plates 6 are respectively arranged in parallel with the driving plate 5, at the moment, the guardrail 3 drives the guardrail top cover 2 to slowly rise, the threaded rod 403 continues to rotate, and the movable block 404 continues to drive the driving rod 405 to move rightwards, when the driving rod 405 moves to the inner wall of the third driving groove 408, the guardrail top cover 2 reaches the highest point at the moment, the driving rod 405 drives the driving plate 5 to move upwards through the third driving groove 408, and the driving plate 5 drives the movable plate 6 to move upwards, when the driving rod 405 is located at the rightmost point of the third driving groove 408, the guardrail top cover 2 is at the highest point, meanwhile, the two movable plates 6 rotate relatively under the action of the arc arrangement of the top of the inner wall of the steel groove 1 and are flatly laid at the top of the steel groove 1, the two movable plates 6 seal the top of the steel groove 1, so that the condition that the device cannot run due to the falling of stones in the steel groove 1 in use is avoided, when the positive and negative motor 417 rotates reversely, the guardrail top cover 2 falls, the two movable plates 6 slowly return to the inside of the steel tank 1 until the guardrail top cover 2 is positioned inside the steel tank 1, the two movable plates 6 are paved at the top of the steel tank 1 again at the moment, namely, when the guardrail top cover 2 is used or not used, stones can be prevented from entering the inside of the steel tank 1, the gap 17 is arranged to allow a vacancy to be reserved for the guardrail 3, the situation that the two movable plates 6 cannot be closed due to the existence of the guardrail 3 is prevented, when the guardrail 3, the guardrail top cover 2 and the connecting frame 14 are impacted, the guardrail top cover 2 is enabled to drive the fixing seat 411 to move left and right through the guardrail 3 in cooperation with the worm 402 and the fixing shaft 413, the fixing seat 411 is further enabled to extrude the telescopic rod 414 and the damping spring 415, the telescopic rod 414 and the damping spring 415 play a role in buffering for the left and right movement of the fixing seat 411, and the guardrail top cover 2 and the connecting frame 14 have a certain buffering function when the guardrail 3, the guardrail top cover 2 and the connecting frame 14 are impacted, therefore, the service life of the equipment is prolonged, meanwhile, through the arrangement of the universal joint 416, when the fixed seat 411 drives the worm wheel 401 to move left and right, the transmission relationship between the worm wheel 401 and the threaded rod 403 can still be kept, when the guardrail 3, the guardrail top cover 2 and the connecting frames 14 are greatly impacted, the first rubber connecting belt 12 and the second rubber connecting belt 15 can be directly broken due to huge impact force at the moment, the condition that the guardrail 3, the guardrail top cover 2 and the connecting frames 14 are impacted at a certain position can be avoided, and the damage can be effectively prevented, through the arrangement of a plurality of steel grooves 1, the first rubber connecting belt 12 between two guardrail top covers 2 and the second rubber connecting belt 15 between two connecting frames 14, the device can be adjusted according to road conditions, the device is not always vertically arranged and can be slightly bent according to a lane, and only the assembly of each component needs to be completed inside the steel groove 1 at present when the device is installed, then dig the recess in lane traffic marking department, and put into steel bay 1 can, because the device sets up in morning and evening tides lane traffic marking department, general morning and evening tides lane traffic marking is the solid line mostly, this condition that the wheel pressed from the device when just making the device not use is less, even the wheel pressed from the device, because limiting plate 7 can be to guardrail top cap 2 in the effect of the play support of steel bay 1, and fly leaf 6 is located guardrail top cap 2 top, can play the supporting role to the wheel, make the device not fragile, through setting up mount 409 and spacing gyro wheel 410, make when the movable block 404 removes reducible and limiting plate 7 and steel bay 1 inner wall between the friction.
