Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a two-stage parking apparatus capable of moving a vehicle such as an automobile up and down to increase a parking space.

2. Description of the Related Art Conventional technology and its problems As a two-stage parking device of this kind that can secure a double parking space in the same parking area, there has already been a device that elevates and lowers an elevating plate with a drive device such as a hydraulic cylinder. Is generally known.

By the way, in this known device, for example, a hydraulic pump for feeding pressure oil into the hydraulic cylinder, a motor as a driving member thereof, a hydraulic tank, etc. are installed on the ground in the vicinity of the hydraulic cylinder. However, there is a problem in that it takes a long time to work because most of the work must be done on site during installation. Further, when the two-stage parking is not performed, the upper surface of the lift plate at the lower limit position protrudes from the ground surface, and even if a load is placed, the load tilts near the boundary, so the surroundings of the lift plate are effectively used. There was also a problem that I could not do it.

Therefore, the present invention solves the above-mentioned conventional problems, can save the above-ground space for installation, can reduce the on-site construction, and can perform the installation work in a short time and easily, Further, it is an object of the present invention to provide a two-stage parking device capable of preventing the upper surface of the elevating plate at the descent limit position from protruding from the ground surface when the two-stage parking is not performed.

Means for Solving the Problems In order to solve the above problems, the present invention provides the above-mentioned 2
In the stepped parking apparatus, a recess having a predetermined depth is formed on the lower surface of the lift plate, and the pump, tank, and drive member are installed in the recess without protruding downward from the lower surface of the lift plate. It is characterized in that a recess that can be housed is formed on the ground surface below the lifting plate so that the upper surface is substantially flush with the ground surface at the lower limit position.

Action With the above configuration, it is not necessary to install the hydraulic pump, its drive member, and the tank on the ground, and it is not necessary to secure a space for it. Moreover, since the pump and the like can be installed in advance in the recess of the lifting plate in the factory,
On-site construction is reduced. Further, when the two-stage parking is not performed, the elevating plate at the lower limit position is housed in the recess so that the upper surface thereof is substantially flush with the ground surface.

Embodiment 1 In FIGS. 1 to 3, reference numeral 1 denotes a two-stage parking apparatus. The parking apparatus 1 has a rectangular shape when viewed from above and includes an elevating plate 2 made of an iron plate or the like. The lift plate 2 is composed of a top plate 2a, end plates 2c hanging from both edges of the top plate 2a, and the like.
The front lower surface of the end plate 2c is formed as an inclined surface that is inclined upward. The height h of the end plate 2c is, for example, about 150 mm, and the height of the end plate 2c forms a recess 3 on the lower surface of the lift plate 2 for installing a hydraulic pump or the like described later. 2d is a reinforcing plate vertically and horizontally provided on the lower surface of the top plate 2a of the lift plate 2, and 5 is the lift plate 2 such as the upper end of the piston rod of the hydraulic cylinder described later.
A pair of mounting plates 5 are provided by bolts 6 at appropriate positions on the lower surface of the top plate so as to balance the lifting plate 2 up and down.

On the other hand, a pipe 8 having an upper opening is buried on the ground where the elevating plate 2 is arranged at a position facing the mounting plate with the opening surface of the pipe 8 close to the ground surface. The pipe 8 is firmly fixed by concrete 9 placed around it. Inside the pipe 8, a hydraulic cylinder 10 and a guide cylinder 11 for guiding a pillar, which is integrated with the hydraulic cylinder 10, are fitted so that the outer surface thereof closely contacts the inner surface of the pipe 8.

The upper end of the piston rod 12 of the hydraulic cylinder 10 thus installed and the upper end of the hollow support column 13 that moves in the guide cylinder 11 are fixed to the mounting plate 5. Cylinder 10
Inside the chamber 10a and the chamber 10b partitioned by the piston 15,
As shown in FIG. 4, one ends of pressure oil hoses 16 and 17 are connected to each other, and the piston 15 is reciprocated by the pressure oil supplied from any one of the hoses. The other ends of the pressure oil hoses 16 and 17 are connected to the hydraulic tank 18 installed in the recess 3 of the lift plate 2 from the guide cylinder 11 through the support 12.

20 and 21 are a hydraulic pump installed in the recess 3 as well as the tank 18, and a drive motor for rotating the pump forward and reverse, and these tank 18, pump 20 and motor 21 are completely installed in the recess 3 when installed. It is in a housed state and does not protrude below the lower edge of the end plate 2c, which is the lower surface thereof.

One end of an electric wire 22 is connected to the motor 21, and the other end of the electric wire 22 is pulled out to the ground via the guide tube 11 in the support column 13 like the hoses 16 and 17, and is also installed on the ground and is not shown in the figure. It is connected to the forward / reverse switch of the board, and the switch is turned on.
The motor 21 can be driven in the forward and reverse directions.

In FIGS. 1 and 2, reference numeral 23 denotes a stopper which, when the lift plate 2 reaches the upper limit position, is locked in a not-shown locking hole formed in the post 13 to prevent the lift plate 2 from being lowered unexpectedly. It is like this. The stopper 23 is locked automatically when the lift plate 2 reaches the upper limit position, and when it is lowered, the lock is automatically released in conjunction with the turning on of the reverse rotation switch. Of course, if you do not do this, the driver etc. directly
The stopper 23 may be manually locked or unlocked. 33 is a recess formed on the ground surface for accommodating the lifting plate,
The lift plate 2 at the lower limit position is housed so that its upper surface is substantially flush with the ground surface. When such a recess 33 is formed on the ground surface, when the two-step parking on the lift plate 2 is not performed,
The surroundings of the lift plate 2 can be made in a state in which no obstacle is projected, and the ground surface can be effectively used.

In the above, the hydraulic tank 18, the pump 20, and the motor 21 are assembled in advance in the recess 3 of the lift plate 2 at the factory. Further, the hydraulic cylinder 10 and the guide cylinder 11 are similarly preassembled.
Therefore, in this parking apparatus, the work on the site is only the formation of the recess 33 on the ground surface and the installation of the pipe 8, which makes the construction on the site very easy and requires a short working time. That is, after the site construction in which the recess 33 is formed and the pipe 8 is installed, the cylinder 10 and the guide cylinder 11 are fitted, and then the mounting plate 5 which is also pre-welded to the upper ends of the piston rod 12 and the support 13 is lifted up and down. It is only necessary to fasten with bolts 6 in place of 2 above.

Next, a procedure for parking the vehicle A on the lift plate 2 will be described.

In the chain line state of FIG. 1 in which the lift plate 2 is housed in the recess 33 and is at the descent limit position, the vehicle A is backed from the front of the lift plate 2 and placed on it, and then stopped at a predetermined position. Turn on the switch to rotate the motor 21 forward. This allows the pump 20
Is rotated normally, and the pressure oil in the tank 18 is supplied to the chamber 10b of the cylinder 10 via the hose 17. The supply of this pressure oil causes the piston 15 to move forward, and the piston rod 12 causes the lifting plate 2 to move.
Is raised.

Upon the ascent, the column 13 also moves upward in the guide cylinder 11. The pressure oil contained in the chamber 10a of the cylinder 10 is returned to the tank 18 via the hose 16. Then, when the lifting plate 2 reaches the rising limit position which is the parking height as shown by the solid line in FIG. 1, the forward rotation switch is turned off, and
The stopper 23 is locked in the locking hole of the column 13. This completes the parking of the vehicle A by the elevating plate 2, and another vehicle B can be parked below the elevating plate vacated by the elevating plate 2 as shown in FIG.

On the other hand, to stop the parking for driving the vehicle A, after moving the vehicle B, the reverse rotation switch is turned on and the motor 21 is rotated in the reverse direction. As a result, the stopper 23 is unlocked, the pump 20 is reversed, and the pressure oil in the tank 18 is transferred to the hose.
It is supplied to the chamber 10a of the cylinder 10 via 16. The supply of this pressure oil causes the piston 15 to return and the piston rod 12
The elevator plate 2 is lowered by the recess, which is the original standby position.
When it reaches the descent limit position accommodated in 33, the reverse rotation switch is turned off. Also at this time, the pressure oil contained in the chamber 10b of the cylinder 10 is returned to the tank 18 via the hose 17.

The above embodiment is merely an example, and the detailed design such as the specific shape and structure of the lift plate 2 and the number of hydraulic cylinders 12 to be installed can be arbitrarily selected.

Effect of the Invention This invention has the above-mentioned configuration, and the hydraulic tanks, pumps, etc., which were conventionally installed on the ground, are installed in the recesses of the lift plate, so the space above the ground for installing these is saved. Therefore, it is possible to effectively use the space in a small parking lot. Further, since it is possible to assemble it in advance at the factory, it is possible to greatly reduce the on-site construction, and it is also possible to shorten and facilitate the installation work. Furthermore, since the upper and lower plates at the lower limit position can be housed in a recess whose upper surface is substantially flush with the ground surface when the vehicle is not parked in two stages, there are no obstacles where the parking device is the same as the ground surface. Therefore, there is an excellent effect that 100% of the ground surface can be utilized, for example, luggage can be placed without tilting and it can be used as a warehouse.
