Description

Technical Field

[0001] The utility model relates to an on-line detection probe array for railway wheels, in particular to a probe array device with quickly detachable and installable probes. Background Art

[0002] When a railway locomotive wheel passes by, the detection probe array needs to contact the wheel to perform on-line detection. Since the detection probe array is often impacted by the wheel, the probes therein will be periodically damaged. It is essential to repair and replace the damaged probes during the use of the equipment.

[0003] The detection probe array includes multiple probes. The following deficiencies are found during the repair process: (1) When repairing each probe, the whole stainless steel pressing plate needs to be removed. After replacing the damaged probe, it is reinstalled. However, when reinstalling the probe, since the spring is not fixed, each probe needs to be manually reinstalled one by one; even if only one probe needs to be replaced, the whole probe needs to be disassembled and then reinstalled one by one, which greatly reduces the work efficiency. (2) The detection probe array is installed between the main rail and the auxiliary rail, and the repair space is narrow. The existing repair steps have many restrictions on the repair personnel and cannot complete the task flexibly. Summary of the Invention

[0004] Aiming at the shortcomings and deficiencies existing in the prior art, the purpose of the utility model is to provide a probe array device with quickly detachable and installable probes, which can quickly disassemble and install the probes, reduce the time required for disassembly and installation, and improve the disassembly and installation efficiency.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A probe array device with quickly detachable and installable probes, the probe array device includes probes, an array cover plate, a probe cover plate, columns, probe springs and a base; the base is provided with a plurality of cavities, the bottom of the probe and the probe spring sleeved outside the bottom of the probe are placed in the cavities; an array cover plate is arranged above the base, and the whole probe and the probe spring are integrally embedded and can pass through the regular holes on the array cover plate; the probe cover plate is arranged above the regular holes of the array cover plate, and the probe cover plate is provided with through holes, and only the head of the probe protrudes from the through holes to limit the position of the probe.

[0007] Further, the regular holes include arc parts on four sides and right angles between adjacent arc parts. The four right angles are connected to form a square. The overall shape of the regular holes is the same as the top view superposition shape of the probe and the probe spring, and the size is slightly larger.

[0008] Further, the overall size of the arc part is slightly larger than the size of the probe spring, so the probe spring passes through the regular hole; the overall size of the square is the same as or slightly larger than the size of the probe, so the whole probe passes through the regular hole.

[0009] Further, the regular holes are arranged according to the number, arrangement pattern and angles of the probes.

[0010] Further, the shape of the through hole is the same as the top view shape of the probe head, and the size of the through hole is larger than the size of the probe head but smaller than the size of the square step of the probe.

[0011] Further, the probe cover plate is fixed to the regular holes by screws.

[0012] Further, the number of the probe cover plates provided is the same as the number of the probes.

[0013] Further, a plurality of columns are detachably mounted and fixed above the base, and an array cover plate is fixedly arranged by the base being suspended and supported by the columns.

[0014] Further, the array cover plate is a stainless steel plate.

[0015] Further, the probe cover plate is a stainless steel plate or an aluminum alloy plate.

[0016] For the probe array device of the quick-release and quick-installation probe of the present utility model, regular holes are arranged on the array cover plate, and their sizes allow the probes and the probe springs to pass through; through holes are arranged on the probe cover plate, and only the exposed part (probe head) of the probe can pass through; the above regular holes correspond one by one to the arrangement of the probes on the base, and each probe is integrally fitted into the probe cover plate and the array cover plate, facilitating the probe head to protrude from the through holes.

[0017] The advantages of the present utility model are as follows:

[0018] (1) For the probe array device of the quick-release and quick-installation probe of the present utility model, only the corresponding probe cover plate needs to be removed to take out a single probe, reducing the deviation of non-replaced probes caused by accidental touch and collision during maintenance work; to replace all the probes, only the array cover plate needs to be removed directly, which is very convenient.

[0019] (2) By using the probe array device of the quick-release and quick-installation probe of the present utility model, the disassembly and assembly steps of the original overhaul probe array are improved, greatly reducing the overhaul time, and helping the overhaul personnel to more efficiently utilize the limited skylight point time to overhaul and disassemble and assemble the probes, improving the disassembly and assembly efficiency.

[0029] The present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0030] Refer to Figures 1 to 5 As shown, the probe array device of the quick-release and quick-installation probe in this embodiment includes a probe 1, an array cover plate 2, a probe cover plate 3, a column 4, a probe spring 5, and a base 6;

[0031] Among them, the base 6 is provided with a plurality of cavities for placing the probe spring 5 and the probe bottom 13. Specifically, each probe bottom 13 is sleeved with a probe spring 5 and placed in the above-mentioned cavity of the base 6.

[0032] A plurality of columns 4 are detachably installed and fixed above the base 6. The base 6 is fixedly provided with an array cover plate 2 by being suspended and supported by the columns 4.

[0033] A plurality of probes 1 and the probe springs 5 sleeved thereon can be integrally inserted and passed through the array cover plate 2.

[0034] The array cover plate 2 is provided with a plurality of regular holes, and the regular holes are arranged according to the number, arrangement mode, and angle arrangement of the probes 1 on the existing array.

[0035] The regular hole includes an arc part on four sides and a right angle between adjacent arc parts, and the four right angles are connected to form a square (such as Figure 4As shown in the figure, the overall shape of the regular holes is consistent with the top-down superimposed shape of the probe 1 and the probe spring 5 outside the probe 1: the overall size of the arc part is slightly larger than that of the probe spring 5, so the probe spring 5 can pass through the regular holes; the overall size of the square is the same as or slightly larger than that of the probe 1, so the probe 1 can completely pass through the regular holes. That is, the probe 1 and the probe spring 5 can pass through the regular holes of the array cover plate 2.

[0036] Preferably, the array cover plate 2 is a stainless steel plate.

[0037] The probe cover plate 3 is fixed to each regular hole of the array cover plate 2 by screws. The probe cover plate 3 is also arranged according to the number, arrangement and angle of the existing array probes 1.

[0038] A through hole 31 is provided on the probe cover plate 3. The through hole 31 is set as a rectangle and is consistent with the top-down shape of the probe head 12. The size of the through hole 31 is larger than that of the probe head 11, but the size of the through hole 31 is smaller than that of the probe square step 12. Therefore, when using the probe cover plate 3, only the probe head 11 can pass through while blocking the probe square step 12 from passing through (as Figure 5 shown), that is, only the probe head 11 protrudes from the through hole 31 so that the probe cover plate 3 can fix and limit the probe 1.

[0039] Preferably, the probe cover plate 3 is a stainless steel plate or an aluminum alloy plate.

[0040] Except for the array cover plate 2 and the probe cover plate 3, all parts of the quick-disassembly and quick-assembly probe's probe array device in this embodiment are original probe array parts. Through the design of this embodiment, it can be easily replaced and upgraded by replacing the original array cover plate, and the production cost is relatively low.

[0041] As Figure 2 shown, when the probe cover plate 3 is installed on the array cover plate 2, it can press the probe spring 5 below the probe 1 so that it will not pop out completely in this state.

[0042] As Figure 1 shown, when a specific probe 1 needs to be removed, first remove the corresponding probe cover plate 3, release the corresponding probe spring 5 that is pressed, the probe 1 pops out, and take out the probe 1 and the probe spring 5. During this process, the other probes 1 are all fixed and held in place by the probe cover plate 3.

[0043] That is, the probe cover plate 3 has the function of taking out a single probe 1 together with the probe spring 5 through the above disassembly and assembly steps, and the other probes 1 do not move.

[0044] As Figure 1 shown, when all the probes 1 need to be removed, directly remove the array cover plate 2, and all the probes 1 will pop out. At that time, all the probes 1 and the probe springs 5 can be taken out.

[0045] In summary, there are two ways to disassemble the probe 1: one is fixed-point disassembly, where the corresponding probe cover 3 is disassembled to remove the corresponding probe 1; the other is complete disassembly, where the array cover 2 is removed from the base 6 as a whole, and the probes 1 and probe springs 5 on all bases 6 can be repaired. The above two disassembly methods are selected and implemented according to actual needs.

[0046] When it is necessary to reinstall a single or multiple new probes 1, the probe bottom 13, the probe square step 12 and the probe spring 5 are placed together under the probe cover 3, and the above disassembly sequence is reversed to install the new probe 21. During the process, the other probes 1 are fixed by the probe cover 3 and remain unchanged.

[0047] When it is necessary to reinstall all new probes 1, the probes 1 and the probe springs 5 are placed together in the cavity of the base 6, then the array cover 2 with the probe cover 3 already assembled is covered. After the probe heads 11 are aligned with the through holes 31 of the probe cover 3 and protruded, the array cover 2 is fixed by the column 4 to complete the installation.

[0048] The quick disassembly and assembly of the probe array device of the quick-release and quick-assembly probe in this embodiment not only reduces the offset of non-replaced probes caused by accidental touch and collision during work or maintenance, but also greatly reduces the maintenance time and improves the disassembly and assembly efficiency.

[0049] The above disassembly and assembly steps can achieve the effect of being completed by only one person and common tools, saving manpower and material resources.

[0050] The above is only the preferred embodiment of the present invention and does not constitute a limitation on the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
