Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) This invention relates to an improvement in a hoisting machine for a basement type elevator.

(Prior art) Conventionally, a machine room was provided next to the product exit path where cars were raised and lowered.
A basement type elevator is known in which a hoisting machine for lifting a car is installed in the machine room. For example, as shown in FIG. 7, this basement type elevator has a side wall 1A.

A wall 1 is formed from the upper wall 1B and the upper wall 1C.

An intermediate wall 1D is provided between the side walls 1A and 1B. Further, a horizontal wall 1E extending in the horizontal direction is integrated with the side wall 1Δ and the intermediate wall 1D.

A top beam 3 extending horizontally is integrally provided on the side walls 1A and 1B below the upper wall 1C. Said intermediate f! The upper part of 1io is fixed to the lower part of the top beam 3.

The space formed by the side wall IB, the width wall 1D, and the top beam 3 is a hoistway 5, and the car 7 and the counterweight 9 are lifted and lowered in the direction of moving away from each other in the hoistway 5. . Also, side wall 1△.

A space formed by the intermediate wall ID, the horizontal wall 1F, and the top beam 3 is a machine room 11.

A sheave beam 15 is provided above the top beam 3 with a vibration isolating rubber 13 interposed therebetween.
5, a plurality of deflection sheaves 17°19.21.23 are arranged. Further, a beam 25 is fixed on the horizontal wall 1E in the machine room 11 with an anchor bolt 27, and a hoist R31 is arranged on the beam 25 via a vibration isolating rubber 29.

The main lobe 33 is connected to the spiers 17, 19.21.
．． 23 and the main sheave 31 provided on the hoist 1131. A, one end of the main row 133 is connected to the car 7, and the other end of the main row 133 is connected to the counterweight 9.

With the above configuration, the hoisting 11 of the basement type elevator
31 is installed on the horizontal wall 1F via the beam 25, and the horizontal wall 1E supports the total weight of the car 7 and the weight of the counterweight 9, so the strength of the horizontal wall 1E is very necessary. In addition, there were drawbacks such as the need for a beam 25 on which the hoist 31 was installed.

In order to eliminate these drawbacks, for example,
As seen in Publication No. 1369, top beam 3
In recent years, a method has been adopted in which the hoisting device 11131 is attached directly to the vehicle in a suspended manner. That is, as shown in FIG. 8, the top beam 3 is connected to the side walls IA, 1B via vibration-proof rubber 35, 37, 39.

It is attached to the intermediate wall 1D.

In the machine room 11, a hoist 31 is attached to the lower surface of the top beam 3 in a suspended manner with bolts 41. Deflecting sheaves 17, 19, and 23 are installed directly on the top surface of the top beam 3, and the main rope 33 is wound around the main sheave 31A of the hoisting 1131 and the forward sheaves 17, 19, 23, so that the main rope 33 is One end is connected to the car 7, and the other end of the main loaf 33 is connected to the counterweight 9.

(Problem to be Solved by the Invention) By the way, according to the above-mentioned conventional hoisting machine 31 installed in a suspended type, the strength of the horizontal wall 1F is not required, and the beam 2
5 is also unnecessary, but on the other hand, the hoisting machine 3
1 on the top beam 3, as shown in FIG.
put on top.

In addition, a chain block 45 and a merging wire 47 are attached to a hook 43 fixed to the upper wall 1C, and a hoisting l1
31 to pull up the hoist 31. When the hoist 31 is pulled up in this state, the mounting surface 31C of the mounting base 31B to the top beam 3 makes a considerable angle to the top beam 3 and rises without being horizontal.
It is very difficult to align the mounting hole 31D of the mounting base 31B to which the bolt 41 is attached with the mounting hole 3A of the top beam 3.

Further, since the hoisting machine 31 normally has a weight of nearly 1 to 3 tons, the rotation of the hoisting machine 31 must be significantly corrected while the hoisting machine 31 is hoisted so that the mounting surface 31C is parallel to the top beam 3. The problem was that the work was difficult and dangerous.

The purpose of this invention is to improve the above-mentioned problems by making the top beam and the mounting base of the hoisting machine horizontal with a slight modification when hoisting the hoisting machine, and to make the mounting work easier and safer. It is possible to provide shape elevator hoist.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention provides a structure in which the total weight of the car and the weight of the counterweight are placed at the top of the hoistway where the car and the counterweight are raised and lowered. A top beam is provided to support the
In a basement type elevator in which a hoisting machine that lifts a Moeki car is attached to the top beam in a suspended manner, this mounting mount is installed on the lower side of the mount of the hoisting machine on which the hoisting machine is attached to the top beam. A hoisting machine for a basement-type elevator was constructed by providing a base having a surface substantially parallel to the surface for attaching the top beam to the top beam.

(Function) By adopting the hoisting machine of the basement type elevator of the present invention, when the hoisting machine is attached to the top base, the mounting base of the hoisting machine has a surface that is almost parallel to the mounting surface to the top beam. Since the base is provided on the top of the hoist itself, when this base is mounted on a horizontal wall, the mounting surface of the mounting base of the hoist will be approximately horizontal with respect to the lower surface of the top beam. By pulling up the hoist in this state,
The hoist can be easily and safely attached to the top beam with only minor positional adjustments.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

Fig. 1 is a front view of a basement type elevator hoisting machine according to the present invention, Fig. 2 is a view taken along the line ■-■ in Fig. 1, and Fig. 3 is a basement type elevator hoisting machine. Fig. 4 is a front view of the installation state in which the hoist is installed in the basement type elevator.

1 and 2, a hoisting machine 49 is used instead of the conventional hoisting machine 31, and the same parts as those used in explaining the prior art in FIGS. 3 and 4 are given the same reference numerals. Since the configuration other than the state in which the hoisting machine 49 is attached is the same as that of the prior art, detailed explanation will be omitted.

First, in FIGS. 1 and 2, when the mounting base 49A of the hoisting machine 49 to the top beam 3 is placed on the upper side, the base 51 is attached to the hoisting machine 49 with bolts 53 below the mounting base 49A. It is provided in a removable manner. The lower surface 51A of the base 51 is substantially parallel to the mounting surface 49B of the mounting base 49A to the top beam 3, and the hoist 4 is mounted on the horizontal wall 1E.
9, as shown in Figure 3, the mounting surface 4
9B is almost parallel to the top beam 3.

In this state, if the hoist 149 is pulled up using the chain block 45, the mounting surface 49B of the hoist 49 will be lifted (almost parallel to the top beam 3), so it can be easily and safely installed with only a slight position adjustment. By aligning the hole 49C with the mounting base 3A of the top beam 3 and further fastening with bolts 41, the installed state as shown in FIG. 4 can be obtained.

Therefore, it is possible to eliminate the disadvantage of the dangerous and difficult operation of having to make a large rotational correction during lifting, which is the case with the prior art. Furthermore, if the base 51 becomes an obstacle when inspecting the hoisting machine 49 after it has been fixed in a suspended manner, by removing the bolts 53 and removing the base 51, inspection of the hoisting machine 49 can be carried out smoothly. can be done.

5 and 6 show other embodiments of the hoist. Figure 5 is a front view of the winding 1155, and Figure 6 is the front view of the winding 1155.
It is an arrow view along the Vl-Vl line in a figure.

5 and 6, in the hoisting machine 55, a base portion 55D having a surface 55E that is horizontal to the mounting surface 55B of the mounting base 55A having the mounting hole 55C to the top beam 3 is integrally attached to the hoisting machine 55. It is molded. Moreover, when the base portion 55D of the hoisting machine 55 is placed on the horizontal wall 1E, the mounting surface 55B of the top beam 3 and the hoisting machine 155 is Machine 4
Like the base 51 of No. 9, it is configured to be substantially horizontal, so that the same hoisting machine 55 as described above can be installed on the top beam 3 easily and safely.

[Effects of the Invention] As can be understood from the description of the embodiments above, according to the hoisting machine for a basement type elevator of the present invention, the hoisting machine can be easily and safely installed on the top beam. Can be done.
