[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] A highway maintenance safety separation device, such as Figure 1 - Figure 6As shown, the system includes two pillars 1. A base 11 is fixedly installed at the bottom of each pillar 1. In use, the base 11 is placed flat at the end of the road maintenance area. A first fence panel 2 is fixedly installed between the two pillars 1. The first fence panel 2 is comb-shaped. A second fence panel 22, also comb-shaped, is slidably installed on the first fence panel 2. The second fence panel 22 is offset from the comb-shaped panels on the first fence panel 2. After sliding down into position, the second fence panel 22 can be assembled with the first fence panel 2 to form a complete structure. The fence is formed into a rectangular panel. Reflective stickers are affixed to both fence panel 1 (2) and fence panel 2 (22). A horizontal bar 21 is fixedly installed on the top of fence panel 2 (22), and the horizontal bar 21 can fit against the top of fence panel 1 (2). Threaded sleeves 24 are fixedly installed on both sides of the top of fence panel 1 (2). The inner circular wall of the threaded sleeve 24 has internal threads. A through hole is formed on fence panel 1 (2) corresponding to the position of the threaded sleeve 24. The hollow area inside the through hole extends through the bottom of fence panel 1 (2). The top sides of fence panel 1 (2)... A threaded shaft 23 is rotatably installed at the position of the threaded sleeve 24. The outer circular wall of the threaded shaft 23 has an external thread. The threaded shaft 23 is threadedly connected to the corresponding threaded sleeve 24. Two grooves are symmetrically opened on both sides of the outer wall of the column 1. Stabilizing components are set inside the grooves. The stabilizing components are used to improve the overall stability of the column 1 when it is placed. Positioning grooves 12 are opened on both sides of the top of the pier 11 at the positions corresponding to the grooves on the column 1. The positioning grooves 12 are used to cooperate with the stabilizing components. By setting up fence plate one 2 and fence plate two 22, during highway maintenance, fence plate one 2 and fence plate two 22 are spliced ​​together to form a rectangular partition plate, which intercepts and separates from the end of the maintenance area to achieve a separation and warning effect. At the same time, the height of fence plate two 22 is adjustable and can be adjusted according to the actual situation on site. Stabilizing components are also set up to provide auxiliary support from both sides of the column 1 when it is placed on the ground, thereby improving the stability of the column 1 when it is placed.

[0018] Furthermore, the stabilizing component includes a rotating arm 3, which is movably mounted inside a groove on the column 1. The rotating arm 3 can slide downwards inside the groove. When the rotating arm 3 slides to its lowest position, it can rotate and unfold away from the column 1. The inner wall of the groove has symmetrically formed sliding grooves on both sides. A connecting shaft 34 is symmetrically fixedly mounted on the rotating arm 3, and the connecting shaft 34 is movably mounted inside the sliding groove. The connecting shaft 34 has threaded holes. Bolts are threaded onto both sides of the outer wall of the column 1. When the winding wheel 33 slides to its lowest position, the bolts can be threaded into the connecting shaft 34 to stabilize the rotating arm 3. 3. A second rotating arm 31 is rotatably mounted on the first rotating arm 3. The second rotating arm 31 is rotatably connected to the first rotating arm 3 via a rotating shaft. After the first rotating arm 3 rotates to a horizontal position, the second rotating arm 31 can be rotated out and its angle adjusted to contact the ground. When the second rotating arm 31 is stored inside the groove, one end of the second rotating arm 31 is inserted into the positioning groove 12. A conical insert block 32 is fixedly installed at the free end of the second rotating arm 31. The conical insert block 32 has a conical structure. Two winding wheels 33 are symmetrically rotatably mounted inside the first rotating arm 3. The winding wheels 33 are rotatably mounted inside the first rotating arm 3 via a rotating shaft. A torsion spring 342 is fitted onto the shaft used to connect the take-up reel 33. A pull rope 341 is provided on the take-up reel 33, and the pull rope 341 is wound around the take-up reel 33. One end of the pull rope 341 is fixedly connected to the take-up reel 33. Two L-shaped mounting slots are symmetrically opened on both sides of the interior of the rotating arm 3. A fixed pulley 343 is rotatably installed inside the mounting slot. The fixed pulley 343 is located at the corner of the L-shaped mounting slot. The pull rope 341 extends all the way into the interior of the mounting slot, passes around the fixed pulley 343, and extends downward through the interior of the mounting slot. One end of the pull rope 341 extending downward is fixed. The limit block 344 is installed. When in use, the limit block 344 can be tied to an external counterweight, such as a brick. With the stabilizing component, during highway maintenance, the column 1 is placed at the end of the highway maintenance area. By unfolding the first rotating arm 3 and the second rotating arm 31, the cone-shaped insert 32 abuts against the ground to support the column 1 from both sides, improving the stability of the column 1. At the same time, by pulling the limit block 344 and tying it with a counterweight (such as a brick), the column 1 is stabilized from the middle position between the support points on both sides, further improving the stability of the column 1 when it is placed.

[0019] The working principle of this utility model is as follows: During highway maintenance, the entire device is moved to the end of the maintenance area, the column 1 is placed on the ground, and the fence panel 1 2 and the fence panel 22 can be separated and warned from the end of the maintenance area. If only a warning is needed, simply place post 1 in the maintenance area. The height of fence panel 22 does not need to be adjusted. If it is necessary to intercept pedestrians, the threaded shaft 23 can be rotated. When the threaded shaft 23 rotates, it is threadedly connected to the threaded sleeve 24. The crossbar 21 and fence panel 22 can be moved upward. At this time, the interception height increases, which can intercept pedestrians. In windy weather, the rotating arm 31 can be slid upwards first, and one end of the rotating arm 31 will disengage from the positioning groove 12. Then, the rotating arm 3 and the rotating arm 31 can be rotated to the side away from the column 1 to unfold. The rotating arm 3 can be slid downwards until it is in contact with the top of the pier 11. The rotating bolt is threaded into the threaded hole on the connecting shaft 34, and the rotating arm 3 is fixed. The rotating arm 31 can be rotated until the cone-shaped block 32 contacts the ground. The limiting block 344 can be pulled downwards, and the pulling rope 341 can be extended. The counterweight (such as a brick) can be tied to the free end of the pulling rope 341. The counterweight can be added downwards from the middle position between the column 1 and the cone-shaped block 32, making the column 1 more stable.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
