Description

[Detailed Description of the Invention] This invention relates to a vibration isolating device for an elevator hoisting machine.

First, a conventional vibration isolating device for an elevator hoisting machine will be explained with reference to FIGS. 1 and 2.

In the figure, 1 is the machine room, 1a is the floor of this machine room, 2 is a support stand made of section steel installed on the floor 1a side, and 3 is a sink with the support stand 2 partially buried in the floor 1a side. concrete,
4 is a mounting base fixed on the support base 2; 5 is a vibration isolator made of anti-vibration rubber mounted on this; 6 is a mounting bracket whose lower surface is attached to the upper surface of the vibration isolator 5; 7 is a machine stand whose both ends are fixed on the mounting brackets 6, 8 is a vibration-proof rubber mounted on the top surface of this, 9 is a hoisting machine stand supported by the vibration-proof rubber 8, and 10 is a machine stand supported by the vibration-proof rubber 8. A hoisting machine mounted on the hoisting machine 11, a deflection wheel pivotably mounted on the lower part of the hoisting machine stand 9, 12
is the main rope wrapped around the hoist 10 and the deflection wheel 11,
13 is a hook provided on the ceiling of machine room 1.

That is, the hoist 10 is disposed in the machine room 1 via the vibration isolator 5 and the vibration isolator 8, and is supported with double vibration isolation.

This prevents vibrations and noise generated from the hoisting machine 10 from being transmitted to the machine room 1, thereby keeping the building in which the machine room 1 is installed quiet.

However, since each member such as the vibration isolator 5 and the machine stand 7 is stacked on top of each other, the position of the hoist 10 becomes high, resulting in a lack of stability. This has the disadvantage that the reduced amount of water becomes a hindrance to installation and maintenance work, resulting in unexpected costs.

This invention solves the above-mentioned drawbacks and aims to provide a vibration isolating device for an elevator hoisting machine that provides double vibration isolation and can be easily installed.

An embodiment of this invention will be described below with reference to FIGS. 3 and 4.

In the figure, the same reference numerals as those in FIGS. 1 and 2 indicate corresponding parts, and 2 is a support made of steel material in the shape of an angle iron, and is arranged so that one side 2a of the angle shape is overlapped with the surface of the floor 1a, and the other side 2b The upper edge portion is bent in the direction of one piece 2a, and a portion thereof is provided with an upright portion 2c.

5 is fixed to the upper surface of one side 2a of the support base 2, and the upright part 2c
6 is a mounting bracket whose lower surface is attached to the upper surface of the vibration isolator, and 7 is a vibration isolator which is attached to the upper surface of the mounting bracket 6 and whose end is fitted into the upright portion 2c. It is a machine stand.

That is, since the vibration isolator 5 is fixed to the upper surface of one side 2a of the support base 2 fixed to the floor 1a surface by an anchor bolt, the vibration isolator 5 can be provided at a position lower than the floor 1a surface.

Therefore, the positions of structures such as the machine stand 7 and the hoisting machine stand 9 can be lowered, and the installation height of the hoisting machine 10 can be lowered.

This provides stability for the hoist 10, and allows the hoist 10 to be installed without any problem even in the machine room 1 with a low ceiling height.

Further, the end of the machine stand 7 is disposed on the upright part 2c, and excessive displacement of the machine stand 10 due to an earthquake or the like is prevented by the upright part 2C and the end face of the other side 2b of the support stand 2 opposite thereto.

Therefore, the overdisplacement prevention effect can be obtained at low cost without requiring any additional members.

As explained above, in this invention, the lower vibration isolator of the device that provides double anti-vibration support for the hoisting machine is attached to the upper part of the support stand, which is shaped like angle iron and is placed so that one side overlaps the floor of the machine room. - Since it is provided on the upper surface of the side, the position of a structure such as a machine stand supported by the vibration isolator can be lowered, and the installation height of the hoist can be lowered.

This improves the stability of the hoist,
Furthermore, the present invention provides a vibration isolating device for an elevator hoisting machine that allows the hoisting machine to be easily installed even in a machine room with a low ceiling.
