Description

Technical Field

[0001] The utility model relates to the road, bridge and municipal engineering field, in particular to a road, bridge and municipal engineering sound insulation barrier. Background Art

[0002] Road and bridge municipal noise barriers are a type of sound insulation facility designed specifically for roads, bridges and municipal environments, aiming to reduce the impact of traffic noise on the surrounding environment and residents. It is usually installed beside major traffic routes such as roads, bridges, and highways to block, reflect or absorb noise, thereby reducing the spread and interference of noise.

[0003] Existing sound barriers are mostly made of one-piece sound insulation boards. However, the one-piece sound insulation boards are large in size and inconvenient to install. When loaded and transported, the one-piece sound insulation boards occupy a large space, which reduces the carrying capacity of a single transport vehicle. In addition, sound insulation boards of different heights are required in different scenarios, which makes it impossible to use the same sound insulation board in different scenarios.

[0007] The driven bevel gear is located in the middle of the bidirectional screw rod, the driving bevel gear is located inside the main body, and the outer wall of the driven bevel gear is meshed with the outer wall of the driving bevel gear.

[0008] As a further description of the above technical solution:

[0009] The front and rear inner walls of the main body are both provided with limiting grooves, and the number of the limiting grooves is two respectively. The front and rear outer walls of the lifting plate are both fixedly connected with limiting blocks, and the number of the limiting blocks is two respectively. The limiting blocks are located inside the limiting grooves.

[0010] As a further description of the above technical solution:

[0011] A connecting groove is provided on the right outer wall of the lifting plate, and a connecting plate is fixedly connected to the left outer wall of the lifting plate.

[0012] As a further description of the above technical solution:

[0013] A positioning groove is provided at the bottom of the right outer wall of the main body, and a pull plate groove is provided on the front outer wall of the main body. The pull plate groove is connected with the positioning groove through a connecting groove. A spring is fixedly connected to the inner wall of the pull plate groove, and there are multiple springs. A pull plate is installed on the inner wall of the pull plate groove, and the other ends of the multiple springs are fixedly connected to the inner wall of the pull plate. A handle is fixedly connected to the outer wall of the pull plate, and a locking block is fixedly connected to the inner wall of the pull plate.

[0014] As a further description of the above technical solution:

[0015] The right outer wall of the main body is provided with two slots, and the left outer wall of the main body is fixedly connected with two plugging plates.

[0016] The utility model has the following beneficial effects:

[0017] 1. By setting a turntable, in the initial state, the lifting plate is retracted in the main body. At this time, the sound insulation barrier occupies a small space. During transportation, the number of bicycles carried is increased, and the two moving blocks are in a state of being close to each other. Then, the turntable is rotated to drive the driven bevel gear to rotate. Since the driven bevel gear is meshed with the driving bevel gear, the driven bevel gear and the driving bevel gear rotate synchronously, so that the two moving blocks move back to back. When the two moving blocks and the moving U-shaped plate connected to the top move back to back together, the bottoms of the two linkage rods move back to back with the two moving U-shaped plates, and the other ends of the two linkage rods lift the two lifting U-shaped plates and the lifting plate upward, so that the lifting plate is moved out from the top of the main body. It can be used according to different usage scenarios. The sound barrier can be applied to a variety of scenes by adjusting the height of the lifting plate, which greatly improves the applicability of the sound barrier. The existing sound barriers are mostly spliced ​​with one-piece sound insulation boards, but the one-piece sound insulation boards are large in size and inconvenient to install. When loaded and transported, the one-piece sound insulation boards occupy a large space, which reduces the carrying capacity of a single transport vehicle. In addition, sound insulation boards of different heights are required in different scenes, which makes it impossible to use the same sound insulation board in different scenes. When the sound barrier is not in use, it occupies space. At the same time, the height of the lifting plate can be adjusted according to different usage scenarios, so that the sound barrier can be applied to a variety of scenes, which greatly improves the applicability of the sound barrier.

[0018] 2. Two limit grooves are respectively provided on the front and rear inner walls of the main body. During the lifting process of the lifting plate, the two limit blocks respectively connected to the front and rear outer walls move along the limit grooves, making the lifting process of the lifting plate more stable. When the left and right main bodies are spliced, the positioning block connected to the left outer wall of the right main body is inserted into the positioning groove provided on the right outer wall of the left main body. In this process, the positioning block on the left side of the right main body pushes the locking block in the positioning groove on the right side of the left main body toward the outside of the left main body. At this time, the spring inside the left main body is in a compressed state. After the positioning block on the right side connected to the right main body completely enters the positioning groove provided on the right side of the left main body, the multiple springs in the left main body rebound, so that the locking block in the positioning groove provided on the left main body returns to its position, thereby locking and connecting the two main bodies for easy splicing.

[0029] Rotating the turntable 12 drives the driven bevel gear 9 to rotate. Since the driven bevel gear 9 is meshed with the driving bevel gear 10, the driven bevel gear 9 and the driving bevel gear 10 rotate synchronously, thereby causing the two moving blocks 4 to move away from each other. When the two moving blocks 4 and the moving U-shaped plate 5 connected to the top move away from each other, the bottom of the two linkage rods 6 moves away from each other with the two moving U-shaped plates 5, and the other ends of the two linkage rods 6 lift the two lifting U-shaped plates 8 and the lifting plate 7 upwards, thereby moving the lifting plate 7 out from the top of the main body 1. The height of the lifting plate 7 can be adjusted according to different usage scenarios.

[0030] The driven bevel gear 9 is located in the middle of the bidirectional screw 3, the driving bevel gear 10 is located inside the main body 1, the outer wall of the driven bevel gear 9 is meshed with the outer wall of the driving bevel gear 10, the front and rear inner walls of the main body 1 are provided with limiting grooves 13, and the number of limiting grooves 13 is two, the front and rear outer walls of the lifting plate 7 are fixedly connected with limiting blocks 14, and the number of limiting blocks 14 is two, the limiting blocks 14 are located inside the limiting grooves 13, the right outer wall of the lifting plate 7 is provided with a connecting groove 15, and the left outer wall of the lifting plate 7 is fixedly connected with a connecting plate 16.

[0031] A positioning groove 17 is provided at the bottom of the right outer wall of the main body 1, and a pull plate groove 18 is provided on the front outer wall of the main body 1. The pull plate groove 18 is connected with the positioning groove 17 through a connecting groove 19. A spring 20 is fixedly connected to the inner wall of the pull plate groove 18, and there are multiple springs 20. A pull plate 21 is installed on the inner wall of the pull plate groove 18, and the other ends of the multiple springs 20 are fixedly connected to the inner wall of the pull plate 21. A handle 22 is fixedly connected to the outer wall of the pull plate 21, and a locking block 23 is fixedly connected to the inner wall of the pull plate 21. The locking block 23 passes through the connecting groove 19 and extends to the inside of the positioning groove 17. A positioning block 24 is fixedly connected to the left outer wall of the main body 1, and a locking groove 25 is provided on the outer wall of the positioning block 24.

[0032] When the heights of all lifting plates 7 are adjusted, the two main bodies 1 are spliced ​​together in pairs. When the left and right main bodies 1 are spliced ​​together, the positioning block 24 connected to the left outer wall of the right main body 1 is inserted into the positioning groove 17 opened on the right outer wall of the left main body 1. In this process, the positioning block 24 on the left side of the right main body 1 pushes the locking block 23 in the positioning groove 17 on the right side of the left main body 1 toward the outside of the left main body 1. At this time, the spring 20 inside the left main body 1 is in a compressed state. After the positioning block 24 connected to the right side of the right main body 1 completely enters the positioning groove 17 opened on the right side of the left main body 1, the multiple springs 20 in the left main body 1 rebound, so that the locking block 23 in the positioning groove 17 opened on the left main body 1 returns to its place, thereby locking and connecting the two main bodies 1.

[0033] The right outer wall of the main body 1 is provided with two slots 26 , and the left outer wall of the main body 1 is fixedly connected with two plugging plates 27 .

[0034] Working principle: Rotating the turntable 12 drives the driven bevel gear 9 to rotate. Since the driven bevel gear 9 is meshed with the driving bevel gear 10, the driven bevel gear 9 and the driving bevel gear 10 rotate synchronously, so that the two moving blocks 4 move back to back. When the two moving blocks 4 and the moving U-shaped plate 5 connected on the top move back to back together, the bottoms of the two linkage rods 6 move back to back with the two moving U-shaped plates 5. The other ends of the two linkage rods 6 push up the two lifting U-shaped plates 8 and the lifting plate 7, so that the lifting plate 7 is moved out from the top of the main body 1. The height of the lifting plate 7 can be adjusted according to different usage scenarios. When the height of all the lifting plates 7 is adjusted, the two main bodies 1 are connected. When the left and right main bodies 1 are spliced ​​in pairs, the positioning block 24 connected to the left outer wall of the right main body 1 is inserted into the positioning groove 17 opened on the right outer wall of the left main body 1. In this process, the positioning block 24 on the left side of the right main body 1 pushes the locking block 23 in the positioning groove 17 on the right side of the left main body 1 toward the outside of the left main body 1. At this time, the spring 20 inside the left main body 1 is in a compressed state. After the positioning block 24 connected to the right side of the right main body 1 completely enters the positioning groove 17 opened on the right side of the left main body 1, the multiple springs 20 in the left main body 1 rebound, so that the locking block 23 in the positioning groove 17 opened in the left main body 1 returns to its place, thereby locking and connecting the two main bodies 1.
