Description

  The present invention relates to a pallet movement restriction device capable of restricting movement of a vehicle-mounted pallet stored in a parking rack at a storage position even when a parking tower is greatly shaken during an earthquake or the like, and an elevator parking device provided with the pallet movement restriction device.

  Conventionally, general apartment houses, commercial apartment buildings, and the like are often provided with parking devices such as elevator parking devices that are attached to or incorporated in the buildings.

  Generally, in the case of the elevator type parking apparatus, a hoistway is formed in the vertical direction of a parking tower in which an exterior plate is provided on the outer surface of the steel structure, and a number of parking shelves are arranged on both sides of the hoistway. It is formed in a shape. Moreover, the entrance / exit is normally provided in the lowermost ground of the hoistway. The parking device main body of such an elevator parking device includes an elevator lifting platform that is mounted with a vehicle-mounted pallet (hereinafter simply referred to as “pallet”) and can be moved up and down along the hoistway. The elevator lift is moved up and down by a wire rope or the like, and the mounted pallet is transferred (transferred) between the elevator lift and the parking shelf by a pallet transfer mechanism provided in the elevator lift. It has become.

  In such an elevator type parking apparatus, the pallet stored in the parking rack moves laterally from the storage position of the parking rack due to vibration caused by the driving of the parking apparatus or shaking in the event of an earthquake, and protrudes into the hoistway. Various pallet lock mechanisms are provided in each parking shelf so as not to cause a problem.

  As a prior art of this kind, there is a parking shelf provided with a stopper mechanism that protrudes with a spring member toward the front in front of the pallet cross member so as to restrict the lateral movement of the stored pallet (for example, Patent Document 1).

  As another prior art, a stopper pin is provided on the lower surface of the pallet, and a fixing hook protruding by a biasing force of a spring is hooked on the stopper pin so that the pallet cannot be moved (for example, patents). Reference 2).

  Furthermore, as another prior art, there is a pallet lock mechanism filed by the present applicant. As shown in FIG. 9, the pallet lock mechanism 105 forms a recess 103 for dropping the wheel 102 (transverse roller) of the pallet 101 on the upper surface of the hoistway side end and the counter hoistway side end of the parking shelf 100. In addition, a stopper member 104 protrudes from the side of the parking rack 100 at a position slightly away from the recess 103 on the hoistway side and the counter hoistway side, and is formed on the frame member 106 that supports the wheels 102 of the pallet 101. The abutting portion 107 abuts against the stopper member 104, thereby preventing the pallet 101 from moving in the horizontal direction in the transfer direction and restraining the pallet 101 on the parking rack 100 (rail) (see Patent Document 3). ).

  By the way, in the case of an elevator-type parking apparatus, it is generally incorporated in a parking tower of a steel structure that is erected on the ground or in a building void. On the other hand, in recent years, elevator-type parking devices tend to be taller, and due to earthquakes and wind damage and wind pressure, the entire parking tower formed of the steel frame structure may sway like a bow in the upper layer even if it swings slightly on the ground. In particular, in the case of a parking tower installed in a valley of a building, it may shake greatly due to wind damage and wind pressure.

  In this way, when the upper layer of the parking tower is greatly shaken by an earthquake or wind damage wind pressure, the pallet lock mechanisms described in Patent Documents 1 and 2 are all actuated mechanisms (spring mechanisms, fixed hooks, etc.) on each parking shelf. Therefore, these operating mechanisms themselves may be damaged. Therefore, in the case of a pallet lock mechanism having such an operating mechanism, there is a risk that the parking tower will be greatly shaken and damaged, and the intended pallet lock function cannot be achieved. There is also a risk of protruding into the hoistway.

  On the other hand, in the case of the pallet lock mechanism disclosed in Patent Document 3, each parking shelf is not equipped with any operating mechanism (spring mechanism, fixed hook, etc.), and since it has a simple structure, there is little risk of damage. However, as shown in FIG. 9, when the shelf column 108 and the parking rack 100 (shelf rail) are greatly shaken in three dimensions (vertical, horizontal, and longitudinal) due to an earthquake or wind damage wind pressure, the pallet 101 is complicatedly swayed. It may be possible to float up without following. When such a lift occurs, there is a risk that the end of the frame member 106 (groove-shaped member) will be disengaged relatively upward from the stopper member 104 and the parking rack 100 and the wheel 102 may be removed from the parking rack 11. is there. If this derailment is on the hoistway 110 side, the flange 109 of the wheel 102 and the lower surface of the end of the frame member 106 ride on the stopper member 104, and eventually the pallet 101 and the mounted vehicle V move to the hoistway 110 side. There is also a risk of protruding.

  In addition, there are cases where it is desired to further restrict the movement of pallets in preparation for unexpected earthquakes in existing middle and low-rise elevator parking systems.

  Accordingly, the present invention provides a pallet movement restriction device that can reliably restrict the movement of a pallet at the storage position of the parking shelf even if a large shaking occurs in the parking tower due to an earthquake or the like, and an elevator parking device including the pallet movement restriction device. With the goal.

In order to achieve the above object, a pallet movement restriction device according to the present invention includes a lifting platform that mounts a pallet and moves up and down a vertical hoistway, and a parking that transfers and stores the pallet in the horizontal direction from the lifting platform. A pallet movement restricting device in a parking device comprising a shelf, wherein the pallet is controlled when a three-dimensional movement including vertical movement in the retracted state of the pallet occurs at an end position on the anti-hoistway side of the parking shelf. A three-dimensional movement restricting means that engages with the hoistway side end and restricts the movement of the pallet at the storage position of the parking shelf is provided . The three-dimensional movement restricting means receives an upward force acting on the pallet, and the pallet It has a lift prevention stopper that regulates the lift and horizontal movement of the pallet when it is lifted . The concept of the direction in the document of this specification and a claim is the state which turned to the front of a parking apparatus, and is made into the up-down direction, the left-right direction, this side is the front direction, and the back is the back direction. As a result, even if three-dimensional movement including vertical movement occurs on the pallet, the anti-lifting side end of the pallet and the horizontal movement are restricted by the anti-lifting stopper of the three-dimensional movement restricting means. Therefore, even if a large shaking occurs in the parking shelf when an earthquake occurs, it is possible to reliably regulate the movement of the pallet from the parking shelf storage position.

Further, the three-dimensional movement regulating means may further include a movement prevention stopper path receives a force in the horizontal direction acting on the pallet. In this way, it is possible to affect the synchronization horizontal forces acting on the pallet by movement prevention stopper.

  Further, the lifting prevention stopper includes a horizontal portion provided above the position of the parking pallet on the side opposite to the hoistway of the pallet, a stopper portion protruding in a vertical direction at the position of the horizontal portion, and the stopper portion includes The stopper portion and the engaging portion may be disposed with a predetermined gap therebetween. In this way, when a three-dimensional movement including a vertical movement occurs, if the pallet is moved upward beyond the predetermined gap, the horizontal part is restricted from moving upward, and the stopper part is engaged. It is possible to restrict other movements that act on the pallet by engaging with the part.

  The stopper part has a stopper bar extending in the vertical direction, and the engaging part has a hole part into which the stopper bar is inserted and engaged when a three-dimensional movement including a vertical movement occurs. It may be. In this way, when the three-dimensional movement including the vertical movement occurs, the stopper rod is inserted into the hole and the horizontal movement is restricted around the hole. The horizontal movement of the bar can be reliably controlled.

  Furthermore, the parking shelf may include the horizontal portion and a stopper portion, and the pallet may include the engaging portion. In this way, the parking shelf can be provided with a stopper portion that restricts movement of the pallet, and the pallet can be easily provided with an engaging portion that engages with the stopper portion. The movement restricting device can be easily provided.

  Moreover, the said movement prevention stopper may have the shelf stopper member which controls the movement to the anti- hoistway direction of a pallet in the anti-hoistway side edge part position of the said parking shelf. In this way, when three-dimensional movement including vertical movement occurs, the pallet comes in contact with the shelf stopper member at the end of the parking shelf on the side opposite to the hoistway, so that the pallet transfer direction (wheel rolling direction) The movement of the stopper portion and the engaging portion can be more reliably engaged by restricting the movement of the stopper.

  Further, the parking shelf may have a recess in which a wheel is positioned when the pallet is stored, and the shelf stopper member may be disposed on the side opposite to the hoistway near the wheel positioned in the recess. In this way, when three-dimensional movement including vertical movement occurs on the pallet, the movement of the pallet wheel in the anti-hoistway direction is restricted by the shelf stopper member, and the wheel is positioned in the recess. The storage state can be kept stable.

  On the other hand, an elevator parking apparatus according to the present invention includes an elevator lift that mounts a pallet and moves up and down a vertical hoistway, and a hierarchical parking shelf that transfers and stores the pallet in the horizontal direction from the elevator lift. The elevator type parking apparatus is provided with any one of the pallet movement restriction devices at a position on the side opposite to the hoistway of the parking shelf. As a result, even if a large shake is generated in the parking rack in the event of an earthquake or the like, and the pallet has a three-dimensional movement including a vertical movement, the end of the pallet on the side opposite to the hoistway is restricted by the three-dimensional movement restricting means. Thus, the pallet can be reliably restricted from moving from the storage position of the parking shelf. Therefore, it is possible to provide a pallet movement restricting device that functions stably as a countermeasure against shaking in the upper layer portion of an elevator parking device that tends to be higher.

  According to the present invention, even if a three-dimensional movement including a vertical movement occurs in the pallet stored by shaking the parking shelf greatly due to an earthquake or wind damage wind pressure, the pallet is moved to the storage position by the three-dimensional movement restricting means. Since the movement can be restricted, it is possible to reliably prevent the pallet from moving from the parking rack even during a large earthquake or the like.

(a), (b) is drawing which shows the modification of the three-dimensional movement control means shown in FIG. In the conventional pallet lock mechanism, it is a front view at the time of raising a pallet by a big earthquake shake.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the following embodiments, a high-rise elevator parking device standing on the ground will be described as an example.

  As shown in FIG. 1, the elevator parking apparatus 1 has a parking tower 2 in which an exterior plate is provided on the outer surface of a steel structure, and the first floor above the parking tower 2 is a platform 3. . A pit 5 is formed on the boarding floor 4 of the boarding unit 3.

  In such an elevator type parking apparatus 1, a hoistway 10 is formed in the vertical direction of the central part of the parking tower 2, and hierarchical parking racks 11 (parking parts) are provided in the vertical direction on both the left and right sides of the hoistway 10. ing. These parking shelves 11 are provided on shelf columns 13 arranged in the vertical direction. Further, the hoistway 10 is provided with an elevator hoisting table 12 for conveying the pallet 20. The elevator lift 12 is moved up and down the hoistway 10 by a wire rope 15 wound by a lift driving unit 14 provided at the upper part of the parking tower 2. On the side of the wire rope 15 opposite to the elevator, a counterweight 16 that reduces the hoisting force is provided. And the elevator raising / lowering base 12 is raised / lowered between the pit 5 of the boarding part 3 and the parking shelf 11 by the raising / lowering drive part 14, The pallet transfer means 21 (FIG. 2) mentioned later with which this elevator raising / lowering base 12 was equipped. Accordingly, the pallet 20 on which the vehicle V is mounted and the empty pallet 20 are transferred between the parking rack 11 (shelf rail) and the elevator lift 12. A parking tower 2 indicated by a two-dot chain line in FIG. 1 indicates the parking tower 2 that is greatly shaken at the time of an earthquake described later.

  As shown in FIG. 2, the pallet transfer means 21 provided in the elevator lifting / lowering base 12 has a base portion supported at the center of the elevator lifting / lowering base 12 and a tip portion rotatably supported in a horizontal plane. An arm 22, a second arm 23 having a base connected to the tip of the first arm 22 and rotatably supported in a horizontal plane, and an engagement roller 24 provided at the tip of the second arm 23 Have.

  When the pallet 20 is transferred (stored) by the pallet transfer means 21, the first arm 22 and the second arm 23 are first rotated in the direction of the pallet 20 to be transferred, and the engagement roller at the tip of the second arm 23 is moved. 24 is engaged with an engagement groove 25 provided on the lower surface of the pallet 20. The first arm 22 is turned while the second arm 23 keeps the engagement roller 24 engaged with the engagement groove 25. Thereby, the wheel 26 of the pallet 20 is made to traverse from the rail 17 of the elevator lift 12 to the parking rack 11 (shelf rail). Thereafter, the first arm 22 is turned while changing the angle of the second arm 23 so that the engaging roller 24 is detached from the engaging groove 25 of the pallet 20, and the storing operation is completed. The pallet transfer from the parking shelf 11 to the elevator lift 12 is performed in the reverse of the above operation. The pallet transfer means 21 transfers each pallet 20 between each parking shelf 11 and the elevator lift 12. The pallet transfer means 21 may be another pallet transfer means, and is not limited to this embodiment.

  And when the three-dimensional movement including the movement in the vertical direction occurs on the pallet 20 at the end position on the side opposite to the hoistway of each parking shelf 11 (the left and right end portions shown in the figure, the transfer back direction) A pallet movement restricting device 45 having a three-dimensional movement restricting means 50 for restricting the movement of the pallet 20 at the storage position of each parking shelf 11 is provided. Details of the pallet movement restricting device 45 will be described later.

  As shown in FIG. 3, the transfer of the pallet 20 by the pallet transfer means 21 provided in the elevator elevator 12 is performed as follows. First, the elevator lift 12 is stopped at the position of the predetermined parking shelf 11, and the connecting cylinder 31 is extended in the direction of the parking shelf 11 by extending the drive cylinder 35 of the elevator lift 12. As a result, the guide groove 32 of the connecting member 31 is projected along the guide roller 33, and the locking groove 34 provided at the front end of the connecting member 31 is locked to the locked roller 41 of the parking shelf 11, and thus the elevator. The elevator 12 is fixed to the parking shelf 11.

  Thereafter, the pallet 20 is moved by the pallet transfer means 21 so that the small-diameter roller portion 27 of the wheel 26 of the pallet 20 passes from the rail 17 of the elevator lift 12 to the parking shelf 11 (shelf rail) through the upper surface of the connecting member 31. ) And the pallet 20 is transferred. After the pallet 20 is transferred, the driving cylinder 35 is contracted to disengage the connecting member 31 from the parking rack 11, whereby the wheel 26 is dropped into the recess 36 formed in the parking rack 11 (two-dot chain line).

  As shown in FIG. 4, the wheel 26 of the pallet 20 includes a flange portion 29 guided by the front and rear end surfaces of the parking shelf 11, a large-diameter roller portion 28 that rolls on the parking shelf 11 (rail), The small-diameter roller portion 27 that rolls on the upper surface of the connecting member 31 of the elevator lift 12 that is engaged with the locked roller 41 of the parking shelf 11 inside the radial roller portion 28 is provided.

  When the pallet 20 stored in the parking shelf 11 is viewed from the hoistway 10 side, the large-diameter roller portion 28 of the wheel 26 supported by the frame member 37 (a groove-shaped member opened downward) is dropped into the recess 36. As a result, the frame member 37 supporting the axle 30 of the wheel 26 is lowered by a predetermined amount from the state shown in FIG. In this stored state, the lower portion of the contact portion 38 formed on the frame member 37 of the pallet 20 has a height that overlaps with the overlap dimension h5 from the upper end of the stopper member 39 that protrudes horizontally from the parking shelf 11, Even if the pallet 20 tries to move in the transfer direction, the contact portion 38 contacts the stopper member 39 and the movement in the transfer direction is restricted. As described above, when the pallet 20 is stored, the frame member 37 does not come into contact with the stopper member 39, and when the wheel 26 is dropped into the recess 36 and stored, the frame member 37 comes into contact with the stopper member 39. Depth h4]> [overlapping dimension h5].

  This configuration is a pallet lock mechanism 40 that functions as a movement prevention stopper that receives a force in the left-right direction. By this pallet lock mechanism 40, the wheel 26 dropped into the recess 36 in a small and medium-scale earthquake shakes. The movement of the pallet 20 in the left-right direction can be regulated by contacting the stopper member 39 without coming off from the place 36 (see FIG. 6).

  As shown in FIG. 5, as the three-dimensional movement restricting means 50 of the pallet movement restricting device 45, in this embodiment, the movement is prevented from receiving a force in the anti-hoistway direction acting on the pallet 20 due to seismic force or the like. It has a stopper 51 and a lift prevention stopper 52 that receives an upward force acting on the pallet 20 due to seismic force or the like. The lift prevention stopper 52 includes a vertical post 53 erected on the upper surface of the end opposite to the hoistway of the parking shelf 11, and a horizontal plate 54 which is a horizontal portion fixed to the upper surface of the vertical post 53 and extending toward the hoistway 10. A stopper rod 55 that is a stopper portion that is penetrated in a state in which a predetermined amount protrudes vertically downward from an end portion that extends to the hoistway side of the horizontal plate 54, and a frame member 37 to which the wheel 26 of the pallet 20 is attached. It has the circular hole 57 which is an engaging part opened to the anti-hoistway side end part upper surface. The movement preventing stopper 51 has a shelf stopper member 56 that protrudes in the horizontal direction from the lower portion of the vertical post 53 toward the hoistway 10 and is close to the wheel 26 located in the recess 36.

  In this embodiment, an example of the engagement portion in which the circular hole 57 is formed on the upper surface of the frame member 37 of the pallet 20 has been described. However, the circular hole 57 may be a “rectangular” or other shape hole portion. . Moreover, although the conical rubber body is employ | adopted as the said shelf stopper member 56, this shelf stopper member 56 may be another structure.

  According to such a pallet movement restricting device 45, as will be described later, when the pallet 20 is transferred in a normal state, there is a predetermined gap between the stopper bar 55 and the pallet 20, but an earthquake or When the parking rack 11 is greatly shaken by wind damage wind pressure or the like and the pallet 20 is lifted from the parking rack 11, the movement of the pallet 20 can be restricted so as not to greatly deviate from the storage position.

  As shown in FIG. 6, according to the elevator type parking apparatus 1 configured as described above, the pallet 20 in the normal state stored in the normal position of the parking rack 11 has the large-diameter roller portion 28 of the wheel 26. It is in a state of being dropped into the recess 36 of the parking shelf 11. In this state, the contact portion 38 of the frame member 37 is lowered by the overlap dimension h5 from the upper end of the stopper member 39 as described above. Therefore, the horizontal movement in the transfer direction causes the contact portion 38 to move to the stopper member 39. It abuts and is regulated. Further, in this state, the three-dimensional movement restricting means 50 of the pallet movement restricting device 45 is in a state in which the front end surface of the shelf stopper member 56 is just before or in contact with the large diameter roller portion 28 of the wheel 26. The lower end of the stopper bar 55 is located at a position separated from almost the center of the circular hole 57.

  The vertical distance relationship between the horizontal plate 54 and the frame member 37 and the vertical distance relationship between the parking rack 11 and the wheels 26 and the frame member 37 in the normal state shown in FIG. The distance h1 between the frame member and the upper surface of the frame member] <[distance h2 between the upper surface of the parking shelf (rail) and the lower end of the wheel cage or the frame member contact portion]. With such a distance relationship, even if the pallet 20 moves greatly in the vertical direction and the upper surface of the frame member 37 contacts the lower surface of the horizontal plate 54, the flange portion 29 and the contact portion 38 of the frame member 37. Is positioned below the upper surface of the parking shelf 11, so that the movement of the pallet 20 in the front-rear direction is prevented by the abutting portion 29 or the contact portion 38 of the frame member 37 contacting the parking shelf 11. . Thereby, the parking shelf 11 receives the force which acts on the front-back direction of the pallet 20 by seismic force etc.

  Further, the relationship between the lower end of the stopper bar 55 and the upper surface of the frame member 37 is set such that [gap h3 between the lower end of the stopper bar and the upper surface of the frame member]> [depth of recess h4]. With such a distance relationship, when the pallet 20 is transferred between the elevator platform 12 and the parking rack 11, the pallet movement regulating device 45 does not affect the traversal of the pallet 20, and the recess 36 is not affected. The wheel 26 can be dropped and pulled out from the recess 36.

  On the other hand, when a large earthquake occurs, the entire parking tower 2 is greatly shaken vertically and horizontally (two-dot chain line in FIG. 1), and the side opposite to the hoistway of the pallet 20 placed on the parking rack 11 is, for example, FIG. 7, the stopper member 39 provided on the parking shelf 11 is not separated from the contact portion 38 of the frame member 37 and does not perform the stopper function when it is lifted relative to the parking shelf 11. The movement restricting device 45 can restrict the movement of the pallet 20.

  That is, the stopper bar 55 enters the circular hole 57 provided in the frame member 37 of the pallet 20 that has been lifted, and the two-dimensional movement of the pallet 20 in the left and right and front and rear directions is restricted within the range of the circular hole 57 by the stopper bar 55. Is done. Further, the upper surface of the frame member 37 is brought into contact with the lower surface of the horizontal plate 54 and is prevented from being lifted further, thereby restricting the upward movement. In addition, the floating prevention by the horizontal plate 54 is prevented by a distance at which the collar portion 29 or the abutting portion 38 of the frame member 37 is not detached from the parking shelf 11 due to the relationship of [distance h1 <distance h2]. The collar 29 and the frame member 37 do not move upward from the parking rack 11, and the movement of the pallet 20 in the front-rear direction is prevented by the parking rack 11.

  Therefore, since these movement restrictions restrict | limit the pallet 20 in a big three-dimensional movement in the parking shelf 11, it can prevent reliably that the pallet 20 moves from the storage position of the parking shelf 11. FIG.

  In the three-dimensional movement restricting means 50 of the pallet movement restricting device 45 in the above embodiment, a stopper bar 55 is provided on the horizontal plate 54 and a circular hole 57 is formed in the frame member 37 of the pallet 20. These may be reversed as shown in (a). That is, the circular hole 57 may be formed in the horizontal plate 54 and the stopper rod 55 may be provided in the frame member 37.

  In the above-described embodiment, the vertical post 53 and the horizontal plate 54 are separate members. However, as shown in FIG. 8B, these may be a single post 60 formed by bending a plate material. Furthermore, in the above embodiment, the stopper rod 55, which is a stopper portion, is constituted by a bolt 58 and a nut 59, but the stopper portion has a protruding member 61 suspended from the lower surface of the horizontal portion by welding or the like, Other configurations may be used.

  As described above, according to the elevator parking apparatus 1, the pallet movement restriction having the three-dimensional movement restriction means 50 at the end of the parking shelf 11 on the side opposite to the hoistway without providing any operating mechanism on the parking shelf 11 side. By providing the device 45, even if the parking tower 2 is greatly shaken by an earthquake or the like and the pallet 20 is moved in a three-dimensional manner including a vertical movement, the three-dimensional movement regulating means 50 causes the pallet 20 to be on the side opposite to the hoistway. Therefore, it is possible to reliably prevent the pallet 20 (and the mounted vehicle V) from being derailed from the parking rack 11 or protruding from the hoistway 10. That is, even if a large shake occurs in the parking tower 2 due to an unexpected large earthquake or wind damage wind pressure, the pallet 20 can be reliably prevented from moving from the storage position.

  The three-dimensional movement restricting means 50 includes a simple and inexpensive unit member including a configuration of a vertical post 53 provided on the parking shelf 11 and a stopper bar 55 provided on the horizontal plate 54, and the pallet 20. Since it can be implemented by providing a circular hole 57 by a simple process applied to the frame member 37, the existing elevator parking device (particularly, middle and low-rise elevator parking devices) can be easily modified and provided. Therefore, it is also possible to easily attach the pallet movement restricting device 45 as an unexpected earthquake countermeasure in the existing elevator parking device.

  In the above-described embodiment, the recess 36 is provided in the parking shelf 11 (shelf rail) to drop the wheel 26 of the pallet 20 and the lateral movement of the pallet 20 is prevented by the stopper member 39 provided on the parking shelf 11. However, the pallet locking mechanism 40 may have other configurations and is not limited to the above embodiment.

  The above-described embodiment shows an example, and various modifications can be made without departing from the gist of the present invention. The present invention is not limited to the above-described embodiment.

  The pallet movement restriction device according to the present invention can be used in an elevator-type parking device having a parking tower that tends to be high-rise.
