Description

  The present invention relates to an elevator balancing weight device in which a plurality of loading weights are loaded in a frame, and a laminated weight presser thereof.

  In the conventional elevator weight device, the first and second suspension frames, the upper frame connected between the upper ends of the first and second suspension frames, and the first and second suspension frames are provided. A frame is constituted by the lower frame connected between the lower end portions. A plurality of stacked weights are stacked and held in the frame. The laminated weight stacked on the uppermost stage is pressed from the upper surface by a fixture that is inserted into and fixed to the first and second suspension frames (see, for example, Patent Document 1).

  In another conventional counterweight device, a pair of through bolts penetrates all the laminated weights. A presser plate for preventing the lifting of the laminated weight is fixed to the through bolt (for example, see Patent Document 2).

Japanese Patent Laid-Open No. 11-60113 JP 7-315725 A

  In recent years, it is sometimes required to enhance the seismic resistance of the counterweight device when repairing an elevator. As one of the methods for enhancing the earthquake resistance, there is a method in which a stopper for preventing the lifting of the laminated weight is added to the counterweight device.

  On the other hand, when the fixing bracket shown in Patent Document 1 is added to the existing hanging frame, it is necessary to perform processing for fixing the fixing bracket to the existing hanging frame. However, the space between the counterweight device and the hoistway wall is narrow, and it is often impossible to secure a space for inserting tools. For this reason, in order to perform additional processing on the existing suspension frame, it is necessary to remove the guide shoes from the upper frame and the lower frame, twist the counterweight device in the horizontal direction, and secure a processing space. It takes. Further, when changing the amount of the laminated weight, it is necessary to perform a new additional process in order to change the position of the stopper.

  Moreover, since the press plate shown in Patent Document 2 is attached to a through bolt, it is difficult to apply it to an existing counterweight device in which a hole for passing a through bolt is not provided in a laminated weight. is there.

  The present invention has been made to solve the above-described problems, and an elevator counterweight device capable of easily adding a function of preventing the lifting of a laminated weight and a laminated weight presser thereof are obtained. With the goal.

  An elevator counterweight device according to the present invention includes a pair of suspension frames, an upper frame connected between the suspension frames, and a lower frame connected between the suspension frames below the upper frame. A laminated weight, and a laminated weight holder that prevents the laminated weight from being lifted. An upper frame fixing portion fixed to the frame; and a stopper portion that is attached to the upper frame fixing portion and that contacts the upper surface of the laminated weight body to prevent the laminated weight from being lifted. A first attachment metal contacting the upper frame and a second attachment metal sandwiched between the first attachment metal and the first attachment metal by being fixed to the first attachment metal by a fixture. Yes.

  In the elevator counterweight device of the present invention, the upper frame is sandwiched between the first mounting bracket and the second mounting bracket by fixing the second mounting bracket to the first mounting bracket by the fixture. Thus, since the upper frame fixing portion of the laminated weight presser is fixed to the upper frame, a function of preventing the raised weight of the laminated weight can be easily added.

  Each stopper bolt 37 penetrates the bolt mounting portion 36a. Each stopper bolt 37 is combined with a nut or screw hole provided in the bolt mounting portion 36a. By adjusting the amount of screwing into the nut or screw hole, the amount of protrusion of each stopper bolt 37 downward from the bolt mounting portion 36a can be adjusted. By adjusting the protruding amount as described above, the lower end portion of each stopper bolt 37 is in contact with the upper surface of the laminated weight body 22.

  Each third attachment metal vertical portion 36b is fixed to the corresponding second attachment metal vertical portion 35b by a plurality of fixtures 38. As each fixing tool 38, a combination of a bolt and a nut is used. A plurality of holes 35d (FIG. 5) through which the fixing tool 38 is passed are provided in each second attachment metal vertical portion 35b in the vertical direction.

  A plurality of holes 36c (FIG. 5) through which the fixture 38 is passed are provided in each third attachment metal vertical portion 36b in the vertical direction. The number of holes 36c in the third mounting metal vertical portion 36b is larger than the number of holes 35d in the second mounting metal vertical portion 35b. The interval between the holes 36c is the same as the interval between the holes 35d.

  The mounting position of the stopper portion 32 on the upper frame fixing portion 31 can be adjusted in the vertical direction by selecting the hole 36c through which the fixing tool 38 is passed.

  In the counterweight device 10 and the laminated weight presser 25 as described above, the first attachment metal 33 and the second attachment metal are fixed by fixing the second attachment metal 35 to the first attachment metal 33 by the fixture 34. Since the upper frame 27 is sandwiched between the gold 35 and the upper frame fixing portion 31 is fixed to the upper frame 27, the function of preventing the lifting of the laminated weight 29 can be easily performed without drilling the frame body 21. It can be added, and the earthquake resistance of the counterweight device 10 can be enhanced.

Moreover, since the attachment position to the upper frame fixing | fixed part 31 of the stopper part 32 can be adjusted to an up-down direction, it can respond easily to the change of the loading amount of the laminated weight 29. FIG.
Further, the stopper portion 37 is provided with a stopper bolt 37 so that the amount of protrusion of the stopper bolt 37 downward from the third attachment metal 36 can be adjusted, so that the laminated weight body 22 can be pressed more securely. Further, the lifting of the laminated weight 29 can be prevented more reliably.

In the above example, two sets of stacked weight pressers 25 are used, but only one set or three or more sets of stacked weight pressers 25 may be used for one counterweight device 10.
In the above example, the stopper bolt 37 is in direct contact with the laminated weight 29. However, another component that constitutes a part of the laminated weight body 22 is placed on the uppermost laminated weight 29. The stopper bolts 37 may be in contact with each other.
Further, in the above example, the upper frame fixing portion 31 is in contact with the upper surface, the lower surface, the front surface, and the rear surface of the upper frame 27, but the upper frame fixing portion 31 can be fixed to the upper frame 27 and the laminated weight 29 can be lifted. If it can be prevented, there may be a gap between any surface of the upper frame 27 and the upper frame fixing portion 31.
Furthermore, the layout and roping method of the elevator as a whole are not limited to the example of FIG. For example, the present invention can be applied to a 2: 1 roping elevator.
The laminated weight presser of the present invention can also be applied to a new counterweight device.
Further, the present invention can be applied to various types of elevator weight devices such as machine room-less elevators, double deck elevators, and one-shaft multi-car elevators.
