It wipes, damage built-up welding pipeline can be prevented；Position between castor and adjustment axis can be adjusted, and can be adapted for the straight of different inner diameters
Pipe detects.But the internal diameter of straight tube may have certain deviation at different length, be finely tuned between castor and adjustment axis by spring
Position, can prevent castor from meeting with obstruction can not advance or damage by pressure straight tube inner wall.
Description of the drawings
Fig. 1 is the utility model position view.
Fig. 2 is 1 schematic diagram of the utility model embodiment.
Fig. 3 is 2 schematic diagram of the utility model embodiment.
Wherein 1 is support connecting frame, and 2 be adjustment axis, and 3 be compressed spring, and 4 be trundle bracket, and 5 be castor, and 7 be nut.
Specific embodiment
As shown in Figure 1, a kind of built-up welding straight tube inner wall PT detection device adjustable supports, connecting rod 8 is stretched into inside straight tube, connection
8 end of bar sets nozzle 10 and endoscope 9, and 8 end of connecting rod and centre position set adjustable support respectively, castor 5 with
Straight tube inner wall contacts.When straight tube is not too long, 8 end of connecting rod sets a set of adjustable support；When straight tube is longer, connecting rod
8 centre positions can set several adjustable supports.
Embodiment 1.
As shown in Fig. 2, adjustable support, including support connecting frame 1, support connecting frame 1 is along connecting rod 8 circumferentially disposed four
Threaded hole sets four adjustment axis 2 on support connecting frame 1, is threaded in adjustment axis 2, adjustment axis 2 is close to the one of connecting rod 8
End locks connecting rod 8 by connecting compression connecting rod 8 with 1 upper screwed hole of support connecting frame；1 upper edge connecting shaft of support connecting frame
8 circumferential uniformly 2 adjustment axis 2 can compress connecting rod 8, the compression connecting rod 8 that 3 adjustment axis 2 of setting can be stablized.It adjusts
The other end of the axis 2 far from connecting rod 8 sets trundle bracket 4, and hole, trundle bracket 4 and adjustment axis 2 are threaded on trundle bracket 4
It is connected through a screw thread, castor 5 is set on trundle bracket 4.
When it is implemented, adjustment axis 2 is first passed through close to one end of connecting rod 8 and the screw thread of 1 upper screwed hole of support connecting frame
Connection compresses connecting rod 8；Then the straight tube internal diameter detected as needed, by adjusting the spiral shell between trundle bracket 4 and adjustment axis 2
Line connects the position for adjusting castor 5.Connecting rod 8 drives at least one adjustable support to enter straight tube, and castor 5 is contacted with straight tube
Supporting linkage 8.
Embodiment 2.
As shown in figure 3,2 difference from Example 1 of embodiment is：4 bottom of trundle bracket sets through-hole, through-hole diameter
Slightly larger than the diameter of adjustment axis 2, trundle bracket 4 is sleeved on by its bottom through-hole above adjustment axis 2；4 bottom of trundle bracket and branch
