Description

[Detailed Description of the Invention] This invention relates to an improvement of an elevator hoisting machine device.

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

In the figure, 1 is the floor of the elevator machine room, 2 is the machine stand installed on top of this, 3 is the vibration isolator made of anti-vibration rubber attached to the machine stand 2, and 4 is the hoisting machine. A stand 4a made of channel steel is provided at the bottom and supported by a vibration isolator 3.

5 is the base 5 attached to the top surface of the machine table 2 by bolts and nuts 5a.
5c is a blocking portion of the blocking device 5, which is a bolt loosely inserted into a hole provided in the lower flange of the base 4a and screwed into the base 5b.

That is, the hoisting machine 4 is provided with anti-vibration support by the vibration isolator 3 and installed so that its vibrations are not transmitted to the floor 1.

Furthermore, when the hoisting machine 4 is horizontally vibrated due to an earthquake or the like, the seismic insulator 3 bends abnormally.
The structure is such that over-displacement of the hoisting machine 4 is prevented and overturning is prevented.

However, since the platform 4a has an insertion hole for the blocking part 5c and the machine platform 2 has an insertion hole for the bolt 5a, there is a disadvantage that the strength of the machine platform 2 is reduced, and drilling for heavy objects is complicated. There was a drawback that it required a lot of processing.

This invention solves the above-mentioned drawbacks and aims to provide an elevator hoisting machine device in which overdisplacement is prevented by a blocking piece that can be easily constructed.

An embodiment of this invention will be described below with reference to FIGS. 3 to 5.

In the figure, the same reference numerals as in FIGS. 1 and 2 indicate corresponding parts, and 4b is a retaining part formed in the recess of the table 4a, and is fixed by welding in the recess and in this recess and arranged vertically. It is formed by a partition plate-shaped plate body 4c.

6 is a mounting plate fixed to the side of the machine table 2 by welding;
Reference numeral 5 denotes a blocking piece, the lower part of which is disposed facing the mounting plate 6, in which a long hole 5d is provided in the horizontal direction, and the upper part is bent into the engaging part 4b to form a recess into which the plate 4c loosely fits. A blocking portion 5c provided with a block 5e is formed.

Numeral 7 is a bolt inserted into the elongated hole 5d and screwed into the mounting plate 6. Numeral 8 is screwed into the blocking part 5c and the protruding end is the engaging part 4b.
This is an adjustment bolt facing the upper surface of the lower edge of.

That is, the lower part of the blocking piece 5 is fixed to the machine stand 2 fastened to the mounting plate 6 by bolts 7, and the upper part has blocking parts 5c separated by gaps on the lower edge of the engaging part 4b and on both sides of the plate 4C. placed facing each other.

As a result, when the hoisting machine 4 is vibrated due to an earthquake or the like, the blocking portion 5C collides with the lower edge of the retaining portion 4b or the plate 4c, thereby preventing excessive displacement.

This blocking piece 5 functions by being engaged with the mounting plate 6 and plate body 4C that have been processed in advance and are fixed to the stand 4a or the machine stand 2, thereby preventing a decrease in the strength of the machine stand 2 or the stand 4a and complicated machining. Can be deployed without any attachment.

Therefore, the function of preventing excessive displacement of the hoisting machine 4 can be easily obtained at a low cost.

Further, in this embodiment, the position of the blocking portion 5C relative to the plate 4C can be adjusted by the elongated hole 5d, and the permissible displacement amount of the hoist 4 in the vertical direction can be adjusted by the adjustment bolt 8.

As explained above, this invention provides an engaging part consisting of a recess and a plate fixed in the recess in the stand that constitutes the lower part of the hoisting machine, and the side surface of the machine stand that supports the above-mentioned stand in a vibration-proof manner. On the upper part of the blocking piece whose lower part is fixed to the mounting plate which is additionally fixed to the mounting plate, blocking parts are formed opposite to each other with a gap on the lower edge of the engaging part and on both sides of the plate body to prevent excessive displacement of the hoisting machine. An adjustment bolt is screwed into the blocking portion facing the upper surface of the lower edge of the engaging portion of the blocking piece and facing the upper surface of the engaging portion to adjust the permissible displacement amount of the hoist.

As a result, the blocking piece can be installed without reducing the strength of the platform or machine platform or involving complicated machining, resulting in a safe elevator hoisting machine that can easily and inexpensively prevent excessive displacement of the hoisting machine. This is to realize the following.
