Description

  The present invention relates to a parking device pallet employed in various three-dimensional parking devices such as an elevating parking device, an elevating / lowering parking device, and an elevator parking device.

  Conventionally, as a three-dimensional parking apparatus configured to be capable of parking a plurality of automobiles, a plurality of parking apparatus pallets (hereinafter simply referred to as pallets) for placing automobiles, and a pallet moving apparatus for moving each pallet, The thing with is provided.

  Such a three-dimensional parking apparatus is configured to move a car to an empty space together with the pallet by moving the pallet up and down, and moving the pallet in accordance with a pattern for moving the pallet. As a pallet moving device, a lifting device that lifts and lowers or a combination of a traversing device and a lifting device is employed.

  The pallet is arranged on the pallet main body in which a pair of wheel mounting parts for mounting the left and right wheels of the automobile are formed on both sides of the central part in the left-right width direction (hereinafter simply referred to as the width direction) and on the lower surface side of the pallet main body. And a reinforcing beam extending in the width direction.

  The pallet body is manufactured by connecting a plurality of bent plate materials or bending a single plate material, and the direction in which the pair of wheel mounting portions are orthogonal to the width direction (hereinafter referred to as front and rear) The vehicle can be loaded and unloaded while being at the ground level. That is, the pallet body is formed such that a pair of wheel mounting portions extend in the front-rear direction in order to ensure smooth movement in the front-rear direction of the left and right wheels of the automobile.

  And a pallet main body is formed so that a pair of wheel mounting part may become a lower position than the center part of the width direction. That is, the bending strength in the front-rear direction is increased by forming the pallet body into a mountain fold shape in the width direction or by projecting the center portion in the width direction.

  The pallet main body having the above-described configuration has a traveling roller attached to the both ends in the width direction in the width direction with a gap wider than the distance between the left and right wheels of the vehicle, It is configured such that supports such as vertically moving struts and ropes are connected. As a result, the pallet is provided so as to move up and down and traverse in a state in which the support positions set in the width direction are wider than the distance between the left and right wheels of the automobile.

  Reinforcing beams are used to ensure the bending strength in the width direction of the pallet, and are generally composed of square steel pipes or sections defined by JIS standards and fixed to the lower surface of the pallet body by welding or the like. Is done.

Thereby, the bending strength of the pallet in the front-rear direction and the width direction is obtained, and the pallet can sufficiently withstand even a heavy vehicle (see Patent Document 1, for example).
JP-A-6-66038

  By the way, as described above, the pallet having the above-described configuration is supported by a pair of wheel mounting portions because support positions (both side end portions, etc.) that are set wider than the interval between the left and right wheels of the vehicle in the width direction are supported. When the left and right wheels of an automobile are placed, a large bending moment acts between the left and right wheels of the automobile (between a pair of wheel mounting parts), so the reinforcing beam is bent sufficiently at the part corresponding to the center of the pallet body. Strength will be required.

  Then, the strength of the reinforcing beam is set based on the bending strength at the center of the pallet body, but standardized square steel pipes and shaped steels have a uniform cross-sectional shape over the entire length in the longitudinal direction. For this reason, when these are used as reinforcing beams, both ends in the width direction are excessively strong. Therefore, the reinforcing beam has an excessive configuration at both ends in the width direction, and there is a problem that the weight of the pallet itself becomes unnecessarily heavy.

  Then, this invention makes it a subject to provide the pallet for parking apparatuses reduced in weight, ensuring the required bending strength of the left-right width direction in view of such a situation.

  A pallet for a parking device according to the present invention was made to solve the above-mentioned problem, and a pallet main body formed with a pair of wheel mounting portions on which both left and right wheels of an automobile are mounted on both sides of a central portion in the left-right width direction, The pallet main body is formed by processing the plate material so that the pair of wheel mounting portions are positioned lower than the center portion. In the parking apparatus pallet, the reinforcing beams are arranged in a front-rear direction orthogonal to the left-right width direction, and include a pair of vertical ribs whose upper ends are spaced apart from each other and whose lower ends are connected directly or indirectly, Each upper end of the vertical rib is formed so as to continuously or intermittently extend in the left-right width direction with respect to at least the central portion of the pallet main body and the lower surfaces of the pair of wheel mounting portions. Wheel mounted Characterized in that it is continuously or intermittently connected to the lateral width direction with respect to the lower surface of the parts.

  According to the parking apparatus pallet having the above configuration, since the pallet main body is formed by processing the plate material so that the pair of wheel mounting portions are positioned lower than the central portion, the upper surface and the lower surface of the pallet main body. As a result, the pair of wheel placement portions are positioned lower than the center portion on the lower surface side of the pallet main body. Therefore, each upper end of the pair of vertical ribs is formed so as to continuously or intermittently extend in the left-right width direction with respect to at least the center portion of the pallet body and the lower surfaces of the pair of wheel mounting portions, and the pallet body The height in the vertical direction of the central part in the lateral direction of the reinforcing beam (a pair of vertical ribs) is connected continuously or intermittently in the lateral direction to the lower surface of the central part and the pair of wheel mounting parts. Becomes higher than the portion corresponding to the pair of wheel mounting portions. As a result, the section modulus of the central part in the left-right width direction of the pallet is increased, and the bending action in the left-right width direction can be sufficiently countered even if the thickness of the pair of vertical ribs is reduced.

  Therefore, the reinforcing beam can be reduced in weight by the thickness of the pair of vertical ribs. Further, each upper end of the pair of vertical ribs is formed so as to continuously or intermittently extend in the left-right width direction with respect to at least the center portion of the pallet main body and the lower surfaces of the pair of wheel mounting portions, thereby reinforcing beams ( The pair of vertical ribs) is lower in height on both sides than the central part in the left-right width direction, so that it does not become excessive in strength at both ends of the reinforcing beam, and this can also reduce the weight. it can.

  In the pallet having the above configuration, the upper ends of the pair of vertical ribs whose lower ends are connected directly or indirectly are continuous in the left-right width direction with respect to the central portion of the pallet body and the lower surfaces of the pair of wheel mounting portions. As a result of the connection between the upper ends of the pair of vertical ribs being closed by the center of the pallet body or the pair of wheel mounting portions, the cross-sectional shape effective for twisting around the axis of the reinforcing beam It becomes. That is, as a result of the pair of vertical ribs and the pallet main body being integrated and the cross-sectional shape in the front-rear direction is a non-annular (polygonal cylindrical shape, etc.) closed cross section, the portion can sufficiently resist twisting. Become.

  As one aspect of the parking apparatus pallet according to the present invention, the reinforcing beam includes a rib connecting portion that connects the lower ends of the pair of vertical ribs, and the pair of vertical ribs are provided with an interval from the upper end to the lower end. Also good. In this way, the section modulus of the portion that becomes the closed section can be increased, and the bending strength is further increased.

  As another aspect of the parking apparatus pallet according to the present invention, the reinforcing beam is formed by bending a single plate material so as to form a pair of vertical ribs whose lower ends are connected directly or indirectly. May be. If it does in this way, a reinforcing beam (a pair of vertical ribs) can be produced integrally, and it can be made excellent in strength. Further, since complicated work such as welding is not required in producing the reinforcing beam, it is also effective from the viewpoint of manufacturing efficiency.

  As another aspect of the parking apparatus pallet according to the present invention, the central portion of the pallet main body in the left-right width direction stands upward from the boundary with each wheel mounting portion, and is opposed to the left-right width direction with an interval. A pair of standing wall portions and a connection portion connecting the upper ends of the pair of standing wall portions, and the reinforcing beam has at least the upper ends of the pair of vertical ribs along the lower surfaces of the connection portion and the wheel mounting portion. It may be formed as follows. In this way, the bending strength in the front-rear direction of the pallet body can be increased, and the bending strength at the central portion in the left-right width direction can be locally increased, making the strength superior. be able to.

  As still another aspect of the parking apparatus pallet according to the present invention, it is preferable that the reinforcing beam is provided at a position corresponding to at least the front and rear wheels of the automobile parked on the pallet body. If it does in this way, the load of the parked car can be received with a reinforcement beam, and it can be prevented that a bending action of the horizontal direction is made unnecessarily in a pallet main part.

  In this case, the pallet main body includes a pair of reinforcing portions extending in the front-rear direction at both end portions in the left-right width direction, and each reinforcing portion includes an upright portion that stands upward from a boundary with the wheel placement portion, and an upright portion. It consists of an extending part that extends outward in the left-right width direction from the upper end of the part, and a hanging part that is suspended from the tip of the extending part, and the reinforcing beam corresponds to the front end part of the pallet body The vertical rib at least on the front end side of the pallet main body is provided with a closed portion that closes the open portion that is surrounded by the upright portion, the extended portion, and the hanging portion and that opens toward the front. It may be provided at both ends.

  If it does in this way, the bending strength of the front-back direction of a pallet main body can be raised with a pair of reinforcement part. Further, by providing the reinforcing beam at the front end of the pallet body, the load when the automobile enters and exits can be received by the reinforcing beam, and the bending due to the entry and exit of the automobile can be sufficiently resisted. And when the standing part, the extension part, and the hanging part are formed on the pallet body, an open part surrounded by these and opened forward is formed, so that it is opened when the driver gets on and off the pallet. There is a risk that the foot will be fitted into the portion, but such danger can be eliminated by closing the open portion with the closing portion of the vertical rib.

  As described above, according to the pallet for parking apparatus according to the present invention, it is possible to achieve an excellent effect that the weight is reduced while ensuring the necessary bending strength in the left-right width direction.

Is formed.

  In this embodiment, since the pallet main body 10 is divided into the center part 101 which protruded upwards, and a pair of wheel mounting part 100a, 100b, the 2nd reinforcement beam 30 is the width direction ( (Longitudinal direction of the second reinforcing beam 30), a second reinforcing portion 30a corresponding to the central portion 101, a pair of wheel mounting portions 100a, 100b, and a pair of second reinforcing portions 30b corresponding to the reinforcing portions 104, 104. , 30b. Since the lower ends of the vertical ribs 300, 300 are formed substantially straight in the longitudinal direction of the second reinforcing beam 30, the upper ends thereof are along the lower surfaces of the connection portion 103 and the pair of wheel mounting portions 100a, 100b as described above. Thus, the height of the second reinforcing portion 30a (vertical ribs 300, 300) in the vertical direction is set higher than that of the second reinforcing portions 30b, 30b (vertical ribs 300, 300). And the upper end of the vertical ribs 300 and 300 of the 2nd reinforcement part 30a is formed so that it may incline forward and downward toward the both sides from a center so that the lower surface of the connection part 103 may be corresponded. And as for the 2nd reinforcement part 30a, the upper end part interposed between a pair of standing wall parts 102 and 102 is set shorter than the space | interval of a pair of standing wall parts 102 and 102 in the width direction. A gap is formed between the second reinforcing beam 30 (the second reinforcing portion 30a) and the standing wall portions 102 and 102.

It forms so that it may incline forward and downward toward the edge part of a longitudinal direction from the boundary. The pair of second reinforcing portions 30 b and 30 b reach the vicinity of both ends in the width direction of the pallet main body 10.

  Since the second reinforcing beam 30 is provided at a position corresponding to the front end portion of the pallet main body 10 as described above, at least one vertical rib 300 on the front end side of the pallet main body 10 (the second rib according to the present embodiment). In the reinforcing beam 30, the pair of vertical ribs 300, 300 is an open portion that is surrounded by the open portions 105, the extended portions 106, and the hanging portions 107 at both ends of the pallet body 10. Blocking portions 305 that block the portion 109) are provided at both ends in the width direction. The closing portion 305 is formed to protrude upward so as to correspond to the shape of the opening portion 109, and the upper end of the closing portion 305, which is the upper end of both end portions of the vertical ribs 300, 300, is an extension portion. 106 and the upright portion 105 are welded. 6 is provided so that one vertical rib 300 on the front end side of the pallet main body 10 is aligned with the front end of the pallet main body 10, the second reinforcing beam 30 is One of the vertical ribs 300 may be provided so as to be offset from the front end of the pallet main body 10 by the predetermined distance (for example, welding allowance).

  As shown in FIG. 8, the second reinforcing beam 30 according to the present embodiment bends a plate material (hereinafter referred to as a developed plate material) 30 ′ having a predetermined shape (a shape in which the longitudinal ribs 300 and 300 and the rib connecting portion 301 are developed). Is formed. The unfolded plate member 30 ′ is a rib-shaped region 301 ′ to be a rib connecting portion 301, and rib forming to be longitudinal ribs 300, 300 formed so as to be continuous on both sides in a direction orthogonal to the longitudinal direction of the band-shaped region 301 ′. The region 300 ′, 300 ′ is provided, and the boundary (straight boundary) between the strip-shaped region 301 ′ and the rib forming regions 300 ′, 300 ′ is set as a planned processing line LP to be bent.

  Accordingly, the developed plate member 30 ′ is formed so that both ends, which are the upper ends of the longitudinal ribs 300, 300 in the short direction of the strip-shaped region 301 ′, correspond to the shape of the lower surface side of the pallet main body 10. As a result, the developed plate member 30 ′ is bent along the planned processing line LP, so that the rib forming regions 300 ′ and 300 ′ are raised and become the vertical ribs 300 and 300 which face each other and have substantially straight lower ends. The lower ends of 300 and 300 become the second reinforcing beam 30 having a U-shaped cross section connected to the band-like region (rib connecting portion 301) (see FIGS. 5 and 6).

  Returning to FIG. 1 and FIG. 2, the pallet 1 according to the present embodiment is at least one of the pair of wheel mounting portions 100 a and 100 b (in the present embodiment, so that the automobile can be parked in an appropriate arrangement). A vehicle stopper 40 for the rear wheel of the automobile is fixed to the upper surface of one wheel mounting portion 100a). As the vehicle stopper 40, various forms can be employed, but in the present embodiment, a resin molded body molded in an L shape in plan view is employed, and a bolt is attached to the pallet body 10. It is fixed.

  As shown in FIG. 1, the elevating device 5 includes a support 50 for supporting the pallet 1 and a drive unit (not shown) for moving the support 50 in the vertical direction.

  The pillars 50 are made of section steel or the like, and four are provided so as to correspond to the arrangement of the first reinforcing beams 20 and 20 (brackets 108) of the pallet 1. That is, four support columns 50 are erected, two of which are arranged so as to correspond to one of the first reinforcing beams 20 on the front side of the pallet 1, and the remaining two are located behind the pallet 1. It arrange | positions so as to correspond to the other 1st reinforcement beam 20 in the side. And each support | pillar 50 ... the bracket 108 ... of the pallet 1 is screw-fixed. In the parking device P according to the present embodiment, since the pallets 1 are arranged in a plurality of stages in the vertical direction, a plurality of pallets 1 (in the present embodiment, three pallets 1...) It is fixed at intervals in the direction.

  Various types of drive units can be employed, and the drive unit according to the present embodiment includes a hydraulic cylinder and a hydraulic unit that expands and contracts the hydraulic cylinder. It is moved (lifted / lowered) in the longitudinal direction (vertical direction).

  The multistage elevating parking apparatus P is installed after an underground pit (not numbered) is formed at the installation location. Such an underground pit is formed so that the pallet 1 below the pallet 1 can be accommodated when the uppermost pallet 1 is located at the ground level. Accordingly, the multistage elevating type parking apparatus P moves the support 50 in the vertical direction by the elevating apparatus 5 so that any one of the plurality of pallets 1 provided in a multistage manner is set to the ground level (incoming / exiting the car). It is designed to be located at a level that is possible. In addition, since the multistage elevating type parking apparatus P only raises / lowers the multistage pallet 1, as shown in FIG. 1, a plurality of multistage elevating parking apparatuses P are arranged in parallel in the width direction according to the number of cars to be parked.

  As described above, when the pallet 1 is moved up and down or the automobile is moved in and out of the pallet 1 at the ground level, the pallet 1 is bent in the front-rear direction and the width direction. However, the bending action in the front-rear direction is countered by the cross-section in the width direction of the pallet 1 (pallet body 10).

  On the other hand, the bending action in the width direction is countered by the cross section in the front-rear direction of the pallet 1 (the pallet main body 10, the first reinforcing beam 20, and the second reinforcing beam 30).

  In the pallet 1 according to the present embodiment, as shown in FIGS. 3 and 5, the pallet main body 10 is formed by processing the plate material so that the pair of wheel mounting portions 100 a and 100 b are positioned lower than the central portion 101. As a result, the upper surface and the lower surface of the pallet body 10 are in a front-back relationship. As a result, on the lower surface side of the pallet body 10, the pair of wheel mounting portions 100 a and 100 b are positioned lower than the center portion 101. .

  Therefore, the upper ends of the pair of vertical ribs 200, 200, 300, 300 are continuously or intermittently along the width direction with respect to the center portion 101 of the pallet body 10 and the lower surfaces of the pair of wheel mounting portions 100a, 100b. The upper end of the pallet body 10 is connected continuously or intermittently in the width direction to the central portion 101 of the pallet body 10 and the lower surfaces of the pair of wheel mounting portions 100a, 100b, and a pair of longitudinal ribs 200, 200 , 300, 300 so that the lower ends thereof extend substantially straight in the width direction, the first reinforcing beam 20 (the pair of vertical ribs 200, 200) and the second reinforcing beam 30 (the pair of vertical ribs 300, 300). 300), the height in the vertical direction is higher than the portion corresponding to the pair of wheel mounting portions 100a and 100b. As a result, the section modulus of the central part in the width direction of the pallet 1 is increased, and even if the thickness of the pair of longitudinal ribs 200, 200, 300, 300 is reduced, the bending action in the width direction can be sufficiently countered. Become.

  Therefore, in the 1st reinforcement beam 20 and 20 and the 2nd reinforcement beam 30, since the thickness of a pair of vertical rib 200,200,300,300 can be made thin, these can be reduced in weight. Moreover, in the 1st reinforcement beam 20 and the 2nd reinforcement beam 30, each upper end of a pair of vertical rib 200,200,300,300 is on the lower surface of the center part 101 of a pallet main body 10, and a pair of wheel mounting part 100a, 100b. On the other hand, the first reinforcing beam 20 (the pair of vertical ribs 200, 200) and the second reinforcing beam 30 (the pair of vertical ribs 300, 300) are formed so as to be continuously or intermittently along the width direction. Since the heights on both sides thereof are lower than the central portion in the width direction, both side portions of the first reinforcing beam 20 and the second reinforcing beam 30 do not become excessive in strength, thereby reducing the weight. be able to.

  And the pallet 1 of the said structure is the center part 101 of the pallet main body 10 in each upper end of a pair of vertical rib 200,200,300,300 by which the lower end was connected in the 1st reinforcement beam 20 and the 2nd reinforcement beam 30. In addition, since it is continuously or intermittently connected in the width direction to the lower surfaces of the pair of wheel mounting portions 100a and 100b, as shown in FIGS. 4 and 6, the pair of longitudinal ribs 200, 200, 300, As a result of the state where the upper end of 300 is closed by the central portion 101 of the pallet main body 10 or the pair of wheel mounting portions 100a and 100b, the cross-sectional shape is effective against twisting. That is, as a result of the pair of vertical ribs 200, 200, 300, 300 and the pallet main body 10 being integrated, the cross-sectional shape in the front-rear direction becomes a non-annular (polygonal cylindrical shape, etc.) closed cross section. It will be enough to compete.

  Thus, the pallet 1 according to the present embodiment is lightened while securing the necessary torsional strength and bending strength in the width direction by configuring the reinforcing beams 20 and 30 as described above.

  Each of the first reinforcing beams 20, 20 and the second reinforcing beam 30 includes rib connecting portions 201, 301 that connect lower ends of the pair of vertical ribs 200, 200, 300, 300, and the pair of vertical ribs 200. , 200, 300, 300 are provided with an interval from the upper end to the lower end, the section modulus of the portion that becomes the closed section is increased, and the bending strength is further increased.

  And the pallet 1 which concerns on this embodiment forms a pair of vertical rib 200,200,300,300 by which the 1st reinforcement beam 20,20 and the 2nd reinforcement beam 30 connected the lower ends directly or indirectly. As described above, since a single plate member 20 ′, 30 ′ is formed by bending, a pair of longitudinal ribs 200, 200, 300, 300 can be integrally manufactured, and the strength is excellent. Can be. Moreover, since complicated work such as welding is not required, it is also effective from the viewpoint of manufacturing efficiency. In particular, the upper ends of the vertical ribs 200, 200, 300, 300 are arranged along the central portion 101 of the pallet body 10 and the lower surfaces of the wheel mounting portions 100 a, 100 b, so that the reinforcing beams 20, 30 are assembled when the pallet 1 is assembled. By placing the bent plate members 10a, 10b on the vertical ribs 200, 200, 300, 300, the arrangement thereof is determined, and the assembly work can be made efficient.

  As shown in FIGS. 3 and 5, the central portion 101 in the width direction of the pallet main body 10 stands upward from the boundary with each wheel mounting portion 100 a, 100 b and faces the width direction with an interval. The pair of upright wall portions 102 and 102 and a connection portion 103 that connects the upper ends of the pair of upright wall portions 102 and 102, and the first reinforcing beams 20 and 20 and the second reinforcing beam 30 are paired with each other. Since the upper ends of the vertical ribs 200, 200, 300, 300 are formed along the lower surfaces of the connection portion 103 and the wheel mounting portions 100a, 100b, the bending strength in the front-rear direction of the pallet body 10 can be increased. Furthermore, the bending strength at the center in the width direction can be locally increased, and the strength can be further improved.

  Further, as shown in FIG. 2, the first reinforcing beams 20, 20 are provided at positions corresponding to the front and rear wheels TFR, TRR, TFL, TRL of the automobile parked on the pallet main body 10, so that the parked automobile Can be received by the first reinforcing beams 20, 20, and the pallet body 10 can be prevented from causing an unnecessary bending action in the width direction.

  The pallet body 10 includes a pair of reinforcing portions 104, 104 extending in the front-rear direction at both end portions in the width direction, and the reinforcing portions 104, 104 are directed upward from the boundary with the wheel mounting portions 100a, 100b. The upright portion 105, the extended portion 106 that extends outward in the width direction from the upper end of the upright portion 105, and the hanging portion 107 that is suspended from the tip of the extended portion 106. Therefore, the bending strength in the front-rear direction of the pallet main body 10 can be increased by the pair of reinforcing portions 104 and 104.

  In addition to the first reinforcing beams 20 and 20, the second reinforcing beam 30 is provided at a position corresponding to the front end portion of the pallet body 10, so that the wheels TFR, TRR, TFL, TRL when the automobile enters and exits the vehicle. Can be received by the second reinforcing beam 30, and can sufficiently resist the load (bending) associated with the entry / exit of the automobile. Further, as shown in FIG. 5, one vertical rib 300 on the front end side of the pallet main body 10 closes the open portion 109 that is surrounded by the standing portion 105, the extending portion 106, and the hanging portion 107 and is opened forward. Since the closing portions 305 are provided at both ends in the width direction, it is possible to eliminate the danger that the feet will fit into the opening portion 109 when a driver or the like gets on and off the pallet body 10. .
