Figure 5 is a longitudinal sectional view showing a fixed state of the counterweight frame 2 of the thick plate 5 in the present embodiment.
[0018]
　In this embodiment, thick plate 5 serves as a mounting basis weight pulley, as shown in FIG. 5, the upper has a predetermined thickness dimension H1, so as to form a horizontal surface on the upper frame 2c top It is attached to the frame 2c. In this embodiment, thick plate 5 has a shape that protrudes from one of the upper frame 2c. This is the relationship between the hoist arrangement is to correspond to the specification be located off-center of the weight body balance weights pulley 4. In other words, in the present embodiment, in order to accommodate different placement specifications of the weight pulley 4, the width of the thick plate 5 is greater than the width between the pair of upper frame 2c.
[0019]
　To rigidly secure the thick plate 5 to the upper frame 2c, in the present embodiment, as shown in FIG. 5, have a shape of a cross section of substantially U (on the drawing of FIG. 5, shaped cross-section of the reverse U) disposed between the first supporting member 9 which is disposed between the upper frame 2c, (on the drawing of FIG. 5, inverted L-shaped cross section) of shaped cross-section of substantially L to the side of one of the upper frame 2c has to and using the second supporting member 10 to be. The second supporting member 10, because the thick plate 5 is in the form of protruding from the upper frame 2c, it is used to maintain the strength of the projecting portion.
[0020]
　Thick plate 5, as shown in FIG. 5, with the thick plate 5 to the upper frame 2c forming a pair is placed, a first support member 9 and the second support member 10 and a plurality of fixing bolts 11 (through It is fixed with bolts and nuts). One of the rising portion of the first support member 9 (on the drawing of FIG. 5, elongated portion below) one of the upper frame 2c and is fixed with a plurality of fixing bolts 11 (through bolts and nuts), the first support multiple other raised portion of the timber 9 (on the drawing of FIG. 5, elongated portion downward), the rising portion of the other of the upper frame 2c and the second support member 10 (the drawing, extending portions in the lower part of FIG. 5) It is fixed using a fixing bolt 11 (through bolts and nuts). In this way, the thick plate 5 is rigidly fixed to the upper frame 2c, it has sufficient strength, including the protruding portions. Incidentally, thick plate 5 of the present embodiment is different from the mounting plate described in Patent Document 1, not the mounting position is changed relative to the upper frame 2c according to the arrangement specifications of the weight pulley.
[0021]
　In this embodiment, thick plate 5 has other members, i.e., the vertical frame, a greater thickness than such upper frame. Here, the predetermined thickness of the thick plate, a thickness which is designed to have sufficient strength for fixing the weight pulley 4. In the present embodiment, as described below, it uses a threaded bolt as a mounting bolt 6 to thick plate 5 of the shaped plates 7 of U, mounting holes (female screw holes) 8 are formed in the thick plate 5. Therefore, in order to secure the fixing strength required, the thickness of the thick plate 5 is preferably assumed that the effective length of the mounting holes (female screw holes) (effective depth) can be secured. Therefore, the thickness of the thick plate 5 is to ensure the effective diameter approximately the same thickness of the attachment bolt 6 which is designed in consideration of the number of mounting bolts 6 is desirable.
[0022]
　Incidentally, a plurality of fixing bolts 11 for fixing the thick plate 5 and the first supporting member 9 to the second supporting member 10 is attached to a position that is not affected by changes in the arrangement specifications of the weight pulley 4. Specifically located a plurality of fixing bolts 11 in the vicinity of the four corners of the thick plate 5, to facilitate the change of the position in the horizontal plane of the thick plate 5 of the shaped plates 7 of U below.
[0023]
　Next, the description will be given of the mounting of the thick plate 5 of the shaped plates 7 of U which supports the bracket member 3. In this embodiment, shaped plate 7 of the U has a shape of a cross section of a substantially U, the horizontal portion (bottom portion) is mounted to the horizontal plane of the thick plate 5. Shaped plate 7 of the U supports the bracket member 3 at a rising portion (rising edge). That is, the rising portion of the shaped plates 7 of U, the vertical plate member 3a of the bracket member 3, the lower end portion of the 3b are fixed by a plurality of fixing bolts 12. Also includes a horizontal portion and the rising portion of the U of the shaped plates 7 are perpendicularly formed may be connected with R unit.
[0024]
　Shaped plate 7 of the U, for example, as shown in FIG. 4, it is mounted on the thick plate 5 at a predetermined angle with respect to the weight body balance when viewed from directly above. This causes the weight pulley 4 which is supported by the shaped plates 7 of U, the relationship between the hoist arrangement is to correspond to the specifications of placing obliquely.
[0025]
　Attachment to heavy plate 5 of the U of the shaped plate 7, as shown in FIGS. 3 and 4, is performed by a plurality of mounting bolts (threaded bolt) 6. And using the mounting bolt 6 of 8 in this embodiment.
[0026]
　The thick plate 5, in positions corresponding to the arrangement specifications of the weight pulley 4, a plurality of mounting holes (female screw holes) 8 screwing the attachment bolt 6 is tapped. Then, the horizontal portion of the shaped plates 7 of U, a position facing the mounting hole 8, an insertion hole mounting bolts 6 are inserted.
[0027]
　In a state of being inserted through the mounting bolt 6 into the insertion hole, shaped plate 7 of the U by screwing the mounting bolts (threaded bolt) 6 into the mounting hole (female screw hole) 8 of thick plate 5 is mounted on the thick plate 5, It is fixed.
[0028]
　As in the present embodiment, by attaching and fixing the shaped plates 7 of U with threaded bolts to form a female screw hole in the thick plate 5, shaped in U in a substantially arbitrary position in the horizontal plane of the thick plate 5 it can be attached to the plate 7. That is, if the mounting bolt 6 with threaded bolts as a mounting bolt 6 so screwed into the female screw hole is mounting holes 8 of the thick plate 5, when determining the position of the mounting bolt 6, the counterweight body (especially interference with counterweight frame) basically it is unnecessary to consider the position of the mounting bolt, it can be set corresponding to the arrangement specifications of the weight pulley 4. To eliminate reliably the interference between the counterweight body (especially counterweight frame) are mounting holes (female screw hole) 8 of the mounting bolt 6 formed thick plate 5, as shown in FIG. 3, thick plate 5 it is desirable that the non-through hole not penetrating the. Thus, when the mounting bolts 6 for mounting the shaped plates 7 of U a thick plate 5 becomes a leading end portion of the mounting bolt 6 does not protrude from the thick plate 5 structure, it ensures that interfering with the attachment bolt 6 is counterweight body it is possible to prevent in. Accordingly, the arrangement of the mounting bolts 6, the need to consider the positional relationship between the counterweight body is eliminated, the arrangement of the mounting bolts 6 can be freely set. Accordingly, as shown in FIG. 4, the mounting bolts 6 can be justified, the load received by each mounting bolt 6 can be equalized. This can be a mounting structure of high strength weight pulley. It is also possible to use a stud and nut in place of the mounting bolt 6.
[0029]
　In order to improve the degree of freedom of the arrangement position of the mounting bolt 6, as in the present embodiment, it is important to form the insertion hole of the bolt 6 mounted on the horizontal part with a shaped plate 7 of the U . For example, by combining two of the shaped plate L, when the side where the horizontal portion (bottom) faces you extend on the opposite side only installation range of the mounting bolt 6 becomes wider, horizontal portion of the shaped plate L interference with the head of the fixing bolt 11 is likely to occur and, because it difficult to position changes in the horizontal plane of the thick plate 5. From the viewpoint of the installation range of the mounting bolt 6 in the same manner as shaped plate 7 of the U, if the horizontal portions combined two of shaped plates L are placed so as to face can be considered (e.g., U shown in FIG. 4 If the character plate 7 and two-divided is equivalent.). However, in this case, it is necessary to keep the parallelism of the shaped plate of the two L, because handling property is lowered, shaped plate 7 of the U is more desirable.
[0030]
　In the present embodiment, according to the specifications of the installation is an elevator apparatus, in advance tapped a thick plate 5, i.e. the mounting holes (female screw hole) 8 of the mounting bolt 6 formed. Specifications of the elevator apparatus of the present embodiment, offset from the center of the weight body balance weights pulley 4, and is intended for mounting in an inclined a weight pulley 4. Thus it becomes to determine the position of the weight pulley 4 relative to the counterbalance weight body formed position of the mounting hole 8 in the thick plate 5. Thereafter, to face the horizontal section of the shaped plates 7 of U in the horizontal plane of the thick plate 5, combined with the mounting holes 8 of the insertion hole and thick plate 5 of the shaped plates 7 of U, is inserted a mounting bolt 6 into the insertion hole in state, screwed mounting bolts 6 in the mounting hole 8 of the thick plate 5, mounted and fixed shaped plate 7 of the U a thick plate 5. Then, the rising portion of the shaped plates 7 of U, the vertical plate member 3a of the bracket member 3, the lower end of 3b is fixed by fixing bolts 12. These structures, weight pulley 4 to the counterweight body is attached.
[0031]
　As described above, in the present embodiment, the weight mounting of the pulley 4 to the counterweight body, a thick plate 5 to form a horizontal surface on the upper frame 2c top fixed to the upper frame 2c, shaped cross-section of substantially U with the horizontal portion is attached by bolts 6 attached to a horizontal surface of a thick plate having a, and a shaped plate 7 of U which supports the bracket member 3 at a rising portion. By changing the mounting hole 8 position of the mounting bolt 6 formed thick plate 5 and can change the mounting position of the shaped plates 7 of U. These, it is possible to cope with various specifications regarding the mounting of the weight pulley 4 relative to the counterweight body. In other words, combining the shaped plates 7 of thick plate 5 and the U, by a fixed structure for attachment to the thick plate 5 by bolts (threaded bolt) 6 fitted with a shaped plate 7 of the U, the mounting of the shaped plates 7 of U the position change and easily, are readily adaptable to misalignment mounting and oblique attachment to hence counterweight body weight pulley 4. Thus, achieving commonality of parts between the elevator system of the plurality of specifications, the cost can be reduced.
