The driving member 21 is a rotating hand wheel.
[0019] The use method of the present application: when the early warning device is needed to be set in the highway construction process to prompt the passing vehicles, the staff pushes the push rod 101 to move the early warning device to the use site, then adjusts the early warning direction, and then drives the driving member 21. The driving member 21 rotates to drive the threaded rod 22 to rotate, the threaded rod 22 rotates to drive the first sliding block 23 to move right, the first sliding block 23 moves right to drive the mounting plate 27 to move right, the mounting plate 27 moves right to drive the L-shaped base 28 to move right, and the L-shaped base 28 moves right to drive the left end of the early warning plate 2 to move right. And the vertical plate 24 away from the driving member 21 is provided with the first end of the first rotating column 29 rotatingly connected on the front and back sides, the second end of the first rotating column 29 is provided with the vertical rod of the first L-shaped rod 211 connected with the horizontal rod, and the middle part of the front and back sides of the early warning plate 2 is provided with the first end of the second rotating column 210 rotatingly connected, and the second end of the second rotating column 210 is connected with the vertical rod end of the first L-shaped rod 211 perpendicularly. So that the left end of the early warning plate 2 moves right at the same time, the vertical rod of the first L-shaped rod 211 connected with the horizontal rod rotates clockwise around the first rotating column 29, thereby promoting the left end of the early warning plate 2 to rotate counterclockwise around the L-shaped base 28 by 90 degrees, so that the early warning plate 2 counterclockwise rotates while moving right to convert the early warning plate 2 from the folding state to the working state, and the early warning sign 212 installed on the early warning plate 2 prompts the passing vehicles, ensures the safe construction and guarantees the safe driving of the passing vehicles, and the volume is small in the folding state, which is convenient for the staff to carry; At the same time, the early warning plate 2 counterclockwise rotates by 90 degrees while moving right to convert the early warning plate 2 from the folding state to the working state to drive the push rod 101 to rotate counterclockwise by 90 degrees synchronously, so that the push rod 101 rotates from perpendicular to the horizontal plane to parallel to the horizontal plane, the push rod 101 is retracted, the push rod 101 is prevented from interfering with the line of sight of the passing vehicles, and the early warning plate 2 is better displayed. Meanwhile, since the warning plate 2 is equipped with mounting rods 41, the inner side of the mounting rods 41 is provided with a first sliding groove, and a fourth rotating column 42 is slidably provided in the first sliding groove. One end of each of the two fourth rotating columns 42 slides through the first sliding groove and is connected to the same cleaning roller 4. The vertical end of the second L-shaped rod 43 is rotatably mounted on one of the fourth rotating columns 42 that passes through the first sliding groove. The horizontal end of the second L-shaped rod 43 is hinged to the top of the upright plate 24 near the drive member 21. When the warning plate 2 moves to the right and rotates counterclockwise, it causes the cleaning roller 4 to move from the right end to the left end of the warning plate 2 for cleaning, thereby improving the cleanliness of the warning mark 212 on the warning plate 2 and enhancing the warning effect. Simultaneously, the connection between the vertical and horizontal bars of the first L-shaped rod 211 rotates clockwise around the first rotating column 29, causing the end of the horizontal bar of the first L-shaped rod 211 to rotate clockwise around the first rotating column 29. The rotation of the end of the horizontal bar of the first L-shaped rod 211 around the first rotating column 29 causes the third rotating column 31 to rotate clockwise. The clockwise rotation of the third rotating column 31 causes the moving rod 32 to move upward. The upward movement of the moving rod 32 causes the rectangular rod 33 and the connecting rod 34 to move upward. The upward movement of the connecting rod 34 causes the moving wheel 3 to move upward. The upward movement of the moving wheel 3 then retracts the moving wheel 3, so that the bottom of the box 1 is in direct contact with the ground, which increases the contact area between the device and the ground, facilitates the stability of the entire device, and improves the practicality of the device. Simultaneously, the upward movement of the rectangular rod 33 causes the first end of the first rotating rod 51 to move upward, which in turn causes the second end of the first rotating rod 51 to move outward. The outward movement of the second end of the first rotating rod 51 causes the third slider 52 to move outward, which in turn causes the push rod 53 to move outward. The outward movement of the push rod 53 causes the stabilizing block 5 to move outward, and the stabilizing block 5 moves outward and contacts the ground. This increases the overall contact range between the device and the ground, preventing the device from easily moving or tipping over when touched by staff or in windy weather, thus improving the warning effect. This increases the stability of the device and enables it to provide a good warning effect for passing vehicles. Once the construction warning ends, staff can reverse the operation to retract the device to the extended / retracted state.
[0020] The application realizes that the early warning board is converted from the storage state to the working state through counterclockwise rotation while moving to the right, and the passing vehicles are prompted through the early warning signs installed on the early warning board, so as to ensure the safe construction and the safe driving of the passing vehicles, and the volume is small in the storage state, so as to facilitate the carrying of the staff; meanwhile, the push rod is rotated from perpendicular to the horizontal plane to parallel to the horizontal plane, the push rod is retracted, the line of sight of the passing vehicles is prevented from being interfered by the push rod, and the early warning board is better displayed; the early warning board is converted from the storage state to the working state through counterclockwise rotation while moving to the right through the setting of the cleaning mechanism; meanwhile, the push rod is rotated from perpendicular to the horizontal plane to parallel to the horizontal plane; meanwhile, the cleaning roller moves from the right end to the left end of the early warning board for cleaning, the cleanliness of the early warning signs on the early warning board is improved, and the early warning effect is improved; the early warning board is converted from the storage state to the working state through counterclockwise rotation while moving to the right through the setting of the moving mechanism; meanwhile, the push rod is rotated from perpendicular to the horizontal plane to parallel to the horizontal plane; meanwhile, the cleaning roller moves from the right end to the left end of the early warning board for cleaning; meanwhile, the moving wheel moves upward and is retracted, so that the bottom of the box body is in direct contact with the ground, the contact area of the device with the ground is improved, the device is facilitated to be stabilized as a whole, and the practicability of the device is improved; the early warning board is converted from the storage state to the working state through counterclockwise rotation while moving to the right through the setting of the stabilizing mechanism; meanwhile, the push rod is rotated from perpendicular to the horizontal plane to parallel to the horizontal plane; meanwhile, the cleaning roller moves from the right end to the left end of the early warning board for cleaning; meanwhile, the moving wheel moves upward and is retracted; meanwhile, the stabilizing block moves outward and is in contact with the ground, so that the range of contact of the device with the ground as a whole is improved, the phenomenon of movement or toppling is prevented from occurring when the staff touches or blows in the wind, the early warning effect is poor, the stability of the device is improved, the device can have a good early warning effect on the passing vehicles; the application has the advantages of simple and reliable structure, good early warning effect on highway construction, convenient control, and suitability for promotion.
