Description

Technical Field [0001] The present invention relates to a support device for an elevator hoist machine,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support apparatus for a hoist for an elevator, and more particularly to a support apparatus for a hoist for restricting movement of a hoist during an earthquake.

In the conventional elevator hoisting machine support device, the vibration proof rubber is inserted between the base bearing and the machine beam, the vibration proof rubber upper plate and the base bearing are fixed by bolts, the vibration proof rubber lower plate and the machine beam are fixed to the bolt And a seat for mounting a stopper bolt is fixed to a bottom plate of the anti-vibration rubber by welding or the like so that it is positioned at the center of the anti-vibration rubber, and the stopper bolt penetrates through a hole formed in the base bearing, (See, for example, Patent Document 1).

In the conventional elevator hoisting machine support device, since the stopper bolt is inserted into the hole formed in the base bearing so as to be fitted in the hole, when the hoisting machine is moved in the horizontal direction, the vertical direction or the rotation direction, Or the stopper bolt abuts on the base bearing, so that the movement of the hoisting machine in the horizontal direction, the vertical direction, and the rotation direction is restricted. Thus, the vibration-proof rubber is not excessively deformed, and the damage or breakage of the vibration-proof rubber is prevented, and the turning-over of the traction machine due to breakage of the vibration-proof rubber is prevented.

[Patent Document 1] JP-A-58-74485

In the conventional elevator hoisting machine support device, the seat for mounting the stopper bolt is disposed at the center of the anti-vibration rubber, and the anti-vibration rubber structure is complicated, leading to an increase in cost.

Further, since the hole for installing the stopper bolt mounting sheet is formed at the center of the vibration-proof rubber, the diameter of the vibration-proof rubber is increased by the hole to secure the vibration-proof property equivalent to that of the vibration- In addition, as the vibration proof rubber increases, the vibration proof rubber upper and lower plates become large, and the supporting device becomes large. In addition, in the conventional support device, since the movement restricting stopper bolt is a separate component from the bolt for fixing the vibration-damping rubber upper plate to the base bearing, it is necessary to form a hole through which the stopper bolt is inserted in the base bearing.

If a conventional support device is to be installed in place of an existing support device that does not have a mechanism for restricting the movement of the traction machine in the horizontal direction, the vertical direction, and the rotation direction, Or additional hole machining is required, resulting in deterioration in installation workability.

Disclosure of the Invention The present invention has been made to solve such a problem, and it is an object of the present invention to provide a vibration isolating rubber which is fixed to an upper left seat of a vibration proof rubber so as to restrict movement of a traction machine by using a spacer connecting the vibration proof rubber and a traction base, And it is an object of the present invention to obtain a supporting device for a hoisting machine for an elevator capable of reducing the mounting hole machining to the hoisting machine base.

A supporting apparatus for an elevator hoist for an elevator according to the present invention is characterized in that a vibration damping rubber constituted by a rubber material sandwiched between an upper seat plate and a lower seat plate and arranged by placing the lower seat plate on a flange of a machine base, A cylindrical spacer whose one end is fixed to the upper seat plate so as to stand on the upper seat plate and whose other end is fixed to the base of the traction machine; And a movement regulating plate which has a regulating hole and is fixed to the lower seat plate and extends between the upper seat plate and the trailer base and is inserted and passed while the spacer is fitted in the movement regulating hole.

According to the present invention, the movement restricting hole is formed in the movement restricting plate which is fixed to the lower seat and extends between the upper seat and the hoist base, and the spacer connecting the upper seat and the hoist base is inserted into the movement restricting hole Through which the movement of the traction machine is restricted. Thus, since the vibration-proof rubber does not constitute the movement regulating mechanism, the structure of the vibration-proof rubber can be simplified, and the cost and size can be reduced.

Further, since the spacer for transmitting the vibration of the traction machine by the vibration-proof rubber also serves as a member for restricting the movement of the traction machine by abutting against the inner wall surface of the movement restricting hole, the mounting hole formed in the traction machine base, Hole only. As a result, when the present supporting device is provided in place of the supporting device having no mechanism for restricting the movement of the traction machine, the hole formed in the traction machine base for mounting the existing supporting device can be used Therefore, additional hole machining is unnecessary, and installation workability is improved. Further, since the vibration-proofing mechanism and the movement restricting mechanism are coaxial, the dimension of the support device in the radial direction can be suppressed and the size can be reduced, so that the present supporting device does not interfere with the wall of the building.

Embodiment 1

FIG. 1 is a side view showing a supporting apparatus for a hoist for an elevator according to Embodiment 1 of the present invention. FIG. 2 is a cross-sectional view taken along a direction II-II of FIG. 1 and FIG.

1 to 3, the traction machine 1 is fixed to a T-shaped traction machine base 3 and includes a main body 3 for suspending a riding car body (not shown) and a balance weight (not shown) The rope 4 is wound on a driving sheave 2.

The machine base 5 is made of H-shaped steel and is arranged in parallel and secured to the bottom 6 of the upper machine room of the hoistway 8 by anchor bolts (not shown). A T-shaped one side of the traction machine base 3 is mounted on one of the machine bases 5 and a projecting end of the other side extending from the center of the one side is mounted on the other machine base 5 It is witty. The traction machine base 3 is supported on the machine base 5 via the support device 10 at three points of the T-shaped one-side end portions and the other-side end portions.

The support device 10 includes the vibration proof rubber 11 mounted on the flange 5a of the machine base 5, the fastening means for fastening and fixing the vibration proof rubber 11 to the flange 5a, And a movement regulating plate 18 which engages with the spacer 16 and regulates the movement of the traction machine 1 due to an earthquake or the like.

The vibration proof rubber 11 has a rubber material 12 formed into a cylindrical shape, a lower flat plate 13 of a rectangular flat plate fixed to the lower surface of the rubber material 12, And an upper seat plate 15 in the form of a circular plate. A mounting through hole 14 is formed at four corners of the lower seat 13. The spacer 16 is formed in a cylindrical shape and fixed to the upper seat 15 by welding or the like so as to be coaxial with the axial center of the rubber material 12. The female screw portion 17 is formed at the axial center of the spacer 16 with the screw hole direction as the axial direction.

The movement regulating plate 18 is formed in a rectangular flat plate shape and has a notch 19 as a movement regulating hole. The notch 19 has a groove width larger than the diameter of the spacer 16 and is formed into a hole shape having one end opened at the center of one side edge of the movement regulating plate 18 and a semi- have. In addition, the mounting through-holes 20 are formed in the edge portions of the side opposite to the bottom of the notch 19 of the movement regulating plate 18 in the longitudinal direction of the sides thereof (separated from each other).

The clip member 21 is formed in an L shape having a base portion 21a and a fitting portion 21b extending from one side in the thickness direction of the base portion 21a and the through hole 22 is formed in the base portion 21a in the thickness direction. 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 vibration proof rubber 11 is placed on the flange 5a of the machine base 5 and the base portion 21a of the clip member 21 is placed on the lower surface of the four corners of the lower seat 13, The mounting bolts 23a and 23b are inserted into the through hole 22 formed in the base portion 21a of the clip member 21 and the lower seat 13, And is fastened to the machine base 5 by fastening the mounting bolts 23a and 23b and the nut 24 to each other. The two mounting bolts 23a extend parallel to each other so as to face the spacer 16 through the outer side of the upper seat 15 and the shaft portion.

The movement regulating plate 18 passes the mounting bolt 23a through the through hole 20 so that the center of the bottom of the semicircular shape of the notch 19 is aligned with the axial center of the vibration proof rubber 11, A pair of nuts 24 screwed to the shaft portion of the mounting bolt 23a are fastened to the two mounting bolts 23a so as to interpose the movement regulating plate 18 therebetween. Thereby, the spacer 16 is accommodated in the notch 19 with its axial center coinciding with the center of the bottom of the semicircular notch 19. Further, a mounting bolt (not shown) is passed through a through hole (not shown) formed in the traction machine base 3 and is fastened to the female threaded portion 17 so that the traction machine base 3 is rotated And is supported by the machine base 5.

The movement regulating plate 18 of the supporting apparatus 10 for supporting both ends of the T-shaped one side of the traction machine base 3 is arranged so that the depth direction of the U- , And the opening of the notch 19 is arranged so as to face the projecting end side of the other T-shaped side of the traction machine base 3 . The movement regulating plate 18 of the supporting apparatus 10 which supports the extended portion of the other T-shaped side of the traction machine base 3 is arranged so that the depth direction of the U-shaped groove of the notch 19 is aligned with the traction machine base 3 And the opening of the notch 19 is arranged so as to face the T-shaped one side of the traction machine base 3.

In addition, the through hole 20 is formed by a long hole connecting both ends of two parallel lines with a semicircle, and the movement regulating plate 18 is arranged such that the axis of the spacer 16 is located at the center of the bottom of the semicircular shape of the notch 19 And is fixed to the mounting bolt 23a.

Next, the operation of the support apparatus 10 will be described.

First, the vibration generated in the traction machine 1 is transmitted to the vibration proof rubber 11 via the traction machine base 3 and the spacer 16. [ Then, the vibration is absorbed by the rubber material 12 of the vibration-proof rubber 11, so that the vibration is prevented from propagating to the machine base 5.

For example, when excited by an earthquake or the like, the member above the supporting device 10, that is, the traction machine 1 fixed to the traction machine base 3 largely shakes.

At this time, when the traction machine 1 moves in the horizontal direction, the traction machine base 3 and the spacer 16 fixed to the traction machine base 3 move in synchronism with the traction machine 1 in the horizontal direction. The horizontal moving force of the spacer 16 acts on the rubber material 12 through the upper seat 15 to deform the rubber material 12. [

When the horizontal moving force of the traction machine 1 becomes larger than the set value, the spacer 16 comes into contact with the inner wall surface of the bottom of the semicircular shape of the notch 19 of the movement regulating plate 18, The moving force in the horizontal direction is transmitted to the machine base 5 through the spacer 16, the movement regulating plate 18, the mounting bolt 23a and the lower seat plate 13. [ Therefore, the rubber material 12 moves in the horizontal direction in synchronization with the traction machine 1, so that the horizontal movement force of the traction machine 1 after the spacer 16 abuts the inner wall surface of the semi- Does not act to deform the rubber material 12.

When the traction machine 1 is rotated in the horizontal plane, the rotational force of the traction machine 1 acts on the rubber material 12 through the spacer 16 and the upper seat 15, ). When the rotational force of the traction machine 1 is larger than the set value, the spacers 16 are notched in the support device 10 of the support device 10 supporting the traction machine base 3 at three points, The inner wall surface of the bottom of the semicircular shape of FIG. Thus, the rotational force of the traction machine 1 after the spacer 16 abuts against the inner wall surface of the semicircular bottom of the notch 19 does not act to deform the rubber material 12. [

When the traction machine 1 moves in the vertical direction, the moving force of the traction machine 1 acts on the rubber material 12 through the spacer 16 and the upper seat plate 15 to deform the rubber material 12 . When the moving force of the traction machine 1 in the up and down direction becomes larger than the set value, the traction machine base 3 or the upper seat plate 15 is brought into contact with the movement regulating plate 18. Therefore, the moving force of the traction machine 1 after the traction machine base 3 or the upper seat plate 15 is brought into contact with the movement regulating plate 18 does not act to deform the rubber material 12.

Thus, the support apparatus 10 can regulate the movement of the traction machine 1 in the horizontal direction, the vertical direction, and the rotation direction. Thus, even if an excitation force such as an earthquake is applied to the hoisting machine 1 and the hoisting machine 1 moves or rotates in the horizontal direction or the vertical direction, the force of the support device 10 deforming the rubber material 12 excessively So that the deformation amount of the rubber material 12 is suppressed, thereby preventing the occurrence of damage or breakage. As a result, the situation in which the rubber material 12 is largely deformed, damaged or broken and the winding machine 1 is conducted is avoided in advance.

The support device 10 does not need to have a special structure such as a conventional support device in which the spacer bolt attachment sheet is buried in the center of the vibration proof rubber and the vibration proof rubber 11 has a simple structure And it is possible to achieve downsizing and cost reduction.

The support device 10 is provided upright from the axial center position of the upper seat plate 15 of the vibration proof rubber 11 and is provided with a spacer 16 fixed to the traction machine base 3 so that the horizontal direction of the traction machine 1, Downward direction, and the rotation direction of the movable member. Thus, the dust-proof mechanism and the movement restricting mechanism are coaxial, and the increase in the dimension in the radial direction of the support device 10 is suppressed, thereby making it possible to achieve miniaturization. As a result, when the present supporting device 10 is installed in place of the existing supporting device which is not provided with the movement restricting mechanism, there is no situation in which the supporting device 10 interferes with the wall of the machine room .

Since the supporting device 10 uses the spacer 16 fixed to the upper seat 15 and fixed to the traction machine base 3 as the movement regulating mechanism, the supporting device 10 can be mounted on the traction machine base 3 The bolt insertion hole formed in the hoisting machine base 3 for mounting is only a bolt insertion hole for fastening the spacer 16. [ Therefore, when the present supporting device 10 is installed in place of the existing supporting device not provided with the movement restricting mechanism, the existing supporting device is formed on the traction machine base 3 to be mounted on the traction machine base 3 The support device 10 can be easily installed using the bolt insertion hole. As a result, additional hole machining is not necessary, and mounting workability of the support apparatus 10 is improved.

By adjusting the width of the groove of the notch 19, that is, the diameter of the bottom of the semicircular shape, the horizontal movement force of the spacer 16 against the wall surface of the bottom of the notch 19 and the set value Can be arbitrarily set. By regulating the clearance between the movement regulating plate 18 and the upper seat 15 and the clearance between the movement regulating plate 18 and the trailer base 3 the movement regulating plate 18 can be moved to the upper seat 15 or It is possible to arbitrarily set a set value of the upward and downward movement force abutting the traction machine base 3.

In the first embodiment, three points of the traction machine base 3 are supported by the machine base 5 via the supporting device 10. However, in all of the three points of the traction machine base 3, It is not necessary to arrange the support device 10 at two points so that the direction of the groove of the notch 19 is in the reverse direction and the support device not having the movement regulating mechanism at one remaining point , The horizontal direction, the rotation direction, and the vertical direction.

When the traction machine base is rectangular, the four corners of the traction machine base are supported by the machine base 5 via the support device. However, it is not necessary to use the present support device 10 for all of the support devices. For example, even if the support device 10 is disposed at two points such that the groove of the notch 19 is in the reverse direction and a supporting device not provided with the movement restricting mechanism is disposed at the remaining two points, , The vertical movement can be regulated.
