Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] This invention relates to an improvement in an installation device for an elevator landing sill.

[Prior art]

First, a conventional installation device for a sill for an elevator hall system will be explained with reference to FIGS. 1 and 2.

In the figure, 1 is an elevator hoistway, 2 is a hoistway wall, and 3 is an opening for attaching an elevator landing device. 4 is a threshold for the hall device, 4a is a groove for guiding the opening and closing of the door for the hall device (not shown), and 4b is a marking line indicating the opening end of the door. The threshold 4 is an anchor bolt 5 installed on the hoistway wall 2,
It is fixed with a bracket 6 and bolts 7.

8 is a piano wire that is laid in advance at the top of the hoistway 1 and is suspended as a reference for installation centering; 9 is a piano wire;
10 is a measuring tool such as a scale.

However, in the conventional installation device for the sill 4, the sill 4 is placed on a bracket 6 which is fixed using an anchor bolt 5 driven into the hoistway wall 2, and is temporarily attached using a bolt 7.

After that, apply the scale 9 to the front surface 4c of the sill 4 and perform the work so that the score line 4b of the sill 4 matches the piano wire 8, and place the scale 10 on the front surface 4c of the sill 4.
The dimensions from the front surface 4c to the piano wire 8 were measured, and the steps were repeated until the dimensions reached the specified values to center the sill 4, and the bolts 7 were fixed and installed. .

However, with the conventional installation device described above, it is necessary to use a scorer 9 or to read the fine graduations of the scale 10. Such work is performed in the dimly lit hoistway 1, and work efficiency is extremely low. In addition, due to individual differences among workers, misunderstanding of dimensions, etc., there is a drawback that it is easy to have to return to work for rework at a later date.

[Summary of the invention]

This invention solves the above-mentioned drawbacks. By using a centering tool that can be easily attached to and removed from the sill, the installation accuracy can be made uniform regardless of the operator, and the work efficiency can be improved. The purpose is to provide installation equipment.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 3 to 6.

In the figure, the same reference numerals as in FIGS. 1 and 2 indicate the same (equivalent) parts, 11 is a centering tool, a plate 12 as a ruler that contacts the surface of the sill 4 and defines the position of the sill 4, A block 13 is inserted into the groove 4a of 4 and serves as a fixture to fix the plate 12, a bolt 14 is used to connect the plate 12 and the block 13 and is attached to the sill 4, and a bolt 14 is inserted into the groove 4a to prevent the block 13 from moving. It is composed of wing bolts 15 as screw bodies for fixing. One end of the board 12 is the threshold 4
The side surfaces 12 on both sides of the plate 12 protrude from the front surface 4c.
A notch 12b is formed at a predetermined position from the front surface 4c of the sill 4. Further, a plurality of holes 12c for inserting bolts 14 and a screw hole 12d into which wing bolts 15 are screwed are provided.

Note that the other end of the plate 12 may be made to protrude in the direction opposite to the front surface 4c of the sill 4. The block 13 has a plurality of screw holes 13a into which bolts 14 are screwed, and a large diameter 13c and a small diameter 13d into which butterfly bolts 15 are inserted.
Hole 1 in which the connection portion is tapered 13e by combining
3b, and a notch 13f is provided from one end across the hole 13b. The width of the block 13 is such that it can be fitted loosely into the groove 4a of the sill 4, and the wing bolt 15 is screwed in, and the chamfered portion 15a at the tip contacts the taper 13e of the hole 13b, and is further screwed in. Block 1 is cut by cutting depth 13f.
3 is pushed out and the side surface of the block 13 and the groove 4a
The centering tool 11 is fixed to the sill 4 by making close contact with the inner surface of the centering tool 11. That is, by tightening and loosening the butterfly bolt 15, the centering tool 11 can be freely attached and detached.

Next, the installation device of this invention will be explained. First, the groove 4 of the sill 4 temporarily attached to the bracket 6
Insert the blocks 13 of the pair of centering tools 11 into the sill 4, and align the side surface 12a of the plate 12 with the marking line 4b of the sill 4.
match, and tighten the butterfly bolt 15 to fix the centering tool 11 to the sill 4. Next, centering is performed by moving the sill 4 left and right, front and back so that the notch 12b of the plate 12 and the piano wire 8 are aligned, and the bolt 7 is aligned.
Tighten to secure the sill 4 to the bracket 6.

Therefore, when centering and installing the sill 4, there is no need to use the scorer 9 and the scale 10 as in the past, and the side surface 12a is aligned with the marking line 4b of the sill 4, and the wing bolt 15 The centering tool 11 can be attached to the sill 4 by a simple operation of tightening. Next, the notch 12b of the centering tool 11 can adjust the position of the sill 4 while observing the relative positional relationship with the piano wire 8, and perform centering installation. with uniform accuracy without occurrence of
Moreover, the threshold 4 can be installed efficiently.
Even in the elevator hoistway 1, which is dimly lit and has a poor work environment, the sill 4 can be easily and accurately installed, eliminating the need for return work for corrections and greatly improving work efficiency. Can be done.

In addition, if the other end of the plate 12 of the centering tool 11 is made to protrude in the direction opposite to the front surface of the sill 4, the centering tool 11 attached for centering the sill 4 can be used to center the sill 4.
The subsequent positioning of the three-sided frame (not shown) of the hall equipment can also be easily performed after installation.

That is, the side surface 12a of the board 12 is marked with the marking line 4b.
This marking line 4b also indicates the open end of the door. Therefore, side 12
a corresponds to the open end of the door. On the other hand, since the inner surface of the three-sided frame is installed so as to coincide with the open end of the door, the three-sided frame can also be positioned by attaching it so that the inner surface of the three-sided frame 12a is in contact with the side surface 12a.

〔Effect of the invention〕

As described above, in this invention, a mortar-shaped through hole is formed in a fixture, and the fixture, which is cut across the through hole and divided into two ends, is inserted into the threshold groove, and then the mortar-shaped through hole is inserted into the threshold groove. By inserting a screw body into the shaped through hole, the end of the fixture is widened and fixed in contact with the inner wall of the groove, and a ruler is attached to this fixed fixture, and the hanging piano wire is connected to the sill. It is designed to be installed in a predetermined position.

Therefore, the ruler can be easily fixed and integrated at any location on the threshold, and the work of centering the threshold using the piano wire can be easily performed.

Furthermore, since the ruler is attached and detached using a screw body, attachment and detachment work is also easy. It is easier to center and install the sill than when using conventional measuring tools such as scales and scales. Therefore, it is possible to reduce installation errors due to differences in worker ability and misidentification, and it has the effect of improving installation accuracy and work efficiency.
