[0001] This utility model belongs to the technical field of oil filling equipment lifting seat, specifically an oil filling equipment lifting seat that is easy to adjust. Background Technology

[0002] This easily adjustable oil-filled equipment riser is used in transformers and other equipment. Its height can be conveniently adjusted to meet the needs of different installation and usage scenarios. Through a flexible adjustment mechanism, it simplifies the installation and commissioning process while ensuring sealing and insulation, improving operational convenience, adapting to the dynamic height adjustment requirements of oil-filled equipment, and optimizing the user experience.

[0003] However, the hydraulic fixing structure in the commonly used adjustable oil-filled equipment lifting seat has problems such as aging of the seal ring and oil leakage, requiring regular replacement of parts and high maintenance frequency; the snap-fit ​​structure is prone to wear after long-term use, and maintenance is time-consuming and laborious, which in turn leads to a decrease in work efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable oil filling device riser to solve the problems mentioned above.

[0005] The technical solution adopted by this utility model is as follows: a conveniently adjustable oil filling equipment lifting seat includes an upper connecting plate. A plurality of screw holes are opened on the upper surface of the upper connecting plate to provide screw rods. A nut is welded to the upper surface of the screw rod. A bearing is provided at one end of the screw rod relative to the nut. A connecting plate is fixedly connected to one side of the bearing. A clamping plate is fixedly connected to one end of the connecting plate.

[0006] By adopting the above technical solution, during use, the operator can hold the nut and move the clamping plate vertically by turning the screw. The hollow design of the bearing, combined with the circular lever at the lower end of the screw, ensures that the clamping plate can be moved after the screw is rotated. This structure directly drives the clamping plate vertically by manually rotating the screw through the nut, without the need for an additional power source. The operator can use the structure manually. Common lifting seats require multiple fixing structures designed for different equipment specifications, resulting in poor versatility and requiring complete disassembly for maintenance, which is time-consuming and labor-intensive. This structure only requires rotating the screw to release the clamping force during maintenance, and can be disassembled without replacing core components. In contrast, traditional hydraulic structures may require frequent maintenance due to aging of the seals, while this mechanical transmission design is more durable, thereby reducing maintenance costs and operational complexity.

[0007] In a preferred embodiment, a plurality of support plates are fixedly connected to the lower surface of the upper connecting plate.

[0008] By adopting the above technical solution, the support plate connects the upper connecting plate and the base to form the main support frame of the lifting seat, which bears the vertical force of the equipment and ensures structural stability.

[0009] In a preferred embodiment, a base is fixedly connected to one end of the support plate relative to the upper connecting plate.

[0010] By adopting the above technical solution, the base serves as the basic component at the bottom of the riser, is fixed to the mounting plane, distributes the overall weight, and provides horizontal support.

[0011] In a preferred embodiment, a sliding plate is slidably connected to a groove on one side of the support plate.

[0012] By adopting the above technical solution, the sliding plate is slidably connected to the side groove of the support plate, and can move in the vertical direction to drive the lifting plate to rise and fall, thereby realizing the height adjustment function of the lifting seat.

[0013] In a preferred embodiment, a plurality of main support columns are fixedly connected to the lower surface of the upper connecting plate.

[0014] By adopting the above technical solution, the main support column is fixed to the lower surface of the upper connecting plate, serving as the main load-bearing structure of the lifting seat, connecting the upper connecting plate and the base, and ensuring structural rigidity.

[0015] In a preferred embodiment, a plurality of secondary support columns are fixedly connected to the lower surface of the upper connecting plate, and a plurality of buffer springs are provided at the lower end of the secondary support columns on the lower surface of the sliding plate.

[0016] By adopting the above technical solution, the auxiliary support column assists the main support column in sharing the load, enhancing the overall support strength. Especially during equipment height adjustment, it works in conjunction with the buffer spring to cushion vibrations and maintain smooth lifting. The buffer spring is installed between the lower end of the auxiliary support column and the sliding plate. Through elastic deformation, it absorbs vibration energy during equipment operation, improves the dynamic stability of the lifting seat, and extends the service life of mechanical components.

[0017] In a preferred embodiment, a lifting plate is fixedly connected to one side of the sliding plate via a fixing plate, and a placement groove is provided on the upper surface of the lifting plate.

[0018] By adopting the above technical solution, the lifting plate is connected to the sliding plate via a fixed plate, allowing for equipment height adjustment by raising and lowering the sliding plate, thus providing a stable mounting base. A placement groove is formed on the upper surface of the lifting plate to position the oil-filled equipment, preventing displacement during installation and improving assembly accuracy and sealing.

[0019] In a preferred embodiment, a plurality of air pumps are provided on the lower surface of the lifting plate.

[0020] By adopting the above technical solution, the air pump is installed on the lower surface of the lifting plate. By inflating or deflating the air, the internal air pressure is adjusted, thereby driving the lifting plate to move vertically.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0022] In this invention, during use, the operator can hold the nut and move the clamping plate vertically by turning the screw. The bearing's internal hollow design, combined with the circular lever at the lower end of the screw, ensures that the clamping plate can be moved after the screw is rotated. This structure directly drives the clamping plate vertically by manually rotating the screw through the nut, requiring no additional power source. The operator can use the structure manually. Common lifting seats require multiple fixing structures designed for different equipment specifications, resulting in poor versatility and requiring complete disassembly for maintenance, which is time-consuming and labor-intensive. This structure only requires rotating the screw to release the clamping force during maintenance, and can be disassembled without replacing core components. In contrast, traditional hydraulic structures may require frequent maintenance due to aging seals, while this mechanical transmission design is more durable, thereby reducing maintenance costs and operational complexity.

This structure directly drives the clamping plate vertically by manually rotating the nut to drive the screw, requiring no additional power source. The operator can use the structure manually. Common lifting seats require multiple fixing structures designed for different equipment specifications, resulting in poor versatility and requiring complete disassembly for maintenance, which is time-consuming and labor-intensive. This structure only requires rotating the screw to release the clamping force during maintenance, and can be disassembled without replacing core components. In contrast, traditional hydraulic structures may require frequent maintenance due to aging seals, while this mechanical transmission design is more durable, thereby reducing maintenance costs and operational complexity.

The sliding plate 9 is slidably connected to the groove on the side of the support plate 7 and can move in the vertical direction to drive the lifting plate 13 to rise and fall, thereby realizing the height adjustment function of the lifting seat.

[0033] Reference Figure 3 Multiple main support columns 10 are fixedly connected to the lower surface of the upper connecting plate 1. The main support columns 10 are fixed to the lower surface of the upper connecting plate 1 and serve as the main load-bearing structure of the lifting seat, connecting the upper connecting plate 1 and the base 8 to ensure structural rigidity.

Multiple buffer springs 12 are installed at the lower ends of the auxiliary support columns 11 on the lower surface of the sliding plate 9. The auxiliary support columns 11 assist the main support columns 10 in sharing the load, enhancing the overall support strength. Especially during equipment height adjustment, they work in conjunction with the buffer springs 12 to buffer vibrations and maintain smooth lifting. The buffer springs 12 are installed between the lower ends of the auxiliary support columns 11 and the sliding plate 9.

This structure directly raises and lowers the clamping plate vertically by manually rotating the screw, without the need for an additional power source. The operator can use the structure manually. Common lifting seats require multiple fixing structures designed for different equipment specifications, resulting in poor versatility and requiring complete disassembly for maintenance, which is time-consuming and labor-intensive. This structure only requires rotating the screw to release the clamping force during maintenance, and can be disassembled without replacing core components. In contrast, traditional hydraulic structures may require frequent maintenance due to aging seals, while this mechanical transmission design is more durable, thereby reducing maintenance costs and operational complexity.
