Description

  The present invention relates to an oil supply roller for supplying oil to a roller chain, and a manual oil supply device and an automatic oil supply device including the oil supply roller.

  Generally, for example, a roller chain is widely used for raising and lowering a pallet of a mechanical parking apparatus and raising and lowering an escalator. BACKGROUND ART Conventionally, there has been proposed an oil supply device for a roller chain, which has an oil sump inside and is provided with a shoe in which a valve is opened by coming into contact with a roller of a roller chain to supply oil from the oil sump (see Patent Document 1). . In this oil supply device, the valve is brought into contact with the roller of the roller chain to open the oil supply hole of the oil sump, but the lubricating oil is dripped from the oil supply hole to the roller chain.

JP, 2000-128338, A

  However, in the oil supply device for the roller chain described in Patent Document 1, the lubricating oil dropped from the oil supply hole does not return to the oil sump again, and when too many roller chains are dropped from the oil supply hole, the oil is excessive. Oil drips will occur. The lubrication position of the lubrication hole is a pin point position where drops can be made between the bush and roller and between the pin and bush.If the relative position between the lubrication device and the roller chain is misaligned, the roller chain will rotate and slide. I cannot refuel the part. That is, it is difficult to adjust the amount of oil supplied and the position of oil supply, and there is a problem in maintainability.

  Therefore, the present invention is made of polyurethane having a high oil impregnation property and is configured to be in contact with each member of the roller chain, thereby solving the problems described above, and a manual oil supply device and an automatic oil supply device including the oil supply roller. The purpose is to provide.

A first diameter part (93) capable of contacting the outer peripheral surface (101a) of the roller (101) of the roller chain (17b);
A second diameter part (94) capable of contacting the outer peripheral surfaces (103a, 105a) of the inner plate (103) and the outer plate (105) of the roller chain (17b);
A third diameter part (95) capable of contacting the outer surface (105b) of the outer plate (105),
The first diameter portion (93), the second diameter portion (94) and the third diameter portion (95) are made of polyurethane,
The first diameter portion (93) has a larger outer diameter than the second diameter portion (94) and a smaller outer diameter than the third diameter portion (95),
It is characterized by the following.

According to a second aspect of the present invention, a manual refueling device (80) comprises a refueling roller (85) according to any one of claims 1 to 3.
A frame portion (81) for holding the refueling roller (85),
It is characterized by the following.

According to a third aspect of the present invention, an automatic refueling device (35) comprises a refueling roller (29, 30) according to any one of claims 1 to 3.
An oil tank (33) for storing oil,
An oil supply pump (60) that pressure-feeds the oil stored in the oil tank (33) to the oil supply rollers (29, 30) according to a command from the control unit (46),
It is characterized by the following.

  It should be noted that the reference numerals in parentheses described above are in contrast to the drawings, but do not limit the configuration of the present invention in any way.

  According to the present invention, the first diameter portion, the second diameter portion, and the third diameter portion made of polyurethane come into contact with the roller, the inner plate, and the outer plate of the roller chain. Since polyurethane has a high oil impregnation property, excess oil attached to the roller chain returns to the polyurethane and the amount of oil supply can be easily adjusted. Further, the refueling roller comes into contact with a wide range including the roller of the roller chain, the inner plate and the outer plate, so there is no problem even if the refueling position is slightly displaced. For this reason, oil can be easily applied to the roller chain, and maintainability can be improved.

It is configured to slide over.

[lift device]
As shown in FIG. 3, the lifting device 9 has a fixed frame 10 arranged above the pallet 7 and having substantially the same front, rear, left, and right dimensions as the pallet 7, and a rear portion of the fixed frame 10 has a left-right direction. And a rotating shaft 12 that extends by and is rotated by the power of the drive motor 11 is rotatably supported. Two pairs of drive sprockets 13a, 13b, 15a, 15b are fixed to the left and right ends of the rotary shaft 12, and these two pairs of drive sprockets 13a, 13b, 15a, 15b have two pairs of roller chains 16a, 16b. , 17a, 17b are wound around each.

  The roller chains 16a, 16b, 17a, and 17b are pin links in which both ends of two link plates are connected by pins, and rollers in which both ends of two link plates are connected by bushes and rollers are loosely fitted in the bushes. The link and the link are alternately connected by inserting the pin into the bush, and can be bent freely by the many pin links and roller links, and one end 19a, 19b, 20a, 20b side thereof has a guide sprocket 21a. , 21b, 22a, 22b, and are connected to the front and rear sides (four corners) of the left and right ends of the pallet 7, respectively. That is, the roller chains 16a, 16b, 17a, 17b whose one ends 19a, 19b, 20a, 20b are connected to the four corners of the pallet 7 are hoisted or unwound by the same amount by the power of the drive motor 11, The pallet 7 can be moved up and down while maintaining the horizontal state.

  Below the two pairs of drive sprockets 13a, 13b, 15a, 15b, chain boxes 23, 25 for accommodating excess roller chains 16a, 16b, 17a, 17b when the pallet 7 is raised are arranged. Since the lifting device 9 is provided for each pallet 7, the roller chains 16a, 16b, 17a, 17b are also provided for each pallet 7.

  Further, oil supply roller units 26 and 27 for applying oil to the roller chains 16a, 16b, 17a and 17b are arranged above the two pairs of drive sprockets 13a, 13b, 15a and 15b. Since the oil supply roller units 26 and 27 have the same structure, only the oil supply roller unit 27 and its peripheral structure will be described below, and the description of the oil supply roller unit 26 side will be omitted.

[Refueling roller unit]
As shown in FIG. 4, the refueling roller unit 27 has refueling rollers 29 and 30 that can be engaged with the roller chains 17a and 17b, respectively, and a support unit 31 that rotatably supports the refueling rollers 29 and 30. It is connected to the oil tank 33 (see FIGS. 1 and 2) via the oil tube 32. The oil supply roller unit 27, the oil tube 32 and the oil tank 33 constitute an oil supply device 35 as an automatic oil supply device. Note that one oil supply roller unit or a plurality of oil supply roller units may be connected to one oil tank 33. Further, the oil tank 33 includes as many oil supply pumps 60 (see FIG. 7) as the number of connected oil supply roller units.

  As shown in FIGS. 5A and 5B, the support unit 31 of the oil supply roller unit 27 has a base bracket 36, side covers 37L and 37R, a pipe mounting base 38, and a shaft member 39. There is. The base bracket 36, the side covers 37L and 37R, and the pipe mounting base 38 are integrally assembled by a plurality of screws 40, and the upper surfaces and the side surfaces of the oil supply rollers 29 and 30 are covered by these. As a result, it is possible to prevent the refueling rollers 29, 30 from being exposed to sunlight, and reduce the oil contained in the refueling rollers 29, 30 and the deterioration of the refueling rollers 29, 30 themselves.

  A shaft member 39 is attached to the base bracket 36 by a hexagon nut 39a, and the oil supply rollers 29 and 30 are rotatably supported on the shaft member 39 with their side surfaces in close contact with each other. Further, a hole 36a and holes 36b, 36b arranged on both sides of the hole 36a are formed in the upper surface of the base bracket 36, and a sink plug 41 is attached to the hole 36a. The oil tube 32 is connected to the sunken plug 41, and the oil tube 32 is guided to the oil tank 33 by a wire guide or the like (not shown) provided on the pipe mounting base 38. The oil pressure-fed from the oil tank 33 via the oil tube 32 is dropped from the sink plug 41 to the oil supply rollers 29 and 30. The oil supply rollers 29, 30 are supported in a state where their side surfaces are in close contact with each other, and the oil is dripped onto this close contact portion.

  The sunken plugs 41 may be attached to the holes 36b and 36b, and the oil tubes 32 may be connected to the sunken plugs 41, respectively. As a result, oil can be dripped onto the respective oil supply rollers 29 and 30 at appropriate points, such as the axial positions that engage the roller chains 17a and 17b. Further, the oil dripped from the sink plug 41 may be configured not to be dripped, but to be applied to a wide range in the axial direction of the oil supply rollers 29, 30 via a brush or the like. Further, unlike the oil supply roller 85 described later in FIG. 15, the oil is not impregnated from the peripheral surfaces of the oil supply rollers 29 and 30, but is supplied to the oil reservoir formed inside the oil supply rollers 29 and 30. Good.

[control panel]
As shown in FIG. 1, FIG. 2 and FIG. 6, a control panel 45 is arranged on the rear side of the multi-story parking apparatus 1. As shown in FIG. 6, the control panel 45 has a PLC (Programmable Logic Controller) 46, a router 47, a terminal block 48, and an antenna 49. The PLC 46, the terminal block 48, and the antenna 49 are connected via the router 47, and various motors and various sensors are connected to the terminal block 48.

  FIG. 7 is a control block diagram of the present embodiment. The PLC 46 has a CPU 51, a ROM 52, a RAM 53, an I / O interface 54, a counter 55, and a timer 56, and the CPU 51 executes various programs stored in the ROM 52. The RAM 53 can temporarily store data and is used as a work area of the CPU 51. The CPU 51 exchanges data and signals with external parts and the like via the I / O interface 54. The counter 55 measures the number of operations of each pallet 7 and the number of refueling of the refueling device 35 corresponding to each pallet 7. The timer 56 measures the time when the oil supply device 35 corresponding to each pallet 7 refuels, the elapsed time from the last refueling time, the number of days elapsed, and the like.

  An inclination sensor 57, a temperature / humidity sensor 58, and a water level sensor 59 are connected to the input side of the PLC 46. The tilt sensor 57 can detect the tilt of the pallet 7 with respect to the horizontal plane. For example, when the tilt sensor 57 detects that the pallet 7 is greatly tilted due to a strong wind or the like while the pallet 7 is being moved up and down, the CPU 51 causes the pallet 7 to stop urgently. The temperature / humidity sensor 58 detects the temperature and humidity of the surrounding environment of the multi-level parking device 1. The water level sensor 59 is provided as an option and can detect the water level according to the mounting position on the multi-level parking device 1. For example, when the water level sensor 59 detects that the water level of the multi-level parking device 1 has reached a dangerous water level due to a typhoon or a high tide, the CPU 51 stops the operation of the pallet 7.

  Connected to the output side of the PLC 46 are a drive motor 11 for moving the pallet 7 up and down, an oil supply pump 60 for feeding oil to the oil supply roller unit 27, a motor (not shown) for slidingly moving the pallet 7, and the like. Has been done. Further, the PLC 46 is connected to the monitoring device 63 of the remote monitoring center 62 by using a public telephone line via the router 47 (see FIG. 6). The monitoring device 63 is composed of a personal computer, a workstation or the like, and has a storage device 64 such as a hard disk.

  The storage device 64 stores the operation data 65 transmitted from the PLC 46. The operation data 65 includes the number of operations of each pallet 7 measured by the counter 55, the number of times of refueling of the refueling device 35 corresponding to each pallet 7, the time of refueling of the refueling device 35 corresponding to each pallet 7 measured by the timer 56, And the time elapsed since the last refueling is included. In addition, the operation data 65 also includes durability data of each part, replacement history data and inspection history data, the number of occurrences of abnormality, the history of occurrence of abnormality, and the like. A monitor 66 such as a PC can be connected to the storage device 64 via a wired line or a wireless line, and the operation data 65 can be browsed by the monitor 66 or the setting of automatic refueling control described later can be changed. You can

[Automatic refueling control]
Next, the automatic refueling control according to the present embodiment will be described. The CPU 51 of the PLC 46 reads the program stored in the ROM 52 and repeatedly executes the following automatic refueling control for each pallet 7. Further, in the automatic refueling control, as shown in FIG. 8, when the automatic refueling control is started, the CPU 51 acquires operation data and weather data of each pallet 7 (step S1). The operation data to be acquired may be the operation data 65 stored in the storage device 64 on the monitoring center 62 side or the operation data measured by the counter 55 or the timer 56 on the PLC 46 side. The meteorological data may be data on the temperature, humidity and water level around the multi-level parking device 1 detected by the temperature / humidity sensor 58 and the water level sensor 59, or may be meteorological data acquired by the monitoring device 63 and transmitted to the PLC 46.

  Next, the CPU 51 determines whether or not the forced refueling command has been received from the monitoring device 63 (step S2). When it is determined that the forced refueling command has been received from the monitoring device 63 (step S2: YES), the CPU 51 starts refueling by the refueling device 35 and impregnates the refueling rollers 29 and 30 with oil (step S6). That is, the CPU 51 can operate the refueling device 35 based on the refueling command from the monitoring center 62.

  When it is determined that the forced refueling command is not received from the monitoring device 63 (step S2: NO), the CPU 51 determines whether or not the meteorological data satisfies the refueling start condition (step S3). The refueling start condition is, for example, when there is a forecast that it will rain within 24 hours from the present time, or when the humidity detected by the temperature / humidity sensor 58 exceeds 90%. This is because the multi-storey parking system 1 is basically installed by being exposed to the external environment, and therefore when there is rainfall, the oil supplied by the oil supply device 35 and the oil applied to the roller chains 17a, 17b is washed away. This is because it ends up. The refueling start condition can be arbitrarily changed by setting.

  When it is determined that the weather data does not satisfy the refueling start condition (step S3: NO), the automatic refueling control ends. When it is determined that the meteorological data satisfies the refueling start condition (step S3: YES), the CPU 51 sets the operation number after the last automatic refueling of the predetermined pallet 7 (hereinafter, simply referred to as the operation number) as a set value. It is determined whether or not has reached (step S4). When it is determined that the number of operations has reached the set value (step S4: YES), the process proceeds to step S6 described above.

  When it is determined that the number of operations has not reached the set value (step S4: NO), the CPU 51 causes the number of days elapsed since the last lifting / lowering operation of the predetermined pallet 7 (hereinafter, referred to as an operation interval) to reach the set value. It is determined whether or not (step S5). When it is determined that the operation interval has reached the set value (step S5: YES), the process proceeds to step S6 described above.

  When it is determined that the operation interval has not reached the set value (step S5: NO) and when step S6 is executed, the automatic refueling control ends. The above-described steps S4 and S5 are executed for each pallet 7 of the multi-story parking apparatus 1, and the set values for the number of operations and the operation interval are also set for each pallet 7.

  The output of the forced refueling command in step S2 and the change of the set values in steps S4 and S5 can be performed via the monitor 66 (see FIG. 7). As shown in FIG. 9, the monitor 66 can display a setting screen 70. On the setting screen 70, a palette status 71 is displayed for each palette. In the following, the palette number. The pallet situation 71 in 1 will be described as an example.

  Palette No. In the pallet status 71 of No. 1, an operating status display area 72, an automatic refueling setting button 73, a forced refueling command button 74, and a set value display area 75 are displayed. In the operation status display area 72, the time at which this pallet was last maintained by a service person, the number of automatic refueling operations performed by the refueling device 35 since the last maintenance, and a reset button for resetting the number of automatic refueling operations. And 76 are displayed.

  When the automatic refueling setting button 73 is pressed, the automatic refueling control can be switched on or off. On the setting screen 70, the palette number. Automatic refueling control is ON in all of 1 to 3. When the forced refueling command button 74 is pressed, refueling by the refueling device 35 can be started (see step S2 in FIG. 8).

  In the set value display area 75, an operation count setting change button 77, an operation interval setting change button 78, and a weather data condition change button 79 are displayed. When the operation number setting change button 77 is pressed, it is possible to change the set value of the operation number and turn off the automatic lubrication depending on the operation number. Palette No. In No. 1, automatic refueling according to the number of operations is OFF.

  When the operation interval setting change button 78 is pressed, it is possible to change the set value of the operation interval and turn off the automatic refueling according to the operation interval. When the weather data condition change button 79 is pressed, the setting of the refueling start condition based on the weather data in step S3 of FIG. 8 can be turned ON or OFF.

  That is, the weather data condition change button 79, the operation count setting change button 77, and the operation interval setting change button 78 are each set to OFF, so that each of steps S3 to S5 in FIG. 8 can be skipped. That is, if the weather data condition change button 79 is OFF, step S3 is YES, if the operation number setting change button 77 is OFF, step S4 is NO, and if the operation interval setting change button 78 is OFF, step S5 is It becomes NO.

  Next, a specific example of the automatic refueling control will be described. 10A to 10C are pallet No.s shown in FIG. It is a graph which shows the lubrication timing of automatic lubrication control in each set value of 1-3. As shown in FIG. 10A, the pallet No. When the set value of 1 is set, that is, the automatic refueling according to the number of operations is OFF and the set value of the operation interval is set to 5 days, the pallet No. Automatic refueling is performed by the refueling device 35 every five days regardless of the number of times of operation of 1. For example, for a pallet whose operating rate is not so high, the pallet No. It is preferable to set a set value such as 1.

  As shown in FIG. 10B, the pallet No. When the set value of 2, that is, the set value of the number of operations is 10 times and the automatic lubrication according to the operation interval is set to OFF, the pallet No. Regardless of the second operation interval, the automatic refueling is performed by the refueling device 35 every 10 lifting operations. For example, for a pallet with a very high operating rate, the pallet No. It is preferable to set a set value such as 2.

  Further, as shown in FIG. When the set value of No. 3, that is, the set value of the number of operations is set to 5 and the set value of the operation interval is set to 10 days, the palette No. The automatic refueling is performed by the refueling device 35 every 5 times ascending / descending operation from the last automatic refueling in 3 and every 10 days from the last automatic refueling.

  More specifically, at time t1, the pallet No. is set before the operation interval reaches 10 days. Since the lifting and lowering operation of 3 was performed 5 times, automatic lubrication was performed. At time t2, the pallet No. Since the operation interval was 10 days before the No. 3 lifted / lowered 5 times, it was automatically refueled. Thereafter, the same is true at times t3 to t5.

  Here, the pallet No. The pallet No. 1 is the first pallet P1, the pallet No. The second pallet P2 is the second pallet P2, the first pallet P1 is a roller chain that moves up and down, and the first chain C1 is a roller chain that is driven independently of the first chain C1 to move the second pallet P2 up and down. The refueling device 35 that refuels the first chain C1 is referred to as a first refueling unit F1, and the refueling device 35 that refuels the second chain C2 is referred to as a second refueling unit F2. The automatic oil supply system in the present embodiment has at least a first oil supply section F1, a second oil supply section F2 and a PLC 46. The PLC 46 as the control unit of the present embodiment is configured so that the monitoring center 62 can monitor the operation data of the first pallet P1 and the second pallet P2 so that the operation information of the first pallet P1 and the second pallet P2 can be monitored. Information) is transmitted to the monitoring center 62.

  Then, as described with reference to FIGS. 10A and 10B, the PLC 46 controls the first refueling portion F1 so that the first chain C1 is refueled based on the operation data of the first pallet P1. Further, the PLC 46 controls the second oil supply section F2 so that the second chain C2 is supplied with oil based on the operation data of the second pallet P2. In this way, since each chain (C1, C2) is refueled according to the operation data for each pallet, even if the operating rates of the first pallet P1 and the second pallet P2 vary, refuel at appropriate timing. You can

  In addition, a set value of the number of operations for the first pallet P1 (first number), a set value of the operation interval (first number of days), and a set value of the number of operations for the second pallet P2 (second number) and a set value of the operation interval. The (second number of days) can be changed on the monitoring center 62 side via the monitor 66. Therefore, it is possible to set an appropriate set value according to the operating status of the monitored first pallet P1 and second pallet P2.

  With such automatic refueling control, it is possible to automatically refuel the refueling rollers 29 and 30 and apply oil to the roller chains 17a and 17b without sending a service person to the location of the multi-story parking apparatus 1. Therefore, the labor cost of the service person can be reduced, and maintenance of the multi-story parking apparatus 1 can be performed inexpensively and easily.

  In addition, the set values and conditions for executing automatic lubrication can be arbitrarily changed according to the number of operations for each pallet, the operation interval, and the installation environment, so that an appropriate amount of oil can be applied to the roller chains 17a and 17b. It can be carried out. That is, it is possible to reduce the occurrence of rust and sticking of the roller chains 17a and 17b due to lack of oil, and to reduce oil dripping due to excess oil.

  Further, in the present embodiment, oil is supplied to the oil supply rollers 29, 30 by the oil supply device 35. However, for example, when the oil is directly dropped on the roller chains 17a, 17b, the oil is supplied to the stopped roller chains 17a, 17b. On the other hand, the oil can be supplied only at one location, which causes uneven coating and causes oil dripping. However, in the present embodiment, first, since the oil supply rollers 29, 30 are impregnated with oil and the oil supply rollers 29, 30 retain the oil, even if the roller chains 17a, 17b are stopped at the time of oil supply, When the pallet 7 moves up and down and the roller chains 17a and 17b are driven, the oil held by the roller chains 17a and 17b can be applied to the roller chains 17a and 17b over a wide range. Thereby, oil dripping and application unevenness can be reduced. Further, since the oil can be distributed to the roller chains 17a and 17b by supplying a small amount of oil, the maintenance cost can be reduced.

  The remaining amount of oil in the oil tank 33 may be calculated from the number of operations of the pallet 7 and the number of times of automatic refueling by the refueling device 35, and the cycle of replacement of the oil tank 33 or replenishment of oil may be calculated.

[Automatic lubrication area and manual lubrication area]

FIG. 11A shows a state in which the pallet 7 is located at a fixed position on the fourth floor, and FIG. 11B shows a state in which the pallet 7 is landed on the first floor. In the following description, only the left and right roller chains 17a and 17b for moving the pallet 7 up and down and the refueling roller unit 27 will be described, and the description of the other left and right roller chains 16a and 16b and the refueling roller unit 26 will be omitted.

  In the two-stage multi-level parking apparatus, roller chains 17a and 17b for raising and lowering the pallet 7 are connected to the pallet 7 at one ends 20a and 20b and are housed in the chain box 25 at the other end. Then, as shown in FIG. 11A, when the pallet 7 is located at the highest position such as the fixed position on the 4th floor, the areas of the roller chains 17a and 17b that are fed out from the chain box 25 are Few. On the other hand, as shown in FIG. 11 (b), when the pallet 7 is located at the lowest position such as the landing position on the first floor, the roller chains 17 a and 17 b that are fed out from the chain box 25 are not moved. There are many areas.

  In the roller chains 17a and 17b in which the feeding operation is performed in this manner, an area where oil can be applied to the roller chains 17a and 17b by the oil supply roller unit 27 (hereinafter, referred to as an automatic oil supply area) and a roller by the oil supply roller unit 27 are used. It is divided into an area where oil cannot be applied to the chains 17a and 17b (hereinafter referred to as a manual oil supply area). In FIGS. 11 (a) and 11 (b), the dashed line indicates the automatic lubrication region as the first region, and the two-dot chain line indicates the manual lubrication region as the second region. The manual refueling region corresponds to a region of the roller chains 17a, 17b at one end 20a, 20b side of the refueling roller unit 27 when the pallet 7 is located at the highest position. In other words, the manual refueling area is located closer to the pallet 7 than the automatic refueling area in the traveling direction of the roller chains 17a and 17b.

  The automatic refueling area is a particularly high place in a three- and four-tiered mechanical parking system, and it does not have a good footing. It is a dangerous work especially at night or on a windy day. There was a problem with safety. However, in the present embodiment, since the oil supply device 35 can automatically supply oil, the safety is improved and the roller chains 17a and 17b can be easily maintained.

  In the case of the four-story multi-storey parking device 1 as in the present embodiment, for example, the manual lubrication areas of the roller chains 17a and 17b are 2000 mm and 3500 mm, respectively. Since oil cannot be applied by the oil supply roller unit 27 to these manual oil supply areas, a serviceman manually supplies oil by using the manual oil supply device 80. In the refueling method for the two-stage parking apparatus to which the present embodiment is applied, the automatic refueling process is performed by the refueling device 35 as an automatic refueling device, and the manual refueling region is refueled by the manual refueling device 80. And a manual refueling process.

The oil tank 89 may be attached to the shoulder or the like of a service person by attaching a strap or the like.

[Refueling roller]
Next, the configuration and shape of the oil supply rollers 85 and 86 will be described in detail, but since the oil supply rollers 85 and 86 have the same shape, only the oil supply roller 85 will be described. Further, an example will be described in which the oil supply roller 85 slides on the roller chain 17b to supply oil. As shown in FIG. 13, the oil supply roller 85 has a base layer 300 in which an oil reservoir 113 (see FIG. 15) is provided inside the urethane layer 200, and a urethane layer 200 that constitutes the outer peripheral surface and is made of polyurethane. ing. The urethane layer 200 is arranged on the outer side in the radial direction of the base layer 300 and is rich in oil impregnation and excellent in conformability. Therefore, excess oil adhering to the roller chain 17b returns to the urethane layer 200 made of polyurethane to supply oil. The amount can be adjusted easily. Further, as will be described later, due to the shape of the urethane layer 200, the urethane layer 200 contacts a wide range including the roller 101, the inner plate 103, and the outer plate 105 of the roller chain 17b, so there is no problem even if the refueling position is slightly displaced. It is possible to lubricate each element of the roller chain 17b with oil. Further, the urethane layer 200 has excellent wear resistance and can withstand long-term use.

  The urethane layer 200 of the oil supply roller 85 has a medium diameter portion 93 as a first diameter portion located at the center in the axial direction and a small diameter portion 94 as a second diameter portion positioned on both outer sides of the middle diameter portion 93 in the axial direction. , 94 and large diameter portions 95, 95 as third diameter portions located on both outer sides of the small diameter portions 94, 94 in the axial direction. The medium diameter portion 93, the small diameter portions 94, 94, and the large diameter portions 95, 95 are each formed in a cylindrical shape, and are formed between the medium diameter portion 93 and the small diameter portion 94 and between the small diameter portion 94 and the large diameter portion 95. Steps are formed between the two. The medium diameter portion 93 has a larger outer diameter than the small diameter portion 94 and has a smaller outer diameter than the large diameter portion 95.

  As shown in FIG. 14, the roller chain 17b includes a plurality of pairs of inner plates 103 and 103 connected by bushes 102 into which the rollers 101 are loosely fitted, and a plurality of pairs of outer plates connected by pins 104 inserted into the bushes 102. And plates 105, 105. The outer peripheral surface 93a of the middle diameter portion 93 of the oil supply roller 85 is configured to be capable of contacting the outer peripheral surface 101a of the roller 101, and the outer peripheral surface 94a of the small diameter portion 94 includes the outer peripheral surfaces 103a of the inner plate 103 and the outer plate 105. It is configured to be able to contact 105a.

  Further, the side surface 93b of the middle diameter portion 93 is configured to be able to contact the inner side surface 103b of the inner plate 103, and the inner side surface 95a of the large diameter portion 95 is configured to be able to contact the outer side surface 105b of the outer plate 105. ing. 14 and 15, each element of the roller chain 17b and the refueling roller 85 are illustrated with a slight gap, but the refueling roller 85 is provided with a tension spring 87 (see FIG. 12). Since they are elastically deformed by the force, these elements come into contact with the oil supply roller 85 when oil is applied.

  As shown in FIG. 15, the base layer 300 of the oil supply roller 85 accommodates a base member 110 made of metal or the like inside, and the base member 110 includes bearings 111 and 111 and shafts of the bearings 111 and 111. The seal members 112, 112 arranged outside in the direction are attached. The base member 110 forms an oil sump 113 capable of accumulating oil between the bearings 111, 111 in the axial direction, and the oil sump 113 has the urethane layer 200 of the oil supply roller 85 via the communication holes 114, 114. Is in communication with.

  Since the manual lubrication device 80 is configured as described above, when applying oil to the manual lubrication area of the roller chain 17b using the manual lubrication device 80, the serviceman first determines the height according to the manual lubrication height. , The length of the frame portion 81 is adjusted. Then, by pulling the trigger portion 82a of the handle portion 82, the nip between the oil supply rollers 85 and 86 is opened, and the roller chain 17b is held between the oil supply rollers 85 and 86. Once the roller chain 17b is sandwiched by the oil supply rollers 85 and 86, the tension spring 87 causes the oil supply rollers 85 and 86 to sandwich the roller chain 17b with a constant clamping pressure. The urging force of the tension spring 87 is set in advance so that the amount of oil that oozes out from the oil supply rollers 85 and 86 becomes an appropriate amount.

  The serviceman grasps the manual pump 91 to appropriately feed the oil from the oil tank 89 to the oil supply rollers 85 and 86. At this time, the pressure-fed oil is carried to the oil sump 113 inside the oil supply rollers 85 and 86, the oil leaks from the communication holes 114 and 114 from the oil sump 113, and the oil supply rollers 85 and 86 become oil. Impregnate. The hole diameters of the communication holes 114, 114 are set so that an appropriate amount of oil leaks from the oil sump 113 to the oil supply rollers 85, 86.

  As a result, no special skill is required to operate the manual pump 91 by a service person, and an appropriate amount of oil can be easily included in the oil supply rollers 85 and 86. In addition, the holding pressure of the oil supply rollers 85 and 86 is made constant by the tension spring 87, so that the manual oil supply device 80 can easily apply the oil to the roller chain 17b. Also, oil dripping can be reduced.

  Further, the oil supply rollers 85 and 86 are inserted between the inner plates 103 and 103 of the roller chain 17b and come into contact with the outer peripheral surface 101a of the roller 101 and the inner side surface 103b of the inner plate 103 to apply the oil. have. For this reason, it is possible to appropriately supply oil between the roller 101 and the inner plate 103, which require oil supply in particular.

  Further, in the oil supply rollers 85 and 86, the side surface 93 b of the medium diameter portion 93, the outer peripheral surface 94 a of the small diameter portion 94 and the inner side surface 95 a of the large diameter portion 95 form a recess 120 (see FIG. 14), and the recess 120 It is configured to cover the inner plate 103 and the outer plate 105. As a result, it is possible to appropriately refuel between the inner plate 103 and the outer plate 105 that require refueling, and the outer surface 105 b of the outer plate 105. When oil is applied to the outer side surface 105b of the outer plate 105, the finish is good.

  As described above, due to the shapes of the oil supply rollers 85 and 86 and the configuration of the manual oil supply device 80, an appropriate amount of oil can be easily applied to the roller chain 17b at an appropriate position. Further, by adjusting the length of the frame portion 81 of the manual lubrication device 80, it is possible to easily refuel at a high place, so that even the chain of the uppermost pallet does not go up the frame body 6. Can be refueled from above ground.

  Further, since the automatic lubrication area of the roller chain 17b can be refueled by the lubrication device 35, the area where the serviceman himself manually refuels is significantly reduced, and the maintenance time and cost can be reduced. Further, since the oil supply device 35 refuels the roller chains that raise and lower each pallet according to the operating status of each pallet, it refuels the pallet with a high operating rate at a high frequency and the pallet with a low operating rate at a low frequency. Therefore, it is possible to apply an appropriate amount of oil to each pallet that varies in usage frequency. As a result, it is possible to reduce the occurrence of rust and sticking of the roller chain 17b due to the lack of oil, and to reduce the oil dripping due to excess oil.

  In this embodiment, the manual oil supply device 80 is composed of the frame portion 81, the handle portion 82, the oil application portion 83, and the oil supply portion 84, but is not limited to this. For example, the handle portion 82 and the oil supply portion 84 may be omitted and the frame portion 81 and the oil application portion 83 may constitute the manual oil supply device 80. In this case, the oil supply roller 85 may be added with oil by being directly immersed in the oil contained in the bucket or the like. Further, the configuration of the oil application section 83 is only required to have the support arm 83a and the oil supply roller 85 as a minimum, and other members may be appropriately added or omitted.

  Further, in the present embodiment, refueling rollers 85 and 86 are divided into urethane layer 200 and base layer 300, but the present invention is not limited to this, and may be constituted by only urethane layer 200, for example. Further, the description has been given by taking as an example the above-ground type ascending / descending type multilevel parking device having a four-row structure with four rows above the ground, but the invention is not limited to this. For example, the present invention can be applied to an up-and-down type multi-level parking device that does not perform a traverse operation. Further, the number of stages and the number of rows are not limited, and the present invention can be applied to not only the ground type or the pit type.
