Description

Detailed Description of the Invention (Industrial Application Field) The present invention provides a plurality of vehicle loading pallets that circulate and store vehicles in a parking space on a floor or underground. A hoistway is provided between a vehicle entrance space facing the entrance and exit and a side of the parking space, and an elevating lift is provided that moves up and down within the hoistway to transport pallets. Regarding mechanical parking equipment.

(Prior Art) The present applicant previously disclosed the above-mentioned mechanical parking equipment in Japanese Patent Application Laid-Open No. 160477/1983. In this mechanical parking equipment, two pillars for vertically guiding the lift up and down are spaced apart in the longitudinal direction of the lift and are erected with their lower ends fixed to the floor of the hoistway.
The upper end of each column is fixed to the ground floor above the hoistway by appropriate brackets. The vertical lift is supported in a cantilevered manner by having support rollers supported above and below the vertical portion rotatably engaged with the recesses in the side surfaces of each of the pillars.

(Problems to be Solved by the Invention) However, the above-mentioned mechanical parking equipment has the following two problems. First of all, the first problem is that there is no anti-vibration means at the parts where each pillar is fixed to the fixed part of the parking equipment (i.e. the floor of the hoistway and the ground floor above the hoistway), so This occurs from various parts of the lifting lift and the pallet mounted on the lifting lift, such as contact between the pallet and the lifting lift when the pallet is moved onto the lifting lift, and rolling contact of the support rollers on the pillars when the lifting lift goes up and down. The vibrations propagate to the building through the pillars, and the buildings adjacent to the parking facilities are also adversely affected by vibration and noise.

The second problem is that since the two pillars span the entire length of the hoistway, they are very long and slender compared to the cross section of the pillars, and are erected independently, with only the upper and lower ends of the building being exposed. Fixed on the side. Furthermore, as mentioned above, the lifting lift is cantilever-supported by the two pillars, and the center of gravity of the entire lifting lift, including the vehicle and pallet, is far eccentric from the center of both columns, so the load of the lifting lift, etc. This will act as a compressive force on the column, increasing the bending moment, and there is a risk that both columns will not be able to withstand the long-term loads associated with normal operation.

The present invention has been made in view of these points, and its purpose is to effectively increase the rigidity of each of the above-mentioned columns, and to provide vibration isolation means to the support points of each column to improve strength and prevent vibration. The purpose is to provide mechanical parking equipment with excellent lift.

(Means for Solving the Problems) In order to achieve the above object, the solving means of the present invention is a mechanical parking facility that is equipped with a plurality of vehicle-mounted vehicles that circulate and store vehicles in a parking space downstairs or underground. A pallet is provided, an entrance is provided on the floor or on the ground, a hoistway is formed between the vehicle entry space facing the entrance and the side of the parking space, and It is assumed that an elevating lift is provided for elevating and lowering the pallets to transport the pallets. A plurality of pillars for guiding the lifting/lowering lift are erected on the floor of the hoistway at distances in the longitudinal direction of the lifting lift, and vibration isolation is provided between the lower end of each pillar and the floor of the hoistway. material is interposed. Further, each of the columns is connected to each other by a joint beam, and a mounting member that protrudes laterally is provided at an appropriate position on each of the columns, and the tip of the mounting member is attached to a bracket fixed to the wall of the hoistway for vibration protection. The structure is such that they are connected via a material.

(Function) With the above configuration, the plurality of columns erected on the floor of the hoistway are connected to each other by connecting beams, and the columns are attached to the hoistway through the mounting members and brackets at appropriate locations. Since it is also connected and supported by the walls, their rigidity is effectively increased. For this reason, the center of gravity of the entire lifting lift including the vehicle and vehicle-mounted pallet acts with a large eccentricity from the center of each column, and these pillars are able to sufficiently withstand even when a large bending moment is applied.

In addition, since vibration isolating materials are interposed between the lower end of each pillar, which is the support point, and the floor of the hoistway, and between the mounting member and the bracket, the lifting lift and the Even if vibrations generated from various parts of the pallet are transmitted to the columns, they are hardly transmitted from the columns to the building (the floors and walls of the hoistway).

In addition, two pillars 100, 100 of the support structure 25 supporting the lifting lift 24
, the weight of the lifting lift 24, pallet 4, and the entire vehicle A acts as a moment load, but each column 100 simply has its lower end connected to the hoistway 1.
In addition to being supported on the floor 18a of 8, they are also connected to each other by joint beams 101 at two locations, an upper portion and an intermediate portion, and a mounting member 102 and a fixing member 104 at each of the two locations. and the wall 18b of the hoistway 18 via the bracket 103.
Since the pillars 100 are connected and supported by the pillars 100 and have significantly increased rigidity, they can sufficiently withstand the moment load.

Thereafter, the movable auxiliary floor 34 protrudes to the right and closes the right side of the rectangular hole 19a. Next, the reversible motor 32 is driven to move the rotating frame 31, pallet 4, and vehicle W in the clockwise direction in FIG.
Rotate 90° (double-dashed line in Figure 2). This results in
The vehicle W is turned around by 90 degrees, and the front part faces the entrance/exit 21 (double-dashed line in FIG. 1). and,
The movable deck 23 swings horizontally, and is flush with and connected to the vehicle entry surface of the pallet 4 via the movable deck 23 with the entry floor 22 of the entrance 21. After that, the driver opens the opening/closing door 21a and
1, enters the vehicle entry room 20, enters the vehicle W through the ground floor 19 and floor 33, and exits to the outside through the entry/exit entrance 21 by forward driving.

Thereafter, the empty pallet 4 that has been taken out of the parking lot is returned to the parking device 1 by the reverse sequential operation. That is, the rotating frame 31 rotates 90 degrees counterclockwise from the state shown by the two-dot chain line in FIG. Arm 15
The lifting lift 24 returns to its original lowest position (the position indicated by the dashed line in FIG. 1).

When entering the warehouse, the vehicle W enters the pallet 4 by driving forward from the entry/exit entrance 21 in the state shown by the two-dot chain line in FIG. It may be accommodated in the parking device 1 in the same manner as in the operation.

It should be noted that the present invention is not limited to the above embodiments, but includes various other modifications. For example, in the embodiment described above, the mounting member 102 is fixed to the junction of the column 100 and the joint beam 101, but in the present invention, the mounting member 102 is fixed to the joint beam 101 at a position slightly away from the column 100. or
Alternatively, it may be fixed only to the pillar 100 at a location other than the merging portion.

In addition, in the above embodiment, a case was explained in which a "multilayer circular circulation" type parking device 1 was used, but the present invention also uses a "multilayer box circulation" type, a "horizontal circulation" type, etc. Of course, it can be applied in the same way also when using.

Further, in the embodiment described above, the fixing means 1 is used to connect the mounting member 102 provided on the column 102 and the bracket 103 fixed to the wall 18b of the hoistway 18.
04, and the fixing means 104 has a structure in which a rubber bushing 104c as a vibration isolating material is filled between the inner cylinder 104b and the outer cylinder 104d.
It is not limited to 04. The point is that a vibration isolating material should be interposed between the mounting member 102 and the bracket 103 to connect them.

(Effects of the Invention) As explained above, according to the mechanical parking equipment of the present invention, a plurality of pillars that guide the lifting and lowering of the lift are interconnected by connecting beams, and each pillar is attached at appropriate locations. It is connected and supported to the wall of the hoistway via a member and a bracket, and a vibration isolating material is interposed between the lower end of each pillar and the floor of the hoistway, and between the mounting member and the bracket. As a result, the rigidity of each column can be effectively increased, and the vibration generated from each part of the lifting lift and the pallet mounted on the lifting lift can be suppressed from being propagated to the building through the pillars, increasing the strength. It also has a great effect on vibration isolation.
