Description

[Detailed Description of the Invention] The present invention relates to a level adjustment device in a shipboard plant.

Recently, a paper manufacturing plant was assembled on a barge at the dock.
It has been proposed that this barge be transported by tugboats to the site where the pulp logs are collected, and that paper be produced from the pulp logs in an integrated manner on site.

If the paper manufacturing plant is assembled in advance on a barge at the dock and transported to the site in this way, there is an advantage that it can be easily installed even when it is difficult to construct a paper manufacturing plant on site.

However, in order to assemble a paper manufacturing plant on a barge,
It is not possible to install a concrete foundation like when building above ground, making it difficult to adjust the level of the paper manufacturing plant.

The present invention was developed in view of the above-mentioned circumstances, and its purpose is to provide a level adjustment device that can easily adjust the level of a shipboard plant assembled on a barge. Both sides of the bottom of the shipboard plant are swingably supported by round rod-shaped support members, and a liner is driven into either side of the bottom of the shipboard plant to adjust the level of the shipboard plant. The point is that it is structured as follows.

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, a plurality of floors 2 are provided on the deck of a barge 1 that is towed by a tugboat (not shown), and a press section 3 of a paper machine, for example, is installed on the second floor 2.

This press section 3 consists of a pair of upper and lower rolls 5 that squeeze the wet paper 4 fed from a rope section of a paper machine (not shown) to squeeze out moisture.
, 6 arranged in the transport direction of the wet paper web 4 is installed on the floor 2 via a level adjustment device 8.

A plurality of level adjusting devices 8 are disposed at the bottom of the frame 7 at predetermined intervals, and adjust the level of the frame 7.

In the figure, reference numeral 9 is felt, one end of which is wound around the lower roll 6 of the pair of upper and lower rolls 5 and 6, and the other end is a guide provided on the frame 10 installed below the floor 2. It is wound around a roller 11 and absorbs moisture from the wet paper 4 passing between a pair of upper and lower rolls 5.6.

The level adjustment device 8 is constructed as shown in FIGS. 2 and 3.

That is, there is one support member 14 in the shape of a round bar between the upper block 12 on which the right bottom part of the frame 7 is placed and the lower block 13 placed on the floor 2 opposite thereto.
is mediated.

This support member 14 has an upper half and a lower half formed by a recessed groove 15 having a semicircular cross section and provided in the longitudinal direction at approximately the center of the surfaces of the upper block 12 and lower block 13 that face each other.

The upper end threaded portion 20b is removably locked in locking notches 23 provided on both sides of the bottom plate 18 by tightening a nut 24.

Therefore, when the lower block 13 and the bottom plate 18 are connected to each other by this tightening port 20, the frame 7
The right bottom part of the frame 7 is supported so as not to swing relative to the floor 2, and when the tightening port 20 is removed and the lower block 13 and the bottom part 18 are not connected, the right bottom part of the frame 7 is supported so as not to swing relative to the floor 2. It is swingably supported on the floor 2 by.

On the other hand, there is an upper block 26 in which a plurality of liners 25 (four in the figure) are stacked and the left bottom part of the frame 7 is placed on the liner 25, and a lower block opposite to this is installed on the floor 2. The other support member 28 in the shape of a round bar is also interposed between the support member 27 and the support member 27 .

This support member 28 is parallel to the support member 14, and like the support member 14, its upper half and lower half are located approximately at the center of the opposing surfaces of the upper block 26 and lower block 27. Concave groove 29 with a semicircular cross section provided in the length direction
, 30.

Further, on both sides of the lower block 27, there are a lower block 27 and a frame 7, similar to the lower block 13.
Three tightening bolts 32 are respectively disposed to removably connect to a bottom plate 31 provided on the left bottom surface of the housing.

Therefore, in this case as well, when the lower block 27 and the bottom plate 31 are tied together by the tightening bolt 32, the left bottom part of the frame 7 is supported so as not to swing relative to the floor 2, and this tightening bolt 32 is removed and the lower block 27 and the bottom plate 31 are not connected, the left bottom part of the frame 7 is swingably supported by the support member 28 with respect to the floor 2.

Note that the upper block 26 has a liner 25 on its upper surface.
A plurality of layers are stacked to have approximately the same thickness as the upper block 12.

In the figure, reference numeral 33 denotes mounting plates disposed on both sides of the lower block 27, on which the lower end mounting portion 32a of the tightening port 32 is pivotally mounted via a pin 34.

35 are locking notches provided on both sides of the bottom plate 31;
The upper end threaded portion 32b of the tightening port 32 is tightened and removably retained by a nut 36.

Next, level adjustment of the frame of the press section will be explained with reference to FIG.

In addition, what is shown in FIG. 4 is a case where the left side of the frame 7 is lower than the right side.

First, tighten the tightening port 20.32 of each level adjustment device 8.
Loosen the nuts 24.36 on the upper end threaded parts 20b, 32b, and tighten the tightening ports 20.32 on the lower end mounting parts 20a, 32a.
Using this as a fulcrum, tilt and remove the upper end threaded portions 20b and 32b from the locking notches 23 and 35 of the bottom plates 18 and 31.

Next, lift the bottom plate 31 slightly using a jack or the like.

Then, the frame 7 uses the support member 14 as a fulcrum, and the left side of the frame 7 is tilted upward, so that the liner 25 can be inserted and removed.

At this time, the keyway 19 of the bottom plate 18 and the upper block 1
Since the key 17 of No. 2 is engaged, the bottom plate 18 moves upward from the upper block 12 as the left side of the frame 7 rises.
There is no risk of it slipping off the top surface.

A liner 2 is installed between the upper book 26 and the bottom plate 31.
5 and adjust so that the left bottom of the frame 7 is at the same height as the right measurement part.

Thereafter, the bottom plate 31 of the frame 7 is gently lowered using a hydraulic jack and placed on the liner 25.

Then, tighten the upper end screw portion 20b of the tightening nuts 20, 32 again.
, 32b are locked in the locking notches 23, 35 of the bottom plates 18, 31 by tightening them with nuts 24, 36.

The level of frame 7 is adjusted as described above.

At this time, the upper block 12゜26 is attached to the support member 14.2.
8 to tilt relative to the lower block 13.27, the upper surface of the upper block 12 and the entire upper surface of the liner 25 on the upper block 26 come into close contact with the bottom of the frame 7, and the frame 7 can be stably supported.

Therefore, the rolls 5 and 6 disposed on this frame 7
When rotating, no unreasonable force is applied to the bearing portion, and the roller rotates in a stable state, and the distance between the rolls 5 and 6 is constant and does not change.

Note that if the left side of the frame 7 is higher than the right side, the liner 35 may be removed instead.

In addition, although the above-mentioned embodiment showed the case where it was applied to the press section of a paper machine, it can be similarly applied to the rope section and drying section of a paper machine.

It goes without saying that the present invention can also be applied to level adjustment of a generator, etc., not only in a paper manufacturing plant but also in a case where a generator is assembled on a barge, for example.

As explained above, according to the level adjustment device of the present invention,
An upper block is swingably provided on at least two lower blocks provided apart from each other via a round bar-shaped support member, and a liner is laminated on one of these upper blocks to form both upper blocks. After adjusting the above to the same height, the level of the above-mentioned shipboard plant was adjusted by placing the shipboard plant on both upper blocks and tilting both upper blocks to make surface contact with the shipboard plant. , the level adjustment work of the shipboard plant can be easily performed, and the shipboard plant is supported in a stable state.

Further, since the upper block and the bottom of the shipboard plant are always parallel to each other by tilting the upper block, the liner to be stacked can be made into a flat plate shape, and the liner can be processed easily and with high precision.

Therefore, the accuracy of level adjustment can be improved.

Further, by appropriately changing the number and thickness of the liner layers, the level can be adjusted over a wide range.

It has excellent effects.
