Description

Technical Field

[0001] The utility model belongs to the technical field of magnetic powder detection coil method, and particularly relates to a detection device of magnetic powder detection coil method. Background Art

[0002] At present, the mainstream application devices of magnetic particle detection coil method technology are cables (cable winding method) and solenoid coils. However, for products such as boiler headers, there are often many corner welds, narrow gaps, and positioning plates on the pipe ends, which makes the solenoid coils unusable. The cable winding method for each corner weld is inefficient, uneconomical, and affects the detection cycle. At the same time, for the corner welds of this type of product, due to the small diameter of the pipe (generally less than Φ89mm), the yoke method technology cannot meet the magnetization requirements in one direction due to poor contact; if the contact method technology is used, the operation is cumbersome and easy to burn the workpiece. Utility Model Content

[0003] In order to solve the above problems existing in the prior art, the purpose of the utility model is to provide a magnetic powder detection coil method detection device which is convenient and fast to use.

[0004] The technical solution adopted by the utility model is:

[0006] The left conductor and the right conductor of the same group are insulated by an annular insulating gasket, and the left conductor and the right conductor of the same group are only conductive through the overlapping parts, and the adjacent groups of conductor components are conductive through the hollow conductive connecting columns, so that the detection device forms a spiral conductive structure.

[0007] The utility model is designed with detachable components (conveniently assembled according to the required magnetization specifications, and the size and length of the spiral tube can be changed) and a coil structure that can be opened and closed. Through the control of the operator, the coil can be opened and moved so that the object to be inspected (such as the corner weld pipe seat, etc.) is located inside the coil and then the coil is closed, which conveniently achieves an effect similar to using a cable to wrap around the workpiece or making the workpiece located in the spiral coil, thereby realizing longitudinal magnetization. The utility model solves the problem that the existing coil method technology is inefficient and difficult to operate when applied to the inspection of such products. The utility model solves the problem that when the yoke method technology is used to inspect such structures, there is poor contact in one direction, and when the contact method technology is used to inspect, the workpiece is easily burned and the efficiency is low. The utility model combines other technologies to achieve 100% magnetic particle inspection of such product structures.

[0008] As a preferred solution of the utility model, it also includes a snap plate, which is respectively connected to all left conductors or all right conductors, and an opening and closing assembly is connected to the snap plate.

[0009] As a preferred solution of the utility model, a connecting ring is connected to the buckle plate, and the left conductor or the right conductor is sleeved in the connecting ring. The connecting ring is connected to the left conductor or the right conductor, so that when the opening and closing assembly pulls the buckle plate, the connecting ring can drive the left conductor or the right conductor to rotate.

[0010] As a preferred solution of the utility model, the opening and closing assembly is connected to the middle section of the buckle plate. The opening and closing assembly pulls the buckle plate from the middle, which is more labor-saving.

[0011] As a preferred solution of the utility model, the opening and closing assembly includes an opening and closing rod, a connecting ear is fixed on the buckle plate, and the opening and closing rod is rotatably connected to the connecting ear. The opening and closing rod can push and pull the buckle plate, which is easy to operate.

[0012] As a preferred solution of the utility model, the number of the snap plates and the opening and closing components are both two, one of which is connected to the left conductor, and the other is connected to all the right conductors.

[0013] As a preferred embodiment of the utility model, one end of the left conductor connected to the insulating guide pillar and one end of the right conductor connected to the insulating guide pillar are both provided with half-cut grooves, the half-cut grooves of the left conductor and the half-cut grooves of the right conductor are spliced ​​together, and an annular insulating gasket is arranged between the half-cut grooves of the left conductor and the half-cut grooves of the right conductor.

[0014] As a preferred solution of the utility model, the relative positions of the left conductor and the right conductor in the plurality of conductor assemblies are the same, ensuring that the detection device forms a spiral conductive structure.

[0015] As a preferred solution of the utility model, the end of the left conductor away from the insulating guide pillar is provided with a concave surface, and the end of the right conductor away from the insulating guide pillar is provided with a convex surface, and the concave surface of the left conductor and the convex surface of the right conductor in the same group are engaged. Through the engagement of the convex surface and the concave surface, reliable conduction can be ensured at the overlap of the left conductor and the right conductor.

[0016] As a preferred solution of the utility model, the shapes of the left conductor and the right conductor are both semicircular. The left conductor and the right conductor are combined into a full circle, which is convenient for setting the structure to be detected inside.

[0017] The beneficial effects of the utility model are:

[0018] Compared with the traditional cable winding method and solenoid coil device, the utility model adopts a coil structure scheme with detachable components and openable and closed operations. The coil can be opened, moved, and closed by the operator, which greatly improves the detection efficiency and conveniently realizes the detection effect of using a cable to wind the workpiece or placing the workpiece in the solenoid coil. Especially for some special structures and situations, such as when there are many fillet welds, narrow gaps, and positioning plates on the pipe ends, the device can conveniently realize coil method detection.
