Description

[0001]
[Field of the Invention]
The present invention relates to a three-column type elevator parking device in which elevator-type parking devices are arranged in three columns in the vertical direction, and more particularly, a three-column type elevator parking device that allows a driver to easily get on and off a vehicle mounted on a pallet. It is about.
[0002]
[Prior art]
Conventionally, it has a main lift that moves up and down in a vertical hoistway formed in a building, and parking shelves provided in multiple stages on both sides along the hoistway. An elevating type parking apparatus has been proposed that transports and stores it in each parking shelf. In order to increase the number of parked vehicles of this lift type parking apparatus, there is a column type lift type parking apparatus that is arranged side by side in the vertical direction (longitudinal direction of the automobile).
[0003]
For example, in a three-column lift parking device, when an automobile is stored or taken out, an auxiliary lift provided on both sides of the first floor entrance / exit space is moved up and down between the first floor and the second floor. First, an empty pallet is laterally fed from the auxiliary lift located on the first floor to the loading / unloading space on the first floor. At the same time, an empty pallet is placed on the auxiliary lift located on the second floor.
[0004]
Next, when the car enters the entry / exit space and is placed on the pallet, the pallet on which the car is placed is moved across the rail for the auxiliary lift located on the first floor, and this auxiliary lift is moved to the second floor. Raise to. At the same time, the auxiliary lift located on the second floor is lowered, and an empty pallet is laterally fed on the lateral feed rail into the storage / exit space. In this way, the two auxiliary lifts operate in parallel, and the entry and exit in the entry / exit space can be performed smoothly and smoothly only in two steps of traversing and raising / lowering.
[0005]
[Problems to be solved by the invention]
However, as shown in FIG. 8, the automobile mounted on the pallet on the lateral feed rail is equivalent to the height of the pallet 5 (for example, about 130 mm) and the height of the wheel 5a of the pallet 5 (for example, about 170 mm). It was only high (about 300mm). Thus, since there is a height difference of about 300 mm between the vehicle and the floor on which the vehicle gets on and off, when the driver gets off from the vehicle placed on the pallet 5, the boarding / alighting position (auxiliary lift position) I'm going down. On the other hand, when leaving a car, if there is a height difference of about 300 mm between the car and the boarding / exiting position (auxiliary lift position), the driver of the car will raise the foot from the floor to the car at a high position. As a result, it was difficult to get on and off the car.
[0006]
The present invention has been developed to solve such problems. That is, the object of the present invention is to reduce the difference in height between the car placed on the pallet and the position where the driver gets on and off, so that the driver can easily get on and off the car to be loaded or unloaded. The object is to provide a mold lifting type parking apparatus.
[0007]

Further, a limit switch 34 for detecting whether the lateral feed rail 12 is in the ascending position or the descending position is attached to an appropriate location of the elevating device 22. The limit switch 34 is provided with contacts 35 at two positions, an up position and a down position, and the contact mechanism 35 contacts the actuator 36 attached to the lateral feed rail 12 that moves up and down to raise the link mechanism 27. This is detected and the operation of the power cylinder 29 is stopped. Conversely, when the link mechanism 27 is lowered, the operation is detected and the operation of the power cylinder 29 is stopped. By providing the limit switch 34 in this manner, the lifting device 22 can be operated safely.
[0029]
7A, 7B, and 7C are explanatory views showing a state in which the position of the automobile is lowered by the lifting device. First, the pallet 5 (FIG. 7A) on the auxiliary lift 13 is transferred from the lateral feed rail 17 of the auxiliary lift 13 to the lateral feed rail 12 that is lifted by the lifting device 22. (FIG. 7B). Next, when the driver gets on and off the vehicle 6, the transverse feed rail 12 of the lifting device 22 is lowered by the height of the pallet 5 and the height of the wheel 5 a (FIG. 7C). Since the height difference from the position of the auxiliary lift 13 is reduced, the driver can easily get on and off the automobile 6.
[0030]
The present invention is not limited to the above-described embodiment, and the lifting device 22 has been described with respect to an embodiment in which the lateral feed rail 12 can be lifted and lowered by the link mechanism 27. Instead of this, the lateral feed rail 12 can be raised and lowered by a cam mechanism or a hydraulic cylinder or other lifting mechanism, and therefore various changes can be made without departing from the scope of the present invention. Of course.
[0031]
【The invention's effect】
