The pallet with anti-vibration device of this embodiment is used as a mounting object 7 for transporting the fuel cell unit 7a. Since the reformer of the fuel cell unit 7a has ceramic parts and has a structure that is easily damaged, it is preferable to transport the fuel cell unit 7a on a pallet with a vibration isolator.

As shown in FIG. 1, the pallet with a vibration isolator includes a pallet body 1, a plurality of vibration isolators 5 mounted on the pallet body 1, and a support 6 spanned on the plurality of vibration isolators 5. It has.

The pallet body 1 constitutes the main body of the pallet with anti-vibration equipment. The pallet body 1 is resin-molded with a synthetic resin. The pallet body 1 of the present embodiment includes a first pallet 2 and a second pallet 3, and the first pallet 2 and the second pallet 3 are separated from each other in a state of not being connected to each other.

Hereinafter, the direction in which the first pallet 2 and the second pallet 3 are arranged is defined as the front-rear direction, and the direction in which the first pallet 2 (second pallet 3) extends is defined as the left-right direction. Further, since the first pallet 2 and the second pallet 3 have the same structure, the description of the pallet body 1 mainly describes the first pallet 2 and omits overlapping description.

The first pallet 2 includes a first divided body 21 and a second divided body 22 as a plurality of divided bodies, and is configured to be able to be divided into a plurality of divided bodies 21 and 22. The second pallet 3 also has the same structure as the first pallet 2, but the member corresponding to the first divided body 21 is defined as the third divided body 31, and the member corresponding to the second divided body 22 is the fourth. It is defined as the divided body 32. That is, the third divided body 31 has the same structure as the first divided body 21, and the fourth divided body 32 has the same structure as the second divided body 22.

The main body of the first divided body 21 is composed of a rectangular box-shaped main body 41 extending in the left-right direction. A fork insertion portion 42 is formed at the central portion of the main body portion 41 and at the central portion in the vertical direction. The fork insertion portion 42 penetrates the main body portion 41 in the front-rear direction, and is configured so that a forklift claw used during transportation work can be inserted.

The second divided body 22 is also mainly composed of a rectangular box-shaped main body 41 extending in the left-right direction. Similarly, a fork insertion portion 42 is formed in the central portion of the main body portion 41 and in the central portion in the vertical direction.

The first divided body 21 has a pair of locking portions 43 formed on both end faces in the left-right direction of the main body portion 41. Each locking portion 43 is composed of a fitting convex portion 43a formed so as to project from an end surface of the main body portion 41 in the left-right direction. The fitting convex portion 43a is formed so that the width in the front-rear direction becomes wider as it is located on the tip side in the protruding direction. The fitting convex portion 43a is formed over the entire length of the main body portion 41 in the vertical direction, and is formed in a uniform cross section in the vertical direction.

In the second divided body 22, a pair of locked portions 44 that engage with the locking portion 43 are formed on both end surfaces of the main body portion 41 in the left-right direction. As shown in FIG. 2, the locked portion 44 is composed of a fitting recess 44a formed so as to be recessed from the left-right end surface of the main body portion 41. The fitting recess 44a is formed so that the width in the front-rear direction becomes wider as it is located on the inner side in the depth direction. The fitting recess 44a is formed over the entire length of the main body 41 in the vertical direction, and is formed in a uniform cross section in the vertical direction. By inserting the fitting convex portion 43a along the vertical direction, the fitting concave portion 44a can regulate the relative movement of the fitting convex portion 43a in the front-rear direction and the left-right direction.

As shown in FIG. 1, a storage recess 47 is formed in each of the first divided body 21 and the second divided body 22. The accommodating recess 47 of the first division body 21 is formed on the upper surface of the end portion on the second division body 22 side. Further, the accommodation recess 47 of the second divided body 22 is formed on the upper surface of the end portion on the first divided body 21 side.

As shown in FIG. 3, each storage recess 47 is formed to be larger than the vibration isolator 5, and is configured to be capable of accommodating the vibration isolator 5. The accommodation recess 47 formed in the first divided body 21 is, for example, a vibration isolator 5 attached to the second divided body 22 when the upper surfaces 49 are overlapped with each other so as to face each other with respect to the second divided body 22. Is configured to be housed. At this time, the upper surfaces 49 of the pair of divided bodies 21 and 22 come into contact with each other in a planar manner.

As described above, the first divided body 21 of the present embodiment can be overlapped with the second divided body 22 in the vertical direction, but it is preferably overlapped with the third divided body 31 having the same structure. Further, it is preferable that the second divided body 22 is overlapped with the fourth divided body 32 having the same structure.

As a result, as shown in FIG. 4, the first divided body 21 and the third divided body 31 are overlapped (the set in which the first divided body 21 and the third divided body 31 are overlapped is referred to as the first polymer 45. ), The second divided body 22 and the fourth divided body 32 are overlapped (the set in which the second divided body 22 and the fourth divided body 32 are overlapped is referred to as the second polymer 46), so that the locking portion 43 is formed. The locked portion 44 is continuous over the entire length of the first polymer 45 in the vertical direction, and the locked portion 44 is continuous over the entire length of the second polymer 46 in the vertical direction. Therefore, the first polymer 45 and the second polymer 46 can be connected to each other via the locking portion 43 and the locked portion 44.

Further, the pallet with anti-vibration device of the present embodiment has a movement restricting unit 48 that regulates movement along the upper surfaces of the divided bodies in a state where the upper surfaces of the pair of divided bodies are overlapped with each other. As a result, when the divided bodies are overlapped with each other, it is possible to prevent them from shifting from each other. Therefore, for example, during transportation in the overlapped state, the divided bodies rattle and the vibration isolator 5 is damaged or deteriorated. It can be suppressed.

The movement control unit 48 of the present embodiment is composed of a storage recess 47. The storage recess 47 has an inner peripheral surface 471 configured to surround the vibration isolator 5 in a state where the vibration isolator 5 is accommodated. The inner peripheral surface 471 is in close contact with the outer surface of the vibration isolator 5 in a state where the vibration isolator 5 is housed. As a result, when the vibration isolator 5 is accommodated in the accommodation recess 47, the accommodation recess 47 and the vibration isolator 5 are positioned with each other, and the relative movement along the upper surface of the pair of divided bodies is restricted.

As shown in FIG. 1, at least one vibration isolator 5 is attached to each of the divided bodies 21, 22, 31 and 32. The pallet with vibration isolator of the present embodiment includes a plurality of vibration isolators 5, and the plurality of vibration isolators 5 are attached one-to-one to a plurality of divided bodies 21, 22, 31, 32. ing. Each anti-vibration tool 5 is attached to the upper surface of an end portion (outer end portion) on the side opposite to the connected side of the divided bodies 21, 22, 31 and 32.

The vibration isolator 5 is fixed to the fixed plate portion 51 fixed to the upper surface 49 of the divided bodies 21, 22, 31 and 32, the elastic portion 52 fixed to the upper part of the fixed plate portion 51, and the upper part of the elastic portion 52. It is provided with a holding portion 53. The elastic portion 52 is made of, for example, a solid columnar rubber. The holding portion 53 includes a disc portion 54 fixed to the elastic portion 52 and a bolt portion 55 protruding upward from the disc portion 54.

The pair of anti-vibration tools 5 are configured to be able to support the mounting object 7. Here, since the holding portion 53 that supports the mounting object 7 is connected to the fixing plate portion 51 via the elastic portion 52, the pallet body 1 fixed to the fixing plate portion 51 vibrates. However, it is possible to suppress the vibration from being transmitted to the mounting object 7.

In the first pallet 2, a support 6 is bridged between the vibration isolator 5 of the first divided body 21 and the vibration isolator 5 of the second divided body 22. Further, in the second pallet 3, the support 6 is also bridged between the vibration isolator 5 of the third divided body 31 and the vibration isolator 5 of the fourth divided body 32. Each support 6 is configured to mount a mounting object 7, and each support 6 can support the mounting object 7. Each support 6 is detachably fixed by a bolt portion 55 of the vibration isolator 5. The support 6 extends in the left-right direction, and is made of, for example, C-shaped steel.

As shown in FIG. 5, for example, a fuel cell unit 7a manufactured in a manufacturing factory is placed on a support 6 and packed with a packing material 8 in a pallet with a vibration isolator having such a configuration. It is transported to the work site where it is transported. After being transported to the work site, the fuel cell unit 7a is removed from the pallet with the vibration isolator.

The pallet with the anti-vibration device from which the fuel cell unit 7a is lowered is disassembled into a state suitable for transportation. The operator removes the support 6 from the vibration isolator 5, disassembles the first division 21 and the second division 22, and divides the third division 31 and the fourth division 32.

Next, the operator superimposes the first divided body 21 and the third divided body 31 so that the upper surfaces face each other, and causes the second divided body 22 and the fourth divided body 32 to face each other. (See Fig. 3). At this time, the vibration isolator 5 attached to one of the divided bodies is accommodated in the other accommodating recess 47 (see FIG. 4). In this state, since the vibration isolator 5 is covered with the inner peripheral surface 471 of the accommodation recess 47, it is not irradiated with direct sunlight or ultraviolet rays even if it is left outdoors.

Next, the worker loads the stacked divided bodies on a truck bed or the like and takes them back to the manufacturing factory or the like. At this time, since the divided bodies are stacked exactly in the vertical direction with the vibration isolator 5 housed in the storage recess 47, there is no wasted space and the transportability is good. Moreover, since the pallet body 1 of the present embodiment is made of synthetic resin, it is lighter than the conventional wooden pallet and can carry more.

The pallet with anti-vibration equipment brought back to the factory connects the locking portion 43 of the first divided body 21 and the locked portion 44 of the second divided body 22 and attaches the support 6 to the mounted object 7. Can be placed so that it can be transported.
