Description

Technical Field

[0001] The invention relates to the field of detection technology, and in particular to a multi-channel probe type welded pipe internal burr detection device. Background Art

[0002] During the production process of high-frequency welded pipes, welding extrusion will produce a longitudinal burr on the inner wall of the pipe, which needs to be removed with tools. This process is carried out inside the steel pipe, and the removal status and quality cannot be observed in real time. It can only be observed after the steel pipe is cut to a fixed length, which will affect the quality and cost of the product. Existing inspection methods such as imaging and ultrasonic methods are affected by factors such as high-frequency electromagnetic interference or large investment in detection equipment, and cannot be effectively and widely used on high-frequency welded pipes. Based on this, the present invention proposes a multi-channel probe-type welded pipe burr detection device, which avoids the interference of high-frequency electronics and high-frequency heating, and can effectively monitor the removal of burrs in welded pipes online, achieving accurate, real-time, efficient, sensitive and convenient effects.

[0028] like Figure 1-5 As shown, a multi-channel probe type welded pipe burr detection device includes a detection box 9, a multi-channel probe assembly component 8 is installed inside the detection box 9, and the top probe 1 of the multi-channel probe assembly component 8 is against the welded pipe burr 6 on the inner wall of the pipe 7.

[0029] The multi-channel probe assembly component 8 includes a plurality of position output slide plates 3 slidably mounted on the inner bottom end of the detection box 9, which can only slide forward and backward, and transmit the position signal to the outside of the pipe through the extension of the thin wire, so as to provide observation for operators and inspectors. One end of the position output slide plate 3 is slidably connected to the size enlargement connecting rod 2 distributed obliquely upward, and the other end is connected to the thin wire; the other end of the size enlargement connecting rod 2 is slidably connected to the probe 1 distributed obliquely upward, and the probe shaft 5 is hingedly connected to the center position of the probe 1, and the connecting rod shaft 4 is hingedly connected to the center position of the size enlargement connecting rod 2. The two ends of the connecting rod shaft 4 and the probe shaft 5 are fixedly mounted on the inner wall of the detection box 9. The position signal detected by the probe 1 and the size enlargement connecting rod 2 is amplified by the cylinder rod principle, and the thin sheet probe 1 detects the height of the burr 6 in the welded pipe, which is not affected by welding nodules, high temperature and cooling water.

[0030] The probe 1 includes a probe body 101 , and a slot 102 is formed at the lower end of the probe body 101 ; the position output slide plate 3 includes a slide plate body 301 , and a slot 2 302 is formed at the front end of the slide plate body 301 .

[0031] The enlarged connecting rod 2 comprises a connecting rod body 201, the upper end of which is mounted with a sliding post 202 matching with the slot hole 102, and the lower end of which is mounted with a sliding post 203 matching with the slot hole 2 302. The slot hole 102 and the slot hole 2 302 are both long through hole structures.

[0032] The end of the probe 1 away from the size enlargement connecting rod 2 is in an arc-shaped structure, which effectively prevents the irregularity and unevenness of the internal burrs from impacting the device and affecting the monitoring effect.

[0033] The plurality of probes 1 are closely fitted together to prevent welding slag from falling into the gaps and affecting monitoring. At the same time, they are positioned and supported by each other, and there is no interference between the channels.

[0034] The detection box 9 is a closed structure, which effectively prevents welding slag after welding from entering the device and affecting the effective operation of the probe mechanism.

[0035] The detection box 9 includes an integrally formed side panel, a bottom panel and a front cover panel, a positioning pin 11 is installed on the inner wall of the side panel, and the other end of the positioning pin 11 can be plugged with a detection box cover panel 10, and the detection box cover panel 10 matches the side panel; the tail of the side panel and the detection box cover panel 10 is installed with a detection box installation tail plate 12 that matches the front cover panel.

[0036] The front cover plate is provided with a hole for the multi-channel probe assembly component 8 to pass through.

[0037] The action process of the present invention is as follows:

[0038] First, the device moves behind the internal burr removal mechanism. When the probe 1 passes through the internal burr 6 of the welded pipe, the probe 1 is pressed down, and the connected size enlargement connecting rod 2 rotates counterclockwise through the cooperation of the slot hole 102 and the slide column 1 202. The other end of the size enlargement connecting rod 2 cooperates with the slot hole 302 on the position output slide plate 3 through the slide column 203, so that the slot hole 302 slides to the right. The signal of the position output slide plate 3 moving to the right is converted into a shortening signal of the thin line and transmitted to the outside of the steel pipe.

[0039] Then, when the burrs are removed and flushed, the position output slide plate 3 moves to the left under the pulling force of the thin wire, driving the size enlargement connecting rod 2 to rotate clockwise, and the probe 1 rebounds upward and is close to the pipe wall where the burrs are removed. The signal of the position output slide plate 3 moving to the left is converted into an elongation signal of the thin wire and transmitted to the outside of the steel pipe;

[0040] Finally, if the scraping is too deep, the probe 1 will be lifted, driving the size enlargement connecting rod 2 to rotate clockwise, and the signal of the position output slide plate 3 moving to the left is converted into a signal of the elongation of the thin line and transmitted to the outside of the steel pipe.

[0041] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
