Operation principle：When trailer is turned, the turning alarm set positioned at headstock 1 can be opened, protection device of now turning
On radar range unit can detect trailer both sides whether there is personnel or other objects in real time, when detections of radar to personnel or object are leaned on
During the danger radius that nearly trailer is turned, the alarm light prompting human pilot that can send red by quick-fried sudden strain of a muscle LED notes, simultaneously
Buzzer siren can send alarm and reminding personnel and note, the in-line laser generator 9 on turning alarm set can be on ground
A red-label light is produced, for marking danger zone, red-label light can extend to the tailstock, in-line from headstock 1
Laser generator 9 adjusts light and the angle of trailer side by head, in the in-line laser generator 9 positioned at rotation direction
Adjusted by head, it is shone all the time from headstock 1 at the tailstock, form a delta-shaped region security warning area, show trailer
Lubrication groove during turning is poor, when trailer straight line is moved forward, in-line laser generator 9 can by electric platform produce one with
The parallel light in trailer side, light has certain distance apart from trailer side, reminds personnel to keep the safe distance with trailer.
When trailer is turned, turning protector can also be opened therewith, and now the protective plate 402 of the side of trailer plate 2 can pass through electric expansion
Bar 401 is put down, and protective plate 402 can will block the gap of the side of trailer plate 2 and bottom surface, and wheel face is blocked, and prevent personnel
Underbody is involved in, the side of trailer plate 2 is parallel to be provided with portable plate 403 movable up and down, it is ensured that blocking and ground clearance
The raised injury protection plate 402 of uneven road surface is prevented simultaneously, and simultaneous retractable reminds bar 3 to be opened from the side horizontal of trailer plate 2, flexible to carry
Awake one end of bar 3 is hinged on the side rear of trailer plate 2, and stretch the arc-shaped rack 302 for reminding the front end of bar 3 to be provided with the vertical side of trailer plate 2,
Arc-shaped rack 302 is engaged with the gear 306 being fixed on the motor 307 of the side of trailer plate 2, and motor 307 is rotated then
Flexible prompting bar 3 is propped up, a triangle prompting is formed and takes, remind the blower fan 305 being provided with inside bar to open, blower fan 305 passes through
The through hole 303 on surface is dried downwards, forms an air curtain, air curtain dries that danger so as to reminding personnel from the top down region,
When trailer straight-line travelling, then protective plate 402 and flexible prompting bar 3 are packed up and are stopped.Positioned at the protection device against pressure of underbody
5 are extreme cases for preventing personnel to be involved in underbody, and the infrared sensor in front of underbody wheel can detect bottom in real time
Face infrared signature, can be opened, lock 507 is opened then when the infrared signature for the personnel that detect by controller control lock 507
Concave-board 501 is separated with trailer bottom, and the movable slope 503 of the both sides of concave-board 501 can open elongation, forms a sky enough
Between protective cover, the personnel before wheel are covered, wheel presses through groove protective cover, it is real from the safety of protection lower section personnel
Existing protection against pressure.
