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.

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 utility model discloses switch close-fitting inspection ware can inspect the close-fitting state and the inspection switch rail of switch tongue by repulsing from the distance of position to close-fitting displacement to repulsing from the adjustment seat through the adjustment, adaptation inspection point department repulses from the switch opening of switch tongue at 60mm ~ 175mm within range and moves, is connected with the microcomputer monitoring through displacement sensor information strip, realizes full journey supervision to the switch rail state.
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.
