Description

  The present invention relates to a mechanical multi-stage parking apparatus in which a plurality of transporters on which a vehicle is mounted are stored in a stacked manner at least in the vertical direction, and each vehicle transports to a loading / unloading position, thereby loading / unloading the vehicle. is there.

  Conventionally, various types of mechanical multistage parking apparatuses using a carrier have been put into practical use. As an example, FIG. 10 shows a mechanical type in which a plurality of carriers are stacked in one or a plurality of rows, arbitrarily selected carriers are moved up and down, traversed to a predetermined loading / unloading position, and loading / unloading is performed. The multistage parking apparatus 1 is shown schematically. This mechanical multistage parking apparatus 1 has a configuration in which a plurality of transporters 2, 3, 4, 5 are vertically arranged in a single row. In the illustrated example, a skeleton frame 12 is assembled on the ground portion, and three stages of transporters 2, 3, and 4 are provided in the skeleton frame 12. In addition, an underground pit 13 is formed in the underground portion, and only one stage of the transporter 5 is provided in the underground pit 13. In the present description, the respective carriers are referred to as the uppermost stage carrier 2, the ground middle stage carrier 3, the ground surface stage carrier 4, and the underground stage carrier 5.

  The uppermost transporter 2 is provided for each row as illustrated. Moreover, each carrier 2a-2c is provided with the raising / lowering mechanism using a four-point hanging raising / lowering chain, and raises / lowers each independently between the uppermost stage and the ground surface GL. FIG. 4 shows a state where the transporters 2a and 2b are positioned at the uppermost stage and the transporter 2c is lowered to the ground surface.

  The second intermediate ground transporter 3 from the top is one row lower than the uppermost transporter 2, and includes two transporters 3a and 3b in the illustrated example. Each of the transporters 3a and 3b is suspended from a frame (not shown) that moves left and right on the travel rail 6 by a travel wheel (not shown) via a lift mechanism similar to the lift device of the uppermost transporter 2. ing. Therefore, each of the ground middle stage transporters 3a and 3b can move up and down between the second stage and the ground surface GL, and can traverse.

The ground surface transporter 4 in the third level from the top is provided with two transporters 4a and 4b, one line less than the uppermost transporter 2 as in the middle ground transporter 3. Moreover, each carrier 4a, 4b can traverse the ground surface GL. The traversing mechanism of the ground surface transporter 4 has a structure that travels on traveling rails laid on the front and rear positions of the opening of the underground pit 13 with traveling wheels.
Furthermore, the underground transport device 5 is provided for each row in the same manner as the uppermost transport device 2. And by the raising / lowering apparatus using a raising / lowering chain and a balance chain, each carrier 5a, 5b, 5c can rise independently from the pit 13 to the ground surface GL.

  And the mechanical multistage parking apparatus 1 calls in / out of a vehicle by calling the carrier selected arbitrarily from each said carrier 2,3,4,5 to the ground surface GL. Further, when calling the underground transporter 5 to the ground surface GL, the transporter 2 is raised to the uppermost stage so as not to hinder the rise of the corresponding underground transporter, and the second-stage transporter 3 and the third-stage transporter 4 can be retracted in the horizontal direction. Moreover, when calling the transporters 2 and 3 to the ground surface GL, other transporters can be retracted to a position that does not hinder the lowering of the corresponding transporter.

  In addition, the front of the pallet (4a, 4b, 2c) located on the ground surface GL is closed with a gate 10, and the interior and exterior of the mechanical multistage parking device 1 are simply separated from each other, thereby improving safety. I am letting. When the vehicles 8 and 9 are loaded and unloaded, the gate 10 can be stored underground or can be raised to a position where it does not interfere with the vehicles 8 and 9. In addition, the part shown with the code | symbol 11 in FIG. 10 is the fence fixed to the beam of the parking apparatus. The vehicle 8 is a high roof vehicle such as a one-box vehicle, and is stored in the uppermost transporter 2 that is not subject to height restrictions. On the other hand, the vehicle 9 is a normal roof vehicle having a low vehicle height, such as a sedan, and is stored in the ground intermediate carrier 3, the ground surface carrier 4, and the underground breaker 5 set to the standard accommodation vehicle height.

By the way, it is necessary to give each said carrying device appropriate intensity | strength and rigidity, aiming at weight reduction as much as possible. Therefore, a reinforcing member made of a square steel pipe is fixed to the back surface (lower surface) of the main rail, which is a main part of the transporter, or a reinforcing plate is fixed to the back side of the main rail. Has been invented (see, for example, Patent Document 2).
11 to 13 show an uppermost transporter 2 as an example of a conventional transporter. The main rail 14 of the uppermost transporter 2 includes a road section 15 that extends in parallel with the loading / unloading direction of the vehicle and forms a road surface of both the left and right wheels of the vehicle, and a middle / high section that protrudes upward between the road sections. 16 and the side member portion 17 protruding upward from the outer end portion of the roadway portion 15 are integrally press-molded to ensure the strength in the longitudinal direction. Furthermore, the cross members 18 to 21 made of angle steel or groove steel are fixed to the back surface of the main rail 14 so that the strength of the main rail 14 in the vehicle width direction is ensured. In addition, this structure is the same also for other carriers.

By the way, so-called compact cars have become popular among private cars in recent years. In order to increase the accommodation efficiency as much as possible within the limited vehicle dimensions, compact cars with a higher vehicle height are becoming mainstream. However, since the standard accommodation vehicle height of the mechanical parking device is set to 1550 mm, a compact car with a high vehicle height cannot use the mechanical parking device and parks in a so-called flat parking lot. It is pointed out that it is necessary. For this reason, even when the ceiling height is limited, it is required to further increase the accommodation height of the mechanical parking device. As a countermeasure, it is necessary to widen the internal space by suppressing the required space height of the structural members of the mechanical parking apparatus. And the cross members 18-21 which protrude below from the back surface of the main rail 14 became a big factor which obstructs the thickness reduction of a carrier.
Moreover, if this cross member is to be replaced with a thin one, it is necessary to use a large number of cross members, which causes problems such as an increase in weight, which can be an effective means for achieving a thinner transporter. Not.

For example, in the case of the underground transporter 5, it is necessary to deepen the underground pit 13 by the amount that the cross members 18 to 21 protrude from the back surface of the main rail 14, and the overall cost of the mechanical parking device 1. It was also a factor to increase
Furthermore, as shown in the example of FIG. 10, since the plurality of carriers 2, 3, 4, 5 are stored in the mechanical parking apparatus in a vertically stacked manner, for example, the vehicle 8 stored in the ground surface carrier 4 is stored. The cross members 18 to 21 that protrude downward from the back surface of the main rail 14 of the intermediate ground transporter 3 walk on the ground intermediate transporter 3 to get in and out of the vehicle 9 during the loading and unloading of the vehicle. The driver was forced to take an unreasonable posture in order to avoid the cross members 18 to 21, and this contributed to the deterioration of the usability of the mechanical parking device.

Such a problem is not limited to the so-called up-and-down and traverse type mechanical parking device shown in FIG. 10, but also applies to mechanical parking devices using a carrier.
The present invention has been made in view of the above-mentioned problems, and the object of the present invention is to promote the thinning while ensuring the strength and rigidity necessary for the transporter, and to accommodate the height of the mechanical parking device per level. Is to improve convenience for the user.

  In order to solve the above problems, the mechanical parking apparatus according to the present invention is configured such that a plurality of carriers mounted on a vehicle are stored in a plurality of layers at least in the vertical direction, and each carrier moves to an entry / exit position. A mechanical parking device for entering and exiting a vehicle, wherein the transporter extends in parallel with the entrance and exit direction of the vehicle and forms a road surface of the left and right wheels of the vehicle, and between the road portion A main rail formed by a middle-high portion projecting upward at a height lower than the minimum ground clearance of the vehicle and a side member portion projecting upward from the outer end portion of the road portion is above the road portion. A part or the whole protrudes and is reinforced by a plurality of cross members provided with a cross-sectional area for obtaining necessary strength and rigidity.

  According to the present invention, the cross member that reinforces the main rail of the transporter is provided with a cross-sectional area for obtaining a required strength by partly or entirely protruding above the road portion. Therefore, it is possible to eliminate the reinforcing member protruding downward from the back surface of the main rail or to significantly reduce the protruding amount while ensuring the strength and rigidity necessary for the main rail. Therefore, the lower space of the transporter is expanded.

In the present invention, it is preferable that the cross member protrudes with a shape and a height that allow the vehicle to easily get over.
With this configuration, it is possible to alleviate vehicle swaying (feeling of being caught) or the like when the wheel rides over the cross member protruding upward from the road part of the main rail.

In the present invention, it is preferable that the cross member penetrates the middle and high portions and is fixed to the upper surface of the road section on both sides of the middle and high portions.
According to this configuration, the shape of the cross member and the installation work can be simplified.
In the present invention, the cross member may include a vehicle stop fixed to the upper surface of the roadway portion. Further, the cross member may include a cross member fixed along the rear end of the main rail in the vehicle exit direction. In other words, since it is assumed that the wheel does not rest behind the vehicle stop, there is a problem of getting over the cross member fixed along the rear end of the vehicle exit direction [vehicle sway (feeling of being caught), etc.] ] Is not applicable. Therefore, it is possible to expand the cross-sectional shape of the cross member to a height equal to or higher than that of the car stop.

  In the present invention, the cross member may include a cross member fixed along the front end portion of the main rail in the vehicle exit direction. In this case, the cross member of the main rail fixed along the front end of the vehicle exit direction may protrude from the front end of the vehicle exit direction forward of the vehicle exit direction. The cross member fixed along the front end portion of the vehicle in the exit direction of the rail may be fixed with a member serving as an attachment point of the hanging tool or the bearing.

  Since this invention was comprised in this way, it becomes possible to promote thickness reduction, ensuring the intensity | strength and rigidity which are required for a carrier, and to increase the accommodation height per one hierarchy of a mechanical parking apparatus.

The best mode for carrying out the present invention will be described below with reference to the accompanying drawings.
Here, parts that are the same as or correspond to those in the prior art are denoted by the same reference numerals, and detailed description thereof is omitted.

1 and 2 includes a main road rail 14 that extends in parallel with the vehicle loading / unloading direction and forms the road surface of both the left and right wheels of the vehicle, A middle height portion 16 projecting upward at a height lower than the minimum ground height of the vehicle (a general minimum ground height that can be assumed in consideration of various vehicles) between the road portions 15 and the outside of the road portion 15. The side member portion 17 protruding upward from the end portion is integrally formed by press molding, and the strength in the longitudinal direction is ensured by the uneven shape.
Further, on the surface (upper surface) of the road section 15 of the main rail 14 near the front end of the vehicle exit direction (left side in FIG. 1), both sides of the middle high section 16 are connected so that the middle high section 16 and the side member 17 are connected. The cross member 24 divided into two is fixed. As shown in FIG. 9A, the cross member 24 is made of a groove steel having a so-called hat-shaped cross section, and a necessary strength is ensured. And since the contact surface 24a of the tire at the time of entering / exiting the vehicle is an inclined surface, it is easy to get over the vehicle. Further, the protruding height of the cross member 24 from the upper surface of the road section 15 is also suppressed to a height at which the vehicle can easily get over.

  A cross member 26 is also fixed to the surface of the roadway 15 at the middle of the main rail 14. Further, a cross member 28 is also provided on the surface of the roadway portion 15 of the main rail 14 near the rear end portion in the vehicle exit direction. Each of the cross members 24, 26, and 28 has a cross-sectional area for obtaining a required strength. Unlike the cross member 24, the cross members 26 and 28 are made of angle steel. It is fixed across the road sections 15 on both sides across the section 16. In addition, the cross member 26 functions also as a vehicle stop which makes the rear wheel of the vehicle which approachs the transporter 22 contact | abut, and has a shape suitable for preventing the riding of a wheel. Further, since the cross member 28 is not particularly limited in shape as long as it has a required strength, it uses a simple-shaped angle steel.

  Further, in order to further improve the strength and rigidity in the vehicle width direction of the main rail 14 together with the cross members 24, 26, and 28, the back surface of the center tunnel 16 does not exceed the step between the road portion 15 and the middle-high portion 16. A cross member 30 having a height is fixed (see FIG. 2). Note that all of the cross members 24, 26, 28 and 30 are fixed to the main rail 14 by welding.

Now, an application example of the transporter 22 is shown in FIGS. 3 to FIG. 5 has the same configuration as the carrier 22 shown in FIGS. 1 and 2 with respect to the main rail 14, which is a main component. However, as a difference from the transporter 22, the cross member 34 disposed near the front end of the main rail 14 in the vehicle exit direction (left side in FIG. 3) and the middle portion of the main rail 14 has a vehicle width. A square steel pipe that is continuous in the direction is used. As shown in FIG. 5A, through holes 16 a and 17 a for passing the cross member 34 are press-formed in the middle high portion 16 and the side member portion 17 of the main rail 14. FIG. 5B shows a state in which the cross member 34 is fixed to the main rail 14. The protruding height of the cross member 34 from the upper surface of the roadway portion 15 is suppressed to a height at which the vehicle can easily get over.
Further, in the drawing, a portion indicated by reference numeral 36 is an approach (stepping platform) provided to alleviate a step when the wheel gets over the cross member 34. In the illustrated example, the approach 36 uses a round bar having a diameter smaller than the protruding height of the cross member 34 to simplify the part. However, an approach having a wedge-shaped cross section may be used (note that the approach 36 is illustrated). In this example, the cross member 34 is a 60 × 30 square steel pipe, and the approach is φ25.)

Note that the through holes 16a and 17a are formed larger than the cross-sectional shape of the cross member 34 in order to allow a press working tolerance, and are sealed by a hatched portion indicated by a symbol s in FIG. Further, both end portions of the cross member 34 are fixed to a gusset plate 38 (see FIGS. 5B and 5C) having a crank-type cross section fixed to the side member portion 17. Further, the cross member 34 is installed in a slightly floating state with respect to the road portion 15 and is tack-welded to the surface of the road portion 15 at a shaded portion indicated by reference sign w (FIG. 5C). In addition, drainage around the cross member 34 is ensured.
Further, a cross member 40 made of a belt-like plate is fixed to the transporter 32 by welding so as to protrude upward of the roadway portion 15 along the rear end portion of the main rail 14 in the vehicle exit direction. In addition, in order to further improve the strength of the main rail 14 in the vehicle width direction together with the cross members 24, 26, and 28, a belt-like flat plate is formed on the back surface of the main rail 14 so as to straddle the side member portions 17 on both sides. A cross member 42 (FIG. 4B) made of is welded. In addition, the cross member 26 which functions as a car stop similarly to the transporter 22 is also fixed to the transporter 32. And the cross member 42 is provided in the vicinity of the range in which the wheel is located of the vehicle positioned by the cross member 26.

FIG. 6 to FIG. 8 show still another application example of the transporters 22 and 32. The carrier 44 shown in FIGS. 6 to 8 has the same configuration as that of the carriers 22 and 32 with respect to the main rail 14 which is a main part thereof. However, as a difference from the transporters 22 and 32, the cross member 46 is fixed along the front end of the main rail 14 in the vehicle exit direction (left side in FIG. 6).
The cross member 46 of the transporter 44 is a steel pipe having a larger cross-sectional area than that of the cross member 34 (FIG. 3) of the transporter 32 (in the example shown, the cross member 46 is a 100 × 50 square type. Steel pipe). The protruding height of the cross member 46 from the upper surface of the road portion 15 is suppressed to a height at which the vehicle can easily get over. As shown in FIG. 8 (a), a notch 14a for fixing the cross member 46 along the front end of the main rail 14 in the exit direction of the vehicle includes a road portion 15, a middle high portion 16, a side portion. It is press-molded so as to be formed over each part of the member part 17. A drain hole 15 b is formed in the vicinity of the front end of the roadway portion 15.
Then, the cross member 46 is fixed by welding along the notch 14a of the main rail 14 and is positioned above the roadway portion 15 as shown in FIGS. 8 (b) and 9 (b). The part protrudes. Note that both end portions of the cross member 46 are fixed to a backing plate 48 fixed to the side member portion 17 of the main rail 14 as shown in FIG. Furthermore, a hanging metal fitting 50 is welded to the cross member 46 and the backing plate 48 for fixing a sprocket or the like around which the lifting chain of the transporter 44 is hung.

Similarly to the transporter 32, the cross member 40 made of a belt-like plate is also fixed to the transporter 44 by welding along the rear end of the main rail 14 in the vehicle exit direction. In addition, for the purpose of further improving the strength of the main rail 14 in the vehicle width direction together with the cross members 46, 40, the back surface of the main rail 14 is formed of a belt-like flat plate so as to straddle the side member portions 17 on both sides. A plurality of cross members 52 (see FIGS. 6B, 7B, and 8C) are welded. Furthermore, although illustration is omitted, it is possible to use a cross member 26 (see FIG. 1) that functions as a car stop as well as the transporter 22 for the transporter 44. And it is desirable for the cross member 52 to be provided at least in the vicinity of the range where the wheels of the vehicle are located.
As shown in FIG. 9C, the transporter 44 is configured such that the length of the main rail 14 is shortened and the cross member 46 protrudes from the front end portion of the shortened main rail 14, as shown in FIG. It is also possible to do.

The operational effects obtained by the embodiment of the present invention having the above-described configuration are as follows.
First, the cross members 24, 26, 28, 34, and 40 that reinforce the main rail 14 of the transporters 22, 32, and 44 are partially or wholly protruded above the road section 15, thereby obtaining necessary strength. The cross-sectional area for this is ensured. Therefore, in order to give the main rail 14 the necessary strength, it is possible to eliminate the reinforcing member protruding downward from the back surface of the main rail 14, or to greatly reduce the protruding amount of the reinforcing member. As a result, in the state where the transporters 22, 32, and 44 are accommodated in the mechanical parking device, the space below the transporters 22, 32, and 44 is expanded. Therefore, it is possible to increase the accommodation height per one level of the mechanical parking device, and it is possible to use the mechanical parking device even for a vehicle with a high vehicle height that has been increasing in recent years (specific example). As a result, the height from the upper surface of the carriage section 15 of the transporter 22 to the lower surface of the transporter is reduced by 45 mm as compared with the transporter 3 of FIG.
Further, by eliminating the reinforcing member protruding downward from the back surface of the main rail, or by greatly reducing the protruding amount of the reinforcing member, a sufficient height is given to the side members 17 of the transporters 22, 32, and 44. Is possible.

Further, if the embodiment of the present invention is applied to an underground transporter, it is possible to eliminate the reinforcing member protruding downward from the back surface of the main rail 14 or to greatly reduce the protruding amount of the reinforcing member. Therefore, the underground pit 13 (FIG. 10) becomes shallow, and it becomes possible to avoid an increase in the installation cost of the mechanical parking device 1.
Furthermore, when the driver gets on and off the vehicle on the transporters 22, 32, 44, the protrusion on the lower surface of the transporter located above is eliminated, so that the driver has an unreasonable posture to avoid obstacles. It is possible to eliminate the cause of the deterioration of the usability of the mechanical parking device such as being forced.

Further, since the cross members 24, 34, 46 of the transporters 22, 32, 44 protrude above the road portion 15 with a shape and height that can easily get over the vehicle, the cross members 24, It is possible to alleviate the shaking of the vehicle when the wheels get over 34 and 46.
Further, in the case of the transporter 32 shown in FIGS. 3 to 5, the cross member 34 is made of a square steel pipe, penetrates the middle-high portion 16, and is formed on the upper surface of the road portion 15 on both sides of the middle-high portion 16. Since the structure is fixed, the cross member shape and installation work can be simplified compared to the cross member 24 having a hat-shaped cross section separated to the left and right of the transporter 22 shown in FIGS. Will be.

  Further, among the plurality of cross members fixed so as to protrude from the upper surface of the road portion 15, the cross member 26 functions as a vehicle stopper. Integration of functions of members and car stops will be achieved. Further, the cross member 40 fixed along the rear end portion of the main rail 14 along the vehicle exit direction surrounds the rear end portion of the transporters 34 and 46 in the form of a wall. It will function as a preliminary car stop.

Further, when the cross member 46 is fixed along the front end of the main rail 14 along the vehicle exit direction, the cross member 46 is projected from the front end of the main rail 14 in the vehicle exit direction to the vehicle exit direction. Can also be installed (FIG. 9C). In particular, by increasing the cross-sectional area of the cross member 46 provided along the front end of the vehicle exit direction, the effect of improving the strength of the main rail 14 in the vehicle width direction is increased, and the number of cross members 46 to be used is reduced. It is also possible to make it.
Further, the cross-sectional area of the cross member 46 can be enlarged by increasing the amount of protrusion from the lower surface of the main rail 14. Note that it is desirable that the amount of protrusion from the lower surface of the main rail 14 is limited in advance to the range of the amount of subsidence at the central portion in the width direction allowed for the main rail 14.
And since the cross member 46 with a large cross-sectional area has high strength, even if a member that becomes an attachment point of a hanging tool or a bearing such as the hanging bracket attachment metal 50 is fixed, the load is dispersed by the cross member 46. In addition, since it is transmitted to the main rail 14, the transmission efficiency of the force is improved, and the reinforcing member for receiving the load can be omitted.

  In addition, when the carrying device according to the embodiment of the present invention is adopted in the mechanical parking device having a structure in which the underground carrier 5 and the pit 13 are omitted from the up-and-down traverse type mechanical parking device illustrated in FIG. There is an advantage that the gap between the ground surface transporter 4 and the ground surface GL can be expanded, or the amount of digging down the ground surface can be reduced.
