Description

Technical Field

[0001] This utility model relates to the field of soundproof room technology, and more specifically, to a soundproof room with an L-shaped door structure. Background Technology

[0002] Soundproof rooms are increasingly used in modern industrial production, scientific experiments, and many other environments with specific acoustic requirements. However, in workshops with large processing equipment (such as gear milling machines, gear grinding machines, and 3000 drilling machines), traditional soundproof room door structures often fail to adequately meet the needs of workpiece hoisting. For situations requiring frequent hoisting of large workpieces into and out of equipment, ordinary swing doors or sliding doors, due to their size and opening mechanisms, cannot provide sufficient operating space for hoisting equipment (such as overhead cranes). For example, swing doors occupy significant lateral space when open, while the tracks of sliding doors may interfere with the hoisting route, making the hoisting of large workpieces inconvenient and increasing the difficulty and risk of the operation.

[0003] Furthermore, large processing equipment generates significant noise during operation, and traditional soundproof room structures may not be able to effectively reduce the impact of this noise on the surrounding environment. For equipment such as gear milling machines, gear grinding machines, and 3000 drilling machines, the noise they generate has a wide frequency range and high intensity. However, the simple soundproof wall structure of traditional soundproof rooms may only provide limited isolation for some frequencies of noise, failing to meet the stringent noise control requirements within the workshop.

[0004] In addition, current soundproof rooms are generally fixedly installed inside factory buildings. In factory workshops and other environments, the production layout may change due to the optimization of production processes, the upgrading of equipment, or new production tasks. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose an L-shaped door structure soundproof room.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] An L-shaped door structure soundproof room includes a room body with an L-shaped door on the room body. An electric sliding rail is installed on the top of the room body. The L-shaped door is connected to the electric sliding rail via a slider. The electric sliding rail controls the opening and closing of the L-shaped door. A controller is fixedly installed on the outside of the room body and is electrically connected to the electric sliding rail.

[0008] Each of the four corners inside the room is fixedly fitted with an integrally formed cover plate, the bottom of which is connected to the outside. Each cover plate is equipped with a lifting and moving mechanism.

[0009] The room includes a soundproof wall, with a galvanized steel plate on the outside and a galvanized perforated plate on the inside. The soundproof wall includes two layers of damping soundproofing plates, with sound-absorbing cotton between the two layers. The surface of the sound-absorbing cotton near the galvanized perforated plate is designed as a wave shape with alternating concave and convex surfaces.

[0010] As a further description of the above technical solution: the lifting and moving mechanism includes a hydraulic cylinder fixedly installed on the inner top wall of the cover plate, and a traveling wheel is fixedly installed at the bottom of the hydraulic cylinder.

[0011] As a further description of the above technical solution: the bottom of the L-shaped door is slidably connected to a guide rail, and the guide rail is fixedly connected to the bottom front of the room.

[0012] As a further description of the above technical solution: the outer side of the galvanized steel sheet is coated with an electrostatic powder layer, and the thickness of the galvanized steel sheet is 2.0 mm.

[0013] As a further description of the above technical solution: the galvanized perforated plate 13 is a galvanized perforated plate with a thickness of 5×5×1.0mm.

[0014] As a further description of the above technical solution: a light steel keel is provided inside the soundproof wall.

[0015] As a further description of the above technical solution: the bottom of the housing is provided with a polyurethane wear-resistant coating, the thickness of which is 3-6mm.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] I. The unique L-shaped door design of this solution greatly facilitates the hoisting of large workpieces. Compared with traditional door structures, the L-shaped door provides more spaciousness when open and does not interfere with the hoisting route as much. When the overhead crane transports large workpieces in and out of the soundproof room, the L-shaped door can be controlled to open and close via an electric sliding rail, effectively reducing the risk of collisions during hoisting and improving hoisting efficiency.

[0018] Second, this solution adds concealed lifting and moving mechanisms at the four corners inside the room with the assistance of the cover plate, which facilitates the movement and adjustment of the soundproof room. During daily use of the soundproof room, the moving mechanism is retracted inside the cover plate, so that the soundproof room itself is in contact with the factory floor, ensuring the stability of the soundproof room and reducing gaps or instability that may be caused by the additional moving mechanism support.

[0019] Third, the multi-layered structure of the soundproof wall in this solution provides excellent isolation for high-intensity noise across a wide frequency range generated by processing equipment. The damping sound insulation panels effectively suppress vibrations during noise propagation, reducing secondary noise radiation. The sound insulation cotton further absorbs and isolates noise. In particular, the wavy design of the concave and convex surfaces on the side of the sound insulation cotton closest to the galvanized perforated plate increases the number of sound reflections within the cotton, lengthens the sound propagation path, and improves the absorption capacity for noise of different frequencies, thereby significantly reducing the impact of noise generated during equipment operation on the surrounding environment.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. Example 1

[0027] Please see Figure 1 , 2An L-shaped door structure soundproof room includes a room body 1, an L-shaped door 2 mounted on the room body 1, and an electric slide rail 3 installed on the top of the room body 1. The L-shaped door 2 is connected to the electric slide rail 3 via a slider, and the electric slide rail 3 controls the opening and closing of the L-shaped door 2. A controller 4 is fixedly installed on the outside of the room body 1, and the controller 4 is electrically connected to the electric slide rail 3. The unique design of the L-shaped door 2 structure greatly facilitates the hoisting of large workpieces. Compared with traditional door structures, the L-shaped door 2 provides more spacious space when open and does not cause excessive interference to the hoisting route. For example, when a crane is used to transport large workpieces in and out of the soundproof room, the L-shaped door 2 can be controlled to open and close via the electric slide rail 3, easily adapting to hoisting operations at different angles, effectively reducing the risk of collisions during hoisting and improving hoisting efficiency.

[0028] The bottom of the L-shaped door 2 is slidably connected to a guide rail 7, which is fixedly connected to the bottom front of the room body 1, increasing the stability of the L-shaped door 2 when it moves. Example 2

[0029] Please see Figure 2 , 3 This embodiment is a further improvement on Embodiment 1. Compared with Embodiment 1, each of the four corners of the soundproof room 1 is fixedly fitted with an integrally formed cover plate 5. The bottom of the cover plate 5 is connected to the outside, and each cover plate 5 is equipped with a lifting and moving mechanism 6. The lifting and moving mechanisms 6 at the four corners of the soundproof room 1 provide convenient movement within the soundproof room. In environments such as factory workshops, the production layout may change due to production process optimization, equipment upgrades, or new production tasks. The soundproof room can be easily adjusted in position within the factory using the lifting and moving mechanisms 6.

[0030] The lifting and moving mechanism 6, with the assistance of the cover plate 5, is a concealed design, making the moving equipment components invisible under normal conditions, resulting in a cleaner and more aesthetically pleasing appearance for the soundproof room. Furthermore, during daily use, the direct contact between the bottom of the soundproof room and the factory floor helps ensure its stability, reducing potential gaps or instability caused by the additional moving mechanism support. Stable grounding effectively prevents sound leakage through gaps between the ground and the bottom of the soundproof room, or reduces the reflection and transmission of vibrations generated during equipment operation within the moving mechanism, thus maintaining good sound insulation.

[0031] Specifically: The lifting and moving mechanism 6 includes a hydraulic cylinder 61 fixedly installed on the inner top wall of the cover plate 5. The bottom of the hydraulic cylinder 61 is fixedly installed with a traveling wheel 62. When the soundproof room needs to be moved, the controller 4 controls the four hydraulic cylinders 61 to extend synchronously, drive the traveling wheel 62 to descend and support the soundproof room, changing the original sliding friction to rolling friction, thereby facilitating the movement of the soundproof room.

[0032] The bottom of the room body 1 is provided with a polyurethane wear-resistant coating 8, which has a thickness of 3-6mm. The polyurethane wear-resistant coating 8 can effectively increase the wear resistance of the soundproof room. Example 3

[0033] Please see Figure 3 , 4 This embodiment is a further improvement based on Embodiment 1 or Embodiment 2. Compared with Embodiment 1 or Embodiment 2, the room body 1 includes a soundproof wall 11. The outer side of the soundproof wall 11 is provided with a galvanized steel plate 12 to provide structural strength and initial sound insulation. The inner side of the soundproof wall 11 is provided with a galvanized perforated plate 13 to reflect and scatter sound to enhance the sound absorption effect and provide support for the installation of internal equipment. The soundproof wall 11 includes two layers of damping sound insulation plates 111, and sound insulation cotton 112 is provided between the two layers of damping sound insulation plates 111. The surface of the sound insulation cotton 112 near the galvanized perforated plate 13 is designed with a wavy shape with alternating concave and convex surfaces.

[0034] The outer side of the galvanized steel sheet 12 is coated with an electrostatic powder layer 14, making the surface of the enclosure 1 wear-resistant, anti-aging, and scratch-resistant. The galvanized steel sheet 12 is 2.0mm thick, providing sufficient strength to support the overall structure of the soundproof wall 11. The galvanized perforated plate 13 is 5×5×1.0mm thick, which helps with sound diffusion. When sound hits the galvanized perforated plate 13, the mesh structure scatters the sound in different directions, thereby reducing the directional propagation of sound. Simultaneously, it works in conjunction with the inner sound insulation cotton 112 to better absorb sound. A light steel keel 113 is installed inside the soundproof wall 11, providing internal structural support for the soundproof wall 11.

[0035] Furthermore, the soundproof wall 11 employs a structure of two layers of damping sound insulation panels 111 sandwiching sound insulation cotton 112. The damping sound insulation panels 111 effectively suppress vibrations during sound propagation, reducing sound radiation caused by vibrations. The sound insulation cotton 112 further absorbs and isolates sound. Additionally, the wavy structure of the concave and convex surfaces on the surface of the sound insulation cotton 112 increases the number of sound reflections within the cotton, lengthening the sound propagation path and allowing for more opportunities for sound to be absorbed during propagation. Compared to traditional planar sound insulation cotton, this structure more effectively absorbs sound from different directions and frequencies, further enhancing the sound insulation effect of the soundproof room.

[0036] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
