[0025] In some embodiments, the portal frame 3 includes a movable plate 31, which is slidably connected to the ground guide rail 2. A dovetail groove may be provided at the bottom of the movable plate 31, in which the ground guide rail 2 is inserted, so as to facilitate the movement of the movable plate 31 on the ground guide rail 2 and increase the contact area between the movable plate 31 and the ground guide rail 2, thereby enhancing the pressure-bearing strength of the movable plate 31; a U-shaped rod 32 is connected between the two movable plates 31, and a lifting device 4 is provided on the top of the U-shaped rod 32. The lifting device 4 includes a lifting part 41, which may be an electric hoist. This is a prior art and will not be described in detail here; the lifting part 41 is fixedly mounted on the top of the portal frame 3, and a lifting frame 42 is provided at the bottom of the lifting part 41. The lifting frame 42 may be a long tripod. The lifting frame 42 forms multiple lifting points between the lifting part 41 and the sound absorbing panel 8, thereby improving the stability of the sound absorbing panel 8 during lifting, thereby improving the installation quality of the sound absorbing panel 8.

[0026] In some embodiments, two reinforcing rods 33 are symmetrically provided between the U-shaped rod 32 and the movable plate 31, which can strengthen the connection strength between the U-shaped rod 32 and the movable plate 31, improve the stability of the lifting device 4 on the U-shaped rod 32, and thus improve the stability of the lifting process.

[0027] In some embodiments, the portal frame 3 and the steel column 1 are detachably connected, and the U-shaped rod 32 and the steel column 1 can be connected by a steel cable 7. Through the connection of the steel cable 7, the connection points between the U-shaped rod 32 and the steel column 1 are increased, thereby increasing the force points between the two, thereby enhancing the stability of the U-shaped rod 32. At the same time, the steel cable 7 is easy to disassemble, reducing the impact on the movement of the portal frame 3.

[0028] In some embodiments, the longitudinal moving beam 5 can be an I-beam, which is convenient for material acquisition and can meet the use requirements of the longitudinal moving device 6. The longitudinal moving device 6 can be a longitudinal moving electric hoist, which can drive the pulley in the longitudinal moving beam 5 to roll by the rotation of the moving motor, thereby realizing the movement of the sound-absorbing plate 8 under the lifting of the longitudinal moving device 6. The longitudinal moving electric hoist is a prior art, and the specific structure and principle will not be repeated here.

[0029] In some embodiments, a connecting plate is vertically provided on one side of the steel column 1, and a longitudinal beam 5 is provided between the multiple connecting plates. By connecting the connecting plates, the vertical distance between the steel column 1 and the longitudinal beam 5 can be increased to avoid the distance between the two being too close to affect the movement of the longitudinal device 6 on the longitudinal beam 5.

[0030] The specific working principle is as follows:

[0031] In actual construction, the sundries on the surface where the steel column 1 is located are cleared, the foundation is dredged, and the foundation is reinforced and compacted.

[0032] According to the design plan, the ground rails 2 are installed on the foundation at a certain spacing and angle.

[0033] Connect the two moving plates 31 through the U-shaped rod 32 to ensure that the connection between the U-shaped rod 32 and the moving plates 31 is firm and reliable. Install the moving plate 31 on the ground rail 2 so that the door frame 3 can slide along the ground rail 2. Install the lifting device 4 on the top of the door frame 3, move the door frame 3 to between the two steel columns 1 where the sound absorbing panel 8 is to be installed, and use the steel cable 7 to connect the door frame 3 and the two steel columns 1 to ensure the stability and continuity of the entire system.

[0034] A longitudinal shift beam 5 is installed on one side of the steel column 1. The longitudinal shift beam 5 can be an I-beam and is connected to multiple steel columns 1 through a connecting plate. A longitudinal shift device 6 is installed on the longitudinal shift beam 5 to complete the assembly of the entire installation system.

[0035] The sound absorbing panel 8 is fixed on the longitudinal moving device 6. One sound absorbing panel 8 can be fixed on two longitudinal moving devices 6 by a steel wire rope to ensure the stability of the movement of the sound absorbing panel 8. The sound absorbing panel 8 is driven to move longitudinally into place by the longitudinal moving device 6, and the hanging frame 42 is lowered to a suitable position by the hanging piece 41 of the hanging device 4, and then the sound absorbing panel 8 is fixed on the hanging frame 42. The hanging piece 41 drives the sound absorbing panel 8 to rise above the steel column 1, and the hanging piece 41 drives the sound absorbing panel 8 to be inserted between the two steel columns 1. After being inserted into place, the next sound absorbing panel 8 is installed until the installation of all the sound absorbing panels 8 between the two steel columns 1 is completed.

[0036] After the installation is completed, the steel cable 7 between the steel column 1 and the door frame 3 is removed, and the door frame 3 is moved to the next installation station, and the installation is completed according to the above steps.

[0037] The sound absorbing panels 8 are inserted between the steel columns 1 piece by piece from top to bottom. When inserting, be careful not to damage the single-tube rubber pad that separates the sound absorbing panels 8 and the steel columns 1. When inserting, insert both sides horizontally from top to bottom at the same time to avoid damaging the sound absorbing panels 8 when inserting at an angle. In some areas, if the gap between the sound absorbing panels 8 and the steel columns 1 is small and cannot be inserted, a rubber hammer can be used to tap and insert slowly to improve the installation quality.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
