Description

Technical Field

[0001] This invention relates to the field of guardrail technology, and in particular to a guardrail for municipal bridges and its usage method. Background Technology

[0002] Currently, guardrails are installed along the edges of municipal bridges, primarily to prevent vehicles from running off the bridge. Therefore, these guardrails have good impact resistance. Most of these guardrails are currently made of concrete or steel, which has high hardness. When a vehicle hits one, it not only suffers severe damage, but also, due to the fact that the front of the vehicle brakes for a very short time upon impact, the rear wheels of the vehicle are very likely to lift off the ground due to inertia. Once the height off the ground reaches a certain level, it will cause the vehicle to roll over.

[0003] A search revealed that this utility model, with publication number CN219410539U, discloses a liftable guardrail for municipal bridges, comprising a drive mechanism, a lifting mechanism, and a buffer mechanism. A servo motor drives a rotating rod, which in turn drives a first bevel gear to rotate a second bevel gear, which in turn drives a threaded rod. The rotation of the threaded rod causes a lifting rod to rise and fall within a fixed rod, which in turn causes a lifting plate to rise and fall. The rising and falling of the lifting plate causes a lifting frame to rotate under the action of a slider, slide rail, slide groove, limit shaft, and limit plate. This design provides both protection and auxiliary lifting functions, eliminating the need for manual lifting and lowering of the guardrail beside the bridge, thus increasing the safety of workers and saving time and effort.

[0004] The guardrail also has the following disadvantages during use: protection is achieved by adjusting the height of the guardrail, but its structure is relatively complex, making it inconvenient to clean the internal lifting frame. In addition, when a vehicle is hit by a large force, the guardrail will tilt, and the vehicle will fly out along the tilted guardrail, resulting in low safety performance. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the inconvenience of cleaning the internal lifting frame during cleaning, and the low safety performance caused by the tilting of the guardrail and the vehicle flying off the tilted guardrail when a vehicle impacts the guardrail with great force. Therefore, this invention proposes a guardrail for municipal bridges and its usage method.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A guardrail for municipal bridges includes multiple sets of sliding seats installed on the bridge. The inner wall of each sliding seat is provided with a support rod, and the top of at least three of the support rods is fixedly provided with the same railing to form a guardrail.

[0008] The upper end of the support rod is provided with a bent part, which faces inward towards the bridge and forms an inward protrusion, increasing the vehicle impact distance;

[0009] At least three adjacent support rods are fixedly connected to a first connecting rod for reinforcing the guardrail;

[0010] A buffer mechanism, installed on the first connecting rod, is used to buffer and clamp the vehicle to prevent it from flying off the bridge.

[0011] A cleaning mechanism is installed on the railings to clean them, saving a lot of manpower. The distance between two adjacent railings is less than the length of the cleaning mechanism.

[0012] In one possible design, the buffer mechanism includes multiple sets of support frames embedded in the bridge deck. The support frames are located between two adjacent support rods. The outer walls of the support frames and the first connecting rod are rotatably fitted with rotating rings. The outer walls of the rotating rings are fixedly fitted with telescopic rods. The upper and lower sets of telescopic rods are rotatably fitted with the same second connecting rod at their respective close ends. The support rods are slidably disposed within the sliding seat. The bottom of the support rods is fixedly fitted with a limiting plate. The outer walls of the support rods are fitted with a first tension spring. The two ends of the first tension springs are respectively fixedly connected to the sliding seat and the limiting plate at their respective close ends.

[0013] In one possible design, the telescopic rod includes a sliding rod, a sleeve rod, and a second tension spring. One end of the sleeve rod is rotatably connected to a second connecting rod. The sliding rod is slidably disposed inside the sleeve rod. The sleeve rod contains a second tension spring, and both ends of the second tension spring are fixedly connected to the sliding rod and the sleeve rod respectively on their respective adjacent sides. The sliding rod is fixedly connected to a corresponding rotating ring.

[0014] In one possible design, the cleaning mechanism includes a first sliding ring slidably fitted onto the outer wall of the railing. A nozzle is provided on one side of the first sliding ring. Two water troughs are provided on the top of the bridge deck, located on one side of the railing. A sliding plate is slidably provided on the top of the water troughs. A first connecting pipe is fixedly provided on the top of the sliding plate. A second connecting pipe is slidably provided inside the first connecting pipe. A fixing block is fixedly provided on one side of the first sliding ring. The second connecting pipe passes through and is fixedly connected to the fixing block. One end of the second connecting pipe is connected to the nozzle through a third connecting pipe. A water pump is fixedly provided on the top of the sliding plate. The outlet end of the water pump is connected to the first connecting pipe through a fourth connecting pipe. A fifth connecting pipe is fixedly provided on the inlet end of the water pump. The fifth connecting pipe passes through the sliding plate and extends into the water troughs.

[0015] In one possible design, a rack is fixedly mounted on one side of the water tank, a motor is fixedly mounted on the top of the sliding plate, and the output end of the motor passes through the bottom of the sliding plate and is fixedly fitted with a gear that meshes with the rack.

[0016] In one possible design, two inserts are fixedly provided at both ends of the first sliding ring, and a second sliding ring and a third sliding ring are sleeved on the outer wall of the railing. A slot corresponding to the insert is opened on one side of the second sliding ring and the third sliding ring. The insert and the slot are interference-fitted. The nozzle is fixedly connected to one side of the third sliding ring. An installation groove is opened in the second sliding ring, and a sponge pad for wiping the railing is provided in the installation groove.

[0017] In one possible design, the inner wall of the first sliding ring is embedded with a plurality of balls, the outer wall of the railing is fixedly provided with a limiting strip, and the inner wall of the first sliding ring is provided with a groove that matches the limiting strip.

[0018] A method for using guardrails on municipal bridges includes the following steps:

[0019] S1. When the guardrail is hit by a vehicle, it will cause the second connecting rod to move. The movement of the second connecting rod can cause the telescopic rod to rotate and move, and at the same time cause the support rod to move downward. The vehicle is clamped and buffered by the first connecting rod and the guardrail.

[0020] S2. When the vehicle moves away from the support rod, the support rod automatically resets, causing the telescopic rod to reset as well.

[0021] S3. When the railing needs to be cleaned, the motor is started to move the sliding plate, which in turn moves the first sliding ring. At the same time, the water pump is started to pump water from the water tank. The water is sprayed out from the nozzle to rinse the railing and the sponge pad is used to wipe the railing.

[0022] S4. When the sponge pad needs to be replaced, pull the second sliding ring out from one side of the first sliding ring to replace the sponge pad.

[0023] In this application, when the guardrail is hit by a vehicle, it will cause the second connecting rod to move. The movement of the second connecting rod can cause the telescopic rod to rotate, and stretch the second tension spring through the sliding rod and sleeve rod to buffer the vehicle. At the same time, it will cause the support rod to move downward and cause the second connecting tube to slide inside the first connecting tube. The vehicle is clamped by the first connecting rod and the guardrail to prevent the vehicle from flying out of the guardrail. When the vehicle moves away from the support rod, the support rod and the second tension spring will automatically reset and drive the telescopic rod to reset.

[0024] When the railing needs to be cleaned, the motor is started to move the sliding plate, which in turn moves the first sliding ring. At the same time, the water pump is started to pump water from the water tank. The water is sprayed out from the nozzle to rinse the railing, and at the same time, the sponge pad is used to wipe the railing.

[0025] When the sponge pad needs to be replaced, pull the second sliding ring out from one side of the first sliding ring to replace the sponge pad.

[0026] In this invention, the protective railing for municipal bridges, through a buffer mechanism, can achieve the effect of buffering and clamping vehicles, effectively preventing vehicles from flying off the bridge surface when crossing the railing.

[0027] In this invention, a guardrail for municipal bridges can automatically clean the railings through a cleaning mechanism, saving a lot of manpower and eliminating the need for cleaning trucks, thus reducing cleaning costs. Furthermore, the water tank can be used to cultivate aquatic organisms, which can increase the aesthetic appeal and absorb some dust.

[0028] In this invention, a protective railing for municipal bridges is designed in a multi-segment shape, which facilitates replacement and maintenance, and reduces the cost of disassembly and assembly during maintenance, as well as labor.

[0029] In this invention, the combined use of the second connecting rod and the support rod can buffer the vehicle and clamp it, effectively preventing the vehicle from flying off the bridge surface across the guardrail. Furthermore, the first sliding ring allows for cleaning of the guardrail, saving manpower, facilitating use, and reducing maintenance costs. Attached Figure Description
