DETAILED DESCRIPTION OF THE EMBODIMENT

[0023] Hereinafter, based on the drawings, an embodiment of a guide rail setting device and a guide rail setting method for an elevator to which the present invention is applied will be described in detail. In the embodiment described below, first, the guide rail setting device of the elevator will be described, and then the guide rail setting method using the guide rail setting device will be described.

[0024] <<Guide Rail Setting Device of Elevator>>

[0025] Figure 1 It is a top view showing the structure of the guide rail setting device 1 of the embodiment. And,Figure 2 is a top view showing the installation environment of the guide rail setting device for explaining the embodiment, and is a view inside the hoistway 2 of the elevator before installing the Figure 1 guide rail setting device 1 shown in the figure. Further, Figure 3 and Figure 4 are enlarged views (one) and (two) showing the main part of the guide rail setting device 1 of the embodiment, and are Figure 1 an enlarged view of part [A] of. The guide rail setting device 1 described using the above drawings is a device for setting a pair of guide rails 3 on the inner peripheral wall 21 of the hoistway 2 of an elevator. The guide rail setting device 1 positions the guide rail 3 based on the piano wire 5 hanging in the hoistway 2. The work car 4 is suspended by a rope 6. And, the following guide shoes 7 are fixed to the work car 4. Here, before explaining the structure of the guide rail setting device 1, the installation environment of the guide rail setting device 1 will be explained.

[0026] [Hoistway 2]

[0027] The hoistway 2 is a space surrounded by the inner peripheral wall 21 in four directions, for example. The inner peripheral wall 21 is composed of two opposing wall portions (hereinafter referred to as the transverse walls 21s) on which the guide rails 3 are arranged, a wall portion (hereinafter referred to as the front wall 21f) perpendicular to the above transverse walls 21s and having a landing opening 2a, and a wall portion (hereinafter referred to as the rear wall 21b) opposing the front wall 21f.

[0028] [Guide rail 3]

[0029] The guide rail 3 is a steel member that guides the elevator car to be accommodated in the hoistway 2 of the elevator in the traveling direction, and is a T-shaped steel (especially refer to Figure 3 , Figure 4 ). The guide rail 3 is arranged, for example, along two opposing transverse walls 21s in the inner peripheral wall 21 with a gap from the center of gravity [G] of the above elevator car, and is positioned by the guide rail setting device 1 within an error range of several millimeters from the reference position. And, the positioned guide rail 3 is fixed to the inner peripheral wall 21 (here, the transverse wall 21s) using mounting metal parts. The positioning of the guide rail 3 and the fixing to the inner peripheral wall 21 are performed at multiple locations in the vertical direction, whereby the guide rail 3 is vertically erected.

[0030] When being positioned by the guide rail setting device 1, such a guide rail 3 is arranged in a state where the flange portion of the T-shaped steel faces the transverse wall 21s and the plate (blade) protruding from the center of the flange portion faces the center side of the hoistway 2, and is temporarily fixed to the transverse wall 21s.

[0031] [Work car 4]

[0032] When performing the installation work of the guide rail 3, the operator rides in the work car 4. Such a work car 4 is composed of, for example, a work floor 4a in a quadrilateral shape, and handrails 4b erected on the periphery of the work floor 4a and arranged to surround the quadrilateral area. Such a work car 4 is suspended between the guide rails 3 in the hoistway 2 by a rope 6 and can move freely in the hoistway 2 by the lifting drive of the rope 6. In the state of being suspended by the rope 6, the work car 4 is formed such that the handrail 4b is substantially parallel to the inner peripheral wall 21 of the hoistway 2.

[0033] [Steel piano wire 5]

[0034] The steel piano wire 5 is a steel wire used as a positioning reference for the guide rail 3. The steel piano wire 5 is suspended in the hoistway 2 from the topmost part of the building where the elevator is installed with a counterweight installed and is stretched vertically. The guide rail 3 is adjusted in position in the front-back, left-right directions with reference to the steel piano wire 5.

[0035] [Rope 6]

[0036] The rope 6 suspends the work car 4 on the rear wall 21b side with respect to the center of gravity [G] of the work car 4. As a result, the work car 4 is suspended in the hoistway 2 in a state of being inclined toward the front wall 21f side. And here, the wall portion perpendicular to the transverse wall 21s and having the landing opening 2a is set as the front wall 21f. However, the work car 4 can also be inclined toward the rear wall 21b side where the landing opening 2a is not provided. In this case, hereinafter, the wall portion where the landing opening 2a is not provided (the rear wall 21b side in the drawing) becomes the front wall.

[0037] And the rope 6 is wound around a hoist (not shown here), and the work car 4 can be lifted and lowered by winding the rope 6 by this hoist.

[0038] [Guide shoe 7]

[0039] The guide shoe 7 is fixed in a state of protruding from the work car 4 toward the transverse wall 21s. The guide shoe 7 has wall portions that sandwich the plate of the guide rail 3 with a gap from the directions of the front wall 21f and the rear wall 21b, and the wall portions are arranged to gently contact the plate of the guide rail 3. Thus, the guide shoe 7 makes the guide rail 3 move following the movement of the work car 4 in the front-back direction y (the first direction) between the front wall 21f and the rear wall 21b. In addition, for the illustration of the drawings, Figure 3 and Figure 4 the illustration of the guide shoe 7 is omitted.

[0040] [Guide rail setting device 1]

[0041] The guide rail setting device 1 is used by being fixed relative to the guide rail 3 arranged in the lifting passage 2 and the work car 4 suspended in the lifting passage 2 in such a state, and is a device for positioning and fixing the guide rail 3 relative to a pair of transverse walls 21s with reference to the piano wire 5.

[0042] Such a guide rail setting device 1 includes a pair of front wall distance adjusting members 101, a pair of transverse wall distance adjusting members 102, a disassembly and assembly mechanism 103, a position measuring member 104, a gauge 105, a control unit 106, a power supply unit 107, an operation unit 108, and a contact detection member 109. The above components are configured as follows.

[0043] 〈Front wall distance adjusting member 101〉

[0044] The front wall distance adjusting member 101 is fixed to the work car 4, and by adjusting the distance between the front wall 21f and the work car 4, the position of the guide rail 3 fixed to the work car 4 in the first direction is adjusted. The first direction is the front-rear direction y between the front wall 21f and the rear wall 21b.

[0045] The front wall distance adjusting member 101 is fixed to the work car 4 at two positions separated by the landing opening 2a provided in the front wall 21f. The above-mentioned pair of front wall distance adjusting members 101 can be directly disassembled and assembled relative to the work car 4. Such a front wall distance adjusting member 101 is provided on the front wall 21f side in a state of being fixed to the work car 4, and further extends toward the front wall side in the state of being provided on the front wall 21f side, and is provided by extending to press the front wall 21f.

[0046] Here, the work car 4 is suspended on the rear wall 21b side with respect to the center of gravity [G], and thus is in a state of tilting toward the front wall 21f side. Therefore, by extending the front wall distance adjusting member 101 fixed to the work car 4 to press the front wall, the distance [D] between the front wall 21f and the work car 4 can be adjusted. And when the work car 4 moves in the front-rear direction y as described above, the front wall distance adjusting member 101 can move the guide rail 3 in the front-rear direction y via the guide shoe 7.

[0047] At two positions separated in the left-right direction x perpendicular to the front-rear direction y to an extent that sufficient space can be ensured for the operator, such a front wall distance adjusting member 101 is fixed to the armrest 4b of the work car 4. And each front wall distance adjusting member 101 is preferably fixed to the part of the armrest 4b parallel to the transverse wall 21s in an overlapping manner. Thus, according to the fixing of the front wall distance adjusting member 101 to the work car 4, the interior of the work car 4 will not become smaller, and the operability inside the work car 4 can be ensured.

[0048] The above-described distance adjusting member 101 for the telescopic front wall is constituted by a linear actuator that uses electricity, hydraulics, or pneumatics as a driving force. In particular, a linear actuator formed by an electric ball screw that is difficult to change in length even when a pressing force is applied during stoppage is applied. This is because: after the distance adjusting member 101 for the front wall adjusts the guide rail 3 to a predetermined position, it is necessary to maintain the position of the guide rail 3 during the period until the guide rail 3 is fixed.

[0049] Moreover, the distance adjusting member 101 for the front wall may include a length detecting member (not shown) that detects a predetermined telescopic length. This length detecting member is a unit that detects the initial length of the distance adjusting member 101 for the front wall, that is, the length before the distance adjusting member 101 for the front wall is extended. Such a length detecting member uses a limit switch built into the distance adjusting member 101 for the front wall. In addition to this, a distance sensor that measures the distance between the front end of the distance adjusting member 101 for the front wall and the inner peripheral wall 21, or an encoder built into the drive unit of the distance adjusting member 101 for the front wall may also be used.

[0050] 〈Distance adjusting member 102 for the transverse wall〉

[0051] The distance adjusting member 102 for the transverse wall is fixed to the guide rail 3, and by adjusting the distance between the two transverse walls 21s and the guide rail 3, the position of the guide rail 3 in the second direction is adjusted. The second direction is the left-right direction x between the two transverse walls 21s.

[0052] The distance adjusting member 102 for the transverse wall is fixed to the guide rail 3 via the following detachable mechanism 103, for example, and the fixed state with respect to the guide rail 3 can be made flexible by the detachable mechanism 103. In addition, the distance adjusting member 102 for the transverse wall may also be a structure that is directly and flexibly fixed to the guide rail 3.

[0053] In a state of being fixed to the guide rail 3, the distance adjusting member 102 for the transverse wall is telescopic in the extending direction, and the position of the work car 4 between the two transverse walls 21s is adjusted by the telescoping. Thus, the distance adjusting member 102 for the transverse wall moves the guide rail 3 in the left-right direction x via the detachable mechanism 103.

[0054] Such a transverse wall distance adjustment member 102 is fixed to the guide rail 3 via a disassembly and assembly mechanism 103 at a position close to the guide rail 3 and deviated in the front-rear direction y with respect to the guide rail 3. Thus, even when the distance between the guide rail 3 and the transverse wall 21s is narrow, a larger telescopic range of the transverse wall distance adjustment member 102 can be obtained compared to the case where the transverse wall distance adjustment member 102 is directly fixed to the guide rail 3. That is, when the transverse wall distance adjustment member 102 is directly fixed to the guide rail 3, the transverse wall distance adjustment member 102 is disposed between the flange surface of the guide rail 3 and the transverse wall 21s, so the telescopic range of the transverse wall distance adjustment member 102 is limited by the interval between the flange surface of the guide rail 3 and the transverse wall 21s. In contrast, when the transverse wall distance adjustment member 102 is fixed to a position deviated in the front-rear direction y with respect to the guide rail 3 via the disassembly and assembly mechanism 103, the telescopic range of the transverse wall distance adjustment member 102 is not limited by the interval between the flange surface of the guide rail 3 and the transverse wall 21s. As a result, the adjustment range of the guide rail 3 in the left-right direction by each transverse wall distance adjustment member 102 can be expanded.

[0055] Such a transverse wall distance adjustment member 102 is also preferably of the same structure as the above-described front wall distance adjustment member 101. And this transverse wall distance adjustment member 102 may also be provided with the same length detection member as the above-described front wall distance adjustment member 101. In addition, Figure 1 FIG. shows a structure in which a pair of transverse wall distance adjustment members 102 are provided on both sides of the work car 4 facing the transverse wall 21s, but the transverse wall distance adjustment member 102 may also be any one. In this case, the guide rail 3 is inclined in the direction where the transverse wall distance adjustment member 102 is provided.

[0056] 〈Disassembly and assembly mechanism 103〉

[0057] The disassembly and assembly mechanism 103 is a mechanism used to fix the transverse wall distance adjustment member 102 to the guide rail 3 (especially refer to Figure 3 、 Figure 4 ). The disassembly and assembly mechanism 103 is fixed to each transverse wall distance adjustment member 102 and may also be integrally formed with each transverse wall distance adjustment member 102. The above disassembly and assembly mechanism 103 extends in a direction perpendicular to the telescopic direction of each transverse wall distance adjustment member 102 and is configured as a clamping mechanism that clamps the flange portion of the T-shaped steel constituting the guide rail 3 from the front-rear direction y.

[0058] Such a disassembly and assembly mechanism 103 has a pair of holding portions 103a that clamp and hold the flange portion of the guide rail 3 from both end sides, and a clamping handle 103b for adjusting the interval between the pair of holding portions 103a. The disassembly and assembly mechanism 103 adjusts the interval between the holding portions 103a by rotating the clamping handle 103b, so that the holding and releasing of the guide rail 3 by clamping become easy.

[0059] Each of the pair of holding portions 103a has a C-shaped configuration that clamps the end edges on both sides of the flange portion of the guide rail 3 from two directions, preventing the distance adjusting member 102 for the transverse wall from coming off the guide rail 3. Here, Figure 3 The state in which the distance adjusting member 102 for the transverse wall extends is shown, Figure 4 The state in which the distance adjusting member 102 for the transverse wall is shortened is shown. As described above Figure 3 、 Figure 4 As shown, when the distance adjusting member 102 for the transverse wall expands and contracts, a moment is generated with respect to the disassembly and assembly mechanism 103 about the portion [B] closer to the distance adjusting member 102 for the transverse wall among the end edges on both sides of the flange portion of the guide rail 3. At this time, the holding portion 103a having a shape that sandwiches the end edges on both sides of the flange portion from two directions prevents it from coming off the guide rail 3 even when the above-mentioned moment is generated.

[0060] 〈Position measuring member 104〉

[0061] The position measuring member 104 is a unit that measures the position of the guide rail 3 in the front-rear direction y and the left-right direction x with respect to a pair of piano wires 5 that serve as a reference for centering the guide rail 3. The position measuring member 104 is directly fixed to the plate of the guide rail 3 or fixed in a predetermined state via a bracket. The method of position measurement of such a position measuring member 104 is not limited, but it is preferable to use a small and lightweight member, for example, an optical piano wire position detector, which has a hole portion 104a through which the piano wire 5 passes and measures the position of the piano wire 5 passing through the hole portion 104a.

[0062] 〈Gauge 105〉

[0063] The gauge 105 is a member for holding two guide rails 3 at a predetermined interval and is detachable from the guide rail 3. The gauge 105 includes a fixing portion 105a that holds both ends of the guide rail 3 in a predetermined state (see Figure 3 、 Figure 4 ). The fixing portion 105a has a reference surface that presses against two surfaces facing different directions at both ends of the guide rail 3, for example, and a clamping member that presses the guide rail 3 against the reference surface, and is horizontally fixed between a pair of guide rails 3 to hold the guide rails 3 fixed at both ends of the gauge 105 at a predetermined distance.

[0064] 〈Control unit 106〉

[0065] The control unit 106 is a unit for controlling the distance adjustment performed by the front wall distance adjustment member 101 and the transverse wall distance adjustment member 102. Such a control unit 106 is constituted by a computer such as an embedded microcomputer, for example. The control unit 106 receives the position information of the track acquired by the position measurement member 104, and adjusts the position of the guide rail 3 by automatically controlling the expansion and contraction of the front wall distance adjustment member 101 and the transverse wall distance adjustment member 102. The control unit 106 automates the position adjustment operation of the guide rail 3, and at the same time performs the position adjustment operations in two directions, namely the left-right direction x and the front-back direction y of the guide rail 3, thereby supporting the positioning operation of the guide rail 3. In addition, in the guide rail setting method described below, the sequence of the position adjustment of the guide rail 3 performed by the control unit 106 is described.

[0066] 〈Power supply unit 107〉

[0067] The power supply unit 107 is a unit that supplies the power required to drive each part of the guide rail setting device 1. Such a power supply unit 107 can use, for example, a switching power supply that converts a general commercial power supply into a voltage used by the guide rail setting device 1 or a rechargeable battery.

[0068] 〈Operation unit 108〉

[0069] The operation unit 108 is a unit for an operator to operate the guide rail setting device 1. The operation unit 108 includes buttons as an input unit. And, it includes an output unit for the operator to confirm the states of the front wall distance adjustment member 101, the transverse wall distance adjustment member 102, and the position measurement member 104. The output unit is a display lamp or the like that lights up at the time of display output and completion of the operation. Furthermore, the operation unit 108 includes a communication unit for communicating with the control unit 106. This communication is performed by wired or wireless means.

[0070] 〈Contact detection member 109〉

[0071] The contact detection member 109 is a unit for detecting the contact of the front ends of the front wall distance adjustment member 101 and the transverse wall distance adjustment member 102 with the inner peripheral wall 21. The contact detection member 109 preferably uses a current sensor that measures the current flowing into the front wall distance adjustment member 101 and the transverse wall distance adjustment member 102.

[0072] In addition, as the contact detection component 109, a contact sensor or a distance sensor provided at the front ends of the front wall distance adjustment component 101 and the side wall distance adjustment component 102 can also be used. However, the contact sensor or the distance sensor needs to be additionally provided at the front ends of the front wall distance adjustment component 101 and the side wall distance adjustment component 102. Therefore, signal lines for transmitting the signals of the sensors to the control unit 106 are required. In contrast, if a current sensor is used, it can be installed near the control unit 106 and the power supply unit 107, and there is an advantage that the operator does not need to handle the signal lines.

[0073] "Guide Rail Setting Method"

[0074] Figure 5 and Figure 6 are flowcharts (Part 1) and (Part 2) showing the guide rail setting method using the guide rail setting device of the embodiment. Hereinafter, based on the above Figure 5 and Figure 6 and with reference to the above Figures 1 to 4 and other required drawings, the guide rail setting method will be described.

[0075] 〈Step S00〉

[0076] In step S00, the operator gets into the work car 4 and fixes the front wall distance adjustment component 101 to the handrail 4b of the work car 4. At this time, the front wall distance adjustment component 101 is shortened to the initial length so as not to interfere with the fixing operation.

[0077] 〈Step S01〉

[0078] In step S01, the operator operates a hoist (not shown here) to raise and lower the work car 4 and move it to a predetermined height.

[0079] 〈Step S02〉

[0080] In step S02, the operator fixes a pair of side wall distance adjustment components 102 to the guide rail 3 via the disassembly and assembly mechanism 103. At this time, the side wall distance adjustment component 102 is shortened to the initial length so as not to interfere with the fixing operation. And the operator fixes the position measurement component 104 to a pair of guide rails 3 in a predetermined state respectively.

[0081] And the operator fixes the gauge 105 to the two guide rails 3 in a predetermined state. In this state, as Figure 1 shown, the center of gravity [G] of the work car 4 is located at a point that is at a distance [L] away from the gauge 105 toward the front wall 21f side, and the work car 4 tilts toward the front wall 21f side.

[0082] 〈Step S03〉

[0083] In step S03, the operator inputs, through the operation of the operation unit 108, an instruction to bring the front ends of the distance adjustment member 101 for the front wall and the distance adjustment member 102 for the transverse wall into contact with the inner peripheral wall 21.

[0084] Thereby, the control unit 106 extends the distance adjustment member 101 for the front wall and the distance adjustment member 102 for the transverse wall. When the control unit 106 detects, based on the signals from the contact detection member 109, that the front ends of the distance adjustment member 101 for the front wall and the distance adjustment member 102 for the transverse wall are respectively in contact with the inner peripheral wall 21, the control unit 106 stops the extension of the distance adjustment member 101 for the front wall and the distance adjustment member 102 for the transverse wall. In this way, by automating the contact between the front ends of the distance adjustment member 101 for the front wall and the distance adjustment member 102 for the transverse wall and the inner peripheral wall 21, the workload of the operator can be reduced.

[0085] In addition, the control unit 106 outputs a notification that the front ends of the distance adjustment member 101 for the front wall and the distance adjustment member 102 for the transverse wall are in contact with the inner peripheral wall 21 to the output unit of the operation unit 108. Thereby, the operator can confirm that the contact between the front ends of the distance adjustment member 101 for the front wall and the distance adjustment member 102 for the transverse wall and the inner peripheral wall 21 has been completed.

[0086] 〈Step S04〉

[0087] In step S04, after the operator confirms in the output unit of the operation unit 108 that the contact between the front ends of the distance adjustment member 101 for the front wall and the distance adjustment member 102 for the transverse wall and the inner peripheral wall 21 has been completed, the operator inputs, through the operation of the operation unit 108, an instruction to perform the positioning of the guide rail 3.

[0088] Thereby, based on the information from the position measurement member 104, the control unit 106 controls the expansion and contraction of the distance adjustment member 101 for the front wall and the distance adjustment member 102 for the transverse wall respectively, and moves the work car 4, so as to position the guide rail 3 fixed to the work car 4 at a predetermined position. In this way, by automating the positioning operation of the guide rail 3, the workload of the operator can be reduced.

[0089] In addition, the control unit 106 outputs a notification that the guide rail 3 has been positioned to the output unit of the operation unit 108. At this time, for example, if the positioning is completed, the operation unit 108 lights up a display lamp provided as the output unit, and if the positioning is not completed, the operation unit 108 turns off the lamp. Through the lighting of this lamp, the operator can confirm that the guide rail 3 has been positioned.

[0090] 〈Step S05〉

[0091] In step S05, the operator fixes the guide rail 3 to the inner peripheral wall 21 using a bracket. At this time, during the period until the guide rail 3 is fixed, the front wall distance adjustment member 101 and the transverse wall distance adjustment member 102 hold the position of the guide rail 3 by pushing the front end against the inner peripheral wall 21.

[0092] In addition, based on the information from the position measurement member 104, the control unit 106 always outputs the positioning state of the guide rail 3 to the output unit of the operation unit 108. Thus, during the fixing operation of the guide rail 3 performed by the operator, when the position of the guide rail 3 deviates, the operation unit 108 turns off the display lamp provided as the output unit of the operation unit 108, enabling the operator to recognize the deviation of the position of the guide rail 3.

[0093] 〈Step S06〉

[0094] In step S06, the operator determines whether the guide rail 3 is in the positioned state by the lighting of the display lamp in the operation unit 108. If it is lit, it is determined that the position of the guide rail 3 is good (yes) and the process proceeds to step S07. On the other hand, when the display lamp is off, the operator determines that the position of the guide rail 3 is not good (no) and returns to step S04. Then, again through the operation of the operation unit 108, an instruction to perform the positioning of the guide rail 3 is input.

[0095] 〈Step S07〉

[0096] In step S07, the operator determines whether the fixing of the guide rail 3 is completed in the positioned state. If it is determined that the fixing is completed (yes), the process proceeds to the next step S08. On the other hand, if the fixing is not completed (no), the process returns to step S05 and the fixing operation continues.

[0097] 〈Step S08〉

[0098] In step S08, the operator inputs an instruction to shorten the front wall distance adjustment member 101 and the transverse wall distance adjustment member 102 to the initial length through the operation of the operation unit 108.

[0099] Thereby, the control unit 106 shortens the front wall distance adjustment member 101 and the transverse wall distance adjustment member 102 respectively, releasing the contact between the front ends of the front wall distance adjustment member 101 and the transverse wall distance adjustment member 102 and the inner peripheral wall 21. At this time, if the front wall distance adjustment member 101 and the transverse wall distance adjustment member 102 are equipped with length detection members, the control unit 106 returns the front wall distance adjustment member 101 and the transverse wall distance adjustment member 102 to the initial length based on the signal from the length detection member.

[0100] Further, when the control unit 106 returns the front wall distance adjustment member 101 and the side wall distance adjustment member 102 to their initial lengths, it is displayed on the output unit of the operation unit 108. Thus, based on the output of the output unit of the operation unit 108, the operator can confirm that the front wall distance adjustment member 101 and the side wall distance adjustment member 102 have returned to their initial lengths. Therefore, it is possible to save the labor and time for the operator to successively confirm the lengths of the front wall distance adjustment member 101 and the side wall distance adjustment member 102 in the front wall distance adjustment member 101 and the side wall distance adjustment member 102. Also, other operations can be performed during this period, and the operation load can be reduced.

[0101] 〈Step S09〉

[0102] In step S09, the operator removes the gauge 105 from the two guide rails 3. And the operator removes the position measuring member 104 from the guide rail 3. Further, the operator releases the clamping of each guide rail 3 by the disassembly and assembly mechanism 103, and removes the disassembly and assembly mechanism 103 and the side wall distance adjustment member 102 from the guide rail 3.

[0103] 〈Step S10〉

[0104] In step S10, the operator determines whether the fixing of the guide rail 3 has been completed. When the operator has fixed both of the pair of guide rails 3 at all the predetermined height positions, it is determined that the fixing has been completed (Yes), and the process proceeds to step S11. In other cases, it is determined that the fixing has not been completed (No), and the process returns to step S01, and the subsequent steps are repeated.

[0105] 〈Step S11〉

[0106] In step S11, the operator removes the front wall distance adjustment member 101 from the work car 4, and ends the setting operation of the guide rail 3.

[0107] 《Effects of the Embodiment》

[0108] The guide rail setting device 1 of the embodiment described above is configured such that the front wall distance adjustment member 101 that adjusts the position of the guide rail 3 in the front-rear direction y and the side wall distance adjustment member 102 that adjusts the position of the guide rail 3 in the left-right direction x are divided into different members and separately fixed to the work car 4 and the guide rail 3. Thus, the guide rail setting device 1 is divided into a plurality of small and lightweight members, and the operation becomes easy. Therefore, the fixing and removal of the guide rail setting device 1 with respect to the work car 4 and the guide rail 3 are performed by fixing each of the divided small and lightweight members. Therefore, compared with the case where the guide rail setting device 1 is configured as a single unit, the operation load of fixing and removing the guide rail setting device 1 can be reduced.

[0109] Moreover, Figure 7 FIG. Figure 7 is a top view showing a method of setting the guide rail according to the embodiment. In step S09, the state after removing the gauge 105, the disassembly and assembly mechanism 103, and the distance adjustment member 102 for the transverse wall from the guide rail 3 is shown. As shown in this figure, when changing the height of the work car 4 in the setting order of the guide rail 3, it is possible to remove only the components fixed to the guide rail 3 while the distance adjustment member 101 for the front wall remains fixed to the work car 4. Thus, the work load can also be reduced.

[0110] Moreover, in this state, since the space inside the work car 4 can be ensured, other operations performed at each height in the hoistway 2 can also be performed without stress. Therefore, it is also possible to perform the setting of the guide rail 3 and other operations in parallel at each height in the hoistway 2. As a result, the work efficiency of the overall setting of the elevator device can be improved.

[0111] In addition, the present invention is not limited to the above-described embodiments and modified examples, and also includes various modified examples. For example, the above-described embodiments are embodiments described in detail for easy understanding of the present invention, and are not limited to having all the structures described. Moreover, a part of the structure of a certain embodiment can be replaced with the structure of another embodiment, and the structure of another embodiment can also be added to the structure of a certain embodiment. Also, it is possible to add, delete, or replace other structures to a part of the structure of each embodiment.
