Description
Technical Field
[0001] This utility model relates to the field of sound barrier maintenance technology, specifically to an efficient sound-absorbing and noise-reducing auxiliary structure for the maintenance of urban elevated sound barriers. Background Technology
[0002] Elevated noise barriers in cities are important facilities for reducing traffic noise and improving the quality of the surrounding sound environment. Elevated noise barriers are generally installed on the side wing beam piers. The elevated noise barrier consists of a U-shaped frame and sound insulation panels inserted inside the U-shaped frame. Sound insulation glass is also embedded in the sound insulation panel in the middle position to facilitate visibility and allow for a wider field of vision.
[0003] After the elevated road section is completed, sound barrier components will be installed on the side beam piers to reduce noise. Traditional sound barrier installation requires the use of cranes to lift the sound barriers, but cranes occupy a large area and affect the movement of construction vehicles. Of course, scaffolding will also be erected, which occupies a small area, but the sound barriers need to be lifted up manually for installation, which is inefficient. Utility Model Content

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.
[0024] Please see Figure 1-6 The maintenance auxiliary structure for the high-efficiency sound absorption and noise reduction urban elevated sound barrier includes an elevated bridge 1, a side wing beam pier 2 fixedly installed on the top of the elevated bridge 1, an elevated sound barrier assembly 3 fixedly installed on the top of the side wing beam pier 2, the elevated sound barrier assembly 3 is composed of a U-shaped frame and multiple sound insulation panels 21 inserted in the U-shaped frame, and a maintenance auxiliary structure is provided on the side of the side wing beam pier 2, which can be used to hoist, move and assemble the sound insulation panels 21.
[0025] Please see Figure 1-6The maintenance auxiliary structure includes a movable base 4, with movable wheels 5 movably installed at the bottom of the movable base 4. The movable wheels 5 can be used to move the entire maintenance auxiliary structure. Alternatively, the movable wheels 5 can be replaced with an electric drive. A step platform 6 is fixedly installed on the top of the movable base 4, and a vertical ladder 11 is fixedly installed on the top of the step platform 6. When the sound insulation panel 21 is difficult to splice with the U-shaped frame, personnel can climb to the location of the hoisted sound insulation panel 21 via the step platform 6 and the vertical ladder 11, and manually control the sound insulation panel 21 to align with the U-shaped frame. A top frame 12 is fixedly installed on the top of the vertical ladder 11, and two symmetrically arranged guide rails 13 are fixedly installed on the top of the top frame 12. A slider 14 is slidably installed on the outer side of the guide rails 13, and a mounting plate 15 is fixedly installed on the top of the slider 14. The mounting plate 15 moves along the direction of the guide rails 13 via the slider 14 to ensure that there is no jamming when moving.
[0026] Please see Figure 1-6 A shaft 16 is rotatably mounted inside the mounting plate 15. One end of the shaft 16 is fixedly mounted to the output end of the motor reducer 17. Two symmetrically arranged reels 18 are fixedly mounted on the outer side of the shaft 16. A rope 19 is wound around the outer side of the reels 18, and a sound insulation plate 21 is connected to the bottom of the rope 19 via an elastic band 20. The motor reducer 17 drives the shaft 16 and the reels 18 to rotate, causing the reels 18 to wind the rope 19, thereby lifting the sound insulation plate 21.
[0027] Please see Figure 1-3 A side plate 9 is fixedly installed between the two stepped platforms 6. The side plate 9 facilitates the support and leaning of the sound insulation panel 21 that has not been lifted. A partition strip 10 is fixedly installed on the side of the side plate 9. Both the side plate 9 and the partition strip 10 are fixedly installed on the surface of the movable base 4. The sound insulation panel 21 is placed on the partition strip 10 to ensure that there is a gap at the bottom of the sound insulation panel 21, which facilitates the fitting of the elastic band 20. A frame 7 is fixedly installed on the side of the stepped platform 6. A counterweight 8 is set inside the frame 7 to ensure the stability of the movable base 4, lower the center of the maintenance auxiliary structure as a whole, and prevent it from tipping over.
[0028] Please see Figure 5-6 A central support 22 is rotatably mounted in the middle of the shaft 16. A lead screw sleeve 23 is embedded below the central support 22. A lead screw shaft 24 is rotatably mounted inside the lead screw sleeve 23. The lead screw shaft 24 is rotatably connected to the inner wall of the top frame 12. One end of the lead screw shaft 24 is fixedly mounted to the output end of the motor reducer 25. Two symmetrically arranged slide rods 26 are slidably inserted inside the central support 22. The slide rods 26 are fixedly mounted to the inner wall of the top frame 12. The lead screw shaft 24 and the two slide rods 26 form a triangular arrangement. The motor reducer 25 drives the lead screw shaft 24 to rotate, and then the central support 22 slides along the direction of the slide rods 26.
[0029] Please see Figure 5-6 Motor reducer 17 is fixedly installed on mounting plate 15, and motor reducer 25 is fixedly installed on the outer wall of top frame 12. Motor reducer 17 and motor reducer 25 are connected to the PLC controller via signal. Motor reducer 17, motor reducer 25 and PLC controller are all references to existing technology, which will not be described in detail in this application. When using them, the preferred option can be selected under the premise of meeting the driving conditions.
[0030] Working principle: When in use, the sound insulation board 21 is placed on the partition strip 10, and the elastic band 20 is fitted on both ends of the sound insulation board 21. The motor reducer 17 drives the shaft 16 and the reel 18 to rotate. The reel 18 winds the rope 19, and then the sound insulation board 21 will slowly rise until the position of the sound insulation board 21 exceeds the position above the elevated sound barrier assembly 3 and then stops.
[0031] The motor reducer 25 drives the lead screw shaft 24 to rotate, and the lead screw shaft 24 drives the central support 22 to move along the slide bar 26. Then the sound insulation plate 21 will also move forward until the position of the sound insulation plate 21 is exactly above the sound insulation screen frame and then stops.
[0032] Then, the motor reducer 17 drives the shaft 16 and the reel 18 to rotate in opposite directions. The reel 18 loosens the rope 19, and the sound insulation panel 21 will slowly fall into the sound insulation screen frame, thereby realizing the rapid installation of the sound insulation panel 21 and improving the installation efficiency.
[0033] During the descent of the soundproof panel 21, personnel can also climb to the top of the U-shaped frame via the vertical ladder 11, making it convenient for people to align the soundproof panel 21 with the U-shaped frame and insert it.
[0034] By placing a counterweight 8 on the movable base 4, the center of the entire maintenance auxiliary structure is lowered, ensuring that it will not tip over. The entire maintenance auxiliary structure can be moved by the movable wheels 5 at the bottom of the movable base 4, which makes it convenient to move the entire maintenance auxiliary structure to the next installation position after the sound insulation panel 21 is installed. The maintenance auxiliary structure of this application is easy to use, occupies a small area, and will not affect the driving of other vehicles.
[0035] 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.
