Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a multilevel parking system that includes a plurality of parking spaces and a lift cage.

[Conventional technology]

Conventionally, in urban areas, it has been difficult to secure a large, flat parking space, so parking systems have been developed that secure a parking space in a part of a building and use an elevator to accommodate vehicles in this parking space. In addition, various types of large-scale multilevel parking systems that can accommodate a large number of vehicles per level area have been proposed, such as a multi-row, multi-level, up-and-down, traversal type parking system known as a so-called puzzle parking system.

However, with conventional parking devices that secure a parking space in a part of a building, the vehicle is driven by itself into an elevator cage, and the elevator is moved up and down to a floor where a designated parking space is provided. Next, the vehicle is driven by itself and stored in an empty space, and the vehicle is driven by itself to get on and off the elevator and move in the parking space.
There are safety issues during LFJ and transportation, and the complexity of having the vehicle run by the driver.

In addition, in a horizontal elevating parking device with one stage, 2 m rows, and n columns, a pallet on which the vehicle is mounted is provided on the elevating cage, the vehicle is placed on this pallet, and the elevating cage is moved up and down except for the top row. !-1) Utilizing the empty space in each row in the hall, raise the pallet to any i row and stop it, then pull out the pallet carrying the vehicle from the elevator cage with the retracting device, and move it to the desired j row with the traversing device. , and store them in rows.
In addition to requiring a large number of pallets on which vehicles are mounted, the structure of the elevator cage itself becomes complicated, and the retracting device also becomes complicated, increasing the cost of the entire parking device.

Therefore, the inventor of the present invention aimed to provide a safe and inexpensive multilevel parking system by simplifying the structure of the lift cage. Traversable trolleys are installed in each row of each row except the lower row, and a lift cage is suspended above the parking space at the top of each row so that it can be raised and lowered. It is formed in a U-shape with an upper frame and left and right frames that face each other on the sides, and a support arm that supports the vehicle body between the wheels of the vehicle is movably attached to the lower ends of the left and right frames. A multi-story parking device (Japanese Patent Application No. 1983-73657) characterized in that the arm is configured to be movable by a movable mechanism between a storage position along the left and right frames and a support position supporting the vehicle body. is suggesting.

In the above invention, by stopping the vehicle at the landing position of the elevator cage, the support arm of the elevator cage is moved from the stored position where it does not contact the vehicle, and the support arm supports the vehicle body between the wheel bases of the vehicle. By raising the elevating cage in this state, the vehicle is raised to an arbitrary stage i while directly supporting the vehicle body, and a transverse bogie on which any vehicle can be mounted is positioned below the elevating cage, and the vehicle is lifted onto the transverse bogie. The vehicle will be delivered to the customer.

[Problems to be Solved by the Invention] However, the wheelbases and widths of parked vehicles differ depending on the type of vehicle, and various devices are installed at the bottom of the vehicle body. Even if you try to support it, interference may occur and it may not be possible to support it properly.

This invention solves the above-mentioned problems in multi-level parking systems, and provides a safe and inexpensive multi-level parking system that can securely support vehicles regardless of the type of vehicle, does not require pallets. The purpose is to

[Means for solving problems]

In order to solve the above-mentioned problems, the multi-story parking device of the present invention has two holders on each of the left and right lower beams of a box-shaped elevator cage with open front and rear opposite sides of the lower bottom in the front and rear directions. The holder is movably provided, and the holder frame is provided with one or two holders each having a patterned claw, each of which is rotatable about a fir axis.

[Operation] In the case of warehousing, the vehicle enters the warehousing position and stops, and after the driver exits the vehicle, the lift cage is lowered to that position with the holder parallel to the lower beam. Once the elevator cage has landed on the floor, move the front and rear holders until they are approximately in the center of the front and rear tires. When the holder base is centered on the tire, rotate the holder and use its claws to hold the tire. In this state, the lift cage is raised to a desired parking step, and an empty trolley is placed under the lift cage. The elevator cage is lowered onto the trolley, and the holder is rotated to return it to a state parallel to the lower beam, and the vehicle is transferred onto the trolley. There, the cage is rolled up, and the trolley carrying the vehicle is moved across and stored in the parking position. For shipping, follow the steps in reverse.

〔Example〕

The present invention will be described in detail with reference to the drawings.

1 to 6 are diagrams showing one embodiment of the present invention. FIG. 1 is a perspective view of a framework of a lifting cage that can be raised and lowered,
The elevator cage 1 includes a rectangular frame 2 forming an upper surface, a vertical frame 3 extending downward from the four corners of the rectangular frame 2 to form a side surface, and bridges between the lower ends of the front and rear vertical frames 3 to form a lower bottom. A main frame is formed by the formed lower beam 4.

The rectangular frame 2 is provided with guide members 5 at the front and rear ends,
It engages with a guide rail 6 that is fixed and extends in the vertical direction. A wire rope 7 is attached to the center of the rectangular frame 2, and by winding this up and unwinding it with a hoist (not shown), the elevator cage 1 can be raised and lowered.

Two holders 8 are respectively provided on the left and right lower beams 4 of the elevator cage 1 so as to be movable in the front and rear directions.

FIG. 2 is a cross-sectional view of the lower beam 4, FIG. 3 is an explanatory diagram of the holder frame, and FIG. 4 is a perspective view of the holder.

Here, the lower beam 4 is a beam having a U-shaped cross section and opens inside the elevator cage 1, and a holder frame 8 is slidably attached to the lower beam 4. Upper and lower surfaces 8 of the holder frame 8
A female threaded hole 10 is provided in the support 9 that connects a and 8b, and a moving screw 11 attached to the lower beam 4 is screwed into this female threaded hole 10.
1 by a moving motor 12, the holder frame 8 moves back and forth. A holder 14 equipped with a wedge-shaped claw 13 is pivotally attached to this holder pedestal 8 so as to be rotatable about a vertical shaft 15, and one end of a rotating arm 16 is pivotally attached to this holder 14. has been done. The lower beam 4 is provided with a common spline shaft 17 and a rotation motor 18 for simultaneously rotating the holders 14 of the front and rear holder frames 8.
A sleeve 18 having a spline hole on the inside and a screw on the outer periphery is attached to the spline shaft 17. This sleeve 18 is supported by bearings 19 at both ends fixed on the holder frame 8, and a slider 20 is screwed onto the outer periphery of the sleeve 18. The other end is pivoted. Therefore, the sleeve 18 moves back and forth as the holder frame 8 moves, and is rotated by the rotation of the spline shaft 17, causing the slider 20 thereon to move back and forth. Here the front and rear sleeves 18
Since the screws are oppositely threaded, the front and rear holders 14 rotate in opposite directions so that the claws 13 close or open each other.

The holder frame 8 is provided with an obstacle detector 21 .

As shown in FIG. 5, transverse rails 24 are laid at each stage on both sides of the passage through which the elevator cage 1 ascends and descends.
A truck 25 is arranged on these traversing rails 24. The lateral movement of this truck 25 is controlled by a drive means (not shown).

Next, the operation will be explained. Normally, the lifting cage 1 has a holder 14
is above the parking position of the vehicle in a state parallel to the lower beam 4, and after the vehicle 26 is stopped at the parking position in this state and the driver gets off, the elevator cage 1 is lowered. Once the elevator cage has landed on the floor, the drive motor 1 is turned on as shown in Figure 6 (a).
2, the screw 11 is turned to move the front and rear holders 8 toward the center of the tire 27, respectively. When the holder frame 8 comes to the center of the tire 27, the obstacle detector 21 detects the tire 27 and stops the holder frame 8. Next, the spline shaft 17 is rotated by the rotation motor 18, the holder 14 is rotated toward the closing side, and the tire 27 is held by the claws 13 as shown in FIG. 6(b).

Once the vehicle 26 is held, the lift cage 1 is raised to a position slightly above a desired vacant parking step, and the empty trolley 25 is moved under the lift cage 1. Then, lift cage 1
is lowered to land on the trolley 25, and the holder 14 is rotated to the open side. When the holder 14 is released, the vehicle 15 is moved onto the trolley 25, so that the elevator cage 1 is raised. The trolley 25 on which the vehicle 26 is placed is moved sideways to a parking position and stored. Carry out the retrieval process in the reverse order as above.

〔Effect of the invention〕

As described above, according to the present invention, there is no need for a pallet for mounting the vehicle, the lifting cage can securely hold the vehicle regardless of the vehicle type, and the hoisting device enables high-speed operation. . Furthermore, since the holder frame can be installed in a narrow space, the dimensions of the elevator cage can be reduced.
