Description

Technical Field

[0001] This utility model relates to the field of metal pipe inspection technology, and specifically to a device for inspecting the outer wall of metal pipes. Background Technology

[0002] In engineering inspection, manual ultrasonic metal detectors are usually used to inspect metal pipes. Manual ultrasonic metal detectors are generally used to inspect the thickness, cracks, slag inclusions, and porosity of metal pipes. When inspecting the outer circumference of the pipe, the detection probe needs to be pointed towards the metal pipe and then rotated around the axis of the metal pipe for inspection.

[0003] In the prior art, the metal pipe needs to be fixed and the detection device needs to be installed on a rotatable structure. When the pipe is being detected, the clamping device blocks most of the area at both ends of the metal pipe. The rotating detection device needs to be powered by a battery and a wireless information transmission module needs to be installed, which makes the work efficiency low. Therefore, this device provides a metal pipe outer wall detection device. Utility Model Content

[0009] As a further improvement to the above solution, a second motor is fixedly installed on one side of the mounting box, and a bidirectional lead screw is fixedly installed at the output end of the second motor. The moving plate is threadedly installed on the left and right sides of the outer side of the bidirectional lead screw.

[0010] As a further improvement to the above solution, a knob is fixedly installed on the outer side of one end of the first unidirectional lead screw, a limit groove is opened on one side of the clamping frame, and the movable abutment block is slidably installed on the inner side of the limit groove.

[0011] As a further improvement to the above solution, a first electric telescopic rod is fixedly installed on the top inner wall of the mounting frame, a fixed box is fixedly installed at the output end of the first electric telescopic rod, a fourth motor is fixedly installed on one side of the fixed box, and a second unidirectional lead screw is fixedly installed at the output end of the fixed box.

The bidirectional screw can drive the movable plates on both sides to move in opposite directions through the threaded engagement, and let the fixed abutment block and the movable abutment block slide into the inside of the metal pipe. Control the knob to drive the first unidirectional screw to rotate. The first unidirectional screw can drive the movable abutment block to move through the threaded engagement, so that the fixed abutment block and the movable abutment block are pressed against the inner wall of the metal pipe, so that the outer wall of the metal pipe will not be blocked during the inspection process.

[0016] Second, during the testing process, the third motor can be controlled to drive the movable shaft and the clamped pipe to rotate, and the fourth motor can be controlled to drive the second one-way lead screw to rotate.
