DETAILED DESCRIPTION

[0030] A detection vehicle in the related art, referring to Figure 1 , comprising: a detection unit 100; a limiting wheel 200 connected with the detection unit 100; a traveling wheel 300 connected with the detection unit 100. The limiting wheel 200 is used to abut against the inner side of a to-be-detected rail a', and the traveling wheel 300 is used to contact the upper rail surface of the to-be-detected rail a'. The two limiting wheels 200 include a front limiting wheel and a rear limiting wheel, and the front limiting wheel and the rear limiting wheel are arranged along the length direction of the to-be-detected rail a'. The detection unit 100 includes a profile detection assembly capable of detecting the profile of the to-be-detected rail a'.

[0031] When the detection vehicle travels in the traveling direction on a region where the track gauge of the to-be-detected rail a' has an offset, a "snake-like" motion of the detection vehicle is caused, the limiting wheel 200 is easy to be separated from the inner side of the to-be-detected rail a', which causes the detection point of the profile detection assembly to deviate from the center line of the to-be-detected rail a' by a preset distance, and further causes the accuracy of the detection data obtained by the profile detection assembly to be reduced.

[0032] Based on this, this application provides a benchmark adaptive device, a detection device, and an intelligent polishing system, which improves the accuracy of the detection data.

[0033] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or part referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0036] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0037] One embodiment of this utility model proposes a reference adaptive device W, combined with... Figure 2 and Figure 3 As shown, it includes:

[0038] The first connecting plate unit 1 and the second connecting plate 2 are arranged opposite to each other and at intervals.

[0039] The swing member 3 is connected to the first connecting plate unit 1 and the second connecting plate 2, and is used to make the first connecting plate unit 1 rotate relative to the second connecting plate 2 in a plane parallel to the plane opposite to the first connecting plate unit 2 and the second connecting plate 2.

[0040] The first damping component 4 is connected to the first connecting plate unit 1 and the second connecting plate 2, and is used to deform in a plane parallel to the first connecting plate unit 1 and the second connecting plate 2.

[0041] The second damping assembly 5 is connected with the first connecting plate unit 1 and also used to connect with the detection vehicle b, and the deformation direction of the second damping assembly 5 has a component in the direction perpendicular to the walking direction of the detection vehicle b and parallel to the second connecting plate 2.

[0042] When the detection vehicle b walks in the walking direction in the region where the track gauge of the to-be-detected track a has an offset, the reference self-adaptive device W of the embodiment makes the detection vehicle b abut against the side wall of the to-be-detected track a by deforming the second damping assembly 5 in the direction perpendicular to the walking direction of the detection vehicle b and parallel to the second connecting plate 2, so as to avoid the detection vehicle b from being separated from the to-be-detected track a. At the same time, when the detection vehicle b walks in the walking direction in the region where the track gauge of the to-be-detected track a has an offset, the front end and the rear end of the detection vehicle b rotate and swing relative to the walking direction of the detection vehicle b, the swing member 3 swings with the actual curve curvature of the region where the to-be-detected track a has an offset, and then the first connecting plate unit 1 rotates relative to the second connecting plate 2 in the plane parallel to the relative plane of the first connecting plate unit 2 and the second connecting plate 2. The relative rotation of the first connecting plate unit 1 relative to the second connecting plate 2 makes the first damping assembly 4 compress and store a part of energy in the plane parallel to the relative plane of the first connecting plate unit 1 and the second connecting plate 2. Then, the first damping assembly 4 releases the part of energy, so that the first connecting plate unit 1 reversely rotates relative to the second connecting plate 2 in the plane parallel to the relative plane of the first connecting plate unit 2 and the second connecting plate 2, and then the detection vehicle b smoothly drives away from the region where the track gauge of the to-be-detected track a has an offset. The stability of the detection reference of the profile detection of the to-be-detected track a by the detection vehicle b is ensured, and the accuracy of the data of the profile detection is improved.

[0043] In one embodiment, in combination with Figure 2 and Figure 3 The first damping assembly 4 includes a first shaft 41, a first elastic member 42 and a first moving member 43. The two ends of the first shaft 41 are fixedly connected with the side surface of the second connecting plate 2 facing the first connecting plate unit 1. The first elastic member 42 is sleeved on the side wall of the first shaft 41, and has opposite first and second ends and a third end between the first and second ends in the deformation direction of the first elastic member 42. The first moving member 43 is connected with the third end and fixedly connected with the side surface of the first connecting plate unit 1 facing the second connecting plate 2. The first elastic member 42 can be a spring.

[0044] The first shaft 41 is used to support the first elastic member 42, and ensures that the third end of the first elastic member 42 deforms along the first shaft 41 when the first elastic member 42 is subjected to the force of the first moving member 43. When the distance between the first end and the third end decreases, that is, the first elastic member 42 between the first end and the third end is compressed, the distance between the third end and the second end increases, that is, the first elastic member 42 between the third end and the second end is stretched. When the distance between the first end and the third end increases, that is, the first elastic member 42 between the first end and the third end is stretched, the distance between the third end and the second end decreases, that is, the first elastic member 42 between the third end and the second end is compressed.

[0045] The first shaft 41 is arranged apart from the first connecting plate unit 1.

[0046] The first connecting plate unit 1 comprises the first connecting plate 11 and the third connecting plate 12, and the third connecting plate 12 is located between the first connecting plate 11 and the second connecting plate 2. The first moving member 43 is located on the side of the third connecting plate 12 facing the second connecting plate 2 and is fixedly connected to the surface of the side of the third connecting plate 12 facing the second connecting plate 2, and the first moving member 43 is arranged apart from the second connecting plate 2. The first connecting plate 11 does not rotate relative to the third connecting plate 12 in a plane parallel to the plane in which the first connecting plate 11 is opposite to the third connecting plate 12. The first connecting plate 11 is used to move relative to the third connecting plate 12 in a direction perpendicular to the first connecting plate 11 and the third connecting plate 12.

[0047] In one embodiment, as Figure 2 The first damping assembly 4 further comprises a first shaft seat 44, which is fixedly connected to the surface of the side of the second connecting plate 2 facing the first connecting plate unit 1; wherein the first end and the second end of the first shaft 41 are respectively fixedly connected to different first shaft seats 44. The first shaft seat 44 provides stable support for the first shaft 41.

[0048] In one embodiment, as Figure 2 The first damping assembly 4 further comprises a limiting member 45, which is respectively located on both sides of the first moving member 43 along the deformation direction of the first elastic member 41 and is fixedly connected to the surface of the side of the second connecting plate 2 facing the first connecting plate unit 1. The limiting member 45 limits the movement range of the first moving member 43, so that the relative rotation of the first connecting plate unit 1 and the second connecting plate 2 does not exceed the allowed range.

[0049] In one embodiment, as Figure 2 and Figure 3, the swing member 3 is a swing bearing; one of the inner ring and the outer ring of the swing bearing is fixedly connected with the side surface of the second connecting plate 2 facing the first connecting plate unit 1, and the other is fixedly connected with the side surface of the first connecting plate unit 1 facing the second connecting plate 2. The first connecting plate unit 1 can rotate relative to the second connecting plate 2 around the central axis of the swing bearing.

[0050] In one specific embodiment, the inner ring of the swing bearing is fixedly connected with the side surface of the second connecting plate 2 facing the first connecting plate unit 1, and is spaced apart from the side surface of the first connecting plate unit 1 facing the second connecting plate 2, and the outer ring of the swing bearing is fixedly connected with the side surface of the first connecting plate unit 1 facing the second connecting plate 2, and is spaced apart from the side surface of the second connecting plate 2 facing the first connecting plate unit 1. For example, the outer ring of the swing bearing is fixedly connected with the side surface of the third connecting plate 12 facing the second connecting plate 2.

[0051] In another specific embodiment, the outer ring of the swing bearing is fixedly connected with the side surface of the second connecting plate 2 facing the first connecting plate unit 1, and is spaced apart from the side surface of the first connecting plate unit 1 facing the second connecting plate 2, and the inner ring of the swing bearing is fixedly connected with the side surface of the first connecting plate unit 1 facing the second connecting plate 2, and is spaced apart from the side surface of the second connecting plate 2 facing the first connecting plate unit 1. For example, the inner ring of the swing bearing is fixedly connected with the side surface of the third connecting plate 12 facing the second connecting plate 2.

[0052] In one embodiment, as shown in Figure 2 , the second damping assembly 5 is located on the side of the first connecting plate unit 1 away from the second connecting plate 2.

[0053] In one embodiment, as shown in Figure 2 , the deformation direction of the second damping assembly 5 is perpendicular to the walking direction of the detection vehicle b and parallel to the second connecting plate 2. In this way, the second damping assembly 5 can better deform to make the detection vehicle b abut against the side wall of the to-be-detected track a.

[0054] In one embodiment, as shown in Figure 2 and Figure 3 , the second damping assembly 5 includes a second shaft 51, a second moving member 52, and a second elastic member 53. The second moving member 52 is sleeved on the side wall of the second shaft 51. The second elastic member 53 is sleeved on the side wall of the second shaft 51 and located on both sides of the second moving member 52. Among them, Figure 2 and Figure 3 , the two ends of the second shaft 51 are connected with the side surface of the first connecting plate unit 1 away from the second connecting plate 2, and the second moving member 52 is used for connecting with the detection vehicle b. In other embodiments, the two ends of the second shaft 51 are used for connecting with the detection vehicle b, and the second moving member 52 is connected with the side surface of the first connecting plate unit 1 away from the second connecting plate 2.

[0055] The second shaft 51 serves to support the second moving member 52 and the second elastic member 53, and allows the second moving member 52 and the second elastic member 53 to move along the second shaft 51.

[0056] Specifically, the second elastic member 53 can be a spring, and the second moving member 52 can be a slider.

[0057] The second elastic member 53 is located on both sides of the second moving member 52, and the second elastic members 53 on both sides of the second moving member 52 exert opposite forces on the second moving member 52. Through the movement of the second moving member 52 and the deformation of the second elastic members 53 on both sides of the second moving member 52, the detection vehicle b is tightly abutted against the side wall of one side of the to-be-detected track a, and the stable contact state of the detection vehicle b and the side wall of one side of the to-be-detected track a is maintained.

[0058] In one embodiment, as Figure 2 and Figure 3 The second damping assembly 5 further comprises a second shaft seat 54, which is fixedly connected with the side surface of the first connecting plate unit 1 away from the second connecting plate 2. Specifically, the second shaft seat 54 is fixedly connected with the side surface of the first connecting plate away from the second connecting plate 2, and the two ends of the second shaft 51 are fixedly connected with different second shaft seats 54. The two ends of the second shaft 51 are fixedly connected with the second shaft seats 54.

[0059] In one embodiment, as Figure 2 and Figure 3 The reference adaptive device W further comprises a third damping assembly 6, which is used to allow the first connecting plate 11 and the third connecting plate 12 to move relatively in a direction perpendicular to the first connecting plate 11 and the third connecting plate 12.

[0060] In one embodiment, as Figure 2 and Figure 3 The third damping assembly 6 comprises a third shaft 61 and a third elastic member 62. One end of the third shaft 61 is fixedly connected with the first connecting plate 11, the third shaft 61 passes through the third connecting plate 12 and is arranged in a spaced manner with the second connecting plate 2; the third elastic member 62 is located between the first connecting plate 11 and the third connecting plate 12 and is sleeved on the side wall of the third shaft 61.

[0061] Specifically, the third elastic member 62 can be a spring.

[0062] The third elastic member 62 can exert a downward force on the detection vehicle b through compression, so that the detection vehicle b and the upper track surface of the to-be-detected track a are always in close contact, and the relative position of the detection point of the detection vehicle b to the upper track surface of the to-be-detected track a is stable during the flatness detection of the to-be-detected track a by the detection vehicle b.

[0063] In one embodiment, with reference toFigure 2 and Figure 3 The third damping assembly 6 further comprises a follower bearing 63 fixedly connected with the third connecting plate 12, wherein the third shaft 61 passes through the follower bearing 63. The third elastic member 62 is located between the follower bearing 63 and the first connecting plate 11.

[0064] In one embodiment, the follower bearing 63 is fixedly connected with a side surface of the third connecting plate 12 facing the second connecting plate 2. The follower bearing 63 is spaced from the swing member 3. Illustratively, the follower bearing 63 is located around a side wall of the swing member 3 surrounding a central axis of the swing member 3.

[0065] In another embodiment, the follower bearing 63 is fixedly connected with a side surface of the third connecting plate 12 facing the first connecting plate 11.

[0066] Specifically, the follower bearing 63 can be a linear bearing.

[0067] The follower bearing 63 is fixedly connected with the third connecting plate 12 and allows the third shaft 61 to pass through, thereby stabilizing the position of the third shaft 61 in a plane parallel to the first connecting plate 11 and the third connecting plate 12.

[0068] In one embodiment, as Figure 2 The number of the third damping assemblies 6 is multiple. Illustratively, the number of the third damping assemblies 6 is four. In other embodiments, the number of the third damping assemblies 6 can be two, three, or an integer greater than four.

[0069] In one embodiment, the orthographic projection of the third shaft 61 on the first connecting plate 11 in a direction perpendicular to the first connecting plate 11 is spaced from the orthographic projection of the swing member 3 on the first connecting plate 11 in the direction perpendicular to the first connecting plate 11. When the number of the third damping assemblies 6 is multiple, the orthographic projections of the multiple third shafts 61 on the first connecting plate 11 in the direction perpendicular to the first connecting plate 11 surround the orthographic projection of the swing member 3 on the first connecting plate 11 in the direction perpendicular to the first connecting plate 11.

[0070] In one embodiment, the number of the second damping assemblies 5 is at least two, and the at least two second damping assemblies 5 are arranged along the walking direction of the detection vehicle b.

[0071] Another embodiment of the utility model further provides a detection device, referring to Figure 3 Figure 2 Figure 3 comprising: a detection vehicle b, the detection vehicle b comprising a detection unit b1 and a limiting wheel b2 connected with the detection unit b1, the limiting wheel b2 being used for abutting with the inner side or the outer side of the to-be-detected track a; the above-mentioned reference adaptive device W, the reference adaptive device W being located at the top of the detection unit b1, and the second damping assembly 5 being connected with the detection unit b1.

[0072] The detection vehicle b comprises a profile detection assembly and a flatness detection assembly. The profile detection assembly is used to detect the profile of the to-be-detected rail a. The flatness detection assembly is used to detect the flatness of the to-be-detected rail a.

[0073] In one embodiment, the detection vehicle b further comprises a walking wheel b3 connected with the detection unit b1, and the walking wheel b3 is used to contact the upper rail surface of the to-be-detected rail a.

[0074] Specifically, the limiting wheel b2 is fixedly connected with the detection unit b1, and is mainly used to clamp the inner side or the outer side of the to-be-detected rail a. The walking wheel b3 is used to drive the detection unit b1 to move along the upper rail surface of the rail a.

[0075] When the detection vehicle b walks in the walking direction on the region where the track gauge of the to-be-detected rail a has an offset, the front end of the detection vehicle b swings relative to the rear end. Through the deformation of the second elastic member 53 in the second damping assembly 5 in the direction perpendicular to the walking direction of the detection vehicle b and parallel to the second connecting plate 2, the limiting wheel b2 of the detection vehicle b abuts against the side wall of the to-be-detected rail a, so as to avoid the disengagement of the limiting wheel b2 of the detection vehicle b from the to-be-detected rail a. At the same time, when the detection vehicle b walks in the walking direction on the region where the track gauge of the to-be-detected rail a has an offset, the swing member 3 swings with the actual curve curvature change of the region where the to-be-detected rail a has an offset, so as to make the first connecting plate unit 1 rotate relative to the second connecting plate 2 in the plane parallel to the first connecting plate unit 1 and the second connecting plate 2. The relative rotation of the first connecting plate unit 1 relative to the second connecting plate 2 makes the first moving member 43 in the first damping assembly 4 compress the first elastic member 42 in the plane parallel to the first connecting plate unit 1 and the second connecting plate 2 and store a part of energy. Then, the first elastic member 42 releases the part of energy, and through the rebound of the first moving member 43, the first connecting plate unit 1 reversely rotates relative to the second connecting plate 2 in the plane parallel to the first connecting plate unit 1 and the second connecting plate 2, so as to make the detection vehicle b smoothly drive away from the region where the track gauge of the to-be-detected rail a has an offset. The stability of the detection reference of the profile detection of the to-be-detected rail a by the detection vehicle b is ensured, and the accuracy of the profile detection data is improved.

[0076] When the detection vehicle b drives to the region where the upper rail surface of the to-be-detected rail a has a defect, the third elastic member 62 in the third damping assembly 6 continuously applies a downward pressure to the detection vehicle b through compression, so as to make the walking wheel b3 apply a downward pressure to the to-be-detected rail a, and ensure that the walking wheel b3 and the upper rail surface of the to-be-detected rail a are always in a state of close contact. The stability of the relative position between the detection point and the upper rail surface of the to-be-detected rail a during the flatness detection of the to-be-detected rail a by the detection vehicle b is ensured, and the accuracy of the flatness detection data is improved.

[0077] The utility model discloses another embodiment still provides an intelligent polishing system, including polishing car and the detection device of above -mentioned embodiment, and the reference self -adaptation device W is located between polishing car and detection unit b1, and the second connecting plate 2 and polishing car are detachably connected.
