Description

  The present invention relates to an elevator cable erection device and an elevator cable erection method, and more particularly to an elevator cable erection device and an elevator cable erection method for erection of an elevator cable.

  The service life of elevators such as elevators is generally about 20 to 25 years. When used for many years, each device and equipment such as elevator control panels, hoisting machines, and brake mechanisms deteriorate due to aging. Renovation work (so-called modernization work) and repair work are being carried out in order to improve the functions and safety of aging elevators.

  In renovation work and repair work, all or part of the elevator is remodeled or replaced. Therefore, it is necessary to stop the elevator during the construction period. In particular, the renovation work takes a long time from the removal of the existing part of the elevator to the installation of new equipment, and the period of stopping the elevator also takes a long time.

  As a result, the user cannot use the elevator for a long time. For this reason, shortening the stop period of the elevator during the construction period is desired. In particular, when only one elevator is installed, such as a house or office, it is strongly desired to shorten the stop period of the elevator.

  For example, Japanese Laid-Open Patent Publication No. 2000-44142 (Patent Document 1) proposes an elevator control cable replacement method in which only an existing control cable of a movable portion that has deteriorated over time is replaced with a new cable. In this elevator control cable replacement method, the existing control cable is replaced between the cable connection box provided on the hoistway side and under the car. The movable part that bends and moves as the car moves up and down in the hoistway is replaced, so it is necessary to remove the existing control cable that does not deteriorate other fixed stationary parts. There is no. Therefore, the replacement work time can be shortened, and the user's non-movable time can be reduced.

JP 2000-44142 A

  However, the elevator control cable replacement method disclosed in this publication has two extra connection boxes, and the existing control cable and the new control cable are connected to the connection box. Since work occurs, the work time cannot be shortened.

  Also, in renovation work where the control system is changed, the cable standards (signals) are almost the same between the new control cable and the existing control cable installed more than 20 years ago, so it is not possible to divert the existing control cable. Yes, this replacement method cannot be implemented. Therefore, all the wires are inevitably replaced, and the work time is increased. As described above, this replacement method is inconvenient for the user due to the long stop time of the elevator.

  Also, in the construction method generally used when exchanging all wires, a control cable (cable) is set on a car or a jig (turntable) placed on the landing, and the cable is rotated while turning the jig. Is being sent out. In this jig / tool, an operator for sending out the cable is required in addition to the operator for constructing the cable, and the construction of the cable is a labor-intensive operation. Therefore, workability of cable laying is poor.

  SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide an elevator cable erection device and an elevator that allow a cable erection operator to replace the cable in a short time by improving the cable erection workability. It is to provide a cable erection method.

  In the above description, the case where the claw 10a is disposed outside the gear 10b has been described. However, a configuration in which the claw 10a is disposed inside the gear 10b may be employed.

  Next, an elevator cable erection method using the elevator cable erection device will be described. Hereinafter, the elevator cable erection method in the case where all the cables 20 are erected will be described.

  First, with reference to FIG. 2, the method to install the cable 20 in the elevator cable construction apparatus 1 is demonstrated. The cable 20 is generally packaged in a spiral shape. After the cable 20 is unpacked, the cable 20 is placed on the base 2 in a spiral shape, and one end of the cable 20 is fixed to the fixing band 7. Thereby, the time which sets the cable 20 to the elevator cable construction apparatus 1 can be shortened.

  Although the setting time becomes long, after the cable 20 is unpacked, the cable 20 may be wound around the rotating drum 5 little by little from the state in which the cable 20 is fully extended, and the cable 20 may be set in the elevator cable laying device 1. .

  After the cable 20 is set in the elevator cable laying apparatus 1, the enclosure part 3 prevents the cable 20 that is a heavy object from being dropped from the base part 2.

  Then, the construction method of the cable 20 using the elevator cable construction apparatus 1 is demonstrated.

  Referring to FIG. 5, the cable 20 from the elevator cable erection device 1 installed inside the car 108 by the worker (erection worker) 60 located on the car 103 passes through the rescue outlet of the car 108 (not shown). Pulled out to top 103. The worker 60 may move the car 20 to the top 103 after pulling out the cable 20 from the elevator cable laying device 1 inside the car 108.

  Referring to FIG. 6, the car 108 is moved to the top part (uppermost part) of the hoistway 105 in a state where the cable 20 is sent to the car top 103. The cable 20 is fixed by the operator 60 at the top of the hoistway 105 in consideration of the length of the cable 20 installed in the machine room 106.

  The cable 20 installed in the machine room 106 is transferred from the worker 60 located in the hoistway 105 to the worker 60 a located in the machine room 106. The cable 20 is electrically connected to the control panel 102 provided outside the car 108 by the worker 60a. As described above, the operator 60 on the car 103 and the operator 60a of the machine room 106 cooperate to start up the cable 20 in the machine room 106.

  Here, the operation of the elevator cable erection device 1 when the cable 20 is erected as described above will be described.

  Referring to FIG. 7, when operator 60 pulls cable 20 as shown in FIG. 5, rotating drum 5 rotates in the direction of arrow D1 (clockwise direction) in the figure, and cable 20 is pulled out in delivery direction D1. .

  With reference to FIG. 8, in a state where the cable 20 is pulled out in the feeding direction D1, the claw 10a of the locking mechanism 10 moves in the direction of arrow D4 in the drawing according to the shape of the teeth of the gear 10b. As a result, the engagement between the claw 10a and the gear 10b is released, so that the gear 10b rotates in the direction of the arrow D1 in the figure with the lock mechanism 10 unlocked. As the gear 10b rotates in the direction of arrow D1 in the figure, the rotary drum 5 rotates in the direction of arrow D1 in the figure.

  As the rotating drum 5 rotates in the direction of the arrow D1 in the figure, the urging means (spring) 8 is wound. Therefore, the gear 10b of the lock mechanism 10 is urged by the urging means 8 in the direction of arrow D2 (winding direction D2) in the figure. Since the gear 10b is urged by the urging means 8, when the claw 10a moves to the gear 10b side from the state shown in FIG. 8 to the state shown in FIG. 4, as shown in FIG. 10a and gear 10b are engaged.

  Since the teeth of the gear 10b are arranged at a predetermined rotation angle with respect to the rotation center of the gear 10b, the claw 10a and the gear 10b can be engaged at every predetermined rotation angle. By engaging the claw 10a and the gear 10b for each predetermined rotation angle, the cable 20 wound around the rotary drum 5 is sent out from the rotary drum 5 by a predetermined rotation angle. By pulling out the cable 20 at every predetermined rotation angle, the cable 20 can be pulled out by a predetermined length according to the predetermined rotation angle. Therefore, the delivery amount of the cable 20 can be easily adjusted.

  When adjusting the length of the cable 20 that has been pulled out too much, the length of the cable 20 can be adjusted by automatically winding the cable 20 around the rotating drum 5 by the biasing means 8 as follows. . When the delivery amount of the cable 20 is too large, the cable 20 can be wound up by releasing the lock mechanism 10.

  Referring to FIG. 9, first, the cable 20 is slightly pulled out from the rotary drum 5 in the feed direction D1. As shown in FIG. 8, the claw 10a is disengaged from the gear 10b, and the lock mechanism 10 is unlocked. Referring to FIG. 10, when the cable 20 is released with the lock mechanism 10 unlocked, the biasing means 8 causes the gear 10b to move in the direction of arrow D2 before the claw 10a moves toward the gear 10b. Rotate (counterclockwise). For this reason, the nail | claw 10a does not catch on the gearwheel 10b, but the gearwheel 10b continues rotating in the arrow D2 direction in the figure. As the gear 10b continues to rotate in the direction of the arrow D2 in the figure, the rotating drum 5 continues to rotate in the winding direction D2.

  With reference to FIG. 11, the cable 20 is wound around the rotating drum 5 in the winding direction D <b> 2 as the rotating drum 5 continues to rotate in the winding direction D <b> 2. When the movement of the cable 20 is interrupted by grasping the cable 20 while the cable 20 is wound around the rotary drum 5, the claw 10a moves to the gear 10b side. When the cable 20 is released in this state, the claw 10a and the gear 10b are engaged with each other by rotating in the winding direction D2 by a maximum angle of one tooth until the gear 10b is engaged with the claw 10a.

  Thereby, the rotation of the rotating drum 5 can be terminated and the winding of the cable 20 can be terminated. In this way, the winding amount of the cable 20 can be easily adjusted. The cable 20 having a predetermined length can be pulled out from the rotating drum 5 by adjusting the winding amount and the feeding amount of the cable 20 as described above. Thereby, the length of the cable 20 can be adjusted easily.

  If the cable 20 is pulled out excessively, the cable 20 may be entangled by the winding habit of the cable 20 and force may be applied to the cable 20 to cause disconnection. However, the length of the cable 20 that has been pulled out excessively is adjusted as described above. Therefore, disconnection of the cable 20 can be suppressed.

Next, the marking on the cable 20 will be described.
In the present embodiment, the cable 20 may be marked with a predetermined feed amount by the marker 6. Referring to FIGS. 6 and 7, when the cable 20 is installed, the cable 20 is drawn from the rotating drum 5 to the value set by the measuring means 61 of the marker 6 in advance from the length of the hoistway 105 or the like. The marking 11 is provided at a position corresponding to the feed amount of the cable 20 having a predetermined length drawn from the rotary drum 5 by the means 62.

  For example, the cable 20 can be marked with the length of the cable 20 required for the machine room 106. In this case, for example, a numerical value obtained by the following calculation formula is set in a rotary counter (not shown).

(Total length of cable 20) − (Length of hoistway 105 (default)) − (Length of cable 20 from bottom of car to top of car 103) = (Cable length of machine room)
Here, the “length of the hoistway 105” is determined when the building in which the hoistway 105 is installed is constructed, and can be set by information on the drawing. The “cable length from the bottom of the car to the top of the car 103” can be calculated by determining the mounting dimensions to a car hanger (not shown).

  The feed amount of the cable 20 is measured by rotating a roller (not shown) of the measuring means 61. When the numerical value of the feeding amount of the cable 20 preset by a rotary counter (not shown) of the measuring means 61 matches the feeding amount of the cable 20 measured by the measuring means 61, the marking means is positioned at a position corresponding to the feeding amount of the cable 20. Marking 11 is applied by 62.

  The cable 20 having a predetermined length on which the marking 11 is applied with the length of the cable 20 in the machine room 106 is set up in the machine room 106 by adjusting the length of the cable 20 according to the marking 11. At this time, the cable 20 having a predetermined length with the marking 11 is electrically connected to a control panel 102 provided outside the car 108.

  Next, a method of laying the cable 20 up to the lowest floor of the elevator 100 after the cable 20 is started up in the machine room 106 will be described.

  Referring to FIG. 12, after the cable 20 is raised in the machine room 106 as described above, the car 108 is sent to the lowermost floor while the cable 20 is being sent out from the elevator cable erection device 1 installed inside the car 108. Moved to. The operator 60 attaches the cable 20 in the hoistway 105 as appropriate. In this way, the cable 20 is installed up to the lowest floor of the elevator 100.

  Referring to FIG. 13, when the installation of cable 20 in hoistway 105 is completed, cable 20 remaining on base 2 of elevator cable installation apparatus 1 is sent into pit 112. The worker 60 moves into the pit 112. An undercarriage hanger (not shown) is attached in the pit 112 by the worker 60. Note that an existing car hanger (not shown) may be used. An operator 60 attaches the cable 20 to the car hanger.

  Referring to FIG. 14, the worker 60 moves to the car top 103. The cable 20 is electrically connected to the car 108 by an operator 60 located on the car 103. The cable erection work is completed by raising the cable 20 to the car top 103. Thereby, the replacement of all the cables 20 is completed.

Next, the effect of this Embodiment is demonstrated.
According to the elevator cable laying apparatus 1 of the present embodiment, the lock mechanism 10 that can lock the rotation of the rotary drum 5 in the direction D2 for winding up the cable 20 at a predetermined rotation angle is used in accordance with a predetermined rotation angle. The cable 20 can be pulled out by length. Further, the cable 20 can be wound up by the urging means 8 that urges the rotating drum 5 to rotate in the direction D2 in which the cable 20 is wound up in a state where the lock mechanism 10 is unlocked.

  Therefore, adjustment of the winding amount and the sending amount of the cable 20 can be easily performed. Thereby, workability | operativity of construction of the cable 20 can be improved. By improving the workability of installing the cable 20, the installation worker 60 of the cable 20 can replace the cable 20 in a short time. Therefore, the stop time of the elevator 100 for exchanging the cable 20 can be shortened.

  Further, according to the elevator cable laying apparatus 1 of the present embodiment, the lock mechanism includes a claw and a gear capable of engaging the rotary drum 5 against the urging force of the urging means 8 by engaging with the claw. Therefore, the cable 20 can be held at a predetermined length. Therefore, the length of the cable 20 can be easily adjusted.

  Moreover, according to the elevator cable erection device 1 of the present embodiment, the marker 6 for marking the cable 20 is further provided. The marker 6 includes a marking unit 62 that can mark a position corresponding to the cable feed amount when the measurement unit 61 measures a preset feed amount of the cable 20. Thereby, since the length of the cable 20 can be adjusted according to marking, the workability | operativity of construction of the cable 20 can further be improved.
