JPH08144556A - Driving wheel type two-stage system parking machine - Google Patents

Abstract

PURPOSE: To manufacture a two-stage system parking machine which is simplified like electric work is unnecessary and execution of foundation work is unnecessary and it can be moved to a necessary place or the like in a multistory parking machine which can be vertically moved in a two-stage system by using large horse power possessed by an automobile even in a place having no electric power supply. CONSTITUTION: When a driving wheel 14 of an automobile 15 rotates, oil is pulled out of an oil pressure tank 5 by rotation of a hydraulic pump 4 connected to a motive power transmitting roller 2, and is sent into a hydraulic cylinder 6. A piston 7 is pushed down, and the automobile 15 rises together with the hydraulic cylinder 6 connected to a pedestal.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-stage parking machine which is simplified so that it can be used anywhere regardless of location.

[0002]

2. Description of the Related Art In a conventional two-stage parking machine, a power source is required for a power source, and electrical work is indispensable for that purpose. It was expensive and running costs such as electricity costs were required. When using a hydraulic cylinder, two were required, and the horsepower was limited to around 5 horsepower.

[0003]

SUMMARY OF THE INVENTION By eliminating the power source, which is indispensable for the conventional two-stage parking machine, it can be easily installed and moved, and the large horsepower of a car is utilized.
Easy to move up and down with a book hydraulic cylinder.

An object of the present invention is to operate a pedestal up and down with a single hydraulic cylinder by utilizing the power of the vehicle itself which gets into a two-stage parking machine.

[0005]

In order to achieve the above object, a roller (2, 2 is attached to a pedestal 1 of a two-stage parking machine of the present invention.
3) is attached, and the hydraulic pump 4 is attached to the power transmission roller 2.
The cylinder 6 and the pedestal 1 are connected to each other, and the wire 8 for maintaining the equilibrium of the pedestal 1 is connected to the pillar (9, 1).
It is attached to 0).

[0006]

When the drive wheel 14 rides between the rollers (2, 3) installed on the pedestal 1 constructed as described above and rotates, the hydraulic pump 4 causes oil to be drawn from the tank 5 by the hydraulic cylinder 6.
And the piston 7 is pushed down to raise the pedestal 1 and the hydraulic cylinder 6 at the same time, and the wire 8 maintains the equilibrium of the pedestal 1.

[0007]

[Embodiment] The embodiment will be explained with reference to the drawings.
In FIG. 1, a three-dimensional perspective view of the pedestal 1 when raised,
The illustration of the car 15 is omitted.

In the embodiment shown in FIG. Driven on the pedestal 1, the drive wheels 14 have fallen between the rollers (2, 3).

In the embodiment shown in FIG. 3, the drive wheel 14 rotates and oil is sent from the hydraulic pump 4 connected to the power transmission roller 2 to the hydraulic cylinder 6 and the piston 7 is pushed to rise together with the pedestal 1. I have just done it.

In the embodiment shown in FIG. 4, the wire 8 is fixed to the lower part of the left column 9 for raising the pedestal 1 horizontally by one hydraulic cylinder 6, and the wire 8 is passed over the left balance roller 11 and the right balance roller 12 is provided. Hook 13 on the right pillar 10 from below
It has just been fixed to.

In the embodiment shown in FIG. 5, the pedestal 1 has just been raised horizontally.

In the embodiment shown in FIG. 6, the wires 8 for balancing the pedestal 1 are visible and the arrangement of the parts is shown.

In the embodiment shown in FIG. 7, when the pedestal 1 is raised as a method of operating the hydraulic circuit, the oil 24 is sucked up from the oil tank 5 by the hydraulic pump 4, and the hydraulic pressure adjusting valve 22, the check valve and the check valve are opened and closed. Hydraulic cylinder 6 through valve 18
The oil flows to the flow rate adjusting valve 20 when the check valve 18 is opened and the oil flows back to the oil tank 5 through the hydraulic pressure adjusting valve 22 when the check valve 18 is opened. When the valve 18 is not opened, oil returns from the hydraulic pump 4 to the oil tank 5 through the hydraulic pressure adjusting valve 22.

Since the present invention is constructed as described above, it has the following effects.

A two-stage parking machine can be installed even without a power source.

Since it does not require foundation work, it can be moved.

Since the large horsepower of the automobile is utilized, a large two-stage parking machine can be manufactured.
