The conventional pallet with a water tank described above has the following features.
(1) A rectangular water tank opening is provided at the end in the length direction of the tire support surface of the pallet that continuously supports the tires of the vehicle, and the lid is fixed on the end portion in the length direction.
In a vertical circulation parking device, the pallet is supported at both ends in the length direction, on which a vehicle (for example, a passenger car) is placed. Therefore, the bending moment acting on the pallet is small at both ends in the length direction and maximum at the center. The reason why the water tank opening is provided at the end in the length direction of the pallet is that if it is provided in the center of the pallet, the reinforcing member of the water tank opening becomes large in order to secure rigidity in response to a large bending moment. be.
(2) The upper surface of the pallet is not completely horizontal and has a gradient for water to flow through the opening of the water tank. Since the pallet is supported at both ends in the length direction, when a vehicle is placed on the pallet, the center bends downward, making it difficult to secure a downward slope toward the end having the water tank opening. Therefore, conventionally, a large downward slope toward the end has been manufactured in consideration of the bending of the center when the vehicle is placed.
(3) Due to the structures of (1) and (2), the structure of the pallet is complicated, and high bending rigidity is required to suppress the bending of the pallet. Therefore, it is difficult to construct the pallet with a bent plate, and the pallet inevitably has a welded structure.

However, the above-mentioned conventional pallet with a water tank has the following problems.
(4) The opening of the water tank needs a lid, and the lid and its fixing member (for example, bolts) have irregularities on the traveling surface of the vehicle.
(5) Since it is a welded structure, it takes time and effort to manufacture, the cost is high, and the weight is large.
(6) Due to the welded structure, welding distortion is large, plating of the entire pallet is difficult, and rust is likely to occur in the welded portion and the like.

The present invention has been devised to solve the above-mentioned problems. That is, an object of the present invention is to drain water from the pallet and store it in a water tank, reduce or eliminate unevenness on the traveling surface of the vehicle, and reduce the weight and cost of the water tank. The purpose is to provide a pallet with an attachment.

According to the present invention, it is a pallet with a water tank in which both ends in the length direction are supported and a vehicle is placed on the pallets.
It is equipped with a pair of tire support surfaces that continuously support the left and right tires of the vehicle when entering and leaving the vehicle.
The tire support surface is formed horizontally and has a plurality of drain holes through which the tire can pass at the central portion in the length direction thereof.
The drain hole penetrates from the upper surface to the lower surface of the tire support surface.
Further, a water tank fixed to the lower surface of the tire support surface and storing water flowing down from the drain hole , and a water tank.
A reinforcing plate that surrounds the plurality of drain holes and is integrally connected to the lower surface of the tire support surface is provided.
A pallet with a water tank is provided at the upper end of the water tank, which is detachably attached to the reinforcing plate.

According to the above-described configuration of the present invention, a plurality of drain holes through which the tire can pass are provided in the central portion of the tire support surface in the length direction, and the water tank is fixed to the lower surface of the tire support surface. Water can be drained from the pallet through the drain hole and stored in the water tank.
Therefore, since the left and right tire support surfaces are horizontal planes having no openings other than the drain holes, the unevenness of the traveling surface of the vehicle can be significantly reduced or substantially eliminated.

In addition, since the pallet with a water tank supports both ends in the length direction (supports both ends), when a vehicle is placed on it, the center bends downward and a gradient is formed toward the center in the length direction where the water tank is located. Will be done. Therefore, since the tire support surface can be formed horizontally without a gradient at the time of manufacturing, the structure of the pallet can be simplified, and the flat plate can be manufactured with a bent plate structure, which enables weight reduction and cost reduction. Become.

Further, in the case of the bent plate structure, the strain is small as compared with the welded structure, the entire pallet can be plated, and the occurrence of rust can be significantly reduced.

4A and 4B are explanatory views showing an example of the swivel device 10, in which FIG. 4A is a plan view, FIG. 4B is a front view, and FIG. 4C is a side view.

The swivel device 10 includes a base frame 12, an elevating frame 14, and a swivel frame 16.

The foundation frame 12 is fixed to the bottom surface of the pit below the warehousing / delivery portion. The elevating frame 14 has four pairs of ball screws 14a and ball nuts 14b in this example.
The four ball nuts 14b are fixed to the four corners of the elevating frame 14, and the four ball screws 14a screwed with the four ball nuts 14b extend vertically and the lower ends are rotatably fixed to the foundation frame 12. The four ball screws 14a are synchronized with each other by a chain and a sprocket, and are rotationally driven by an elevating drive device (not shown). By this rotation, the elevating frame 14 can move up and down while maintaining the horizontal position.

A swivel ring 15 is provided between the upper end of the elevating frame 14 and the swivel frame 16, so that the swivel drive device 15a can horizontally swivel the swivel frame 16 around its rotation center Z.

The swivel frame 16 includes a central horizontal member 16a extending horizontally from the rotation center Z on both sides in the length direction of the vehicle C, and a pair of end horizontal members 16b fixed to both ends of the central horizontal member 16a and extending in the width direction.

With the above-described configuration, by raising the swivel frame 16 in the state of FIG. 3, the pallet 20 with a water tank on the cage located at the warehousing / delivery portion can be replaced from the cage 8 to the swivel frame 16. Further, by horizontally turning the turning frame 16 at the ascending position, the front and rear of the vehicle C of the pallet 20 with a water tank can be reversed.
Further, by lowering the swivel frame 16 as it is after reversing, the pallet 20 with a water tank can be mounted on the cage and the swivel frame 16 can be retracted below the cage 8.

FIG. 5 is a view taken along the line BB of FIG. 3, and the pallet 20 with a water tank is omitted.
As shown in this figure, the vehicle mounting portion 8b and the suspension frame portion 8c of the cage 8 have the form of a rectangular frame that is long in the length direction of the vehicle C in a plan view.
The swivel frame 16 is located inside the rectangular frame (vehicle mounting portion 8b and suspension frame portion 8c) of the cage 8 so as not to interfere with the vehicle mounting portion 8b and the suspension frame portion 8c when the swivel frame 16 is raised.
Further, the cage 8 has support plates 8e at four corners of a rectangular frame composed of a vehicle mounting portion 8b and a suspension frame portion 8c.

FIG. 6A is a view taken along the line BB of FIG. 3, showing the pallet 20 with a water tank without omitting it.
As shown in this figure, the support plate 8e detachably supports both ends of the pallet 20 with a water tank in the length direction.
FIG. 6B shows the bending shape of the pallet 20 with a water tank.
In a state where both ends in the length direction are supported by the support plate 8e, the center of the pallet 20 with a water tank bends downward when the vehicle C is placed on the pallet 20 with a water tank, as shown in FIG. A gradient is formed toward the central portion of the tank 26 in the length direction.

As shown in FIG. 6A, the support plate 17 of the swivel frame 16 is located inside the support plate 8e. Therefore, the deflection of the pallet 20 with a water tank in the state supported by the support plate 17 is smaller than that in the state supported by the support plate 8e, but the center is similarly bent downward and a certain length of the water tank 26. A gradient is formed towards the center of the direction.

7A and 7B are explanatory views of a pallet 20 with a water tank, where FIG. 7A is a plan view and FIG. 7B is a side view.
In FIG. 7A, the pallet 20 with a water tank includes a pair (upper and lower in the figure) of tire support surfaces 22. The tire support surface 22 is formed horizontally and continuously supports the left and right tires of the vehicle C at the time of loading and unloading.
Further, the tire support surface 22 is provided at the central portion in the length direction thereof, penetrates from the upper surface to the lower surface, and has a plurality of drain holes 24 through which the tire can pass.
In FIG. 7B, the pallet 20 with a water tank is further provided with a water tank 26 which is fixed to the lower surface of the central portion in the length direction and collects water flowing down from the drain hole 24.

FIG. 8 is an enlarged view of part C of FIG. 7A and a view taken along the line DD.

In FIG. 8A, the drain hole 24 is set to reduce the missing cross-sectional area of the roadway (tire support surface 22). In other words, the section coefficient including the water tank 26 in the cross section passing through the water tank 26 and orthogonal to the length direction is set to be larger than the section coefficient of the portion without the water tank 26.
That is, in FIG. 8B, the outer peripheral portion of the water tank 26 is attached to the tire support surface 22 from below by the bolt 26a, and the cross-sectional coefficient including the water tank 26 is larger than the cross-sectional coefficient of the portion without the water tank 26. It has become.

As shown in FIG. 8C, the reinforcing frame 25a integrally connected to the lower surface of the tire support surface 22 may be integrally connected by welding, for example.
In this case, the outer peripheral portion of the water tank 26 is attached to the reinforcing frame 25a from below by the bolt 26a.

The drain hole 24 in FIG. 8 is preferably a circular hole having an inner diameter of 4 to 12 mm, for example, but may have other shapes.

In FIGS. 8B and 8C, the water tank 26 has a drainage pipe 26b fixed to the bottom thereof. Further, drainage is performed at the warehousing / delivery section via a drainage tube (not shown) connected to the drainage pipe 26b. This drainage mechanism is the same as the conventional one.

As shown in FIG. 8B, the pallet 20 with a water tank has rigidity-added portions 23a and 23b bent above the tire support surface 22 on the inside and outside of the tire support surface 22 in the width direction.
In this example, the tire support surface 22 and the rigidity adding portions 23a and 23b connected to the tire support surface 22 have a bent plate structure obtained by bending a single flat plate.
The rigidity-added portions 23a and 23b are provided with a gradient so that water on the rigidity-added portions 23a and 23b flows to the tire support surface 22.

That is, in the pallet 20 with a water tank, a pair of bent plate members (which have a tire support surface 22 and rigidity-added portions 23a and 23b, respectively) obtained by bending a single flat plate are joined along the center line in the width direction. It is formed by welding.
With this configuration, the welded portion can be significantly reduced and the distortion of the pallet can be significantly reduced.

Further, the tire support surface 22 of the pallet 20 with a water tank is plated. In this example, the pallet 20 with a water tank has a bent plate structure, has less distortion than a welded structure, and can easily plate the entire pallet, so that the occurrence of rust can be significantly reduced.

FIG. 9 is a diagram similar to FIG. 8 showing another form of the pallet 20 with a water tank.
In FIG. 9A, the drain hole 24 is an elongated slit hole extending in the width direction. The width of the slit hole is, for example, an inner diameter of 4 to 12 mm.

In FIG. 9B, the pallet 20 with a water tank has a reinforcing plate 25b integrally connected to the lower surface of the tire support surface 22. The "integral bond" should be by welding.
The reinforcing plate 25b surrounds a plurality of drain holes 24, and the drain holes 24 penetrate the tire support surface 22 and the reinforcing plate 25b.
Further, in this example, the outer peripheral portion of the upper end of the water tank 26 is detachably attached to the reinforcing plate 25b from below by a bolt 26a.

With this configuration, even if the drain hole 24 is an elongated slit hole extending in the width direction, the cross-sectional coefficient in the cross section that passes through the water tank 26 and is orthogonal to the length direction can be increased due to the presence of the reinforcing plate b25. Further, since the drain hole 24 is an elongated slit hole extending in the width direction, water can be efficiently drained from the upper surface of the tire support surface 22 to the water tank 26.

In FIG. 9C, there is no reinforcing plate 25b in FIG. 9B, and the outer edge of the upper end of the water tank 26 is integrally connected to the lower surface of the tire support surface 22. This "integral bond" is best done by welding.
With this configuration, even if the drain hole 24 is an elongated slit hole extending in the width direction, the outer edge of the upper end of the water tank 26 is integrally connected. Can be increased. Further, since the drain hole 24 is an elongated slit hole extending in the width direction, water can be efficiently drained from the upper surface of the tire support surface 22 to the water tank 26.

According to the above-described embodiment of the present invention, a plurality of drain holes 24 through which the tire can pass are provided in the central portion of the tire support surface 22 in the length direction, and the water tank 26 is located on the lower surface of the tire support surface 22. Since it is fixed, water can be drained from the pallet through the drain hole 24 and stored in the water tank 26.
Therefore, since the left and right tire support surfaces 22 are horizontal planes having no openings other than the drain holes, the unevenness of the traveling surface of the vehicle C can be significantly reduced or substantially eliminated.

Further, since the pallet 20 with a water tank is detachably supported (supported at both ends) at both ends in the length direction by the cage 8, when the vehicle C is placed on the pallet 20, the center bends downward and the length of the water tank 26 is present. A gradient is formed towards the central part in the longitudinal direction. Therefore, since the tire support surface 22 can be formed horizontally without a gradient at the time of manufacturing, the structure of the pallet can be simplified, and the flat plate can be manufactured with a bent plate structure, which enables weight reduction and cost reduction. It becomes.

Further, since the tire support surface 22 and the rigidity-added portions 23a and 23b connected to the tire support surface 22 have a bent plate structure obtained by bending a single flat plate, the strain is smaller than that of the welded structure, and the entire pallet can be plated. , The occurrence of rust can be significantly reduced.

It should be noted that the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the gist of the present invention.
