Abstract

PURPOSE:To make it possible to make remote operation even in off-center arranged riser cylindrical piping by setting several centering adjusting nozzles radially in a suspended centering device used for repairs inside of a cylindrical tube, and performing the centering by spouting fluid from the nozzles. CONSTITUTION:Fluid 70 pressurized by a compression pump flows through a flexible tube 30, and spouts from a blow-off opening, as it is pressing the inner surface of the wall of a centering adjusting nozzle 20. This spouted fluid 70 runs against the wall surface 50 of a cylinder directly, reverses, and flows into a space between the cylinder wall and the outer surface of the wall of the said nozzle 20, as it is pressing the outer surface of the wall of the said nozzle 20. Because fluid 70 flows from several centering adjusting nozzles 20 at the same time, the centering of the suspended machine tool 60 can be performed.

ON1, while pressing the inner wall direction of the centering adjustment nozzle 20, it is ejected from the outlet. The ejected fluid 70 directly hits the cylindrical wall surface 50 and is reversed, pushing the outer wall surface of the centering adjustment nozzle and being discharged into the gap between the cylindrical wall and the outer wall surface of the centering adjustment nozzle. This centering adjustment nozzle is composed of several units so that V@ can be adjusted freely according to the diameter of the target cylindrical pipe, and each unit can move simultaneously, so this device The center of the body of is the center of the cylindrical wall.

ことができる。FIG. 2(a) shows a case where there is one main body 11 of the centering device, and FIG. 2(b) shows a case where there are two main bodies 11 of the centering device. The two main bodies 11 include a working device 60 and a lower main body 1.
They are connected by a flexible tube 31 that carries the weight of the two parts and guides pressurized fluid. By combining the two main bodies, the operation of the working equipment 60 (d) becomes more stable than when one main body is used. Also, since the lower main body is also connected with the flexible tube 31, the eccentric tube can be prevented. It can be moved easily even when passing parts.

る。FIG. 3 shows an example of the structure of the centering adjustment nozzle on the X flow side of the centering device. Looking at one unit of centering adjustment nozzles, pressurized fluid enters the main body upper chamber 28 through the flexible tube 30, and from there flows into the nozzle frame 21 of each unit via the freely expandable and contractible tube 29'tA. Ru. This inflowing fluid pushes the nozzle frame 21 and blows out through the outlet 22.

外側に同距離だけ動かすことになる。A rubber-like nozzle cover is attached to the tip of this outlet, and since the ejected fluid once stagnates before being discharged, it is possible to prevent contact between the nozzle frame and the cylindrical wall.
Also, the number of fluid types can be reduced. Even when one nozzle frame 21 is pushed out by the fluid, the rods 24 connected to the top and bottom of the nozzle frame 21 move outward,
The rack 25 attached to the center side of the main body frame rotates the pinion 26, and the racks 25 of other units holding it move outward, moving all the nozzle frames 21 outward by the same distance at the same time.

る。FIG. 4 shows an example of the structure of another nozzle for centering adjustment. When the nozzle outer frame 27 of the L unit of the nozzle for centering adjustment is pushed out, the pin 15 connected to the nozzle outer frame moves on the guide part of the main body frame 12, and this movement causes the rod 14 and the main body frame pin to move. 13 and moves the main body frame 12. Due to this movement of the main body frame 12, the other nozzle units also move simultaneously, and all the units are pushed out uniformly.
