Description

[Detailed Description of the Invention] A. Field of Industrial Application The present invention relates to a pallet device used for storing and transporting pipes, rods, etc. B. Prior Art Conventionally, U-shaped pallets have been used for storing and transporting pipes, rods, etc. For example, Japanese Patent Publication No. 56-13436 proposed a U-shaped stock rack with a suspension plate bent inward and equipped with a hook. This stock rack is made up of two U-shaped parts connected as appropriate. However, it is customary for pallets to be stacked so that they do not occupy a large area for storing pipes, etc.; however, when stacking pallets, it is necessary to support the upper strain rack in narrow areas such as side members. Must be. C. Problems to be solved As a result, there is a high risk of slipping and falling due to unforeseen disasters such as earthquakes, operational errors during loading, slinging, lifting, etc. This poses a danger to people, which is a problem in terms of ensuring safety. Therefore, it is necessary to take measures to prevent pallets from falling and falling. D. Means for solving the problem Therefore, in the present invention, the pallet, especially when stacking the pallet, can be stably placed and prevented from overturning, and the upper end of the side edge of the U-shaped pallet is A cylindrical hook with an appropriate height is protruded from the base, and an appropriate number of engagement holes are bored in the hook, and the upper end of the lever, which is movable up and down, is positioned in the engagement groove of the hook. A claw piece engaged with the lever is made to be able to come in and out through a hole provided at the lower end of the side edge of the letter-shaped pallet, and a claw piece that is engaged with the lever can be freely engaged and disengaged from the engagement hole, and a hook piece is provided at the lower end of the side edge. It is characterized in that an insertion part having a fitting part is formed. E. Embodiment 1 is a U-shaped pallet, which is composed of a substrate 2 and side edges 3 , 3 standing upright at both ends thereof.
Although the substrate 2 is illustrated as a disk body formed to an appropriate width,
It may also be constructed of girders, ribs, etc. side edge 3
has a hook 5 fixed to the top plate 4 at its upper end. Reference numeral 6 denotes an insertion part formed at the lower part of the side edge 3, which has an appropriate height of the hook 5, partition plates 19, 19, an inner plate 20, and a partition into which the base 5' formed in the shape of a rectangular cylinder or the like fits. Fitting portion 22 partitioned by plate 21
The upper part is open. Reference numeral 7 denotes a locking device, which is composed of a lever 8, a hanger 9, and a claw 10. The upper end of the lever 8 is supported through a long hole 12 provided in the center by a bolt 13 fixed to the side edge 3 or the hook 5 (in some cases, the bolt 13 is not used,
A method that allows the lever to move up and down smoothly may also be used. ) located at the lower end of the engagement groove 11 of the hook 5,
The upper end of the hanger 9 is fixed to its lower end.
The hanger 9 is bifurcated into two, and claws 10 are engaged with each of the bifurcated ends. The claw 10 has one end pivoted 14 on the side edge 3, and a pin 15 provided in the middle.
is inserted into an elongated hole 16 formed in the hanger 9, and its lower part can be freely taken in and out through a hole 17 provided at the lower end of the side edge 3 . Reference numeral 18 denotes an engagement hole provided at the upper end of the side edge 3 at a position corresponding to the hole 17 at the lower end.
Next, the method of use and operation will be explained. U-shaped pallets 1 , 1 are placed at appropriate intervals, and desired pipes, steel materials, etc. to be stored or moved are placed across them. Hook the rope or lifting rod using the usual method 5
Hang it on the rail and place it at the desired position. Although they are sometimes used in a single layer like this, they are usually stacked two or three times on top of each other for efficient storage. When loading the second and subsequent stages, the hook 5 of the lower U-shaped pallet 1 fits into the insertion part 6 formed at the lower part of the side edge 3 to determine its position and prevent lateral movement. prevent. In addition, if the installation location of the U-shaped pallet 1 is determined in advance, by providing a protrusion of the same size as the hook 5 on the floor surface, it can be firmly fixed from the first stage. Depending on the object to be conveyed, a plurality of U-shaped pallets may be connected by a connecting member and used as a single U-shaped pallet. When the lock device 7 is provided, when the rope or the lifting rod is engaged with the engagement groove 11 of the hook 5, the lever 8 is also raised at the same time, and the long hole 16 of the hanger 9 provided at the lower end of the lever 8 is raised at the same time. pin 15 engaged with
Rotate and raise the claw 10 through the side edge 3.
It is pulled in through the hole 17 and stored. When placing it on the floor or other side edge 3 , if the rope or lifting rod is removed from the hook 5, the lifting force on the upper end of the lever 8 disappears, and the lever 8 and hanger 9 are lifted by their own weight. It descends and rotates the claw 10 to project from the hole 17. At this time, the claw 10 engages with the engagement groove 18 provided on the side edge 3 of the lower U-shaped pallet 1 . Therefore, the upper and lower U-shaped pallets 1 , 1 are locked without being displaced. When installing the U-shaped pallet 1 at the bottom, if an engagement groove is provided on the floor,
It is possible to stably prevent it from falling from the bottom step. G. Effects of the invention According to the invention as described above, hooks are protruded from the upper ends of the side edges of the U-shaped pallet, engagement holes are further provided, and the upper ends of the side edges are fitted with the bases of the hooks. When the U-shaped pallets are stacked, the lower hooks fit into the fitting portions formed on the side edges of the upper U-shaped pallets.
In addition to being able to determine its position, the upper and lower U-shaped pallets are engaged and fixed, preventing displacement, slipping, etc., and preventing falling and collapsing.
