In this embodiment, the distance between the close contact position and the repulsion position can be changed by arranging the repulsion adjusting seat 34, arranging the second speed plate 31 on the repulsion adjusting seat and adjusting the position of the repulsion adjusting seat 34 in the groove 12, so that the inspection rod can be flexibly adjusted according to the stroke distance of the actual turnout, and the repulsion state of the turnout switch rail can be correctly reflected.
In this embodiment, the distance between the repulsion inclined plane and the close contact inclined plane on the repulsion adjusting seat 34 can be increased from 60mm to 175mm, and the adjustable range of the stroke is large, and the application range is wide.
In this embodiment, the bottom of the groove of the square rod 11 is further provided with a fixing plate 4, the fixing plate 4 is fixed at the bottom of the groove, the upper surface of the fixing plate 4 is provided with a transverse strip-shaped tooth 41, the separation-repelling adjusting seat 34 is movably fixed on the fixing plate 4 through a bolt 5, and the lower surface of the separation-repelling adjusting seat 34 is provided with a meshing tooth 341 matched with the transverse strip-shaped tooth 41.

Referring to fig. 4 to 6, the operation principle of the switch closure checker of the present embodiment is as follows:
1. the switch rail at the point of the switch inspection point is displaced from the close contact position to the repulsion position. Fig. 4 shows the point at the switch checkpoint in the closed position, and the switch indicates that the point is in the closed state. Figure 5 shows the point rail driving the inspection bar 1 to move to the left, the switch indicating that the circuit is open and closed, and the point rail being in motion. When the switch rail drives the inspection rod 1 to continuously move to 10-25 mm (adjustable) before the specified stroke, the arc sharp corner of the starting sheet 9 contacts with the second speed moving sheet 31, the roller 10 contacts with the repulsion adjusting seat 34 at the repulsion inclined plane 341, and continuously moves to the repulsion plane 342 of the roller 10 and the repulsion adjusting seat 34, at this time, the switch indicates that the repulsion in the circuit indicates that the contact is completely connected, the second speed moving sheet 31 resets under the action of the second spring 32, and then continuously moves until the specified stroke is reached, and the switch rail is in the repulsion position, as shown in fig. 6. The opening movement at different inspection points can be realized by adjusting the position of the repulsion adjusting seat 34.
2. The switch rail at the point of the switch inspection point is displaced from the repulsion position to the close contact position. Under normal switching, as shown in fig. 6, the switch rail drives the inspection rod 1 to move rightwards, the arc sharp corner of the starting piece 9 is separated from the second speed moving piece 31, when the switch is moved down quickly, the switch shows that the repulsion in the circuit shows that the contact is disconnected, the inspection rod 1 continues to move rightwards, when the close contact position is reached, the arc sharp corner of the starting piece 9 is separated from the first speed moving piece 11, and the close contact in the circuit shows that the contact is connected. However, in abnormal situations, when the point rail is in the repulsion position, the inspection rod 1 is displaced to the close contact position due to external force, when the displacement distance is smaller than the specified movement distance and is too large, the circular arc point of the starting piece 9 is separated from the second speed piece 31, the point rail rapidly falls down, the repulsion indicating contact in the turnout indicating circuit is disconnected, the inspection of the point rail in the repulsion position is realized, and the abnormality of the point rail in the repulsion position can be judged. When the switch rail reaches the close contact position, and a gap exists between the switch rail and the stock rail or the geometric dimension of a foreign object is larger than a specified value, the circular arc sharp corner of the starting piece 9 cannot be separated from the first quick action piece 11, the close contact in the turnout indication circuit indicates that the contact cannot be connected, and the check of the switch rail at the close contact position is realized.
In the process of the switch rail action, the switch rail displacement information is fed back to the collector through the displacement sensor information strip on the inspection rod 1, and the collector transmits the collected information to the microcomputer for monitoring, so that the full-stroke supervision of the switch rail is realized.
The switch closure checker of the invention can check the closure state of the switch tongue and the displacement distance of the switch tongue from the repulsion position to the closure position, adapts to the switch opening movement of the switch tongue at the check point within the range of 60 mm-175 mm by adjusting the repulsion adjusting seat, and realizes the full-movement supervision of the switch tongue state by connecting the displacement sensor information strip with the microcomputer monitoring.
Still through setting the inspection rod to one end for square pole, one end is circular pole, has both possessed the switch tongue and has sealed the subsides and repel from inspection function, possesses good dustproof and waterproof, wear-resisting function again.
