[0033] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0034] In this application, the terms "installed," "disposed," "provided with," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections, indirect connections through an intermediary, or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0035] In addition, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may or may not be the same in type and configuration), and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0036] The technical solution of the present application will be further described below with reference to specific embodiments and drawings.

[0037] See also Figure 1 The present invention provides a rail flaw detection probe fixture 1, comprising a plate 11, a receiving assembly 12, and a rod assembly 13. The plate 11 has a first surface 111 and a second surface 112, which are opposite to each other. The plate 11 is configured to be mounted on the side of a flaw detector vehicle, with the first surface 111 facing the vehicle. The receiving assembly 12 is disposed on the second surface 112 and is used to accommodate the probe. The rod assembly 13 is connected to the second surface 112 and is spaced apart from the receiving assembly 12. The rod assembly 13 is used to route the probe's wiring harness.

[0038] It should be noted that when the operator is conducting flaw detection with a handheld probe, he or she is generally positioned on the side of the flaw detector body. In addition, when changing the flaw detection position, the operator generally needs to move the flaw detector body.

[0039] In this embodiment, when the operator needs to replace the probe, he first removes the wiring harness of the probe to be replaced in the accommodating component 12 from the rod component 13, then takes the probe out of the accommodating component 12 for replacement, puts the replaced probe into the accommodating component 12, and wraps the wiring harness of the replaced probe around the rod component 13, thereby completing the replacement of the probe.

[0040] In this embodiment, since operators typically hold a probe to the side of the flaw detector body when conducting flaw detection, the plate 11 is positioned on the side of the flaw detector body. This reduces the distance between the operator and the rail flaw detection probe fixture 1, making it easier for the operator to directly remove the probe from the receiving assembly 12. This facilitates the operator's replacement of the probe based on actual site conditions and reduces the time required for the operator to replace the probe. Furthermore, accommodating the probe in the receiving assembly 12 supports the probe, preventing it from falling, thereby protecting the probe.

[0041] In addition, in this embodiment, when the probe is accommodated in the accommodating assembly 12, the wiring harness of the probe can be wrapped around the rod assembly 13 to prevent the wiring harness from falling vertically and shaking due to inertia or even dragging on the ground to cause damage to the wiring harness. At the same time, it also prevents the wiring harness from getting stuck and causing the probe to fall, keeping the wiring harness neat and orderly, and facilitating the management and maintenance of the wiring harness by the operator.

[0042] Please continue reading Figure 1 In some embodiments, the accommodating component 12 is provided with a communicating opening 121 and an accommodating groove 122 . The accommodating groove 122 is used to accommodate the probe, and the opening 121 allows the probe to enter or exit the accommodating groove 122 .

[0043] In this embodiment, when the operator needs to replace the probe, he first removes the wiring harness of the probe to be replaced in the receiving slot 122 from the rod assembly 13, then takes the probe out of the receiving slot 122 for replacement, puts the replaced probe into the receiving slot 122, and wraps the wiring harness of the replaced probe around the rod assembly 13, thereby completing the replacement of the probe.

[0044] By providing the opening 121 , it is convenient for the operator to directly take out or put the probe into the receiving groove 122 through the opening 121 , thereby simplifying the steps for the operator to replace the probe and saving the operator's time in replacing the probe.

[0045] In some other embodiments, a cover body may also be provided to be connected to the receiving assembly 12 to selectively close or open the receiving slot 122 .

[0046] In some embodiments, the opening 121 is oriented perpendicular to the second surface 112 .

[0047] It is understood that since the operator is generally positioned to the side of the flaw detector body when holding the probe for flaw detection, the second surface 112 faces the operator when the operator is holding the probe for flaw detection. The opening 121 is oriented perpendicular to the second surface 112, that is, the opening 121 faces the operator. When replacing the probe, the operator can directly obtain information about the probe in the receiving slot 122 through the opening 121, which can reduce the frequency of the operator removing a probe that is not the preset probe.

[0048] In some other embodiments, the opening 121 may be oriented parallel to the second surface 112 .

[0049] In some embodiments, the sidewall of the receiving groove 122 is provided with a ridge (not shown in the figure), and the ridge is used to abut against and fix the probe.

[0050] It is understandable that because opening 121 is oriented perpendicular to second surface 112, the probe within receiving slot 122 may fall out through opening 121 during movement of the flaw detector vehicle due to factors such as bumps, thereby damaging the probe. To address this issue, in this embodiment, ridges are provided on the sidewalls of receiving slot 122. When the probe is received in receiving slot 122, the ridges abut against the outer surface of the probe, forming a transition fit or interference fit, thereby securing the probe and preventing it from falling. When an operator needs to remove the probe from receiving slot 122, they can do so with minimal force.

[0051] The convex strips may be rubber strips or other elastic strips, which are not limited here.

[0052] In some other embodiments, a buckle may be provided on the side wall of the receiving groove 122 to engage the probe through the buckle to achieve the purpose of fixing the probe.

[0053] Please continue reading Figure 1 In some embodiments, the accommodating assembly 12 includes a first accommodating member 123 and a second accommodating member 124 that are spaced apart. The first accommodating member 123 and the second accommodating member 124 are respectively used to accommodate probes of different specifications.

[0054] For example, the first receiving member 123 can accommodate a 70° handheld probe, and the second receiving member 124 can accommodate a 0°+37° handheld probe.

[0055] In some other embodiments, the first accommodating member 123 and the second accommodating member 124 may also be used to accommodate probes of the same specifications.

[0056] Please continue reading Figure 1 In some embodiments, the rod assembly 13 includes a first rod member 131 and a second rod member 132 that are spaced apart. The first rod member 131 is adjacent to the first accommodating member 123 and is used to wind the wiring harness of the probe accommodated in the first accommodating member 123. The second rod member 132 is adjacent to the second accommodating member 124 and is used to wind the wiring harness of the probe accommodated in the second accommodating member 124.

[0057] The first rod 131 is used to wind the wiring harness of the probe accommodated in the first accommodating member 123, and the second rod 132 is used to wind the wiring harness of the probe accommodated in the second accommodating member 124, which can prevent the wiring harnesses of different probes from being tangled together and avoid the increase in the time of replacing probes due to the confusion of the wiring harnesses.

[0058] In some other embodiments, the first rod 131 and the second rod 132 may be coaxially arranged, with both ends of the first rod 131 connected to the second surface 112 and the second rod 132 respectively, and a spacer connected between the first rod 131 and the second rod 132 .

[0059] In some embodiments, at least one of the first rod 131 and the second rod 132 is located between the first receiving member 123 and the second receiving member 124 .

[0060] In some other embodiments, the first rod 131 may be located on a side of the first accommodating member 123 away from the second accommodating member 124 , and the second rod 132 may be located on a side of the second accommodating member 124 away from the first accommodating member 123 .

[0061] In some embodiments, the first rod 131 and the second rod 132 are both located between the first receiving member 123 and the second receiving member 124 .

[0062] In some other embodiments, one of the first rod 131 and the second rod 132 can be positioned between the first receiving member 123 and the second receiving member 124 .

[0063] Please continue reading Figure 1 In some embodiments, the rail flaw detection probe fixing device 1 further includes a limiting member 14 , which is connected to an end of the rod assembly 13 away from the second surface 112 .

[0064] After the probe's wiring harness is wound around the rod assembly 13, it may slide axially along the rod assembly 13 and away from the second surface 112, ultimately detaching from the rod assembly 13. To address this issue, this embodiment provides a stopper 14 at the end of the rod assembly 13 away from the second surface 112. The stopper 14 prevents the probe's wiring harness from sliding axially along the rod assembly 13 and falling off after being wound around the rod assembly 13.

[0065] In some other embodiments, a groove may be provided on the outer surface of the rod assembly 13 , and the wiring harness may be confined within the groove.

[0066] Please continue reading Figure 1 In some embodiments, a receiving member 16 may be further provided on the second surface 112. The receiving member 16 has a receiving groove 161. The depth direction of the receiving groove 161 may be parallel to the second surface 112. In other words, the receiving opening 162 of the receiving member 16 may be oriented parallel to the second surface 112. The receiving groove 161 may receive brief documents such as damage notices and suspected damage proofreading sheets.

[0067] In some other embodiments, the receiving member 16 may also be disposed on the first surface 111 .

[0068] Please also refer to Figure 1 and Figure 2 In some embodiments, the rail flaw detection probe fixture 1 further includes two spaced-apart raised portions 15 and a connector (not shown). Both raised portions 15 are connected to the first surface 111 and each has a through-hole 151. The connector passes through the through-hole 151 and connects the raised portion 15 to the side of the flaw detector body.

[0069] The connecting member may be a flexible connecting member, such as a rope, a cable tie or a chain, or a rigid connecting member, such as a bolt.

[0070] The two spaced-apart protrusions 15 are connected to the side of the flaw detector body via a connector, forming a relatively stable support structure, which helps to reduce the vibration and movement of the rail flaw detection probe fixture 1 relative to the flaw detector body during the detection process.

[0071] In some other embodiments, the through hole 151 may also be disposed in the plate 11 and pass through the first surface 111 and the second surface 112 .

[0072] While the present invention has been described with reference to preferred embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, the various technical features described in the various embodiments may be combined in any manner, provided no structural conflicts exist. The present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
