[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-5 As shown, a road construction safety management device for highway maintenance includes a base 101. The top of the base 101 is fixedly connected to two symmetrical support rods 102. The top of the support rods 102 is fixedly connected to a fixed plate 301. A movable column 302 is rotatably connected between the symmetrical fixed plates 301. A warning plate 502 is provided on the movable column 302. Multiple limiting holes 405 are opened on one side of the fixed plate 301. The limiting holes 405 are evenly distributed around the circumference of the fixed plate 301.

[0026] The movable column 302 is provided with a limiting mechanism on one side close to the limiting hole 405. The limiting mechanism comprises a fixed plate 401 fixedly installed on the movable column 302. The fixed plate 401 is slidingly connected with a sliding rod 402. The sliding rod 402 is fixedly connected with a limiting plate 403 on the side away from the limiting hole 405. The limiting plate 403 is fixedly connected with a spring 404 on the side close to the fixed plate 401. The spring 404 is sleeved outside the sliding rod 402 and is fixedly connected with the fixed plate 401. The end of the sliding rod 402 away from the limiting plate 403 is slidingly connected with the limiting hole 405. When it is necessary to adjust the inclination angle of the warning board 502 relative to the ground, the limiting plate 403 is pulled to drive the sliding rod 402 to disengage from the limiting hole 405, the sliding rod 402 is driven to slide with the fixed plate 401 to stretch and deform the spring 404. Then the movable column 302 is rotated. When the warning board 502 is adjusted to the appropriate position, the limiting plate 403 is released, so that the spring 404 restores the deformation to drive the sliding rod 402 to be inserted into the corresponding limiting hole 405.

[0027] The warning board 502 is located on the side of the movable column 302 away from the fixed plate 401. The warning board 502 is provided with a mounting assembly between the movable column 302.

[0028] The mounting assembly comprises symmetrical fixed seats 501 fixedly connected with the movable column 302. The fixed seats 501 are fixedly connected with the warning board 502 on the side away from the fixed plate 401. The warning board 502 is mounted on the movable column 302 through the fixed seats 501.

[0029] The base 101 is slidingly connected with a lifting bottom plate 202. The lifting bottom plate 202 is fixedly connected with front and rear symmetrical universal wheels 203 on both sides. The lifting bottom plate 202 is provided with a lifting assembly between the base 101.

[0030] The lifting assembly comprises a threaded rod 201 rotatingly connected with the top wall of the base 101. The threaded rod 201 is screwedly connected with the lifting bottom plate 202. The threaded rod 201 is fixedly connected with a rotating disc 6 on the top. When it is necessary to move the base 101, the rotating disc 6 is rotated to drive the threaded rod 201 to rotate, so that the lifting bottom plate 202 slides with the base 101 and is screwedly connected with the threaded rod 201, and the universal wheels 203 are driven to move downward and abut against the ground.

[0031] The side supporting rod 102 is fixedly connected with a fixed ring 7 on the side away from the warning board 502. After the base 101 is moved to the use position, the rotating disc 6 is rotated to make the universal wheels 203 retract into the base 101, so that the base 101 abuts against the ground, the device is stably placed on the ground, and the lock chain is connected with the fixed ring 7 to further improve the stability of the device.

[0032] Working principle: when the base 101 needs to be moved, rotate the turntable 6 to drive the threaded rod 201 to rotate, make the lifting bottom plate 202 slide with the base 101 and threadedly cooperate with the threaded rod 201, drive the universal wheel 203 to move downward and abut against the ground, then move the base 101 to the use position through the universal wheel 203, rotate the turntable 6 to make the universal wheel 203 retract into the base 101, make the base 101 abut against the ground, make the device stably placed on the ground, connect the padlock with the fixed ring 7, further improve the stability of the device, then install the warning board 502 on the movable column 302 through the fixing seat 501, when the inclination angle of the warning board 502 and the ground needs to be adjusted, pull the limiting plate 403 to drive the sliding rod 402 to disengage from the limiting hole 405, drive the sliding rod 402 to slide with the fixed plate 401 to make the spring 404 stretch and deform, then rotate the movable column 302, when the warning board 502 is adjusted to the appropriate position, release the limiting plate 403, make the spring 404 restore the deformation to drive the sliding rod 402 to insert into the corresponding limiting hole 405.

[0033] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application.
