When a noise barrier is damaged, the replacement process requires disassembling and reassembling a large number of bolts, which is time-consuming and affects the construction efficiency of municipal projects. Therefore, a high-efficiency noise reduction noise barrier structure for municipal construction is needed to solve the above problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a high-efficiency noise reduction municipal construction sound barrier structure, including a road box 1 and a sound insulation shell 3. The sound insulation shell 3 is detachably installed on the outer top wall of the road box 1. The sound insulation shell 3 has a hollow structure and a sound-absorbing panel 5 is provided inside the sound insulation shell 3. The sound insulation shell 3 is made of fiberglass and the sound-absorbing panel 5 is made of polyester fiber, so that the sound insulation shell 3 and the sound-absorbing panel 5 have a high sound insulation and noise reduction effect.

[0023] Vertical sleeves 7 are fixed to both sides of the top wall of the road box 1 located behind the soundproof shell 3. L-shaped reinforcing columns 6 are fixed to both sides of the rear end face of the soundproof shell 3. The vertical part of the reinforcing column 6 is movably inserted into the inner ring of the sleeve 7. A groove 14 is opened on the side of the two reinforcing columns 6 inside the road box 1 that are close to each other. L-shaped inner columns 11 are slidably connected to both sides of the inner top wall of the road box 1. A top sliding groove is opened on both sides of the inner top wall of the road box 1 along the length direction. The top of the inner column 11 is slidably connected to the top sliding groove through a top slider, so that the inner column 11 can move horizontally stably. The horizontal parts of the two inner columns 11 that are far apart are respectively movably set in the two grooves 14. Inside 4, a vertical stud 8 is rotatably connected to the middle of the road box 1 via a bearing. The top of the stud 8 is located on the upper side of the road box 1 and is fixed with a wheel handle 13. Rotating the wheel handle 13 can drive the stud 8 to rotate. The outer ring of the stud 8 inside the road box 1 is threaded with a vertical sleeve 9. Horizontal side rods 10 are fixed to the side ends of both sides of the vertical sleeve 9. Side sliding grooves are opened along the height direction on the inner side walls of both sides of the road box 1. The side ends of the side rods 10 are slidably connected to the side sliding grooves through side sliders, so that the vertical sleeve 9 and the side rods 10 can be raised and lowered stably. The top of the side rods 10 is hinged to an inclined coupling 12. The top of the coupling 12 is hinged to the bottom end of the inner column 11.

[0024] like Figures 1-3 As shown, fixing feet 4 are fixed on both sides of the front end face and both sides of the rear end face of the road box 1. The bottom of the fixing feet 4 is flush with the bottom of the road box 1. A round hole is opened in the middle of the fixing feet 4. The fixing feet 4 are stably fixed to the ground next to the municipal road by passing bolts through the round holes, so that the road box 1 can be stably fixed.

[0025] like Figures 1-3 As shown, both ends of the outer top wall of the road box 1 are fixed with U-shaped limiting frames 2. The inner dimensions of the limiting frames 2 are adapted to the dimensions of the sound insulation shell 3. The sound insulation shell 3 is movably installed inside the two limiting frames 2. The top of the limiting frames 2 is flush with the top of the sound insulation shell 3. The sound insulation shell 3 is inserted into the inner sides of the two limiting frames 2 to prevent the sound insulation shell 3 from shifting horizontally.

[0026] like Figures 3-4 As shown, the inner ring of the sleeve 7 is square, and the size of the inner ring of the sleeve 7 is adapted to the size of the reinforcing column 6. The two reinforcing columns 6 are respectively inserted into the inner rings of the two sleeves 7 to prevent the reinforcing column 6 and the sound insulation shell 3 from shifting horizontally. The bottom end of the horizontal part of the reinforcing column 6 contacts the top end of the sleeve 7 to prevent the sound insulation shell 3 from swinging back and forth. The size of the groove 14 is adapted to the size of the inner column 11. The two inner columns 11 are respectively inserted into the two grooves 14 to prevent the reinforcing column 6 and the sound insulation shell 3 from shifting vertically, and to achieve stable fixation of the reinforcing column 6 and the sound insulation shell 3.

[0027] like Figures 3-4As shown, the top ends of the two couplings 12 are respectively hinged to the bottom ends of the two inner columns 11. The two couplings 12 are arranged symmetrically in a figure-eight shape. When the stud 8 rotates clockwise, the vertical sleeve 9 can drive the side rod 10 to rise through the threaded transmission between the stud 8 and the vertical sleeve 9. The two side rods 10 drive the bottom ends of the two couplings 12 to rise, which can cause the top ends of the two couplings 12 to drive the two inner columns 11 to move closer to each other. When the stud 8 rotates counterclockwise, the vertical sleeve 9 can drive the side rod 10 to fall. The two side rods 10 drive the bottom ends of the two couplings 12 to fall, which can cause the top ends of the two couplings 12 to drive the two inner columns 11 to move away from each other.

[0028] In this invention, when disassembling the sound barrier, rotating the wheel handle 13 clockwise causes the stud 8 to rotate, which in turn causes the vertical sleeve 9 to lift the side rods 10. The two side rods 10 then lift the bottom ends of the two couplings 12, causing the top ends of the two couplings 12 to move the two inner columns 11 closer together until the inner columns 11 disengage from the groove 14. Then, lifting the sound insulation shell 3 allows the reinforcing column 6 to disengage from the sleeve 7, until the sound insulation shell 3 disengages from the limiting frame 2, thus completing the disassembly of the sound barrier. If installation is required, inserting the sound insulation shell 3 into the inner side of the two limiting frames 2 allows the vertical part of the reinforcing column 6 to insert into the inner ring of the sleeve 7 until the bottom end of the sound insulation shell 3 contacts the top end of the road box 1, thus allowing the horizontal part of the reinforcing column 6 to be installed. The bottom end of the sleeve 7 contacts the top end of the sleeve 7. At this time, the two inner columns 11 are located between the two reinforcing columns 6. Then, by rotating the wheel handle 13 counterclockwise, the stud 8 is rotated, which causes the vertical sleeve 9 to drive the side rod 10 to descend. The two side rods 10 drive the bottom ends of the two couplings 12 to descend, which causes the top ends of the two couplings 12 to drive the two inner columns 11 to move away from each other until the two inner columns 11 are respectively inserted into the interior of the two grooves 14. This can stably fix the reinforcing column 6 and the sound insulation shell 3, thus completing the installation of the sound barrier. There is no need to install and fix the sound barrier with a large number of bolts. When the sound barrier is damaged, there is no need to disassemble and install a large number of bolts during the replacement process. The replacement process of the sound barrier is less time-consuming and helps to improve the construction efficiency of municipal construction.

[0029] The soundproof shell 3 with a hollow structure is used as the outer shell of the soundproof barrier, and the soundproof shell 3 is filled with a sound-absorbing panel 5 made of polyester fiber material, which makes the soundproof barrier have a high sound insulation and noise reduction effect.

[0030] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
