Description

  The present invention relates to an elevator renewal construction method and a wiring path that connects an elevator control panel and a hoistway, and in particular, as the elevator is renewed, the control panel of a machine room is updated and the hoistway is updated from the updated control panel. The present invention relates to an elevator renewal construction method when newly laying various wirings and a wiring path for connecting an elevator control panel and a hoistway.

  When renewing, that is, renewing, for example, an elevator model installed in a building such as a building, a hoistway in which the elevator car moves up and down is used as it is, and the lifting equipment including the car is updated. Along with this, the control panel is also updated, and various wirings connecting the control panel, the car, and the operation unit of each floor are also updated. For example, when an elevator installation is renewed after 10 or 20 years, the wiring material itself of the various wirings is significantly different with the progress of technology, and various wirings used in the control panel with new performance may be completely replaced. Many. For example, it is necessary to replace various wirings, which used to be a set of disjoint single wires, with a single cable that is composed of several tens of cores.

  Usually, the control panel of an elevator is installed in the machine room provided in the uppermost part or the lowest part of a hoistway. And in order to connect the various wirings from the control panel to the car and the operation section of each floor landing, a hoistway that is a space penetrating the building up and down is used. And in order to let various wiring from a control panel pass in a hoistway, a through-hole is provided in the floor of a machine room, a ceiling, or a wall. Therefore, various wirings from the control panel are laid from the control panel to the floor of the machine room toward the opening and enter the hoistway from the opening. Various wirings laid on the floor or the like of the machine room are embedded so as to be integrated with the floor using an appropriate burying material for protection. Various wirings in the hoistway are housed in an appropriate duct or the like, and branched and wired to a car, each floor operation unit, or the like.

  Here, when the elevator facility is renewed, the control panel and various wirings are updated as described above, and therefore, it is necessary to pass these various new wirings through the new control panel to the hoistway. Various wirings up to now are buried in the floor of the machine room as described above, and pass through ducts or the like that match the various wirings so far in the hoistway, so that they cannot be diverted as they are. Therefore, construction for newly providing a through hole on the floor of the machine room or the like is newly performed for various types of wiring with new specifications.

  As described above, in the conventional elevator renewal work, in order to lay various new wirings, a new through hole leading to the hoistway is provided in the floor of the machine room or the like. In this case, since a device such as a chipping work for a floor or a vibration drill for drilling is used, vibration or noise is given to an already used building. In addition, other electrical wiring not related to the renewal work, as well as pipes such as water and gas, may be embedded in the floor of the machine room, etc. Care must be taken not to damage them.

  Therefore, the elevator renewal work according to the prior art requires considerable work such as opening a through hole leading to the hoistway for laying various wirings.

  An object of the present invention is to provide an elevator renewal construction method that eliminates the need for special drilling work and a wiring path that connects an elevator control panel and a hoistway.

The elevator renewal construction method according to the present invention is a construction method in which the control panel of the machine room is updated in accordance with the renewal of the elevator, and various wirings are newly laid from the updated control panel to the hoistway. A guide sleeve provided in the machine room for passing various existing wires from the control panel to the inside of the hoistway, and extending from the through hole to the hoistway for passing various wires ; Of the hoistway signal line duct having an opening larger than the outer shape of the pipe portion of the guide sleeve and provided along the hoistway, and passing through the lower portion of the pipe portion of the guide sleeve, the guide sleeve is disposed on the hoistway side. a cutting step of cutting in the introduction, the removal step of removing a portion of the guide sleeve remaining in through opening, a protective sleeve when passing the new various wirings, and the hoistway signal line duct An installation step of installing a port through a protective sleeve having a length that does not negotiations, a new variety of wiring through the protection sleeve opening through the updated control panel that turning hoistway signal line duct, and that And a laying step of laying in the hoistway so as to hang outward .

  In the laying step, it is preferable that a protective duct is provided from the updated control panel to the protective sleeve of the through hole, and various wirings are laid therein.

In addition, the wiring path that connects the elevator control panel and the hoistway according to the present invention is updated from the updated control panel toward the hoistway with the renewal of the elevator. This is a new wiring route for various wirings, and uses the through holes provided in the machine room to pass the various existing wirings from the already installed control panel through the hoistway and to pass various wirings. A guide sleeve that extends from the through hole into the hoistway, and an opening that is larger than the outer shape of the tube portion of the guide sleeve and that is provided along the hoistway. of the hoistway signal line duct is passed, the guide sleeve is cut in the introduction of the hoistway, by removing the portion of the guide sleeve remaining in through opening, encounters protective sleeve when passing the new various wires Hoistway signal Has a length that does not interfere with the duct, the new various wiring that turning hoistway signal line duct, and through opening the protective sleeve for installation in so hanging on the outside in the hoistway is installed And a protective duct provided on the floor of the machine room through which various wires pass from the updated control panel to the protective sleeve of the through hole.

  With the above configuration, the guide sleeve provided to extend into the hoistway from the conventional through hole is cut at the introduction part on the hoistway side, and the portion of the guide sleeve remaining in the through hole is removed there. A protective sleeve is installed in the through-hole, and various new wirings are laid in the hoistway through this. Thus, since a conventional through hole is used, no special drilling work is required to pass various wires from the control panel to the hoistway.

  In addition, since a protective duct is provided from the new control panel to the protective sleeve of the through-hole, and various wirings are laid therein, it is possible to easily lay various new wirings without digging up the conventional various wirings. it can.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the following description, the machine room in which the control panel of the elevator equipment is arranged is described as being on the hoistway, that is, on the ceiling of the uppermost floor where the elevator moves up and down. A chamber may be provided. For example, it may be below the hoistway and below the floor of the lowest floor where the elevator goes up or down, or may be a place that is not above or below the hoistway. In these cases, the through holes through which various wires from the control panel pass through the hoistway can be provided not on the floor of the machine room but on the ceiling or wall.

  FIG. 1 is a diagram illustrating the state of various wiring paths before and after the elevator renewal work. Here, in FIG. 1, (a) and (b) show the wiring path 30 before the elevator renewal work, and (c) and (d) show the wiring path 60 after the elevator renewal work, respectively. Of these drawings, (a) and (c) are longitudinal sectional views of the building along the hoistway 10, and (b) and (d) are plan views of the respective machine rooms 12. It is. 1A shows a cross-sectional view taken along line AA shown in FIG. 1B with respect to the wiring path 30, and FIG. 1C shows the wiring path 60 shown in FIG. A sectional view taken along line CC is shown.

  First, the wiring path 30 before the elevator renewal work will be described, and then the wiring path 60 after the elevator renewal work will be described while comparing with this, and then the detailed procedure and contents of the elevator renewal work method will be described.

  FIGS. 1A and 1B are diagrams showing a state of the wiring path 30 before the elevator renewal work, that is, the wiring path 30 laid so far. A machine room 12 in which equipment for operating the elevator is arranged is provided at the upper part of the elevator hoistway 10 provided vertically through the building. Accordingly, the floor 14 of the machine room 12 is also the ceiling of the hoistway 10. A car 16 supported by a main rope is installed in the hoistway 10, and the car 16 ascends and descends while stopping at each floor landing 18 as the main rope is driven. Each floor hall 18 is provided with an operation panel 20 that requests the car 16 to stop. On the other hand, a drive motor (not shown) for driving the main rope is installed in the machine room 12, and a control panel 32 and the like for controlling the operation of the entire elevator facility are arranged.

  In general, the wiring path is constructed by laying various wirings for transmitting an electrical signal or the like from the control panel 32 to each element of the elevator equipment including the drive motor. In FIG. 1, only the wiring path 30 related to the various wirings 34 passing through the hoistway 10 among the various wirings connected to the control panel 32 is illustrated. The various wirings 34 include a connection between the control panel 32 and the car 16 and a connection between the control panel 32 and the operation panel 20 of each floor hall 18. The various wirings 34 depend on the installation time of the elevator so far, but in the case of installation before the 1980s, for example, there are cases where the number of core wires is 100 or more in a set of single-core coated conductors.

  The wiring path 30 is connected to the control panel 32 of the machine room 12 from the control panel 32 of the machine room 12 to the car 16 of the hoistway 10 and the operation panel 20 of each floor landing 18 (control panel 32) -buried pipe 48-through port 40. Each element is provided in the order of the guide sleeve 44, the hoistway signal line duct 46 (the car 16, the operation panel 20).

  The buried pipe 48 is a protective pipe that accommodates various wirings 34 therein. As the buried pipe 48, for example, a metal pipe having an inner diameter of 60 mm and an outer diameter of about 100 mm or a rigid plastic pipe can be used. Specifically, the buried pipe 48 is laid out as follows. That is, various wirings 34 from the control panel 32 are placed on the floor 14 of the machine room 12 through the inner diameter of the buried pipe 48, covered with an appropriate buried material such as mortar from above, and the floor of the machine room 12 is flattened. To do. The thickness of the buried material covering the buried pipe 48 may be, for example, about 3 mm at the thinnest place.

  The through hole 40 is an opening that is opened in the floor 14 of the machine room 12 toward the hoistway 10. The through hole 40 is a wiring passage having a function of passing various wirings 34 that have passed through the buried pipe 48 in the machine room 12 toward the hoistway 10. The through hole 40 is opened when an elevator facility is installed in a building. That is, normally, when a building is built, it is designed and provided with an opening. For example, the size of the through hole 40 is about 100 mm square.

  The through hole 40 is provided with a case 42 and a lid 50. The case 42 is a member that has an upper opening that is covered with the lid 50, has an opening that is smaller than the upper opening at the center of the bottom, and is a through member that fits into the through hole 40. On the side surface of the case 42, a wiring port for introducing various wirings 34 passing through the buried pipe 48 is provided. The lid 50 is a member that covers the upper opening of the case 42. By opening the lid 50, the state of various wirings 34 in the through hole 40 can be examined. By closing this, the through hole 40 is blocked, which is unnecessary. It has a function to prevent things from being mixed into the through hole 40. The case 42 and the lid 50 can be obtained by processing an appropriate metal plate material, or can be obtained by molding an appropriate plastic material.

  The guide sleeve 44 is a flanged pipe member that is fitted into the bottom of the case 42 and has a function of guiding various wires 34 to the hoistway 10 side. The outer shape of the tube portion of the guide sleeve 44 is smaller than the size of the opening at the bottom of the case 42, and the outer shape of the flange portion of the guide sleeve 44 is larger. Therefore, the guide sleeve 44 is disposed so that the flange portion is supported on the bottom of the case 42 and the tube portion extends toward the hoistway 10. Various wires 34 introduced from the side surface of the case 42 pass through the inner diameter of the guide sleeve 44 and are guided by the guide sleeve 44 to guide the through hole 40 toward the hoistway 10. The guide sleeve 44 can be obtained by processing an appropriate metal plate, or can be formed by molding an appropriate plastic material.

  The hoistway signal line duct 46 is a cylindrical member that is provided along the hoistway 10, passes various wirings 34 in the hoistway 10, and branches out toward the outside, that is, the hoistway 10 at a necessary position. . The size of the upper opening of the hoistway signal line duct 46 is set larger than the outer shape of the pipe portion of the guide sleeve 44, and the lower portion of the pipe portion of the guide sleeve 44 is passed through the hoistway signal line duct 46. As a result, the various wires 34 guided through the inner diameter of the guide sleeve 44 are guided into the hoistway signal line duct 46 and branched at an appropriate position, and the car 16 and the operation panel 20 of each floor landing 18. Connected to each. The hoistway signal line duct 46 can be obtained by sheet metal processing of an appropriate metal plate material, or can be obtained by molding an appropriate plastic material.

  In this way, the wiring path 30 before the elevator renewal work passes from the control panel 32 through the buried pipe 48 that is covered with the buried material on the floor 14 of the machine room 12 and passes through the case 42 of the through hole 40. Enters the space defined by the case 42 and the lid 50 from the side inlet, and is guided through the inner diameter of the guide sleeve 44 into the hoistway signal line duct 46 disposed in the hoistway 10. That is, the various wirings 34 are laid from the control panel 32 toward the hoistway 10 while being protected by these wiring protection members.

  Next, the wiring path 60 after the elevator renewal work will be described. Here, the same elements as those of the wiring path 30 before the elevator renewal work are denoted by the same reference numerals, and detailed description thereof is omitted. In the elevator renewal, the control panel 62 is newly updated here. Accordingly, various wirings 64 are also updated with a new configuration. For example, the new various wirings 64 are a 36-core cable that combines 36-core signal lines into one, a 44-core cable that combines 44-core signal lines into one, and a 60-core signal line that is combined into one 60 Consists of a core cable or the like. An optical fiber cable may be included. Therefore, the new wiring path 60 is basically a cable laid, and is easier to handle than the conventional wiring path 30 which is a set of more than 100 single core wires.

  The wiring path 60 is connected to the control panel 62 of the machine room 12 from the control panel 62 of the machine room 12 to the car 16 of the hoistway 10 and the operation panel 20 of each floor landing 18 (control panel 62) -machine room duct 68-through port. Each element is provided in the order of 40-protection sleeve 66- (car 16, operation panel 20). Here, the case 42 and the lid 50 remain unchanged, but the protective sleeve 66 is used instead of the guide sleeve 44.

  The machine room duct 68 is a protective duct that houses various wirings 64 therein. The machine room duct 68 is disposed on the floor 14 of the machine room 12 separately from the conventional buried pipe 48. Specifically, the machine room duct 68 is laid out as follows. That is, various wirings 64 from the control panel 62 are arranged on the floor 14 of the machine room 12 and covered with the machine room duct 68 so as to cover it. As a result, the various wirings 64 from the control panel 62 are protected by the machine room duct 68, passed through the duct 64, and led from the introduction port on the side surface of the case 42 to the space defined by the case 42 and the lid 50. The machine room duct 68 can be obtained by sheet metal processing of an appropriate metal plate material, or can be obtained by molding an appropriate plastic material.

  The protective sleeve 66 is a flanged tube member fitted to the bottom of the case 42 and having a function of protecting the various wires 34 and passing them through the hoistway 10 side. That is, one side of the tube portion is a flange portion having an outer shape larger than the bottom opening of the case 42, and the other side has an outer shape that spreads out. The protective sleeve 66 has a length that does not interfere with the conventional hoistway signal line duct 46. Therefore, the protective sleeve 66 is arranged so as not to enter the hoistway signal line duct 46. The protective sleeve 66 can be obtained by molding a suitable plastic material, or a molded metal material may be used.

  Thus, the wiring path 60 after the elevator renewal work passes from the control panel 62 through the machine room duct 68 provided on the floor 14 of the machine room 12, and from the side inlet of the case 42 of the through hole 40 to the case. 42 enters the space defined by 42 and the lid 50, and is led to the hoistway 10 from there through the inner diameter of the protective sleeve 66. Since the various wires 64 coming out from the flared portion of the protective sleeve 66 are actually several cables, they do not particularly require protection of ducts and the like, branch off at an appropriate position, and the car 16 and each floor landing 18. Are connected to the operation panel 20, respectively.

  In the elevator facility having the above-described structure, the procedure of the elevator renewal work for newly laying the wiring path 60 for the elevator renewal will be described in detail below. FIG. 2 is a flowchart showing the procedure of the elevator renewal work, and FIGS. 3 to 7 are views showing the structure in the vicinity of the through hole 40 in each procedure. Elevator renewal work includes upgrade of elevator equipment including a car, update of control panel, and update of various wiring associated therewith. Here, update wiring construction of various wiring will be mainly described. The update installation of the control panel may be performed before or after the laying of various wirings, or the lifting equipment including the car may be updated first or last. The order of these renewal works may be changed as appropriate according to the building situation and the content to be updated.

  The renewal laying of various wirings associated with the renewal of the elevator is performed by stopping the operation of the conventional elevator equipment and disconnecting all the supplies of power and the like. First, the guide sleeve 44 is cut (S10). Specifically, the guide sleeve 44 is cut at a ceiling portion of the hoistway 10, that is, at the hoistway 10 side that is the back side of the floor 14 of the machine room 12. It is desirable that the cut portion be as close to the ceiling portion of the hoistway 10 as possible before the guide sleeve 44 is inserted into the hoistway signal line duct 46.

  This is shown in FIG. Here, a state in which the guide sleeve 44 is cut from the side surface by the rotary circular saw device 70 is shown. As the rotary circular saw device 70, a device that rotates a cutter provided with a diamond blade on the outer periphery of a disk at high speed can be used. In the case of the above dimension example, the rotating circular saw device 70 having a cutter with a diameter of, for example, about 180 mm can be used. Those having a dust absorbing function are preferable. In the case of the guide sleeve 44 having the above dimensions and materials, the cutting operation can be completed in several tens of seconds.

  In FIG. 3, the cutting is performed while the conventional various wirings 34 are laid. When various wirings 34 left in the hoistway signal line duct 46 and the buried pipe 48 can be left as they are after cutting, the work efficiency is improved by doing so. On the other hand, when it is necessary to cleanly remove the various wirings 34 in the hoistway signal line duct 46 and the buried pipe 48, the conventional various wirings 34 are separately provided before the step S10 in consideration of the removal procedure. It may be removed by cutting or the like.

  Next, the guide sleeve 44 is removed (S12). In the previous step, the guide sleeve 44 is separated into two bodies, and the cut lower portion is free-falling unless it is previously fixed to the hoistway signal line duct 46. Therefore, the guide sleeve remaining in the case 42 is removed.

  FIG. 4 shows the state of the guide sleeve 45 left in the case 42 by cutting. The guide sleeve 45 is removed from the machine room 12 side with the lid 50 opened. Prior to this, at least the various wires 34 remaining in the case 42 and the guide sleeve 45 are also removed. The various wirings 34 may be removed by removing the various wirings 34 from the original control panel 32 so as to be free ends and pulling them out from the case 42 side. When this is troublesome, various wirings may be cut with an appropriate cutting tool at the side surface inlet of the case 42. After the various wires 34 are removed, the flange portion of the guide sleeve 45 is pulled upward, and the guide sleeve 45 is pulled out from the bottom opening of the case 42 and removed. FIG. 5 is a diagram illustrating a state where the remaining guide sleeve 45 and various wirings 34 are removed.

  Next, the protective sleeve 66 is installed (S14). The protective sleeve 66 has a divergent shape, and its curvature is smooth so as to guide the cables constituting the newly laid various wires 64 without damaging them, and at the bottom opening of the case 42. Shaped into a shape that can be inserted. For the insertion, the protective sleeve 66 may be slightly inclined from the upper side of the case 42, that is, from the machine chamber 12 side, and may be inserted into the bottom opening of the case 42 from a part of the divergent shape. FIG. 6 is a view showing a state where the protective sleeve 66 is inserted and installed in the bottom opening of the case 42.

  Then, various new wirings 64 are laid (S16). Specifically, one end side of each wiring 64 is placed on the connection part side of the new control panel 62 and arranged on the floor 14 of the machine room 12. And the other end side of various wiring 64 is inserted in the internal diameter of the protection sleeve 66, and hangs down to the hoistway 10 side. Here, the various wirings 64 that are hung are hung outside the original hoistway signal line duct 46 so as not to enter the hoistway signal line duct 46. Thereafter, the machine room duct 68 covers the various wires 64 arranged on the floor 14 of the machine room 12 (S18). Before and after that, one end of each wiring 64 is connected to a new control panel 62, and the other end is connected to the car 16 and the operation panel 20 of each floor hall 18.

  In this way, the wiring paths 60 of various new wirings 64 are laid in the elevator renewal, and the elevator renewal work is performed along with the update of the control panel 62 and the lifting equipment. As described above, in this elevator renewal work, the on-site working work can be completed in several tens of seconds just by cutting the guide sleeve 44 using a simple cutting device. This eliminates the need for special drilling work to open the opening to the machine room, and does not require large-scale construction facilities. In addition, the construction period can be shortened and the influence on the use of the building can be reduced. Further, unnecessary buried pipe 48, hoistway signal line duct 46, or remaining conventional wiring 34 can be left as they are, so that no extra removal work is required and the appearance is impaired. There are few things.
