Summary of the Invention

Problems to be Solved by the Invention

[0004] When an elevator is renewed, in addition to a first cable which is an existing cable, a second cable which is a newly installed cable may be newly provided. However, in the configuration described in Patent Document 1, both the first cable and the second cable cannot be sandwiched between the bracket and the pressing plate. Therefore, in this case, a new bracket and a new pressing plate capable of sandwiching both the first cable and the second cable need to be prepared, and the existing bracket and the existing pressing plate need to be replaced with the new bracket and the new pressing plate. As a result, there is a problem that the working efficiency for providing the second cable is poor.

[0005] The present disclosure has been made to solve the above-described problems, and an object thereof is to provide an elevator cable suspension device capable of improving the work efficiency for providing a second cable.

Modes for Carrying Out the Invention

[0009] Embodiment 1. FIG. 1 is a front view showing a cable suspension device of an elevator according to Embodiment 1. FIG. 2 is a plan view showing the cable suspension device of the elevator in FIG. 1. FIG. 3 is a side view showing the cable suspension device of the elevator in FIG. 1. The cable suspension device of the elevator according to Embodiment 1 includes a bracket base 1, four rail clips 2, a first bracket 3, two bolts 4 for the first bracket, a first pressing plate 5, and four bolts 6 for the first pressing plate. Further, the cable suspension device of the elevator according to Embodiment 1 includes a second bracket 7, two bolts 8 for the second bracket, a second pressing plate 9, and four bolts 10 for the second pressing plate.

[0010] The bracket base 1 is fixed to the guide rail 11 via four rail clips 2. Examples of the guide rail 11 include a guide rail for an elevator car and a guide rail for a counterweight. The bracket base 1 protrudes from the guide rail 11 in the width direction D of the guide rail 11.

[0011] The first bracket 3 is fixed to the bracket base 1 via two bolts 4 for the first bracket. The first bracket 3 protrudes from the bracket base 1 in the width direction D of the guide rail 11 and in a direction away from the guide rail 11.

[0012] The first bracket 3 and the first pressing plate 5 are arranged to face each other. The direction in which the first bracket 3 and the first pressing plate 5 face each other is a direction orthogonal to the width direction D of the guide rail 11 when viewed from above.

[0013] Two first cables 12 are sandwiched between the first bracket 3 and the first pressing plate 5. The first cable 12 is an existing cable that has been held by the cable suspension device of the elevator since before the elevator was renewed.

[0014] Two first cables 12 are sandwiched between a first bracket 3 and a first pressing plate 5 in a state where the two first cables 12 are overlapped with each other. The direction in which the two first cables 12 are overlapped with each other coincides with the direction in which the first bracket 3 and the first pressing plate 5 face each other.

[0015] With two first cables 12 sandwiched between the first bracket 3 and the first pressing plate 5, the first pressing plate 5 is attached to the first bracket 3 via four first pressing plate bolts 6. By attaching the first pressing plate 5 to the first bracket 3, the two first cables 12 are held by the elevator suspension device.

[0016] The second bracket 7 is detachably provided on the first bracket 3 via two second bracket bolts 8. The second bracket 7 protrudes from the first bracket 3 in the width direction D of the guide rail 11 and in a direction away from the guide rail 11.

[0017] The second bracket 7 and the second pressing plate 9 are arranged to face each other. The direction in which the second bracket 7 and the second pressing plate 9 face each other is a direction orthogonal to the width direction D of the guide rail 11 when viewed from above. That is, the direction in which the second bracket 7 and the second pressing plate 9 face each other coincides with the direction in which the first bracket 3 and the first pressing plate 5 face each other.

[0018] Two second cables 13 are sandwiched between the second bracket 7 and the second pressing plate 9. The second cable 13 is a newly added cable to the elevator when the elevator is renewed and is held by the elevator cable suspension device.

[0019] In a state where two second cables 13 are overlapped with each other, the two second cables 13 are sandwiched between the second bracket 7 and the second pressing plate 9. The direction in which the two second cables 13 are overlapped with each other coincides with the direction in which the second bracket 7 and the second pressing plate 9 face each other.

[0020] With two second cables 13 sandwiched between the second bracket 7 and the second pressing plate 9, the second pressing plate 9 is attached to the second bracket 7 via four bolts 10 for the second pressing plate. By attaching the second pressing plate 9 to the second bracket 7, the two second cables 13 are held by the elevator's hanging device.

[0021] Figure 4 is a front view showing the first bracket 3 of FIG. 1. Figure 5 is a side view showing the first bracket 3 of FIG. 4. The first bracket 3 is formed in a plate shape. In the first bracket 3, two first through holes 301, four second through holes 302, and two third through holes 303 are formed.

[0022] The two first through holes 301 penetrate the first bracket 3 in the plate thickness direction of the first bracket 3. One bolt 4 for the first bracket is inserted into each of the two first through holes 301.

[0023] Two through holes (not shown) are formed in the bracket base 1. The two through holes in the bracket base 1 correspond to the two first through holes 301 one by one.

[0024] With the first through holes 301 and the through holes in the bracket base 1 overlapping each other, the bolts 4 for the first bracket are inserted into the first through holes 301 and the through holes in the bracket base 1. By attaching nuts 14 to the inserted bolts 4 for the first bracket, the first bracket 3 is fixed to the bracket base 1. By fixing the first bracket 3 to the bracket base 1, the first bracket 3 is fixed to the guide rail 11.

[0025] In the plate thickness direction of the bracket base 1, the surface of the bracket base 1 facing the guide rail 11 is defined as the front surface of the bracket base 1, and the surface on the side opposite to the guide rail 11 is defined as the back surface of the bracket base 1. The first bracket 3 is in surface contact with the front surface of the bracket base 1.

[0026] In the thickness direction of the first bracket 3, the surface facing the bracket base 1 is defined as the back surface of the first bracket 3, and the surface on the side opposite to the bracket base 1 is defined as the front surface of the first bracket 3. The back surface of the first bracket 3 is in surface contact with the front surface of the bracket base 1.

[0027] The four second through holes 302 penetrate the first bracket 3 in the thickness direction of the first bracket 3. One of the four first pressing plate bolts 6 is inserted into each of the four second through holes 302.

[0028] Four through holes (not shown) are formed in the first pressing plate 5. The four through holes of the first pressing plate 5 correspond to the four second through holes 302 one by one.

[0029] With the second through holes 302 and the through holes of the first pressing plate 5 overlapping each other, the first pressing plate bolts 6 are inserted into the second through holes 302 and the through holes of the first pressing plate 5.

[0030] Four nuts 15 are fixed to the back surface of the first bracket 3. The four nuts 15 correspond to the four second through holes 302 one by one. The screw holes of the nuts 15 are arranged so as to overlap the second through holes 302. By attaching the inserted first pressing plate bolts 6 to the nuts 15, the first pressing plate 5 is attached to the first bracket 3.

[0031] The two third through holes 303 penetrate the first bracket 3 in the thickness direction of the first bracket 3. One of the two second bracket bolts 8 is inserted into each of the two third through holes 303.

[0032] FIG. 6 is a front view showing the second bracket 7 of FIG. 1. FIG. 7 is a side view showing the second bracket 7 of FIG. 6. The second bracket 7 has a first plate portion 701 and a second plate portion 702. Each of the first plate portion 701 and the second plate portion 702 is formed in a plate shape.

[0033] The first plate portion 701 and the second plate portion 702 are integrally formed with each other. The thickness direction of the first plate portion 701 and the thickness direction of the second plate portion 702 coincide with each other. The first plate portion 701 and the second plate portion 702 are arranged offset from each other in the thickness direction of the first plate portion 701.

[0034] The offset dimension between the position of the first plate portion 701 and the position of the second plate portion 702 in the thickness direction of the first plate portion 701 coincides with the thickness dimension of the first bracket 3.

[0035] The first plate portion 701 is overlapped with the back surface of the first bracket 3. In the thickness direction of the first plate portion 701, the surface facing the first bracket 3 is defined as the front surface of the first plate portion 701, and the surface on the side opposite to the first bracket 3 is defined as the back surface of the first plate portion 701. The front surface of the first plate portion 701 is in surface contact with the back surface of the first bracket 3.

[0036] In the thickness direction of the second plate portion 702, the surface facing the same direction as the front surface of the first plate portion 701 is defined as the front surface of the second plate portion 702, and the surface facing the same direction as the back surface of the first plate portion 701 is defined as the back surface of the second plate portion 702. When the front surface of the first plate portion 701 is in surface contact with the back surface of the first bracket 3, the front surface of the first bracket 3 and the front surface of the second plate portion 702 are flush with each other.

[0037] Two first through-holes 703 are formed in the first plate portion 701. The two first through-holes 703 penetrate the first plate portion 701 in the thickness direction of the first plate portion 701. The two first through-holes 703 respectively correspond to the two third through-holes 303 one by one.

[0038] With the third through-hole 303 and the first through-hole 703 overlapping each other, the second bracket bolt 8 is inserted into the third through-hole 303 and the first through-hole 703. By attaching the nut 16 to the inserted second bracket bolt 8, the second bracket 7 is detachably provided on the first bracket 3.

[0039] The second plate portion 702 is formed with four second through holes 704. The four second through holes 704 penetrate the second plate portion 702 in the plate thickness direction of the second plate portion 702. One of the four second presser plate bolts 10 is inserted into each of the four second through holes 704.

[0040] The second presser plate 9 is formed with four through holes (not shown). The four through holes of the second presser plate 9 correspond to the four second through holes 704 one by one.

[0041] With the second through holes 704 and the through holes of the second presser plate 9 overlapping each other, the second presser plate bolts 10 are inserted into the through holes of the second through holes 704 and the second presser plate 9.

[0042] Four nuts 17 are fixed to the back surface of the second plate portion 702. The four nuts 17 correspond to the four second through holes 704 one by one. The screw holes of the nuts 17 are arranged so as to overlap the second through holes 704. By attaching the inserted second presser plate bolts 10 to the nuts 17, the second presser plate 9 is attached to the second bracket 7.

[0043] Next, the procedure for holding the second cable 13 by the cable suspension device of the elevator when the elevator is renewed will be described.

[0044] With the first presser plate 5 attached to the first bracket 3, the second bracket 7 is attached to the first bracket 3 via two second bracket bolts 8.

[0045] Thereafter, with the second cable 13 sandwiched between the second bracket 7 and the second presser plate 9, the second presser plate 9 is attached to the second bracket 7 via four second presser plate bolts 10. Thereby, the second cable 13 is held by the cable suspension device of the elevator.

[0046] Thus, the procedure for holding the second cable 13 by the cable suspension device of the elevator is completed.

[0047] As described above, the cable suspension device of the elevator according to the first embodiment includes a first bracket 3, a first pressing plate 5, a second bracket 7, and a second pressing plate 9. The first bracket 3 is fixed to the guide rail 11. The first pressing plate 5 is attached to the first bracket 3 with the first cable 12 sandwiched between the first bracket 3 and the first pressing plate 5. The second bracket 7 is detachably provided on the first bracket 3. The second pressing plate 9 is attached to the second bracket 7 with the second cable 13 sandwiched between the second bracket 7 and the second pressing plate 9. According to this configuration, when the second cable 13 is newly provided, the cable suspension device of the elevator can hold the second cable 13 without removing the first bracket 3 and the first pressing plate 5 from the guide rail 11. Thereby, the working efficiency for providing the second cable 13 can be improved.

[0048] Also, in the cable suspension device of the elevator according to the first embodiment, the second bracket 7 is detachably provided on the first bracket 3 with the first pressing plate 5 attached to the first bracket 3. According to this configuration, the cable suspension device of the elevator can hold the second cable 13 while holding the first cable 12. Thereby, the working efficiency for providing the second cable 13 can be improved.

[0049] In addition, in the cable suspension device of the elevator according to the first embodiment, the configuration in which two first cables 12 are sandwiched between the first bracket 3 and the first pressing plate 5 has been described. However, a configuration in which one first cable 12 is sandwiched between the first bracket 3 and the first pressing plate 5 may be employed, or a configuration in which three or more first cables 12 are sandwiched between the first bracket 3 and the first pressing plate 5 may also be employed.

[0050] In addition, in the cable suspension device of the elevator according to the first embodiment, the configuration in which the two second cables 13 are sandwiched between the second bracket 7 and the second pressing plate 9 has been described. However, the configuration may be such that one second cable 13 is sandwiched between the second bracket 7 and the second pressing plate 9, or the configuration may be such that three or more second cables 13 are sandwiched between the second bracket 7 and the second pressing plate 9.

[0051] In addition, in the cable suspension device of the elevator according to the first embodiment, the configuration in which the first bracket 3 is fixed to the guide rail 11 by fixing the first bracket 3 to the bracket base 1 via the first bracket bolts 4 has been described. However, the first bracket 3 may be integrally formed with the bracket base 1. In this case, the first bracket 3 is fixed to the guide rail 11 by fixing the bracket base 1 to the guide rail 11.

[0052] In addition, in the cable suspension device of the elevator according to the first embodiment, the configuration in which the second bracket 7 is detachably provided on the first bracket 3 via the second bracket bolts 8 has been described. However, the configuration may be such that the second bracket 7 is detachably provided on the first bracket 3 via the first pressing plate bolts 6. That is, the configuration may be such that the first pressing plate 5 and the second bracket 7 are detachably provided on the first bracket 3 via the first pressing plate bolts 6. In this case, before the attachment of the first pressing plate 5 to the first bracket 3 by the first pressing plate bolts 6 is released, the first pressing plate 5 is pushed into the first bracket 3 via a clip (not shown). As a result, even after the attachment of the first pressing plate 5 to the first bracket 3 by the first pressing plate bolts 6 is released, the state in which the first cable 12 is sandwiched between the first bracket 3 and the first pressing plate 5 is maintained. As a result, the first pressing plate 5 and the second bracket 7 can be detachably provided on the first bracket 3 via the first pressing plate bolts 6 while maintaining the state in which the first cable 12 is held by the cable suspension device of the elevator.

[0053] The elevator cable suspension device according to the preferred Embodiment 1 has been described above. However, it is not limited to the elevator cable suspension device according to the above-described Embodiment 1. Various modifications and conversions can be made to the elevator cable suspension device according to the above-described Embodiment 1 without departing from the scope described in the claims.
