Description

The present invention relates to cars and elevators.

An elevator car has a car chamber and a car frame that supports the car chamber. The car chamber has a floor, a ceiling, and side panels. The car frame is located outside the car chamber and is formed into a rectangular frame that surrounds the floor, ceiling, and side panels.

Patent Document 1 describes technology related to elevator car frame structure. As described in Patent Document 1, the car frame has a bottom frame, an top frame, and left and right vertical frames. When installing the car frame, first the left and right vertical frames are fitted into guide rails. Next, the bottom frame is inserted between them and fixed to the vertical frame. After that, the car chamber is assembled and the top frame is fixed to the left and right vertical frames. Generally, the bottom frame is fitted into the lower parts of the left and right vertical frames while being assembled integrally with the car floor of the car chamber.

JP 2001-114485 A

However, when fitting the lower frame, which is assembled integrally with the car floor, into the vertical frame, the lower frame is hidden by the car floor when viewed from above, making it impossible to see where the lower and vertical frames fit together. As a result, it was difficult to adjust the position of the lower frame relative to the left and right vertical frames, making installation work cumbersome. In addition, to visually check where the lower and vertical frames fit together, workers had to enter the pit and look from below, which was an obstacle to improving safety.

The objective of this project is to provide a car and elevator that takes the above problems into consideration and allows for easy installation.

In order to solve the above problems and achieve the object, the elevator car includes a car frame having a pair of vertical frames and a lower frame connecting lower ends of the pair of vertical frames, and a car chamber having a car floor assembled integrally with the lower frame. The pair of vertical frames have fitting portions into which the lower frames fit, and guide portions that guide the lower frame to the fitting portions.
The elevator also includes the car that moves up and down within the elevator shaft.

According to the car and elevator having the above configuration, installation work can be easily performed.
Problems, configurations and effects other than those described above will become apparent from the following description of the embodiments.

1. First embodiment [Elevator]
First, the configuration of an elevator according to a first embodiment of the present invention will be described with reference to FIG.
FIG. 1 is a schematic configuration diagram of an elevator according to a first embodiment.

As shown in FIG. 1, the elevator includes a hoist 1, a main rope 2, a car 3, a counterweight 5, and a pulley 6. The car 3 includes a pair of under-car pulleys 4A and 4B. The car 3 moves up and down the elevator shaft 100 according to the movement of the main rope 2 wound around the pair of under-car pulleys 4A and 4B.

The hoist 1 is a device that winds up the main rope 2 to raise and lower the car 3. The hoist 1 is installed 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 under-car pulleys 4A, 4B, the hoist 1, and a pulley 6.

The car 3 rises and falls while being guided by a pair of guide rails (not shown). A pair of under-car pulleys 4A, 4B are arranged below the car 3. The counterweight 5 is a weight for reducing the load on the hoist 1 by balancing the mass with the car 3. When the hoist 1 winds up the main rope 2, the counterweight 5 rises and falls in the opposite direction to the car 3. The pulley 6 is arranged above the counterweight 5 and rises and falls together with the counterweight 5.

[Car]
Next, the configuration of the car 3 will be described with reference to FIG.
FIG. 2 is a perspective view showing the appearance of the car 3. As shown in FIG.

In this embodiment, the front-back, up-down, and left-right directions are defined based on the line of sight of the elevator user facing the car 3. In this case, the near side as seen from the elevator user is the forward direction, the far side is the rear, the upper side is the upward direction, the lower side is the downward direction, the left side is the left side, and the right side is the right side.

As shown in FIG. 2, the elevator car 3 includes a car frame 7 and a car chamber 8 arranged inside the car frame 7. The car chamber 8 has an internal storage space for carrying luggage and passengers. The car chamber 8 is formed by a car floor 12, side panels 13, and a ceiling 15. The car floor 12 and the ceiling 15 are arranged to face each other in the vertical direction with the storage space in between. The side panels 13 are arranged to surround the storage space on all four sides, except for the car door 18.

The upper frame 9 is a member that extends elongately in the left-right direction. The upper frame 9 is horizontally suspended between the upper ends of a pair of vertical frames 11A, 11B. One longitudinal end of the upper frame 9 is fixed to the upper end of the vertical frame 11A, and the other longitudinal end of the upper frame 9 is fixed to the upper end of the vertical frame 11B. As a result, the upper ends of the pair of vertical frames 11A, 11B are connected by the upper frame 9.

The pair of vertical frames 11A, 11B are arranged facing each other in the left-right direction. Each of the vertical frames 11A, 11B is a member that extends long in the up-down direction. Each of the vertical frames 11A, 11B is supported movably by the pair of guide rails described above. The guide rails are long members that are installed vertically on the walls of the elevator shaft 100.

The lower frame 10 is disposed in a position facing the upper frame 9 across the cage 8. The lower frame 10 is a substantially rectangular parallelepiped member that extends long in the left-right direction (see FIG. 5). The corners formed by the lower surface and side surfaces of the lower frame 10 are formed in an arc shape.

The lower frame 10 is horizontally suspended between the lower ends of a pair of vertical frames 11A and 11B. One longitudinal end of the lower frame 10 is fixed to the lower end of the vertical frame 11A, and the other longitudinal end of the lower frame 10 is fixed to the lower end of the vertical frame 11B. As a result, the lower ends of the pair of vertical frames 11A and 11B are connected by the lower frame 10.

The lower frame 10 supports the car floor 12 via a pair of floor support beams 14A, 14B. The pair of floor support beams 14A, 14B are beams that support the car floor 12. An anti-vibration section 20 is provided at each of the longitudinal ends of the floor support beam 14A, and an anti-vibration section 20 is also provided at each of the longitudinal ends of the floor support beam 14B. The anti-vibration section 20 is a section that suppresses vibrations of the car room 8 including the car floor 12. The car floor 12 is supported by the pair of floor support beams 14A, 14B via multiple (four in this embodiment) anti-vibration sections 20.

The floor support beam 14A is disposed at one end (right end) of the lower frame 10 in the longitudinal direction. The floor support beam 14B is disposed at the other end (left end) of the lower frame 10 in the longitudinal direction. Each floor support beam 14A, 14B is fixed to the upper surface of the lower frame 10 by a bolt (not shown) while placed on the lower frame 10. Each floor support beam 14A, 14B is disposed horizontally and perpendicular to the lower frame 10. Specifically, the lower frame 10 is disposed parallel to the left-right direction, and each floor support beam 14A, 14B is disposed parallel to the front-to-rear direction.

A car door 18 is installed at the front of the car chamber 8. The car door 18 is capable of opening and closing in the left-right direction. A pair of under-car pulleys 4A, 4B are arranged below the car chamber 8 (see FIG. 1 for 4B). The under-car pulleys 4A, 4B are arranged forward of the vertical frames 11A, 11B. One under-car pulley 4A is attached to a floor support beam 14A, and the other under-car pulley 4B is attached to a floor support beam 14B.

[A pair of vertical frames]
Next, the configuration of the pair of vertical frames 11A, 11B will be described with reference to FIG.
FIG. 3 is a perspective view of a pair of vertical frames 11A and 11B.

As shown in FIG. 3, the vertical frame 11A has a vertical frame body 21, a connecting member 22, and a fitting portion 23. The vertical frame body 21 extends vertically. The vertical frame body 21 has two side portions 21A, 21B that face each other in the front-to-rear direction, and a main body plate 21C that is continuous with the two side portions 21A, 21B. The main body plate 21C faces the car chamber 8. The two side portions 21A, 21B protrude approximately vertically from both ends of the main body plate 21C toward the opposite side of the car chamber 8.

The connecting member 22 is disposed directly above the under-car pulley 4A, and connects the vertical frame 11A and the floor support beam 14A (see FIG. 2). The connecting member 22, like the vertical frame body 21, is made of a bent member having a substantially U-shaped cross section parallel to the horizontal direction. The connecting member 22 has a first plate portion disposed parallel to the body plate 21C of the vertical frame body 21, and a second plate portion and a third plate portion continuous with the first plate portion.

The second and third plate portions of the connecting member 22 face each other in the front-to-rear direction. The second plate portion of the connecting member 22 is fixed to the side portion 21A of the vertical frame body 21 using a bolt (screw). The third plate portion of the connecting member 22 is fixed to the floor support beam 14A via an intermediate member (not shown).

The fitting portion 23 is fixed to the lower part of the vertical frame body 21. The fitting portion 23 is disposed on the surface of the vertical frame 11A facing the vertical frame 11B. One end of the lower frame 10 (see Figure 5) in the longitudinal direction is fitted from above into the fitting portion 23.

The fitting portion 23 is an integral structure obtained by bending a metal plate. The fitting portion 23 has a pair of wall panels 23A, 23B facing each other in the front-to-rear direction, and a bottom panel 23C having a plane that is approximately perpendicular to the up-down direction. The pair of wall panels 23A, 23B are formed into an approximately rectangular shape, with the two long sides forming the upper and lower ends. The pair of wall panels 23A, 23B are fixed to the two side portions 21A, 21B of the vertical frame 11A using bolts (screws).

The bottom plate 23C is formed in a substantially rectangular shape. Two sides of the bottom plate 23C facing each other in the front-rear direction are continuous with the lower ends of the pair of wall plates 23A, 23B. One longitudinal end of the lower frame 10 (see FIG. 5) is fixed to the bottom plate 23C using bolts (screws).

Tapered pieces 24A and 24B are provided at the upper ends of the pair of wall panels 23A and 23B, respectively. Tapered pieces 24A and 24B are a specific example of a guide portion according to the present invention. Tapered pieces 24A and 24B protrude obliquely from the upper ends of the pair of wall panels 23A and 23B. Tapered pieces 24A and 24B are made of plates that are continuous with the pair of wall panels 23A and 23B.

The tapered pieces 24A, 24B are inclined so that they move away from each other as they approach the tips opposite the pair of wall panels 23A, 23B. The inclined surfaces (hereinafter referred to as "guide surfaces") of the tapered pieces 24A, 24B that face diagonally upward guide one longitudinal end of the lower frame 10 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 surfaces of the tapered pieces 24A, 24B. An anti-friction material such as grease or lubricating oil may be applied to the guide surfaces of the tapered pieces 24A, 24B.

The vertical frame 11B has a vertical frame body 25, a connecting member 26, and a fitting portion 27. The vertical frame body 25 has the same configuration as the vertical frame body 21 of the vertical frame 11A described above, and has two side portions 25A, 25B, and a body plate 25C that is continuous with the two side portions 25A, 25B. The connecting member 26 has the same configuration as the connecting member 22 of the vertical frame 11A described above. The connecting member 26 is disposed directly above the under-car pulley 4B, and connects the vertical frame 11B to the floor support beam 14B (see FIG. 5).

The fitting portion 27 has the same configuration as the fitting portion 23 of the vertical frame 11A described above, and is fixed to the lower part of the vertical frame main body 25. The fitting portion 27 is disposed on the vertical frame 11A side of the vertical frame 11B. The other end of the lower frame 10 (see FIG. 5) in the longitudinal direction is fitted into the fitting portion 27 from above. The fitting portion 23 has a pair of wall panels 27A, 27B and a bottom panel 27C.

Tapered pieces 28A and 28B are provided at the upper ends of the pair of wall panels 27A and 27B, respectively. Tapered pieces 28A and 28B, together with the above-mentioned tapered pieces 24A and 24B, are a specific example of a guide portion according to the present invention. Tapered pieces 28A and 28B protrude obliquely from the upper ends of the pair of wall panels 27A and 27B. Tapered pieces 28A and 28B are made of plates that are continuous with the pair of wall panels 27A and 237.

The tapered pieces 28A, 28B are inclined so that they move away from each other as they approach the tips opposite the pair of wall panels 27A, 27B. The inclined surfaces (hereinafter referred to as "guide surfaces") of the tapered pieces 28A, 28B that face diagonally upward guide the other end of the lower frame 10 in the longitudinal direction 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 surfaces of the tapered pieces 28A, 28B. An anti-friction material such as grease or lubricating oil may be applied to the guide surfaces of the tapered pieces 28A, 28B.

[Installation of car]
Next, the installation work of the car 3 will be described.
Fig. 4 is an explanatory diagram showing a state in which the car lower assembly according to the first embodiment is being attached to a pair of vertical frames, as viewed from above. Fig. 5 is an explanatory diagram showing a state in which the car lower assembly is being attached to a pair of vertical frames, as viewed from below. Fig. 6 is a cross-sectional view taken along line A-A shown in Fig. 4.

As shown in Figures 4 and 5, the lower frame 10 of the car 3, a pair of floor support beams 14A, 14B, and the car floor 12 are assembled together and transported to the installation site as the car lower assembly 30. When installing the car 3, first, the pair of vertical frames 11A, 11B are attached to guide rails (not shown). At this time, the pair of vertical frames 11A, 11B are fixed to the guide rails. Then, after the car 3 is assembled, the car frame 7 is made movable relative to the guide rails.

Next, the car lower assembly 30 is placed above the fitting parts 23, 27 of the pair of vertical frames 11A, 11B. As shown in FIG. 4, the upper surface of the car floor 12 of the lower assembly 30 is formed with marks 31 for alignment with the pair of vertical frames 11A, 11B. The marks 31 are provided on both sides of the car floor 12 that face each other in the left-right direction.

The markers 31 are two lines that extend left and right with a specified distance between them in the front-to-rear direction. The distance between the two lines is equal to the length of the pair of vertical frames 11A, 11B in the front-to-rear direction. When looking at the lower assembly 30 from above, the worker aligns the two lines of the markers 31 with both ends of the pair of vertical frames 11A, 11B in the front-to-rear direction. This makes it easy to align the front-to-rear position of the lower frame 10 relative to the mating portions 23, 27, as shown in FIG. 6.

Next, the car lower assembly 30 is lowered to fit both longitudinal ends of the lower frame 10 into the fitting portions 23, 27 of the pair of vertical frames 11A, 11B. At this time, if the position of the lower frame 10 in the front-to-rear direction is slightly misaligned with respect to the fitting portions 23, 27, the corners formed by the lower surface and side surface of the lower frame 10 will come into contact with the tapered pieces 24A, 24B, 28A, 28B of the pair of vertical frames 11A, 11B. Then, both longitudinal ends of the lower frame 10 are guided to the fitting portions 23, 27 by the tapered pieces 24A, 24B, 28A, 28B. As a result, the lower frame 10 can be easily fitted into the fitting portions 23, 27.

Figure 7 is an explanatory diagram showing the state in which the car lower assembly 30 is attached to a pair of vertical frames 11A, 11B, as viewed from above. Figure 8 is a cross-sectional view along line B-B shown in Figure 7.

As shown in Figures 7 and 8, after fitting the lower frame 10 into the fitting parts 23, 27, both longitudinal ends of the lower frame 10 are fixed to the bottom plates 23C, 27C of the fitting parts 23, 27 using bolts (screws). Next, the pair of floor support beams 14A, 14B of the car lower assembly 30 are fixed to the connecting members 22, 26 of the pair of vertical frames 11A, 11B via intermediate members. This allows the car lower assembly 30 to be attached to the pair of vertical frames 11A, 11B.

Next, the four side panels 13 are fixed to the car floor 12, and the ceiling 15 is fixed onto the four side panels 13. This completes the assembly of the car room 8 (see Figure 2). Next, both longitudinal ends of the upper frame 9 are fixed to the upper ends of the vertical frames 11A and 11B using bolts (screws). This completes the assembly of the car frame 7, and the installation of the car 3 is completed.

2. Second embodiment Next, an elevator according to a second embodiment of the present invention will be described. The elevator according to the second embodiment has a similar configuration to the elevator according to the first embodiment described above. The elevator according to the second embodiment differs from the elevator according to the first embodiment only in the car frame 7A. Therefore, here, only the car frame 7A will be described, and a description of the configuration common to the first embodiment will be omitted.

[Basket frame]
FIG. 9 is a cross-sectional view showing the fitting state of the lower frame and a pair of vertical frames according to the second embodiment.
As shown in Fig. 9, the car frame 7A according to the second embodiment has a lower frame 40 arranged at the bottom of the car chamber 8, a pair of vertical frames 41A, 41B (vertical frame 41A is shown in Fig. 9) arranged on the left and right sides of the car chamber 8, and an upper frame 9 (not shown) arranged at the top of the car chamber 8. The upper frame 9 is the same as in the first embodiment. The car frame 7A is formed in a vertically long rectangle when viewed from the front-to-rear direction.

The lower frame 40 is a generally rectangular parallelepiped member that extends long in the left-right direction. The lower frame 40 is horizontally suspended between the lower ends of a pair of vertical frames 41A, 41B. One end of the lower frame 40 in the longitudinal direction is fixed to the lower end of the vertical frame 41A, and the other end of the lower frame 40 in the longitudinal direction is fixed to the lower end of the vertical frame 41B. As a result, the lower ends of the pair of vertical frames 41A, 41B are connected by the lower frame 40. The lower frame 40 also supports the car floor 12 (not shown in FIG. 9) via a pair of floor support beams 14A, 14B.

The vertical frame 41A has a vertical frame body 51, a connecting member 22 (not shown) the same as in the first embodiment, and a fitting portion 53. The vertical frame body 51 extends long in the vertical direction. The vertical frame body 51 has two side portions 51A, 51B that face each other in the front-to-rear direction, and a main body plate 51C that is continuous with the two side portions 51A, 51B. The main body plate 51C faces the car chamber 8. The two side portions 51A, 51B protrude substantially perpendicularly from both side ends of the main body plate 51C to the side opposite the car chamber 8. The connecting member 22 (not shown) connects the vertical frame 41A to the floor support beam 14A.

The fitting portion 53 is fixed to the lower part of the vertical frame body 51. The fitting portion 53 is disposed on the surface of the vertical frame 41A facing the vertical frame 41B. One end of the lower frame 40 in the longitudinal direction is fitted into the fitting portion 53 from above. The fitting portion 53 has the same configuration as the fitting portion 23 according to the first embodiment, and has a pair of wall panels 53A, 53B and a bottom panel 53C.

A guide pin 54 extending in the vertical direction is attached to the upper surface of the bottom plate 53C. The guide pin 54 represents another specific example of a guide portion according to the present invention. The guide pin 54 becomes thinner toward the tip. The tip of the guide pin 54 protrudes above the fitting portion 53. The guide pin 54 guides one end of the lower frame 40 in the longitudinal direction to the fitting portion 53.

As shown in FIG. 9, a pin insertion hole 40a into which the guide pin 54 is inserted is formed on the underside 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 is guided into the fitting portion 53 by descending along the guide pin 54.

In addition, an escape hole 141 is formed in the lower part of the floor 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. Note that if the lower part of the floor support beam 14A is designed not to interfere with the guide pin 54, the escape hole 141 is not necessary.

Vertical frame 41B (not shown) has the same configuration as vertical frame 41B and is formed symmetrically with vertical frame 41B. In addition, a guide pin similar to guide pin 54 is provided in the fitting portion (not shown) of vertical frame 41B.

In the second embodiment, the guide pin 54 becomes thinner toward the tip. Therefore, even if the position of the lower frame 40 relative to the fitting portion 53 is slightly misaligned in the front-to-rear direction, the guide pin 54 can be inserted into the pin insertion hole 40a. The lower frame 40 is then guided to the fitting portion 53 (fitting portion not shown) by the guide pin 54 (guide pin not shown). As a result, the lower frame 40 can be easily fitted into the fitting portion 53, etc.

3. Summary As described above, the car 3 of the first embodiment described above includes a pair of vertical frames 11A, 11B and a car frame 7 having a lower frame 10 that connects the lower ends of the pair of vertical frames 11A, 11B, and a car chamber 8 having a car floor 12 that is assembled integrally with the lower frame 10. The pair of vertical frames 11A, 11B have fitting portions 23, 27 into which the lower frame 10 fits, and tapered pieces 24A, 24B, 28A, 28B (guide portions) that guide the lower frame 10 to the fitting portions 23, 27. This allows the lower frame 10 to be easily fitted into the fitting portions 23, 27. As a result, the installation work of the car 3 can be easily performed.

The car floor 12 in the first embodiment described above also has a mark 31 for alignment with the pair of vertical frames 11A, 11B. This makes it easy to align the position of the lower frame 10 with the fitting portions 23, 27.

In addition, the tapered pieces 24A, 24B, 28A, 28B (guide parts) in the first embodiment described above protrude obliquely from the upper ends of the fitting parts 23, 27. This allows the lower frame 10 located above the fitting parts 23, 27 to be guided to the fitting parts 23, 27. Therefore, the lower frame 10 (car lower assembly 30) can be lowered to fit into the fitting parts 23, 27.

The fitting portion 23 in the first embodiment described above has a pair of wall panels 23A, 23B that face each other in the direction in which the pair of vertical frames 11A, 11B face each other and in a direction perpendicular to the up-down direction, and a bottom panel 23C that is continuous with the lower ends of the pair of wall panels 23A, 23B. The tapered pieces 24A, 24B are provided on the upper ends of the pair of wall panels 23A, 23B, respectively. This allows the lower frame 10 to be guided into the fitting portion 23 even if the position of the lower frame 10 relative to the fitting portion 23 is shifted in either the front-to-rear direction.

In addition, the corners formed by the underside and side surfaces of the lower frame 10 in the first embodiment described above are formed in an arc shape. This makes it easier for the lower frame 10 to slide over the tapered pieces 24A, 24B, 28A, and 28B. As a result, the fitting operation of the lower frame 10 to the fitting portion 23 can be made easier.

The guide portion in the second embodiment described above is a guide pin 54 that protrudes from the fitting portion 53 and becomes thinner toward the tip. The lower frame 40 has a pin insertion hole 40a into which the guide pin 54 is inserted. This allows the lower frame 40 above the fitting portion 53 to be guided to the fitting portion 53. Therefore, by lowering the lower frame 40 (car lower assembly), it can be fitted into the fitting portion 53, making it easy to install the car 3. Even if the position of the lower frame 40 relative to the fitting portion 53 is shifted in any horizontal direction, the lower frame 10 can be guided to the fitting portion 23 as long as the guide pin 54 can be inserted into the pin insertion hole 40a.
