JP2561491B2 - Multi-level parking system - Google Patents

Description

Description: TECHNICAL FIELD The present invention relates to a multi-story parking lot that does not require a conveyor, a horizontal transfer device such as a roller, and a transfer auxiliary tool such as a pallet.

(B) Conventional technology Many proposals have been made for a three-dimensional parking lot for automobiles.
However, few have been put to practical use.

Many of them have a complicated structure, and the operations of warehousing and warehousing are also complicated.

A gondola-type rotary parking system has been put to practical use. This is a gondola that can be equipped with a car and is installed at equal intervals in a chain that makes a vertical orbit. At the lowest point, cars can be put in and taken out.

This requires the use of an extremely up-and-down chain, as all the cars weigh in the chain.

Furthermore, in order to move in and out of one car, all cars must be moved.

The device is extremely large. There are too many moving parts, which increases construction costs.

As a means for moving an automobile placed in a parking lot, there is, for example, a method in which a large number of parallel rollers are arranged in a vertical direction, the rollers are rotated, and tires are placed on the rollers to move them. For example, Japanese Examined Patent Publication No. 50-7345.

Further, there is also a vehicle in which the car is placed on the pallet and the side brakes are pulled so that the car does not fall from the pallet so that the pallet can be conveyed for each pallet.
For flat parking lots, there is Japanese Examined Japanese Patent Publication 55-10747.

In a multi-storey car park, it is extremely common to mount a car on a pallet and move it up and down, left and right.

For example, JP-A-61-28677, JP-A-61-47355 and JP-A-61-203960 are available.

JP-A-61-28677 raises and lowers a car placed on a pallet by using a panda graph. Further, a large number of rollers having axes in the front-rear direction and the left-right direction are provided upward, the pallet is guided onto the roller, and the pallet is moved left and right by the rotational driving of the roller.

This requires a large number of rollers to support the pallet from below and a large number of roller drives.

Exquisite. However, it is a very complicated and expensive device.

This is because the pallet tries to move in the four directions of front, rear, left and right in the horizontal plane.

No. 61-47355, a car mounted on a pallet is moved forward and backward by a conveyor belt. Take the nail out of the conveyor, hook it on the pallet, and pull or push the pallet to move it back and forth.

In the actual Kaisho 61-203960, a car placed on a pallet is moved back and forth by a conveyor belt. This is to carry the pallet directly on the conveyor belt.

The car left in the parking lot is stopped by pulling the side brakes, so it cannot move by itself. For this reason, they will be carried on a pallet.

 The method using a pallet is extremely troublesome.

Since it is a board on which a car is placed, it is a wide board of about 2m x 5m. It is difficult to leave many pallets in and out.

Therefore, an empty pallet will be placed in an empty parking booth. If the number of parking booths is N, the number of pallets is also N
I need one.

When a vehicle desiring to enter arrives, an empty pallet must be brought from an empty parking booth.

On the contrary, after leaving the warehouse, the empty pallet must be carried to the empty parking booth.

That is, the elevator has to make two round trips between the parking booth and the entry / exit position each time it enters or exits.

This is a time consuming operation. Annoying and undesirable. Elevator utilization efficiency is reduced, and the number of parking booths that can be processed by one elevator is limited.

In order to solve this difficulty, Jitsukai Sho 61-203960 is provided with an empty pallet carrier and an empty pallet yard separately.

This requires a large space due to the empty pallet yard. Moreover, two types of transport devices are required.

It is a large and complex device. The required land area is also large.

Japanese Patent Publication Sho 57-28782 is proposed as a three-dimensional warehouse instead of a parking lot.

It has a long floor with a slight slope and two elevators in front of and behind the floor. Set up a stopper on the front floor.

When the car lifted by the later elevator is taken out to the floor,
Drive due to own weight. The side brakes are not pulled.

Cars are carried one after another.

The first unit slowly moves forward on the floor and stops at the front stop.

Similarly, the second unit slowly moves forward on the floor and stops at the first bumper.

The same applies hereinafter. Multiple cars can be placed on a long sloping floor.

When removing from the warehouse, remove the stopper and carry it out one by one by the elevator in front.

Since this is a warehouse, there is no need to leave any car at any time. Only first-in, first-out is possible.

However, Japanese Patent Publication No. 57 in that it is driven by its own weight
-28782 is probably the closest thing to the present invention.

 However, the movement is unidirectional and the sloping floor is immobile.

(C) Purpose It is an object of the present invention to provide a simple multi-storey car park device having a structure that allows a vehicle to be quickly put in and an arbitrary vehicle can be quickly put out without using a conveyance aid such as a pallet or a conveyor, or a conveyance means. Is.

(D) Structure The device of the present invention enables the elevator and the floor plate of each parking booth to be inclined in the front-rear direction.

The elevator is lifted to the position of the parking booth, and both floor plates are tilted in the same direction, so that an unmanned car with no side brakes is moved between the elevator and the parking booth by its own weight.

 This is a feature.

 This will be described with reference to the drawings.

1 to 4 are partially cutaway side views showing a procedure for loading and unloading the multi-story parking apparatus of the present invention.

This shows the fifth floor with eight parking booths, but the number of floors N and the number of parking booths are arbitrary.

Since it is used from the 2nd floor, if the number of floors is N, 2 (N-1)
Become a room. If there is a parking booth on only one side of the elevator, it will be the (N-1) room.

A control device can be installed on the part of the first floor opposite the approach road.

The multi-storey car park device of the present invention includes a parking building 1 on an appropriate number of floors,
It is composed of an elevator 2 which can be moved up and down.

The elevator 2 is a lifting device 3 provided above the top floor.
It can be lifted up and down.

The suspension part 5 of the elevator 2 and the lifting device 3 are connected by a suspension wire 4.

The elevator 2 is composed of a frame body such as an elevator upper frame 6, an elevator vertical frame 7, and an elevator lower frame 8. This is a frame body that is lifted and lowered by the suspension unit 5. This frame does not tilt.

Further, the elevator 2 has as a floor board a carrier 9 for carrying and carrying an unmanned automobile.

The carrier 9 is not fixed to the frame of the elevator 2. It can be tilted back and forth.

A swing frame 10 is provided separately from the frame of the elevator, and the carrier 9 is fixed to this. The swing frame 10 can tilt with respect to the elevator frame.

The parking building 1 has a vertical skeleton such as vertical frames 11 set up at the four corners, a sub-frame 12 on the side surfaces close to the four corners, and a guide frame 13 for guiding the elevator 2.

In the horizontal direction, there is a horizontal frame 14 connecting them. The lowermost base frame 15 of the horizontal frame is embedded in the ground.

Although the horizontal frame 14 is shown for each floor of the parking booth, it may be different. Actually, the cycle of the horizontal frame does not have to correspond to the rank.

Further, wall surfaces or mesh plates may be provided between the vertical and horizontal frames. For simplification, the skeleton part is not shown.

The guide frame 13 guides the elevator 2 correctly up and down. The frame of the elevator itself is prevented from tilting by the action of the guide frame 13.

In the elevator 2, only the rocking frame 10 and the carrier 9 tilt.
It leans back and forth instead of in one direction.

Therefore, the elevator lower frame 8 has a rear pivot 20 and a front pivot 21.
Is installed horizontally.

On the lower surface of the carrier 9, bearings 23, 24 having a downward semicircular cross section are provided.
Therefore, they can be fitted to the rear pivot shaft 20 and the front pivot shaft 21, respectively.
When the two are fitted together, the carrier 9 is horizontal.

Further, the carrier base 9 is provided with a rear stopper mechanism 25 and a front stopper mechanism 26 that prevent the automobile from moving by hitting the wheels 60 of the automobile 50. Each of the stopper pieces 28 is the carrier 9
It can be projected to the upper surface of the or can be retracted downward.

Further, in order to stably fix the elevator 2, fixing mechanisms 29 are provided on the four sides of the elevator vertical frame 7. Correspondingly, fixing brackets 31 are attached to the guide frame 13 on each of the four sides of each floor.

The elevator 2 is suspended from the lifting device 3 by a suspension wire 4. However, positioning by winding the wire is inaccurate.

Since the present invention moves the vehicle by the inclination of the floor plate,
The height of the elevator 2 must be set strictly.

Furthermore, since a 1.5 ton vehicle suddenly gets on and off, the suspension wire 4 is elastically deformed and its position is apt to be misaligned.

In order to prevent this, the elevator may be fixed at the four corners by the fixing bracket 31 having the chevron teeth and the fixing mechanism 29.

 FIG. 5 shows an enlarged view of the fixing bracket 31 and the fixing mechanism 29.

A movable metal fitting 62 having chevron-shaped teeth is also provided on the elevator side.

The movable fitting 62 can be moved back and forth in the horizontal direction by the hydraulic cylinder 61.

The guide plate 63 is fixed to the elevator frame. The movable fitting 62 is guided by the guide plate 63.

A hydraulic pressure source 64 is provided to apply hydraulic pressure to the hydraulic cylinder 61.
The piston 67 can be moved back and forth by switching the switching valves 65 and 66.

This is simultaneously performed by the four fixing mechanisms 29 provided at the four corners.

When the movable fitting 62 is separated from the fixed fitting 31, the elevator 2 can move up and down.

When the movable bracket 62 is strongly pressed against the fixed bracket 31,
Elevator 2 cannot move.

Moreover, since the metal fittings having the chevron-shaped teeth are engaged with each other, the stop height of the elevator can be specified precisely.

Behind and in front of the elevator top frame are hoisting devices 33, 34,
The swing frame 10 can be slightly lifted at the rear and the front.

When the rear of the swing frame 10 is lifted by the rear hoisting device 33, the carrier 9 is tilted forward with the front shaft 21 and the bearing 24 as fulcrums.

When the front is lifted by the front hoisting device 34, the rear pivot 20,
With the bearing 23 as a fulcrum, the carrier 9 tilts backward.

One of the spaces on the first floor serves as a car entry path 35. The center of the first floor is the boarding / alighting position 36 where the passenger can get on and off the elevator 2.

 Next, the structure of the parking booth 40 will be described.

 It comprises a parking pedestal 41 on which the car is placed.

The parking base 41 has an inner end or an outer end supported by a support shaft, and the other end can be moved up and down. For this reason, parking 41
Can lean inward or outward.

 The one that leans outward is the stable position.

It never stops in the horizontal direction. It is different from the conventional pallet, and also different from the conveyor that moves the pallet. This is because it does not move horizontally and does not take a horizontal position.

In this example, the inner end of the parking pedestal 41 is rotatably supported by the support shaft 42.

A platform seat 43 fixed to the sub-frame 12 is provided below the outer edge of the parking platform 41. This supports the outer edge of the parking pedestal 41. The state where the parking platform 41 is supported by the platform seat 43 is stable. At this time, the parking pedestal 41 is tilted outward.

 The platform lifting mechanism 44 vertically displaces the outer end of the parking platform 41.

The tail of the platform lifting mechanism 44 is connected to a part of the parking building 1 such as the vertical frame 11 or the vertical wall. The tip of the rod 47 of the platform elevating mechanism 44 that can be moved back and forth is connected to the outer end of the parking platform 41 by a pin 48.

A stopper piece 45 protruding upward is provided at a position near the outer end of the parking stand 41. This is a fixed member that wraps around the tires of an automobile.

The configuration of the device of the present invention is sufficient.
However, for safety, a second stopper can be provided on the parking pedestal 41 as shown in FIG.

The movable stopper mechanism 46 can cause the safety stopper 49 to project above the parking pedestal 41. This can also be retracted.

This prevents the vehicle from moving and falling into the space through which the elevator passes when the parking platform 41 is tilted forward due to a malfunction of the device.

(E) Action In FIG. 1, some cars 51, 52, 53 have already been
However, it is parked in the parking booth 40. This is a state where the parking platform 41 is tilted outward. The pedestal seat 43 supports the parking pedestal 41.

 The tilt angle may be about 1 ° to 5 °.

 The elevator 2 is located at the entry / exit position 36 on the first floor.

A car 50 wishing to park enters from the approach path 35 and gets on the carrier 9 of the elevator 2. The tire 60 is located immediately before the front stopper mechanism 26.

The steering wheel is straight ahead. This is because you have gone straight on approach road 35.

 The driver gets off without applying the side brakes.

 FIG. 1 shows this state.

Whether to raise the front stopper piece 28 or the rear stopper piece 27 depends on the following.

If there is a parking booth at the back of this car, raise the front stop strip 28 on the opposite side. If the parking booth is in front, raise the rear stop strip 27 on the other side.

 The rear hoisting device 33 is driven.

 The swing frame 10 tilts forward.

The car 50 moves forward under its own weight. Tire 60 is the front stop piece
Hit 28. The forward movement stops. This is stable.

 The elevator 2 is lifted by the lifting device 3.

This state is shown in FIG. The carrier 9 is tilted forward. In this state, the car is selected. Because it is tilted, it never falls backwards.

 And it will be placed in the parking booth on the rear of the 4th floor.

 This is shown in FIG.

Stop elevator 2 on the 4th floor. The rear hoisting device 33 is rewound.

The front winding device 34 is wound up. The rocking table 10 tilts in the opposite direction.

The rear axis 20 and the bearing 23 are in contact with each other, and the carrier 9 is tilted rearward with this as a fulcrum.

The vehicle 50 starts to move backward due to its own weight. The rear tire moves from the carrier 9 to the parking garage 41.

 The car 50 moves further because the parking pedestal 41 is also tilted.

Since the steering wheel is stopped in the straight-ahead position, the car makes a straight-ahead motion in free movement.

 The tire 60 hits the stopper piece 45.

 The car stops.

In this way, the car can be brought into the parking booth 40.

 The elevator 2 stands by at any place.

 Next, the delivery will be described.

For example, suppose you want to bring out the car 53 in the parking booth on the third floor.

 Raise elevator 2 to the exit position on the 3rd floor.

 The leaving direction is the movement from the back to the front.

In the elevator 2, the carrier 9 is tilted in the direction of the leaving movement.

 In this case, tilt forward.

The end of the carrier 9 and the inner end of the parking 41 are smoothly connected.

 Raise the front stopper strip 28.

At the parking booth 40, drive the platform lifting mechanism 44 to
Raise the outer edge of 41.

Due to its own weight, the automobile 53 starts moving inwardly on the slope inclined inward.

 It moves smoothly and enters the carrier 9.

 This state is shown by a one-dot chain line.

Eventually, the tire of the automobile 53 hits the front stopper piece 28.
Free running of the automobile 53 stops.

The elevator 2 is lowered to the entry / exit position 36 while maintaining such an inclination.

 The hoisting device 33 is rewound, and the carrier 9 is returned horizontally.

In this way, the same state as in FIG. 1 is obtained. Move the car backwards and take it out from the approach road 35.

 This means that the goods have been issued.

As can be seen from the above description, the elevator entrance and exit positions are different in the vertical direction.

 The warehousing position is always higher on the same second floor.

 This will be described with reference to FIG.

The parking pedestal 41 tilts around the support shaft 41 (point M). Upon receipt
Become PM. At the time of storage, the elevator carriage 9 is at the GF position.

At the time of leaving the warehouse, the parking pedestal 41 becomes NM. The carrier is HE.

AC is the vertical line passing through the center line of the rear axis 20. Axis 21
The vertical line passing through the center line of is BD.

Since the lower axis serves as a fulcrum, points A and D are fulcrums for loading and unloading.

Let X be the vertical foot from the point A on the straight line BD. XD = h
And

The height of the elevator is different by h when entering and leaving.

Elevator height is an important control variable. There should be no difference in height from the parking lot.

In order to regulate the height correctly, the stabilizer shown in FIG. 5 is used. Fixed metal fittings 31, movable metal fittings 62
Let h be an integer multiple of.

np = h Stop the elevator while detecting the height of the elevator using the limit switch.

It suffices that the vertical control accuracy of the lifting device 3 is finer than the pitch p of the chevron teeth. The elevator may stop slightly above and below the pitch p. This is because if the movable fitting 62 is pressed against the fixed fitting 31, the position of the elevator 2 is corrected.

As described above, if there is a fear of malfunction during parking, a movable stopper mechanism 46 and a safety stopper 49 as shown in FIG. 4 may be provided.

In this way, even if the parking platform 41 is lifted due to a malfunction,
50 does not fall.

(F) Effects (1) Since it is a multi-storey parking lot, it is possible to use the narrow land extremely effectively. You can park 2 (N-1) cars on the Nth floor.

This device is extremely elongated. If you have a lot of land, you can install several of the same in parallel.

(2) In conventional multilevel parking lots, cars with side brakes are placed on a pallet to move.

For this reason, a power source such as a conveyor or a roller is required. Since a large pallet is translated, the conveyor is large and the number of rollers is large.

 It was extremely expensive and the equipment was expensive.

 The present invention does not use pallets.

The car is moved by free running of the car using the slope.

 No power source required.

 No conveyor required.

 No need for many rollers.

 Facilities and equipment are simplified.

(3) Those using a pallet require a pallet-only storage space, a pallet-only carrier, or the movement of the elevator is doubled.

Since the present invention does not use a pallet, the movement of the elevator during loading and unloading is simple.

 The warehousing time is short.

(4) Since the loading and unloading time is short, the number of cars that can be handled by the elevator car is large, and it can be used as a multi-storey car park on a higher floor.

 The efficiency of land use can be improved.
