Problems to be solved by the invention

Patent document 1 describes an insertion device (a mounting jig for a wedge-type rope end member) capable of pulling a wedge in a state in which a rope is wound into an appropriate position inside a socket when an end portion of a main rope is fastened (fixed) to a wedge-type fixing metal component (a wedge-type rope end member).

However, patent document 1 does not describe a member for guiding the grip when the pressing member is screwed and the wedge is pulled into the interior of the socket. In the case of the insertion device described in patent document 1, if there is no member for guiding the grip, the socket may be displaced in a direction orthogonal to the main rope, and the main rope may be locally damaged. In the insertion device described in patent document 1, when the pressing member is screwed in, the dimension between the receiving member and the holding member becomes large, and the pressing member and the receiving member are displaced from each other, and there is a possibility that pressing may not be performed finally.

Accordingly, the present invention provides a mounting jig and a mounting method for a wedge-type rope end member, which can ensure the quality of a rope and pull a wedge in a state in which the rope is wound into an appropriate position inside a socket while fixing an end portion of the rope used in an elevator or the like to the wedge-type rope end member.

Detailed Description

Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that substantially the same or similar structures are denoted by the same reference numerals, and when the description is repeated, the description thereof may be omitted.

Example 1

First, an elevator apparatus installed in a high-rise building will be described.

The elevator apparatus provided in the high-rise building according to the present embodiment includes a car 2, a counterweight 3, a main rope 4, a hoist 5, a compensating rope 6, and a compensating sheave 7. In the elevator apparatus, the car 2 and the counterweight 3 are connected by the main rope 4 via the hoisting machine 5, and the car 2 and the counterweight 3 are connected by the compensating rope 6 via the compensating sheave 7, and are raised and lowered in the elevator shaft 1.

When the main ropes 4 and the compensating ropes 6 are connected to the car 2 and the counterweight 3, the ends thereof are fixed by using wedge-type rope end members.

Next, a state in which a rope having a rope diameter of 12mm or less is fixed to a wedge-type rope end member will be described.

The wedge-type rope end member 8 described in the present embodiment includes a wedge 9 and a socket 10. The wedge 9 has a V-shaped inclined portion formed on an outer surface thereof. The socket 10 is provided with a housing portion for housing the wedge 9, and a wedge receiving surface 10a having a V-shaped inclination corresponding to the wedge 9 is formed at a part of an inner side surface of the housing portion.

Such wedge-type rope end members 8 are used for the main ropes 4 and the compensating ropes 6 in the case of ropes having a rope diameter of 12mm or less.

When the end portions of the main ropes 4 and the compensating ropes 6 are fixed to the wedge-type rope end member 8, the following steps are performed.

(1) First, one end of the rope (the unloaded side 4b of the main rope 4 or the unloaded side 6b of the compensating rope 6) is inserted into the housing portion of the socket 10 through the opening 10b formed in the distal end portion of the socket 10, and the one end of the rope is pulled out through the opening 10c (the opening is larger than the opening 10 b) formed on the opposite side of the opening 10 b.

(2) Next, the rope pulled out from the opening 10c is wound around the outer peripheral portion of the wedge 9 and folded back, and in this state, the wedge 9 is inserted into the housing portion of the socket 10 from the tip end portion 9a thereof.

(3) Next, the two ropes (the unloaded side 4b of the main rope 4 and the loaded side 4a of the main rope 4, or the unloaded side 6b of the compensation rope 6 and the loaded side 6a of the compensation rope 6) extending from the opening 10b to the outside of the socket 10 are pulled in the opposite direction (upward direction in fig. 2) of the socket 10, and the wedge 9 is disposed inside the housing of the socket 10.

Next, a state in which a main rope having a rope diameter of 16mm or more is fixed to a wedge-type rope end member will be described.

In particular, when the diameter of the main rope 4 is as large as 16mm or more, the work of winding the main rope 4 around the outer peripheral portion of the cleat 9 and the work of folding back can be performed by human power, but the work of pulling the cleat 9 into the main rope socket 12 cannot be performed by human power alone. Therefore, particularly when the diameter of the main rope 4 is as large as 16mm or more, a jig (device) capable of pulling the wedge 9 in a state where the main rope 4 is wound and folded back into an appropriate position in the main rope socket 12 is required.

Next, a state in which a compensating rope having a rope diameter of 16mm or more is fixed to a wedge-type rope end member will be described.

In particular, when the diameter of the compensating rope 6 is as large as 16mm or more, the work of winding the compensating rope 6 around the outer peripheral portion of the wedge 9 and the work of folding back can be performed by human power, but the work of pulling the wedge 9 into the compensating rope socket 13 cannot be performed by human power alone. Therefore, particularly when the diameter of the compensating rope 6 is as large as 16mm or more, a jig (device) capable of pulling the wedge 9 in a state where the compensating rope 6 is wound and folded back into an appropriate position in the compensating rope socket 13 is required.

Next, a main part of the mounting jig for a wedge-type rope end member described in the present embodiment will be described.

In this embodiment, a case where the main rope 4 having a rope diameter of 16mm or more is fixed to the wedge type rope end member 8 having the chock 9 and the main rope socket 12 will be described.

The mounting jig 17 for a wedge-type rope end member described in the present embodiment includes: a rope holding member 18 for holding the unloaded side 4b of the main rope 4; a pulling member 19 for pulling the rope holding member 18; a wedge positioning member 20 for determining the position of the wedge 9; a jacket positioning member 21 for determining the position of the main rope jacket 12; a jacket retaining member 22 for retaining the main rope jacket 12; a jacket installation height adjusting member 23 for adjusting the installation height of the main rope jacket 12; and a base member 24 provided with a rope holding member 18, a pulling member 19, a wedge positioning member 20, a socket positioning member 21, a socket holding member 22, and a socket installation height adjusting member 23.

The pulling member 19 is coupled to the rope holding member 18. The pulling member 19 further includes: an L-shaped fitting 19a having one end fixed to the rope holding member 18 and the other end provided to the bolt 19b of the pulling member 19; a fixed metal fitting 19c fixed to the base member 24 and having a hole through which the bolt 19b of the pulling member 19 passes; and a bolt 19b provided in the L-shaped metal fitting 19a and penetrating a hole formed in the fixed metal fitting 19 c.

The pulling member 19 has a nut 19d fitted with the bolt 19b on the L-shaped fitting 19a side of the fixed fitting 19 c. Further, the nut 19d is welded to the fixing metal fitting 19 c. Then, by rotating the bolt 19b, the bolt 19b can be moved by the action of the nut 19d (from the right side to the left side in fig. 5). Thereby, the rope holding member 18 can be pulled, and the cleat 9 in a state in which the main rope 4 is wound and folded back can be pulled into an appropriate position in the main rope socket 12.

The wedge positioning member 20 includes a contact 20b that contacts the tip 9a of the wedge 9, and a fastener 20a that fixes the contact 20b to the base member 24. That is, the contact 20b can be fixed to the base member 24 using the fastener 20 a.

By providing the wedge positioning member 20, when the wedge 9 is pulled into the main rope socket 12 using the pulling member 19, the leading end portion 9a of the wedge 9 abuts against the contact 20b, and the pull-in dimension of the wedge 9 can be made uniform.

Further, an oblong hole 20c through which the fastener 20a penetrates is formed in the contact 20 b. The contact 20b is fixed to the base member 24 by a fastener 20a via an oblong hole 20 c. Thus, the wedge positioning member 20 can be fixed at various positions according to the distance in the longitudinal direction of the oblong hole 20 c.

The pulling member 19, the wedge positioning member 20, the shoe holding member 22, and the shoe installation height adjusting member 23 are fixed to the base member 24 by bolts.

The base member 24 is formed with a notch 27. When the cleat 9 is pulled into the main rope socket 12 by the pulling member 19, the notch 27 serves as a reference for the attachment position of the cleat positioning member 20. In the present embodiment, two attachment positions serving as references can be set by the notch 27. When the mounting position to be the reference is set, the mounting position to be the reference may be marked on the base member 24 by cutting or writing, without being limited to the notch 27.

The shoe positioning member 21 is a member that determines the position of the main rope shoe 12, and is welded to the base member 24. The shoe positioning member 21 is a member that restricts the movement of the main rope shoe 12 to the rope side (left side in fig. 5) when the cleat 9 is pulled into the main rope shoe 12 by the pulling member 19.

The jacket installation height adjusting member 23 is a member for adjusting the installation height of the main rope jacket 12. This can maintain the main rope socket 12 horizontal and the main rope 4 horizontal.

Next, a description will be given of a case where the mounting jig for a wedge-type rope end member described in the present embodiment is viewed from the arrow direction a-a shown in fig. 5.

Fig. 7 is a view of the mounting jig for a wedge cable terminal member according to the present embodiment, viewed from the direction of the arrow a-a shown in fig. 5.

The rope holding member 18 is a member that holds the unloaded side 4b of the main rope 4, and includes a holding metal fitting 18a that holds the unloaded side 4b of the main rope 4 and a fastener 18b that fixes the holding metal fitting 18 a. Further, in the present embodiment, the fastener 18b has a bolt and a nut.

The rope holding member 18 is fixed to the unloaded side 4b of the main rope 4 extending from the opening 12a of the main rope socket 12 to the outside of the main rope socket 12 in the vicinity of the opening 12a (see fig. 3) of the main rope socket 12. In the present embodiment, there are two holding metal pieces 18a that hold the no-load side 4b of the main rope 4, and two fasteners 18b that fix the holding metal pieces 18a up and down. This can reliably fix the unloaded side 4b of the main rope 4.

Next, a description will be given of a case where the mounting jig for a wedge-type rope end member described in the present embodiment is viewed from the arrow direction B-B shown in fig. 5.

Fig. 8 is a B-B view of the mounting jig for a wedge-type rope end member according to the present embodiment, as viewed from the arrow direction of B-B shown in fig. 5.

When the cleat 9 is pulled into the main rope socket 12 by the pulling member 19, the socket holding member 22 can prevent the main rope socket 12 from being displaced, and can be adjusted to match the main rope sockets 12 having different sizes and shapes.

The shoe retaining member 22 includes three retainers 22a capable of retaining the main rope shoe 12 from three directions. This prevents the main rope socket 12 from being displaced, and the three movable retainers 22a can be adjusted to fit the main rope sockets 12 having different sizes and shapes.

Further, the socket retaining member 22 is fixed to the base member 24 by a fastener 22 b. Further, in the present embodiment, the fastener 22b uses a bolt.

The installation height of the main rope socket 12 is adjusted by the socket installation height adjusting member 23. This can maintain the main rope socket 12 horizontal and the main rope 4 horizontal.

Next, a method of attaching the end portions of the main ropes 4 to the wedge rope end member 8 using the attaching jig 17 for a wedge rope end member described in the present embodiment will be described.

(1) First, the main rope socket 12 is set in the socket setting height adjusting member 23 and is abutted against the socket positioning member 21, and the main rope socket 12 is fixed by the socket holding member 22 having the movable three-directional holders 22a, thereby preventing the main rope socket 12 from being positionally displaced.

(2) Next, one end of the main rope 4 (the unloaded side 4b of the main rope 4) is inserted into the housing portion of the main rope socket 12 from an opening 12a (see fig. 3) formed at the distal end portion of the main rope socket 12, and the unloaded side 4b of the main rope 4 is pulled out from an opening 12b (the opening is larger than the opening 12 a) formed on the opposite side of the opening 12a (see fig. 3).

(3) Next, the no-load side 4b of the main rope 4 pulled out from the opening 12b is wound around the outer peripheral portion of the wedge 9 and folded back, and in this state, the wedge 9 is inserted into the inside of the housing portion of the main rope socket 12 from the tip end portion 9a thereof.

(4) Next, the no-load side rope 4b of the two main ropes 4 extending from the opening 12a to the outside of the main rope socket 12 is fixed by the rope holding member 18. That is, the holding metal fitting 18a is sandwiched by two holding metal fittings 18a and fixed by two fasteners 18b fixed up and down.

(5) Next, the unloaded side 4b of the main rope 4 is pulled using the pulling member 19 connected to the rope holding member 18. That is, the bolt 19b coupled to the rope holding member 18 via the L-shaped metal fitting 19a is rotated by a wrench or the like (not shown), and the no-load side 4b of the main rope 4 is pulled in until the tip end portion 9a of the wedge 9 abuts against the wedge positioning member 20.

Thus, the wedge 9 can be appropriately provided in the housing portion of the main rope socket 12 in a stable state without locally damaging the main rope 4.

In the present embodiment, the case where the main rope 4 having a rope diameter of 16mm or more is fixed to the wedge-type rope end member having the chock 9 and the main rope socket 12 has been described in particular, but the present invention is not limited thereto. The present embodiment can be similarly applied to a case where the compensating rope 6 having a rope diameter of 16mm or more is fixed to a wedge-type rope end member having a chock 9 and a compensating rope socket 13, and a case where the main rope 4 having a rope diameter of 12mm or less and the compensating rope 6 are fixed to a wedge-type rope end member having a chock 9 and a socket 10.

As described above, according to the present embodiment, when the end portion of the main rope 4 and the end portion of the compensating rope 6 used in an elevator or the like are fixed to the wedge-type rope terminal 8, the quality of the rope can be ensured without locally damaging the rope. Further, a mounting jig 17 for a wedge-type rope end member capable of pulling the wedge 9 in a state in which the rope is wound up into an appropriate position inside the socket (10, 12, 13) can be provided.

In particular, even when the end of the thick main rope 4 having a rope diameter of 16mm or more and the end of the thick compensating rope 6 having a rope diameter of 16mm or more are fixed, the wedge 9 in a state in which the ropes are wound can be pulled into an appropriate position inside the socket (12, 13).

Next, a state in which the mounting jig for a wedge-type rope end member described in the present embodiment is combined with a table will be described.

The mounting jig 17 for the wedge-type rope end member described in the present embodiment is provided on the work table 25. This reduces the burden on the body of the operator. The base member 24 and the work table 25 are fixed to two places by bolts 28 (see fig. 5) in the present embodiment.

Example 2

Next, a main part of the jig for attaching the wedge rope end member when the wedge rope end member described in the present embodiment is disassembled will be described.

In this embodiment, a case will be described in which the main rope 4 having a rope diameter of 16mm or more is detached from the wedge-type rope end member 8 having the chock 9 and the main rope socket 12.

When the main rope 4 is detached from the wedge rope end member 8, the wedge 9 is preferably moved (from the left side to the right side in fig. 10) by restraining the main rope socket 12.

Therefore, in the present embodiment, first, the main rope socket 12 is restrained by the socket restraining member 26. Next, the pulling member 19 is fixed to the base member 24 so that the bolt 19b of the pulling member 19 contacts the contact 20b of the wedge positioning member 20.

Next, the fastener 20a of the wedge positioning member 20 is loosened. Thereby, the contact 20b of the wedge positioning member 20 can move in the longitudinal direction of the oblong hole 20c of the wedge positioning member 20.

Next, the wedge positioning member 20 is pressed in using the pulling member 19 in contact with the wedge positioning member 20. That is, the bolt 19b is rotated by a wrench or the like (not shown), and the wedge positioning member 20 is moved to press-fit the tip portion 9a of the wedge 9.

This enables the cleat 9 to be safely removed from the main rope socket 12.

In the present embodiment, the main rope 4 having a rope diameter of 16mm or more is detached from the wedge-type rope end member having the chock 9 and the main rope socket 12, but the present invention is not limited thereto. The present embodiment can be similarly used also when detaching the compensating rope 6 having a rope diameter of 16mm or more from the wedge type rope end member having the wedge 9 and the compensating rope socket 13, and when detaching the main rope 4 and the compensating rope 6 having a rope diameter of 12mm or less from the wedge type rope end member having the wedge 9 and the socket 10.

The present invention is not limited to the above-described embodiments, and includes various modifications. For example, the above-described embodiments have been specifically and specifically described for easy understanding of the present invention, and are not limited to having all the components described. Moreover, a part of the constituent elements of one embodiment may be replaced with a part of the constituent elements of another embodiment.
