Description

Turnout frame offset measuring device

Technical Field

The utility model relates to the technical field of turnout measurement, in particular to a turnout offset frame ruler.

Background

At present, widely used measuring tools for railway lines when laying turnouts can only measure the support distance, the track gauge and the like of a group of turnouts, but cannot measure the size of a turnout frame; moreover, there is always a blank in frame size.

In recent years, the following problems are found when laying a new turnout, replacing an original old turnout or renovating a turnout transition power-supply joint of a department of industry and business: firstly, the electric department and the industrial department often compete for data errors caused by measurement of a steel ruler because a first movable frame and a second movable frame do not have special measuring tools; secondly, the work department needs station assistance in the inspection of the turnout turning part because of the turnout rotation, and can not accurately measure the gauge measurement of the existing straight strand and curved strand and the non-close measurement of the planning and cutting part of the switch rail and the stock rail when the turnout can not rotate; thirdly, when the engineering department repairs the problem of the switch power and electricity joint in daily practice, five points of the switch point, 5mm, 20mm, 50mm and the planing end point are pressed from the point of the switch point to the point of the planing part of the switch point for each type of switch, so that the measurement error of a steel ruler is large, and the complicated operation is not beneficial to the site inspection and repair; fourthly, the detection errors of the steel rail and the steel ruler for the side grinding of the point rail are large and inaccurate due to the existence of the steel rail and the point rail point and the 5mm point position. The main reason for this is that the frame size at the switch machine cannot be measured.

In conclusion, the existing measuring tools cannot accurately measure the size of the turnout frame, and are not beneficial to daily maintenance work of turnout laying. Based on this, how to accurately measure the size of the turnout frame is a technical problem that needs to be solved by the technicians in the field at present.
