Subsequently, a weight frame assembling method according to the first embodiment will be described using FIGS. 5 to 9.
5 to 9 are diagrams showing an example of the weight frame assembling method according to the first embodiment.

  In FIG. 5, a view from above of the spacer 28 is shown. The left direction of the drawing is the front direction of the weight frame 21. The upward direction of the paper surface is the rightward direction of the weight frame 21.

  Here, an example in the elevator 1 in which the thickness t2 corresponds to the width of the gap between the counterweight 9 and each of the pair of counterweight guide rails 7 is shown.

  A worker who assembles the weight frame 21 in the pit 3 performs work of a standing frame arrangement process. The standing frame arrangement process includes a spacer attaching process.

  In the spacer attachment process, the operator attaches one of the pair of spacer elements 30 to the front side of the side of the stand 22. At this time, the second side surface 33 is directed to the rear of the weight frame 21. The worker attaches the other of the pair of spacer elements 30 to the rear of the side of the stand 22. At this time, the second side surface 33 is directed to the front of the weight frame 21. The worker attaches the pair of spacer elements 30 as the spacers 28 to the side surface of the stand 22 by bringing the second side surfaces of each of the pair of spacer elements 30 together.

  The second regions 35 of each of the pair of spacer elements 30 are aligned with each other at the longitudinal center of the side surface of the stand 22. The paired second regions 35 form a region of constant thickness t2. The length in the front-rear direction of the region is twice the distance d2. That is, the length in the front-rear direction of the region is longer than the thickness T of the counterweight guide rail 7.

  In the standing frame arrangement step, the operator causes the side surface of the standing frame 22 to which the spacer 28 is attached to face the counterweight guide rail 7. The worker aligns a region of constant thickness t 2 of the spacer 28 with the counterweight guide rail 7. Thereby, the spacer 28 keeps the width of the gap between the side surface of the standing frame 22 and the counterweight guide rail 7 constant by the region of thickness t2.

  6 to 9, the weight frame 21 assembled in the pit 3 is shown. The upward direction of the paper is vertically upward. The left direction of the paper surface is the left direction of the weight frame 21.

  As shown in FIG. 6, the worker vertically arranges each of the pair of upright frames 22 as an upright frame arrangement step. At this time, the width of the gap between each side surface of the pair of upright frames 22 and each of the pair of counterweight guide rails 7 is kept constant by the spacer 28. The operator fixes each of the pair of upright frames 22 to each of the pair of counterweight guide rails 7 by means of the lashing belts 41.

  Next, as shown in FIG. 7, the worker attaches the upper frame 23 to each of the pair of upright frames 22 as an upper frame attachment process. At this time, each of the pair of upright frames 22 is fixed to each of the pair of counterweight guide rails 7 by the lashing belt 41 in a state of being erected vertically. The width of the gap between the side surface of each of the pair of upright frames 22 and each of the pair of counterweight guide rails 7 is kept constant by the spacer 28.

  Next, as shown in FIG. 8, the worker moves each of the pair of standing frames 22 vertically upward as a standing frame moving step.

  In the standing frame moving step, the worker removes the lashing belt 41 from each of the pair of standing frames 22. The worker attaches one end of the rope 42 to the upper frame 23. The operator lifts the upper frame 23 by operating a lifting device such as a chain block (not shown) provided at the other end of the rope 42. The pair of upright frames 22 attached to the upper frame 23 is lifted together with the upper frame 23. The spacers 28 attached to the pair of upright frames 22 are lifted together with the pair of upright frames 22. At this time, the spacers 28 are lifted while keeping the width of the gap between each side surface of the pair of upright frames 22 and each of the pair of counterweight guide rails 7 constant.

  Next, as shown in FIG. 9, the worker places the stand 29 by placing the open end of the cap 37 on the upper end of the counterweight buffer 16 as a stand arrangement step. At this time, the worker arranges the pedestal 29 in the direction in which the top plate 38 extends in the left-right direction of the weight frame 21.

  Next, the worker carries out the work of the lower frame attachment process. The lower frame attaching process includes a lower frame disposing process and a spacer removing process.

  In the lower frame disposing step, the worker places the lower frame 24 on the upper surface of the top plate 38 of the pedestal 29 disposed at the upper end of the counterweight buffer 16. At this time, the worker passes the holding portion 26 through one of the pair of openings 39. Thereby, the lower surface of the lower frame 24 is aligned with the upper surface of the top plate 38.

  In the lower frame attachment process, the worker attaches the lower frame 24 to each of the pair of upright frames 22. At this time, the width of the gap between each side surface of the pair of upright frames 22 and each of the pair of counterweight guide rails 7 is kept constant by the spacer 28.

  In the spacer removal step, the worker removes one of the pair of spacer elements 30 from the front side of the stand 22. The worker removes the other of the pair of spacer elements 30 from the front side of the stand 22.

Subsequently, an example of a spacer attaching process in the elevator 1 in which the thickness t1 corresponds to the width of the gap between the counterweight 9 and each of the pair of counterweight guide rails 7 will be described using FIG.
FIG. 10 is a view showing an example of a weight frame assembling method according to the first embodiment.

  In FIG. 10, a view from above of the spacer 28 is shown. The left direction of the drawing is the front direction of the weight frame 21. The upward direction of the paper surface is the rightward direction of the weight frame 21.

  In the spacer attachment process, the operator attaches one of the pair of spacer elements 30 to the front side of the side of the stand 22. At this time, the first side surface 32 is directed to the rear of the weight frame 21. The worker attaches the other of the pair of spacer elements 30 to the rear of the side of the stand 22. At this time, the first side surface 32 is directed to the front of the weight frame 21. The worker attaches the pair of spacer elements 30 as the spacers 28 to the side surface of the stand 22 by aligning the first side surfaces of the pair of spacer elements 30 with each other.

  The first regions 34 of each of the pair of spacer elements 30 are aligned with each other at the longitudinal center of the side surface of the stand 22. The pair of combined first regions 34 form a region of constant thickness t1. The length in the front-rear direction of the region is twice the distance d1. That is, the length in the front-rear direction of the region is longer than the thickness T of the counterweight guide rail 7.

  In the standing frame arrangement step, the operator causes the side surface of the standing frame 22 to which the spacer 28 is attached to face the counterweight guide rail 7. The worker aligns a region of constant thickness t 1 of the spacer 28 with the counterweight guide rail 7. Thereby, the spacer 28 keeps the width of the gap between the side surface of the standing frame 22 and the counterweight guide rail 7 constant by the region of thickness t1.

  As described above, the weight frame assembly support apparatus 27 according to the first embodiment includes the spacer 28. The spacer 28 is attached to the side of the stand 22 of the weight frame 21 of the counterweight 9. The spacer 28 keeps the width of the gap between the counterweight guide rail 7 facing the side and the side constant. The spacer 28 moves together with the upright frame 22 when the upright frame 22 in a state in which the lower frame 24 of the weight frame 21 is not attached in the assembly of the weight frame 21 moves in the vertical direction.

  The weight frame assembling method according to the first embodiment includes a standing frame arranging process, an upper frame attaching process, a standing frame moving process, and a lower frame attaching process. In the standing frame arranging step, the standing frame 22 of the weight frame 21 of the counterweight 9 has a constant width of the gap between the counterweight guide rail 7 facing the side surface of the standing frame 22 and the side surface by the spacer 28. It is placed vertically standing to keep. The spacer 28 is attached to the side surface. In the upper frame attaching process, the upper frame 23 of the weight frame 21 is attached to the erected upright frame 22. In the standing frame moving step, the standing frame 22 to which the upper frame 23 is attached is moved vertically upward together with the spacer 28. At this time, the width of the gap between the counterweight guide rail 7 and the side surface of the standing frame 22 is kept constant by the spacer 28. In the lower frame attaching process, the lower frame 24 of the weight frame 21 is attached to the upright frame 22 moved vertically upward.

  The spacer 28 keeps the width of the gap between the side surface of the stand 22 and the counterweight guide rail 7 constant even when the stand 22 is moved in the vertical direction to attach the lower frame 24 to the stand 22. Keep it Thus, the worker can assemble the weight frame 21 while keeping the width of the gap constant. That is, the worker does not have to adjust the width of the gap after assembling the weight frame 21. Therefore, the worker can assemble the weight frame 21 easily and precisely in the hoistway 2.

  The spacer 28 also includes a pair of spacer elements 30. The pair of spacer elements 30 are separable from one another. The bottom surface 31 of each of the pair of spacer elements 30 is attached to the side surface of the upright frame 22. Each of the pair of spacer elements 30 has a first region 34. The first region 34 is a region where the distance d1 from the first side surface 32 is at least half the thickness T of the counterweight guide rail 7. The first side surface 32 is a side surface perpendicular to the bottom surface 31. The thickness t1 from the bottom surface 31 of the first region 34 is constant.

  The standing frame arrangement process includes a spacer attaching process. In the spacer attaching process, one of the pair of spacer elements 30 is attached to the front side of the side surface of the upright frame 22. In the spacer attaching process, the other of the pair of spacer elements 30 is attached to the rear side of the side surface of the upright frame 22. The lower frame attachment step includes a spacer removal step. In the spacer removing step, one of the pair of spacer elements 30 is removed from the front side of the stand 22. In the spacer removing step, the other of the pair of spacer elements 30 is removed from the rear side of the stand 22.

  In the spacer attachment process, the first side surfaces 32 of each of the pair of spacer elements 30 are aligned with one another. The first region 34 of each of the pair of spacer elements 30 forms a region of constant thickness t1. Thus, the pair of spacer elements 30 maintain the width of the gap between the side surface of the standing frame 22 and the counterweight guide rail 7 at a constant width corresponding to the constant thickness t1. The area is a combined area of the first side surfaces 32 that are the ends of the pair of spacer elements 30. In the spacer removing step, the worker removes the spacer element 30 attached to the front side of the counterweight guide rail 7 from the front side of the counterweight guide rail 7. The operator removes the spacer element 30 attached to the rear side of the counterweight guide rail 7 from the rear side of the counterweight guide rail 7. Thus, after assembling the weight frame 21, the worker can easily remove the spacer 28.

  Each of the pair of spacer elements 30 has the same configuration as each other. Thus, even when a plurality of spacers 28 are used, it is not necessary to consider the combination of the pair of spacer elements 30. Thereby, in the weight frame assembly support device 27, management of parts becomes easy.

  In addition, each of the pair of spacer elements 30 has a second region 35. The second region 35 is a region in which the distance d2 from the second side surface 33 is at least half of the thickness T of the counterweight guide rail 7. The second side surface 33 is a side surface perpendicular to the bottom surface 31. The thickness t2 from the bottom surface 31 of the second region 35 is constant. The thickness t2 from the bottom surface 31 of the second region 35 is thinner than the thickness t1 from the bottom surface 31 of the first region 34.

  In the assembly of the weight frame 21, the second sides of each of the pair of spacer elements 30 are brought together. The second region 35 of each of the pair of spacer elements 30 forms a region of constant thickness t1. Thereby, the pair of spacer elements 30 keep the width of the gap between the side surface of the standing frame 22 and the counterweight guide rail 7 at a constant width corresponding to the constant thickness t2. Therefore, the spacer 28 can be used for both the elevator 1 whose width corresponds to the thickness t1 and the elevator 1 whose width corresponds to the thickness t2. Therefore, the versatility of the weight frame assembly support device 27 is enhanced.

  In addition, the weight frame assembly support device 27 includes a pedestal 29. The pedestal 29 has a cap 37 and a top plate 38. The lower end of the cap 37, which is one end in the axial direction, is an open end. The cross-sectional shape of the lower end according to a plane perpendicular to the axial direction of the cap 37 internally includes the shape of the horizontal cross-section of the upper end of the counterweight buffer 16. The top plate 38 is provided at an upper end which is the other axial end of the cap 37. An upper surface which is a surface opposite to the cap 37 of the top plate 38 is a bearing surface perpendicular to the axial direction of the cap 37.

  In addition, the weight frame assembling method includes a pedestal arrangement step. The pedestal has a cap 37 and a top 38. One axial end of the cap 37 is an open end. The top plate 38 is provided at the other axial end of the cap 37. The upper surface which is a surface on the opposite side to the cap 37 of the top plate 38 is a bearing surface perpendicular to the axial direction. In the pedestal arrangement step, the pedestal 29 is arranged by covering the open end of the cap 37 of the pedestal 29 on the upper end of the counterweight buffer 16. The lower frame attachment process includes a lower frame arrangement process. In the lower frame disposing step, the lower frame 24 not attached to the upright frame 22 is disposed on the receiving surface of the pedestal 29 disposed at the upper end of the counterweight buffer 16.

  As a result, the operator can stably attach the lower frame 24 to the upright frame 22 while the weight frame 21 is adjusted to the position above the counterweight buffer 16. Therefore, the worker can assemble the weight frame 21 in the hoistway 2 more easily and precisely.

  Also, an opening 39 is provided in the top plate 38. The opening 39 is provided at a position away from the center of the top plate 38 by the distance x between the holding portion 26 and the center of the lower surface of the lower frame 24. The holding portion 26 is a portion that protrudes from the lower surface of the lower frame 24 of the weight frame 21. The opening 39 penetrates from the receiving surface to the cap 37 side.

  In the arrangement of the lower frame 24 on the pedestal 29, the holding portion 26 is passed through the opening 39. Thus, the lower surface of the lower frame 24 is aligned with the upper surface of the top plate 38. Therefore, even when the holding portion 26 is on the lower surface of the lower frame 24, the worker can stably arrange the lower frame 24 on the upper surface of the top plate 38.

  The cap 37 may have a prismatic shape such as a hexagonal prism or an octagonal prism, for example. This makes the cap 37 easy to manufacture.

  The lower frame 24 may have a portion protruding from the lower surface in addition to the holding portion 26. The portion may be, for example, a bolt for fixing the weight block 20 or the other portion. At this time, when the lower frame 24 is placed on the upper surface of the pedestal 29, an opening through which the relevant portion passes is provided in the top plate 38.

  Each of the pair of openings 39 may be a groove extending to the left and right ends. Each of the pair of openings 39 may be a plurality of holes. The pedestal 29 can be used for a plurality of elevators in which the holding portion 26 is provided at different positions on the lower surface of the lower frame 24. Therefore, the versatility of the weight frame assembly support device 27 is enhanced.
