Due to the explosion of vehicles, securing parking spaces has become a social problem.

In particular, in areas with dense houses, such as urban centers, there are frequent conflicts among residents due to parking, as well as damages caused by fires due to blocked entry of fire trucks when fire occurs by vehicles parked on the back road or illegal parking vehicles. Serious problems may arise.

Due to such problems, the law now requires a sufficient parking space for newly constructed buildings.

However, existing buildings have no special measures to secure parking spaces, and parking problems are expected in the future.

In order to solve the parking problem, various parking facilities have been developed and installed. The parking facilities can be classified into a pallet type, a fork type, and a rotary type according to their structural characteristics.

In the pallet method, when a car to be parked is placed on the pallet, the pallet is lifted or transported to be stored together with the pallet.

In the fork method, lifts are raised and lowered at a certain position, and the fork is stored in a parking space at a specific position. When the tray is moved to the lower position of the parking space, the parking is moved to a proper position. The vehicle is to be lifted and released.

The rotary system allows each parking lot to be rotated by a chain or suspended by a circular frame.

However, the above parking facilities are mostly suitable for underground parking facilities, so it is difficult to apply to existing buildings and difficult to adopt because of the enormous cost.

Exceptionally, the rotary system can be installed on the ground, but it is inefficient because the entire parking facility must be moved in and out of one vehicle, and the parking capacity is very low compared to the facility space.

The present invention has been made to solve the problems according to the prior art as described above, it is possible to reduce the cost burden for the installation of large-scale parking facilities, and to provide a parking lift apparatus that can be installed in a narrow place. .

In order to achieve the object as described above, the present invention has a support frame fixed to the ground to the wall, a multi-joint lever portion coupled to the support frame, and a boarding table coupled to the end of the articulated lever portion A parking lift apparatus, wherein the articulated lever part comprises: a fixed shaft fixedly coupled to the support frame and sequentially connected using a plurality of levers to form a joint structure, and having a plurality of sprockets fixedly coupled thereto; A rotating shaft rotatably coupled to the distal lever of the lever coupled to the fixed shaft to form a joint, and the plurality of sprockets fixedly coupled; A chain connected to the sprocket of the fixed shaft and the rotating shaft; And a plurality of hydraulic cylinders for driving the joint structure.
