Abstract

<P>PROBLEM TO BE SOLVED: To provide a multistory parking system capable of absorbing an impact load of a pallet in the loading and unloading of a vehicle, without imposing a burden on an ascent/descent guiding mechanism. <P>SOLUTION: In this multistory parking system 1, an abutting member 12 is provided in the position, corresponding to a ground surface G, of the vehicle M. When the pallet 7 swings along with the loading and unloading of the vehicle M and moves to a rear side, the abutting member 12 separated from an inner wall W of a pit P abuts on a stopper member 13 which is positioned on the front side of the abutting member 12. In this way, since not the inner wall W but the abutting member 12 is an object abutting on the stopper member 13, the abutting member 12 and the stopper member 13 can abut on each other with a higher degree of accuracy than in the case where the stopper member 13 abuts on the inner wall W with no secured flatness. Consequently, the impact load of the pallet 7 in the loading and unloading of the vehicle M can be absorbed without imposing the burden on the ascent/descent guiding mechanism. <P>COPYRIGHT: (C)2011,JPO&amp;INPIT

Description

  The present invention relates to a multi-story parking apparatus.

  In the pit elevating type three-dimensional parking apparatus provided with a pallet that is lifted and lowered between a plurality of parking portions arranged in the vertical direction, the pallet easily swings when the vehicle enters and leaves. In particular, the impact of the wheels coming into contact with the car stop when entering the warehouse is large, and the pallet swinging due to this impact may cause an abnormality in the sensor that detects the elevation in the multi-story parking device, or the malfunction of the elevation guide mechanism. It is done. Therefore, a multi-story parking device provided with a swing prevention device that prevents the swing of the pallet is known (for example, see Patent Document 1).

  In addition, a multi-story parking device is provided with a stopper made of metal, for example, at the rear end of the pallet so that when the pallet swings, the stopper is brought into contact with the wall to prevent transmission of impact load to the lifting guide mechanism. Is also known.

  By the way, in the pit where the multi-story parking apparatus is provided, a clearance is required so that the stopper and the wall do not come into contact with each other when the underground pallet is normally raised and lowered. However, it is difficult to ensure the flatness of the walls forming the pits, and the accuracy is, for example, about ± 5 cm. Depending on the flatness, there may be a problem that the stopper does not function effectively. In such a case, an impact load to be transmitted by the stopper is transmitted to the pallet lifting guide mechanism, and the impact load is absorbed by the lifting guide mechanism. Therefore, in the three-dimensional parking apparatus having the conventional stopper, a configuration for absorbing the impact load received by the pallet has not been sufficiently considered.

  The present invention has been made to solve the above-described problem, and provides a three-dimensional parking apparatus capable of absorbing the impact load of a pallet when a vehicle is loaded and unloaded without imposing a burden on the lifting guide mechanism. Objective.

  In order to solve the above problems, a multi-story parking apparatus according to the present invention 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 a vehicle. A three-dimensional parking device, a contact member disposed at a position corresponding to the ground surface and spaced from the inner wall of the pit facing the rear end side of the pallet, and a contact when the pallet is raised and lowered to the ground surface And a stopper member fixed to the rear end of each step pallet so as to be positioned on the front side of the member.

  This three-dimensional parking apparatus is provided with a contact member at a position corresponding to the ground surface of the vehicle, and is separated from the inner wall of the pit when the pallet swings and moves rearward as the vehicle enters and exits. The abutting member and the stopper member located on the front side of the abutting member abut. As described above, the contact member is not the wall but the contact member is contacted with the stopper member, so that the contact member and the stopper are highly accurate compared to the case where the stopper is contacted with the wall whose flatness is not ensured. Can be brought into contact with each other. As a result, the impact load applied to the pallet when the vehicle is loaded and unloaded is reliably transmitted from the stopper to the contact member, so that it is possible to prevent the impact load from being absorbed by the lift guide mechanism. Therefore, the impact load of the pallet at the time of entering / exiting the vehicle can be absorbed without imposing a burden on the lifting guide mechanism.

  In addition, a notch is formed at the corner of the rear end of the pallet, and the abutting member and the stopper member face each other within an area defined by the notch as viewed from the pallet lifting / lowering direction. It is preferable. With such a configuration, the contact member and the stopper come into contact with each other at a position entering the inside of the pallet with respect to the rear end portion of the pallet, so that the clearance between the pallet and the inner wall can be reduced.

  The stopper member is fixed to the rear end portion of each step pallet so as to protrude from the rear end portion of the pallet to the inner wall side, and the rear end portion of each step pallet is connected to the rear end portion of each step pallet. A cover for closing the gap with the inner wall is preferably provided. With such a configuration, the contact member and the stopper member can be reliably contacted. Further, the clearance between the pallet and the inner wall can be reduced by the cover.

  Further, it is preferable that the pallet is fixed with a car stopper, and the fixing portion of the stopper member is located on the same line as the fixed position of the car stopper in the front-rear direction of the pallet. With such a configuration, it is possible to efficiently transmit the impact load when the vehicle wheel comes into contact with the vehicle stop to the stopper. Thereby, it is possible to more reliably absorb the impact load of the pallet when the vehicle enters and exits.

  Further, a fixing member that protrudes from the inner wall of the pit in the front-rear direction of the pallet is further provided, and the contact member is detachably attached to the fixing member so that the position of the pallet in the front-rear direction can be adjusted. preferable. With such a configuration, the clearance between the contact member and the stopper member can be adjusted.

  Hereinafter, an embodiment of a multilevel parking device according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a diagram showing an outline of a multi-story parking apparatus according to an embodiment of the present invention. As shown in the figure, the multi-story parking device 1 is provided in a pit P formed at a predetermined depth from the ground surface G where the vehicle M enters and exits. The three-dimensional parking apparatus 1 includes a frame body 2, a pallet lifting body 3, a lifting drive mechanism (not shown), and the like. In the following description, the entry / exit side of the vehicle M will be described as the front side.

  The frame body 2 is composed of a front support column 4 and a rear support column 5 erected on the left and right sides of the pallet lifting body 3, and front and rear beams 6 installed between the top of the front support column 4 and the top of the rear support column 5. It is configured. A rectangular parallelepiped space surrounded by the front column 4 and the rear column 5 forms a space for the unit parking device, and the pallet lifting / lowering body 3 is arranged in the space.

  The pallet lifting / lowering body 3 includes an upper pallet 7, a middle pallet 8, and a lower pallet 9, and parking portions for storing vehicles are arranged in three stages in the vertical direction of the frame 2. That is, in a state where the entire pallet lifting / lowering body 3 is housed in the pit P, the upper space of the upper pallet 7 becomes the upper parking portion, the upper space of the middle pallet 8 becomes the middle parking portion, and the upper pallet 9 The space is the lower parking area. The upper pallet 7, middle pallet 8, and lower pallet 9 are integrally connected by a pallet column 10. The pallet elevating body 3 can be displaced up and down by an elevating drive mechanism, and is moved up and down between a plurality of parking portions.

  The raising / lowering drive mechanism of the pallet raising / lowering body 3 is a well-known thing, For example, it is as follows, although detailed description is abbreviate | omitted. The pallet elevating body 3 is supported by two front and rear roller chains spanned in the width direction on the lower surface of the lower pallet 9 so as to be movable up and down, and is disposed in the vicinity of the upper portion of the rear column 5 on one side with respect to the pallet elevating body 3. The chain sprocket mechanism is actuated by the raising / lowering movement of the drive motor unit thus moved up and down in the pit P.

  As shown in FIGS. 2 and 3, the multi-story parking apparatus 1 includes an impact absorbing structure 11. 2 is a view of the shock absorbing structure 11 in the multi-story parking apparatus 1 as viewed from above, and FIG. 3 is a view of the shock absorbing structure 11 in the multi-story parking apparatus 1 as viewed from the front. The impact absorbing structure 11 is configured to absorb the impact load received by each of the pallets 7 to 9 when the vehicle M enters and exits.

  The shock absorbing structure 11 includes a contact member 12 and a stopper member 13 provided on each of the pallets 7 to 9. 2 and 3, the upper pallet 7 is shown, but the other pallets 8 and 9 have the same configuration.

  The contact member 12 is an L-shaped member having a plate-like fixing portion 12a and a plate-like protruding portion 12b. The contact member 12 is made of, for example, a steel material. The contact member 12 is disposed on the rear end side of the pit P at a position corresponding to the ground surface G of the vehicle M, that is, at a height position when the upper pallet 7 is positioned on the ground surface G.

  Specifically, the contact member 12 is fixed to the fixing member 14. The fixing member 14 is a member that supports and fixes the contact member 12, and is provided below the rear end portion of the road plate R disposed so as to sandwich the pallet lifting body 3. The fixing member 14 is fixed to the inner wall W of the pit P facing the rear end side of the upper pallet 7 and has a protruding portion 14 a that protrudes from the inner wall W toward the front side in the front-rear direction of the upper pallet 7. A plurality of bolt fastening holes (not shown) are provided in the protruding portion 14 a along the front-rear direction of the upper pallet 7.

  The contact member 12 is fixed to the protruding portion 14a of the fixing member 14 so that the protruding portion 12b is separated from the inner wall W and protrudes toward the upper pallet 7 side. The protrusion 14a and the fixing part 12a are fixed by bolt fastening by screwing a bolt into a bolt fastening hole of the protrusion 14a. By selecting a hole into which the bolt is screwed, the position of the contact member 12 in the front-rear direction can be adjusted.

  The stopper member 13 is a U-shaped member having a rectangular top portion 13a, a bottom portion 13b substantially parallel to the top portion 13a, and a web portion 13c connecting the top portion 13a and the bottom portion 13b. The stopper member 13 is made of steel, for example. At one end of the stopper member 13, a plate-like contact plate 13 d having a length dimension larger than that of the web portion 13 c is provided so as to close the end surface. The contact plate 13d is a member that contacts the protruding portion 12b of the contact member 12. As shown in FIG. 2, the stopper member 13 having such a configuration is provided in a notch portion 15 formed at a corner portion of the rear end portion 7 d of the upper pallet 7.

  Here, as shown in FIGS. 2 and 3, the upper pallet 7 includes a placement portion 7a on which the vehicle M is placed, a side member 7b that rises from both sides in the width direction of the placement portion 7a, It includes a flange portion 7c that protrudes outward from the side member 7b. Therefore, the above-described notch portion 15 is formed in the flange portion 7 c of the upper pallet 7.

  As shown in FIG. 2, the stopper member 13 moves the web portion 13 c to the side so that the contact plate 13 d faces the inner wall W in the region defined by the notch portion 15 when viewed from the up-and-down direction of the upper pallet 7. In a state along the member 7b, the side member 7b is fastened by two bolts. Further, a vehicle stopper 16 that is in contact with a wheel of the vehicle M is fastened to the side member 7b by two bolts in front of the stopper member 13. Therefore, the fixing part of the stopper member 13 and the vehicle stopper 16 is located on the same line.

  As shown in FIG. 2, the contact member 12 and the stopper member 13 having the above-described configuration are disposed within the region defined by the notch 15 when the upper pallet 7 is positioned on the ground surface G. It is mutually opposed so that 13 may become a front side. That is, the protrusion 12 b of the contact member 12 is shorter than the width dimension of the notch 15. The clearance between the protruding portion 12b and the stopper member 13 is about the thickness of the protruding portion 12b, and is smaller than the clearance between the rear end portion 7d of the upper pallet 7 and the inner wall W. .

  Next, the effect of the shock absorbing structure 11 in the multi-story parking apparatus 1 will be described.

  FIG. 4 is a diagram illustrating an impact absorbing structure in a conventional multi-story parking apparatus. As shown in FIG. 4, in the conventional multi-story parking device 20, the stopper 21 is provided at the rear end 22 a of the pallet 22, and when the pallet 22 swings when the vehicle is loaded and unloaded, the stopper 21 and the inner wall W Is configured to transmit the impact load received by the pallet 22 to the inner wall W. In such a configuration, when the pallet 22 is raised and lowered, a certain clearance is required so that the inner wall W and the stopper 21 do not contact each other.

  However, when the flatness of the inner wall W is not ensured, the stopper 21 and the inner wall W come into contact with each other when the pallet 22 swings if a certain clearance is secured so that the stopper 21 and the inner wall W do not contact each other. Therefore, there is a risk that the stopper 21 does not function effectively. Thereby, the impact load received by the pallet 22 is transmitted to the lifting guide mechanism and the like and absorbed. As a result, it is conceivable that a problem occurs in the lifting guide mechanism and the like, and therefore there is a need to strengthen the lifting guide mechanism.

  On the other hand, in the multi-story parking apparatus 1 according to the present embodiment, as shown in FIGS. 2 and 3, the contact member 12 is provided at a position corresponding to the ground surface G of the vehicle M, so When the upper pallet 7 swings and moves to the rear side with the delivery, the protruding portion 12b of the contact member 12 spaced from the inner wall W of the pit P and the stopper member 13 positioned on the front side of the contact member 12 And abut. As described above, the contact member 12 is made to contact the stopper member 13 instead of the inner wall W, so that the stopper member 13 is brought into contact with the inner wall W where flatness is not ensured. The contact member 12 and the stopper member 13 can be brought into contact with each other.

  As a result, the impact load applied to the upper pallet 7 when the vehicle M is loaded and unloaded is reliably transmitted from the stopper member 13 to the contact member 12, so that an impact load is applied to the elevation guide mechanism. It can be prevented from being absorbed in the guide mechanism. Therefore, it is possible to absorb the impact load of each pallet 7 to 9 when the vehicle M is loaded and unloaded without imposing a burden on the lifting guide mechanism.

  Further, a notch portion 15 is formed in the flange portion 7c of the rear end portion 7d of the upper pallet 7, and the contact member 12 and the stopper member 13 are the notch portions 15 when viewed from the raising and lowering direction of the upper pallet 7. Since they are opposed to each other within the defined area, the contact member 12 and the stopper member 13 come into contact with each other at a position entering the inside of the upper pallet 7 with respect to the rear end portion 7 d of the upper pallet 7. The other pallets 8 and 9 have the same configuration. Accordingly, the clearance between the pallets 7 to 9 and the inner wall W can be reduced as compared with the case where the contact member 12 is arranged without providing the notch 15 in the pallet 7. 7 and the inner wall W can be prevented from being fitted, and safety can be improved. Moreover, the shock absorbing structure 11 can be provided without obstructing the parking space of the three-dimensional parking apparatus 1.

  Moreover, since the fixed part of the stopper member 13 is located on the same line as the fixed part of the car stopper 16 in the front-rear direction of each pallet 7 to 9, the impact load when the wheel of the vehicle M comes into contact with the car stopper 16 is applied. It can be efficiently transmitted to the stopper member 13. Thereby, it becomes possible to absorb the impact load of each pallet 7-9 at the time of loading / unloading of the vehicle M more reliably.

  Furthermore, the fixing member 14 which has the protrusion part 14a which protrudes in the front-back direction of each pallet 7-9 from the inner wall W of the pit P is provided, and the contact member 12 can adjust the position with respect to the front-back direction of each pallet 7-9. Thus, since it attaches to the protrusion part 14a of the fixing member 14 so that attachment or detachment is possible, the clearance between the contact member 12 and the stopper member 13 can be adjusted.

  The present invention is not limited to the above embodiment. For example, in the said embodiment, as shown in FIG.2 and FIG.3, although the impact-absorbing structure 11 was provided in the one side of the multi-story parking apparatus 1, the same structure may be provided in the other side.

  In the above-described embodiment, the stopper plate 13 is fixed to the side member 7b so that the contact plate 13d faces the inner wall W in the region defined by the notch 15 when viewed from the up-and-down direction of the upper pallet 7. For example, it may be attached as shown in FIG. As shown in FIG. 5, the clearance between the inner wall W and the rear end portion 7e of the pallet 7A is smaller than the clearance between the rear end portion 7d of the pallet 7 and the inner wall W described above. That is, the length of the pallet 7A in the front-rear direction is shorter than that of the pallet 7 described above. The stopper member 13 is attached so as to protrude from the rear end portion 7e of the pallet 7A toward the inner wall W side. A plate-like cover C for closing the gap is attached between the rear end 7e of the pallet 7A and the inner wall W. The cover C is attached along the rear end 7e of the pallet 7A so as not to interfere with the stopper member 13. The length dimension of the cover C in the front-rear direction is set so as not to contact the inner wall W when the contact member 12 and the stopper member 13 are in contact.

  Even in the case of adopting the configuration as described above, the stopper member 13 is made to contact the stopper member 13 on the inner wall W where the flatness is not ensured by making the contact member 12 contact the stopper member 12 instead of the inner wall W. Compared with the case of contact, the contact member 12 and the stopper member 13 can be reliably contacted with high accuracy. Further, by attaching the cover C and closing the gap between the rear end portion 7e of the pallet 7A and the inner wall W to reduce the clearance, for example, it is possible to prevent the foot from being fitted between the pallet 7A and the inner wall W.

  Moreover, in the said embodiment, although the contact member 12 is attached to the protrusion part 14a of the fixing member 14 so that attachment or detachment is possible, the contact member 12 is the front-and-rear beam 6 (refer FIG. 1) installed on the front end reference | standard. It may be formed integrally. Even in this case, the contact member 12 and the stopper member are fixed by changing the mounting position in the front-rear direction between the front-rear beam 6 and a beam-fixing member (not shown) that is fixed to the inner wall W and supports the front-rear beam 6. 13 can be adjusted.

  Moreover, in the said embodiment, although the protrusion part 12b of the contact member 12 was made into plate shape, the shape as shown, for example in FIG. 6 may be sufficient. As shown in FIG. 6, in the contact member 12A, the protrusion 12c has a trapezoidal cross section. When such a configuration is adopted, for example, even when each pallet 7-9 comes into contact with the contact member 12A when the pallets 7-9 are raised and lowered, each protrusion 12c of the contact member 12A has each Ascending and descending can be continued without the pallets 7 to 9 being caught.

  Moreover, in the said embodiment, although the member which contact | abuts the contact member 12 in the stopper member 13 was made into the plate-shaped contact board 13d, the shape as shown, for example in FIG. 7 may be sufficient. As shown in FIG. 7, the stopper member 13 </ b> A has a contact portion with the contact member 12 that is a cylindrical contact bar 13 f. When such a configuration is adopted, for example, even when the stopper member 13A comes into contact with the contact member 12 when the pallets 7 to 9 are moved up and down, the contact rod of the stopper member 13A is brought into contact with the contact member 12. Ascending / descending can be continued without catching 13f.

  Moreover, it replaces with the contact stick 13f shown in FIG. 7, and the wheel made rotatable in the front-back direction of the pallets 7-9 may be attached. When such a configuration is adopted, for example, even when the stopper member comes into contact with the contact member 12 when the pallets 7 to 9 are moved up and down, the wheels of the stopper member are not caught by the contact member 12. The ascent and descent can be continued.

  Moreover, in the said embodiment, although the contact member 12 is attached to the protrusion part 14a of the fixing member 14 so that attachment or detachment is possible, you may attach as shown, for example in FIG. As shown in FIG. 8, the projecting portion 12d of the contact member 12B is fixed to the inner wall W with, for example, anchor bolts via a plurality (three in FIG. 8) of spacers S. The protruding portion 12d has a trapezoidal cross section. Moreover, the spacer S should just be a cushioning thing, for example, is rubber | gum. By changing the thickness (number of sheets) of the spacer S, the position of the contact member 12B in the front-rear direction can be adjusted. When such a configuration is adopted, the impact load received by the pallet 7 can be directly transmitted to the inner wall W. Further, by using, for example, rubber for the spacer S, it is possible to take measures against sound and vibration.
