Description

  The present invention relates to a car frame of an elevator that supports a car room.

  Conventionally, an elevator structure has been proposed in which the car room is suspended from the upper part of the car frame via a link, and a damper is connected between the car frame and the car room to suppress the amplitude of car shake during an earthquake. ing. The car is less likely to be detached from the guide rail by suppressing the amplitude of the car shake during an earthquake (see Patent Document 1).

JP 54-131235 A

  However, since it is necessary to hang the car room with a link or to connect a damper between the car room and the car frame, the manufacturing cost increases.

  In addition, for example, the thickness of the guide rail that guides the car and the interval between the support brackets that support the guide rail may be adjusted to suppress the amplitude of the car shake during an earthquake. Since it is necessary to make the interval significantly smaller than the floor dimension of the building or to attach a tie bracket that suppresses the deflection of the guide rail between the support brackets, the manufacturing cost also increases in this case.

  The present invention has been made in order to solve the above-described problems, and provides an elevator car frame that can more reliably suppress the amplitude of the car sway and suppress an increase in manufacturing cost. The purpose is to obtain.

  The elevator car frame according to the present invention has a vertical column facing a guide rail that guides the car, and is provided in a middle portion of the car frame main body and the vertical column that supports the car room, and between the guide rail and the vertical column. An intermediate stopper disposed on the vertical column, fixed to the vertical column along the longitudinal direction of the vertical column, and having a predetermined vibration damping capability, and the vibration suppression member sandwiched between the vertical column and the vibration suppression member And a reinforcing member having higher rigidity than the damping member.

  In the elevator car frame according to the present invention, an intermediate stopper is provided at an intermediate portion of the vertical column, a vibration damping member having a predetermined vibration damping capability is fixed to the vertical column, and a reinforcing member is fixed to the vibration suppression member. Therefore, even when the car vibrates in the horizontal direction due to an earthquake or the like, for example, the increase in the car amplitude can be suppressed by the intermediate stopper hitting the guide rail. Also, when the intermediate stopper hits the guide rail and the vertical column bends, shear deformation occurs in the vibration damping member, so that the vibration damping member can exert its vibration damping function, effectively vibrating the cage in the horizontal direction. Can be attenuated. For this reason, the amplitude of the car shake can be more reliably suppressed. Moreover, since the intermediate stopper and the damping member are fixed to the vertical column and the reinforcing member is only fixed to the damping member, an increase in manufacturing cost can be suppressed.

  The car frame body 8 includes a lower frame 9 disposed horizontally below the car room 6, an upper frame 10 disposed above the car room 6, parallel to the lower frame 9, and the lower frame 9 and the upper frame 10. It has a pair of vertical pillars 11 and 12 connecting both ends.

  The car room 6 is placed on the lower frame 9. Moreover, the cab 6 is arranged between one vertical column 11 and the other vertical column 12 in the horizontal direction.

  One vertical column 11 is disposed along the vertical direction while facing one guide rail 2. One vertical column 11 is provided with a vertical column groove 11 a along the length direction of the one vertical column 11. One vertical column 11 is arranged between the car room 6 and the one guide rail 2 with the vertical column groove 11 a facing the one guide rail 2.

The other vertical column 12 is provided with a vertical column groove 12 a along the length direction of the other vertical column 12. The other vertical column 12 is arranged between the car room 6 and the other guide rail 3 with the vertical column groove 12 a facing the other guide rail 3.

  As shown in FIG. 1, a guide device 13 guided by one guide rail 2 is attached to each of the upper end portion and the lower end portion of one vertical column 11. Each guide device 13 is provided with a guide groove 14 into which a part of one guide rail 2 is inserted.

  A guide device 15 guided by the other guide rail 3 is attached to each of the upper end portion and the lower end portion of the other vertical column 12. Each guide device 15 is provided with a guide groove 16 into which a part of the other guide rail 3 is inserted.

  When the car 1 is moved, a part of one guide rail 2 is inserted into each guide groove 14 and a part of the other guide rail 3 is inserted into each guide groove 16. , 15 are guided to the guide rails 2, 3.

  A plate-like intermediate stopper 17 that protrudes from the vertical column 11 toward the one guide rail 2 is provided at an intermediate portion of the one vertical column 11. In this example, the intermediate stopper 17 is disposed at a position where the distance from each of the guide devices 13 attached to the upper end portion and the lower end portion of one vertical column 11 is equal (the central position of the vertical column 11). The intermediate stopper 17 is fixed horizontally in the vertical column groove 11a. The intermediate stopper 17 is provided with a notch 18. A part of one guide rail 2 is inserted inside the notch 18 via a gap.

  A plate-shaped intermediate stopper 19 (FIG. 2) that protrudes from the vertical column 12 toward the other guide rail 3 is provided at the intermediate portion of the other vertical column 12. In this example, the intermediate stopper 19 is disposed at a position where the distance from each of the guide devices 15 attached to the upper end portion and the lower end portion of the other vertical column 12 is equal (the central position of the vertical column 12). The intermediate stopper 19 is fixed horizontally in the vertical column groove 12a. The intermediate stopper 19 is provided with a notch 20. A part of the other guide rail 3 is inserted inside the notch 20 through a gap.

  A pair of damping members 21 are fixed to one vertical column 11 along the length direction of the one vertical column 11. Each damping member 21 is a member having a vibration damping capability (predetermined vibration damping capability) higher than that of one vertical column 11. As a material constituting each vibration damping member 21, for example, rubber or plastic is used.

  On one vertical column 11, the entire surface of the damping member 21 that contacts the vertical column 11 is affixed. This prevents displacement (displacement or slipping) of the vibration damping member 21 relative to one vertical pillar 11 at any position on the boundary between the vibration damping member 21 and the vertical pillar 11.

  One vertical column 11 has each damping member in a direction (width direction of the vertical column 11) perpendicular to a common plane (vertical surface along the width direction of the car 1) including the vertical columns 11 and 12, respectively. 21. The length of each damping member 21 is shorter than the length of one vertical column 11. The intermediate stopper 17 is arranged within the range of the length of each damping member 21.

  A reinforcing member 22 having higher rigidity than that of the damping member 21 is fixed to each damping member 21 along the length direction of the damping member 21. As a material constituting the reinforcing member 22, for example, iron or the like is used. In this example, the reinforcing member 22 is a rod-shaped member having a rectangular cross section.

  All the surfaces of the reinforcing member 22 that come into contact with the vibration damping member 21 are attached to the vibration damping member 21. This prevents displacement (displacement or slippage) of the reinforcing member 22 relative to the damping member 21 at any position on the boundary between the reinforcing member 22 and the damping member 21.

  Each reinforcing member 22 sandwiches the damping member 21 between one vertical column 11. Thereby, one vertical pillar 11 and each damping member 21 are put together by each reinforcing member 22 in the width direction of the vertical pillar 11. The length of each reinforcing member 22 is the same as the length of the damping member 21.

  The damping member 21 and the reinforcing member 22 are provided on one vertical column 11 as follows. That is, after supporting the reinforcing member 22 in a state of being separated from one vertical column 11 by a predetermined interval, the space between the one vertical column 11 and the reinforcing member 22 is surrounded by a mold frame, and is surrounded by the mold frame. The material of the damping member 21 is poured into the space. When the material poured into the space is solidified as the vibration damping member 21, the vibration damping member 21 and the reinforcing member 22 are provided on one vertical column 11. In this example, the damping member 21 is fixed to each of the one vertical column 11 and the reinforcing member 22 by vulcanization adhesion.

  A pair of damping members 23 are fixed to the other vertical column 12, and a reinforcing member 24 is fixed to each of the damping members 23. The material constituting each damping member 23 is the same as the material constituting the damping member 21 described above. The material constituting each reinforcing member 24 is the same as the material constituting the reinforcing member 22 described above. The fixing position and fixing method of the damping member 23 with respect to the other vertical column 12 are the same as the fixing position and fixing method of the damping member 21 with respect to the one vertical column 11. The fixing position and fixing method of the reinforcing member 24 with respect to the damping member 23 are the same as the fixing position and fixing method of the reinforcing member 22 with respect to the damping member 21.

  The car frame 7 includes a car frame main body 8, intermediate stoppers 17 and 19, vibration damping members 21 and 23, and reinforcing members 22 and 24.

  Next, the operation when the car 1 is vibrating in the horizontal direction due to, for example, an earthquake will be described. FIG. 3 is a partially broken side view showing a state when the car 1 of FIG. 1 is vibrating horizontally in the hoistway. FIG. 4 is a horizontal sectional view showing the elevator apparatus of FIG. The car 1 is moved while passing through the position of each rail bracket 4. Accordingly, the positions of the guide devices 13 and 15 with respect to the rail bracket 4 change as the car 1 moves.

  For example, when the car 1 vibrates toward one of the guide rails 2 and each guide device 13 is pressed against the one guide rail 2 as shown in FIG. 3, the one guide rail 2 applies a force in the horizontal direction to each guide. Receive from device 13. Thereby, one guide rail 2 bends at the position of each guide device 13. At this time, when the position of the rail bracket 4 is the position of the substantially central height between the guide devices 13, the distance between the position of each guide device 13 and the position of the rail bracket 4 increases. The deflection of one guide rail 2 is increased at the position of each guide device 13.

  When the deflection of one guide rail 2 increases and reaches a predetermined size, the intermediate stopper 17 hits one guide rail 2. Accordingly, one guide rail 2 receives a force in the horizontal direction from the intermediate stopper 17. At this time, since the rail bracket 4 is located at substantially the same height as the height of the intermediate stopper 17, one guide rail 2 is not easily bent at the position of the intermediate stopper 17. The vertical column 11 will bend. The dimension of the intermediate stopper 17 is adjusted so that each guide device 15 does not come off from the other guide rail 3 when one vertical column 11 is bent.

  When one vertical column 11 bends, each damping member 21 is subjected to shear deformation while being fixed to the reinforcing member 22. When each damping member 21 is subjected to shear deformation, the vibration of the car 1 in the horizontal direction is attenuated by the vibration damping function of each damping member 21.

  FIG. 5 is a horizontal sectional view showing a state in which the intermediate stopper 19 is in contact with the other guide rail 3 of FIG. Even when the car 1 vibrates toward the other guide rail 3 and the intermediate stopper 19 hits the other guide rail 3, each car 1 vibrates toward the one guide rail 2 as in the above case. The vibration of the car 1 in the horizontal direction is damped by the vibration damping function of the damping member 23. The dimension of the intermediate stopper 19 is also adjusted so that each guide device 13 does not come off from one guide rail 2 when the other vertical column 12 is bent.

  In such an elevator car frame 7, intermediate stoppers 17 and 19 are provided in the middle of the vertical columns 11 and 12, and damping members 21 and 23 having a predetermined vibration damping capability are fixed to the vertical columns 11 and 12. In addition, since the reinforcing members 22 and 24 are fixed to the vibration damping members 21 and 23, the intermediate stoppers 17 and 19 are connected to the guide rails 2 even when the car 1 vibrates in the horizontal direction due to, for example, an earthquake. , 3 can suppress an increase in the amplitude of the car 1. Further, when the intermediate stoppers 17 and 19 come into contact with the guide rails 2 and 3 and the vertical pillars 11 and 12 are bent, the vibration damping members 21 and 23 are sheared, so that the vibration damping members 21 and 23 exhibit a vibration damping function. And the vibration of the car 1 in the horizontal direction can be effectively damped. For this reason, the amplitude of the car shake can be more reliably suppressed, and the guide devices 13 and 15 can be prevented from being detached from the guide rails 2 and 3. Further, since the intermediate stoppers 17 and 19 and the damping members 21 and 23 are fixed to the vertical columns 11 and 12 and the reinforcing members 22 and 24 are only fixed to the damping members 21 and 23, an increase in manufacturing cost is suppressed. You can also.

  Further, since the intermediate stoppers 17 and 19 are provided with notches 18 and 20 in which part of the guide rails 2 and 3 are inserted through a gap, the vibration of the car 1 in the width direction of the hoistway is provided. In addition, the vibration of the car 1 in the depth direction of the hoistway can be effectively suppressed.
