Description

Technical Field

[0001] This utility model relates to the field of railing technology, and in particular to a new type of highway railing. Background Technology

[0002] Highway barriers are an important part of traffic management facilities. Their core function is to control and protect vehicles through physical barriers, restricting the passage of unauthorized vehicles or vehicles that have not paid fees or been inspected.

[0003] Chinese patent discloses a modular electric guardrail mechanism for highways (authorization announcement number CN212026024U). This patented technology includes a main housing with a guardrail on one side of its top. The guardrail consists of a power plate, end plates, and multiple modular blocks. Each modular block has a connecting groove with a "C"-shaped cross-section at one end and a protrusion that engages with the connecting groove at the other end. Both the connecting groove and the protrusion have threaded holes for external bolts to pass through. A limit block is fixed to the surface of the protrusion, and a recessed hole for the limit block to be inserted into the inner wall of the connecting groove. This modular design transforms the existing one-piece guardrail into a modular structure, allowing for adjustments based on the actual width of the road, avoiding situations where it becomes unusable due to intersection reconstruction or production errors. The flexibility of use is greatly improved. The designed position markings ensure more precise placement of reflective strips, facilitating their application.

[0004] However, this patent still has shortcomings. While it is suitable for road conditions of varying widths, the guardrails primarily rely on a motor for Y-axis rotation. This makes them susceptible to damage from impacts, potentially even damaging the motor output shaft and control system, rendering them unable to stop vehicles during maintenance. Therefore, those skilled in the art have proposed a novel highway guardrail to address the problems described in the background section. Utility Model Content

[0005] 1. Technical Solution

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a novel highway guardrail, comprising a mounting frame, a control box, a guardrail body, a first mounting shaft, a hydraulic rod, and a second mounting shaft. The mounting frame is open on three sides, and a rotating seat is installed inside the mounting frame. The control box is installed inside the rotating seat. The first mounting shaft is rotatably mounted inside the rotating seat at both the upper and lower ends of the control box. A torsion spring is sleeved on the outer side of the first mounting shaft, with its two ends connected to the rotating seat and the control box, respectively. The control box contains symmetrically distributed bearing seats, and the second mounting shaft is rotatably mounted inside the bearing seats. A guide wheel is sleeved on the outer wall of the second mounting shaft, and a pull rope with one end fixedly connected to the guide wheel is wound around the outer wall of the guide wheel. A connecting block is provided at one end of the pull rope. A torsion spring is sleeved on the outer side of the second mounting shaft, with its two ends connected to the guide wheel and the bearing seat, respectively. An electric hydraulic rod with its telescopic end connected to the connecting block is installed inside the control box.

[0008] Furthermore, the control box is equipped with symmetrically distributed guide rails, and the lower end of the connecting block is equipped with a slider that is slidably installed on the outer wall of the guide rails;

[0009] Specifically, when the connecting block moves, it slides on the outer wall of the guide rail via a slider, thus guiding the movement path of the connecting block. The stroke force exerted by the connecting block on the pull rope is consistent with that of the electro-hydraulic rod.

[0010] Furthermore, a semi-ring rod is provided at the upper end of the mounting shaft, a semi-ring tube is sleeved on the outer side of one end of the semi-ring rod, and a piston is provided at one end of the semi-ring rod that is slidably installed inside the semi-ring tube.

[0011] Specifically, when the semi-ring rod rotates with the mounting shaft, it drives the piston to slide inside the semi-ring tube, squeezing the hydraulic oil inside the plate ring tube.

[0012] Furthermore, a gap is provided between the piston and the inner wall of the semi-ring tube, one end of the semi-ring tube is closed, and a support rod connected to the rotating seat is provided at the lower end of the semi-ring tube. A sealing ring is embedded in the open end of the semi-ring rod, and the semi-ring rod is slidably installed inside the sealing ring.

[0013] Specifically, when the hydraulic oil is squeezed, it flows through the gap and applies resistance to the piston. The semi-ring rod slides inside the seal ring to prevent hydraulic oil leakage. The semi-ring tube is fixed to the rotating seat by the support rod, providing sliding support for the piston and the semi-ring rod.

[0014] Furthermore, the railing body is tubular, and an adjusting rod is slidably installed inside the railing body;

[0015] Specifically, the guardrail body is hollow inside, allowing the adjusting rod to slide inside the guardrail body and adjust the interception length to fit the width of different roads.

[0016] Furthermore, the outer wall of the adjusting rod is provided with an installation groove, the inner wall of the installation groove is provided with a spring, the inside of the railing body is provided with equally spaced through holes, and one end of the spring is provided with a retaining bead that engages with the inside of the through hole;

[0017] Specifically, when the elastic support bead is inside the through hole, the adjusting rod is fixed. The adjusting rod is positioned after adjustment by the elastic support bead being inside the through hole at different positions.

[0018] 2. Beneficial effects

[0019] Compared with existing technologies, the advantages of this utility model are:

[0020] This invention utilizes an electro-hydraulic rod to drive a pull rope in linear motion, which in turn rotates a second mounting shaft and applies a torsional force to a second torsion spring. The second mounting shaft then rotates the barrier body along the Y-axis, controlling the passage and stopping of vehicles. If a vehicle fails to stop in time and impacts the barrier body, the impact force acts on the first torsion spring, causing the barrier and control box to rotate along the X-axis. This prevents the electrical structure driving the barrier from being directly affected by the impact force, protecting both the electrical structure and the barrier body. The barrier body is passively protected from impact, and the torsional elasticity of the first torsion spring acting on the control box pushes the barrier body back to its original position. This reduces the likelihood of direct damage rendering the barrier unusable, allowing it to continue fulfilling its road control function.

[0021] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Those skilled in the art can make similar extensions without departing from the spirit of the present invention.

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0036] Example 1

[0037] Please see Figure 1-7As shown, this embodiment is a new type of highway guardrail, including a mounting frame 1, a control box 3, a guardrail body 7, a mounting shaft 4, a hydraulic rod, and a mounting shaft 17. The mounting frame 1 is open on three sides. A rotating seat 2 is set inside the mounting frame 1. The control box 3 is set inside the rotating seat 2. The upper and lower ends of the control box 3 are both equipped with mounting shafts 4 that are rotatably installed inside the rotating seat 2. Torsion springs 5 ​​are sleeved on the outside of the mounting shafts 4, with their two ends connected to the rotating seat 2 and the control box 3 respectively. The control box 3 is equipped with symmetrically distributed bearing seats 18. The mounting shaft 17 is rotatably installed inside the bearing seats 18. A guide wheel 15 is sleeved on the outer wall of the mounting shaft 17. A pull rope 14 is wound on the outer wall of the guide wheel 15, with one end fixedly connected to the guide wheel 15. A connecting block 11 is set on one end of the pull rope 14. Torsion springs 16 are sleeved on the outside of the mounting shaft 17, with their two ends connected to the guide wheel 15 and the bearing seat 18 respectively. An electric hydraulic rod 10 with its telescopic end connected to the connecting block 11 is set inside the control box 3.

[0038] The control box 3 is equipped with symmetrically distributed guide rails 13, and the lower end of the connecting block 11 is equipped with a slider 12 that is slidably installed on the outer wall of the guide rails 13.

[0039] In this embodiment, under normal use, the electric hydraulic rod 10 drives the connecting block 11 to make linear displacement along the guide rail 13 through telescopic movement. The connecting block 11 pulls the rope 14 to drive the mounting shaft 17 to rotate, thereby causing the guide wheel 15 sleeved on the outer wall of the mounting shaft 17 to rotate synchronously. At this time, the torsion spring 16 is twisted and stores energy, driving the guardrail body 7 to rotate around the Y-axis from 0 to 90°, realizing the switching control of road passage and interception.

[0040] When a vehicle accidentally impacts the guardrail body 7, the impact force is first transmitted to the torsion spring 5 through the mounting shaft 4, causing it to undergo elastic deformation and absorb some of the impact kinetic energy. At the same time, the control box 3 drives the guardrail body 7 to rotate around the X-axis. At this time, the semi-ring rod 9 rotates synchronously with the mounting shaft 4, pushing the piston 25 to squeeze the hydraulic oil in the semi-ring tube 6. The hydraulic oil forms a damping effect through the preset gap, further converting the impact energy into heat energy for consumption. This dual-axial buffer mechanism effectively avoids the impact force from directly acting on the motor and transmission system, protecting the core control components from damage. After the impact, the bidirectional action of the elastic restoring force of the torsion spring 5 and the hydraulic damping causes the guardrail body 7 to automatically reset to the working position, ensuring the continuity of the road control function.

[0041] Because the road torsion spring 5 is damped, the mounting shaft 4 rotates smoothly during the reset rotation process, avoiding secondary damage caused by the instantaneous reset of the mounting shaft 4. The safety of using the mounting shaft 4 and the railing body 7 is improved.

[0042] The hydraulic buffer system transforms rigid impacts into controllable hydraulic damping motion, preventing structural component breakage. Compared to traditional electric guardrails, its impact resistance is improved, making it particularly suitable for high-load usage scenarios such as highway toll stations and checkpoints. While ensuring road control efficiency, it significantly reduces maintenance costs after impacts.

[0043] Example 2

[0044] Please see Figure 1-7 As shown, a semi-ring rod 9 is provided at the upper end of the mounting shaft 4, a semi-ring tube 6 is sleeved on the outer side of one end of the semi-ring rod 9, and a piston 25 is provided at one end of the semi-ring rod 9 and slidably installed inside the semi-ring tube 6.

[0045] A gap is provided between the piston 25 and the inner wall of the semi-ring tube 6. One end of the semi-ring tube 6 is closed. A support rod 23 connected to the rotating seat 2 is provided at the lower end of the semi-ring tube 6. A sealing ring 24 is embedded in the opening of one end of the semi-ring rod 9. The semi-ring rod 9 is slidably installed inside the sealing ring 24.

[0046] The railing body 7 is tubular, and an adjusting rod 8 is slidably installed inside the railing body 7.

[0047] The outer wall of the adjusting rod 8 is provided with a mounting groove 20, the inner wall of the mounting groove 20 is provided with a spring 21, the inside of the railing body 7 is provided with equally spaced through holes 19, and one end of the spring 21 is provided with a locking bead 22 that is engaged with the inside of the through hole 19.

[0048] In this embodiment, squeezing the locking bead 22 and rotating the adjusting rod 8 causes the locking bead 22 to be misaligned with the through hole 19. After reaching the appropriate length for the road width, rotating the adjusting rod 8 moves the locking bead 22 to the corresponding position of the through hole 19. After the locking bead 22 is inside the through hole 19, it positions the adjusting rod 8. The guardrail body 7 adopts a telescopic structure. By pressing the locking bead 22 to compress the spring 21, it is disengaged from the current through hole 19, and the adjusting rod 8 can be pulled to the required length. After release, the spring 21 pushes the locking bead 22 to embed into the corresponding through hole 19 to complete the positioning, realizing the adjustment required to adapt to the road width and adapting to different road conditions. The adjustable guardrail design expands the equipment's adaptation error range. In addition, reflective strips are attached to the outer wall of the adjusting rod 8 and the guardrail body 7. The reflective strips enhance the warning effect for vehicles. This technical solution effectively solves the technical problem of poor adaptability.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0050] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
