A plurality of universal wheels 2 are fixedly connected to the lower surface of the base 1. A push handle 4 is fixedly connected to the upper surface of the base 1. A moving mechanism 3 is fixedly connected to the upper surface of the base 1. The moving mechanism 3 includes a motor 31. The output end of the motor 31 is fixedly connected to a driving shaft 32. The upper end of the driving shaft 32 is fixedly connected to a driving gear 33. The outer wall of the driving gear 33 is meshed with a large gear 34. The upper and lower sides of the large gear 34 are fixedly connected through a threaded device 35. The threaded device 35 includes a threaded sleeve 351. The upper end of the inner wall of the threaded sleeve 351 is threadedly connected to an upper threaded column 352. The lower end of the inner wall of the threaded sleeve 351 is threadedly connected to a lower threaded column 354. The lower end of the outer wall of the upper threaded column 352 is fixedly connected to a retaining ring 353. The upper end of the outer wall of the lower threaded column 354 is fixedly connected to the retaining ring 353. The threads on the upper and lower inner walls of the threaded sleeve 351 are opposite. The lower end of the threaded device 35 is fixedly connected to a limiting plate 14. Four moving columns 12 are fixedly connected through the upper surface of the limiting plate 14. The outer walls of the four moving columns 12 are sleeved with first springs 11. One end of the first spring 11 is fixedly connected to the base 1. The other end of the first spring 11 is fixedly connected to the limiting plate 14. Clamping plates 13 are fixedly connected to both the upper and lower ends of the moving column 12. The outer wall of the moving column 12 is slidably connected to the base 1. The upper end of the moving mechanism 3 is fixedly connected to a rotating mechanism 5. A turning handle 6 is fixedly connected to the outer wall of the rotating mechanism 5. A rotating block 9 is fixedly connected to the upper surface of the rotating mechanism 5. A reflective warning board 7 is movably connected to the front side of the rotating block 9. A plurality of screws 8 are arranged on the front side of the reflective warning board 7. The outer walls of the plurality of screws 8 are threadedly connected to the rotating block 9. A clamping mechanism 10 is arranged on the upper surface of the rotating block 9. By means of the motor 31, the driving shaft 32 can be driven to rotate, thereby driving the driving gear 33 to rotate. The driving gear 33 cooperates with the large gear 34 to drive the threaded sleeve 351 to rotate. During the rotation of the threaded sleeve 351, the upper threaded column 352 and the lower threaded column 354 will be driven to move simultaneously. The upper threaded column 352 will drive the device to rise, and the lower threaded column 354 will drive the limiting plate 14 to descend to fix the device. During the movement of the limiting plate 14, the first spring 11 will give a certain thrust to the limiting plate 14 to improve the stability of the device.

[0025] As Figures 4-5As shown in the figure, the present utility model provides a technical solution: Preferably, the rotating mechanism 5 includes a fixed seat 51. The inner wall of the fixed seat 51 is rotatably connected with a rotating seat 52. The bottom inner wall of the rotating seat 52 is fixedly connected with a fixed block 53. The front side of the fixed block 53 is fixedly connected with a guide post 54. A second spring 55 is sleeved on the outer wall of the guide post 54. One end of the second spring 55 is fixedly connected with the fixed block 53, and the other end of the second spring 55 is fixedly connected with a stop block 56. The front side of the stop block 56 is fixedly connected with a telescopic column 57. The outer wall of the guide post 54 is slidably connected with the telescopic column 57. The clamping mechanism 10 includes a crank 101. The lower side of the crank 101 is fixedly connected with a threaded rod 102. A moving plate 103 is threadedly connected to the outer wall of the threaded rod 102. Sliders 106 are fixedly connected to both the left and right sides of the moving plate 103. Two connecting blocks 105 are fixedly connected to the front side of the moving plate 103. Limit blocks 104 are fixedly connected to the opposite surfaces of the two connecting blocks 105. An installation block 108 is fixedly connected to the rear side of the reflective warning board 7. Limit grooves 109 are opened on both the left and right sides of the installation block 108. The outer wall of the limit block 104 is slidably connected with the limit groove 109. The outer wall of the slider 106 is slidably connected with the chute 107. Chutes 107 are provided on both the left and right sides of the inner wall of the rotating block 9. By pressing the telescopic column 57 and then pushing the rotating handle 6, the rotating handle 6 will drive the rotating seat 52 to rotate. When it rotates to an appropriate angle and the telescopic column 57 is released, the second spring 55 will push the stop block 56 to move outwards. The telescopic column 57 cooperates with the jack on the fixed seat 51, enabling the telescopic column 57 to fix the rotating seat 52 of the device. Finally, when installing the reflective warning board 7, first screw the screw 8 into the rotating block 9, and then rotate the crank 101. The crank 101 drives the threaded rod 102 to rotate. When the threaded rod 102 rotates, it drives the moving plate 103 to move. Since the slider 106 cooperates with the chute 107 to limit the moving plate 103, the moving plate 103 can only move up and down. During the movement, it will also drive the limit block 104 to move. The limit block 104 cooperates with the connecting block 105 to clamp and fix the installation block 108, thereby clamping and fixing the reflective warning board 7.

[0026] Next, specifically describe the working principle of the safety construction warning device for chemical engineering management.

[0027] As Figures 1-5As shown in the figure, when the motor 31 is turned on, the motor 31 can drive the drive shaft 32 to rotate, thereby driving the drive gear 33 to rotate. The drive gear 33 cooperates with the large gear 34 to drive the threaded sleeve 351 to rotate. During the rotation of the threaded sleeve 351, the upper threaded column 352 and the lower threaded column 354 will be driven to move simultaneously. The upper threaded column 352 will drive the device to rise, and the lower threaded column 354 will drive the limit plate 14 to descend to fix the device. During the movement of the limit plate 14, the first spring 11 will give a certain thrust to the limit plate 14 to improve the stability of the device. Then, press the telescopic column 57, and then push the turning handle 6. The turning handle 6 will drive the turntable 52 to rotate to an appropriate angle. Release the telescopic column 57, and the second spring 55 will push the stopper 56 to move outwards. The telescopic column 57 cooperates with the jack on the fixed seat 51 to enable the telescopic column 57 to fix the turntable 52 of the device. Finally, when installing the reflective warning plate 7, first screw the screw 8 into the rotating block 9, and then turn the crank 101. The crank 101 drives the threaded rod 102 to rotate. When the threaded rod 102 rotates, it drives the moving plate 103 to move. Since the slider 106 cooperates with the chute 107 to limit the moving plate 103, the moving plate 103 can only move up and down. During the movement, the limit block 104 will also be driven to move. The limit block 104 cooperates with the connecting block 105 to be able to clamp and fix the mounting block 108, thereby clamping and fixing the reflective warning plate 7.

However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit and idea of the present invention are within the protection scope of the present invention.
