Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, and in particular to a noise reduction guardrail for municipal roads. Background Art

[0002] Municipal road guardrails are protective devices used to separate roads. They are also widely used to separate commercial areas, field isolation zones, shopping malls, municipal factory isolation zones, parks, and other areas. Municipal road guardrails primarily consist of guard posts and guardrails. Guard posts are also called uprights, vertical poles, support posts, or guardrail posts. Guard posts primarily support and fix the guardrails, while the guardrails primarily serve as barriers. To reduce noise, existing municipal road guardrails already have noise reduction features, specifically by improving the guardrail structure to achieve this noise reduction function.

[0003] Patent specification CN217758486U discloses a municipal road noise reduction guardrail. The guardrail utilizes a multi-hole sound-absorbing panel that concentrates and absorbs noise. The panel then eliminates the noise through partitions, the sound-absorbing material within the partitions, and springs. This prevents noise from passing through the guardrail, significantly reducing its reflection of sound waves and thus reducing noise. The guardrail has a three-layer, dual-cavity structure with springs within each cavity, providing a certain degree of collision protection.

[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: during the use of the above device, when the municipal road guardrail is frequently used, its frequent exposure to the sun and rain will reduce the service life of the guardrail, and will also affect the protective components inside the guardrail, thereby affecting the normal noise reduction effect. If the guardrail is replaced as a whole, the cost will increase. Therefore, further improvement is needed. Utility Model Content

[0005] The utility model provides a municipal road noise reduction guardrail, which solves the problem in the related art that it is inconvenient to quickly dismantle the sound insulation and protection components for replacement and maintenance.

[0006] The technical solution of the utility model is as follows:

[0007] A municipal road noise reduction guardrail, comprising a U-shaped bracket, a top cover is provided at the upper end of the U-shaped bracket, a U-shaped placement groove is provided on the inner wall of the U-shaped bracket, a baffle is fixedly connected to the inner wall of the U-shaped bracket, a through groove is provided on one side of the U-shaped bracket, the through groove passes through the inner wall of the U-shaped placement groove, a threaded groove is provided at the upper end of the U-shaped bracket, a threaded rod for fixedly connecting the top cover to the U-shaped bracket is provided on the upper end of the top cover, a guardrail assembly is provided inside the U-shaped bracket, and a threaded bolt for fixedly connecting the U-shaped bracket to the guardrail assembly is provided on one side of the U-shaped bracket.

[0008] Preferably, a top groove is opened at one end of the top cover, and the top groove corresponds to the U-shaped placement groove. A notch is opened through one end of the top cover, and the notch is connected and corresponds to the threaded groove. The threaded rod passes through the notch and is connected to the threaded groove by a thread.

[0009] Preferably, the guardrail assembly includes an outer plate arranged inside the U-shaped placement groove, a first porous sound-absorbing panel is provided on one side of the outer plate, a ring block is provided on one side of the first porous sound-absorbing panel, a second porous sound-absorbing panel is provided on one side of the ring block, and an inner plate is provided on one side of the second porous sound-absorbing panel.

[0010] Preferably, the outer plate, the first porous sound-absorbing plate, the ring block, the second porous sound-absorbing plate and the inner plate are all arranged inside the U-shaped placement groove.

[0011] Preferably, one side of the outer plate, the first porous sound-absorbing plate, the ring block, the second porous sound-absorbing plate and the inner plate is penetrated by a circular groove.

[0012] Preferably, the circular groove is connected to the through groove, the threaded bolt passes through the through groove and the interior of the circular groove in sequence and is connected to the threaded cap through threads, and the structures of the outer plate and the inner plate are symmetrical.

[0013] Preferably, functional grooves are evenly opened on one side of the outer plate, a blocking plate is provided on one side of the outer plate, a spring is fixedly connected to one side of the blocking plate, and one end of the spring is fixedly connected to the inner wall of the functional groove.

[0014] Preferably, a card slot is provided on the other side of the blocking plate, the card slot corresponds to the blocking plate, and reflective sheets are evenly provided on the other side of the blocking plate.

[0015] The working principle and beneficial effects of the utility model are as follows:

[0016] 1. The utility model separates the threaded rod from the threaded groove by rotating the threaded rod. At this time, the top cover can be removed from the top of the U-shaped bracket. Then the staff rotates the threaded bolt to separate it from the threaded cap. Then the staff removes the threaded bolt from the through groove and the inside of each group of circular grooves in turn. At this time, the staff can easily remove the outer plate, the first porous sound-absorbing panel, the ring block, the second porous sound-absorbing panel and the inner plate from the inside of the U-shaped placement groove, so that the removed sound insulation and protective components can be easily replaced and maintained, which solves the problem of inconvenience in quickly dismantling the sound insulation and protective components for their replacement and maintenance.

[0017] 2. The present invention can absorb as much noise generated by vehicles on the road as possible through the presence of the first porous sound-absorbing panel and the second porous sound-absorbing panel. The hollow design of the ring block allows for the existence of gaps within the entire device, thereby enhancing the noise reduction strength.

[0018] 3. The utility model can prevent the blocking plate from escaping from the range inside the U-shaped bracket by the presence of the baffle plate. The presence of the reflective sheet allows the driver to quickly observe the noise reduction guardrail, so that the driver can avoid the noise reduction guardrail as soon as possible. When the vehicle accidentally collides with the noise reduction guardrail, its blocking plate is hit first. At this time, the blocking plate will squeeze the spring. At this time, the spring will generate an opposite force to offset the impact force on the blocking plate, thereby reducing the impact on the noise reduction guardrail.

A through groove 13 is provided on one side of the U-shaped bracket 1, and the through groove 13 passes through the inner wall of the U-shaped placement groove 11. A threaded groove 14 is provided on the upper end of the U-shaped bracket 1. The U-shaped placement groove 11 is used to place the guardrail assembly 5, and the baffle 12 is used to prevent the components in the guardrail assembly 5 from leaving the range of the U-shaped bracket 1.

[0030] like Figure 3 As shown, a top groove 21 is provided at one end of the top cover 2, and the top groove 21 corresponds to the U-shaped placement groove 11. A notch 22 is provided at one end of the top cover 2, and the notch 22 is connected to and corresponds to the threaded groove 14. The threaded rod 3 passes through the notch 22 and is connected to the threaded groove 14 by threads. The threaded rod 3 is used to fix the top cover 2 and the U-shaped bracket 1 to prevent the upper end of the guardrail assembly 5 from being directly exposed to the outside world, thereby enhancing the service life of the guardrail assembly 5.

[0031] like Figure 4As shown, the guardrail assembly 5 includes an outer plate 51 arranged inside the U-shaped placement groove 11, a first porous sound-absorbing panel 52 is arranged on one side of the outer plate 51, a ring block 53 is arranged on one side of the first porous sound-absorbing panel 52, a second porous sound-absorbing panel 54 is arranged on one side of the ring block 53, an inner plate 55 is arranged on one side of the second porous sound-absorbing panel 54, and the outer plate 51, the first porous sound-absorbing panel 52, the ring block 53, the second porous sound-absorbing panel 54 and the inner plate 55 are all arranged Inside the U-shaped placement groove 11, a blocking plate 513 is provided on one side of the outer plate 51, and a card slot 5132 is opened on the other side of the blocking plate 513, and the card slot 5132 corresponds to the baffle 12. The other side of the blocking plate 513 is also evenly provided with a reflective sheet 5131. The first porous sound-absorbing panel 52 and the second porous sound-absorbing panel 54 are both used to absorb more vehicle noise. The reflective sheet 5131 is used to remind drivers passing by to prevent vehicles from hitting the guardrail.

[0032] like Figure 5 As shown, a circular groove 511 is formed through one side of the outer plate 51, the first porous sound-absorbing plate 52, the ring block 53, the second porous sound-absorbing plate 54, and the inner plate 55.

At this time, it is convenient for the staff to take out the outer plate 51, the first porous sound-absorbing plate 52, the ring block 53, the second porous sound-absorbing plate 54 and the inner plate 55 from the inside of the U-shaped placement groove 11 respectively, so that the removed sound insulation and protection components can be conveniently replaced and maintained. The first porous sound-absorbing plate 5 2 and the second porous sound-absorbing panel 54 can absorb as much noise as possible generated by vehicles on the road. The hollow design of the ring block 53 allows a gap to exist in the entire interior of the device, thereby enhancing the noise reduction strength. The presence of the baffle 12 can prevent the blocking plate 513 from leaving the range inside the U-shaped bracket 1. The presence of the reflective sheet 5131 allows the driver to quickly observe the noise reduction guardrail, allowing the driver to avoid the noise reduction guardrail as soon as possible. When a vehicle accidentally collides with the noise reduction guardrail, its blocking plate 513 is hit first. At this time, the blocking plate 513 will squeeze the spring 5133. At this time, the spring 5133 will generate an opposite force to offset the impact force on the blocking plate 513, thereby reducing the impact on the noise reduction guardrail.
