Description

Technical Field

[0001] The utility model provides a route-changing device, belongs to the technical field of track equipment, and particularly relates to a hydraulic digital display route-changing device used for tracks. Background Art

[0002] Track is the most basic component of the railway system. It consists of two parallel steel rails and is used to carry and guide trains. The definition of track includes geometric parameters such as gauge, superelevation, and track direction, which directly affect the safety and comfort of train operation. Rerouting the track means optimizing line conditions and improving the quality of train operation by adjusting the track geometric parameters. The significance of rerouting is to eliminate or reduce track unevenness, improve train operation stability, increase driving speed, extend track service life, and reduce maintenance costs.

[0003] Most existing diversion methods use a crowbar or a gauge precision change rod to divert the track. The gauge precision change rod is mainly used for ballastless tracks that are difficult to pry with a crowbar. It consists of a gauge rod and a wrench. When in use, first use a track ruler or precision measuring instrument to detect the gauge and track deviation values, then use a crowbar or a gauge precision change rod to move the track laterally, and tighten the fixing bolts with a wrench, and finally measure again to ensure that the gauge and track reach the standard value. However, both tools have many disadvantages. When the crowbar pries the rail, the rail needs to be tilted and lifted, and some sections are difficult to pry. When the gauge precision change rod is used, the diversion rod hook needs to be placed at the bottom of the rail. The equipment is heavy, troublesome to install, inconvenient to use, and the translation amount cannot be displayed intuitively. Utility Model Content

At the same time, a fixing member 22 is installed on the top of the fixing bolt 17, so that the hydraulic telescopic device 12 is driven with the fixing bolt 17 as a fixed fulcrum, and then the gasket 21 is driven to support the rail 1 and move, thereby realizing diversion; the fixing member 22 and the fixing bolt 17 have corresponding shapes.

[0027] It should be noted that the digital display sensor 13 is one of a displacement sensor, an encoder, a laser ranging sensor, a magnetic position sensor or a photoelectric encoder.
