Description

Technical Field

[0001] The utility model relates to a railway wheel online detection probe array, in particular to a railway wheel online detection probe array with probes capable of being quickly disassembled and assembled. Background Art

[0002] Online automatic flaw detection for locomotive wheels: As locomotive wheels pass, an array of detection probes contacts the wheels for online inspection. Because the probe array is constantly impacted by the wheels, the probes within it periodically become damaged. Repairing and replacing damaged probes is essential during equipment operation. Each probe array consists of three modules, each containing multiple sets of probes.

[0003] The following deficiencies were found during the inspection and maintenance of the current detection probe array:

[0004] (1) When inspecting each set of probes, the entire stainless steel pressure plate needs to be removed, and the damaged probes need to be replaced and then reinstalled. During the reinstallation process, each probe needs to be manually reinstalled one by one because the spring is not fixed. Even if only one probe needs to be replaced, the entire probe needs to be disassembled and then reinstalled one by one, which greatly reduces work efficiency.

[0005] (2) The detection probe array is installed between the main rail and the auxiliary rail, and the maintenance space is small. The existing maintenance steps impose many restrictions on maintenance personnel, making it impossible to complete the task flexibly. Summary of the Invention

[0006] In view of the shortcomings and deficiencies in the prior art, the purpose of the present invention is to provide a railway wheel online detection probe array with quickly detachable probes, which can quickly detach and assemble probes, reduce the time required for detachment and assembly, and improve detachment and assembly efficiency.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] Reference Figures 1 to 2 As shown, the railway wheel online detection probe array 2 with quickly detachable probes of this embodiment includes a probe 21 , a cover plate 22 , an auxiliary plate 23 , a cover plate stud 24 , an auxiliary plate stud 25 , a probe spring 26 and a base 27 .

[0029] A plurality of probes 21 are disposed on the base 27 , and the bottom of each probe 21 is disposed on the base 27 via a probe spring 26 .

[0030] The upper parts of the plurality of probes 21 are integrally embedded in an auxiliary plate 23 , and the auxiliary plate 23 is fixed on the top of the base 27 via auxiliary plate studs 25 .

[0031] The auxiliary plate 23 is provided with a plurality of shaping holes, the positions of which match the positions of the probes 21 , so that the upper part of the probes 21 protrude from the shaping holes. That is, the shaping holes are arranged on the auxiliary plate 23 according to the arrangement mode and angle of the existing probes 21 .

[0032] The shape of the shaping hole is specially customized, including a first latching position 231 and a second latching position 232 , and a convex area 233 is provided at the second latching position 232 .

[0033] like Figure 3 As shown, when the probe 21 is located at the first locking position 231 , the probe spring 26 below the probe 21 can be pressed so that the probe 21 does not pop out completely in this state.

[0034] like Figure 4 As shown, when the probe 21 needs to be removed, slightly press down the probe 21, twist the probe 21 clockwise about 20° to reach the second locking position 232, push the probe 21 outward to cause the probe spring 26 to push the probe 21 to pop out from the outer convex area 233 of the molding hole, and take out the probe 21 and the probe spring 26. During this process, the other probes 21 under the auxiliary plate 23 are fixed and kept stationary by the auxiliary plate 23.

[0035] That is, the auxiliary plate 23 has the function of removing a single probe 21 together with the probe spring 26 through the above disassembly and assembly steps, while the remaining probes 21 do not move.

[0036] Preferably, the shaped hole is arranged at a position away from the original cover plate stud 24 .

[0037] Preferably, a plurality of auxiliary plate studs 25 are provided, because the auxiliary plate 23 will not be removed during the replacement of a certain probe 21, so the number of fixing points is increased to ensure stability.

[0038] Preferably, the size of the auxiliary plate studs 25 is smaller than the cover plate studs 24 , and the position of the auxiliary plate studs 25 avoids the original cover plate studs 24 .

[0039] Preferably, the auxiliary plate 23 is a stainless steel plate.

[0040] A cover plate 22 is provided above the auxiliary plate 23 and is fixed to the base 27 via cover plate studs 24. The cover plate 22 has a plurality of through holes, the positions of which match those of the probe 21, so that the upper portion of the probe 21 protrudes from the through holes.

[0041] The railway wheel online inspection probe array 2 with quick-detachable probes in this embodiment consists entirely of the original probe array components, except for the auxiliary plate 23 and auxiliary plate studs 25. The auxiliary plate 23 is integrated into the original probe array and mounted on the base 27 via the auxiliary plate studs 25, located between the cover plate 22 and the probes 21.

[0042] When the cover plate 22 is removed, the auxiliary plate 23 and the probe 21 are in the following state: Figure 3 As shown, the probe spring 26 is pressed by the customized hole shape so that it will not pop out completely in this state.

[0043] like Figure 4 As shown, when the probe 21 needs to be removed, slightly press down the probe 21, twist the probe 21 clockwise about 20° (in the direction indicated by the arrow in the figure) to reach the second locking position 232, and push the probe 21 outward so that the probe spring 26 pushes the probe 21 to pop out from the outer convex area 233 of the molding hole, and remove the probe 21 and the probe spring 26. During this process, the other probes 21 under the auxiliary plate 23 are fixed and kept stationary by the auxiliary plate 23.

[0044] When a new probe 21 needs to be installed, the probe 21 and the probe spring 26 at the end are placed into the shaped hole of the auxiliary plate 23, and the above removal sequence is reversed to install the new probe 21. During this process, the other probes 21 are fixed by the auxiliary plate 23 and remain unchanged.

[0045] The working principle and process of the railway wheel online detection probe array 2 with quick detachable probes of this embodiment for quick detachable assembly are as follows:

[0046] When the probe array needs to be repaired and some damaged probes 21 need to be replaced, maintenance personnel can perform the repair through the following steps.

[0047] (1) Remove the cover plate 22.

[0048] (2) Replace the damaged probe 21: slightly press down the probe 21, twist the probe 21 clockwise about 20 degrees, and push the probe 21 outward so that the probe spring 26 pushes the probe 21 out of the convex area 233, and remove the probe 21, the probe spring 26 and the signal line.

[0049] (3) Insert the new probe spring 26 and the signal wire along the auxiliary plate 23 , and pull out the signal wire from the 20 mm gap between the base 27 and the auxiliary plate 23 .

[0050] (4) After ensuring that the probes 21 are all in their corresponding positions, reinstall the cover plate 22.

[0051] Among them, removing the probe 21 only requires two steps of twisting and turning, which not only reduces the deviation of the non-replaced probe caused by accidental touch and collision during work or maintenance, but also greatly reduces the maintenance time and improves the disassembly and assembly efficiency.

[0052] The optimal manpower consumption for the above disassembly and assembly steps is 1 person.

[0053] Except for step (1) of removing the cover plate 22 , the above-mentioned disassembly and assembly steps can be performed without the aid of tools, thus saving resources.

[0054] The above description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention. Any modification, equivalent replacement and improvement made within the spirit and principle of the present invention shall be included in the scope of protection of the claims of the present invention.
