Support type rescue restarting equipment with hydraulic oil cylinders at two sides for motor train unit

Abstract

The invention relates to support type rescue restarting equipment with hydraulic oil cylinders at two sides for a motor train unit, which is characterized by comprising two single-stage lifting oil cylinders, wherein the two single-stage lifting oil cylinders are arranged on a sole timber through protecting seats fixedly connected with the two single-stage lifting oil cylinders, positioning lifting jacks are respectively arranged below trolley edge beams, the upper planes of the positioning lifting jacks come into contact with corresponding edge beams of trolleys of the motor train unit, and the lower spherical surface of each positioning lifting jack is arranged in a ball impression of a corresponding three-stage double-function oil cylinder; and two transverse-moving trolleys are connected through a traction connecting rod to form a transverse-moving trolley unit, two three-stage double-function oil cylinders are respectively arranged on the transverse-moving trolleys, a gap between the two transverse-moving trolleys is adjusted by using a length adjusting screw rod, a transverse-moving oil cylinder arranged in one of the transverse-moving trolleys is arranged in a groove of a transverse-moving beam, and a trolley anti-skidding device is arranged on one of the two transverse-moving trolleys. The support type rescue restart equipment has the advantages of steady and reliable restarting operation, good safety, rapidity and high accuracy, short rescuing time and the like, can meet the requirement ona gap of 160mm between the lowest plane of the trolley edge beam of the motor train unit and a track plane, and realizes one-step accurate restarting operation.

Description

technical field [0001] The invention relates to other auxiliary equipment used for railways, which is a double-side hydraulic oil cylinder supporting type rescue recovery equipment for a multiple train set, which is used for rescue and rerailing operations when the multiple train set is derailed. Background technique [0002] In the existing rescue of EMU derailment, first of all, two single-stage lifting cylinders are used to correspond to the lifting support points on both sides of the EMU car body, and the single-stage lifting cylinders are placed on the ground through the protective seats fixed to them. On the skid, operate the single-stage lifting oil cylinder, the piston rod of the single-stage lifting oil cylinder rises, and the car body and trolley of the EMU are simultaneously jacked up to a certain height. Then, the traversing beam is placed in the middle position below the side beam of the EMU trolley, and two traversing trolleys are placed on the traversing beam,...

AI Technical Summary

Problems solved by technology

Its disadvantages are: during the hoisting operation process, the single-stage hoisting cylinder needs to lift the EMU car body repeatedly at least twice; the hoisting operation process is cumbersome, and the rescue time is long

The prior art has not yet seen: the literature report and practical application of the EMU double-sided hydraulic cylinder supported rescue lifting equipment that directly supports the side beam of the trolley and can complete the lateral movement and reset at one time.
