[0002]

2. Description of the Related Art In recent years, as the number of automobiles has increased, a multi-story parking system which can accommodate a large number of automobiles in a limited installation space has become widespread in order to secure a parking lot in an urban area or the like.

By the way, the present applicant has filed Japanese Patent Application No. 1-170.
No. 488 proposes a multilevel parking system. This three-dimensional parking system is constructed by arranging a plurality of garage rows in which garages are arranged in opposition to each other, a pallet on which a car housed in each garage of this construction is freely placed, and an opposing structure. , A lifter vertically movable between a plurality of garage rows, a carriage horizontally movable on the lifter, and a carriage arranged on the lifter. And a transfer means for transferring the pallets to and from the garages in each garage line.

In order to store the automobile in the desired garage of the structure, after placing the automobile on the pallet of the truck held at the center of the lifter stopped at the descending end, the lifter is placed in the desired garage line. As the garage rises up to a certain level, the trolley held in the center of the lifter is horizontally moved to face the desired garage, and then the trolley between the trolley and the garage in the garage line is arranged by the transfer means on the trolley. The cars are placed in the desired garage of the construct by transferring the pallets.

By the way, in the above-mentioned multi-level parking apparatus, when moving a car into and out of a garage in a garage line, the carriage is stopped and fixed at the center of the lifter and at a fixed position, that is, in a position facing the garage in the garage line. There is a need.

Therefore, conventionally, a position detecting switch such as a limit switch or a proximity switch is provided at a fixed position of the carriage,
When the carriage moves to a fixed position, the position detection switch electrically stops and holds the carriage.

[0007]

However, when the carriage is electrically stopped and held at the center of the lifter and a fixed position by a position detection switch such as a limit switch or a proximity switch, the control for stopping and holding the carriage becomes complicated. In addition, it requires a large amount of power to stop and hold the truck. Moreover, the weight of the trolley is so heavy that it cannot be stopped instantaneously due to inertia, etc., so the trolley's stopping accuracy is poor. If the carriage has a poor stop accuracy, when the carriage is moved to face the desired garage in the garage row, the pallet loading / unloading rail arranged on the trolley and the garage row garage are arranged. There is a disadvantage that the pallet loading / unloading rails do not coincide with each other in a straight line, which causes a trouble in transferring the pallet between the trolley and the desired garage in the garage line.

The present invention has been made in view of the above problems, and an object thereof is to improve the stopping accuracy of a bogie by accurately and surely stopping and fixing the bogie.

[0009]
