Description

Technical Field

[0001] The present invention belongs to the technical field of guardrails, and particularly relates to a corrugated guardrail with a buffering effect. Background Art

[0002] Highway guardrail plates use the deformation of the soil foundation, columns, and crossbeams to absorb collision energy, force out-of-control vehicles to change direction, restore to the normal driving direction, prevent vehicles from running off the road, protect vehicles and passengers, and reduce losses caused by accidents. When the road guardrail is impacted, it needs to have a certain buffering effect to avoid accidents caused by vehicles running off the road.

[0003] Existing road anti-collision guardrails basically absorb collision energy through the deformation of the soil foundation, columns, and crossbeams. However, this does not have a buffering effect. When a car hits the guardrail, there is no buffering force, and the guardrail is easily broken after being impacted, losing the protective function of the device. Therefore, this application proposes a corrugated guardrail with a buffering effect. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a corrugated guardrail with a buffering effect. The device adopts the settings of the first corrugated plate and the second corrugated plate to strengthen the guardrail, prevent breakage after impact, and ensure that the first corrugated plate and the second corrugated plate always have a protective function. The settings of the first buffer member and the second buffer member can both buffer the vehicle after impact.

[0005] In order to achieve the above purpose, the technical solution adopted by the present invention is:

The guide block is slidably installed on the guide rod. The first spring is sleeved on the guide rod. First clamps for fixing the fixing plate on the installation column are installed on both the upper and lower sides of the fixing plate;

[0008] Strip-shaped holes are formed in both the first corrugated plate and the second corrugated plate. The second buffer is arranged in the middle of the support frame, and the second buffer passes through the strip-shaped holes in the first corrugated plate and the second corrugated plate and is connected to the second corrugated plate. An installation part for facilitating the installation of the support frame on the installation column is also arranged in the middle of the support frame.

[0009] Preferably, through holes are formed on both sides of the center line on one side of the fixed plate. Guide rods are also fixedly installed on the support frame. The guide rods are symmetrically arranged on both sides of the center line of the support frame, and the guide rods are slidably connected to the through holes. Baffles are fixedly installed at the ends of the guide rods. The first hoop is provided to fix the device on the installation column.

The two support cross bars and the support vertical bars are arranged in parallel, and the two support vertical bars are symmetrically arranged at both ends of the support cross bar. The parallel support cross bars and the support vertical bars symmetrically arranged at both ends of the support cross bar are connected end to end to form a frame structure. Side ears are arranged on the support cross bars, and the side ears are fixed on the first corrugated plate by bolts and nuts. The support frame is used to support the normal operation of the first corrugated plate and the second corrugated plate. The support cross bars and the support vertical bars can both strengthen the first corrugated plate and the second corrugated plate, and ensure that the first corrugated plate and the second corrugated plate remain intact after being impacted.

[0011] Preferably, a fixed rod is arranged at the other end of the rotating arm. A waist-shaped hole is arranged on the support cross bar. The fixed rod is slidably arranged in the waist-shaped hole. An adjustment hole is fixedly formed in the middle of the support cross bar. The adjustment hole is matched with the installation part. The fixed rod and the waist-shaped hole can ensure the normal rotation of the rotating arm and the normal movement of the movable end of the rotating arm after impacting the first corrugated plate or the second corrugated plate.

[0012] Preferably, the installation part includes an installation rod, support rods arranged at both ends of the installation rod, support blocks arranged at both ends of the support rods, and a fixed frame. A fixed groove is formed in the middle of the support block. The fixed groove is slidably matched with the support cross bar. Sliding rods are arranged at the four corners of the fixed frame.

[0014] Preferably, a limiting block is arranged in the fixed groove. The limiting block is arranged in the adjusting hole and is slidably matched with the adjusting hole. A counterbore is also formed on the fixed frame. The counterbore is concentric with the through hole and is matched with the adjusting nut. The arrangement of the limiting block can prevent the support block from falling off the support cross bar during the movement of the support block along the support cross bar. At the same time, combined with the function of the adjusting hole, it can also provide a guiding purpose for the movement of the support block.

[0015] Preferably, the second buffer member includes a rotating shaft, a mounting seat, a first rotating rod, a second rotating rod, a moving rod and a reset mechanism. The rotating shafts are symmetrically arranged on both sides of the mounting member. The rotating shafts are rotatably installed on the support cross bar through the mounting seats. The first rotating rods are fixedly installed at both ends of the rotating shaft. Both ends of the moving rod are respectively rotatably connected to the first rotating rods at the ends of the rotating shafts on both sides of the mounting member. The reset mechanism is installed on one side of the support cross bar and is symmetrically arranged on both sides of the center line of the support cross bar. The reset mechanism is matched with the moving rod. One end of the second rotating rod is fixedly installed in the middle of the rotating shaft. The other end of the second rotating rod passes through the strip holes on the first corrugated plate and the second corrugated plate and extends to one side of the second corrugated plate. A fixing column is arranged at the other end of the second rotating rod. The fixing column is rotatably connected to the second rotating rod. The fixing column is fixedly installed on the second corrugated plate. The second buffer member can play a buffering role after the vehicle is impacted. When the second corrugated plate is knocked off by the vehicle, the second corrugated plate will move towards the first corrugated plate after receiving the impact force. During the movement of the second corrugated plate towards the first corrugated plate, one end of the second rotating rod rotates around the mounting seat. When the second rotating rod rotates, it will drive the rotating shaft to rotate. When the rotating shaft rotates, it will drive the first rotating rod to rotate. When the first rotating rod rotates, it will drive the moving rod to move towards the side close to the support cross bar. When the moving rod approaches the support cross bar, it will cooperate with the reset mechanism to achieve the purpose of buffering.

[0017] Preferably, a sliding block is also provided in the strip hole on the first corrugated plate, the second rotating rod is slidably connected to the sliding block, grooves are provided on the upper and lower sides of the sliding block, the grooves are slidably matched with the two side walls of the strip hole, and the setting of the sliding block can reduce the friction between the second rotating rod and the side wall of the strip hole, thereby increasing the service life of the second rotating rod and ensuring the normal operation of the device.

[0018] Preferably, the reset mechanism also includes a rotating roller, and limit plates are fixedly installed on both sides of the upper and lower sides of the center line of the lifting plate. The two ends of the rotating roller are respectively rotatably installed on the limit plates on the upper and lower sides of the center line of the lifting plate, and the rotating roller cooperates with the moving rod. The setting of the rotating roller can reduce the friction between the moving rod and the lifting plate during operation, reduce the degree of wear of the moving rod, and increase the service life of the moving rod. The setting of the limit plate can limit the moving rod and prevent the moving rod from leaving the range of the lifting plate during operation, thereby ensuring the normal operation of the moving rod and the normal buffering effect of the second buffer component.

[0019] The beneficial effects of the present invention are:

[0020] 1) The device adopts the setting of the first corrugated plate and the second corrugated plate to strengthen the guardrail, prevent breakage after impact, and ensure that the first corrugated plate and the second corrugated plate always have a protective effect. The setting of the first buffer and the second buffer can both serve the purpose of buffering after the vehicle impact. The first buffer and the second buffer can buffer the impacting vehicle twice, and can also serve the purpose of protecting the guardrail.

[0021] 2) The support frame of the device is used to support the normal operation of the first corrugated plate and the second corrugated plate. The support cross bar and the support vertical bar can strengthen the first corrugated plate and the second corrugated plate to ensure that the first corrugated plate and the second corrugated plate remain intact after being impacted.

[0022] 3) The setting of the fixed rod and the waist-shaped hole of the device can ensure the normal rotation of the rotating arm and the normal movement of the movable end of the rotating arm after hitting the first corrugated plate or the second corrugated plate.

[0023] 4) The setting of the installation parts of this device can fix the middle parts of the first corrugated plate and the second corrugated plate on the installation column, which is convenient for positioning when installing the two ends of the first corrugated plate and the second corrugated plate during the installation of this device, improving the installation efficiency and quality of this device.

[0024] 5) The setting of the adjusting nut and the threaded rod of this device can be used to adjust the distance between the fixed frame and the support frame. The function of the second spring can reset the fixed frame and also play a buffering role after the vehicle is impacted.

[0025] 6) The setting of the limit block of this device can prevent the support block from falling off the support crossbar during the process of moving along the support crossbar. At the same time, in cooperation with the adjusting hole, it can also provide a guiding function for the movement of the support block.

[0026] 7) The second buffer of this device can play a buffering role after the vehicle is impacted. When the vehicle impacts the second corrugated plate, the second corrugated plate will move toward the first corrugated plate side after receiving the impact force. During the process of the second corrugated plate moving toward the first corrugated plate, one end of the second rotating rod rotates around the mounting seat. When the second rotating rod rotates, it will drive the rotating shaft to rotate. When the rotating shaft rotates, it will drive the first rotating rod to rotate. When the first rotating rod rotates, it will drive the moving rod to move toward the support crossbar side. When the moving rod approaches the support crossbar, it will cooperate with the reset mechanism to achieve the buffering purpose.

[0027] 8) When the moving rod of this device moves toward the support crossbar side, it will press the lifting plate toward the support plate. The lifting plate approaching the support plate will drive the sliding column to move toward the lifting plate side, and the lifting plate will compress the third spring during the movement, thus playing a buffering role for the vehicle after the impact.

[0028] 9) The setting of the sliding block of this device can reduce the friction between the second rotating rod and the side wall of the strip hole, improve the service life of the second rotating rod, and ensure the normal operation of this device.

[0029] 10) The setting of the rotating roller of this device can reduce the friction during the operation of the moving rod and the lifting plate, reduce the wear degree of the moving rod, increase the service life of the moving rod. The setting of the limit plate can play a role in limiting the moving rod, preventing the moving rod from moving out of the range of the lifting plate during the operation, ensuring the normal operation of the moving rod and also ensuring the normal buffering function of the second buffer.

[0050] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0052] like Figure 1 , Figure 2 , Figure 11 As shown, a corrugated guardrail with a buffering effect includes a first corrugated plate 1, a second corrugated plate 2, a first buffer 6 and a second buffer 4. A support frame 3 is installed on the first corrugated plate 1, and the first buffer 6 is symmetrically arranged at both ends of the first support frame 3; the support frame 3 is used to support the device to ensure that the device is always in a stable state during operation.

[0053] like Figure 6 , Figure 7As shown, the first buffer 6 includes a fixed plate 601, a rotating arm 607, a fixed shaft 608, a push-pull rod 6011, a guide rod 605, a first spring 603, and a guide block 6010. An avoidance hole 606 is formed in the middle of the fixed plate 601. The two ends of the guide rod 605 are respectively fixedly installed in the avoidance hole 606. The setting of the avoidance hole 606 can ensure the normal installation and normal operation of the guide rod 605, and the setting of the avoidance hole 606 can also play a role in protecting the guide rod 605, improving the service life of the guide rod 605. The guide block 6010 is slidably installed on the guide rod 605. The first spring 603 is sleeved on the guide rod 605. The rotating arms 607 are symmetrically arranged on both sides of the center line of the fixed plate 601. The setting of the first spring 603 can drive the guide block 6010 to reset. At the same time, the first spring 603 can also play a buffering role during the movement of the guide block 6010. One end of the rotating arm 607 is rotatably installed on the fixed plate 601, and the other end of the rotating arm 607 is slidably connected to the support frame 3. The two ends of the fixed shaft 608 are respectively connected to the rotating arms 607 on both sides of the center line of the fixed plate 601. The push-pull rods 6011 are symmetrically arranged on both sides of the center line of the fixed shaft 608. The two ends of the push-pull rod 6011 are respectively rotatably installed on the guide block 6010 and the fixed shaft 608. First hoop 602 for facilitating the fixing of the fixed plate 601 on the mounting post 7 is installed on both the upper and lower sides of the fixed plate 601. The setting of the first hoop 602 facilitates the fixing of the device on the mounting post 7.

[0054] When the first corrugated plate 1 is impacted by a vehicle, the first corrugated plate 1 will move towards the side close to the mounting post 7. During the movement of the first corrugated plate 1, it will drive the support frame 3 to move towards the side close to the support frame 3 together. During the movement of the support frame 3, it will drive one end of the rotating arm 607 to move towards the side close to the mounting post 7. The rotating arm 607 will rotate around the hinge joint between the rotating arm 607 and the fixed plate 601. The other end of the rotating arm 607 will move along the support crossbar 301. While the rotating arm 607 rotates, it will cause the push-pull rod 6011 to push the guide block 6010 to move along the guide rod 605. While the guide block 6010 moves along the guide rod 605, it will compress the first spring 603, thereby achieving the purpose of buffering.

[0055] As Figure 1 , Figure 8As shown in the figure, strip-shaped holes 201 are formed in both the first corrugated plate 1 and the second corrugated plate 2. The second buffer member 4 is disposed in the middle of the support frame 3, and the second buffer member 4 passes through the strip-shaped holes 201 in the first corrugated plate 1 and the second corrugated plate 2 and is connected to the second corrugated plate 2. An installation member 5 for facilitating the installation of the support frame 3 on the installation column 7 is further disposed in the middle of the support frame 3. The installation member 5 is used to fixedly install the middle parts of the first corrugated plate 1 and the second corrugated plate 2 on the installation column 7, improving the installation efficiency and installation quality of the first corrugated plate 1 and the second corrugated plate 2.

[0056] In this embodiment, as Figure 6 shown, through holes 604 are formed on both sides of the center line on one side of the fixing plate 601. A guide rod 6012 is fixedly installed on the support frame 3. The guide rods 6012 are symmetrically disposed on both sides of the center line of the support frame 3, and the guide rods 6012 are slidably connected to the through holes 604. The arrangement of the guide rods 6012 can not only provide guidance for the movement of the first corrugated plate 1 or the second corrugated plate 2 after being impacted, but also strengthen the device.

[0057] In this embodiment, as Figure 3 shown, a baffle 6013 is fixedly installed at the end of the guide rod 6012. The arrangement of the baffle 6013 can prevent the large movement range of the guide rod 6012 from affecting the normal operation of the first buffer member 6.

[0058] In this embodiment, as Figure 3 shown, the support frame 3 includes support cross bars 301 and support vertical bars 303. There are two support cross bars 301 and support vertical bars 303. The two support cross bars 301 and support vertical bars 303 are arranged in parallel, and the two support vertical bars 303 are symmetrically disposed at both ends of the support cross bar 301. The parallel support cross bars 301 and the support vertical bars 303 symmetrically disposed at both ends of the support cross bar 301 are connected end to end to form a frame structure. Side ears 302 are arranged on the support cross bars 301, and the side ears 302 are fixed on the first corrugated plate 1 by bolts and nuts. The support frame 3 is used to support the normal operation of the first corrugated plate 1 and the second corrugated plate 2. The support cross bars 301 and the support vertical bars 303 can both strengthen the first corrugated plate 1 and the second corrugated plate 2, ensuring that the first corrugated plate 1 and the second corrugated plate 2 remain intact after being impacted.

[0059] In this embodiment, as Figure 7As shown in the figure, a fixing rod 609 is provided at the other end of the rotating arm 607, and a waist-shaped hole 305 is provided on the supporting cross bar 301. The fixing rod 609 is slidably arranged in the waist-shaped hole 305. An adjusting hole 304 is fixedly opened in the middle of the supporting cross bar 301. The adjusting hole 304 cooperates with the mounting member 5. The setting of the fixing rod 609 and the waist-shaped hole 305 can ensure the normal rotation of the rotating arm 607 and ensure the normal movement of the movable end of the rotating arm 607 after hitting the first corrugated plate 1 or the second corrugated plate 2.

[0060] In this embodiment, as Figure 4 , Figure 5 shown, the mounting member 5 includes a mounting rod 5011, support rods 504 arranged at both ends of the mounting rod 5011, support blocks 507 arranged at both ends of the support rods 504, and a fixing frame 502. A fixing groove 508 is opened in the middle of the support block 507. The fixing groove 508 is slidably matched with the supporting cross bar 301. Sliding rods 5010 are arranged at the four corners of the fixing frame 502. The sliding rods 5010 are slidably connected to the fixing frame 502. Second clamps 501 are arranged on both sides of the center line of the fixing frame 502. The setting of the mounting member 5 can fix the middle parts of the first corrugated plate 1 and the second corrugated plate 2 on the mounting column 7, which is convenient for positioning when installing the two ends of the first corrugated plate 1 and the second corrugated plate 2 during the installation of the device, and improves the installation efficiency and quality of the device.

[0061] In this embodiment, as Figure 4 , Figure 5 shown, the mounting member 5 further includes an adjusting nut 505 and a second spring 506. A threaded rod 503 is also fixedly installed on the support rod 504. Through holes (not shown in the figure) are opened on both sides of the fixing frame 502. One end of the threaded rod 503 passes through the through hole and extends to the other side of the through hole. The adjusting nut 505 is threadedly connected to the threaded rod 503. The second spring 506 is sleeved on the threaded rod 503, and the second spring 506 is located between the fixing frame 502 and the support rod 504. The setting of the adjusting nut 505 and the threaded rod 503 can achieve the purpose of adjusting the distance between the fixing frame 502 and the support frame 3. The function of the second spring 506 can reset the fixing frame 502, and can also play a buffering role after the vehicle is hit.

[0062] In this embodiment, as Figure 4As shown, a limiting block 509 is provided in the fixing groove 508. The limiting block 509 is arranged in the adjusting hole 304, and the limiting block 509 is in sliding fit with the adjusting hole 304. A countersunk head groove (not shown in the figure) is also formed in the fixing frame 502. The countersunk head groove is concentric with the through hole and is matched with the adjusting nut 505. The setting of the limiting block 509 can prevent the support block 507 from falling off the support cross bar 301 during the movement of the support block 507 along the support cross bar 301. At the same time, in cooperation with the function of the adjusting hole 304, it can also provide guidance for the movement of the support block 507.

[0063] In this embodiment, the setting of the adjusting hole 304, the support block 507 and the limiting block 509, when the fixing frame 502 is fixedly installed on the installation column 7 through the second hoop 501 and then the two ends of the first corrugated plate 1 are installed, pulling the first corrugated plate 1 will cause the limiting block 509 to move in the strip-shaped hole 201, and the fixing groove 508 on the support block 507 will move along the support rod 504, so as to achieve the purpose of adjusting the first corrugated plate 1 and ensure the installation efficiency and installation quality of the device.

[0064] In this embodiment, as Figure 3 , Figure 8 shown, the second buffer member 4 includes a rotating shaft 406, a mounting seat 4015, a first rotating rod 404, a second rotating rod 401, a moving rod 405 and a reset mechanism 402. The rotating shafts 406 are symmetrically arranged on both sides of the mounting member 5. The rotating shafts 406 are rotatably mounted on the support cross bar 301 through the mounting seats 4015. The first rotating rods 404 are fixedly installed at both ends of the rotating shafts 406. Both ends of the moving rod 405 are respectively rotatably connected to the first rotating rods 404 at the ends of the rotating shafts 406 on both sides of the mounting member 5. The reset mechanism 402 is installed on one side of the support cross bar 301 and is symmetrically arranged on both sides of the center line of the support cross bar 301. The reset mechanism 402 is matched with the moving rod 405. One end of the second rotating rod 401 is fixedly installed in the middle of the rotating shaft 406. The other end of the second rotating rod 401 passes through the strip-shaped holes 201 on the first corrugated plate 1 and the second corrugated plate 2 and extends to one side of the second corrugated plate 2. A fixing column 408 is arranged at the other end of the second rotating rod 401. The fixing column 408 is rotatably connected to the second rotating rod 401. The fixing column 408 is fixedly installed on the second corrugated plate 2. On the one hand, the fixing column 408 can serve the purpose of connecting the second rotating rod 401 and the second corrugated plate 2, and on the other hand, it can also serve the purpose of strengthening the second corrugated plate 2 and increasing the strength of the second corrugated plate 2.

[0065] The second buffer 4 can play a buffering role after a vehicle impact. When the vehicle impacts and knocks off the second corrugated plate 2, the second corrugated plate 2 will receive the impact force and move towards the side close to the first corrugated plate 1. During the process of the second corrugated plate 2 moving towards the first corrugated plate 1, one end of the second rotating rod 401 rotates around the mounting seat 4015. While the second rotating rod 401 rotates, it drives the rotating shaft 406 to rotate. When the rotating shaft 406 rotates, it drives the first rotating rod 404 to rotate. When the first rotating rod 404 rotates, it drives the moving rod 405 to move towards the side close to the support cross bar 301. When the moving rod 405 approaches the support cross bar 301, it cooperates with the reset mechanism 402 to achieve the purpose of buffering. When the second corrugated plate 2 coincides with the first corrugated plate 1 and continues to push the first corrugated plate 1, the first buffer 6 starts to work.

[0066] In this embodiment, as Figure 10 shown, the reset mechanism 402 includes a support plate 4013, a sliding column 4014, a third spring 4012, and a lifting plate 409. The support plate 4013 is fixedly installed on the side wall of the support cross bar 301. The sliding columns 4014 are fixedly installed on both sides of the center line of the lifting plate 409, and the sliding columns 4014 are slidably connected to the support plate 4013. The third spring 4012 is sleeved on the sliding columns 4014, and the third spring 4012 is located between the lifting plate 409 and the support plate 4013. The lifting plate 409 is slidably matched with the moving rod 405. When the moving rod 405 moves towards the side close to the support cross bar 301, it presses the lifting plate 409 towards the support plate 4013. When the lifting plate 409 approaches the support plate 4013, it drives the sliding columns 4014 to move towards the side close to the lifting plate 409, and the lifting plate 409 compresses the third spring 4012 during the moving process, thereby achieving the purpose of buffering the vehicle after impact.

[0067] In this embodiment, as Figure 8 、 Figure 9 shown, a sliding block 403 is further arranged in the strip hole 201 on the first corrugated plate 1. The second rotating rod 401 is slidably connected to the sliding block 403. Grooves 407 are formed on both the upper and lower sides of the sliding block 403, and the grooves 407 are slidably matched with the two side walls of the strip hole 201. The arrangement of the sliding block 403 can reduce the friction between the second rotating rod 401 and the side wall of the strip hole 201, improve the service life of the second rotating rod 401, and ensure the normal operation of the device.

[0068] In this embodiment, as Figure 10As shown, limiting plates 4010 are fixedly installed on both the upper and lower sides of the center line of the lifting plate 409. The setting of the limiting plates 4010 can limit the moving rod 405, prevent the moving rod 405 from deviating from the range of the lifting plate 409 during operation, ensure the normal operation of the moving rod 405, and also ensure the normal buffering function of the second buffer member 4.

[0069] In this embodiment, as Figure 10 shown, the reset mechanism 402 further includes a rotating roller 4011. The two ends of the rotating roller 4011 are respectively rotatably installed on the limiting plates 4010 on the upper and lower sides of the center line of the lifting plate 409, and the rotating roller 4011 cooperates with the moving rod 405. The setting of the rotating roller 4011 can reduce the friction between the moving rod 405 and the lifting plate 409 during operation, reduce the wear degree of the moving rod 405, and increase the service life of the moving rod 405.
