Soundproof elevator and soundproof noise reduction device

Abstract

This invention discloses a soundproof elevator and a sound insulation and noise reduction device, including a damping plate and a snap-on plate. The snap-on plate has a filling cavity, and the damping plate is disposed near the filling cavity and connected to the snap-on plate through a connector. The outer wall of the damping plate is provided with an asphalt layer. The filling cavity is provided with a pad, sound-absorbing cotton, and a cement board in sequence from the inside to the outside. The pad is pressed against the inner wall of the filling cavity, and the cement board is pressed against the damping plate. Multiple keels are arranged at intervals in the filling cavity. The keels extend vertically and are connected to the inner wall of the filling cavity. The sound-absorbing cotton is divided into multiple pieces and disposed between adjacent keels. The asphalt layer on the outer wall of the damping plate can effectively absorb vibration energy. When noise is transmitted to the filling cavity through the damping plate and the cement board, the noise is transmitted along the pipe, causing the elastic element to stretch after being vibrated by the noise, which drives the buffer ball to further press against the airbag, thereby reducing the amplitude and noise. The sound insulation felt is also used for final isolation of the noise, resulting in good sound insulation and noise reduction effect.

Description

Technical Field

[0001] This invention relates to the field of elevator sound insulation technology, specifically to soundproof elevators and sound insulation and noise reduction devices. Background Technology

[0002] Elevator noise reduction is the process of reducing the noise generated by elevator operation to an acceptable level by taking effective vibration reduction, sound insulation, and sound absorption measures. Elevator noise mainly manifests as low-to-mid-frequency vibration, and its propagation mode is primarily low-frequency vibration, which is the low-frequency resonant sound energy transmitted through solids.

[0003] Therefore, the present invention proposes a soundproof elevator and a soundproofing and noise reduction device that can solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a soundproof elevator and a soundproofing and noise reduction device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A sound insulation and noise reduction device includes a damping plate and a buckle plate. The buckle plate has a filling cavity. The damping plate is disposed on a side close to the filling cavity and connected to the buckle plate by a connector. An asphalt layer is provided on the outer wall of the damping plate.

[0007] The filling cavity is provided with a pad, sound-absorbing cotton and cement board in sequence from the inside to the outside. The pad is pressed against the inner wall of the filling cavity and the cement board is pressed against the shock-absorbing plate.

[0008] As a preferred embodiment of the present invention, the filling cavity is provided with multiple keels at intervals, the keels extend vertically and connect to the inner wall of the filling cavity, and the sound-absorbing cotton is divided into multiple pieces and disposed between adjacent keels.

[0009] As a preferred technical solution of the present invention, flanges are provided on both sides of the keel for limiting and pressing the sound-absorbing cotton.

[0010] As a preferred embodiment of the present invention, a sound-insulating felt is provided between the pad and the sound-absorbing cotton.

[0011] As a preferred technical solution of the present invention, the sound-absorbing cotton and the cement board are provided with a sound-absorbing component. The sound-absorbing component includes multiple airbags and multiple rows of pipes. Each keel is fitted with an airbag. The multiple rows of pipes are connected to the cement board and are arranged laterally corresponding to the airbags. Each pipe is provided with an elastic element. One end of the elastic element is connected to the inner wall of the pipe, and the other end is provided with a buffer ball. The buffer ball abuts against the corresponding airbag.

[0012] In a preferred embodiment of the present invention, the connecting member is a connecting bolt, and a rubber ring is pressed onto the connecting member.

[0013] The present invention also provides a soundproof elevator, including the above-mentioned sound insulation and noise reduction device.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The soundproof elevator and soundproof noise reduction device of the present invention can effectively absorb vibration energy through the asphalt layer set on the outer wall of the damping plate. When noise is transmitted to the filling cavity through the damping plate and cement board, the noise is transmitted along the pipe, so that the elastic element can be stretched after being vibrated by the noise, which drives the buffer ball to further press against the airbag. The airbag can deform to absorb the noise. At the same time, the sound-absorbing cotton shell absorbs the sound transmitted directly from the cement board to the filling cavity, thereby reducing the amplitude and noise. Finally, the soundproof felt set up provides a final isolation of the noise, resulting in good soundproof noise reduction effect. Attached Figure Description

Each pipe 252 is provided with an elastic element 253, preferably a spring. One end of the elastic element 253 is connected to the inner wall of the pipe 252, and the other end is provided with a buffer ball 254. The buffer ball 254 abuts against the corresponding airbag 251.

[0030] Example 2

[0031] A sound insulation and noise reduction device includes a damping plate 10 and a buckle plate 20. The buckle plate 20 has a filling cavity. The damping plate 10 is disposed on the side close to the filling cavity and is connected to the buckle plate 20 through a connector 30. An asphalt layer 11 is provided on the outer wall of the damping plate 10. The connector 30 is a connecting bolt and a rubber ring 31 is pressed onto the connector 30.

[0032] The filling cavity is provided with a pad 21, sound-absorbing cotton 24 and cement board 26 from the inside to the outside. The pad 21 is pressed against the inner wall of the filling cavity, the cement board 26 is pressed against the damping plate 10, and a sound insulation felt 22 is provided between the pad 21 and the sound-absorbing cotton 24.

[0033] Multiple keels 23 are spaced apart inside the filling cavity. The keels 23 are made of lightweight steel and extend vertically to connect with the inner wall of the filling cavity. The sound-absorbing cotton 24 is divided into multiple pieces and placed between adjacent keels 23. Flanges are provided on both sides of the keels 23 to limit and compress the sound-absorbing cotton 24.

[0034] The sound-absorbing cotton 24 and the cement board 26 are equipped with sound-absorbing components 25.

[0035] Specifically, the sound insulation and noise reduction device effectively absorbs vibration energy through the asphalt layer 11 set on the outer wall of the damping plate 10. When noise is transmitted to the filling cavity through the damping plate 10 and the cement board 26, the noise is transmitted along the pipe 252, causing the elastic element 253 to extend after being vibrated by the noise, which drives the buffer ball 254 to further press against the airbag 251.
