Description

Technical Field

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

[0002] With the continuous increase in the total mileage of highways, construction and maintenance of highways are indispensable. To minimize the impact on traffic efficiency, construction areas are often simply closed off, and road barriers are used to guide passing vehicles through the normal lanes. Although there are isolation and warning signs and other facilities, due to excessive vehicle speed and driver distraction, drivers often fail to notice the warning signs in time, thus rushing into the construction area and causing loss of life and property to construction workers and drivers. An existing road construction zone safety warning device and method (Announcement No.: CN111325945A) has revealed at least the following defects in its use: The above-mentioned solution monitors the real-time operation of vehicles on the road, promptly identifies vehicles traveling in the lanes of the construction area, and determines whether there is a risk of the vehicle rushing into the construction area based on information such as the vehicle type, speed, and location monitored in real time. If so, it promptly warns the workers in the construction area, enabling them to avoid the risk in time and reducing the accident rate. However, in actual use, accident vehicles often rush into the construction site at extremely high speeds, and even if there is a warning, it may still cause great harm to the unprepared construction workers. Therefore, a road construction area safety early warning device needs to be developed. Utility Model Content

[0003] The main purpose of this utility model is to provide a safety early warning device for road construction areas, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A road construction area safety early warning device includes two bases. Two rotating anti-collision frames are rotatably connected to both sides of the two bases, and the two rotating anti-collision frames corresponding to different bases are divided into two groups. Each rotating anti-collision frame has a sliding opening on one side facing the two bases. A connecting frame is fixedly connected to the inner wall of each sliding opening. A buffer spring is fixedly connected to one side of each connecting frame. A buffer plate is fixedly connected to one end of each buffer spring extending to the outside of the rotating anti-collision frame. A buffer cable is fixedly connected between two corresponding buffer plates. A buffer net is fixedly connected between the opposite sides of the two buffer cables.

[0005] Preferably, each of the buffer cables has multiple evenly distributed warning seats fixedly connected to one side, and each warning seat has a set of reflectors fixedly connected to its outer edge.

[0006] Preferably, a rotating side frame is fixedly connected to the top of the opposite sides of the two bases, and a partition bracket is fixedly connected to the opposite sides of the two rotating side frames. The two sides of the two partition brackets are rotatably connected to the corresponding rotating anti-collision frame.

[0007] Preferably, each of the rotating anti-collision frames has a traction groove on its outer edge, and a set of evenly distributed sliding frames are slidably connected between the inner walls of each traction groove, and a positioning cable is fixedly connected between the inner walls of each set of sliding frames.

[0008] Preferably, each of the positioning cables is fixedly connected to a positioning frame on the side facing the buffer arm, and each positioning frame is fixedly connected to the corresponding side of the corresponding rotating anti-collision frame.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] Please see Figures 1-4 This utility model provides a technical solution: A road construction zone safety warning device includes two bases 103. Two rotating anti-collision frames 201 are rotatably connected to both sides of each base 103. The two rotating anti-collision frames 201 corresponding to different bases 103 are divided into two corresponding groups. Each rotating anti-collision frame 201 has a sliding opening 203 on one side facing the area between the two bases 103. A connecting frame 208 is fixedly connected to the inner wall of each sliding opening 203. A buffer spring 209 is fixedly connected to one side of each connecting frame 208. A buffer latch 210 is fixedly connected to one end of each buffer spring 209 extending to the outside of the rotating anti-collision frame 201. A buffer cable 301 is fixedly connected between two corresponding buffer latches 210. A buffer net 303 is fixedly connected between the opposite sides of the two buffer cables 301. Multiple evenly distributed warning seats are fixedly connected to one side of each buffer cable 301. A set of reflectors 302 is fixedly connected to the outer edge of each warning seat. In this embodiment, the rearview mirror 302 is generally red and can reflect red light to warn the driver. In this embodiment, the base 103 has a very high density, giving the device a large self-weight, which can effectively tow the accident vehicle, while the elastic buffer net 303 and buffer spring 209 can protect the accident vehicle and prevent it from deforming due to rigid collision.

[0018] Two rotating side frames 102 are fixedly connected to the top of opposite sides of the two bases 103. A partition bracket 101 is fixedly connected to the opposite sides of the two rotating side frames 102. The two sides of the partition brackets 101 are rotatably connected to the corresponding rotating anti-collision frames 201. Each rotating anti-collision frame 201 has a traction groove on its outer edge. A set of evenly distributed sliding frames 207 are slidably connected between the inner walls of each traction groove. A positioning cable 206 is fixedly connected between the inner walls of each set of sliding frames 207. A positioning frame 202 is fixedly connected to the side of each positioning cable 206 facing the buffer arm 210. Each positioning frame 202 is fixedly connected to the corresponding side of the corresponding rotating anti-collision frame 201. A set of positioning springs 204 is fixedly connected to the side of each positioning cable 206 facing away from the buffer arm 210. A positioning buckle 205 is fixedly connected to the side of each positioning spring 204 facing away from the positioning cable 206. Each rotating side frame 102 has multiple rotating seats fixedly connected to one side. Each rotating seat corresponds to a positioning buckle 205, and each rotating seat is rotatably connected to the corresponding positioning buckle 205. In this embodiment, a vehicle impact causes the rotating anti-collision frame 201 to rotate, pulling up the positioning spring 204. When the external force disappears, the positioning spring 204 retracts, allowing the rotating anti-collision frame 201 and the buffer net 303 to return to their original positions. Both the positioning spring 204 and the buffer spring 209 have large dimensions and can withstand large tensile forces.

[0019] It should be noted that this utility model, as a safety early warning device for road construction areas, is used to place the device stably on the ground by setting up a base 103 with a relatively high density, thereby enclosing the construction site. The elastic buffer net 303 is used to block oncoming accident vehicles. In conjunction with the rotating side frame 102 and the buffer spring 209, the blocked accident vehicles are buffered and decelerated, reducing their speed and giving construction workers some reaction time, thus reducing accidental injuries and deaths among construction workers.
