Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a transport pallet used to load and transport a load on a transport container such as a container.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, in the transport of heavy loads of 1 to 2 tons such as machines using containers, heavy loads are loaded on iron pallets and loaded into containers, and after the containers are transported to a destination, the entire pallets are transported. Loading and unloading of luggage from containers has been performed.
[0003]
Referring to FIG. 3, when the load G is placed on the pallet 1 by a forklift 10 or an appropriate means, the fork 10a is inserted into the lower surface of the pallet 1 on which the load G is placed in the longitudinal direction, lifted up, and placed on the chassis 12 of the trailer 11. The container 13 is carried into the frontage of the fixed container 13 and lowered onto the floor 14 of the container 13. Next, the header 3 on the front side in the length direction of the pallet 1 is pushed by the fork 10 a, and the pallet 1 is dragged on the floor surface 14 of the container 13 and pushed deep into the container 13.
[0004]
When one or a plurality of pallets 1 on which the load G is placed are loaded in this way and the container 13 is full, the trailer 11 transports the container 13 to the destination. At the destination, a traction rope is attached to the header 3 on the front side in the longitudinal direction of the pallet 1 and pulled by a similar forklift or the like. Then, the pallet 1 is lifted by a forklift, carried out of the container 13 and unloaded.
[0005]
The pallet 1 is provided with a sliding member 9 made of an iron square pipe at a plurality of locations along the longitudinal direction on the lower surface of the longitudinal sliding members at both ends and the intermediate sliding member. This makes the pallet 1 slippery on the floor 14 of the container 13. The floor surface 14 of the container 13 is also made of hard floor material such as chestnut to make it slippery.
[0006]
However, the abrading material 9 has an open end and an edge around the opening, and the apex of the abrading material 9 is cut at a right angle to the length direction, and the opening edge of the apex is at a right angle. Therefore, when a heavy load G of 1 to 2 tons is placed on the pallet 1 and the pallet 1 is dragged on the floor surface 14 of the container 13, the sliding material at the leading end position in the moving direction of the sliding material at both ends of the pallet 1, There is a problem that the lower edge of the opening at the tip of the rubbing material cuts into the floor surface 14 of the container 13 on which the floor material is stretched and is caught, and the pallet 1 on which the load G is placed cannot be smoothly taken in and out of the pallet 13.
[0007]
[Problems to be solved by the invention]
Therefore, as shown in FIG. 4, with respect to the sliding material 9 at the front and rear portions in the longitudinal direction of the sliding material 2 at both ends of the pallet 1, the tip of the sliding material 9 at the outer side in the longitudinal direction faces the lower surface at an angle of, for example, about 30 degrees. By cutting diagonally inward, the lower edge 9b of the opening 9a at the tip of the rubbing material 9 is made obtuse (about 150 degrees). By doing so, it is possible to reduce the possibility that the sanding material 9 bites into the floor surface 14 of the container 13 at the lower edge 9b of the front end opening.
[0008]
However, the tip of the scraping material 9 is still open and the edge 9b remains below the opening 9a, so that the scraping material 9 is inevitably cut into the floor surface 14 of the container 13. In order to prevent this, the iron plate must be welded to the inside of the opening 9a at the tip to close the opening 9a, which requires a troublesome and time-consuming operation.
[0009]
Therefore, an object of the present invention is to prevent a scrap material from being stuck on a mounting surface even when a pallet loaded with heavy loads is dragged on a mounting surface such as a floor of a container, and to smoothly move the pallet. An object of the present invention is to provide a transport pallet in which anti-jamming means can be easily formed.
[0010]
[Means for Solving the Problems]
In order to solve the above problems, the present invention is directed to a metal pallet used for transporting loads, comprising a plurality of metal square pipes along the length direction on each lower surface of both ends sliding material and intermediate sliding material. In the transport pallet with the abrasion material attached, at the longitudinally outer end of the abrasion material located at least in the longitudinal direction of the both ends of the sliding material, a cross section perpendicular to the length direction by corrugating with a press bush. Is characterized by having a corrugated plate-like shape and a lower side having a tip curved upward.
[0011]
According to the present invention, at least one of the sliding members at both ends of the pallet for transportation has a lower side having a curved upper end at a longitudinally outer distal end portion of the rubbing material at the front and rear portions in the longitudinal direction. Even if the loaded pallet is dragged on the placement surface such as the floor of the container, the rubbing material does not get caught, and the pallet loaded with heavy loads can be moved smoothly. Further, since the lower side of the tip of the abrading material is formed by corrugating with a press, the lower side can be formed easily and in a short time by one pressing operation. Further, since the lower side is formed so that the cross section perpendicular to the length direction of the rubbing material is corrugated, the lower side does not protrude laterally in the cross section direction, and the lower side moves the pallet on which the load is placed. There is no hindrance to work.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
[0013]
FIG. 1 is a perspective view showing one embodiment of a transport pallet of the present invention. The transport pallet 1 of the present invention has a basic configuration similar to that of a conventional pallet, and is arranged in parallel at intervals in the horizontal direction. The two-sided sliding members 2 and 2, the headers 3 and 3 inserted between both ends of the two-sided sliding members 2 and 2 in the longitudinal direction, the intermediate lubricant 4 inserted between the headers 3 and 3, A plurality of, for example, four load members 5 interposed between the intermediate slide members 4 inside the slide member 2 and both end slide members 2 and 2 are assembled into a rectangular frame by welding. An iron channel is used for these two-end sliding members 2 and the like. A plurality of, for example, four welding members 6 made of an iron square pipe are attached to the lower surfaces of the sliding members 2 and 2 and the intermediate sliding member 4 at both ends of the pallet 1 along the length direction.
[0014]
According to the present embodiment, as shown in FIG. 2, a total of four abrading members 6 located at the front and rear portions in the longitudinal direction of the sliding members 2 at both ends are prevented from being caught at the distal ends in the longitudinal direction. A cross section perpendicular to the length direction had a corrugated plate-like shape, and formed a lower side 6b whose tip reaching the lower side of the opening 6a was curved upward. The rubbing material 6 having the lower side 6b was formed by corrugating a square pipe by a press such as a press brake.
[0015]
That is, the upper mold for corrugated sheet molding, the lower mold is attached to the press brake, and the blade-shaped upper mold is applied to the center in the width direction of the upper surface of the tip of the square pipe along the length direction and pressed downward, and The center in the width direction of the upper surface of the tip portion is depressed downward along the length direction, and an upper side having a corrugated cross section perpendicular to the length direction and having a tip curved downward is formed at the tip portion. If the square pipe is turned upside down to be a ground material, a lower side 6b having a corrugated cross section and a curved upper end is obtained at the distal end of the ground material 6. Since the lower side 6b is formed in a corrugated shape, it does not protrude laterally in the cross-sectional direction.
[0016]
To give an example of a numerical example of the present invention, the dimensions of the square pipe are 45 mm in width, 75 mm in height, 300 to 1000 mm in length, and 2.3 mm in thickness, and the pressing length by the blade-shaped upper die is 20 mm, and the pressing depth is Is 10 mm. The length of the pallet 1 (the length of the sliding material at both ends) is 3000 mm and the width is 2000 mm.
[0017]
The pallet 1 of the present embodiment is configured as described above. As shown in FIG. 3, the pallet 1 is loaded with the load G, and the pallet 1 on which the load G is loaded is loaded into the container 13, and When unloading from the container 13 after transportation to the ground, even if the pallet 1 is dragged on the floor surface 14 covered with the wooden floor material of the container 13, the sliding material 6 at the front and rear portions in the longitudinal direction of the sliding material 2 at both ends of the pallet 1 can be used. Since the lower side 6b whose tip is curved upward is provided at the outer end in the length direction, the rubbing material 6 does not get caught on the floor surface 14 and the pallet 1 is placed on the floor surface 14 even if the load G is heavy. Can be smoothly moved in and out of the container 13.
[0018]
Further, since the lower side 6b of the tip of the abrading material 6 is formed by corrugating with a press brake, the lower side can be formed easily and in a short time by one pressing operation. Since the right-angled cross section is formed in a wavy shape, the lower side 6b does not protrude laterally in the cross-sectional direction, and the lower side 6b does not hinder the movement of the pallet on which the load is placed.
[0019]
In the above embodiment, a lower side 6b having a corrugated cross section and a curved upper end is formed at the outer end in the longitudinal direction of the sliding member 6 located at the front and rear portions in the longitudinal direction of the both ends sliding member 2. However, in addition to these abrading members 6, a similar lower side may be provided on the abrading members 6 at other portions of the both-end sliding member 2 or the abrading members 6 of the intermediate sliding member 4.
[0020]
Although the pallet 1 is shown as a frame, it may be a pallet having an iron plate laid on the upper surface of the frame or a box having a frame provided with side walls.
[0021]
In addition, although a case has been described in which the package is loaded on the pallet 1 and the pallet is loaded into the container 13 and transported, the present invention is not limited to this, and the transport container such as a container is not used, and the pallet is simply stored in a warehouse or the like. It can also be used when carrying luggage and transporting it with a forklift etc.Place a pallet with luggage on the floor of a warehouse or the like, and place the pallet on the pallet mounting surface The same effect is obtained when sliding.
[0022]
【The invention's effect】
As is clear from the above description, according to the transport pallet of the present invention, at least the front end portion of the sliding material at both ends in the longitudinal direction of the sliding material at both ends of the pallet is subjected to corrugating by pressing with a corrugated plate. Since the cross section perpendicular to the length direction has a corrugated plate-like shape and the lower side is curved upward, the pallets loaded with heavy loads can be dragged on the loading surface such as the container floor, even if they are dragged. Can be smoothly moved by preventing it from being caught on the mounting surface, and the lower side for preventing the caught can be formed easily and in a short time by one pressing operation.
