Abstract

<P>PROBLEM TO BE SOLVED: To provide a balance weight of an elevator capable of loading weight pieces of the number corresponding to required mass on a low suspension frame. <P>SOLUTION: Steel members are assembled to constitute the suspension frame 14, and a loading chamber 20 opened on an outer face is provided between the steel members. A plate face of the weight piece 22 formed by square platelike member is vertically arranged, and a plurality of weight pieces 22 are mutually overlapped and are loaded in the loading chamber 20. Consequently, allowance in the vertical direction becomes unnecessary in the suspension frame 14 to carry the weight piece 22 into the loading chamber 20 in order to reduce height of the suspension frame 14. Moreover, a part of the loading chamber 20 can be used to adjust elongation of a main rope and a balance rope 13. As a result, the height of the suspension frame 14 can be reduced to the height corresponding to the loading height of the required number of the weight piece 22 itself, and whole height of a hoistway is reduced to save construction costs. <P>COPYRIGHT: (C)2004,JPO

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a counterweight of an elevator having a large number of weight pieces loaded on a suspension frame suspended from a main rope.
[0002]
[Prior art]
6 and 7 are views showing a counterweight of a conventional elevator. FIG. 6 is a front view, and FIG. 7 is a vertical sectional side view of FIG. In the drawing, reference numeral 1 denotes a suspension frame formed by assembling steel materials, which is provided on an upper frame 2, a lower frame 3, a side frame 4, and an upper horizontal frame 5 and a lower side of the upper horizontal frame 5 provided in a longitudinal middle of the side frame 4. The lower horizontal frame 6 is provided. Reference numeral 7 denotes a loading chamber formed in the suspension frame 1, which is formed by a space surrounded by the upper frame 2, the side frames 4, and the upper horizontal frame 5.
[0003]
Numeral 8 denotes a weight piece, and a plurality of weight pieces are stacked one on top of the other and stacked in the loading chamber 7. Reference numeral 9 denotes a stopper for the main rope of the elevator, which is inserted and locked in the upper frame 2, 10 is a guide shoe attached to each of the four corners of the suspension frame 1 in FIG. 6, and 11 is a weight holder, provided on the side frame 4. The weight pieces 8 loaded and placed at the uppermost position are pressed down to prevent upward displacement. Reference numeral 12 denotes a notch, which is provided in the side frame 4 and opens inside the suspension frame 1 and is disposed closer to the upper frame 2. Reference numeral 13 denotes a balancing rope suspended and suspended by the lower horizontal frame 6.
[0004]
The conventional counterweight of the elevator is configured as described above, and is loaded into the loading chamber 7 in a state where one longitudinal side of the weight piece 8 is inclined through the notch 12 as shown by a chain line in FIG. It is arranged in a horizontal position. Then, the number of weight pieces 8 corresponding to the required mass are loaded in the loading chamber 7 in a flat-stacked state.
[0005]
[Problems to be solved by the invention]
In the conventional counterweight of the above-described elevator, since the weight piece 8 is carried into the loading chamber 7 in an inclined posture, between the weight piece 8 loaded on the suspension frame 1 and the lower surface of the upper frame 2, It is necessary to consider the space for carrying in. Further, since the lower end of the stopper 9 locked to the upper frame 2 is further lowered in order to adjust the elongation of the main rope, a space for elongation adjustment is required between the stopper 9 and the weight piece 8 at the uppermost position.
[0006]
In order to adjust the elongation of the balancing rope 13 as well, a space for elongation adjustment is required between the lower horizontal frame 6 and the upper horizontal frame 5. Due to these factors, the height of the suspension frame 1 increases with respect to the stacking height of the weight pieces 8 for loading the number of weight pieces 8 corresponding to the required mass. For this reason, since the upper end position of the hoistway of the elevator with respect to the normal highest position of the counterweight rises, there is a problem that the total height of the hoistway increases and the construction cost increases.
[0007]
The present invention has been made to solve such a problem, and an object of the present invention is to obtain a counterweight of an elevator capable of loading a number of weight pieces corresponding to a required mass on a short suspension frame. And
[0008]

In the counterweight of an elevator according to the present invention, a suspension frame formed by assembling steel materials and having a loading chamber formed between steel materials and having an opening on an outer surface is provided, and a plate made of a square plate-like material. A weight piece stacked in a loading chamber with a plurality of sheets superposed on each other and arranged vertically is provided.
[0009]
Further, in the counterweight of the elevator according to the present invention, a fastener for fastening the edge of the loading chamber and the weight piece loaded in the loading chamber is provided.
