Description

[Detailed description of the invention] This invention relates to an installation device for an elevator display machine.

First, a conventional installation device for a performance machine will be explained with reference to FIG.

In the figure, 1 is the machine room floor, 1a is a building frame consisting of a load receiving part with strength members such as building beams installed at the bottom of the machine room floor 1, and 1b is after the installation of elevator equipment (not shown) is completed. Cinder concrete for finishing the machine room floor 1, 2 is a support installed on the building frame 1a of the machine room floor 1, 3 is a machine stand built on this, 4 is a support on the upper blade of the machine stand 3. The attached vibration isolator 5 made of anti-vibration rubber is a hoisting machine stand supported by the vibration isolator 4, to which a hoisting machine 6 and a solace wheel 7 are attached.

That is, although vibrations generated from the hoisting machine 6 and the soaring wheel 7 are transmitted to the hoisting machine stand 5, the vibration isolator 4 reduces the transmission to the machine stand 3.

However, some vibrations are not completely damped and are transmitted to the machine table 3.

Therefore, the support body 2 prevents the machine stand 3 from coming into direct contact with the machine room floor 1 and the cinder conc'J-) 1b, thereby preventing the machine room floor 1 from vibrating due to the vibrations transmitted to the machine stand 3. are doing.

However, in the case of this method, the sounding machine 6 from the machine room floor 1
This increases the height of the machine room, requiring a large effective height of the machine room, and also increases the center of gravity of the hoist 6, which causes instability and increases the risk of earthquakes.

This invention solves the above-mentioned drawbacks and aims to provide an installation device for an elevator hoisting machine in which the hoisting machine can be installed at a low height without impairing the vibration-proofing effect.

An embodiment of this invention will be described below with reference to FIGS. 2 and 3.

In the figure, the same symbols as in FIG. 1 indicate corresponding parts, 8 is a storage box for the vibration isolator 4 provided in the building frame 1a, 8a is the bottom of this, and 9 is the vibration isolator 4 fastened to the bottom 8a. It is a fastener that has been

That is, the storage box 8 is placed on the building frame 1a of the machine room floor 1, the vibration isolator 4 is provided therein, and the upper part of the vibration isolator 4 allows
A machine stand 3 to which a hoist 6 and a soaring wheel 7 are directly fixed is supported.

By placing the vibration isolator 4 in the storage box 8, it is possible to prevent the cinder concrete 1b which is applied after installation from adhering to the vibration damping body 4 and thereby impairing the vibration damping effect.

Also, due to the height of the vibration isolator 4 itself, the machine stand 3 is placed on the machine room floor 1.
And it will float above the cinder concrete 1b.

As a result, vibrations generated by the hoisting machine 6 and the soaring wheel 7 are transmitted to the machine stand 3, but are attenuated by the action of the vibration isolator 4.

Further, since the load and vibration on the vibration isolator 4 are directly transmitted to the building frame 1a of the machine room floor 1, it is possible to prevent the machine room floor 1 from vibrating.

However, since the function of the hoisting machine stand 5 is added to the machine stand 3, the installation position of the hoisting machine 6 can be lowered.

Therefore, the effective height of the machine room can be reduced, and earthquake resistance is also improved.

Furthermore, since the number of parts is reduced compared to the conventional method, it is also possible to lower manufacturing costs.

4 and 5 show other embodiments of this invention, in which the same reference numerals as in FIGS. 2 and 3 indicate corresponding parts, and 4 is directly fixed to the bottom 8a of the storage box 8. It is a vibration isolator made of rubber.

That is, in this embodiment as well, the storage box 8 is provided with the vibration isolator 4, so detailed explanation will be omitted, but the second and third
It is clear that the same effect as in the illustrated embodiment can be obtained.

6 and 7 also show an embodiment of this invention. In the figures, the same reference numerals as in FIGS. 2 and 3 indicate corresponding parts, and 8b is provided at the upper edge of the storage box 8. The protrusions 4a, which protrude in the direction and are arranged apart from each other, are blocking bodies which are arranged outside the storage box 8 without contacting the top plate 4b of the vibration isolator 4 and are bent downward. 8b are arranged with a gap between them.

That is, in this embodiment as well, the storage box 8 is provided with the vibration isolator 4, so although a detailed explanation will be omitted, it is clear that the same effect as in the embodiments shown in FIGS. 2 and 3 can be obtained.

Further, in this embodiment, when the hoisting machine 6 or the like is displaced in the horizontal direction due to an earthquake or the like, the blocking body 4a collides with the protrusion 8a to prevent excessive displacement.

For this reason, it is possible to prevent the occurrence of abnormalities in the broadcasting device 6 and the like during an earthquake.

As explained above, the idea was to place a storage box on the building frame and support the machine platform through a vibration isolator placed inside the box, so the cinder concrete would impair the vibration isolation function of the vibration isolator. To provide an installation device for an elevator hoisting machine that is inexpensive by reducing the number of parts and reducing the number of parts. It is.
