Description

A kind of spiral welded pipe weld seam probe frame

Technical field

The present invention relates to the ultrasonic flaw detection field, relate in particular to a kind of spiral welded pipe weld seam probe frame.

Background technology

Adopting automatic ultrasonic inspection at present is to check and the very cost-effective means of control spiral submerged welded pipe weldquality, also be that each important pipeline is produced necessary detection means in recent years, the principle of spiral pipe automatic flaw detection is that the symmetria bilateralis at spatially spiral curve weld seam is provided with two row's weld seam probes, weld seam probe emission ultrasound wave, ultrasound wave runs into the interior defect reflection of steel pipe and returns, receive by this probe or other probes, signal is after control system analysis, depict defect shape, all weld seam probes all are installed on the weld seam probe frame, probe holder is in the control lower edge of seam tracking system weld movement, in the automatic flaw detection process in order to guarantee that weld seam probe all drops on the steel pipe, accurately make up with outer wall of steel pipe, weld seam probe frame is designed to space plate shape or bar linkage structure more, when spiral pipe diameter and wall thickness change, adjust distance and lifting angle between the probe, the structure of weld seam probe frame can only be made simple distance adjustment at present, therefore probe and outer wall of steel pipe can not guarantee to make up fully, thereby strengthen the flaw detection error, and be difficult to eliminate.

Summary of the invention

The objective of the invention is at the problems referred to above, a kind of spiral welded pipe weld seam probe frame is provided, can adjust distance and lifting angle between the probe flexibly, make probe and weld seam can guarantee to make up fully, reduce the flaw detection error.

For achieving the above object, the present invention is achieved through the following technical solutions:

A kind of spiral welded pipe weld seam probe frame, comprise rigidity main shaft, principal axis of compliance, fixedly wing plate, swing wing plate, rigidity main shaft and principal axis of compliance be arranged in parallel up and down, a plurality of fixedly wing plates are serially connected on the rigidity main shaft successively, principal axis of compliance is formed by connecting from beginning to end by a plurality of main shafts joint, a pair of swing wing plate is set on each main shaft joint, main shaft joint and fixedly regulate leading screw by radian between wing plate, the rigidity main shaft and link together, the swing wing plate is arranged on fixedly the wing plate below, swings the wing plate end and is connected by haulage gear with fixing wing plate end.

Described swing wing plate comprises swing arm, probe sound path control hand wheel, universal probe socket, and the swing arm end is provided with probe sound path control hand wheel, and probe sound path control hand wheel is connected with universal probe socket by screw rod, and universal probe socket slides along the swing arm downside.

Described haulage gear comprises the cylinder that rises and falls, the control hand wheel that rises and falls, lead, the cylinder that rises and falls is arranged on fixed-wing profile material inside, the cylinder bar links to each other with lead one end, the lead other end links to each other with swing wing plate end, and the control hand wheel that rises and falls of regulating the position of cylinder in the fixed-wing profile material of rising and falling is arranged on fixedly wing plate end.

Compared with prior art, the invention has the beneficial effects as follows: 1) adopt principal axis of compliance, make probe and weld seam can guarantee to make up fully, reduce the flaw detection error; 2) rigidity main shaft and principal axis of compliance are be arranged in parallel up and down, simple in structure, adjust dimensionally stable; 3) radian of principal axis of compliance is regulated the leading screw manual adjustments by radian, and setting range is big, adjusts flexibly; 4) this structure is fit to many probes form, can improve the defective recall rate greatly.
