Description

The present invention relates to a vertical circulation parking apparatus, a cage in which a vehicle is mounted and vertically circulated by a main chain , and a method for modifying the cage .

  2. Description of the Related Art Conventionally, a vertical circulation parking device (hereinafter also simply referred to as “parking device”) that circulates a cage for storing a vehicle in a parking tower (tower) in a vertical direction is known. As shown in FIG. 11, in the parking apparatus 51, a plurality of cages 53 for mounting and housing the vehicle M are provided inside the parking tower 52.

  Further, an upper sprocket 55 and a lower sprocket 56 are provided on the beam (structure) of the parking tower 52, and the cage 53 is circulated by an endless main chain 57 wound between the sprockets 55, 56. Be made. The main chain 57 is constructed by connecting a number of links. The suspension shaft 59 of the cage 53 is suspended by T-shaped attachment links 58 attached to the main chain 57 at predetermined intervals.

  As shown in FIG. 12, the cage 53 includes a pallet 60 on which the vehicle M is mounted and a portal cage frame 61 erected on the front and rear ends of the pallet 60. As is apparent when referring also to FIGS. 13 to 16, the side of the pallet 60 is fixed to the lower end of the cage frame 61. A pallet bracket 62 is fixed to the side of the pallet 60, and a cage frame bracket 63 is fixed to the lower end of each cage frame 61. The pallet 60 and the cage frame 61 are connected by connecting the brackets 62 and 63 with bolts and nuts.

  As shown in FIG. 11, when the upper sprocket 55 is rotated by a circulation drive device 64 such as a motor, the main chain 57 is rotated and the cage 53 is circulated up and down. The cage 53 is configured to be reversed by being guided by the upper turning guide 65 and the lower turning guide 66 at the upper end and the lower end of the circulation path R through which the cage 53 circulates.

  In this parking apparatus, the ground floor of the parking tower 52 is a loading / unloading floor 67, and a loading / unloading port 68 is provided here. The entrance / exit 68 is an entrance through which the vehicle M enters the parking tower 52. Inside the entrance / exit 68, one cage 53 for entering the inbound vehicle is located.

  In installation work of such a parking device, construction of a steel-structured parking tower 52, installation of a machine base (mounting platform for various machines) 69 and a circulation drive device 64 (drive source, transmission mechanism, etc.) on the upper receiving beam In addition, the upper and lower sprockets 55 and 56 and the accompanying structural members are installed. Next, the main chain 57 is hung around the upper and lower sprockets 55 and 56. The cage 53 is attached by circulating the main chain 57 so that the attachment links 58 are sequentially positioned at the lowermost position (position facing the entrance / exit 68).

  In this parking device, the vehicle M directly enters the 60 road surface MS of the pallet of the cage 53 from the entry floor surface F of the entry / exit floor 67, so that the landing of the road surface MS with respect to the entry floor surface F can be performed without any trouble. The allowable value of the level difference (the level difference between the entry floor surface F and the 60 road surface of the pallet) is set. For example, as shown in FIG. 17, the landing step is set to about +30 mm at the maximum. That is, the pallet vehicle road surface MS is planned to be about 30 mm higher than the entry floor surface F. The positive side takes into account the secular growth of the main chain and the elastic elongation when the vehicle enters. If this step is too large on the + side, the bottom of the vehicle will rub against the center rising part of the pallet 60 when the vehicle enters, and if it is too large on the-side, it will rub against the corner between the entry floor surface F and the shallow pallet landing pit P. There is a fear. Therefore, at the final stage of the installation work, it is confirmed whether or not the landing level of each cage 53 on the entry / exit floor is within the allowable value.

  In the actual parking device, the tolerance of the steel frame of the parking tower, the tolerance and deflection of the machine base itself, the error of the height of the receiving beam located 20 to 40m from the ground where the machine base is installed, the pin of the main chain Various manufacturing tolerances such as bushing tolerances and inevitable errors accumulate. Furthermore, due to the weight of the cage 53 and the main chain 57 and the weight of many mounted vehicles, the main chain 57 is stretched (initial elongation, elastic elongation, tolerance elongation). When the above tolerance, error, deflection, and elongation are included, the maximum is close to 40 mm.

  Therefore, even if the parking device is completed as designed, it is necessary to finally confirm whether or not the landing step is within an allowable value. As a result, if there is a cage in which the landing step exceeds an allowable value, a large-scale additional adjustment work such as raising the entire machine base and changing the attachment position of the guide member accompanying it is unavoidable.

There is no prior art that attempts to solve this problem. For example, Patent Document 1 is known as a disclosure of the configuration of a vertical circulation parking apparatus.
JP-A-53-70274

The present invention provides a modified method for changing the internal height of a cage of a vertical circulation parking device, provides a cage modified by the modified method , and a vertical circulation type equipped with the cage The purpose is to provide a parking device .

A modified cage for a vertical circulation parking apparatus according to the present invention is a cage suspended on a main circulation chain that circulates vertically, and is arranged on a pallet for mounting on a vehicle and on each of a front end and a rear end of the pallet. For changing the vertical length of the cage that can be detachably inserted between the pallet and the cage cage frame and at least the lower end of the cage frame on the vehicle entry / exit side of the pallet and the pallet And a connecting member .

  It is preferable that the connecting member is made of a plate material and connected to each of the cage frame bracket and the pallet bracket by bolts and nuts, since the configuration becomes simple.

  The connection member is configured to be connected to each of the cage frame bracket and the pallet bracket by a bolt and nut, and the bolt connection portion with the cage frame bracket in the connection member is formed in a plurality of upper and lower stages, By selecting and using the bolt connection portion, the height position of the pallet with respect to the cage frame can be changed. As the bolt connection portion, for example, a bolt hole can be employed.

Vertical circulation parking system of the present invention is provided with any one of the cages of which have been described above, the competent chain for vertically circulated hung the cage.

  According to the present invention, by performing a slight adjustment work of exchanging connection members only for a cage that requires adjustment of the landing level, the landing step difference of the cage can be kept within an allowable value. This eliminates the need for large-scale construction such as raising the machine base and reattaching the accompanying structural members as in the prior art.

  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a longitudinal sectional view showing an embodiment of a vertical circulation parking apparatus according to the present invention. 2 is a cross-sectional view taken along the line II-II in FIG.

  In the parking apparatus 1 shown in FIG. 1, the ground floor of the parking tower 2 is an entry / exit floor 3, and an entrance / exit 4 is provided here. This entrance / exit 4 is an entrance through which the vehicle M enters the parking tower 2 and is provided on the front side in a direction perpendicular to the paper surface of FIG. Inside the parking tower 2, a plurality of cages 5 for mounting and accommodating the vehicle M are provided.

  On the other hand, an upper sprocket 7 and a lower sprocket 8 are installed on the beams in the parking tower 2, and an endless main chain 9 is hung around them. The cage 5 is suspended from the main chain 9. On the receiving beam 6 of the parking tower 2, a circulation drive device (drive motor 20b, speed reducer 20c, brake 20d, transmission mechanism 20e, etc.) 20 is installed via a machine base 20a. The main chain 9 is rotated by the upper sprocket 7 that is rotated by the circulation drive device 20.

  As shown in FIG. 2, the cage 5 includes a pallet 10 for mounting on a vehicle, and a front side of a portal type (almost U-shaped or rectangular) erected on both ends (front and rear ends) of the pallet 10 in the longitudinal direction. The cage frame 11 and the rear cage frame 12, and a suspension shaft 14 that connects the upper end central portions of the cage frames via brackets 13 provided on the upper portions of the cage frames 11 and 12. The front cage frame 11 is a cage frame located on the back side in the parking tower 2, and the rear cage frame 12 is a cage frame on the side facing the loading / unloading port 4, that is, a cage frame on the vehicle entry / exit side of the pallet. . As will be described later, the lower ends of the cage frames 11 and 12 are detachably connected to the side of the pallet 10.

  Both ends of the suspension shaft 14 are suspended from the main chain 9 via T-shaped attachment links 15 provided on the main chain 9 at predetermined intervals. Thereby, the suspension shaft 14 is supported by the attachment link 15 provided in the orthogonal direction.

  Further, a lower roller 16 for guiding the lower part of the cage is provided on the side of the pallet 10 of the cage 5, and shoulder rollers 17 are provided on both sides of the bracket 13 provided on the upper part of the front cage frame 11. Yes. The shoulder roller 17 is installed only on one of the front and rear cage frames 11 and 12 (usually the front cage frame 11).

  As shown in FIG. 1, a linear guide 18 and a linear guide 19 for guiding the lower roller 16 are provided in a vertical portion of the circulation path R of the parking tower 2. Thereby, when the cage 5 moves in the vertical direction of the parking tower 2, the lower roller 16 is guided by the linear guide 18 and the linear guide 19 so as to be able to move up and down stably. At this time, a guide roller (not shown) of the main chain 9 is guided by a chain guide (not shown) provided on the beam.

  Further, an upper turning guide 21 for guiding the shoulder roller 17 is provided at the upper reversing portion of the circulation path R of the parking tower 2, and a lower turning guide 22 for guiding the shoulder roller 19 is provided at the lower reversing portion. ing. Thus, when the cage 5 is reversed at the upper reversing part and the lower reversing part of the parking tower 2, the shoulder roller 17 is guided by being engaged with the upper turning guide 21 and the lower turning guide 22.

  In this way, the cage 5 suspended only by the suspension shaft 14 is restricted from moving left and right during vertical movement by the lower roller 16 provided on the pallet 10, and by the shoulder roller 17 provided on the cage frame 11, The horizontal movement at the time of upside down is restricted, and the cage 5 is configured not to swing around the suspension shaft 14.

  2 and 3 show a connection mechanism between the pallet 10 and the cage frames 11 and 12 in the cage. A pallet bracket 23 is fixed to the side of the pallet 10, and a cage frame bracket 24 is fixed to the lower ends of the cage frames 11 and 12. A connecting member 25 is interposed between the brackets 23 and 24. By connecting the brackets 23 and 24 to the connection member 25 with bolts 26 and nuts 27, the pallet 10 and the cage frames 11 and 12 are detachably connected. This connection member 25 is for adjusting the height dimension from the suspension point of the cage 5 (the height position of the suspension shaft 14) to the road surface of the pallet 10. In other words, it is for adjusting the level of landing of the cage on the entry / exit floor.

  As shown in FIG. 2, in this embodiment, the front and rear cage frames 11, 12 are provided with connecting members 25, but the present invention is not limited to this configuration. You may interpose only in the cage frame 12 of the rear side. As can be seen from FIG. 2, when the vehicle enters and exits the pallet, the bottom of the vehicle may rub against the rear end (left side in the figure) of the center rising portion 10a of the pallet and the cage landing pit P. This is because the rear corner C is. That is, the vehicle M does not pass through the front end (right side in the drawing) of the pallet. Therefore, it may be interposed only in the rear cage frame 12 that may require the adjustment of the landing level.

  The connecting member 25 is shown in detail in FIGS. As illustrated, the cage frame bracket 24 is made of a plate material fixed to the lower end of the cage frame by welding. The cage frame bracket 24 extends along the longitudinal direction of the cage frame, and a bolt hole 29a is formed there. The pallet bracket 23 is formed of a U-shaped plate material, and is fixed to the outer surface of the side rising portions 10b on both sides of the pallet 10 by welding. A bolt hole 30a is formed on a surface of the pallet bracket 23 that protrudes outward from the upper end curved portion 10c of the pallet side portion rising portion 10b. In this embodiment, both brackets 23 and 24 have substantially the same configuration as that of the conventional one.

  The connecting member 25 is made of a plate material, and the lower inner surface (the surface on the pallet side) is in contact with the outer surface of the pallet bracket 23 (the surface on which the cage frame bracket conventionally contacts), and the upper outer surface (with the pallet). The surface on the opposite side is connected with a bolt and nut while being in contact with the inner surface of the cage frame bracket 24 (the surface on the pallet side and the surface on which the pallet frame bracket conventionally contacts). The outer surface of the pallet bracket 23 and the inner surface of the cage frame bracket 24 are so-called flush (on the same virtual plane). The surface of the connecting member 25 that contacts the pallet frame bracket 23 and the surface that contacts the cage frame bracket 24 are flush with each other. Therefore, as shown in FIGS. 3 and 6, the plate-like connection member 25 has a central portion bent at two points by the thickness of the connection member, and an upper side and a lower side from the central portion. Are formed in parallel.

  A bolt hole 29b for connecting to the cage frame bracket 24 is formed in the vicinity of one end (near the upper end in the figure) of the connection member 25, and the pallet bracket 23 is provided in the vicinity of the other end (near the lower end in the figure). A bolt hole 30b is formed for connection. Of course, the number and position of the illustrated bolt holes 29b and 30b are merely examples, and the present invention is not limited thereto.

  As shown in FIG. 6, a plurality of connecting members having different sizes are prepared as spare parts in the parking apparatus 1 of the present embodiment. Here, the size is a distance L between the upper and lower bolt holes 29b, 30b. FIG. 6 shows an example of a combination of connecting members having different sizes. A long connection member 25A having a long bolt hole separation distance L1, a short connection member 25C having a short bolt hole separation distance L3, and a medium connection member 25B having an intermediate bolt hole separation distance L2. It can be easily understood that the use of the connection member 25 having a long distance L reduces the landing level of the cage, and the use of the short connection member 25 increases the landing level of the cage. The connection member in the present invention is not limited to these three types.

  7 and 8 show usage examples of the three types of connection members 25A, 25B, and 25C. For example, first, the medium length connecting member 25B is attached to all the cages during installation work (FIG. 7A). In design, considering all of dimensional tolerance, error, elongation, and deflection, the median value of the expected variation in the landing level is about +30 mm at the maximum, that is, the road surface MS of the pallet 10 is in relation to the floor surface F. It is planned to be about 30 mm higher. When the landing level after the completion of the construction is confirmed, when the actual step hu exceeds the upper landing step allowable value huo as shown in FIG. 7 (a), as shown in FIG. 7 (b). By changing to the long connecting member 25A, the pallet 10 can be lowered downward to reduce the level difference hu and be within the upper and lower landing level allowable values huo, hdo. The connection member 25 is replaced while the pallet 10 is suspended by a chain block or the like.

  On the other hand, when the actual level difference hd when the medium-sized connecting member 25B is attached as shown in FIG. 8A exceeds the lower landing step allowable value hdo, as shown in FIG. By changing to the connection member 25C, the pallet 10 can be lifted upward to reduce the step hd and fit within the upper and lower landing step allowable values huo and hdo. The above steps hu, huo, hd and hdo all indicate steps between the entry floor surface F and the road surface MS of the pallet 10.

  It is not always necessary to use a connecting member when adjusting the landing level. Even if the medium connecting member 25B is replaced with the short connecting member 25C, if the step hd does not fit within the lower landing step allowable value hdo, the allowable value of the cage internal height (reference numeral H described later) is taken into consideration. The pallet bracket 23 and the cage frame bracket 24 may be directly connected without using a connection member.

  Reference numeral 28 denotes a reinforcing material for the pallet 10. This connecting member 25 is made of a plate and formed into a shape devised so that it can also be applied to existing conventional cages using brackets 23 and 24 as shown in FIGS. ing. However, in the present invention, both the brackets and the connection member are not limited to the above configuration. It has sufficient strength, can avoid interference with the mounted vehicle and other members during vertical circulation, etc., and can be detachably interposed between the pallet 10 and the cages 11 and 12 Any configuration may be used as long as it is. For example, a pipe may be used instead of the plate material. Further, the cage frame and the pallet may be connected by a known adjusting bolt, and the position of the pallet with respect to the cage frame may be moved up and down by rotating the adjusting bolt. That is, the adjustment bolt is attached to one of the cage frame and the pallet so as not to move up and down and is rotatable, and the nut to be screwed to the adjustment bolt is fixed to the other.

  FIG. 9 shows another connecting member 31. The connection member 31 has the same basic shape as the connection member 25 described above, but has an upper portion longer than the central bent portion, and a plurality of bolt holes 29b for connecting to the cage frame bracket 24 in the vertical direction. It differs from the connection member 25 described above in that it is formed with steps (six steps in this embodiment). With this configuration, the connection position of the connection member 31 with the cage frame bracket 24 can be changed. Thereby, the vertical position of the pallet 10 with respect to the cage frames 11 and 12 can be changed only by the connection member 31 without having to replace the connection member.

  FIG. 10 shows an example in which the connecting member 25 is used for purposes other than the adjustment of the landing level. The cage 5 accommodates a vehicle HM (so-called semi-high roof vehicle) having a relatively high vehicle height. This cage is originally a cage that accommodates ordinary vehicles (vehicles with a relatively low vehicle height), and the internal height of the vehicle accommodating portion (indicated by symbol H in the figure) is insufficient to mount a semi-high roof vehicle. However, the internal height H is increased using the connecting member. In this case, the connecting member 25 must be attached to both the front and rear cage frames 11 and 12.

  For example, by installing the connecting member having the above-described distance L between the upper and lower bolt holes 29b, 30b of 200 mm in the existing ordinary vehicle cage having an internal height H of 1650 mm shown in FIG. The cage 5 for a semi-high roof vehicle having an internal height H of 1850 mm can be easily modified. Since the structure of the cage 5 is substantially the same as that of the cage 5 shown in FIG. 3, the same reference numerals are given to the same structural parts, and the description thereof is omitted. Although a semi-high roof vehicle is illustrated, a connection member for a high roof vehicle (longer than that for a semi-high roof vehicle) can also be applied.

  Conventionally, when remodeling an existing parking system for ordinary cars to accommodate semi-high roof cars and high roof cars, the cage for ordinary cars is removed from the main chain and removed from the parking tower. A cage for high roof cars (high roof cars) is carried into the parking tower and attached to the main chain. This is a daunting task. If the connection members 25 and 31 are used, it is not necessary to carry out and carry in the cage. Furthermore, it is not necessary to attach or detach the cage to the main chain. Compared to these operations, operations such as replacement of connecting members and shortening and extension of the main chain are simple and easy. The connecting member described above will skillfully solve the problem of frequent semi-high roof vehicles (high roof vehicles) of parking devices.

  According to the parking apparatus of the present invention, the landing level of the cage can be adjusted very easily, so that the construction period can be shortened and the additional adjustment work cost can be reduced. Furthermore, even when the main chain is extended as a result of long-term use of the parking device and the landing level difference of the cage is likely to deviate from the allowable value, it is possible to easily adjust only the cage.
