Description

[Technical field]

[0001] The present invention relates to a template positioning device. [Background technology]

[0002] Elevator hoistways in newly constructed buildings are constructed with precision managed by construction companies. Currently, elevator installation work is carried out in the following steps. First, multiple piano wires are installed vertically from the ceiling of the hoistway. At this time, the piano wires are hung vertically using weights and are installed so that they maintain this vertical state. Next, using the position of the piano wires as the elevator installation reference, guide rails are laid in the hoistway and a sill is installed at the entrance / exit on the hall side. There are guide rails that guide the movement of the elevator car and guide rails that guide the movement of the counterweight (balancing weight). The work of laying the guide rails and installing the sill is carried out by elevator installation workers (hereinafter simply referred to as "workers").

[0003] As described above, when installing each piece of equipment in an elevator, the piano wire, which is the reference for aligning each piece of equipment, is attached to an installation jig called a template and installed vertically in the hoistway. At that time, the worker needs to install the piano wire at a specified position from the reference mark marked by the construction company on the reference floor (usually the first floor). For this reason, the worker first performs marking work from the reference mark and installs a scale so that the specified position can be specified on the reference floor. Next, the worker moves the template so that the position of the piano wire approaches the specified position specified by the scale. Prior to moving the template, the worker installs the template on the ceiling part of the hoistway. In addition, the worker fixes the upper end of the piano wire to the template, attaches a weight to the lower end of the piano wire, and hangs the piano wire from the template. For this reason, in order to move the template, the worker needs to go up to the ceiling part of the hoistway. Next, the worker moves from the ceiling part of the hoistway to the reference floor and checks whether the position of the piano wire is aligned with the specified position. The worker then goes back and forth between the ceiling of the elevator shaft and the reference floor several times, repeatedly moving the template and checking the position of the piano wire, thereby aligning the piano wire to the specified position.

[0004] As a technique for installing a piano wire in an elevator hoistway, for example, Patent Document 1 describes a technique related to "an automatic positioning device for an elevator reference template, comprising: template support members installed at a predetermined interval in the planar direction at the top of the hoistway; a reference template that is installed parallel to the landing side, spanning between the template support members, and has piano wire hanging parts at both ends; X-axis positioning devices that are installed at both ends of the reference template and have built-in motors for independently adjusting and controlling the planar movement of both ends of the reference template in a direction perpendicular to the landing side; a Y-axis positioning device that is installed in the middle of the reference template and has a built-in motor for adjusting and controlling the planar movement of the reference template in a direction parallel to the landing side; a remote control device that can remotely control the X-axis positioning device and the Y-axis positioning device; a piano wire that hangs down from the piano wire hanging parts at both ends of the reference template and has a weight attached to its lower end; and a weight-stilling water container that is installed in the hoistway pit and in which the weight suspended from the lower end of the piano wire is immersed to suppress the pendulum motion of the weight." Furthermore, Patent Document 1 describes a technique related to an "automatic positioning method for an elevator reference template" using the automatic positioning device configured as described above.

[0005] Before a worker can finish installing the piano wire, he or she must go back and forth between the top floor of the building and the reference floor using the stairs multiple times. This places a heavy physical burden on the worker, and the work time required to complete the installation of the piano wire is long. With the technology described in Patent Document 1, a reference template, which corresponds to a template, can be moved remotely using a remote control device. This reduces the physical burden on the worker. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2009-23801 A Summary of the Invention [Problem to be solved by the invention]

[0007] However, the technique described in Patent Document 1 has the following problems. Patent Document 1 describes that a position adjustment mechanism (X-axis direction positioning device and Y-axis direction positioning device) for adjusting the position of a reference template is set on the reference template, and the reference template is attached to two support members (template support members). In this case, when the reference template is fixed to the support members, it cannot be moved. Therefore, in order to adjust the position of the reference template by the operation of the position adjustment mechanism, it is necessary to attach the position adjustment mechanism to the support members and attach the reference template to the movable part of this position adjustment mechanism. Therefore, it is necessary to attach the position adjustment mechanism to the support members until the installation of each device of the elevator is completed based on the position of the piano wire. Therefore, when the installation work of the elevator equipment is carried out in parallel at multiple sites, it is necessary to prepare position adjustment mechanisms for the number of work sites.

[0008] An object of the present invention is to provide a template positioning device that can adjust the position of a template supported by a support member using a position adjustment mechanism, and then remove the position adjustment mechanism from the support member while maintaining the adjusted position of the template. [Means for solving the problem]

[0009] In order to solve the above problems, for example, the configurations described in the claims are adopted. The present application includes a number of means for solving the above problems. One of the means is a template positioning device that positions a template supported by a number of support members installed in an elevator shaft and to which an upper end of a piano wire is attached, the device comprising: The plurality of support members are installed horizontally and parallel to each other, and each support member is attached to one wall and another wall facing the one wall among four walls excluding the ceiling and floor of the elevator shaft; The apparatus includes a position adjustment mechanism that adjusts the position of the template, a stand that supports the position adjustment mechanism and is detachably attached to the support member, and a fixing device that fixes the template, the position of which has been adjusted by the position adjustment mechanism, to the support member. Effect of the Invention

[0010] According to the present invention, after the position of the template supported by the support member is adjusted by the position adjustment mechanism, the position adjustment mechanism can be removed from the support member while maintaining the adjusted state of the template. Problems, configurations and effects other than those described above will become apparent from the following description of the embodiments. [Brief description of the drawings]

[0012] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In this specification and the drawings, elements having substantially the same functions or configurations are given the same reference numerals, and duplicated descriptions are omitted. Each reference drawing shows a schematic configuration of an apparatus according to an embodiment. For this reason, in the reference drawings, the scale, intervals, positional relationships, etc. of each member may be exaggerated, or some of the members may be omitted.

[0013] FIG. 1 is a plan view showing a configuration example of a template, and FIG. 2 is a view of the template shown in FIG. 1 as viewed from a direction A. As shown in FIG. As shown in Figs. 1 and 2, the template 1 is an elongated member that is C-shaped downward when viewed from the direction A. The template 1 integrally has one flat plate portion 2 and two side plate portions 3 and 4. The side plate portion 3 is bent at a right angle from one long side of the flat plate portion 2, and the side plate portion 4 is bent at a right angle from the other long side of the flat plate portion 2. The two side plate portions 3 and 4 are arranged in pairs on the left and right when viewed from the direction A. In addition, the side plate portion 3 is formed in an L shape when viewed from the direction A, and the side plate portion 4 is formed in an inverted L shape when viewed from the direction A.

[0014] A protrusion 5 is provided at each of one end and the other end in the longitudinal direction of the template 1. The protrusion 5 is fixed to the flat plate portion 2 of the template 1. The protrusion 5 has a male screw 5a. As shown in FIG. 2, the male screw 5a of the protrusion 5 protrudes to the opposite side to the side plate portions 3 and 4 in the thickness direction of the flat plate portion 2. The protrusion 5 is also formed with a through hole 5b penetrating the central axis of the protrusion 5. The upper end of the piano wire 7 is attached to the protrusion 5 through the through hole 5b. The protrusions 5 are provided at both ends of the template 1. Therefore, two (two) piano wires 7 are attached to one template 1.

[0015] First Embodiment Fig. 3 is a schematic side view showing a state in which the template positioning device according to the first embodiment is installed in an elevator hoistway. Fig. 4 is a plan view showing an example of the configuration of the template positioning device according to the first embodiment. Fig. 5 is a view of the template positioning device shown in Fig. 4 as seen obliquely from above, and Fig. 6 is a view of the template positioning device shown in Fig. 4 as seen obliquely from below. In this embodiment, in order to clarify the shape and positional relationship of each part, the left-right direction is defined as the X direction, the depth direction is defined as the Y direction, and the up-down direction (vertical direction) is defined as the Z direction, based on the case where an operator stands in the elevator hall and looks at the elevator entrance from the front. The X direction, Y direction, and Z direction are mutually perpendicular. The X direction corresponds to the first direction, and the Y direction corresponds to the second direction.

[0016] As shown in Fig. 3, a template positioning device (hereinafter also simply referred to as "positioning device") 10 is a device that includes a position adjustment mechanism, which will be described later, and positions the template 1 using this position adjustment mechanism. The positioning device 10 is attached to the ceiling portion (top) of an elevator shaft 11 when in use. The positioning of the template 1 is performed to align the position of a piano wire 7 suspended from the template 1 by means of a weight 6 to a predetermined position.

[0017] In a building under construction, a work platform 12 is installed on the top floor of the elevator shaft 11. The work platform 12 is also called the top stage. A worker 13 stands on the work platform 12 and performs a predetermined task. The predetermined tasks include the installation of the positioning device 10, the installation of the template 1, and the installation of the piano wire 7. A curtain 14 is installed at the entrance of each floor of the elevator shaft 11 to ensure the safety of the worker 13. In addition, two support pipes 15 are installed on the ceiling of the elevator shaft 11 as an example of a support member. The two support pipes 15 are arranged parallel to each other. In addition, each support pipe 15 is installed horizontally using a level not shown. It is sufficient that the parallelism and horizontality of the two support pipes 15 are ensured to a degree of accuracy that does not cause any trouble when positioning the template 1 using the positioning device 10. In addition, the number of support pipes 15 is not limited to two, and may be three or more.

[0018] Each support pipe 15 is formed in a cylindrical shape. One end of the support pipe 15 is a screw-type telescopic part 15a. The telescopic part 15a changes the overall length of the support pipe 15 by telescopically extending in the direction of the central axis of the support pipe 15. An operating lever 16 and an abutment plate 17 are provided at one end of the support pipe 15. The operating lever 16 is provided so as to be rotatable around the central axis of the support pipe 15. The telescopic part 15a extends when the operating lever 16 is rotated in one direction, and contracts when the operating lever 16 is rotated in the opposite direction. The abutment plate 17 abuts against the wall 11b of the elevator shaft 11.

[0019] The support pipe 15 having the above configuration is fixed by using two walls 11a and 11b facing each other in the Y direction among the four walls excluding the ceiling and floor of the elevator shaft 11. Specifically, a plate 18 (see FIG. 7) provided at one end of the support pipe 15 is abutted against the wall 11a, and an abutment plate 17 provided at the other end of the support pipe 15 is abutted against the wall 11b by rotating the operation lever 16. At that time, the abutment plate 17 is strongly pressed against the wall 11b by rotating the operation lever 16 in the direction in which the extension part 15a extends. This allows the support pipe 15 to be fixed to the ceiling part of the elevator shaft 11. In addition, the two support pipes 15 can be installed parallel and horizontally by using a spirit level, a tape measure, or the like (not shown).

[0020] The template 1 and the positioning device 10 are attached onto the two support pipes 15 thus installed.

[0021] Here, the configuration of the positioning device 10 will be described with reference to FIGS. The positioning device 10 includes position adjustment mechanisms 21, 22 that adjust the position of the template 1, a stand 24 that supports the position adjustment mechanisms 21, 22, and a fixture 25 (Figure 4) that fixes the template 1 after its position has been adjusted to two support pipes 15.

[0022] The position adjustment mechanism 21 is a mechanism for adjusting the position of the template 1 in the X direction. The position adjustment mechanism 21 corresponds to a first position adjustment mechanism. The position adjustment mechanism 21 includes a linear actuator 31 having a fixed part 31a and a movable part 31b, a bracket 32 ​​fixed to the tip of the movable part 31b, and a gripping stay 33 attached to the lower surface of the bracket 32 ​​by screwing. The fixed part 31a is fixed to the lower surface of a connecting base 36 described later. The fixed part 31a includes a drive source (not shown) for moving the movable part 31b and a power transmission mechanism (not shown) for transmitting the driving force of the drive source to the movable part 31b. The movable part 31b reciprocates in the X direction by the driving force of the drive source built into the fixed part 31a. The bracket 32 ​​moves in the X direction together with the movable part 31b. The gripping stay 33 is a member for gripping the template 1 between the bracket 32 ​​and the gripping stay 33. The gripping stay 33 is formed in a hat shape.

[0023] In the position adjustment mechanism 21 configured as above, the template 1 moves in the X direction together with the movable part 31b by moving the movable part 31b of the linear actuator 31 while the template 1 is held by the holding stays 33. Therefore, the position of the template 1 in the X direction can be adjusted by the operation of the linear actuator 31.

[0024] The position adjustment mechanism 22 is a mechanism for adjusting the position of the template 1 in the Y direction. The position adjustment mechanism 22 is also a mechanism for adjusting the inclination of the template 1 with respect to the X direction. That is, the position adjustment mechanism 22 constitutes a second position adjustment mechanism and a third position adjustment mechanism. The position adjustment mechanism 22 includes two linear actuators 35, a connecting base 36, and two guide plates 37. The two linear actuators 35 are arranged at an interval in the X direction. The two linear actuators 35 correspond to a pair of actuators. Each linear actuator 35 has a fixed part 35a and a movable part 35b. The fixed part 35a is fixed to the stand 24. The fixed part 35a includes a drive source (not shown) for moving the movable part 35b and a power transmission mechanism (not shown) for transmitting the drive force of the drive source to the movable part 35b. The movable part 35b reciprocates in the Y direction by the drive force of the drive source built in the fixed part 35a. A connecting pin 38 is attached to the tip of the movable portion 35b. The connecting pin 38 is disposed facing vertically upward.

[0025] The connecting base 36 is formed in a long plate shape. The connecting base 36 connects the movable parts 35b of the two linear actuators 35 to each other. The connecting base 36 corresponds to a connecting member. The connecting base 36 is provided with a round hole 36a and a long hole 36b. The long hole 36b is a hole whose long axis direction is the longitudinal direction of the connecting base 36. The center-to-center distance between the round hole 36a and the long hole 36b in the longitudinal direction of the connecting base 36 is set to be equal to the interval between the two linear actuators 35 in the X direction. One connecting pin 38 is inserted into the round hole 36a, and the other connecting pin 38 is inserted into the long hole 36b.

[0026] The two guide plates 37 are attached to the connecting base 36 with a gap therebetween in the X direction. Specifically, each guide plate 37 is attached to the lower surface of the connecting base 36 via a pedestal 39. The pedestal 39 is provided with a through hole (not shown) for allowing the connecting pin 38 to protrude upward beyond the connecting base 36. The guide plate 37 is formed in a gate shape when viewed from the X direction. The guide plate 37 clamps the template 1 in the Y direction. The two guide plates 37 correspond to a pair of clamping members.

[0027] In the position adjustment mechanism 22 having the above configuration, the template 1 is moved in the Y direction together with the connecting base 36 by moving the movable parts 35b of the two linear actuators 35 by the same amount in the same direction while the template 1 is sandwiched between the two guide plates 37. In addition, the template 1 is tilted in the Y direction together with the connecting base 36 by moving the movable parts 35b of the two linear actuators 35 in different directions and / or by different amounts while the template 1 is sandwiched between the two guide plates 37. At that time, when the movable parts 35b of the two linear actuators 35 are moved by the same amount in different directions, the template 1 rotates in a horizontal plane around the center position between the two guide plates 37. That is, the posture of the template 1 changes in the horizontal plane. In addition, the two linear actuators 35 and the connecting base 36 are connected by two connecting pins 38, and each connecting pin 38 is inserted into the corresponding round hole 36a and long hole 36b. Therefore, the connecting base 36 tilts in the Y direction around the connecting pin 38 inserted in the round hole 36a, and this tilt of the connecting base 36 is permitted by the engagement of the connecting pin 38 with the long hole 36b. Therefore, by operating the two linear actuators 35, the position of the template 1 can be adjusted in the Y direction, and the tilt of the template 1 with respect to the X direction can be adjusted.

[0028] The frame 24 is detachably attached to the two support pipes 15. The frame 24 includes two base plates 41, two erection beams 42, and two connecting beams 43. The two base plates 41 are arranged at an interval in the X direction. The base plate 41 is formed in a flat plate shape. The base plate 41 is fixedly attached to the upper peripheral surface of the support pipe 15 using bolts (not shown). Therefore, the base plate 41 can be removed from the support pipe 15 by loosening and removing the bolts.

[0029] The two erection beams 42 are arranged spanning the two support pipes 15. The two erection beams 42 are also arranged parallel to the X direction. Each erection beam 42 is placed on the upper surface of the two base plates 41 and fixed to the base plates 41 in this state by bolts or the like (not shown).

[0030] The two connecting beams 43 are beams that connect the two erection beams 42. One end of the connecting beam 43 is fixed to one erection beam 42, and the other end of the connecting beam 43 is fixed to the other erection beam 42. The two connecting beams 43 are arranged with an interval in the X direction. The two connecting beams 43 are arranged on the inside of the two base plates 41 in the X direction. The two connecting beams 43 are also arranged parallel to the Y direction.

[0031] The two erection beams 42 and the two connection beams 43 described above form an H-shaped beam in plan view, and the two linear actuators 35 are mounted on this beam. Specifically, the linear actuators 35 are placed on the connection beams 43 and fixed to the erection beams 42 in that state.

[0032] The number of the erection beams 42 is not limited to two, but may be three or more. The same applies to the connection beams 43. Also, the pair of linear actuators 35 can be implemented using only two installation beams 42. That is, the connecting beam 43 may be provided as necessary. When the connecting beam 43 is provided, the mechanical strength of the frame 24 can be increased. Therefore, vibrations and the like that occur when each linear actuator 35 is operated can be suppressed.

[0033] Two fixtures 25 are provided to fix one template 1 to two support pipes 15. The fixtures 25 are arranged at positions different from the base plate 41 in the longitudinal direction (Y direction) of the support pipes 15. The fixtures 25 are fixed to the upper peripheral surface of the support pipes 15 using a clamp (not shown). As the clamp, a C-shaped clamp that can be fixed to a single pipe by tightening a bolt can be used.

[0034] As shown in FIG. 7, the fixing device 25 includes a receiving portion 45 that receives and supports the template 1, two clamp portions 46 facing each other, two nut members 47 fixed to the outer surface of each clamp portion 46, and two clamp bolts 48 that engage with the nut members 47.

[0035] The receiving portion 45 has a support surface 45a that supports the template 1 movably within a horizontal plane. The support surface 45a is formed in a rectangular shape in a plan view. The support surface 45a is disposed facing upward. The two clamp portions 46 stand vertically from two corresponding sides of the receiving portion 45. Therefore, when the fixing device 25 is viewed from the X direction, the receiving portion 45 and the two clamp portions 46 form a U-shape. The receiving portion 45 and the two clamp portions 46 are preferably of an integral structure.

[0036] The nut member 47 is fixed to the outer surface of the clamp portion 46 by welding or the like. The nut member 47 has a female thread (not shown). The clamp portion 46 is formed with a through hole (not shown) having a diameter larger than the female thread of the nut member 47. The female thread of the nut member 47 is arranged coaxially with the through hole of the clamp portion 46.

[0037] The clamp bolt 48 has a male thread 48a that meshes with the female thread of the nut member 47. The male thread 48a is inserted into the through hole of the clamp part 46 while meshing with the female thread of the nut member 47. A tip 48b of the clamp bolt 48 (male thread 48a) protrudes above the support surface 45a through the through hole of the clamp part 46. The two clamp bolts 48 are disposed facing each other on an imaginary axis parallel to the Y direction.

[0038] In the fixture 25 having the above configuration, when the clamp bolt 48 is rotated, the position of the clamp bolt 48 moves in the Y direction due to the engagement between the female thread and the male thread 48a of the nut member 47. At this time, the direction and amount of movement of the clamp bolt 48 in the Y direction are determined by the direction and amount of rotation of the clamp bolt 48. Therefore, the protruding dimension of the tip portion 48b of the clamp bolt 48 on the support surface 45a can be arbitrarily adjusted by rotating the clamp bolt 48. Also, as shown in FIG. 7, in a state in which the template 1 is placed and supported on the support surface 45a of the receiving portion 45, the tip portions 48b of the two clamp bolts 48 are disposed in a state spaced apart from the corresponding side plate portions 3, 4 (see FIG. 1) of the template 1, so that the movement of the template 1 in the horizontal direction is not restricted. Therefore, the template 1 is supported by the support surface 45a so as to be movable in the horizontal direction. In contrast, when the template 1 supported on the support surface 45a is sandwiched from both sides in the Y direction by the two clamp bolts 48, the movement of the template 1 in the horizontal direction is restricted. In other words, the template 1 is fixed to the fixture 25 by the two clamp bolts 48, and is fixed to the support pipe 15 via the fixture 25.

[0039] FIG. 8 is a block diagram showing a control configuration of the template positioning device according to the first embodiment. As shown in FIG. 8, the positioning device 10 includes a remote controller (hereinafter also referred to as "remote control") 50 and a control device 52 that exchanges signals with the remote control 50. The remote control 50 has an antenna 50a for wireless communication. The control device 52 has an antenna 52a for wireless communication. As shown in FIG. 3, the remote control 50 is a device used by an operator 13 who checks the position of the piano wire 7 on a reference floor of a building (the first floor in the illustrated example). The remote control 50 corresponds to an operating device that remotely operates the position adjustment mechanisms 21, 22 described above.

[0040] The control device 52 is a device that individually controls the linear actuator 31 and the pair of linear actuators 35. The control device 52 is placed and fixed on two erection beams 42, for example, as shown in Fig. 4. The control device 52 receives a signal transmitted from the remote control 50, and controls the operation of the linear actuators 31, 35 in response to the received signal.

[0041] FIG. 9 is an external view showing an example of the remote controller according to the first embodiment. As shown in FIG. 9, the remote control 50 is provided with a display unit 510, a power button 520, a reset button 530, a storage position button 540, two left / right movement buttons 550, and four forward / backward movement buttons 560.

[0042] The display unit 510 displays information referred to by the operator 13 when remotely operating the position adjustment mechanisms 21, 22 using the remote control 50. Examples of information referred to by the operator 13 include the amount of movement when the template 1 is moved in the X direction by the operation of the linear actuator 31, the amount of movement when the template 1 is moved in the Y direction by the operation of one linear actuator 35, and the amount of movement when the template 1 is moved in the Y direction by the operation of the other linear actuator 35. The power button 520 is a button for turning on and off the power of the control device 52 and each linear actuator 31, 35. The reset button 530 is a button for resetting the amount of movement displayed on the display unit 510 for each linear actuator 31, 35 to zero. The storage posture button 540 is a button for reducing the position adjustment mechanisms 21, 22 in a state where they are removed from the support pipe 15 together with the stand 24 (the state shown in FIG. 4) to a size suitable for storage. When the stored position button 540 is pressed, the movable parts 31b, 35b of the respective linear actuators 31, 35 are brought to their most retracted states.

[0043] The two left / right direction movement buttons 550 are buttons for moving the template 1 in one direction or the other in the X direction by the operation of the linear actuator 31. Of the two left / right direction movement buttons 550, when the left left / right direction movement button 550 is pressed, the two piano wires 7 move to the left as viewed by the worker 13 on the reference floor, and when the right left / right direction movement button 550 is pressed, the two piano wires 7 move to the right.

[0044] The four forward / rearward direction movement buttons 560 are buttons for moving the template 1 in the Y direction or tilting the template 1 with respect to the X direction by the operation of the pair of linear actuators 35. When the upper two forward / rearward direction movement buttons 560 of the four forward / rearward direction movement buttons 560 are pressed simultaneously, the two piano wires 7 move to the rear side as viewed by the worker 13 on the reference floor, and when the lower two forward / rearward direction movement buttons 560 are pressed simultaneously, the two piano wires 7 move to the front side. When only the upper right forward / rearward direction movement button 560 is pressed, the right piano wire 7 moves to the rear side as viewed by the worker 13 on the reference floor, and when only the upper left forward / rearward direction movement button 560 is pressed, the left piano wire 7 moves to the rear side. When only the lower right forward / rearward direction movement button 560 is pressed, the right piano wire 7 moves to the front side as viewed by the worker 13 on the reference floor, and when only the lower left forward / rearward direction movement button 560 is pressed, the left piano wire 7 moves to the front side.

[0045] 10 is a flow chart showing the procedure for installing a piano wire using the positioning device according to the first embodiment. The procedure below is performed by a worker 13. The number of workers 13 may be one or more depending on the content of the installation work, but the number of workers 13 will be omitted in the following explanation.

[0046] First, the worker 13 sets up the work platform 12 at the top of the elevator shaft 11 (step S101). Next, the worker 13 stands on the workbench 12 and installs the two support pipes 15 (step S102). Next, the worker 13 attaches the fasteners 25 to the respective support pipes 15 as shown in FIG. 7 (step S103). Next, the worker 13 places the template 1 on the two fixtures 25 (step S104).

[0047] Next, the worker 13 attaches the positioning device 10 to the two support pipes 15 (step S105). At this time, the worker 13 has previously assembled the positioning device 10. An example of a procedure for assembling the positioning device 10 will be described below.

[0048] First, the worker 13 assembles the two erection beams 42 and the two connection beams 43 into an H-shape in plan view. Next, the worker 13 places the two erection beams 42 on the two base plates 41 and fixes them. Next, the worker 13 attaches a pair of linear actuators 35 to the two erection beams 42 . Next, the worker 13 connects the movable parts 35b of the pair of linear actuators 35 with the connecting base 36. Specifically, the connecting pin 38 provided at the tip of the movable part 35b of one linear actuator 35 is inserted into the round hole 36a of the connecting base 36, and the connecting pin 38 provided at the tip of the movable part 35b of the other linear actuator 35 is inserted into the long hole 36b of the connecting base 36.

[0049] Next, the worker 13 attaches the linear actuator 31 to the lower surface of the connecting base 36 , and also attaches the bracket 32 ​​to the tip of the movable part 31 b of the linear actuator 31 . Next, the worker 13 attaches the guide plate 37 to the lower surface of the connecting base 36 via the pedestal 39 . Next, the worker 13 attaches the grip stay 33 to the bracket 32 ​​attached to the tip of the movable part 31 b of the linear actuator 31 . This completes the assembly of the positioning device 10.

[0050] In the above step S105, when attaching the positioning device 10 to the two support pipes 15, the worker 13 first places the base plate 41 on each of the two support pipes 15. At this time, the worker 13 places the two guide plates 37 over the template 1, respectively. The worker 13 also fixes the holding stay 33 to the bracket 32 ​​by screwing, so as to sandwich the template 1 between the bracket 32 ​​and the holding stay 33. Next, the worker 13 fixes the two base plates 41 to the corresponding support pipes 15 with bolts (not shown).

[0051] Thereafter, the worker 13 attaches the piano wire 7 and the weight 6 (step S106). At this time, the worker 13 passes the piano wire 7 through the through hole 5b of the protrusion 5 provided on the template 1, and wraps and fixes one end (upper end) of the piano wire 7 around the protrusion 5. The worker 13 also wraps and fixes the other end (lower end) of the piano wire 7 around the hook 6a of the weight 6, as shown in FIG. Next, the worker 13 gets off the work platform 12, moves from the top floor of the elevator shaft 11 to the reference floor, and sets up the scale 60 on the reference floor (step S107). At this time, the worker 13 performs marking work using a reference marking that has been marked in advance by the construction company on the reference floor of the elevator shaft 11, and sets up the scale 60 so that a predetermined position on the reference floor can be identified. The worker 13 also fixes the scale 60 to the floor surface of the reference floor so that the corner of the scale 60 is at a predetermined position. The predetermined position is the target position to which the piano wire 7 should be aligned.

[0052] Next, the worker 13 checks the deviation between the predetermined position and the position of the piano wire 7, and operates the buttons (left-right movement button 550, front-back movement button 560) of the remote control 50 so as to reduce this deviation (step S108). At this time, the worker 13 checks the position deviation of the piano wire 7 using a handheld scale (not shown) prepared separately from the scale 60. The worker 13 also operates the two left-right movement buttons 550 and the four front-back movement buttons 560 as appropriate according to the magnitude of the deviation between the predetermined position and the position of the piano wire 7, and the direction of the deviation. As a result, the template 1 and the piano wire 7 move according to the operation of the linear actuators 31 and 35. At this time, the worker 13 operates the remote control 50 at the reference floor of the elevator 11, and therefore does not need to move to the top floor to move the template 1. This reduces the physical burden on the worker.

[0053] Next, when the operator 13 has moved the template 1 by operating the remote control 50 as described above, the operator 13 checks whether the positional deviation of the piano wire 7 has been eliminated by the movement of the template 1 (step S109). When the operator 13 determines that the positional deviation of the piano wire 7 has not been eliminated, that is, that the piano wire 7 is deviated from the predetermined position, the operator 13 returns to the above step S108 and operates the remote control 50 again. When the operator 13 determines that the positional deviation of the piano wire 7 has been eliminated, that is, that the position of the piano wire 7 coincides with the predetermined position, the operator 13 proceeds to the procedure of step S110. The adjustment of the position of the template 1 by the position adjustment mechanisms 21 and 22 is completed at the point when the operator 13 determines in step S109 that the positional deviation of the piano wire 7 has been eliminated. As a result, the template 1 is positioned so that the position of the piano wire 7 coincides with the predetermined position.

[0054] Next, in step S110, the worker 13 moves from the reference floor of the elevator shaft 11 to the top floor, gets on the work platform 12, and fixes the template 1. At this time, the worker 13 fixes the template 1 to the support pipe 15 using the fixtures 25 attached to the support pipe 15 in step S103. Specifically, in each fixture 25, the two clamp bolts 48 are rotated so that the tip portions 48b of each clamp bolt 48 are abutted against the template 1, and each clamp bolt 48 is tightened to fix the template 1 to the two fixtures 25 using a total of four clamp bolts 48. As a result, the template 1 is fixed to the two support pipes 15 via the two fixtures 25.

[0055] Next, the worker 13 removes the positioning device 10 from the two support pipes 15 while leaving the two fasteners 25 attached to the corresponding support pipes 15 (step S111). Specifically, the worker 13 removes the holding stays 33 from the brackets 32 and removes the bolts that fasten the base plate 41 to the support pipes 15, and then lifts up the positioning device 10. This makes it possible to remove the positioning device 10 from the support pipes 15 except for the two fasteners 25.

[0056] Thereafter, the worker 13 gets off the work platform 12, moves from the top floor of the hoistway 11 to the reference floor, and installs the lower template 62 at the bottom (pit) of the hoistway 11 (step S112). At this time, the worker 13 fixes two lower template support pipes 64 to the wall of the hoistway 11 with a gap between them in the X direction, and places and fixes the lower template 62 on these two lower template support pipes 64. The worker 13 also places the lower template 62 and the lower template support pipe 64 between the scale 60 and the weight 6 in the Z direction.

[0057] Next, the worker 13 attaches the piano wire 7 to the lower template 62 (step S113). The lower template 62 is formed in a long shape like the template 1. The lower template 62 is provided with two piano wire fastening parts (not shown) at the same interval as the two protrusions 5 provided on the template 1, and the piano wires 7 are fastened to each of the piano wire fastening parts. In this way, the piano wire 7 is vertically installed between the upper template 1 and the lower template 62. In addition, in the technology described in the above Patent Document 1, it is necessary to prepare a container containing water for stopping the weight in order to suppress the pendulum motion of the weight attached to the lower end of the piano wire, but by attaching the piano wire 7 to the lower template 62 as described above, it is not necessary to prepare such a container.

[0058] As described above, in the positioning device 10 according to the first embodiment, after the position of the template 1 is adjusted by the position adjustment mechanisms 21 and 22, the template 1 is fixed to the two support pipes 15 using the two fixing devices 25, so that the position adjustment mechanisms 21 and 22 and the pedestal 24 can be removed from the support pipes 15 while maintaining the adjusted position of the template 1. Therefore, when elevator equipment installation work is carried out in parallel at multiple work sites, it is sufficient to prepare only two fixing devices 25 for one work site. In addition, the position adjustment mechanisms 21 and 22 removed at one work site can be carried to another work site and used. Therefore, it is not necessary to prepare the position adjustment mechanisms 21 and 22 for the number of work sites. Therefore, the number of equipment used for positioning the template 1 can be reduced.

[0059] Moreover, in the first embodiment, a position adjustment mechanism 21 that adjusts the position of the template 1 in the X direction, and a position adjustment mechanism 22 that adjusts the position of the template 1 in the Y direction and adjusts the inclination of the template 1 with respect to the X direction are provided. This allows for a higher degree of freedom in adjusting the position of the template 1 compared to a case in which the position of the template 1 is adjusted only in two directions, the X direction and the Y direction. This makes it easier to adjust the position of the template 1. Also, it becomes possible to shorten the time required to adjust the position of the template 1.

[0060] Moreover, in the first embodiment, the position adjustment mechanism 22 includes a pair of linear actuators 35 each having a movable part 35b. The position adjustment mechanism 22 adjusts the position of the template 1 in the Y direction by moving each movable part 35b of the pair of linear actuators 35 by the same amount in the same direction, and adjusts the inclination of the template 1 with respect to the X direction by moving each movable part 35b of the pair of linear actuators 35 in different directions and / or by different amounts. This allows the position adjustment mechanism 22 including the pair of linear actuators 35 to operate as a second position adjustment mechanism or a third position adjustment mechanism.

[0061] Moreover, in the first embodiment, the position adjustment mechanism 22 further includes a connecting base 36 that connects the movable parts 35b of the pair of linear actuators 35 to each other, and a pair of guide plates 37 that are attached to the connecting base 36 with a gap therebetween in the X direction and that sandwich the template 1 in the Y direction. With this, with the template 1 sandwiched between the pair of guide plates 37, it is possible to move the template 1 together with the connecting base 36 by appropriately changing the direction and amount of movement of each of the movable parts 35b of the pair of linear actuators 35.

[0062] Moreover, in the first embodiment, the frame 24 includes two base plates 41 that are detachably attached to the two support pipes 15, respectively, and two installation beams 42 that are fixed to the two base plates 41 while spanning the two support pipes 15. Also, the pair of linear actuators 35 are mounted on the two installation beams 42. This reduces the weight of the frame 24 that supports the position adjustment mechanisms 21, 22, and makes it possible to reduce the weight of the positioning device 10.

[0063] Moreover, in the first embodiment, the position adjustment mechanism 21 is located between a pair of guide plates 37 and attached to the connecting base 36. Furthermore, the pair of guide plates 37 guide the movement of the template 1 when the position adjustment mechanism 21 adjusts the position of the template 1 in the X direction. This makes it possible to adjust the position of the template 1 in the X direction without affecting the position adjustment of the template 1 in the Y direction.

[0064] <Second embodiment> FIG. 11 is a plan view illustrating an example of the configuration of a template positioning device according to the second embodiment. A template positioning device 10A according to the second embodiment (hereinafter also simply referred to as the "positioning device") includes a position adjustment mechanism 71 that adjusts the position of the template 1, a stand 72 that supports the position adjustment mechanism 71, and a fixture 25 that fixes the template 1 after its position has been adjusted to two support pipes 15. The support pipes 15 and the fixture 25 are similar to those in the first embodiment, and therefore a description thereof will be omitted.

[0065] The stand 72 is detachably attached to the two support pipes 15. The stand 72 includes a base member 72a arranged across the two support pipes 15, and a plurality of C-shaped clamps (not shown) arranged on the underside of the base member 72a. The base member 72a is formed in a rectangular shape in a plan view and in a flat plate shape. The base member 72a can be fixed to the support pipe 15 by tightening the C-shaped clamps fitted to the support pipe 15 with bolts (not shown). The base member 72a can be removed from the support pipe 15 together with the C-shaped clamps by loosening the bolts tightening the C-shaped clamps.

[0066] The position adjustment mechanism 71 includes a linear actuator 75 and a linear guide 76 attached to a base member 72a of a stand 72, a linear actuator 77 attached to the base member 72a of the stand 72 via the linear guide 76, and a rotation stage 78 attached to the tip of the linear actuator 77. Of these, the linear actuator 75 and the linear guide 76 correspond to a first position adjustment mechanism that adjusts the position of the template 1 in the X direction. The linear actuator 77 corresponds to a second position adjustment mechanism that adjusts the position of the template 1 in the Y direction. The rotation stage 78 corresponds to a third adjustment mechanism that adjusts the inclination of the template 1 with respect to the X direction.

[0067] The linear actuator 75 has a fixed part 75a and a movable part 75b. The fixed part 75a is fixed to the base member 72a. A drive source (not shown) for moving the movable part 75b and a power transmission mechanism (not shown) for transmitting the drive force of the drive source to the movable part 75b are built in the fixed part 75a. The movable part 75b reciprocates in the X direction by the drive force of the drive source built in the fixed part 75a. A connecting member 80 is attached to the tip of the movable part 75b. The connecting member 80 moves in the X direction together with the movable part 75b.

[0068] The linear motion guide 76 includes a fixed base 76a fixed to the base member 72a of the stand 72, a pair of guide shafts 76b arranged on the upper surface side of the fixed base 76a, and a slider 76c movably supported by the pair of guide shafts 76b. The pair of guide shafts 76b are shafts that guide the movement of the slider 76c. The pair of guide shafts 76b are arranged parallel to the X direction. Therefore, the slider 76c is supported by the pair of guide shafts 76b movably in the X direction.

[0069] The linear actuator 77 has a fixed part 77a and a movable part 77b. The fixed part 77a is fixed to the slider 76c of the linear actuator guide 76. A connecting member 80 is attached to the fixed part 77a. The connecting member 80 is a member that connects the movable part 75b of the linear actuator 75 and the fixed part 77a of the linear actuator 77. The fixed part 77a has a built-in drive source (not shown) for moving the movable part 77b and a power transmission mechanism (not shown) that transmits the drive force of the drive source to the movable part 77b. The movable part 77b reciprocates in the Y direction by the drive force of the drive source built in the fixed part 77a.

[0070] The rotating stage 78 has a gripping portion (described later) for gripping the template 1, and rotates the template 1 gripped by the gripping portion in a horizontal plane to adjust the inclination of the template 1 with respect to the X direction. As in the first embodiment, the linear actuator 75, the linear actuator 77, and the rotating stage 78 are each configured to receive a signal transmitted from a remote controller by a control device and to be controlled by the control device in response to the received signal. The control device can be attached onto the base member 72a.

[0071] FIG. 12 is a cross-sectional view showing an example of the configuration of a rotation stage according to the second embodiment. 12, the rotation stage 78 includes a stage body 78a incorporating a drive source and a drive mechanism for rotation, a holder member 78b disposed on the underside of the stage body 78a, and a total of four fixing screws 78c (only two are shown in FIG. 12) attached to the holder member 78b. Of these, the holder member 78b and the four fixing screws 78c form a gripping portion that grips the template 1.

[0072] The holder member 78b rotates about the central axis C of the rotation stage 78 by the operation of the drive source and drive mechanism built into the stage main body 78a. The holder member 78b is formed in an inverted U-shape. The holder member 78b is placed over the template 1. The four fixing screws 78c grip the template 1 by sandwiching it from both sides in the Y direction.

[0073] In the position adjustment mechanism 71 configured as described above, the template 1 is covered with the holder member 78b of the rotation stage 78, and the template 1 is gripped by four fixing screws 78c, thereby fixing the template 1 to the holder member 78b. When the rotation stage 78 is driven in this state, the template 1 rotates together with the holder member 78b. Therefore, the tilt of the template 1 with respect to the X direction can be adjusted by the operation of the rotation stage 78.

[0074] Furthermore, when the movable part 75b of the linear actuator 75 is moved, the linear actuator 77 is guided by the linear guide 76 and moves in the X direction. At this time, the rotation stage 78 attached to the movable part 77b of the linear actuator 77 also moves in the X direction together with the linear actuator 77. Therefore, the position of the template 1 can be adjusted in the X direction by the operation of the linear actuator 75. Furthermore, when the movable part 77b of the linear actuator 77 is moved, the rotation stage 78 moves in the Y direction together with the movable part 77b. Therefore, the position of the template 1 can be adjusted in the Y direction by the operation of the linear actuator 77.

[0075] In the positioning device 10A according to the second embodiment, after the position of the template 1 is adjusted by the position adjustment mechanism 71, the template 1 is fixed to the two support pipes 15 using the two fixing devices 25, so that the position adjustment mechanism 71 and the platform 72 can be removed from the support pipes 15 while maintaining the adjusted position of the template 1. Therefore, when elevator equipment installation work is carried out in parallel at multiple work sites, it is sufficient to prepare only two fixing devices 25 for one work site. In addition, the position adjustment mechanism 71 removed at one work site can be carried to another work site and used. Therefore, it is not necessary to prepare the same number of position adjustment mechanisms 71 as the number of work sites. Therefore, the number of equipment used for positioning the template 1 can be reduced.

[0076] Moreover, the second embodiment includes a linear actuator 75 that adjusts the position of the template 1 in the X direction, a linear actuator 77 that adjusts the position of the template 1 in the Y direction, and a rotation stage 78 that adjusts the inclination of the template 1 with respect to the X direction. This increases the degree of freedom in adjusting the position of the template 1 compared to a case in which the position of the template 1 is adjusted only in two directions, the X direction and the Y direction. This makes it easier to adjust the position of the template 1. Also, it becomes possible to shorten the time required to adjust the position of the template 1.

[0077] Moreover, in the second embodiment, the position adjustment mechanism 71 includes a rotation stage 78 that has gripping parts (78b, 78c) that grip the template 1 and rotates the template 1 gripped by the gripping parts in a horizontal plane to adjust the inclination of the template 1 with respect to the X direction. This makes it possible to achieve the adjustment of the inclination of the template 1 with a simpler configuration and control.

[0078] Moreover, in the second embodiment, the stand 72 includes a plate-shaped base member 72a that is detachably attached to the two support members while being spanned across the two support pipes 15, and the linear actuator 75, the linear actuator guide 76, and the linear actuator 77 are attached to the base member 72a. This allows the first position adjustment mechanism (linear actuator 75, linear actuator guide 76) and the second position adjustment mechanism (linear actuator 77) to be stably supported by the base member 72a of the stand 72. Furthermore, since the plate-shaped base member 72a is easy to handle, the position adjustment mechanism 71 and the stand 72 can be easily attached and detached.

[0079] <Modifications, etc.> The present invention is not limited to the above-described embodiment, but includes various modified examples. For example, the above-described embodiment has been described in detail to facilitate understanding of the contents of the present invention, but the present invention is not necessarily limited to having all the configurations described in the above-described embodiment.
