Description

Technical Field

[0001] The implementation mode of the utility model relates to a hanging basket device. Background Art

[0002] The hanging basket used in the operation in the elevator shaft formed in the building generally includes a car, a wire rope for suspending the car, a hoist installed on the floor surface of the car, and a control cabinet for driving the hoist. The hanging basket rises or falls in the shaft by winding the wire rope with the hoist. Power supply equipment such as a power distribution cabinet is arranged above the building. The hoist is connected to the power supply equipment via a tail line. Thus, power can be supplied to the hoist to drive the hoist.

[0003] However, laying and removing the tail wire requires a lot of labor and time. In addition, the tail wire may damage the safety of the operation. For example, if the tail wire is entangled with the equipment in the hoistway, it may damage the equipment.

[0004] In addition, when there is no power supply equipment in the building, a generator is sometimes used to supply power to the hoist. However, in this case, various problems arise. For example, the preparation and operation of the generator require expenses. In addition, a large amount of carbon dioxide is emitted along with the operation of the generator.

[0005] In order to solve such a problem, it is also considered to mount a battery device including a rechargeable battery in the car to supply electric power to the hoisting machine.

[0006] However, in this case, a large and heavy battery device needs to be mounted in the car. If a large battery device is installed in the car, the working space in the car is compressed. In addition, a heavy battery device needs to be installed in consideration of the weight balance of the car to prevent the car from tilting. Therefore, it is difficult to install the battery device in a way that does not hinder the work of the operator in the car.

[0007] Considering such a problem, in JP6261800B1, a battery device (battery, auxiliary battery, etc.) is arranged on the left and right outer sides of the car. However, when such a hanging basket device is applied to an elevator shaft, the left and right dimensions of the car need to be reduced. In addition, the battery device will hinder access to the work object from the car, and the work may become difficult. Utility Model Content

[0031] The hanging basket device of this embodiment comprises: a car; a hoisting machine fixed to the car and winding a wire rope suspending the car; a driving device including a rechargeable battery and driving the hoisting machine; and an underfloor shelf arranged below the car and supporting at least a portion of the driving device.

[0032] Hereinafter, embodiments of the hanging basket device of the present invention will be described with reference to the accompanying drawings. Figure 1 1 is a perspective view of a hanging basket device 5 according to an embodiment of the present invention. Figure 1 In the example shown, the hanging basket device 5 is used for installation of an elevator device and is arranged in the hoistway 1 of the elevator.

[0033] The hanging basket device 5 includes a car 10, a pair of hoists 20a, 20b, a driving device 40 for driving the hoists 20a, 20b, and an underfloor rack 50. The car 10 has a staircase opening 11 on its side. An operator can enter the car 10 through the staircase opening 11, and can also exit the car 10 through the staircase opening 11. In the example shown in the figure, the hanging basket device 5 also has a ceiling 6. The ceiling 6 is arranged above the car 10 to protect the operator on the car 10 from falling objects.

[0034] In the following description, the direction in which the operator exits the car 10 is called the front direction, the direction in which the operator enters the car 10 is called the rear direction, and the vertical direction is called the up-down direction. In addition, the direction orthogonal to the front-back direction and the up-down direction is called the left-right direction.

[0035] A pair of first wire ropes 2a and 2b are suspended in the hoistway 1. The pair of first wire ropes 2a and 2b are separated from each other in the left-right direction.

[0036] A pair of hoists 20a and 20b are provided in the car 10. The pair of hoists 20a and 20b are separated from each other in the left-right direction. The first wire rope 2a on the right side is wound around the hoist 20a on the right side, and the first wire rope 2b on the left side is wound around the hoist 20b on the left side. In the illustrated example, the hoists 20a, 20b and the first wire ropes 2a and 2b constitute an endless-winder. That is, the lower ends of the first wire ropes 2a and 2b wound around the hoists 20a and 20b hang down below the hanging basket device 5. If the hoists 20a and 20b are driven by the driving device 40, the first wire ropes 2a and 2b are wound around the hoists 20a and 20b. Thus, the hanging basket device 5 is raised and lowered.

[0037] In the illustrated example, the hanging basket device 5 also has a pair of anti-falling devices 30a, 30b. The anti-falling devices 30a, 30b are arranged on the right side and the left side of the car 10. A pair of second steel wire ropes 3a, 3b are suspended in the hoistway 1. The pair of second steel wire ropes 3a, 3b are separated from each other in the left and right directions. The second steel wire rope 3a on the right passes through the anti-falling device 30a on the right. The second steel wire rope 3b on the left passes through the anti-falling device 30b on the left. If an abnormality occurs in the hoist 20a, 20b or the first steel wire rope 2a, 2b and the hanging basket device 5 starts to fall, the anti-falling devices 30a, 30b grasp the corresponding second steel wire ropes 3a, 3b to prevent the hanging basket device 5 from falling.

[0038] In addition, the hanging basket device 5 also has two pairs of roller guides 7a and 7b. The roller guides 7a and 7b are arranged below and above the right side and left side of the car 10. The pair of roller guides 7a on the right side is pressed against one of a pair of guide rails (not shown) extending in the vertical direction in the hoistway 1. The pair of roller guides 7b on the left side is pressed against the other of the pair of guide rails. The hanging basket device 5 is raised and lowered along the guide rails. Thereby, the swing of the hanging basket device 5 is prevented, and the posture of the hanging basket device 5 is stabilized. In addition, the guide rail is a guide rail for elevators, and is installed in the hoistway 1 using the hanging basket device 5. Therefore, in the initial stage of the operation using the hanging basket device 5, the guide rail does not exist in the hoistway 1. Therefore, the hanging basket device 5 needs to be able to maintain a certain degree of posture for lifting and lowering even without the guide rail.

[0039] Next, the car 10 will be described. The car 10 includes a floor portion 12 and a handrail 14 erected on the floor portion 12 .

[0040] The floor portion 12 supports the operator in the car 10 from below. In the example shown in the figure, a pair of hoists 20a and 20b are fixed to the floor portion 12. The floor portion 12 is a quadrilateral as a whole, and has edges 12a to 12d. The edges 12a and 12b extend in the front-to-back direction. The edges 12a and 12b are the right edge and the left edge of the floor portion 12, respectively. The edges 12c and 12d extend in the left-right direction. The edges 12c and 12d are the rear edge and the front edge of the floor portion 12, respectively.

[0041] By comparison Figure 2A to Figure 2C It is understood that the floor portion 12 can be extended in its rear area. Figure 2A In the example shown, the floor panel 13a forms the floor portion 12. Figure 2B In the example shown, the floor panel 13a and the additional floor panel 13b form the floor panel portion 12. The additional floor panel 13b is connected to the rear edge of the floor panel 13a. Figure 2C In the example shown, the floor panel 13a and the additional floor panels 13b and 13c form the floor panel portion 12. The additional floor panel 13c is connected to the rear edge of the additional floor panel 13b. Figure 2A to Figure 2C In either case, the hoists 20a, 20b are fixed to the same position on the floor 13a.

[0042] The handrail 14 has first to fourth pillars 14a to 14d and crossbeams 15a to 15c. The first to fourth pillars 14a to 14d are erected at the four corners of the floor portion 12. The crossbeams 15a to 15c extend along the right edge 12a, the left edge 12b and the rear edge 12c of the floor portion 12 between the adjacent pillars 14a to 14d. A staircase entrance 11 is formed between the right crossbeam 15a and the left crossbeam 15b (in other words, above the front edge 12d of the floor portion 12). A door 16 is provided at the staircase entrance 11. The right crossbeam 15a and the left crossbeam 15b are opposite to each other in the left-right direction, and the rear crossbeam 15c and the door 16 are opposite to each other in the front-back direction. The floor portion 12, the crossbeams 15a to 15c, the door 16 and the ceiling 6 define a work area for the operator. The operator can enter the work area through the entrance 11 and can also exit the work area through the entrance 11 .

[0043] The entrance 11 of the car 10 is arranged facing the wall 1a of the wall constituting the hoistway 1, which is formed with the entrance 4 of the elevator. Thus, the operator can get on the car 10 from the entrance 4 of the elevator, and can go down from the car 10 to the entrance 4 of the elevator (thus going down to the elevator hall).

[0044] like Figure 3As shown, the drive device 40 includes a battery cabinet 41, an inverter cabinet 45, and an operation cabinet 47. The battery cabinet 41 includes a rechargeable battery 42, a charging connector 43, and a battery control unit 44. The rechargeable battery 42 is charged by connecting the charging connector 43 to a charger (not shown). The battery control unit 44 controls the charging and discharging of the rechargeable battery 42.

[0045] The inverter cabinet 45 includes a battery inverter 46 . The battery inverter 46 converts the electric power output from the rechargeable battery 42 into electric power suitable for driving the operation cabinet 47 and supplies the electric power to the operation cabinet 47 .

[0046] The operating cabinet 47 has a pair of motor inverters 48a and 48b. Each motor inverter 48a and 48b converts the power supplied from the battery inverter 46 into power suitable for driving the hoist 20a and 20b and supplies it to the hoist 20a and 20b. A switch 49 is connected to each motor inverter 48a and 48b. The operator uses the switch 49 to issue a command for the lifting action, thereby flowing a driving current from the motor inverter 48a and 48b to the hoist 20a and 20b, so that the hanging basket device 5 is raised and lowered.

[0047] However, the drive device 40 is large in size and heavy in weight. If such a drive device 40 is mounted in the car 10 (in the working area), the working area in the car 10 is compressed. If the drive device 40 is installed on the outer side of the car 10, not only the front-to-back direction and / or left-to-right direction of the car 10 needs to be compressed, but also the access to the working object (e.g., the equipment on the wall of the hoistway 1) from the car 10 in the horizontal direction is restricted, and the operation may become difficult.

[0048] In order to solve such a problem, the hanging basket device 5 of the present embodiment has an underfloor shelf 50. The underfloor shelf 50 is arranged below the car 10. At least a portion of the driving device 40 is supported by the underfloor shelf 50. More specifically, the underfloor shelf 50 forms a space between the underfloor shelf 50 and the car 10, and at least a portion of the driving device 40 is arranged in the space. At least a portion of the driving device 40 is supported from below by the underfloor shelf 50. As a result, the area occupied by the driving device 40 in the car 10 can be compressed. Therefore, the working area can be expanded. In addition, by arranging at least a portion of the driving device 40 below the car 10, it is possible to suppress the situation where access to the working object from the car 10 in the horizontal direction is restricted by the driving device 40. The volume of at least a portion of the driving device 40 arranged on the underfloor shelf 50 is preferably more than one-half of the total volume of the driving device 40, more preferably more than two-thirds, and further preferably more than three-quarters. In addition, the weight of at least a portion of the driving device 40 disposed on the underfloor shelf 50 is preferably more than one-half of the total weight of the driving device 40, more preferably more than two-thirds, and further preferably more than three-quarters. In the illustrated example, the battery cabinet 41 and the inverter cabinet 45, which are large in size and weight, are disposed on the underfloor shelf 50. The operating cabinet 47, which is small in size and weight, is disposed in the car 10. As a result, the area occupied by the driving device 40 in the car 10 can be effectively compressed. In addition, the situation in which access to the work object from the car 10 in the horizontal direction is restricted by the driving device 40 can be effectively suppressed. In addition, as described later, the position of the center of gravity of the hanging basket device 5 in the horizontal direction can be effectively adjusted.

[0049] The underfloor shelf 50 includes a shelf body 51 and a pair of connecting plates 56a, 56b. The shelf body 51 is connected to the car 10 via the connecting plates 56a, 56b. The shelf body 51 includes a bottom plate 52, a pair of transverse plates 53a, 53b and a front plate 54. The bottom plate 52 is arranged in a manner separated from the floor portion 12 in the vertical direction. A space is formed between the bottom plate 52 and the floor portion 12 of the car 10. The bottom plate 52 is connected to the car 10 via a pair of transverse plates 53a, 53b and a pair of connecting plates 56a, 56b. When viewed from the vertical direction, the bottom plate 52 is arranged in an area surrounded by the edges 12a to 12d of the floor portion 12. Thereby, the possibility of interference between the underfloor shelf 50 and the equipment in the hoistway 1 when the hanging basket device 5 is raised or lowered can be suppressed. The bottom plate 52 supports at least a part of the drive device 40 (in the example shown in the figure, the battery cabinet 41 and the inverter cabinet 45) from below.

[0050] like Figure 6As shown, the bottom plate 52 is a quadrilateral in shape as a whole and has edges 52a to 52d. The edges 52a and 52b extend in the front-to-back direction. The edges 52a and 52b are the right edge and the left edge of the bottom plate 52, respectively. The edges 52c and 52d extend in the left-right direction. The edges 52c and 52d are the rear edge and the front edge of the bottom plate 52, respectively.

[0051] The front plate 54 is assembled to the front side edge 52d of the bottom plate 52. Figure 5 As shown, the front plate 54 extends to a position above the bottom plate 52. Thus, the possibility of the battery cabinet 41 and the inverter cabinet 45 arranged on the bottom plate 52 sliding forward from the underfloor shelf 50 can be prevented.

[0052] The front plate 54 is detachably assembled to the front side edge 52d of the bottom plate 52. Therefore, by removing the front plate 54 from the bottom plate 52, when the battery cabinet 41 and the inverter cabinet 45 are arranged on the bottom plate 52 or removed from the bottom plate 52, the front plate 54 can be prevented from interfering with the battery cabinet 41 and the inverter cabinet 45. Therefore, it is easy to place the battery cabinet 41 and the inverter cabinet 45 on the bottom plate 52. In the example shown in the figure, the front plate 54 is fixed to the bottom plate 52 by fasteners such as bolts.

[0053] In addition, the sum of the left-right dimensions of the battery cabinet 41 and the inverter cabinet 45 is preferably smaller than the left-right dimension of the elevator entrance 4. This prevents interference between the wall 1a of the hoistway 1 and the battery cabinet 41 and the inverter cabinet 45. Therefore, it is easy to place the battery cabinet 41 and the inverter cabinet 45 on the bottom plate 52 from the elevator hall.

[0054] exist Figure 5 In the example shown, a rear wall 55 is connected to the rear side edge 52c of the bottom plate 52. The rear wall 55 extends to a position above the bottom plate 52. This prevents the battery cabinet 41 and the inverter cabinet 45 arranged on the bottom plate 52 from sliding backward from the underfloor shelf 50. The rear wall 55 can be formed integrally with the bottom plate 52. The bottom plate 52 and the rear wall 55 can be formed integrally by, for example, bending the rear end of a metal plate upward. The front plate 54 and the rear wall 55 are opposite to each other in the front-to-back direction.

[0055] like Figure 4 and Figure 6As shown, a pair of transverse plates 53a, 53b are opposite to each other in the left-right direction. The transverse plates 53a, 53b extend to a position above the bottom plate 52. The lower end of the right transverse plate 53a is connected to the right edge 52a of the bottom plate 52. The lower end of the left transverse plate 53b is connected to the left edge 52b of the bottom plate 52. The upper ends of the pair of transverse plates 53a, 53b are fixed to a pair of connecting plates 56a, 56b. In the example shown in the figure, the transverse plates 53a, 53b are fixed to the connecting plates 56a, 56b in a detachable manner. In the example shown in the figure, the pair of transverse plates 53a, 53b are fixed to the connecting plates 56a, 56b using bolts Ba, Bb and nuts Na, Nb. Bolt holes h for inserting bolts Ba, Bb are formed at the upper ends of each of the transverse plates 53a, 53b. As shown in FIG. Figure 6 As shown, the battery cabinet 41 and the inverter cabinet 45 are arranged in a region surrounded by a front plate 54, a rear wall 55, and a pair of horizontal plates 53a, 53b.

[0056] A pair of connecting plates 56a, 56b are fixed to the lower surface of the floor portion 12 of the car 10. The pair of connecting plates 56a, 56b extend in the front-rear direction. The pair of connecting plates 56a, 56b are opposite to each other in the left-right direction. The right transverse plate 53a is connected to the right connecting plate 56a, and the left transverse plate 53b is connected to the left connecting plate 56b.

[0057] Bolt holes h for inserting bolts Ba and Bb are formed on the connecting plates 56a and 56b. In the example shown in the figure, a plurality of bolt holes ha to hj arranged in the front-to-back direction are formed on the connecting plates 56a and 56b. As a result, the fixing positions of the transverse plates 53a and 53b (and therefore the shelf body 51) relative to the connecting plates 56a and 56b can be changed in the front-to-back direction. By changing the fixing positions of the transverse plates 53a and 53b relative to the connecting plates 56a and 56b in the front-to-back direction, the positions of the battery cabinet 41 and the inverter cabinet 45 in the hanging basket device 5 can be greatly changed in the front-to-back direction. Therefore, the position of the center of gravity of the hanging basket device 5 can be greatly changed in the front-to-back direction. In the example shown in the figure, as Figure 2A to Figure 2CAs shown, the floor portion 12 of the car 10 can be extended rearward. If the floor portion 12 is extended rearward, the center of gravity of the floor portion 12 moves rearward significantly. In this case, by changing the fixed position of the shelf body 51 relative to the connecting plates 56a, 56b forward, the position of the center of gravity of the hanging basket device 5 can be suppressed from moving rearward. Thus, even if the fixed position of the hoist 20a, 20b on the floor portion 12 remains unchanged, the hanging basket device 5 can be suppressed from tilting rearward. Therefore, the operation can be performed safely. Alternatively, the load applied from the hanging basket device 5 to the above-mentioned guide rail due to the position of the center of gravity of the hanging basket device 5 moving rearward, and the load applied from the guide rail to the hanging basket device 5 due to its reaction can be suppressed from increasing. As a result, the strength required for the guide rail, the hanging basket device 5 (especially the car 10) can be reduced. By reducing the strength required for the car 10, the weight of the car 10 can be reduced.

[0058] like Figure 7 As shown, the connecting plates 56a and 56b may be provided with marks Ma to Mc indicating the fixing positions of the shelf body 51 (horizontal plates 53a and 53b) corresponding to the dimensions of the floor portion 12 in the front-rear direction. Figure 7 In the example shown, when the floor portion 12 is formed only of the floor 13a, the front-rear balance of the hanging basket device 5 is improved by inserting the bolts Ba and Bb into the bolt holes ha and hd indicated by the symbol Ma. Figure 7 In the example shown, when the floor portion 12 is formed of the floor 13a and the additional floor 13b, the front-rear balance of the hanging basket device 5 is improved by inserting the bolts Ba and Bb into the bolt holes hb and hf indicated by the reference numeral Mb. Figure 7 In the example shown, it is shown that when the floor portion 12 is formed by the floor 13a and the additional floors 13b and 13c, the balance of the hanging basket device 5 in the front-to-back direction becomes good by inserting the bolts Ba and Bb into the bolt holes hg and hj indicated by the mark Mc. The marks Ma to Mc can be formed, for example, by engraving, painting or stickers. Of course, the fixing position of the shelf body 51 relative to the connecting plates 56a and 56b is arbitrary. Therefore, the bolts Ba and Bb for fixing the shelf body 51 can also be inserted into the bolt holes hc, he, hh, hi other than the bolt holes ha, hb, hd, hf, hg, hj indicated by the marks Ma to Mc.

[0059] Moreover, in Figure 6 In the example shown, the dimension of the bottom plate 52 in the front-to-back direction (in other words, the distance between the front plate 54 and the rear wall 55) is larger than the dimension of the battery cabinet 41 and the inverter cabinet 45 in the front-to-back direction. Thus, the position of the center of gravity of the hanging basket device 5 can be adjusted in the front-to-back direction by adjusting the position of the battery cabinet 41 and the inverter cabinet 45 on the underfloor shelf 50 in the front-to-back direction. Figure 6 In the example shown, the left-right dimension of the bottom plate 52 (in other words, the distance between a pair of horizontal plates 53a and 53b) is larger than the left-right dimension of the battery cabinet 41 and the inverter cabinet 45. As a result, the position of the battery cabinet 41 and the inverter cabinet 45 on the underfloor shelf 50 can be adjusted in the left-right direction to adjust the left-right position of the center of gravity of the hanging basket device 5. This can also suppress the inclination of the hanging basket device 5, and operations can be performed safely. In addition, the strength required for the guide rails and the hanging basket device 5 (especially the car 10) can be reduced. Since the weights of the battery cabinet 41 and the inverter cabinet 45 are different from each other, the left-right position adjustment of the center of gravity of the hanging basket device 5 can also be performed by swapping the left-right positions of the battery cabinet 41 and the inverter cabinet 45.

[0060] In the example shown in the figure, the battery cabinet 41 and the inverter cabinet 45, which are heavier than the battery cabinet 41, the inverter cabinet 45, and the operation cabinet 47 that constitute the driving device 40, are arranged on the underfloor shelf 50. Therefore, the position of the center of gravity of the hanging basket device 5 can be effectively adjusted by moving the underfloor shelf 50 or by adjusting the position of the driving device 40 on the underfloor shelf 50.

[0061] As described above, the guide rails for stabilizing the posture of the hanging basket device 5 do not exist in the shaft 1 in the initial stage of the operation using the hanging basket device 5. According to this embodiment, by moving the underfloor shelf 50 or by adjusting the positions of the battery cabinet 41 and the inverter cabinet 45 on the underfloor shelf 50, the hanging basket device 5 can maintain a certain degree of posture for lifting and lowering even without the guide rails.

[0062] In addition, various changes can be added to the above-mentioned one embodiment.

[0063] For example, Figure 8As shown, the bolt hole h formed in the connecting plates 56a and 56b can be a so-called gourd hole. In this case, the bolt hole has a large diameter hole h1 and a small diameter hole h2. The small diameter hole h2 is connected to the large diameter hole h1 from below. The small diameter hole h2 is connected to the large diameter hole h1. The radius of the inscribed circle of the small diameter hole h2 is smaller than the radius of the inscribed circle of the large diameter hole h1. However, both the large diameter hole h1 and the small diameter hole h2 have a size that can be inserted into the rod of the bolt Ba and Bb. The rod of the bolt Ba and Bb can move from the large diameter hole h1 to the small diameter hole h2 in the up and down direction. The small diameter hole h2 is formed at an appropriate position as a fastening position of the bolt Ba and Bb. By making the bolt hole h a gourd hole, it is easy to insert the bolt Ba and Bb into the bolt hole h. That is, by inserting the bolt Ba and Bb into the large diameter hole h1, the bolt Ba and Bb can be easily inserted into the bolt hole h. In addition, even if the bolts Ba and Bb are inserted into the large-diameter holes h1, the bolts Ba and Bb will move into the small-diameter holes h2 due to gravity, so the bolts Ba and Bb can be automatically arranged at appropriate positions in the bolt holes h. Therefore, by simply inserting the bolts Ba and Bb assembled on the shelf body 51 (more specifically, the horizontal plates 53a and 53b) into the bolt holes h, the shelf body 51 can be automatically arranged at an appropriate position relative to the connecting plates 56a and 56b by gravity. In addition, if the nuts Na and Nb are screwed on the bolts Ba and Bb arranged in the small-diameter holes, the shelf body 51 can be properly fastened to the connecting plates 56a and 56b. Therefore, the operation of installing the shelf body 51 on the connecting plates 56a and 56b can be simplified. That is, it is not necessary to screw the nuts Na and Nb on the bolts Ba and Bb while supporting the shelf body 51 by hand to adjust its position relative to the connecting plates 56a and 56b.

[0064] In one embodiment and its modified example described above, the hanging basket device 5 includes a car 10, hoists 20a, 20b, a drive device 40 and an underfloor shelf 50. The hoists 20a, 20b are fixed to the car 10 and wind the wire ropes 2a, 2b that suspend the car 10. The drive device 40 includes a rechargeable battery 42 and drives the hoists 20a, 20b. The underfloor shelf 50 is arranged below the car 10 and supports at least a portion of the drive device 40. As a result, the area occupied by the drive device 40 in the car 10 can be compressed. Therefore, the working area can be expanded. In addition, by arranging at least a portion of the drive device 40 below the car 10, it is possible to suppress the situation where access to the working object from the car 10 in the horizontal direction is restricted by the drive device 40.

[0065] In the above-described embodiment and its modified example, the weight of at least a portion of the driving device 40 disposed on the underfloor shelf 50 is at least half of the total weight of the driving device 40. Thus, the position of the center of gravity of the hanging basket device 5 in the horizontal direction can be effectively adjusted.

[0066] In addition, in one embodiment and its modified example described above, the driving device 40 includes a battery cabinet 41, an inverter cabinet 45 and an operating cabinet 47. The battery cabinet 41 includes a rechargeable battery 42. The inverter cabinet 45 converts the power output from the rechargeable battery 42 into alternating current. The operating cabinet 47 converts the power output from the inverter cabinet 45 into power suitable for driving the hoists 20a, 20b. The battery cabinet 41 and the inverter cabinet 45 are arranged on the underfloor shelf 50. By arranging the battery cabinet 41 and the inverter cabinet 45, which are large in size and weight among the battery cabinet 41, the inverter cabinet 45 and the operating cabinet 47 constituting the driving device 40, on the underfloor shelf 50, the area occupied by the driving device 40 in the car 10 can be effectively compressed. In addition, the position of the center of gravity of the hanging basket device 5 in the horizontal direction can be effectively adjusted.

[0067] In addition, in the above-described embodiment and its modified example, the underfloor shelf 50 includes a shelf body 51. At least a portion of the drive device 40 is disposed on the shelf body 51. The position of the shelf body 51 relative to the car 10 can be changed in the front-to-back direction. In addition, the position of the center of gravity of the hanging basket device 5 in the front-to-back direction can be effectively adjusted.

[0068] In addition, in one embodiment and its modified example described above, the underfloor shelf 50 includes connecting plates 56a and 56b. The connecting plates 56a and 56b are fixed to the car 10. The shelf body 51 is fixed to the connecting plates 56a and 56b by bolts Ba and Bb. The connecting plates 56a and 56b include a plurality of bolt holes ha to hj arranged in the front-to-back direction. By changing the bolt holes ha to hj for the bolts Ba and Bb to be inserted, the fixed position of the shelf body 51 relative to the car 10 can be changed in the front-to-back direction. In this case, it is easy to adjust the position of the center of gravity of the hanging basket device 5 in the front-to-back direction.

[0069] In addition, in the above-described embodiment and its modified example, the dimension of the floor portion 12 of the car 10 in the front-to-back direction can be changed. The underfloor shelf 50 includes connecting plates 56a and 56b. The connecting plates 56a and 56b are fixed to the car 10. The fixing position of the shelf body 51 corresponding to the dimension of the floor portion 12 in the front-to-back direction is shown on the connecting plates 56a and 56b. In this case, it is easy to appropriately adjust the position of the center of gravity of the hanging basket device 5 in the front-to-back direction.

[0070] In addition, in the above-described embodiment and its modified example, the underfloor shelf 50 includes connecting plates 56a, 56b. The connecting plates 56a, 56b are fixed to the car 10. The shelf body 51 is fixed to the connecting plates 56a, 56b by bolts Ba, Bb. The connecting plates 56a, 56b include bolt holes h. The bolt holes h include large-diameter holes h1 and small-diameter holes h2. The small-diameter holes h2 are connected to the large-diameter holes h1 from below. In this case, the shelf body 51 can be easily mounted on the connecting plates 56a, 56b.

[0071] In addition, in one embodiment and its modified example described above, the underfloor shelf 50 includes a bottom plate 52 and a front plate 54. The bottom plate 52 supports at least a portion of the drive device 40 from below. The front plate 54 is connected to the front edge 52d of the bottom plate 52 and extends to a position above the upper surface of the bottom plate 52. The front plate 54 is connected to the front edge 52d of the bottom plate 52 in a detachable manner. Thus, the possibility of at least a portion of the drive device 40 arranged on the bottom plate 52 sliding forward from the underfloor shelf 50 can be prevented. In addition, if the front plate 54 is removed from the bottom plate 52, when at least a portion of the drive device 40 is arranged on the bottom plate 52 or removed from the bottom plate 52, the front plate 54 can be prevented from interfering with at least a portion of the drive device 40. Therefore, it is easy to place at least a portion of the drive device 40 on the bottom plate 52.

[0072] In addition, in the above-described embodiment and its modified example, the underfloor shelf 50 includes a bottom plate 52 and a rear wall 55. The bottom plate 52 supports at least a portion of the drive device 40 from below. The rear wall 55 is connected to the rear edge 52c of the bottom plate 52 and extends to a position above the upper surface of the bottom plate 52. Thus, the possibility of at least a portion of the drive device 40 disposed on the bottom plate 52 sliding backward from the underfloor shelf 50 can be prevented.

[0073] In addition, in the above-described embodiment and its modified example, the underfloor shelf 50 includes a bottom plate 52. The bottom plate 52 supports at least a portion of the drive device 40 from below. The dimension of the bottom plate 52 in the front-to-back direction is larger than the dimension of at least a portion of the drive device 40 in the front-to-back direction. In this case, by adjusting the position of at least a portion of the drive device 40 on the bottom plate 52 in the front-to-back direction, the position of the center of gravity of the hanging basket device 5 in the front-to-back direction can be adjusted.

[0074] In addition, in the above-described embodiment and its modified example, the underfloor shelf 50 includes a bottom plate 52. The bottom plate 52 supports at least a portion of the drive device 40 from below. The left-right dimension of the bottom plate 52 is larger than the left-right dimension of at least a portion of the drive device 40. In this case, by adjusting the position of at least a portion of the drive device 40 on the bottom plate 52 in the left-right direction, the position of the center of gravity of the hanging basket device 5 in the left-right direction can be adjusted.
