Description

  The present invention relates to a mechanical parking apparatus in which a vehicle is moved in a vertical direction and a horizontal direction for storage.

  As a parking device that efficiently uses the underground space, there is a plane reciprocating mechanical parking device, and as one type thereof, a hoistway of a lift device for transporting a vehicle mounting pallet in the vertical direction; There is a type in which the pallet is arranged so as to intersect with a carriage traveling path of a movable carriage for conveying the pallet in the horizontal direction.

  That is, such a mechanical parking device has a vehicle storage structure in which a storage shelf is provided in one or a plurality of rows on one side or both sides of a carriage traveling path for reciprocating a movable carriage capable of mounting the pallet in the basement. A plurality of layers are provided on the top and bottom.

  A hoistway of the lift device for raising and lowering a lift frame on which the pallet can be mounted is provided at a position penetrating the bogie travel path of the vehicle storage layer at each stage in the vertical direction.

  The lift frame and the movable carriage can support the pallet at a position where they do not interfere with each other. In addition, in a state where the movable carriages of the vehicle storage layers of the respective stages are arranged at the intersections with the hoistways in the carriage traveling path, the lift frame is operated so as to pass in the vertical direction with respect to the movable carriage. It is made to be able to. Accordingly, the pallet can be transferred to each other so that the pallet is transferred from the lift frame or the moving carriage positioned above before the passing operation to the moving carriage or the lift frame positioned above after the passing operation. It is like that.

  Furthermore, at the top of the hoistway, an entry / exit space is provided for allowing the vehicle to enter and exit the pallet mounted on the lift frame disposed at the upper end of the hoistway.

  According to the plane reciprocating mechanical parking device having the above-described configuration, when the vehicle is to be stored, the pallet mounted on the lift frame in advance is placed in the storage space. In this state, the vehicle is placed on the pallet and placed.

  Next, the pallet on which the vehicle is placed is lowered by the lowering operation of the lift frame by the lift device. At this time, by placing the moving carriage of the vehicle storage layer on the desired floor in advance at the crossing position with the hoistway, when the lift frame passes from above the moving carriage, the vehicle mounting is performed. The placed pallet is transferred from the lift frame to the movable carriage.

  Then, after moving the movable carriage to the side position of the target storage shelf on the carriage traveling path, the vehicle is moved side by side with the pallet by the transfer device equipped on the movable carriage or the storage shelf. It is made to store in the storage shelf.

  The unloading operation for moving the vehicle stored in the storage shelf of the vehicle storage layer on a certain floor to the loading / unloading space is performed in the reverse procedure.

  By the way, in the mechanical parking device, when the pallet is transferred between the lift frame of the lift device and the movable carriage of the vehicle storage layer at each stage, the lift frame is disposed at the predetermined position. It is necessary to move so as to pass in the vertical direction with respect to the moved carriage. Therefore, when the pallet is transferred to and from the movable carriage of the lowermost vehicle storage layer, the lift frame needs to be lowered to a position lower than the lowermost vehicle storage layer.

  Therefore, in the conventional mechanical parking apparatus, it is usually necessary to provide a lift pit for receiving the lift frame lowered to a position lower than the lowermost vehicle storage layer on the lower end side of the hoistway. It was.

  However, since the lift pits need to be provided in the inner bottom of the housing in which each vehicle storage layer is accommodated, the floor surface is partially dug down, which increases the cost and labor for forming the housing. This is the actual situation.

  Therefore, in recent years, a mechanical parking device has been proposed in which a lift pit on the lower end side of the hoistway of the lift device can be eliminated.

  That is, in the same configuration as the mechanical parking device described above, a pallet support means (pallet support device) capable of supporting the pallet so as to be movable up and down on the upper side of the mobile trolley is provided at least on the mobile trolley in the lowermost vehicle storage layer. It is provided as a configuration. Furthermore, the lift frame is configured to include engagement / disengagement switching means (arms) capable of switching between a locked state and a non-locked state with respect to the peripheral portion of the lower surface of the pallet.

  According to the mechanical parking apparatus having such a configuration, when the pallet supported by the lift frame is moved to the movable carriage of the lowermost vehicle storage layer, the pallet support means of the movable carriage is raised. In this state, the lift frame is lowered to a position passing the upper end surface of the pallet support means, so that the pallet is received on the movable carriage side via the pallet support means. Thereafter, after the engaging / disengaging switching means of the lift frame is brought into the pallet non-locking state, the lift frame is raised. Thereafter, in the mobile carriage, the pallet support means is lowered to lower the pallet to a position corresponding to the lowermost vehicle storage layer (see, for example, Patent Document 1).

  As another configuration, a height position corresponding to the storage shelf of the lowermost vehicle storage layer, the pallet on the movable vehicle that can travel on the carriage travel path of the lowermost vehicle storage layer, as described above. To the height position corresponding to the storage shelf of the vehicle storage layer above the lowermost stage, and the lift frame is locked to the pallet. It has been proposed to have a configuration including an engagement / disengagement switching means (an engagement / disengagement device) capable of switching between a state and an unlocked state.

  According to the mechanical parking apparatus having such a configuration, the lowermost moving carriage moves the vehicle to the lowermost and upper vehicle storage layers in accordance with the range of pallet lifting by the pallet supporting means. It can be used concurrently (for example, see Patent Document 2).

  Furthermore, the movable carriage 3 of the third-stage vehicle storage layer 1c from the bottom is retracted to an arbitrary position that does not interfere with the lift frame 13 that moves the hoistway 9 up and down.

  In this state, when the entered vehicle c is placed on the pallet 2 in the loading / unloading space 19, the lift device 8 is as shown by the two-dot chain line arrow in FIG. It operates to lower the lift frame 13 and lowers the pallet 2 on which the vehicle c is placed.

  Thereafter, as shown in FIG. 5B, the lift device 8 moves the lift frame 13 on which the pallet 2 is mounted to a height corresponding to the carriage travel rail 7b of the vehicle storage layer 1b in the second stage from the bottom. It is lowered below the movable carriage 3 which is arranged on the traveling rail member 23 at the position and is on standby. At this time, the lift frame 13 moves so as to pass from the upper side with respect to the movable carriage 3 and descends to a position below the movable carriage 3, so that at this time, the pallet 2 on which the vehicle c is placed. Is transferred from the lift frame 13 onto the movable carriage 3. The lift frame 13 does not reach the inner bottom surface of the casing 6 that is the lower end of the hoistway 9 even if the lift frame 13 is lowered below the movable carriage 3.

  Next, as shown in FIG. 5 (c), the moving carriage 3 on which the pallet 2 on which the vehicle c is mounted is mounted on the traveling rail member 23 from the bottom of the vehicle storage layer 1b.

When the vehicle storage layer 1b of the second stage is moved onto the carriage travel rail 7b, the vehicle storage layer 1b is moved as it is to the side position of the target storage shelf 5, and then the carriage 3 is moved in the same manner as described above. Alternatively, the vehicle c may be laterally fed together with the pallet 2 by the transfer device installed in the storage shelf 5 and stored in the target storage shelf 5.

  Furthermore, when storing the vehicle c using the mechanical parking apparatus of the present invention, when storing the vehicle c in the storage shelf 5 of the vehicle storage layer 1c at the third level from the bottom, What is necessary is just to carry out similarly to a mechanical parking apparatus.

  That is, the lift frame 13 mounted with the pallet 2 on which the vehicle c is placed in the storage / exit space 19 intersects the hoistway 9 in the bogie travel path 4 of the vehicle storage layer 1c at the third level from the bottom. It is lowered to a position that passes the moving carriage 3 that has been previously arranged in the part.

As a result, the pallet 2 on which the vehicle c is placed is delivered from above to the movable carriage 3 of the third-stage vehicle storage layer 1c. Thereafter, the movable carriage 3 is moved from the bottom to the side position of the target storage shelf 5 of the third-stage vehicle storage layer 1c, and the pallet 2 as in the case of the vehicle storage layers 1a and 1b described above. Each vehicle c may be laterally fed and stored in the storage shelf 5 for the above purpose.

  On the other hand, when the vehicle c stored in the storage shelf 5 of each of the vehicle storage layers 1a, 1b, and 1c is to be delivered, the pallet 2 on which the vehicle c is placed is reversed in the reverse procedure to that when the vehicle c is received. What is necessary is just to make it move to the said storage / exit space 19. FIG.

Even when the pallet 2 on which the vehicle c is placed in 1a is stored, it is possible to eliminate the need to provide a lift pit on the lower end side of the hoistway 9.

  Further, it is not necessary to provide a lifting mechanism for the pallet 2 in the movable carriage 3 used for transporting the pallet 2 to the lowermost vehicle storage layer 1a. Therefore, the mobile carriage 3 can have the same configuration as that of the mobile carriage in the conventional mechanical parking apparatus, and the configuration, size and weight of the mobile carriage 3 are avoided. be able to.

  Further, the lift frame 13 of the lift device 8 need not be provided with an engagement / disengagement switching means for switching between the locked state and the non-locked state with respect to the pallet 2. Therefore, the lift frame 13 can have the same configuration as the lift frame in the conventional mechanical parking apparatus, and avoids the complexity, size increase, and weight increase of the configuration of the lift frame 13. be able to.

  As described above, the lift frame 13 of the lift device 8 is not provided with an engagement / disengagement switching means for the pallet 2 from the viewpoint of avoiding a complicated configuration, an increase in size, and an increase in weight. However, it is possible to adopt a configuration in which the lift frame 13 is provided with the engagement / disengagement switching means. In this case, when the vehicle c is stored in the lowermost vehicle storage layer 1a by the procedure shown in FIGS. 5A, 5B, 5C, 5D, and 5E, FIG. As described above, even if the moving carriage 3 carrying the pallet 2 is moved from the bottom to the carriage traveling rail 7b of the second-stage vehicle storage layer 1b and is temporarily retracted from the hoistway 9, the lift frame 13 can be raised above the moving carriage 3. Therefore, when performing the warehousing process of the vehicle c, it is possible to expect the effect of reducing the number of processes and shortening the processing time.

  In addition, this invention is not limited only to the said embodiment, You may apply to the mechanical parking apparatus of the type with which the vehicle containment layer was laminated | stacked four or more steps. Further, if a plurality of vehicle storage layers are provided below the entry / exit space 19, the present invention may be applied to a mechanical parking apparatus having a vehicle storage layer above the entry / exit space.

  From the viewpoint of increasing the efficiency of loading and unloading of the vehicle c as much as possible, the elevating traveling rail device 22 has a vehicle storage layer 1b that is the second stage from the bottom from the position of the carriage traveling rail 7a in the lowermost vehicle storage layer 1a. It is desirable to have a function of moving the traveling rail member 23 up and down in the range up to the height position of the bogie running rail 7b in the vehicle, but the height corresponding to the bogie running rail of the vehicle containment layer located at the third or higher level from the bottom. You may make it provide the function to raise the traveling rail member 23 to a position. In this case, the vehicle storage layer in the hoistway 9 in a range in which the travel rail member 23 of the elevating travel rail device 22 can be raised and lowered is configured such that a portion disposed in the hoistway 9 is removed from the bogie travel rail. That's fine.

  In the above embodiment, the configuration in which one mobile carriage 3 is shared by the lowermost vehicle storage layer 1a and the lowermost vehicle storage layer 1b is shown. A plurality of mobile trolleys 3 may be operated in the vehicle storage layers 1a and 1b. Further, when the traveling rail member 23 is moved up and down by the elevating traveling rail device 22, when there are three or more vehicle storage layers capable of moving the movable carriage 3 with respect to each other, the movable carriages used in the respective vehicle storage layers are used. The number of 3 may be singular or plural depending on the operation method.

  The elevating traveling rail device 22 raises and lowers the traveling rail member 23 from the position of the carriage traveling rail 7a in the lowermost vehicle storage layer 1a to the height position of the carriage traveling rail in the upper desired vehicle storage layer. As long as it is possible and does not interfere with the lift device 8, the shape and structure of the lifting frame 24, the vertical dimension and arrangement of the lifting guide 25, the chain of the lifting drive mechanism 28 in the lifting frame 24 The connection position 36 may be changed as appropriate other than the illustrated one.

  Further, the lifting drive mechanism 28 of the traveling rail member 23 in the lifting traveling rail device 22 does not require a pit on the inner bottom surface of the housing 6, and the movable carriage 3 in the carriage traveling path 4 of the lowermost vehicle storage layer 1 a. For example, if there is an arrangement and configuration that does not interfere with the lift device 8, the lift frame 24 is attached to the lower side of the travel rail member 23 and is slidably attached to the lift guide 25 in the vertical direction. A lifting drive mechanism having an arbitrary configuration other than that illustrated may be employed, such as a configuration in which a toggle mechanism that switches between an extended state and a bent state is interposed between the inner bottom surface of the housing 6 and the cylinder 6.

  In the present invention, the carriage travel path 4 of the movable carriage 3 that moves in the horizontal direction in the vehicle storage layer intersects with the hoistway 9 that lifts and lowers the lift frame 13 of the lift device 8, and is arranged at the intersection. If the mechanical parking device is of a type that passes the pallet 2 for placing the vehicle to each other by moving the movable carriage 3 and the lift frame 13 so as to pass each other in the vertical direction, other than the plane reciprocation method You may apply to a mechanical parking apparatus.

  Of course, various modifications can be made without departing from the scope of the present invention.
