Description

Technical Field

[0001] This utility model relates to the field of safety guardrail technology, and in particular to road construction safety guardrails that are easy to assemble. Background Technology

[0002] During road construction, safety barriers are needed to create a closed construction environment to ensure safety and order, isolating the construction area from the outside world, restricting and protecting activities within a specific area, and serving as a reminder to pedestrians and vehicles to avoid them accidentally entering the construction area and causing damage. This achieves the purpose of eliminating or mitigating safety hazards. However, the barriers are integral and cannot be folded up, requiring a lot of space during transportation, making them inconvenient to carry and transfer, increasing transportation costs and difficulties. The height of the barriers is mostly fixed, making it impossible to align and assemble them on uneven ground, requiring shims and digging to maintain levelness. The height cannot be flexibly adjusted according to the actual site conditions, resulting in poor applicability.

[0003] With the rapid development of the construction industry, road construction safety guardrails are also constantly evolving towards greater convenience and practicality. To address the problems of traditional guardrails, researchers are dedicated to developing road construction safety guardrails that are easy to assemble, height-adjustable, and convenient to transport and store, thereby improving construction efficiency, reducing construction costs, and better meeting the safety protection needs during road construction. However, in the current process of road construction safety guardrails, when a part of the guardrail is damaged and needs to be replaced, the difficulty in splicing means that the process of disassembling and installing new parts is very complicated, increasing the difficulty and time cost of maintenance, thus reducing the efficiency of use. Utility Model Content

[0031] Please see the appendix Figure 1 - Appendix Figure 3 An embodiment of this utility model provides a road construction safety guardrail that is easy to assemble, including an elongated plate 4. Support rods 1 are fixedly connected to the left and right sides of the outer wall of the elongated plate 4. Long rods 11 are fixedly connected to the bottom of the support rods 1. A connecting plate 8 is rotatably connected to the middle of the outer wall of the right long rod 11. A connecting post 20 is fixedly connected to the middle of the right side of the connecting plate 8. A locking hole 16 is opened at the middle of the top of the connecting post 20. An elongated plate 18 is fixedly connected to the outer wall of the left long rod 11. A locking post 19 is fixedly connected to the left end of the elongated plate 18. The outer wall of the locking post 19 engages with the inner side of the locking hole 16. Threaded knobs 12 are threadedly connected to the front sides of the connecting plate 8 and the connecting plate 18. A stabilizing mechanism 2 is provided at the bottom of the long rod 11. The stabilizing mechanism 2 is used to stabilize the guardrail. Reinforcing strips 7 and 6 are fixedly connected to the bottom left and right sides of the elongated plate 4 near the edge.

[0032] Specifically, the support rod 1 is usually made of high strength, and two long rods 11 are located on the left and right sides of the bottom end of the support rod 1. A locking hole 16 is opened at the middle of the top of the connecting column 20. The locking hole 16 is usually circular, and the locking post 19 matches it. The locking post 19 is fixedly connected at the left end of the elongated plate 18. The locking post 19 is cylindrical and its inner diameter matches the locking hole 16 at the middle of the top of the connecting column 20. Then the locking post 19 is inserted into the locking hole 16. Since the outer wall of the locking post 19 engages with the inner side of the locking hole 16, the locking post 19 can be stably fixed in the locking hole 16, realizing the connection between the left and right sides.

[0033] Please see the appendix Figure 3 - Appendix Figure 5 The stabilizing mechanism 2 includes a threaded rod 201, the top of which is fixedly connected to the bottom of the long rod 11.

A rotating shaft 208 is rotatably connected to the other end of the inclined plate 207. A support plate 203 is fixedly connected to the bottom of the rotating shaft 208. A threaded ring 212 is threadedly connected to the upper middle part of the outer wall of the threaded rod 201. A threaded ring 211 is threadedly connected to the lower middle part of the outer wall of the threaded rod 201. A T-slider 204 is fixedly connected to the middle of the outer wall of the threaded ring 212. A T-slider 209 is fixedly connected to the middle of the outer wall of the threaded ring 211. An anti-slip pad 202 is fixedly connected to the bottom of the support plate 203.

The shape of the T-slide 205 is adapted to the T-slots 210, and it can slide smoothly along the T-slots 210. One end of the T-slide 205 is embedded in the T-slots 210, and the other end is rotatably connected to the first rotating shaft 206, so that the T-slide 205 and the first rotating shaft 206 can rotate relative to each other. One end of the inclined plate 207 is connected to the T-slide 205 through the first rotating shaft 206, so that the inclined plate 207 can rotate around the first rotating shaft 206. In the upper and lower middle parts of the outer wall of the threaded rod 201, there are threaded rings 212 and 211. The inner walls of the threaded rings 212 and 211 are machined with internal threads that match the threads on the outer wall of the threaded rod 201, so that they can move up and down on the threaded rod 201.

[0035] Please see the appendix Figure 1 - Appendix Figure 3A warning light 3 is fixedly connected to the top of the support rod 1. Fluorescent stickers 5 are fixedly connected to the top of the elongated plate 4. Fluorescent stickers 3 13 are fixedly connected to the front side of the C-shaped plate 14.

A protective strip 21 is fixedly connected to the bottom of the lower elongated plate 4. A limit plate 17 is fixedly connected to the top of the locking post 19.

[0036] Specifically, the fluorescent patch 5 is a fluorescent patch that can emit light at night or in low light conditions. The top of the two reinforcing strips 6 are bolted together with a horizontal plate 15. The bottom of the elongated plate 4 on the lower side is fixedly connected with a protective strip 21. A limit plate 17 is fixedly connected to the top of the locking post 19.

[0037] Working principle: When assembling the guardrail, first fix the support rod 1 with the long rod 11 and connect them through the long plate 4. Then, fix the connecting plate 2 9 with the locking post 19 on the long plate 2 18. At the same time, connect the connecting plate 1 8 with the connecting post 20. Then, lock the locking post 19 along the inside of the locking hole 16 on the connecting post 20 to assemble and splice the guardrail. Finally, turn the threaded knob 12 to limit the locking post 19. Therefore, the guardrail can be effectively installed and assembled, which is convenient for operators to install and use, and improves portability.

[0038] At this time, the threaded ring 212 connected to the outer wall of the rotating threaded rod 201 moves downward, so that the T-shaped slider 205 slides downward along the inner side of the T-shaped groove 210. Through the rotation shaft 206 and the inclined plate 207, the support plate 203 connected to the rotation shaft 208 is expanded outward, thereby increasing the support area of ​​the guardrail. Therefore, the stability of the guardrail can be effectively enhanced, avoiding tilting during use and making it easier for operators to use.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
