When the vehicle bumps with protector, protective part 3 is to the preliminary cushioning effect of vehicle and personnel, and the corresponding energy storage component of tip coexistence cylinder plays the cushioning effect equally, and simultaneously, anticollision part is compressed and then through connecting spring linkage both sides connector between the stand jointly to vehicle kinetic energy absorb and spread comprehensively, and then ensure vehicle and personnel's safety.
The speed sensor 6 detects the speed of the vehicle reaching the diversion line, the detected speed is received by the data acquisition unit and fed back to the controller 8, the controller processes information to enable the high-speed camera 9 to work, the condition of the diversion line of the ramp is photographed and processed and transmitted to the terminal, the terminal is connected with the controller, the terminal makes judgment and sends a signal to the controller;
the controller is according to the signal that vehicle detector and speedtransmitter sent, the vehicle detector detects the vehicle, and speedtransmitter judges the speed of vehicle, if the speed that detects is greater than the speed of settlement, and cooperation force sensor's detection, at this moment, the controller confirms the bump, the wheel 23 that anticollision part has locked is opened to the controller, make anticollision part can remove along with the removal of vehicle, play preliminary cushioning effect through the setting of anticollision part once more, and simultaneously, anticollision part 3 is compressed and then through connecting between the stand body spring linkage both sides connector jointly to the vehicle with can fully absorb and spread, the great kinetic energy of dispersion vehicle, and then ensure vehicle and personnel's safety.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
