Description

TECHNICAL FIELD The present invention relates to a modification method for a vertical circulation parking system, and more particularly to a modification method suitable for a vertical circulation parking system having a take-up weight.

A multilevel parking system is known as a facility for parking as many vehicles as possible in a limited site. This multi-storey parking system includes a horizontal circulation type parking system in which a pallet on which a vehicle is placed is moved back and forth and to the left and right to store it in an empty space, and a pallet on which a vehicle is placed is raised and lowered and stored in the left and right shelves of the hoistway. There are an elevator type parking system, a vertical circulation type parking system in which a cage on which a vehicle is placed is vertically circulated and accommodated, and the like. Among these parking systems, the vertical circulation type parking system has the advantage of being the simplest in structure and less likely to fail.

In recent years, with the diversification of functions mounted on vehicles and the increase in size of vehicles, vehicle weight tends to increase. In the case of such a vertical circulation parking system, there is an upper limit to the allowable weight due to the strength of the chain due to the structure in which the cage is connected to the chain for circulating transportation. As a result, existing facilities cannot accommodate heavy vehicles or limit the number of vehicles that can be accommodated.

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

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 a guide member.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. FIG. Here, FIG. 1 is an overall schematic diagram showing the vertical circulation parking system before modification. FIG. 2 is a flowchart showing a method for modifying a vertical circulation parking system according to one embodiment of the present invention.

First, the overall configuration of the vertical circulation parking system 1 before modification will be described with reference to FIG. A vertical circulation parking system 1 comprises a pair of upper sprockets 2 arranged in the upper part of a building (not shown), and a pair of lower sprockets 4 respectively suspended from the upper sprockets 2 via suspended chains 3. , a plurality of cages 5 connected to the chain 3 via attachments 51, and side chain guides 6 for guiding the vertical movement of the chain 3.

The upper sprocket 2 is rotatably supported by a drive frame 7 fixed to the building. Also, the pair of upper sprockets 2 are arranged outside of 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 rotating the upper sprocket 2 is arranged on the girder 72 . The drive means 73 is configured by, for example, a drive motor, a speed reducer, and the like. The side frame 71 rotatably supports the upper sprocket 2 and the reduction gear, and is connected to the upper end of the side chain guide 6 . Note that the configuration of the drive frame 7 is not limited to the illustrated configuration.

The chain 3 is an endless ring-shaped chain that is looped around one upper sprocket 2 and one lower sprocket 4 positioned therebelow. When the upper sprocket 2 is rotationally driven by the drive means 73, the chain 3 rotates. The chain 3 also has a plurality of chain rollers 31 guided by the side chain guides 6 .

The lower sprocket 4 is held in a suspended state by a chain 3 wound around the upper sprocket 2. - 特許庁The lower sprocket 4 is a driven sprocket that is rotationally driven by the rotation of the chain 3 . A pair of lower sprockets 4 are connected by a driven frame 8 and 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 depending on the number of vehicles placed on the cage 5 , the driven frame 8 must follow the expansion and contraction of the chain 3 . The follower frame 8 is therefore, unlike the drive frame 7, not fixed to the building.

The frame structure 82 is composed of, for example, flat plate frames arranged vertically, a connection frame that connects the flat plate frames, braces as reinforcing members, and the like. A take-up weight 83 is arranged on the frame structure 82 to suppress the lifting of the lower sprocket 4 . The side frame 81 rotatably supports the lower sprocket 4 and is connected to the lower end of the side chain guide 6 . Note that the structure of the driven frame 8 is not limited to the illustrated structure.

The cage 5 is a cage on which the vehicle is placed. In FIG. 1, for convenience of explanation, only two cages 5 positioned above and below are shown, and other cages are omitted. The cage 5 is connected to the chain 3 via a V-shaped attachment 51 . Specifically, the attachment 51 has two ends on the open side of the V shape connected to the chain 3 , and one end on the closed side of the V shape connected to the cage 5 . 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 the vertical straight portion 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 space between the inner rail 61 and the outer rail 62 is set to a size that allows the chain roller 31 to pass through.

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 moves up and down due to the extension and contraction of the chain 3, the side chain guide 6 is configured to follow the vertical movement of the driven frame 8 by arranging a slide mechanism or the like at the joint.

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 so as to move straight up and down. be done.

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

The vertical circulation parking system 1 may also include an intermediate frame 11 arranged between the driving frame 7 and the driven frame 8 . A control panel 12 including, for example, a motor panel, a relay panel, resistors, and the like is arranged on the intermediate frame 11 . The intermediate frame 11 is fixed to the building via spaces formed between the inner rails 61 .

For example, if the number of vehicles that can be accommodated in the vertical circulation parking system 1 before modification is 35 and the weight limit for one vehicle is 1.6 tons, the cage 5 is a cage that can accommodate a large vehicle with a middle roof or a high roof. Even if it is changed to 5, the limit weight cannot be increased due to the limitation of the strength of the chain 3. Therefore, even if there is space in the cages 5, the vehicle cannot be accommodated, and the number of cages 5 must be reduced when remodeling. This becomes a factor of lowering the operating efficiency of the vertical circulation parking system 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 of Tonnes of weight can be devoted to vehicle accommodation.

For example, if the take-up weight 83 is 3 tons in the above-described vertical circulation parking system 1 before modification, the weight limit per vehicle for ten cages 5 can be increased to 1.9 tons. , the operating efficiency can be improved accordingly.

As shown in FIG. 2, the modification method of the vertical circulation parking system 1 according to the embodiment of the present invention includes a guide member that guides the chain 3 to move along the lower outer periphery of the lower sprocket 4. 9, a weight removal step Step 2 for removing the take-up weight 83, an accommodation condition setting step Step 3 for setting the accommodation conditions of the vehicle, and a cage exchange for exchanging the cage 5 according to the accommodation conditions. and a process Step4.

As shown in FIG. 1, the vertical circulation parking system 1 comprises a pair of upper sprockets 2 arranged on the upper part of the building and a pair of lower sprockets suspended from the upper sprockets 2 via suspended chains 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, a side chain guide 6 that guides the vertical movement of the chain 3, a plurality of cages 5 connected to the chain 3.

The guide member adding step Step 1 is a step of adding a guide member 9 as shown in FIG. 3B or FIG. 4, for example. Here, FIG. 3 is a diagram showing an example of the guide member, (A) shows the case without the guide member, and (B) shows the case with the guide member. FIG. 4 is a diagram showing a modification of the guide member. In addition, in FIGS. 3B and 4, for convenience of explanation, the guide member 9 is painted out in gray.

As shown in FIG. 3A, without the guide member 9, when the adjacent cages 5 are parallel to each other on the outer periphery of the lower sprocket 4, the weight of the cage 5 and the vehicle is applied to the tip 51a of the attachment 51. causes a vertically downward load W. This load W causes the attachment 51 to generate a moment to rotate in the direction of the outer rail 62 .

Therefore, a force P in the direction away from the lower sprocket 4 acts on the tip 51b positioned above the attachment 51, and a force Q in the direction approaching the lower sprocket 4 acts on the tip 51c positioned below the attachment 51. It will happen. A resultant force of this force Q generates a pushing force N that pushes the lower sprocket 4 upward.

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

On the other hand, as shown in FIG. Since the chain roller 31 is arranged on the pin of the chain 3 to which the tip 51b of the attachment 51 is connected, the chain roller 31 is supported by the guide member 9 even when the force P acts on the tip 51b of the attachment 51. , a 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 pushing force N can be suppressed, and the vibration of the lower sprocket 4 can be reduced. In other words, the guide member 9 may be formed to the extent that it can support the chain roller 31 when the adjacent cages 5 are parallel on the outer circumference of the lower sprocket 4, as shown in the figure.

The guide member 9 shown in FIG. 3B is, for example, a plate member made of steel, and has a shape obtained by cutting a part of a rectangle with 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.

Moreover, as shown in FIG. 4, the guide member 9 may be configured to 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 member made of steel and has a semicircular arc shape.

Note that the guide member 9 is not limited to the configuration shown in FIGS. Other shapes are possible as long as they are of a supportable configuration.

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 cemented block. The blocks may be carried out of the building as they are, or may be crushed and then carried out of the building.

In the accommodation condition setting process Step 3, the accommodation number of large vehicles and the accommodation number of ordinary vehicles are set based on the number of accommodation vehicles and the weight limit of the vertical circulation parking system 1 before remodeling 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 parking system 1 before remodeling is replaced with a cage 5 suitable for the number of large vehicles and the number of ordinary vehicles set in the accommodation condition setting process Step 3. It is a process.

According to the modification method of the vertical circulation parking system 1 according to the present embodiment described above, the take-up weight 83 can be removed by adding the guide member 9, and the weight of the take-up weight can be used to accommodate the vehicle. and increase the weight limit of the accommodated vehicle.

The present invention is not limited to the above-described embodiments, and various modifications are possible without departing from the scope of the present invention.
