Clamping rail mechanism prevents toppling

The utility model relates to a clamping rail mechanism prevents toppling belongs to track device technical field, relates to the rail locking mechanism of rail -engaging equipment, and including mount pad and clamping rail pincers, the key lies in in the structure: including the splint of two block types body symmetry in the clamping rail pincers, articulate with the help of the minor axis and form rocker formula structure in the both sides of the mount pad of T shape, pass reverse -flighted screw and location among the opening and closing driving mechanism drive nut that shifts in the opening of splint upper end, the splint lower extreme is and hook -likely forms the matching of preventing toppling with the track I -steel. This clamping rail mechanism utilizes two splint upsets of reverse -flighted screw drive to open and shut, and the pine leaves or the locking track is rapid and reliable, overall structure is simple, convenient operation, can avoid the handling equipment lapse and tumble, and factor of safety is high.
