Description

DETAILED DESCRIPTION OF THE INVENTION [Techniques of the Invention (Field 4j]) This invention relates to an elevator hoisting device in which an unwinding machine is provided in a machine room provided on one side of a hoistway.

[Prior art]

Conventionally, as shown in Japanese Utility Model Application Publication No. 52-72270, etc., a machine stand was installed on the floor of a machine room provided on one side of the hoistway, and an unwinding machine was installed on this machine stand. A hoisting Wc arrangement for an elevator is known.

Such a conventional hoisting device will be explained with reference to FIGS. 1 to 3. In these figures, 1 is a hoistway, 2 is a machine room provided on the first floor on one side of the hoistway and opens to the hoistway 1, 3 is a machine stand installed on the floor 2a of the machine room 2, 4 ha ha search 3
An unwinding machine installed above, 5 a cage installed in the hoistway 1,
6 is a barb 1110.7 provided at the upper end of the hoistway 1.
The main rope 7 is cut off at one end to make the car 5 earthen, and the main rope 7 is let out from the drum 4a to lower the car 5.

In addition, 8 is a fixing plate formed at the lower end of the hoistway 1 and is in contact with the side surface of the machine chamber 4 of the pit part 1a, and 9 is a fixing plate for fixing the fixing plate 8 to the side surface of the pit part 1a. Anchor bolt OJ: A fastener consisting of a nut, etc., 10 is a fixing plate 8
A reinforcing plate 11 is welded to the upper end surface 11tll, and 11 is an upper end bent portion 8a protruding from the fixed plate 8 toward the hoistway 1 side, and a bolt for fixing the reinforcing plate 10 and the end of the machine platform 3 on the hoistway 1 side. It is a conclusion consisting of nanoto. Note that (the reed probe 3 is also fixed to the floor 2a of the machine room 2 by an appropriate member not shown).

The elevator hoisting device constructed as described above has the width dimension A of the machine platform 3 and the fixed plate 8 (see figure fjS3), and the width dimension A 2 between these fasteners 11 (see figure 3).
It is necessary to have high precision, which takes time and effort to manufacture.In addition, the side surface of the pit portion 1a, which the fixing plate 8 comes into contact with, is generally a concrete wall surface and is not smooth (as shown in Figure fjs4). Since the area of the fixing plate 8 is large, the position of the fixing plate 8 is determined by the most convex part of the side surface of the pit part 1a.
A gap is created between the bit part 1a and the vicinity of the anchor bolt insertion part 9 when fastening the fixing plate 8, making it impossible to stably fix the fixing plate 8, and a large moment is generated in the anchor bolt, causing the anchor bolt to break. , there was a drawback that the car 5 might fall.

[Summary of the invention]

This invention is an attempt to solve the above-mentioned conventional drawbacks, and by dividing the fixed plate into a plurality of parts in the width direction and fixing these to the side surface of the machine room of the hoistway and the machine stand, respectively, The purpose of the present invention is to provide an elevator hoisting device in which the machine base and fixing plate are easy to manufacture and inexpensive, and the fixing plate can be stably fixed to the side of the hoistway such as a bit part, making it highly safe. .

[Embodiment of the Invention] An embodiment of the invention will be described below with reference to FIGS. 5 and 6.

From Figures 5 and 6, and Figure 1! The same reference numerals as in the figures up to Figure 4 indicate the same or equivalent parts, and 81°8□ is the left side divided in the width direction for the left beam 31 of the machine stand 3 and the right heel 3□.
This is a right fixed version, and the left and right fixing @8□82 are each independently fastened to the side of the bit part 1a of the hoistway 1 with a plurality of fastenings of 9.9, and the above-mentioned left , is fastened to the right beam 31, 3□.

Also, when tightening, insert the bolt in 11.11 on the left.

The holes of the 6 beams 3032 are long in the longitudinal direction of the fixing plate 8. ．． Even if 82 is at a different position relative to lj3, 3□ in the longitudinal direction, it can be fastened.

In the example implanted as described above, the fixing plate 8. ．．
Since the area of 8□ is smaller than the conventional fixing plate, it can be fastened to the side of the bit part 1a with almost no gap (9), and the moment generated in the anchor bolt of the fastener 9 is small, so Pit part 1a ensuring stability
It can be fixed to the side, eliminating the risk of the anchor bolt breaking and the car falling. In addition, the fixed plate 8□8
□ is smaller and lighter, improving the workability of installation and transportation, and the machine stand 3 and fixing plate 8. ．． Since high precision is not required due to the width dimension of 82, these can be easily manufactured, and therefore, inexpensive hoisting devices and elevators can be obtained.

〔Effect of the invention〕

As explained above, the present invention allows the fixing plate to be
The fixing plates were divided into several parts and each fixed plate was fixed to the side of the hoistway and to the end of the hoistway side of the machine platform, so it was possible to securely fasten the fixing plate to the side of the hoistway, and these anchor bolts There is no risk of damage to the machine, improving safety, and high precision is not required for the machine platform and fixing plate, making the fixing plate smaller and lighter. It has the advantage that it can be provided at a low price.
