  In an elevator apparatus using a flat rope as described above, for example, during installation or normal operation, dust or dirt in the hoistway may adhere to the flat rope and cause noise. In addition, with normal operation, the wax component contained in the jacket portion of the flat rope may gradually decrease with time and become depleted. In this case, noise may be generated as described above, or the jacket portion on the surface of the flat rope may be damaged due to an increased friction coefficient.

  For this reason, the flat rope can be cleaned efficiently as in the case of the round wire rope, and the wax component can be regenerated in the jacket portion of the flat rope as necessary. There is a demand for practical use of cleaning devices.

  The present invention has been made to meet such a demand, and in particular, provides an elevator flat rope cleaning apparatus capable of efficiently cleaning a flat rope.

  As described in claim 1, the present invention is a device for cleaning a flat rope by sandwiching a flat flat rope to be cleaned from both sides of the front and back and performing a relative sliding operation with the flat rope. A pair of substrates disposed opposite to each other across the flat rope, a pad disposed detachably on the flat rope side surface of each substrate, and the pair of substrates detachable from each other at a predetermined distance. And a plurality of connecting means for urging the pads against the flat rope, and each pad is soft on the surface of the highly rigid backup member. It is characterized in that the skin material is mounted so as to be removable.

  In this case, as a more specific structure of the pad, for example, as described in claim 2, a skin material is attached to the convex surface of the backup member having a substantially channel cross section so as to be removable. As the skin material, for example, a felt material or a cloth material such as cotton or knitted fabric lined with a felt material is used.

  Further, as a more specific configuration of each of the connecting means, for example, as described in claim 3, a stud bolt standing on one substrate and inserted through the other substrate, and an insertion end portion of the stud bolt It is assumed that the nut member is screwed together, and the elastic means is interposed between the other substrate and the nut member.

  Here, in the case of the cleaning specification mainly for wiping off the flat rope while applying, for example, water or a dedicated cleaner liquid as a cleaning liquid, the flat rope side of each of the substrates as described in claim 4 It is desirable that pads are arranged in a plurality of stages along the running direction of the flat rope on the surface, and the pad on one substrate side and the pad on the other substrate side are facing each other across the flat rope. .

  More specifically, as described in claim 5, the skin material of any one of the plurality of pads on each of the substrates is a wet material impregnated with a cleaning liquid, and the skin material of the remaining pads. Is preferably a dry type for wiping cleaning liquid.

  On the other hand, in the case where a finishing liquid containing wax is applied to the flat rope as a finishing process of the flat rope cleaning operation, the flat rope side surface of one of the substrates is applied as described in claim 6. A pair of pads are arranged along the flat rope traveling direction, and a single pad is placed on the flat rope side surface of the other substrate so as to be positioned within the spacing between the pads on the one substrate side. It is desirable to be arranged.

  More specifically, as described in claim 7, it is desirable that the skin material of each pad on both the substrates is a wet material impregnated with a finishing liquid containing wax.

  In this case, as described in claim 8, the pad having the wet skin material can be replenished with the cleaning liquid or the finishing liquid from the back side of the backup member while being pressed against the flat rope. Is desirable.

  More specifically, as described in claim 9, the back-up member of the pad is formed with an opening for supplying a cleaning liquid or a finishing liquid to the skin material, and the above-mentioned among the substrates. It is desirable that an opening is formed at a position corresponding to the window.

  Furthermore, as described in claim 10, when a plurality of flat ropes are arranged side by side, each pad has a length sufficient to cover the plurality of flat ropes, and the wet type More preferably, the backup member of the pad having the outer skin material has a window portion formed at a position corresponding to each flat rope.

  Therefore, in at least the first aspect of the invention, the flat rope to be cleaned is sandwiched between a plurality of pads from both the front and back sides and, for example, the car is run at a low speed so that each pad slides relative to the flat rope. By operating, the flat rope is cleaned.

  As described above, according to the flat rope cleaning device of the present invention, the cleaning device is positioned with respect to the flat rope, and the two are moved relative to each other, thereby cleaning the flat rope without depending on manual work. Since dust and the like that are likely to cause abnormal noise can be efficiently removed, the burden on the operator can be greatly reduced.

  In addition, the pad can be attached to and detached from the substrate, and the skin material can be attached to and removed from the backup member of the pad. It is possible to apply a finishing liquid such as wax to the flat rope, and it is possible to easily replace only the pad itself or the display material.

  As shown in FIGS. 1 and 2, a flat rope cleaning device (hereinafter simply referred to as a “cleaning device”) 1 faces a plurality of (three in this embodiment) flat ropes 2 arranged in parallel. It is comprised with a pair of pad units 3A and 3B to be disposed. In addition, as described in Patent Document 1, the flat rope 2 is formed by embedding a plurality of cords, which are long core materials formed of a metal material, in parallel in a jacket having a substantially flat rectangular section. is there. The jacket is formed of a flexible synthetic resin material typified by urethane resin, while each cord has flexibility obtained by twisting a plurality of strands, and is a flat rope rope. 2 as a whole is flexible in the thickness direction of the flat rope 2.

  As shown in FIG. 3, one pad unit 3 </ b> A has the same size over three steps along the traveling direction of the flat rope 2 on the surface of the substantially rectangular base plate 4 serving as the substrate facing the flat rope 2. The pad 5 is arranged. Mounting holes 6 are formed at four locations on the base plate 4 of the pad unit 3A. As shown in FIGS. 1 and 2, a stepped shaft-shaped stud is secured to the mounting hole 6 with a nut 8. Bolts 7 are erected. As shown in FIG. 6, this stud bolt 7 is inserted into the mounting hole 6 and has a male screw portion 7 a that is a fastening portion with the nut 8, and a male screw portion 7 b on the other end opposite thereto. A cylindrical guide shaft portion 7c and a large-diameter shaft portion 7d are formed, and two sets of two-surface width portions 9 are formed on the outer peripheral surface of the large-diameter shaft portion 7d. Further, a step portion 7e is formed between the guide shaft portion 7c and the external thread portion 7b.

  The other pad unit 3B has substantially the same structure as the pad unit 3A. As shown in FIG. 3, the other pad unit 3B faces the flat rope 2 out of the substantially rectangular base plate 10 as a slightly smaller substrate than the base plate 4. On the side surface, pads 5 of the same size are arranged in three stages along the traveling direction of the flat rope 2. Mounting holes 11 are formed at four positions of the base plate 10 of the other pad unit 3B, and these mounting holes 11 are formed in the guide shaft portions 7c of the stud bolts 7 as shown in FIGS. On the other hand, it is slidably inserted. Note that the common pad 5 is specified for both the one pad unit 3A and the other pad unit 3B.

  As shown in FIGS. 1 and 2, both pad units 3A and 3B are opposed to each other so that the pads 5 of both pad units 3A and 3B abut each other across a plurality of flat ropes 2, By inserting a compression coil spring 12 as an elastic body into the stud bolt 7 from the back side of the base plate 10 in the pad unit 3B, the nut 13 is tightened with respect to the male threaded portion 7b of the stud bolt 7 so that both pads The units 3A and 3B are detachably connected to each other, and the pads 5 of both pad units 3A and 3B are elastically pressed against the front and back surfaces of the plurality of flat ropes 2. As a result, the pads 5 of both the pad units 3A and 3B are sandwiched between the front and back surfaces of the plurality of flat ropes 2. As is clear from the above description, the stud bolt 7, the compression coil spring 12 as the elastic body, and the nuts 8 and 13 form a connecting means for connecting both the pad units 3A and 3B.

  When the nut 13 is tightened with respect to the male thread portion 7b of each stud bolt 7, each stud bolt is tightened until the end surface of the male thread portion 7b and the end surface of the nut 13 are flush with each other. 7 can be made uniform in the tightening amount of the nut 13.

  Here, the base plate 4 on the one pad unit 3A side shown in FIGS. 1 and 3 is formed with a long hole 14 for fixing the cleaning device 1 to a fixing member such as a beam in a hoistway through an attachment. In addition, a square hole 15 is formed which serves as a grip when the pad unit 3A is gripped. Similarly, a square hole 16 serving as a grip portion is formed in the base plate 10 on the other pad unit 3B side shown in FIGS. Further, as shown in FIGS. 1 and 3, the base plates 4 and 10 in both the pad units 3A and 3B are formed with a rectangular hole-like opening 17 that is long over the entire length of the portion where the pads 5 are mounted. Has been.

  FIG. 7A shows a front perspective view of the pad 5 alone, FIG. 7B shows a rear perspective view of the pad 5 alone, and FIG. The b direction arrow figure of is shown. Further, FIG. 8 shows an exploded perspective view of the pad 5.

  As shown in FIGS. 7A to 7C, the pad 5 is formed on the convex surface of the holder 18 having a high rigidity as a backup member, for example, a holder 18 formed by bending a metal plate into a substantially channel cross section. It is mounted so as to cover a softer skin material 19. As shown in FIG. 8 in addition to FIG. 7, the holder 18 includes a general flange portion 18 a and upper and lower side wall portions 18 b, and a lower flange portion 18 c that is further extended from the lower side wall portion 18 b. In the lower flange portion 18c, a plurality of long holes 20 having a so-called saddle hole shape are formed along the longitudinal direction.

  On the other hand, as shown in FIGS. 1, 2, and 4 and 5, the heads that are lifted from the base plates 4 and 10 by a predetermined amount are attached to both base plates 4 and 10 to which the pads 5 are to be mounted. A plurality of pins 21 are driven. Then, when mounting the pad 5 on each base plate 4, 10, the pad 5 was pressed against the base plate 4, 10 so that the large diameter portion of the long hole 20 on the holder 18 side and the head of the pin 21 matched. By sliding the pad 5 in the longitudinal direction so that the small diameter part of the long hole 20 and the shaft part of the pin 21 coincide with each other, the pad 5 can be attached to and detached from the base plates 4 and 10 on the other side. It will be firmly fixed.

  As a more detailed mounting form of the skin material 19 to the holder 18 of each pad 5, as shown in FIG. 8 in addition to FIG. In addition to projecting the portion, the collar 23 is extrapolated to the male screw portion, and then a mounting hole 24 formed in advance at the end portion of the skin material 19 is inserted into the collar 23. Further, a thin plate-like retainer 25 is overlapped on the end portion of the skin material 19, and a nut 26 is tightened on the male thread portion of the bolt 22, so that a softer skin material is applied to the convex surface of the holder 18. 19 is fixed so as to be removable.

  In this case, by using the collar 23 together, it is possible to prevent excessive tightening or insufficient tightening of the nut 26 with respect to the male thread portion of the bolt 22. As the skin material 19, as will be described later, when the skin material 19 is used as a wet material impregnated with water or a special cleaner liquid or a finishing liquid as a cleaning liquid, for example, a long wool having a thickness of about 5 mm is used. Use felt material. On the other hand, when the skin material 19 is used as a dry type mainly for wiping off the excess cleaning liquid etc. on the premise that the pad 5 having the wet skin material 19 is used together, both sides of the felt material are used. For example, a skin material 19 having a composite structure lined with two layers of cotton and knitted fabric and stitched together is used.

  As shown in FIGS. 7B and 8, the general portion 18a of the holder 18 is formed with a plurality of round hole-shaped window portions 27 along the longitudinal direction. The positions of the respective window portions 27 coincide with or correspond to the positions of the flat ropes 2 shown in FIG. 1, and at the same time, the positions of the respective window portions 27 correspond to the positions of the base plates 4 and 10 shown in FIGS. It coincides with or corresponds to the position of the opening 17.

  Next, specific functions of the cleaning device 1 configured as described above will be described.

  The cleaning device 1 according to the present embodiment is installed in a fixing member such as a beam in a hoistway where an elevator car moves up and down, a counterweight unit, a machine room, or the like.

  9 and 10 show an example of the schematic structure of the elevator as an example. In FIG. 9, the traction sheave 31 on the hoisting machine 30 side, the pulley 33 on the lower side of the car 32 and the pulley 35 on the upper side of the counterweight 334 In between, the three flat ropes 2 shown in FIG. 1 are wound. When the flat rope 2 is cleaned, the cleaning device 1 shown in FIGS. 1 and 2 is formed on the base plate 4 on the pad unit 3A side with respect to a fixing member 36 such as a beam member on which the hoisting machine 30 is installed. It is fixed through the long hole 14 and an attachment (not shown).

  Further, in FIG. 10, in addition to the traction sheave 38 on the hoisting machine 37 side, the pulley 40 on the upper side of the car 39 and the pulley 42 on the upper side of the counterweight 41, the pulley 44 on the fixing member 43 side and the uppermost part of the hoistway A plurality of pulleys 46 on the fixing member 45 side such as a beam are provided, and the three flat ropes 2 shown in FIG. 1 are wound between the traction sheave 38 and the pulleys 42, 44, 46. .

  When the flat rope 2 is cleaned, two cleaning devices 1 are used as shown in FIG. 10, and each cleaning device 1 is not fixed to a fixing member as shown in FIG. The upper part of the pulley 40 and the upper part of the pulley 42 on the counterweight 41 side are arranged with a degree of freedom of movement. The cleaning device is not always installed at a predetermined position as illustrated in FIGS. 9 and 10, but is temporarily installed when the flat rope 2 is cleaned. Will be removed.

  In both cases shown in FIGS. 9 and 10, the functions exhibited by the cleaning device 1 are the same.

  As shown in FIGS. 1 and 2, the two pad units 3 </ b> A and 3 </ b> B in which the pads 5 are arranged in the upper and lower three stages sandwich the three flat ropes 2 under the pressing force applied by the compression coil spring 13. It is out. When the flat rope 2 is cleaned, for example, if the car 32 or 39 is run at a lower speed than that during normal operation, the pads 5 of both the pad units 3A and 3B and the front and back surfaces of the flat rope 2 are accordingly sent. And relative sliding movement.

  In this case, as an actual cleaning mode, dust and the like adhering to the front and back surfaces of the flat rope 2 are wiped off while giving predetermined moisture to the front and back surfaces of the flat rope 2. Therefore, in the present embodiment, the middle pad 5 of the upper and lower three-stage pads 5 of each pad unit 3A, 3B is wet, and the remaining two upper and lower pads 5 are dry.

  For the wet pad 5, for example, a felt material is used as the skin material 19 shown in FIG. 8, and water or a dedicated cleaner liquid (liquid cleaner) is impregnated in advance as a cleaning liquid to be applied to the flat rope 2. . Further, with respect to the dry pad 5, the main point is to wipe off the excess cleaning liquid applied to the flat rope 2, and the skin material 19 shown in FIG. A composite structure in which two stacked fabrics are sewn and lined is used.

  Accordingly, based on the form shown in FIGS. 1 and 2, the pads 5 of both pad units 3A and 3B and the front and back surfaces of the flat rope 2 are relatively slid based on the low speed running of the car 32 or 39. As a result, the wet pad 5 and the dry pad 5 are used simultaneously in parallel, and the cleaning effect of the flat rope 2 is exhibited. For this reason, by wiping off the front and back surfaces of the flat rope 2 while applying the cleaning liquid, dust and the like adhering to the front and back surfaces of the flat rope 2 can be wiped and removed cleanly.

  Here, the cleaning liquid possessed by the skin material 19 of the wet pad 5 may become insufficient during the cleaning operation. In that case, as shown in FIGS. 1 and 8, the cleaning is performed through the opening 17 formed in each base plate 4 and 10 and the round hole-shaped window 27 formed in the holder 18 of the wet pad 5. The cleaning liquid can be replenished to the skin material 19 of the wet pad 5 by, for example, an injection gun without interrupting the operation.

  Further, if necessary, by adjusting the tightening of the nut 13 screwed to each stud bolt 7 connecting both the pad units 3A and 3B, the pad 5 with respect to the flat rope 2 can be adjusted. The pressing force can be adjusted.

  1 and 2, the middle pad 5 of the upper and lower three pads 5 of each pad unit 3A, 3B is wet, and the remaining two upper and lower pads 5 are dry. The position and number of wet pads 5 can be arbitrarily changed. For example, the middle pad 5 of the three upper and lower pads 5 of each pad unit 3A, 3B may be removed, and either the upper or lower pad 5 may be wet and the other pad 5 may be dry.

  Here, the cleaning of the flat rope 2 using the cleaning liquid may lead to removal of the wax component contained in the jacket portion of the flat rope 2 on the other hand. Therefore, as a finishing process of the cleaning operation of the flat rope 2, a conditioner liquid containing a wax component is applied as a finishing liquid to the flat rope 2 that has just been wiped and cleaned on both the front and back surfaces to regenerate the wax component. It is desirable. The cleaning apparatus 1 of the present embodiment can also cope with such wax application.

  11 and 12 show an example in which the arrangement of the pad 5 of the cleaning device 1 is changed for the purpose of applying wax, as is apparent from comparison with FIGS. 14 is a front view of the cleaning device 1 shown in FIG. 11, and FIG. 15 is a plan view thereof.

  In the cleaning device 1 of this wax application specification, as shown in FIGS. 11, 12, and 13, with respect to one pad unit 3A, only the middle pad 5 of the upper and lower three-stage pads 5 is left, and the other pads. 5 is removed. On the other hand, with respect to the other pad unit 3B, the middle pad 5 is removed and the upper and lower pads 5 are left.

  By doing so, the pads 5 of both pad units 3A and 3B have a so-called alternate relationship, and the pad 5 on the other pad unit 3A side is positioned between the upper and lower pads 5 on the other pad unit 3B side. It becomes a shape. Then, all the three pads 5 are wet, and the skin material 19 of each pad 5 is impregnated with a conditioner liquid containing a wax component as a finishing liquid in advance.

  In the form of the wax application specification shown in FIGS. 11 and 12, the pads 5 of both pad units 3A and 3B are in a staggered relationship with the flat rope 2 interposed therebetween, and the pads 5 are flat ropes as shown in FIG. 11 and 12, the distance between the two pad units 3A and 3B is slightly smaller than in FIGS. Therefore, when connecting both the pad units 3A and 3B with the plurality of stud bolts 7, the nut 13 screwed into the male threaded portion 7b of the stud bolt 7 shown in FIG. It shall be tightened until it abuts on the stepped portion 7e between 7b. By doing so, even if both pad units 3A and 3B come closer to each other than in FIGS. 1 and 2, they have an appropriate pressing force based on the elastic force of the compression coil spring 12 that is externally attached to each stud bolt 7. Each pad 5 can be pressed against the flat rope 2.

  In the state shown in FIGS. 1 and 2, the car 32 or 39 shown in FIGS. 9 and 10 is run at a low speed, and each flat rope 2 and each pad 5 are moved relative to each other to be included in the conditioner liquid. The wax is applied to both the front and back surfaces of each flat rope 2. Thereby, the wax component in the jacket part of each flat rope 2 is reproduced | regenerated.

  In this case, the conditioner liquid possessed by the skin material 19 of the wet pad 5 may become insufficient during the operation of the wax application specification. In this case, as shown in FIGS. 11 and 12, the wax is passed through the opening 17 formed in each base plate 4 and 10 and the round hole-shaped window 27 formed in the holder 18 of the wet pad 5. The conditioner liquid can be replenished to the skin material 19 of the wet pad 5 by, for example, an injection gun without interrupting the coating operation.

  Here, in the case where the wax coating operation under the specifications shown in FIGS. 11 and 12 is performed following the cleaning operation of the flat rope 2 under the specifications shown in FIGS. 2 may be changed from the specifications of FIGS. 1 and 2 to the specifications of FIGS. 11 and 12 by detaching the cleaning device 1 itself or the pad 5 etc., but it takes time to change the specifications. It will be. Therefore, in such a case, the cleaning device set having the specifications shown in FIGS. 1 and 2 and the cleaning device set having the specifications shown in FIGS. It is efficient to change the specification from the specification to the wax application work specification.

  Of course, even if the specifications shown in FIGS. 1 and 2 are maintained, it is possible to cope with the above-described wax application work if only the wet pads 5 are left or all the pads 5 are wet.

  Thus, according to the cleaning device 1 of the present embodiment, the positioning of the cleaning device 1 with respect to the flat rope 2 and the relative sliding operation of the two can be performed without relying on manual work. Since cleaning can be performed and dust or the like that is likely to cause abnormal noise can be efficiently removed, the burden on the operator can be greatly reduced.

  Furthermore, since each pad 5 can be attached to and detached from the base plates 4 and 10 of each pad unit 3A and 3B, and the skin material 19 can be attached to and detached from the holder 18 of each pad 5, By changing the arrangement of the pad 5 as necessary, for example, it becomes possible to apply wax to the flat rope after the completion of the cleaning operation, which is advantageous in terms of versatility, and the skin material 19 is stained. When it becomes severe, the pad 5 itself or the skin material 19 alone can be easily replaced.
