Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for fixing and removing the entire or part of an industrial endoscope insertion portion to an object made of a magnetic material, such as the inner wall of a chemical plant equipment tatami pipe. #cs This invention relates to an industrial endoscope insertion part fixing device that allows the endoscope insertion part to be easily fixed and removed without impairing the functions of the industrial endoscope.

Il! with an industrial endoscope! When performing various operations such as inspection, inspection, collection, treatment, etc., it is necessary to fix the insertion section to work object #C in order to perform the operations more accurately and reliably.

Conventionally, this woodcutter's fixing device was a real m.48
A structure shown in FIGS. 1 to 4 of Japanese Patent No. 26760 is used.

This kind of fixing device shown in Fig. 1 is attached to a suction cup 2'lk with a circumference of 8Ka'tA on the distal end portion 1 of the endoscope, and the fixing device shown in Fig. 2 is a suction cup 2'lk shown in Fig. Magnets 3 are attached to several places on the concave surface of the board 2 so that the magnets can be fixed by 1: more than the magnet IK.

The fixing device shown in Figure 3 is the concave suction cup 2 described in Figure 1.
Two parts JVRK light guide 4 and fiber scope 5
The fixing device shown in Fig. 4 has an electromagnetic impact ring (PI-shaped) at the tip of the light guide 4 of the insertion section.
This is then inserted and fixed into the object to be worked on.

However, in certain devices such as those described above, #! 1wA
If a concave first mounting plate 2 as shown in Fig. 1 is used, the device for fixing the endoscope itself will heat up, the original function of the endoscope will deteriorate, and it will be inconvenient when inserting and fixing the endoscope. -becomes.

In addition, when an electromagnet 6 is installed around the endoscope as shown in Figure 4, the endoscope insertion part is usually small, so the above-mentioned electromagnet attached to it only has the function of fixing it firmly enough. It is difficult to provide such an electromagnetic force, and since an electromagnet is provided in a part of the insertion portion, the mechanism (for electrical connection) at the tip of the insertion portion is complicated.

This generation Ij11 was created in consideration of the above points, and a magnetic material with high magnetic permeability is provided in the insertion portion.

By installing a magnetization device that can generate and eliminate magnetization on workpieces made of magnetic materials, it is possible to attach industrial objects to the desired part of the workpiece without reducing the functionality of the endoscope. With the goal.

Please refer to the drawings below to understand this invention! Be brave.

Figures 1 and 6 show a first embodiment, which is constructed and operated as follows.

The insertion part 11 has a tip part 12, a curved part 13, and a flexible part 14.
In an industrial endoscope, the irises are made of a paramagnetic material or ferromagnetic material with high magnetic permeability, which is magnetized by a magnetic field, and when the magnetic field disappears, the magnetization almost disappears. A magnetic body (piece) formed from a substance, etc.
In the case where #l is formed to include s, FIG. 6 shows the insertion part 11
The outer skin 11 The entire inner side is a magnetic material (piece) 15 similar to the above.
This is the case when the configuration is configured to include.

The magnetic material (piece) No. 1 may of course be a mixture of a paramagnetic material and a ferromagnetic material, and if it contains a ferromagnetic material, a material with less hysteresis characteristics is desirable.

In addition, when the magnetic material 16 is provided at the tip 12 as shown in No.
As shown in the enlarged cross-sectional view of 5.1. ``C4h'' is good, or as shown in the enlarged cross-sectional view of the same figure (q), it is also possible to provide 5K so that it has a cylindrical shape around the entire circumference of the tip s11.

The above can be applied to the 536 diagram as well.

On the other hand, a circumferential sec coil or the like of a magnetic material with high magnetic permeability is formed outside the work object 16, such as a vibrator made of a magnetic material that is magnetized by a magnetic field, and a current from a power source is passed through this coil to generate a magnetic field. By magnetizing the workpiece 16 and the magnetomotive body 1&, they are mutually connected! A magnetizing device 57 is provided for pulling the tip s12 and fixing it.

In addition, this magnetizing device 11 can almost eliminate the magnetic field by cutting off the current, so that the magnetic material 1s provided at the tip 12K of the endoscope and the object 16 to be worked on can be brought into contact with each other. It is constructed in such a way that it can be easily removed by substantially eliminating the magnetization (due to the attractive force).

To explain the operation of the first embodiment configured as described above, the endoscope tip 12 is inserted into the workpiece 16,
installed at the site to be observed, while an external magnetization device 1
The magnetic material 1& provided on the work object 16 and the tip 12 through the electric current passed through the endoscope tip 12 at a predetermined portion of the wall of the work object 160 as shown in the CSS diagram and FIG. is fixed by suction. Therefore, functions such as endoscopic observation can be performed in this state.

When removing the endoscope after completing functions such as observation.

Alternatively, when observing other parts, the magnetic field almost disappears by turning off the power to one magnetizing device, and the insertion part 1
Since the magnetic body 15 provided in the workpiece 1 can be freely separated from the workpiece 1, it can be removed or further set again.

Note that the magnetization device 11 is not limited to the position shown in FIG.
5111: A closer position is somewhat more advantageous for the fixing function. Depending on the case, the magnetizing device 17 can also be installed inside the workpiece 16. ! : Since the size of the magnetizing function can be adjusted from K, the required fixing strength can be easily achieved.

The second embodiment shown in FIGS. 1 and 8 is an embodiment in which the magnetic material 15 or the soft material s14 in the first embodiment #C is provided only partially or over the entire area.

Therefore, in this case as well, it can be fixed to and removed from the workpiece 16 in substantially the same manner as described above.

In this embodiment, the magnetic body 15 is the soft part 14Kwk.
When this part is fixed using one magnetizing device, the tip part 12 and the curved part 13 are not fixed as shown in 9, so by bending the curved part 13, the area around the fixed position can be fixed. Observed and collected over a wide range6
You will be able to move to Okigo.

In the first and second embodiments described above, the magnetic material 15 is housed inside the outer skin tta of the insertion portion 11, but in the third embodiment shown in FIG. In the illustrated example, the magnetic body 15 is attached to a part of the soft part 14, almost the same as that shown in FIG. It is not limited to this.

The magnetic body 15 in this embodiment is, for example, as shown in FIG. 9 (J3).
As shown in the enlarged cross-sectional view, a part of the cylindrical shape is cut out, and the soft part 14 is brought into contact with this notch, and the soft part 14 side (suppressed and the magnetic body 1s is pressed inside the soft part 14). By inserting the magnetic body 15 into the insertion portion 11, the fixing magnetic body 15 can be fixedly attached to a desired position of the insertion portion 11, and by performing the reverse operation, it can be removed and used as an ordinary industrial endoscope.

Therefore, according to this embodiment, the magnetic body 1b is inserted into the insertion portion 11.
Since it can be attached and detached to any desired position, its advantage is that it can be used for any purpose in an ordinary industrial endoscope. When this magnetic body 1b is attached, the fixing to the work object 16 and the operation for removing the printing plate are the same as described above.

Although the magnetic bodies 1 & I) # shape in each of the above-mentioned embodiments are shown to have a simple structure, they are not limited to the above-mentioned shapes as long as they have the function of fixing the magnetization by the magnetization device 17. - and its dimensions are insert 911 F
In the case of accommodating 3 K, the shape depends on the dimensions of the insertion portion 110, but when it is provided on the outer periphery S of the insertion part 1111, the shape is not limited to the shape shown in FIG. 189, but other shapes may be used.

Each of the embodiments described above is a case in which one magnetic body 1s is provided, but the present invention is not limited to this, and a large number of magnetic bodies 15 may be provided to simultaneously fix a plurality of desired fixing positions.

Note that even if the workpiece 16 does not have a pipe-like shape as shown in the figure, it can be magnetized by the magnetization device 17K, so it goes without saying that this method can also be applied.

Furthermore, when the magnetic body 15 is provided inside the insertion section 11, if it is incorporated as a part of the component, rather than being specifically incorporated for fixation, the external shape of the insertion section 11 can be made small so as not to be bulky. Part materials can be reduced.

As stated above, according to the present invention, the magnetic material (
Since the workpiece is made of magnetic material and is equipped with a magnetization device that can generate and eliminate IK magnetization, the tip of the insertion tube can be used as the workpiece without deteriorating the function of the endoscope. Insert the object to the desired position and observe.

Suitable for functions such as collection and treatment, it can be easily fixed and removed, and since a magnetization device is used, the external shape of the magnetic material provided at the insertion site does not need to be set large as desired. It has the advantage of being able to be firmly fixed in place.
