Traversing type hydraulic rerailer

Abstract

The invention discloses a transverse moving type hydraulic rerailer. A rerailing beam is in a groove-shaped structure with an upward opening, and two sliding rails are fixed to the top ends of two side plates of the rerailing beam in the full length; a moving table capable of sliding left and right is arranged on the sliding rails; a transverse moving cylinder is mounted in the groove-shaped structure, the right end of the transverse moving cylinder is hinged to the right end of the rerailing beam through a first pin shaft, and the left end of the transverse moving cylinder is hinged to the left end of the moving table through a second pin shaft; the bottom ends of two jacking cylinders arranged in a herringbone form are respectively hinged to the moving table through supporting pin shafts; and the piston ends of the two jacking cylinders are symmetrically hinged to positions under a jacking head, so that a triangular stable structure is formed by the moving table, the two jacking cylinder and the jacking head through mutual connection. According to the traverse moving type hydraulic rerailer disclosed by the invention, a jacking part adopts the triangular stable structure, and a traverse moving part adopts a sliding structure, so that not only is the stability of the rerailer during rerailing improved, but also the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of railway equipment, and in particular relates to a traverse type hydraulic rerailer. Background technique [0002] Existing hydraulic rerailers all adopt a single-cylinder or double-cylinder vertical structure, which is prone to dumping accidents when they are greatly hindered during traverse; the traverse mechanism adopts the form of a trolley, and the trolley is equipped with rollers. The bearing pressure is high, and although the friction of the roller structure is small, it requires high strength of the rerailing beam. The number of rollers is generally 6 or 8, which requires high machining accuracy and high manufacturing costs. Contents of the invention [0003] The invention provides a lateral movement type hydraulic rerailer. The jacking part adopts a triangular stable structure, and the lateral movement part adopts a sliding structure, which not only improves the stability of the rerailer during ...
