Description

Technical Field

[0001] This utility model relates to the technical field of steel spring vibration isolators, specifically an adjustable steel spring vibration isolator. Background Technology

[0002] Vibration isolators are elastic elements that connect equipment and foundations to reduce the transmission of vibration between the equipment and the foundation. They are typically installed between generator sets and infrastructure to reduce the transmission of vibration energy and noise between the generator sets and infrastructure.

[0003] Most existing adjustable steel spring vibration isolators are manually adjustable, which makes the adjustment operation cumbersome. In addition, most adjustable steel spring vibration isolators are open, which makes them susceptible to corrosion from dust, water vapor and corrosive gases during long-term use. Therefore, this utility model provides an adjustable steel spring vibration isolator. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-2This utility model provides a technical solution: it includes a base plate 1 and a top plate 2. Two fixing brackets 3 are fixedly installed on the upper surface of the base plate 1. A screw 4 is installed on the upper surface of the base plate 1 between the two fixing brackets 3. A lifting plate 5 is threadedly connected to the surface of the screw 4. A sliding groove 6 is opened on the opposite side of each of the two fixing brackets 3 to slide and connect with the lifting plate 5. A worm gear 7 is fixedly installed on the bottom of the outer wall of the screw 4. A drive motor 8 is fixedly installed on the upper surface of the base plate 1 on one side of the screw 4. A worm 9 that meshes with the worm gear 7 is fixedly installed at one end of the output shaft of the drive motor 8. Two lower spring seats 10 are fixedly installed on the upper surface of the lifting plate 5. A spring 11 is fixedly installed inside the lower spring seat 10. The top of the spring 11 is fixedly connected to the top plate 2 through an upper spring seat 12. The screw 4, lifting plate 5, sliding groove 6, worm gear 7, drive motor 8, worm 9, lower spring seats 10, spring 11 and upper spring seat 12 cooperate to form a complete system. In this setup, the drive motor 8 is first connected to an external power supply device. The controller can then control the drive motor 8 to rotate the worm gear 9. The worm gear 9 then rotates the meshing worm wheel 7 and screw 4, which in turn causes the lifting plate 5 to rise or fall. This allows for more precise and convenient adjustment of the spring's stiffness and load-bearing capacity. Two limiting slide rods 13 are slidably inserted inside each of the two fixed frames 3. One end of the limiting slide rod 13 is fixedly connected to the bottom of the top plate 2. A corrugated protective cover 14 is fixedly installed between the bottom plate 1 and the top plate 2. By setting the corrugated protective cover 14, the steel spring vibration isolator is protected and its lifespan is improved to a certain extent. The four corners of the upper surfaces of the bottom plate 1 and the top plate 2 have corresponding through-hole mounting holes. Rubber pads 15 are provided on the bottom of the bottom plate 1 and the upper surface of the top plate 2. Buffer pads 16 are provided on the upper surfaces of the two fixed frames 3.

[0020] In summary, this adjustable steel spring vibration isolator, through the coordinated arrangement of screw 4, lifting plate 5, slide 6, worm gear 7, drive motor 8, worm 9, lower spring seat 10, spring 11, and upper spring seat 12, allows for the following operation: First, the cable of drive motor 8 is connected to an external control power supply. Then, the controller can control drive motor 8 to rotate worm 9. At this time, worm 9 drives the meshing worm gear 7 and screw 4 to rotate, which in turn drives lifting plate 5 to rise or fall, thereby adjusting the stiffness and load-bearing capacity of the spring. The adjustment is more precise and convenient. By setting a corrugated protective cover 14, the steel spring vibration isolator is protected and its lifespan is improved to a certain extent.
