Description

A method for evacuating ships using a jib crane and a ship shelter and a roller support for its implementation are described.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ship evacuation method using a jib crane and a ship shelter and a roller guide bar for carrying out the method. More particularly, the present invention relates to a ship evacuation method using a jib crane, The present invention relates to a ship evacuation method and a vessel shelter and a roller support system for performing the ship evacuation method which can be completed quickly without any moving equipment such as a truck.

Conventional fishing villages where fishery activities are mainly based on relatively small fishing boats are equipped with ship shelters and related facilities in preparation for bad weather such as typhoons.

A typical small ship evacuation method will be described in more detail. The fishing boat to be evacuated is roped up and lifted by a jib crane, lifted over a bogie on the ground, and then transported to a safe zone Replace it.

It is a matter of course that a ship lifting workshop is provided near the fishing village breakwater where fishery activities using small fishing boats are the main business, and a jib crane is installed in each work site.

The ship lifting workshop consists of a concrete floor with a suitable area and a jib crane fixed thereon, especially at a position close to the sea side.

According to the conventional ship evacuation method as described above, it is possible to provide a safe place for transferring a plurality of vessels, that is, a ship shelter, a separate moving equipment such as a truck for moving a ship placed on a car to a ship shelter, It requires personnel and time to move each ship to the shelter.

In other words, according to the conventional ship evacuation method, there is an inevitable problem of a considerable scale of human, material, and time consumption related to the operation of a plurality of separate mobile equipment, while requiring a wide range of places from a ship lifting workshop to a shelter .

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to provide a ship evacuation method capable of quickly completing work without moving equipment such as a truck within a minimum range in lifting and evacuating ships to the ground using a jib crane And a ship shelter and a roller support for its implementation.

The above-described object of the present invention is achieved by developing a ship evacuation method in which a ship is lifted onto a ground vehicle with a jib crane and then dragged and aligned on the floor surface of the workplace around the jib crane.

In other words, according to the ship evacuation method of the present invention, the ship evacuation operation is completed by aligning the loaded car on the floor around the lift work site using the jib crane itself without any moving equipment such as a truck.

As described above, in the case of the present invention, the vicinity of the lifting work site is the ship shelter.

On the other hand, at least in the ship shelter, it is necessary to be able to drag the ship to a point far from the rotation radius range of the jib crane, and a roller support as an auxiliary equipment is required. On the bottom of the ship shelter, have.

The roller supports are rollers, specifically rope guiding grooves formed at the upper end of the support rods in the form of round rods or square rods. Depending on the position to which the vessel is intended to be moved, one or more roller support rods It is fixed.

As described above, according to the present invention, the jib crane can be used to lift and evacuate ships to the ground, and can be quickly completed without moving equipment such as a truck within a minimum range.

In contrast to conventional ship evacuation methods, which require a wide range of locations, from shipbuilding workshops to shelters, to the considerable scale of human, material and time consuming associated with the operation of many separate mobile equipment, It is obvious that a great economic effect will be obtained.

1 is a side view showing a jib crane of a general structure,
2 is a plan view of a ship shelter according to an embodiment of the present invention,
3 is a front view of a roller support according to an embodiment of the present invention;
4 is a plan view showing a ship evacuation process according to the ship evacuation method of the embodiment of the present invention.

As shown in FIG. 1, a jib crane having a general structure, which is mainly used for lifting and evacuating a ship against bad weather, includes a main body 100 fixed vertically on a floor G of a lifting work area, A balancing weight part 300 coupled to one end of the jib part 200 and a balancing weight part 300 coupled to a lower end of the jib part 200 in a horizontal and vertical direction And a hoist portion 400 coupled to the hoist portion 400 in a possible state.

The jib crane constructed as described above is usually remotely adjusted so that the jib 200 rotates (see arrow a) while the hoist part 400 moves horizontally (see arrow b) and vertical (See arrow c).

It is a matter of course that the conveying object suspended from the work ring W at the lower end of the hoist part 400 is moved to the target point in accordance with the movement in the directions of the arrows a, b and c.

As described above, in the ship evacuation method according to the present invention, a ship on which a ship to be evacuated is to be completed can be accomplished by aligning the loaded car on the floor around the lift work site using the jib crane itself without any moving equipment such as a truck A method of evacuating a ship using a jib crane according to an embodiment of the present invention includes the steps of lifting a ship with a jib crane and placing the ship on a ground vehicle, installing one or more roller supports on the bottom of the ship shelter Connecting the rope to the ground bogie and then winding the rollers at the upper end of the rollers support and connecting them to the operation ring of the jib crane; and operating the jig crane's work ring to move the ground bogie and the ship above it to the target evacuation point And a transferring step.

Needless to say, the rope must be wrapped around the vessel before lifting the ship with the jib crane.

It is possible to move the ground bogies and vessels to the target point, then separate the vessels from the bogies and lay them down to the ground separately. However, considering that the bad weather is over and the vessel should be put back on the sea, It is safe to start evacuation next time.

In order to carry out the above method of the present invention, a vessel shelter having a characteristic structure as shown in Fig. 2 is required.

As shown in the figure, the ship shelter 10 according to the embodiment of the present invention includes a jib crane 11 installed to lift a ship and a flat surface 12 formed around the jib crane 11, And a plurality of support table fixing members 13 are provided on the flat surface 12.

In the embodiment, the support table fixing member 13 is in the form of a hole of a corresponding diameter capable of receiving the lower end of the roller support 20 (see FIG. 3) described later.

It goes without saying that the support base fixing member 13 has a different shape and structure according to the shape of the lower end of the roller support 20.

3 showing a roller support serving as an auxiliary mechanism in carrying out the ship evacuation method of the present invention, the roller support 20 of the embodiment includes a support base 21 provided at the lower end of the coupling portion with the support base fixing member 13 And a roller 22 rotatably coupled to the upper end of the support table 21 and having a rope guide groove H formed on the circumferential surface thereof.

Reference numeral "F" denotes a bolt as a fastening means for coupling the roller 22 to the upper end of the support table 21. [

It is preferable that the support base 21 is formed in the form of a rod or a pipe while the support base fixing member 13 is formed into a hole having a diameter corresponding thereto. However, Do.

As shown in FIG. 4, the rope support rope 20 fixed on the bottom surface 12 of the ship has a rope guide groove H which is wound around the upper end rope guide groove H, (Refer to arrow A), the ground vehicle T and the ship S on the ground vehicle T are connected to the target evacuation route T by winding the reels R and connecting both ends thereof to the moving truck T and the jib crane 11, (See arrow B).
