Abstract

A railway sand table turnout outtrack simulating machine comprises an indoor control circuit and an outdoor turnout controller. The outdoor turnout controller comprises a polarized relay circuit, a micro turnout outtrack driving circuit, a time relay circuit, an indication circuit and an ampere meter indication circuit. The interior control circuit is connected with the outdoor turnout controller through a line X1, a line X2, a line X3 and a line X4. The line X1 and the line X2 are connected with a turnout starting relay circuit to realize operational inputs of turnout positioning/ anti-positioning turnout; the line X3 is connected with a positioning/anti-positioning indication relay switch circuit to realize indication of the turnout positioning/ the anti-positioning turnout, and the line X4 is connected with the ampere meter indication circuit to realize visual display of the ampere meter. The railway sand table turnout outtrack simulating machine is combined with the conventional turnout control circuit to switch the sand table turnout, the turnout is tested whether to be in place or not and status of the turnout is indicated, so that actual railway site can be simulated well, and experiments and practical teaching of railway colleges and universities are facilitated.

Description

technical field [0001] The invention relates to a teaching aid for railway experiment training, in particular to a railway sand table turnout simulation switch machine for simulating the switch state of a railway sand table turnout. Background technique [0002] For the teaching of railway turnouts, in order to ensure the safety and punctuality of railway traffic, students need to go to the railway site for practice. But because it can only be watched, the practice effect cannot meet the needs of teaching. Therefore, railway colleges must build professional experiments and practice sites that are compatible with the railway field equipment and can meet the needs of practical teaching, that is, railway sand tables, for students to practice with real knives and guns during the learning process. [0003] The construction of the railway sand table can be carried out by adopting the method that the indoor equipment is consistent with the site and the outdoor equipment is simulat...
