Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a plastic pallet set,

The present invention relates to a pallet set of a plastic material replacing a wooden pallet which has conventionally been used for the loading of shells. More specifically, the present invention relates to a general pallet capable of mixing military 155 mm shells, To a socket for fixing a warhead.

(A) The 155 mm diameter shell is the standard shell of the West, including NATO. Its history is very old, but it is widely used today. Of course, the ROK military will also be active in the future for a while.

Artillery weapons systems that require large-scale stockpiles and training shots are more compatible and versatile than any weapon systems in handling. Recent trends (to address the lack of destructive power) have been to maintain the current 155mm diameter, which is more compatible with the current equipment, rather than developing a new type of bullet and new type of expanded bulb, Has been responding by the development of customized charcoals by gradually diversifying the seeds.

In other words, although the maximum diameter of the shell remains unchanged, various types of shells are being developed in the structures of the warhead, the body, and the anchor, and their types and handling amounts are increasingly increasing.

If you look at the types of 155mm guns that have been used recently, it has been used since the beginning of the introduction, and it is equipped with the standard type high explosive which is the most stockpile now, the range extension gun with extension of drag range by attaching the drag reduction propulsion part to the anchor, Charcoal-emitting carbon contained in the charcoal emission structure, and induction-type carbon in which an induction function is added to the warhead or anthropomorphic wing after being deployed, Can be mixed and designed.

Naturally, the above special bullets are different in the length of the bullet (height of stacking) compared with the conventional high-grade bomb, and the shape of the bulge and the anchorage part of the fuse and the taper angle and diameter of the bullet and anchor are slightly different.

(B) The material of the pallet currently handling 155mm shells is wood. Wood has the ability to absorb moisture, which is somewhat helpful in preventing moisture in the storage of ammunition, but it has the disadvantage of being deformed, crumbled, and corrupted by moisture during storage.

As a substitute material for wood, plastic materials which are gradually widened in scope of use are excellent in dimensional accuracy and not corrupted, which is a good material to solve most of the disadvantages of wood.

However, there is a disadvantage in that it is difficult to form a thick cross-section when a bulky shape such as a pallet is manufactured. However, in order to compensate this, a plurality of ribs and a compartment structure are closely arranged to reinforce the structure.

Conventional 155mm artillery wood pallets have been in short supply life due to their short reuse life, but they have been disadvantageous in polluting the environment during frequent replacement process because they were chemical treated anticorrosive materials. In addition, due to the low dimensional accuracy, height difference occurred at multi - stage loading, which was more serious when mixed multi - roof pallets of three or more models were used for each model, resulting in load tilting.

Moreover, because of the low workability inherent in wood, which is difficult to make with complicated shapes, the shape of the top plate pallet is merely a hole that has been drilled, so that the hook of the warhead stopper that finishes the fuse mounting part is exposed on the pallet, There were many inconveniences such as.

In addition, the lower pallet is constructed with a pedestal attached to the floor to multi-stage the shell over exposed warhead rings. As a result, the floor support structure is unstable in the form of a tentacle so that it tilts easily, and there is always a risk of collapse in multi-stage loading. (See Fig. 1)

The technical problem of the present invention is to solve all the problems of the conventional artillery pallet described above comprehensively.

In order to solve the problem of exposing the warhead ring on the top plate in the process of covering the pallet top plate on the shell, the present invention is designed to have a crater-shaped perforated hole in the top plate.

The portion directly contacting with the warhead is a bullet insertion hole 41 and has a narrow diameter hole at the lower end of the upper plate. A portion of the bulging portion 42 that surrounds the bullet hole is sufficiently higher than the height of the warhead ring, The height of the warhead insertion ball was set low enough.

Next, the present invention has a multi-stage anchorage receiving portion 61 having at least two stepped structures in the process of placing the anchor portion under the shell on the pallet bottom plate. This is to match the height of the top plate when loading shells of different lengths together in one set of pallets or adjacent sets of pallets.

There is a problem that it is not solved by adjusting the height of the head portion by changing the height of the bottom portion. In the present invention, the problem is solved by a circular ring-shaped socket 50 detachable from the pallet upper plate 40. The present invention solves the problem of the diameter difference at the insertion hole contacting portion due to the difference in the taper angle Respectively.

The inside of the socket is formed with a warhead supporting protrusion 53 which is designed to be compatible with all kinds of 155 mm guns by calculating the height from the anchor seating portion 61 to the supporting point inside the socket.

Due to the organic combination of the above three components, the upper and lower support structure adjusted to the length and shape of the shell is completed, and the bullet hook is not exposed, so that a secure densely stacked structure can be achieved without any problems in multi-stage loading.

In the detailed description that follows, several more detailed designs are added in a direction consistent with the above design improvement directions. All of these become major technological solutions for implementing macroscopic better-performing sockets and ammunition-carrying pallets.

The pallet set according to the present invention not only improves the stability of loading in the ammunition storage process beyond the limit of conventional wooden pallets which are mixedly loaded with various kinds of seeds, So that the strength and the service life are equal to or higher than those of the conventional pallet set, and the manufacturing and maintenance cost is greatly reduced.

In addition, it is possible to transport various kinds of ammunition to a set of compatible pallets quickly and safely in extreme environments such as exhibitions by applying detachable warhead fixing sockets that are difficult to find in conventional pallets.

BRIEF DESCRIPTION OF THE DRAWINGS The above and other objects, features and advantages of the present invention will be more apparent from the following description taken in conjunction with the accompanying drawings, in which: FIG.

However, in the embodiments described below, the components expressed in the specific terminology and the combination structure thereof do not limit the technical idea that is included in the present invention in a comprehensive manner.

The present invention largely consists of three parts: an upper plate 40, a socket 50 and a lower plate 60. Among the reference numerals, reference numeral 40 is an individual structure constituting the top plate, and the other codes follow the same rules.

FIGS. 2 to 3 are views for explaining the shapes and structures of the upper pallet of the present invention. FIGS. 4 to 5 are views for explaining the shapes and structures of the lower pallet of the present invention. FIGS. And the like.

All of which are made of a plastic material and have a reinforcing structure by arranging ribs. The inner structure is reinforced by the compartment structure 47 of the upper plate and the reinforcing ribs 66, which can be called a micro compartment structure. The socket is provided with a warhead support projection (53) densely arranged toward the center on the inner circumferential surface, but it also plays a role of reinforcement of the structural strength in addition to its original function as described below.

Look at the top plate 40. 2 * 5 = Ten shells can be loaded, and a warhead insertion hole 41 into which the warhead of the shell is inserted is formed. (The number of shells can be slightly different depending on the needs and the characteristics of the plastic material.)

Around the warhead insertion hole 41, there is formed a depression 42 similar to a volcanic crater shape so that a cap-shaped warhead ring blocking the bullet of the shell, specifically, the bulb mounting portion, does not protrude above the upper surface of the upper plate.

A lower plate support protrusion 46 for supporting the lower plate 60 at the time of multi-stage stacking is further formed around the depressed portion 42. These not only prevent abrasion but also prevent the load from concentrating at a specific point of the thin plastic plate (See Fig. 10).

Look at the bottom plate 60. Ten anchorage receiving portions 61 having a structure capable of loading 2 * 5 = 10 shells just like a top plate and having an ankle rest of a shell are formed at positions corresponding to the warhead insertion holes 41 described above.

A drain hole 62 is formed in the center of the anchorage receiving portion 61 so that water condensed on the surface of the shell can be drained downward.

Further, a rope guide groove 63 for guiding the sling rope for lifting work is further formed on the left and right side edges of the fork insertion hole 64 on the front surface of the lower plate 60 to facilitate the lifting work by the rope.

Look at the socket 50. The socket is used by being fitted in a pallet upper plate (40) provided with a warhead insertion hole (41) and serves to support the warhead of the shell. The insertion ring 51 formed in the upper portion of the socket is a portion to be fitted in the warhead insertion hole 41 and a support ring 52 having a larger outer diameter is formed under the insertion ring 51 to firmly support the load of the upper plate .

Supporting projections 53 are formed on the inner circumferential surface of the support ring 52 in such a manner as to be able to be fitted and supported in accordance with the shape of the warhead of the loading shell. These are formed by mixing a vertical cylindrical shape and a tapered cylindrical shape, It has a design structure that can be applied to both the tofu diameter.

A plurality of upper plate fixing hooks 54 are formed on the upper end of the insertion ring 51 to prevent the warhead supporting protrusions 53 from being twisted or rotated. These socket hooking grooves 43 formed on the inner circumferential surface of the warhead insertion hole 41, And then hooked on the hook fixing groove 44 formed at the bottom of the depressed portion 42 so as to be securely engaged and fixed so as to prevent rotation. Of course, if necessary, the upper plate fixing hooks 54 may be slightly loosened to separate the socket 50 from the upper plate 40. [ The socket 50 once hooked to the upper plate 40 is prevented from being rotated by the hook fixing groove 44 and the lower swing is prevented by the support ring 52 and the upper plate fixing hook 54, It can be fixed.

9 to 10, the overall coupling structure and usage pattern of the pallet set of the present invention will be described. 9), and the anchorage receiving portion 61 is inserted into the warhead insertion hole 41 (see FIG. 9), and the warhead insertion hole 41 ) Or a seat height corresponding to the warhead support height of the socket (50). (Figs. 8 and 9)

10 shows a structure in which the lower plate coupling protrusions 45 formed in the upper plate 40 and the upper plate coupling holes 65 formed in the lower plate 60 are very easily aligned and fixed to each other when stacked in multiple stages. The load transmitted through the lower plate inner ribs is effectively dispersed throughout the upper plate through the lower plate supporting projection 46. [

Figure 11 illustrates one set of use and three sets of use of the invention. The strap guide grooves (48, 67) provided at the upper and lower plate edges share the position where the strap is wound, and when the pallet sets are stacked along the front and back surfaces, they can be tied together in one bundle and easily lifted with the same sling. All of the useful effects exhibited on the handling of the shell are made by an organic combination of each sub-structure that has been carefully set in advance.

The present invention has been described above by way of examples of the drawings. In addition, the technical idea included in the present invention is not limited to the above embodiments. In other words, those skilled in the art will recognize that the present invention may be embodied in many other specific forms without departing from its spirit or essential characteristics. But is naturally included in the technical scope of the present invention expressed in the claims.

Although the present invention has been described with respect to 155 mm artillery shells having the largest number of artillery pieces, it is not limited to the shells having a specific diameter, but may be appropriately modified to design an anchorage section and a warhead fixed socket to be variously mountable such as 105 mm, 120 mm, It can be applied to seeds.
