Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a parking lot for large vehicles that efficiently parks large vehicles such as large trucks and large buses.

[Prior Art] Conventionally, in parking lots where large numbers of heavy and long large vehicles are parked, a flat parking system has been adopted in which the vehicles are parked one after another horizontally on a flat surface. On the other hand, in parking lots for ordinary passengers who are not very heavy and short in length, the sky parking system using rotating lifts and the parking building system using multi-story buildings are generally used. has been adopted.

[Problem to be solved by the invention] When a large vehicle is parked in a conventional parking lot that uses a surface parking system, the space required for the vehicle to run on its own (access space) is minimized. However, due to the large projected area of large vehicles, there is a limit to the number of parking spaces.

In recent years, the price of land in urban areas has continued to rise significantly, and it has become extremely difficult to secure enough land to accommodate a large number of large vehicles.
Therefore, parking lots for large vehicles have traditionally been set up in the suburbs, but due to deteriorating traffic conditions in urban areas and various traffic regulations, it has become very difficult to get back and forth between suburban parking lots and the city center. A problem has arisen in that a large amount of time, effort and fuel must be expended. Therefore, by making effective use of land in urban areas,
It is desired to create a parking lot that can accommodate as many large vehicles as possible within a small site.

Therefore, in order to increase the number of parking spaces for large vehicles, consideration was given to adopting the sky parking system and multi-story parking building system, which are used for large-scale parking of general passenger cars. However, large vehicles weigh 5 to 10 times more than ordinary passenger cars, and
Because it is two to four times as long as a normal passenger car,
No matter which method is adopted, the equipment cost per vehicle will be significantly higher. Therefore, it is economically unreasonable and impractical to adopt these methods for parking large vehicles.

In other words, when using the sky parking method, the lift must have an extremely robust structure, and the drive device to drive the lift must also be equipped with a very large drive device, resulting in an enormous equipment cost. Become something. In addition, when adopting a multi-story parking building system, there is a problem in that, because a very large load is applied to some parts, the same foundation and structure as in the case of building a high-rise building is required, making the construction cost very high. Particularly in this method, when a large vehicle is moved to each floor by self-propulsion, a considerably large access space is required, which raises the problem of higher equipment costs per vehicle. Considering the current situation where land costs are enormous, it is not economically advisable to use the sky parking system or the multi-story parking building system for parking lots for large vehicles.

An object of the present invention is to provide a parking lot for large vehicles that adopts a flat parking system in which large vehicles can be stood up vertically and many vehicles can be parked with a small equipment cost.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention, as shown in FIG. The large vehicle 2 is lifted and transported to a predetermined parking area 3, and the large vehicle 2 is suspended in the parking area 3, and the large vehicle 2 is lifted from the parking area 3, and the large vehicle 2 is transported to a predetermined position, and the large vehicle 2 is leveled. crane means 1 for restoring the vehicle to the original state; vehicle holding means provided in each of the parking areas 3 for holding the large vehicle suspended from the crane means 1 in an upright state; and large vehicle 2 in order to change the attitude of large vehicle 2 when returning large vehicle 2 to a horizontal state.
It is composed of a slope 4 to which a slope 4 is attached.

In this specification, the term "upright state" or "upright state" includes not only a vertical state but also a state where the object is tilted at a certain angle.

Furthermore, in the invention, when the large vehicle is turned vertically or returned to a horizontal state using a crane, the large vehicle is moved along a slope to change the attitude of the large vehicle. Therefore, even if the vehicle models are different, all large vehicles can be lifted or suspended without shaking significantly. As a result, the attitude change work of a large vehicle can be performed safely, and the work efficiency is improved, so there is an advantage that the work time can be shortened.

[Operation of the invention] In the present invention, since a large vehicle is parked vertically, the equipment cost per vehicle is minimized, and compared to the case where the vehicle is parked horizontally, the equipment cost per vehicle is minimized.
~5 times more vehicles can be parked. especially,
According to the present invention, since the crane means is used, the vehicle can be transported to a predetermined parking area and the vehicle can be carried out from the parking area in a short time. Also,
Since it is only necessary to provide at least one crane means, there are advantages in that the number of movable devices can be reduced and the occurrence of breakdowns can be kept low, and the construction cost per vehicle can be significantly reduced.

[Examples] Examples of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a schematic perspective view showing an embodiment of a parking lot for large vehicles of the present invention. In the figure, reference numeral 1 denotes crane means for lifting a large vehicle 2 vertically, transporting it to a predetermined parking area 3, and suspending the vehicle 2 in the parking area 3.

In this embodiment, two crane means 1 are provided. Therefore, it is possible to carry in and carry out two vehicles at the same time, thereby shortening the working time, and it is also possible to carry out one vehicle while the other is preparing to carry it in. These crane means 1 include a pair of columnar parts 1a that are movably provided outside the parking area where the parking areas 3 are assembled, and a columnar part 1a that straddles over the parking area.
It is composed of a beam 1b supported by a pair of columnar parts 1a, and a club 1c fixed to the beam 1b so as to be movable in the longitudinal direction.

Wheels (not shown) are respectively attached to the lower ends of the pair of columnar parts 1a in order to move the columnar parts 1a along rails 1d attached to the site. A beam 1b is integrally provided at the upper end portions of the pair of columnar portions 1a, and a long hole 1b1 extending in the longitudinal direction is formed in the beam b. The club 1c has a suspension wire 1c1 attached to the beam 1b.
It is movably mounted on the upper end surface of the beam 1b so that it can be lowered through the elongated hole 1b1. The structure of this crane means 1 is the same as a gantry crane commonly used in shipyards and factories, so a detailed explanation will be omitted.

4 is for lifting the vehicle 2 vertically with the club 1c and returning the vertically suspended vehicle 2 to the horizontal state, so that the vehicle 2 can be smoothly lifted and returned to the horizontal state without shaking. This is the slope used. If the hook 1c2 provided at the tip of the wire 1c1 of the club 1c is hooked onto the hanging wire 2b at the rear of the frame of the vehicle 2, and the vehicle 2 is lifted while moving along the slope 4, the vehicle 2 is lifted up.
can be lifted with almost no shaking. Although not shown, another slope 4 is provided on the other side wall of the vehicle accommodation structure 5, which was constructed to form a plurality of parking areas 3 in a grid pattern on the site (parking area). It is being

Each parking area 3 of the vehicle storage structure 5 is provided with vehicle fixing means 6 for fixing the vehicle 2 vertically suspended by the crane means 1 in a vertically erect state. This vehicle fixing means 6 is
It is provided on at least one wall 5a of the four walls surrounding the parking area 3 (FIG. 2). In this embodiment, the vehicle holding means is composed of a wall portion 5a and a vehicle fixing means 6.

As shown in FIG. 2, this vehicle fixing means 6 is
The vehicle is fixed to the wall 5a by engaging with both ends of the frame 2a extending in the length direction of the vehicle 2 and drawing the frame 2a to the wall 5a. The vehicle fixing means 6 is composed of a steadying hook mechanism 6b provided on the upper side of the wall portion 5a and a stopper mechanism 6a provided on the lower side. The stopper mechanism 6a is
The stopper arm 6a2 is rotatably fixed to a shaft 6a1 fixed to the wall 5a, and a known hydraulic swing mechanism 6a3 rotates the stopper arm 6a2 about the shaft 6a1. The anti-shake hook mechanism 6b includes a hook 6b2 rotatably fixed to a shaft 6b1 fixed to the wall 5a.
and a known hydraulic swing mechanism 6b3 that rotates the hook 6b2 about the shaft 6b1. The frame 2 of the vehicle 2 is attached to the tip of the hook 6b2.
An engaging portion 6b21 that engages with one end of a is provided. Hydraulic pistons 6a31 and 6b31 of hydraulic swing mechanisms 6a3 and 6b3 are respectively fixed to wall portion 5a.

The vehicle 2 to be erected is a generally commercially available vehicle with some modifications.
Generally, commercially available vehicles are not intended to be stood up, so if they are left upright, fuel, various oils, battery electrolytes, etc. will leak. Therefore, improvements have been made to the parts of the vehicle 2 where fluid may leak when the vehicle is standing up.

For example, the fuel tank has been modified so that the fuel supply port is located at the top when the vehicle is in an upright position. Of course, the seal of the plug that seals the fuel supply port may be strengthened. Leakage of engine oil, brake oil, etc. can be easily prevented by strengthening the plugs and seals at various parts. Furthermore, as for the battery, it is sufficient to use a type of battery that does not use an electrolyte that is currently available on the market. It should be noted that commercially available vehicle frames have sufficient mechanical strength as they are, so there is no need for any special modification.

Although the height from the ground to the frame 2a differs depending on the type of vehicle, this point can be easily addressed by appropriately improving the structure of the vehicle fixing means 6.

Next, the operation of the embodiment shown in FIG. 1 will be explained.
When parking the vehicle 2, the vehicle 2 is first driven backwards to the bottom of the slope 4, and the hanging rope 2b is attached to the frame of the vehicle. Then, the hook 1c2 of the rope 1c1 lowered from the club 1c placed above the upper part of the slope 4 is hung on the hanging rope 2b, and the rope 1c1 is wound up. As a result, the vehicle 2 is gradually raised vertically along the surface of the slope 4. By using the slope 4 in this manner, the vehicle can be easily stood up.

After lifting the vehicle 2 to the highest position, the columnar part 1a of the crane means 1 and the club 1c1 are appropriately moved to transport the vehicle to the top of the desired parking area 3.
After the shaking of the vehicle 2 has stopped to some extent, the rope 1c1 is lowered and the vehicle is inserted into the parking area 3 surrounded by four walls. At this time, the bottom surface portion of the vehicle 2 where the frame is exposed is made to face the wall portion 5a to which the vehicle fixing means 6 described above is attached. If the vehicle 2 is inserted into the parking area 3 so that the wheels of the vehicle 2 come into contact with the wall 5a, the vehicle fixing means 6 can be easily activated to position and fix the vehicle to the wall 5a.

After the vehicle 2 is fixed to the wall portion 5a by the vehicle fixing means 6, the rope 1c1 is removed from the hanging rope 2b. This work should be carried out by a worker as appropriate.
If a self-supporting pipe means is used instead of the hanging rope 2b, the hook 1c2 of the rope 1c1 can be removed without the help of an operator.

When transporting the vehicle 2, the above operation may be performed in reverse. When using the hanging rope 2b, a worker attaches the hook 1c2 to the rope 2b.

In this embodiment, a movable stopper mechanism 6a is provided in order to accommodate the difference in frame length due to different vehicle types, but from the viewpoint of the function of the stopper mechanism to support the vehicle, the arm 6a2 can be moved to the wall. It may be fixed so as to stand approximately perpendicular to the surface of 5a.

In this embodiment, two crane means 1 (gantry cranes) are used, but it is obvious that the present invention can be carried out with one crane means.

In the above embodiment, since the vehicle is lifted as it is, there is a problem in that the vehicle shakes and the workability is poor. Therefore, as shown in FIG. 3, a vehicle fixing frame 7 for preventing shaking may be provided integrally with the club 1c. The fixed frame 7 is composed of a pair of side walls 7a and 7a fixed to the side wall portion of the club 1c and arranged on both sides of the beam 1b, and a connecting wall 7b connecting these side walls 7a and 7a. When the lower ends of the side wall 7a and the connecting wall 7b are positioned directly above the slope 4, they extend to a position where they face each other with a gap that does not hinder movement between them and the upper end of the slope 4. ing. Yotsute slope 4
The vehicle that has been lifted along slope 4
The vehicle fixing frame 7 can be smoothly lifted onto the connecting wall 7b of the vehicle fixing frame 7. Furthermore, since the vehicle can be restrained by the side walls 7a and 7a and the connecting wall 7b, it is possible to prevent the suspended vehicle from shaking when the crane means 7 moves. The fixed frame 7 also functions as a guide means that allows the axle 2 to be smoothly suspended along the wall 5a of the parking area 3 when the vehicle 2 enters the parking area 3. In order to more reliably prevent the vehicle 2 from shaking, a fixing means having the same structure as the vehicle fixing means 6 provided on the wall portion 5a may be provided on the connecting wall 7b of the fixing frame 7.

According to each of the above embodiments, when large vehicles are parked, it is possible to park about 4 to 5 times as many vehicles on the same lot as compared to the conventional case where vehicles are parked horizontally. , equipment costs per vehicle can be reduced to 1/4 of the conventional cost compared to parking using sky parking or multi-level parking.
It can be:

In each of the above embodiments, a gantry crane type crane is used as the crane means, but it will be obvious to those skilled in the art that various other types of cranes, such as an overhead crane, can be used.

Furthermore, in each of the above embodiments, the vehicle is stood up with the front part of the heavy vehicle facing down in order to locate the center of gravity further down, but the vehicle may also be stood up with the leading part facing up. Of course.

Further, in each of the embodiments described above, the vehicle is stood up in a substantially vertical state, but it goes without saying that the vehicle may be stood up at an angle. In this case, the wall portion 5a of the vehicle accommodation structure 5 may be inclined.

[Effects of the Invention] According to the present invention, since a large vehicle is parked vertically, the equipment cost per vehicle is minimized, and compared to the case where the vehicle is parked horizontally, it is possible to park a large vehicle vertically. You can park 5 times as many vehicles.
In particular, according to the present invention, since the crane means is used, the vehicle can be transported to a predetermined parking area and removed from the parking area in a short time. Also,
Since it is only necessary to provide at least one crane means, there are advantages in that the number of movable devices can be reduced and the occurrence of breakdowns can be kept low, and the construction cost per vehicle can be significantly reduced. Furthermore, in the invention, when a large vehicle is turned vertically or returned to a horizontal state using a crane, the posture of the large vehicle is changed by moving the large vehicle along a slope. It is possible to lift or suspend a large vehicle without shaking it significantly. Therefore, the attitude change work of a large vehicle can be carried out safely, and the work efficiency is improved, so there is an advantage that the work time can be shortened.
