Description
Technical Field
[0001] This application relates to the field of highway protection facilities technology, and in particular to an installation support structure for guardrail panels. Background Technology
[0002] Highway guardrail systems are crucial traffic safety facilities. When a vehicle collides, the guardrail deforms to absorb the impact force between the vehicle and the guardrail, thus protecting the vehicle and its passengers. One type of guardrail installation support structure is composed of multiple rectangular plates welded together. When the guardrail needs to be installed, the support plates are fixed to the top of the posts with bolts, and then multiple guardrail plates are connected through the support plates to form a highway guardrail.
[0003] When using the aforementioned support plates to assemble guardrails, in the event of a vehicle collision, the support plates can only absorb the impact force through the deformation of the rectangular plates themselves. As a result, when the collision force between the vehicle and the guardrail is large, the energy absorption effect of the support plates is insufficient, thereby increasing the risk of passenger injury. Utility Model Content
[0004] In order to improve the energy absorption effect of highway guardrails, this application provides an installation support structure for guardrail panels.
[0005] This application provides a mounting support structure for guardrail panels, which adopts the following technical solution: A mounting support structure for a guardrail panel includes: Top plate, which is fixedly installed at the top of the column; Side plates, two of which are symmetrically arranged along the top plate, each of which is fixedly connected to the bottom end of the top plate, and each of which is fixedly provided with mounting holes; Mounting plates are provided one-to-one with the side plates. Each mounting plate is fixedly mounted on the corresponding side plate, and each mounting plate is fixedly provided with a connection hole. An energy-absorbing component is fixedly disposed between the two side plates and can absorb the impact force generated when a vehicle collides with the guardrail.
[0006] By adopting the above technical solution, when installing guardrails, the top plate is placed on top of the post, aligning the mounting holes of the side plates with the bolt holes on the post. After the side plates are adjusted, they are fixed to the post with bolts. After the side plates are connected to the post, the connecting holes on the guardrail and mounting plate are aligned, and the guardrail is fixed to the mounting plate with bolts. Once the guardrail and mounting plate are connected, the installation of the guardrail is complete. After installation, when a vehicle collides with the guardrail, the vehicle first contacts and impacts the guardrail, causing it to deform. The guardrail then deforms towards the side plates until it contacts the energy-absorbing component. Under the pressure of the guardrail, the energy-absorbing component rapidly collapses and deforms, absorbing the impact force between the vehicle and the guardrail, thus greatly reducing the impact force and significantly minimizing the risk of passenger injury.
[0007] Optionally, the energy-absorbing element includes: An energy-absorbing plate, wherein the energy-absorbing plate is fixedly disposed between the two side plates; An energy-absorbing tube is fixedly disposed at one end of the energy-absorbing plate; An energy-absorbing cover is fixedly disposed at the end of the energy-absorbing tube away from the energy-absorbing plate.
[0008] By adopting the above technical solution, when a vehicle collides with the guardrail, the guardrail deforms in the direction of the energy-absorbing cover upon impact, until the guardrail contacts and compresses the energy-absorbing cover. Under the compression of the guardrail, the energy-absorbing cover rapidly collapses and deforms. After deformation, the energy-absorbing cover initially absorbs the impact force between the vehicle and the guardrail. The deformation further compresses the energy-absorbing tube, which further collapses under the compression of the guardrail and the energy-absorbing cover. After collapse, the energy-absorbing tube further absorbs the impact force between the vehicle and the guardrail. Through the dual absorption of impact force by the energy-absorbing cover and the energy-absorbing tube, the impact force generated when the vehicle collides with the guardrail can be absorbed, thereby improving the energy absorption effect of the guardrail.
[0009] Optionally, the outer wall of the energy-absorbing tube is provided with multiple collapse holes at intervals.
[0010] By adopting the above technical solution, when a vehicle collides with the guardrail, the vehicle will first compress the guardrail, causing it to deform. After the guardrail deforms, it will compress the energy-absorbing cover. Under the compression of the guardrail, the energy-absorbing cover will quickly deform and absorb energy. After the energy-absorbing cover deforms, the guardrail will further compress the energy-absorbing tube. Under the compression of the guardrail and the energy-absorbing cover, the energy-absorbing tube will further deform and absorb energy. During the deformation of the energy-absorbing tube, the setting of the collapse hole can not only guide the energy-absorbing tube to collapse in a horizontal direction, but also ensure that the impact force transmitted to the energy-absorbing tube can be evenly distributed in various parts of the energy-absorbing tube, avoiding excessive impact force on the energy-absorbing tube in a local area, which would cause the energy-absorbing tube to break directly, thereby effectively improving the energy absorption efficiency of the energy-absorbing tube.
[0011] Optionally, the energy-absorbing shroud is vertically provided with a collapse guide groove, which is connected to the energy-absorbing tube.
[0012] By adopting the above technical solution, when a vehicle collides with the guardrail, the guardrail first contacts the vehicle and deforms under the impact. After deformation, the guardrail moves towards the energy-absorbing shield and compresses it. The energy-absorbing shield, under the compressive force from the guardrail, rapidly collapses and deforms, absorbing part of the impact force between the vehicle and the guardrail. During the collapse deformation of the energy-absorbing shield, the collapse guide groove ensures that the energy-absorbing shield collapses horizontally along the direction of the groove, preventing displacement during collapse. This avoids excessive local stress and breakage of the energy-absorbing shield due to displacement, effectively improving its stability during collapse and energy absorption.
[0013] Optionally, the outer wall of the energy-absorbing tube is provided with multiple reinforcing ribs at intervals.
[0014] By adopting the above technical solution, when the energy-absorbing tube is squeezed and collapses under the pressure of the energy-absorbing shroud, the setting of the reinforcing ribs can not only limit the outward expansion deformation of the energy-absorbing tube during the collapse process, but also guide the energy-absorbing tube to collapse layer by layer along the axial direction, thereby ensuring that the impact force can be evenly distributed and absorbed by the energy-absorbing tube, thus greatly improving the energy absorption effect of the energy-absorbing tube.
[0015] Optionally, two collapse guide posts are provided at intervals at the end of the energy-absorbing shroud away from the energy-absorbing tube.
[0016] By adopting the above technical solution, the crumple zone guide post not only ensures that when the guardrail is impacted and deforms, the guardrail first contacts and compresses the crumple zone guide post, which then deforms and absorbs part of the impact force, but also guides the guardrail towards the energy-absorbing shield after absorbing some of the impact force. The crumple zone guide post design prevents the energy-absorbing shield from experiencing excessive impact force upon vehicle collision, thus avoiding instantaneous rupture and effectively improving the stability of the energy-absorbing shield under impact.
[0017] Optionally, a first limiting plate is fixedly provided at the end of the top plate away from the mounting plate.
[0018] By adopting the above technical solution, when it is necessary to install the guardrail, the top plate is placed on the top of the post, and the first limiting plate is in contact with the post. After the first limiting plate contacts the post, it can not only prevent the top plate from shifting when the side plate is fixed to the post with bolts, but also ensure that the mounting holes of the side plate and the bolt holes on the post are aligned. This enables the top plate and post to be quickly positioned and fixed when installing the guardrail, thereby effectively improving the convenience of installing the guardrail.
[0019] Optionally, a second limiting plate is fixedly provided at the bottom end of both side plates.
[0020] By adopting the above technical solution, when it is necessary to install the guardrail, the top plate is placed on the top of the post, and the two second limiting plates are in contact with the post. After the second limiting plates are in contact with the post, the side plate is prevented from being displaced by external force when it is fixed to the post, thereby improving the stability of the side plate when installing the guardrail.
[0021] In summary, the present invention provides an installation support structure for guardrail panels, which includes at least one of the following beneficial technical effects: 1. When installing guardrails, place the top plate on top of the post, aligning the mounting holes of the side plates with the bolt holes on the post. After adjusting the side plate position, secure the side plate to the post with bolts. Then, align the guardrail with the connecting holes on the mounting plate and secure it with bolts. Once the guardrail is connected to the mounting plate, the installation is complete. After installation, when a vehicle collides with the guardrail, the vehicle first contacts and impacts the guardrail, causing it to deform. The guardrail then deforms towards the side plates until it contacts the energy-absorbing component. Under the pressure of the guardrail, the energy-absorbing component rapidly collapses and absorbs the impact force between the vehicle and the guardrail, greatly reducing the impact force and thus significantly minimizing the risk of passenger injury.
[0022] 2. When a vehicle collides with the guardrail, the guardrail deforms towards the energy-absorbing shroud upon impact, until the guardrail contacts and compresses the shroud. Under this compression, the shroud rapidly collapses, initially absorbing the impact force. The deformed shroud further compresses the energy-absorbing tube, which then collapses further under the pressure of the guardrail and shroud, further absorbing the impact force. Through the dual absorption of impact force by the energy-absorbing shroud and energy-absorbing tube, the impact force generated during a vehicle-guardrail collision is effectively absorbed, thus improving the guardrail's energy absorption efficiency.
[0023] 3. When a vehicle collides with a guardrail, the vehicle first compresses the guardrail, causing it to deform. After deformation, the guardrail compresses the energy-absorbing shroud. Under the pressure of the guardrail, the energy-absorbing shroud rapidly deforms and absorbs energy. After the energy-absorbing shroud deforms, the guardrail further compresses the energy-absorbing tube. Under the pressure of the guardrail and the energy-absorbing shroud, the energy-absorbing tube further deforms and absorbs energy. During the deformation of the energy-absorbing tube, the design of the crumple zone not only guides the energy-absorbing tube to crumple in a horizontal direction, but also ensures that the impact force transmitted to the energy-absorbing tube is evenly distributed throughout the tube. This prevents the energy-absorbing tube from being subjected to excessive impact force in a localized area, which could lead to its direct breakage. This effectively improves the energy absorption efficiency of the energy-absorbing tube. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0027] Combination Figure 1 This application discloses an installation support structure for a guardrail 16, including a top plate 1, side plates 11, mounting plates 13, and energy-absorbing components 2. The top plate 1 is fixedly installed at the top of the column 15. Two side plates 11 are symmetrically arranged along the top plate 1. Each side plate 11 is fixedly connected to the bottom end of the top plate 1, and each side plate 11 is fixedly provided with mounting holes 12. The mounting plates 13 are arranged one-to-one with the side plates 11. Each mounting plate 13 is fixedly installed on the corresponding side plate 11, and each mounting plate 13 is fixedly provided with connecting holes 14. The energy-absorbing components 2 are fixedly installed between the two side plates 11. The energy-absorbing components 2 can absorb the impact force generated when a vehicle collides with the guardrail 16.
[0028] In this embodiment, the top plate 1 has a rectangular structure, and the side plate 11 has a rectangular structure. They can be integrally formed and fixedly connected to the top plate 1, or they can be connected by welding; no specific limitation is made in this embodiment. The mounting plate 13 has a rectangular structure. The mounting plate 13 can be integrally formed and fixedly connected to the side plate 11, or it can be connected by welding; no specific limitation is made in this embodiment. The energy-absorbing component 2 is integrally formed and fixedly connected to the side plate 11.
[0029] In practical use, when the guardrail 16 needs to be installed, the top plate 1 is placed on top of the post 15, and the mounting holes 12 on the side plate 11 are aligned with the bolt holes on the post 15. The side plate 11 is then fixedly connected to the post 15 with bolts. After the side plate 11 and post 15 are connected, the guardrail 16 is aligned with the connection holes 14 on the mounting plate 13, and the guardrail 16 is fixedly connected to the mounting plate 13 with bolts. After the guardrail 16 is connected, when a vehicle collides with the guardrail 16 and causes the guardrail 16 to deform, the energy-absorbing component 2 can absorb the impact force between the vehicle and the guardrail 16, thereby reducing the damage of the guardrail 16 to the vehicle and ensuring the safety of passengers.
[0030] Combination Figure 2 and Figure 3 In a specific embodiment, the energy-absorbing component 2 includes an energy-absorbing plate 21, an energy-absorbing tube 22, and an energy-absorbing cover 23. The energy-absorbing plate 21 is fixedly disposed between two side plates 11, the energy-absorbing tube 22 is fixedly disposed at one end of the energy-absorbing plate 21, and the energy-absorbing cover 23 is fixedly disposed at the end of the energy-absorbing tube 22 away from the energy-absorbing plate 21. Multiple collapse holes 3 are spaced apart on the outer wall of the energy-absorbing tube 22. The energy-absorbing cover 23 has a vertically arranged collapse guide groove 4, which communicates with the energy-absorbing tube 22. Multiple reinforcing ribs 5 are spaced apart on the outer wall of the energy-absorbing tube 22. Two collapse guide posts 6 are spaced apart at the end of the energy-absorbing cover 23 away from the energy-absorbing tube 22.
[0031] In this embodiment, the energy-absorbing plate 21 is integrally formed and fixedly connected to the side plate 11. The energy-absorbing tube 22 can be integrally formed and fixedly connected to the energy-absorbing plate 21, or it can be connected by welding; no specific limitation is made in this embodiment. The energy-absorbing cover 23 is integrally formed and fixedly connected to the energy-absorbing tube 22. The collapse guide groove 4 is a rectangular groove, the collapse hole 3 is a rectangular hole, and the reinforcing rib 5 is a rectangular structure. The reinforcing rib 5 is integrally formed and fixedly connected to the energy-absorbing tube 22. The collapse guide post 6 is a cylindrical structure. The collapse guide post 6 can be integrally formed and fixedly connected to the energy-absorbing cover 23, or it can be connected by welding; no specific limitation is made in this embodiment.
[0032] In practical use, when a vehicle hits the guardrail 16, the guardrail 16 deforms under the impact and moves towards the collapsible guide post 6 until the guardrail 16 contacts and squeezes the collapsible guide post 6. After being squeezed by the guardrail 16, the collapsible guide post 6 absorbs part of the impact force and guides the guardrail 16 towards the energy-absorbing cover 23 until the guardrail 16 contacts and squeezes the energy-absorbing cover 23. After being squeezed, the energy-absorbing cover 23 collapses and deforms and further absorbs the impact force. After being squeezed, the energy-absorbing cover 23 moves towards the energy-absorbing tube 22 under the guidance of the collapsible guide groove 4 until the energy-absorbing cover 23 contacts the energy-absorbing tube 22. After being squeezed by the energy-absorbing cover 23, the energy-absorbing tube 22 collapses and deforms and absorbs the remaining impact force. During the collapse and deformation of the energy-absorbing tube 22, the reinforcing rib 5 provides additional support for the energy-absorbing tube 22, preventing it from being subjected to a large impact force during the collapse and deformation process, which could lead to the direct breakage of the energy-absorbing tube 22. The collapse hole 3 ensures that during the collapse and absorption of impact force, the impact force can be evenly distributed to various parts of the energy-absorbing tube 22, thereby preventing excessive local stress during the collapse process and the resulting local breakage of the energy-absorbing tube 22.
[0033] Combination Figure 1 and Figure 2 In a specific embodiment, a first limiting plate 7 is fixedly provided at the end of the top plate 1 away from the mounting plate 13. A second limiting plate 8 is fixedly provided at the bottom end of each of the two side plates 11.
[0034] In this embodiment, the first limiting plate 7 is an arc-shaped plate. The first limiting plate 7 can be fixedly connected to the top plate 1 by integral molding or by welding. No specific limitation is made in this embodiment. The second limiting plate 8 is a rectangular plate. The second limiting plate 8 is fixedly connected to the side plate 11 by integral molding.
[0035] In practical use, when the guardrail 16 needs to be installed, the top plate 1 is placed on the top of the post 15, and the first limiting plate 7 is in contact with the second limiting plate 8 and the post 15. After the first limiting plate 7, the second limiting plate 8 and the post 15 are in contact, when the side plate 11 is fixed to the post 15 by bolts, when the top plate 1 and the side plate 11 are subjected to external force and are about to slide, the first limiting plate 7, the second limiting plate 8 and the post 15 abut against each other, so that the top plate 1 and the side plate 11 will not be displaced, thereby improving the stability of the guardrail 16 during installation.
[0036] The principle of this embodiment is as follows: When the guardrail 16 needs to be installed, the top plate 1 is placed on the top of the column 15, and the mounting holes 12 on the side plate 11 are aligned with the bolt holes on the column 15. The side plate 11 and the column 15 are then fixedly connected by bolts. After the side plate 11 and the column 15 are connected, the guardrail 16 is aligned with the connection holes 14 on the mounting plate 13, and the guardrail 16 and the mounting plate 13 are fixedly connected by bolts. After the guardrail 16 is connected, when a vehicle collides with the guardrail 16 and causes the guardrail 16 to deform, the energy-absorbing component 2 can absorb the impact force between the vehicle and the guardrail 16, thereby reducing the damage of the guardrail 16 to the vehicle and ensuring the safety of passengers.
[0037] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
