Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to an airframe installation and adjustment device for installing an airframe such as a steam turbine casing on a foundation frame with a liner interposed between anchor blocks and legs. It is.

(Prior Art) To explain a conventional example of the installation adjustment of a steam turbine, a transverse anchor block is used to level the turbine casing and install it on a foundation base. The base main body is embedded in the foundation frame, and a leg protruding from the turbine casing is fitted into the upper protrusion, and an L-shaped leg is fitted between the anchor block and the leg of the turbine casing. The structure is such that the positioning and adjustment of the turbine casing is performed by disposing liners of 1 and 2, and the adjustment is performed by adjusting the thickness of the liner. The structure is such that thermal expansion of the turbine casing is allowed due to relative slippage between the anchor block and the legs of the turbine casing, and when the slippage occurs, In order to avoid misalignment of the turbine casing in the lateral direction (direction perpendicular to the axial center of the casing),
It is necessary to provide the end guide surface (contact surface with the liner) of the anchor block parallel to the axis of the turbine casing. It takes a lot of effort to install the end guide surfaces of the blocks parallel to each other, and if it is discovered that the installation accuracy of the anchor block is incorrect after the anchor block is finished, the end guide surfaces should be It has drawbacks such as the troublesome work required to correct it by hand.

In order to improve the above-mentioned drawbacks, we previously proposed an airframe installation adjustment device that attaches the installation accuracy adjustment liner to the end guide surface side of the anchor block.
No. 58-27048 (Utility Model Publication No. 59-133701).

The above-mentioned fuselage installation adjustment device is explained in detail in Fig. 3 (when the legs are protruding from the end of the turbine casing) and Fig. 4 (when the legs are protruding from the side of the turbine casing). ), a transverse anchor block 2 is embedded on a foundation 1, and a transverse anchor block 2 is installed on the end (Fig. 3) or side ( Legs 4, 4 protruding from the anchor block 2 (Fig. 4) are arranged in a fitted manner on the anchor block 2, and the end guide surfaces 2a, 2a at the upper part of the anchor block and the guide surfaces 4 of the legs 4, 4
L-shaped adjustment liners 5, 5 are inserted between the anchor blocks 2a and 4a, and the adjustment liners 5, 5
The structure is such that adjustment liners 5, 5 are embedded in the gaps between the anchor block 2 and the legs 4, 4 to guide the ends of the anchor block 2. The surface 2a is the guide surface 4 of the leg 4
Even if the arrangement is inclined with respect to a, by adjusting the thickness of the adjustment liner 5 as shown, the guide surface 4a of the leg 4 formed parallel to the axis of the turbine casing 3 can be adjusted. On the other hand, the contact guide surfaces 5a of the adjustment liner 5 can be arranged in parallel, increasing installation accuracy and eliminating the above-mentioned drawbacks.

(Problems with the Prior Art) In the conventional airframe installation adjustment device, as shown in FIGS.
When inserting the L-shaped adjustment liners 5, 5 in the direction of the arrow between the end guide surfaces 2a and 4a,
If the gap between a is wide at the entrance and narrow at the back, as on the A side, the adjustment liner 5 can be inserted easily, but when the entrance is narrow and the back is wide, as on the B side, it becomes difficult to insert the adjustment liner 5. In steam turbines, the insertion direction of the adjustment liner 5 is often limited to one direction,
There are problems such as difficulty in inserting and arranging the adjustment liner and lack of reliability in installation and fixing performance.

(Purpose of the invention, means for solving problems) This invention is an invention to deal with the above-mentioned problems.
A configuration in which an adjustment liner having an adjustment guide surface parallel to the landing gear guide surface of the aircraft body is attached, and an embedded liner having a surface parallel to the landing gear guide surface and the adjustment guide surface is attached to the landing gear guide surface of the aircraft body. It has the characteristics of
By installing a liner for adjusting installation accuracy on the end guide surface side of the anchor block, and installing a fill-in liner for the gap on the leg guide surface side opposite to the end guide surface, it is possible to In addition to making it easy to insert the liner between the leg guide surface and the adjusting liner, the adjustment liner eliminates misalignment of the anchor block end guide surface, increasing installation accuracy, and eliminating the gap with the embedded liner. , installation performance,
It is an object of the present invention to provide an airframe installation and adjustment device that significantly improves reliability and eliminates the above-mentioned problems.

(Embodiment of the invention) Fig. 1 and Fig. 2 show an embodiment of the invention and its modification. FIG. 2 shows a modified example in which legs 4 are provided protruding from the side (side surface) of the fuselage 3, and 1 in the figure is a foundation mount;
2 is a transverse anchor block whose base body is embedded in the foundation frame 1, 3 is the fuselage body (for example, a turbine body), and 4, 4 is the end part (Fig. 1) or side part (second part) of the fuselage body 3. In the present invention, an L-shaped adjustment liner 1 is provided on the end guide surfaces 2a, 2a of the anchor block 2.
5 and 15 with bolts 6 and 6, and an L-shaped embedded liner 1 is installed on the guide surfaces 4a, 4a of the legs 4, 4 facing the end guide surfaces 2a, 2a.
6 and 16 are attached and fixed with bolts 6 and 6, and the adjustment liners 15 and 15 are for eliminating the imbalance of the end guide surface 2a of the anchor block 2 with respect to the guide surface 4a of the leg 4. When attached to the end guide surface 2a of the anchor block 2, the leg 4
Adjustment guide surface 15 parallel to the guide surface 4a of
The adjustment liner 15 is attached to the end guide surface 2a of the anchor block 2 to correct the misfit of the end guide surface 2a to the base frame 1, that is, the leg 4. By eliminating the deviation of the parallelism to the guide surface 4a,
The installation accuracy of the embedded liners 16, 16 is improved.
is inserted and embedded in the gap between the adjustment liner 15 and the guide surface 4a of the leg 4 to eliminate the gap.

(Function) The embodiment of the present invention has the above-mentioned configuration, and the legs 4, 4 on the fuselage 3 side are arranged in a fitted manner on the anchor block 2, which is embedded and cast on the base frame 1. When constructing the structure, first insert the adjusting liners 15, 15 into the end guide surfaces 2a, 2a of the anchor block 2, fix them with bolts 6, 6, and attach the embedded liners 16, 16 to the adjusting liner 15. ,1
5 and leg guide surfaces 4a, 4a, and bolt 6,
Attach it to legs 4 and 4 in step 6.

The maximum width of the adjustment liners 15, 15 is determined by the end guide surface 2a of the anchor block 2 and the guide surface 4a of the leg 4.
Since it is possible to form a gap smaller than the minimum width between 15a
can be adjusted according to the installation error of the end guide surface 2a of the anchor block 2 during casting, and becomes parallel to the guide surface 4a of the leg 4, thereby increasing the installation accuracy of the fuselage 3. Furthermore, the embedded liner 16 can be easily inserted into the gap between the adjustment guide surface 15a of the adjustment liner 15 and the guide surface 4a of the leg 4, which are arranged in parallel, and can be fixedly installed. Included liner 16
can be adjusted by adjusting the width of the front gap before insertion and taking into account the parallelism between the guide surface 15a and the guide surface 4a, and the width between the anchor block 2 and the legs 4, 4. the adjustment liner 15,
15 and the embedded liners 16, 16 are eliminated, and the installation performance and reliability of the fuselage 1 are significantly improved. In the above embodiment, the casing of a steam turbine was mainly described, but the present invention can be widely applied to the body of various equipment.
