The specific embodiment
Fig. 1 to Fig. 2 below in conjunction with accompanying drawing is described in further detail a kind of gravity Fast closing gate lifter of the present utility model.
A kind of gravity Fast closing gate lifter of the present utility model, please refer to Fig. 1 to Fig. 2, comprise electric device for valve 1, electromagnetic clutch 4, damper 3, snubber 5, ball screw spiral secondary 7 and base 2, described damper 3 arranges the below with described electromagnetism electromagnetic clutch 4, described snubber 5 is connected with the leading screw 6 of described ball screw spiral pair 7, described base 2 is fixed on cement beam or the steel member, described electromagnetic clutch 4 and secondary 7 interlocks of described ball screw spiral, described electromagnetic clutch 4 comprises axle 11 and clutch lower shaft 13 on the clutch, described clutch lower shaft 13 and cylindrical gear pair 14 interlocks of described ball screw spiral secondary 7 by a pair of periphery engagement, being specially feed screw nut 15 fixes with roller gear, described clutch lower shaft 13 lower ends and a roller gear are fixed, and described ball screw spiral secondary 7 and another roller gear are fixed.Like this, this moves on the feed screw nut 15 of ball screw spiral pair 7 by cylindrical gear pair 14 transmission in the axle rotation on the electromagnetic clutch 4, so that feed screw nut 15 runnings and then drive leading screw 6 rise or descend, finishes the keying of quick-closing gate.Further preferred technical scheme is that described ball screw spiral pair 7 comprises leading screw 6 and feed screw nut 15, and described leading screw 6 and feed screw nut 15 interconnect.Like this owing to using cylindrical gear pair linkage clutch lower shaft and the described ball screw spiral pair of a pair of periphery engagement, the direction of rotation of drive unit transmission is opposite like this, namely can use the ball screw spiral of right-spiral secondary, greatly save cost and can use the general right-spiral ball screw spiral of domestic contrast secondary.And can be so that the operation of handwheel meets national standard and industry operating habit.
