Description

Technical Field

[0001] This utility model relates to the field of road guardrail auxiliary components, specifically to road crash barriers with buffering function. Background Technology

[0002] Road guardrails are traffic safety facilities installed on the outer side of road shoulders, traffic dividers, and pedestrian curbs. They absorb collision energy through deformation or vehicle elevation, thereby changing the vehicle's direction of travel, preventing the vehicle from going off the road or entering the oncoming lane, and minimizing injury to occupants.

[0003] In existing technologies, guardrails are usually installed in the middle of road crash barriers to achieve the effect of protection and isolation. Road crash barriers usually include guardrails and posts installed on both sides of the guardrails. However, in actual use, existing road crash barriers lack reinforced buffering components, so when they are subjected to accidental collisions, not only is their own buffering capacity ineffective, but they are also immediately deformed and damaged by the impact, resulting in mediocre performance. Utility Model Content

[0004] The purpose of this utility model is to provide a road crash barrier with a buffer function to solve the above problems, as detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The road crash barrier with buffer function provided by this utility model includes a barrier body and barrier posts. Multiple barrier bodies and barrier posts are provided, and the barrier bodies are fixedly installed between adjacent barrier posts to form an integral road crash barrier for crash protection and isolation on the road. The exterior of the guardrail body is covered with shock-absorbing and buffering components to enhance the buffering capacity of the guardrail body by covering the exterior of the guardrail body with the shock-absorbing and buffering components. Each shock-absorbing and buffering component is provided with a disassembly and assembly assembly on its exterior, and each shock-absorbing and buffering component is detachably and fixedly assembled to the exterior of the corresponding guardrail body through the disassembly and assembly assembly assembly.

[0006] Preferably, each guardrail post is fixedly equipped with a frustum-shaped guardrail base at its bottom.

[0007] Preferably, the shock-absorbing and buffering components all include a buffer liner and reinforcing ribs. The buffer liner is an inverted U-shaped bushing that is clipped onto the outside of the guardrail body from top to bottom and covers the outside of the guardrail body. The reinforcing ribs are evenly distributed and fixedly connected on the outer surface of the buffer liner.

[0008] Preferably, the buffer lining is an inverted U-shaped rubber strip or a high-density foam lining, and the bottom of the buffer lining is not lower than the bottom of the guardrail body.

[0009] Preferably, the reinforcing ribs are integrally formed with the buffer liner and are both vertically arranged outside the buffer liner. At the same time, the bottom end of the reinforcing ribs is higher than the bottom end of the buffer liner and is offset from the disassembly and assembly assembly.

[0010] Preferably, each of the disassembly and assembly components includes a fixing plate and a tensioning stud. The fixing plate is an inverted U-shaped plate that is vertically clamped to the outside of the buffer liner from top to bottom. The bottom of the fixing plate is lower than the buffer liner, and the lower part of the front and rear vertical sections of the fixing plate is vertically provided with a mating groove. At the same time, the mating grooves are all through grooves in the longitudinal direction and are aligned with each other. The tensioning stud is installed in the longitudinal direction between the mating grooves in the front and rear positions in a sliding fit. The part of the tensioning stud that extends out of the mating groove is coaxially engaged with a locking nut.

[0011] Preferably, the mating slots are all waist-shaped slots with open bottoms, and the top of the mating slots is higher than the bottom of the buffer liner.

[0012] Preferably, the fixing plates are all steel U-shaped plates, and the top inner circumference is in close contact with the top outer circumference of the buffer liner.

[0013] Preferably, a connecting plate is provided between the front and rear of the two tensioning studs of the same disassembly and assembly assembly. Both ends of the connecting plate are provided with mating holes along the longitudinal direction, and the mating holes at both ends of the connecting plate are fitted onto the outside of the tensioning stud by means of coaxial sliding engagement with the tensioning stud.

[0014] Preferably, the connecting cross plates are all rectangular strips, and the top of the connecting cross plates is lower than the bottom of the reinforcing ribs. The tensioning studs are all coaxially slidably fitted with anti-loosening washers on the portions corresponding to the connecting cross plates and the locking nuts.

[0015] In practical application, the aforementioned road crash barrier with buffer function utilizes a shock-absorbing and buffering assembly that wraps around the outside of the barrier body. This assembly features an inverted U-shaped buffer liner that covers the barrier body from top to bottom. This buffer liner enhances the barrier's cushioning capacity, providing stable and effective shock absorption during accidental collisions and protecting the barrier body from deformation. Furthermore, the fixing plates of the assembly are used to secure the barrier from top to bottom. The shock-absorbing and buffering assembly is externally mounted on the guardrail body by means of a tension stud and a locking nut inserted longitudinally through the mating groove. This method of assembling the shock-absorbing and buffering assembly externally to the guardrail body is simple and easy to implement, facilitating quick and secure assembly for enhanced cushioning. Furthermore, by simply unscrewing the locking nut and removing the tension stud, the fixing plate can be moved from bottom to top and removed from the top of the shock-absorbing and buffering assembly, thus releasing the limiting fixation on the assembly and allowing it to be disassembled. The shock-absorbing and buffering assembly is easily and readily detached from the main body of the guardrail, facilitating its quick removal for maintenance and replacement. Furthermore, the slot of the assembly is oblong with an open bottom. By first sliding the tensioning stud along the slot to contact the bottom of the shock-absorbing and buffering assembly before tightening the locking nut, the fixing plate can stably limit and fix the shock-absorbing and buffering assembly. Simultaneously, loosening the locking nut and disengaging the tensioning stud from the bottom of the slot also allows for quick removal of the assembly. Tightening the studs facilitates the quick upward movement of the fixing plate and its removal from the shock-absorbing and buffering assembly, thereby improving the assembly and disassembly efficiency of the assembly during use. Furthermore, since connecting plates are provided between adjacent tightening studs, and the mating holes at both ends of the connecting plates are fitted onto the outside of the tightening studs through a coaxial sliding fit, the connecting plates between adjacent fixing plates can be connected as a whole, further enhancing the secure fixation of the shock-absorbing and buffering assembly to the outside of the guardrail body.

[0016] The beneficial effects are as follows: 1. This utility model has a shock-absorbing and buffering component wrapped around the outside of the guardrail body. The buffering liner of the shock-absorbing and buffering component is an inverted U-shaped bushing. By covering the outside of the guardrail body from top to bottom with the buffering liner, the buffering capacity of the guardrail body can be improved. It can not only play a good and stable shock-absorbing and buffering effect when it suffers accidental collision, but also buffer and protect the guardrail body to reduce the degree of deformation. 2. By using the fixing plate of the assembly and disassembly to clamp onto the outside of the shock-absorbing and buffering component from top to bottom, and by adding tensioning studs and locking nuts through the longitudinal groove, the shock-absorbing and buffering component can be assembled and fixed to the outside of the guardrail body. The assembly method of the shock-absorbing and buffering component on the outside of the guardrail body is simple and easy to achieve, which facilitates the quick and secure assembly of the shock-absorbing and buffering component on the outside of the guardrail body for use to enhance the buffering effect. 3. Simply unscrew the locking nut and remove the tensioning stud in sequence to move the fixing plate from bottom to top and remove it from the top of the shock-absorbing and buffering assembly. This releases the limiting fixation of the shock-absorbing and buffering assembly and allows it to be removed from the outside of the guardrail body. The method of removing the shock-absorbing and buffering assembly from the outside of the guardrail body is simple and easy to achieve, which facilitates the quick removal of the shock-absorbing and buffering assembly from the outside of the guardrail body for maintenance and replacement. 4. The mating slot of the disassembly and assembly assembly is an oblong slot with an open bottom. By first sliding the tension stud along the mating slot to contact the bottom of the shock-absorbing and buffering assembly, and then tightening the lock nut, the fixing plate can stably limit and fix the shock-absorbing and buffering assembly. At the same time, by loosening the lock nut and disengaging the tension stud from the bottom of the mating slot, the tension stud can be quickly removed. This makes it easy to quickly move the fixing plate upward and remove it from the shock-absorbing and buffering assembly, which helps to improve the disassembly and assembly efficiency of the disassembly and assembly assembly during use. 5. A connecting horizontal plate is provided between adjacent tension studs, and the mating holes at both ends of the connecting horizontal plate are fitted onto the outside of the tension studs by means of coaxial sliding fit with the tension studs. In this way, by adding a connecting horizontal plate between adjacent fixing plates, the fixing plates connected on both sides can be connected as a whole, thereby further improving the reliability of the assembly and disassembly assembly in fixing the shock absorption and buffer components to the outside of the guardrail body.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] See Figures 1-7As shown, this utility model provides a road crash barrier with a buffer function, including a barrier body 5 and barrier posts 2. Multiple barrier bodies 5 and barrier posts 2 are provided, and barrier bodies 5 are fixedly installed between adjacent barrier posts 2 to form an integral road crash barrier for collision prevention and isolation protection on the road. Shock-absorbing buffer components 1 are wrapped around the exterior of each barrier body 5 to enhance the buffering capacity of the barrier body 5 by covering it with the shock-absorbing buffer components 1. The shock-absorbing and buffering components 1 all include a buffer liner 102 and reinforcing ribs 101. The buffer liner 102 is an inverted U-shaped bushing that is clipped onto the outside of the guardrail body 5 from top to bottom and covers the outside of the guardrail body 5. The outer surface of the buffer liner 102 is uniformly and fixedly equipped with reinforcing ribs 101. The purpose of this arrangement is to improve the buffering capacity of the guardrail body 5 by using the buffer liner 102 of the shock-absorbing and buffering components 1 to cover the outside of the guardrail body 5 from top to bottom.

[0022] See Figures 1-6 As shown, each shock-absorbing and buffering component 1 is externally equipped with a disassembly and assembly assembly 4, and each shock-absorbing and buffering component 1 is detachably and fixedly assembled to the outside of the corresponding guardrail body 5 through the disassembly and assembly assembly 4. Specifically, each disassembly and assembly assembly 4 includes a fixing plate 405 and a tensioning stud 403. The fixing plate 405 is an inverted U-shaped plate that is vertically clamped to the outside of the buffer outer liner 102 from top to bottom. The bottom end of the fixing plate 405 is lower than the buffer outer liner 102, and the lower part of the front and rear vertical parts of the fixing plate 405 is vertically provided with a mating groove 404. At the same time, the mating grooves 404 are all through grooves in the longitudinal direction and are aligned with each other. The mating grooves 404 at the front and rear positions are longitudinally inserted and fitted with tensioning studs 403 in a sliding fit manner, and the tensioning studs 403 extend outwards. The outer end of the matching slot 404 is coaxially engaged with a locking nut 402. The purpose of this arrangement is that, firstly, by disassembling and assembling the assembly 4, the fixing plate 405 is clamped from top to bottom onto the outside of the shock-absorbing buffer assembly 1. Then, by longitudinally passing through the matching slot 404 and installing the tension stud 403 and locking nut 402, the shock-absorbing buffer assembly 1 can be assembled and fixed to the outside of the guardrail body 5. At the same time, by simply unscrewing the locking nut 402 and removing the tension stud 403, the fixing plate 405 can be moved from bottom to top and removed from the top of the shock-absorbing buffer assembly 1. This releases the limiting fixation of the shock-absorbing buffer assembly 1 and allows the shock-absorbing buffer assembly 1 to be removed from the outside of the guardrail body 5. The assembly and disassembly of the shock-absorbing buffer assembly 1 on the outside of the guardrail body 5 is simple and easy to implement.

[0023] See Figures 1-7As shown, the following optimizations have been made to this application. Specifically, each guardrail post 2 is fixedly equipped with a frustum-shaped guardrail base 3 at its bottom end to improve the stability of the guardrail post 2 during installation. Optionally, the buffer liner 102 is an inverted U-shaped rubber strip or high-density foam bushing, and the bottom end of the buffer liner 102 is not lower than the bottom end of the guardrail body 5, so that the buffer liner 102 itself has a good and stable shock absorption effect. Furthermore, the reinforcing rib 101 is integrally formed with the buffer liner 102 and is vertically arranged on the outside of the buffer liner 102. The bottom end of the reinforcing rib 101 is higher than the bottom end of the buffer liner 102 and is offset from the disassembly assembly 4. This arrangement firstly facilitates the enhancement of the buffer bushing's resistance to deformation and overall strength through the reinforcing rib 101, and also prevents interference between the reinforcing rib 101 and the disassembly assembly 4.

[0024] See Figures 1-7 As shown, the mating slots 404 are all waist-shaped slots with open bottoms, and the top of the mating slots 404 is higher than the bottom of the buffer liner 102. With this configuration, by first sliding the tension stud 403 along the mating slots 404 to contact the bottom of the shock-absorbing buffer assembly 1, and then tightening the locking nut 402, the fixing plate 405 can stably limit and fix the shock-absorbing buffer assembly 1. At the same time, by loosening the locking nut 402 and disengaging the tension stud 403 from the bottom of the mating slots 404, the tension stud 403 can be quickly removed, which facilitates the quick upward movement of the fixing plate 405 and its removal from the shock-absorbing buffer assembly 1. Optionally, the fixing plates 405 are all steel U-shaped plates with their top inner circumference in close contact with the top outer circumference of the buffer liner 102. This makes the fixing plates 405 easy to process and manufacture, facilitating mass production, and also providing a clear indication when the fixing plates 405 are installed in place.

[0025] See Figures 1-7As shown, a connecting horizontal plate 406 is provided between the front and rear of the two tensioning studs 403 of the same disassembly and assembly assembly 4. Both ends of the connecting horizontal plate 406 are provided with mating holes 407 along the longitudinal direction. The mating holes 407 at both ends of the connecting horizontal plate 406 are fitted onto the outside of the tensioning stud 403 by means of coaxial sliding engagement with the tensioning stud 403. The reason for this arrangement is that by adding a connecting horizontal plate 406 between adjacent fixing plates 405, the fixing plates 405 connected on both sides can be connected into a whole, thereby further improving the reliability of the disassembly and assembly assembly 4 in fixing the shock-absorbing buffer assembly 1 to the outside of the guardrail body 5. Alternatively, the connecting horizontal plates 406 are all rectangular strips, and the top of the connecting horizontal plate 406 is lower than the bottom of the reinforcing rib 101. The tensioning stud 403 is coaxially slidably fitted with anti-loosening washers 401 in the part between the corresponding connecting horizontal plate 406 and the locking nut 402. With this setting, firstly, it is easy for the connecting horizontal plate 406 to not interfere with the reinforcing rib 101. Secondly, it is easy to improve the anti-loosening effect of the locking nut 402 after tightening by pressing the anti-loosening washer 401.

[0026] With the above structure, in practical use, since a shock-absorbing buffer assembly 1 is wrapped around the outside of the guardrail body 5, and the buffer liner 102 of the shock-absorbing buffer assembly 1 is an inverted U-shaped bushing, the buffer liner 102 of the shock-absorbing buffer assembly 1 covers the outside of the guardrail body 5 from top to bottom. This enhances the buffering capacity of the guardrail body 5, providing a good and stable shock-absorbing effect in the event of an accidental collision, and also protecting the guardrail body 5 to reduce deformation. Furthermore, the fixing plate 405 of the disassembly and assembly assembly 4 is fastened to the outside of the shock-absorbing buffer assembly 1 from top to bottom and extends along... By longitudinally inserting the tensioning stud 403 and locking nut 402 into the slot 404, the shock-absorbing buffer assembly 1 can be assembled and fixed to the outside of the guardrail body 5. This assembly method is simple and easy to implement, facilitating a quick and secure installation of the shock-absorbing buffer assembly 1 to enhance its cushioning effect. Furthermore, by simply unscrewing the locking nut 402 and removing the tensioning stud 403, the fixing plate 405 can be moved from bottom to top and removed from the top of the shock-absorbing buffer assembly 1. This releases the limiting fixation of the shock-absorbing buffer assembly 1, allowing it to be detached from the outside of the guardrail body 5, thus improving the shock absorption effect. The disassembly of shock-absorbing component 1 outside the guardrail body 5 is simple and easy to implement, which facilitates the quick removal of shock-absorbing component 1 from the guardrail body 5 for maintenance and replacement. Furthermore, since the mating groove 404 of the disassembly and assembly component 4 is an oblong groove with an open bottom, the method of first sliding the tension stud 403 along the mating groove 404 to contact the bottom of the shock-absorbing component 1 and then tightening the locking nut 402 allows the fixing plate 405 to stably limit and fix the shock-absorbing component 1. Simultaneously, by loosening the locking nut 402 and allowing the tension stud 403 to disengage from the bottom of the mating groove 404, the tension stud 403 can be quickly removed, thus facilitating... Moving the fixing plate 405 quickly upward and removing it from the shock-absorbing and buffering assembly 1 helps improve the efficiency of disassembly and assembly of the disassembly and assembly assembly 4 during use. Since there are connecting horizontal plates 406 between adjacent tension studs 403, and the mating holes 407 at both ends of the connecting horizontal plates 406 are all fitted onto the outside of the tension studs 403 by sliding coaxially with them, the connecting horizontal plates 406 between adjacent fixing plates 405 can be connected into a whole, thereby further improving the reliability of the disassembly and assembly assembly 4 in fixing the shock-absorbing and buffering assembly 1 to the outside of the guardrail body 5.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
