Description

  The present invention relates to a water collection structure for a pallet provided in a parking apparatus.

  The parking device is a mechanical device that moves the pallet on which a vehicle is loaded from a warehousing position to a parking position at the time of warehousing, and moves from the parking position to the leaving position at the time of warehousing. Such a parking device includes, for example, a pallet circulation type (for example, Patent Document 1 below). In the pallet circulation type, a plurality of pallets are circulated along a predetermined circulation path including a warehouse position or a warehouse position. Move.

  When the above-described parking device is installed in an area where there is a lot of snow, when a vehicle to which snow is attached is loaded on the pallet, this snow melting water falls on the top surface of the pallet. In order to collect such snow melting water, a water collecting structure is provided on the pallet.

  FIG. 6 shows a conventional example of a water collection structure. 6A is a plan view of the pallet 21, and FIG. 6B is a cross-sectional view taken along the line BB of FIG. 6A. In FIG. 6, a water collection part (water collection tank) 25 is provided below the pallet upper surface 23. A lid member 29 is attached to the opening 27 of the water collecting portion 25. A hole 29 a is formed in the lid member 29, and the hole 29 a allows the pallet upper surface 23 and the water collecting portion 25 to communicate with each other. With this structure, the snow melting water that has fallen from the vehicle to the pallet upper surface 23 flows into the water collecting portion 25 through the hole 29a. The pallet upper surface 23 includes a central portion 23a and a concave wheelway 23b spaced from side to side across the central portion 23a.

Such a water collection structure is described, for example, in Patent Documents 2 and 3 below.

However, even with the water collection structure of FIG. 6, the drainage is not sufficient, and water tends to accumulate on the top surface of the pallet. Therefore, there is a possibility that rust is easily generated on the pallet.
For example, if a large amount of snow is attached to a vehicle loaded on the pallet, a large amount of snow melting water is generated on the top surface of the pallet. Particularly in such a case, if the drainage is insufficient, rusting is likely to occur.

  Therefore, an object of the present invention is to improve drainage on the top surface of the pallet and make the pallet difficult to rust.

In order to achieve the above object, the present invention is a water collection structure for a pallet provided in a parking device,
The parking device is configured to move the pallet on which a vehicle is loaded from a storage position to a parking position, and to move from the parking position to a departure position.
The pallet has a water collecting part that collects water on the upper surface of the pallet and is located at a lower part of the upper surface of the pallet, and an opening that leads to the water collecting part is formed on the upper surface of the pallet. Is attached,
The lid member is formed with a large number of through holes penetrating vertically .
The lid member is attached to the top surface of the pallet so as not to cover the end on the other end side in the front-rear direction of the opening as a gap,
Water that has flowed on the pallet upper surface from the other end in the front-rear direction toward the lid member flows into the water collecting portion through the gap without staying on the pallet upper surface.

In the pallet water collecting structure of the present invention described above, the lid member is formed with a large number of through holes penetrating vertically, so that even if a large amount of snow melting water is generated on the pallet top surface, Without accumulating, a large amount of snow melting water can be poured into the water collecting section through many through holes. Therefore, drainage on the top surface of the pallet is improved, and the pallet is hardly rusted.
As a result, the number of maintenance operations against rust such as repainting of the pallet is reduced, and the life of the pallet is extended.

According to a preferred embodiment of the present invention, the opening is provided on one end side in the front-rear direction on the top surface of the pallet,
The upper surface of the pallet is slightly inclined downward from the horizontal direction from the other end in the front-rear direction to the one end in the front-rear direction on the upper surface of the pallet .

  Thus, the lid member is attached to the top surface of the pallet so as not to cover the end of the opening on the other end side in the front-rear direction as a gap, and from the other end side in the front-rear direction, Since at least a part of the water that has flowed on the pallet upper surface to the side flows into the water collecting portion through the gap, the water on the pallet upper surface can flow more effectively to the water collecting portion.

In particular, the gap is effective when the top surface of the lid member attached to the opening is slightly higher than the top surface of the pallet due to its structure. In this case, even if a small amount of water flowing on the pallet upper surface from the other end side in the front-rear direction to the lid member side, when reaching the position of the gap, the gap falls to the water collecting part, Water does not accumulate in front of the lid member. On the other hand, if there is a large amount of water flowing on the top surface of the pallet from the other end in the front-rear direction toward the lid member, a large amount of water flows into the water collection section through the gaps and the numerous through holes.
Therefore, even if a small amount or a large amount of water falls from the vehicle to the pallet top surface, water hardly accumulates on the pallet top surface, and the drainage performance of the pallet top surface is greatly improved.

According to a preferred embodiment of the present invention, the lid member is placed on the top surface of the pallet with a rubber material up and down,
The lid member is fixed to the top surface of the pallet only by a static frictional force due to the rubber material.

  Thus, the lid member is placed on the top surface of the pallet with the rubber material up and down, and the lid member is fixed on the top surface of the pallet only by the static frictional force of the rubber material, Not only can the lid member be removably fixed to the opening, but also the clearance can be secured by the fixing, and the rubber plate prevents the coating and plating on the top surface of the pallet from being peeled off. A synergistic effect is obtained.

According to a preferred embodiment of the present invention, on the top surface of the pallet, a water return portion is provided on one end side in the front-rear direction of the opening,
Of the water that has flowed on the top surface of the pallet from the other end in the front-rear direction to the lid member, the water that has passed through the lid member is returned to the lid member by the water return portion. .

  Thus, of the water that has flowed on the top surface of the pallet from the other end in the front-rear direction toward the lid member, the water that has passed through the lid member is returned toward the lid member by the water return portion. Therefore, the water on the top surface of the pallet can be made to flow more effectively to the water collecting section.

  According to the present invention described above, drainage on the top surface of the pallet is improved and the pallet is less likely to rust.

  The best mode for carrying out the present invention will be described with reference to the drawings. In addition, the same code | symbol is attached | subjected to the common part in each figure, and the overlapping description is abbreviate | omitted.

  FIG. 1 is a plan view showing a pallet 1 of a parking apparatus to which the pallet water collecting structure of the present invention can be applied.

  The pallet 1 shown in FIG. 1 is moved from the storage position to the parking position when the vehicle is received and moved from the parking position to the departure position when the vehicle is released. This parking apparatus may be of a pallet circulation type described in Patent Document 1, for example.

  2 is a partially enlarged view of FIG. 1, FIG. 3 is a sectional view taken along line III-III in FIG. 2, and FIG. 4 is a sectional view taken along line IV-IV in FIG.

As shown in FIGS. 2 to 4, the pallet 1 has a water collection section (collection tank) 5 that is located below the pallet upper surface 3 and collects water on the pallet upper surface 3. The pallet upper surface 3 is formed with an opening 7 leading to the water collecting portion 5, and a lid member 9 is attached to the opening 7. In addition, the pallet 1 is obtained by coating the surface of a metal material such as iron. Note that a discharge pipe (not shown) for discharging the water in the water collection unit 5 may be connected to the water collection unit 5.

  In the example of FIG. 1, the pallet upper surface 3 has a central portion 3a and a wheel path 3b. The wheel path 3b is a bottom surface of a concave portion provided to be separated from the left and right with the central portion 3a interposed therebetween. The wheel path 3b extends from one end in the front-rear direction of the pallet 1 (lower end in FIG. 1) to the other end in the front-rear direction (upper end in FIG. 1). In this example, when the pallet 1 is at the loading / unloading position that serves as both the loading position and the unloading position, the left and right tires of the vehicle (from a not-shown roadway) respectively move to the left and right wheels when the vehicle is self-propelled from the upper side in FIG. The vehicle enters the road 3b, and the vehicle self-propells to the upper side in FIG. 1 so that the tires of the vehicle can get on the wheel road 3b (to a vehicle road not shown).

  According to the present embodiment, the lid member 9 is formed with a large number of through holes 9a penetrating vertically. In the example of FIG. 2, the lid member 9 is a lattice-shaped grating having a large number of through holes 9 a. Preferably, the lid member 9 is made of a rust preventive material such as molten zinc or molten tin so as to prevent rust, and is plated on a metal such as iron or steel.

  Also, the pallet top surface 3 (in the example of FIG. 1, in the example of FIG. 1, the wheel is downward) from the horizontal direction toward the front / rear direction one end side (lower side in FIG. 1) from the other front / rear direction side (upper side in FIG. 1). The path 3b) is slightly inclined (see FIG. 3). Therefore, in FIG. 1, the water on the wheel path 3 b located on the other end side in the front-rear direction from the lid member 9 naturally flows on the wheel path 3 b toward the lid member 9.

  Preferably, the water collecting structure 10 is provided with a gap 11, a rubber material 13, and a water return portion 15.

The gap 11 is as shown in FIGS. That is, the lid member 9 is attached to the pallet upper surface 3 so as not to cover the end of the opening 7 at the other end in the front-rear direction (left side in FIG. 3) as the gap 11. Therefore, at least a part of the water that has flowed from the other end side in the front-rear direction toward the lid member 9 on the pallet upper surface 3 (in this example, the wheel path 3b) passes through the gap 11 to the water collecting portion 5. It flows in (see the arrow in FIG. 3).
In particular, the gap 11 is effective when the upper surface of the lid member 9 attached to the opening 7 is slightly higher than the pallet upper surface 3 (in this example, the wheelway 3b) due to the structure. In the present embodiment, as shown in FIGS. 3 and 4, the upper surface of the lid member 9 is slightly higher than the pallet upper surface 3 (that is, the wheelway 3 b) that defines the gap 11. Therefore, even if a small amount of water has flown from the other end in the front-rear direction toward the lid member 9 and reaches the position of the gap 11, the gap 11 falls to the water collecting portion. 5, water does not accumulate on the pallet upper surface 3 in front of the lid member 9. On the other hand, if there is a large amount of water flowing from the other end in the front-rear direction toward the lid member 9 on the pallet upper surface 3, a large amount of water is collected through the gap 11 and the numerous through holes 9a. It flows into part 5.

FIG. 5A shows a case where the rubber material 13 is provided for the configuration of FIG. FIG. 5B is an enlarged view of a portion B indicated by a broken line in FIG.
As shown in FIG. 5, the lid member 9 is placed on the pallet upper surface 3 with a rubber material 13 formed of rubber up and down. The rubber material 13 is provided between the left end portion 9b of the lid member 9 and the wheel path 3b, and between the right end portion 9c of the lid member 9 and the wheel path 3b. The lid member 9 may be fixed to the pallet upper surface 3 only by such a static frictional force caused by the rubber material 13. This static friction force may act on both or one side between the lid member 9 and the rubber material 13 and between the rubber material 13 and the wheel path 3b. For example, when the rubber material 13 is coupled to the lid member 9 or the wheel path 3b by a coupling means such as an adhesive, the static frictional force is generated between the wheel path 3b and the rubber material 13 or the rubber material 13 And the lid member 9.
A plurality of rubber members 13 are provided between the left end portion 9b of the lid member 9 and the wheel path 3b at intervals in the front-rear direction along the left end portion 9b of the lid member 9, and the right end portion of the lid member 9 is provided. A plurality may be provided between the right end portion 9a of the lid member 9 and the wheel path 3b at intervals in the front-rear direction along 9a. In this case, as shown in FIG. 5, the rubber material 13 may be a U-shaped member that is fitted to the edge of the plate-like portion 17 of the pallet 1 that defines the opening 7. Thereby, the rubber material 13 can be attached to the edge of the plate upper portion 17.
The upper surface of the plate-like portion 17 is a part of the wheel path 3b. Further, when a plurality of rubber materials 13 are provided at intervals as described above, water on the wheelway 3b flows in the left-right direction in FIG. 5 between the rubber materials 13 adjacent in the front-rear direction. The water can flow into the water collecting section 5. This also increases drainage.

  The water return part 15 is shown in FIG. 2, FIG. As shown in FIGS. 2 and 3, on the pallet top surface 3, a water return portion 15 is provided on one end side in the front-rear direction of the opening 7 (right side in FIG. 3). Of the water that has flowed on the pallet upper surface 3 from the other end in the front-rear direction toward the lid member 9, the water that has passed through the lid member 9 passes through the lid 15 by the water return surface 15 a of the water return portion 15. Returned to the member 9. The water return surface 15a extends in the left-right direction (the left-right direction in FIG. 2) over the entire left-right width of each wheel path 3b, thereby blocking the region where water tries to pass in the front-rear direction in the wheel path 3b. Preferably, the lower end 15b of the water return portion 15 is disposed at the same position as the one end in the front-rear direction of the lid member 9, and is in watertight contact with the wheelway 3b. Thereby, the water returned by the water return surface 15a is guided to the water collection part 5 through the through-hole 9a as it is. Therefore, drainage is further enhanced. In addition, in the example of FIG. 3, the water return surface 15a is a surface extending in a direction inclined from the vertical direction, but may be a surface extending in the vertical direction.

  According to the water collecting structure 10 of the pallet 1 according to the embodiment of the present invention described above, the following effects (1) to (4) are obtained.

(1) Since the lid member 9 has a large number of through holes 9a penetrating vertically, even if a large amount of snow melting water is generated on the pallet top surface 3, a large amount of water is not collected on the pallet top surface 3. Snow melting water can be poured into the water collecting section 5 through a large number of through holes 9a. Therefore, the drainage of the pallet upper surface 3 is improved, and the pallet 1 is hardly rusted. As a result, the number of times of maintenance against rust such as repainting of the pallet 1 is reduced, and the life of the pallet 1 is extended.

(2) The lid member 9 is attached to the pallet upper surface 3 so as not to cover the end of the opening 7 on the other end side in the front-rear direction as the gap 11, and from the other end side in the front-rear direction Since at least a part of the water that has flowed on the pallet upper surface 3 toward the lid member 9 flows into the water collecting section 5 through the gap 11, the water on the pallet upper surface 3 is collected more effectively. It can flow to the water part 5.
In particular, when the upper surface of the lid member 9 attached to the opening 7 is slightly higher than the pallet upper surface 3 due to the structure, the gap 11 is effective as described above. Water hardly accumulates and the drainage performance of the pallet top surface 3 is greatly improved.

(3) The lid member 9 is placed on the pallet upper surface 3 with the rubber material 13 up and down, and the lid member 9 is fixed to the pallet upper surface 3 only by a static friction force by the rubber material 13. Therefore, not only can the lid member 9 be removably fixed to the opening 7 but also the clearance 11 can be secured by being fixed, and the rubber material 13 can be used to secure the top surface of the pallet. Thus, a synergistic effect is obtained that prevents the coating or plating of 3 from being peeled off.

(4) Of the water that has flowed through the top surface 3 of the pallet from the other end in the front-rear direction to the side of the lid member 9, the water that has passed through the lid member 9 is passed through the lid member 9 by the water return portion 15. Therefore, the water on the pallet upper surface 3 can be made to flow to the water collecting part 5 more effectively.

  The present invention is not limited to the above-described embodiment, and various changes can be made without departing from the scope of the present invention.

  For example, in the above-described embodiment, the pallet 1 may be a plating pallet in which a surface is plated with a material that is hard to rust such as molten zinc or molten tin on a material such as iron. In this case, the pallet 1 becomes more difficult to rust.

  Further, the present invention can be applied not only to a pallet circulation type parking apparatus as in Patent Document 1, but also to other parking apparatuses having the pallet 1. For example, you may apply this invention also to the parking apparatus which moves the pallet 1 between each parking shelf arrange | positioned in the up-and-down several steps | paragraphs, and a warehouse position.
