Description

{Portable davit for marine emergency escape}

The present invention relates to a simple type davit, and more particularly, to a simple type davit for emergency escape of a ship that can replace a lifting lug installation work requiring a fire work on a dried vessel.

Referring to FIG. 1, the escape passage 10 on a ship is generally composed of two primary routes and a secondary route. For the secondary route, use a vertical trunk (15) with all sides closed. When a person is injured and the escape path 10 is closed, it is necessary to escape to the trunk 15, but it is difficult to install a crane or a hoist so that it is difficult to escape the injured person.

At this time, there is no rule, but lifting lug should be lifted by hoist or the like by placing lifting lug on each vertical stringer. However, in order to complete the shipbuilding process, there are many tasks such as installation of chieftain, lifting eye welding, repairing of painting and so on. In addition, even if temporary lugs need to be installed in various spaces similar to this, a lot of work is required, so there is a desperate need for a simple lifting method to replace the lugs.

Korean Patent Publication No. 1999-014552 (Prior Art 1) and Korean Patent Registration No. 1176855 (Prior Art 2) are known as prior art documents which can be referred to in this connection.

In the prior art document 1, stairs made of steel structures or ladders capable of moving and transporting are improved, and a lift is installed thereon, so that various articles and the like can be transported and transported. Thus, manpower and time can be greatly reduced and various materials can be easily It is expected to be used for emergency stairs and fire fighting of buildings as well as for transportation.

Prior Art 2 includes an elevator provided with a passage for moving to a driver's seat of a tower crane and having a ladder for entering and exiting through a passage; A winch installed on an upper portion of the mast for lifting and lowering the elevator by winding or unwinding the wire; An elevator yard center guiding vertical movement of the elevator; . Accordingly, it is easy to secure a moving path from the elevator to the tower crane driver's seat, and it is expected that the escape route of the occupants can be secured in the event of various safety accidents.

However, when the elevators shown in the above-mentioned prior art documents 1 and 2 are installed on the escape passage or trunk of the ship, it is not practical to apply the present invention to a ship which is excessively costly due to excessive facilities and dried.

It is an object of the present invention to overcome the above-mentioned problems of the prior art, and it is an object of the present invention to provide an escape route using a trunk while replacing a lifting lug installation work, And to provide a simple type davit for emergency escape of a ship.

In order to achieve the above object, the present invention provides a simple type davit constituting an escape passage using a ladder installed in a trunk, comprising: support means having a hook which is detachably engaged with the ladder; And lifting means having a lifting lug on a column coupled to the support means.

According to the detailed configuration of the present invention, the hooks of the supporting means are provided on the upper and lower legs, which are vertically spaced apart from each other.

At this time, at least one of the upper and lower units of the supporting means is fixed to be adjustable in spacing through a fastener.

According to the detailed construction of the present invention, the hook of the support means is provided with a locking hole for tightly grasping or releasing the foot plate of the ladder.

According to a modification of the present invention, the lifting means is characterized in that the lifting lug is supported so as to be capable of height variation.

As described above, according to the present invention, it is possible to promptly evacuate personnel and materials by securing an escape route in preparation for an emergency by quickly and easily installing the ladder installed in the trunk of the ship.

Fig. 2 is a configuration diagram separately showing a simple type davit according to the present invention; Fig.
Fig. 3 is a schematic view showing a simple type davit according to the present invention in a main section;

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention proposes a simple type davit constituting the escape passage 10 by using the ladder 20 provided on the trunk 15. [ The trunk 15 of the ship is a large pipe structure and serves as a secondary route when escaping. As shown in FIG. 1, a ladder 20 is provided on the trunk 15 in a straight line or zigzag. Although the ladder 20 is connected to the escape passage 10, since it is difficult to use in the case of casualties, it is necessary to lift the ladder 20 upward by using a stretcher, a davit, or the like.

According to the present invention, the supporting means (30) has a hook (35) which is detachably engaged with the ladder (20). The davit of the present invention assumes that the lifting hoist is accommodated and is quickly and easily installed on the ladder 20 using the supporting means 30. [ The ladder 20 includes a footrest 25 to be stepped on, and the footstep 25 is formed of a rectangular rod or an annular rod. The hook 35 of the support means 30 is formed in an inverted U-shape and is detachably engaged with the footrest 25 of the ladder 20.

2, reference numeral 28 denotes a bracket for fixing the ladder 20 to the wall of the trunk 15.

According to the detailed configuration of the present invention, the hook 35 of the support means 30 is installed on the upper and lower legs 31 and 32, respectively, which are vertically spaced apart. The upper and lower legs 31 and 32 have hooks 35 at both ends thereof and are coupled to the column 41 of the lifting means 40 to be described later. The upper and lower spacings of the upper and lower legs 31 and 32 coincide with the distance between the ladder 20 and the foot plate 25. The lateral spacing of the hooks 35 disposed at both ends is determined in consideration of the width of the ladder 20. In other words, if the spacing between the hooks 35 is too large, the engagement is unstable or impossible, and if the spacing is too small, the hooks 35 flow from side to side in the engaged state, which is inconvenient.

At this time, at least one of the upper stage 31 and the lower stage 32 of the supporting means 30 is fixed to be adjustable in spacing through a fastener 38. 3 illustrates a structure in which the lower pedestal 32 is fixed to the column 41 and the upper pedestal 31 is moved up and down in the column 41. As shown in Fig. The upper bag 31 and the column 41 are slidably engaged with each other via a separate member, and the fastener 38 is helically engaged to fix the position variably.

Of course, other known schemes can be applied in fixing the top section 31 on the column 41. For example, a tooth or a plurality of through holes may be formed on the column 41 to increase the meshing pressure.

This makes it easy to adjust the distance between the upper unit 31 and the lower unit 32 by elevating and lowering the upper unit 31 according to the standard of the ladder 20 provided on the trunk 15 and fastening it with the fastener 38.

According to the detailed configuration of the present invention, the hook 35 of the support means 30 is provided with a locking hole 36 for tightly holding or releasing the footrest 25 of the ladder 20. As shown in FIG. 3, the U-shaped hook 35 is engaged with the foot plate 25 and then the locking hole 36 on the bottom is rotated to close the opening to increase the gripping force. Accordingly, it is possible to prevent an accident that the support means (30) is arbitrarily separated from the ladder (20) even when the ship is severely rocked due to the wind storm.

According to the present invention, the lifting means 40 includes a lifting lug 45 on a column 41 coupled to the upper and lower units 31 and 32. The column 41 of the lifting means 40 is coupled with the upper and lower legs 31 and 32 at the lower end and has lifting lugs 45 at the ends as it is bent in the " It is preferable to provide a reinforcing bar 43 at a portion bent at the column 41. The lifting lug 45 is formed to be able to hang a hoist (not shown).

In case of emergency, when a ship emerges and a normal escape is difficult, the simple type davit of the present invention is hooked on the ladder 20 of the trunk 15, moved downward, and then moved to another ladder 20 in the same manner Another davit is used to secure the path, and the davit lifting lug (45) is equipped with a hoist to lift the casualty injured.

As a modification of the present invention, the lifting means (40) is characterized in that the lifting lug (45) is supported so as to be capable of height variation. To this end, a known height adjustment arrangement can be added to the column 41. [ The height of the lifting lug 45 can be quickly changed without separating the hanger 35 when spacing occurs in the process of installing the multi-layered davit of the present invention.

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 and scope of the invention as defined by the appended claims. Accordingly, such variations or modifications should fall within the scope of the utility model registration claims of the present invention.
