Description

[Detailed Description of the Invention] The present invention is different from conventional gondola-type or slow-open type multilevel parking facilities, and consists of a parking shelf and a transverse frame having a car lift platform, and is easy to disassemble and reassemble. The aim is to provide multi-level parking facilities.

Embodiments of the present invention will be described below with reference to the drawings.

In Figures 1 and 2, 1 is a parking shelf, which consists of a large number of parking floor plates 2 and pillars 3, and has multiple tiers (for example, 3 tiers) and double rows of car storage compartments 4a..., 4b.・・・・・・、
It is erected on the floor or ground 5 so as to have a height of 4c.

Reference numeral 6 denotes a transverse frame as a reference, which can be operated transversely on the floor-crossing ground 5 parallel to the front of the parking shelf 1, that is, in the double row direction A.

Reference numeral 7 denotes a car elevating platform which can be operated up and down within the transverse frame 6 between the multiple car storage compartments of the parking shelf 1.

Although not shown, two parking shelves may be provided and the traversing frame may be made to traverse between them.

Reference numeral 8 denotes a traversing drive device for the traversing frame 6, which includes tire-type wheels 9 provided at the bottom of the traversing frame 6, guide rollers 11 fitted to rails 10 buried in the floor or ground 5, and the wheels 9. It consists of an AC/DC dual-purpose electric motor for driving the shaft 12 and a storage battery.

Reference numeral 13 denotes an elevating and lowering drive device for the vehicle elevating platform 7, which is constructed as shown in the schematic front view of FIG. 3 and the schematic plan view of FIG. 4.

That is, the four outer supports 14a, 14 forming the transverse frame 6
A pair of lift cylinders 15 mounted on two of the lift cylinders 14a, a sheave 1T pivotally supported on the upper end of each piston rod 16, and one end fixed to the protrusion 18a of the lifting platform T and the coupe. A pair of chains 20, the other end of which is fixed to the protruding piece 19 of the support 14a via 1γ, and the support 1
A sprocket 21 pivoted to the lower part of the other support 14b, a sprocket 22 pivoted to the lower part of the other support 14b, a sheave 23 pivoted to the upper part, and the protrusion 1 of the lifting platform T.
One end is fixed to 8a, and the other protruding piece 18b of the lifting table 7 is connected via sprockets }21, 22 and the sheep 23.
a pair of chains 24 whose other ends are fixed, a synchronization shaft 25 that integrally connects the pair of sprockets 22, a hydraulic unit that supplies pressure oil to the lift cylinder 15, and the AC/DC dual-purpose electric motor. It consists of

Therefore, when the pair of lift cylinders 15 are extended by L,
The chain 20, that is, the lifting platform 1, is pulled upward by 2L,
In addition, one chain 24 is also pulled up by 2L on the protrusion 18a side, so that the sprockets 21, 22 and the sheave 2
3, the lifting platform 7 is pulled up by 2L on one protrusion 18b side.

Furthermore, due to the fact that the pair of sprockets 22 are integrally rotated by the shaft 25 and the above-described structure, the pair of lift cylinders 15 are synchronized and the lifting platform 7 is always raised by the same amount at the four corners. .

Of course, the lowering of the lifting platform 7 by shortening the lift cylinder 15 is also carried out horizontally for the above-mentioned reason.

Next, the elevating and lowering guide device for the elevating platform will be explained based on the schematic plan view in FIG. 5 and the schematic side view in FIG. The outer row 2 is pivotally supported at the four corners of the lifting platform 7 so as to roll on the top.
26, and a total of four groove-shaped rails 27a, 27, two of which are adjacent to each other in the front and rear, and each facing left and right S at the center of the transverse frame 6.
b, a total of four inner rollers 28 that fit two into each rail and roll, and a pair of left and right brackets 29 that support the rollers on the elevator platform I.

In addition, since the inner rollers 28 are disposed close to each other, two on each side, four on each side, even if the lifting platform 7 is slightly tilted, the vertical deviation between the four inner rollers on each side will not occur. Extremely small, the rollers and inner supports 27a, 27b
The friction between them will not increase.

3. Figures 7 and 8 show the steps and gaps provided between the platform 7 and the floor or ground 5 or the parking floorboard 2 of each vehicle storage compartment to allow the vehicle C to move smoothly. 2 shows the installed splash plate 30 (see FIG. 2) and its opening/closing device. During descent, it also functions as a stopper to prevent the car C from accidentally falling from the platform.

The splash plate 30 is connected to the front and rear ends of the lifting platform 10 via a horizontal shaft 31 so as to be rotatable between a vertically closed state and a horizontally open state.

A DC motor 33 mounted on a 41 case 32 provided at the side end of the lifting platform 1, a torque limiter 34 mounted on the rotating shaft of the motor, and a drive side sprocket 35
, a chain 36, a driven side sprocket}37, 38, a sprocket 39 integrally connected to the sprocket shaft 31, and a chain 40 hooked between both sprockets 38, 39 constitute a sprocket opening/closing device.

In addition, 41 is a manual opening/closing device for the splash plate, which is connected to chain 36.
A tensioner sprocket 42 engaged with the sprocket 42, a sprocket 43 integral with the sprocket 43, a manual handle 45 supported by a bearing 44 of the case 32, a sprocket 46 integral with the handle, and a sprocket 43 integral with the sprocket 43. It consists of a chain 47 that is hung at the same time.

When the voltage of the storage battery decreases, the DC motor 33
Since it is not driven, by rotating the manual handle 45 and rotating the chain 47 and sprocket 42, the chains 36 and 40 are rotated, thereby opening and closing the splash plate 30.

FIG. 9 is an electrical circuit diagram of the splash plate opening/closing device, which is designed to protect the DC motor and reduce power consumption of the storage battery.

In the figure, 48 is the armature of the DC motor for opening and closing the splash plate, 49 is the field coil of the same motor, 50 is a normally open relay contact for lowering the splash plate, 51 is a normally closed relay contact for lowering the splash plate, 52 is a normally open relay contact for raising the splash plate, 53 is a normally closed relay contact for lowering the splash plate, 54 is a lowering push button, 55 is a rising push button, and 56 is opened when the splash plate is lowered to its lowest position. 51 is a limit switch that opens when the splash plate reaches the highest level, 58 is a relay 50
59 is a non-contact timer, 6
0 is a relay coil, 61 is a normally closed relay contact operated by the relay coil 60, and 63 is a relay coil that operates the relay 52.

Therefore, when the push button 54 is pressed to lower the splash plate, the limit switch 56 is connected, so the relay contact 61
The relay coil 58 operates, the contact 50 operates, and the contact 5
3 is normally closed, so the DC motor works and the splash plate begins to descend.

Therefore, the descending moment due to the weight of the splash plate 30 is applied to each component of the closing device (electric motor 33, torque limiter 34, sprockets 35, 37, 38, 39, chains 36, 40).
After a certain period of time has elapsed to overcome the frictional force that tries to prevent rotation, the non-contact timer 59 activates, causing current to flow through the relay coil 60. Since the contact 61 stops operating, the relay coil 58 does not work, and therefore the relay contact 50 does not operate, the electric motor stops, and the spring plate 30 then descends due to its own weight, but because of the frictional resistance of each component that makes up the spring plate opening/closing device, it descends at a low speed.

When the splash plate is at its lowest position, the limit switch 56 should not be opened.
Even if the lowering push button 54 is operated thereafter, the electric motor will not be driven.

Further, when the splash plate is to be raised, when the push button 55 is pressed, the relay coil 63 is operated and the relay contacts 52 and 51 are connected, so that the electric motor is activated to raise the splash plate.

When the splash plate reaches its highest position, the limit switch 51 opens and the motor stops.

As mentioned above, since a timer is used, the splash plate will descend under its own weight after a certain period of time, so even if there is a level difference between the elevator platform and the parking floor, the motor will not continue to drive.
Electric motors are protected.

Furthermore, since the time for driving the electric motor is short, the power consumption of the storage battery can be reduced.

As shown in FIG. 1, operation panels 62a and 62b are provided on both sides of the platform 70, so that whether the vehicle C is carried forward or backward to the platform T, the driver can remain seated in the seat. It is possible to operate the operation panel 62a or 62b while sitting on the seat.

The layout of the switch buttons on the operation panel is designed as shown in FIG.

In addition, all of the above-mentioned parts are assembled with bolts so that they can be disassembled and reassembled, making the parking facility transportable and easily assembled for use in various gathering spaces, etc. .

Next, the parking method in the above embodiment will be explained.

First, the car C is carried onto the elevator platform T at its lowering limit with the splash plate 30 open, and while sitting on the seat, operate the operation panel 62a or 62b to close the splash plate 30. At the same time, the lifting platform 7 is raised, the splash plate 30 is opened, and the car C is carried into a desired car storage compartment. Return to original position.

Of course, the method for taking out the parked car C can be carried out by following the above procedure in reverse.

As is clear from the above description, the present invention provides a parking shelf that is erected on the floor or the ground so as to have car storage compartments in multiple stages and rows, and a parking shelf that is erected on the floor or the ground in front of the parking shelf. a base frame, a car lifting platform that can be operated up and down between the multiple car storage compartments of the parking shelf within the base, and a lifting drive device thereof, The spring plate, which has the same width as the car lift platform, is connected via a horizontal shaft so as to be rotatable between the vertically closed state and the horizontally open state, and the spring plate is placed in the horizontally open state when loading and unloading the car. A splash plate opening/closing device is provided for vertically closing the vehicle when the vehicle is raised or lowered, and the electrical circuit of this device includes an electric motor for opening and closing the splash plate and a switch for switching the splash plate from the closed state to the open state. A timer is provided which operates to stop the electric motor after a certain period of time has elapsed from the start until the splash plate reaches a position where it can fall under its own weight.

Therefore, according to the present invention, a parking shelf with a simple frame structure,
A base frame with a simple frame structure having a lifting platform for simple lifting and lowering can be easily disassembled and reassembled.

Furthermore, in the present invention, even if there is a step or a gap between the car elevator platform and the floor, one ground, or the parking floorboard of the car storage compartment, it is possible to cover this with a splash plate and move the car smoothly. It is safe because it prevents the car from falling unexpectedly while going up and down.

Moreover, the electric circuit of the splash plate opening/closing device is equipped with a timer that operates to stop the motor after a certain period of time has elapsed from the time the splash plate starts lowering. Even if the vehicle descends and there is a step between the elevator platform and the parking floor, the motor will stop without continuing to drive, protecting the motor and therefore reducing the time it takes to drive the motor.
This has the advantage of requiring less power consumption from storage batteries.
