[0022] By installing a fixing seat 10 and a ball 11 on the outer walls of bracket No. 1, bracket No. 3, bracket No. 4, 13, and bracket No. 2, 3, when it is necessary to perform a forward and backward rolling test on the outer wall of the steel pipe, it is only necessary to push the push rod 2. Under the action of the push rod 2, the entire device can be moved forward and backward on the outer wall of the pipe to be tested 14, and the outer wall of the pipe to be tested 14 can be detected under the action of the detection probe 9.

[0023] In a preferred embodiment: a square groove is formed in the inner cavity of the No. 1 bracket 1 , and the shape and size of the inner wall of the square groove matches the shape and size of the outer wall of the adjustment plate 4 .

[0024] By opening a square groove in the inner cavity of the No. 1 bracket 1, when testing the tubes 14 to be tested of different diameters, the overall size of the device can be adjusted by adjusting the depth of the adjustment plate 4 entering the inner cavity of the No. 1 bracket 1 and the depth of the adjustment plate 4 entering the inner cavity of the No. 2 bracket 3, so that the device can match the tubes 14 to be tested of different diameters for testing.

[0025] In a preferred embodiment, two ends of the outer wall of the driving spring 7 are in contact with the inner wall of the supporting plate 5 and the outer wall of the limiting plate 8 respectively, and the driving spring 7 is made of high carbon steel.

[0026] By means of the driving spring 7 arranged on the outer wall of the pull rod 6, the pull rod 6 can enter the inner cavity of the adjustment plate 4 under the action of the driving spring 7 and the support plate 5, thereby locking the adjustment plate 4. At this time, the outer wall of the ball 11 can contact the outer wall of the tube to be tested 14, so that the detection probe 9 can better detect the outer wall of the tube to be tested 14.

[0027] In a preferred embodiment, the ball 11 is rollingly connected to the inner cavity of the fixing seat 10 , a limiting hole is provided on the outer wall of the adjustment plate 4 , and the inner wall diameter of the limiting hole matches the outer wall diameter of the pull rod 6 .

[0028] By rolling the ball 11 connected in the inner cavity of the fixed seat 10, the device can slide back and forth on the outer wall of the tube 14 to be tested under the action of the ball 11, which is more convenient. The limiting hole opened on the outer wall of the adjusting plate 4 allows the outer wall of the pull rod 6 to enter the inner cavity of the adjusting plate 4, thereby locking the adjusting plate 4.

[0029] In a preferred embodiment, there are four fixing seats 10 , and the four fixing seats 10 are respectively mounted on the outer walls of the first bracket 1 , the second bracket 3 , the third bracket 12 , and the fourth bracket 13 .

[0030] By installing four fixing seats 10, and installing balls 11 in the inner cavities of the four fixing seats 10, the whole device can be supported from four directions at the same time, so that the detection probe 9 can move more stably on the outer wall of the tube 14 to be tested.

[0031] In a preferred embodiment: a rubber buffer pad is fixedly mounted on the outer wall of the push rod 2, and the No. 1 bracket 1, the No. 2 bracket 3, the No. 3 bracket 12, and the No. 4 bracket 13 are all made of stainless steel.

[0032] By arranging a buffer pad on the outer wall of the push rod 2, the push rod 2 can be made more comfortable when held under the action of the buffer pad, and the No. 1 bracket 1 made of high-carbon steel can have better stability during use and a longer service life.

[0033] Working principle: During the use of the above-mentioned equipment, when the equipment is needed to detect the outer wall of the tube 14 to be tested, the distance between the No. 1 bracket 1 and the No. 2 bracket 3 and the No. 2 bracket 3 and the No. 3 bracket 12 is adjusted according to the diameter of the tube 14 to be tested, and the pull rod 6 is pulled. When the pull rod 6 is pulled, the driving spring 7 will be compressed under the action of the limit plate 8, so that the outer wall of the pull rod 6 comes out of the inner cavity of the adjustment plate 4, and then the position of the adjustment plate 4 can be adjusted. After the adjustment, the pull rod 6 is released, so that the outer wall of the pull rod 6 enters the inner cavity of the adjustment plate 4 again, and the adjustment plate 4 is locked. Then the equipment can be sleeved on the outer wall of the tube 14 to be tested, and the detection probe 9 is used to detect the outer wall of the tube 14 to be tested. During the detection process, the push rod 2 is held to rotate the position of the detection probe 9, which can be moved back and forth or rotated up and down, so that the detection probe 9 can more comprehensively detect the outer wall of the tube 14 to be tested, which is very convenient.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
