Crack searchlighting can not just be carried out by putting, and extension rod is set in the one end of support arm away from clamping head, when the diameter of detection pipes is more than support
Can be solved during arm lengths by extension rod due to support it is too short caused by can not searchlighting the problem of, so as to reach that increase is visited
Survey the effect of diameter.
It is preferred that, the rubber roll for being used for being rolled in pipeline is provided with support arm.
By above-mentioned technical proposal, during clamping head is toward weld motion, clamping limb can enter with the inwall of pipeline
Row friction, such workman can be very laborious during pushing inward, can cause support arm serious wear, so as to reduce support
The service life of arm, sets the rubber roll that can be rolled on support arm, and workman can be made to promote installation body toward welding
Place can also extend the service life of connecting rod when sending with laborsaving.
It is preferred that, fixed part includes compressing piece, and the two ends for compressing piece are fixed on clamping head by screw, and photohead is located at
Compress in the middle part of piece.
By above-mentioned technical proposal, photohead is fixed on clamping head with piece is compressed, it is ensured that workpiece is moved in pipeline
It is steady in dynamic process, and with screw come the piece that is fixed and clamped, fastening is reliable, and the cost of screw is low, with screw come tight
The tight piece of solid pressure is also convenient for the dismounting of photohead, so as to reduce production cost, improves the efficiency of detection.
It is preferred that, the screw that clamping head is provided with the arc groove compression piece for being used for laying photohead is located at arc groove
Both sides.
By above-mentioned technical proposal, due to having inclined-plane on clamping head, when photohead is fixed on inclined-plane, toward weldering in pipeline
When being moved at seam, photohead may be slid from clamping head, and arc groove is set on clamping head, can preferably make photohead
It is fitted on installation body, the screw on tight piece is located at the both sides of arc groove, it is ensured that clamping head is moved through in pipeline
Photohead keeps fastening in journey；Arc groove is designed with the mounting blocks at two ends so when detecting distance is long, Ke Yiyi
Photohead is moved to the arc groove of close commissure, so that shorten photohead and need the distance of weld detected, so that
Up to the efficiency for improving detection.
It is preferred that, on the excircle of clamping head, groove is provided with close to the end of photohead side, is connected with groove
The handspike for promoting clamping head to move back and forth in pipeline.
By above-mentioned technical proposal, because the weld seam for needing to detect is in pipeline, clamping head is difficult the position for reaching detection,
One handspike is set on clamping head, can facilitate personnel that clamping head is sent to the commissure for needing to detect, facilitate counterincision
The detection of seam, and taking-up in the nose heave pipeline of clamping has been also convenient for, so as to improve the efficiency of detection.
Compared with prior art, the beneficial effects of the utility model are：Support arm movable back and forth can be against in pipeline
On wall, and extension rod can be increased on supporting arm when the length of support arm is less than the diameter of pipeline, had on extension rod
There can be the handspike for making clamping device move back and forth in pipeline on clamping head in the movable rubber roll of inner-walls of duct；
Additionally, due to this scheme need not by support arm regulation to identical with pipeline aperture, can elder generation's adjusting screw to the pressure of support arm
Clamping device, is then directly put into pipeline by tightness so that have pretightning force on support arm and can rotate, then by turning
The dynamic support arm being hinged on clamping head, makes support arm to be against on inner-walls of duct, so this scheme also saves the time, improves
The efficiency of detection.
