Description

  The present invention relates to a pit type three-dimensional parking apparatus.

  As an example of the configuration of a conventional pit type three-dimensional parking apparatus, there is a pit type parking apparatus described in Patent Document 1, for example. This conventional multi-story parking apparatus includes a pallet lifting body composed of a plurality of pallets arranged vertically in a pit formed at a predetermined depth from the ground surface of the vehicle. A pair of front and rear suspension chains wound around a drive shaft are bridged around the lower part of the pallet lifting body, as in the pit type parking apparatus described in Patent Document 2, for example. Then, the pallet lifting / lowering body is moved up and down by feeding and winding the suspension chain by the drive shaft, and the designated pallet is moved to the position on the ground surface.

  In the pit, a plurality of columns to which a drive shaft and the like are attached are installed around the pallet lifting body. In the upper part of the column, a road plate is provided along the front and rear direction of the pallet at a position corresponding to the ground surface, and on the pallet by the end in the width direction of the pallet moved to the ground surface and the road plate.

  By the way, in the conventional pit type parking apparatus as described above, it is necessary to set the position of the drive shaft higher than the ground surface due to the structure of the lifting system using the suspension chain. Therefore, the height of the road plate provided on the support column is made higher than the ground surface by the amount that the drive shaft is raised from the ground surface. Also, from the viewpoint of securing rigidity, the end of the pallet is raised from the parking surface of the vehicle, and the height thereof is substantially the same as the road plate. However, in such a configuration, there is a problem that the passage protrudes from the parking surface of the vehicle, and it is difficult to get on and off and walk. In addition, there is a problem that tires get on due to the difference between the inner wheels when the vehicle is loaded and unloaded.

  On the other hand, for example, a method of setting the position of the drive shaft to a position lower than the ground surface by lowering the position of the suspension chain on the pallet is conceivable. However, in this case, since a thickness is generated in the lower structure of the pallet lifting body, deeper pits are required. Therefore, the existing pit must be recreated, and it is difficult to replace the existing multilevel parking device.

  The present invention has been made to solve the above problems, and provides a three-dimensional parking apparatus capable of flattening a passage composed of a pallet and a road plate with respect to the ground surface without increasing the depth of a pit. The purpose is to provide.

  In order to solve the above-mentioned problems, a multi-story parking apparatus according to the present invention includes a frame formed by standing a pair of left and right front columns and rear columns in a pit formed at a predetermined depth from the ground surface of a vehicle. A pallet lifting body composed of a plurality of pallets arranged in the vertical direction on the inner side of the frame body, and the pallet lifting and lowering is spanned to the lower part of the pallet lifting body on the rear side of the position of the car stopper in each pallet A suspension chain for lifting the body, a drive motor for rotating the drive shaft around which the end of the suspension chain is wound, and moving the desired pallet of the pallet lifting body to the ground surface by feeding and winding the suspension chain; A multi-story parking apparatus comprising a road plate that is disposed in the front-rear direction of the pallet at the top and forms a passage by cooperating with the pallet moved to the ground surface. Motor, than the installation position of the car stops at each pallet is arranged on the rear side, Michiban is a front side of the installation position of the bollard, and characterized in that it has a ground plane substantially flush.

  In this three-dimensional parking apparatus, the position of the suspension chain is set behind the installation position of the vehicle stop on each pallet, and the drive shaft for winding the suspension chain and the drive motor for driving the drive shaft are both located behind the installation position of the vehicle stop. It is said. For this reason, there is no drive shaft in front of the vehicle stop installation position, so even if the position of the drive shaft is set higher than the ground surface, the height of the road plate provided on the frame body is reduced. It can be configured to be substantially flush with the upper surface. Therefore, in this multilevel parking device, the passage constituted by the pallet and the road plate can be flat with respect to the ground surface without increasing the depth of the pit.

  In addition, a pair of left and right balance chains that hold the horizontal state of the pallet lifting body is bridged under the pallet lifting body, and both ends of the balance chain are connected to the front end of the lowest pallet in the pallet lifting body and A sprocket that is fixed to the rear end and that engages the middle portion of the balance chain is preferably provided at the top and bottom of the front strut and the position corresponding to the rear end of the pallet at the bottom of the pit.

  When the suspension chain is arranged only at the rear side of the installation position of the car stopper, it is considered that the horizontal balance in the front-rear direction of the pallet lifting body is lowered as compared with the case where the suspension chain is respectively disposed before and after the pallet lifting body. . Therefore, the horizontal balance of the front-back direction of a pallet raising / lowering body can be maintained by providing the above balance chains. Moreover, since the sprocket which meshes with the intermediate part of the balance chain is provided in the support column and the pit, the structure of the pallet is not complicated and the flattening of the passage is not hindered.

  In addition, a bracket for passing the suspension chain to the left and right is arranged on the lowermost pallet in the pallet lifting body, and the bracket is fixed to the upper surface side of the lowermost pallet at a position behind the car stopper. preferable. In this case, since the vertical length of the pallet lifting / lowering body is suppressed by providing the bracket on the upper surface side of the lowermost pallet, the pit depth can be more reliably maintained.

  According to the present invention, it is possible to make the passage formed by the pallet and the road plate flat with respect to the ground surface without increasing the depth of the pits.

The frame 3 is a road provided between a front strut 4 and a rear strut 5 erected in a pair on the left and right at the front and rear of the pit P, and between the top of the front strut 4 and the top of the rear strut 5. It is comprised by the board 21. FIG. A pallet elevating body 6 is disposed in a space surrounded by the frame body 3.

  The pallet elevating body 6 includes a plurality of (three) pallets 7 on which the vehicle is placed, and front and rear pallet columns 8 and 9. That is, the pallet lifting / lowering body 6 has an upper pallet 7a, a middle pallet 7b, and a lower pallet 7c, and each of these pallets 7a, 7b, 7c is formed by a pair of left and right front pallet columns 8 and a rear pallet column 9. It is connected in three stages.

  The pallet 7 includes a face plate 11 and a hollow beam 12 having a rectangular cross section that reinforces the face plate 11. The upper surface of the face plate 11 is a parking surface on which the vehicle can be parked, and a vehicle stop 13 for restricting the entry position of the vehicle is provided. Further, the beam 12 is fixed to both sides of the face plate 11 with the upper face thereof being substantially flush with the upper face of the face plate 11. Thereby, flattening of the upper surface of the pallet 7 is realized. In addition, the shaping | molding of the face plate 11 and the beam 12 which comprises the pallet 7 uses the steel plate which has high rust prevention ability, such as a galvanized steel plate. In addition, instead of using a hollow member having a rectangular cross section, the beam 12 is bent downward at the end of the pallet 7 into a L-shaped cross section by pressing or the like, and combined with a L-shaped press material facing the bent portion. May be formed.

  A suspension chain 14 is suspended from the lower part on the rear side of the pallet lifting body 6. The pallet lifting / lowering body 6 is suspended from the bottom surface of the pit P to a predetermined height by the suspension chain 14. Further, a pair of left and right balance chains 15, 15 are bridged on the side of the pallet lifting body 6. The balance chains 15 and 15 maintain a horizontal balance when the pallet elevating body 6 moves up and down.

  On the upper surface side of the lower pallet 7, on the rear side of the installation position of the car stopper 13, as shown in FIG. Both end portions of the suspension chain bracket 16 extend to the positions of the left and right beams 12 of the lower pallet 7, and suspension chain sprockets 17 with which the suspension chain 14 meshes are respectively supported.

  Further, as shown in FIG. 2, the front end 18 of the left and right beams 12 of the lower pallet 7 has a balance chain front bracket 18 to which one end of the balance chain 15 is fixed in correspondence with the position of the front support column 4. Is provided. Further, at the rear end portions of the left and right beams 12, a balance chain rear bracket 19 to which the other end portion of the balance chain 15 is fixed is provided at a position corresponding to the corner portion of the pallet 7. On the lower side of the rear end of the left and right beams 12 of the lower pallet 7 and on the lower side of the rear end of the rear bracket 19 for the balance chain, avoid interference with a driven shaft 43 and the rear sprockets 44, 44 described later. For this purpose, a notch (see FIG. 3) is formed.

  On the other hand, a road plate 21 is provided between the top of the front column 4 and the top of the rear column 5. The road plate 21 extends substantially flush with the ground surface G in front of the installation position of the car stopper 13 in the pallet 7, and cooperates with the pallet 7 moved to the ground surface G by raising and lowering the pallet lifting body 6. The passage 22 is formed by the action. It is preferable that the road plate 21 corresponding to the passage 22 and the beam 12 of the pallet 7 are colored differently from the central portion of the pallet 7. If it carries out like this, the position confirmation at the time of entering / exiting of a vehicle will become easy.

  Next, an elevating mechanism of the pallet elevating body 6 will be described. As shown in FIG. 2, the unit parking apparatus 2 includes a drive motor 31, a drive shaft 32, the above-described suspension chain 14 and balance chains 15 and 15.

  The drive motor 31 has a drive sprocket 33, and the main body portion of the drive motor 31 is fixed to the top of the rear column 5 on one side of the frame 3 on the rear side of the installation position of the car stopper 13 in the pallet 7. Yes. The drive shaft 32 extends to a position directly below the main body portion of the drive motor 31 and is rotatably supported at the top of the rear column 5.

  The position of the drive shaft 32 is set higher than the ground surface G because the pallet lifting body 6 is raised by the suspension chain 14 until the lower pallet 7 reaches a height equivalent to the ground surface. A cover 34 (see FIG. 4) is attached to the drive motor 31 and the drive shaft 32 that protrude from the ground surface G. Thereby, safety is ensured so that contact with a person does not occur. Further, since the cover 34 becomes a target when the vehicle enters the pallet 7, an effect of preventing the vehicle from protruding from the pallet 7 can be expected.

  An interlocking sprocket 35 is fixed to the rear end portion of the drive shaft 32, and an endless chain 36 is bridged between the drive sprocket 33 and the interlocking sprocket 35. A lifting sprocket 37 is fixed to the front end portion of the drive shaft 32 so as to correspond to the position of the suspension chain sprocket 17. One end side of the suspension chain 14 is wound around the lifting sprocket 37.

  The suspension chain 14 is passed through the suspension chain bracket 16 on the upper surface side of the lower pallet 7 via the suspension chain sprocket 17 and is spanned in the width direction of the lower pallet 7. The other end side of the suspension chain 14 is fixed to the top of the rear column 5.

  On the other hand, one end and the other end of the balance chain 15 are respectively fixed to the front bracket 18 and the rear bracket 19 for the balance chain provided at the front and rear ends of the beam 12 in the lower pallet 7. Has been. With respect to the configuration of the balance chain 15, balance chain front sprockets 41 and 42 are provided above and below the front column 4, respectively, and the bottom surface of the pit P extends in the width direction along the rear end of the lower pallet 7. An existing driven shaft 43 is provided. Balance chain rear sprockets 44 and 44 are provided at both ends of the driven shaft 43 so as to correspond to the positions of the balance chain rear bracket 19. The driven shaft 43 synchronizes the phases of the rear sprockets 44 and 44 for the balance chain and makes the feed amounts of the balance chains 15 and 15 provided on the left and right of the pallet lifting body 6 the same so that the pallet lifting body 6 Contributes to maintaining the horizontal balance in the horizontal direction when moving up and down.

  As a result, the intermediate portion of the balance chain 15 is wound around the balance chain front sprocket 41 on the upper portion of the front column 4 and is stretched along the front column 4 in the vertical direction. Then, the intermediate portion of the balance chain 15 is wound around the balance chain front sprocket 42 below the front support column 4 and is bridged in the front-rear direction of the pallet 7 near the bottom surface of the pit P, and then the balance chain rear side It is wound around the sprocket 44 and is bridged in the vertical direction toward the rear bracket 19 for the balance chain. Further, the other balance chain 15 that forms a pair with the balance chain 15 is disposed in a symmetrical relationship (see FIG. 2).

  According to the configuration of the multi-story parking apparatus 1 as described above, when the drive sprocket 33 is rotated by the drive motor 31, the rotational force is transmitted to the drive shaft 32 through the endless chain 36, and the suspension associated with the rotation of the drive shaft 32 is performed. The pallet lifting / lowering body 6 moves up and down by feeding and winding the chain 14. By moving the desired pallet 7 to the loading / unloading position (that is, the position of the ground surface G) by moving the pallet lifting / lowering body 6 up and down, the vehicle can be loaded into and unloaded from the pallet 7.

  Here, in this multilevel parking device 1, the position of the suspension chain 14 is on the rear side of the installation position of the car stopper 13 on the pallet 7, and the drive shaft 32 that winds the suspension chain 14 and the drive that drives the drive shaft 32. Both the motor 31 and the motor stop 31 are located behind the installation position of the vehicle stopper 13. For this reason, since the drive shaft 32 does not exist in front of the installation position of the vehicle stop 13, the road plate provided in the frame body 3 even if the position of the drive shaft 32 is set higher than the ground surface G. The height of 21 can be configured to be substantially flush with the ground surface G.

  Therefore, in this multilevel parking device 1, the pallet 7 and the road plate 21 are configured when the pallet 7 moves to the position of the ground surface G as shown in FIG. 4 without increasing the depth of the pits P. The passage 22 to be made can be made flat with respect to the ground surface G. As a result, in the multi-story parking device 1, the passage 22 does not protrude, so that the problem that it is difficult to get on and off and walk and the problem that the tires get on due to the difference in the inner wheel when the vehicle enters and leaves the vehicle are solved. Is possible.

  Here, as described above, when the suspension chain 14 is disposed only on the rear side of the installation position of the vehicle stop, the pallet lifting body 6 can be compared with the case where the suspension chain 14 is disposed before and after the pallet lifting body 6. It is conceivable that the horizontal balance in the front-rear direction decreases. On the other hand, in the multilevel parking device 1, the horizontal balance in the front-rear direction of the pallet lifting body 6 can be maintained by the left and right balance chains 15. Therefore, the safety when the pallet elevating body 6 moves up and down is ensured. Further, since the sprockets 41, 42, and 44 that mesh with the intermediate portion of the balance chain 15 are provided in the front support column 4 and the pit P, the configuration of the pallet 7 is not complicated, and flattening of the passage 22 is hindered. It never happens.

  Furthermore, in the multi-story parking device 1, the suspension chain bracket 16 is fixed to the upper surface of the lower pallet 7 at a position behind the car stopper 13. In this case, since the vertical length of the pallet elevating body 6 is suppressed as compared with the case where the suspension chain bracket 16 is provided on the bottom surface side of the lower pallet 7, the depth of the pits P can be more reliably maintained.
