[0002] Construction project management is to plan, organize and control the project during the construction process of a construction project to ensure the project quality, safety and progress. During the construction process, the operation of mechanical equipment, material handling, etc. will generate relatively large noise, which will interfere with the life and rest of the surrounding residents. Therefore, it is necessary to carry out noise reduction treatment on the construction area.

[0003] The publication number is CN221096098U, which provides an environment-friendly noise reduction device for construction project management, including a first noise reduction net plate. A second noise reduction net plate is arranged on one side of the first noise reduction net plate. Connecting pieces are arranged between the first noise reduction net plate and the second noise reduction net plate.

[0004] The above-mentioned environment-friendly noise reduction device has the effect of being able to clean the dust adhering to the noise reduction holes on the surface of the noise reduction net plate. Due to the limited noise reduction height, the noise in the construction area can spread outward from a higher place, which is not convenient to adjust the noise reduction height, and the contact area between the base and the ground is small, resulting in poor overall stability.

[0027] The lifting frame 5 is located at the front part of the fixed frame 1 and is arranged to slide up and down. The screw rod 9 passes through the inside of the lifting frame 5 and is arranged to be threadedly connected.

[0028] The rotating rod 8 is located inside the bottom box 7 and is arranged to rotate movably. The bevel gears 10 at both ends of the rotating rod 8 and the bevel gears 10 at the bottom end of the screw rod 9 are arranged to be meshed with each other.

[0029] The worm 12 passes through the inside of the bottom box 7 and is arranged to rotate movably. The worm 12 and the worm gear 13 are arranged to be meshed with each other.

[0030] Specifically, the motor 11 is driven to rotate the worm 12, so that the worm gear 13 drives the rotating rod 8 to rotate. Through the meshing of the bevel gears 10, the two screw rods 9 rotate simultaneously. Through the threaded connection between the screw rod 9 and the lifting frame 5, the lifting frame 5 is driven to slide up and down. Through the first noise reduction plate 2 and the second noise reduction plate 6, the noise reduction height is increased, which is convenient for the storage of the second noise reduction plate 6.

[0031] Embodiment Two

[0032] Refer to Figure 4 and Figure 5 On the basis of Embodiment One, it is further obtained that the positioning component 4 includes a base 14 and a clamping plate 15. The clamping plate 15 is fixedly installed at the bottom of the bottom box 7. A clamping groove 16 is formed at the top of the base 14. Positioning holes 17 are formed at both ends of the front part of the clamping plate 15. Positioning bolts 18 are movably installed on both sides of the front part of the base 14. Two support plates 19 are movably installed at both ends of the bottom of the base 14. Fixing holes 20 are formed at the top of the support plates 19. Two contraction grooves 21 are formed at both ends of the bottom of the base 14. A shaft rod 22 is fixedly installed at the inner end of the support plate 19. Fixed shafts 23 are installed at both ends of the shaft rod 22. The fixed shafts 23 and the base 14 are fixed to each other. A spring 24 is installed inside the fixed shaft 23.

[0033] The clamping plate 15 and the clamping groove 16 are arranged to be clamped. The positioning bolt 18 passes through the front part of the base 14 and is arranged to be threadedly connected. The inner end of the positioning bolt 18 and the positioning hole 17 are arranged to be clamped.

[0034] The support plate 19 and the base 14 are movably connected through the shaft rod 22. Both ends of the shaft rod 22 pass through the inside of the fixed shaft 23 and are arranged to rotate movably. Both ends of the spring 24 are fixedly connected to the shaft rod 22 and the inner wall of the fixed shaft 23 respectively.

[0035] Specifically, by inserting the clamping plate 15 into the clamping groove 16, the positioning bolt 18 slides backward under the action of the thread and is inserted into the positioning hole 17, facilitating the installation between the fixing frame 1 and the base 14. By unfolding the four support plates 19, the fixing holes 20 are used for the connection between the bolts and the ground, increasing the contact area between the base 14 and the ground and improving the overall stability. The support plates 19 automatically rotate and contract into the contraction groove 21 under the action of the spring 24 and can be automatically stored after disassembly.

[0036] During the actual operation process, by inserting the clamping plate 15 into the clamping groove 16, the fixing frame 1 and the base 14 are fixed to each other, and the noise in the construction area is absorbed and reduced by the first noise reduction plate 2 and the second noise reduction plate 6;

[0037] When the second noise reduction plate 6 is unfolded or stored, by connecting the motor 11 to the power supply, the motor 11 drives the worm 12 to rotate, causing the worm gear 13 to drive the rotating rod 8 to rotate. Under the meshing action of the bevel gears 10, the two screw rods 9 are driven to rotate simultaneously, and then the lifting frame 5 is driven to slide upward, raising the second noise reduction plate 6 and increasing the height of noise reduction. By sliding the lifting frame 5 downward to the front part of the fixing frame 1, the lifting frame 5 and the fixing frame 1 are overlapped for overall storage;

[0038] When disassembling, installing, and fixing, unfold the four support plates 19, insert the bolts into the fixing holes 20 to connect and fix with the ground, and at the same time increase the contact area between the base 14 and the ground. Then insert the clamping plate 15 into the clamping groove 16, and by rotating the positioning bolt 18, the positioning bolt 18 is inserted into the positioning hole 17, thereby fixing the clamping plate 15. When disassembling, take out the clamping plate 15 from the clamping groove 16, the support plates 19 are separated from the ground, and the shaft rod 22 drives the support plates 19 to automatically rotate into the contraction groove 21 under the action of the spring 24 to store the support plates 19, reducing the scratching of external objects during transportation and storage.
