At the same time, in the description of this utility model, the terms "first", "second", etc. are used only to distinguish the description and should not be understood as indicating or implying relative importance.

[0031] Example 1:

[0032] like Figures 1 to 3 As shown, a track ruler for measuring a rack railway track comprises:

[0033] A track ruler base 1, with gauge action blocks 10 fixedly provided on both sides of the bottom of the track ruler base 1, a clamping slot provided in the middle of the bottom of the track ruler base 1, a first mounting slot 11 provided on one side of the bottom of the clamping slot, a positioning slot 13 provided on the other side of the bottom of the clamping slot, and a second mounting slot 12 provided on the positioning slot 13 at a position directly opposite the first mounting slot 11; and

[0034] The positioning device includes a first sliding roller 2, a second sliding roller 3 and an elastic member. The first sliding roller 2 is arranged in the first mounting groove 11, and the first sliding roller 2 can rotate in the first mounting groove 11. The second sliding roller 3 is arranged in the second mounting groove 12. The elastic member is arranged in the positioning groove 13, and one end of the elastic member is fixedly connected to the bottom of the positioning groove 13, and the other end of the elastic member is fixedly connected to the outer wall surface of the second sliding roller 3.

[0035] In this ruler structure, the card slot can be set as a rectangular card slot with a height of 100 mm, a width of 63 mm, and a thickness of 50 mm, and the first sliding roller 2 and the second sliding roller 3 can be set as sliding rollers with a diameter of 5 mm and a length of 40 mm.

[0036] When using this track gauge to check the line on the track, the track gauge should be calibrated first.

[0037] like Figure 6 As shown, the center of the slot in the gauge base 1 is aligned with the top of the rack teeth of the cog railway. The rack is then inserted into the slot to the preset installation height, and the ends of the gauge base 1 are observed to ensure close contact with the top surfaces of the left and right rails. Furthermore, the gauge action block 10 is positioned at a 90° angle to the left and right rails of the cog railway before the gauge data is read. During this process, the introduction of the elastic member enables the second sliding roller 3 to provide an adjustable horizontal guiding force. The first sliding roller 2 can provide a circumferential guiding force based on its contact position with the cog railway rack. When the two ends of the track gauge base 1 are fully in contact with the top surfaces of the left and right rails, measure the distance between the left side of the rack and the preset height below the top surface of the inner rail of the left rail head. Similarly, measure the distance between the right side of the rack and the preset height below the top surface of the inner rail of the right rail head. According to the measured left and right track gauge data, the fault of the rack railway track is diagnosed. Since the sum of the left and right track gauges is the track gauge of the two rails, if the left and right track gauge data are the same, it means that the rack of the rack is at the center of the line. Otherwise, it means that the rack deviates from the center of the line. According to the difference between the left and right track gauges and the line direction, it is determined whether the rerouting operation is to move the rack or the left and right rails.

[0038] This ruler can be used for measuring meter gauge rack rails.

[0039] In addition, in this ruler, an electronic height scale can be set at the top of the slot based on the principle of light sensing, which is used to display the height difference between the top surface of the rack and the top surfaces of the left and right rails on the longitudinal section.

[0040] When one end of the elastic member is fixedly connected to the bottom of the positioning groove 13 and the other end of the elastic member is fixedly connected to the outer wall of the second sliding roller 3, since the second sliding roller 3 is a rotating body, the elastic member and the outer wall of the second sliding roller 3 are more connected at a single point. When the second sliding roller 3 has a large rotation angle, the connection structure of the elastic member needs to be strengthened.

[0041] For this reason, Figure 4 As shown, a rectangular groove 31 is provided in the radial direction of the second sliding roller 3. The rectangular groove 31 corresponds to the position of the positioning groove 13. One end of the elastic member is fixedly connected to the bottom of the positioning groove 13, and the other end of the elastic member is fixedly connected to the groove wall of the rectangular groove 31. In this structure, the groove wall of the rectangular groove 31 can provide multiple planar connection points. The end of the elastic member closest to the rectangular groove 31 is compressed in the elastic member to ensure stable connection with the multiple planar connection points, thereby ensuring the stability of the connection between the elastic member and the second sliding roller 3.

[0042] The elastic member can be a spring.

[0043] In order to ensure that the first sliding roller 2 provides a stable guiding force, a fixed rod 5 is introduced. Both ends of the first sliding roller 2 are provided with convex shafts. One end of the fixed rod 5 is rotatably connected to the convex shaft, and the other end of the fixed rod 5 is fixedly connected to the outer wall of the ruler base 1.

[0044] In this track gauge, a track gauge operation handle 61 and a track gauge measuring device are introduced to facilitate the track gauge measurement operation. The track gauge measuring device is arranged on both sides of the track gauge operation handle 61. The track gauge measuring device includes a track gauge inspection ring 62, a scale 63 and a steel rope 64. The track gauge operation handle 61 is fixedly arranged on the top of the track gauge base 1, and the position of the track gauge operation handle 61 corresponds to the position of the card slot.

[0045] The bottom of the track gauge base 1 is provided with a sliding groove on both sides, the top of the gauge action block 10 is fixedly provided with a sliding block, the sliding block is in sliding cooperation with the sliding groove, the inside of the track gauge base 1 is provided with a scale installation groove and a steel rope installation groove, a horizontal reading window 65 is arranged on the outside of the scale installation groove, the scale 63 is arranged in the scale installation groove, and the steel rope 64 is arranged in the steel rope installation groove; when the track gauge inspection handle 62 is fixedly connected to the rail gauge operation handle 61, one end of the scale 63 is fixedly connected to the track gauge inspection handle 62 through the steel rope 64, and the other end of the scale 63 is fixedly connected to the rail gauge action block 10 through the steel rope 64. In the structure, the scale 63 can be an electronic scale made according to the light induction principle. The horizontal reading window 65 is used to read the horizontal position of the left and right steel rails on the line longitudinal section.

[0046] In addition, in the structure, the track gauge inspection handle 62 can be lifted or lowered to realize the inspection of the inspection distance and the back protection distance at the frog heart of the tooth rail turnout, and the data is read at the horizontal reading window.

[0047] Further, in order to facilitate flexible measurement of different rail gauges, a reset spring 60 is further arranged between the track gauge inspection handle 62 and the scale 63, the inside of the track gauge base 1 is provided with a reset spring installation groove, the reset spring 60 is arranged in the reset spring installation groove, one end of the reset spring 60 is fixedly connected to the track gauge inspection handle 62 through the steel rope 64, and the other end of the reset spring 60 is fixedly connected to the scale 63 through the steel rope 64; when the measurement of the tooth rail track is performed, the reset spring 60 is in a compressed state.

[0048] In order to facilitate the lifting and lowering operation of the track gauge, a track gauge handle 66 is introduced, the track gauge handle 66 is arranged on the outside of the rail gauge operation handle 61, and the bottom of the track gauge handle 66 is fixedly connected to the top of the track gauge base 1.

[0049] As shown in Figure 5 In order to meet the operation requirements of the tooth rail track circuit area, an insulating sleeve 7 is sleeved at both ends of the track gauge base 1 in the track gauge.

[0050] When the rack of the rack railway is distorted under the action of external force, a gap will be generated between the gauge and the top surface of the steel rail to be measured, so that a horizontal line of the gauge and the top surface of the steel rail to be measured will form an angle, and the measurement data in this case is error data, if the line maintenance and repair is carried out according to the error data, the driving safety will be seriously endangered. Therefore, such a situation must be strictly prohibited. Therefore, distance sensors 8 are arranged on both sides of the bottom of the gauge base body 1, the distance sensors 8 are arranged on the outer side of the track gauge acting block 10, and the outer side of the track gauge acting block 10 is the side away from the clamping groove. Further, in order to realize the feedback of the cooperation between the gauge and the top surface of the steel rail to be measured, a warning device 9 is introduced, the warning device 9 is arranged on the top of the gauge base body 1, and the warning device 9 is electrically connected with the distance sensor 8. In this structure, if the cooperation between the gauge and the top surface of the steel rail to be measured meets the preset distance requirement, the warning device 9 will not respond; when the cooperation between the gauge and the top surface of the steel rail to be measured does not meet the preset distance requirement, the warning device 9 will generate a warning instruction. The warning device 9 can be a buzzer or a red warning light. At this time, the operator needs to check the gauge, the line and the rack, and determine the cause, and then process the problem according to the cause, such as replacing the deformed and skewed rack fastener, adjusting the distorted rack bar.
