Description

Technical Field

[0001] This utility model relates to the field of highway traffic facilities technology, specifically to a median strip opening guardrail docking device. Background Technology

[0002] In the field of road traffic, median strips are widely used on various types of roads as an important facility for separating lanes in different directions and ensuring driving safety. However, in some specific scenarios, such as when emergency vehicles such as fire trucks and ambulances need to pass quickly, or when there is road construction or temporary traffic control, median strips need to have openings to allow vehicles and pedestrians to pass flexibly.

[0003] Currently, the existing guardrail structures used at openings in median barriers mostly have certain limitations. Some opening guardrail structures are fixed, and opening and closing operations are cumbersome, making it impossible to quickly respond to passage needs in emergency situations. For example, when emergency rescue vehicles need to pass urgently, the difficulty in opening the guardrail may delay rescue time.

[0004] Some guardrails with openings in the median strip, while possessing a degree of mobility, suffer from poor stability. When vehicles frequently pass through these openings, the guardrails are prone to swaying, shifting, or even tipping over. This not only affects the guardrails' protective effect on vehicles but may also pose safety hazards to passing vehicles and pedestrians.

[0005] Furthermore, considering the connection structure of the guardrails, many traditional guardrails are not robust or reliable enough. The connection between adjacent guardrail panels often uses simple bolts or welding. Over long-term use, factors such as vehicle collisions and environmental erosion can easily cause the connection points to loosen or break, leading to a decrease in the overall structural strength of the guardrail and rendering it unable to effectively perform its isolation and protection functions.

[0006] Moreover, the existing guardrail openings in the median strip lack systematic consideration in their overall layout and design. The connections between different sections of the guardrail (such as standard sections, transition sections, fixed sections, and movable sections) are not tight enough, and the spacing, height, and other parameters of each section of the guardrail lack unified planning and coordination. This makes the entire guardrail opening in the median strip visually untidy and unattractive, and also affects the integrity and consistency of its function.

[0007] In view of the problems existing in the above-mentioned technologies, it is of great practical significance to develop a barrier with an opening that can be opened and closed conveniently and quickly, has good stability and reliable connection structure, and has a reasonable, beautiful and practical overall layout. Utility Model Content

[0008] To address the aforementioned issues, this utility model provides a median strip opening guardrail docking device. Through its unique design and structure, this median strip opening guardrail achieves the technical effects of rapid opening and closing, good stability, reliable connection structure, and a reasonable, aesthetically pleasing, and practical overall layout.

[0009] The technical solution of this utility model is as follows:

[0010] A median strip opening guardrail docking device is installed at the opening of two adjacent median strips. It includes a movable guardrail section, comprising posts C, brackets C, locking posts, and guardrail panels. Several posts C, made of square tubing, are evenly distributed at the opening. Each post C has a caster wheel at its bottom. Square locking holes corresponding to the posts C are evenly distributed on the road surface at the opening. Each post C is equipped with a locking post that mates with the locking hole. The locking post is a square tubing that fits with the inner hole of the post C. The locking post passes through the top of the post C and is inserted into the locking hole. Several guardrail panels are sequentially fixedly connected to the posts C to form a movable guardrail panel strip. Four parallel movable guardrail panel strips are installed on both sides of each post C.

[0011] The top of the locking post is equipped with a cover, which covers the top of post C.

[0012] Adjacent guardrail panels are fixedly connected by a guardrail panel connecting structure.

[0013] The guardrail connection structure includes steel plates and pins. A steel plate is fixedly installed on the inner side of the end of the guardrail.

[0018] A standard section of guardrail consists of two rows of several parallel posts A and guardrail panels. Posts A are pre-embedded and fixed in the road surface. Several guardrail panels are sequentially fixed and connected to posts A to form a standard section of guardrail panel. Four standard section guardrail panel strips are set on the outside of posts A, one above the other. The distance between two standard section guardrail panel strips in the same horizontal direction is greater than the distance between fixed section guardrail panel strips or movable end guardrail panel strips. The distance between two fixed section guardrail panel strips in the same horizontal direction is the same as the distance between movable end guardrail panel strips.

[0019] The transition section guardrail consists of two rows of several parallel posts A and guardrail panels. The posts A are pre-embedded and fixed in the road surface. Several guardrail panels are sequentially fixed and connected to the posts A to form the transition section guardrail panel strip. Four parallel transition section guardrail panel strips are set on the outside of the posts A. The spacing between two transition section guardrail panel strips in the same horizontal direction on the side closer to the standard section guardrail panel strip is the same as the spacing between the standard section guardrail panel strips. The spacing between two transition section guardrail panel strips in the same horizontal direction on the side closer to the fixed end guardrail panel strip is the same as the spacing between the fixed section guardrail panel strips.

[0036] like Figure 1 As shown, the guardrail for the opening of the isolation zone is set at the opening between two adjacent isolation zones. It mainly includes movable section guardrail 3, fixed section guardrail 2, standard section guardrail 5 and transition section guardrail 1. Through reasonable structural design and connection method, each part realizes the flexible opening and closing of the isolation zone opening, while ensuring the stability and safety of the guardrail.

[0037] like Figure 2 As shown, the movable section guardrail 3 consists of posts C31, locking posts 33, and guardrail panels 7.

[0038] The C31 post is made of square tubing and has casters 311 at the bottom for easy movement of the guardrail. Several C31 posts are evenly distributed on the road surface 6 at the opening to ensure the stable support of the guardrail.

[0039] The locking pin 33 is a square tube that fits with the inner hole of the column C31 with a clearance and is inserted from the top of the column C31.

[0040] Square locking holes 61 corresponding to the posts C31 are evenly distributed on the road surface 6. The locking posts 33 are inserted into the locking holes 61 to lock the guardrail.

[0041] The top of the locking post 33 is welded with a cover 331, which covers the top of the post C31. This serves two purposes: first, to prevent debris from entering, and second, to facilitate the removal of the locking post 33 from the post C31.

[0042] Several guardrail panels 7 are sequentially fixedly connected to the posts C31 to form movable guardrail panels. Brackets C32 are welded onto the posts C31, and the guardrail panels 7 are fixedly connected to the brackets C32 by bolts. On both sides of the posts C31, there are four movable guardrail panels running parallel to each other, with two movable guardrail panels on each side, enhancing the protective effect of the guardrail.

[0043] Adjacent guardrail panels 7 are fixedly connected by guardrail panel connecting structure 8, such as... Figures 5 to 7As shown, the guardrail connection structure 8 includes a steel plate 82 and pins 83. A steel plate 82 is fixedly installed on the inner side of the end of the guardrail 7. Corresponding positions of the steel plates 82 on adjacent guardrail 7 are staggered. Concentric pin holes 821 are provided on the steel plates 82, and pins 83 are inserted into the pin holes 821 to achieve a secure connection between the guardrail plates. Channel steel 81 is welded to both sides of the steel plate 82, and the channel steel 81 is fixed to the guardrail 7 with bolts to enhance the stability of the connection structure.

[0044] like Figure 3 As shown, the fixed section guardrail 2 consists of posts B21 and guardrail panels 7.

[0045] Two posts B21 are embedded in the road surface 6 as the supporting structure for the fixed section of the guardrail. Four guardrail panels 7 are fixed to the posts B21 by brackets B22, forming a fixed section of the guardrail panel that is consistent with the movable section of the guardrail panel.

[0046] The guardrail panels 7 on the fixed section guardrail strip are fixedly connected to the corresponding guardrail panels 7 on the movable section guardrail strip through the guardrail panel connection structure 8 to ensure the stability of the overall structure.

[0047] The standard section of guardrail 5 consists of two rows of several parallel posts A11 and guardrail panels 7.

[0048] Post A11 is pre-embedded and fixed in the road surface 6, and several guardrail panels 7 are sequentially fixed to post A11 through bracket A12 to form a standard section of guardrail panel strip.

[0049] Four standard guardrail sections are installed on the outside of post A11, running parallel to each other. The distance between two standard guardrail sections on the same horizontal direction is greater than the distance between fixed guardrail sections or movable guardrail sections.

[0050] like Figure 4 As shown, the structure of the transition section guardrail 1 is similar to that of the standard section guardrail 5, consisting of two rows of several parallel posts A11 and guardrail panels 7. The standard section guardrail panels on both sides of the standard section guardrail 5 are parallel, while the transition section guardrail 1, in order to connect the standard section guardrail 5 and the fixed end guardrail 2 of different widths, has its transition section guardrail panels at a certain angle. The posts A11 are pre-embedded and fixed in the road surface 6, and several guardrail panels 7 are sequentially fixed and connected to the posts A11 to form the transition section guardrail panels. Four parallel transition section guardrail panels are set on the outside of the posts A11. The spacing between two transition section guardrail panels on the same horizontal direction near the standard section guardrail panels is the same as the spacing between the standard section guardrail panels; the spacing between two transition section guardrail panels on the same horizontal direction near the fixed end guardrail panels is the same as the spacing between the fixed section guardrail panels, realizing a smooth transition of the guardrail.

[0051] This barrier with openings in the median strip, through its rational structural design and connection method, allows for flexible opening and closing of the openings while ensuring the stability and safety of the barrier. The omnidirectional wheels on the movable sections allow for easy movement, and the locking posts and holes enable quick locking. The robust and reliable connection structure of the guardrail panels can withstand long-term vehicle collisions and environmental erosion without easily loosening or breaking. The overall layout is reasonable, aesthetically pleasing, and practical, enhancing both the functionality and visual appeal of the barrier with openings in the median strip.
