BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1 FIG. Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. 1 and 2 are side views showing Embodiment 1 of the present invention. FIG. 1 shows a normal state, and FIG. 2 shows a state during adjustment.

In each figure, 6, 7, 7a to 7c, 8,
8a, 8b, 14 and 15 are the same as those described above (see FIG. 9). The configuration of the entire elevator apparatus (not shown) is as shown in FIG. In this case, it is assumed that the shackle lot 8b of the rope shackle 8 is configured to be longer than the conventional one (see FIG. 9).

Reference numeral 7d denotes a cutout formed in the inner wall of the vertical frame 7b, which is used when an adjusting weight piece (described later) is attached to and detached from the lower inner wall of the upper frame 7a. Reference numeral 17 denotes a patch plate provided on the inner wall of the upper frame 7a, and a shackle lot 8b.
Is penetrated and is fixed by the lock nut 14,
It has a function similar to that of the above-described rope stopper plate 13 (see FIG. 9).

Numeral 18 denotes an adjusting weight piece having a thin plate structure for adjusting the length of the main rope 6, which is mounted on and stored on the balancing weight piece 15, and which is connected to the lower inner wall of the upper frame 7a and the abutment plate 17.
And the required number are stacked. Adjusting weight piece 1
8 is interposed by the required number for adjusting the length of the main rope 6 on the lower surface side of the upper frame 7a, and the shackle lot 8b is penetrated similarly to the backing plate 17.

Numeral 19 denotes a jack bolt provided so as to penetrate the upper frame 7a from the upper surface of the upper frame 7a, and raises the counterweight 7 as necessary when adjusting the run-by D (see FIG. 11). A gap G (see FIG. 2) is formed between the lower surface of the upper frame 7a and the backing plate 17. In this case, a screw hole corresponding to the jack bolt 19 is formed in the upper frame 7a. 19a is a jack bolt 19

On the other hand, when adjusting the length of the main rope 6, first, the lock nut 19a is loosened, and then the jack bolt 19 is rotated in the tightening direction so that the jack bolt 19 is moved toward the lower surface of the upper frame 7a. Screw it in.

As a result, the jack bolt 19 moves while passing through the cutout portion 18b of each adjustment weight piece 18, and when its lower end abuts against the backing plate 17, the counterweight 7 moves upward. Therefore, as shown in FIG. 2, a gap G corresponding to the rising distance of the counterweight 7 is formed in the lower portion of the upper frame 7a.

When the gap G is formed as shown in FIG. 2, the adjusting weight piece 18 is released from the shackle lot 8b and the jack bolt 19, so that the adjusting weight piece 18 is cut through the notches 18b and 18c. The shackle lot 8b and the jack bolt 19 can be freely removed and attached from the side surfaces. Therefore, when the main rope 6 is stretched due to aging, the adjustment weight piece 18 is placed on the backing plate 17 in order to fix the counterweight 7 at the raised position.
May be inserted and placed.

That is, the adjustment weight piece 18 placed on the balancing weight piece 15 is taken out of the vertical frame 7b through the notch 7c (see FIG. 2), and subsequently, the vertical weight is inserted through the notch 7d. 7
Insert again into b. Then, the notch 1 of the adjustment weight piece 18
The shackle lot 8b and the jack bolt 19 are inserted into the 8b and 18c, and the adjustment weight piece 18 is
It is placed on the stack.

When the adjustment weight pieces 18 are placed on the backing plate 17 by the number necessary to sufficiently secure the run-by D, the jack bolt 19 is rotated in the reverse direction to rotate the upper frame 7.
is moved in a direction protruding from the upper surface of a. This allows
The counterweight 7 is lowered by a distance corresponding to the gap G, and is positioned with the required number of adjusting weight pieces 18 interposed between the upper frame 7a and the backing plate 17 (return to the state of FIG. 1). .

As described above, the jack bolt 19 is lowered to form a gap G in the lower portion of the upper frame 7a, and an arbitrary number of adjustment weight pieces 18 are stacked and mounted on the backing plate 17, and then the jack bolt 19 is again removed. By ascending, even when the main rope 6 is elongated due to aging, the run-by D can be easily secured to a predetermined size using only the spanner.

Therefore, various tools (square members 10 and chain blocks 11) as in the related art (see FIG. 11) are not required, and terminal treatment (babbit treatment) of the main rope 6 is not required. Lambai D in a short time
Adjustment work can be completed. Further, since the necessary number of the adjusting weight pieces 18 before use are previously deposited on the counterweight pieces 15 in the counterweight 7 in advance, it is possible to save the trouble of bringing the adjusting weight pieces 18 to the site. it can.

Embodiment 2 In the first embodiment, the required number of adjusting weight pieces 18 are stacked and mounted on the caul plate 17 as the caul plate position adjusting means to secure the run-by D, but the caul plate 17 is locked. The pin to be inserted into the vertical frame 7b

Is similar to The configuration of the entire elevator apparatus (not shown) is as shown in FIG.

In FIG. 6, reference numeral 22 denotes an adjustment weight piece divided into two parts, and reference numeral 23 denotes a rod for integrally joining the adjustment weight pieces 22 together. Before use, the adjustment weight piece 22 integrated via the rod 23 is placed on the counterweight piece 15 in the same manner as described above.

FIG. 7 is an enlarged perspective view of the adjustment weight piece 22 in FIG. 6. In FIG. 7, reference numeral 22a denotes a protrusion provided at both ends of each adjustment weight piece 22, and 22b denotes each adjustment weight. Each pair of holes is formed in the opposing surface of the piece 22. A pair of rods 23 that join the respective adjustment weight pieces 22 are detachably inserted at both ends into the holes 22b, and are disposed so as to bypass the positions of the rope shackle 8 and the jack bolt 19.

In FIG. 6, the adjustment weight piece 2 extends from the vertical frame 7b.
When taking out 2, the adjusting weight piece 22 in the balancing weight 7 is used.
, The rod 23 is pulled out from the hole 22b.
As a result, the adjustment weight piece 22 is disassembled into a total of four parts each including the two adjustment weight pieces 22 and the rod 23, so that the vertical frame 7b can be formed without the notch 7c (see FIG. 1). It can be easily taken out.

When the adjustment weight piece 22 is stored in the vertical frame 7b, the adjustment weight piece 22 and the rod 23 are stored in the vertical frame 7b in a disassembled state, and are tilted in the vertical frame 7b. After the rod 23 is inserted into the hole 22b to form an integral structure, the adjustment weight piece 22 may be brought into a horizontal state.

As described above, by using the adjusting weight piece 22 having the divided structure, the adjusting weight piece 22 can be easily taken in and out without the notches 7c and 7d. Further, since the pair of rods 23 are arranged so as to bypass the rope shackle 8 and the jack bolt 19, the notches 18b and 18c (see FIG. 3) are not required.
