Description

Technical Field

[0001] The utility model relates to the technical field of noise reduction, in particular to a detachable and movable construction site noise reduction device. Background Art

[0002] Construction noise is universal. Since the objects of construction projects are various places and buildings in cities and towns, any location in the city may become a construction site. Therefore, urban residents may be disturbed by noise caused by construction everywhere around their lives, studies, and workplaces. Effectively blocking the noise during its propagation process can reduce the interference of noise on nearby residents.

[0003] The inventors of this application have found the following problems in practical use:

[0004] Currently, noise reduction panels are generally single-board structures. When transporting them to a designated location, they need to be carried manually or by cart. In addition, single-board noise reduction panels cannot adapt to noise sources at different heights. When it is necessary to block noise sources at higher positions, multiple noise reduction panels need to be transported and assembled, which takes a long time.

[0005] Therefore, it is necessary to provide a detachable and movable construction site noise reduction device to solve the above technical problems. Utility Model Content

[0006] The technical problem to be solved by the present invention is to solve the problem of transporting and building multiple noise reduction panels, which is time-consuming. In view of the above-mentioned defects of the prior art, a detachable and movable construction site noise reduction device is provided.

[0007] To achieve the above-mentioned purpose, the technical solution of the utility model is: a detachable and movable construction site noise reduction device, comprising a first noise reduction plate and a second noise reduction plate, the tops of the first noise reduction plate and the second noise reduction plate are rotatably connected by a rotating shaft, the bottom of the first noise reduction plate is fixedly connected to a first moving mechanism, and the bottom of the second noise reduction plate is fixedly connected to a second moving mechanism, and the first noise reduction plate and the second noise reduction plate are used to block the spread of construction production noise at different heights.

[0008] By adopting the above technical solution, the tops of the first noise reduction plate and the second noise reduction plate are rotatably connected through a rotating shaft, so that the two noise reduction plates can be flexibly unfolded or folded, thereby adapting to construction and production noise sources at different heights, thereby enhancing the flexibility and applicability of the noise reduction device. Whether it is near a low steel bar processing shed or next to a tall pump truck or cement mixer truck, effective noise blocking can be achieved by adjusting the height of the noise reduction plate.

[0009] It is further configured that the back of the second noise reduction plate is rotatably connected to the first support rod, one end of the first support rod is rotatably connected to the second support rod, and the back of the first noise reduction plate is fixedly connected to a clip, and the clip is engaged with the second support rod.

[0010] By adopting the above technical solution, the first support rod connected to the back of the second noise reduction plate and the second support rod connected thereto provide a stable support system for the noise reduction device. When the second noise reduction plate needs to be unfolded to increase the noise reduction area, the angle of the first support rod and the second support rod can be adjusted to keep the second noise reduction plate in a stable unfolded state, thereby effectively blocking the spread of construction production noise at high altitudes.

[0011] It is further provided that the first noise reduction plate and the second noise reduction plate both include an enclosure frame body, and a backboard, glass fiber sound-absorbing cotton, a steel wire mesh and a perforated sound-absorbing metal plate are sequentially arranged inside the enclosure frame body.

[0012] By adopting the above technical solution, the first noise reduction board and the second noise reduction board both use the enclosure frame as structural support, which not only enhances the overall strength and stability of the noise reduction board, but also provides effective protection for the sound-absorbing material inside it.

[0013] It is further provided that the four corners of the enclosure frame body are rotatably connected with rotating clips, and the rotating clips are used to fix the perforated sound-absorbing metal plates.

[0014] By adopting the above technical solution, the rotating clips connected at the four corners of the enclosure frame provide a convenient and effective solution for fixing the perforated sound-absorbing metal plates, allowing construction workers to tighten or release the perforated sound-absorbing metal plates by simply rotating the rotating clips, thereby greatly simplifying the installation and disassembly process of the noise reduction plates and improving work efficiency.

[0015] It is further provided that the first moving mechanism includes a first mounting block, the bottom of the first mounting block is rotatably connected to a guide wheel, and first bolt holes are provided around the first mounting block.

[0016] By adopting the above technical solution, the first mounting block in the first moving mechanism provides a stable mounting platform for the guide wheel, so that the guide wheel can be firmly fixed to the bottom of the first noise reduction plate. The rotating connection of the guide wheel enables the noise reduction device to be easily moved on the ground at the construction site, reducing the resistance during movement and improving the flexibility and efficiency of movement.

[0017] It is further provided that the second moving mechanism includes a second mounting block, the bottom of the second mounting block is rotatably connected to a guide wheel, and the second mounting block is provided in a trapezoidal structure.

[0018] By adopting the above technical solution, the second mounting block in the second moving mechanism also provides a stable mounting platform for the guide wheel, and together with the first moving mechanism ensures that the noise reduction device can be easily and smoothly moved on the construction site.

[0019] It is further provided that two second moving mechanisms are provided, and a hook is provided between the two second moving mechanisms.

[0020] By adopting the above technical solution, two second moving mechanisms are provided, and a hook is provided between the two second moving mechanisms, thereby enhancing the stability and safety of the noise reduction device during movement and lifting.

[0021] It is further provided that one end of the second support rod is fixedly connected to a mounting plate, and a second bolt hole is provided on the mounting plate.

[0022] By adopting the above technical solution, the mounting plate fixedly connected to one end of the second support rod provides additional stability and supporting force for the fixation of the noise reduction device. When installing the noise reduction device, the mounting plate can be placed tightly on the already cast concrete pile or other fixed object, and then firmly fixed by passing the bolt through the second bolt hole, thereby ensuring that the noise reduction device will not shake or fall over during use.

[0023] Compared with related technologies, the detachable and movable construction site noise reduction device provided by the present invention has the following beneficial effects:

[0024] The utility model provides a detachable and movable noise reduction device for construction sites. By arranging a first noise reduction plate and a second noise reduction plate, the noise reduction device shows extremely high flexibility and adaptability when dealing with noise sources at different heights. When the noise source is located at a lower position, such as a steel bar processing shed, the noise reduction device can remain in a folded state and be easily pulled to the vicinity of the noise source by utilizing the guide wheels of the first moving mechanism and the second moving mechanism. Multiple noise reduction devices are arranged around it to effectively absorb most of the noise, providing a good working environment for the construction site. When the noise source is located at a higher position or the noise source needs to be completely blocked, the noise reduction device can easily pull up the second noise reduction plate through the cooperation of the crane and the hook, and combine it with the first noise reduction plate to form a complete noise reduction plate, which greatly increases the noise reduction area and effect, so that the noise reduction device can remain stable in various complex environments and continue to exert the noise reduction effect.

[0025] The utility model provides a detachable and movable noise reduction device for construction sites, which adopts a backboard, glass fiber sound-absorbing cotton and a perforated metal plate. The backboard, glass fiber sound-absorbing cotton and the perforated sound-absorbing metal plate are used to form a first noise reduction plate and a second noise reduction plate with sound absorption function. The device is placed around construction processing sheds, around concrete pump trucks, around construction production areas, etc., which can effectively control the spread of noise and reduce noise interference to residents near the construction site.

[0031] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the accompanying drawings, in which typical embodiments of the present invention are shown.

[0032] Example 1:

[0033] like Figure 1-4As shown, the utility model is a detachable and movable construction site noise reduction device, including a first noise reduction plate 1 and a second noise reduction plate 2. The tops of the first noise reduction plate 1 and the second noise reduction plate 2 are rotatably connected by a rotating shaft, the bottom of the first noise reduction plate 1 is fixedly connected to a first moving mechanism 6, and the bottom of the second noise reduction plate 2 is fixedly connected to a second moving mechanism 7. The first noise reduction plate 1 and the second noise reduction plate 2 are used to block the propagation of construction production noise at different heights. The first moving mechanism 6 connected to the bottom of the first noise reduction plate 1 and the second moving mechanism 7 connected to the bottom of the second noise reduction plate 2 are both equipped with guide wheels 602, so that the entire noise reduction device can be easily moved at the construction site.

[0034] like Figure 1 、 Figure 2 and Figure 3 As described, the back of the second noise reduction plate 2 is rotatably connected to the first support rod 3, one end of the first support rod 3 is rotatably connected to the second support rod 4, and the back of the first noise reduction plate 1 is fixedly connected to the clip 5, the clip 5 and the second support rod 4 are snap-connected. The snap-connection between the clip 5 fixedly connected to the back of the first noise reduction plate 1 and the second support rod 4 not only simplifies the installation and disassembly process of the support system, but also improves the stability and reliability of the noise reduction device.

[0035] like Figure 1 、 Figure 2 and Figure 3 The first moving mechanism 6 includes a first mounting block 601, the bottom of the first mounting block 601 is rotatably connected to a guide wheel 602, and first bolt holes 603 are opened around the first mounting block 601. The first bolt holes 603 opened around the first mounting block 601 provide a convenient way to fix the noise reduction device. At the construction site, in order to ensure the stability and safety of the noise reduction device, it is usually necessary to fix it to the ground. By using bolts to pass through the first bolt holes 603 and fix it to a cement trough or other fixed object on the ground, the noise reduction device can be firmly fixed to prevent it from moving or tipping over during use.

[0036] like Figure 1 、 Figure 2 and Figure 3 The second moving mechanism 7 includes a second mounting block 701, the bottom of which is rotatably connected to a guide wheel 602. The second mounting block 701 is arranged in a trapezoidal structure. The trapezoidal structure of the second mounting block 701 also takes into account the complex environment of the construction site. The trapezoidal structure provides greater structural strength, making it adaptable to the complex environment of the construction site.

[0037] like Figure 1 、 Figure 2 and Figure 3As described above, two second movable mechanisms 7 are provided, and a hook 9 is provided between the two second movable mechanisms 7. By hooking the hook 9 with a crane or other lifting equipment, the noise reduction device can be easily lifted, thereby improving construction efficiency.

[0038] like Figure 1 、 Figure 2 and Figure 3 As described, one end of the second support rod 4 is fixedly connected to a mounting plate 10, and a second bolt hole 11 is provided on the mounting plate 10. The second bolt hole 11 provided on the mounting plate 10 not only simplifies the fixing process of the noise reduction device, but also improves the flexibility and adaptability of the fixing, ensuring that the noise reduction device can be firmly fixed on the fixed object.

[0039] During implementation: First, the first noise reduction plate 1 and the second noise reduction plate 2 are towed by a trailer. At this time, the first noise reduction plate 1 and the second noise reduction plate 2 are in a folded state to form a stable mobile mechanism. The guide wheels 602 of the first mobile mechanism 6 and the second mobile mechanism 7 are in contact with the ground and are pulled to a low noise source, such as a steel bar processing shed. At this time, multiple noise reduction devices surround the noise source. Although they are slightly lower than the height of the steel bar processing shed, they can still absorb most of the noise.

[0040] When the noise source is at a higher position, such as a large pump truck or cement mixer truck, or when the steel bar processing shed needs to be completely shielded, after releasing the lock, pull the first noise reduction plate 1 and the second noise reduction plate 2 to the position, connect the hook 9 to the crane, start the crane to pull up one end of the second noise reduction plate 2 so that it can rotate around the rotating axis and combine with the first noise reduction plate 1 to form a complete noise reduction plate, then remove the second support rod 4 from the clamp 5, and fix it to the nearby cast concrete pile by bolting through the second bolt hole 11 to form a reliable support for the second noise reduction plate 2, and at the same time fix it to the cement trough on the ground with bolts through the first bolt hole 603 to form a stable support.

[0041] Example 2:

[0042] like Figure 4As shown, on the basis of embodiment 1, the utility model provides a technical solution: the first noise reduction plate 1 and the second noise reduction plate 2 both include an enclosure frame body 801, and the interior of the enclosure frame body 801 is sequentially provided with a backboard 805, glass fiber sound-absorbing cotton 802, a steel wire mesh 803 and a perforated sound-absorbing metal plate 804. The backboard 805, glass fiber sound-absorbing cotton 802, steel wire mesh 803 and perforated sound-absorbing metal plate 804 sequentially arranged inside the enclosure frame body 801 constitute a multi-layer sound-absorbing structure, and the backboard 805 serves as a base layer to provide a stable support for the sound-absorbing material; the glass fiber sound-absorbing cotton 802 has good sound absorption and heat insulation properties and can absorb most of the noise; the steel wire mesh 803 enhances the integrity and durability of the sound-absorbing structure; the perforated sound-absorbing metal plate 804, as the outermost layer, not only has an excellent sound absorption effect, but also can effectively reflect part of the noise, thereby further improving the noise reduction efficiency.

[0043] like Figure 4 As mentioned above, the enclosure frame 801 is pivotally connected to the four corners with swivel clips 12, which are used to secure the perforated sound-absorbing metal plates 804. The swivel connection of swivel clips 12 also enhances the flexibility and adaptability of the noise reduction panel structure. On construction sites, due to the complex and ever-changing environment, the perforated sound-absorbing metal plates 804 may become damaged and require frequent replacement. The use of swivel clips 12 allows the perforated sound-absorbing metal plates 804 to easily adapt to these changes without being damaged or deformed due to overly rigid fixing methods.

[0044] During implementation: First, a backboard 805 is fixed on the enclosure frame 801 with the guide wheel 602, and then the glass fiber sound-absorbing cotton 802 is fixed on the backboard 805 using the wire mesh 803, and a perforated sound-absorbing metal plate 804 is laid on the surface to form a sound insulation enclosure unit that absorbs noise and prevents the spread of noise. Multiple enclosure units are connected through connecting mechanisms, such as angle steel, connecting plates, etc. to form a noise reduction enclosure, which can be set up in the production and processing area of ​​the construction site, effectively controlling the spread of noise in the production and processing area of ​​the construction site, and reducing the noise interference to residents near the construction site.

[0045] The advantages of this technical solution in practical applications include but are not limited to the following:

[0046] 1. The second noise reduction plate is combined with the first noise reduction plate to form a complete noise reduction plate, which greatly increases the noise reduction area and effect, so that the noise reduction device can remain stable in various complex environments and continue to exert noise reduction effects;

[0047] 2. The backboard, glass fiber sound-absorbing cotton, and perforated sound-absorbing metal plate are used to form the first noise reduction board and the second noise reduction board with sound-absorbing function, which can effectively control the spread of noise.

[0048] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
