Description

Technical Field

[0001] The utility model relates to the technical field of railway measurement, in particular to a passenger dedicated track turnout frog reduction value measuring device. Background Art

[0002] Turnout products are assembly parts, and various rail parts are assembled together through bolts, spacers, limiters and other parts. After the rail parts are combined together, whether the reduction values ​​between various rail parts meet the requirements affects the wheel-rail contact during use. When the reduction value exceeds the tolerance, it will cause the rail parts to wear faster and affect the smooth operation of the train. After the passenger dedicated switch drawings are unified, the reduction values ​​of the long and short heart rails, short heart rails and fork and tip rails of the switch part need to be measured group by group in the factory. However, the current measuring tools cannot meet the measurement needs. Therefore, the development of this utility model patent is to solve the problem of factory measurement of the reduction values ​​of the long and short heart rails, short heart rails and fork and tip rails, and ensure that the detection points of the reduction value of the passenger dedicated switch can be measured and controlled.

[0017] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0018] The utility model provides a device for measuring the reduction value of a passenger-dedicated track turnout frog accurately, comprising a level ruler 1, a measuring ruler 2, a digital display cursor 3, a magnetic slider 4, and a level bubble 5. Figure 1 shown.

[0019] The measuring ruler 2 is a straight ruler, which is set vertically; the lower end of the measuring ruler 2 is a horizontal plane, and the left side of the bottom end is an inclined plane that tilts to the right at the bottom. The digital display cursor 3 is slidably fitted on the measuring ruler 2. Connecting feet 6 are designed on the left and right sides of the bottom end of the digital display cursor 3. The back sides of the connecting feet 6 on both sides are flush with the back side of the digital display cursor 3 shell, and the bottom edge is flush with the bottom surface of the digital display cursor 3 shell. At the same time, through holes are opened at the outer ends of the connecting feet 6 on both sides for connecting the level ruler 1; when connected, the digital display cursor 3 and the back sides of the connecting feet 6 on both sides of it fit the front of the level ruler 1, so that the through holes on the connecting feet 6 on both sides of the digital display cursor 3 correspond to the two screw holes opened in the middle of the level ruler 1, and the bolts are passed through the through holes and connected to the screw holes; at the same time, the digital display cursor 3 is fine-tuned so that the bottom surface of the digital display cursor 3 and the bottom surface of the connecting feet 6 on both sides are coplanar with the bottom surface of the level ruler 1, ensuring that the measuring ruler 2 and the level ruler 1 are vertical. Thus, the digital display cursor 3 and the level ruler 1 are fixed, so that the measuring ruler 2 can move up and down in the vertical direction, and the moving distance is displayed on the display screen of the digital display cursor 3. A threaded hole is provided on the housing of the digital display cursor 3, and a tightening bolt 7 is threadedly installed to fix the position of the measuring ruler when the measuring ruler 2 moves vertically into place.

[0020] On the level ruler 1, magnetic sliders 4 are sleeved on both sides of the digital display cursor 3, and the magnetic slider 4 has a slider part 401 and a magnetic part 402; wherein the slider part 401 is sleeved on the level ruler 1 through a through hole opened thereon; a groove is opened on the bottom surface of the slider part 401, and a magnet is fixedly installed in the groove to form the magnetic part 402. At the same time, limit screws 101 are installed at the left and right ends of the level ruler 1 to limit the slider part 401 and prevent the slider part 401 from being separated from the level ruler 1.

[0021] A level bubble 5 is also installed at any position on the top edge of the level ruler 1 to detect the horizontality of the level ruler 1; at the same time, through holes are provided at equal intervals in the length direction of the level ruler 1 to reduce the weight of the level ruler 1.

[0022] When measuring the lowering value of the turnout frog on the passenger dedicated track, the above structure measuring ruler is used. Figure 2 As shown:

[0023] First, slide the two magnetic sliders 4 along the level ruler 1 so that the two magnetic sliders 4 are respectively adsorbed on the center position of the top surface of the two side wing rails, so that the direction of the level ruler of the measuring device is perpendicular to the direction of the rail to be measured; further, confirm the horizontal condition of the level ruler 1 by observing the level bubble 5.

[0024] According to the horizontal condition of the level ruler 1, the height of the magnetic slider 4 is fine-tuned by inserting a feeler gauge between the bottom surface of the magnetic slider 4 and the top of the rail to ensure that the level ruler 1 is horizontal.

[0025] Subsequently, since the position between the magnetic slider 4 and the rail is fixed, the horizontal position of the measuring ruler 2 can be adjusted by horizontally moving the level ruler 1, so that the measuring ruler 2 can reach the two rails above the measured characteristic section position to measure the height difference, specifically:

[0026] The two rails at the characteristic section position are the long center rail and the short center rail; the long center rail is used as the reference rail, and the measuring ruler 2 is first moved to the top of the long center rail, and then the measuring ruler 2 is moved down, and the horizontal position of the measuring ruler 2 is adjusted so that the bottom end face of the measuring ruler 2 contacts the highest point of the reference rail, and the reading of the digital display cursor 3 is reset to zero. The measuring ruler 2 is further moved to the top of the short center rail, and the measuring ruler 2 is moved down, and the horizontal position of the measuring ruler 2 is adjusted so that the bottom end face of the measuring ruler 2 contacts the highest point of the short center rail. At this time, the value displayed on the digital display cursor is the reduction value of the short center rail relative to the long center rail at the current characteristic end face. The measurement process is simple and the result is accurate.

[0027] In the above measurement process, the measuring surface of the measuring ruler 2 (the bottom end surface of the measuring ruler 2) is reduced by designing the lower end inclined surface of the measuring ruler 2, so that the measuring ruler 2 is not affected by the adjacent rail members during measurement.

[0028] After the above measurement is completed, the position of the measuring ruler 2 can be locked by tightening the tightening bolt 8 to prevent the measuring ruler 2 from sliding and causing measurement errors; after locking, the reading can be taken directly or after the level ruler 1 is removed.
