Description

[Detailed Description of the Invention] The present invention relates to an improvement of a two-stage multi-row parking facility that facilitates entry and exit.

2. Description of the Related Art Conventionally, there have been two-stage, multi-row parking facilities constructed of steel structures, such as those shown in FIGS. 1 and 2, for example. This parking facility consists of a plurality of sets of pillars 1 and 1', one set of two front and rear pillars, erected on the ground at equal intervals, each with two upper and lower parking spaces 2,
The parking lot is divided into three parking rows. A vertical beam 4 and a horizontal beam 5 are installed between the upper ends of the front and rear columns 1, 1' and between the upper ends of the adjacent rear columns 1', 1', respectively. An entry/exit door 6 is formed in front of the lower parking space 3 of each parking row, and the lower parking space 3 is provided with a transverse pallet 7, one less than the number of parking rows. Front and back pillars 1, 1' on both sides
An elevating pallet 8 is provided so that it can be raised and lowered using the pallet 8 as a guide.

The lifting pallet 8 has one end of two lifting chains 9, 9' attached to the front left and right and rear left and right, respectively, and the chains 9 and 9' are pivotally supported on the vertical beam 4. It connects to the lower surface of the cross beam 5 through sprockets 10, 10', sprockets 12, 12 fixed to the rotating shaft 11 which is mounted between the upper ends of the rear columns 1', 1', and sprockets 14, 14' which are pivotally supported on the counterweight 13. It's worn.

15 is a large sprocket fixed to the rotating shaft 11, 16 is a forward/reverse motor with a reducer and a brake installed on the cross beam 5, and a motor is installed between the small sprocket 17 fixed to the end of the output shaft and the large sprocket 16. An endless chain 18 is wrapped around it.

The elevating pallet 8 can be moved up and down along the front and rear columns 1, 1' in a horizontal state by rotation of a rotating shaft 11 driven by a motor 16.

However, the parking facility configured as described above has two major problems. One of them is that since there are front pillars 1, 1 on both sides of each parking row, when entering the parking lot, the vehicle W must go straight ahead with the vehicle W facing straight in the front-rear direction. This parking operation will not be a problem if the road 19 facing the parking entrance 6 is wide, but if the road is narrow, the vehicle W may be moved forward and backward many times, and each time the steering wheel must be turned back and forth. This will significantly lengthen the warehousing operation time. The same can be said about the shipping operation.

Another problem is that the lifting chains 9, 9' hang down to the rear, and the counterweight 13 also moves up and down at the rear as the lifting pallet 8 moves up and down. In installation locations where there is a road in front and behind the parking facility, it may be convenient to use a so-called "pass-through system" in which an entrance and an exit are provided at the front and rear of the lower parking space 3, respectively. In such an installation example, when the vehicle W mounted on the traversing pallet 7 leaves the warehouse, the lifting chains 9, 9' and the counterweight 13 become a nuisance, making the leaving operation difficult.

In view of the above-mentioned circumstances, the present invention widens the distance between each set of pillars in the front and back so that two parking rows form one section, and forms entrances and exits at the front and rear of the lower parking space for each parking row. At the same time, in the lower parking space, one less than the total number of parking rows is provided with a horizontally movable transverse pallet, and all the elevating devices of the chain sprocket mechanism for the elevating pallet are arranged above.
The objective is to provide a two-tiered, multi-row parking facility for the purpose of facilitating entry/exit operations by allowing vehicles riding on an ascending/descending or traversing pallet in the lower position to pass through in the front and rear directions. .

Hereinafter, a detailed explanation will be given based on the embodiment shown in FIGS. 3 to 5. For convenience of explanation, the left and right in Figure 3 are referred to as "left" and "right," and the left and right in Figure 4 are referred to as "front."
It is called "after".

Reference numeral 20 is a two-stage multi-row parking facility, in which multiple sets of pillars 21 and 21' (two front and rear pillars) are erected on the ground floor F at equal intervals, and each parking row has two upper and lower parking spaces U and D. R1, R2, R3... are divided into two parking rows and one section. Front and rear cross beams 2 are provided between the upper ends of the front columns 21 and 21 and between the upper ends of the rear columns 21' and 21', respectively.
Furthermore, a plurality of vertical beams 23 are installed between the front and rear cross beams 22, 22' so as to divide the upper parking space U into each parking row. For each parking row, an entrance E and an exit E' are formed at the front and rear parts of the lower parking space D, respectively.

Reference numeral 24 denotes a transverse pallet arranged in the lower parking space D, one less than the number of parking rows, and a pair of front and rear rails 26, 26 with four wheels 25 pivotally supported at the four corners of the lower surface laid horizontally on the ground floor F. The driving source 27 installed on each of the pallets 24 allows the pallets to move horizontally.

Reference numeral 28 denotes an elevating pallet arranged in the upper parking space for each parking row, in which flanged guide rollers 29 and 29', which are pivotally supported and protrude from the front and rear ends of one side, are attached to the front and rear pillars 21 and 21', respectively. It is rotatably engaged with the inner protrusion and is movable up and down using the front and rear pillars 21, 21' as guides.

30 is a lifting device for the lifting pallet 28;
It consists of the following composition.

31 is a bearing 32 between the rear ends of the longitudinal beams 23, 23;
The rotating shaft is supported horizontally on the left and right by 32, and a set of two drive sprockets 33 on the left and right sides respectively.
33' is fixed, and a large sprocket 34 is fixed to the middle part.

35 is a reduction gear and a forward/reverse motor with a brake as a drive source installed on the rear cross beam 22', and an endless chain 37 is wound between the small sprocket 36 fixed to the end of the output shaft and the large sprocket 34. The rotary shaft 31 is rotated by driving the motor 35.

38, 38, 38', 38' are a pair of lifting chains on the left and right, each with one end fixed to the front left/right and rear left/right of the lifting pallet 28, and directly above these fixed points. The other end is fixed to the rear ends of a pair of left and right moving members 40 via support sprockets 39, 39' which are pivotally supported on the inner surface of the longitudinal beam 23 via appropriate brackets, and the drive sprockets 33, 33'.

41 is a chain for taking up the lifting chains 38, 38', one end of which is fixed to the front end of the moving member 40, and the other is connected via a guide sprocket 42 which is pivotally supported by an appropriate bracket on the front inner surface of the vertical beam 23. The end is connected to the lifting chain 38 between the support sprocket 39 and the drive sprocket 33 by a connecting member 43, and the movable member 40 is always held so as to be pulled forward and moved from the drive sprocket 33, 33'. The parts of the lifting chains 38, 38' facing the member 40 are taken over. Further, the distances between the drive sprockets 33, 33', the support sprockets 39, 39', and the guide sprocket 42 are sufficiently longer than the lifting distance of the lifting pallet 28, and the lifting pallet 28 is stopped at a predetermined position in the upper stage. At this time, the moving member 40 and the connecting member 43 are arranged so as to reach near the guide sprocket 42 and toward the rear.

In this way, the lifting chain is looped at the upper part so that there is no lifting device below the lifting pallet 28.

In addition, the transverse pallet 24 and the elevating pallet 28 are both formed to have a concave cross section so that the entire center area can be used for the vehicle W.
Parking areas 24a and 28a that also serve as guide passages,
The front and rear portions of the areas 24a and 28a are sloped downward so that the vehicle W can easily enter and exit the pallets 24 and 28. Furthermore, the left side of the areas 24a and 28a
On the right, front and rear, there are small protrusions 24b, 24c, 28 that the wheel _W1 can easily ride over.
b, 28c are provided protrudingly. This is when the driver gets into the pallets 24 and 28 when driving the vehicle W.
It is possible to stop the vehicle W at a predetermined position by sensing two slight impacts when W ₁ goes over the front protrusions 24b and 28b, and in the event that the vehicle W goes too far, the front wheel W ₁ Protrusions 24c, 28c
The function is to notify the driver that the vehicle did not stop at the specified position due to hitting the vehicle.

During use, as shown in Figures 3 and 4,
All the lifting pallets 28 are stopped at predetermined positions in the upper parking space U. In addition, the row pallet 24 includes each parking row R2, R3, except the rightmost parking row R1.
It has stopped. At this time, the entrances and exits E and E' of each parking row are completely open with no obstructions.

From this state, when warehousing each traversing pallet 24, the vehicle W enters the desired traversing pallet 24 from the front roadway P through the warehousing entrance E. For example, in the case of parking in the traversing pallet 24 of parking row R2, the vehicle W will move as shown by the lower double-dashed line arrow in FIG.
By moving forward from the right to the left and turning right when approaching the vicinity of parking row R2 and getting onto the traversing pallet 24, the driver can easily enter the parking lot without having to worry about looking at the front pillar 21.

In addition, when this vehicle W leaves the parking lot, it can be parked in line by turning right while moving forward and entering the rear lane P'.
Since there are no pillars or lifting chains between _R1 and _R2 , the unloading operation is extremely easy (as indicated by the two-dot chain arrow at the top of Figure 3).

Next, when entering and leaving the elevator pallet 8 in parking row R2, first the lateral pallet 2 in parking row R2
4 is traversed to the right and the elevator pallet 28 is lowered by the drive of the motor 35 of the parking row R2, and stopped when the pallet 28 touches the ground floor F. During this downward movement, the moving member 40
The connectors 43 and 43 are moved to the positions indicated by two-dot chain lines in FIG. 4, respectively.

The loading and unloading operations to and from the elevating pallet 28 are exactly the same as those for the transverse pallet 24 described above. However, during this loading/unloading process, the lifting chains 38, 38' extend vertically, but since these chains 38, 38' are located fairly centrally from the front and rear ends of the lifting pallet 28, loading/unloading is difficult. This does not cause any hindrance to the shipping operation. After loading and unloading,
The motor 35 is driven again to raise and return the lifting pallet 28 to its original position.

In addition, in the above-mentioned embodiment, the entrance E and the exit exit
E' is defined as the front and rear of the lower parking space D, but
This arrangement may be reversed, and furthermore, both the front and rear may be used as entrances and exits for both entering and exiting the warehouse, without specifically specifying them as entrances and exits.

In addition, in the state shown in FIG. 3, the lower parking space D, which is an empty space in the parking row R1, can be used as a temporary spare parking space during the night when the parking facility 20 is not in use.

As detailed above, when using the parking facility of the present invention, the distance between the pillars in the left and right directions is widened so that two parking rows are formed as one section, so it is possible to drive a vehicle diagonally even from a narrow road. You can enter the vehicle or drive diagonally. Therefore, the complicated operation of turning the handle as in the conventional case is avoided, making loading and unloading very easy, and the time required for loading and unloading is also greatly shortened. In addition, by housing the lifting device for the lifting pallet in the upper parking space, even when the lifting pallet is stopped at a predetermined position above, the chains of the lifting device will hang down to the front and rear of the lower parking space. Because of this, the so-called "pass-through method" is adopted, with the front and rear columns serving as entrances and exits, respectively. This method has many benefits, such as widening the scope of installation locations for parking equipment. .
