Abstract

The invention relates to the field of drawing devices, in particular to a tripping-preventing drawing device. The tripping-preventing drawing device comprises a screw rod. The screw rod is provided with a screw rod seat, and three drawing claws are evenly distributed around the screw rod seat. The drawing claws are hinged to the screw rod seat, and a triangular-prism-shaped drawing claw fixing frame is arranged on the outer side of the screw rod seat. A threaded hole is formed in the middle of the upper portion of the drawing claw fixing frame, and the screw rod penetrates the threaded hole inthe middle of the drawing claw fixing frame. A drawing claw sliding groove is formed in the lower portion of the drawing claw fixing frame. The drawing claws penetrate the drawing claw sliding groove.

Description

Technical field [0001] The invention relates to the field of pullers, in particular to an anti-trip puller. Background technique [0002] The puller is a device that takes the inner bearing out of the bearing housing. It includes a mounting plate, tension bolts and through-wire bolts; there are no less than two tension bolts, and the bottom of each tension bolt can hang the bottom of the inner bearing The pull claw of each pull bolt is equipped with a fastening nut, and there is no less than one long hole in the middle of the mounting plate. The width of the long hole is greater than the diameter of the pull bolt, and the lower end of each pull bolt passes through the long hole And stretch to the bottom of the mounting plate, the fastening nut can be clamped on the mounting plate at the long hole; at least two positioning nuts are fixed on the mounting plate outside the long hole. When pulling heavy objects, the general puller often has three pull claws that are misplaced, causi...
