Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle-mounted pallet in a mechanical parking facility, and more particularly to a pallet reinforcement measure.

[0002]

2. Description of the Related Art Conventionally, as a vehicle mounting pallet for mounting a vehicle in a mechanical parking facility and storing it in a parking portion, a metal plate as disclosed in, for example, JP-A-51-147868 is used. There is one that is folded and configured. The sectional shape is as shown in FIG. That is, the pallet a is provided with a pair of wheel mounting plate portions d, d on which the wheels c, c, ... Of the vehicle b are mounted in the vehicle loading state.
d is arranged at intervals in a direction e orthogonal to the vehicle entry direction. A center rising plate part f is provided between the two wheel mounting plate parts d and d so as to extend in the vehicle entry direction. The center rising plate part f is formed between the two wheel mounting plate parts d and d. It is composed of rising walls h, h rising upward from the respective inner ends, and a horizontal wall i connecting the rising walls h, h to the compatible rising walls. Also,
Side stand-up plate parts j, j are provided at the outer end portions of each of the wheel mounting plate parts d, d so as to stand up, and the wheel mounting plate part d, the center stand-up plate part f and the side parts are formed. Rising plate part j
Both extend parallel to the vehicle loading direction, and the wheels c, c, ... Are mounted on both wheel mounting plate portions d, d in a state where the vehicle b is mounted on the pallet a.

However, as shown in FIG. 9, the pallet a formed by bending such a metal plate has a load applied to both wheel mounting plate portions d, d when the vehicle b is in the vehicle. Both of the rising walls of the central rising plate portion f are pulled outward by h and h, so that the central rising plate portion f is expanded, and as a result, both sides of the pallet a are bent upward to be curved. There is a problem that the wheel mounting plate portions d, d are inclined in an inverted “C” shape and the cross-sectional shape is broken, so that the strength of the pallet a is reduced, and the bending portion when the pallet a moves moves interferes with other portions. There is.

Therefore, for example, as disclosed in Japanese Utility Model Laid-Open No. 2-36567, reinforcing members (horizontal bones) extending in a direction orthogonal to the vehicle loading direction are arranged at four positions on the back surface of the pallet in the vehicle loading and unloading direction. There has been proposed a pallet that is reinforced with a pallet so that the pallet does not bend sufficiently against the load of a vehicle that has entered the pallet.

[0005]

However, in the pallet of the above-mentioned proposed example, since the reinforcing member extends in the entire direction orthogonal to the vehicle loading direction of the pallet, that is, from one side rising plate portion to the one next to it. Since the wheel mounting plate section, the center rising plate section, and the other wheel mounting plate section extend from one end to the other side rising plate section, the reinforcing member is long and the weight of the entire pallet increases. Moreover, since the reinforcing member is made of the square pipe material, the weight is further added. Therefore, the material cost is increased accordingly, and in a mechanical parking facility that requires a large number of pallets, the total weight added per pallet becomes enormous, and a large power source is required to operate the parking device. I need.

Also, since the reinforcing member is a square pipe material,
If the amount of downward protrusion of the reinforcing member from the bottom surface of the pallet is large and the pallets are arranged vertically such as in vertical circulation parking equipment, the space between the pallets must be adjusted so that adjacent pallets above and below do not interfere with each other. Must be secured sufficiently, and the number of storages will decrease accordingly.

In order to increase the strength and rigidity of the pallet without providing the reinforcing member, it is necessary to increase the plate thickness of the metal plate forming the pallet, resulting in a significant increase in weight and a rise in material cost. In addition, the power source for operating the parking device is increased in size.

The present invention has been made in view of the above points, and an object thereof is to analyze a bending phenomenon of a pallet due to a load of a vehicle and reinforce only a portion causing the bending with a plate material. Therefore, it is intended to eliminate a significant increase in the weight of the pallet and to avoid a high material cost and a large power source for operating the parking device. Furthermore,
There is also a case in which the amount of protrusion of the reinforcing member to the lower side of the pallet is reduced to narrow the space between vertically adjacent pallets, thereby increasing the number of stored pallets.

[0009]

In order to achieve the above-mentioned object, the present invention is constructed by bending a metal plate,
The following solution measures were taken for a vehicle-mounted pallet in a mechanical parking facility in which a vehicle is mounted and stored in a parking section.

That is, the first solution means of the present invention is, as the pallet, between a pair of wheel mounting plate portions on which the wheels of the vehicle are mounted in a state where the vehicle is loaded, and between the both wheel mounting plate portions. The center rising plate portion is provided so as to extend in the vehicle entry direction. In this case, the two wheel mounting plate portions are arranged so as to extend in the vehicle entry direction and be spaced apart in the direction orthogonal to the vehicle entry direction. The central rising plate portion is composed of a rising wall that rises upward from the inner end of each of the two wheel mounting plate portions, and a horizontal wall that connects the compatibility rising walls. Then, both ends of a reinforcing plate extending in a direction orthogonal to the vehicle entry direction are fixed to the inner ends of the two wheel mounting plate parts, and the inner ends of the two wheel mounting plate parts are fixed by the reinforcing plates. The feature is that they are connected on the back side of the pallet.

According to a second solving means of the present invention, in the first solving means, the reinforcing plate has a protruding portion protruding upward. The protruding portion is characterized in that the protruding portion is brought close to or in contact with the rear surface of the horizontal wall of the central rising plate portion.

According to a third solving means of the present invention, in the first solving means, the reinforcing plate has a protruding portion protruding upward. The protrusion is fixed to the back surface of the horizontal wall of the central rising plate.

A fourth solution means of the present invention is characterized in that, in any one of the solution means of the first to third solutions, a plurality of reinforcing plates are arranged at a predetermined interval in the vehicle entry direction. .

[0014]

With the above structure, in the first means for solving the problems of the present invention, when the vehicle is loaded on the pallet, the load is transmitted to the pair of wheel mounting plate portions through the wheels, and the central rising plate portion located between them. External force is applied to the rising wall in the direction to pull it outward. However, the two wheel mounting plate parts can sufficiently resist the external force by the reinforcing plates connecting the two wheel mounting plate parts, and the central rising plate part does not expand. Therefore, both sides of the pallet do not warp upwards, and the pallet remains horizontal,
Therefore, the two wheel mounting plate parts are horizontal without being inclined in an inverted “C” shape, the cross-sectional shape is not collapsed and the strength of the pallet is maintained, and the bent part is not changed by the movement of the pallet. There is no interference with the part.

At this time, since both ends of the reinforcing plate are fixed to the inner end portions of both wheel mounting plate portions and the inner end portions are connected to the back side of the pallet, the horizontal of the central rising plate portion is fixed. It only needs to be a little longer than the width of the wall, and because it is a short reinforcing plate and is a plate material, the weight of the pallet is significantly larger than that when the reinforcing member is installed over the entire direction orthogonal to the vehicle entry direction. No increase in material cost. Further, even when a large number of vehicles are stored, the total weight of the pallet does not increase so much, and the power source for operating the parking device can be small. Furthermore, since the reinforcing plate is thinner than the reinforcing member of the square pipe material, the protruding amount to the lower side of the pallet is small, and even if the interval between the vertically adjacent pallets is narrowed, they do not interfere with each other. The number of stores increases.

According to the second solution of the present invention, when the load of the vehicle is applied to both wheel mounting plate portions, the protruding portion protruding upward of the reinforcing plate supports the horizontal wall of the central rising plate portion from the back side. The projecting portion also shares the load, the load of the vehicle is dispersed, and the load on the wheel mounting plate portions is reduced. Therefore, the external force of pulling the central rising plate portion outward with respect to the rising wall is reduced, and the connecting portion between the reinforcing plate and both wheel mounting plate portions is strengthened.

In the third means for solving the problems of the present invention, the reinforcing plate is fixed to the horizontal wall as well, and the number of fixing points is three, which is advantageous in that the mounting strength is improved in addition to the effect of the second means for solving. is there.

According to the fourth solution of the present invention, the load of the vehicle is distributed to the plurality of reinforcing plates, and the external force of the central rising plate portion against the rising wall is further reduced.
The connecting portion between the reinforcing plate and the two wheel mounting plate portions becomes stronger.
