Technical Field

[0001] The utility model belongs to the field of highway maintenance equipment, in particular to a conveniently disassembled highway maintenance guardrail. Background Art

[0002] Highway maintenance refers to the routine upkeep and regular repairs of existing highways to maintain their condition and ensure safe and smooth traffic. Highway maintenance management involves daily inspections, cleaning, upkeep, and repairs. With socioeconomic development and growing transportation demands, highway maintenance management faces new challenges, requiring continuous adaptation and improvement in service quality.

[0003] During highway maintenance and repair, for the safety of pedestrians, highway guardrails need to be used as safety protection measures. Currently, most highway guardrails are welded one-piece frame guardrails. However, since the mileage of highway maintenance and repair is mostly long, the one-piece frame structure is inevitably inconvenient to carry, move, and disassemble. Even split guardrails need to be nested and installed together, and disassembly and assembly are relatively complicated, time-consuming and labor-intensive. Utility Model Content

Under normal conditions, the torsion spring drives the rotating rod to retract inward, and the torsion spring 9 provides an inward contraction force to ensure that the rotating rod has sufficient force to limit the buckle structure.

[0008] Furthermore, the rotating structure includes: a first connecting ring fixed on the side of the guardrail body, and a second connecting ring fixed on the side of the first column, the first connecting ring and the second connecting ring are matched with each other through a pin, and the first connecting ring and the second connecting ring are provided with anti-slip grooves on the corresponding surfaces, which can greatly increase the friction and prevent the first connecting ring and the second connecting ring from rotating without external force.

[0010] Furthermore, the two rod seats correspond to the torsion springs nested on the vertical shaft, the rod head is cylindrical, and the rod body is arc-shaped, which facilitates the embedding of the clip head of the snap structure.

[0011] Furthermore, the snap-on structure includes: a support connected to the first column and corresponding to the position of the slot structure, a clamping head is provided at the front end of the support, the support and the clamping head are integrated into one design, the clamping head squeezes the rotating rod of the slot structure, the rotating rod is forced to open and fix the clamping head between the rotating rods, and the rotating rod only buckles the clamping head under the action of the torsion spring to ensure the stability of the clamping head. The two adjacent guardrails are installed, and when disassembling, the user only needs to pull it apart with force, and the clamping head will break through the restraint of the rotating rod.

[0012] Furthermore, the cross section of the clamping head is diamond-shaped, which facilitates insertion and removal of the clamping slot structure.

[0013] Furthermore, the outer surfaces of the clamp head and the rod head are provided with anti-slip grooves, and the cross-sectional area of ​​the clamp head is smaller than the area between the two rotating rods.

In addition, the first column can allow the guardrail to freely adjust the rotation angle. The highway maintenance guardrail is extremely convenient to install and disassemble, saving time and effort, and the position can be adjusted at will, which greatly improves the applicability of the guardrail.

[0016] 2.

It includes: a guardrail body 1 and a pulley 2 provided at the lower end of the guardrail body 1. The pulley 2 is a universal wheel, which is convenient for the guardrail body 1 to adjust its position. One side of the guardrail body 1 is connected to the first column 4 by a rotating structure 3, and the other side of the guardrail body 1 is connected to the second column 5. The rotating structure 3 can drive the first column 4 and the second column 5 to rotate, so that the user can adjust the position and angle of adjacent guardrails, which is convenient for work. A snap structure 7 is provided on the outer side of the first column 4, and a slot structure 6 is provided on the outer side of the second column 5. The snap structures 7 of adjacent guardrail bodies 1 cooperate with the slot structure 6. When installing, the adjacent guardrail bodies 1 correspond to the first column 4 and the second column 5, and the snap structure 7 cooperates with the slot structure 6. The highway maintenance guardrail can be quickly installed and disassembled through the snap structure 7 and the slot structure 6, which is extremely convenient, saves time and effort, and the position can be adjusted at will, which greatly improves the applicability of the guardrail and is conducive to improving work efficiency.

[0024] The card slot structure 6 includes: a frame 13 fixed to one side of the second column 5, one side of the frame 13 is open, which is convenient for installing the rotating rod 10, and a vertical shaft 8 is provided inside the frame 13, on which two corresponding rotating rods 10 are embedded, and a torsion spring 9 is provided on the vertical shaft 8, which cooperates with the two rotating rods 10. In the normal state, the torsion spring 9 drives the rotating rod 10 to retract inward, and the torsion spring 9 provides an inward contraction force to ensure that the rotating rod 10 has sufficient force to limit the buckle structure 7.

[0025] The rotating structure 3 includes: a first connecting ring 301 fixed on the side of the guardrail body 1, and a second connecting ring 302 fixed on the side of the first column 4. The first connecting ring 301 and the second connecting ring 302 are matched with each other through a pin 303. The first column 4 rotates with the cooperation of the first connecting ring 301 and the second connecting ring 302. The position of the guardrail body 1 can be adjusted at will, which greatly improves the applicability of the guardrail. The corresponding surfaces of the first connecting ring 301 and the second connecting ring 302 are provided with anti-slip grooves. The anti-slip grooves can greatly increase the friction and prevent the first connecting ring 301 and the second connecting ring 302 from rotating without external force, thereby ensuring a certain stability of the guardrail body 1 and preventing it from rotating at will.

[0026] The rotating rod 10 includes: a rod seat 101 embedded in the vertical shaft 8, the rod seat 101 can rotate, and a rod shaft 102 connected to the rod seat 101, and a rod head 103 is provided at one end of the rod shaft 102. The rod seat 101, the rod shaft 102 and the rod head 103 are all integrated into one design to improve the overall strength and stability.

[0027] The two rod seats 101 correspond to the torsion springs 9 nested on the vertical shaft 8.

During installation, the clip 12 of the snap-fit ​​structure 7 squeezes the rotating rod 10 of the slot structure 6, and the rotating rod 10 is forced to open and fix the clip 12 between the rotating rods 10. Under the action of the torsion spring 9, the rotating rod 10 only buckles the clip 12 to ensure the stability of the clip 12. The two adjacent guardrails are installed. When disassembling, the user only needs to pull them apart with force, and the clip 12 breaks through the restraint of the rotating rod 12. The installation and disassembly steps are simple, the operation is quick, time-saving and labor-saving, and it is conducive to improving work efficiency.

[0029] The cross section of the clamping head 11 is diamond-shaped, which facilitates insertion and removal of the clamping slot structure 6 .

[0030] The outer surfaces of the clamping head 11 and the rod head 103 are both provided with anti-slip grooves, which can greatly increase the friction and ensure the stability of the cooperation between the buckle structure 7 and the slot structure 6. The cross-sectional area of ​​the clamping head 11 is smaller than the area between the two rotating rods 10, ensuring that the two rotating rods 10 can wrap around the clamping head 11.

[0031] When installing, the adjacent guardrail bodies 1 correspond to the first column 4 and the second column 5. The clamping head 12 of the snap structure 7 squeezes the rotating rod 10 of the slot structure 6. The rotating rod 10 is forced to open and fix the clamping head 12 between the rotating rods 10. The rotating rod 10 only buckles the clamping head 12 under the action of the torsion spring 9 to ensure the stability of the clamping head 12. The two adjacent guardrails are installed. When disassembling, the user only needs to pull them apart with force, and the clamping head 12 breaks through the restraint of the rotating rod 12.
