Detailed Description
Further details are provided below with reference to the specific embodiments.
As shown in fig. 1 and 2, the present utility model provides an ultrasonic nondestructive testing device for a narrow space, comprising a handle 1, an extension rod 2, a rotary ratchet part 3 and a probe clamping device. The probe holder comprises a probe holder housing 5 and a knob screw 6.
The handle 1 is connected with the extension rod 2 through threads, the handle 1 is provided with internal threads, the extension rod 2 is provided with external threads, and the internal threads are matched with the external threads. The extension rod 2 is connected to the rotary ratchet member 3, preferably the extension rod 2 is welded to the rotary ratchet member 3. The rotating ratchet part 3 can rotate 270 degrees, and the rotating ratchet part can rotate to a proper position and can be fixed in direction through the ratchet limiting device 4 on the rotating ratchet part 3. That is, the inspector can rotate the rotary ratchet member 3 to make the probe angle to a proper position according to the on-site inspection condition, the ratchet limiting device 4 is mounted on the outer ring of the rotary ratchet member 3, and the limiting device is lifted by pressing the ratchet limiting device 4, so that the rotary ratchet member 3 can be rotated. After rotating in place, the ratchet limiting device 4 is put down and clamped on the rotating ratchet part 3, so that the ratchet limiting device is fixed, and the positioning effect is achieved.
Preferably, the maximum distance of extension of the extension rod 2 is 800mm, so as to prevent the shaking of the device with too long extension from causing the scanning to be out of order, and the inspector is not well mastered.
The rotating ratchet part 3 is connected with the probe clamping device. Preferably, the rotating ratchet member 3 and the probe holder housing 5 are welded together by a small pipe (stub).
The knob screw 6 can be screwed back and forth to clamp the probe. The knob screw 6 manually rotates and adjusts and clamps the probe according to the size of the probe, fixes the front, back, left and right directions of the probe, and avoids the probe from swinging in the detection process, thereby ensuring the detection accuracy.
The number of the knob screws 6 is 4, and the adjacent 2 knob screws 6 are arranged at 90 degrees, and the whole knob screws are in a cross shape.
The top of each knob screw 6, which is in contact with the probe, is covered with an anti-slip rubber.
The knob screw 6 on the probe clamping device can manually adjust the telescopic range, and is suitable for probes of various sizes.
Preferably, the outer layer of the handle 1 is wrapped by an anti-slip rubber sleeve for being held by a detector, so that the anti-slip handle is beneficial to slipping.
The ultrasonic nondestructive testing device for the narrow space provided by the utility model has the advantages that on one hand, the accessibility of field test is greatly reduced, on the other hand, the work of disassembling and insulating the rack is omitted in the test, and the test time is saved.
When in field inspection, an inspector should select a probe to be used according to a program or a process card. The probe is mounted on a probe clamping device consisting of a probe clamping device shell 5 and a knob screw 6, and the probe is fixed by rotating the knob screw 6 so as not to fall off. The inspector then holds the handle 1 and stretches the wand 2 to bring the probe to the inspection position, as the case may be. And then the device is taken out according to the visual angle of the weld joint position, the ratchet wheel limiting device 4 is pressed to rotate the rotating ratchet wheel part 3, and the ratchet wheel limiting device 4 is released to position the rotating ratchet wheel part 3. Thereby bringing the probe to a predetermined angle. The device is then sent in again, and then the subsequent inspection and detection work is carried out.
The utility model is used for reducing places where hands of detection personnel cannot reach in application of ultrasonic nondestructive inspection in narrow space, thereby reducing unreachable areas and increasing the credibility of detection results. Meanwhile, the work of disassembling and insulating the heat and building the shelf can be reduced to a certain extent. The efficiency of field operation is greatly improved. The tool is suitable for manual ultrasonic nondestructive testing operation, and the device has a screwed clamping design and a rotary design, and is suitable for most manual ultrasonic nondestructive testing probes.
