Technical Field

[0001] The utility model relates to a noise reduction and buffer device for municipal engineering construction machinery, belonging to the technical field of engineering construction. Background Art

[0002] Some mechanical tools are often used in municipal engineering, such as power tools, cutting equipment and measuring instruments, etc. Power tools such as impact drills and electric saws perform well in cutting and drilling operations, welding equipment is used to connect metal components to ensure the firmness of the structure, and measuring instruments such as total stations and levels are used to accurately measure the terrain and the height of buildings to ensure the accuracy of construction. However, when tools such as electric drills and electric picks are used during construction, it will cause very loud noise and affect the normal life of the surrounding people. Existing construction generally uses sound-absorbing sponges filled inside engineering enclosures for sound insulation.

[0003] The texture of the existing sponge layer inside the enclosure is relatively soft, resulting in insufficient overall stability of the enclosure, making it difficult to effectively absorb the impact force it bears and easily causing damage to the sponge layer. Moreover, it is difficult to absorb noise solely relying on the sponge, resulting in poor overall sound insulation effect.

[0004] Therefore, a new noise reduction and buffer device for municipal engineering construction machinery is provided to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a noise reduction and buffer device for municipal engineering construction machinery to solve the above problems. The provided noise reduction and buffer component can perform multiple noise reductions on the noise generated during construction and reduce the noise brought during construction.

A noise reduction and buffer device for municipal engineering construction machinery includes an installation shell, fixed side plates and installation nails, and also includes a noise reduction and buffer component and a connection component. One end of the fixed side plate is fixedly installed outside the installation shell, the installation nails are installed inside the fixed side plate, the noise reduction and buffer component is arranged between the installation shells, and the connection component is arranged on the side wall of the installation shell.

[0007] Preferably, the provided porous baffle has multiple small holes on its own surface for sound to pass through, so that the sound insulation board can absorb the noise in the construction area.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-6 As shown, a noise reduction and buffer device for municipal engineering machinery construction includes an installation shell 1, a fixed side plate 4 and installation nails 5, and also includes a noise reduction and buffer component 2 and a connecting component 3. One end of the fixed side plate 4 is fixedly installed outside the installation shell 1, the installation nails 5 are installed inside the fixed side plate 4, the noise reduction and buffer component 2 is arranged between the installation shells 1, and the connecting component 3 is arranged on the side wall of the installation shell 1. The provided noise reduction and buffer component 2 can assist in isolating the noise generated during construction, preventing the noise from passing through the enclosure vertical plate 205 and transmitting to the outside of the construction area. At the same time, the strip buffer plate 203 can deform and absorb and buffer the received impact force, thereby preventing the damage of this device.

[0026] As Figures 2-5As shown in the figure, the noise reduction buffer assembly 2 includes a surrounding vertical frame 201 and a porous baffle 202. The porous baffle 202 is in close contact with the surrounding vertical frame 201. A strip-shaped buffer plate 203 is provided on the back of the porous baffle 202. Connecting studs 204 are fixedly connected to the protruding parts at both ends of the strip-shaped buffer plate 203. One end of the connecting stud 204 penetrates through the inside of the surrounding vertical frame 201 and the porous baffle 202. The noise reduction buffer assembly 2 further includes a surrounding vertical plate 205. A plurality of grooves 206 evenly distributed at equal intervals are formed on the side surface of the surrounding vertical plate 205. A sound insulation pad 207 is adhered to the inner wall of the groove 206. The surface of the sound insulation pad 207 is flush with the surface of the surrounding vertical plate 205. A plurality of adjustment slotted holes are penetrated through the inside of the surrounding vertical plate 205, and the adjustment slotted holes correspond to the connecting studs 204. The noise reduction buffer assembly 2 further includes a sound insulation board 208. A mesh board 209 is provided on the back of the sound insulation board 208. The sound insulation board 208 is located between the strip-shaped buffer plate 203 and the mesh board 209. One end of the connecting stud 204 penetrates through the inside of the sound insulation board 208 and the mesh board 209 and protrudes inside the adjustment slotted hole. Nuts are screwed on the outer surfaces of the connecting studs 204. When the surrounding vertical plate 205 or the surrounding vertical frame 201 of the device is impacted and collided, the strip-shaped buffer plate 203 can be deformed to absorb and buffer the received impact force, so that it has a certain buffer protection effect, thereby alleviating the problems that due to the relatively soft texture of the sponge layer inside the enclosure, the overall stability of the enclosure is insufficient, it is difficult to effectively absorb the impact force borne, and it is easy to cause damage to the sponge layer. At the same time, the surface of the porous baffle 202 itself has a plurality of small holes for sound to pass through. The sound insulation board 208 absorbs the noise in the construction area. At this time, the sound insulation board 208 performs the first absorption of the noise, and finally the secondary absorption and sound insulation are carried out through the sound insulation pad 207, reducing the noise during construction, thereby alleviating the problem that it is difficult to absorb the noise simply by relying on the sponge, resulting in poor overall sound insulation effect.

[0027] As Figures 1-6As shown, the connecting component 3 includes a pulling plate 301. A guiding rod 302 is fixedly installed on the outer surface of the installation shell 1. The inner part of the pulling plate 301 slides on the outer surface of the guiding rod 302. A threaded rod 303 is rotatably connected to the outside of the installation shell 1. One end of the pulling plate 301 is screwed on the outer surface of the threaded rod 303. A square slot is formed on the side wall of the installation shell 1, and a connecting groove is formed on the upper part of the installation shell 1. A limiting square rod 304 slides inside the connecting groove. One end of the limiting square rod 304 is fixedly connected to the lower part of the pulling plate 301. A square block 305 is fixedly installed on the outer surface of the installation shell 1. A square groove is formed on the upper part of the square block 305. The square block 305 is inserted into the square slot. One end of the limiting square rod 304 is inserted into the square groove. When the user assembles the device body for use, the square block 305 to be assembled is inserted into the square slot. At this time, the threaded rod 303 is rotated. When the threaded rod 303 rotates, the pulling plate 301 moves downward. As the pulling plate 301 moves, it drives the limiting square rod 304 to be inserted into the square groove. As the square rod 304 is inserted, the square block 305 is limited and fixed, making the assembled fence more stable and reducing the occurrence of shaking.
