Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to an improvement of a three-tier multi-row parking facility that has upper, middle, and lower three tiers and a plurality of rows of parking spaces.

(Prior Art) The present applicant previously proposed the aforementioned three-stage multi-row parking facility in Publication of Utility Model Publication No. 55-4447. This parking facility is equipped with pallets that can be raised and lowered separately in the upper and lower parking spaces, and in the middle parking space, pallets are provided that are one less than the number of rows and can be moved horizontally. It forms the entrance and exit for the warehouse. Elevating and lowering drive mechanisms for the upper and lower pallets are separately provided at the rear of the upper parking space and at the rear of the middle parking space, that is, on the ground floor. In addition, each lifting drive mechanism supported a long rotating shaft with a length approximately equivalent to the width of the pallet, and a lifting chain that suspended the pallet was fixed to both left and right ends of the rotating shaft. Each lifting chain is wrapped around the sprocket, and an endless chain is stretched between the large sprocket fixed in the middle of the rotating shaft and the drive sprocket fixed to the end of the motor output shaft, and the rotating shaft is rotated by the drive of the motor. It is designed to raise and lower the upper pallet or the lower pallet.

(Problems to be solved by the invention) In the case of the above-mentioned parking facility, there are mainly four problems. The first problem is that because the lifting drive mechanisms for the upper and lower pallets are separated, on-site assembly and installation work, including adjusting their relative positions, is difficult, and maintenance and inspection work is a second-hand process. It is inconvenient. The second problem is that in order to span each lifting chain in the front and back direction, the aforementioned rotating shaft inevitably becomes a long and heavy object with a length approximately corresponding to the width of the pallet, and the support to support it becomes a heavy object. The structure becomes strong and large. The third problem is that the depth of the underground pit becomes longer than necessary because the counterweight attached to the lifting drive mechanism for the lower pallet installed on the ground floor is raised and lowered behind the lower parking space, and the excavation cost of the underground pit is increased. becomes higher. The fourth problem is that because the lower pallet lifting mechanism is installed on the ground floor, the lifting mechanism or its cover can be seen directly from the entrance, which is not aesthetically pleasing.

(Means for Solving Problems) The three-tier multi-row parking facility according to the present invention includes a drive part support body disposed at the rear of the upper parking space, and the drive part support body has a pair of vertical plates spaced apart from each other in the front and rear. Equipped with
Upper and lower elevating drive mechanisms for each row are placed together on the left and right between the two vertical plates, and two elevating drive mechanisms for the upper and lower stages are separated to the left and right from the two elevating drive mechanisms and guided downward. Each lower end of the lifting chain for the lower stage is attached to and suspended from the left and right rear ends of the upper and lower pallets, respectively, and the upper and lower pallets are supported by pivots on the left and right sides or the front and rear of the bottom, respectively, as appropriate. The two balance chains are spanned through several guide sprockets, and the front and rear ends of the upper balance chain are respectively attached to the upper fixed part in front of the upper parking space and the rear ground floor,
The front and rear ends of the lower balance chain are respectively attached to the lower surface of the front ground floor protrusion and the rear underground pit floor.

In addition, the upper pallet 8 and the lower pallet 9
As shown partially schematically in FIG. 5, the left and right, front and rear positions are controlled by engagement between the guide roller and the guide rail. That is, the upper pallet 8 has a guide roller 100 that is pivotally supported and protrudes upward to the left and right of the rear end surface and engages with a vertical guide rail 101 that is erected on the rear projection part 4b of the ground floor (the one on the right side

In use, when the vehicle W enters or leaves the upper pallet 8 or the lower pallet 9, if the middle pallet 10 is located in the middle parking space 3 of the desired parking row, the driving source 10b provided on the lower surface of the middle pallet 10 is driven. After moving the middle pallet 10 laterally, the motor 15a ₁ or 15b ₁ is driven to lower or raise the desired upper pallet 8 or lower pallet 9 so that the entry surface is aligned with the ground floor 4 (i.e., the upper surface of the U-shaped rail 11). ) and enter and exit the parking space in the middle parking space 3. After this loading/unloading, if the opening of the underground pit 5 is to be sealed for safety, it may be maintained as it is, or the motor 15 may be closed.
a ₁ or 15b ₁ is driven again and the upper pallet 8
Alternatively, the lower pallet 9 may be returned to its original raised or lowered position. Of course, if the desired pallet is the middle pallet 10, loading and unloading is carried out at that position, and the desired pallet is the upper/lower pallet 8.
or 9, if there is no middle pallet 10 from the beginning in the middle parking space 3 to be loaded or unloaded, it is sufficient to just move the desired pallet 8 or 9 up and down.

(Effects of the invention) As explained above, in the three-stage multi-row parking facility according to the invention, the box-shaped drive part support provided at the rear of the upper parking space is used for each parking row for the upper and lower parking spaces. Since the lifting drive mechanism is integrated on the left and right and built-in, assembly work including adjusting the relative position can be done at the factory before delivery to the site. Since the section supports can be transported separately for each parking row, on-site installation work can be shortened and simplified, and maintenance and inspection work can also be done at the same time for the upper and lower rows, making it easier. In addition, all of the lifting chains for the upper and lower stages are laid across in the left and right directions, so the driven rotating shaft can be extremely short and lightweight, and the front and rear width of the drive unit support can be minimized to the necessary minimum. and the depth of the building above ground is not increased unnecessarily due to this drive support. Furthermore, since the counterweight for the lower stage is also raised and lowered above ground, the depth space of the underground pit becomes smaller than before, and equipment costs such as excavation costs are accordingly reduced. Moreover, since the lifting drive mechanism and its cover are not directly visible from the storage entrance except for lifting and lowering the counterweight, it is aesthetically pleasing. Further, the drive part support body can be formed into a substantially sealed box by simply providing an opening in the lower surface for passing the lifting chain, so that it has a great soundproofing effect.
