  As shown in FIGS. 1 and 2, in the elevator hoistway H, a pair of guide rails 4 for guiding a car (not shown) are attached to the wall 1 of the building via rail brackets 5. The pair of guide rails 4 are arranged in the left-right direction and extend in the vertical direction (vertical direction). The guide rail 4 is attached to the rail bracket 5 with a bolt 5a.

  Above the hoistway H, a floor 2 of the machine room extends in the horizontal direction (front-rear direction and left-right direction), and a machine beam 3 extending in the front-rear direction is provided. In the present embodiment, in FIG. 1, the machine beam 3 on the left side is displaced from the wall 1 on the left side to the right, and the machine beam 3 on the right side is displaced from the wall 1 on the right side to the left. The floor 2 and the machine beam 3 are examples of building structures.

  The floor 2 is provided with a hole 2a and two holes 2b that penetrate the floor 2 in the vertical direction. The hole 2a is a hole through which a rope for suspending the car passes. The two holes 2b are arranged in the left-right direction. The left hole 2b is provided between the left wall 1 and the left guide rail 4 and between the left wall 1 and the left machine beam 3. The right hole 2b is provided between the right wall 1 and the right guide rail 4 and between the right wall 1 and the right machine beam 3. The hole 2b is an example of an opening. Note that the hole 2b is provided together with the hole 2a in the initial process of the work of moving the guide rail 4 as an example. Further, as shown in FIG. 2, the hole 2b extends in the front-rear direction.

  The guide rail moving device 10 includes a base 11, a beam 12, a jack 13, and a column 14.

  The base 11 extends in the left-right direction so as to bridge over the two machine beams 3. Both ends of the base 11 are supported on the machine beam 3 via rollers 15, respectively. The roller 15 can roll in the front-back direction on the top surface of the machine beam 3 extending in the front-back direction. The front-back direction is the direction orthogonal to the paper surface in FIG. 1 and the left-right direction in FIG. The base 11 is supported on the machine beam 3 via rollers 15 so as to be movable in the front-rear direction. The front-back direction is an example of the first direction. The roller 15 may also be referred to as a wheel.

  Further, the base 11 is provided with a guide 11 a that projects downward from the base 11 and is adjacent to the machine beam 3, that is, faces the machine beam 3 with a gap. The guide 11a suppresses the displacement of the base 11 with respect to the machine beam 3. The guide 11a may also be referred to as a positioning member.

  The beam 12 is provided apart from the base 11 in the upper direction and extends in the left-right direction. The left and right ends 12a of the beam 12 are respectively located above the holes 2b.

  As shown in FIG. 2, the guide rail moving device 10 has two sets of a base 11, a beam 12, a jack 13, and a roller 15 in the front and rear.

  As shown in FIG. 1, columns 14 are provided at the left and right ends 12a of the beam 12, respectively. Further, as shown in FIG. 2, the column 14 is fixed in a state of being sandwiched between the front and rear beams 12. As shown in FIGS. 1 and 2, the column 14 extends downward from the end 12 a and penetrates a hole 2 b provided in the floor 2. The lower end 14a of the column 14 is located between the upper end 4a of the guide rail 4 and the wall 1, and the lower end 14a is connected to the upper end 4a of the guide rail 4 via the bolt 16. The upper end 4a is an example of an upper part. The column 14 is an example of a hanging member, and may be referred to as a hanging member. The bolt 16 may also be referred to as a connecting member.

  A jack 13 is provided between the base 11 and the beam 12. The jack 13 can be switched between a shortened state in which it is contracted in the vertical direction and an extended state in which it is extended in the vertical direction. As shown in FIGS. 3 and 4, the bolt 5 a (not shown in FIGS. 3 and 4, see FIGS. 1 and 2) is removed, and the guide rail 4 and the rail bracket 5 are disengaged from each other. When the beam extends, the beam 12 moves upward with respect to the base 11, and accordingly, the column 14 fixed to the beam 12 and the guide rail 4 fixed to the column 14 move upward. On the other hand, when the jack 13 is shortened from the state shown in FIGS. 3 and 4, the beam 12 moves downward with respect to the base 11, and accordingly, the column 14 fixed to the beam 12 and the column 14 fixed to the column 14 are fixed. The guide rail 4 moves downward. In this way, the jack 13 can move the beam 12 upward with respect to the base 11. The jack 13 is an example of a lifter, and the base 11 is an example of a movable member.

  As is clear from a comparison of FIGS. 2 and 4, as the roller 15 rolls, the base 11, the guide rail moving device 10, and thus the guide are moved to the extent that the column 14 can move in the hole 2b extending in the front-rear direction. The guide rail 4 coupled to the rail moving device 10 via the bolt 16 can move in the front-rear direction. The hole 2b is provided according to the moving range of the guide rail 4.

  In the state shown in FIGS. 3 and 4, a spacer 17 is interposed between the base 11 and the beam 12. The spacer 17 holds the position of the beam 12 with respect to the base 11. The spacer 17 can also be called a holding member or a fixing member.

  FIG. 5 shows a procedure of the work for moving the guide rail 4. The worker first provides the hole 2b in the floor 2 (S10). In S10, the worker, for example, provides the hole 2b so that the specifications do not interfere with the moving column 14. S10 is an example of the first step.

  Next, the worker sets the guide rail moving device 10 to the state shown in FIGS. 1 and 2 (S11). In S11, the operator assembles the guide rail moving device 10 in a state where, for example, the column 14 penetrates the hole 2b and the base 11 is placed on the machine beam 3 via the roller 15. S11 is an example of the second step.

  Next, the worker connects the column 14 (the hanging member) to the guide rail 4 (S12). S12 is an example of the third step.

  Next, the worker removes the guide rail 4 from the rail bracket 5 by releasing the connection between the guide rail 4 and the rail bracket 5 with the bolt 5a (S13).

  Next, the worker moves the beam 12 upward with respect to the base 11 by extending the jack 13 as shown in FIG. That is, jack-up is executed (S14). By S14, the beam 12, the column 14, and the guide rail 4 move upward with respect to the base 11. Thereby, although not shown, it is possible to suppress the lower end of the guide rail 4 from interfering with other structures in the pit. S14 is an example of the fourth step. The operator can interpose the spacer 17 between the base 11 and the beam 12 after S14.

  Next, as shown in FIG. 4, the worker rolls the roller 15 forward on the top surface of the machine beam 3 to move the base 11, the guide rail moving device 10, and the guide rail moving device. The guide rail 4 coupled to 10 is moved forward (S15). S15 is an example of the fifth step.

  Next, the operator moves the beam 12 downward with respect to the base 11 by shortening the jack 13 when the guide rail 4 moves to a new transfer position. That is, jack down is executed (S16). By S16, the beam 12, the column 14, and the guide rail 4 move downward with respect to the base 11. If the spacer 17 is interposed between the base 11 and the beam 12 in S14, the worker removes the spacer 17 before executing S16. S16 is an example of the sixth step.

  Next, the worker attaches the guide rail 4 to the rail bracket provided at the new transfer position via, for example, a bolt (S17).

  As described above, in the present embodiment, the guide rail moving device 10 includes the base 11, the beam 12 (movable member), and the jack provided on the machine beam 3 (building structure) above the guide rail 4. 13 (lifter) and a column 14 (hanging member) fixed to the beam 12 and penetrating a hole 2b provided in the floor 2 (building structure) and coupled to the guide rail 4. According to such a configuration, for example, when the operator removes the guide rail 4 and transports it without using the guide rail moving device 10, or when the old guide rail 4 is removed and the new guide rail 4 is placed in another place. The guide rail 4 can be moved relatively easily by using the guide rail moving device 10 as compared with the case where the guide rail 4 is attached. In other words, the guide rail moving device 10 can reduce the labor required for the operator to move the guide rails 4.

  Further, in the present embodiment, the guide rail moving device 10 has a roller 15 that can move on the machine beam 3 in the front-rear direction (first direction). With such a configuration, for example, an operator can relatively easily move the base 11, the guide rail moving device 10, and eventually the guide rail 4 in the front-rear direction.

  Further, in the present embodiment, the guide rail moving device 10 moves in the front-back direction on the existing floor 2 or machine beam 3 (building structure). According to such a configuration, for example, as compared with the case where the movement path of the guide rail moving device 10 is provided separately from the floor 2 and the machine beam 3 which are located above the guide rail 4, the guide rail 4 operated by the operator is moved. It is possible to further reduce the labor of moving work.

The guide rail moving system 100 includes an auxiliary moving device 20 and an upper device such as the guide rail moving devices 10 and 10A that supports and moves the upper end 4a of the guide rail 4. The lower end 4b is an example of a lower part, and the upper end 4a is an example of an upper part. The lower portion may be a portion lower than the upper portion, and the upper portion may be a portion above the lower portion. Therefore, the upper portion is not limited to the upper end 4a, and the lower portion is not limited to the lower end 4b.

  The auxiliary moving device 20 holds the lower ends 4b of the pair of guide rails 4 and can move in the front-rear direction along the pit 6. The auxiliary movement device 20 has a carriage 21 and two rollers 22. The dolly 21 has two vertical members 21a, two horizontal members 21b, and two mounting members 21c.

  The vertical member 21a extends in the vertical direction. The dolly 21 has two vertical members 21a arranged in the left-right direction. The lateral members 21b extend in the left-right direction and are separated from each other in the vertical direction. The horizontal member 21b is bridged between the two vertical members 21a. That is, the two vertical members 21a and the two horizontal members 21b constitute a quadrangular or ladder-shaped frame. The mounting member 21c is fixed to each of the vertical members 21a and extends in the front-rear direction. The right mounting member 21c is connected to the right guide rail 4, and the left mounting member 21c is connected to the left guide rail 4. The mounting members 21c are respectively adjacent to the left or right of the corresponding guide rails 4 and are connected to the guide rails 4 via rail clips 21d. The rail clip 21d may also be referred to as a coupling member. Further, as shown in FIG. 9, the lower end of the vertical member 21a has an L-shape when viewed in the left-right direction. The roller 22 is attached to the bottom wall extending in the front-rear direction at the lower end of the vertical member 21a. The roller 22 can roll on the pit 6 in the front-rear direction.

  The worker attaches the auxiliary moving device 20 to the lower end 4b of the guide rail 4 in a state where the guide rail 4 is moved upward by the jack 13 (lifter).

  With such a configuration, the position and posture of the lower end 4b (lower part) of the guide rail 4 are more stable, and the worker can move the guide rail 4 more smoothly.

  In addition, in the present embodiment, the lower ends 4b of the two guide rails 4 can be supported by the single auxiliary movement device 20 having the frame-shaped portion. With such a configuration, the postures of the two guide rails 4 are more stable, and the operator can move the guide rails 4 more smoothly.

[Fourth Embodiment]
FIG. 10 is a front view of the guide rail moving device 10B of this embodiment. The guide rail moving device 10B does not have the rollers 15 and 15A. Instead of the rollers 15 and 15A, a sheet-shaped sliding member 18 is interposed between the base 11 and the floor 2. The sliding member 18 is made of a relatively slippery material such as a fluorine-based synthetic resin material.

  With such a configuration, for example, a structure in which the base 11 slides on the floor 2 can be realized as a simpler structure.

[Modification]
FIG. 11 is a front view showing a rail clip 16A for coupling the guide rail 4 and the column 14 in the modified examples of the guide rail moving devices 10, 10A, 10B of the first to fourth embodiments. As shown in FIG. 11, the guide rail 4 and the column 14 may be joined by a rail clip 16A instead of the bolt 16. The rail clip 16A is an example of a connecting member. With such a configuration, for example, an operator does not need to provide the guide rail 4 with a through hole for penetrating the bolt 16. That is, the labor of the worker can be further reduced.

[Fifth Embodiment]
FIG. 12 is a side view of the guide rail moving device 10C of this embodiment. The guide rail moving device 10C includes a wire 14A instead of the column 14. A ring 4c with a roller is attached to the upper end 4a of the guide rail 4, and the ring 4c is suspended by a wire 14A suspended in a U shape. Also in this embodiment, the guide rail moving device 10C has two sets of the base 11, the beam 12, the jack 13 (not shown), the roller 15, and the spacer 17 in the front and rear. However, in the present embodiment, the guide rail moving device 10C is provided with the bridge 19 that crosses between the end portions 12a of the beam 12 back and forth on each of the left side and the right side, and the wire 14A is attached to this bridge 19. There is. Both ends of the wire 14A are attached to the bridge 19 with a space in the front and back, and the ring 4c is hooked on the middle portion of the wire 14A. Further, two sets of the wire 14A and the ring 4c are provided at front and back with a space. As a result, the position and posture of the suspended guide rail 4 are more stable.

  According to such a configuration, for example, the guide rail moving device 10C is lighter than the configuration having the column 14, and thus the labor of setting the guide rail moving device 10C by the worker can be reduced. Further, for example, since the wire 14A is thinner than the column 14, the size of the hole 2b can be made smaller, and the rigidity and strength of the floor 2 (building structure) can be easily maintained higher.

  Although the embodiments of the present invention have been illustrated above, the above embodiments are merely examples, and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, combinations, and changes can be made without departing from the spirit of the invention.
