connecting ears 16 are in contact with the top of the outer frame 5. Bolts 17 for fixedly installing the top cover 2 are provided on the connecting ears 16.

[0032] Further, the top cover 2 is installed and removed on the top of the cabinet 1 and the outer frame 5 by means of bolts 17. When the electric control cabinet is installed in a normal working place and the cabinet door 3 can be opened for maintenance, the top cover 2 does not need to be disassembled.

[0033] When the electric control cabinet is installed in a sunken space and part of the cabinet door 3 is blocked by an external structure and cannot be opened normally, the top cover 2 can be removed, and the driving member is used to drive the component mounting rack 6 to rise from inside the cabinet body 1, which is convenient for users to disassemble, assemble and maintain the components on the component mounting rack 6.

[0034] Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention. The structures, devices and operation methods not specifically described and explained in the present invention, unless otherwise specified and limited, are implemented according to the conventional means in the art.
