Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application: The present invention relates to a multilevel parking system that raises and lowers a car by using link movements that move in parallel.

Prior art: Various types of multilevel parking systems are used to reasonably secure parking spaces for cars, including those with helical or curved self-propelled passageways, and multi-level parking systems with lifting devices. Because of its simplicity, two-level multilevel parking systems have become widely used.
Most of the latter multilevel parking systems are formed by lifting and lowering the on-vehicle pallet by suspending it from a chain or wire along a support. However, depending on the frequency of use, the chains and wires may stretch, making it difficult to maintain the balance of the on-vehicle pallet. It runs out and has to be adjusted each time. Additionally, those that use chains or wires always require safety equipment in case of cutting, making the equipment complex and expensive accordingly. Therefore, to compensate for these shortcomings, there is a link mechanism that uses a simple structure.
For example, as disclosed in Japanese Patent Publication No. 52-11828 (Patent No. 885464), an automobile is raised and lowered in a horizontal state using link motion forming a parallelogram. This type of device requires a large amount of torque because the driving force to move up and down is generated at the root of the link, and gears are also used to transmit the driving force, which causes a lot of loss, and the structure is complicated, which can lead to failures. It is easy and difficult to maintain. Therefore, there are many problems such as not being able to maintain a balance between profit as a parking device and operating costs.

Problem/Objective of the Invention: The present invention solves these problems by rationally combining a plurality of parallel moving link movements so that only a small driving force is required during lifting and lowering, thereby reducing costs. The purpose of the present invention is to provide a multi-level parking device having many advantages such as a simple structure and a compact external shape.

Structure and operation of the invention: In order to achieve the above object, the present invention provides gate-shaped supports having a required height at least higher than the vehicle height on both sides of the vehicle or the vehicle pallet on which cargo is placed. (Hereinafter, simply referred to as a support body) is erected, and pin shafts are protruded from both outer sides of the support body at appropriate intervals in the vertical direction. Horizontal structural members are laid in parallel on both sides, and pillars each having a hollow portion are erected thereon, and pin shafts are attached to the side plates of the pillars at appropriate intervals in the vertical direction, passing through the pin shafts. The ends of each link piece of the required length are supported between the pin shafts attached to the support body and the column, and a horizontal structural member is placed near the support body side of the link piece that is supported between the upper pin shafts. The three-dimensional parking system is constructed in such a way that the leading end of an appropriate drive device attached to the top surface of the vehicle is axially connected, and a vehicle-mounted pallet connected thereto can be raised and lowered in a horizontal state by the expansion and contraction movement of the drive device.

Further, in the present invention, a guide flange portion of an appropriate width is provided on the front edge of the outer side of the column, one of a pair of guide rollers that clamps this guide flange portion is pivotally attached to a support plate, and the other guide roller is supported. The plate and the support are integrally fixed to the appropriate positions, and two sets of link pieces of the required length are connected between the respective pin shafts attached to the support and the support, and the ends of each of the link pieces are connected. It has a structure in which a connecting link piece of a required length is pivoted between the main parts of the link pieces, and the pallet mounted on the vehicle can be vertically moved up and down.

Furthermore, in the present invention, guide elongated holes are drilled in the upright plate inside the support to guide the two pin shafts protruding from the support when they move up and down, so that the expansion and contraction of the drive device The movement also allows the connected vehicle pallet to be raised and lowered vertically in a horizontal position.

When the multilevel parking apparatus 1 of the present invention thus constructed is used, a car is driven onto the vehicle pallet 2 at the lower limit position as shown in FIGS. 1 and 2. When the key switch 9 provided at an appropriate location (in this embodiment, it is attached to the side of the upright plate 12) is turned on to raise, the hydraulic pump works and the rod 32 of each hydraulic cylinder 31 begins to extend, causing the tip of the rod 32 to The upper link piece 20A pin-connected to 32' is lifted, and the lower link piece 20B is synchronized accordingly, and the support body 3 and the vehicle pallet 2 connected to the respective link pieces 20A and 20B maintain a horizontal state. and rise to the rising limit. At this time, when stopping at the raised position for a relatively short time, the use of a stopper (not shown) may be omitted, and when holding the raised position for a long time, a stopper is used. This stopper has an approximately wedge-shaped outer shape, and its center part is pivoted at a suitable position on the rear side of the support column, that is, slightly below the highest position of the vehicle-mounted pallet 2. Usually, the inclined surface side of the stopper is extended to an appropriate size. When the on-vehicle pallet 2 is in the passing state, it is returned to the support column 3 side, and after passing, the stopper returns to its original position and securely holds the on-vehicle pallet 2 with the notch provided inside the upper end of the stopper. Those that do are effective. After the vehicle-mounted pallet 2 is raised and held, other vehicles are placed under it and parked in a multi-dimensional manner. When lowering the on-vehicle pallet 2, first release the stopper,
By turning the key switch 9 into the lower position and eliminating the pressurization by the hydraulic pump, the on-vehicle pallet 2 moves by its own weight in the opposite manner to the upward movement and descends to the lowered position. (Using a double-acting cylinder,
Needless to say, it may be lowered by operating a hydraulic pump. ) As mentioned above, each link piece 20A, 20B at the upper limit and lower limit is as follows.
Since it is formed in an inclined state that makes it easy to start even when the additional torque is small, the movement at the start of starting can be performed smoothly.

One of the pair of guide rollers 7, 7' that clamps the guide flange portion 6, ie, the guide roller 7', is pivoted to a support plate 8 of an appropriate shape, and the other guide roller 7 is supported by pin shafts 4, 5. Together with the plate 8, it is integrally attached to the center and lower positions of both sides of the support body 3, respectively. The pin shafts 13 and 14 protruding from or penetrating the center and lower parts of the column 10' and the pin shafts 4 and 5 protruding from the support 3 are provided with two pins of the required length. Two link pieces 22A and 22B each having one end pivoted are provided, and both ends of each of the two link pieces 22A and 22B are pivotally supported on pin shafts 4, 5, 13, and 14. Main part 22',
