Description

Technical Field

[0001] The utility model relates to the field of road construction safety warning, and specifically relates to a road construction safety warning device. Background Art

[0002] In road construction, sewer construction often occurs (such as opening a sewer manhole cover to drain water quickly), or excavation and hole-digging are carried out at a certain place for corresponding construction; however, for sewer drainage, it needs to be carried out continuously for a certain period of time. At this time, the sewer manhole cover is open and safety warning is required. Otherwise, there will be potential safety hazards if others are unaware; the same is true for excavation construction. The dug hole will not be filled in until the construction is completed. At this time, safety warning is required, especially at night. Otherwise, there will be potential safety hazards if others are unaware; based on the current situation, the existing method is to set up a fence and enclose it with a fence. Although this method can also provide a certain degree of safety protection, the disassembly and assembly of the fence are time-consuming, and the cost of using the fence is relatively high. The fence also lacks information display and warning related to the construction. Content of the Utility Model

The device has a simple structure. When implementing, it can be placed at the construction pit or sewer. The limit support frame composed of multiple outer ring bodies and support rods can block the sewer opening or construction pit opening, and the limit rod just vertically limits and corresponds to the inner wall of the construction pit opening. When encountering a construction pit opening with a relatively large size, the integral part formed by the outer ring body, limit rod and connecting sleeve can be horizontally pulled out along the corresponding support rod, so as to adjust the support range of the limit support frame. In this application, a warning sign is equipped. The warning sign is integrally circular or square in structure, and a light-emitting warning light and a display screen are respectively arranged on both sides. The function of the light-emitting warning light is to emit warning light, which can make people at a long distance pay attention and play a warning role, while the display screen can display the corresponding situation of this construction, so that external personnel can know relevant information such as the time of this construction.
