Description

Technical Field

[0001] This utility model relates to the field of guardrail technology, specifically to a liftable traffic construction anti-collision isolation guardrail. Background Technology

[0002] Traffic construction crash barriers are safety protection devices specifically designed for construction sites. They aim to effectively separate construction areas from normal traffic flow, preventing vehicles from accidentally entering the construction zone and ensuring the safety of construction workers and maintaining traffic order. Traditional traffic construction crash barriers are mostly fixed designs, unable to be height-adjusted according to actual site needs. This fixed design makes it difficult to adapt to changes in different construction stages and terrain conditions, leading to poor protective effects in some situations and potentially increasing the risk of accidents. Therefore, flexible and adjustable barriers are particularly important to quickly adapt to dynamic changes at the construction site.

[0003] Patent CN217812787U discloses a retractable guardrail for temporary roads, including a support frame. The support frame has an adjustment mechanism inside, extending to the outside of the support frame. The adjustment mechanism includes a motor fixedly connected to the bottom of the support frame. A roller is fixedly connected to the motor's output shaft. The top of the roller extends into the support frame and is fixedly connected to a gear. Racks mesh with the front and rear sides of the gear, and the outer ends of both racks extend to both sides of the support frame. The beneficial effect of this retractable guardrail for temporary roads is that by activating two cylinders, the overall height of the device can be adjusted relative to the surrounding environment, avoiding the need to modify the device's dimensions according to site conditions, thus preventing waste of labor and materials and significantly increasing construction costs.

[0004] The aforementioned existing technology allows for relative adjustment of the overall height of the device by activating two cylinders. However, this technology has some drawbacks: the cylinders are located at the bottom of the support frame, causing the support frame and all components above it to rise together when the cylinder's movable rod extends. This design increases the gap between the bottom of the guardrail and the ground, potentially affecting the guardrail's protective effect. Therefore, to address this deficiency, we propose a lifting traffic construction crash barrier, aiming to overcome the shortcomings of the existing technology and improve the overall protective effect. Utility Model Content

[0005] The purpose of this utility model is to provide a liftable traffic construction anti-collision isolation guardrail to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The retractable traffic construction crash barrier consists of two symmetrically arranged hollow columns, which serve as the main support frame, connecting and fixing the guardrail. Figure 1 , Figure 3 and Figure 7 As shown, a fixed railing is provided between the two hollow columns. The fixed railing serves as the basic structure, providing sliding guidance and support for the movable railing. The fixed railing includes a strip-shaped base plate, which is used to fix the T-shaped vertical bars and connect the hollow columns. The top of the strip-shaped base plate is provided with multiple T-shaped vertical bars arranged equidistantly from left to right. The T-shaped vertical bars are used to slide with the T-shaped connecting groove of the movable railing to achieve height adjustment. The fixed railing is movably connected to the movable railing, and the movable railing can adjust its height by raising and lowering to adapt to different construction protection needs.

[0008] The movable railing includes a strip-shaped top plate, which connects to strip-shaped vertical plates to form the frame structure of the movable part. The bottom of the top plate has multiple strip-shaped vertical plates arranged equidistantly from left to right. These vertical plates engage with T-shaped vertical rods via T-shaped connecting grooves to ensure vertical movement stability. A T-shaped connecting groove is vertically formed on the rear side of the bottom of each vertical plate, and the T-shaped vertical rod is slidably connected within it. The T-shaped connecting groove restricts the sliding trajectory of the movable railing, preventing deviation or derailment. A clamping bolt is threaded onto the front side of each vertical plate, near the bottom. The threaded end of the clamping bolt abuts against the front side of the T-shaped vertical rod, thus fixing the lifting position of the movable railing by pressing against the front side of the T-shaped vertical rod.

[0009] Preferred, such as Figure 3 As shown, the hollow column has a base at its bottom, which increases the contact area and improves the overall anti-tipping ability of the guardrail. Reflective stickers are attached to both the front and rear sides of the hollow column, which enhance the warning effect at night or in low visibility environments.

[0010] The hollow column is provided with U-shaped connecting blocks on both sides and near the bottom. The strip base plate is provided with docking blocks at both ends. The docking blocks are located in the corresponding U-shaped connecting blocks. The U-shaped connecting blocks are used to fix the docking blocks, so as to realize the quick assembly and disassembly of the fixed railing and the hollow column.

[0011] The front side of the U-shaped connecting block is provided with a mounting hole, and a fixing bolt is connected to the mounting hole. The threaded end of the fixing bolt is threaded to the front side of the mating block, and the fixing bolt fixes the mating block inside the U-shaped connecting block through the threaded connection.

[0012] The rear sides of the multiple T-shaped vertical bars are connected to multiple first strip horizontal plates arranged at equal intervals, which are used to enhance the lateral stability of the fixed railing.

[0013] The hollow column has multiple U-shaped support blocks arranged at equal intervals on both the left and right sides. The end of the first strip-shaped horizontal plate is located in the corresponding U-shaped support block. The U-shaped support block is used to support the end of the first strip-shaped horizontal plate and improve the overall structural strength.

[0014] Preferred, such as Figure 6 As shown, the front sides of the multiple strip vertical plates are connected to multiple second strip horizontal plates arranged at equal intervals. The second strip horizontal plates are used to connect the strip vertical plates, thereby enhancing the impact resistance and rigidity of the movable railing.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This lifting traffic construction crash barrier adopts a sliding fit structure of T-shaped vertical bars and T-shaped connecting grooves. The height of the movable barrier is adjusted by vertical movement. During the adjustment process, the gap between the bottom of the barrier and the ground does not change, avoiding the problem of bottom protection failure caused by the lifting device in the existing technology, and significantly improving the protection effect.

[0017] 2. This lifting traffic construction crash barrier can be fixed in position by manually tightening bolts, without relying on cylinders or motors, which simplifies the adjustment process, reduces the cost of use, and improves the reliability and adaptability of the device, making it suitable for complex construction environments.

[0018] 3. This lifting traffic construction crash barrier uses the first and second horizontal plates to form a reinforced structure, enhancing the impact resistance and overall rigidity of both fixed and movable railings. In the event of a vehicle collision, it can effectively disperse the impact force and improve safety protection performance.

[0019] 4. This lifting traffic construction crash barrier features a modular design with U-shaped connecting blocks and mating blocks, allowing for quick assembly and disassembly of the railings and hollow columns using fixing bolts, facilitating transportation and on-site assembly. The inclusion of reflective stickers further enhances nighttime warning functionality, reducing the risk of traffic accidents in construction areas caused by poor visibility.

[0030] Please see Figures 1-7 This utility model provides a technical solution:

[0031] The retractable traffic construction crash barrier includes two symmetrically arranged hollow columns 100, which serve as the main support frame and connect to the fixed railing 200. Figure 1 , Figure 3 and Figure 7As shown, a fixed railing 200 is provided between two hollow columns 100. The fixed railing 200 serves as the basic structure, providing sliding guidance and support for the movable railing 300. The fixed railing 200 includes a strip base plate 210, which is used to fix the T-shaped vertical bars 220 and connect the hollow columns 100. The top of the strip base plate 210 is provided with multiple T-shaped vertical bars 220 arranged equidistantly from left to right. The T-shaped vertical bars 220 are used to slide with the T-shaped connecting groove 321 of the movable railing 300 to achieve height adjustment. The movable railing 300 is movably connected to the fixed railing 200. The movable railing 300 can be adjusted in height by raising and lowering to adapt to different construction protection needs.

[0032] The movable railing 300 includes a strip-shaped top plate 310, which is used to connect strip-shaped vertical plates 320 to form the frame structure of the movable part. The bottom of the strip-shaped top plate 310 is provided with multiple strip-shaped vertical plates 320 arranged equidistantly from left to right. The strip-shaped vertical plates 320 cooperate with the T-shaped vertical rods 220 through T-shaped connecting grooves 321 to ensure vertical movement stability. The T-shaped connecting grooves 321 are vertically opened upward on the rear side of the bottom of the strip-shaped vertical plates 320. The T-shaped vertical rods 220 are slidably connected in the T-shaped connecting grooves 321. The T-shaped connecting grooves 321 are used to limit the sliding trajectory of the movable railing 300 to prevent deviation or derailment. A clamping bolt 340 is threadedly connected to the front side and near the bottom of the strip-shaped vertical plates 320. The threaded end of the clamping bolt 340 abuts against the front side of the T-shaped vertical rods 220. The clamping bolt 340 fixes the lifting position of the movable railing 300 by abutting against the front side of the T-shaped vertical rods 220.

[0033] In this embodiment, as Figure 3 As shown, the hollow post 100 has a base 130 at its bottom, which is fixed to the ground by bolts. The base 130 is used to increase the contact area and improve the overall anti-tipping ability of the guardrail. Reflective stickers 150 are glued to both the front and rear sides of the hollow post 100. The reflective stickers 150 are used to enhance the warning effect at night or in low visibility environments.

[0034] U-shaped connecting blocks 110 are provided on both the left and right sides of the hollow column 100 and near the bottom. The left and right ends of the strip base plate 210 are provided with connecting blocks 211. The connecting blocks 211 are located in the corresponding U-shaped connecting blocks 110. The U-shaped connecting blocks 110 are used to fix the connecting blocks 211, so as to realize the quick assembly and disassembly of the fixed railing 200 and the hollow column 100.

[0035] The front side of the U-shaped connecting block 110 is provided with a mounting hole 111, and a fixing bolt 120 is connected to the mounting hole 111. The threaded end of the fixing bolt 120 is threadedly connected to the front side of the mating block 211. The fixing bolt 120 fixes the mating block 211 inside the U-shaped connecting block 110 through the threaded connection.

[0036] The rear sides of multiple T-shaped vertical bars 220 are connected to multiple first strip horizontal plates 230 arranged at equal intervals. The first strip horizontal plates 230 are used to enhance the lateral stability of the fixed railing 200.

[0037] The hollow column 100 has multiple U-shaped support blocks 140 arranged at equal intervals on both the left and right sides. The end of the first strip horizontal plate 230 is located in the corresponding U-shaped support block 140. The U-shaped support block 140 is used to support the end of the first strip horizontal plate 230 and improve the overall structural strength.

[0038] Furthermore, such as Figure 6 As shown, the front sides of multiple strip vertical plates 320 are connected to multiple second strip horizontal plates 330 arranged at equal intervals. The second strip horizontal plates 330 are used to connect the strip vertical plates 320, thereby enhancing the impact resistance and rigidity of the movable railing 300.

[0039] In this embodiment, the lifting traffic construction crash barrier is used by first placing two hollow posts 100 symmetrically on both sides of the construction area and fixing them to the ground with the base 130 to increase stability. Then, the connecting blocks 211 at both ends of the strip base plate 210 of the fixed railing 200 are inserted into the U-shaped connecting blocks 110 of the hollow posts 100, and the connecting blocks 211 are locked with fixing bolts 120 through the mounting holes 111 to complete the fixing. Next, the T-shaped connecting groove 321 at the bottom of the strip vertical plate 320 of the movable railing 300 is aligned with the railing. The T-shaped vertical bar 220 of the fixed railing 200 is pushed in vertically. After adjusting to the required height, the clamping bolt 340 is tightened to secure the T-shaped vertical bar 220 to the fixed position. The stability of the fixed railing 200 is enhanced by the cooperation of the first strip horizontal plate 230 and the U-shaped support block 140 of the hollow column 100, and the impact resistance of the movable railing 300 is improved by the second strip horizontal plate 330. When adjusting the height, the clamping bolt 340 is loosened, the movable railing 300 is manually moved, and then it is tightened again. After the construction is completed, the fixing bolt 120 is removed and the railing is moved.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
