Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a surveillance scope mounting device.

[Conventional technology and its problems]

Generally, a scope is inserted into a part of the furnace wall to monitor the inside of various furnaces.

However, it is often difficult to accurately calculate and design the insertion position and direction of the scope in advance. For example, when monitoring the combustion status of burners in a large power generation boiler, it is necessary to insert a heat-resistant monitoring scope into the boiler wall and attach it facing the burner to be monitored. There are many water pipes running around the area, and it is often difficult to avoid them and bring the burner within sight.

Conventionally, surveillance scope mounting devices have been fixed, so the scope mounting position and direction designed in advance are different from the actual position and direction.
When discrepancies occurred, it was extremely troublesome to correct them.

[Means for solving problems]

A surveillance scope mounting device according to the present invention includes: a pair of parallel guide fixing members that are attached to a mounting surface through a fastener in abutting manner; and a pair of recesses formed by the guide fixing members and the mounting surface. It has a pair of fitting parts that fit into the groove, and when the fastener is not tightened, the fitting part slides along the concave groove and is movable in the direction along the guiding and fixing member. , and a base whose movement is regulated when the fastener is tightened; and a scope insertion hole that rotates about an axis parallel to the mounting surface and into which a direct-view monitoring scope is inserted. A swing support shaft provided with the swing support shaft; in a tightened state, the swing support shaft is fixed to the base to restrict its rotation, and in an untightened state, it is allowed to rotate and is perpendicular to the surface to which it is mounted. and an adjustment screw that enables the monitoring scope to swing in orthogonal planes.

[Effect]

While reciprocating the base along the guide and fixing member, the position within a plane parallel to the mounting surface can be adjusted.

The fasteners are then tightened to secure the base in that position.

In addition, by loosening the adjustment screw, the swinging support shaft becomes rotatable, and the monitoring scope swings in a plane perpendicular to the surface on which it is mounted, and then moves toward the object to be monitored, such as inside the furnace. , the tip of the scope can be pointed, and then by tightening the adjustment screw, the swinging of the scope can be restricted.

〔Example〕

Hereinafter, the present invention will be explained in detail based on the illustrated embodiments.

As shown in the perspective view of FIG. 1, the enlarged sectional views of main parts shown in FIGS. 2 and 5, and the plan view of FIG. A pair of parallel guide and fixing members 3, 3 are attached by fasteners 2 made of bolts, and the mounting positions in directions A and B along the guide and fixing members 3, 3 are adjustable. 3, and a base 4 that is fixed to the mounting surface P by the guiding and fixing members 3, 3, and a plane Q on which the monitoring scope 1 is mounted and perpendicular to the mounting surface P (see FIG. 3). A mounting position adjustment mechanism R is provided, which includes a tilt angle adjustment member 5 attached to a base 4 so as to swing the scope 1 within the scope and fix the tilt angle θ at a predetermined value. .

When the monitoring scope 1 (in this case, it is a direct-viewing scope) monitors the combustion status of the burner inside the high-temperature boiler, the monitoring scope 1 (in this case, it is a direct-viewing scope)
is the furnace wall of the boiler;
In the figure, a circular window 7 is formed in the furnace wall of this boiler, and a cover plate 10 is removably fixed to a mounting flange 8 that stands up on the periphery of the circular window 7 with bolts 9 . Therefore, in the illustrated example, this cover plate 10
corresponds to the mounting surface P.

A long hole 11 is formed in this cover plate 10. That is, the elongated hole 11 is formed in the radial direction of the circular cover plate 10, and one end of the elongated hole 11 is located near the outer peripheral edge of the cover plate 10.

The guide and fixing members 3, 3 are arranged on both sides with the elongated hole 11 in between. Its cross-sectional shape is an inverted L-shape as shown in FIGS. 6 and 1, and when attached to the cover plate 10, opposing grooves 12, 12 are formed.

Fitting portions 30, 30 provided at the lower edges of the left and right side wall surfaces of the base 4 are fitted into the grooves 12, 12, as shown in FIG. When the tightening tool 2 is loosened, the pair of fitting parts 30, 30 fit into the grooves 12, 1.
2, and the base 4 becomes movable in the directions of arrows A and B.

Then, by tightening the fastener 2, the base 4
is fixed in that position. 1 and 2 show the case where the base 4 is moved largely in the direction of arrow A, and conversely, FIG. 5 shows the case where the base 4 is moved largely in the direction of arrow B. .

13 is a cover for closing the long hole, which is used when the entire long hole 11 cannot be closed with only the base 4;
This cover 13 is attached. In FIG. 2, this cover 13 is provided on the left side, and in FIG. 5, it is provided on the right side.
It is removably attached to 2 and 12.

As shown in FIG. 4, the base 4 has a two-part structure, and the divided bodies 16, 16 for the hole 14 and the recessed relief part 15, respectively, are joined together by bolt/nut connections 17.

Reference numeral 18 denotes a swing support shaft that forms a main part of the inclination angle adjustment member 5. This swing shaft 18 has a large diameter portion 19 in the center.
It has small diameter parts 20, 20 at both ends, and when the divided bodies 16, 16 are combined as shown in FIG.
0 is inserted into the hole 14. And the large diameter part 19
A scope insertion hole 21 through which the scope 1 is swingably inserted in a direction perpendicular to the axis is provided. Further, 22 is a set screw (adjustment screw) that fixes the rotation angle of the swing support shaft 18 with respect to the base 4, that is, the inclination angle in the orthogonal plane Q of the scope 1, to a predetermined value.

When this adjusting screw 22 is screwed into the screw hole provided through the base 4, the tip of the adjusting screw 22 presses against the small diameter portion 20 inserted into the hole 14,
The swing support shaft 18 is fixed and its rotation around the axis is regulated.

Conversely, if the adjustment screw 22 is loosened from the tightened state, the pressure applied by the adjustment screw 22 on the swing support shaft 18 is released, and rotation around the axis becomes possible.

That is, by loosening the adjustment screw 22,
The swing support shaft 18 can rotate around its axis, and the inclination angle θ in the orthogonal plane Q of the monitoring scope 1 can be adjusted.
can be freely changed, and by tightening the adjusting screw 22, it becomes impossible to change the inclination angle θ.

Further, the tips of the small diameter parts 20, 20 protrude to both sides of the base 4, and a pair of threaded rods 23, 23 are protruded from these protruding parts as shown in FIG. 1, forming a part of the scope 1. Insert the threaded rods 23, 23 into a pair of holes in the mounting plate 25 fixed to a part of the protection tube 24, and screw the nuts 26, 27 (see Fig. 2) back and forth until the mounting plate 25 is aligned with the arrows. By moving it in the C direction, the extent of the protrusion of the protective tube 24 and the tip of the scope into the object to be observed can be increased or decreased.

In the illustrated embodiment, the inclination angle adjustment member 5 includes the swing support shaft 18, the set screws 22, 22,
It is composed of a screw rod 23, nuts 26, 27, etc., but it goes without saying that other than these, the design can be changed freely.

Note that, as shown in Fig. 1, when a circular cover plate 10 is attached using bolts 9 arranged at equal pitches around the circumference, and the guide and fixing member 3 is attached using this cover plate 10 as the mounting surface P, is the reciprocating adjustment shown by arrows A and B, and arrows E and F (see Figures 2 and 5).
In addition to adjusting the inclination angle θ shown in , it is also possible to adjust the position of the entire surveillance scope mounting device by rotating it in the direction of arrow G in FIG. This has the advantage of making it easier to monitor and observe the inside of the boiler, which is complexly arranged. Of course, in the present invention, it is also desirable to directly attach it to the wall surface 6 without using such a cover plate 10, and it goes without saying that the wall surface 6 may be a vertical surface or an inclined surface.

[Effect of idea]

Guide fixing members 3, 3 for direct-view monitoring scope 1
In addition to being able to freely move the monitoring scope 1 in the direction along the orthogonal plane Q, the inclination angle θ of the monitoring scope 1 within the orthogonal plane Q can be freely adjusted, making it possible to easily change the part to be observed. ,
This is a difficult-to-see area to be observed, but it can be seen reliably and easily, and almost the entire interior of various furnaces can be observed.

Also, during observation, the monitoring scope 1 is securely fixed, does not move in the direction along the guide and fixing members 3, 3, or swings within the orthogonal plane Q, and does not move in the direction along the guide and fixing members 3, 3, or swing within the orthogonal plane Q. The observation site can be reliably observed in a stable state.
