[0007] Furthermore, a mounting hole matching with a limiting bolt at the end of the point rail is opened at one end of the fixing plate, and the limiting bolt is inserted into the mounting hole to fix the fixing plate.

[0008] Furthermore, a positioning box is provided at one end of the fixing plate, the displacement sensor is arranged in the positioning box, and the end of the detection rod extends out of the positioning box.

[0009] Furthermore, a positioning plate is provided at one end of the fixing plate, the positioning plate is vertically arranged with respect to the fixing plate, and the positioning box is fixed on the positioning plate.

[0010] Furthermore, a rib is provided between the adjacent plate surfaces of the positioning plate and the fixing plate.

[0011] Furthermore, the mounting holes include a pair, the pair of mounting holes are arranged at intervals, and each of the mounting holes is a U-shaped structure.

[0012] Furthermore, one end of the displacement sensor is connected to a turnout integrated monitoring system, and the turnout integrated monitoring system is used to display the amount of close contact detected by the displacement sensor.

[0013] Furthermore, the cross section of the fixing plate is a “[”-shaped structure.

[0014] The utility model adopts the above technical solution, which has the following advantages and effects:

[0015] The utility model provides a device for measuring the close fit of a pointed rail, which detects the close fit of the pointed rail after it moves to the base rail by fixing a displacement sensor on the end of the pointed rail. Since the end of the pointed rail cannot be processed in any way, the utility model fixes the displacement sensor by arranging a mounting hole on a fixing plate that matches a limit bolt on the end of the pointed rail, does not damage the structure of the original pointed rail, saves costs, and simultaneously measures with the displacement sensor, has high measurement efficiency, and can perform real-time monitoring.

The utility model is a device for measuring the close contact of a point rail, comprising a fixing plate 2, one end side of the fixing plate 2 is fitted on the inner side of the end of the point rail, the other end of the fixing plate 2 extends out of the end of the point rail, and a displacement sensor 5 is arranged at the other end of the extending fixing plate 2, and a detection rod 501 of the displacement sensor 5 extends toward one side of the base rail and extends out of the outer side of the point rail. A mounting hole 201 matching with a limit bolt at the end of the point rail is provided at one end of the fixing plate 2, and the limit bolt is inserted through the mounting hole 201 to fix the fixing plate 2.

[0024] Specifically, the fixing plate 2 is a steel plate, and the upper and lower ends of the fixing plate 2 are respectively provided with flanges extending toward one side of the plate surface, so that the cross section of the fixing plate 2 is a "["-shaped structure, and the upper end surface of the fixing plate 2 is not higher than the upper end surface of the point rail. The mounting hole 201 passes through the plate surface of the fixing plate 2. The detection rod 501 of the displacement sensor 5 is perpendicular to the fixing plate 2, so that when the point rail is aligned with the base rail, the end of the detection rod 501 is perpendicular to the surface of the base rail.

[0025] The displacement sensor 5 is a mechanical displacement sensor.

[0026] Furthermore, since there is a pair of limit bolts at the end of the point rail, and the front end of the point rail cannot be processed at will, the mounting holes 201 also include a pair, and the pair of mounting holes 201 are arranged at intervals to correspond to the pair of limit bolts, ensuring that the fixing plate 2 is fixed to the point rail through the mounting holes 201 without damaging the point rail. In order to facilitate the adjustment of the extension distance of the fixing plate 2, each mounting hole 201 is a U-shaped long slot hole.

[0027] Furthermore, in order to protect the displacement sensor 5, a positioning box 1 is provided at one end of the fixed plate 2. The positioning box 1 is a rectangular box body with a detachable upper cover. A slot for the detection rod 501 to pass through is opened at one end of the positioning box 1. The outer peripheral surface of the positioning box 1 is perpendicular to the end of the fixed plate 2. The displacement sensor 5 is arranged in the positioning box 1, and the detection rod 501 of the displacement sensor 5 extends out of one end of the positioning box 1 through the slot.

[0028] Specifically, an I-shaped slot is provided on the side wall of the positioning box 1, and a pair of flange plates are embedded in the slot, and the ends of the flange plates extending out of the slot respectively fix the two ends of the displacement sensor 5. Screw holes are provided on the flange, and after adjusting the position of the flange in the slot, the position of the flange is tightened by screws passing through the screw holes, and then the displacement sensor 5 is fixed on the flange.

[0029] Furthermore, in order to facilitate further fixation of the positioning box 1, a positioning plate 4 is provided at one end of the fixing plate 2, and the end of the positioning plate 4 and the end of the point rail extending from the fixing plate 2 are vertically arranged to form an L-shaped structure. The positioning box 1 is arranged on the outer surface of the positioning plate 4, and the outer peripheral surface of the positioning box 1 is fitted with the outer side surface of the positioning plate 4, and the two are fixedly connected by screws.

[0030] Furthermore, in order to strengthen the connection between the positioning plate 4 and the fixing plate 2, a rib plate 3 is provided between the adjacent plate surfaces of the positioning plate 4 and the fixing plate 2. The rib plate 3 is a right triangle structure, one vertical side of which is fixed on the positioning plate 4, and the other vertical side is fixed on the fixing plate 2.

[0031] Furthermore, in order to detect the amount of close contact of the point rail in real time, one end of the displacement sensor 5 is connected to the turnout integrated monitoring system, and the displacement sensor 5 can transmit the close contact amount to the turnout integrated monitoring system in real time, and the turnout integrated monitoring system can be used to display the detected close contact amount, so that the staff can view the close contact amount information of the point rail in real time to ensure that the point rail works normally.

[0032] When the utility model is in use, the fixing plate 2 is fixed by the limit bolt at the end of the point rail, and then the point rail is controlled to fit with the basic rail, and the detection distance is reset to zero after the extension length of the detection rod 501 of the displacement sensor 5 is adjusted, and then the point rail is reset. During each track change adjustment, when the point rail moves closer to the basic rail, the detection rod 501 of the displacement sensor 5 will fit toward the side of the basic rail to realize detection.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it.
