Description

Detailed Description of the Invention

[0001]

FIELD OF INDUSTRIAL APPLICABILITY The hydraulic pit of the present invention has two stages or three stages.
The parking system for multi-tiered vehicles has a pair of beams installed above the pit retaining walls on both sides of the pit, and the device is installed so that it is suspended from the beams. It's about doing.

[0002]

2. Description of the Related Art A conventional hydraulic pit type two-stage or three-stage parking device has a foundation on the bottom of the pit, and a pantograph or hydraulic cylinder is used to raise and lower a vehicle-mounted pallet, or four columns are erected from the foundation. The vehicle is stored by raising it, suspending the pallet from the top of the pillar, and moving the pallet up and down with a hydraulic cylinder via a chain or wire rope.

[0003]

[Problems to be Solved by the Invention] With the spread of passenger cars in recent years, the demand for cars has increased. The demand for mechanical parking equipment has increased due to the lack of parking space in cities and the fact that it cannot be filled on level ground and requires three-dimensional storage.
Mechanical parking equipment is expensive and is an obstacle to its widespread use, and there is a need for inexpensive equipment with good performance.

There is a demand for a safe and inexpensive mechanical parking device, and the present invention relates to a mechanism for safely and inexpensively storing a vehicle by omitting unnecessary objects.

[0005]

A conventional hydraulic pit type two-stage or three-stage parking device is provided with a base of a parking device at the bottom of the pit, and a pantograph or a direct-acting cylinder is provided on the base to provide a vehicle-mounted pallet. Hydraulic pressure,
A turret is erected on the foundation, and the vehicle-mounted pallet is hung by hydraulic pressure from the turret on a chain or chain. The hydraulic two-stage or three-stage parking device of the present invention suspends the pallet on which the vehicle is mounted. Instead of using a turret or a pantograph for lowering, a beam is passed over both walls of the pit, and a car-mounted pallet is hung from the beam by chains or wires.

Whereas the conventional device supports the total weight of the four pillars on the foundation, the device of the present invention supports the total weight of the pallet on the upper four places of the pit retaining wall, as well as on the bottom of the foundation. To attach the beam to the upper surface of the retaining wall, tighten the anchor bolts firmly to the upper and side surfaces of the retaining wall.

The pallet is suspended by wire ropes or chains from four end portions of a pair of beams attached to the upper surface of the pit retaining wall, and the wire ropes or chains are attached by hydraulic cylinders attached to the lower surface of the beam portions. Is pulled,
The two beams are pulled up from the four end points. By moving the cylinder back and forth, the pallet can be moved up and down to store the car in the pit. Since the pallet for vehicle mounting is suspended by wire ropes or chains from both ends of the beams on both sides, that is, four points, the pallet can be stowed up and down in a stable and strong manner even against rolling and pitching.
Furthermore, in the state of hoisting to the highest point, the hanging position is close to the wire rope or chain mounting position and the anchor bolt mounting position on the upper part of the beam pit retaining wall, so the vertical pallet is stable against rolling and pitching. And has the effect of being fixed.

[0008]

[Operation] Hydraulic pit 2 constructed as above
The multi-tiered or three-tiered parking system is weak and unstable against roll and pitch because the conventional system is mounted on a pantograph, a hydraulic cylinder or a turret rather than on the base of the bottom, but the system of the present invention is a pit. Since it is fixed to the upper surface of the retaining wall and the inner surface of the retaining wall with anchor bolts, there is no swaying due to deformation of columns or pantographs, so it is possible to mount stably against horizontal swaying and vertical swaying.

A pair of beams passed between the retaining walls serve as support pillars for the retaining walls on both sides, and the earth pressure on the retaining walls impairs the role of reinforcing beams to prevent the collapse of the retaining walls inside the pit. You can

Since the foundation of the conventional device is provided at the bottom of the pit, it is necessary to reinforce the foundation by hitting the foundation pit or inserting a split chest in a place where the bearing capacity is small.
Since the device of the present invention is mounted on the upper part of the pit retaining wall, the total load becomes a distributed load on the entire lower face of the retaining wall, and there is no need for special foundation work for mounting the device in the pit as in the conventional device, thus reducing the construction cost. Become.

Since the device of the present invention does not require a column for supporting the beam portion, the amount of saving of the column and the pantograph is large, and it is not necessary to perform leveling, installation, and the like. The pit-type 3-tier (pit depth 3,550 mm) is higher than the pit-tier 3 tier (pit depth 1,850 mm), and therefore has many pillars, resulting in even greater savings.

[0015]

Since the present invention is constructed as described above, it has the following effects.

In the parking device to the upper part of the pit retaining wall, the load spreads to the lower part of the retaining wall and becomes a distributed load, so that no special foundation or foundation pit is needed.

When the frontage of the pit is wide, the beam of the present invention serves as a supporting beam to withstand the earth pressure applied to the retaining wall, and the reinforcing effect can be obtained.

Since the turret and pantograph are not used, the structural material for supporting the pallet is saved, and furthermore, because it is fixed to the pit upper surface with anchor bolts at the top of the stowage, it can be rolled or pitched. Is more stable than conventional devices.

Since it is not necessary to lift up from the foundation of the bottom of the pit, installation workability is good, and local construction costs can be saved.

In the conventional hydraulic system, since a beam has a supporting column, it is not possible to provide a long cylinder under the beam, and a double cylinder or a double wire is required. Therefore, the cost is high. The length is around 5m,
Since the depth of the three steps of the pit is about 3.6 m, the structure can be simplified because the single-acting cylinder stroke can move up and down inside or under the beam.

According to the present invention, since the wire rope or the chain does not pass through the bottom of the pit but through the beam and the upper portion of the retaining wall, the length is short, the length is short and the cost is reduced as compared with the prior art, and the carry-in installation is easy. .

In the pantograph type (Fig. 9) and the cylinder mast type (Fig. 10), it is difficult to synchronize the left and right hydraulic cylinders, and the accuracy of the deco valve (shunt / collector valve) makes it difficult to synchronize when the winter is cold and causes the meandering. However, since the present invention has only one hydraulic cylinder, it does not meander and the pallet does not tilt.

In most cases, the pit-type parking device is used in parallel in a multi-story building. In this case, both side devices are interlocked and only one device is used for safety standards. Therefore, it is not necessary to provide a hydraulic unit for driving each device, and it is possible to operate several units (generally one unit for 4 to 5 units by connecting hydraulic pipes, one unit for each unit). This is more rational and cost saving than the electric motor open type with a lifting drive mechanism.
