Detailed Description
The present invention will be described with reference to the accompanying drawings.
Fig. 1 shows a schematic diagram of a probe 100 for an eddy current flaw detector according to one embodiment of the present invention. As shown in fig. 1, the probe 100 for an eddy current flaw detector includes a body 20. The body 20 is connected to the eddy current flaw detector 10 through the lead 16, so that a detection eddy current can be emitted under the action of the eddy current flaw detector 10 to perform nondestructive testing on the element 15 to be tested.
As shown in fig. 1, a support bar 30 having a certain length is further coupled to a lower end of the body 20. Thus, the operator can lift the main body 20 to the air through the support rod 30, so that the main body 20 can be attached to the device 15 to be tested having a certain height or being located in the air, and the device 15 to be tested can be subjected to flaw detection.
In an actual flaw detection operation, since the device under test 15 often has a bent portion 151 or other irregular shape, an operator needs to rotate the main body 20 according to the bending condition of the device under test 15 to ensure that the main body 20 can be always attached to the device under test 15, thereby ensuring the accuracy of a detection result.
Therefore, when performing flaw detection on the to-be-detected element 15 with a certain height or in the air, an operator often needs to frequently rotate the supporting rod 30, and rotate the supporting rod 30 to drive the body 20 to rotate, so as to ensure the close fit between the body 20 and the to-be-detected element 15. At this time, since the arrangement direction of the support rods 30 is vertical, the difficulty of the operator rotating the support rods 30 is high. More importantly, because the supporting rod 30 is vertically arranged, an operator can only rotate the supporting rod 30 within a limited angle range, and the operation requirement on the site is difficult to meet, so that the detection accuracy is reduced.
Therefore, in the present invention, a rotatable connecting member 40 is further disposed between the body 20 and the supporting rod 30, so that the supporting rod 30 can rotate relative to the body 20 under the action of an external force. Therefore, in the detection process, when the body 20 moves to the bending portion 151 or other irregular shape of the element to be detected 15, the body 20 can rotate relative to the supporting rod 30 under the limitation of the element to be detected 15, so that the body 20 is ensured to be tightly attached to the element to be detected 15 on the premise of not rotating the supporting rod 30, and the detection accuracy is ensured.
Fig. 2 is a partially enlarged view of a circular region of a probe 100 for an eddy current flaw detector shown in fig. 1. As shown in fig. 2, the connecting member 40 is provided as a ratchet ring 50 connected between the body 20 and the support rod 30. The ratchet ring comprises a ratchet 52 and a rotating rod 55 connected to the ratchet 52, and the body 20 is fixedly connected to the rotating rod 55. When the body 20 moves to the bending portion 151 of the device under test 15, the ratchet 52 rotates under the action of the device under test 15, so as to allow the rotating rod 55 and the body 20 on the rotating rod 55 to rotate relative to the supporting rod 30. By this arrangement, the state of the body 20 can be adjusted without rotating the support rod 30, thereby ensuring that the body 20 is closely attached to the element 15 to be measured.
It should be noted that the structure and principle of such a ratchet device capable of rotating are well known to those skilled in the art, and a detailed description thereof will be omitted.
As shown in fig. 2, a protrusion 32 protruding out of the ratchet 52 is further provided on the rotary rod 30, so that a gap 36 is formed between the body 20 and the ratchet 52. Through the arrangement, the body 20 can be prevented from being directly connected with the ratchet wheel 52, so that the interference of the ratchet wheel 52 and the obstruction of the normal rotation of the body 20 to influence the normal flaw detection operation can be avoided.
In a preferred embodiment, a bearing (not shown) is further provided between the ratchet 52 and the rotating rod 55. The ratchet wheel is connected with the support rod through the bearing. It is easy to understand that the bearing can reduce the friction loss between the ratchet 52 and the rotating rod 55, and reduce the rotating friction between the ratchet 52 and the rotating rod 55, thereby protecting the ratchet 52 and the rotating rod 55.
In a preferred embodiment, the support rod 30 is provided as a telescopic rod. The operator can adjust the length of the support rod 30 according to the height of the device 15 to be measured, so that the probe 100 for an eddy current flaw detector of the present invention can be better applied to different working environments.
In a preferred embodiment, the support rod 30 is provided as a hollow tube. Through the arrangement, the quality of the supporting rod 30 can be reduced under the condition of the same length, so that the labor can be saved, and the operation difficulty of operators can be reduced.
Further, the support rod 30 is made of a carbon fiber material. This material has a lower density, which can further reduce the mass of the support bar 30, thereby further reducing the operational difficulty of the operator.
In addition, as shown in fig. 1, in a preferred embodiment, a handle 60 perpendicular to the support rod 30 is connected to the lower end of the rotation rod 30 far away from the body 20. The handle 60 is constructed in a horizontal state perpendicular to the support rod 30, so that it is more convenient for an operator to hold the handle 60, thereby facilitating the operator to operate the support rod 30.
Further, a screw hole (not shown) is formed in a side wall of a lower end of the rotary bar 30, and the handle 60 is screw-coupled to the rotary bar 30. By such a connection method, the operator can detach the handle 60 at any time, and the storage space of the rotating lever 30 and the handle 60 after the flaw detection operation is finished can be saved.
The operation of the probe 100 for an eddy current flaw detector according to the present invention is briefly described below.
The utility model discloses a probe 100 for eddy current flaw detector is used for detecting a flaw the operation to the higher element 15 that awaits measuring of height. During operation, a worker first needs to mount the support rod 30 on the body 20, and then adjust the length of the body 20 so that the body 20 can be tightly attached to the device 15 to be tested. At this time, the supporting rod 30 can drive the body 20 to move, so as to perform flaw detection operation.
When the body 20 moves to the position of the bending portion 151 of the element 15 to be detected, under the action of the connecting member 40, the body 20 can rotate relative to the supporting rod 30, so that the body 20 is always attached to the element 15 to be detected on the premise of not rotating the supporting rod 30, and the accuracy of the flaw detection operation can be ensured.
Finally, it should be noted that the above description is only a preferred embodiment of the present invention, and should not be construed as limiting the present invention in any way. Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing examples, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included within the scope of the present invention.
