[0031] Please refer to Figure 1In one embodiment, the rail wear detection device includes a horizontal measuring piece 100, a clamping assembly 200 and at least three vertical measuring assemblies 300. The clamping assemblies 200 are arranged at both ends of the horizontal measuring piece 100 along the first direction and are used to clamp and fix to the rails and / or frogs. At least three vertical measuring assemblies 300 are arranged on the horizontal measuring piece 100 and are used to measure the vertical wear of the rails and / or frogs; wherein, each vertical measuring assembly 300 is detachably arranged on the horizontal measuring piece 100, and the position of each vertical measuring assembly 300 in the first direction is adjustable, and the first direction is the length direction of the rail wear detection device.

[0032] It should be noted that the first direction is Figure 1 The X direction shown is the length direction of the rail wear detection device, that is, the horizontal direction.

[0033] Here, because each vertical measurement assembly 300 is detachably mounted on the horizontal measurement member 100, the number of vertical measurement assemblies 300 can be adjusted based on actual measurement needs. For example, when measuring the vertical wear of a rail, the two sides of the clamping assembly 200 are clamped and fixed to the rail. In this case, only one vertical measurement assembly 300 is required to detect the vertical wear of the rail, and the other vertical measurement assemblies 300 can be removed from the horizontal measurement member 100. For another example, when measuring the vertical wear of a frog, the frog includes a center rail 10 and wing rails 20 located on either side of the center rail 10. The two sides of the clamping assembly 200 are clamped and fixed to the two wing rails 20. In this case, three vertical measurement assemblies 300 are required to respectively detect the vertical wear of the center rail 10 and the two wing rails 20. Three vertical measurement assemblies 300 can be installed and their positions on the horizontal measurement member 100 can be adjusted.

[0034] In the above-mentioned rail wear measuring device, at least three vertical measuring components 300 are detachably arranged on the horizontal measuring part 100, and the position of each vertical measuring component 300 on the horizontal measuring part 100 is adjustable. The number and position of the vertical measuring components 300 can be adjusted according to actual measurement needs. The same device can simultaneously meet the measurement needs of the vertical wear of the rails or switch, and can intuitively and comprehensively detect the wear of the rails or switch without the need to be equipped with a variety of inspection devices. It has a wide range of applications and high measurement flexibility, which is conducive to cost savings.

[0035] In an embodiment of the present application, the horizontal measuring member 100 is a horizontal measuring ruler, and a scale is provided on the horizontal measuring ruler, which can facilitate intuitive adjustment of the horizontal position of the vertical measuring component 300.

[0036] In the embodiment of the present application, the clamping assembly 200 is a component used to clamp and fix to the rail and / or frog. The clamping assembly 200 can adopt various structures. For example, the clamping assembly 200 includes two clamping seats, each clamping to the two sides of the rail or the two sides of the frog. The two clamping seats are provided on the leveling member 100, and the horizontal spacing between the two clamping seats can be adjusted according to actual measurement requirements.

[0037] In the embodiments of the present application, the vertical measurement assembly 300 is a component used to measure the vertical wear of a rail and / or frog. The vertical measurement assembly 300 can adopt various structures. For example, the vertical measurement assembly 300 can include a vertical measuring ruler. The vertical wear of the rail and / or frog is measured using the vertical measuring ruler. The number and position of the vertical measurement assemblies 300 can be adjusted according to actual measurement requirements.

[0038] Specifically, please refer to Figure 2 Each vertical measuring assembly 300 includes a movable body 310 and a vertical measuring piece 320. The vertical measuring piece 320 is fixed to the movable body 310 and is used to measure the vertical wear of the rail and / or the switch. The movable body 310 is detachably mounted on the horizontal measuring piece 100 and its position in the first direction is adjustable.

[0039] The beneficial effects here are: the movable body 310 is arranged on the horizontal measuring piece 100, and the movable body 310 can move along the first direction on the horizontal measuring piece 100, and drive the vertical measuring piece 320 to move along the first direction, thereby changing the position of the vertical measuring piece 320 in the first direction, so that the vertical measuring piece 320 can be aligned with the horizontal position of the rail and / or the switch, which is convenient for the subsequent measurement of the vertical wear amount.

[0040] In the embodiment of the present application, the movable body 310 is a component detachably provided on the level measuring member 100, and the movable body 310 and the level measuring member 100 can be detachably connected in various ways. For example, the movable body 310 and the level measuring member 100 can be connected by plugging or snapping.

[0041] In the embodiment of the present application, the vertical measuring member 320 is a component fixed to the movable body 310 and used to measure the vertical wear of the rail and / or frog. The vertical measuring member 320 and the movable body 310 can be fixed in various ways. For example, the vertical measuring member 320 and the movable body 310 can be fixed by fasteners such as screws or bolts, or the vertical measuring member 320 and the movable body 310 can be fixed by a snap connection or plug connection.

[0042] For details about this embodiment, please refer to Figure 3 and Figure 4The movable body 310 is provided with a slide groove 310a extending along the first direction, and the horizontal measuring member 100 is inserted into the slide groove 310a so that the movable body 310 can slide along the first direction relative to the horizontal measuring member 100.

[0043] It is understandable that when the horizontal position of the movable body 310 needs to be adjusted, the movable body 310 is moved along the first direction. At this time, the slide groove 310a slides along the first direction relative to the horizontal measuring member 100, thereby changing the horizontal position of the movable body 310.

[0044] The beneficial effect here is that the slide groove 310a of the movable body 310 can slide along the first direction relative to the horizontal measuring member 100, so that the position adjustment of the movable body 310 in the first direction is convenient and flexible, which is conducive to improving the adjustment efficiency.

[0045] In the embodiment of the present application, the chute 310a is a through-groove extending from left to right along the first direction through the movable body 310. That is, both ends of the chute 310a in the first direction are open, so that the level measuring member 100 can be inserted into the chute 310a from either open end. Since the cross-section of the level measuring member 100 is rectangular, the cross-section of the chute 310a is correspondingly rectangular. In other embodiments, the cross-section of the level measuring member 100 can also be circular or have other shapes, and the cross-section of the chute 310a can also be circular or have other shapes.

[0046] In an embodiment of the present application, the cross-sectional dimension of the slide groove 310a is greater than or equal to the cross-sectional dimension of the level measuring member 100, so that the level measuring member 100 can be smoothly inserted into the slide groove 310a.

[0047] For details about this embodiment, please refer to Figure 3 and Figure 4 The horizontal measuring member 100 is provided with a zero point L1, and the surface of the movable body 310 is provided with an alignment scale L2 for aligning with the zero point.

[0048] It should be noted that when measuring the vertical wear of a rail or a switch, the movable body 310 is first slid on the horizontal measuring piece 100, and whether the movable body 310 has slid to the desired position is determined based on whether the alignment zero point L1 and the alignment scale L2 are aligned. When the alignment zero point L1 and the alignment scale L2 are aligned, the movable body 310 slides to the desired position, and at this time, the position of the movable body 310 on the horizontal measuring piece 100 does not need to be adjusted further.

[0049] The beneficial effect here is: by judging whether the movable body 310 has slid to the required position based on whether the alignment zero point L1 and the alignment scale L2 are aligned, it is convenient for subsequent intuitive and comprehensive detection of the wear of the rail or the switch, which is conducive to improving the detection efficiency.

[0050] In an embodiment of the present application, the alignment zero point L1 can be set at only one horizontal position, or at least two horizontal positions. For example, when the number of vertical measurement components 300 is three, three alignment zero points L1 can be set to facilitate quick judgment and adjustment of the horizontal positions of the three vertical measurement components 300.

[0051] In an embodiment of the present application, the alignment scale L2 is provided on the surface of the movable body 310, and the alignment scale L2 and the alignment zero point L1 are located on the same side. The alignment scale L2 can be integrally formed on the surface of the movable body 310 (for example, engraved) or adhered to the surface of the movable body 310.

[0052] Please refer to Figure 3 and Figure 4 The movable body 310 includes a first main body portion 311, a vertical portion 312 and a second main body portion 313. The second main body portion 313 and the first main body portion 311 are arranged at both ends of the vertical portion 312 along the second direction. The second main body portion 313, the vertical portion 312 and the first main body portion 311 are arranged to form a slide groove 310a. The slide groove 310a has an opening on one side along the third direction to expose the scale of the horizontal measuring piece 100. The third direction, the second direction and the first direction intersect with each other and are not coplanar.

[0053] It should be noted that the second direction is Figure 3 and Figure 4 The Y direction shown is the height direction of the rail wear detection device, that is, the vertical direction; the third direction is Figure 3 and Figure 4 The Z direction shown is the thickness direction of the rail wear detection device.

[0054] The beneficial effects here are: the second main body 313, the vertical part 312 and the first main body 311 are arranged to form a slide groove 310a, and the slide groove 310a has an opening on one side along the third direction, which enables the horizontal measuring piece 100 to pass through the slide groove 310a. At the same time, the movable main body 310 does not block the scale on the horizontal measuring piece 100, and will not hinder the intuitive reading of the scale value on the horizontal measuring piece 100.

[0055] In an embodiment of the present application, the second main body portion 313 and the first main body portion 311 are arranged at both ends of the vertical portion 312 along the second direction. The second main body portion 313, the first main body portion 311 and the vertical portion 312 can be an integrated structure. For example, the second main body portion 313, the first main body portion 311 and the vertical portion 312 are integrally formed by injection molding, casting, etc.; the second main body portion 313, the first main body portion 311 and the vertical portion 312 can also be a split structure. For example, the second main body portion 313, the first main body portion 311 and the vertical portion 312 are fixed by clamping, riveting, etc.

[0056] In the embodiment of the present application, the first main body 311 is located at the upper end of the vertical portion 312 in the vertical direction, and the second main body 313 is located at the lower end of the vertical portion 312 in the vertical direction. The shapes of the first main body 311 and the second main body 313 can be the same or different. The vertical portion 312 can be a rectangular plate structure, a circular plate structure, or a structure of other shapes.

[0057] Specifically, please refer to Figure 1 The second main body portion 313 and / or the first main body portion 311 are constructed as a hook-shaped structure, and the hook-shaped structure can be hung on the horizontal measuring member 100.

[0058] It can be understood that the second main body portion 313 and / or the first main body portion 311 are constructed as a hook-type structure, which can be hung on the horizontal measuring member 100. When the movable body 310 slides relative to the horizontal measuring member 100, the movable body 310 will not separate from the horizontal measuring member 100.

[0059] The beneficial effect here is that the horizontal measuring member 100 can be passed through the slide groove 310a of the movable body 310, and the movable body 310 is hung on the horizontal measuring member 100. When the movable body 310 slides relative to the horizontal measuring member 100, the movable body 310 will not separate from the horizontal measuring member 100.

[0060] In an embodiment of the present application, the second main body portion 313 and / or the first main body portion 311 are constructed as a hook-shaped structure, that is, only the second main body portion 313 can be a hook-shaped structure, or only the first main body portion 311 can be a hook-shaped structure, or both the second main body portion 313 and the first main body portion 311 can be hook-shaped structures.

[0061] In an embodiment of the present application, the hook-shaped structure is a structure having at least one bending portion, and the bending portion can be hung on the horizontal measuring member 100, wherein the bending portion can be L-shaped, C-shaped or other shapes.

[0062] For further information, please refer to Figure 3 and Figure 4 The vertical measurement assembly 300 further includes a vertical positioning member. The first main body portion 311 is provided with a first positioning hole 311a along the second direction. The vertical positioning member is screwed to the first positioning hole 311a for positioning the movable body 310 in the second direction.

[0063] It can be understood that when measuring the vertical wear of the rail or the switch, the movable body 310 is first slid on the horizontal measuring piece 100, and whether the movable body 310 has slid to the desired position is determined based on whether the alignment zero point and the alignment scale are aligned. When the alignment zero point and the alignment scale are aligned, the movable body 310 slides to the desired position. At this time, the position of the movable body 310 on the horizontal measuring piece 100 does not need to be adjusted anymore, and the movable body 310 is screwed to the first positioning hole 311a through the vertical positioning piece to position the movable body 310 in the second direction.

[0064] The beneficial effect here is that when the position of the movable body 310 on the horizontal measuring member 100 does not need to be further adjusted, the vertical positioning member is screwed to the first positioning hole 311a to position the movable body 310 in the second direction, which is convenient for subsequent measurement of vertical wear.

[0065] In the embodiment of the present application, the vertical positioning member is a screw or a stud, and the first positioning hole 311a is a screw hole. In other embodiments, the vertical positioning member can also be other types of positioning parts, and the first positioning hole 311a can also be other types of holes.

[0066] In the embodiment of the present application, the number of vertical positioning members is not limited to one. When the number of vertical positioning members is at least two, the number of first positioning holes 311a is also at least two, and the first positioning holes 311a are arranged in a one-to-one correspondence with the vertical positioning members.

[0067] For further information, please refer to Figure 3 and Figure 4 The vertical measurement assembly 300 further includes a horizontal positioning member. The vertical portion 312 is provided with a second positioning hole 312a along the third direction. The horizontal positioning member is screwed to the second positioning hole 312a for positioning the movable body 310 in the third direction.

[0068] It can be understood that when measuring the vertical wear of the rail or the switch, the movable body 310 is first slid on the horizontal measuring piece 100, and whether the movable body 310 has slid to the desired position is determined based on whether the alignment zero point and the alignment scale are aligned. When the alignment zero point and the alignment scale are aligned, the movable body 310 slides to the desired position. At this time, the position of the movable body 310 on the horizontal measuring piece 100 does not need to be adjusted further. The vertical positioning piece is screwed to the first positioning hole 311a for positioning the movable body 310 in the second direction, and the horizontal positioning piece is screwed to the second positioning hole 312a for positioning the movable body 310 in the third direction.

[0069] The beneficial effect here is: when the position of the movable body 310 on the horizontal measuring piece 100 does not need to be adjusted any further, the vertical positioning piece is screwed to the first positioning hole 311a to position the movable body 310 in the second direction, and the horizontal positioning piece is screwed to the second positioning hole 312a to position the movable body 310 in the third direction, which facilitates the subsequent measurement of vertical wear.

[0070] In the embodiment of the present application, the horizontal positioning member is a screw or a stud, and the second positioning hole 312a is a screw hole. In other embodiments, the horizontal positioning member can also be other types of positioning parts, and the second positioning hole 312a can also be other types of holes.

[0071] In the embodiment of the present application, the number of horizontal positioning members is not limited to one. When the number of horizontal positioning members is at least two, the number of second positioning holes 312a is also at least two, and the second positioning holes 312a are arranged in a one-to-one correspondence with the horizontal positioning members.

[0072] For details about this embodiment, please refer to Figure 1 The vertical measuring member 320 and / or the horizontal measuring member 100 are digital measuring rulers.

[0073] The beneficial effect here is that the vertical measuring member 320 and / or the horizontal measuring member 100 is a digital measuring ruler, which can quickly read the horizontal position of the movable body 310 and the vertical wear of the rail or the switch, and can effectively improve the measurement efficiency.

[0074] In an embodiment of the present application, the vertical measuring member 320 is a digital dial indicator, which can be extended and retracted in the vertical direction to contact the rail or the frog to quickly obtain the vertical wear of the rail or the frog.

[0075] Please refer to Figure 1 The holding assembly 200 includes a first holder 210 and a second holder 220. The first holder 210 and the second holder 220 are arranged at both ends of the horizontal measuring member 100 along the first direction. The first holder 210 and / or the second holder 220 can move along the first direction.

[0076] It should be noted that the first card holder 210 and / or the second card holder 220 can move along the first direction, that is, the distance between the first card holder 210 and the second card holder 220 in the first direction is adjustable. For example, when measuring the vertical wear of a rail, the first clamp 210 and the second clamp 220 are respectively clamped and fixed on both sides of the rail. When the size or type of the rail changes, the first clamp 210 and / or the second clamp 220 are moved along the first direction to adjust the distance between the first clamp 210 and the second clamp 220 in the first direction, so that the first clamp 210 and the second clamp 220 are adapted to rails of different types or sizes. For another example, when measuring the vertical wear of a frog, the frog includes a heart rail 10 and wing rails 20 located on both sides of the heart rail 10. The two sides of the clamping assembly 200 are respectively clamped and fixed to the two wing rails 20. The first clamp 210 and / or the second clamp 220 are moved along the first direction to adjust the distance between the first clamp 210 and the second clamp 220 in the first direction, so that the first clamp 210 and the second clamp 220 are adapted to the frog.

[0077] The beneficial effect here is that the first clamping seat 210 and / or the second clamping seat 220 can move along the first direction, that is, the spacing between the first clamping seat 210 and the second clamping seat 220 in the first direction is adjustable, so that the clamping assembly 200 can adapt to rails or switches of different types or sizes, thereby improving the applicability of the clamping assembly 200.

[0078] In an embodiment of the present application, the first card holder 210 and / or the second card holder 220 can move along the first direction, that is: the first card holder 210 is fixed and the second card holder 220 can move along the first direction; or, the first card holder 210 can move along the first direction and the second card holder 220 is fixed; or, both the first card holder 210 and the second card holder 220 can move along the first direction.

[0079] In an embodiment of the present application, the bottoms of the first clamping seat 210 and the second clamping seat 220 are both hook-shaped structures, and the hook-shaped structure is a structure having at least one bending portion, which can be clamped on the rail or the switch, wherein the bending portion can be L-shaped, C-shaped or other shapes.

[0080] The technical features of the above-mentioned embodiments can be combined arbitrarily.
