Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of rail measuring tools, and in particular relates to a railway turnout digital display type locking measuring ruler. Background Art
[0002] Railway turnouts are important equipment for train switching and reversing, and their working status directly affects train operation. The locking amount, as an important parameter of railway turnouts, mainly refers to the value of the overlapping part of the locking rod boss and the locking hook when the external locking device is in the locked state. The locking amount has high requirements on measurement accuracy, and the locking amount deviation on both sides of the track is required not to exceed 2mm.
[0003] However, since the locking amount measurement site is under the turnout of the track, there are basic rails, point rails, locking rods, locking frames and other components here. The track situation is complicated, there are many components of various types, and the measuring space is very narrow. At the same time, the inspection ruler is relatively short as a whole, and the distance between the scale and the measuring claws of the inspection ruler is relatively short. It is difficult for the inspection ruler to be extended under the track to measure the locking amount. Therefore, the staff is in a prone state during measurement, which causes great difficulties in measuring the locking amount and causes a blind spot in the staff's field of vision when observing the inspection ruler readings. When the staff looks at the scale line, the inspection ruler needs to be taken out from under the track at the railway turnout. When taking out the inspection ruler, it is easy to cause the position between the two measuring claws to change, which leads to inaccurate measurement accuracy. At the same time, due to the complex structure of the railway turnout track, it is impossible to determine whether the inspection ruler is placed horizontally when using it. If the two measuring claws of the inspection ruler are not on the same horizontal plane, the measurement result will be inaccurate. Utility Model Content
[0004] The utility model aims to provide a railway turnout digital display type locking measuring ruler, which can ensure that the measuring ruler is placed horizontally and make the measuring result more accurate.
[0005] The technical solution of the utility model is: a railway turnout digital display locking measurement inspection ruler, suitable for the locking rod boss and lock hook of the railway turnout locking device, including:
[0006] The main ruler comprises an integrally formed connection part and a measuring part, the connection part is provided with scale lines, one end of the connection part is provided with a level, and the level protrudes from the outer surface of the connection part; the other end of the connection part is provided with a measuring part, the length of the measuring part is 75 to 85 mm, one end of the measuring part is provided with a fixed measuring claw, the measuring part is provided with a mounting hole, and the mounting hole penetrates both ends of the measuring part;
[0007] The sliding ruler comprises a moving part and an extending part, wherein the moving part is sleeved on the outside of the connecting part, the outside of the moving part is connected with a digital display, and the outer shell of the digital display covers the moving part, and a mounting groove is opened at one end of the moving part; one end of the extending part is arranged in the mounting groove, and the extending part passes through the side wall of the digital display and is inserted into the mounting hole, and the extending part is slidably connected with the mounting hole; the other end of the extending part is provided with a moving measuring claw, and the moving measuring claw is arranged on one side of the fixed measuring claw through the mounting hole, and the moving measuring claw is parallel to the fixed measuring claw, and when the fixed measuring claw abuts against the moving measuring claw, the overall length of the inspection ruler is 225-230 mm.
[0008] Furthermore, the movable part is provided with a groove matched with the connecting part, the connecting part is provided with a scale groove, the scale groove is provided with scale lines, and the scale lines are located on one side of the digital display, when the fixed measuring jaw abuts against the movable measuring jaw, one end of the digital display is located at the 0 scale line on the main scale, when the movable measuring jaw is moved by the movable part so that it is separated from the fixed measuring jaw to the maximum distance, the distance between the movable measuring jaw and the fixed measuring jaw is 50 mm, and at this time, one end of the digital display is located at the 50 scale line on the main scale.
[0009] Furthermore, the measuring part is located on one side of the connecting part, and one end of the movable measuring jaw is in the same horizontal plane as that of the fixed measuring jaw. When the digital display moves on the main scale, the movable part is driven to move along the connecting part, and the movable part pushes the extending part to slide in the mounting hole, thereby separating the movable measuring jaw from the fixed measuring jaw, and limiting the digital display by the end of the measuring part.
[0010] Furthermore, the cross section of the connecting portion is concave-shaped, the longest width of the connecting portion is 15-18 mm, the width of the movable portion is 23-27 mm, the movable portion and the digital display are detachably connected together, and a handle is provided on one side of the housing of the digital display.

When the movable measuring claw is separated from the fixed measuring claw, the distance between the movable measuring claw and the fixed measuring claw is displayed by the digital display, and the distance reading is broadcasted by the voice module.
[0012] The beneficial effects of the utility model are as follows: the extended part of the sliding ruler is inserted into the installation hole, the overall width of the inspection ruler is reduced, and at the same time the length of the inspection ruler is extended within a suitable range, so that the staff only needs to squat to put the inspection ruler under the track at the railway switch, and place it horizontally on one side of the locking device, and at the same time, in the process of using the inspection ruler to detect the locking amount of the railway switch, the inspection ruler is kept in a horizontal state through a level meter, thereby improving the measurement accuracy; when the track blocks the staff's sight and makes the staff unable to see the scale line, the staff can accurately know the measurement result through the real-time reading of the digital display instrument, thereby preventing the accuracy from being lost due to the position change of the moving measuring claw when the inspection ruler is taken out for reading.

In view of this, the inventor of the present application provides a digital display locking amount checking ruler for railway turnouts, which can be placed under the track at the railway turnout and smoothly placed on one side of the locking device. At the same time, when using the checking ruler to detect the locking amount of the railway turnout, the checking ruler is kept in a horizontal state through a spirit level to improve the measurement accuracy.
[0024] Embodiment 1
[0025] like Figure 1-7 As shown, a railway turnout digital lock measurement inspection ruler is applicable to the locking rod boss 31 and the lock hook 32 of the railway turnout locking device 3, comprising: a main ruler 1 and a sliding ruler 2;
[0026] The main ruler 1 includes an integrally formed connecting portion 11 and a measuring portion 12. The connecting portion 11 is provided with scale lines. A level 13 is provided at one end of the connecting portion 11, and the level 13 protrudes from the outer surface of the connecting portion 11. The other end of the connecting portion 11 is provided with a measuring portion 12. The length of the measuring portion 12 is 75 to 85 mm. A fixed measuring claw 14 is provided at one end of the measuring portion 12. A mounting hole 15 is provided on the measuring portion 12, and the mounting hole 15 passes through both ends of the measuring portion 12.
[0027] The sliding ruler 2 includes a moving part 21 and an extending part 22. The moving part 21 is sleeved on the outside of the connecting part 11, and the moving part 21 can slide on the connecting part 11. The outside of the moving part 21 is connected to a digital display 23, and the outer shell of the digital display 23 covers the moving part 21. One end of the moving part 21 is provided with a mounting groove 26; one end of the extending part 22 is arranged in the mounting groove 26, and the extending part 22 passes through the side wall of the digital display 23 and is inserted into the mounting hole 15, and the extending part 22 is slidably connected with the mounting hole 15; the other end of the extending part 22 is provided with a moving measuring claw 24, and the moving measuring claw 24 is arranged on one side of the fixed measuring claw 14 through the mounting hole 15, and the moving measuring claw 24 is parallel to the fixed measuring claw 14; when the fixed measuring claw 14 abuts against the moving measuring claw 24, the overall length of the inspection ruler is 225-230 mm.
[0028] Based on the above embodiments, Figure 3 As shown, the extension portion 22 of the sliding ruler 2 is inserted into the mounting hole 15, which reduces the overall width of the inspection ruler, so that it can be placed under the track at the railway turnout and placed horizontally on one side of the locking device 3; when measuring the locking amount of the railway turnout, the movable measuring claw 24 and the fixed measuring claw 14 need to be respectively pressed against the side walls of the locking rod boss 31 and the locking hook 32, so as to obtain the length of the overlapping portion 33 of the locking rod boss 31 and the locking hook 32, and because the length of the measuring portion 12 is lengthened, the overall length of the inspection ruler is extended within a suitable range, so that the distance between the connecting portion 11 and the fixed measuring claw 14 is increased, so that the staff only needs to squat to place the fixed measuring claw 14 and the movable measuring claw 24 on the side of the locking device, and at the same time avoid the complex track conditions of the railway turnout from blocking the scale line and affecting the measurement;
[0029] In the process of measuring the locking amount of the railway turnout with the inspection ruler, the spirit level 13 is used to ensure that the inspection ruler is placed horizontally on one side of the locking device 3, that is, when the inspection ruler is placed horizontally, the bubble in the spirit level 13 is in the center of the liquid inside it, and the spirit level 13 protrudes from the outer surface of the connecting part 11, which is convenient for the staff to observe the position of the bubble in the spirit level 13.
[0030] In this embodiment, if Figure 1-4 As shown, the movable portion 21 is provided with a groove matched with the connecting portion 11, and the connecting portion 11 is provided with a scale groove 16, and the scale groove 16 is provided with scale lines, and the scale lines are located on one side of the digital display 23. When the fixed measuring claw 14 abuts against the movable measuring claw 24, one end of the digital display 23 is located at the 0 scale line on the main scale 1; when the movable measuring claw 24 is moved by the movable portion 21 so that it is separated from the fixed measuring claw 14 to the maximum distance, the distance between the movable measuring claw 24 and the fixed measuring claw 14 is 50 mm, and at this time, one end of the digital display 23 is located at the 50 scale line on the main scale 1.
[0031] Among them, the measuring part 12 is located on one side of the connecting part 11, and one end of the movable measuring claw 24 and the fixed measuring claw 14 are in the same horizontal plane. When the digital display 23 moves on the main scale 1, the movable part 21 inside it is driven to move along the connecting part 11. The movable part 21 pushes the extending part 22 to slide in the mounting hole 15, and then pushes the movable measuring claw 24 and the fixed measuring claw 14 to separate from each other, and the digital display 23 is limited by the end of the measuring part 12.
[0032] Based on the above embodiment, when the sliding scale 2 moves relative to the main scale 1, the digital display 23 abuts against the end of the measuring portion 12 to prevent the sliding scale 2 from moving out of one side of the main scale 1, and the movable measuring claw 24 abuts against the fixed measuring claw 14 to prevent the sliding scale 2 from moving out of the other side of the main scale 1.
[0033] In this embodiment, if Figure 1-3 As shown, the longest width of the connecting portion 11 is 15-18 mm, that is, the longest side of the concave cross-section of the connecting portion 11 is 14-18 mm, the width of the movable portion 21 is 23-27 mm, the movable portion 21 is detachably connected to the digital display 23, and a handle 25 is provided on one side of the housing of the digital display 23.
[0034] Based on the above embodiment, the handle 25 enables the staff to more conveniently push the digital display 23 to move, so that it drives the moving part 21 to move on the connecting part 11; when the digital display 23 is damaged, it can be removed from the moving part 21 and replaced with an undamaged digital display 23 installed on the moving part 21.
[0035] In this embodiment, a voice module is provided in the digital display 23, and a plurality of sound holes are evenly provided on one side of the digital display 23. When the movable measuring claw 24 is separated from the fixed measuring claw 14, the distance between the movable measuring claw 24 and the fixed measuring claw 14 is displayed by the digital display 23, and the distance reading is broadcasted by the voice module at the same time.
[0036] Based on the above embodiment, when the movable measuring claw 24 and the fixed measuring claw 14 are respectively against the side walls of the locking rod boss 31 and the lock hook 32, the digital display 23 displays the numerical value of the distance between the movable measuring claw 24 and the fixed measuring claw 14, and the voice module broadcasts the numerical value. When the digital display 23 is low on power and cannot be used, the distance between the movable measuring claw 24 and the fixed measuring claw 14 can also be determined by the scale lines in the scale groove 16; wherein the digital display 23 and the voice module are both conventional technical means in this field.
[0037] Embodiment 2
[0038] The difference between this embodiment and the first embodiment is that the level meter 13 provided at one end of the main ruler 1 can be replaced with a level sensor or removed, and the voice module provided inside the digital display 23 can be removed.
[0039] The working principle of the utility model is as follows: when measuring the locking amount of a railway turnout, a worker squats down and extends the main ruler 1 under the track at the railway turnout, and places the main ruler 1 on one side of the locking device 3 at the railway turnout, and abuts the fixed measuring claw 14 against the side wall of the locking rod boss 31, and moves the digital display 23 of the sliding ruler 2 through the handle 25, and the digital display 23 drives the moving part 21 to move along the connecting part 11, and the moving part 21 pushes the extending part 22 to move in the mounting hole 15, so that the moving measuring claw 24 is aligned with the fixed measuring claw 14. Separate from each other, and place the movable measuring claw 24 and the fixed measuring claw 14 against the side walls of the locking hook 32 and the locking rod boss 31 respectively to measure the length of the overlapping portion 33 between the locking rod boss 31 and the locking hook 32. At this time, the scale line at one end of the digital display 23 and the value displayed or broadcast by the digital display 23 are the distance between the movable measuring claw 24 and the fixed measuring claw 14, that is, the length of the overlapping portion 33 between the locking rod boss 31 and the locking hook 32. At the same time, the position of the bubble inside the spirit level 13 is used to ensure the horizontal state of the ruler during the measurement process.
[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
