Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a tunnel parking system that uses a tunnel formed laterally underground as a parking space.

(Prior Art) Parking devices that use the basement of a building as a parking space are generally known. For example, JP-A-60-
Publication No. 73972 discloses that an upper and a lower parking area is formed in the basement of a building in which pallets for carrying vehicles can be horizontally transferred, and the pallets are circulated between both parking areas. Lateral transport at the end of the road,
A vehicle is described that is provided with a lifting means for lifting and lowering a vehicle on a pallet between an entrance on the ground and both parking areas.

In addition, vehicles can be parked on a dolly as a parking device built on the ground.
It is known that parking sections are provided on both sides of the transport lane for vehicles to be transported on a dolly, and vehicles are transferred between the above-mentioned dolly and the parking section (for example, Utility Model Application No. 59-1
(See Publication No. 85366). That is, in this device, the dolly is provided with a movable platform equipped with a comb-shaped fork for supporting the tires of the vehicle, while a comb-shaped receiver for vertically passing the fork through each parking section is provided. The movable platform on the dolly is moved above the parking section, and the movable platform and the parking section are moved up and down relative to each other. Vehicles are transferred at the station.

(Problems to be Solved by the Invention) However, conventional parking devices usually have only one entrance and exit, and even when 211 entrances are provided, they are installed in one building. Therefore, for example, if a parking device is installed at one end of a long shopping street, even if you use the parking device to go shopping, etc.
I need to return to the place of death. Moreover, since those shopping and those returning to the parking area walk in opposite directions, the flow of people in the shopping district becomes poor, leading to congestion.

Furthermore, in the case of conventional parking devices, a large number of vehicles can be accommodated in one location, but it is difficult to secure a large parking space in places such as shopping districts, and therefore the number of vehicles that can be accommodated is limited. It is normal to come.

Each guide rail 48 extends vertically between the parking area IIA and the first vehicle transport lane 8, and engages rollers 49 provided on each parking platform 46, 47 to guide the elevation and descent of each parking platform. It looks like this. The driving means is for each parking platform 46.4
The parking platform 46 is composed of a chain suspended from sprockets arranged above and below, and a motor that rotationally drives the sprockets.
．． 47 are raised and lowered at the same height.

The rune changing means 21 is shown in FIGS. 12 and 13.

This rune change means 21 is a movable rail that supports wheels 32 at 4M1 locations in the front, rear, left, and right of the dolly 18 and moves up and down between the three vehicle transport lanes 8 and 9 and the dolly exclusive lane 19. It consists of four lifting means 51 with 50.

First, the above three lanes 8. 9. 19 transport rails 8
a, 9a, and 19a are partially open and discontinuous so that the movable rail 50 can pass vertically, as shown in FIG. 12 for the first vehicle transport lane 8 in the upper stage. The four movable rail lifting means 51 are as follows:
A plurality of movable rails 5 each having the same configuration.
0, an elevating device consisting of upper and lower sprockets 52, 53 and a chain 54 for elevating the movable rail 50, and a guide rail 55 for guiding the movable rail 50 as it moves up and down.

Specifically, the upper and lower sprockets 52 and 53 are attached to the support frame 14 with horizontal axes in the longitudinal direction of the lane at the position of the first vehicle transfer lane 8 in the upper stage and the position of the dolly-only lane 19 in the lowermost stage, respectively. It is rotatably supported. A chain 54 is suspended around both sprockets 52 and 53, and is driven by a motor (not shown). Further, the guide rail 55 has a U-shaped cross section, and extends vertically between the three lanes along the chain 54 inside the chain 54 (on the lane center side). Each movable rail 50 is then connected to the chain 54 via a bracket 56,
A guide roller 57 movably engaged with the guide rail 55 is supported by this bracket 56.

In this case, the movable rail 50 is usually the transport rail 8
A, 9a, and 19a are positioned at the same height, thereby ensuring the running of the dolly 18.

When changing lanes, the dolly 18 is stopped on the four movable rails 50, and these movable rails 50
By raising and lowering the dolly 18, the dolly 18 is moved between lanes.

The second lane changing means 22 includes the second lane changing means 2
The structure is the same as 1. The difference is that the first lane changing means 21 connects both ends of each of the three lanes, whereas the second lane changing means 22 connects the three lanes near the connecting shaft 7. Therefore, a detailed explanation of the structure of the second lane changing means 22 will be omitted.

Next, the entry and exit of the vehicle W in the tunnel parking system will be described.

A vehicle W carried into the tunnel 6 is guided from the roadway 2 on the ground to one of a plurality of entrances 1 opening into the median strip 3 via a branch road 4. The elevating means 15 raises the elevating platform 25.26 to the entrance/exit 1, receives the vehicle W on the elevating platform 25.26, and lifts the elevating platform 25. 26 is lowered from the connecting shaft 7 to the first vehicle transport lane 8 or the second vehicle transport lane 9. In this case, if the owner of the vehicle W has a preference regarding the exit location in advance, information regarding the desired entrance/exit 1 is obtained.

■ Transfer to a dolly In the first vehicle transfer lane 8 or the second vehicle transfer lane 9, notification of the arrival of the vehicle W from the entry/exit port 1 is received, or in advance, the connecting shaft where the vehicle W is entered is transferred. An empty dolly 18 is moved and stopped directly below the dolly 7. and,
The elevating platform 25, 26 is lowered to below the vehicle support base 31 by passing its forks 25a, 26a between the forks 31a of the vehicle support base 31 of the dolly 18. By this passage, the forks 2 of the lifting platform 25, 26
The vehicle W is transferred from 5a and 26a to the fork 31a of the vehicle support stand 31.

In principle, the dolly 18 of the section where the entrance/exit 1 is provided is in charge of warehousing through the entrance/exit 1. At that time, when moving the empty dolly 18 directly below the entrance/exit 1, if there is another dolly 18 on the way that is transferring the vehicle W to the parking section, Since the vehicle transport lanes 8 and 9 are one-way traffic, the empty dolly 18 cannot be moved until the above-mentioned transfer work is completed. Therefore, in this case, the empty dolly 18 in another section uses the second lane changing means 21 and the second lane changing means 22 to bypass the dolly 18 undergoing the transfer operation. He will move directly under the warehouse entrance 1 and will be in charge of warehousing.

If the above-mentioned dolly 18 is before the transfer operation, the other dolly 18 can be circulated using the lane change means 21 and 22 without being used for the transfer operation. - The vehicle is evacuated to the dedicated lane 19, and priority is given to running the empty dolly 18 to the entrance/exit 1.

■ Transport to parking area When the vehicle W is received by the dolly 18 in the second vehicle transfer lane 8, the dolly 18 transfers the vehicle W to the empty parking area 13A in the lower parking area 13. transport.

At that time, if information about the entrance/exit 1 to be exited is obtained in advance, it is possible to find an empty parking area other than the above-mentioned parking area, that is, another parking area close to the entrance/exit 1 to be exited. The vehicle W will be transported to the parking section.

■Accommodating vehicles in the parking section The dolly 18 stops at the parking section 13A where the vehicle is scheduled to be parked. When parking, the dolly 18 moves the vehicle support base 31 from above the vehicle platform 33 to the parking section 13A with the vehicle W placed thereon. At that time, since the parking platform 40 of the lower parking area 12 is located at a lower position than the vehicle support platform 31 of the dolly 18,
The vehicle support stand 31 and the parking stand 40 do not interfere. and,
The parking platform 40 is raised to a higher position than the vehicle support platform 31 by the operation of the air cylinder device 41. At that time, the fork 44 of the parking platform 40 is connected to the fork 31 of the vehicle support platform 31.
The vehicle W is transferred from the vehicle support stand 31 to the parking stand 41 by passing through the area b. Thereafter, the vehicle support platform 31 returns to the platform 33 of the dolly 18, and the parking platform 40 is lowered to a predetermined parking height.

Note that the vehicle W is moved from the lifting means 15 to the first vehicle transport lane 8.
When the vehicle W is received by the dolly 18 in the second vehicle transport lane 9 and parked in the middle parking area 12, the vehicle W is transported and accommodated in the same manner as in the case where the vehicle W is received by the dolly 18 in the second vehicle transport lane 9 described above. It will be done.

Next, the vehicle W is moved from the lifting means 15 to the first vehicle transport lane 8.
A case where the vehicle is received by the dolly 18 and parked in the upper parking area 11 will be explained.

In this case, the planned parking section 1 in the upper parking area 11
In 1A, the parking stalls 46 and 47 are lowered in advance to a lower position than the dolly 18. In that state, Dolly-1
8 is driven to the parking lot 46 of the above-scheduled parking section 11A.
．． Stop on top of 47.

Thereafter, the parking platform 46, 47 rises and receives the vehicle W from the fork 31a of the dolly 18 with the comb-like forks 46a and 47a.

- Departing - ■ Moving the dolly to the parking section The empty dolly 18 is moved to the parking section of the parking area where the vehicle W scheduled to leave is accommodated. In this case, vehicle W
When the vehicle W is parked in the parking section of the parking area near the entrance 1 where the owner is waiting, the dolly 18 in charge of entering and exiting the parking area goes to retrieve the vehicle W. If this is not the case, either the dolly 9-18 in charge of the parking area where the vehicle W is parked or the dolly 18 in charge of the entrance/exit 1 where the owner is waiting will pick up the vehicle W. .

Even when moving an empty dolly 18 to the parking section, there is another dolly 18 on the way that is transferring a vehicle W to and from the parking section, making it impossible to move the dolly 18. In this case, as in the case of single-person warehouse 10, the first lane changing means 21 and the second lane changing means 22 are used to bypass the dolly 18 during the transfer operation and carry out the loading/unloading process. Mouth 1
It will be moved directly below.

If the other dolly 18 is before the transfer operation, the other dolly 18 is moved to the lane changing means 21. 22 can be used for evacuation, and priority can be given to traveling the empty dolly 18 to the parking area.

(2) Retrieval of a vehicle from the parking section This retrieval is performed in the reverse manner of storing the vehicle in the parking section (2) in the above-mentioned warehousing. That is, in the case of taking out the vehicle W from the middle and lower parking areas 12.13, the parking platform 40 of the parking area 12.13 is placed in advance by the dolly 1.
The vehicle support base 31 of the dolly 18 is moved to a higher position than the vehicle support base 31 of the dolly 18 from above the vehicle base 33 in this state. Then, the parking platform 40 is lowered and the vehicle support platform 31 is lowered from the fork 44 of the parking platform 40.
Move the vehicle W to the fork 31b. After that, the vehicle support platform 31 is returned to the platform 33 of the dolly 18, and the parking platform 4
0 to a predetermined parking height.

On the other hand, in the case of taking out a vehicle from the upper parking area 11, the parking platform 46.47 of the upper parking area 11 is lowered, and the vehicle W is moved from the forks 46g and 47a of the parking platform 46.47 to the fork 31a of the dolly 18. will be transferred.

■Transportation below the entrance/exit The vehicle W received from the parking section is transported under the entrance/exit 1 using a dolly 18. In transporting this vehicle W,
If there is another dolly 18 on the way that is transferring a vehicle W to or from the parking section 13A, the lane can be changed using the second lane changing means 22, so that the other dolly 18 can be transferred to or from the parking section 13A. The vehicle W can be transported by bypassing the dolly 18.

At this time, if the second lane changing means 22 is located near the connecting shaft 7, the dolly 18 can quickly travel to the entrance/exit. Also, in this case, the other dolly 1
8 is before the transfer operation, the other dollies 18 can be evacuated using the lane change means 21, 22, and priority can be given to the running of the dollies 18 to the entrance/exit.

(2) Transferring to the lifting means 15 The lifting tables 25 and 26 are lowered in advance to a lower position than the dolly 18, and then the dolly 9-18 is stopped. Then, when the lifting platform 25.26 is raised, the forks 25a and 26a of the lifting platform 25.26 move to the dolly 18.
By passing between the forks 31a of the vehicle support stand 31 and rising, the vehicle W is taken up from the vehicle support stand 31 of the dolly 18 to the lifting platform 25, 26.

■ The elevator platform 25, 26 that received the vehicle W to be carried out of the tunnel (on the ground) is raised directly to the entry/exit entrance 1, and the vehicle W is handed over to its owner. Therefore, the vehicle W is driven by the owner to be taken out from the entrance 1 to the roadway 2 via the branch road 4.

Next, FIG. 14 shows another embodiment of the arrangement of vehicle transport lanes and parking areas.

That is, in this example, the three vehicle transport lanes 81, 82, and 83, upper, middle, and lower, are arranged at the center of the tunnel cross section,
Dolly-only lane 84 below lower vehicle transport lane 83
In addition, each vehicle transport lane 81, 82.8
Parking areas 85, 85, 86, 86 on both sides of 3 respectively.
, 87.87 are arranged. In addition, there are walking paths 88 for inspection and maintenance outside the parking areas on both sides. 8
8 is provided.

In this example, for example, both upper and middle vehicle transport lanes 8
1.82 will be one-way traffic in the same direction, and the lower vehicle transport lane 83 and the dolly lane 84 will be used as the vehicle transport lane 8.
1.82 can be one-way traffic in the opposite direction. In other words, in shopping districts, etc., the flow of customers tends to be concentrated in one direction, and it is difficult for vehicles W to enter the tunnel from a position corresponding to one end of the shopping district and exit from a position corresponding to the other end. There will be more. In that case, by matching the transport direction of both the upper and middle vehicle transport lanes 81, 82 with the flow direction of customers, it is possible to smoothly take out the vehicle W.

In each of the above embodiments, the vehicle transport direction is one-way, but it may be two-way.

Further, the evacuation area may not be dedicated to the dolly, but may be an area where the dolly and the vehicle can be evacuated together.

Further, in the above embodiment, the vehicle transport lanes are arranged vertically, but they may be arranged on the left and right, and the left and right vehicle transport lanes are connected by a lane changing means.

Further, although the connecting shaft in the above embodiment is used for both warehousing and unloading, a connecting shaft exclusively for warehousing and a connecting shaft only for warehousing may be provided.
