Description

Device and method for mounting sill

Technical Field

The invention relates to a device for mounting a sill and a method for mounting the sill.

Background

In developed countries including japan, north america, and europe, the reduction of workers associated with the aging of young children is a problem. This problem is no exception in the elevator installation industry. Therefore, even if the number of workers is reduced, the efficiency and labor saving of the construction work are required to be improved so as to cope with the number of constructions up to now.

In the installation work of an elevator, there are various works such as in-tower measurement, guide rail installation, doorway installation, in-tower equipment installation, car assembly, and the like. In these mounting operations, the doorway mounting is an operation of closing the opening of the hoistway. Therefore, considering the safety aspect of the construction work, it is preferable to quickly end the doorway mounting. However, the doorway mounting is a work repeated for each floor of the building, and a work for handling long members or heavy objects, and therefore, requires labor and time.

The entrance and exit of the elevator mainly comprise a sill, a three-side frame and a door pocket. The sill is a component that serves as the basis for the doorway. In the work of attaching the sill, it is required to adjust the position of the sill in each direction of 6 degrees of freedom with high accuracy, such as to make a gap between the elevator car which ascends and descends on the ascending and descending path and the sill of each floor constant, or to horizontally attach the sill so as to smoothly move the opening and closing door. The 6 degrees of freedom are degrees of freedom in 6 directions including an X-axis direction, a Y-axis direction, a Z-axis direction, a Pitch (Pitch) direction, a Roll (Roll) direction, and a Yaw (Yaw) direction.

In the case of adjusting the position of the sill with high accuracy in the mounting work of the sill, it is considered to use a device or jig for supporting the high efficiency of the adjustment work and the reduction of labor. Patent document 1 describes a technology related to an elevator hall sill adjusting jig and a sill adjusting method. The technique described in patent document 1 has an object to provide an elevator hall sill adjustment jig and a sill adjustment method that can adjust the longitudinal direction and the elevation angle of the sill of the elevator hall. To solve this problem, patent document 1 describes a structure of an elevator hall sill adjusting jig including an adjusting jig fixed to a side surface of a sill, having notches formed in upper and lower adjusting plates, respectively, and adjusting an elevation angle of the sill in a horizontal direction and an elevator hall plane by using a positional relationship between a center line hanging from a top of an elevator hoistway and the notches of the upper and lower adjusting plates, respectively.

Disclosure of Invention

Problems to be solved by the invention

In a conventional work for adjusting the position of a sill, the sill is temporarily fixed to a bracket fixed to a wall surface in an elevation path in advance, and an operator strikes the bracket or the sill with a hammer based on a centering wire or a level vertically lowered from the ceiling of the elevation path, thereby adjusting the posture and the position of the sill. However, in this method, the moving direction, angle, and moving amount of the sill change due to temporary fixing of the sill, increase and decrease of the striking position, striking angle, and striking force of the hammer, and the like. Therefore, it is difficult to adjust the position of the sill as intended by the operator, and skilled skills and experience are required. Further, the following problems are encountered for immature workers: the sill is struck with the hammer several times before the position adjustment of the sill is finished, resulting in a long time required for the work.

In relation to such a problem, the elevator hall sill adjusting jig described in patent document 1 is merely an index plate for easily visually confirming a positional relationship between a steel wire as a centering line suspended from the top of the hoistway and notches of the upper and lower adjusting plates of the sill adjusting jig. Therefore, even when the elevator hall sill adjusting jig described in patent document 1 is used, the worker needs to strike the sill with a hammer while visually confirming the positional relationship between the center line and the notch. Therefore, a skilled skill is required for the position adjustment of the sill.

The invention aims to provide a technology for adjusting the position of a sill more easily than the prior art.

Means for solving the problems

In order to solve the above problem, for example, the structure described in the claims is adopted. The present application includes a plurality of means for solving the above-described problem, and one of them is a device for mounting a sill, including: a holding unit that holds a sill that is a doorway member of a building with an elevator; and a positioning mechanism for positioning the sill by moving the holding part.

Detailed Description

< first embodiment >

Fig. 1 is a perspective view showing a structure of a sill mounting device of the first embodiment, and fig. 2 is a side view of the structure of the sill mounting device of the first embodiment as viewed from a direction a of fig. 1. In fig. 1 and 2, the X-axis direction represents the entrance/exit direction of the elevator, the Y-axis direction represents the width direction of the entrance/exit of the elevator, and the Z-axis direction represents the height direction of the elevator. The Roll (Roll) direction indicates a rotation direction around the X axis, the Pitch (Pitch) direction indicates a rotation direction around the Y axis, and the Yaw (Yaw) direction indicates a rotation direction around the Z axis. The X-axis direction and the Y-axis direction correspond to two axial directions parallel to a horizontal plane, i.e., horizontal biaxial directions, and the Z-axis direction corresponds to a direction orthogonal to the horizontal plane, i.e., a vertical direction. The direction of entrance and exit of the elevator corresponds to the depth direction when the hoistway is viewed from the elevator landing, i.e., the direction in which people enter and exit, and the width direction of the entrance and exit of the elevator corresponds to the direction in which the doors of the elevator open and close.

The sill installation apparatus 10 is used when installing a sill 11 at a doorway part of an elevator. As shown in fig. 1 and 2, the sill-mounting device 10 mainly includes: a holding portion 12 that holds the sill 11; and a positioning mechanism 14 that positions the sill 11 held by the holding portion 12. The sill mounting apparatus 10 further includes: a posture measuring unit 16 that measures the posture of the sill 11 held by the holding unit 12; a relative position confirmation unit 18 that confirms a relative position between a measurement reference (described later) in the hoistway of the elevator and the sill 11 held by the holding unit 12; a height detection unit 20 that detects that the sill 11 held by the holding unit 12 is disposed at a predetermined height from the floor 19 of the building; and a base 22 that supports the holding portion 12 and the positioning mechanism 14.

The positioning mechanism 14 is disposed on the lower surface side of the arm 24. The arm 24 has high rigidity and is assembled to the frame shape. A cover 23 is fixed to the upper surface of the arm 24. The cover 23 is formed of a flat plate-like member. A device posture measuring unit 25 is attached to the upper surface of the cover 23. The device posture measuring unit 25 measures the posture of the sill mounting device 10 with respect to a horizontal plane parallel to the X-axis direction and the Y-axis direction. The posture of the sill mounting device 10 with respect to the horizontal plane means the inclination of the sill mounting device 10 with respect to the horizontal plane. The state in which the posture of the sill-mounting device 10 is parallel to the horizontal plane is a state in which the inclination of the sill-mounting device 10 is zero.

(holding part 12)

The holding portion 12 is a portion that sandwiches and holds the sill 11 in the vertical direction. The holding portions 12 are arranged in 2 in the Y-axis direction at a distance. The respective holding portions 12 have the following common configuration. As shown in fig. 2, the holding portion 12 includes a first clamp member 26, a second clamp member 27, a fastener 28, and a knob 29. The first clamping member 26 has a housing space 30 in which the sill 11 can be housed. The first clamping member 26 is formed in a substantially inverted U-shape as viewed from the direction a of fig. 1. The second clamping member 27 is rotatably attached to the first clamping member 26 about a fulcrum portion 31. The housing space 30 of the first clamp member 26 is closed when the second clamp member 27 is rotated in one direction (clockwise direction in fig. 2) about the fulcrum portion 31, and is opened when rotated in the other direction (counterclockwise direction in fig. 2).

In the following description, the posture of the second clamping member 27 in the state where the housing space 30 of the first clamping member 26 is closed by the second clamping member 27 is referred to as a closed state, and the posture of the second clamping member 27 in the state where the housing space 30 of the first clamping member 26 is opened by the second clamping member 27 is referred to as an open state. The posture of the second clamping member 27 shown in fig. 2 is a closed state.

The fastener 28 is a fitting for holding the second clamping member 27 in the closed state or releasing the closed state thereof. When the second clamp member 27 is in the closed state, the height dimension (dimension in the Z-axis direction) of the housing space 30 of the first clamp member 26 is slightly larger than the height dimension of the sill 11. The height dimension of the sill 11 is determined as a dimension by specification. In contrast, the width dimension (dimension in the X-axis direction) of the sill 11 is not necessarily a fixed dimension, and may be changed within a predetermined range. In the present embodiment, the width dimension (dimension in the X-axis direction) of the housing space 30 in the holding portion 12 is set to be equal to or greater than the maximum width dimension of the sill 11 handled by the sill mounting apparatus 10. This allows the same holding portion 12 to hold the sills 11 having different width dimensions.

The knob 29 is mounted to the second clamping member 27 by engagement of the screws with each other. The knob 29 receives the sill 11 in the receiving space 30 of the first clamping member 26 to bring the second clamping member 27 into the closed state, and in this state, the knob 29 is rotated in the first direction to generate a force pressing the sill 11 against the first clamping member 26. The sill 11 is held in a fixed state by the holding portion 12 by the pressing force generated by the knob 29. Further, by holding the sill 11 by the pair of 2 holding portions 12 on the left and right, the pair of holding portions 12 and the sill 11 can be moved integrally.

When the pressing force is released, the knob 29 may be rotated in a second direction opposite to the first direction. When the sill 11 is held by the pair of holding portions 12, marks such as lines and dots to be marks may be added to predetermined portions of the sill 11 (for example, the upper surface of the sill 11) in advance, and the sill 11 may be held with the positions of the marks as references. This enables the holding portion 12 to hold the sill 11 such that the relative positional relationship between the holding portion 12 and the sill 11 is always constant. In addition, the holding portion 12 may hold the sill 11 in any manner as long as it can hold the sill 11 horizontally. For example, when the sill 11 is a magnetic body, the holding portion 12 may hold the sill 11 by a magnetic force.

(positioning mechanism 14)

The positioning mechanism 14 is a mechanism that positions the sill 11 by moving the sill 11 held by the holding portion 12 integrally with the holding portion 12. As described above, the positioning mechanism 14 includes a plurality of adjustment portions that adjust the position of the sill 11 held by the holding portion 12. The plurality of adjustment portions adjust the positions of the sills 11 in different directions. In the present embodiment, as an example, the positioning mechanism 14 is configured to include a first adjusting unit 35 and a second adjusting unit 36.

The first adjusting portion 35 can adjust the position of the sill 11 held by the holding portion 12 in the X-axis direction, the Y-axis direction, and the Z-axis direction. Specifically, the first adjustment unit 35 includes: an X-axis table capable of adjusting the position of the sill 11 in the X-axis direction; a Y-axis table capable of adjusting the position of the sill 11 in the Y-axis direction; and a Z-axis table capable of adjusting the position of the sill 11 in the Z-axis direction. The first adjustment unit 35 includes 3 rotation knobs for individually (independently) adjusting the position of the sill 11 in each of the X-axis direction, the Y-axis direction, and the Z-axis direction.

The second adjustment unit 36 can adjust the position of the sill 11 held by the holding unit 12 in the roll direction, pitch direction, and yaw direction. Specifically, the second adjustment unit 36 includes: a rolling table capable of adjusting the position of the sill 11 in the rolling direction; a pitching table capable of adjusting the position of the sill 11 in a pitching direction; and a deflecting table capable of adjusting the position of the sill 11 in a deflecting direction. The second adjustment unit 36 includes 3 rotation knobs for adjusting the position of the sill 11 in each of the roll direction, pitch direction, and yaw direction. As described above, the roll direction indicates a direction of rotation about the X axis, the pitch direction indicates a direction of rotation about the Y axis, and the yaw direction indicates a direction of rotation about the Z axis. When the position of the sill 11 is adjusted in any one of the roll direction, pitch direction, and yaw direction, the posture of the sill 11 changes. Therefore, the second adjustment part 36 can be said to be a part that adjusts the posture of the sill 11.

The first adjustment portion 35 is mounted on the base 22 via a pedestal 37 (see fig. 2). The pedestal 37 is a metal member. The pedestal 37 is fixed to the upper surface of the base 22. As a means for fixing the members to each other including the pedestal 37 and the base 22, screw fixation may be considered, but a fixing means other than screw fixation may be adopted. The first adjusting portion 35 is fixed to the upper surface of the base 37. Among the 3 tables provided in the first adjustment unit 35, the table disposed at the uppermost portion is fixed to the lower surface of the arm 24.

The second adjusting portion 36 is disposed on the opposite side of the first adjusting portion 35 in the longitudinal direction (X-axis direction) of the arm 24. The second adjustment portion 36 is supported by the arm 24 using an upper side plate 38, a lower side plate 39, and a plurality of connection studs 40. The upper side plate 38 is formed in a rectangular shape in plan view. An upper side plate 38 is secured to the lower surface of the arm 24. The lower plate 39 is formed in a rectangular shape in plan view, similarly to the upper plate 38. The plurality of connecting studs 40 connect the upper plate 38 and the lower plate 39. The connecting studs 40 are disposed at 1 in each of the four corners of the upper plate 38 and the lower plate 39. The second adjusting portion 36 is disposed between the upper plate 38 and the lower plate 39. The second adjustment portion 36 is fixed to the upper surface of the lower plate 39. The second adjusting unit 36 is disposed closer to the holding unit 12 than the first adjusting unit 35 in a horizontal plane parallel to the X-axis direction and the Y-axis direction. Specifically, the second adjustment portion 36 is disposed directly above the sill 11 held by the holding portion 12, and the first adjustment portion 35 is disposed at a position shifted in the X-axis direction from the position directly above the sill 11.

The support plate 41 is fixed to the table disposed at the uppermost portion of the 3 tables included in the second adjusting portion 36. The support plate 41 is a long plate that is long in the Y axis direction. The support plate 41 is provided with a plurality of through holes 42 (see fig. 1) corresponding to the plurality of connecting studs 40. The diameter of the through hole 42 is set larger than the diameter of the connecting stud 40, and the positional interference between the connecting stud 40 and the support plate 41 is avoided by the difference in the diameters.

A coupling plate 43 is fixed to the lower surface of the support plate 41. The coupling plate 43 is a plate that couples the support plate 41 and the holding portion 12. The coupling plate 43 and the holding portion 12 are provided in a 1-to-1 relationship. The lower surface of the connecting plate 43 is fixed to the upper surface of the first clamping member 26 provided in the holding portion 12. The coupling plate 43 is disposed at the center of the upper surface of the first clamping member 26, and stands vertically from the upper surface of the first clamping member 26. When the sill-mounting device 10 is viewed in the X-axis direction, the second adjustment portion 36 and a plurality of (4 in the present embodiment) connecting studs 40 arranged around the second adjustment portion are arranged between the pair of left and right connecting plates 43.

A reinforcing member 44 is fixed to the upper surface of the support plate 41. The reinforcing member 44 is a member for reinforcing the support plate 41 to suppress flexure and the like of the support plate 41. The reinforcing member 44 is an elongated member that is long in the Y-axis direction, and is made of, for example, aluminum or an aluminum alloy. The reinforcing members 44 are disposed at both ends of the support plate 41 in the short-side direction (X-axis direction). The reinforcing member 44 is disposed parallel to the longitudinal direction (Y-axis direction) of the support plate 41. The reinforcing member 44 is not necessarily provided in the case where the support plate 41 has a sufficiently high rigidity. That is, the reinforcing member 44 may be provided as needed.

In the positioning mechanism 14 configured as described above, when any one of the 3 tables included in the first adjustment unit 35 is moved, the arm 24 moves in the same direction as the table, and the second adjustment unit 36 and the holding unit 12 move integrally with the arm 24. This enables the sill 11 held by the holding section 12 to be linearly moved in each of the X-axis direction, the Y-axis direction, and the Z-axis direction, which is the moving direction of the table in the first adjusting section 35. Therefore, the position of the sill 11 can be independently adjusted in each of the X-axis direction, the Y-axis direction, and the Z-axis direction. When any one of the 3 tables provided in the second adjustment unit 36 is moved, the support plate 41 is moved in the same direction as the table, and the holding unit 12 is moved integrally with the support plate 41. This enables the sill 11 held by the holding section 12 to be rotationally moved in each of the moving directions of the table in the second adjusting section 36, that is, the roll direction, pitch direction, and yaw direction. Therefore, the position of the sill 11 can be independently adjusted in each of the roll direction, pitch direction, and yaw direction.

It is preferable that the first adjustment unit 35 and the second adjustment unit 36 include a lock mechanism that prevents the table from moving in each direction so that the position of the sill 11 does not shift after the position of the sill 11 is adjusted by the first adjustment unit 35 and the second adjustment unit 36.

(attitude measuring section 16)

The posture measuring section 16 is fixed to the upper surface of the support plate 41 using the mounting tool 45. The posture measuring unit 16 is disposed at one end in the longitudinal direction of the support plate 41. The attitude measuring section 16 measures the attitude of the sill 11 with respect to a horizontal plane parallel to the X-axis direction and the Y-axis direction. The posture of the sill 11 with respect to the horizontal plane refers to the inclination of the sill 11 with respect to the horizontal plane. The state in which the posture of the sill 11 is parallel to the horizontal plane is a state in which the inclination of the sill 11 is zero. In the configuration of the sill mounting device 10, the positions of the respective parts of the sill mounting device 10 are adjusted in advance so that the posture of the sill 11 held by the holding part 12 and the posture of the support plate 41 are the same posture.

(relative position confirming unit 18)

The relative position confirmation unit 18 is constituted by a pair of indicator members 46. The pair of index members 46 are disposed at a predetermined interval in the Y axis direction. One of the pair of indicator members 46 is fixed to the support plate 41 by screw fixation, and the other indicator member 46 is fixed to the support plate 41 via a plate 48. As shown in fig. 3, each indicator 46 is formed of a plate having a cutout 47 in an L-shape in plan view. In the pair of indicator members 46, the curved corner portions 49 of the cutout portions 47 are arranged on an imaginary straight line 50 parallel to the longitudinal direction of the support plate 41. As shown in fig. 4 and 5, the interval Lm between the 2 curved corner portions 49 located on the virtual straight line 50 is set to be equal to the interval Lp (see fig. 5) between the 2 wires 52 suspended vertically from the ceiling of the hoistway 51 of the elevator. The 2 piano steel wires 52 are reference lines for centering of the sill 11, and are also called centering lines. The 2 steel wires 52 correspond to a measurement reference in the hoistway 51 of the elevator.

Incidentally, fig. 4 is a perspective view of a state where the sill installation device is installed in the opening of the elevator as viewed from the hoistway side, and fig. 5 is a view of a state where the sill installation device is installed in the opening of the elevator as viewed from the hall side of the building.

The relative position confirmation unit 18 is not limited to the pair of indicator members 46, and may be configured using a sensor that detects the position of the wire 52. The position of the wire 52 can be detected by a transmission type optical sensor, for example.

(height detecting section 20)

The height detection part 20 is fixed to the support plate 41 using an L-shaped plate 55. The height detection unit 20 is vertically arranged in an upright manner so as to be oriented perpendicular to the main surfaces (upper surface and lower surface) of the support plate 41. The height detection unit 20 includes a sensing unit not shown. The sensing portion is a portion that senses the horizontal laser light emitted from the laser striping machine 60. The laser striper 60 has a striper body 61 and a tripod 62 that supports the striper body 61. The reticle main body 61 emits a horizontal laser beam, which is a laser beam parallel to a horizontal plane. The height of the horizontal laser beam of the reticle main body 61 can be adjusted by changing the length of the tripod 62.

(base 22)

The base 22 is formed of a flat plate-like member. A plurality of legs 56 (see fig. 2) are attached to the lower surface of the base 22. The base 22 is disposed on the ground 19 by a plurality of feet 56. The number of the feet 56 is at least 3 so that the load applied to the base 22 can be stably supported. In the present embodiment, the base 22 is formed in a rectangular shape in a plan view, and 3 legs 56 are attached to the base 22. The plurality of leg portions 56 can be adjusted in length. The height from the floor 19 to the base 22 can be changed by uniformly adjusting the lengths of the plurality of legs 56. The inclination of the base 22 with respect to the horizontal plane can be changed by individually adjusting the lengths of the plurality of legs 56.

A counterweight 57 is mounted on the upper surface of the base 22. The counterweight 57 is detachable from the base 22. The counterweight 57 is a counterweight that applies a load to the base 22 so that the entire sill-mounting device 10 does not tilt forward due to a load applied to the base 22 via the first adjusting portion 35 and the base 37. That is, the weight 57 corresponds to the forward tilting prevention portion. The counterweight 57 is disposed on a side farther from the holding portion 12 than the first adjusting portion 35 and the base 37 in the X-axis direction. The counterweight 57 is also unnecessary due to the balance of the load applied to the base 22. That is, the weight 57 may be provided as needed.

Further, a misalignment suppressing unit 58 is connected to the base 22. The misalignment suppressing unit 58 suppresses misalignment of the base 22 provided on the floor 19 of the building via the plurality of legs 56. The misalignment suppressing unit 58 is formed of an elongated bar member that is long in the Y-axis direction. An extensible rod portion 59a is provided at one end side in the longitudinal direction of the positional deviation restraining portion 58. The telescopic rod portion 59a is a portion that changes the length of the entire displacement inhibitor 58 by extending and contracting in the longitudinal direction of the displacement inhibitor 58. Further, pad portions 59b are provided at both longitudinal end portions of the displacement suppressing portion 58. The cushion portion 59b is pressed against the side surface of the opening with a predetermined pressure when the sill-mounting device 10 is installed on the floor 19 of the building.

(sill installation method)

Next, a sill installation method using the device for installing a sill according to the first embodiment will be described with reference to a flowchart of fig. 6.

First, as shown in fig. 5, the operator draws a trimming line 66 of a predetermined size downward from the ink dot dashed line 65 that is previously inked (step S1). The dotted ink line 65 is a line horizontally drawn from the wall surface 68 near the opening 67 of the elevator, and is drawn from a surface that actually becomes the floor of the elevator by about 1m. In this case, the operator horizontally draws the trimming line 66 1m downward from the dotted ink line 65.

Next, as shown in fig. 5, the operator draws a target laser line 69 on the wall surface 68 near the opening 67 of the elevator (step S2). When the height dimension from the upper surface of the sill 11 held by the holding part 12 to the sensing part of the height detecting part 20 in the sill mounting device 10 is Hmm, the target laser line 69 is pulled to a position Hmm above the trimming line 66.

Next, the operator sets the laser marker 60 on the floor 19 of the building, and performs height alignment of the horizontal laser beam 70 (see fig. 5) emitted from the laser marker 60 (step S3). The height alignment of the horizontal laser beam 70 is performed by changing the length of the tripod 62 of the laser striper 60 so that the horizontal laser beam 70 is emitted from the laser striper 60 provided on the floor 19 toward the wall surface 68 and the height of the horizontal laser beam 70 matches the height of the target laser beam line 69.

Next, the worker sets the sill-mounting device 10 near the opening 67 of the elevator (step S4).

Next, the operator coarsely adjusts the height and posture of the doorsill-mounting device 10 (step S5). The coarse adjustment is performed by changing the length of the plurality of leg portions 56 attached to the base 22.

Next, the worker fixes the position deviation suppressing part 58 to the opening 67 of the elevator (step S6). In the case of the fixed position deviation restraining portion 58, the pair of left and right pad portions 59b are pressed against the side surfaces of the opening 67 by the stretchability of the stretchable rod portion 59a. Thus, the misalignment suppressing member 58 is fixed so that the misalignment suppressing member 58 abuts between the left and right side surfaces of the opening 67. By the fixed position deviation suppressing portion 58, the positional deviation of the base 22 can be suppressed, and the positional deviation of the entire sill mounting apparatus 10 can be suppressed.

Next, the operator mounts the counterweight 57 on the base 22 (step S7).

Next, the operator holds the sill 11 in the holding unit 12 (step S8). In this step, the worker performs the relative positioning of the sill 11 and the holding portion 12 with reference to the position of the mark attached to the sill 11.

Next, the operator adjusts the posture of the holding portion 12 (step S9). In this step, the operator adjusts the posture of the holding portion 12 so that the sill 11 becomes horizontal by appropriately moving the tilt table and the roll table of the second adjusting portion 36 while visually checking the posture measuring portion 16.

Next, the operator adjusts the height of the holding portion 12 (step S10). In this step, the operator moves the Z-axis table of the first adjusting unit 35 appropriately so that the sensing unit of the height detecting unit 20 senses the horizontal laser beam 70 emitted from the laser striping machine 60.

Next, the operator adjusts the horizontal surface position of the holding part 12 (step S11). In this step, the operator adjusts the horizontal position of the holding portion 12 so that the wires 52 are positioned at the curved corner portions 49 of the respective index members 46 by appropriately moving the X-axis table and the Y-axis table of the first adjusting portion 35 and the deflecting table of the second adjusting portion 36 while visually checking the relative positions of the 2 wires 52 and the pair of index members 46. Fig. 7 is a plan view showing a positional relationship between the pair of indicator members and 2 wires before the horizontal position of the holding portion is adjusted, and fig. 8 is a plan view showing a positional relationship between the pair of indicator members and 2 wires after the horizontal position of the holding portion is adjusted. As shown in fig. 7, before the horizontal position of the holding portion 12 is adjusted, the positions of the pair of indicator members 46 are shifted from the positions of the 2 wires 52. On the other hand, after the horizontal position of the holding portion 12 is adjusted, the piano wires 52 corresponding to the curved corner portions 49 of the pair of indicator members 46 are positioned.

In this way, the positioning of the sill 11 is completed.

Next, as shown in fig. 9, the operator attaches a plurality of brackets 73 to the wall surface 71 of the building facing the hoistway (step S12). The bracket 73 is a member for fixing the sill 11. In the present embodiment, the sill 11 is fixed using 3 brackets 73 as an example. In this step, the worker adjusts the mounting position of the bracket 73 in accordance with the position of the sill 11 positioned as described above. The bracket 73 is fixed to the wall surface 71 by an anchor bolt or the like, not shown.

Next, the operator fixes the sill 11 and the plurality of brackets 73 (step S13). In this work, the fixing of the sill 11 is completed.

Next, the operator releases the holding unit 12 (step S14). In this step, the operator removes the fastener 28 of the holding portion 12 and rotates the second clamping member 27 around the fulcrum portion 31, thereby opening the storage space 30 of the first clamping member 26.

Next, the operator removes the sill attachment device 10 from the sill 11 while paying attention to the fact that the first clamping member 26 of the holding portion 12 does not collide with the sill 11 (step S15).

Thus, the mounting work of the sill 11 is completed.

The sill mounting device 10 according to the first embodiment includes: a holding portion 12 that holds the sill 11; and a positioning mechanism 14 that positions the sill 11 by moving the holding portion 12. Therefore, the worker who performs the sill attachment operation can adjust the position of the sill 11 without hitting the sill 11 with a hammer. This enables the position of the sill 11 to be adjusted more easily than in the conventional case. As a result, the time required for the sill mounting work can be shortened.

The positioning mechanism 14 is configured to position the sill 11 by moving the holding unit 12 in each of the X-axis direction, the Y-axis direction, the Z-axis direction, the rolling direction, the pitching direction, and the yawing direction. Therefore, the position of the sill 11 can be adjusted with high accuracy in each direction of 6 degrees of freedom. Further, since the position of the sill 11 held by the holding portion 12 can be adjusted in one direction or 2 directions, it is possible to suppress interference with position adjustment in different directions. The positioning mechanism 14 may be configured to position the sill 11 by moving the holding portion 12 in at least one direction in a direction of 6 degrees of freedom.

The positioning mechanism 14 is configured to include a first adjusting portion 35 and a second adjusting portion 36 that adjust the position of the sill 11 held by the holding portion 12 in different directions. Therefore, the position of the sill 11 held by the holding section 12 can be adjusted for each of the moving directions of the 3 tables included in the first adjusting section 35 and the moving directions of the 3 tables included in the second adjusting section 36.

The first adjusting unit 35 can adjust the position of the sill 11 held by the holding unit 12 in the X-axis direction, the Y-axis direction, and the Z-axis direction, and the second adjusting unit 36 can adjust the position of the sill 11 in the roll direction, the pitch direction, and the yaw direction. Thereby, the position adjustment of the sill 11 in the X-axis direction, the Y-axis direction, and the Z-axis direction, and the position adjustment of the sill 11 in the rolling direction, the pitching direction, and the yawing direction can be performed without interfering with each other.

The second adjusting part 36 is disposed at a position closer to the holding part 12 than the first adjusting part 35. Thus, when the position of the sill 11 is adjusted by moving the 3 tables included in the second adjustment unit 36, the position (posture) of the sill 11 changes in the vicinity of the movement center axis (rotation axis) of each table. Therefore, as compared with the case where the second adjustment portion 36 is disposed at a position farther from the holding portion 12 than the first adjustment portion 35, the position (posture) of the sill 11 by the second adjustment portion 36 can be easily adjusted.

The sill mounting device 10 is configured to include a posture measuring unit 16 that measures the posture of the sill 11 held by the holding unit 12. This enables the positioning operation of the sill 11 to be performed while the posture measuring unit 16 confirms the posture of the sill 11.

The sill mounting device 10 is configured to include a relative position confirmation unit 18, and the relative position confirmation unit 18 confirms the relative position of the wire 52 hanging from the ceiling of the hoistway of the elevator and the sill 11 held by the holding unit 12. This makes it possible to easily center the sill 11 with reference to the position of the piano wire 52.

The sill-mounting device 10 is configured to include a positional deviation suppressing unit 58 for suppressing a positional deviation of the base 22. This can prevent the position of the base 22 from being inadvertently displaced during the positioning operation of the sill 11. The sill-mounting device 10 can be provided without fixing anchors, screws, and the like to a building or other structure. Therefore, damage to the building or other structure can be avoided, and the time required for installation and removal of the sill attachment device 10 can be shortened.

The base 22 is provided on the floor 19 of the building by a plurality of legs 56 whose lengths can be adjusted. Thus, the base 22 can be horizontally disposed even on the floor 19 having irregularities or steps. Further, the posture of the entire sill attachment apparatus 10 is roughly adjusted by the plurality of leg portions 56 that can be adjusted in length, while the posture of the sill 11 is finely adjusted by the first adjustment portion 35 and the second adjustment portion 36 provided in the positioning mechanism 14, so that a large allowable range in which the position of the sill 11 can be adjusted can be secured.

The sill-mounting device 10 is configured to include a height detection unit 20, and the height detection unit 20 detects that the sill 11 held by the holding unit 12 is disposed at a predetermined height from the floor 19 of the building. This makes it possible to easily adjust the height of the sill 11.

In the sill mounting method of the first embodiment, after the sill 11 is positioned by the sill mounting device 10, the sill 11 is fixed to the wall surface 71 of the building by the bracket 73. This allows the sill 11 to be positioned without causing interference between the positions of the sill 11 and the bracket 73. Further, the sill 11 can be fixed at a desired position without hammering the sill 11 or the bracket 73 with a hammer.

< second embodiment >

Fig. 10 is a view of the sill-mounting device of the second embodiment as viewed from the side of the hoistway.

The sill mounting device 10A of the second embodiment is different from the sill mounting device 10 of the first embodiment in the configuration of a relative position confirmation part 18A for confirming the relative position of the sill 11 held by the holding part 12 with respect to the measurement reference in the hoistway 51 of the elevator. The relative position confirmation unit 18A is constituted by a pair of laser position measurement units 75. The pair of laser position measuring units 75 are disposed at a predetermined interval in the Y-axis direction when the sill attachment device 10A is installed in the opening 67 of the elevator. The pair of laser position measuring units 75 are attached to the sill mounting device 10A instead of the pair of index members 46 described above.

In the second embodiment, instead of the 2 steel wires 52, a pair of laser plumbs 76 are provided at the bottom of the hoistway 51 of the elevator, and vertical laser beams 77 are emitted from the laser plumbs 76. Thereby, 2 vertical laser beams 77 are emitted from the bottom of the elevator shaft 51 toward the top. The 2 vertical laser beams 77 are laser beams emitted so as to have the same positional relationship as the 2 wires 52, and correspond to measurement standards in the hoistway 51 of the elevator. That is, the vertical laser beam 77 is processed into a reference core equivalent to the piano wire 52.

When the sill mounting work is performed using the sill mounting device 10A of the second embodiment, the horizontal position of the holding portion 12 is adjusted as follows in the above-described step S11 (see fig. 6).

First, the operator moves the X-axis table and the Y-axis table of the first adjustment portion 35 and the swing table of the second adjustment portion 36 as appropriate so that the pair of laser position measurement portions 75 receive the 2 vertical laser beams 77 emitted from the pair of laser vertical devices 76 at the same time.

Next, the operator appropriately moves the X-axis table and the Y-axis table of the first adjustment portion 35 and the deflecting table of the second adjustment portion 36 so that the light receiving position of the vertical laser beam 77 in each laser position measuring portion 75 becomes a predetermined position.

According to the second embodiment, the following effects can be obtained.

In the case where the wire 52 is used as a measurement reference in the hoistway 51 of the elevator, the wire 52 may prevent the material from being carried into the hoistway 51. On the other hand, if the vertical laser beam 77 is used instead of the piano wire 52 as a measurement reference in the hoistway 51 of the elevator, it is possible to remove an obstacle at the time of carrying in the equipment. Further, the wire 52 may not be used as a stable reference core because it is shaken by the wind blown into the ascending/descending duct 51. On the other hand, the vertical laser light 77 is not affected by wind, and therefore can be used as a stable reference core at all times.

< third embodiment >

Fig. 11 is a view of the sill-mounting device of the third embodiment as viewed from the top side of the hoistway. The sill mounting device 10B of the third embodiment is different from the sill mounting device 10 of the first embodiment in the configuration of a relative position confirmation section 18B for confirming the relative position of the sill 11 held by the holding section 12 with respect to the measurement reference in the elevator hoistway 51. The relative position confirmation unit 18B is constituted by a pair of laser distance measurement units 80. The laser distance measuring unit 80 emits a laser beam 81 for distance measurement toward the object, and receives the laser beam reflected from the object, thereby measuring the distance from the laser distance measuring unit 80 to the object. The distance as a result of measurement by the laser distance measuring unit 80 is displayed on a display unit (not shown) included in the laser distance measuring unit 80 by a numerical value.

When the sill attachment device 10B is installed in the opening 67 of the elevator, the pair of laser distance measuring units 80 emit laser beams 81 for measuring distance toward the pair of (2) guide rails 82. The pair of laser distance measuring units 80 is attached to the sill-mounting device 10A in place of the pair of indicator members 46. On the other hand, the pair of guide rails 82 are guide rails for guiding the lifting of the elevator car in the lifting path 51. The pair of guide rails 82 are fixed to a wall surface, a steel frame, or the like of the ascending/descending duct 51 by using corresponding rail brackets 83. In the third embodiment, a pair of guide rails 82 is used as a reference for measurement in the hoistway 51 of the elevator.

When the sill mounting work is performed using the sill mounting device 10B of the third embodiment, the horizontal position of the holding portion 12 is adjusted as follows in the above-described step S11 (see fig. 6).

First, the operator moves the X-axis table and the Y-axis table of the first adjusting portion 35 and the deflecting table of the second adjusting portion 36 as appropriate so that 2 laser beams 81 emitted from the pair of laser ranging portions 80 are simultaneously irradiated to the pair of guide rails 82.

Next, the operator adjusts the positions of the sills 11 by appropriately moving the X-axis table and the Y-axis table of the first adjusting section 35 and the swing table of the second adjusting section 36 while visually checking the distance from one laser distance measuring section 80 to the guide rail 82 (hereinafter, referred to as a "first distance") and the distance from the other laser distance measuring section 80 to the guide rail 82 (hereinafter, referred to as a "second distance"), so that the first distance and the second distance are the same distance.

In the third embodiment, the steel wire 52 is not used as a measurement reference in the hoistway 51 of the elevator, and therefore the same effects as those of the second embodiment can be obtained. The pair of laser distance measuring units 80 may be attached to the pair of guide rails 82 instead of being attached to the sill-attaching device 10B. In this case, the laser beam 81 emitted from the laser distance measuring unit 80 attached to the pair of guide rails 82 may be irradiated to the holding unit 12 or the sill 11 held by the holding unit.

< fourth embodiment >

Fig. 12 is a view of the sill mounting device of the fourth embodiment as viewed from the Y-axis direction, and fig. 13 is a view of the sill mounting device of the fourth embodiment as viewed from the X-axis direction.

The sill mounting device 10C according to the fourth embodiment is different from the sill mounting device 10 according to the first embodiment in that a forward tilting prevention portion 90 is provided instead of the counterweight 57, in that the counterweight 57 for preventing forward tilting is not mounted on the base 22.

The forward-tilt preventing portion 90 includes: a pair of support columns 91 fixed to the base 22 and rising from the base 22; a horizontal bar 92 supported by a pair of support posts 91; 2 bottle jacks 93 provided at one end and the other end in the longitudinal direction of the horizontal rod 92; and pads 94 mounted to the bottom surfaces of the respective bottle jacks 93.

When the sill mounting work is performed using the sill mounting device 10C of the fourth embodiment, the left and right pads 94 are brought into contact with the wall surface 71 when the sill mounting device 10C is installed in step S4. Thereby, the sill-mounting device 10C is brought into a state of being leaned against the wall surface 71 via the forward tilting prevention portion 90. Therefore, the weight of the sill attachment 10C is received by the wall surface 71, and the entire sill attachment 10C can be prevented from tilting forward. Therefore, the step of step S7 (see fig. 6) described above is not required. The forward tilting prevention unit 90 is configured to include a pair of bottle jacks 93. The bottle jack 93 is capable of adjusting the distance from the wall surface 71 to the horizontal rod 92 by extending and contracting in the X-axis direction in a state where the pad 94 is pressed against the wall surface 71. Therefore, by changing the amount of expansion and contraction of the pair of bottle jacks 93, even when the wall surface 71 has irregularities, the inclination angle in the front-rear direction (X-axis direction) of the sill-mounting device 10C can be adjusted to a desired angle.
