Mechanical parking facilities

Abstract

To provide mechanical parking facilities that have compact constitution for supporting carriageway surfaces of pallets differing in height from a pallet lower end to a carriageway surface at the same height.SOLUTION: Mechanical parking facilities comprise a first pallet which is relatively short in height of a carriageway surface from a pallet supported part and a second pallet which is relatively long in height of a carriageway surface from a pellet supported part, and equipment which moves up and down a pallet loaded with a vehicle at a moving-on floor. The moving-on floor comprises a movable pallet receiver which is at a retreat position retreated from a moving-up / down path when equipment is mounted with the second pallet and moves down to the moving-on floor, and at a moving-forward position where the equipment moves forward to a moving-up / down path when mounted with the first pallet and moving down to the moving-on floor to support the carriageway surface of the first pallet at the same level with a moving-on floor. The movable pallet receiver rotates to a horizontal direction, and moves forward to or back from the moving-up / down path.SELECTED DRAWING: Figure 3

Description

[Technical field]

[0001] The present invention relates to a mechanical parking facility that allows the use of a mixture of pallets with different heights from the bottom end of the pallet to the road surface. [Background technology]

[0002] Conventionally, there is a mechanical parking facility equipped with a pallet rotation device (180-degree rotation type, etc.) on the boarding floor or carrier at the boarding floor so that vehicles can drive forward both when entering and leaving the facility.

[0003] On the other hand, even in this type of mechanical parking equipment, there is a demand for barrier-free access by removing obstacles (uneven surfaces) so that wheelchair users can use it.For example, the requirements for barrier-free access in elevator-type parking equipment include making the entire top surface (carriageway surface) of the pallet on which the vehicle is loaded flat, and when this flat-topped pallet is placed on the boarding floor, making the difference in level between the surrounding deck and the boarding floor small so that wheelchairs can travel through it.

[0004] Therefore, the applicant has filed a patent application for a mechanical parking facility that can store a mixture of normal pallets and pallets with a flat driving surface, as prior art of this type (see, for example, Patent Document 1). In this mechanical parking facility, when a normal pallet is supported at the boarding floor, a swing arm is extended from the fixed pillar into the elevator shaft, and the pallet is supported by a support member provided at the upper end of the swing arm. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2015-113673 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, in the invention of the above-mentioned Patent Document 1, it is difficult to increase the amount of advance of the swing arm that advances from the fixed column into the elevator shaft, and the support position of the pallet may be limited. For example, in order to change the support position of the pallet further inward (towards the center of the pallet), the configuration of the swing arm, etc. becomes large, which may make it difficult to apply.

[0007] Therefore, an object of the present invention is to provide a mechanical parking facility that can compactly form a configuration that supports the road surfaces of pallets, which have different heights from the supported part to the road surface, at the same height. [Means for solving the problem]

[0008] In order to achieve the above object, the present invention provides a mechanical parking facility including a first pallet in which the height of the road surface relative to the supported portion of the pallet is relatively low, a second pallet in which the height of the road surface relative to the supported portion of the pallet is relatively high, an entrance floor for a vehicle to enter and leave between the first pallet or the second pallet, and a carrier for raising and lowering the first pallet and the second pallet between a storage unit, the entrance floor includes a movable pallet support that retreats to a position that does not prevent the second pallet from descending to a position where the road surface is the same level as the entrance floor when the second pallet is placed on the entrance floor, and that becomes an advanced position when the first pallet is placed on the entrance floor and supports the road surface of the first pallet at the same level as the entrance floor, the movable pallet support being provided at least in the four corners of the elevator shaft and configured to advance to or retreat from the advanced position by rotating horizontally. The "four corners" in this specification and the claims include a range in which a pallet having a rectangular shape in plan view can be appropriately supported.

[0009] With this configuration, when the first pallet, whose height of the roadway surface is relatively low, is supported at the boarding floor, the first pallet can be supported at the advanced position where the movable pallet support is advanced into the hoistway, and the roadway surface can be supported at the same level as the boarding floor. When the second pallet, whose height of the roadway surface is relatively high, is supported at the boarding floor, for example, the movable pallet support can be in the retreated position retreated from the hoistway, and the carrier carrying the second pallet can be stopped at a predetermined position to support the roadway surface at the same level as the boarding floor. In this way, the first pallet, whose height of the roadway surface is relatively low, is supported by the movable pallet support in the advanced position, and the second pallet, whose height of the roadway surface is relatively high, is retreated to a position that does not prevent the roadway surface from descending to a position where the roadway surface is at the same level as the boarding floor, so that the roadway surface of the pallet, whose height from the supported part of the pallet to the roadway surface is different, can be adjusted to the boarding floor of the boarding floor. In addition, as a method of supporting the second pallet at the boarding floor, in addition to stopping the carrier with the second pallet placed on it (see Figure 7 described below), it is possible to support it by a pallet support other than the movable pallet support (see Figure 8 described below).

[0010] The movable pallet support may also be configured to support the road surface of the pallet from below.

[0011] With this configuration, the movable pallet support supports the road surface of the pallet from below, thereby providing adequate support for the portion close to the vehicle tires.

[0012] In addition, the movable pallet support may be configured so that at the front of the elevator shaft, a support part that directly supports the first pallet rotates and advances from the longitudinal center of the elevator shaft toward the longitudinal front, and at the rear of the elevator shaft, the support part rotates and advances from the longitudinal center of the elevator shaft toward the longitudinal rear.

[0013] With this configuration, the movable pallet support supports the four corners at the front and rear ends of the pallet, and can be stored inside both longitudinal ends of the pallet when it is withdrawn from the elevator shaft.

[0014] The movable pallet support may also include a support axis arranged in a vertical direction, a support member that rotates around the support axis, and a driving machine that rotates the support member around the support axis, and may also include a control unit that simultaneously drives the driving machine to rotate the support member and advance it into the elevator when the first pallet is placed at the boarding floor.

[0015] With this configuration, the support members of each movable pallet support are advanced into the elevator shaft by synchronously driving the driving machines, so that the pallet can be appropriately supported by the support members in response to the raising and lowering movement of the pallet.

[0016] The driving machine may have a driving shaft that rotates the support member and faces downward, and a portion above the driving shaft may be covered with a cover member having an airtight structure.

[0017] With this configuration, even if the driving machine is arranged inside a pit, the driving machine can be prevented from being submerged by the air inside the airtight cover member when it is submerged in water. Effect of the Invention

[0018] According to the present invention, in a mechanical parking facility in which the direction of vehicles entering and leaving the facility is the same as the direction of vehicles moving up and down the elevator on a carrier, it is possible to form a compact configuration that supports the road surfaces of pallets at the same height, even though the heights from the bottom end of the pallets to the road surface are different.

[0020] An embodiment of the present invention will be described below with reference to the drawings. In the following embodiment, a 180-degree rotating elevator-type parking facility 1 with lower entry will be described as an example of a mechanical parking facility. Note that the concepts of front, rear, left and right directions in this specification and claims are the same as the concepts of front, rear, left and right directions shown in FIG.

[0021] (Elevator parking facility) Fig. 1 is a front cross-sectional view showing an elevator-type parking facility 1 according to one embodiment. Fig. 2 is an enlarged plan view taken along the line II-II shown in Fig. 1. In Fig. 2, the carriage 11 and the first pallet 40 are shown by solid lines, and the layout and operation of the movable pallet receiver 60 at the entrance floor 30 are shown in outline.

[0022] As shown in Fig. 1, the elevator type parking facility 1 has a parking tower 2 formed of a steel frame structure. The parking tower 2 is formed in a frame shape by main columns 5 arranged vertically to form the outer shape, and upper beams 3 and other horizontal beams 4 (Fig. 2) arranged horizontally to connect the main columns 5. The parking tower 2 is provided with shelf columns 6 inside the main columns 5, and a parking shelf (storage section) 7 is provided on the shelf columns 6. The parking tower 2 is provided with a control device 80 for the elevator type parking facility 1. The control device 80 is just one example.

[0023] A hoistway 10 for raising and lowering carriers 11 is provided in the center of the width of the parking tower 2, and multiple parking shelves 7 are provided on the left and right sides of the hoistway 10. In the parking shelves 7, a first pallet 40 and a second pallet 50 on which vehicles V are loaded are stored.

[0024] The first pallet 40 is a standard pallet, with side rising portions 41 that are bent upward on both sides in the longitudinal direction in the width direction, and a concave road surface 42 along which the tires of the vehicle V pass is formed on the inside of which is a central raised portion 43. The part of the first pallet 40 that is supported is below the road surface 42. A horizontal loading member 44 extending in the width direction is provided on the lower part of this first pallet 40, and the horizontal loading member 44 is supported by the carrier 11.

[0025] In addition, the second pallet 50 has a roadway deck 56 at the same height as the side rising portion 51 and the central raised portion 53 over the entire length of the concave portion 52 formed in the same manner as the concave roadway surface 42 of the first pallet 40. The lower portion of the concave portion 52 of the second pallet 50 is the supported portion. As a result, the entire upper surface of the second pallet 50 is formed flat. The upper surface of the roadway deck 56 of the second pallet 50 is the roadway surface 55. The second pallet 50 has a cross-sectional shape similar to that of the first pallet 40 to give it rigidity, and the roadway deck 56 is a barrier-free pallet with a flat upper surface. A horizontal loading member 54 extending in the width direction is also provided at the lower portion of the second pallet 50, and the horizontal loading member 54 is supported by the carrier 11.

[0026] The carriage 11 is raised and lowered by a lifting drive device 13 provided on the boarding floor 30. A movable pulley 12 is provided at the bottom of the carriage 11, and one end of a rope-like body 15 ("rope-like body" refers to "wire rope" or the like) hung on the movable pulley 12 is fixed to a fixed part 8 of the parking tower 2. The other end of the rope-like body 15 is wound around a traction sheave 14 of the lifting drive device 13, and then a counterweight 16 is suspended by the movable pulley. The counterweight 16 reduces the force required to hoist the carriage 11. Therefore, the carriage 11 can be raised and lowered by the movable pulley system by driving the traction sheave 14 to hoist and lower the rope-like body 15. A traverse drive device 18 is provided on the carriage 11, and the pallet 40 (50) is transferred between the carriage 11 and each parking shelf 7 by the traverse drive device 18.

[0027] The entrance floor 30 of the parking tower 2 is provided at the same level as the ground surface 9. The entrance floor 30 is provided with an entrance floor 32 that is connected to the vehicle runway surfaces 42, 55 of the pallets 40, 50 that allow the vehicles V to enter and leave the parking lot. A pit 31 is provided facing downwards at the entrance floor 30 so as to be connected to the elevator 10. A slewing drive device 19 is provided within the pit 31 for lifting and rotating the pallet 40 (50) placed on the carriage 11. The slewing drive device 19 lifts the pallet 40 (50) at the entrance floor 30 and rotates it 180°. The traverse drive device 18 and the slewing drive device 19 can be implemented by known means.

[0028] As shown in Fig. 3 described later, a vehicle width sensor P1 is provided on the boarding floor 30 to detect the left and right protrusion of the vehicle V, and the maximum width of the vehicle V that can be loaded onto the pallet 40 without being detected by the vehicle width sensor P1 is W, and the minimum width of the vehicle that can be loaded onto the pallet 40 is T. In other words, the vehicle V that can be loaded onto the pallet 40 and stored in this parking facility has a width of T to W.

[0029] As shown in FIG. 2, the boarding floor 30 is provided with a movable pallet support 60 that supports the vehicle road surface 42 of the first pallet 40 at the same level as the upper surface of the boarding floor 32. The movable pallet support 60 is provided at the four corners of the elevator shaft 10 at the boarding floor 30. When the carrier 11 loads the second pallet 50 and descends to the boarding floor 30, the movable pallet support 60 is in a retreat position R retreated from the elevator shaft 10. When the carrier 11 loads the first pallet 40 and descends to the boarding floor 30, the movable pallet support 60 is in an advance position F advancing into the elevator shaft 10, and supports the vehicle road surface 42 of the first pallet 40 at the same level as the surface of the boarding floor 32. The configuration of the present invention is also applicable to a parking facility of, for example, a 90-degree boarding type in which the direction of the vehicle V when entering and leaving the parking facility is different from the direction of the vehicle V when ascending and descending. In this case, it is the turning device 19 that lowers the pallet 40 (50) to a position at the boarding floor 30 where the vehicle road surface 42 and the boarding floor 32 coincide after turning, and when the turning device 19 lowers the first pallet 40, the movable pallet support 60 advances to support the pallet (Figure 6), and when the second pallet 50 is lowered, the movable pallet support 60 is retracted and the raising and lowering of the turning device 19 with the second pallet 50 placed on it is stopped at a position where the vehicle road surface 55 of the second pallet 50 is at the same level as the boarding floor 32 (Figure 7).

[0030] The movable pallet receiver 60 is configured such that the support member 61 (support portion) rotates horizontally to advance into or retreat from the hoistway 10. At the front of the hoistway 10, the support member 61 is configured to rotate from the longitudinal center of the hoistway 10 toward the longitudinal front to advance. At the rear of the hoistway 10, the support member 61 is configured to rotate from the longitudinal center of the hoistway 10 toward the longitudinal rear to advance. The movable pallet receiver 60 is configured such that the support member 61 rotates horizontally, thereby increasing the amount of advance into the hoistway 10 while being compact. In addition, the support member 61 is configured to retreat to the longitudinal center of the hoistway 10 where a large space can be secured, and to be accommodated inside both longitudinal ends of the pallet 40 (50) in the retreated state.

[0031] The elevator parking facility 1 also includes a control unit 63 that simultaneously drives the driving machine 62 (FIG. 3) of the movable pallet support 60 when the first pallet 40 is placed on the entrance floor 30 to rotate the support member 61 and advance it into the elevator shaft 10. The control unit 63 in this embodiment is included in the control device 80 of the elevator parking facility 1.

[0032] The control unit 63 has a processor, a volatile memory, a non-volatile memory, an I / O interface, etc. The synchronous driving of the driving machine 62 of the movable pallet support 60 by the control unit 63 is realized by the processor performing calculations using the volatile memory based on a program stored in the non-volatile memory. The control unit 63 synchronously drives the driving machine 62 of the movable pallet support 60 to advance the support member 61 into the elevator shaft 10 based on the fact that the first pallet 40 is being raised and lowered by the carriage 11 and that the carriage 11 has descended to the fixed position P of the boarding floor 30.

[0033] (Movable pallet holder) Fig. 3 is an enlarged view taken along the line III-III of Fig. 2. Fig. 4 is a front view of the movable pallet support 60 shown in Fig. 3. Fig. 5 is a plan view of the movable pallet support 60 shown in Fig. 4.

[0034] As shown in Fig. 3, the movable pallet support 60 is provided on the upper part of a stand 64 provided in the pit 31. The stand 64 may be configured in any way so long as it is capable of fixing the movable pallet support 60 to its upper surface. By configuring the movable pallet support 60 to be fixed to the stand 64 provided in the pit 31, the movable pallet support 60 can be designed separately from the components in the elevator-type parking facility 1 (for example, the structure on the entrance floor 30), allowing for freedom in design.

[0035] The movable pallet support 60 is configured to support the road surface 42 of the first pallet 40 from below by means of support members 61 (support parts). The range (range on either the left or right side) over which the support members 61 of the movable pallet support 60 support the road surface 42 of the first pallet 40 from below can be a distance C = (WT) / 2 ± 50 mm inward from the left or right end of the maximum width W described above. This makes it possible for the movable pallet support 60 to support the area directly below the tires of the vehicle V or the area close to the tires.

[0036] Furthermore, in the movable pallet receiver 60 of this embodiment, the drive machine 62 is disposed facing downward, and the part above the drive shaft 65 is covered with an airtight cover member 66. The cover member 66 is structured so that even if the entire drive machine 62 is submerged in water, the area around the drive machine 62 will not be submerged due to the air inside. A known structure can be used for the cover member 66.

[0037] As shown in Figures 4 and 5, the movable pallet support 60 has a horizontal member 67 fixed to the stand 64, and a vertical member 68 provided in the vertical direction from the horizontal member 67. The horizontal member 67 and the vertical member 68 are fixed integrally. A driver 62 is provided on the horizontal member 67. The driver 62 has a drive shaft 65 attached to it facing downward. A drive sprocket 72 provided on the drive shaft 65 is provided in an opening 67a of the horizontal member 67.

[0038] Support brackets 69 are provided at the top and bottom of the vertical member 68, protruding in the horizontal direction. A support shaft 70 is supported by the support brackets 69, which is provided in the vertical direction. The support shaft 70 is supported by a bearing 71 provided on the support brackets 69. The support shaft 70 is provided with a support member 61 that rotates integrally with the support shaft 70. A driven sprocket 73 is provided at the lower end of the support shaft 70, and an idle sprocket 74 is provided between the driven sprocket 73 and the driving sprocket 72. A drive chain 75 is hung between the driving sprocket 72, the idle sprocket 74, and the driven sprocket 73. The idle sprocket 74 allows the drive chain 75 to pass through the front and rear positions of the vertical member 68. A stopper 76 is provided on the support bracket 69, and is adapted to abut against the stopper 76 when the support member 61 advances into the hoistway 10. The support member 61 abuts against the stopper 76 at a rotation angle of about 90°. The position where the support member 61 abuts against the stopper 76 is the advanced position F. A receiving member 77 is fixed to the upper part of the advanced side of the support member 61. The receiving member 77 can be made of, for example, resin, rubber, or the like.

[0039] The movable pallet support 60 can rotate the support members 61 around the support shaft 70 by rotating the drive machine 62. When the first pallet 40 is placed on the entrance floor 30, the control unit 63 simultaneously drives the drive machines 62 to rotate all of the support members 61 and advance them into the elevator shaft 10.

[0040] In this embodiment, the method of rotating the support member 61 by the driver 62 is a chain drive system, but a link drive system using a link member can also be used, and a configuration for rotating the support member 61 other than this embodiment can also be adopted.

[0041] In this embodiment, the movable pallet receiver 60 is unitized from the horizontal member 67 that is fixed to the stand 64 up to the upper part. By unitizing the movable pallet receiver 60, it is possible to improve the workability during transportation and assembly.

[0042] (Operation of movable pallet receiver) Fig. 6 is a front view of the first pallet 40 supported on the boarding floor 30. Fig. 7 is a front view of the second pallet 50 supported on the boarding floor 30. The carriage 11 in these figures shows lateral travel rollers 21 that support from below the loading horizontal member 44 (54) provided in the width direction on the underside of the pallet 40 (50) and move it lateraly, and side rollers 22 that guide the loading horizontal member 44 (54) from the front and rear.

[0043] As shown in Fig. 6, when the first pallet 40 is lowered toward the boarding floor 30 by the carriage 11, when the carriage 11 reaches a position a predetermined height above the boarding floor 32, the driver 62 (Fig. 3) of the movable pallet support 60 is driven, and the support member 61 is rotated about the support shaft 70. As a result, the support member 61 is advanced toward the elevator shaft 10 and stops at the advanced position F (Fig. 6).

[0044] Thereafter, the carrier 11 is further lowered, and the underside (supported portion) of the vehicle road surface 42 at the four corners of the first pallet 40 is supported by the support members 61 (support portion). Even after the first pallet 40 is supported by the support members 61, the carrier 11 is lowered from the boarding floor 32 to a fixed position P below and stopped. As a result, the first pallet 40 can be supported by the support members 61 of the movable pallet support 60, with the vehicle road surface 42 of the first pallet 40 supported at the same level as the boarding floor 32.

[0045] On the other hand, as shown in Fig. 7, when the second pallet 50 is lowered toward the boarding floor 30 by the carrier 11, the driving machine 62 of the movable pallet support 60 is not driven, and the carrier 11 is lowered to the fixed position P. With the carrier 11 lowered to the fixed position P, the vehicle runway surface 55 of the second pallet 50 placed on the carrier 11 can be supported at the same level as the boarding floor 32.

[0046] In this way, the first pallet 40 (standard pallet) having a relatively low height of the vehicle road surface 42 is placed on the carriage 11 and transported to the boarding floor 30, where it is supported by the support member 61 of the movable pallet support 60 that can move back and forth at the boarding floor 30. The carriage 11 then descends to a fixed position P that is lower than this and stops. Also, the second pallet 50 (barrier-free pallet) having a relatively high height of the vehicle road surface 55 stops at the fixed position P while being placed on the carriage 11 and transported to the boarding floor 30. That is, the carriage 11 that transports the first pallet 40 and the second pallet 50 to the boarding floor 30 stops at the fixed position P in either case, but the first pallet 40 and the second pallet 50 can be supported in a state where the respective vehicle road surfaces 42, 55 are at the same level as the upper surface of the boarding floor 32.

[0047] Moreover, by configuring the movable pallet support 60 supporting the first pallet 40 to rotate horizontally by the support member 61, the amount of advancement into the hoistway 10 can be increased in a small space on the boarding floor 30, and the movable pallet support 60 can be formed compactly. Note that a part of the movable pallet support 60 may be in the hoistway in the retracted position of the movable pallet support 60 as long as it is in a position that does not interfere with the lifting and lowering of the pallets 40, 50 and the carriage 11. In this case, for example, the movable pallet support 60 may be configured to support the second pallet 50 in the retracted position. In this case, at least one of the supported part and the supporting part may be different from when supporting the first pallet 40, and the vehicle road surface 55 when supporting the second pallet 50 may be configured to be at the same level as the upper surface of the boarding floor 32.

[0048] (Other variations) The mechanical parking facility is not limited to the elevator type parking facility 1 in the above embodiment. For example, the present invention can be applied to a mechanical parking facility such as an intermediate entry type where the parking shelf 7 is located below the entrance floor 30, and the position of the entrance floor 30 is not limited to the above embodiment. Furthermore, as shown in Figure 8, the configuration for supporting the second pallet 50, which has a relatively high height from the supported portion to the vehicle road surface 55, on the entrance floor 30 may be such that the second pallet 50 is supported by a movable or fixed pallet support 80 different from the movable pallet support 60 that supports the first pallet 40.

[0049] In addition, the arrangement of the lifting drive device 13 that raises and lowers the carrier 11 is also one example, and the lifting drive device 13 may be an upper drive type arranged above the upper beam 3, and the arrangement of the lifting drive device 13 is not limited to the above embodiment.

[0050] Furthermore, the above-described embodiment is merely an example, and various modifications are possible without departing from the spirit of the present invention, and the present invention is not limited to the above-described embodiment.

[0051] (Summary) As described above, according to the elevator-type parking facility (mechanical parking facility) 1, the movable pallet support 60 that supports the first pallet 40 at a predetermined height on the boarding floor 30 can be configured compactly, which makes it possible to improve the degree of freedom in designing the boarding floor 30. For example, even in a configuration in which the lifting drive device 13 that raises and lowers the carrier 11 is disposed on the boarding floor 30, it is possible to easily provide the movable pallet support 60.

[0052] Therefore, it is possible to configure a compact elevator-type parking facility (mechanical parking facility) 1 that can be used in combination with pallets 40, 50 having different heights from the bottom end of the pallet to the vehicle road surfaces 42, 55. [Explanation of symbols]
