Description

[Detailed Description of the Invention] <Industrial Field of Application> This invention relates to a two-stage parking device in which upper and lower pallets are both arranged in an inclined state.

<Conventional technology> As a conventional parking device of this type,
There is one described in Publication No. 35511. The parking device is
Install the hydraulic cylinder of the push-up mechanism on the pit floor,
The rod end of this hydraulic cylinder is connected to the lower pallet, and the upper and lower pallets are raised and lowered by the expansion and contraction of this hydraulic cylinder.

<Problems to be solved by the invention> In the conventional two-stage parking system described above, when the pallet is held in the raised position, oil leaks from the cylinder packing of the hydraulic cylinder that holds the pallet. There is a problem that the pallet becomes lower due to this.

There is also the problem that this leaked oil stains the pit floor.

The object of this invention is to provide a two-stage parking device that does not use a hydraulic cylinder and does not allow the pallet to lower even when the pallet is held in a raised position.

<Means for solving the problem> The two-stage parking device of this invention has front columns on both sides of the vehicle entrance and exit of the parking space, rear columns on both sides of the back of the parking space, and the front and rear columns are connected. A main body including first beams connected in the front and rear on both sides corresponding to the vehicle entry height and second beams connecting the rear supports, each of which has a width corresponding to the floor area of the parking space. An upper shelf for parking, which is vertically spaced substantially parallel to each other, each front end side of which is rotatable up and down, the rear end of which is pivotally supported on the rear support side of the main body, and both sides of which are linked to each other by link members. and a lower pallet, and respective front parts are provided so as to support positions on both sides of the lower pallet close to the front column near the upper part of the front column of the main body, and each rear part is guided toward the column side. and a pair of strips on both sides, which are provided so that when the rear part of the pallet is pulled toward the rear column, both pallets rise, and when the traction is returned, both pallets are lowered by their own weight; A strip drive wheel that engages with each rear part of the strip and is provided on a common synchronized shaft, and the synchronized shaft is rotatable in either forward or reverse direction. It is characterized by comprising a rotation drive unit that can maintain the state.

The front portion of the strip is provided near the upper part of the front column to support the lower pallet, but the guide wheel of the strip may be provided so as to function as a movable pulley.

It is preferable that the rotational drive section is composed of a geared motor with a brake or a motor with a brake and a speed reducer using a worm and a worm wheel with a large reduction ratio.

<Operation> According to the above means, by operating the motor, the synchronized shaft can be rotated, and the rear portions of both strips engaged with the drive wheels can be pulled or returned to their original positions. When the upper and lower pallets are in a lowered state and the strip is pulled toward the rear column by operating the rotary drive unit, the lower pallet is lifted, and accordingly, the upper pallet is also lifted via the link member. In this pallet raised state, even if there is a vehicle on top of the pallet, the rotary drive section remains in a stopped state. When the traction state is restored to its original state, the upper and lower pallets return to their original lowered state. This two-stage parking system is used by being installed in a pit so that a car can drive onto the upper pallet when the pallet is in a lowered state, and onto the lower pallet when it is raised.

<Example> A first example will be described using FIGS. 1 to 3. In the figure, 1 is the main body, 2 is the upper pallet,
3 is a lower pallet, 4 and 5 are strips, 6 and 7 are strip drive wheels, and 8 is a rotational drive section.

and other suitable reinforcing parts 17, 18, etc.

The upper pallet 2 and the lower pallet 3 each have an upper surface corresponding to the floor area of the parking space, and the upper pallet 2 is formed slightly longer in the front-rear direction. Both pallets 2 and 3 have their rear ends pivoted to rear struts 12 and 13 via pivots 19 and 20, so that their front sides (left side in the figure) can rotate up and down. 21 is a link member, pallet 2,
Both pallets 2 and 3 are linked together, so that when one pallet is moved up and down, both pallets 2 and 3 remain substantially parallel and move together. The gap between the pallets 2, 3 is larger than the height dimension of the vehicle.

The strips 4 and 5 are formed of roller chains that engage with sprockets, and are provided so as to support the main body 1 on both sides of the front portion of the lower pallet 3. As shown in FIGS. 2 and 3, the front ends of the strips 4 and 5 are connected to both sides of the front part of the lower pallet 3 in the lowered state, and extend upward, respectively, to the front strut 1.
The front strut 1 is wound around a guide ring 22 provided inside each of the upper ends of the
It is wound around a guide ring 23 provided on the inside of the lower part of the numbers 0 and 11 and extends rearward. The rear parts of the struts 4 and 5 are wound around guide wheels 24 provided at the lower ends of the rear struts 12 and 13, respectively, and extend upward.
It is wound around the strip drive wheels 6, 7 provided on the upper part of the wheels 2, 13, and terminates downward. The strip drive wheels 6, 7 are fixed to one synchronized shaft 24 supported across the rear struts 12, 13, and always rotate by the same amount. The guide wheels 22, 23, 2
4. The strip drive wheels 6 and 7 are formed of sprockets.

The rotational drive section 8 is composed of a geared motor with a brake, and is installed on the second beam 16, so that the tuned shaft 24 can be rotated in both forward and reverse directions through a sprocket and a chain. 2 in the diagram
5 is an operation panel, 26 is a pit, and 27 is a fence.

In this two-level parking device, when the upper pallet 2 and the lower pallet 3 are raised in the state shown in FIG. . Further, as shown in FIG. 2, when the upper pallet 2 and the lower pallet 3 are lowered, the front end of the upper pallet 2 is in line with the vehicle entry surface 26, and in this state a vehicle can be taken in and out of the upper pallet 2. In the ascending state shown in Fig. 1, when both pallets 2 and 3 contain vehicles, their weight is equal to that of the strips 4 and 5.
The geared motor with a brake, which is stationary, does not rotate even if an attempt is made to rotate the output shaft, so the pallets 2 and 3 will not descend. do not have.

A second embodiment will be explained using FIGS. 4 and 5. This embodiment differs from the first embodiment only in the tensioning state of the strips 4 and 5, and since the strips 4 and 5 are provided symmetrically on both sides, only one strip 5 will be explained. .

The tip of the strip 5 is fixed to a protrusion 30 provided inside the front side of the portion of the first beam 15 connected to the front support 11, and the portion following this extends downward and is provided on the side surface of the lower pallet 3. It is wound around a first guide ring 31 provided on the inside of the upper end of the first beam 15 and extends upward, and is further wound around a second guide ring 32 provided inside the upper end of the first beam 15 and extended downward, and is placed inside the lower part of the front support 11. It is wrapped around the provided third guide ring 33 and extends rearward. The other structure is the same as that of the first embodiment.

In this embodiment, since the first guide wheel 31 is provided on the lower pallet 3, when the strip 5 is pulled rearward, the first guide wheel 31 also rises together with the lower pallet 3, so that it functions as a movable pulley. Therefore, the traction force may be 1/2 that of the first embodiment.

A third embodiment will be explained using FIGS. 6 and 7. This embodiment differs from the first embodiment only in the tensioned state of the front parts of the strips 4 and 5, and since they are provided symmetrically on both sides of the strips 4 and 5, one strip I will explain about it.

The tip of the strip 5 is fixed to a protrusion 40 provided to protrude laterally from the lower surface of the lower pallet 3, and the part following this extends upward to form a first guide provided inside the first beam 15. It is wrapped around a ring 41 and extends downward, then wrapped around a second guide ring 42 provided inside the lower part of the front strut 11 and extended upward, and further, a third guide ring provided inside the first beam 15 It is wrapped around a guide ring 43 and extends downward, and is wrapped around a fourth guide ring 44 provided inside the lower part of the front strut 11 and extended rearward. The other structure is the same as that of the first embodiment.

In this embodiment, the traction force of the strips 4 and 5 can be 1/3 that of the first embodiment.

In the above embodiment, the rotary drive unit 8 is connected to the rear support 1.
2 and 13, but in some cases, it may be provided together with the tuning shaft 24 at the lower position of the rear struts 12 and 13.

<Effects of the invention> According to this invention, since a hydraulic cylinder is not used in the rotary drive unit for driving the pallet up and down, there is no oil leakage and the stopped state can be maintained without reversing due to load. Therefore, the parking pallet does not naturally descend. Therefore, the pallet can be held in place reliably and the inside of the pit will not become dirty.

In addition, when multiple two-stage parking devices are installed in a row, the front column, rear column, and first beam can be shared between adjacent parking devices, so those on one side can be omitted and the material Expenses and costs can be reduced.
