The present invention has been made in view of the above problems, and an object of the present invention is to provide an ascending / descending transport device of a multi-story parking facility capable of obtaining a large ascending / descending transport stroke without disposing a large and heavy driving device at an upper portion. And
[0008]
[Means for solving the problem]
In order to achieve the above object, the lift transport device of the multi-story parking facility of the present invention raises and lowers a cage supporting a vehicle along a row of parking spaces arranged in multiple stages by a lifting mechanism, and enters a vehicle into the parking space. In the elevating and lowering transport device of the multi-story parking facility for carrying out the retrieval, the elevating mechanism is configured such that the supporting cable connected to the cage is inverted downward via a supporting inverting pulley member disposed above the elevating area of the cage. A movable pulley member of a parallel groove disposed movably up and down to the side of the elevating area of the cage, and a fixed pulley member of the parallel groove fixedly disposed above the movable pulley member. And the other end is fixed, and a drive system pulley mechanism comprising lifting drive means for moving the movable pulley member toward and away from the fixed pulley member to raise and lower the cage, and the tip is fixed.

[0009]
With this configuration, the main part of the lifting mechanism is located on the side of the lifting area of the cage, and the driving system pulley mechanism is a multi-stage moving pulley because the moving pulley member is a multistage moving pulley, so that the cage can be enlarged with a small stroke of the lifting drive means. On the other hand, in the balance system pulley mechanism, the moving amount of the counterweight member is larger than that of the moving pulley member because the moving weight pulley member is a multi-stage moving pulley, and as a result, the weight of the cage is balanced by the light counterweight member. Become
[0010]
Further, the lifting drive means is a hydraulic cylinder device.
[0011]
Thereby, a small and large driving force can be obtained.

[0016]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a conceptual perspective view of a lifting and lowering transport device of a multi-story parking facility according to the present invention, and FIG.
[0017]
The elevator transport device 10 of the multi-story parking facility shown in FIGS. 1 and 2 supports a cage 11 that supports a vehicle via a pallet (not shown) horizontally by an elevator mechanism 20 and a balance mechanism 30 as a balance device. The mechanism 20 is moved up and down in an elevating space adjacent to an arrangement area of storage shelves (not shown) arranged in upper and lower tiers.
[0018]
The cage 11 has a rectangular frame shape (partially omitted in FIG. 1) in plan view, and has two hanging wires as supporting ropes of the lifting mechanism 20 at two corners located at opposite corners thereof. 21 are connected via the bracket 11A, and two weight ropes 31 of the balance mechanism 30 are connected to the other two corners via the bracket 11A, respectively. 31 and is suspended and supported. The other end of the suspension wire 21 is fixed to the building side (the axis of the fixed sheave 22C in FIG. 1), and the other end of the weight rope 31 is connected to the balance weight 33.
[0019]
The lifting mechanism 20 includes a drive system pulley mechanism 22 and a balance system pulley mechanism 23.
[0020]
In the drive system pulley mechanism 22, each hanging wire 21 supporting the cage 11 is wound around an upper sheave 22A as a support reverse pulley member, a movable sheave 22B as a movable pulley member, and a fixed sheave 22C as a fixed pulley member. And a hydraulic cylinder 22D as a lifting drive means for driving the movable sheave 22B up and down.
[0021]
The upper sheave 22A is disposed at a position corresponding to a corner of the cage 11 above the elevating area of the cage 11 with the rotation axis being horizontal, and turns the direction of the suspended suspension wire 21 horizontally or downward. It has become.
[0022]
The movable sheave 22B is provided on a movable base 22E that can be moved up and down within a predetermined range with its rotation axis being horizontal, beside the elevating area of the cage 11. The movable base 22E is provided with a connection beam 22G via a support cable 22F, and the cylinder rod of the hydraulic cylinder 22D is connected to the connection beam 22G.
[0023]
The fixed sheave 22C is fixedly installed on the building side above the elevating area of the movable sheave 22B with its rotation axis parallel to the movable sheave 22B.
[0024]
The movable sheave 22B and the fixed sheave 22C are formed in a plurality of parallel grooves in which a plurality of sheaves are arranged in the axial direction. The suspending wire 21 is wound around the lower side of the movable sheave 22B to be turned upward from below, and further wound around the upper side of the fixed sheave 22C to be turned upward from below, and is repeated so as to be repeated by the number of grooves. Have been laid out.
[0025]
The hydraulic cylinder 22D has a main body vertically fixedly installed on the building side, and is driven by hydraulic pressure from a hydraulic unit 27 including a hydraulic pressure generating device and a control device.
[0026]
The drive system pulley mechanism 22 configured as described above drives the movable sheave 22B up and down via the connecting beam 22G by the hydraulic cylinder 22D, thereby changing the position of the movable sheave 22B with respect to the fixed sheave 22C and changing the position thereof. The suspended cage 11 is moved up and down through 21.
[0027]
Since the suspension wire 21 is wound around the movable sheave 22B, the movable sheave 22B is a so-called moving pulley, and the moving amount of the cage 11 is such that one turn of the suspension rope 21 around the movable sheave 22B. As two, the number of movements of the movable sheave 22B is several times the number of movements. That is, if the number of turns of the hanging wire 21 around the movable sheave 22B is two, the number of strips is four, and the cage 11 moves four times as much as the movable sheave 22B. Therefore, by appropriately setting the number of turns of the movable sheave 22B and the fixed sheave 22C, the cage 11 can be raised and lowered greatly by the hydraulic cylinder 22D having a small stroke. For example, if the number of turns of the hanging wire 21 around the movable sheave 22B is 7 as in the example of FIG. 1, the number of strips is 14, and the cage 11 moves 14 times the moving amount of the movable sheave 22B. A hydraulic cylinder 22D having a drive stroke for one stage can accommodate 14 levels of storage shelves.
[0028]
The balance pulley mechanism 23 includes a weight wire 23A as a weight connecting cable whose end is connected to a counterweight 23B as a counterweight member, and a balance movable sheave 23C as a moving weight pulley member and a balance as a fixed weight pulley member. It is hung around the fixed sheave 23D, and the base end is fixed. In the configuration example of FIG. 1, a pair of weight wire 23A, balance movable sheave 23C, and balance fixed sheave 23D are provided for one counter weight 23B.
[0029]
The movable balance sheave 23C is mounted on a movable balance base 23F suspended from and supported by the connection beam 22G of the drive system pulley mechanism 22 via the connection cable 23E with the rotation axis being horizontal. Is moved up and down in conjunction with the movable sheave 22B. The base end of the weight wire 23A is also fixed to the movable balance base 23F.
[0030]
The balance fixed sheave 23D is fixed to the building side with its rotation axis parallel to the balance movable sheave 23C.
[0031]
The balance movable sheave 23C and the balance fixed sheave 23D are formed in a plurality of parallel grooves similar to the movable sheave 22B and the fixed sheave 22C of the drive system pulley mechanism 22, and the weight wire 23A winds over the balance movable sheave 23C. It is turned to turn it upward and downward, and then it is wound around the lower side of the fixed balance sheave 23D to turn it upward and downward, and is wrapped so as to repeat this for the number of grooves.
[0032]
In the balance pulley mechanism 23 configured as described above, since the weight wire 23A is routed around the movable balance sheave 23C, the movable balance sheave 23C is a movable pulley, and the moving amount of the counterweight 23B is adjusted. Is multiple times the amount of movement of the balance movable sheave 23C. Thus, the weight of the counterweight 23B is reduced to one part of the number of strips as compared with the case where the counterweight 23B is directly suspended and mounted on the connecting beam 22G, and the absolute weight can be reduced.
[0033]
That is, when the number of turns of the weight wire 23A around the movable movable sheave 23C is 3.5 as in the example of FIG. 1, the counterweight 23B moves seven times the movable movable sheave 23C. Since the cage 11 moves 14 times the movable sheave 22B as described above, the counterweight 23B moves by half the moving amount of the cage 11, and its weight may be 1/7 that of the case where the cage is directly suspended and mounted on the connecting beam 22G. The weight of the counterweight 23B is set so that the cage 11 on which the vehicle is not mounted has a weight balance that is reduced by a predetermined amount.
[0034]
The balance mechanism 30 is configured such that a weight rope 31 serving as a weight cable connected to the cage 11 is connected to a movable sheave 22 via a balance wire sheave 32 serving as a balance cable pulley member disposed above an elevating area of the cage 11. It is arranged on the side of the lifting area, and the other end is connected to a balance weight 33 as a balance weight member.
[0035]
In the balance mechanism 30 configured as described above, since the balance weight 33 is not connected via the moving pulley, the balance weight 33 can be balanced with the cage 11 at a 1: 1 weight ratio.
[0036]
That is, as shown in FIG. 1, if the movement amount of the counterweight 23B in the balance pulley mechanism 23 is half of that of the cage 11, the counterweight 23B needs twice the weight of the cage 11; The weight 33 may have a weight of 1: 1 with respect to the cage 11, and can be balanced with the cage 11 by the balance weight 33 having a lighter absolute weight.
[0037]
In the lifting / lowering transport device 10 configured as described above, the lifting / lowering mechanism 20 drives the cage 11 up and down by the drive system pulley mechanism 22, and balances the weight of the cage 11 by the balance system pulley mechanism 23 and the balance mechanism 30. All of these mechanisms are located on the side of the lifting area of the cage 11, so that a large lifting and lowering transport stroke can be obtained without disposing a large and heavy driving device at the top, and the whole can be made small and lightweight. You can do it.
[0038]
Note that the present application is not limited to the above configuration example, and can be appropriately changed. For example, it may be constituted by only the lifting mechanism 20 without providing the balance mechanism 30, and the number of turns of the weight wire 23A of the drive system pulley mechanism 22 and the balance system pulley mechanism 23 can be arbitrarily set. is there.
[0039]

Fixed weight pulley member of parallel groove The main part of the lifting mechanism is located on the side of the elevating area of the cage, and the driving pulley mechanism has a multi-stage pulley member. The cage moves greatly with a small stroke of the lifting drive means to become a moving pulley, while the balance pulley mechanism has a moving weight pulley member that is a multi-stage moving pulley, so the amount of movement of the counterweight member is larger than that of the moving pulley member. The cage weight is balanced by the lighter counterweight members. As a result, a large lifting / lowering transport stroke can be obtained without arranging a large and heavy driving device at the top, and the whole can be configured to be small and lightweight.
[0040]

Further, in addition to the above configuration, the cage and the balance weight member are connected by a weight cable arranged via a balance cable pulley member arranged above the elevating area of the cage, and as the cage elevates. The balance weight member is provided with a balance device configured to move up and down on its side. In this balance device, the cage side and the balance weight member correspond at a weight ratio of 1: 1 and are light. The balance weight member can be balanced with the cage, and the entire lifting / lowering transport device can be made lightweight.
[0042]
In addition, the support rope is connected to the opposite corner of the cage, and the weight rope of the balance device is connected to the other corner, so that the configuration is simplified. Thus, the weight of the cage can be balanced by a light balance weight member, and the cage can be moved up and down by the lifting / lowering drive means with a small force, so that the entire lifting / lowering transport device can be made compact and lightweight.
