Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention automatically folds a portion of a hoisting chain, which is hoisted when an upper pallet is lifted, horizontally and in multiple layers with a certain length, so that the chain hangs long or the chains are entangled with each other. The present invention relates to a multi-stage parking device that effectively prevents the above.

[0002]

2. Description of the Related Art In the case of a conventional multistage parking system,
As means for raising and lowering the upper pallet, for example, FIG.
Hold the drive motor 101 as shown in (a) and (b).
02 is fixed to the rear frame 102b, and a drive shaft 103 along the rear frame 102b is provided above the rear frame 102b. The drive shaft 103 is attached to the sprocket 104 of the motor 101 and the looped chain 10 is provided.
The sprocket 106 that is interlocked via the 5 is fixed, and the wire drums 109 are provided at both ends of the drive shaft 103.The drive shaft 103 is rotated, and the wires 108 whose one ends are connected to the pallet 107 are connected to the wire drum 109. It is known to wind up.

However, in this conventional apparatus, the wire drum 109 having a relatively large volume and the drive motor 101 are arranged in the rear frame 102b of the holding frame 102, and the length (depth) of the space of the vehicle storage portion is small. Since the length of the pallet is determined in consideration of the dimensions of the wire drum 109 and the like, there is a problem that a sufficient installation space is required to install such a conventional device.

As a means for reducing the length (depth) and size of the vehicle storage space, a hoisting chain and a hoisting sprocket are used instead of the wire 108 and the wire drum 109 which constitute the above-mentioned conventional apparatus. There is a method of raising and lowering the upper pallet by hoisting and lifting the hoisting chain with a hoisting sprocket.In this method, the hoisting chain hoisted with the hoisting sprocket either hangs down long or hoists. It is general that the lifted chain is stored in a chain bag provided below it.

However, if the hoisted hoisting chain hangs down for a long time, the chain may be caught by a peripheral device member, which may cause a device failure. In the case of a structure in which the chains are stored in a bag, the stored chains may become entangled in the chain bag and the chains may not be able to be put in and taken out smoothly. When the hoisting chain is forcibly pulled out from the chain bag, an unexpected action force such as a twisting force is applied to the chain, and in the worst case, the load may lead to breaking of the chain.

In particular, such a phenomenon is more likely to occur as the lifting distance of the upper pallet increases, in other words, as the length of the lifting chain increases.

[0007]

The lower pallet 8 is arranged in the lower vehicle storage portion 2 leaving a space for one pallet. In addition, in FIG.
Although the case where one lower pallet 8 is arranged in the lower vehicle storage portion 2 for two pallets is shown, in the present invention,
A maximum of N-1 in the lower vehicle storage unit 2 for N pallets
A lower pallet 8 of sheets can be arranged.

As means for moving the lower pallet 8 in the lateral direction, for example, the lower pallet 8 is moved to the front end portion 9 and the rear end portion.
As shown in FIG. 2, two or more (two in FIG. 1) drive rollers 11 provided on each of 10 are provided on the first rail 12 provided on the front and rear reference surfaces 6 of the lower pallet 8. , And at least one of the drive rollers 11 is interlocked with a geared motor 13 with a brake fixed to the rear corner of the lower pallet 8 so that the drive roller 11 rolls on the first rail 12. It is preferable to configure as follows.

The upper vehicle accommodating sections 3 to 5 include a lower pallet 8
And / or the holding frame 14a located above the void.
.About.14c and upper pallets 15a to 15c. The upper pallets 15a to 15c are supported by the holding frames 14a to 14c and can be moved up and down between the holding frame position and the reference plane 6 position.

Although FIG. 1 shows a case in which three stages of upper vehicle storage units 3 to 5 are arranged above the lower vehicle storage unit 2, in the present invention, at least one stage of upper vehicle storage unit is provided. The target is a two or more-stage parking device with a storage unit.

However, in the case of a parking device with three or more stages,
Upper pallet 15c located in the uppermost vehicle storage section 5
In order to make it possible to move up and down between this position and the position of the reference plane 6, the holding frames 14a, 14b and the upper pallets 15a, 15b located in the other upper vehicle storage parts 3, 4 are
It is necessary to move the upper pallet 15c laterally to a position that does not interfere with the lifting and lowering of the upper pallet 15c.

Holding frames 14a, 14b and upper pallet 15
As a means for moving a, 15b in the lateral direction, it is preferable to make the holding frames 14a, 14b movable. For example, in the case of the four-stage parking apparatus shown in FIG. 1, the second and third stages are used. Retaining frames located in the upper vehicle storage parts 3 and 4 of the eye
Two or more (two in FIG. 1) drive rollers 16a and 16b provided on the front frame and the rear frame of 14a and 14b, respectively, are fixed to the ground planes on the front sides and the rear sides of the holding frames 14a and 14b. Are arranged on the second and third rails 18a and 18b provided laterally between the columns 17 (four in FIG. 1), and at least one of the drive rollers 16a and 16b is attached to each of the holding frames 14a and 14b. It is preferable to move the holding frames 14a, 14b and the upper pallets 15a, 15b in the lateral direction by interlocking with the geared motors with brakes 19a and 19b fixed to the front portion of the one side frame.

Since the upper pallet 15c located in the uppermost upper vehicle storage portion 5 is at least capable of moving up and down, the holding frame 14c is formed as a fixed frame in FIG. Also, the holding frames 14a and 14b located in the upper side vehicle storages 3 and 4 of the third stage may be movable.

As means for raising and lowering the upper pallets 15a to 15c, geared motors with brakes 20a to 20c, which are first driving means fixed to the rear portions of the side frames of the holding frames 14a to 14c, are fixed. Then, the first drive shafts 21a to 21c interlocked with these are held on the holding frame 14a.
Installed along the upper side of the rear frame of ~ 14C along these lines, the first drive shaft
Two hoisting sprockets 22a to 22c and 23a to 23c each having the same radius of gyration at both ends of 21a to 21c.
The first and second lifting chains 24a to 24c and 25a to 25c, one end of which is fixedly connected to the front and rear sides of both sides of the upper pallets 15a to 15c, respectively. To 14c through the first direction changing means 26a to 26c such as idlers arranged on the side frames, and the corresponding winding sprockets 22a to 22c and 23, respectively.
This is done by rotating the first drive shafts 21a to 21c in two forward and reverse directions by rotating the first drive shafts 21a to 21c in such a manner that the other ends 28 of the hoisting chains are fixedly connected to the holding frames 14a to 14c, respectively.

The main feature of the present invention is, as shown in FIG. 5, a chain hanger which is fixedly connected to a portion of the hoisting chains 24 and 25 which are hoisted by hoisting sprockets 22 and 23 at a predetermined interval L. 29 (see FIG. 3) is provided around the engaging portions of the hoisting chains 24 and 25 and the hoisting sprockets 22 and 23, and guides the movement of the chain hanger 29 associated with hoisting of the hoisting chains 24 and 25. An end portion which is located below the tip portion 30 and the winding sprockets 22 and 23 and which aligns the chain hangers 29 guided by the tip portion 30 in a line.
The chain hanger support fitting 32 having 31 is fixed to the holding frame 14.

FIG. 3 is a side view of a state in which the upper pallet 15c located in the uppermost upper vehicle storage section 5 is lowered to reach the position of the reference plane 6, and in this state, And the position of the chain hanger 29 provided on the second lifting chains 24, 25.
FIG. 4 shows a state of the chain hanger 29 fixedly connected to the lifting chains 24, 25.

The arrangement interval L of the chain hangers 29 depends on the length dimension of the terminal side portion 31 of the chain hanger support fitting 32,
It is determined in consideration of the length dimension 1 and the like when the lifting chains 24, 25 are folded on the chain hanger support fitting 32. The length 1 when the hoisting chain is folded is 1/2 the length L of the chain hanger 29.

The chain hanger support fitting 32 has a tip end portion 30 formed in a convex curvature so as to extend around the engaging portion between the hoisting chains 24, 25 and the hoisting sprockets 22, 23, and its end portion. In the side portion 31, since the lifting chains 24 and 25 folded in the lower position thereof are aligned in a horizontal row, the lifting chain positioned in the idle space below the winding sprockets 22 and 23 is located. In this case, the distal end portion 31 is formed with a convex curvature opposite to the distal end portion 30, and the chain hanger support fitting 32 has an S-shape (in FIG. 5). The S-shape is facing down.)
Is more preferable.

[0025] Tip of the chain hanger support 32
Reference numeral 30 denotes a portion where the chain hanger 29 first fits into the support fitting 32, and in order to facilitate this fitting, the tip end portion 30a thereof may have a pointed shape such as a conical shape. More preferably, as shown in FIG. 7, the upper part of the conical shape is further cut into a flat shape.

Further, the chain hanger support fitting 32 needs to be arranged at an appropriate position in relation to the winding side sprockets 22 and 23 at the tip end side portion 30 thereof. That is, if the mounting position of the chain hanger support fitting 32 is not proper, the lifting chains 24 and 25 are extremely pressed by the support fitting 32 toward the hoisting sprockets 22 and 23, or conversely, the lifting chains are Since the chain hanger fitted to the support fitting 32 is forcibly pulled toward the support fitting 32, as a result, the hoisting sprockets 22 and 23 can smoothly hoist the lifting chains 24 and 25. Because it will not be possible.

Therefore, the chain hanger support fitting 32 is
The lifting chains 24, 25 are arranged at positions where the engaging portions are appropriately pressed, and the lifting chains are
It is preferable to maintain a positive engagement state between 24 and 25 and hoisting sprockets 22 and 23.

As described above, in the present invention, by adopting the above configuration, the upper pallets 15a to 15c are
Lifting chain 24,2 that is hoisted when raising
It is possible to effectively prevent the wound chains 24 and 25 from hanging down for a long time and the chains 24 and 25 from being entangled with each other by automatically folding the portion 5 in a horizontal line and in multiple layers with a fixed length.

Further, when the hoisting chains 24 and 25 are hoisted by the hoisting sprockets 22 and 23, these engagement states are normally released when the lower positions of the hoisting sprockets 22 and 23 are reached. Under various usage conditions, the engagement may not be released even when the lower position of the hoisting sprockets 22 and 23 is reached, because the lifting chains 24 and 25 are wound around the hoisting sprockets 22 and 23. It is not preferable to do so.

Therefore, in such a case, as shown in FIGS. 1 and 7, at the lower position of the hoisting sprockets 22 and 23, the engagement state of the hoisting chains 24 and 25 and the hoisting sprockets 22 and 23 is shown. It is preferable to dispose a chain separator 33 that forcibly releases the.

The above description is merely an example of the embodiment of the present invention, and various modifications can be made within the scope of the claims.

For example, the lower pallet 8 and the upper pallet
As shown in FIG. 6, if the tip member 35 is bolted to the front end side of these pallets 8 and 15 with an elastic body 34 such as rubber interposed therebetween, the reference surface 6 is not flat, as shown in FIG. Even when the front ends of the pallets 8 and 15 are lifted up, the tip member 35 elastically deforms when the vehicle is taken in and out, and the tip member 35 can be reliably grounded to the reference surface 6. Can be easy.

Although FIG. 1 shows the case of the two-row, four-stage type on the ground, the number of stages and the number of columns can be appropriately changed as required. In addition, the above-described configuration is applied to the pit type parking device. It is also possible to apply to the above, and in this case, the raising and lowering of the underground pallet may be performed by the same structure as the conventional device.

[0034]

According to the present invention, the hoisted chains 24 and 25 are automatically folded by laterally and repeatedly folding a portion of the hoisting chain that is hoisted when the upper pallet is lifted up to a certain length. It is possible to effectively prevent the chains 24 and 25 from hanging down for a long time and entangled with each other.

Further, in the parking apparatus of the present invention, unlike the conventional apparatus, it is not necessary to dispose a wire drum having a relatively large volume at the rear position of the upper pallet, so that the length (depth) of the vehicle storage space is increased. It is possible to reduce the size,
As a result, it can be installed in a relatively narrow space.
