Description

Technical Field

[0001] The utility model relates to the technical field of noise reduction devices, and particularly relates to a noise reduction device with an elastic telescopic structure. Background Art

[0002] In bridge engineering, elastic telescopic structures are widely used at the joints of bridges to adapt to the deformation of bridge structures caused by temperature changes, load effects, etc. These structures are usually composed of elastic materials and metal components, and can effectively absorb and release stress to ensure the structural integrity of the bridge. However, in actual applications, elastic telescopic structures often generate noise. Especially when vehicles pass by, due to the structural changes at the joints and the impact of vehicle loads, vibrations and impact noises will be caused. This kind of noise not only affects the quality of life of residents near the bridge, but may also have an adverse impact on the service life of the bridge.

[0003] Therefore, certain noise will be generated during the telescopic movement of the structure, and the main source of the noise is the friction and vibration effects between the structural materials caused by external forces. Therefore, if noise reduction design is required, it is necessary to start from reducing friction and suppressing vibration.

[0004] In view of the above, this application proposes a noise reduction device with an elastic telescopic structure to solve the problem. By setting an elastic component, a certain telescopic space is provided inside, so as to absorb and disperse vibration energy, and effectively suppress the noise generated by external force impact and the movement of the structure itself, achieving a certain shock absorption effect.

[0027] In order to facilitate the understanding of the technical means, creative features, achieved objectives and effects of the present utility model, the present utility model will be further described below in conjunction with specific embodiments.

[0028] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "lateral", "longitudinal", "end", "edge", "side wall", "upper", "lower", "upper part", "lower part", "directly above", "surface", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", "end", "head", "tail", etc. are based on the orientation or positional relationships shown in the drawings. They are only for the convenience of describing the technical solutions of the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0029] The present application proposes a noise reduction device with an elastic telescopic structure, which is specifically as follows;

[0030] Reference can be made to Figure 1-2 , the present application is mainly arranged in cooperation with the bridge structure 1, so that it can achieve the purpose of offsetting the structural vibration caused by external impact forces without affecting the structural integrity and operation stability. When the pre-tensioning force does not fail, it can fundamentally inhibit the generation and expansion of vibration noise, so that the structure itself can dynamically adapt to the changes of the external environment.

[0031] The structure proposed in the present application mainly includes an elastic component 2 arranged on the top of the bridge structure 1, a locking steel plate 3 arranged at the bottom of the bridge structure 1, and a telescopic component 4 arranged in the middle of the connection between the locking steel plate 3 and the elastic component 2. The telescopic component 4 moves in the middle to achieve the required use effect.

[0032] The elastic component 2 is composed of an elastic material 21, a spacer layer 22, and a steel plate 23. The elastic material 21 is connected to the spacer layer 22 and is fixedly connected to the bridge structure 1 through high-strength bolts 5. Further, in terms of materials, the elastic material 21 is made of polyurethane elastic material; the steel plate 23 is arranged in the middle of the elastic material 21 and the spacer layer 22, and the spacer layer 22 and the steel plate 23 are fixedly connected to the bridge structure 1 through reinforcing bolts 6, thereby promoting the stable installation of the elastic component 2 on the bridge structure 1, improving the durability and stability of the structure, and preventing it from losing the pre-tightening force.

[0033] The top of the telescopic component 4 is fixedly connected to the steel plate 23. Due to the material of the steel plate 23, it has a certain stability to support the movement of the telescopic component 4.

[0034] For reference Figure 1-2 , where the telescopic component 4 includes an anchor lock 41, a locking spring 42, and a locking shaft 43. The anchor lock 41 is fixedly connected to the steel plate 23 of the elastic component 2. The top of the locking spring 42 is connected to the anchor lock 41. The locking shaft 43 is stably installed on the upper surface of the locking steel plate 3 through bolts. When connecting the locking spring 42 and the locking shaft 43, first adjust the pre-tightening force and then connect the bottom to the locking shaft 43. The specific tightening force is not limited and is adjusted according to the on-site situation. After the pre-tightening force meets the requirements, connect the locking spring 42 and the bottom locking shaft 43, thereby applying an additional reverse resistance to the metal part (i.e., the steel plate 23) of the elastic component 2, so as to achieve the purpose of offsetting the structural vibration caused by external impact while not affecting the structural integrity and operational stability.

[0035] Furthermore, there are no specific restrictions on the size and shape of the telescopic component 4, which are adjusted according to the actual situation to adapt to different application environments and requirements.

[0036] At the same time, in order to promote the stable operation of the bridge structure 1 during equipment use, a sealing layer 211 is fixedly connected at the position of the bottom of the elastic material 21 corresponding to the steel plate 23, and the bottom of the sealing layer 211 is connected to the upper surface of the steel plate 23; the sealing layer 211 is made of one of sealant, sealing strip, or other waterproof and dust-proof materials; to prevent moisture, dust, or other pollutants from entering between the steel plate 23 and the elastic material 21, and avoid internal corrosion or deterioration.

[0037] Furthermore, a buffer layer 221 is fixedly connected at the position of the upper surface of the spacer layer 22 corresponding to the steel plate 23, and the top of the buffer layer 221 is connected to the lower surface of the steel plate 23; the buffer layer 221 is made of one of soft rubber or other elastic polymers. The buffer layer 221 can be used to absorb stress and vibration, reduce the impact force, protect the steel plate 23, the elastic material 21, and the structural spacer layer 22, and avoid wear and fatigue caused by direct contact.

[0038] In the present utility model, the working steps of the device are as follows:

[0039] 1. First, prepare to install the anchoring lock 41 on the steel plate 23, and connect one end of the locking spring 42 to the anchoring lock 41;

[0040] 2. Secondly, according to different bridge structures, adjust the pre-tension of the locking spring 42, and after adjustment, connect the other end of the locking spring 42 to the locking shaft 43;

[0041] 3. Then, since the locking shaft 43 is installed and fixed on the locking steel plate 3, an additional reverse resistance is applied to the main steel plate 23 part of the elastic component 2, so that it can achieve the purpose of offsetting the structural vibration caused by the external impact while not affecting the structural integrity and operation stability. Without the failure of the pre-tensioning force, the generation and expansion of vibration noise can be fundamentally suppressed, enabling the structure itself to dynamically adapt to the changes in the external environment;

[0042] 4. Finally, during operation, enhance the stability of the structure in use through the provided sealing layer 211 and buffer layer 221.

[0043] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of protection required by the present utility model. The scope of protection required by the present utility model is defined by the appended claims and their equivalents.
