Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a lifting device for a parking facility. More specifically, for example, in a parking facility having a range in which vehicle accommodation means such as pallets are arranged in two stages of an upper stage and a lower stage with a space in the middle of the parking space, the upper and lower vehicle accommodation means are individually provided. The present invention relates to a lifting device for moving up and down to the intermediate space.
[0002]
[Prior art]
As the parking facility, for example, those disclosed in Japanese Utility Model Publication No. 55-14682, Japanese Utility Model Publication No. 7-32776, Japanese Patent Application Laid-Open No. 7-62908, and the like are known.
[0003]
As shown in FIG. 9, these parking facilities 51 are provided with pallets 52 for accommodating vehicles A in three rows of upper, middle, and lower and a plurality of rows in the parking space. The front of M is configured as an entrance E of the vehicle A. The number of pallets 52b in the middle stage M is set to be at least one less than the number of rows, and can be moved in the horizontal direction. Further, the pallet 52a in the upper stage U is moved up and down between the upper stage U and the middle stage M in the parking space, and the pallet 52c in the lower stage L is raised and lowered between the middle stage M and the lower stage L in the parking space. ing.
[0004]
With such a configuration, the middle pallet 52b is traversed to the left and right, and the upper pallet 52a is lowered or the lower pallet 52c is lifted into the empty middle M space so that a vehicle entering from the entrance E is desired. The vehicle A is accommodated in the pallet 52 and the vehicle A on the desired pallet 52 is exited from the doorway E.
[0005]
In general, each of the middle pallets 52b has a front end edge and a rear end edge slidably engaged with a guide rail G disposed on the inner wall surface of the parking space, and can be traversed along the guide rail G. ing. Further, the upper pallet 52a and the lower pallet 52c are moved up and down by a chain suitably hung on a sprocket disposed at an appropriate position. In this case, a specific sprocket is driven to rotate by an electric motor, and the chain is rotated or pushed and pulled.
[0006]
[Problems to be solved by the invention]
Since any of the above techniques uses a rotational drive source such as an electric motor, vibration and noise become a problem.
[0007]
In particular, in the lifting device disclosed in Japanese Utility Model Publication No. 7-32776, the chain is freely suspended by the weight of the engagement tool attached to the end thereof. Therefore, when the drive sprocket is operated from a state where the chain is slack, a time lag occurs at the start of the movement of the chain until the slack is completely removed.
[0008]
On the other hand, a mechanism that uses hydraulic cylinders to directly lift and lower pallets to eliminate vibration and noise problems is also known, but it is necessary to install expensive hydraulic cylinders for each pallet, which increases equipment costs. The problem of increased maintenance frequency arises.
[0009]
It is an object of the present invention to provide an elevating device that avoids vibration and noise by using at least one linear drive means, and further realizes reduction in equipment cost, reduction in maintenance frequency, and elimination of the time lag. Yes.
[0010]
[Means for Solving the Problems]
The lifting device of the present invention is
A parking space, upper and lower housing means for housing a vehicle, which are vertically movable in the parking space, and which can move up and down; a fixed pulley disposed in the upper part of the parking space; The first pulley disposed in the upper housing means, the second pulley disposed in the lower housing means, the engaging pulley that can be engaged and disengaged so as to support the upper housing means from below, and both the housings Flexible transmission means for vertically moving the means; linear drive means for moving the engagement pulley in the vertical direction; and locking means for stopping and fixing at least the upper storage means in the raised position. And
The transmission means has one end fixed to the parking space portion, engages at least the engagement pulley from below and suspends it, then engages at least the fixed pulley from above, and then at least the first pulley. The two pulleys are engaged from below and suspended, and at least the first pulley is engaged from above, and the other end is fixed to the parking space.
[0011]
With this configuration, the transmission means is set to a length that hardly causes slack in the state of the reference position where the upper stage accommodation means is in the upper stage in the parking space and the lower stage accommodation means is in the lower stage in the parking space. . Then, with the upper housing means fixed to the upper stage by the locking means, if the engaging pulley is separated from the upper housing means by the linear drive means and moved up and down, the transmission means moves to raise and lower the lower housing means. . At that time, the transmission means is tensioned by the driving force of the rectilinear drive means via the engagement pulley and the weight of the lower housing means, and does not sag.
[0012]
Even when the lower housing means is located at the lower end, the transmission means hardly sags. That is, if the locking means is released, the linear drive means can be lowered and raised while supporting the upper stage accommodating means via the engaging pulley engaged with the upper stage accommodating means. At this time, since the engaging pulley and the first pulley of the upper housing means move up and down together, the transmission means hardly sag. That is, there is no time lag for the start of movement of the storage means because the transmission means on the storage means side to be lifted and lowered does not sag.
[0013]
In this way, the upper and lower housing means can be moved up and down separately by one linear drive means. In addition, because of the straight drive means, it is possible to suppress vibration and noise that are likely to be generated by the rotary drive means.
[0014]
As the linear drive means, a hydraulic cylinder, a linear motion mechanism using a screw mechanism, or the like can be adopted.
[0015]
The fixed pulley, the first pulley, the second pulley, the engaging pulley, and the transmission means are arranged on both the left and right sides of the housing means, and rod members that rotatably support the engaging pulleys are arranged on both sides. If this rod member is configured to move up and down by the linear drive means, the storage means can be moved up and down while maintaining the left and right balance by one linear drive means. In addition, this is possible with a simple configuration.
[0016]
Further, it is preferable that a double speed mechanism that is moved up and down by the linear drive means is interposed between the engagement pulley and the linear drive means. The double speed mechanism is composed of an endless rotating member and a pair of pulleys arranged to tension the rotating member up and down from the inside, and a part of the rotating member is fixed to the parking space. This is possible by fixing the other part to the engaging pulley. In this way, the vertical movement stroke of the housing means is such that the rotation stroke of the rotation member is added to the vertical movement stroke of the linear movement drive means, so that a short stroke linear movement drive means can be employed. Alternatively, the storage means can be raised and lowered at double speed.
[0017]
The lifting mechanism provided with this double speed mechanism is also arranged on both the left and right sides of the accommodating means in the same manner as described above, the left and right double speed mechanisms are supported on both sides by the bar members, and the bar members are moved up and down by the linear drive means. If comprised in this way, a accommodation means can be moved up and down, maintaining the left-right balance with one linear drive means.
[0018]
Still another lifting device of the present invention is:
A parking space, upper and lower housing means for housing a vehicle, which are vertically movable in the parking space, and which can move up and down; a fixed pulley disposed in the upper part of the parking space; A first pulley disposed in the upper housing means, a second pulley disposed in the lower housing means, an engaging pulley that can be engaged and disengaged so as to support the upper housing means from below, and both the housings A flexible transmission means for moving the means up and down separately, a linear drive means capable of moving the transmission means in the vertical direction, and a lock means for stopping and fixing the upper storage means at least in the raised position. And
The transmission means has one end fixed to the parking space portion, engages at least the engaging pulley from below and suspends it, then engages at least the first fixed pulley from above, and then at least Engage the second pulley from below and suspend it, then engage at least the first pulley from above and the other end is fixed to the parking space,
The straight drive means is composed of a drive cylinder that moves a portion of the transmission means between the fixed pulley and the second pulley in the vertical direction.
[0019]
This lifting device also has the same effect as that of the lifting device of the present invention except that the drive stroke of the drive cylinder is almost doubled.
[0020]
A sprocket wheel, roller, pulley, or the like can be selected as the above pulley, and a chain, a wire rope, or the like can be selected as the transmission means.
[0021]
DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EMBODIMENTS Embodiments of the lifting device of the present invention will be described with reference to the accompanying drawings.
[0022]
FIG. 1 is a perspective view schematically showing an embodiment of the lifting device of the present invention in a state where it is in a traverse reference position. FIG. 3A is a side view schematically showing a main part of the lifting device of FIG. 1 that has lowered the upper pallet from the traverse reference position of FIG. 1 to the middle position, and FIG. 3B is a lifting device. FIG. 6 is a side view schematically showing a state where the lower pallet is raised to the middle position.
[0023]
The elevating device described below is an elevating device that can also be applied to the parking facility 51 of FIG. 9 described above. Of course, as shown in FIG. 9, the number of columns in the pallet is not limited to three, but may be one or more.
[0024]
FIG. 1 shows a state where the upper pallet 2 is in the upper position U in the parking space S and the lower pallet 3 is in the lower position L in the parking space S. In this state, for example, a middle pallet (not shown) in an adjacent row can traverse to reach an empty space (hereinafter also referred to as a middle position) M between the upper pallet 2 and the lower pallet 3. Therefore, the state of the pallets 2 and 3 shown in FIG. 1 is also referred to as a traverse reference position.
[0025]
The lifting device 1 shown in FIG. 1 is arranged in a pair of left and right forms in the back (rear part) of the upper pallet 2 and the lower pallet 3 in the parking space S opposite to the vehicle entrance E. In the drawing, each pallet 2 and 3 is shown in a flat plate shape for easy understanding, but an actual pallet is bent to form a groove for wheel guidance. In the parking space S, left and right pulleys 4 are fixed above the vicinity of the rear edge of the upper pallet 2 at the upper position. This pulley is referred to as a fixed pulley 4. Further, an engaging bar 5 that can be engaged from below is disposed in a floating state at the rear edge of the upper pallet 2, and an engaging pulley 6 is rotatably attached to both left and right ends of the engaging bar 5. (See FIG. 2). The tip of the rod 7a of the hydraulic cylinder 7 fixed to a part of the parking space S is fixed to a substantially central portion of the engagement rod 5. The engagement rod 5 is moved up and down by the expansion and contraction of the rod 7a. Therefore, the hydraulic cylinder 7 supports a part of the weight of the upper pallet 2. A guide member for guiding the vertical movement of the engagement rod 5 may be provided. For example, a boss portion or shaft (not shown) of each engagement pulley 6 is projected outward, and a guide rod having a concave cross section with which the boss portion or shaft is slidably engaged is provided outside the engagement pulley 6. And so on. First pulleys 8 are disposed at both left and right ends near the rear edge of the upper pallet 2, and second pulleys 9 are disposed at both left and right ends near the rear edge of the lower pallet 3.
[0026]
Further, a chain 10 as a transmission means is hung around these pulleys 4, 6, 8 and 9. That is, one end of the chain 10 is attached above the pallet 2 (which may be a wall surface or a beam) at the upper position U in the parking space S, and then engaged with the engagement pulley 6 from below, and then the fixed pulley. 4 is engaged from above, then is engaged with the second pulley 9 of the lower pallet 3 from below to suspend the lower pallet 3, and then is engaged with the first pulley 8 of the upper pallet 2 from above. The other end is attached near the lower end of the middle position M of the parking space S.
[0027]
FIG. 2 shows an engagement mechanism between the engagement rod 5 and the upper pallet 2. 2A is a side view of the engagement rod 5, and FIG. 2B is a cross-sectional view taken along the line II-II in FIG. 2A. A hook 11 spaced from the left and right protrudes from the rear edge of the upper pallet 2, and the engaging bar 5 engages with the downward engaging portion 11 a of the hook 11 from below. Engagement pulleys 6 are attached via bearings 12 in the vicinity of both ends of the engagement rod 5 (only one end is shown in FIG. 2B). The tip of the rod 7a of the hydraulic cylinder is fixed to the substantially central portion of the engagement rod 5.
[0028]
Further, as shown in FIG. 1, an upper stage locking device 13 that disables the lowering of the upper stage pallet 2 located there is provided at the upper stage position U. The upper locking device 13 is configured to be driven to swing between an operating position where the stopper arm 13a is engaged with the lower surface of the upper pallet 2 and a non-operating position where the engagement is released.
[0029]
In the present embodiment, the upper lock device 13 is also used as a fall prevention device for the upper pallet 2. Therefore, the upper locking device 13 is disposed at a position slightly below the normal ascending drive stop position of the upper pallet 2, and even if the chain 10 is broken or a brake failure occurs, the upper pallet 2 is prevented from dropping. It is made to catch by 13a.
[0030]
With this configuration, the upper pallet 2 and the lower pallet 3 are moved up and down as shown in FIG.
[0031]
In order to lower the upper pallet 2 from the traverse reference position shown in FIG. 1 to the middle position shown in FIG. 3A, the stopper arm 13a of the upper lock device 13 is driven to swing from the operating position to the non-operating position. The engagement rod 5 is lowered while receiving the weight of the upper pallet 2 by the hydraulic cylinder 7. Then, the upper pallet 2 is lowered to the middle position M by the dead weight of the upper pallet 2 and the engagement pulley 6 is pulled down and the chain 10 pulls down the first pulley 8 (FIG. 3A). During this time, the lower pallet 3 remains stationary at its lower end due to its own weight, and no slack is generated in the chain 10.
[0032]
In order to return the upper pallet 2 from the middle position to the upper position U in FIG. 1, the rod 7a of the hydraulic cylinder may be extended from the state of FIG. Then, the upper pallet 2 is pushed up to the upper position U via the engagement bar 5 engaged with the lower pallet (FIG. 1). When the upper locking device 13 is operated, the upper pallet 2 is positioned at a regular ascending stop position slightly above the upper pallet 2, so that no load is applied to the stopper arm 13 a of the upper locking device 13. Similarly, no load is applied when the stopper arm 13a is retracted to the non-operating position. In addition, there is no slack in the chain 10 during the operation. In the traverse reference position of FIG. 1, the chain 10 has no play portion and is used effectively.
[0033]
Next, in order to raise the lower pallet 3 to the middle position M as shown in FIG. 3B from the traversing reference position of FIG. 1, the hydraulic cylinder 7 with the stopper arm 13a of the upper locking device 13 in the operating position. The engagement rod 5 may be pulled down by By doing so, first, the upper pallet 2 starts to be lowered by its own weight together with the engagement rod 5, but the upper pallet 2 is received by the stopper arm 13a at a slightly lowered position. Accordingly, since the lowering of the first pulley 8 is also prevented, the portion engaged with the second pulley 9 of the chain 10 is pulled up and the lower pallet 3 is raised. Further, the engagement rod 5 is released from the upper pallet 2 by the hydraulic cylinder 7 and is lowered. As a result, the lower pallet 3 is raised to the middle position M and stopped by stopping the hydraulic cylinder 7. To return the lower pallet 3 from the middle position M to the lower position L shown in FIG. 1, the rod 7a of the hydraulic cylinder may be extended from the state shown in FIG. Then, the engagement rod 5 and the engagement pulley 6 are pushed up, and the lower pallet 3 together with the second pulley 9 is lowered to the lower position L by its own weight and reaches the bottom V of the parking space S. During this time, the chain 10 is tensioned by the weight of the lower pallet 3 and no slack portion is generated.
[0034]
Further, as shown in FIGS. 1 and 3, balance chains 14 are disposed on both sides of each of the upper pallet 2 and the lower pallet 3. The balance chain 14 is for raising and lowering the pallets 2 and 3 while keeping the pallets 2 and 3 substantially horizontal even when a lifting force is applied to the rear part of the pallets 2 and 3 when the pallets 2 and 3 are raised and lowered. A pair of front and rear balance pulleys 15 and 16 are disposed at the front end and the rear end on both sides of each pallet 2 and 3, respectively. On both sides of the upper pallet 2, each of the balance chains 14 is fixed at one end to the upper position U of the parking space S, then engaged with the front balance pulley 15 from below, and then with the rear pulley 16 from above. The other end is fixed to the middle position M after engaging. Also on both sides of the lower pallet 3, one end of the balance chain 14 is fixed at the middle position M of the parking space S, then engaged with the front balance pulley 15 from below, and then engaged with the rear pulley 16 from above. In addition, the other end is fixed to the lower stage position L.
[0035]
Since the rear balance pulley 16 is also lifted when any of the pallets 2 and 3 are raised, the front balance pulley 15 is lifted by the tension of the balance chain 14, and as a result, the horizontal state of the pallets 2 and 3 is maintained. To rise. When the pallets 2 and 3 are lowered, the pallets 2 and 3 are similarly lowered while maintaining the horizontal state.
[0036]
In FIG. 3, the rear balance pulley 16 is shifted forward from the actual position for easy understanding.
[0037]
FIG. 4 shows another lifting device 21. This elevating device 21 is configured such that a double speed mechanism 22 is disposed on each engagement pulley 6 in the elevating device 1 shown in FIGS. 1 and 3. 1, the rod 7a of the hydraulic cylinder fixed to the engaging rod 5 is fixed to the connecting rod 23 that supports the left and right double speed mechanisms 22 at both ends, as shown in FIG. It is also different. Since the other configurations are the same, the same members are denoted by the same reference numerals and the description thereof is omitted.
[0038]
As shown in FIGS. 4 and 5, the double speed mechanism 22 is capable of moving the pallets 2 and 3 by a distance approximately twice the stroke of the hydraulic cylinder 7 when the hydraulic cylinder 7 is expanded and contracted. The structure is hung around the support rod 24, the third pulley 25 and the fourth pulley 26 rotatably attached to the upper and lower ends of the support rod 24 arranged in the vertical direction, and both pulleys 25, 26. A loop-like chain (hereinafter referred to as a loop chain) 27. As illustrated, a part of the loop chain 27 is fixed to the parking space S (which may be a wall surface or a beam), and the other part is fixed to the engagement pulley 6.
[0039]
Therefore, as shown in FIG. 5, for example, when the rod 7 a of the hydraulic cylinder 7 is contracted downward from the state shown in FIG. 4, the support rod 24 moves downward along with the pulleys 25 and 26 and the engagement pulley 6 below the rod 7 a. It is pulled down by the stroke of (indicated by a two-dot chain line). At the same time, since a part of the loop chain 27 is fixed in the parking space S, the loop pulley 27 rotates in the counterclockwise direction in the figure, so that the engagement pulley 6 has its rotation distance (the same distance as the stroke of the rod 7a). Is further lowered downward (indicated by a two-dot chain line). That is, it is pulled downward by a distance that is approximately twice the stroke of the hydraulic cylinder 7. By doing so, the upper pallet 2 is pulled down from the upper position U shown in FIG. 6A to the middle position M shown in FIG. 6B when the upper locking device 13 is retracted to the non-operating position. On the other hand, if the double speed mechanism 22 is pulled down with the upper locking device 13 applied to the operating position, the lower pallet 3 is pulled up to the middle position M as shown in FIG.
[0040]
When the rod 7a is extended upward, the support rod 24 is pushed upward together with the pulleys 25 and 26 and the engaging pulley 6 by the upward stroke of the rod 7a. At the same time, the loop chain 27 is Since it rotates in the direction, the engagement pulley 6 is further pulled upward by the rotation distance. That is, it is pushed upward by a distance that is approximately twice the stroke of the hydraulic cylinder 7. By doing so, the upper pallet 2 in the middle position M is pushed up to the upper position U. On the other hand, the lower pallet 3 at the middle position M is lowered to the lower position L.
[0041]
In the lifting device 21 in which the double speed mechanism 22 is disposed, a part of the weight of the upper pallet 2 is supported when the upper pallet 2 is moved up and down from the fixing point K to the parking space S of the loop chain 27. That is the part up to the pulley 6.
[0042]
According to the lifting device 21, when the upper pallet 2 and the lower pallet 3 are moved up and down, the stroke of the rod 7a of the hydraulic cylinder 7 is almost half that of the lifting device 1 of FIG. This means that the lifting speed of the pallets 2 and 3 can be increased up to twice that of the lifting apparatus 1 of FIG. 1 when necessary. The other operations, that is, the operations of the pallets 2 and 3, the pulleys 4, 6, 8, 9, 15, 16, and the chain 10 are not different from those of the lifting device 1 of FIG.
[0043]
Of course, the lifting device 21 is also provided with a balance chain (not shown) similar to that shown in FIG. In order to guide the vertical movement of the double speed mechanism 22 and the connecting rod 23, a guide member similar to that described above may be provided.
[0044]
A pulley can be added to the lifting devices 1 and 21 as necessary. For example, with respect to the lifting device 1 of FIG. 1, as shown in FIG. 7, the chain 10 is suspended between the fixed pulley 4 and the engaging pulley 6 so that the chain 10 is engaged from above. Two upper fixed pulleys 28 may be provided. As described above, according to the present invention, the lifting function of the lifting devices 1 and 21 shown in FIGS. 1 and 2 and the lifting device 31 described later can be changed as necessary, such as changing the position of the chain. It is possible to add a fixed pulley at a position that does not affect the position. By adding a fixed pulley, the interference between the fixed pulley 4 and the engaging pulley 6 can be easily avoided, and the degree of design freedom of the size and layout of the fixed pulley 4 and the first pulley 8 is increased. be able to.
[0045]
The lifting device 31 shown in FIG. 8 does not drive the engaging pulley up and down by the hydraulic cylinder 7, but directly pulls the chain 10 up and down.
[0046]
That is, also in the lifting device 31, the fixed pulley 4 is disposed above the parking space S, the first pulley 8 is disposed on the upper pallet 2, and the second pulley 9 is disposed on the lower pallet 3. On the other hand, the engaging pulley 32 is configured to engage with the portion of the upper pallet 2 in front of the fixed pulley 4 as shown, unlike the lifting device 1 of FIG. This is because the rod 7 a of the hydraulic cylinder 7 is fixed to a portion of the chain 10 between the fixed pulley 4 and the second pulley 9. Therefore, it is not necessary to attach the engagement rod 5 to the fixed pulley 4 in particular. When the engagement rod 5 is not attached, an engagement portion (not shown) that allows the engagement pulley 32 to engage from below is formed on the upper pallet 2. One end of the chain 10 is fixed to the parking space S, and is engaged with the engaging pulley 32 from below and suspended. Then, the chain 10 is engaged with the fixed pulley 4 from above, and then is lowered to the second pulley 9. The other end is fixed in the vicinity of the middle position M of the parking space S after engaging with the first pulley and then engaging with the first pulley from above.
[0047]
On the other hand, the connection between the chain 10 and the rod 7a of the hydraulic cylinder at the left and right in the vicinity of the rear end of the upper pallet 2 is fixed so as to pass the connecting rod 33 to the corresponding portion between the chains 10, and the central portion of the connecting rod 33 This is done by fixing the tip of the rod 7a of the hydraulic cylinder. By doing so, the left and right chains 10 can be directly pulled up and down in synchronization. This portion of the connecting rod 33 in the chain 10 is called a driven portion 34.
[0048]
To lower the upper pallet 2 from the traverse reference position shown in FIG. 8A to the middle position M (FIG. 8B), the upper pallet 2 is released via the chain 10 by the hydraulic cylinder 7 by releasing the upper locking device. The chain 10 may be pulled up while supporting its own weight. During this time, the lower pallet 3 remains stationary at its lower end due to its own weight, and no slack is generated in the chain 10.
[0049]
On the other hand, in order to raise the lower pallet 3 from the traverse reference position shown in FIG. 8A to the middle position M (FIG. 8C), the hydraulic cylinder 7 is operated with the stopper 13 of the upper locking device 13 applied. What is necessary is just to pull up the chain 5. By doing so, since the 2nd pulley 9 is pulled up, the lower pallet 3 goes up. Further, the engagement pulley 32 is disengaged from the upper pallet 2 due to its own weight, and the sag of the chain 10 is suspended.
[0050]
Since the elevating device 31 directly pulls and drives the chain by the hydraulic cylinder 7, the stroke of the hydraulic cylinder 7 is almost twice that of the elevating device 1 shown in FIG.
[0051]
In addition, you may arrange | position the lower stage locking apparatus which makes the raising of the lower stage pallet 3 located there in the lower stage position L of the raising / lowering apparatus 1,21,31 mentioned above impossible. In that case, for example, the lower locking device may be one in which the vertical relationship between the upper locking device 13 and the upper pallet 2 shown in FIG. And what is necessary is just to comprise so that the stopper arm may be rock | fluctuated and driven between the action position which engages with the upper surface of the lower pallet 3 from upper direction, and the non-action position from which engagement is cancelled | released.
[0052]
Each of the pulleys described above may be a sprocket wheel having engagement teeth with a chain, or may be a pulley shape having no engagement teeth.
[0053]
All of the hydraulic cylinders described above are installed on the floor of the parking space. Alternatively, the hydraulic cylinders may be suspended on the ceiling side so that the rods are positioned below.
[0054]
【The invention's effect】
According to the present invention, the upper-stage accommodation means and the lower-stage accommodation means can be lifted and lowered separately with almost no sag of the transmission means, and as a result, there is no time lag at the start of movement of each accommodation means. In addition, since the upper and lower housing means can be moved up and down separately by at least one straight drive means, it is possible to reduce costs and to suppress vibration and noise that are likely to be generated by the rotation drive means.
[0055]
Further, the stopper is not operated in a state where a load is applied, and the driving condition does not change between rising and lowering of the housing means.
