  An assembly apparatus 1 according to the first embodiment is an assembly apparatus for a guide rail 100 that is used to install a guide rail 100 for guiding an elevator board in a hoistway. The description will be given with reference. The guide rail 100 is configured by connecting a plurality of rail segments 101 together. Each rail segment 101 is fixed to the inner wall of the hoistway by a rail bracket each time it is connected.

  As shown in FIG. 1, the assembling apparatus 1 simultaneously mounts a plurality of rail segments 101 that are connected upward in order from the lowest part of the hoistway as guide rails 100 for each of the pair of guide rails 100. An assembly apparatus 1 shown in FIG. 1 includes an upper scaffold 2, a slide rail 3, and a slider 4.

  The upper scaffold 2 is installed on a saddle frame 200 provided on the elevator. The eaves frame 200 is assembled at an early stage in elevator installation so that it can be used as a part of a mobile scaffold for mounting various devices arranged in the hoistway. The eaves frame 200 includes at least an upper beam 201, a pair of vertical frames 202, a lower beam 203, and a guide device 204. An eyepiece is attached to the central portion of the upper beam 201, and a winch wire rope prepared for suspending the frame 200 from the hoistway is connected.

  The upper scaffold 2 is temporarily installed on the upper beam 201 only during the installation work of the elevator. As shown in FIG. 1, the upper scaffold 2 has a handrail 21 on the outer periphery that is slightly higher than the height of the waist of the worker working on it.

  As shown in FIG. 1, the slide rail 3 extends along the outer periphery of the upper scaffold 2 at a position higher than the handrail 21. As shown in FIG. 2, the slide rail 3 is disposed so as to pass outside the corner of the upper scaffold 2 and pass through the vicinity of the track of the guide rail 100. As shown in FIG. 2, the slide rail 3 has a start end portion 31 and a terminal end portion 32 that extend toward the inside of the upper scaffold 2. The cross-sectional shape of the slide rail 3 is constant from the start portion 31 to the end portion 32, and has a vertical wall 33 formed vertically and a rib 34 extending horizontally from the vertical wall 33 toward the inside of the upper scaffold 2. is doing. As shown in FIG. 2, the slide rail 3 is fixed to the upper scaffold 2 at three locations, ie, near the start end 31, near the end 32, and around the corner of the upper scaffold 2.

  A plurality of sliders 4 are mounted on the slide rail 3 as shown in FIG. 2, and the flanges 102 of the rail segments 101 are fixed so as to hold the rail segments 101 outside the upper scaffold 2 as shown in FIGS. Is done. As shown in FIGS. 3 and 4, the slider 4 includes a side roller 41, an inclined roller 42, an arm 43, and a block 44. The side roller 41 is in rolling contact with the side surface of the vertical wall 33 of the slide rail 3. The inclined roller 42 is in rolling contact with the corner formed by the vertical wall 33 and the rib 34 of the slide rail 3. The arm 43 swings about the rotation axis of the side roller. The block 44 integrally holds the side roller 41, the inclined roller 42, and the arm 43.

  Since the cross-sectional shape of the slide rail 3 is constant, the slider 4 is mounted from the start end 31 of the slide rail and removed from the end 32 as shown in FIG. As shown in FIG. 3, the slider 4 is merely in rolling contact with the slide rail 3 by the side roller 41 and the inclined roller 42, and can be extracted upward. When the start end portion 31 and the end end portion 32 of the slide rail 3 are connected endlessly, the slider 4 is circulated along the slide rail 3. In order to increase the number of the sliders 4, the sliders 4 may be inserted from above.

  The assembly apparatus 1 configured as described above has a pair of slide rails 3 and sliders 4 that are point-symmetric with respect to the center of the upper scaffold 2 as shown in FIG. I have. Hereinafter, the procedure for assembling the guide rail 100 will be described with reference to one side of the pair.

  The assembly apparatus 1 is moved to a place where the rail segment 101 carried into the hoistway is temporarily placed. In the assembling apparatus 1, a number of sliders 4 corresponding to the number of rail segments 101 to be mounted simultaneously are mounted from the start end 31 of the slide rail 3 as shown in FIG. 5. In the rail segment 101, the wire rope W of the lifting device is connected by the shackle S using the connection hole provided in the flange 102 at the upper end.

  The rail segment 101 lifted by the lifting device is fixed to the arm 43 of the slider 4 with a bolt as shown in FIG. At this time, each rail segment 101 is fixed to the slider 4 such that the upper end 103 is lower than the line of sight of the worker standing on the upper scaffold 2. Thereby, the worker of the upper scaffold 2 can attach or remove the wire rope to the upper end of the rail segment 101.

  In addition, the wire rope W of the lifting device that is operated to lift the rail segment 101 simply goes back and forth between the time when the rail segment 101 is temporarily placed and the time when the rail segment 101 is fixed to the slider 4. . Therefore, the time for operating the lifting device can be minimized. In order to adjust the position when the rail segment 101 is fixed to the slider 4, a chain block may be inserted between the wire rope W and the rail segment 101.

  The slider 4 to which the rail segment 101 is attached is sequentially sent to the end portion 32 side as shown in FIG. As shown in FIG. 1, when all the rail segments 101 to be mounted at a time are fixed, the assembly apparatus 1 is moved to a position where the upper end 100U of the guide rail 100 being assembled is lower than the line of sight of the worker standing on the upper scaffold 2. Raise. At this position, as shown in FIG. 7, a lifting device is attached to the upper end 103 of the first rail segment 101A held by the first slider 4A that has been moved to the vicinity of the guide rail 100 among the plurality of rail segments 101. The wire ropes W are connected. Since the upper end 103 of the rail segment 101 is lower than the line of sight of the worker on the upper scaffold, the work of connecting the wire rope W can be performed easily.

  When the wire rope W is connected, the bolt that has fixed the first rail segment 101A to the arm 43 of the slider 4 is removed. By operating the lifting device, the lower end 104 of the first rail segment 101A suspended by the wire rope W is raised to the upper end 100U of the guide rail 100 as shown in FIG. Then, the lower end 104 of the first rail segment 101A is connected to the upper end 100U of the guide rail 100. Since the assembling apparatus 1 is positioned so that the upper end 100U of the guide rail 100 is lower than the line of sight of the worker standing on the upper scaffold 2, the operation of connecting the first rail segment 101A to the guide rail 100 can be easily performed. .

  In order to fix the connected first rail segment 101A to the hoistway, the assembling apparatus 1 is raised to the height of the rail bracket corresponding to the first rail segment 101A. After the first rail segment 101A is fixed to the rail bracket, the upper end 103 of the first rail segment 101A is moved in the same manner as the assembly apparatus 1 is lifted to connect the first rail segment 101A to the guide rail 100. The assembling apparatus 1 is raised to a height that is lower than the line of sight of the worker standing on the upper scaffold 2. Since the wire rope W remains attached to the upper end 103 of the first rail segment 101A, it is removed and held by the second slider 4B moved to the vicinity of the guide rail 100 among the plurality of rail segments 101. The wire rope W is replaced with the upper end 103 of the second rail segment 101B.

  The first rail segment 101A is a part of the guide rail 100 assembled in the hoistway when the wire rope W is removed. The second rail segment 101B is in the same state as the first rail segment 101A shown in FIG. 7 when the wire rope W is connected. Therefore, the series of operations performed on the first rail segment 101A is performed on the second rail segment 101B in the same manner, and this series of operations is performed on all the rail segments 101 mounted on the assembly apparatus 1. repeat.

  As described above, the assembly apparatus 1 reduces the number of times of reciprocation from the point where the rail segment 101 is temporarily placed to the upper end 100U of the guide rail 100 by mounting a plurality of rail segments 101 at a time. In addition, after connecting the first rail segment 101A to the guide rail 100, the operation of replacing the wire rope W with the next second rail segment 101B can be performed without changing the height of the assembly device 1.

  If the lower end of the rail segment is placed on a mounting platform provided on the lower scaffolding that is installed at the same height as the riding floor, the upper end of the rail segment will be far above the line of sight of the worker standing on the upper scaffolding. If the upper end of the rail segment does not reach from the upper scaffold, a wire rope is attached to the middle part of the rail segment. However, the upper ends of the wire rope and the rail segment come into contact with each other and are damaged, which is not preferable.

  If this assembly apparatus 1 is used, the wire rope W can be hung on the upper end 103 of the rail segment 101, and the position of the assembly apparatus 1 does not need to be changed when the next rail segment 101 is replaced. The arm 43 of the slider 4 has a structure that rotates with respect to the block 44. Therefore, the slider 4 from which the rail segment 101 has been removed can be guided to the end portion 32 of the slide rail 3 by rotating the arm 43 to a position where it does not interfere with the guide rail 100, or lifted upward as it is. Can be easily removed. Therefore, there is no hindrance for setting up the next rail segment 101. By sequentially guiding the slider 4 mounted on the slide rail 3 to the vicinity of the guide rail 100, the rail segments 101 can be assembled one after another.

  In addition, the assembly apparatus 1 in 1st Embodiment is provided with the lower scaffold 5 in the position corresponded to the saddle bed of riding. A handrail 51 is provided on the lower scaffold 5, and it is possible for an operator to assist the lower ends 104 of the rail segments 101 so as not to contact each other when the slider 4 is moved.

  The assembly apparatus 1 of 2nd Embodiment is demonstrated with reference to FIGS. 9-13. The configuration of the assembly apparatus 1 of the second embodiment is the same as the configuration of the assembly apparatus 1 of the first embodiment, and the assembly method of the guide rail 100 according to the method of using this apparatus is different. Accordingly, components having the same configuration and function as those of the assembly device 1 of the first embodiment are denoted by the same reference numerals in each drawing, and detailed description thereof is omitted.

  The assembly apparatus 1 of the second embodiment has a higher position for attaching the rail segment 101 to the slider 4 as shown in FIG. 9 than in the case of the first embodiment. Specifically, the rail segment 101 is fixed to the slider 4 at such a height that the position at which the rail bracket is attached to the rail segment 101 is within a range where a worker standing on the upper scaffold 2 can reach. This operation is performed using the lifting device as shown in FIG. 6 of the first embodiment. The work of attaching or removing the wire rope W of the lifting device to or from the upper end 103 of the rail segment 101 is performed on a scaffold provided on the hoistway side or a stepladder installed on the upper scaffold 2. A simple lifting device such as a chain block is suspended from the handrail 21 of the upper scaffold 2, and a hook of the lifting device is hung on a jig that is attached using the connecting hole at the lower end 104 of the rail segment 101. It may be lifted. Moreover, you may lift using the rail bracket attached to the rail segment 101. FIG.

  As shown in FIG. 9, in the assembly apparatus 1 on which a plurality of rail segments 101 are mounted, the lower end 104 of the rail segment 101 held by the slider 4 is higher than the upper end 100U of the guide rail 100 being assembled in the hoistway. Is raised to. The first rail segment 101A held by the first slider 4A moved to the vicinity of the guide rail 100 among the plurality of rail segments 101 is rotated by the arm 43 of the first slider 4A as shown in FIG. By moving it, the guide rail 100 is placed on the track.

  This assembly apparatus 1 makes it possible to place the rail segment 101 on the track of the guide rail 100 without interfering with the vertical frame 202 of the collar frame 200 by rotating the rail segment 101 by the arm 43. Yes. If the slide rail 3 extends on the side of the guide rail 100 toward the inside of the upper scaffold 2, the arm 43 may not be rotated. In that case, since the slide rail 3 protrudes to the outside of the upper scaffold 2, a sufficient space is required between the inner wall of the hoistway and the upper scaffold.

  In the assembly apparatus 1, the lower end 104 of the mounted rail segment 101 is positioned higher than the upper end 100 </ b> U of the guide rail 100. Therefore, the slider 4 is guided along the slide rail 3 to the position where the rail segment 101 is held on the track of the guide rail 100 and the arm 43 is rotated as shown in FIG. The lower end 104 of the rail segment 101 is disposed so as to coincide with the upper end 100U of the guide rail 100.

  The rail segment 101 is fixed to the slider 4 so that the position at which the rail bracket is attached falls within the reach of the operator of the upper scaffold 2. Therefore, as shown in FIG. 10, the first rail segment 101A arranged on the track of the guide rail 100 is fixed to the inner wall of the hoistway by the rail bracket. The first rail segment 101A is supported by the guide rail 100 and is held by a rail bracket. The first rail segment 101A fixed by the rail bracket is removed from the first slider 4A. At this time, when the hand reaches the connecting portion between the lower end 104 of the first rail segment 101A and the upper end 100U of the guide rail 100 from the lower scaffold 5, the connecting tool may be temporarily fixed.

  The first slider 4A removed from the first rail segment 101A rotates the arm 43 to a position parallel to the slide rail 3, as shown in FIG. Since the arm 43 does not interfere with the first rail segment 101A, the first slider 4A can be extracted from the end portion 32 of the slide rail 3 as shown in FIG.

  After the first slider 4A is removed from the first rail segment 101A, the first slider 4A reaches the lower arm 104 of the first rail segment 101A and the upper arm 100U of the guide rail 100 within a range where the worker's hand in the upper scaffold 2 can reach. Then, the assembling apparatus 1 is lowered to connect the first rail segment 101A to the guide rail 100. The first rail segment 101 </ b> A becomes a part of the guide rail 100 by being connected to the guide rail 100.

  Then, the assembling apparatus 1 is raised to a position where the lower end 104 of the rail segment 101 held by the slider 4 is higher than the upper end 103 of the first rail segment 101A that is newly part of the guide rail 100. As a result, in order to connect the first rail segment 101A to the guide rail 100, the assembly apparatus 1 is raised. For the second rail segment 101B held by the second slider 4B that has moved the series of operations performed on the first rail segment 101A to the vicinity of the guide rail 100 among the plurality of rail segments 101 To implement. This series of operations is repeated for all rail segments 101 mounted on the assembly apparatus 1.

  As described above, according to the method for assembling the guide rail 100 using the assembling apparatus 1 according to the second embodiment, the operation of joining the rail segment 101 to the upper end 100U of the guide rail 100 without using the lifting device is performed. Can be implemented. Since the labor of raising and lowering the wire rope of the lifting device and replacing the wire rope can be saved, the work of assembling the guide rail 100 is simplified.

  In this specification, the “worker” is assumed to be a standard physique of an adult male, and therefore, the worker's line of sight is assumed to be approximately 150 cm from the floor of the scaffold. Moreover, the structure of the handrail 21 is not limited to what was shown in FIG.1 and FIG.9. Any structure may be used as long as it satisfies safety standards as a handrail for scaffolding for aerial work.

  If the slider 4 of the assembly apparatus 1 of the first and second embodiments described above has a function of holding the flange 102 of the rail segment 101 and moving along the slide rail 3, the side roller 41 and The present invention is not limited to being composed of the inclined roller 42, the arm 43, and the block 44. Similarly, the shape of the slide rail 3 is also shown in the first and second embodiments if it has a function of suspending a plurality of rail segments 101 via the slider 4 and smoothly guiding the slider 4. The shape is not limited.

  For example, the slider 4 includes a grooved upper wheel that fits to the upper edge of the vertical wall 33 of the slide rail 3 and a grooved lower wheel that fits to the lower edge of the vertical wall 33. It may be configured to move along. Further, for example, the slide rail 3 may be installed so as to cross the tip side of the blade of the guide rail 100 instead of being installed so as to go around the corner of the upper scaffold 2. Furthermore, the slide rail 3 does not need to protrude outward beyond the outer periphery of the upper scaffold 2 as shown in FIG. That is, the slide rail 3 extends along the inside of the outer periphery of the upper scaffold 2, and if the rail segment 101 is attached to the arm of the slider 4 projecting outside the upper scaffold 2, the rail segment 101 becomes the upper scaffold 2. It will be held outside.

  In the first and second embodiments described above, it is sufficient that at least the upper scaffold 2 is provided as a scaffold using the riding saddle frame 200. When the lower scaffold 5 is provided, the same slide rail 3 and slider 4 equipped on the upper scaffold 2 may be installed on the lower scaffold 5 to hold the lower part of the rail segment 101. In this case, the slider 4 to which the lower portion of the rail segment 101 is fixed may not have a strength that supports the weight of the rail segment 101. Therefore, the slider 4 may employ a mechanism for gripping the flange 102 of the rail segment 101 or a mechanism for attracting with a magnet, instead of passing the bolts and fixing them.

  Furthermore, in the first and second embodiments, by fixing the slider 4 to the rail segment 101 to which the rail bracket for fixing the connecting bracket for connecting the rail segments 101 to each other and the rail bracket for fixing to the hoistway is fixed, It is also expected to simplify the operation of connecting the rail segment 101 to the upper end 100U of the guide rail 100.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
