Moreover, lever insertion grooves facing each other are formed in upper and lower ends of a through hole of the spherical bolt, such that the spherical bolt can be fastened to or separated from the adjustment nut by using the lever insertion grooves, and thus, the height adjustment operation is not interrupted even when an obstacle such as a jack-up bolt is located in an installation space of the ship leveling apparatus, thereby improving workability and precision.

Description

[0001] SHIP LEVELING APPARATUS FOR EQUIPMENT COMPRISING ENGINE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a leveling device for a ship in an equipment including an engine, more specifically, to improve a bearing capacity of a load of a heavy equipment such as a marine engine, The present invention relates to a leveling apparatus for a ship capable of reducing the number of leveling devices and lowering the height of a leveling device for a ship so that the device can be used without limitation within a limited space and consequently the height of the equipment can be lowered to improve the structural stability and space utilization of the ship .

Generally, a solid steel chock and a liquid resin chock are used for equipment height and horizontal alignment when installing various equipments.

Steel chokes are difficult to install and require a lot of time because the steel plate must be installed several times by the operator while machining the steel plate to fit the space between the seat plate and the bed plate of the equipment. The disadvantage that the choke can not be reused when moving or reinstalling the equipment .

The resin chock works by pouring liquid resin into the space between the seat plate and the bed plate of the equipment. Therefore, it is necessary to install a separate dam to prevent the resin from overflowing although the work difficulty is lower than that of steel chock. The size is increased due to the low load strength, and the choke can not be reused at the time of equipment movement or reinstallation.

In order to overcome these disadvantages, a leveling device for adjusting the level and height of the equipment has been proposed. Conventional leveling devices are installed in the space between the bed plate and the seat plate and are fastened with foundation bolts and are configured to adjust the height and level of the equipment placed on the bed plate while the spherical washer rotates within a certain angle range.

However, the conventional leveling apparatus has the following problems.

First, unlike a small-sized equipment such as a prime mover, a motor, or a work piece, the marine engine has a weight of several tens to several hundreds of tons. However, since the fastening area (tightening area) between the nut and the bolt is small, That is, the load bearing capacity is weak. Therefore, in order to support equipment having a large load such as an engine for a ship, a greater number of leveling devices are required at leveling, and the size of the leveling device is increased, there is a problem.

Second, in a conventional horizontal adjustment apparatus adopting a screw-coupled structure, there is a problem that when the apparatus is actually operated, vibration of the apparatus occurs and the screw is loosened or locked so that the height of the apparatus is arbitrarily changed. And the horizontal balance is broken, which may cause damage to the equipment.

Third, the height of the space in which the leveling device is installed may be limited depending on the type of the equipment or the installation location. In such a limited space, there are many restrictions on installing the leveling device with high height, Do.

Fourth, after inserting the lever in the lever insertion groove formed on the outer peripheral surface, the nut is fixed and the bolt is rotated horizontally to adjust the horizontal and height of the equipment. However, Since the obstacle such as a jack-up bolt is positioned, interference occurs in the fastening and separating operation (horizontal height adjusting operation), it is difficult to turn the bolt horizontally by using only the straight lever.

1 is a perspective view of a seat assembly according to an embodiment of the present invention. FIG. 2 is a perspective view of a seat assembly according to an embodiment of the present invention. Is a ship leveling device for tightening the height and horizontal of the equipment (1) by being fastened by a foundation bolt (30) connecting the plate (20). In the present invention, the equipment (1) includes a heavy-duty marine engine, a generator, a speed reducer, various equipment of a steering and engine room, and a deck machinery.

The leveling apparatus for a ship according to the present invention relates to a leveling apparatus for a ship for adjusting the height and level of equipment including an engine for a marine vessel, The seat plate 20 includes a plate to be welded to a bottom surface (for example, a ship deck).

The bed plate 10 is installed at a predetermined height on the seat plate 20 by fastening the foundation bolts 30 and the leveling apparatus of the present invention is passed through the foundation bolts 30, And serves to adjust the height and level of the equipment (1) in the space between the plates (20).

As will be appreciated, marine engines, by their nature, unlike lightweight equipment such as prime movers, motors, or workpieces, have a weight of tens to hundreds of tons or more.

As described above, in the conventional leveling apparatus, since the fastening site between the nut and the bolt is short (the fastening area is small), the overall height of the leveling apparatus is made high so that the supporting force against the load of the equipment, A larger number of horizontal adjustment devices are required to support heavy equipment such as marine engines, and the size of the horizontal adjustment device is increased, resulting in increased manufacturing costs and inferior workability and precision.

In addition, since the height of the leveling device is high, it is difficult to install in a limited space, and the height of the marine engine is also increased, so that the center of gravity of the marine vessel rises and the structural stability of the marine vessel is deteriorated.

In order to solve these problems, the marine leveling apparatus of the present invention has the following technical characteristics.

Since the load of a heavy load such as the ship engine is transmitted to the spherical bolt 120 and the adjustment nut 110, the joint between the spherical bolt 120 and the adjustment nut 110 is formed to be long do. That is, the length of the thread portion is made longer, or the screw connection area is widened.

In other words, in the ship leveling apparatus of the present invention, the height h1 of the male thread 120a of the overall height H of the spherical bolt 120 is formed to be larger than the height h2 of the flange 123, When the leveling device for a ship according to the present invention is used for equipment 1 having a high weight such as a marine engine, the load supporting force is greatly improved, and the leveling of the leveling device 110a and the male screw 120a, And the size of the vessel leveling apparatus itself is reduced, thereby reducing the manufacturing cost and reducing the construction cost.

In addition, the leveling apparatus for a ship according to the present invention can lower the height of the apparatus, thereby improving the structural stability and space utilization of the ship by lowering the height of the apparatus 1, and even when the installation space for installing the ship leveling apparatus is limited There is a technical feature in that it can be used without restrictions.

Hereinafter, the marine leveling apparatus according to the first to third embodiments of the present invention will be described.

1 to 4, a ship leveling apparatus 100 according to a first embodiment of the present invention includes an adjustment nut 110 installed on an upper surface of a seat plate 20, a spherical bolt 120, And a washer 130.

The adjustment nut 110 is formed in an annular shape, and a female screw 110a is formed on an inner circumferential surface thereof, and at least one lever insertion groove 111 is formed on an outer circumferential surface thereof.

The spherical bolt 120 has a through hole 122 through which the foundation bolt 30 is inserted, and a flange 123 is formed on the outer circumferential surface of the spherical bolt 120. The flange 123 may have a lever insertion groove 121 formed therein. The flange 123 is formed so as to protrude further in the outer peripheral direction than the male screw 120a described later.

A lever insertion groove 125 may be formed at the upper and lower ends of the through hole 122 to fasten or separate the spherical bolt 120 to the adjustment nut 110. [

The lever insertion groove 125 may be formed with the lever insertion groove 121, or only the lever insertion groove 125 may be formed. The lever insertion groove 125 is a hole for inserting an end of a T-shaped lever 50 to be described later, and the lever insertion groove 121 is a hole for inserting an end of the linear lever.

The outer diameter d1 of the flange 123 of the spherical bolt 120 is formed to be larger than the outer diameter d2 of the lower outer circumferential surface of the spherical bolt 120 and the outer circumferential surface of the spherical bolt 120 is fastened with the female screw 110a A male thread 120a is formed. The spherical bolt 120 is formed with a concave portion 124 having a certain curvature on its upper surface. The standard adjustment height of the spherical bolt 120 may be 5 mm, and the adjustment height of the spherical bolt 120 may be 5 mm or more according to the design conditions.

A lever insertion groove 121 may be formed in the flange 123 of the spherical bolt 120 to fasten or separate the spherical bolt 120 to the adjustment nut 110. [

The spherical washer 130 is formed with a through hole 132 through which the foundation bolt 30 is inserted along the center of the spherical washer 130. The spherical washer 130 has a predetermined angle range (for example, The concave portion 124 and the convex portion 134 corresponding to the concave portion 124 are formed. The maximum adjustment angle of the spherical washer 130 can be increased by changing the height h3 of the spherical washer 130. [

The thread of the present embodiment can be constituted by a triangular screw or a tooth thread, and coating or plating may be performed on the entire constituent parts in order to prevent corrosion. Rust-preventive oil may be applied to the contact portion (spherical surface) of the spherical washer 130 and the spherical bolt 120, and to the female screw and male screw.

As described above, in the present embodiment, the means for improving the load-bearing capacity of the high-load equipment 1, that is, the means for improving the load-bearing capacity, The height h1 of the male screw 120a is formed to be larger than the height h2 of the flange 123 among the height H so that the fastening portion of the female screw 110a and the male screw 120a The ratio of the height h2 to the height h1 is set to 1: 2 or more, or the tightening ring 140 is fastened to the adjusting nut 110, And a structure for supporting the lower portion of the main body 120. [

The ratio of the height h2 to the height h1 is preferably 1: 3 to 5, and although not shown in the figure, the lever insertion groove 121 is omitted in the flange 123, and only the lever insertion groove 125 The ratio between the height h2 and the height h1 may be 1: 6-7.

The ratio of the height h3 of the spherical washer 130 to the height h2 of the flange 123 may be 1: 1 to 3 and the height h3 and h4 may be 1: 3 to 9.

The outer diameter d3 of the adjustment nut 110 may be formed to be relatively larger than the outer diameter d1 of the flange 123. [

This specific height ratio is not limited to simple numerical limitations as it was invented by the inventors of the present invention over many years of research and development. In this embodiment, the number of leveling devices for ships required for leveling can be greatly reduced due to the improvement in load bearing capacity, the size of the leveling device for ships can be greatly reduced, and the height of the leveling device for ships can be reduced. And as a result, it is possible to increase the structural stability and space utilization of the hull by lowering the height of the equipment.

Also, since the tightening loosening phenomenon in which the spherical bolt 120 is loosened and the flow (shaking) occurs is caused by the vibration generated in the engine, the tightening ring 140 is fastened to the adjusting nut 110 The lower part of the spherical bolt 120 can be supported to prevent the tightening loosening of the spherical bolt 120 and to further increase the load supporting force.

The fastening ring 140 has a through hole 142 through which the foundation bolt 30 is inserted and a male screw 140a for fastening the fastening ring 140 to the female screw 110a is formed on the outer circumferential surface .

A lever insertion groove 145 may be formed at the lower end of the through hole 142 of the fastening ring 140 to fasten or separate the fastening ring 140 to the adjusting nut 110. [

In the conventional leveling apparatus, when leveling is used, there arises a problem that the height of the apparatus is arbitrarily changed due to loosening or locking of the screw-engaging portion when vibration of the apparatus occurs. In the present invention, however, the fastening ring 140 is further fastened to the adjusting nut 110 That is, as the fastening ring 140 is fastened to the adjusting nut 110, the threaded portion, that is, the fastening portion (fastening area) The load bearing capacity is further improved.

6, the leveling apparatus 100 for a ship according to the present invention is configured such that the ratio of the height h2 to the height h1 is 1: 2 or more, The height of the equipment 1 can be reduced and the height of the equipment 1 can be greatly reduced, thereby improving the structural stability and space utilization of the hull.

As a result, as shown in FIGS. 5 and 6B, the leveling apparatus 100 for a ship according to the present invention is provided with a relatively large jointing area (fastening area) as compared with the flange 123, The number of leveling devices for a leveling vessel used for leveling can be greatly reduced and the size of the leveling device for a vessel can be optimized to a small size when supporting a heavy equipment (1) such as a marine engine. In addition, the height of the spherical washer 130 can be lowered to be installed in a limited space, and the height of the equipment 1 can be lowered, thereby improving the structural stability and space utilization of the hull.

The contents are the same as those of the first embodiment, and therefore, reference is made to FIG.

The outer diameter of the adjusting nut 310 is formed to be relatively larger than the outer diameter of the flange. This is the same as that of the first embodiment, and therefore, reference is made to FIG.

The clamping ring 340 is fastened to the adjusting nut 310 to prevent the clamping loosening of the spherical bolt 320 fastened to the adjusting nut 310 and to increase the supporting force of the equipment 1 against the load, And a lever insertion groove 345 is formed at the upper or lower end of the through hole 342 of the spherical bolt 320 to fasten or separate the spherical bolt 320 to the adjustment nut 310 .

As described above, according to the present invention, the total height of the spherical bolts is formed so that the height of the male thread is relatively larger than the height of the flange, so that the fastening portions of the adjustment nut and the spherical bolt are relatively large. That is, since the engagement area of the adjustment nut and the spherical bolt is relatively large, the load supporting force is greatly improved in the leveling operation for heavy equipment such as a marine engine, thereby drastically reducing the number of ship leveling devices used for leveling. That is, the load supporting force of the leveling device is determined by the height of the threaded portion where the adjusting nut and the spherical bolt are combined. In the present invention, the height of the threaded portion can be increased.

In addition, by fastening ring at the bottom of the spherical bolt, it is possible to prevent the loosening or locking of the spherical bolt due to vibration of the equipment, so that the height of the equipment is kept constant and the height of the threaded portion is further enlarged, There are advantages to be able to.

In addition to reducing the size of the ship leveling device (miniaturization), the height of the ship leveling device is lowered, resulting in a reduction in manufacturing cost, improved workability, and greatly reducing the height of the equipment, thereby improving the structural stability and space utilization of the ship .

In addition, a lever insertion groove is formed at the upper and lower ends of the through hole of the spherical bolt, and a spherical bolt is fastened to or separated from the adjustment nut using the lever insertion groove Therefore, even if an obstacle such as a jack-up bolt is located in the installation space of the leveling device for a ship, it is not interfered with the height adjustment work at all, and therefore, workability and accuracy can be improved.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Accordingly, such modifications or variations are intended to fall within the scope of the appended claims. For example, although the present invention is applied to an apparatus including a marine engine, it is also applicable to bridges, buildings, and the like. In addition, the term "large", "long" or "high" in the fastening portion has the same meaning and can be interpreted as a larger fastening area. In addition, loosening or locking (fastening) means that the adjusting nut and the spherical bolt threading are separated or fastened.
