  The hoisting machine lifting jig unit and the hoisting machine lifting method according to the present embodiment are applied to an elevator 1 as shown in FIG. The elevator 1 includes a hoistway 2, a car 3, a counterweight 4, a main rope 5, a hoisting machine 6, a guide rail 7 and a guide rail 8. The raising / lowering direction of the car 3 and the counterweight 4 described below is typically a vertical direction. The hoistway 2 is provided along the vertical direction of the building. The car 3 is connected to the main rope 5 and disposed in the hoistway 2, and the car 3 can be raised and lowered. The car 3 has, for example, a sheave 10 on an upper beam 9 disposed in the upper part in the vertical direction, and the main rope 5 is hung on and supported by the sheave 10. The main rope 5 is hung on the main sheave or the deflector sheave of the hoist 6 provided at the upper part of the hoistway 2, and both ends are fixed to the upper part of the hoistway 2. The main rope 5 has a car 3 on one end and a counterweight 4 on the other end with the hoisting machine 6 interposed therebetween. The drive of the hoisting machine 6 is controlled by a control panel. For example, when a motor (motor) that generates power for moving the car 3 is driven, the main sheave connected to the motor is driven to rotate. The main rope 5 is electrically wound up using the frictional force generated between the main sheave and the main rope 5. The elevator 1 according to the present embodiment is a so-called machine roomless elevator, does not include a machine room above the hoistway 2, and is provided with a hoisting machine 6 at the top of the hoistway 2. The guide rail 7 and the guide rail 8 are provided in the hoistway 2 so as to extend along the raising / lowering direction (vertical direction) of the car 3 and the counterweight 4. The elevator 1 configured as described above, when a call operation is performed by a user via an operation panel or the like, based on the call registration and the current moving direction (lifting direction) of the car 3, The upper machine 6 is driven. Thus, in the elevator 1, the hoisting machine 6 winds up the main rope 5, so that the car 3 moves up and down in the vertical direction in the hoistway 2 and moves to a landing on an arbitrary destination floor. At this time, in the elevator 1, the guide rail 7 and the guide rail 8 guide the raising / lowering movement of the car 3 and the counterweight 4 along the raising / lowering direction.

  And the hoisting machine lifting jig unit 100 which concerns on this embodiment shown in FIGS. 2-5 is installed in the upper part in the hoistway 2 when installing the elevator 1 comprised as mentioned above in a building. This is a jig unit for lifting the hoisting machine 6 to the height of a machine beam (hoisting machine yagura) 11 as a hoisting machine fixing member.

  The elevator 1 is typically installed in the building before the lifting of the hoist 6 when it is installed in the building, but the construction of the guide rail 7 and the guide rail 8 has been completed. 3. The counterweight 4 is not yet installed. Further, in this state, as shown in FIG. 5, the elevator 1 is temporarily installed with various articles such as a scaffold 12 in a space in which the car 3 moves up and down in the hoistway 2.

  Specifically, the hoisting machine lifting jig unit 100 includes a rail guide frame 110, a fixing blanket 120, a rotating mechanism 130, a moving mechanism 140, and a fall prevention guide 150 as hoisting machine lifting jigs. The slide mechanism 160 is provided.

Here, as described above, the guide rails 8 guide the up-and-down movement of the counterweight 4 along the up-and-down direction, and are provided in pairs in the horizontal direction. The rail guide frame 110 is configured in a rectangular frame shape by a plurality of columnar members and a plurality of beam-shaped members, and is disposed between the pair of guide rails 8. The rail guide frame 110 is guided by guide rails 8 at both ends in the horizontal direction. The rail guide frame 110 is connected to the lifting machine 170 via a connecting portion 111 provided at the upper end in the vertical direction. The lifting machine 170 is for generating power for lifting the hoisting machine 6 together with the rail guide frame 110, and engages with a hook (hanging source) 2 b provided on the ceiling 2 a of the hoistway 2.

The lifting machine 170 may include, for example, a manual lifting machine 170a for manually lifting, an electric lifting machine 170b (see FIG. 3 and the like) for electrically lifting, and the like. These may be properly used according to the work situation. The rail guide frame 110 is lifted by the lifting machine 170, so that the hoistway 2 can be raised and lowered while being guided by the guide rail 8. Here, the rail guide frame 110 has a vertically divided structure, but is not limited thereto.

  The fixing blanket 120 is for temporarily fixing the rail guide frame 110 to a predetermined position of the guide rail 8 under a predetermined condition. A total of two fixing blankets 120 are provided at both ends of the rail guide frame 110 in the horizontal direction, one for each pair of guide rails 8. The lifting machine 170 described above is connected to the rail guide frame 110 as described above and is used when lifting the rail guide frame 110. For example, as will be described later, the hoisting machine 6 is placed on the moving mechanism 140. It is also used when mounting. In this case, the lifting machine 170 is in a state of being disconnected from the rail guide frame 110. At this time, the fixing blanket 120 temporarily fixes the rail guide frame 110 at a predetermined position of the guide rail 8 before the connection between the lifting machine 170 and the rail guide frame 110 is released. The fixing blanket 120 is integrally connected to the rail guide frame 110, and the downward movement in the vertical direction is restricted at a predetermined position by a stopper provided on each guide rail 8, so that the rail guide frame 110 is temporarily fixed at a predetermined position of the guide rail 8. Thereby, the rail guide frame 110 is held in a fixed state at a predetermined position of the guide rail 8 even when the connection with the lifting machine 170 is released.

  The rotation mechanism 130 is fixed to the upper part of the rail guide frame 110. The rotating mechanism 130 supports the hoisting machine 6 together with the moving mechanism 140 with respect to the rail guide frame 110 so as to be relatively rotatable. The rotating mechanism 130 supports the hoisting machine 6 together with the moving mechanism 140 so as to be rotatable about the rotation axis X (see FIG. 6) along the vertical direction. The rotation mechanism 130 of the present embodiment includes a turntable 131 (see FIG. 2 and the like), a plurality of ball rollers 132 (see FIGS. 2 and 4 and the like) as rolling elements, a rotating shaft 133 (see FIG. 5 and the like), and the like.

The turntable 131 is connected to the upper part in the vertical direction of the rail guide frame 110 via a support member 134 and the like. The turntable 131 is fixed so that the flat surface of the rectangular plate is substantially horizontal while being connected to the upper part of the rail guide frame 110 in the vertical direction.

  As shown in FIGS. 6, 7, 8, and the like, the ball roller 132 uses a moving table 141 of a moving mechanism 140, which will be described later, mounted on the upper side in the vertical direction of the rotating table 131, with the rotation axis X as the rotation center. It is supported rotatably. The ball roller 132 rotatably supports the moving table 141 on the upper surface in the vertical direction of the rotating table 131. The ball roller 132 of this embodiment is a spherical rolling element. The ball roller 132 is provided between the turntable 131 and the moving table 141 facing the turntable 131 with respect to the vertical direction. The ball roller 132 is provided on one of the rotating table 131 or the moving table 141, here, on the moving table 141 side so as to be able to rotate. A plurality of ball rollers 132 are provided on the surface on the lower side in the vertical direction of the moving table 141 (the surface facing the rotating table 131), here three, and the upper surface in the vertical direction of the rotating table 131 (with the moving table 141 and the moving table 141). It can roll on the opposite surface. Note that the rotation mechanism 130 may be configured to include a bearing or the like arranged in a circle instead of the ball roller 132. Further, the ball roller 132 may be provided on a surface on the upper side in the vertical direction on the turntable 131 side (a surface facing the moving table 141).

  As shown in FIG. 6 and the like, the rotation shaft 133 forms a rotation axis X that is the rotation center of the rotation mechanism 130, that is, the rotation center when the hoisting machine 6 is rotated together with the moving mechanism 140. The rotating shaft 133 is configured by a bolt or the like fixedly connected to the rotating table 131. The rotary shaft 133 is erected so as to protrude upward along the vertical direction from the upper surface of the rotary table 131 in the vertical direction. The rotation shaft 133 is fixed to the turntable 131 at the base end side. On the other hand, the rotating shaft 133 passes through a through hole 141 a formed on the front end side at the approximate center of the movable table 141. The rotating shaft 133 is inserted into the through hole 141a so that the rotating table 131 and the moving table 141 can rotate relative to each other, and a nut is screwed to the tip side. In the rotation mechanism 130, the central axis of the rotation shaft 133 is the rotation axis X.

  Therefore, in the rotating mechanism 130 configured as described above, the ball roller 132 rolls on the rotating table 131 in a state where the moving mechanism 140 (described later) and the hoisting machine 6 are placed on the rotating table 131. As a result, the moving mechanism 140 and the hoisting machine 6 can be rotated relative to the turntable 131 at a predetermined rotation angle with the rotation axis X of the rotation shaft 133 as the rotation center.

  The moving mechanism 140 places the hoisting machine 6 so as to be movable along the horizontal direction. The moving mechanism 140 is provided on the rotating mechanism 130. The moving mechanism 140 according to the present embodiment includes the above-described moving table 141 (see FIGS. 2 and 4 and the like), a bearing 142 (see FIGS. 6 and 8 and the like), and the like. In the following description of the moving mechanism 140, FIGS. 6 to 8 are also referred to as appropriate in addition to FIGS.

  As shown in FIGS. 6, 7, 8, and the like, the movable table 141 is formed in a rectangular plate shape, and a flange portion 141 c is formed on two opposite sides via a stepped portion 141 b. Each flange portion 141 c is substantially parallel to the bottom portion 141 d of the movable table 141. The movable table 141 has the above-described through-hole 141a formed at the approximate center of the bottom 141d. Further, the moving table 141 is provided with two ball rollers 132 on the vertically lower surface of one flange portion 141c and one ball roller 132 on the vertically lower surface of the other flange portion 141c. ing.

  The bearing 142 is a disk-roller-like rolling element, and a plurality of each are provided in each flange portion 141c. Here, five bearings 142 are provided in one row in one flange portion 141c, and five are provided in one row in the other flange portion 141c. The row of bearings 142 provided on one flange portion 141c and the row of bearings 142 provided on the other flange portion 141c are substantially parallel to each other, that is, the direction in which the bearings are arranged, that is, the row of bearings 142. The direction along is the moving direction when moving the hoisting machine 6 along the horizontal direction. The moving mechanism 140 is provided with a plate-like stopper 141e (see FIGS. 7 and 8, etc.) on one end side of each row of the bearings 142.

  The moving mechanism 140 configured as described above is arranged on each bearing 142 provided on the flange portion 141c of the moving table 141 in a state where the moving table 141 is rotatably supported by the rotating table 131 of the rotating mechanism 130. The hoisting machine 6 is placed via a rectangular plate-shaped machine bed 13 or the like (see FIGS. 2, 4, 6, etc.). The hoisting machine 6 is fixed to the upper surface of the machine bed 13 in the vertical direction. When the machine bed 13 and the hoisting machine 6 are placed on the moving mechanism 140, the stopper 141e abuts against the end surface of the machine bed 13 so that the hoisting machine 6 and the like can be prevented from falling off. When the hoisting machine 6 is pushed in the horizontal direction by an operator or the like, the moving mechanism 140 rolls with the bearings 142 in contact with the machine bed 13, so that the hoisting machine 6 is moved together with the machine bed 13. Can be smoothly moved in a direction along the row of bearings 142.

  The rotating mechanism 130 according to the present embodiment supports the hoisting machine 6 together with the moving mechanism 140 so as to be rotatable at the lifting position and the installation position with the rotation axis X (see FIG. 6) as the rotation center. . The rotating mechanism 130 can rotate the hoisting machine 6 together with the moving mechanism 140 along the horizontal direction between the lifting position and the installation position. The lifting position and the installation position are located at a predetermined rotation angle with respect to the rotation axis X. 9 and 10 illustrate a state in which the hoisting machine 6 is in the lifting position together with the moving mechanism 140, and FIGS. 11 and 12 illustrate a state in which the hoisting machine 6 together with the moving mechanism 140 is in the installation position. It is shown. 9 and 11 are views of the rotating mechanism 130 and the like viewed from below.

  The lifting position shown in FIGS. 9, 10, etc. is typically the position at which the hoisting machine 6 is lifted toward the machine beam 11 installed in the upper part of the hoistway 2. More specifically, the lifting position is indicated by the hoisting machine 6 during the process of lifting the hoisting machine 6 toward the machine beam 11 as represented by the hoisting machine 6 illustrated by a solid line in FIG. Is a position that does not interfere with articles such as the scaffolding 12 in the hoistway 2, in other words, a retreat position in which the hoisting machine 6 is retreated from the space side where the car 3 moves up and down in the hoistway 2. .

  The installation positions shown in FIGS. 11 and 12 are typically positions at which the hoisting machine 6 is installed on the machine beam 11 (positions that are substantially in the same direction as the installed state). More specifically, the installation position is determined by the hoisting machine 6 when the hoisting machine 6 is lifted toward the machine beam 11 as represented by the hoisting machine 6 illustrated by a two-dot chain line in FIG. It is a position that can interfere with articles such as the scaffold 12 in the hoistway 2, in other words, a protruding position in the hoistway 2 that projects the hoisting machine 6 toward the space where the car 3 moves up and down. .

  Then, as shown in FIG. 10 and the like, the rotating mechanism 130 is configured such that the plate-shaped stopper 131a formed on the rotating table 131 contacts the moving table 141 of the moving mechanism 140 at the lifting position. Rotation to the side opposite to the installation position side is restricted. Further, as shown in FIG. 9 and the like, the rotating mechanism 130 is configured such that, at the lifting position, bolts are inserted into the fixing holes 131b and the fixing holes 131c formed in the rotating table 131 and the bolts are moved to the moving table 141. As a result, the movable table 141, the machine bed 13, and the hoisting machine 6 can be positioned at the lifting position. On the other hand, as shown in FIG. 11 and the like, the rotation mechanism 130 has bolts inserted into the fixing holes 131d and the fixing holes 131e formed in the rotating base 131, which are different from the fixing holes 131b and 131c, at the installation position. At the same time, the bolt is fastened to the moving table 141, so that the moving table 141, the machine bed 13, and the hoisting machine 6 can be positioned at the installation position. In the rotation mechanism 130 of the present embodiment, the angle formed by the horizontal center axis of the hoisting machine 6 at the lifting position and the horizontal center axis of the hoisting machine 6 at the installation position, in other words, between the lifting position and the installation position. Is set to, for example, about 70 ° to 90 °, here about 80 °.

  As shown in FIG. 2 and the like, the fall prevention guide 150 guides the horizontal movement of the machine bed 13 and the hoisting machine 6 placed on the moving mechanism 140. The fall prevention guide 150 is provided, for example, on the turntable 131 or the like, and along the flange portion 141c on both sides of the flange portion 141c of the moving stand 141 in a state where the hoisting machine 6 is in the installation position together with the moving mechanism 140. Provided. The fall prevention guide 150 guides the horizontal movement while contacting the end surface of the machine bed 13 when the machine bed 13 placed on the moving mechanism 140 and the hoisting machine 6 are horizontally moved.

  As shown in FIG. 2, the slide mechanism 160 receives the hoisting machine 6 that is fixed to the machine beam 11 and moved in the horizontal direction from the moving mechanism 140, and the received hoisting machine 6 is transferred to the machine beam. 11 is mounted so as to be movable along the horizontal direction up to the upper part of 11. The slide mechanism 160 is configured to include a slide base, a bearing, and the like. Here, the slide mechanism 160 has substantially the same configuration as the moving mechanism 140 (not shown). However, the slide mechanism 160 has a slide base fixed to the machine beam 11. The slide mechanism 160 is opposed to the moving mechanism 140 in the horizontal direction with the rail guide frame 110 in the uppermost position, and also includes a row of bearings 142 of the moving mechanism 140 in the installation position and the slide mechanism 160. It is provided so as to have a positional relationship such that the row of bearings is continuous. In the state where the moving mechanism 140 is in the installation position, the positional relationship is such that the end opposite to the stopper 141e faces the slide mechanism 160, and the slide mechanism 160 is opposite to the stopper 141e of the moving mechanism 140. The machine bed 13 and the hoisting machine 6 can be received from the end of the machine.

  Next, the hoisting machine installation method will be described with reference to the flowchart of FIG. 13 and the perspective views of FIGS. FIG. 13 is a flowchart for explaining a hoist installation method using the hoist lifting jig unit according to the first embodiment. 14, FIG. 15, FIG. 16, FIG. 17, FIG. 18 and FIG. 19 are schematic perspective views for explaining a hoisting machine installation method using the hoisting machine lifting jig unit according to the first embodiment. This hoisting machine installation method includes a hoisting machine lifting method in which the hoisting machine 6 is lifted to the height of the machine beam 11 using the hoisting machine lifting jig unit 100 described above. In the hoisting machine installation method described below, the guide rail 7, guide rail 8, machine beam 11, etc. are basically installed, but the car 3 and the counterweight 4 are still installed. It is done in a state that is not done. In this state, as described above, in the elevator 1, various articles such as the scaffold 12 are temporarily installed in the hoistway 2 in the space in which the car 3 moves up and down. Moreover, about each structure of the hoisting machine lifting jig unit 100, FIGS. 2-12 may be referred suitably.

  First, the worker assembles the rail guide frame 110, the rotating mechanism 130, the moving mechanism 140, and the like as a jig assembling step (step ST1). In this case, for example, the worker assembles the rail guide frame 110 between the pair of guide rails 8 in the vicinity of the lowermost portion in the vertical direction in the hoistway 2. At this time, the worker may perform work by temporarily fixing the rail guide frame 110 to the guide rail 8 using the fixing blanket 120, for example. Further, the worker may use a support work such as a single pipe 14 (see FIG. 14 or the like) that supports the lower side of the rail guide frame 110 in the vertical direction. Thereafter, the worker fixes the rotating mechanism 130 to the upper part of the rail guide frame 110 by bolt fastening or the like, and further installs the moving mechanism 140 on the upper part of the rotating table 131 of the rotating mechanism 130.

  Next, the worker places the hoisting machine 6 on the upper part of the moving mechanism 140 after the jig assembling step (step ST1) as the placing step (step ST2). In this case, since the rail guide frame 110 is temporarily supported by the fixing blanket 120, the operator uses the electric hoist 170 b that is not currently connected to the rail guide frame 110 to use the hoisting machine 6. Is moved onto the moving table 141 of the moving mechanism 140. At this time, the hoisting machine 6 is in a state in which the machine bed 13 is fastened to the lower part, and the worker places the hoisting machine 6 on the moving table 141 together with the machine bed 13. Thereafter, the worker connects the electric lifting machine 170b and the like to the connecting portion 111 of the rail guide frame 110 as shown in FIG. In the example of FIG. 14, the hoisting machine 6 is illustrated as being placed on the moving mechanism 140 in a state where the moving mechanism 140 is in the installation position for ease of work, but is not limited thereto. The hoisting machine 6 may be placed on the moving mechanism 140 while the moving mechanism 140 is in the lifting position.

  Next, as a first positioning step, the worker positions the hoisting machine 6 at the lifting position together with the moving mechanism 140 after the placing step (step ST2) (step ST3). In this case, the worker rotates the moving mechanism 140, the machine bed 13, and the hoisting machine 6 in the installation position integrally to the lifting position side, thereby rotating them in the horizontal direction to the lifting position side. When the worker rotates the moving mechanism 140, the machine bed 13, and the hoisting machine 6 to the lifting position, the worker inserts bolts into the fixing holes 131 b and 131 c formed in the rotating table 131 and moves the moving table 141 and By fastening, the moving base 141, the machine bed 13, and the hoisting machine 6 are positioned at the lifting position.

  Next, as shown in FIG. 15, the operator lifts the hoisting machine 6 toward the machine beam 11 together with the rail guide frame 110 after the first positioning process (step ST3), as shown in FIG. Step ST4). In this case, the worker lifts the movable platform 141, the machine bed 13, and the hoisting machine 6 to the vicinity of the machine beam 11 by using, for example, an electric lifting machine 170b. Overlap.
