Preferably, the bearing is a ball bearing; the shaft is provided with threads at two ends, and the diameter of the middle part of the shaft is larger than that of the parts with threads at two ends; the ball bearings are arranged at two ends of the shaft to form the bearing group; and two ends of the connecting sheet are respectively provided with a through hole, and the through holes are sleeved at the shaft end part of the bearing group.

Preferably, the number of the bearing sets is increased or decreased according to the pipe diameter of the pipeline to be detected.

Preferably, the probe is a phased array ultrasound probe.

Preferably, the probe clamping plate is provided with a notch, and the probe clamping plate is connected with the connecting sheet of the bearing group in a clamping manner through the notch.

The utility model discloses the quantity of bearing group is increased and decreased according to the diameter difference of detection pipeline, replaces a set of connection piece messenger bearing group with two springs at last and links into cyclic annular to the contractile force through the spring makes this cyclic annular bearing group can tightly paste the outer wall at the detection pipeline.

The utility model discloses simple to operate can replace a set of connection piece through the spring through the connection piece with the bearing group link into the chain form, at last, becomes the chain form bearing group link ring-type to paste tightly at the pipeline outer wall. After the probe and the probe clamping plate are fixed, the probe and the probe clamping plate are stably clamped on the two groups of connecting plates, so that the rotation of the annular bearing group can be realized, the probe is driven to rotate along the circumferential direction of the pipeline, and the disposable whole-volume detection and covering of the annular welding line of the pipeline are realized. The detection scanner can be repeatedly used, and compared with the prior art, the detection scanner has the following advantages and positive effects:

1. the bearing ring is connected by a plurality of bearings and is formed, and the rotation resistance is little, makes the probe more in the same direction as smooth along the removal of pipeline circumference.

2. Bearing ring passes through connection piece and spring coupling, simple to operate, and the setting up of spring makes the bearing ring laminating inseparable on the pipeline outer wall, guarantees to detect the coupling.

3. Every bearing group all can be dismantled or increase, can increase and decrease according to the size that detects the pipeline diameter, can use with the pipeline detection of different pipe diameters.

4. The probe is phased array probe, and phased array probe transmission ultrasonic wave can realize once sweeping and check, detects whole pipeline hoop welding seam.

5. Probe splint pass through two breach cards on the connecting piece to the realization is connected with the bearing ring, simple to operate, connects stably.
