A horizontal moving supporting leg adjusting structure for double-block sleeper construction

Abstract

The utility model belongs to the field of ballastless track construction technology, concretely relates to a kind of horizontal shift support leg adjusting structure of double-block type sleeper construction, including support leg mounting seat, horizontal shift support leg, horizontal shift screw rod and horizontal screw rod sleeve;The support leg mounting seat includes the mounting seat main body of square box shape, square through-hole is provided in the lower part of mounting seat main body, and horizontal shift support leg penetrates the square through-hole;Long strip-shaped roller pin is arranged between support leg mounting seat and horizontal shift support leg;Horizontal shift screw rod is arranged in horizontal shift support leg, and horizontal screw rod sleeve is threadedly sleeved on horizontal shift screw rod, and the horizontal screw rod sleeve is fixedly connected with mounting seat main body.In the structure of the scheme, horizontal shift adjusting mechanism only contacts with support leg mounting seat through horizontal shift support leg, to reduce the contact area between the two, reduce frictional resistance;In addition, by the mode that roller pin is arranged between horizontal shift support leg and support leg mounting seat, further reduce frictional resistance, to reduce the difficulty when horizontal position is adjusted, improve adjustment accuracy.
