[0007] Patent Document 1: Japanese Patent Application Publication No. 2001-114485 Summary of the Invention

[0008] The technical problem that the invention aims to solve

[0009] However, when fitting the lower frame, which is integrated with the car floor, into the longitudinal frames, the lower frame is obscured by the car floor when viewed from above, making it impossible to visually identify the fitting point between the lower frame and the longitudinal frames. As a result, adjusting the position of the lower frame relative to the left and right longitudinal frames becomes difficult, complicating the installation process. Furthermore, visually identifying the fitting point requires workers to enter the pit and observe from below, hindering safety improvements.

[0010] The purpose of this invention is to provide a car and elevator that can be easily installed, taking into account the aforementioned problems.

[0011] Technical means for solving technical problems

[0012] To solve the aforementioned problems and achieve the objective of the invention, the elevator car includes: a car frame having a pair of longitudinal frames and a lower frame connecting the lower ends of the pair of longitudinal frames; and a car compartment having a car floor integrally assembled with the lower frame. Furthermore, the pair of longitudinal frames have fitting portions for fitting the lower frame and guide portions for guiding the lower frame to the fitting portions. In addition, the elevator includes the aforementioned car for moving up and down within a shaft.

[0024] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In this specification and drawings, elements having substantially the same function or structure are labeled with the same reference numerals, and repeated descriptions are omitted.

[0025] 1. Implementation Method 1

[0026] [elevator]

[0027] First, refer to Figure 1 The structure of the elevator according to Embodiment 1 of the present invention will be described. Figure 1This is a simplified structural diagram of the elevator involved in Implementation Method 1.

[0028] like Figure 1 As shown, the elevator includes a traction machine 1, a main rope 2, a car 3, a counterweight 5, and pulleys 6. The car 3 includes a pair of car pulleys 4A and 4B. The car 3 moves up and down in the hoistway 100 according to the movement of the main rope 2 wound on the pair of car pulleys 4A and 4B.

[0029] The traction machine 1 is a device that winds up the main rope 2 to raise and lower the car 3. The traction machine 1 is located at the top of the hoistway 100. One end and the other end of the main rope 2 are fixed to the top of the hoistway 100. The main rope 2 is wound around a pair of car pulleys 4A and 4B, the traction machine 1, and pulley 6.

[0030] The car 3 is guided and raised / lowered by a pair of guide rails (not shown). A pair of car pulleys 4A and 4B are located on the underside of the car 3. The counterweight 5 is used to achieve mass balance with the car 3, thereby reducing the load on the traction machine 1. When the traction machine 1 winds up the main rope 2, the counterweight 5 rises and falls in the opposite direction to the car 3. Pulleys 6 are located on top of the counterweight 5 and rise and fall integrally with the counterweight 5.

[0031] [Elevator Car]

[0032] Next, refer to Figure 2 Explain the structure of car 3. Figure 2 This is a three-dimensional view showing the exterior of car 3.

[0033] In this embodiment, the front-back, up-down, and left-right directions are defined based on the elevator user's line of sight relative to the car 3. In this case, from the elevator user's perspective, the front side is the forward direction, the inside side is the rear direction, the top side is the upper direction, the bottom side is the lower direction, the left side is the left direction, and the right side is the right direction.

[0034] like Figure 2 As shown, the car 3 includes a car frame 7 and a car compartment 8 disposed inside the car frame 7. The car compartment 8 has internal space for loading goods and passengers. The car compartment 8 is formed by a car floor 12, side panels 13, and a car roof 15. The car floor 12 and car roof 15 are arranged opposite each other in the vertical direction via the aforementioned space. The side panels 13 are arranged to surround the aforementioned space on all four sides except for the portion of the car door 18.

[0035] Viewed from the front and rear, the car frame 7 is a long rectangle. The car frame 7 is configured to surround the car compartment 8. The car frame 7 has an upper frame 9 disposed above the car compartment 8 and a lower frame 10 disposed below the car compartment 8 (see reference). Figure 5 ), and a pair of longitudinal frames 11A and 11B arranged on the left and right sides of the car compartment 8.

[0036] The upper frame 9 is a relatively long component extending in the left-right direction. The upper frame 9 is horizontally mounted between the upper ends of a pair of longitudinal frames 11A and 11B. One end of the upper frame 9 in the long side direction is fixed to the upper end of the longitudinal frame 11A, and the other end of the upper frame 9 in the long side direction is fixed to the upper end of the longitudinal frame 11B. Thus, the upper ends of the pair of longitudinal frames 11A and 11B are connected by the upper frame 9.

[0037] A pair of longitudinal frames 11A and 11B are configured to face each other in the left-right direction. Each longitudinal frame 11A and 11B is a relatively long member extending in the vertical direction. Each longitudinal frame 11A and 11B is movably supported by the aforementioned pair of guide rails. The guide rails are slender members that are vertically mounted on the wall of the shaft 100.

[0038] The lower frame 10 is positioned opposite the upper frame 9 via the car compartment 8. The lower frame 10 is a generally rectangular parallelepiped-shaped component that extends relatively long in the left-right direction (see reference). Figure 5 The corners formed by the lower surface and side surfaces of the lower frame 10 are rounded.

[0039] The lower frame 10 is horizontally mounted between the lower ends of a pair of longitudinal frames 11A and 11B. One end of the lower frame 10 along its long side is fixed to the lower end of the longitudinal frame 11A, and the other end of the lower frame 10 along its long side is fixed to the lower end of the longitudinal frame 11B. Thus, the lower ends of the pair of longitudinal frames 11A and 11B are connected by the lower frame 10.

[0040] The lower frame 10 supports the car floor 12 via a pair of car floor support beams 14A and 14B. The pair of car floor support beams 14A and 14B are beams that support the car floor 12. Vibration damping sections 20 are respectively provided at both ends of the long side of the car floor support beams 14A and 14B. The vibration damping sections 20 are components that suppress vibrations in the car chamber 8, including the car floor 12. The car floor 12 is supported by the pair of car floor support beams 14A and 14B via multiple (four in this embodiment) vibration damping sections 20.

[0041] Car bottom support beam 14A is disposed on one end (right end) of the long side of the lower frame 10. Car bottom support beam 14B is disposed on the other end (left end) of the long side of the lower frame 10. Furthermore, each car bottom support beam 14A and 14B, when placed on the lower frame 10, is fixed to the upper surface of the lower frame 10 by bolts (not shown). Each car bottom support beam 14A and 14B is horizontally arranged in a direction perpendicular to the lower frame 10. Specifically, the lower frame 10 is arranged parallel to the left-right direction, and each car bottom support beam 14A and 14B is arranged parallel to the front-back direction.

[0042] The car door 18 is located at the front of the car compartment 8. The car door 18 is configured to open and close in the left and right directions. A pair of car pulleys 4A and 4B are located on the lower side of the car compartment 8 (4B refers to...). Figure 1 The car lower rollers 4A and 4B are configured on the front side of the longitudinal frames 11A and 11B. One car lower roller 4A is installed on the car bottom support beam 14A, and the other car lower roller 4B is installed on the car bottom support beam 14B.

[0043] [A pair of vertical frames]

[0044] Next, refer to Figure 3 Describe the structure of a pair of longitudinal frames 11A and 11B. Figure 3 It is a three-dimensional view of a pair of vertical frames 11A and 11B.

[0045] like Figure 3 As shown, the longitudinal frame 11A has a longitudinal frame body 21, connecting members 22, and fitting parts 23. The longitudinal frame body 21 extends relatively long in the vertical direction. The longitudinal frame body 21 has two opposing side portions 21A and 21B in the front-rear direction, and a main body plate 21C continuous with the two side portions 21A and 21B. The main body plate 21C is opposite to the car compartment 8. The two side portions 21A and 21B protrude substantially vertically from both ends of the main body plate 21C toward the side opposite to the car compartment 8.

[0046] Connecting member 22 is located directly above the car lower pulley 4A, connecting the longitudinal frame 11A and the car bottom support beam 14A (see reference). Figure 2 Similar to the longitudinal frame body 21, the connecting member 22 is composed of a curved member with a generally U-shaped cross-section parallel to the horizontal direction. The connecting member 22 has a first plate portion arranged parallel to the main plate 21C of the longitudinal frame body 21, and a second plate portion and a third plate portion continuous with the first plate portion.

[0047] The second and third plates of the connecting member 22 are opposite each other in the front-rear direction. The second plate of the connecting member 22 is fixed to the side 21A of the longitudinal frame body 21 using bolts (screws). In addition, the third plate of the connecting member 22 is fixed to the car bottom support beam 14A via an intermediate member (not shown).

[0048] The fitting part 23 is fixed to the lower part of the longitudinal frame body 21. The fitting part 23 is disposed on the surface of the longitudinal frame 11A opposite to the longitudinal frame 11B. Lower frame 10 (see reference) Figure 5 One end of the long side of the ) is fitted into the fitting part 23 from above.

[0049] The fitting part 23 is an integral structure obtained by bending a metal plate. The fitting part 23 has a pair of wall panels 23A and 23B facing each other in the front-rear direction, and a base plate 23C with a plane that is substantially perpendicular in the vertical direction. The pair of wall panels 23A and 23B are formed in a generally rectangular shape, with the two long sides forming the upper and lower ends. The pair of wall panels 23A and 23B are fixed to the two sides 21A and 21B of the longitudinal frame 11A using bolts (screws).

[0050] The base plate 23C is roughly rectangular. Two opposite sides of the base plate 23C in the front-to-back direction are continuous with the lower ends of a pair of wall panels 23A and 23B. Lower frame 10 (see reference) Figure 5 One end of the long side is fixed to the base plate 23C with bolts (screws).

[0051] Conical pieces 24A and 24B are respectively disposed at the upper ends of a pair of wall plates 23A and 23B. The conical pieces 24A and 24B illustrate a specific example of the guide portion according to the present invention. The conical pieces 24A and 24B protrude obliquely from the upper ends of the pair of wall plates 23A and 23B. The conical pieces 24A and 24B are formed from a plate body continuous with the pair of wall plates 23A and 23B.

[0052] The conical plates 24A and 24B are tilted so that they are separated from each other as their front ends face opposite sides of the pair of wall panels 23A and 23B. The upward-facing inclined surface (hereinafter referred to as the "guide surface") of the conical plates 24A and 24B guides one end of the lower frame 10 along its long side to the fitting portion 23. At this time, the corner formed by the lower surface and side surface of the lower frame 10 slides on the guide surface of the conical plates 24A and 24B. Additionally, friction-reducing materials such as grease or lubricating oil can be applied to the guide surface of the conical plates 24A and 24B.

[0053] The longitudinal frame 11B has a longitudinal frame body 25, a connecting member 26, and a fitting portion 27. The longitudinal frame body 25 has the same structure as the longitudinal frame body 21 of the longitudinal frame 11A described above, having two side portions 25A and 25B and a main body plate 25C continuous with the two side portions 25A and 25B. The connecting member 26 has the same structure as the connecting member 22 of the longitudinal frame 11A described above. The connecting member 26 is located directly above the car lower pulley 4B and connects the longitudinal frame 11B and the car bottom support beam 14B (see reference). Figure 5 ).

[0054] The fitting part 27 has the same structure as the fitting part 23 of the longitudinal frame 11A described above, and is fixed to the lower part of the longitudinal frame body 25. The fitting part 27 is disposed on the longitudinal frame 11A side of the longitudinal frame 11B. Lower frame 10 (refer to...) Figure 5The other end of the long side of the plate 23 is fitted into the fitting portion 27 from above. The fitting portion 23 has a pair of wall plates 27A and 27B and a bottom plate 27C.

[0055] Conical pieces 28A and 28B are respectively disposed at the upper ends of a pair of wall plates 27A and 27B. Conical pieces 28A and 28B, together with the aforementioned conical pieces 24A and 24B, illustrate a specific example of the guide portion according to the present invention. Conical pieces 28A and 28B protrude obliquely from the upper ends of the pair of wall plates 27A and 27B. Conical pieces 28A and 28B are formed from a plate body continuous with the pair of wall plates 27A and 27B.

[0056] The conical plates 28A and 28B are tilted so that they are separated from each other as their front ends face opposite sides of the pair of wall panels 27A and 27B. The upward-facing inclined surface (hereinafter referred to as the "guide surface") of the conical plates 28A and 28B guides the other end of the lower frame 10 along its long side to the fitting portion 27. At this time, the corner formed by the lower surface and side surface of the lower frame 10 slides on the guide surface of the conical plates 28A and 28B. Additionally, friction-reducing materials such as grease or lubricating oil can be applied to the guide surface of the conical plates 28A and 28B.

[0057] [Elevator car installation work]

[0058] Next, the installation of car 3 will be explained. Figure 4 This is an explanatory diagram showing the car lower assembly according to Embodiment 1 installed on a pair of longitudinal frames from above. Figure 5 This is an illustrative diagram showing the lower part of the car assembly being installed on a pair of longitudinal frames from below. Figure 6 It is along Figure 4 The cross-sectional view shown along line AA.

[0059] like Figure 4 and Figure 5 As shown, the lower frame 10 of the car 3, a pair of car bottom support beams 14A and 14B, and the car bottom 12 are assembled as a single unit and transported to the installation site as the lower assembly 30 of the car. When installing the car 3, the pair of longitudinal frames 11A and 11B are first installed on guide rails (not shown). At this time, the pair of longitudinal frames 11A and 11B are fixed to the guide rails. Then, after assembling the car 3, the car frame 7 can be moved relative to the guide rails.

[0060] Next, the lower car assembly 30 is positioned above the mating portions 23 and 27 of the pair of longitudinal frames 11A and 11B. For example... Figure 4 As shown, a mark 31 for aligning with the positions of a pair of longitudinal frames 11A, 11B is formed on the upper surface of the car bottom 12 in the lower assembly 30. The mark 31 is provided on two opposite sides in the left-right direction of the car bottom 12.

[0061] Mark 31 consists of two lines spaced a predetermined distance apart in the front-to-back direction and extending in the left-to-right direction. The distance between the two lines is equal to the front-to-back length of the pair of longitudinal frames 11A and 11B. The operator observes the lower assembly 30 from above and aligns the two lines of mark 31 with the two ends of the pair of longitudinal frames 11A and 11B in the front-to-back direction. Thus, as... Figure 6 As shown, the lower frame 10 can be easily aligned with the front and rear positions of the fitting parts 23 and 27.

[0062] Next, the lower car assembly 30 is lowered, causing the two ends of the lower frame 10 along its long side to engage with the fitting portions 23 and 27 of a pair of longitudinal frames 11A and 11B. At this time, if the position of the lower frame 10 in the front-rear direction is slightly offset relative to the fitting portions 23 and 27, the corners formed by the lower surface and side surfaces of the lower frame 10 contact the tapered plates 24A, 24B, 28A, and 28B of the pair of longitudinal frames 11A and 11B. Then, the two ends of the lower frame 10 along its long side are guided to the fitting portions 23 and 27 via the tapered plates 24A, 24B, 28A, and 28B. As a result, the lower frame 10 can be easily engaged with the fitting portions 23 and 27.

[0063] Figure 7 This is an explanatory diagram showing the lower car assembly 30 mounted on a pair of longitudinal frames 11A and 11B, viewed from above. Figure 8 It is along Figure 7 The sectional view shown is along the BB line.

[0064] like Figure 7 and Figure 8 As shown, after the lower frame 10 is fitted with the fitting parts 23 and 27, the two ends of the lower frame 10 along its long side are fixed to the base plates 23C and 27C of the fitting parts 23 and 27 using bolts (screws). Next, a pair of car bottom support beams 14A and 14B of the lower car assembly 30 are fixed to the connecting members 22 and 26 of a pair of longitudinal frames 11A and 11B via intermediate members. Thus, the lower car assembly 30 is installed onto the pair of longitudinal frames 11A and 11B.

[0065] Next, the four side panels 13 are fixed to the car floor 12, and the car roof 15 is fixed to the four side panels 13. Thus, the car compartment 8 is assembled (see reference). Figure 2 Next, bolts (screws) are used to fix the two ends of the long side of the upper frame 9 to the upper ends of the longitudinal frames 11A and 11B. Thus, the car frame 7 is assembled, and the installation of the car 3 is complete.

[0066] 2. Implementation Method 2

[0067] Next, the elevator according to Embodiment 2 of the present invention will be described. The elevator according to Embodiment 2 has the same structure as the elevator according to Embodiment 1 described above. The only difference between the elevator according to Embodiment 2 and the elevator according to Embodiment 1 is the car frame 7A. Therefore, the car frame 7A will be described here, and the description of the structure common to Embodiment 1 will be omitted.

[0068] [Car frame]

[0069] Figure 9 This is a cross-sectional view showing the fitted state of the lower frame and a pair of longitudinal frames according to Embodiment 2. Figure 9 As shown, the car frame 7A according to Embodiment 2 has a lower frame 40 disposed at the lower part of the car compartment 8, and a pair of longitudinal frames 41A and 41B disposed on the left and right sides of the car compartment 8. Figure 9 The longitudinal frame 7A is shown, as well as the upper frame 9 (not shown) disposed on the upper part of the car compartment 8. The upper frame 9 is the same as in Embodiment 1. When viewed from the front-rear direction, the car frame 7A is formed as a rectangle with a longer longitudinal direction.

[0070] The lower frame 40 is a roughly rectangular parallelepiped extending relatively long in the left-right direction. The lower frame 40 is horizontally mounted between the lower ends of a pair of longitudinal frames 41A and 41B. One end of the lower frame 40 along its long side is fixed to the lower end of the longitudinal frame 41A, and the other end of the lower frame 40 along its long side is fixed to the lower end of the longitudinal frame 41B. Thus, the lower ends of the pair of longitudinal frames 41A and 41B are connected via the lower frame 40. Furthermore, the lower frame 40 supports the car floor 12 via a pair of car floor support beams 14A and 14B. Figure 9 (Not shown in the figure).

[0071] The longitudinal frame 41A has a longitudinal frame body 51, a connecting member 22 (not shown) identical to that in Embodiment 1, and a fitting portion 53. The longitudinal frame body 51 extends relatively long in the vertical direction. The longitudinal frame body 51 has two opposing sides 51A and 51B in the front-rear direction, and a main body plate 51C continuous with the two sides 51A and 51B. The main body plate 51C is opposite to the car compartment 8. The two sides 51A and 51B protrude substantially vertically from both ends of the main body plate 51C toward the side opposite to the car compartment 8. The connecting member 22 (not shown) connects the longitudinal frame 41A and the car bottom support beam 14A.

[0072] The fitting part 53 is fixed to the lower part of the longitudinal frame body 51. The fitting part 53 is disposed on the surface of the longitudinal frame 41A opposite to the longitudinal frame 41B. One end of the lower frame 40 in the long side direction fits into the fitting part 53 from above. The fitting part 53 has the same structure as the fitting part 23 according to Embodiment 1, and has a pair of wall panels 53A, 53B and a bottom plate 53C.

[0073] A guide pin 54 extending vertically is mounted to the upper surface of the base plate 53C. The guide pin 54 illustrates another specific example of a guide portion according to the present invention. The guide pin 54 tapers towards the front end. The front end of the guide pin 54 protrudes upwards beyond the fitting portion 53. The guide pin 54 guides one end of the lower frame 40 along its long side to the fitting portion 53.

[0074] like Figure 9 As shown, a pin insertion hole 40a for inserting a guide pin 54 is formed on the lower surface of the lower frame 40. The diameter of the pin insertion hole 40a is slightly larger than the diameter of the base of the guide pin 54. Therefore, the lower frame 40 descends along the guide pin 54 and is guided to the fitting portion 53.

[0075] Furthermore, an escape hole 141 is formed at the lower part of the car bottom support beam 14A to avoid interference with the guide pin 54. The diameter of the escape hole 141 is larger than the diameter of the base of the guide pin 54. Alternatively, if the lower part of the car bottom support beam 14A has a structure that does not interfere with the guide pin 54, the escape hole 141 is not required.

[0076] The longitudinal frame 41B (not shown) has the same structure as the longitudinal frame 41B and is formed symmetrically to the longitudinal frame 41B. In addition, a guide pin, the same as the guide pin 54, is provided in the fitting part (not shown) of the longitudinal frame 41B.

[0077] In embodiment 2, the guide pin 54 tapers towards the front end. Therefore, even if the lower frame 40 is slightly offset in the front-rear direction relative to the fitting portion 53, the guide pin 54 can still be inserted into the pin insertion hole 40a. The lower frame 40 is guided to the fitting portion 53 (not shown) by the guide pin 54. As a result, the lower frame 40 can be easily fitted with the fitting portion 53, etc.

[0078] 3. Summary

[0079] As described above, the car 3 of Embodiment 1 includes a car frame 7 having a pair of longitudinal frames 11A and 11B and a lower frame 10 connecting the lower ends of the pair of longitudinal frames 11A and 11B; and a car chamber 8 having a car floor 12 integrally assembled with the lower frame 10. The pair of longitudinal frames 11A and 11B have fitting portions 23 and 27 that fit into the lower frame 10; and tapered plates 24A, 24B, 28A, and 28B (guide portions) that guide the lower frame 10 to the fitting portions 23 and 27. Therefore, the lower frame 10 can be easily fitted into the fitting portions 23 and 27. As a result, the installation of the car 3 can be easily performed.

[0080] Furthermore, the car bottom 12 in Embodiment 1 described above has markings 31 for aligning with the positions of a pair of longitudinal frames 11A and 11B. This allows for easy alignment of the lower frame 10 with the fitting portions 23 and 27.

[0081] Furthermore, the conical pieces 24A, 24B, 28A, and 28B (guide portions) in Embodiment 1 protrude obliquely from the upper ends of the fitting portions 23 and 27. This allows the lower frame 10, located above the fitting portions 23 and 27, to be guided to them. Therefore, by lowering the lower frame 10 (the lower car assembly 30), it can be fitted into the fitting portions 23 and 27.

[0082] Furthermore, the fitting portion 23 in Embodiment 1 described above includes a pair of wall panels 23A and 23B facing each other in the direction opposite to the pair of longitudinal frames 11A and 11B and in a direction orthogonal to the vertical direction, and a base plate 23C continuous with the lower ends of the pair of wall panels 23A and 23B. Conical pieces 24A and 24B are respectively provided at the upper ends of the pair of wall panels 23A and 23B. Therefore, even if the position of the lower frame 10 relative to the fitting portion 23 shifts in either the front-rear direction, the lower frame 10 can still be guided to the fitting portion 23.

[0083] Furthermore, the corners formed by the lower surface and side surfaces of the lower frame 10 in Embodiment 1 are rounded. This allows the lower frame 10 to slide easily on the conical pieces 24A, 24B, 28A, and 28B. Consequently, the lower frame 10 can be easily fitted into the fitting portion 23.

[0084] Furthermore, in Embodiment 2 described above, the guide portion is a guide pin 54 that protrudes from the fitting portion 53 and tapers towards the front end. The lower frame 40 has a pin insertion hole 40a into which the guide pin 54 is inserted. Thus, the lower frame 40, located above the fitting portion 53, can be guided to the fitting portion 53. Therefore, by lowering the lower frame 40 (the lower part of the car assembly), it can be fitted with the fitting portion 53, making the installation of the car 3 easy. Moreover, even if the position of the lower frame 40 relative to the fitting portion 53 is offset in any direction in the horizontal direction, as long as the guide pin 54 can be inserted into the pin insertion hole 40a, the lower frame 10 can be guided to the fitting portion 23.

[0085] The above describes the car and elevator of the present invention, including their effects. However, the car and elevator of the present invention are not limited to the above embodiments, and various modifications can be made without departing from the spirit of the invention as described in the patent claims.

[0086] For example, in Embodiment 1 described above, the mark 31 is provided on the upper surface of the car bottom 12. However, the mark involved in this invention is not limited to being provided on the upper surface of the car bottom 12; for example, it may also be provided on the side of the car bottom, the side of the lower frame, the side of the car bottom support beam, etc. Furthermore, the mark involved in this invention is not limited to two lines; for example, it may be a single line aligned with one end of a pair of longitudinal frames in the front-rear direction. Additionally, the mark involved in this invention is not limited to lines; it may also be an imprint, a mark, a groove, a protrusion, etc.
