Embodiment 1

[0076] Quoting the following specific data, and substituting the data into the steps and formulas, the effect of the following sticky checker model JM-A170 / 65 is explained:

[0077]

example 1

[0078] In example 1, for the JM-A 170 / 65 model, three tests were carried out respectively, and the user-defined maximum strokes were: 130mm, 150mm and 170mm. Through the control of the logical limit switch, the actual maximum strokes measured are: 128.5mm, 150.4mm and 169.8mm respectively.

Abstract

The invention relates to a railway turnout close stick checker, in particular to a control method applied to control the normal start and stop of a push rod of a test stand of the stick stick checker. While retaining the original hardware equipment such as travel switch, displacement sensor, digital display scale, etc., the present invention introduces the concept of "logical limit switch" through software control, so that under the double protection of software and hardware, it effectively solves the problem of traditional The above deficiencies of the test bench better meet the testing needs.

Description

technical field [0001] The invention relates to a railway turnout close stick checker, in particular to a control method applied to control the normal start and stop of a push rod of a test stand of the stick stick checker. Background technique [0002] The test bench for the closeness checker is mainly used to test the various characteristics of the closeness checker of the railway turnout, including the horizontal driving force, displacement, insulation resistance and other parameters indicating the pull-in and extension of the rod. When testing the action characteristics of the close stick checker in the traditional test bench, it is necessary to set a travel switch at each end of the stroke to control the normal start and stop of the push rod. Although this structure is simple in design and easy to implement, it also has the following defects: [0003] 1. The position of the travel switch needs to be adjustable to meet the needs of different models and different strokes...
