Description

[Detailed description of the invention] The present invention relates to a multi-story parking lot.

Conventional multi-level parking garages use a merry-go-round system in which the parking shelves themselves circulate, or a high-rise elevator system in which carts loaded with vehicle-mounted pallets are carried via an elevator to a designated floor and then transported to a designated storage location using a trolley. Many integrated types have been adopted, which are complex and expensive in structure and require a large amount of installation space.

Moreover, many of the fixed position stopping devices for elevators are electrical, and their control is complicated.

The present invention employs, for example, a birkin knotlet in a parking shelf, which can be transported to a predetermined floor by a lift, and has a simple structure that detects the upper and lower positions of the fixed stop position of each parking floor using a mechanical fixed-position stop device. We propose a multilevel parking lot that is extremely easy to control using detectors.

In order to achieve the above object, the present invention has a lift that can go up and down along an erected parking frame, a stopper that can go out and go out, and a stopper on each parking floor of the parking frame. A stepped portion is provided at a position corresponding to the fixed position to engage with the stopper to regulate the stopping position of the lift, and a stepped portion is provided to regulate the stopping position of each parking floor, and the step portion is provided to regulate the stopping position of each parking floor, and A detector is provided that detects upward and slightly downward directions, and when a parking floor is designated and the detector detects that the ascending lift is above the fixed stopping position of the designated parking floor, the lift stops and the stopper protrudes or retreats. At the same time, when the parking floor is specified, the detector detects that the lowering lift is lowered below the fixed stop position of the designated parking floor. When the lift is detected, it is configured to cause the lift to move upward.This not only makes it possible to easily and reliably mechanically stop the lift in a fixed position using a stopper, but also to prevent the lift from rising. Even if the lift is lowered by the lift, the stopper can be used to stop the lift at a fixed position.

An embodiment of the present invention will be described below based on the drawings.

Figure 1 shows the overall structure, and the framework of the parking lot consists of an upright flat parking frame 1, which can be raised and lowered along the front surface of its short side, and holds a parking pallet 2 in a cantilevered manner in a detachable manner. The lift 4 has two upper and lower horizontal guide rails 3, 3', and two of the lifts 4 are located on both long sides of the front king frame 1 at positions corresponding to each floor as shown in Fig. 2. Two upper and lower parking horizontal guide rails 5゜5' corresponding to the book horizontal guide rails 3 and 3' are fixed in the width direction of the long side of the parking frame 1, and the pallet 2 can be freely removed like the lift 4. It is constructed so that it can be held in a cantilevered manner, forming a multi-level parking lot with multiple levels above and below.

The extension of the solenoid 41 causes the main body 11 to protrude outward on both sides, and then, as the lift 4 descends, it engages with a step 45 provided inside the parking frame 1 as shown in FIG. The lift 4 is then stopped.

At this time, the two horizontal guide rails 3, 3' of the lift 4 and the two parking horizontal guide rails 5, 5' fixed to the side surfaces of the parking frame 1 are on the same level.

Note that when the lift 4 is started from a predetermined floor, the lift 4 is once raised slightly when ascending or descending, and the stopper 45 is not housed inside the main body 11 by the contraction action of the solenoid 41, and the lift 4 is It is difficult to go up and down.

In FIG. 2, the lowest level of the parking lot is formed as a cargo handling area 46 for storage vehicles, and a mud switch 41 is provided on the ground to ensure safe operation of the lift 4 for storage. As long as there are cars or people on the lift 41, the lift 4 will not operate.

Further, a control panel 48 is provided at the bottom of the parking frame 1, and has a built-in function for automatically controlling the loading and unloading of vehicles.As shown in FIG. Key switch 5 for each floor and left and right parking spots on each floor

The key 56 of the key switch 50 remains inserted into the key switch 50 in a non-removable state after the car is taken out, as in a normal coin locker, and cannot be removed after the car is brought in.

Next, an example of the operation will be explained based mainly on FIGS. 10 to 14.

If you want to park, first select the key switch 50' where the key is inserted (this means that there is no parked car), and turn the key from the center side N to the doorway.

At this time, all other key switches 50 are locked.

Assuming that the key switch 50' is selected for the left parking spot on the 5th floor as shown in Figure 2, if the lift 4 is stopped below the 5th floor, it will rise and the striker 51 attached to the lift 4 ( FIG. 8) stops when the actuator 59 of the limit switch 58 installed on the fifth floor is moved from the position 59' as shown in FIG. 9 to the position 59' as shown in FIG.

That is, when the lift 4 reaches the upper limit level position a from below as shown by the dotted line, it stops, and the fixed position stopper 42 is caused to protrude outward on both sides of the main body 11 via the solenoid 41.

Then, after a predetermined time lag, it descends and the above-mentioned position spring
42 to the stepped portion 45 of the parking frame 1 corresponding to the 5th floor.

Also, if the lift 4 is stopped above the 5th floor, it will descend and its striker 57 will be activated by the limit switch 5 on the 5th floor.
The actuator 8 stops when the actuator 59 is moved to the position 59' as shown in FIG.

That is, the lift 4 stops when it reaches the lower limit level position C from above as shown by the solid line.

Next, after a predetermined time lag, the striker 57 rises, and the striker 57 again activates the actuator 59 of the limit switch 58.
When it is displaced to the position ', it stops at the upper limit level position a, the fixed position stopper 42 is protruded as described above, and after a predetermined time lag, it descends and reaches the fixed position C via the fixed position stopper 42 and the stepped portion 45. Stop.

The predetermined floor stopping device 60 shown in FIG. 14 represents the block.

At this time, the two horizontal guide rails 3, 3' of the lift 4, which has stopped at the fixed position, are replaced by the two parking horizontal guide rails fixed to the side of the parking frame 1, as shown in FIG. It is located at the same level as 5 and 5'.

Next, the lift 4 drives its motor 24 to rotate the turntable 21, 21' to the left about the rotating shaft 20.

This is the same as long as the left parking key is selected, and the turntable drive device 61 shown in FIG. 14 is a block thereof.

At this time, the pallet moving sprocket 25 of the turntable 21' engages with the rack chain 12 of the empty pallet 2 held on the parking horizontal guide rails 5, 5' as shown in FIG. The member 62 pushes a horizontal slide rod 63 provided on the side surface of the parking frame 1, pushes up the stopper 31 shown in FIG. 5 appropriately, and releases it from the stopper groove 13 of the pallet 2.

Next, the lift 4 drives the motor 28, pulls out the pallet 2 to the turntable 21, 21' side via the sprocket drive gear 2γ, the intermediate gear 26, the pallet moving sprocket 25, and the rack chain 12, and hooks the pallet 2 horizontally. The rollers 10, 10'11 of the guide plates 9, 9' are connected to the horizontal guide rails 3, 3' of the turntable 2L21'.
The pallet is placed on the pallet and held in place, and the position is fixed with the pallet fixing stopper 29.

FIG. 12 shows this state, and the pallet transfer device 64 in FIG. 14 is a block diagram thereof.

Next, the lift 4 drives the motor 24 to return the turntables 21, 2V to their original state with their guide rails 3, 3' facing forward.

This is the same as long as you choose the left parking key.

FIG. 13 shows this state, and the turntable driving device 65 in FIG. 14 shows its block.

Next, the lift 4 rises and stops at the upper limit level position a where the striker 51 displaces the actuator 59 of the limit switch 58 to the position 59', and the solenoid 41
The ground floor stopping device 66 shown in FIG. 14, which drives the fixed position stopper 42 and stores it in the main body 11, descends after a predetermined time lag, and stops at the material handling area 46, is the block shown in FIG. The dotted line shows its movement path.

By driving a parking vehicle onto the empty pallet 2 of the lift 4 that has been unloaded at the cargo handling area 46, the weight of the parking vehicle is detected by the detector 61 (Fig. 14), and after a predetermined time lag, the lift 4 rises and the 5 60,6 in Figure 14 when reaching the floor.
1 to perform the same stopping operation and rotating operation of the turntable 2L21' as described above.

In the pallet transfer device 65, the output of the detector 61 is applied, for example, through the gate 68 as shown in FIG.
．． 21' guide rails 3, 3' is sent to the parking horizontal guide rails 5, 5' of the parking frame 1, the pallet 2 mounted on the car is held by the guide rails 5, 5', and the car is moved. Park.

The dash-dotted line in FIG. 11 shows the operating path.

The turntable 21, 21' is then returned to its original position by the turntable drive 65.

At this time, since the output of the turntable driving device 65 is the output of the detector 6γ, which is applied to the gate 69, for example, the key switch 50' is reset to return the key to the neutral side N, and then the key 56 is turned off. The key 56 can be removed from the key switch 50', and the user will keep the key 56.

Then, the parking time display 51 starts and displays parking.

Next, if you want to take out the parked car, insert the ζ9 key into the key switch 50' and turn it from the neutral side N to the unloading side O.

Then, the fee corresponding to the parking time is displayed on the fee display 52.

When the user inserts a coin corresponding to the charge into the coin slot 53, the lift 4 is operated, and the pallet 2 mounted on the car on the left side of the 5th floor is carried out to the handling area 46, following the same route as when carrying it in. .

When a fee receipt is desired, a receipt is obtained from a receipt input port 55 by pressing a receipt request button 54 before the vehicle-mounted pallet 2 arrives at the cargo handling area 46.

By removing the car from the lowered pallet 2, the weight loss is sensed, and the lift 4 rises while holding the empty pallet 2, and stores the empty pallet on the left side of the predetermined 5th floor.
J-Foot 4 stops at that position.

In either case of loading or unloading, the lift 4 will not operate as long as the mud switch 47 of the cargo handling area 46 senses that there is a car, other object, or person above it.

Further, the key switch 50 may be configured to have only positions for the carry-in side and the carry-out side, and the key 56 may be removed from the key switch 50 at the carry-in display position after the lift 4 starts rising for parking. good.

Parking fees can also be configured to be fixed by the hour, fixed by the hour, fixed by the month, or the like.

As described above, according to the present invention, since the lift is stopped by a stopper that can be moved in and out, it is not only mechanically simple, but also allows the stopper to move in and out from the designated parking floor with respect to the lift moving from below. In this way, whether it is an ascending lift or a descending lift, it can be operated simply and stopped at a fixed position with ease.
