Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a two-stage multilevel parking system, and more specifically, a parking pallet can be raised and lowered from two pillars erected on the platform. The present invention relates to a two-stage multilevel parking system in which the parking pallet is raised and lowered by chain blocks.

(Prior Art) A two-level multilevel parking system usually has one or two parking pallets that can be raised and lowered, and one parking pallet (or the upper parking pallet in the case of a system with two parking pallets) is placed on top of the parking pallet. While one vehicle is loaded and raised, another vehicle is parked below it (on the lower parking pallet in the case of a vehicle with two parking pallets).

Traditionally, multilevel parking systems with this configuration have been complex and large-scale, with many having four pillars in consideration of the strength to support the weight of parked vehicles, and the drive mechanism for the parking pallets using hydraulic cylinders. Ta. For this reason, the supports (especially the front supports) may get in the way when the vehicle enters or leaves the vehicle, causing problems in changing direction, and often causes failures in the pallet drive mechanism.

Therefore, in order to solve this difficulty, we decided to use two pillars and -
The parking pallet is raised and lowered by an electric winch along the pillars via wires, and a link mechanism such as a pantograph is provided so that the parking pallet can be raised and lowered while maintaining a horizontal state. A multilevel parking system has been devised. In this multi-level parking system, when the parking pallet is raised, another vehicle is parked directly below the parking pallet.

[Problem to be solved by the invention]

The conventional multilevel parking system does not have a guide member for the parking pallet other than a pantograph-type link mechanism to keep the parking pallet horizontal, and when the parking pallet is lifted by a wire, the link mechanism naturally extends. Since the parking pallet is only moved horizontally, there is a risk that the parking pallet on which the vehicle is placed may not be stable at the upper limit position. It is clear that the center of gravity of a parked vehicle is not always in the same position, and it is unknown whether the vehicle will face forward or backward when parked, so consider that the center of gravity of a parked vehicle will vary over a considerable range. Then, the above-mentioned drawback that the raised parking pallet cannot be stably held is extremely serious from the viewpoint of safety.

In addition, in this conventional multilevel parking system, the wire is moved along a pulley attached to a support, and the wire is wound up with an electric winch.
There is also the risk that the wire may come off the boob and cause the device to become inoperable.

Therefore, an object of the present invention is to have a simple structure with few failures, to stably hold a parking pallet even at the upper limit position regardless of the type of parked vehicle or parking direction, and to prevent the parked vehicle from changing direction. It is an object of the present invention to provide a two-stage multilevel parking device that is easy to use.

[Means to solve the problem]

In order to achieve the above object, the present invention includes: a platform (10); two columns (21) having guide grooves (21a) erected in the platform (10); and the columns (21). Parking pallets (31
), and a parking pallet (31) supported by the pillar (21).
A chain block (23) for lifting the parking pallet (31), and two rod-shaped supports (21a) fitted into the guide grooves (21a) of the two pillars (21) attached to both sides of the parking pallet (31). 32), and the chain block (23) allows the parking barrel l-
(31) is characterized in that the support member (32) moves along the guide groove (21a) when the support member (31) is moved up and down.

A guide wheel (42) that rotates within the guide groove (21a) can be attached to the support member (32).

[Function] As a result of the above configuration, the parking pallet (31) is supported movably up and down by the two pillars (21) and the two rod-shaped supports (32), and the parking parts l are supported by the chain block (23). - (31) was lifted up, so
Since the structure is simple and the only means for lifting and lowering the parking pallet (31) is the chain block (23) for hoisting the parking pallet (31), there is very little risk of failure.

In addition, the two rod-shaped supports (32) attached to both sides of the parking pallet (31) move up and down while being fitted into the guide grooves (21a) of the two pillars (21), so the parking pallet (31) ) cannot be displaced in any direction other than vertically. Therefore, the parking pallet (31) is stably held both during elevation and at the upper limit position.

Furthermore, a column (21) that supports the parking pallet (31)
Since there are two pillars, when changing the direction of the vehicle, the pillars (21)
never gets in the way.

If the support member (32) is provided with a guide wheel (42) that rotates within the guide groove (21a), the guide wheel (42) will hit the wall of the guide groove (21a) when the parking pallet (31) is raised or lowered. Since it rotates, it can be moved up and down smoothly.
