Description

Technical Field

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

[0002] Road engineering refers to the whole process of planning, design, construction, maintenance and management of roads and the engineering entities involved. Like any other type of civil engineering, road engineering has obvious technical, economic and management characteristics. Roads are divided into the following categories according to their service scope and their position and role in the national road network: ① National Highways (national highways), including expressways and main trunk lines; ② Provincial Highways (regional highways); ③ County and township roads (local highways); ④ Urban roads. The first three are collectively referred to as highways, which can be divided into five technical grades according to the average annual daytime and nighttime automobile traffic volume, usage tasks and nature. Different grades of highways are reflected by different technical indicators.

[0003] During road construction, it is often necessary to place and install early warning devices on the front and rear sections of the road to ensure that passing vehicles can obtain the information of "road construction ahead" in advance. The current early warning devices are mostly large in size and require multiple people to carry them together when in use, which is inconvenient to move. They take up a large space when idle and are inconvenient to use. In addition, due to their large size, they are subject to greater wind pressure in windy weather, making the early warning devices less stable and prone to rollover, affecting the warning effect.

Obviously, the specific implementation mode described is only a part of the implementation mode of the utility model, rather than all styles.

[0023] Example:

[0024] The following is combined with Figure 1-2 The utility model is described in further detail.

[0025] See also Figure 1-2 The utility model provides a technical solution: a road construction safety warning device, including a bottom plate 1, both sides of the top of the bottom plate 1 are fixedly connected with drive motors 4, the output shafts of the two drive motors 4 are fixedly connected with screws 5, the two screws 5 are threaded with movable blocks 6, the opposite sides of the two movable blocks 6 are fixedly connected with the same warning plate 7, and the warning plate 7 is provided with a plurality of ventilation slots 11. Through the arrangement of the bottom plate 1, the concave plate 15 and the sleeve 19, the contact area between the device and the ground and the supporting effect of the warning plate 7 are increased, and the ventilation slots 11 are used to disperse the wind force, reduce the contact area between the warning plate 7 and the wind, thereby improving the stability of the device, both sides of the top of the warning plate 7 are fixedly connected with warning lights 13, and the top of the bottom plate 1 is provided with two opening slots 14, the two opening slots 14 are provided. The same concave plate 15 is clamped in the slot 14, and two studs 16 are threaded on the concave plate 15, one end of the two studs 16 are threadedly connected to the bottom plate 1, and a slot 18 is opened on the top of the concave plate 15, and a sleeve 19 is inserted in the slot 18, and a movable rod 20 is movably inserted in the sleeve 19, and a limiting tube 24 is fixedly connected to the rear side of the warning plate 7, and one end of the movable rod 20 is inserted in the limiting tube 24, and two blocks 22 and two clamps 23 are fixedly connected to the rear side of the warning plate 7. Through the joint action of the driving motor 4, the concave plate 15, the sleeve 19, the block 22 and the clamp 23, the bottom plate 1 can be retracted to the bottom of the warning plate 7, and then the disassembled concave plate 15 and the sleeve 19 can be fixed, which reduces the size of the device, makes it convenient to carry when in use, and reduces the occupied space when idle.

[0026] Specifically, first fixing holes 3 are opened on both sides of the top of the base plate 1, second fixing holes 17 are opened on both sides of the top of the concave plate 15, the top of the base plate 1 is fixedly connected to the battery 2, a controller 8 is provided on one side of the warning plate 7, and the top of the warning plate 7 is fixedly connected to the handle 12.

[0027] By adopting the above technical solution, through the setting of the first fixing hole 3 and the second fixing hole 17, it is convenient to fix the position of the device. The controller 8 can be a conventional known device for control such as a computer. The controller 8 is electrically connected to the drive motor 4, the pressure sensor 10 and the warning light 13 through wires.

[0028] Specifically, a fixing bolt 21 is threadedly passed through the sleeve 19 , one end of the fixing bolt 21 overlaps one side of the movable rod 20 , both sides of the warning plate 7 are fixedly connected with fixing blocks 9 , and the bottoms of the two fixing blocks 9 are fixedly connected with pressure sensors 10 .

In windy weather, the wind passes through the ventilation slot 11, reducing the contact area between the warning plate 7 and the wind force and improving stability. After use, the fixing bolt 21 is rotated so that one end of the fixing bolt 21 is no longer overlapped with the movable rod 20, and one end of the movable rod 20 is moved out of the limiting tube 24 and retracted to The sleeve 19 is pulled out from the slot 18 and clamped into the clamp 23. The stud 16 is rotated to take the concave plate 15 out of the open slot 14, so that the concave plate 15 is clamped into the clamping block 22. The output shaft of the drive motor 4 drives the screw 5 to rotate, and the movable block 6 falls along the screw 5 to store the warning plate 7 between the two screws 5. When the top of the screw 5 is against the pressure sensor 10, the pressure sensor 10 is sensed and the information is fed back to the controller 8, so that the drive motor 4 stops working and the storage of the early warning device is completed. Then the handle 12 can be lifted to drive the device to move.

[0031] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
