Description

  The present invention relates to a mechanical multistage parking apparatus that moves up and down and traverses a plurality of pallets for storing a plurality of vehicles to carry in and out of the vehicles.

  4 and 5 are mechanical multi-stages of a type in which a plurality of pallets are stacked in a row or a plurality of rows, arbitrarily selected pallets are moved up and down, traversed to a predetermined loading / unloading position, and loading / unloading is performed. A parking device 1 is schematically shown. This mechanical multistage parking apparatus 1 has a configuration in which a plurality of pallets 2, 3, 4, and 5 are arranged in a row in the vertical direction and provided in a plurality of rows. In the illustrated example, a skeleton frame 12 is assembled on the ground portion, and three pallets 2, 3, 4 are provided in the skeleton frame 12. In addition, an underground pit 13 is formed in the underground part, and only one pallet 5 is provided in the underground pit 13. In this description, the respective pallets are referred to as the uppermost pallet 2, the ground middle pallet 3, the ground surface pallet 4, and the underground pallet 5.

  The uppermost pallet 2 is provided for each row as shown in the figure. Moreover, each pallet 2a-2c is provided with the raising / lowering mechanism using a four-point hanging raising / lowering chain, and raises / lowers each independently between the uppermost stage and the ground surface GL. FIG. 4 shows a state where the pallets 2a and 2b are positioned at the uppermost stage and the pallet 2c is lowered to the ground surface.

  The second above-ground middle pallet 3 from the top is one row fewer than the uppermost pallet 2 and includes two pallets 3a and 3b in the illustrated example. In addition, each pallet 3a, 3b is moved to the frame 7 (FIG. 5) that moves left and right on the rail 6 by a traveling wheel (transverse), and a lifting mechanism similar to the lifting device of the uppermost pallet 2 (for convenience of illustration, 5 shows only one four-point lifting / lowering chain 14). Therefore, each of the ground middle pallets 3a and 3b can move up and down between the second stage and the ground surface GL and can traverse.

The third surface pallet 4 from the top is one row fewer than the uppermost pallet 2 and includes two pallets 4a and 4b, like the middle ground pallet 3. Each pallet 4a, 4b can traverse the ground surface GL. The traverse mechanism of the ground surface pallet 4 travels on traveling rails (see 21 and 22 in FIG. 1) on rails (see 24 and 25 in FIG. 1) laid in front and rear positions of the opening of the underground pit 13. It has a structure.
Furthermore, the underground pallet 5 is provided for each row in the same manner as the uppermost pallet 2. An elevating device using the elevating chain 15 and the balance chain 16 (the elevating chain 15 is a two-point suspension, and has a structure in which the balance in the front-rear direction is maintained by the balance chain 16. Also, FIG. The portion indicated by 19 is a sprocket for hoisting the elevating chain 15 and is driven by a motor (not shown). As a result, each pallet 5a, 5b, 5c independently rises from the pit 13 to the ground surface GL. It is possible.

  And the mechanical multistage parking apparatus 1 calls in and out of the vehicle by calling a pallet arbitrarily selected from the pallets 2, 3, 4 and 5 to the ground surface GL. Further, when calling the underground pallet 5 to the ground surface GL, the pallet 2 is raised to the uppermost stage so as not to hinder the rise of the corresponding underground pallet, and the second pallet 3 and the third pallet 4 can be retracted in the horizontal direction. Further, when calling the pallets 2 and 3 to the ground surface GL, other pallets can be retracted to a position that does not hinder the lowering of the corresponding pallet.

  In addition, the front of the pallet (4a, 4b, 2c) located on the ground surface GL is closed with the gate 10, and the interior of the mechanical multistage parking device 1 is easily separated from the outside, thereby improving safety. I am letting. When the vehicles 8 and 9 are loaded and unloaded, the gate 10 can be stored underground or can be raised to a position where it does not interfere with the vehicles 8 and 9. In addition, the part shown with the code | symbol 11 in FIG. 4 is the fence fixed to the beam of the parking apparatus.

  By the way, the mechanical multistage parking apparatus 1 installed outdoors needs to arrange | position each pallet 2-5 inclining a little in the front-back direction considering the drainage property of rainwater. And about the surface stage pallet 4 and the underground stage pallet 5, it is common to set it as the front inclination which made the front lower than back. On the other hand, for the uppermost pallet 2 and the middle ground pallet 3, in order to prevent rainwater dripping from the pallet from falling on the user of the parking apparatus, the front pallet 2 is generally set to a rearward inclination that is higher than the rear. (For example, see Patent Document 1)

JP 2002-167994 A ([0002], FIG. 1)

  Now, due to the lack of parking lots in today's urban areas and the need to secure parking lots in apartment buildings, the number of installations of mechanical multi-level parking devices 1 is increasing. Regardless of the location. However, when the mechanical multistage parking apparatus 1 is installed indoors, the installation space is often more restricted than when installed outdoors, and the mechanical multistage parking apparatus 1 should be miniaturized as much as possible. Is desired. A problem in reducing the size of the apparatus is an increase in the ceiling height (distance between the upper and lower pallets) for each stage accompanying the inclination of each pallet. Moreover, in the case of indoor installation, in principle, there is no problem of drainage of rainwater, so there is no need to incline the pallets, and the inclination of each pallet is completely meaningless.

However, the conventional mechanical multi-level parking apparatus 1 has a structure on the assumption that each component has an inclination on the pallet. For example, when the rear of the underground pallet 5 is lowered to eliminate the forward inclination, the rear sprocket 18 among the front sprocket 17 and the rear sprocket 18 around which the balance chain 16 passing through the lower surface of the underground pallet 5 is hung. This causes a problem in the construction of the lifting mechanism, such as losing the installation space. In this case, in order to prevent the basic structure of the lifting mechanism of the underground pallet 5 from being changed, it is necessary to make the pit 13 deeper and secure the installation space for the rear sprocket 18. This would be against the request to reduce the installation cost of the underground pit 13 by making the underground pit 13 as shallow as possible.
In addition, the mechanical multi-level parking device 1 is arranged in advance at a higher position than the front rail, among the rails constituting the traverse mechanism of the ground level pallet 4 in order to give the ground level pallet 4 a forward inclination. Since the skeleton frame 12 has a structure to do this (see Fig. 1 (b)), the structure of the skeleton frame 12 at the periphery of the ground pallet is changed in order to match the height of the front and rear rails. There is a need to. Then, the difference in the frame specifications between the indoor installation apparatus and the outdoor installation apparatus affects not only the main parts but also a large number of small and medium parts, resulting in a problem that an increase in equipment cost cannot be avoided.

  The present invention has been made in view of the above-mentioned problems, and the object of the present invention is to satisfy the requirements regarding the inclination angle of the pallet, which differs depending on the installation location, without increasing the cost. Another object is to provide a mechanical multistage parking device.

In order to solve the above problems, a mechanical multistage parking apparatus according to claim 1 of the present invention includes an underground pallet that can be raised from the underground pit to the ground surface by an elevating mechanism that combines an elevating chain and a balance chain.

According to the present invention, the raising and lowering chain of the underground pallet and the hanging bracket of the balance chain are selectively equipped from differently shaped brackets that determine the forward inclination angle of the underground pallet, thereby changing the bracket. Only by this, the inclination angle of the underground pallet can be changed. And even when the forward inclination of the underground pallet is eliminated, it is possible to arrange an elevating mechanism on the lower surface of the pallet as in the case where the forward inclination is provided without increasing the depth of the underground pit. It becomes.
Further, the shaft mounting bracket of the traveling wheel of the surface pallet is selectively equipped from among different shapes of metal that determines the forward inclination angle of the surface pallet, so that the surface pallet of the surface pallet can be changed only by changing the bracket. The inclination angle can be changed. In addition, there is no change in the structure of the skeleton frame in the periphery of the surface stage pallet depending on the presence or absence of the forward inclination of the surface stage pallet. Specifically, the structure of the surface pallet and the area around the surface pallet are selected by selecting the optimal shaft mounting bracket from the brackets with different mounting positions of the wheel axles in the vertical direction and fixing them to the surface pallet. It is possible to easily change the inclination angle of the surface pallet without changing the configuration of the skeleton frame in the section.

The mechanical multistage parking apparatus according to claim 2 of the present invention is the mechanical multistage parking apparatus according to claim 1, wherein the lifting chain of the underground pallet and the lifting hardware of the balance chain are attached to the underground pallet. The shape of the part is the same, and the mounting position of the rotating shaft of the sprocket that hangs the chain is selected from the brackets that are vertically different.
According to the present invention, the structure of the underground pallet can be obtained by selecting the optimal suspension bracket from the brackets with different mounting positions of the rotating shafts of the sprockets that hang the chain in the vertical direction and fixing them to the underground pallet. It is possible to easily change the inclination angle of the underground pallet without changing the configuration of the lifting mechanism.

The uppermost pallet is provided with an elevating mechanism using a four-point hanging elevating chain attached to the skeleton frame, and the length of the four-point hanging elevating chain is determined when the uppermost pallet is raised and lowered. The pallet is adjusted to take a horizontal posture.
According to the present invention, the pallet takes a horizontal posture during the ascending position and ascending / descending of the uppermost pallet, so that the structure of the uppermost pallet and the structure of the elevating mechanism can be changed without changing the structure of the uppermost pallet. The required ceiling height can be reduced.

  Since this invention was comprised in this way, it becomes possible to provide the mechanical multistage parking apparatus from which the inclination angle of a pallet differs according to an installation place, without raising the cost accompanying the big change of a structure.

The hanger 20A is with respect to the axis of rotation of the front sprocket 17, which is pivotally attached to the lifting lugs 26, the position of the rotation axis of the rear sprocket 18 has a higher becomes such a shape by a height H _5. 2 is a connecting part of the lifting chain 15 (FIG. 1).
On the other hand, the hanging bracket 20B installed in the outdoor-type mechanical multistage parking apparatus 1B shown in FIG. 1 (b) is similar in shape to the hanging bracket 20A, but the overall height of the bracket is higher than that of the hanging bracket 20A. The distance E from the mounting portion 27 to the mounting position of the rear sprocket 18 with respect to the underground pallet 5 is larger than that of the hanging bracket 20A, and the height H ₅ = 0.

State, that is, the mounting height of the rear sprocket 18 is different from the hanging bracket 20B towards the hanger 20A, by a height H ₅ becomes higher, an amount corresponding to such a height H _5, that wound around the balance chain 16 by lowering the rear end portion of the ground lower pallet 5 in, it can be the ground lower pallet 5 and the horizontal (Meanwhile, outdoor specifications of the mechanical multistage parking apparatus 1B, the height H ₅ only land lower pallet 5 The rear end portion is lifted with respect to the front end portion.)
In addition, the shape of the attachment part 27 with respect to the underground pallet 5 is common in both the hanging metal fittings 20A and 20B. In addition, the difference in the shape of the ground stage pallet 4 and its surrounding components between the indoor multi-level parking device 1A and the outdoor multi-level parking device 1B is mainly that of the hanging brackets 20A and 20B. It has become.

FIG. 3 is an enlarged view of the peripheral portion of the front traveling wheel 21 and the rear traveling wheel 22 of the ground surface pallet 4 of the indoor multi-level parking apparatus 1A. As shown in FIG. 3 (b), the front traveling wheel 21 is actually fixed to the ground surface pallet 4 via the shaft fitting 29 similarly to the rear traveling wheel 22. The shaft mounting bracket 23A has a shape such that the position of the rotation shaft of the rear traveling wheel 22 is increased by a height H ₄ with respect to the rotation shaft of the front traveling wheel 21 mounted on the shaft mounting bracket 29. is doing. Also in the embodiment of the present invention, as shown in FIG. 1, the rear rail 25 is disposed at a higher position than the front rail 24, but the height H ₄ is equal to the distance between the front rail and the rear rail 25. The height is equivalent to the height difference.
On the other hand, the shaft mounting bracket 23B installed in the outdoor-type mechanical multistage parking apparatus 1B shown in FIG. 1B is similar to the shaft mounting bracket 23A in overall shape, but compared to the shaft mounting bracket 23B. The mounting position of the axle of the rear traveling wheel 22 with respect to the pallet 4 is low, and the height H ₄ is set to be zero.

That is, the mounting height of the rear running wheels 22 against the ground stage pallet 4, towards the shaft attachment bracket 23A is compared with the axial attachment brackets 23B, increased by a height H _4, the amount of such a height H _4, Absorbing the difference in height between the front rail 24 and the rear rail 25, the rear end of the ground level pallet 4 is lowered, and the attitude of the ground level pallet 4 in a state where it is installed on the front rail 24 and the rear rail 25 is leveled. be able to.
In addition, the shape of the attachment part 30 with respect to the surface stage pallet 4 is common in both the shaft mounting brackets 23A and 23B. In addition, the difference in the shape of the ground stage pallet 4 and its peripheral components between the indoor-specific mechanical multistage parking apparatus 1A and the outdoor-specific mechanical multistage parking apparatus 1B is mainly due to the shaft mounting brackets 23A, 23B. It has become only.

Furthermore, in the indoor-specific mechanical multi-stage parking apparatus 1A shown in FIG. 1A, the length of the four-point hanging lift chain 14 (see FIG. 5) of the ground middle stage pallet 3 is the height of the ground middle stage pallet 3 ascending and descending. The middle pallet 3 on the ground is adjusted to take a horizontal posture.
On the other hand, in the outdoor-type mechanical multistage parking apparatus 1B shown in FIG. 1 (b), the length of the four-point suspension lifting chain 14 of the ground middle pallet 3 is inclined backward so that the front of the ground middle pallet 3 is higher than the rear. It has been adjusted to be.
Then, as shown in FIG. 1 (a), the ceiling height _HA required for the ground pallet of the indoor multi-level parking device 1A is set as shown in FIG. mechanical multistage parking device 1B outdoor specifications shown in b), compared with the ceiling height H _B required for terrestrial pallet, it becomes possible to reduce.

Note that the length of the four-point lifting / lowering chain of the uppermost pallet 2 (see FIGS. 4 and 5) not shown in FIG. The pallet 2 is adjusted to take a horizontal posture, and the effect obtained by such a configuration is the same as that in the case of the ground middle pallet 3.
Furthermore, there is no difference in the shape of the above-ground middle pallet 3 and the uppermost pallet 2 and their peripheral components between the indoor-specific mechanical multi-level parking device 1A and the outdoor-specific mechanical multi-level parking device 1B. The only difference is that the length of the four-point chain is adjusted.

According to the embodiment of the present invention having the above-described configuration, the following operational effects can be obtained. First, the lifting bracket 15 and the balance chain 16 for the underground pallet 5 are selectively equipped from the differently shaped brackets 20A and 20B that determine the forward inclination angle of the underground pallet 5, and the bracket 20A, The inclination angle of the underground pallet 5 can be changed only by changing 20B. Accordingly, as shown in FIG. 1 (a), even if the forward inclination of the underground pallet 5 is eliminated, the depth D of the underground pit 13 is not increased, as shown in FIG. 1 (b). Similarly to the case where the front slope is provided, the rear sprocket 18 constituting the lifting mechanism can be disposed on the lower surface of the underground pallet 5.
Further, the shaft mounting bracket of the rear traveling wheel 22 with respect to the ground level pallet 4 is selectively equipped from the different types of shaft mounting brackets 23A and 23B that determine the front inclination angle of the ground level pallet 4 so that the shaft The inclination angle of the surface stage pallet 4 can be changed only by changing the fittings 23A and 23B. And it can prevent that a structure arises in the structure of the frame | skeleton 12 in the ground stage pallet periphery part by the presence or absence of the front inclination of the ground level pallet 4. FIG.

  Moreover, in the embodiment of the present invention, the lifting chain 15 and the balance chain 16 hanging bracket for the underground pallet 5 have the same shape of the mounting portion 27 for the underground pallet 5, and the rear sprocket 18 that hangs around the chain. The mounting position of the rotary shaft is selected from the hanging brackets 20A and 20B that are different in the vertical direction, and the hanging brackets 20A and 20B can be mounted without changing the structure of the underground pallet 5 and the structure of the lifting mechanism. It is possible to easily change the inclination angle of the underground pallet 5 only by selecting the optimal hanging bracket from the inside and fixing it to the underground pallet 5.

  Further, the shaft mounting bracket of the rear traveling wheel 22 with respect to the ground level pallet 4 has the same shape of the mounting portion 30 with respect to the ground level pallet 4, and the shaft mounting bracket 23A in which the mounting position of the axle of the rear traveling wheel 22 is different in the vertical direction. 23B is selected and equipped, and without changing the structure of the surface pallet 4 or the structure of the skeleton frame 12 in the periphery of the surface pallet 4, it can be optimally selected from the shaft mounting brackets 23A and 23B. The inclination angle of the surface stage pallet 4 can be easily changed only by selecting the shaft mounting bracket and fixing it to the surface stage pallet 4.

Furthermore, by adjusting the length of the four-point suspended lifting chain that constitutes the lifting mechanism of the ground middle pallet 3 so that the pallet 3 takes a horizontal posture during the rising position and lifting of the middle ground pallet 3, It is possible to reduce the ceiling height required for the ground pallet of the mechanical multistage parking apparatus without changing the structure of the middle ground pallet 3 or the structure of the lifting / lowering mechanism.
Further, by adjusting the length of the four-point hanging lift chain that constitutes the lifting mechanism of the uppermost pallet 2 so that the pallet 2 takes a horizontal posture even when the uppermost pallet 2 is raised and lifted. The ceiling height required for the ground pallet of the mechanical multistage parking apparatus can be reduced without changing the structure of the uppermost pallet or the structure of the lifting mechanism.

Although not shown in the drawings, both the indoor and outdoor mechanical multistage parking devices 1A and 1B have a lower rail or a structural part fixed to the lower surface when the ground middle pallet 3 descends to the ground surface. By placing it on the rear rail 25, the above-ground middle pallet 3 is positioned in the vertical direction, and a structure in which the rear end of the above ground middle pallet 3 is intentionally inclined forward with respect to the front end is adopted. ing.
While the ground middle pallet 3 is inclined forward, the rear two-point suspension chain of the four-point suspension lifting chain 14 is naturally loosened, so that it is possible to absorb the change in the height difference before and after the middle pallet 3 on the ground.

The reason for adopting such a structure is as follows, and is particularly important in the indoor-type mechanical multistage parking apparatus 1A. That is, in the indoor-specific mechanical multistage parking apparatus 1A, when the ground middle pallet 3 is lowered to the ground surface and the horizontal posture of the ground middle pallet 3 is to be maintained, In order to avoid interference, it is necessary to change the basic configuration of the skeleton frame 12 and lower the rear rail 25 to the same height as the front rail 24. In addition, in order to avoid interference between the rear rail 25 and the hanging bracket 20A of the underground pallet 5 when the underground pallet 5 is raised, an outdoor specification hanging bracket 20B having a higher overall height of the bracket is used. It is necessary to use it. As a result, it is necessary to make the depth D of the underground pit 13 deeper, which hinders the promotion of downsizing, which is an advantage of the indoor-spec mechanical multistage parking apparatus 1A.
For the above reasons, the mechanical multistage parking apparatus 1A, 1B according to the embodiment of the present invention adopts a structure in which the ground middle stage pallet 3 is inclined forward when the ground middle stage pallet 3 descends to the ground surface. Yes. In addition, the trouble by making the ground middle stage pallet 3 incline forward does not arise in particular, and it becomes more advantageous in terms of smoothness of entering and leaving the vehicle. The above structure is also employed in the uppermost pallet 2 and has the same effects as the case of the above-ground middle pallet 3.

As described above, according to the embodiment of the present invention, by selecting the suspension fittings 20A and 20B and the shaft attachment fittings 23A and 23B, the indoor-specification mechanical multistage parking apparatus 1A that promotes miniaturization as much as possible, It is also possible to provide a mechanical multi-level parking apparatus 1B of outdoor specification that takes into account the drainage of rainwater.
In addition, by further increasing the types of hanging brackets 20A and 20B and shaft mounting brackets 23A and 23B, and selecting and installing them from them, the inclination angle of each pallet can be further increased or decreased as required. It can be easily performed.
