Description

Technical Field

[0001] The utility model relates to the technical field of municipal guardrails, in particular to a municipal guardrail with an anti-collision component. Background Art

[0002] Guardrails are mainly used to protect personal safety and equipment facilities in residential areas, roads, commercial areas, public places and other places. Guardrails can be seen everywhere in our lives.

[0003] Publication No. CN219671177U discloses a municipal guardrail with an anti-collision structure. By arranging an anti-collision hanger and an impact buffer bag, after the impact buffer bag at the front end of the anti-collision hanger is impacted, the impact buffer bag is sunken and deformed, and the wet sand pile inside the sealing belt layer flows under pressure along the connecting pipe to the inside of the anti-collision hanger. The wet sand pile inside the anti-collision hanger is ejected from the impact-fragmented sealed outer walls that are compressed and ruptured on both sides of the anti-collision hanger. The ejected wet sand pile effectively absorbs and transfers the kinetic energy impact caused by the car collision, thereby effectively alleviating the impact force and protecting the structural integrity of the guardrail column. This solves the problem that the existing municipal guardrail is easily broken and damaged when impacted, resulting in a decrease in the protective performance of the road guardrail and its deformation easily affecting traffic safety. However, this patent still has the following problems in actual use:

[0004] Although this municipal guardrail with an anti-collision structure utilizes the soaked sand pile inside the anti-collision hanger to be sprayed out from the impact-fragmented sealed outer walls on both sides of the anti-collision hanger that are compressed and ruptured, and the sprayed soaked sand pile effectively absorbs and transfers the kinetic energy impact caused by the car collision, the device sets the anti-collision hangers at both ends of the guardrail, resulting in protection of only the two ends of the guardrail, and the middle position cannot be well buffered and anti-collision, thereby reducing the practicality of the guardrail.

[0005] A municipal guardrail with an anti-collision component is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the present utility model is to provide a municipal guardrail with an anti-collision component to solve the problem proposed in the above-mentioned background technology that the wet sand pile inside the anti-collision hanger is sprayed out from the impact-fragmented sealed outer wall that is compressed and ruptured on both sides of the anti-collision hanger, and the sprayed wet sand pile effectively absorbs and transfers the kinetic energy impact caused by the collision of the car. However, the device sets the anti-collision hangers at both ends of the guardrail, resulting in protection of only the two ends of the guardrail, and the middle position cannot be well buffered and anti-collision, thereby reducing the practicality of the guardrail.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a municipal guardrail with an anti-collision assembly, comprising an anti-collision mechanism and an anti-collision guardrail installed on the outside of the anti-collision mechanism;

[0008] Both ends of the top of the anti-collision mechanism are provided with a limiting mechanism, and one end of the limiting mechanism is engaged and connected to the inside of the anti-collision guardrail;

[0009] Also includes:

[0010] The anti-collision mechanism includes a support column, and the left and right sides of the support column are both connected with anti-collision guardrails;

[0011] Among them, the interior of the anti-collision guardrail is fixedly connected with a plurality of support shafts, the number of the support shafts is four, and the support shafts are evenly distributed inside the anti-collision guardrail;

[0012] Among them, several rubber rollers are rotatably connected to the outer side of the support shaft. The number of the rubber rollers is five, and the rubber rollers are evenly distributed on the outer side of the support shaft. The anti-collision guardrail is fixedly connected to support plates on both sides close to the left and right sides of the support shaft.

[0013] Preferably, grooves are symmetrically provided inside the left and right sides of the support plate, guide rods are fixedly connected inside the two grooves, and first springs are sleeved on the outer sides of the two guide rods.

[0014] Preferably, both ends of the first spring are fitted with a sliding sleeve, the inner wall of the sliding sleeve is slidably connected to the guide rod, the end of the sliding sleeve away from the first spring is fitted with a particle damper, one end of the particle damper passes through the guide rod and is fixedly connected to the support plate.

[0015] Preferably, one side of the sleeve is rotatably connected to a connecting rod, and the end of the connecting rod away from the sleeve is rotatably connected to a buffer plate. The upper and lower ends of one side of the buffer plate are fixedly connected to cylinders, and one end of the two cylinders is provided with a sleeve.

[0016] Preferably, one end of the sleeve is fixedly connected to the support plate, one end inside the sleeve is fixedly connected to a second spring, one end of the second spring is fit-connected to the cylinder, and the other end inside the sleeve is fixedly connected to damping particles.

[0017] Preferably, the limiting mechanism includes a fixed block, one side of the fixed block is fixedly connected to the support column, a limiting groove is provided inside the fixed block, and a connecting rod is provided inside the limiting groove.

[0018] Preferably, one end of the connecting rod passes through the fixed block and is fixedly connected to a ball handle, a third spring is sleeved on the outer side of the connecting rod, and one end of the connecting rod close to the third spring is fixedly connected to a barrier rod, one end of the barrier rod is fitly connected to the anti-collision guardrail, and the other end of the barrier rod is fixedly connected to a limiting plate.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: the municipal guardrail with an anti-collision assembly can absorb or transfer most of the impact force by providing an anti-collision mechanism, thereby increasing the service life of the anti-collision guardrail, and can limit the anti-collision guardrail by providing a limiting mechanism to prevent the anti-collision guardrail from falling out of the support column. The specific contents are as follows:

[0020] 1. By setting up an anti-collision mechanism, most of the impact force can be absorbed or transferred, thereby improving the service life of the anti-collision guardrail. When the anti-collision guardrail is hit, the cooperation between the rubber roller and the support shaft can transfer most of the impact force. When the buffer plate is compressed, the second spring is compressed to reduce a part of the impact force. Then the second spring resets the cylinder. The cylinder resets and contacts the damping particles to absorb the rebound force, thereby playing a buffering role. The buffer plate drives the two sliding sleeves to squeeze the first spring at the same time. The compression of the first spring absorbs a part of the impact force. Then the first spring resets and drives the sliding sleeve to contact the particle damping to absorb the rebound force, thereby effectively reducing the damage of the impact force to the anti-collision guardrail.

[0021] 2. By setting a limiting mechanism, the anti-collision guardrail can be limited to prevent the anti-collision guardrail from falling out of the support column. The thrust of the third spring can ensure that the barrier rod is always engaged with the anti-collision guardrail without external force, so as to limit the anti-collision guardrail. By pulling out the ball handle to drive the barrier rod to move and rotating the ball handle, the position of the barrier rod can be fixed, and the barrier rod can be separated from the anti-collision guardrail, which is convenient for replacing the anti-collision guardrail.

[0033] The outer side of the support shaft 103 is rotatably connected to a plurality of rubber rollers 104. The number of rubber rollers 104 is five and the rubber rollers 104 are evenly distributed on the outer side of the support shaft 103. The left and right sides of the anti-collision guardrail 102 close to the support shaft 103 are fixedly connected to support plates 105. The upper and lower ends of the support plates 105 are fixedly connected to the anti-collision guardrail 102.

[0034] The support plate 105 has symmetrical grooves 106 on the left and right sides. The two grooves 106 are fixedly connected to the inside of the two guide rods 107. The outer sides of the two guide rods 107 are sleeved with first springs 108. By providing the two grooves 106, the anti-collision buffer effect can be achieved on both sides of the anti-collision guardrail 102.

[0035] Both ends of the first spring 108 are fitted with a sliding sleeve 109, the inner wall of the sliding sleeve 109 is slidably connected to the guide rod 107, and the end of the sliding sleeve 109 away from the first spring 108 is fitted with a particle damper 110. One end of the particle damper 110 passes through the guide rod 107 and is fixedly connected to the support plate 105. The first spring 108 is compressed to absorb part of the impact force, and then the first spring 108 is reset to drive the sliding sleeve 109 to contact the particle damper 110 to absorb the rebound force.

[0036] A connecting rod 111 is rotatably connected to one side of the sliding sleeve 109. The end of the connecting rod 111 away from the sliding sleeve 109 is rotatably connected to a buffer plate 112. The upper and lower ends of one side of the buffer plate 112 are fixedly connected to cylinders 113. One end of the two cylinders 113 is sleeved with a sleeve 114. By providing the connecting rod 111, the sliding sleeve 109 can be driven to move left and right outside the guide rod 107.

[0037] One end of the sleeve 114 is fixedly connected to the support plate 105. One end of the sleeve 114 is fixedly connected to a second spring 115. One end of the second spring 115 is in contact with the cylinder 113. The other end of the sleeve 114 is fixedly connected to damping particles 116. After the second spring 115 is compressed, a portion of the impact force is reduced. Then, the second spring 115 resets the cylinder 113. The cylinder 113 resets and contacts the damping particles 116, absorbing the rebound force, thereby providing a buffering effect.

[0038] The limiting mechanism 2 includes a fixed block 201, one side of the fixed block 201 is fixedly connected to the support column 101, a limiting groove 202 is provided inside the fixed block 201, a connecting rod 203 is provided inside the limiting groove 202, one end of the connecting rod 203 passes through the fixed block 201 and is fixedly connected to a ball handle 204, a third spring 205 is sleeved on the outer side of the connecting rod 203, and the end of the connecting rod 203 close to the third spring 205 is fixedly connected to a blocking rod 206, one end of the blocking rod 206 is fitly connected to the anti-collision guardrail 102, and the other end of the blocking rod 206 is fixedly connected to the limiting plate 207. The thrust of the third spring 205 can ensure that the blocking rod 206 is always engaged with the anti-collision guardrail 102 without being subjected to external force, thereby limiting the anti-collision guardrail 102.

[0039] Working principle: Before using this municipal guardrail with anti-collision components, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 8As shown, first pull out the ball handle 204 to drive the barrier rod 206 to move and rotate the ball handle 204 to fix the position of the barrier rod 206, so that the barrier rod 206 is retracted into the support column 101, and then the anti-collision guardrail is inserted into the support column 101. The ball handle 204 is rotated to utilize the reset force of the third spring 205 to drive the barrier rod 206 to be inserted into the anti-collision guardrail 102, and the anti-collision guardrail 102 can be fixed in the support column 101;

[0040] Secondly, when the anti-collision guardrail 102 is hit, most of the impact force can be transferred by utilizing the cooperation between the rubber roller 104 and the support shaft 103. When the buffer plate 112 is compressed, the second spring 115 is compressed to reduce a part of the impact force. Then the second spring 115 resets the cylinder 113. The cylinder 113 resets and contacts the damping particles 116 to absorb the rebound force, thereby playing a buffering role. The buffer plate 112 drives the two sliding sleeves 109 to squeeze the first spring 108 at the same time. The first spring 108 is compressed to absorb a part of the impact force. Then the first spring 108 is reset and drives the sliding sleeve 109 to contact the particle damping 110 to absorb the rebound force, thereby effectively reducing the damage of the impact force to the anti-collision guardrail 102.
