Description

Technical Field

[0001] The utility model relates to the technical field of measuring rulers, in particular to a measuring ruler used for measuring rail wear. Background Art

[0002] Rail wear refers to the gradual wear of the rail head due to friction between the wheels and rails during operation. Rail wear typically occurs on the top surface of the rail and the inner side surfaces of the two rails where they meet, i.e., vertical wear and lateral wear. Rail wear can increase noise, vibration, and energy loss during vehicle operation. Therefore, to ensure safe operation, regular rail wear testing is necessary so that timely countermeasures can be taken when wear is excessive.

[0003] At present, when inspectors detect rail wear, the commonly used detection tool is the rail wear side wear ruler. The rail wear side wear ruler includes a vertical wear ruler, a side wear ruler and a magnetic positioning block. Both the vertical wear ruler and the side wear ruler are equipped with a digital display device. When measuring, the side wear ruler is first positioned on the side of the rail head of the measured rail through the magnetic positioning block, and then the vertical wear ruler and the side wear ruler are pushed so that the measuring heads of the two are in contact with the corresponding positions on the top surface and the inner side surface of the rail respectively, and the data on the digital display device is recorded.

[0004] However, the traditional rail wear measuring ruler has a strong magnet fixed under the handle, and the handle is adsorbed on the side of the rail head by two strong magnets. When the rail is used for a long time, the side of the rail head will rust, and the rust, iron slag, etc. will affect the close adhesion between the measuring ruler and the rail head, resulting in the measuring ruler not being firmly adsorbed, poor stability, easy to shake during measurement, difficult to operate and large errors in the measurement results. Utility Model Content

[0005] The purpose of the utility model is to provide a measuring ruler for measuring rail wear, aiming at the problem that a conventional rail wear measuring ruler in the background art is adsorbed on the side of the rail head by a magnet, and the side of the rail head is easily corroded when the rail is used for a long time, and the rust and iron slag affect the close adhesion between the measuring ruler and the rail head, resulting in the measuring ruler being loosely adsorbed, having poor stability, being easy to shake during measurement, being difficult to operate and having large errors in the measurement results.

[0008] The measuring ruler for measuring rail wear described in the present application includes a vertical grinding ruler, a side grinding ruler and a curved base frame. The vertical grinding ruler and the side grinding ruler are arranged above the curved base frame. The curved base frame includes a plurality of longitudinally arranged curved rods. The curved rods are used to be installed on the rail, and the curved rods can be adsorbed on the top surface of the rail, so that the curved base frame is installed on the top surface of the rail, and then the measuring ruler of the present application is installed on the rail, avoiding the use of a fixing method in which the measuring ruler is adsorbed on the side surface of the rail head, thereby avoiding the influence of rust on the side surface of the rail head on the stability of the traditional measuring ruler. Furthermore, the present application changes the traditional method of adsorbing the measuring ruler on the side surface of the rail head to a method of adsorbing the measuring ruler on the top surface of the rail by the curved rods through the arrangement of curved rods, changing the traditional point bonding to surface bonding, thereby increasing the contact surface between the measuring ruler of the present application and the rail, effectively avoiding the fat edge of the rail, and making the contact surface between the measuring ruler of the present application and the rail unaffected by the wear and deformation of the rail head, thereby making the adsorption of the measuring ruler of the present application and the rail more stable, thereby ensuring measurement accuracy.

[0009] Preferably, the arc-shaped rod comprises a horizontal rod, and a magnetic member is installed on a side of the horizontal rod close to the rail.

[0010] Preferably, a plurality of the arc-shaped rods are arranged at intervals in the longitudinal direction.

[0015] Preferably, it further comprises a second transverse movement frame which is slidably arranged, and the second transverse movement frame can drive the vertical grinding ruler to move transversely.

[0016] Preferably, the machine further comprises a second vertical frame, wherein the second vertical frame is connected to the second transverse frame, the vertical grinding ruler is installed in the second vertical frame, and the vertical grinding ruler can move vertically in the second vertical frame.

[0017] Preferably, a tip portion is horizontally provided at one end of the side grinding ruler close to the arc-shaped base.

[0037] Example 1

[0038] like Figure 1-Figure 5 As shown, this embodiment discloses a measuring ruler for measuring rail wear, comprising a vertical grinding ruler 2, a side grinding ruler 3 and an arc-shaped base frame 4, wherein the vertical grinding ruler 2 and the side grinding ruler 3 are arranged above the arc-shaped base frame 4;

[0039] The arc-shaped base frame 4 includes a plurality of longitudinally arranged arc-shaped rods 41 . The arc-shaped rods 41 are used to be installed on the rails 40 , and the arc-shaped rods 41 can be adsorbed on the top surface of the rails 40 .

[0040] The curved base frame 4 includes a curved rod 41. When in use, the curved rod 41 is mounted on the rail 40, and the curved rod 41 is adsorbed on the top surface of the rail 40, thereby installing the curved base frame 4 on the top surface of the rail 40, and then installing the measuring ruler of this embodiment on the rail 40, avoiding the use of a traditional fixing method of adsorbing the measuring ruler on the side of the rail head of the rail 40, thereby avoiding the influence of rust on the side of the rail head of the rail 40 on the stability of the measuring ruler. Furthermore, this embodiment changes the traditional method of adsorbing the measuring ruler on the side of the rail head of the rail 40 to a method of adsorbing the measuring ruler on the top surface of the rail 40 by providing the curved rod 41, changing the traditional method of adsorbing the measuring ruler on the side of the rail head of the rail 40 to a method of adsorbing the measuring ruler on the top surface of the rail 40 by the curved rod 41, changing the traditional point fitting to surface fitting, thereby increasing the contact surface between the measuring ruler of this embodiment and the rail 40, effectively avoiding the fat edge of the rail 40, and the contact surface between the measuring ruler of this embodiment and the rail is not affected by the wear and deformation of the rail head of the rail 40, ensuring that the measuring ruler of this embodiment and the rail 40 are more firmly adsorbed, thereby ensuring measurement accuracy.

[0041] In the present application, the arc rod 41 is adsorbed on the top surface of the rail 40, that is, the arc rod 41 is adsorbed on the top surface of the rail head of the rail 40, avoiding the use of a traditional fixing method of adsorbing the measuring ruler on the side of the rail head, thereby avoiding the impact of rust on the side of the rail head on the stability of the measuring ruler.

[0042] The components of a steel rail include the rail head, rail waist and rail bottom. The rail head contacts the train wheels, and the rail bottom is installed on the sleeper. Its function is to guide the operation of the train, withstand the huge pressure of the wheels and transfer it to the sleeper.

[0043] In one or more embodiments, Figure 5 As shown, the arc rod 41 includes a horizontal rod 411, and a magnetic member 30 is installed on the side of the horizontal rod 411 close to the rail 40. The magnetic member 30 is adsorbed on the surface of the rail 40, so that the arc rod 41 can be adsorbed on the rail;

[0044] like Figure 5 As shown, inclined rods 412 are connected to both ends of the horizontal rod 411. The inclined rods 412 are inclined outward. The two inclined rods 412 and the horizontal rod 411 form an open shape, which facilitates the convenient installation of the arc rod 41 on the rail 40 when in use.

[0045] In an optional embodiment, the magnetic member 30 is a strong magnet, such as a neodymium iron boron magnet, an aluminum nickel cobalt magnet, or the like.

[0046] In an optional embodiment, the curved base 4 includes a plurality of curved rods 41, with multiple curved rods 41 spaced longitudinally apart. By providing multiple curved rods 41, when in use, the plurality of curved rods 41 are all mounted on the rail 40, further increasing the contact area between the curved base 4 and the rail 40. This allows the curved base 4 to be more firmly adsorbed on the rail 40, thereby further ensuring that the measuring ruler of the present application is more firmly mounted on the rail 40, ensuring that the measuring ruler is stable and reliable during measurement.

[0047] Furthermore, if Figure 5 As shown, adjacent arc-shaped rods 41 are connected by connecting rods 42 .

[0048] The longitudinal direction mentioned in this embodiment refers to the length direction of the rail 40 .

[0049] In one or more embodiments, Figure 1 As shown, it also includes a crossbar 1, which is connected to the top of the arc-shaped base frame 4 through a telescopic rod 5;

[0050] The vertical grinding ruler 2 and the side grinding ruler 3 can move laterally on the crossbar 1 .

[0051] Since the vertical grinding ruler 2 and the side grinding ruler 3 can be moved laterally on the crossbar 1, it is convenient to adjust the positions of the vertical grinding ruler 2 and the side grinding ruler 3 during use to adapt to measurement at multiple positions;

[0052] Among them, such as Figures 1-4 As shown, it also includes a first transverse frame 6 slidably arranged on the crossbar 1, and the first transverse frame 6 can drive the side grinding ruler 3 to move transversely. The first transverse frame 6 drives the side grinding ruler 3 to move transversely, thereby realizing the transverse movement of the side grinding ruler 3 on the crossbar 1.

[0053] Further, if Figure 1 、 Figure 3 As shown, it also includes a first vertical frame 8 , which is connected to the first transverse frame 6 . The side grinding ruler 3 is installed in the first vertical frame 8 , and the side grinding ruler 3 can move vertically in the first vertical frame 8 .

[0054] The first vertical frame 8 is connected to the side of the first transverse frame 6 away from the crossbar 1. The first vertical frame 8 is vertically arranged. The side grinding ruler 3 is vertically installed on the first vertical frame 8. Since the side grinding ruler 3 can move vertically in the first vertical frame 8, Figure 6 As shown, when a guard rail 50 is provided next to the rail 40, the side wear ruler 3 of a conventional rail wear measuring ruler is difficult to extend between the rail 40 and the guard rail 50 to measure the rail 40 due to the small spacing between the rail 40 and the guard rail 50. A conventional rail wear measuring ruler, such as the adjustable integrated measuring tool for rail wear detection disclosed in Patent No. CN219103880U, has a horizontal measuring ruler equivalent to a side wear ruler.

[0055] In this embodiment, since the side grinding ruler 3 can be moved laterally on the crossbar 1 through the first transverse frame 6, and the side grinding ruler 3 can be moved vertically on the first vertical frame 8, Figure 6 As shown, when a guard rail 50 is provided next to the rail 40, the side grinding ruler 3 is first moved vertically upward in the first vertical frame 8, and then the first transverse frame 6 is moved to move the side grinding ruler 3 to the side of the rail 40, and then the side grinding ruler 3 is moved vertically downward in the first vertical frame 8. When the measuring end of the side grinding ruler 3 is flush with the side of the rail 40, the first transverse frame 6 is moved again to make the side grinding ruler 3 approach and abut against the side of the rail 40, so as to perform measurement. The measuring ruler of this embodiment can place the side grinding ruler 3 into the gap between the guard rail 50 and the rail 40, so as to meet the measurement of various line conditions. There is no need to remove the guard rail 50, which can save 2-3 cooperating personnel.

[0056] In an optional embodiment, if Figure 3 As shown, the first transverse moving frame 6 is a channel-shaped component, and the cross bar 1 is slidably arranged inside the groove of the first transverse moving frame 6, so that the first transverse moving frame 6 can slide on the cross bar 1.

[0057] In an optional embodiment, if Figure 1As shown, the first vertical frame 8 is a groove-shaped member, and the side grinding ruler 3 is slidably arranged inside the groove of the first vertical frame 8 , so that the side grinding ruler 3 can move in the first vertical frame 8 .

[0058] In an optional embodiment, if Figure 1 As shown, a tip portion 31 is horizontally provided at one end of the side grinding ruler 3 close to the arc-shaped base 4 . The tip portion 31 is the measuring end of the side grinding ruler 3 and is used to measure the side wear of the rail 40 .

[0059] In one or more embodiments, Figure 1 As shown, the second transverse moving frame 7 is also provided on the cross bar 1, and the second transverse moving frame 7 can drive the vertical grinding ruler 2 to move transversely. The second transverse moving frame 7 drives the vertical grinding ruler 2 to move transversely, thereby realizing the transverse movement of the vertical grinding ruler 2 on the cross bar 1.

[0060] In an optional embodiment, if Figure 1 、 Figure 2 As shown, it also includes a second vertical frame 9, which is connected to the second transverse frame 7. The vertical grinding ruler 2 is installed in the second vertical frame 9. The vertical grinding ruler 2 can move vertically in the second vertical frame 9 to adjust the vertical height of the vertical grinding ruler 2.

[0061] In an optional embodiment, if Figure 2 As shown, the second transverse frame 7 is a channel-shaped component, and the cross bar 1 is slidably arranged inside the groove of the second transverse frame 7, so that the second transverse frame 7 can slide on the cross bar 1.

[0062] In an optional embodiment, if Figure 1 As shown, the second vertical frame 9 is a groove-shaped member, and the vertical grinding ruler 2 is slidably arranged inside the groove of the second vertical frame 9 , so that the vertical grinding ruler 2 can move in the second vertical frame 9 .

[0063] In an optional embodiment, if Figures 1-4 As shown, the telescopic rod 5 includes a rod barrel and a round rod, and part of the round rod is slidably arranged in the rod barrel. When in use, the end of the round rod away from the rod barrel is fixed to the arc-shaped base frame 4, and the rod barrel is fixed on the cross bar 1. By moving the rod barrel upward, the entire telescopic rod 5 is extended, and by moving the rod barrel downward, the entire telescopic rod 5 is shortened; further, a locking nut is installed on the rod barrel, one end of the locking nut passes through the rod barrel and abuts against the round rod, and by tightening the locking nut, the round rod is fixed to the rod barrel, thereby fixing the position of the rod barrel and the round rod.

[0064] Example 2

[0065] like Figure 1 As shown, based on Example 1, the measuring ruler for rail wear measurement described in this embodiment further includes a first digital display 10 and a second digital display 20;

[0066] The first digital display 10 is mounted on the second vertical frame 9, and the second vertical frame 9 is used to measure the vertical displacement value of the vertical grinding ruler 2;

[0067] The second digital display 20 is installed on the first transverse movement frame 6 , and is used to measure the transverse displacement value of the side grinding ruler 3 .

[0068] The first digital display 10 is used to measure the vertical displacement value of the vertical grinding ruler 2. When the vertical grinding ruler 2 measures the top surface of the rail 40, the value measured by the vertical grinding ruler 2 is read through the first digital display 10. The first digital display 10 is provided with a first on / off key 101, a first return to zero key 102, and a first unit conversion key 103.

[0069] The second digital display 20 is used to measure the lateral displacement value of the side grinding ruler 3. When the side grinding ruler measures the side of the rail 40, the value measured by the side grinding ruler 3 is read through the second digital display 20. The second digital display 20 is provided with a second on / off key 201, a second return to zero key 202 and a second unit conversion key 203.

[0070] This embodiment also discloses a method for using the measuring ruler of this embodiment, which includes the following steps:

[0071] Step 1: Perform reference zero calibration on the side grinding ruler 3 on the standard rail. Place the side grinding ruler 3 close to 16 mm from the rail head of the rail 40, and place the vertical grinding ruler 2 close to 1 / 3 of the effective edge of the top surface of the rail 40. Adjust the second zeroing key 202 to perform reference zero calibration. Align the zero scale value on the side grinding ruler 3 with the reference zero point of the second digital display 20. Press the second zeroing key 202. The reference zero point of the side grinding ruler 3 is now adjusted.

[0072] Step 2: Place the side grinding ruler 3 on the five major pile point marks of the rail 40, press the side grinding ruler 3 and the vertical grinding ruler 2 together, and read the measurement value.

[0073] In this application, the side wear ruler 3 is hung vertically on the cross bar 1, and the second digital display 20 is installed on the cross bar 1. The side wear of the rail 40 can be measured by slightly sliding the side wear ruler 3, which meets the requirements of rail 40 wear detection for various types of track lines, with easy operation, high efficiency and accuracy.
