[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] like Figure 1 , Figure 2 and Figure 4As shown, the utility model provides a technical solution: a highway maintenance worker work warning device, including a base 1, a plurality of universal wheels 11 are installed at the bottom end of the base 1, a warning plate 3 is arranged on the upper side of the base 1 to facilitate the movement of the device, and a warning light 31 is installed at the top of the warning plate 3, a lifting assembly 2 for lifting the warning plate 3 is installed between the base 1 and the warning plate 3, the lifting assembly 2 includes a motor 21 and a support rod 22, the motor 21 is installed inside the base 1, the support rod 22 is installed at the top of the base 1, and the top of the support rod 22 is provided with a The movable groove 23, the output end of the motor 21 is connected to a screw rod 24, and the screw rod 24 is rotatably installed in the movable groove 23, the surface of the screw rod 24 is threadedly sleeved with a movable sleeve rod 25, and the top of the movable sleeve rod 25 is connected to the bottom end of the warning plate 3. This structure allows the warning plate 3 to be raised and lowered, so that the space occupied by the device can be reduced when not in use. Two groups of indicator plates 4 are set at one end of the warning plate 3, and support plates 32 are connected on both sides of one end of the warning plate 3 close to the indicator plate 4, which can increase the supporting force of the indicator plate 4 when it is in a horizontal state, thereby making the indicator plate 4 more stable.

[0023] As an implementation method in this embodiment, Figure 3 and Figure 5 As shown, an adjustment component for adjusting the direction of the indicator plate 4 is installed at one end of the warning plate 3 close to the indicator plate 4, the adjustment component includes a mounting component 5 for rotating the indicator plate 4 and a limiting component 6 for limiting the position of the indicator plate 4, the two groups of indicator plates 4 are fixed to the warning plate 3 through the mounting component 5, the mounting component 5 includes a connecting plate 1 51 and a limiting block 55, the connecting plate 1 51 is connected to the warning plate 3, one end of the connecting plate 1 51 is connected to a connecting shaft 52, and one end of the connecting shaft 52 passes through the two groups of indicator plates 4 and connects to the connecting plate 2 53, the connecting plate 2 53 and the end of the connecting plate 1 51 close to the indicator plate 4 are both provided with an arc groove 54, the limiting block 55 is connected to the indicator plate 4, and the limiting block 55 slides in the arc groove 54, this structure allows the indicator plate 4 to be rotated 180 degrees, so that the indicator plate 4 can be adjusted to a horizontal position more quickly.

[0024] As an implementation method in this embodiment, Figure 4 and Figure 5As shown, the limit assembly 6 includes a connecting rod 61 and a connecting block 65. The connecting rod 61 is fixedly connected to the connecting plate 2 53, and the connecting block 65 is fixedly connected to the connecting plate 1 51. A slide groove 62 and a limit groove 66 are respectively provided at the ends of the connecting rod 61 and the connecting block 65 that are close to each other. A spring 63 is installed on the inner side of the slide groove 62, and a limit rod 64 is slidably installed at the opening of the slide groove 62. The surfaces of the two groups of indicator plates 4 are penetrated by limit holes 41, and the limit rod 64 passes through the limit hole 41 and is inserted into the limit groove 66. The inner wall of the limit rod 64 is connected to a pull rod 67. This structure makes it possible to limit the indicator plate 4, and the operation of opening the limit is also more convenient and easy. One end of the pull rod 67 passes through the spring 63 and extends to the outside of the connecting rod 61. A handle 68 is installed on the outer end of the pull rod 67 to make it more convenient to pull the pull rod 67 through the handle 68.

[0025] Working principle: If you need to use the device to warn workers when they are working, you only need to hold the handle 68 and pull the pull rod 67. The pull rod 67 drives the limit rod 64 to slide into the slide groove 62 until the limit rod 64 is pulled out of the limit groove 66 and completely moves from the limit hole 41 to the slide groove 62 to compress the spring 63, so that the indicator plate 4 can be operated to rotate. At this time, the indicator plate 4 will drive the limit block 55 to slide in the arc groove 54, and then the indicator plate 4 can be rotated to the horizontal direction. The indicator plate 4 can adjust the left and right indication directions as needed, which is more convenient. In addition, when the indicator plate 4 is in a horizontal state, it is placed on the support plate 32. The support plate 32 can support the indicator plate 4, which is more stable, so as to better remind passing vehicles of the construction ahead and indicate the vehicles to avoid the lane;

[0026] In addition, if the device needs to be folded up, it is only necessary to start the motor 21 to drive the screw rod 24 to rotate, and through the rotation of the thread, drive the movable sleeve rod 25 to slide in the movable groove 23 until the movable sleeve rod 25 is retracted into the movable groove 23. In this way, the device saves more space when placed, greatly increasing the practicality of the device.

[0027] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
