Description

Prefabricated Pallets for Loading Goods {Pallet for loading goods}

The present invention relates to a prefabricated pallet for loading goods mainly used to load and transport chipped rubber material or synthetic water support material.

As the prior art related to the assembled pallet for the goods loading, there are a number of patent applications, such as Patent Application No. 2000-6760, No. 2000-29280, No. 2001-42720 and PCT / KR01 / 01475.

The prior art is coupled to the bottom plate having a coupling groove around the upper edge portion, and coupled through the left and right coupling grooves of the bottom plate and configured to open the locking projections that are engaged with the locking grooves on both sides of the coupling groove when engaged. It is composed of a left and right frame, the front and rear frame coupled to the front and rear coupling groove of the bottom plate to enter between the gap, and the locking mechanism for connecting the four sides frame coupled to the bottom plate and the lamination means to enable lamination.

Looking at the coupling means of the bottom plate and the left and right frame among these major technical components when combining the lower end of the left and right frame to the left and right coupling grooves of the bottom plate recessed inwardly, the inner side of the coupling portion is separated from the inner wall of the recess groove when the front and rear frames are assembled. It is made to be supported by contact with the outer surface is fixed upright in contact with the outer wall of the concave groove during the rim.

Therefore, the inlet of the left and right coupling grooves of the bottom plate must secure a clearance to be opened at a predetermined angle for the engagement of the front and rear frames after the left and right frames are joined. Part of the load, such as raw materials or synthetic water support fee, is introduced into the wide gap with the wrapping vinyl surrounding the load, and the packed vinyl and the load introduced into the gap act as a major obstacle when opening the left and right frames for the lowering work. It is hard and difficult to separate the four-sided frame from the base plate, and in the process of separating the four-sided frame by forcibly opening the left and right frames, the loads caught between the openings are damaged, resulting in a loss of foreign materials between the torn pieces of packaging vinyl. Will penetrate into the material, so it will It will cause change and cause defective products.

In addition, the locking mechanism for connecting the four-sided frame is repeatedly improved, and the lock pin is elastically installed on the pin bracket operated by the handle with a spring. When the locking pins of the left and right frames face the locking holes of the front and rear frames when the four-side frame is assembled, It is designed to be locked by protruding with repulsive force, so that the appearance is beautiful and there is no danger of the lock being canceled due to malfunction by operation handle after locking. When the lock is made in the incompletely coupled state of the front and rear frame, the lock hole of the front and rear frame is displaced from the lock pin of the lock, and only the pin bracket is advanced during the lock operation through the operation handle. However, after the locking operation, If the loading is carried out in the non-locked state of the four-sided frame because it is impossible to check, the four-sided frame is opened due to the pressure of the load, causing the loss of the loaded load and even if it is not found even during the loading process. If the four-sided frame is lost due to the loss of bearing capacity, aside from the loss of the load, it causes a safety accident due to the collapse of the pallet.

In addition, as a stacking means for increasing space utilization during transportation and storage of pallets loaded with loads, a stacking piece having joining protrusions can be installed on the upper edge of the frame so as to be protruding, and a stacking piece having joining holes is provided at the bottom edge of the bottom plate. It is made to form by welding, but this is complicated by the structure to install the upper stacking piece to go out, the manufacturing cost is increased and the use is cumbersome.

Thereafter, as another lamination means, a welding device having a predetermined length consisting of square tubes is welded to the bottom surface of the bottom plate so that the latching part of the upper pallet is engaged with the inner edge part of the frame of the lower pallet when laminating. When the upper pallet is combined correctly from the upper part of the lower pallet, the joining is performed. Therefore, the stacking work is very demanding and the four catches come into contact with the ground so that the catches are easily bent or deformed during handling. Since the lamination cannot be made, frequent repairs are required and many problems are pointed out, such as lack of stability when transporting the conveyor belt.

Therefore, the present invention is to open the left and right frames from the bottom plate for the coupling of the front and rear frame to solve the conventional problems as described above, so that the coupling groove is not exposed in the loading chamber after assembly so that the loss of the load and foreign matter penetration It is possible to prevent the change of physical properties due to the disassembly of the four-sided frame for quick and easy disassembly.The front and rear frames can be combined with the left and right frames only when the bottom plate is completely combined with the lock. The loss of the load due to this can eliminate the safety accidents due to the collapse of the pallet, and the lamination means can be simplified and the lamination can be easily performed without fear of malfunction due to bending or deformation, and the conveyance using the conveyor belt is made stable. Water tank To provide a pallet it is an object of expression.

In order to achieve the above object, the present invention protrudes a joint having a thickness thinner than the width of the coupling groove inlet of the bottom plate from the step of the inner bottom of the left and right frames so that the step is blocked when the left and right frames are assembled. When assembling the frame, the bottom projections of the two halves of the left and right coupling grooves of the left and right frames and the two halves of the two halves of the coupling grooves on the left and right sides of the front and rear frame are combined to form a complete locking projection. Only when the front and rear frame is completely combined, the four-sided frame can be combined, and the bottom edge of the bottom plate is formed with a recess groove so that the stacking protrusion of the lower pallet is coupled to the recess of the upper pallet when stacked to form a stable stack. It is characterized by.
