Description

Technical Field

[0001] This utility model relates to the field of traffic guardrail technology, and in particular to an assembled guardrail for traffic guidance. Background Technology

[0002] Traffic diversion plays an important role in the construction of main municipal roads. The main contents of traffic diversion include traffic diversion in the surrounding road network during the construction period, while reserving at least 5 meters wide road surface on each side outside the construction enclosure area to meet the travel needs of public transportation and residents, enterprises and institutions along the route, and to ensure that traffic is not interrupted. Road guardrails are usually used for enclosure during the traffic diversion process.

[0003] Chinese invention patent CN115341803B discloses an assembled guardrail and its usage method. The assembled guardrail includes: several bases arranged opposite each other; insertion holes opened vertically in the bases; support blocks slidably disposed in the insertion holes; two adjusting rods rotatably connected in an X shape, one end of the adjusting rod sliding on the support block and the other end sliding on the bottom surface of the insertion hole; a connecting rod rotatably connected at one end to an adjusting rod and the other end protruding from the side of the base; a support rod vertically connected to the end of the connecting rod away from the adjusting rod and for contact with the ground; a post inserted into the insertion hole and with its bottom contacting the support block; and a protective member detachably disposed between two adjacent posts.

[0004] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: Traffic diversion guardrails are a temporary protective measure. After use, the guardrails must be removed and transported to other locations that require traffic diversion guardrails. The aforementioned technologies use protective frames and connecting plates for shielding and protection. Generally, the area to be protected is relatively large, which requires the connecting plates and protective frames to be quite long. It is difficult to move the entire traffic diversion guardrail. If the connecting plates and protective frames are disassembled and moved, the components of the traffic diversion guardrail need to be reassembled for reuse, which is time-consuming and labor-intensive. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides an assembled guardrail for traffic guidance.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a traffic guidance assembled guardrail, including an installation component and an electric flatbed vehicle set at the bottom of the installation component. The installation component is provided in two sets, and a guardrail component is provided between the two sets of installation components. The guardrail component is composed of multiple sets of guardrail units connected in sequence. The guardrail unit includes a first protective frame. The first protective frames of two adjacent guardrail units are hinged to each other, and the two hinges corresponding to the first protective frame are located on opposite sides of the first protective frame.

[0007] By adopting the above technical solution, after using the device, driving two sets of electric flatbed carts brings the two sets of installation components closer together. Since the first protective frames on adjacent guardrail units are hinged together, multiple sets of first protective frames fold and approach each other until they are pressed together, thus reducing the length of the guardrail. When short-distance movement of the assembled guardrail is required, the assembled guardrail can be transported by controlling the synchronous movement of the two sets of electric flatbed carts. When long-distance movement of the assembled guardrail is required, the folded assembled guardrail needs to be loaded onto the carts and transported. This eliminates the cumbersome operation of disassembling the components of the guardrail for transportation, as required by traditional technology, reducing the difficulty of handling and saving time and effort.

[0008] Furthermore, adjacent first protective frames are provided with interconnected mounting slots on their close-to-each-slot frames. The first protective frames of adjacent guardrail units are limited by a limiting component, which includes a limiting plate rotatably installed in the mounting slot. After the two adjacent first protective frames are unfolded, the limiting plate abuts against the inner wall of the mounting slot on the adjacent first protective frame.

[0009] By adopting the above technical solution, when the assembled guardrail is unfolded, the limiting plate is rotated toward the mounting groove on the adjacent first guardrail until the side wall of the limiting plate abuts against the inner side wall of the mounting groove on the adjacent first guardrail. The frictional resistance generated by the abutment of the limiting plate and the mounting groove helps to improve the stability of the two first guardrails after unfolding.

[0010] Furthermore, each of the limiting plates is fixed with a magnet that is magnetically attracted to the first protective frame.

[0011] By adopting the above technical solution, the attraction between the magnet and the first protective frame further improves the stability of the limiting plate in limiting the first protective frame after it is unfolded.

[0012] Furthermore, each set of mounting components includes a lower mounting block fixed to the top of the electric flatbed vehicle and an upper mounting block disposed above the lower mounting block. The upper mounting block has a sliding groove on its top. The mounting component also includes a connecting block fixed to the top of the lower mounting block and slidingly engaged with the sliding groove. One of the lower mounting blocks is provided with a control component for controlling the lifting and lowering of the upper mounting block. The guardrail unit also includes a second guardrail disposed below the first guardrail. The second guardrail has a mounting hole on its top. The guardrail unit also includes a connecting rod fixed to the bottom of the first guardrail and slidingly engaged with the mounting hole.

[0013] By adopting the above technical solution, during the process of adjusting the two mounting components to approach each other, the upper mounting block is driven to descend by the control component. Since the connecting block fixed at the top of the lower mounting block slides with the slide groove on the upper mounting block, and the connecting rod fixed on the first protective frame slides with the mounting hole on the second protective frame, the upper and lower mounting blocks approach each other, the first and second protective frames approach each other, and finally the bottom of the upper mounting block and the top of the lower mounting block fit together, and the bottom of the first protective frame and the top of the second protective frame fit together. This reduces the volume of the assembled guardrail and helps to improve the stability of the folded assembled guardrail in the transport vehicle.

[0014] Furthermore, the control assembly includes a connecting plate fixed to the lower mounting block, a mounting shell fixed to the upper mounting block and slidingly engaged with both ends of the connecting plate, a threaded rod rotatably mounted in the mounting shell, and a lifting motor fixed to the mounting shell and driving the threaded rod to rotate. The threaded rod passes through the connecting plate and is screwed to the threaded rod of the connecting plate. The first protective frame located on both sides of the guardrail unit is hinged to the upper mounting block, and the second protective frame located on both sides of the guardrail unit is hinged to the lower mounting block.

[0015] By adopting the above technical solution, the lifting motor rotates the threaded rod after it starts working. Since the threaded rod is threadedly connected to the connecting plate, the threaded rod, the mounting shell, the lifting motor, the upper mounting block and the first protective frame can be raised and lowered, which facilitates the retraction of the assembled guardrail.

[0016] Furthermore, a limiting rod is rotatably mounted on one of the upper mounting blocks, and a limiting post is fixed on the other upper mounting block. The limiting rod is provided with a slot near its end that engages with the limiting post.

[0017] By adopting the above technical solution, when the assembled guardrail is fully folded, the limiting rod is rotated and the slot is locked on the limiting post, which can limit the two sets of upper mounting blocks and ensure the stability of the upper mounting blocks during transportation.

[0018] Furthermore, a rubber sheet is fixed to the inner wall of the slot.

[0019] By adopting the above technical solution, when the slot and the limiting post are connected, the rubber plate is in a state of compression deformation. The elastic force generated by the rubber plate acts on the limiting post, reducing the probability of vibration during transportation and causing the limiting rod to fall off the limiting post.

[0020] In summary, this utility model has the following beneficial effects: In this application, after using the device, driving two sets of electric flatbed carts brings the two sets of installation components closer together. Since the first protective frames on adjacent sets of guardrail units are hinged to each other, multiple sets of first protective frames fold and approach each other until they are pressed together, thereby reducing the length of the guardrail. When the assembled guardrail needs to be moved a short distance, the assembled guardrail can be transported by controlling the synchronous movement of the two sets of electric flatbed carts. When the assembled guardrail needs to be moved a long distance, the folded assembled guardrail needs to be loaded onto the vehicle and transported, changing the cumbersome operation of disassembling the components of the guardrail for transportation in the traditional technology, reducing the difficulty of handling, and saving more time and effort.

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] like Figure 1-5As shown in the figure, this application discloses a traffic guidance assembly guardrail, including an installation component 1, an electric flatbed trolley 2, a guardrail component 3, a control component 6, and a limiting component 5. The installation component 1 is mounted on the electric flatbed trolley 2, which is driven by a motor (specifically, the motor drives the rotating shaft on the mounting base of the electric flatbed trolley 2 to rotate, so that both rollers on the rotating shaft rotate; this part belongs to the prior art, and the motor, rotating shaft, and rollers are not shown in the figure).

[0029] In this embodiment, there are two electric flatbed carts 2, and two sets of mounting components 1. Each set of mounting components 1 includes a lower mounting block 11, an upper mounting block 12, and a connecting block 13. The bottom of the lower mounting block 11 is fixed to the top of the electric flatbed cart 2, and a sliding groove (not shown in the figure) is provided on the top of the lower mounting block 11. The upper mounting block 12 is disposed above the lower mounting block 11, and the top of the connecting block 13 is fixed to the bottom of the upper mounting block 12, and the connecting block 13 slides in conjunction with the sliding groove.

[0030] The guardrail assembly 3 is located between two sets of mounting assemblies 1. The guardrail assembly 3 is composed of multiple sets of guardrail units 31 connected sequentially. Each guardrail unit 31 includes a first protective frame 311, a second protective frame 312, and a connecting rod 313. The first protective frames 311 of two adjacent guardrail units 31 are hinged to each other, with the two corresponding hinges of the first protective frame 311 located on opposite sides of the first protective frame 311. The first protective frame 311 near the upper mounting block 12 is hinged to the upper mounting block 12. The second protective frame 312 is located below the first protective frame 311. The second protective frames 312 of two adjacent guardrail units 31 are hinged to each other, with the two corresponding hinges of the second protective frame 312 located on opposite sides of the second protective frame 312. The second protective frame 312 near the lower mounting block 11 is hinged to the lower mounting block 11. A mounting hole (not shown in the figure) is provided at the top of the second protective frame 312. The connecting rod 313 is fixed to the bottom of the first protective frame 311 and slides with the mounting hole.

[0031] The control component 6 is mounted on one of the lower mounting blocks 11. The control component 6 includes a connecting plate 61, a mounting shell 62, a threaded rod 63, and a lifting motor 64. The connecting plate 61 is fixed to the lower mounting block 11. The mounting shell 62 is fixed to the upper mounting block 12, and its inner wall slides against both ends of the connecting plate 61. The threaded rod 63 is rotatably mounted inside the mounting shell 62, passing through the connecting plate 61 and threadedly connected to it. The lifting motor 64 is fixed to the mounting shell 62, and its output end is fixed to the threaded rod 63 to drive the threaded rod 63 to rotate. After using the device, drive the two sets of electric flatbed carts 2 to bring the two sets of mounting components 1 closer together. Since the first protective frames 311 on the two adjacent sets of guardrail units 31 are hinged to each other, multiple sets of first protective frames 311 fold and approach each other until they fit together, thereby reducing the length of the guardrail. Then turn on the lifting motor 64. The output end of the lifting motor 64 drives the threaded rod 63 to rotate. Since the threaded rod 63 is threadedly connected to the connecting plate 61 and the connecting plate 61 is slidably engaged with the mounting shell 62, the threaded rod 63, the mounting shell 62, the lifting motor 64, the upper mounting block 12 and the first protective frame 311 all descend. Since the connecting block 13 fixed at the top of the lower mounting block 11 slides with the groove on the upper mounting block 12, the connecting block 13 is engaged with the groove on the upper mounting block 12. The system is dynamically coordinated, with the connecting rod 313 fixed on the first protective frame 311 and the mounting holes on the second protective frame 312 slidingly engaged. The upper mounting block 12 and the lower mounting block 11 approach each other, as do the first protective frame 311 and the second protective frame 312. Finally, the bottom of the upper mounting block 12 and the top of the lower mounting block 11 fit together, and the bottom of the first protective frame 311 and the top of the second protective frame 312 fit together. This reduces the volume of the assembled guardrail and lowers its center of gravity (lowering the center of gravity improves the stability of the assembled guardrail during transport). When short-distance movement of the assembled guardrail is required, it can be transported by controlling the synchronous movement of two sets of electric flatbed trucks. When long-distance movement of the assembled guardrail is required, the folded assembled guardrail needs to be loaded onto a vehicle for transport. This eliminates the cumbersome operation of disassembling the components of the guardrail for transport in traditional technology, reducing the difficulty of handling and saving time and effort.

[0032] Two adjacent first protective frames 311 are provided with interconnected mounting slots 4 on their close-to-each-slot frames. A limiting component 5 is used to limit the first protective frames 311 of the two adjacent guardrail units 31. The limiting component 5 includes a limiting plate 51 and a magnet 52. The limiting plate 51 is rotatably installed in the mounting slot 4. After the two adjacent first protective frames 311 are unfolded, the limiting plate 51 abuts against the inner wall of the mounting slot 4 on its adjacent first protective frame 311. The magnet 52 is fixed to the end of the limiting plate 51 away from its rotation axis. The magnet 52 corresponds one-to-one with the limiting plate 51, and the magnet 52 is magnetically attracted to the first protective frame 311. When the assembled guardrail is unfolded, the limiting plate 51 is rotated toward the mounting groove 4 on the adjacent first protective frame 311 until the side wall of the limiting plate 51 abuts against the inner side wall of the mounting groove 4 on the adjacent first protective frame 311. The frictional resistance generated by the abutment between the limiting plate 51 and the mounting groove 4, as well as the attraction generated between the magnet 52 and the first protective frame 311, helps to improve the stability of the two first protective frames 311 after unfolding.

[0033] One of the upper mounting blocks 12 has a limit rod 7 rotatably mounted on it, and the other upper mounting block 12 has a limit post 8 fixed on it. Near its end, the limit rod 7 has a groove 71 that engages with the limit post 8. A rubber sheet 72 is fixed to the inner wall of the groove 71. When the assembled guardrail is fully folded, rotating the limit rod 7 causes the groove 71 to engage with the limit post 8. The limit post 8 then deforms the rubber sheet 72, generating an elastic force that acts on the limit post 8. This limits the movement of both sets of upper mounting blocks 12, ensuring the stability of the assembled guardrail during transportation.

[0034] The working principle of the traffic guidance modular guardrail in this embodiment is as follows: After using the device, drive two sets of electric flatbed trucks 2 to bring the two sets of mounting components 1 closer together. Since the first protective frames 311 on the adjacent guardrail units 31 are hinged to each other, multiple sets of first protective frames 311 fold and approach each other until they fit together, thereby reducing the length of the guardrail. Then, turn on the lifting motor 64. The output end of the lifting motor 64 drives the threaded rod 63 to rotate. Since the threaded rod 63 is threadedly connected to the connecting plate 61, and the connecting plate 61 is slidably engaged with the mounting shell 62, the threaded rod 63, the mounting shell 62, the lifting motor 64, the upper mounting block 12 and the first protective frame 311 all descend. Since the connecting block 13 fixed at the top of the lower mounting block 11 and the connecting block 13 are connected to the lower mounting block 11, the lower mounting block 12 and the lower mounting block 12 are connected to ... The upper mounting block 12 slides along the groove, and the connecting rod 313 fixed on the first protective frame 311 slides along the mounting hole on the second protective frame 312. The upper mounting block 12 and the lower mounting block 11 move closer to each other, as do the first protective frame 311 and the second protective frame 312. Finally, the bottom of the upper mounting block 12 and the top of the lower mounting block 11 fit together, and the bottom of the first protective frame 311 and the top of the second protective frame 312 fit together. This reduces the volume of the assembled guardrail and lowers its center of gravity (lowering the center of gravity improves the stability of the assembled guardrail during transport). When the assembled guardrail needs to be moved a short distance, it can be transported by controlling the synchronous movement of two sets of electric flatbed carts 2. When the assembled guardrail needs to be moved a long distance, it needs to be loaded onto a vehicle and transported. This changes the cumbersome operation of disassembling the components of the guardrail for transport in traditional technology, reducing the difficulty of handling and saving time and effort.

[0035] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
