Description

Technical Field

[0001] The utility model relates to the technical field of train facilities, in particular to a vibration isolation pad for a train air conditioner. Background Art

[0002] In addition to the irregularity of the rails and the unevenness of the roadbed, rail transit also generates vibrations from various equipment installed on the train. There is a gap between the air-conditioning unit hanging ears installed on the top of the train and the train mounting seat. Usually, ordinary rubber-coated steel pads are installed between the two and then fastened with bolts and nuts.

[0003] However, ordinary rubber-coated steel gaskets mainly rely on rubber to achieve vibration reduction effects. The use temperature range of rubber is narrow, it ages at high temperatures and becomes brittle at low temperatures, has a short service life and low strength. The lower the vibration frequency and the smaller the amplitude, the more difficult it is to absorb. As time goes by, the vibration reduction effect becomes worse and safety hazards arise. At the same time, the mechanical properties of the rubber-coated steel gasket itself determine that it cannot be better applied under the requirements of precise rigid connections. It is heavy and bulky, and has a high structural height. Utility Model Content

[0004] Based on the above-mentioned problems existing in the prior art, the purpose of the embodiments of the present application is to provide a train air-conditioning vibration isolation pad, including a pad body, one side of the pad body is a hollow structure, i.e., has a concave surface, a plurality of protrusions are arranged on the concave surface, and two through holes are opened on both sides of the center line of the pad body.

[0005] Furthermore, the pad body is made of a vibration-damping alloy.

[0006] Furthermore, when used for installation, the pad body is placed between the air-conditioning unit lifting ear and the mounting base, and the concave-convex design side of the hollow structure contacts the mounting base, and the air-conditioning unit lifting ear, the pad body and the mounting base are fastened together through the through holes with bolts, gaskets and nuts.

[0007] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0008] Lightweight structure and lower overall train height: The hollow structure of the vibration isolation pad reduces its own weight and is easy to install. It replaces the old rubber-coated steel pad and lowers the overall height of the train.

[0009] It has good vibration absorption and vibration reduction effect: the convex surface plays a supporting role to meet the strength and rigidity. When the vibration is transmitted to the pad, the hollow structure concave and convex design will undergo elastic deformation under the action of force. At the same time, combined with the characteristics of the material itself, the energy of vibration obstruction can be eliminated, which can achieve a good vibration reduction effect.

[0015] Now, the present application will be described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the present application in a schematic manner, and therefore only shows the components related to the present application.

[0016] like Figure 1~2 As shown, the present application provides a train air conditioning vibration isolation pad, including a pad body 1, one side of the pad body 1 is a hollow structure, i.e., has a concave surface 2, a plurality of protrusions 3 are arranged on the concave surface 2, and two through holes 4 are opened on both sides of the center line of the pad body 1.

[0017] The pad body 1 is made of a vibration-suppressing alloy. The vibration-suppressing alloy is a kind of metal material with damping properties. It can absorb amplitudes from nm to cm, and can absorb vibrations from 0.01Hz to ultrasonic frequencies. Surface treatment can be performed to improve surface performance. It has excellent molding and processing performance. It can be used at 200℃~-200℃. It has high strength and long life and does not age. When subjected to vibration load, it will cause the movement of twins in the alloy. When external force is applied, the twins undergo elastic deformation, increasing the external force to the point where they cannot withstand the formation of twins. On this basis, additional external force is added, causing the twins to grow, expand, and even generate new twins. When the external force is removed, the twins will automatically shrink until they disappear. It is precisely because of the movement of the twins that the external force is blocked, and the energy is dissipated, achieving the effect of vibration reduction. Example

[0018] like Figure 3 As shown, during installation, the pad body 1 is placed between the air-conditioning unit lifting ear 5 and the mounting seat 6, and the concave-convex design side of the hollow structure contacts the mounting seat 6, and the air-conditioning unit lifting ear 5, the pad body 1, and the mounting seat 6 are fastened together by bolts 7, gaskets 8, and nuts 9 through the through holes 4.
