[0022] As Figure 1 , Figure 2 , Figure 3 and Figure 4 indicated, the intelligent obstacle warning device for road construction of the present application comprises a warning board 2, a support frame 7, a shaft rod 1, a handle rod 3 and a support rod 14, one end of the warning board 2 is fixedly connected with the shaft rod 1, the other end is fixedly connected with the handle rod 3, the support frame 7 is arranged outside the shaft rod 1, bearings are embeddedly installed on both side surfaces of the support frame 7, rotating shafts 17 are installed at both ends of the shaft rod 1, the other ends of the rotating shafts 17 are installed in the inner rings of the bearings, torsional springs 18 that automatically lift the warning board 2 are sleeved outside the rotating shafts 17, a positioning assembly is installed on one side of the support frame 7, the support rod 14 is installed between the handle rod 3 and the shaft rod 1, and an intelligent reminding device is installed on the surface of the warning board 2.

[0023] In the embodiment, the intelligent reminding device comprises a cover 5, a fixing ring 16, an alarm 15 and a proximity switch 6. The fixing ring 16 is installed on the surface of the warning board 2. The cover 5 is sleeved outside the fixing ring 16 and is threadedly connected with the fixing ring 16. A plurality of sound holes are arranged on the surface of the cover 5. The alarm 15 is arranged inside the cover 5. One end of the alarm 15 is in contact with the inner wall of the cover 5, and the other end is in contact with the warning board 2. The proximity switch 6 is installed in the sound hole. The alarm 15 is controlled by the proximity switch 6. The cover can be removed from the fixing ring after the cover is rotated. After the cover is lost, the alarm can be directly taken out, which facilitates replacement. The inside of the cover is provided with a storage battery for supplying power to the proximity switch and the alarm.

[0024] In the embodiment, one end of the torsion spring 18 is installed on the shaft 1, and the other end is installed on the support frame 7. The outside of the torsion spring 18 is sleeved with a sealing tube 8 which covers the torsion spring 18. One end of the sealing tube 8 is installed on the support frame 7, and the opening of the other end is reduced inward and in contact with the outer ring surface of the shaft 1.

[0025] In the embodiment, the positioning assembly comprises a fixed plate, a plug rod 11, a spring 12 and a pull rod 13. The fixed plate is installed on the support frame 7. The fixed plate is provided with a through hole. The shaft 1 is provided with a plug hole 10 on one side. The plug rod 11 is arranged in the through hole. One end of the plug rod 11 is fixedly connected with the pull rod 13, and the other end is in contact with the outer ring surface of the shaft 1. The spring 12 is sleeved outside the plug rod 11. One end of the spring 12 is installed on the fixed plate, and the other end is fixedly connected with the pull rod 13.

[0029] When the construction vehicle needs to pass, the shaft and the warning board can be rotated around the rotating shaft. After being rotated to half, the support rod can be directly stepped on to place the warning board on the ground. After the shaft is rotated to a certain degree, the plug rod is opposite to the plug hole. At this time, the plug rod can be automatically inserted into the plug hole through the rebound of the spring. The plug rod can position the lying flat warning board to avoid being lifted upward by itself, so that the engineering vehicle can smoothly pass above the warning board without dragging and moving the warning board.

[0030] And after the construction vehicle passes, the pull rod can be pulled out from the insertion hole by hand, and after losing the positioning of the insertion rod, the automatic shaft rod and the warning sign can be automatically lifted by the torsion of the torsion spring until the warning sign contacts the rubber layer, so that the warning sign is in a vertical state to remind other vehicles.

[0031] Wherein, when the vehicle approaches the warning sign, the proximity switch can contact the approaching vehicle and start the alarm, and the sound generated by the alarm can better remind the vehicle and also remind the staff to complete the lying operation of the warning sign.

[0032] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any change or replacement without creative labor should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be limited by the protection scope defined in the claims.
