Description

Technical Field

[0001] This utility model relates to the field of road construction technology, specifically a warning device for municipal road construction. Background Technology

[0002] Municipal road construction refers to the construction, maintenance, and upkeep of commonly used materials in municipal road engineering, including quality inspection, roadbed engineering, road base construction, asphalt pavement, cement concrete pavement, curbs and kerbs, sidewalks (plazas), drainage wells and stormwater branch pipes, and urban road lighting. When carrying out road construction, it is essential to implement appropriate protective measures. The most common measure is the municipal road construction warning device. However, existing municipal road construction warning devices only serve a single purpose and have limited effectiveness.

[0003] Currently, the common municipal road construction warning signs on the market are usually deployed in front of the construction site, which cannot provide an effective construction range for passing vehicles and pedestrians. Vehicles and pedestrians are likely to mistakenly enter the core construction area and enter dangerous sections of the road, leading to subsequent safety risks.

[0004] Therefore, a warning device for municipal road construction is proposed to address the above-mentioned problems. Utility Model Content

[0009] Preferably, warning lights are fixedly installed on both sides of the front of the warning board, a support base is fixedly installed on the top of the back of the warning board, and a photovoltaic panel is fixedly installed on the top of the support base.

[0010] Preferably, a steering seat is fixedly installed in the middle of the back of the warning board, a support arm is rotatably installed inside one side of the steering seat, and a support foot is rotatably installed in the middle of the end of the support arm.

[0011] Preferably, a handle is fixedly installed at the top of the positioning cylinder and outside the connecting seat.

[0012] The beneficial effects of this utility model are: 1. This utility model achieves the function of clearly defining the construction range through the structural design of the connecting seat, positioning cylinder, positioning roller, extension belt, reflective belt and positioning rod, and through the cooperation between the structures. Thus, the width of the construction area can be covered by extending to different angles on both sides to form a clear lateral construction boundary. At the same time, the extension and contraction increase portability and solve the problem of unclear construction range boundaries.

[0013] 2.

[0018] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail. This application discloses a municipal road construction warning device, including a warning board 1. Connecting seats 2 are fixedly installed on both sides of the back of the warning board 1. A positioning cylinder 3 is rotatably installed inside the connecting seat 2. A positioning roller 4 is rotatably installed inside the positioning cylinder 3. An extension belt 5 is fixedly installed on the surface of the positioning roller 4. The extension belt 5 passes through the positioning cylinder 3. A reflective strip 6 is fixedly installed on the surface of the extension belt 5. A positioning rod 7 is movably installed at the end of the extension belt 5.

[0019] Reference Figure 1 , Figure 2 , Figure 3 Through the structural design of connecting seat 2, positioning cylinder 3, positioning roller 4, extension belt 5, reflective belt 6, and positioning rod 7, and through the cooperation between the structures, the function of clearly defining the construction scope is realized. Thus, by extending to different angles on both sides to cover the width of the construction area, a clear lateral construction boundary is formed, while the extension and contraction increase portability.

[0020] The bottom of the positioning rod 7 is fixedly connected to the first leg 8 via a flange. The bottom of the first leg 8 is fixedly installed with the first extension plate 9. The top side of the first extension plate 9 is fixedly installed with the first bolt 10. The surface of the first bolt 10 is fitted with the first counterweight 11.

[0021] Reference Figure 1 and Figure 3 Through the cooperation of the first leg 8, the first extension plate 9, the first bolt 10, and the first counterweight 11, the function of increasing stability is achieved, thereby increasing the weight at the bottom of the end extension belt 5 and improving the stability of the positioning rod 7 under wind or slight impact.

[0022] The warning plate 1 is fixedly installed with a second support leg 12 at the bottom, and a second extension plate 13 is fixedly installed at the bottom of the second support leg 12. The second bolts 14 are fixedly installed on both sides of the top of the second extension plate 13, and a second counterweight 15 is sleeved on the surface of the second bolts 14.

[0023] Reference Figure 1 and Figure 4 The second leg 12, the second extension plate 13, the second bolt 14, and the second counterweight 15 work together to provide support for the warning plate 1, while ensuring the stability of the support plate and thus ensuring the warning effect.

[0024] Warning lights 16 are fixedly installed on both sides of the front of the warning board 1, and a support base 17 is fixedly installed on the top of the back of the warning board 1. A photovoltaic panel 18 is fixedly installed on the top of the support base 17.

[0025] Reference Figure 1 , Figure 2 , Figure 4 The warning light 16 can enhance the nighttime warning effect by flashing light, thereby improving the visibility of the warning board 1. The photovoltaic panel 18 can absorb solar energy and convert it into electrical energy to power the warning light 16, thus achieving green energy saving and long-lasting operation.

[0026] A steering seat 19 is fixedly installed in the middle of the back of the warning plate 1. A support arm 20 is rotatably installed inside one side of the steering seat 19. A support foot 21 is rotatably installed in the middle of the end of the support arm 20.

[0027] Reference Figure 1 and Figure 4 The steering seat 19 provides a pivot point for the support arm 20, making it easy to adjust the angle of the support arm 20 and thus control the tilt angle of the warning board 1. The cooperation between the support arm 20 and the support foot 21 achieves the function of supporting, thereby providing back support for the warning board 1 and further increasing the stability of the warning board 1.

[0028] A handle 22 is fixedly installed at the top of the positioning cylinder 3 and outside the connecting seat 2.

[0029] Reference Figure 1 and Figure 3 The operator can easily rotate the positioning cylinder 3 via the handle 22, thereby achieving the purpose of quickly releasing and winding the extension belt 5.

[0030] Working principle: When using this device, basic warning information is conveyed through the front slogan and the warning lights 16 on both sides of the warning board 1. Solar energy is converted into electrical energy by the photovoltaic panel 18 to continuously power the warning lights 16. Rotating the handle 22 at the top of the positioning cylinder 3 can drive the positioning roller 4 to rotate, realizing the unfolding or retraction of the extension belt 5. After the extension belt 5 is unfolded, it is fixed to the ground by the positioning rod 7 and the first support leg 8 to form a horizontal warning boundary. The width of the construction area is clearly defined by the surface reflective strip 6. The vertical stability of the main body of the warning board 1 is ensured by the second support leg 12, the second extension plate 13 and the second counterweight 15. The tilt angle of the warning board 1 can be adjusted according to the site environment by the rotation of the support arm 20 inside the steering seat 19 to prevent the warning board 1 from tipping over. The first support leg 8, the first extension plate 9 and the first counterweight 11 ensure that the extension belt 5 is firmly positioned after tensioning.
