Description

Technical Field

[0001] The utility model relates to the technical field of highway sound insulation barriers, and particularly relates to a highway sound insulation barrier with an anti-collision structure. Background Technique

[0002] A highway refers to a public road that can be traveled by automobiles between cities, between urban and rural areas, and between rural areas, which has been accepted and recognized by the transportation competent department. Some highways pass through villages. Therefore, during the construction and use of these highways, sound insulation facilities are installed on both sides of the highways to reduce the spread of noise during construction and use, thereby reducing the impact on residents.

[0003] The Chinese utility model patent with the reference authorization publication number of CN221421727U discloses a highway sound insulation barrier, which relates to the technical field related to highway sound insulation barriers. It includes a mounting plate. Fixed blocks are fixedly installed at both ends of both sides of the mounting plate. Expansion bolts are installed on the fixed blocks. A counterweight box is fixedly installed at the upper end of the mounting plate. A counterweight block is slidably installed in the counterweight box. A sealing cover is installed at one end of the counterweight box. A buffer assembly is fixedly installed on one side of the counterweight box. An installation frame is fixedly installed at the upper end of the counterweight box. An installation slot is opened on one side of the installation frame. A sound insulation board is slidably installed in the installation slot. A limiting assembly is fixedly installed evenly on one side of the installation frame. By sliding the counterweight block into the counterweight box in a clamped manner, it is convenient for users to take out the counterweight block. At the same time, the sound insulation board is fixed in the installation frame through the limiting assembly. Pulling the limiting assembly can disassemble and assemble the sound insulation board, with simple operation and short time consumption.

Detailed Embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment 1: Please refer to Figures 1 - 4 and Figure 6 , for the existing highway sound insulation barrier, since the highway sound insulation barrier is installed on both sides of the highway, when an accident occurs, it is not convenient to add a buffer with an anti-collision structure. To solve this technical problem, the following technical content is disclosed in this embodiment;

[0026] An anti-collision device 4 is installed on the front side of the counterweight block 2, and the anti-collision device 4 is composed of a vertical plate 401, a square box 402, a moving box 403, a spring 404 and an anti-collision plate 405. Bolts are threadedly connected to the four corners of the vertical plate 401, and the bolts at the four corners of the vertical plate 401 fixedly connect the vertical plate 401 to the counterweight block 2. And square boxes 402 are fixedly connected to both the upper and lower ends of the front side of the vertical plate 401. A moving box 403 is slidably connected to the inner part of the front side of the square box 402, and a spring 404 is fixedly connected to the inner front side of the moving box 403. And the rear side of the spring 404 is fixedly connected to the inner rear side surface of the square box 402. An anti-collision plate 405 is fixedly connected to the front side of the moving box 403. An outer frame 7 is fixedly connected to the upper surface of the counterweight block 2 by bolts, and a buffer pad 12 is fixedly connected to the outer end of the front side surface of the outer frame 7;

[0027] The side of the counterweight block 2 where the anti-collision device 4 is installed on the front side faces the road. After the anti-collision plate 405 in the anti-collision device 4 is squeezed, the anti-collision plate 405 will drive the moving box 403 to move inward. Since the inside of the moving box 403 is slid in the square box 402 by the spring 404, the spring 404 will drive the moving box 403 to rebound forward, preventing the counterweight block 2 and the sound insulation board body 11 from being hit;

[0028] Embodiment Two: For the existing sound insulation barrier for roads, the sound insulation barriers beside the road are composed of a single barrier arranged side by side in a row, and it is not convenient to connect and fix the combined sound insulation barriers. Therefore, through the following technical solutions in this embodiment, as Figures 1 - 5 shown;

[0029] A placement groove 3 is opened in the middle of the upper surface of the counterweight block 2, and an outer frame 7 is fixedly connected to the upper side of the counterweight block 2 by bolts. And a connection groove 8 is opened at the upper right end of the outer frame 7, a groove 9 is opened at the upper left end of the outer frame 7, and an I-shaped plate 10 is fixedly connected to the left side of the groove 9 by bolts. A sound insulation board body 11 is fixedly connected to the inner side of the outer frame 7. Connecting plates 5 are fixedly connected to both the left and right sides at the rear end of the upper surface of the installation base plate 1, and a connection through hole 6 is opened in the middle of the connecting plate 5;

[0030] The sound insulation barriers on both sides of the road are composed of a plurality of separate sound insulation barriers spliced together. When splicing two sound insulation barriers, slide the I-shaped plate 10 on one sound insulation barrier into the connection groove 8 of the other sound insulation barrier. The bottom counterweight block 2 and the installation base plate 1 are fixed by the connecting plates 5 connecting the bottoms of the two sound insulation barriers. On the left side of the outer frame 7 of the leftmost sound insulation barrier, the I-shaped plate 10 can be removed and a rectangular plate member matching the groove 9 can be fixedly connected by bolts, so that the left side surface of the outer frame 7 of the leftmost sound insulation barrier is a flat plane. In the connection groove 8 on the right side of the outer frame 7 of the rightmost sound insulation barrier, a T-shaped plate member matching the connection groove 8 can be inserted, so that the combined sound insulation barriers can be connected and fixed together;

[0031] Embodiment 3: For the existing sound insulation barrier for roads, it is not convenient to disassemble and assemble the sound insulation barrier during maintenance. Therefore, this embodiment adopts the following technical solutions, as Figures 1 - 5 shown;

[0032] Threaded holes are provided at the four corners of the installation base plate 1, and stabilizing bolts are threadedly connected in the threaded holes provided at the four corners of the installation base plate 1. Moreover, the bottom of the stabilizing bolts is fixedly connected to the ground. The middle part of the upper surface of the installation base plate 1 is fixedly connected with a counterweight 2.

Engage the convex block 13 on the lower surface of the outer frame 7 into the placement groove 3. The outer frame 7 and the sound insulation board body 11 can be positioned on the counterweight 2 first, and then fix the outer frame 7 to the upper surface of the counterweight 2 by the bolts at the four corners of the bottom of the outer frame 7. The large main structures of the sound insulation barrier can be disassembled and assembled.
