Description

[Detailed Description of the Invention] The present invention relates to a machine base mounting device on which an elevator hoist is mounted.

Generally, as shown in FIGS. 1 and 2, an elevator has a hoist 11 equipped with a sheave 12, and a rope 13 attached to the sheave 12.
is hung.

A car 14 is attached to one end of the rope 13, and a counterweight 15 is attached to the other end, and the car 14 is moved up and down by the frictional force between the sheave 12 and the rope 13.

In order to maintain the distance between the car 14 and the counterweight 15 at a predetermined value, the solenoid car 16 is attached to the machine beam 17 by a shaft support 20 to which a shaft 19 is attached.

Here, the car and counterweight are usually installed interchangeably with those shown in FIG.

During elevator operation, vibrations are generated from a series of mechanical devices, and in order to prevent the vibrations from being transmitted to the building via the machine beam 17, a vibration isolating rubber 33 is generally inserted between the hoisting machine base 18 and the machine beam 17. The connection between the shaft support 20 of the solace vehicle 16 and the machine beam 17 was directly fixed with bolts 21.

In recent years, due to the structure of the building and the arrangement conditions of living rooms, there have been problems with vibrations transmitted from the solace car 16, ease of placement of the solace car 16 of the hoisting machine 11 as it approaches the machine room wall, and Improvements in ease of attachment and detachment and maintenance are required, and for this purpose, machine beam 17 and building stiffness 3 are installed as shown in Figure 3.
1, a vibration isolating rubber 32 is attached via a base 34.

Although this method satisfactorily achieves the purpose of blocking vibrations, it requires a technically advanced design or construction method for attaching the building stiffness 31 and the machine beam 17, and also requires maintenance. However, it is very difficult to replace the vibration isolating rubber 32, and the cost is also high.

On the other hand, a problem with conventional elevators is the miniaturization of the hoisting machine 11 placed in the machine room.

That is, the machine room is generally provided in a relatively small room.

In such a case, the wall of the hoistway provided below the machine room and the machine room wall should be architecturally (in terms of strength) straight - and the hoisting machine 11 should be installed extremely close to the machine room wall. There are many.

However, in the conventional type, a vibration isolating rubber 32 is interposed between the solace wheel 16 attached to the machine beam 17 of the hoisting machine 11 and the machine room wall, and the space for the vibration isolating rubber 32 and its installation is
Sorase Car 16 could not approach the machine room.

Here, as shown in FIG. 1, the car 14 and the counterweight 15 were attached to the end of the rope 13 as shown, but this is generally the same as the method of replacing the car 14 and the counterweight 15 in reverse. This is a well-known technique that has been used.

Especially in buildings for small and medium-sized buildings, the elevator capacity is small and the hoistway and machine room of the building are small. Reducing the spacing is extremely advantageous in terms of effective use of the hoistway and machine room, and has been desired.

Therefore, in the conventional type, the vibration isolating rubber 32 is provided between the solenoid wheel 16 and the machine room wall, and it has not been possible to bring it close to the machine room wall.

Further, the conventional solenoid wheel 16 is attached to the lower surface of the machine beam 17, and a special mounting hole is provided at least on the floor of the machine room below the solenoid wheel 16 as a mounting space for the solenoid wheel 16 to facilitate attachment and detachment.

Sorase car 16 is relatively heavy and machine beam 1
Since it is installed on the underside of 7, it is quite difficult to access in case replacement is required during new installation work or maintenance.In addition, it is located on the ceiling at the top of the hoistway, and is located on both the machine room and the hoistway side. must be used as a mounting and dismounting space, and work at heights on the hoistway side is extremely dangerous, requiring full-scale scaffolding and resulting in large-scale construction work.

This takes time and has the drawbacks of poor delivery times and maintenance services (repairs), as well as high economic costs.

This invention was made to eliminate the above points,
It is inexpensive and easy to install on the building side, and in particular, it does not matter if the machine room walls are close together, and the hoisting machine can be installed and removed in the machine room.It is easy to maintain. It's about doing it at the same time.

An embodiment of the present invention will be described below.

In FIGS. 4 and 5, the hoisting machine 11, the vehicle support stand 20 made of channel material, etc., and the support stand 22 made of H-shaped steel etc. are attached to the machine base 23 by bolts (not shown).
is firmly fixed.

The solace wheel 16 is fixed to the solace wheel support stand 20 by a shaft 19, and its movement in the axial direction is restricted by a key plate 244. The shaft 19 and the solace wheel 16 are rotatably connected by a bearing (not shown). There is.

The vibration isolating rubber 27 is arranged between the vehicle support stand 20 and the support stand 22 and the machine beam 17, and is fixed by bolts 25 and 26, respectively.

By combining the vibration isolating rubber 27 with a pre-designed material having a vibration damping effect, it is possible to prevent vibrations generated from the mechanical parts from being transmitted to the machine beam 17.

In addition, since the elevator is driven by the frictional force between the sheave 12 and the rope 13, it is necessary that the rope wrapping angle of the sheave 12 is within a permissible value.
The height H of 3 is selected so that the required wrapping angle can be obtained.

According to the above configuration, the machine beam 17 and the machine base 2
Since the solace wheel support stand 20 and the vibration isolating rubber 27 are stacked in series between the two spaces, the hoisting machine 11 can be installed even if the machine room walls approach each other as described above.

In addition, since the solenoid wheel 16 is raised above the machine beam 17, the outer ring portion of the solenoid wheel 16 does not come into contact with the machine room floor, and there is no need to provide a hole in the machine room floor.

As shown in FIG. 5, this not only makes it possible to safely and easily attach and detach the solenoid car 16 within the machine room, but also has the secondary effect of preventing machine room noise from propagating through the air toward the hoistway.

As mentioned above, the present invention is an inexpensive and easy construction method for buildings (
It has many effects, such as being able to improve the installation (no need for wall access or floor holes), and making it easier to install and remove when installing a new Sorace car or during maintenance (replacement after a long period of time).
