Description

  The present invention relates to a support device for a hoisting machine for an elevator, and more particularly to a support device for a hoisting machine that restricts the movement of the hoisting machine in the event of an earthquake.

  In the conventional elevator hoisting machine support device, the anti-vibration rubber is inserted between the base receiver and the machine beam, the anti-vibration rubber upper plate and the base receiver are fixed by bolts, the anti-vibration rubber lower plate and the machine beam. Are fixed by bolts, and the stopper bolt mounting seat is fixed to the vibration isolating rubber lower plate by welding or the like so that the stopper bolt mounting seat is located at the center of the vibration isolating rubber, and the stopper bolt penetrates through the hole formed in the base support. It is attached to a bolt mounting seat (for example, see Patent Document 1).

  In a conventional elevator hoisting machine support device, the stopper bolt is inserted into a hole formed in the base receiver so as to be loosely fitted. Therefore, when the hoisting machine moves in the horizontal direction, the vertical direction, or the rotating direction, the stopper bolt The shaft portion of the winder is in contact with a hole formed in the base receiver, or the head of the stopper bolt is in contact with the base receiver, and the movement of the hoisting machine in the horizontal direction, the vertical direction, and the rotational direction is restricted. Therefore, the vibration-proof rubber is not excessively deformed, the vibration-proof rubber is prevented from being damaged or broken, and the hoisting machine is prevented from falling due to the vibration-proof rubber being broken or the like.

JP 58-74485 A

  In the conventional elevator hoist support device, the stopper bolt mounting seat is disposed at the center of the anti-vibration rubber, which complicates the anti-vibration rubber structure and increases the cost.

  In addition, since the hole for installing the stopper bolt mounting seat is formed in the center of the anti-vibration rubber, to ensure the same anti-vibration performance as the anti-vibration rubber without holes, the diameter of the anti-vibration rubber is It gets bigger by the minute. Furthermore, the vibration isolator rubber becomes larger, and the vibration isolator rubber upper plate and lower plate become larger, which increases the size of the support device. Further, in the conventional support device, since the stopper bolt for restricting movement is a separate part from the bolt for fixing the vibration isolating rubber upper plate to the base receiver, it is necessary to form a hole through which the stopper bolt is inserted in the base receiver.

  Therefore, if a conventional support device is installed instead of an existing support device that does not have a mechanism for restricting the movement of the hoisting machine in the horizontal direction, the vertical direction, and the rotation direction, an interference with the wall of the building occurs. Or additional drilling is required, and the installation workability is reduced.

  The present invention has been made to solve such a problem, and is used to move the hoisting machine using a spacer that is fixed to the upper plate of the antivibration rubber and connects the antivibration rubber and the hoisting machine base. It is an object of the present invention to provide an elevator hoisting machine support device that can regulate the vibration-proof rubber structure, simplify the vibration-proof rubber structure, reduce the size of the anti-vibration rubber structure, and reduce mounting holes for the hoisting machine base.

  A support device for an elevator hoisting machine according to the present invention is configured by sandwiching a rubber material between an upper seat plate and a lower seat plate, and placing the lower seat plate on a flange of a machine base. Rubber, fastening means for fastening and fixing the lower seat plate to the flange, and one end fixed to the upper seat plate with its axial direction coinciding with the center of the anti-vibration rubber, and standing on the upper seat plate, The other end has a cylindrical spacer fixed to the hoisting machine base, a movement restricting hole, is fixed to the lower seat plate, extends between the upper seat plate and the hoisting machine base, and the spacer Is provided with a movement restricting plate inserted into the movement restricting hole in a loosely fitted state.

  According to this invention, the movement restricting hole is formed in the movement restricting plate that is fixed to the lower seat plate and extends between the upper seat plate and the hoisting machine base, and the spacer that connects the upper seat plate and the hoisting machine base is moved. The movement of the hoisting machine is regulated by inserting the regulation hole in a loosely fitted state. Therefore, since the anti-vibration rubber does not constitute a movement restricting mechanism, the structure of the anti-vibration rubber can be simplified, and the cost and size can be reduced.

  In addition, since the spacer that transmits the vibration of the hoisting machine to the anti-vibration rubber also serves as a member that abuts against the inner wall surface of the movement restricting hole and restricts the movement of the hoisting machine, a mounting hole formed on the hoisting machine base Is only a bolt insertion hole for fastening and fixing the spacer. Thereby, when installing this support device instead of the existing support device that does not have a mechanism for restricting the movement of the hoisting machine, the hole formed in the hoisting machine base for attaching the existing support device can be diverted. No additional drilling is required, improving installation workability. In addition, since the vibration isolation mechanism and the movement restricting mechanism are coaxial, an increase in the radial dimension of the support device can be suppressed and the size can be reduced, so that the installed support device may interfere with the building wall. Absent.

The machine base 5 is made of H-shaped steel, arranged in parallel, and fixed to the machine room floor 6 above the hoistway 8 with anchor bolts (not shown). The hoisting machine base 3 is placed on one machine base 5 on one side of the T-shape, and the extending end of the other side extending from the center of one side is placed on the other machine base 5. The hoisting machine base 3 is supported by the machine base 5 via the support device 10 at the two ends of one side of the T-shape and the tip of the other side.

  The support device 10 connects the anti-vibration rubber 11 attached to the flange 5a of the machine base 5, the fastening means for fastening the anti-vibration rubber 11 to the flange 5a, and the anti-vibration rubber 11 and the hoisting machine base 3. A spacer 16 and a movement restricting plate 18 that engages with the spacer 16 and restricts the movement of the hoist 1 due to an earthquake or the like are provided.

  The anti-vibration rubber 11 includes a cylindrical rubber member 12, a rectangular flat plate lower base plate 13 fixed to the lower surface of the rubber member 12, and a circular flat upper member fixed to the upper surface of the rubber member 12. And a plate 15. Mounting through holes 14 are formed at the four corners of the lower seat plate 13. The spacer 16 is formed in a columnar shape, and is fixed to the upper seat plate 15 by welding or the like, and is erected coaxially with the axis of the rubber material 12. The female screw portion 17 is formed at the axial center position of the spacer 16 with the screw hole direction as the axial direction.

  The movement restricting plate 18 is formed in a rectangular flat plate shape and has a notch 19 as a movement restricting hole. The notch 19 has a groove width larger than the diameter of the spacer 16 and is formed in a hole shape having one end opened at the center of the edge of one side of the movement restricting plate 18 and a semicircular bottom at the other end. . Further, the mounting through-hole 20 is formed at the edge of the side opposite to the bottom of the notch 19 of the movement restricting plate 18 so as to be separated in the length direction of the side.

  The clip member 21 is formed in an L shape having a base portion 21a and a sandwiching portion 21b extending from one side in the thickness direction of the base portion 21a, and the through hole 22 is formed so as to penetrate the base portion 21a in the thickness direction. ing. The clip member 21, the mounting bolts 23a and 23b, and the nut 24 constitute fastening means. The shaft portion of the mounting bolt 23a is longer than the shaft portion of the mounting bolt 23b.

  The anti-vibration rubber 11 is placed on the flange 5a of the machine base 5, the base portion 21a of the clip member 21 is directed to the lower surfaces of the four corners of the lower seat plate 13, and the flange 5a is connected to the lower seat plate 13 and the sandwiching portion 21b. The mounting bolts 23a and 23b are inserted into the through hole 22 formed in the base 21a of the clip member 21 and the through hole 14 formed in the lower seat plate 13, and the mounting bolts 23a and 23b and the nut 24 are tightened. It is fixed to the machine base 5. The two mounting bolts 23 a extend in parallel so that the shaft portion passes through the outside of the upper seat plate 15 and faces the spacer 16.

  Then, the movement restricting plate 18 is positioned so that the center of the semicircular bottom portion of the notch 19 is aligned with the axis of the vibration isolating rubber 11 through the mounting bolt 23a through the through hole 20, and sandwiches the movement restricting plate 18 therebetween. In this manner, the pair of nuts 24 screwed to the shaft portion of the mounting bolt 23a are fastened and fixed to the two mounting bolts 23a. As a result, the spacer 16 is accommodated in the notch 19 such that its axis coincides with the center of the semicircular bottom of the notch 19. Further, a mounting bolt (not shown) is passed through a through hole (not shown) formed in the hoisting machine base 3 and fastened to the female screw portion 17, and the hoisting machine base 3 is connected to the machine base via the support device 10. 5 is supported.

  Here, the movement restricting plate 18 of the supporting device 10 that supports both ends of one side of the T-shape of the hoisting machine base 3 extends in the U-shaped groove depth direction of the notch 19 in the T-shape of the hoisting machine base 3. Is arranged in parallel with the extending direction of the other side extending from the center of one side, and the opening of the notch 19 is arranged toward the extending end side of the other side of the T-shape of the hoisting machine base 3. . Further, the movement restricting plate 18 of the support device 10 that supports the extending portion of the other side of the T-shape of the hoisting machine base 3 extends in the U-shaped groove depth direction of the notch 19 in the T-shape of the hoisting machine base 3. The other side of the winding is parallel to the extending direction, and the opening of the notch 19 is disposed toward one side of the T-shape of the hoisting machine 3.

  Further, the through hole 20 is formed as an elongated hole in which both ends of two parallel lines are connected by a semicircle, and the movement restricting plate 18 is positioned at the center of the semicircular bottom of the notch 19 with the axis of the spacer 16 being centered. Thus, the position is adjusted and fixed to the mounting bolt 23a.

Next, the operation of the support device 10 will be described.
First, vibration generated in the hoisting machine 1 is transmitted to the anti-vibration rubber 11 through the hoisting machine base 3 and the spacer 16. The vibration is absorbed by the rubber material 12 of the anti-vibration rubber 11 and the vibration is prevented from propagating to the machine base 5.

For example, when a vibration is applied due to an earthquake or the like, the hoisting machine 1 fixed to the hoisting machine base 3 is greatly shaken.
At this time, when the hoisting machine 1 moves in the horizontal direction, the hoisting machine base 3 and the spacer 16 fixed to the hoisting machine base 3 move in the horizontal direction in synchronization with the hoisting machine 1. Then, the moving force in the horizontal direction of the spacer 16 acts on the rubber material 12 via the upper seat plate 15 to deform the rubber material 12.

  When the horizontal moving force of the hoist 1 becomes larger than the set value, the spacer 16 comes into contact with the inner wall surface of the semicircular bottom of the notch 19 of the movement restricting plate 18, and the horizontal moving force of the hoist 1. Is transmitted to the machine base 5 via the spacer 16, the movement restricting plate 18, the mounting bolt 23 a, and the lower seat plate 13. Therefore, since the rubber material 12 moves in the horizontal direction in synchronization with the hoisting machine 1, the horizontal moving force of the hoisting machine 1 after the spacer 16 comes into contact with the inner wall surface of the semicircular bottom of the notch 19 is It does not act so as to deform the rubber material 12.

  When the hoisting machine 1 rotates in a horizontal plane, the rotational force of the hoisting machine 1 acts on the rubber material 12 via the spacer 16 and the upper seat plate 15 to deform the rubber material 12. When the rotational force of the hoisting machine 1 becomes larger than the set value, the spacer 16 is located at the bottom of the semicircular bottom of the notch 19 in any one of the supporting devices 10 that support the hoisting machine base 3 at three points. Contact the inner wall surface. Therefore, the rotational force of the hoisting machine 1 after the spacer 16 contacts the inner wall surface of the semicircular bottom of the notch 19 does not act so as to deform the rubber material 12.

  When the hoisting machine 1 moves in the vertical direction, the moving force of the hoisting machine 1 acts on the rubber material 12 via the spacer 16 and the upper seat plate 15 to deform the rubber material 12. When the moving force in the vertical direction of the hoisting machine 1 becomes larger than the set value, the hoisting machine base 3 or the upper seat plate 15 comes into contact with the movement restricting plate 18. Therefore, the moving force of the hoisting machine 1 after the hoisting machine base 3 or the upper seat plate 15 comes into contact with the movement restricting plate 18 does not act so as to deform the rubber material 12.

  In this manner, the support device 10 can regulate the movement of the hoist 1 in the horizontal direction, the vertical direction, and the rotation direction. Therefore, even if an exciting force such as an earthquake is applied to the hoisting machine 1, even if the hoisting machine 1 moves in the horizontal direction, the vertical direction, or rotates, the support device 10 transmits a force that excessively deforms the rubber material 12. Therefore, the amount of deformation of the rubber material 12 is suppressed, and a situation where damage or breakage is prevented is prevented. As a result, a situation in which the rubber material 12 is greatly deformed, damaged or broken and the hoist 1 falls over can be avoided.

  The support device 10 does not need to have a special structure in which the spacer bolt mounting seat is embedded in the center of the vibration-proof rubber unlike the conventional support device, and the vibration-proof rubber 11 can be realized with a simple configuration. Miniaturization and cost reduction are achieved.

  The support device 10 is erected from the axial center position of the upper seat plate 15 of the anti-vibration rubber 11 and uses a spacer 16 that is fixed to the hoisting machine base 3, so that the hoisting machine 1 is horizontally, vertically, and rotated. A movement restricting mechanism for restricting the movement of the head. Therefore, the vibration isolating mechanism and the movement restricting mechanism are coaxial, and an increase in the radial dimension of the support device 10 is suppressed, and the size can be reduced. As a result, when the support device 10 is installed in place of the existing support device that does not include the movement restriction mechanism, a situation in which the support device 10 interferes with the wall 7 of the machine room is avoided.

  In addition, since the support device 10 uses the spacer 16 fixed to the hoisting plate 15 and fixed to the hoisting machine base 3 for the movement restriction mechanism, the hoisting machine base 3 is attached to the hoisting machine base 3 in order to attach the supporting device 10 to the hoisting machine base 3. The bolt insertion holes formed in the above are only bolt insertion holes for fastening the spacer 16. Therefore, when the present support device 10 is installed in place of the existing support device that does not include the movement restriction mechanism, a bolt insertion hole formed in the hoisting machine base 3 for attaching the existing support device to the hoisting machine base 3 is provided. It is possible to simply install the support device 10. As a result, no additional drilling is required, and the installation workability of the support device 10 is improved.

  Here, by adjusting the groove width of the notch 19, that is, the diameter of the bottom of the semicircular shape, setting of the horizontal moving force in which the spacer 16 contacts the wall surface of the bottom of the notch 19 and the rotational force in the horizontal plane is set. The value can be set arbitrarily. Further, by adjusting the gap between the movement restricting plate 18 and the upper seat plate 15 and the gap between the movement restricting plate 18 and the hoisting machine base 3, the upper and lower portions where the movement restricting plate 18 contacts the upper seat plate 15 or the hoisting machine base 3. The set value of the direction moving force can be set arbitrarily.

  In the first embodiment, the three points of the hoisting machine base 3 are supported by the machine base 5 via the support device 10, but the supporting devices 10 are arranged at all three points of the hoisting machine base 3. It is not necessary to arrange the supporting device 10 at two points so that the groove direction of the notch 18 is reversed, and even if a supporting device without a movement restricting mechanism is arranged at the remaining one point, The movement in the rotational direction and the vertical direction can be restricted.

  When the hoisting machine base is rectangular, the four corners of the hoisting machine base are supported by the machine base 5 via the supporting device, but it is not necessary to use the present supporting device 10 for all the supporting devices. . For example, even if the support device 10 is arranged at two points so that the groove direction of the notch 18 is opposite, and the support device without the movement restriction mechanism is arranged at the remaining two points, the horizontal direction, the rotation direction, The movement in the vertical direction can be restricted.

Thus, the spacer 16 comes into contact with the inner wall surface of the movement restricting hole 25 of the movement restricting plate 18A. When the rotational force in the horizontal plane of the hoisting machine 1 exceeds the set value, the spacer 16 is moved by the movement restricting plate 18A in any one of the supporting devices 10A of the supporting device 10A that supports the hoisting machine base 3 at three points. It contacts the inner wall surface of the movement restricting hole 25. Further, when the moving force in the vertical direction of the hoisting machine 1 exceeds the set value, the movement restricting plate 18A comes into contact with the upper seat plate 15 or the hoisting machine base 3.
