Description

Technical Field

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

[0002] Municipal road construction noise reduction refers to taking a series of measures to reduce the impact of noise caused by construction activities on the surrounding environment and residents' lives during construction work such as urban road construction, maintenance or renovation.

[0003] Among them, announcement number CN220377567U discloses a noise reduction device for road construction, including a device base, storage slots are provided on both sides of the device base, and fixed brackets are movably installed on the front and rear surfaces of the storage slots, respectively, and a noise reduction plate is fixedly installed on the upper surface of the device base, and a ventilation frame is fixedly installed on the side surface of the noise reduction plate. The utility model is a noise reduction device for road construction. During road construction, the noise reduction device is convenient to move and install. The stability of the noise reduction device is improved by fixing the bracket and the pointed fixing long bolt to prevent the noise reduction device from moving and tipping. The inclined sound-absorbing board and the sound insulation cotton cooperate with the noise reduction board to refract the noise transmission angle and multiple absorption and blocking, thereby increasing the attenuation speed of the sound during transmission and improving the noise reduction effect. The ventilation frame and the wind wheel cooperate to open up a ventilation space while reducing noise, thereby preventing strong wind from blowing to the noise reduction device and improving the wind resistance of the noise reduction device.

[0004] Although this device effectively improves the stability of the noise reduction device, since the noise reduction plate is a whole and usually has a high height, it is extremely inconvenient during installation and transportation, resulting in low installation efficiency and thus reduced road construction efficiency.

[0005] Therefore, it is necessary to invent a road construction noise reduction device to solve the above problems. Utility Model Content

[0013] By adopting the above technical solution, the third positioning column slides inside the second positioning groove to position the third noise reduction plate.

[0014] Optionally, connection holes are formed at a position close to the upper end of the first positioning column, at a position close to the upper and lower ends of the second positioning column, and at a position close to the lower end of the third positioning column, and latches are inserted into the connection holes.

[0015] By adopting the above technical solution, after all three groups of noise reduction plates are unfolded, the pin is inserted into the connecting hole at the upper end of the first positioning column and the connecting hole at the lower end of the second positioning column to fix the first noise reduction plate and the second noise reduction plate, and the connecting hole at the upper end of the second positioning column and the connecting hole at the lower end of the third positioning column to fix the second noise reduction plate and the third noise reduction plate.

[0017] By adopting the above technical solution, during the process of splicing the left and right noise reduction mechanisms, the plug-in rod in the right noise reduction mechanism is inserted into the connecting block in the left noise reduction mechanism to splice and fix the left and right noise reduction mechanisms.

[0018] Optionally, two groups of fixed blocks are fixedly connected to the front surface of the first noise reduction plate on the rear side, a rotating block is slidably connected inside the fixed block, a first support rod is fixedly connected to the lower end of the rotating block, and a second support rod is slidably connected inside the first support rod.

[0019] Optionally, a locking screw is threadedly connected to the surface of the first support rod near the lower end, and the bottom end of the locking screw is tightly against the surface of the second support rod.

[0020] By adopting the above technical solution, after the noise reduction mechanism is installed, the first support rod is rotated outward, and then the second support rod is pulled outward to support the noise reduction mechanism, thereby improving the stability of the noise reduction mechanism.

[0021] In the above technical solution, the technical effects and advantages provided by the utility model are:
