Description

Technical Field

[0001] This utility model relates to a gas turbine auxiliary equipment, specifically a vibration reduction and noise reduction device. Background Technology

[0002] Currently, auxiliary equipment for gas turbines on offshore floating platforms is mostly welded to a rigid plane using stranded steel coils, which are then fixed in place. While this connection method satisfies vibration reduction performance, prolonged use can lead to deformation of the steel coils, affecting aesthetics and flatness. Furthermore, significant platform sway can cause severe shaking of the equipment. For vibration-damping installations used in the electrical control boxes inside the cabin, it is necessary to not only fully meet vibration reduction performance requirements but also possess a certain degree of impact resistance and stability, while also ensuring durability and minimal deformation.

[0016] The present invention will now be described in more detail with reference to the accompanying drawings:

[0017] Combination Figure 1-5 This utility model discloses a multi-directionally installable vibration damping support, comprising an upper connecting seat 1, bolts 2, an inner fixing frame 3, a rubber vibration damping layer 4, a spring 5, a U-shaped groove fixing frame 6, and a base plate 7. The U-shaped groove fixing frame 6 is fixedly mounted on the base plate 7 by bolts; the base plate 7 has four threaded holes, and the lower end face of the U-shaped groove fixing frame 6 is connected to the base plate 7 by bolts 62. The base plate 7 also has four through holes 71 for mounting the vibration damping support as a whole on the outer plane, and the hole positions can be reasonably arranged according to the actual use scenario. The rubber vibration damping layer 4 is fixed to the inner wall of the U-shaped groove fixing frame 6 after vulcanization; the spring 5 is fitted onto the outer wall of the bottom boss of the U-shaped groove fixing frame 6 by a mating method, and is pre-compressed and installed above by the inner fixing frame 3; a threaded hole 61 is opened in the center of the boss for connecting the bolt 2. During processing, the coaxiality of the central axis of the threaded hole and the central axis of the outer wall of the boss is ensured. The upper end face of the upper connecting seat has four through holes 11 for fixing the equipment. Four through holes are opened on the lower end face of the upper connecting seat 1, and four threaded holes are opened on the upper end face of the inner fixing bracket 3. The upper connecting seat 1 is fixed to the inner fixing bracket 3 by bolts 12. The inner fixing bracket 3 is fixedly installed on the U-shaped groove fixing bracket 6 by bolts 2.

[0018] The U-shaped groove fixing bracket 6 is fixedly installed on the base plate 7 by hinged hole bolts. This base plate is a rigid fixed plane to be connected. This utility model design requires the vibration damping support to be arranged in an array to greatly improve vibration damping performance and stability.

[0019] The vibration damping rubber layer 4 is made of vulcanized rubber and is tightly bonded to the inner wall of the U-shaped channel fixing frame 6 by adhesive application. A rubber vibration damping layer is added below the U-shaped channel fixing frame 6 depending on the specific application scenario to prevent excessive cross-flow from causing rigid surface contact.

[0020] The U-shaped groove fixing bracket has a boss at the bottom, and a threaded hole is opened in the center of the top of the boss.

[0021] The spring 5 is mounted on the outer wall of the boss at the bottom of the inner fixing bracket 6 via a transition fit, and is compressed by the inner fixing bracket 3 above. The amount of compression can be adjusted by the bolt 2.

[0022] The internal fixing bracket 3 is installed on the U-shaped groove fixing bracket 6 by means of the hinge hole bolt 2.

[0023] The connecting seat 1 is fixed to the inner fixing frame 3 by means of hinged hole bolts, and has through holes for connecting equipment.

[0024] The internal fixing bracket 3 of this utility model mainly relies on pre-compressed springs 5 ​​for support. Compared with rigid fixing methods, the vibration reduction capacity is greatly improved, but the load-bearing capacity is still lacking. In actual use, it is necessary to install it in an array arrangement according to the specific usage scenario. While ensuring vibration reduction and impact resistance, this greatly improves the load-bearing capacity of the vibration damping support assembly.

[0025] For equipment with a relatively regular weight distribution, a four-point support arrangement is recommended. This satisfies both vibration reduction and load-bearing requirements while reducing material usage, making it economical and practical. For equipment with a large enclosure and concentrated internal equipment, a five-point support arrangement is preferable to maximize vibration reduction and impact resistance in the central part of the enclosure. For equipment mounted vertically against a wall, an eccentric support arrangement is the best choice. When mounted vertically against a wall, the supports bear tensile stress above and compressive stress below. Therefore, placing two supports above and three below can maximize the protection against the weight of the equipment itself.

[0026] In the internal structural connection of this utility model, spring 5 is used for vibration damping, and rubber layer 4 is applied to buffer impact loads, maximizing the vibration damping requirements of equipment such as electrical control boxes. The assembled support has a simple, square shape and compact size, suitable for various complex operating environments. This utility model has high requirements for the flatness of the upper and lower planes of each part to maximize performance. The strict requirements for the fixing connection method greatly reduce the influence of cyclic and uneven loads inside the support, improving its durability. This utility model has fewer parts, is easy to assemble and disassemble, and is simple and convenient for subsequent maintenance.
