Description

The present invention relates to a method for modifying a vertical circulation parking device, and more particularly to a modification method suitable for a vertical circulation parking device provided with a take-up weight.

A three-dimensional parking device is known as a facility for parking as many vehicles as possible in a limited site. This three-dimensional parking device includes a horizontal circulation type parking device in which a pallet on which a vehicle is placed is moved back and forth and left and right to accommodate it in an empty space, and a pallet on which a vehicle is placed is raised and lowered and accommodated on the left and right shelves of the hoistway. There are elevator-type parking devices, vertical circulation-type parking devices that circulate and accommodate cages on which vehicles are placed in the vertical direction. Among these parking devices, the vertical circulation type parking device has an advantage that the structure is the simplest and the occurrence of failure is small.

By the way, in recent years, the weight of a vehicle tends to increase with the diversification of functions mounted on the vehicle and the increase in size of the vehicle. In the case of such a vertical circulation type parking device, there is an upper limit to the weight that can be tolerated depending on the strength of the chain because the cage is connected to the chain and circulated and transported. Therefore, the existing equipment may not be able to accommodate heavy vehicles, or the number of vehicles that can be accommodated is limited.

For example, as a countermeasure against the increase in size of a vehicle, a modification method has been proposed in which a part of a cage of existing equipment is replaced with a cage for a large vehicle (see Patent Document 1).

Japanese Unexamined Patent Publication No. 2001-193301

However, in the invention described in Patent Document 1, even if a large vehicle can be accommodated, the weight limit of the accommodated vehicle cannot be changed, and in the end, the increase in vehicle weight is dealt with. I can't.

It is a flow chart which shows the modification method of the vertical circulation type parking device which concerns on one Embodiment of this invention. It is a figure which shows an example of a guide member, (A) shows when there is no guide member, (B) shows when there is a guide member. It is a figure which shows the modification of the guide member.

Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 4. Here, FIG. 1 is an overall schematic view showing a vertical circulation type parking device before modification. FIG. 2 is a flow chart showing a method of modifying a vertical circulation type parking device according to an embodiment of the present invention.

First, the overall configuration of the vertical circulation type parking device 1 before modification will be described with reference to FIG. The vertical circulation type parking device 1 includes a pair of upper sprockets 2 arranged at the upper part of a building (not shown) and a pair of lower sprockets 4 suspended from each of the upper sprockets 2 via a suspended chain 3. A plurality of cages 5 connected to the chain 3 via an attachment 51, and a side chain guide 6 for guiding the movement of the chain 3 in the vertical direction are provided.

The upper sprocket 2 is rotatably supported by a drive frame 7 fixed to the building. Further, the pair of upper sprockets 2 are arranged outside both ends in the longitudinal direction of the cage 5 on which the vehicle is placed. The drive frame 7 includes a pair of side frames 71 that rotatably support the upper sprocket 2 and a girder 72 that connects the side frames 71.

A drive means 73 for rotationally driving the upper sprocket 2 is arranged on the girder 72. The drive means 73 is composed of, for example, a drive motor, a speed reducer, or the like. The upper sprocket 2 and the reduction gear are rotatably supported by the side frame 71, and the upper end of the side chain guide 6 is connected to the side frame 71. The configuration of the drive frame 7 is not limited to the illustrated configuration.

The chain 3 is an endless annular chain that is hung around one upper sprocket 2 and one lower sprocket 4 located below the upper sprocket 2. When the upper sprocket 2 is rotationally driven by the driving means 73, the chain 3 rotates. Further, the chain 3 includes a plurality of chain rollers 31 guided by the side chain guide 6.

The lower sprocket 4 is held in a state of being suspended by a chain 3 hung around the upper sprocket 2. The lower sprocket 4 is a driven sprocket that is rotationally driven by the rotation of the chain 3. The pair of lower sprockets 4 are connected by a driven frame 8 and are rotatably supported.

The driven frame 8 includes a pair of side frames 81 that rotatably support the lower sprocket 4, and a frame structure 82 that connects the side frames 81. Since the chain 3 expands and contracts due to fluctuations in the number of vehicles mounted on the cage 5, the driven frame 8 needs to follow the expansion and contraction of the chain 3. Therefore, unlike the drive frame 7, the driven frame 8 is not fixed to the building.

The frame structure 82 is composed of, for example, flat plates arranged vertically, a connecting frame for connecting the flat plates, a brace as a reinforcing material, and the like. A take-up weight 83 that suppresses the lifting of the lower sprocket 4 is arranged on the frame structure 82. The lower sprocket 4 is rotatably supported by the side frame 81, and the lower end of the side chain guide 6 is connected to the side frame 81. The configuration of the driven frame 8 is not limited to the configuration shown in the figure.

The cage 5 is a basket on which a vehicle is placed. In FIG. 1, for convenience of explanation, only the two cages 5 located above and below are shown, and the drawings of the other cages are omitted. The cage 5 is connected to the chain 3 via a V-shaped attachment 51. Specifically, in the attachment 51, two V-shaped open side ends are connected to the chain 3, and one V-shaped closed end is connected to the cage 5. Further, a chain roller 31 is rotatably arranged at the connecting portion between the attachment 51 and the chain 3.

The side chain guide 6 is a rail member arranged along a straight portion in the vertical direction of the chain 3. Specifically, the side chain guide 6 includes an inner rail 61 arranged on the inner peripheral side of the chain 3 and an outer rail 62 arranged on the outer peripheral side of the chain 3. The distance between the inner rail 61 and the outer rail 62 is set to a size that allows the chain roller 31 to be inserted.

The upper end of the side chain guide 6 is fixed to the drive frame 7, and the lower end of the side chain guide 6 is fixed to the driven frame 8. Since the driven frame 8 fluctuates up and down due to the expansion and contraction of the chain 3, the side chain guide 6 is configured to be able to follow the vertical fluctuation of the driven frame 8 by arranging a slide mechanism or the like at the seam.

When the chain roller 31 rotates along the arc portion of the upper sprocket 2 and enters the straight portion, it enters the gap between the inner rail 61 and the outer rail 62, and is guided by the side chain guide 6 to go straight in the vertical direction. Will be done.

Since the cage 5 is connected to the chain 3 in a state of being biased outward via the attachment 51, a force is applied to the chain 3 so that the chain 3 expands outward due to the load of the vehicle including the cage 5. However, by arranging the side chain guide 6, it is possible to suppress the bulge of the chain 3 to the outside, and the chain 3 can be rotated in a state of being restricted in the vertical direction.

Further, the vertical circulation type parking device 1 may include an intermediate frame 11 arranged between the drive frame 7 and the driven frame 8. On the intermediate frame 11, for example, a control panel 12 including a motor panel, a relay panel, a resistor, and the like is arranged. The intermediate frame 11 is fixed to the building via a space formed between the inner rails 61.

For example, if the vertical circulation parking device 1 before modification has a capacity of 35 vehicles and the weight limit of one vehicle is 1.6 tons, the cage 5 can accommodate a large vehicle with a middle roof or a high roof. Even if it is changed to 5, the weight limit cannot be increased due to the limitation of the strength of the chain 3. Therefore, even if there is a vacancy in the cage 5, the vehicle cannot be accommodated, or the number of cages 5 must be reduced at the time of remodeling. This is a factor that lowers the operating efficiency of the vertical circulation type parking device 1.

By the way, the take-up weight 83 described above generally has a weight of several tons. The take-up weight 83 is arranged to suppress the lifting of the lower sprocket 4, but if the lifting of the lower sprocket 4 can be suppressed by another method, the take-up weight 83 can be removed, and the number can be increased. Tons of weight can be devoted to vehicle containment.

For example, in the above-mentioned vertical circulation type parking device 1 before modification, when the take-up weight 83 is 3 tons, the weight limit of one vehicle can be increased to 1.9 tons for the cage 5 for 10 vehicles. Therefore, the operating efficiency can be improved accordingly.

Then, as shown in FIG. 2, the method of modifying the vertical circulation type parking device 1 according to the embodiment of the present invention is a guide member that guides the chain 3 to move along the lower outer circumference of the lower sprocket 4. Guide member addition step Step 1 to add 9, weight removal step Step 2 to remove the take-up weight 83, accommodation condition setting step Step 3 to set the accommodation conditions of the vehicle, and cage replacement to replace the cage 5 according to the accommodation conditions. The process Step 4 and the like are provided.

As shown in FIG. 1, the vertical circulation type parking device 1 includes a pair of upper sprockets 2 arranged at the upper part of the building and a pair of lower parts suspended from each of the upper sprockets 2 via a suspended chain 3. A sprocket 4, a driven frame 8 that rotatably supports the pair of lower sprockets 4, a take-up weight 83 arranged on the driven frame 8, and a side chain guide 6 that guides the vertical movement of the chain 3. It includes a plurality of cages 5 connected to the chain 3.

Guide member addition step Step 1 is, for example, a step of adding a guide member 9 as shown in FIG. 3B or FIG. Here, FIG. 3 is a diagram showing an example of a guide member, (A) shows the case where there is no guide member, and (B) shows the case where there is a guide member. FIG. 4 is a diagram showing a modified example of the guide member. In addition, in FIG. 3B and FIG. 4, the guide member 9 is painted in gray for convenience of explanation.

As shown in FIG. 3A, when the adjacent cage 5 is parallel to the outer circumference of the lower sprocket 4 in the absence of the guide member 9, the weight of the cage 5 and the vehicle is attached to the tip 51a of the attachment 51. Generates a vertically downward load W. Due to this load W, a moment that tends to rotate in the direction of the outer rail 62 is generated in the attachment 51.

Therefore, a force P in the direction away from the lower sprocket 4 acts on the tip 51b located above the attachment 51, and a force Q in the direction approaching the lower sprocket 4 acts on the tip 51c located below the attachment 51. It will be. By the resultant force of this force Q, a pushing force N that pushes up the lower sprocket 4 upward is generated.

The push-up force N becomes maximum when the adjacent cages 5 are parallel to each other on the outer circumference of the lower sprocket 4, as shown in the figure. Therefore, every time the chain 3 rotates and the cage 5 becomes parallel, a large pushing force N is generated, and the lower sprocket 4 vibrates up and down.

On the other hand, as shown in FIG. 3B, when the guide member 9 provided with the guide surface 91 to be moved along a part of the outer circumference of the lower sprocket 4 is arranged on the outer rail 62, the attachment 51 Since the chain roller 31 is arranged on the pin of the chain 3 to which the tip 51b of the above is connected, the chain roller 31 is supported by the guide member 9 even when a force P acts on the tip 51b of the attachment 51. , The reaction force R can be generated by the guide surface 91.

Therefore, the force Q generated at the tip 51c of the attachment 51 can be suppressed, the generation of the push-up force N can be suppressed, and the vibration of the lower sprocket 4 can be reduced. That is, as shown in the drawing, the guide member 9 may be formed to a range capable of supporting the chain roller 31 when the adjacent cage 5 is parallel to the outer circumference of the lower sprocket 4.

The guide member 9 shown in FIG. 3B is, for example, a plate material formed of a steel material, and has a shape in which a part of a rectangle is cut off by a part of a circle. The guide member 9 may be fixed to each of the outer rails 62 by welding, or may be fixed by fasteners such as bolts.

Further, as shown in FIG. 4, the guide member 9 may be connected between a pair of outer rails 62 facing each other with the lower sprocket 4 interposed therebetween. The guide member 9 shown in FIG. 4 is, for example, a plate material formed of a steel material and has a semicircular arc shape.

The guide member 9 is not limited to the configuration shown in FIGS. 3 (B) and 4, and can be used as a chain roller 31 when the adjacent cage 5 is parallel to the outer circumference of the lower sprocket 4. Other shapes may be used as long as they can be supported.

The weight removing step Step 2 is a step of removing the take-up weight 83 shown in FIG. The take-up weight 83 is, for example, a block made of cement. The block may be carried out of the building as it is, or it may be crushed and then carried out of the building.

The accommodation condition setting step Step 3 sets the accommodation number of large vehicles and the accommodation number of ordinary vehicles based on the capacity and weight limit of the vertical circulation type parking device 1 before modification and the weight of the removed take-up weight 83. It is a process.

In the cage replacement process Step 4, the cage of the vertical circulation type parking device 1 before modification is replaced with a cage 5 suitable for the cage based on the number of large vehicles and the number of ordinary vehicles set in the accommodation condition setting step Step 3. It is a process.

According to the above-described modification method of the vertical circulation type parking device 1 according to the present embodiment, the take-up weight 83 can be removed by adding the guide member 9, and the weight of the take-up weight 83 is addressed to the accommodation of the vehicle. It is possible to increase the weight limit of the accommodation vehicle.

It goes without saying that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.
