Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for lateral movement of a hull between parallel inclined slats.

[0002]

2. Description of the Related Art As a hull lateral moving device between parallel inclined slats, it has been conventionally known to use a launching table for longitudinal launch by laying it in the lateral direction of each parallel inclined slat as it is. That is, for example, as shown in the perspective view of FIG. 4 (A) and the cross-sectional view of FIG. 4 (B), the above device is made of Yonematsu fixed on the concrete slab 01 with the anchor bolt 03 through the thin wood 02. A fixed base 04, a lubricant 05 composed of animal fat and soft soap evenly spread on the fixed base 04, a sliding base 07 made of Yonematsu mounted on the fixed base 04 and provided with a rib band 06 on the front side, and It is formed by a pair of upper and lower crushing boards 08 placed on the above, and a holding table 010 placed on this and supporting the bottom 09 of the hull. Here, 011 is a one-point pulling type traction device, 01
2 is a launching stand, 013 is a weight of 1990t, length ×
It is a total assembly block (hereinafter referred to as a hull) having a width of 51.9 m x 24.0 m x 9.40 m. As a document relating to the above-mentioned device, the Shipbuilding Association Paper No. 103 can be cited.

However, such a hull lateral movement device has the following drawbacks. (1) The Yonematsu fixed base 04 is compressed by the weight of the hull and sinks, and since the sinking is uneven due to the uneven distribution of the hull weight distribution, the friction coefficient of the lubricant 05 becomes non-uniform, and therefore the center of the traction reaction force of the hull. Is greatly deviated from the estimated calculation value. (2) Since the sliding table 07 slides along the fixed table 04 with the wooden rib band 06, when pulling the hull 013, a part of the rib band 06 is caused by the deviation of the center of the pulling reaction force and the inclination component force of the hull weight. When the ship is destroyed, the center of the right side of the hull 013 and the center of the left side are one and the other from the planned line for lateral movement of the hull
For example, each shifts by 250 mm. (3) Since the holding table 010 is made by stacking thin wooden boards, the compressibility is large, and therefore, it sinks for 120 mm, for example. (4) Since the horizontal movement of the hull is performed by the one-point towing type towing device 011, it is difficult to control the deviation generated during the lateral movement by the winch of the towing device 011. Therefore, the position correction of the hull 013 installed with deviation is corrected. Work is a big job. (5) After completing the horizontally moved hull 013, in order to launch it, the fixed base 04, etc. are removed, and the fixed base for launching, the slide for launching, the holding platform for launching, etc. Since it is pulled under 09, handling of heavy objects in a low space is performed, and thus there is a problem in work safety.

[0004]

A plurality of sliding steel ball structure bases attached on the horizontal carriage for horizontal movement formed by the fixed base and the bridging member, and an endless wire for horizontal movement of the hull arranged on the floor surface of the concrete foundation. When equipped with a two-point pulling device Characterized by removing the above-mentioned bridging portion material.

[0006]

According to this structure, a plurality of lateral slides for transverse movement are arranged orthogonally to each other on the plurality of vertical slides for launching, which are arranged on the floor surface of the foundation concrete and are parallel to each other. In the horizontal hull lateral movement device between the parallel inclined sills, a plurality of slightly fixed lateral fixed pedestals that intersect at right angles with the fixed pedestal of the launch vertical sill and both sides of the vertical sill. A detachable bridging member having the same height as the lateral fixing base inserted between the opposite ends of the lateral fixing base so as to straddle the fixing base of the launching vertical deck, the lateral fixing base, and the horizontal fixing base. A plurality of steel ball structure bases for sliding attached on a horizontal slide for horizontal movement formed by a bridging member, and an endless wire type two-point pulling for horizontal movement of a ship arranged on the above-mentioned foundation concrete floor surface It is equipped with a towing device, and the bridge members are Since removed by the action of the following is performed. (1) As a result of inserting multiple sliding steel ball structures between the fixed base and the sliding base of the horizontal slide, the sliding friction coefficient on the horizontal slide is maintained evenly and the slippage during hull lateral movement is reduced. . (2) As a result of using the endless wire type two-point towing device for lateral movement of the hull, the deviation during the lateral movement of the hull can be corrected sequentially, and the work to correct the final position of the hull becomes almost unnecessary. (3) As a result of using the temporary lateral movement fixed base that straddles the launch fixed base, the launch fixed base should be placed in advance and only the temporary fixed base should be removed when the ship is launched. There is no need to carry in the launch platform under the bottom of the ship.
