Description

Technical Field

[0001] This utility model relates to the field of highway maintenance technology, and in particular to a temporary guardrail support and reinforcement device for traffic diversion during highway reconstruction and expansion. Background Technology

[0002] In road-related projects such as highway maintenance, reconstruction and expansion, and expressway construction, traffic diversion is a core element in ensuring construction safety and traffic order. Temporary guardrails, as key facilities separating construction areas from traffic areas, have their installation stability and functional integrity directly related to the safety of construction personnel and passing vehicles. To achieve clear traffic guidance, speed limit, detour, and warning signs need to be installed on the guardrails simultaneously. The fixing of these signs often relies on the structural reinforcement of the guardrail itself. Therefore, the reinforcement of the back of the temporary guardrail and the installation of the signs form a closely related construction procedure.

[0003] Currently, in road construction, the reinforcement of temporary guardrails and the installation of signs generally adopt the traditional manual operation mode. The core process includes three key steps: First, construction workers use tools such as electric drills to manually drill holes at pre-set positions on the back of the guardrails. Second, bolts, angle brackets, and other components are assembled one by one to the holes to complete the assembly of the basic fixing structure. Finally, using tools such as wrenches and sockets, fixing rods are inserted through the reserved holes of adjacent guardrails to achieve a rigid connection between the guardrails. The signs need to be additionally fixed to the reinforced guardrails with cable ties or special clamps. This traditional construction method has many prominent problems and is no longer suitable for the efficient and safe operation requirements of modern road construction. From the perspective of construction efficiency, rework is frequent due to factors such as uneven guardrail strength and limited operating space during manual drilling. In addition, the splicing of components and the installation of fixing rods all rely on manual operation. Furthermore, after construction, it is not convenient to disassemble, which significantly increases labor costs.

[0004] To address this issue, a temporary guardrail support and reinforcement device for highway reconstruction and expansion is proposed to solve the problems existing in the current technology. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems by providing a temporary guardrail support and reinforcement device for highway reconstruction and expansion. This utility model uses installation components to sequentially attach pre-installed fixing rods and fixing trusses to two temporary guardrails, providing a stable connection. It eliminates the tedious steps of traditional manual drilling, calibration, and cleaning, achieving rapid plug-in installation of the fixing rods through pre-set slots and installation components. The fixing time for a single set of temporary guardrails is reduced from the traditional 15-20 minutes to 2-3 minutes, significantly improving efficiency. To achieve the above-mentioned utility model objectives, the technical solution adopted is as follows: According to one aspect of this utility model, a temporary guardrail support and reinforcement device for traffic diversion in highway reconstruction and expansion is provided, including temporary guardrails, two of which are arranged horizontally side by side, each of which has a drainage outlet in the middle of its lower end, and a reinforcing frame between the two temporary guardrails. Each of the temporary guardrails has four slots, which are arranged in pairs on the left and right sides of the temporary guardrail, with two slots on the same side arranged vertically in sequence. Each slot has a fixing rod, and a fixing truss is provided between two fixing rods on the same horizontal line. An installation component is provided between each fixing rod and the temporary guardrail for convenient installation and disassembly of the fixing rod.

[0006] Preferably, the installation assembly includes a fixing component and a connector. The fixing component includes two fixing plates disposed on each temporary guardrail, and each fixing plate is disposed above a corresponding slot. The fixing plate has a cavity and an insertion port that communicates with the cavity. A sleeve is disposed in the cavity and extends outward through the insertion port. The sleeve is coaxially arranged with the slot. A connector is disposed in the sleeve for installing and removing the fixing rod.

[0007] Preferably, the connector includes a collet disposed inside the sleeve. The collet is hollow and has a contact inclined ring on its top outer circumference. The upper end of the sleeve has an internal thread. The upper end of the sleeve has a gasket with a through groove arranged coaxially with the insertion port. The lower end of the gasket has a pressing inclined surface that cooperates with the contact inclined ring. The outer circumference of the gasket has an external thread that meshes with the internal thread.

[0008] Preferably, the chuck has four slots, and each slot extends downward to a distance of 1-2 mm from the bottom of the chuck, so that the chuck can clamp and open.

[0009] Preferably, the bottom circumference of the sleeve is evenly distributed with multiple limiting blocks, and the bottom of the chuck is provided with multiple limiting grooves, and the multiple limiting grooves cooperate with the multiple limiting blocks.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. The present invention relates to a temporary guardrail support and reinforcement device for highway reconstruction and expansion. Workers can pre-install fixed rods and fixed trusses. After the temporary guardrails are installed on the ground, workers can use the installation components to sequentially install the pre-installed fixed rods and fixed trusses onto the two temporary guardrails, thus connecting and stabilizing the guardrails. It eliminates the tedious steps of traditional manual drilling, calibration, and cleaning. Through the pre-set slots and installation components, the fixed rods can be quickly installed by plugging them in. The fixing time for a single set of temporary guardrails is reduced from the traditional 15-20 minutes to 2-3 minutes, improving efficiency.

Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of the utility model, and these aspects can be achieved even without these specific details.

[0014] Please see Figures 1 to 5 This utility model provides a temporary guardrail support and reinforcement device for traffic diversion in highway reconstruction and expansion, and the technical solution is as follows: The system includes temporary guardrails 1, with two temporary guardrails 1 arranged horizontally side by side. Each temporary guardrail 1 has a drainage outlet 2 at the lower center, and a reinforcing frame 3 is provided between the two temporary guardrails 1. Each temporary guardrail 1 has four slots 4, which are arranged in pairs on the left and right sides of the temporary guardrail 1. Two slots 4 on the same side are arranged vertically in sequence. Each slot 4 has a fixing rod 5, and a fixing truss 6 is provided between two fixing rods 5 on the same horizontal line. An installation component is provided between each fixing rod 5 and the temporary guardrail 1 for convenient installation and disassembly of the fixing rod 5.

[0015] Workers can pre-install the fixing rods 5 and fixing trusses 6. After the temporary guardrail 1 is installed on the ground, workers can use the installation components to install the fixed rods 5 and fixing trusses 6 onto the two temporary guardrails 1 in sequence, which will connect and stabilize the guardrails. This eliminates the tedious steps of traditional manual drilling, calibration, and cleaning. The fixed rods 5 can be quickly installed by plugging them in through the pre-set slots 4 and the installation components. The fixing time for a single set of temporary guardrails 1 is reduced from the traditional 15-20 minutes to 2-3 minutes, which improves efficiency. At the same time, the fixing trusses 6 simultaneously complete the lateral reinforcement of adjacent guardrails, realizing the integration of installation and reinforcement, which improves the overall efficiency.

[0016] The installation assembly includes a fixing component and a connector. The fixing component includes two fixing plates 7 disposed on each temporary guardrail 1, and each fixing plate 7 is disposed above a corresponding slot 4. A cavity 8 is formed inside the fixing plate 7, and an insertion port 9 is formed on the fixing plate 7, and the insertion port 9 communicates with the cavity 8. A sleeve 10 is provided inside the cavity 8, and the sleeve 10 extends outward through the insertion port 9. The sleeve 10 is coaxially arranged with the slot 4. A connector is provided inside the sleeve 10 for installing and removing the fixing rod 5.

[0017] The sleeve 10, coaxially arranged with the fixing plate 7 and the slot 4, forms a directional guiding structure. When the fixing rod 5 is inserted, it can be precisely aligned with the slot 4 along the sleeve 10 without additional hole calibration, completely avoiding the deviation problem of traditional manual drilling, ensuring the consistency of the installation position of the fixing rod 5, simplifying the installation operation, further shortening the installation time of a single set of guardrails, and improving construction efficiency. The sleeve 10 provides a stable installation carrier for the connector. The connector can adopt convenient structures such as quick locking and threaded engagement. After the fixing rod 5 is inserted into the slot 4, it can be quickly fixed through the connector in the sleeve 10 without additional auxiliary tools. When disassembling, only the connector needs to be operated to unlock, realizing the non-destructive separation of the fixing rod 5 from the guardrail, improving the efficiency of installation and disassembly.

[0018] The connector includes a collet 11 disposed inside the sleeve 10. The collet 11 is hollow and has a contact inclined ring 12 on its top outer circumference. The upper end of the sleeve 10 has an internal thread 13 and a cover 14. The cover 14 has a through groove 15 arranged coaxially with the insertion port 9. The lower end of the cover 14 has a pressing inclined surface 17 that cooperates with the contact inclined ring 12. The outer circumference of the cover 14 has an external thread 16 that meshes with the internal thread 13. The collet 11 has four slots 18, and each slot 18 extends downward to a distance of 1-2 mm from the bottom of the collet 11. The collet 11 can clamp and open.

[0019] The collet 11 features a hollow structure with four downward-extending slots 18. The 1-2mm bottom connection section ensures the structural strength of the collet 11 while providing ample elastic opening and clamping stroke, making it compatible with fixing rods 5 of different diameters (with a compatibility error range of ±0.5mm). Through the wedge-shaped engagement of the contact ring 12 and the extrusion slope 17, the axial pressure is converted into radial clamping force when the cover 14 is rotated, achieving multi-point uniform clamping of the fixing rod 5. Utilizing the meshing structure of the external thread 16 of the cover 14 and the internal thread 13 of the sleeve 10, the collet 11 can be clamped and released simply by manually rotating the cover 14, without the need for additional tools such as wrenches or sleeves 10. This allows for independent operation by a single person, reducing the locking / unlocking time of a single fixing rod 5 to less than 30 seconds. Compared to the rust and adhesion and forced prying required for disassembling traditional fixing rods 5, this structure allows for easy unloading by simply turning, avoiding the cumbersome, time-consuming, and laborious disassembly process of traditional methods.

[0020] The sleeve 10 has multiple limiting blocks 19 evenly distributed around its bottom circumference, and the chuck 11 has multiple limiting grooves 20 at its bottom, with the multiple limiting grooves 20 cooperating with the multiple limiting blocks 19.

[0021] The limiting block 19 at the bottom of the sleeve 10 and the limiting groove 20 at the bottom of the chuck 11 form a circumferential positioning structure, which can completely limit the rotation of the chuck 11 within the sleeve 10, preventing the chuck 11 from rotating synchronously with the pad 14 when the rotating pad 14 applies clamping force, ensuring that the contact inclined ring 12 and the extrusion inclined surface 17 always maintain precise contact, and efficiently converting axial pressure into radial clamping force; and through the limitation of the limiting groove 20 and the limiting block 19, the chuck 11 and the sleeve 10 are detachably connected, and the chuck 11 can be replaced when it is worn, ensuring the stability of clamping the fixed rod 5.

[0022] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
