[0025] The display panel 4 is a liquid crystal display screen, and an existing remote control can be used to control the display panel 4 to change the display color, thereby playing a role in construction early warning and the like. With the laying of the steel rail, the driving motor 11 can be remotely driven to rotate, so that the device can follow the steel rail and move along the steel rail without frequent disassembly and installation, thereby following the steel rail to facilitate timely early warning and command, such as displaying yellow to speed up the construction period, displaying red to pay attention to avoiding the crane, displaying green to pay attention to rest in hot weather, or displaying the construction notice and the like.

[0027]

[0028] ​​​The upper side of the supporting rod 54 is rotationally connected with a rolling column 56, the both sides of the load bearing seat 1 are respectively fixedly connected with an inclined rod 57, the lower end of the inclined rod 57 is fixedly connected with an isosceles trapezoidal block 58, and the rolling column 56 rolls on the waist line 581 of the isosceles trapezoidal block 58;

[0029] The yield force of the second torsion spring is smaller than that of the first torsion spring, the first torsion spring makes the supporting rod 54 rotate upward and the rolling column 56 roll on the waist line of the isosceles trapezoidal block 58, and the supporting rod 54 rotates outward around the hinge plate 52; the upward rotating force of the first torsion spring is far greater than the force restraining the second torsion spring, so that the hinge plate 52 rotates upward and the supporting rod 54 presses against the isosceles trapezoidal block 58, the supporting rod 54 gives way outward, and the second torsion spring is pressed.

[0030] With the laying of the steel rail, since the laying end of the steel rail has not been laid with the subsequent steel rail, only the foundation arrangement or ballast filling process is carried out, at this time, timely command instruction needs to be given, the rolling condition is observed through the camera, and the remote control driving motor 11 is used to make the present application roll, so that the present application does not derail and fall due to excessive remote control.
