Description

Technical Field

[0001] The utility model relates to the technical field of weld detection, in particular to an ultrasonic weld detection device. Background Art

[0002] At present, ultrasonic detection technology has been widely used in the field of weld detection. For example, when it is necessary to detect pipeline welds, people usually need to make the ultrasonic detector move in a circular motion along the weld area of ​​the pipeline to be tested to detect the weld. However, the method of using a manual handheld ultrasonic detector for detection requires manual labor to first find the position of the weld and then slowly move in a circular motion to detect the weld. This is not only complicated in operation, but also has the disadvantages of slow weld position positioning and low detection accuracy. Especially when it is necessary to detect the welds of a batch of pipe fittings, the disadvantages of low detection efficiency and detection accuracy are more obvious. In addition, although there is a ring locator in the prior art that can move in a circular motion along the pipeline, there is still the problem that the pipeline weld position cannot be quickly located and the detection efficiency is low.

[0003] Therefore, there is an urgent need for an ultrasonic weld detection device to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the problems of slow pipeline weld positioning speed and slow detection speed in the prior art for pipeline weld detection, and provides an ultrasonic weld detection device.

[0014] Optionally, the detector includes a camera for acquiring the position of the weld on the pipe.

[0015] Optionally, a rotating mechanism for driving the pipe to rotate is also included.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0024] The utility model provides an ultrasonic weld detection device, such as Figure 1 As shown, the ultrasonic weld detection device includes a horizontal moving positioning mechanism, a vertical moving positioning mechanism, a detector 5 and a pipe moving positioning mechanism;

[0025] The vertical frame 3 of the vertical moving positioning mechanism is vertically installed on the horizontal moving positioning mechanism, and a first track is arranged on the vertical frame 3 along the vertical direction, a cantilever 4 is arranged on the first track, a detector 5 is arranged at the end of the cantilever 4 extending outward, and the pipe moving positioning mechanism is arranged below the detector 5.

[0026] According to the above technical scheme, based on the ultrasonic weld detection device, through the joint action of the horizontal moving positioning mechanism, the vertical moving positioning mechanism, the pipe moving positioning mechanism and the detector, in actual application, the pipe weld can be quickly positioned and detected, which is particularly suitable for the rapid detection of batch pipe welds.

[0027] The ultrasonic weld detection device described in the utility model, in a preferred case, is as follows Figure 1 As shown, the horizontal movement and positioning mechanism includes two parallel first slide rails 1 and a sliding plate 2 mounted on the two first slide rails 1, the sliding plate 2 is provided with a second track, and the vertical frame 3 is vertically mounted on the second track, so as to realize the forward, backward, left and right movement and positioning of the detector 5, and then by cooperating with the detector 5 to move up and down along the first track, it is possible to realize the rapid positioning and detection of the positions of pipeline welds of different sizes. Specifically, the sliding plate 2 can be moved along the two first slide rails 1 under manual action, and can also be moved along the first slide rail 1 under the drive of a motor. Preferably, the sliding plate 2 moves along the first slide rail 1 under the drive of a motor to improve the positioning efficiency of the pipeline weld. Similarly, the vertical frame 3 and the cantilever 4 are preferably driven by a motor to move on the second track and the first track respectively.

[0028] In a further preferred embodiment, the detector 5 includes a camera for acquiring the position of the weld on the pipe, so that in actual application, the positioning of the pipeline weld can be achieved more quickly by setting the camera.

[0029] In the ultrasonic weld detection device of the utility model, in a preferred case, the pipe moving and positioning mechanism includes a second slide rail 6, and at least two sliding supports 7 are provided on the second slide rail 6, and two support wheels are provided on the upper end of the sliding support 7. By providing at least two sliding supports 7 on the second slide rail 6, in actual application, the rapid transportation of the pipeline with the weld can be realized by using it in conjunction with the pipeline lifting device, and the two support wheels are further provided for the rotation of the pipe. In actual application, when a conventional detector is used, the pipe can also be rotated manually for detecting the weld. Preferably, the ultrasonic weld detection device also includes a rotating mechanism for driving the pipe to rotate; the rotating mechanism is a rotating clamp, and the base of the rotating clamp is installed on the second slide rail 6 of the pipe moving and positioning mechanism. After the rapid positioning of the weld position is realized by the horizontal moving and positioning mechanism, the vertical moving and positioning mechanism and the pipe moving and positioning mechanism, the pipe can be driven to rotate by the rotating clamp to realize accurate and rapid detection of the weld. Of course, an annular detector can also be used directly. However, when an annular detector is used to detect different pipe fittings, there is a problem that the annular detector needs to be frequently disassembled and assembled for detection. Although the detection accuracy can be improved compared to manual detection, the detection efficiency is low.

[0030] The number of the sliding support members 7 is determined according to the length of the pipeline, and the stability of the pipeline when moving along the second slide rail 6 can be ensured. The sliding support member 7 can move along the second slide rail 6 manually or driven by a motor. Preferably, the sliding support member 7 moves along the second slide rail 6 driven by a motor to improve the positioning efficiency of the pipeline weld. Specifically, when the number of the sliding support members 7 is more than 2, the middle sliding support member 7 can only have a supporting function.

[0031] In the ultrasonic weld detection device of the utility model, in a preferred case, the outer surface of the support wheel is coated with a buffer layer to prevent damage to the surface of the pipe when taking and placing the pipe and rotating the pipe. Specifically, the buffer layer can be made of polyethylene foam plastic, and of course, it can also be made of other materials with the same function.

[0032] In the ultrasonic weld detection device of the utility model, in a preferred case, the first slide rail 1 of the horizontal moving positioning mechanism and the second slide rail 6 of the pipe moving positioning mechanism are arranged in parallel. Figure 1 As shown, in actual application, the welds of pipes of different sizes can be quickly located by moving the detector 5 up, down, left, right, forward and backward, and the welds can be detected at appropriate positions.

[0033] In the ultrasonic weld detection device of the utility model, in a preferred case, the detector 5 is detachably mounted on the end portion of the cantilever 4 extending outward, so that different detectors 5 can be replaced according to pipes of different sizes and detection accuracy requirements.

[0034] The present invention will be described in detail below through embodiments, but the protection scope of the present invention is not limited thereto.

[0037] The vertical frame 3 of the vertical moving positioning mechanism is vertically installed on the horizontal moving positioning mechanism, and a first track is arranged on the vertical frame 3 in the vertical direction, a cantilever 4 is arranged on the first track, a detector 5 is arranged at the end of the cantilever 4 extending outward, and the pipe moving positioning mechanism is arranged below the detector 5;

[0038] Specifically, the horizontal movement and positioning mechanism includes two parallel first slide rails 1 and a sliding plate 2 mounted on the two first slide rails 1, the sliding plate 2 is provided with a second track, and the vertical frame 3 is vertically installed on the second track; the pipe moving and positioning mechanism includes a second slide rail 6, the second slide rail 6 is equipped with two sliding support members 7, and the upper end of the sliding support member 7 is provided with two support wheels; the outer surface of the support wheel is covered with a buffer layer; the buffer layer is made of polyethylene foam plastic; the first slide rail 1 of the horizontal movement and positioning mechanism and the second slide rail 6 of the pipe moving and positioning mechanism are arranged in parallel; the detector 5 is detachably mounted on the end of the cantilever 4 extending outward.

[0039] In actual application, the pipe to be tested is placed on the two sliding supports 7 on the second slide rail 6 through a lifting device, and then the two sliding supports 7 are driven to move synchronously to move the weld position of the pipe to the bottom of the detector 5. The detector 5 can also be linked through the first slide rail 1, the first track and the second track to move the weld position of the pipe to the bottom of the detector 5 at the fastest speed for easy detection. Finally, the circumferential detection is completed by manually rotating the pipe based on the support wheel.

[0040] Through testing, it is found that the ultrasonic weld detection device of the utility model can quickly realize the positioning and detection of pipeline welds in practical applications.

[0041] Example 2

[0042] Refer to Example 1, except that the detector 5 includes a camera for obtaining the weld position on the pipe.

[0043] It has been found that the ultrasonic weld detection device of the utility model can more quickly locate and detect pipeline welds in actual applications.

[0044] Example 3

[0045] Refer to Example 2 for implementation, but the difference is that it also includes a rotating mechanism for driving the pipe to rotate, the rotating mechanism is a rotating clamp, and the base of the rotating clamp is installed on the second slide rail 6 of the pipe moving and positioning mechanism.

[0046] In actual application, after the pipeline weld moves to the bottom of the detector 5, the position of the rotary clamp is adjusted by the second slide rail 6, and then the pipe is clamped by the rotary clamp and rotated to realize the detection of the weld. When the pipe is large, rotary clamps can also be set at both ends of the second slide rail 6 to ensure stability.

[0047] After testing, it was found that the ultrasonic weld detection device described in the utility model can further effectively improve the detection efficiency of pipe welds when used in actual applications compared with the solution in Example 2.

[0048] The ultrasonic weld detection device provided by the utility model can realize rapid positioning and detection of pipe welds in practical applications through the joint action of a horizontal moving positioning mechanism, a vertical moving positioning mechanism, a pipe moving positioning mechanism and a detector, and is particularly suitable for rapid detection of batch pipe welds.
