Detailed description of the invention
As shown in Figures 1 and 2, a kind of driving safety system of Novel movable lifting table, comprises table top dolly; Described table top dolly is provided with driving safety system, and driving safety system comprises obstacle induction module 2, controller 3, sound and light alarm module 4, brake module 5; Described obstacle induction module 2, sound and light alarm module 4, brake module 5 are electrically connected with controller 3 respectively.
Described obstacle induction module 2 is ultrasonic transduter or radar, and ultrasonic transduter has that frequency is high, wavelength is short, diffraction phenomenon is little, particularly good directionality, the advantage of ray and direction propagation and less expensive can be become, suitablely to widely popularize; And radar is the locus utilizing wireless method to find target and measure them, measurement range is wide, and accuracy is high, can adapt to higher operating needs.
Described sound and light alarm module 4 comprises audible alarm 6, photoelectricity siren horn 7 and the first relay 8; Wherein, audible alarm 6 and photoelectricity siren horn 7 are relation parallel with one another, and the first relay 8 is connected on total main line; Described controller 3 is electrically connected with the signal end of the first relay 8.
