Description

The present disclosure relates to a hoisting machine positioning template and a method of installing a hoisting machine structure using the template.

As described in Patent Document 1, the hoisting machine of an elevator is generally a machine room at the upper part of a building in a state of being integrated with a hoisting machine stand, a sorase car, and a plurality of anti-vibration rubbers. Is fixed to. Against such a background, when the hoisting machine structure in which the hoisting machine, the hoisting machine stand, the sorase car, and a plurality of anti-vibration rubbers are integrated is replaced for the remodeling, a new one after the remodeling is used. The structure of the hoisting machine structure may be different from the old hoisting machine structure before remodeling, and it may not be easy to identify the fixing positions of the plurality of anti-vibration rubbers of the new hoisting machine structure. In such a case, conventionally, a new hoisting machine structure is fixed to the machine room as follows.

That is, in the state where the new hoisting machine structure is assembled, the index weight is fixed to the tip of each of the two ropes hanging vertically downward from each of the hoisting machine and the sorase wheel. Next, with the assembled hoisting machine structure suspended by a chain block or the like, the horizontal position of one index weight fixed to the tip of one rope is approximately the horizontal alignment position of the balance weight. The hoisting machine structure is moved horizontally until they match and the horizontal position of the other index weight fixed to the tip of the other rope substantially matches the horizontal alignment position of the basket.

After that, the horizontal position of one index weight substantially coincides with the horizontal alignment position of the balance weight, and the horizontal position of the other index weight substantially coincides with the horizontal alignment position of the basket. By fixing a plurality of anti-vibration rubbers to the machine room, the hoisting machine structure is fixed to the machine room.

Japanese Unexamined Patent Publication No. 2011-46481

Since the hoisting machine has a weight of about 500 kg even if it is light, in the above-mentioned hoisting machine structure method, the hoisting machine structure which is a heavy object suspended by a chain block or the like must be moved in the horizontal direction. Therefore, there is a risk that a disaster may occur due to the work of moving heavy objects, and the physical burden on the workers is heavy. In addition, the accuracy of mounting the hoisting machine structure in the machine room greatly depends on the experience and skill of the worker.

Therefore, an object of the present disclosure is to install a hoisting machine structure in each stage easily, safely and with high precision, a hoisting machine positioning template, and a method for installing the hoisting machine structure using the template. Is to provide.

In order to solve the above problems, the hoisting machine positioning template according to the present disclosure sets the installation position of the hoisting machine structure when installing the hoisting machine structure including the hoisting machine and a plurality of anti-vibration rubbers. It is a hoisting machine positioning template used for positioning, and the plurality of anti-vibration rubbers are attached in a relative positional relationship substantially the same as the relative positional relationship of the plurality of anti-vibration rubbers in the hoisting machine structure. The plurality of possible anti-vibration rubber mounting portions and the plurality of anti-vibration rubbers when the positions of the plurality of anti-vibration rubbers in the hoisting machine structure are used as reference positions in a state where the hoisting machine structure is used. The rope relative position of the two rope portions extending downward in the vertical direction from the hoisting machine structure with respect to the position of the vibration rubber sets the reference position from the position of the plurality of vibration isolation rubbers to the plurality of vibration isolation rubber attachment portions. It is provided with a rope position specifying portion that can be specified with respect to the positions of the plurality of attached anti-vibration rubbers when the positions of the plurality of attached anti-vibration rubbers are changed.

In all hoisting machine structures, the rope relative positions of the two ropes extending vertically downward from the hoisting machine structure with respect to the plurality of anti-vibration rubbers in the hoisting machine structure are uniquely determined. Therefore, if a plurality of anti-vibration rubbers in the hoisting machine structure can be precisely fixed at the installation position in the machine room, the horizontal positions of the two ropes extending downward in the vertical direction and parallel to the vertical direction can also be accurately positioned.

In such a background, according to the present disclosure, a plurality of anti-vibration rubbers may be attached to the hoisting machine positioning template with substantially the same relative positional relationship as the relative positional relationship of the plurality of anti-vibration rubbers in the hoisting machine structure. In that state, the rope position identification part can be used as a hoisting machine positioning template so that the rope position is relative to the rope relative to the multiple anti-vibration rubbers attached to the multiple anti-vibration rubber attachment parts. Two ropes can be positioned relative to each other. Further, with the index weight attached to the tip of each of the two positioned ropes, the hoisting machine positioning template is moved in the horizontal direction, and the horizontal position of one index weight is adjusted to the balance weight position. It is also possible to adjust so that the horizontal position of the other index weight substantially coincides with the horizontal position of the cage position adjusting portion while substantially matching the horizontal position of the portion. Therefore, the index weights attached to each of the two ropes are attached to the hoisting machine positioning template in a state where they match the horizontal alignment position of the balance weight and the horizontal alignment position of the basket. By simply fixing multiple anti-vibration rubbers in the machine room, multiple anti-vibration rubbers can be fixed in a predetermined position in the machine room with high accuracy, and by extension, the installation position is uniquely determined for multiple anti-vibration rubbers. The upper machine structure can also be fixed in a predetermined position in the machine room with high accuracy.

In other words, the hoisting machine structure can be fixed to the installation position with high accuracy simply by moving the hoisting machine positioning template, which is lighter and easier to move in each stage compared to the hoisting machine structure, in the horizontal direction. Unlike this, there is no risk of disasters associated with heavy object moving work, and the physical burden on workers can be significantly reduced. Furthermore, the hoisting machine structure can be fixed to the installation position with high accuracy simply by moving the hoisting machine positioning template, which is lighter and easier to move in each stage compared to the hoisting machine structure, in the horizontal direction. It is also possible to substantially prevent or prevent the mounting accuracy from fluctuating due to experience and skill. Therefore, the hoisting machine structure can be easily installed at each stage, and can be safely and highly precisely performed.

Further, in the hoisting machine positioning template of another aspect according to the present disclosure, when the hoisting machine structure includes a hoisting machine and a plurality of anti-vibration rubbers, the plurality of hoisting machines with respect to the hoisting machine. It is a hoisting machine positioning template capable of positioning the installation position of the hoisting machine structure with respect to each of the plurality of hoisting machine structures having different relative positions of the anti-vibration rubber, and is included in the plurality of hoisting machine structures. For any of the hoisting machine structures, a plurality of anti-vibration rubbers to which the plurality of anti-vibration rubbers can be attached have substantially the same relative positional relationship as the relative positional relationship of the plurality of anti-vibration rubbers in the hoisting machine structure.

FIG. 2 is a plan view of the template 50 to which a plurality of anti-vibration rubbers 20A are attached in the hoisting machine structure of the model A when viewed from above in the thickness direction.

The template 50 can be used for installing the hoisting machine structure of model A and installing the hoisting machine structure of model B. As shown in FIG. 2, the template 50 includes a frame member 55 as an example of the first member and a rod member 60 as an example of the second member. The rod member 60 preferably has a flat plate shape, but does not have to have a flat plate shape. The frame member 55 has a substantially rectangular shape at the outer edge 56, and has a through hole 57 having a substantially rectangular plan view at the center thereof. The center of the outer edge 56 substantially coincides with the center of the through hole 57.

The direction (shown as the Y direction in FIG. 2) coincides with the longitudinal direction of the through hole 57.

The rod member 60 can be fixed to the frame member 55 in two different arrangements. Specifically, with respect to the pair of widthwise extending portions 61a and 61b extending in the width direction of the frame member 55, the upper end surface of one of the widthwise extending portions 61a in the thickness direction (shown as the Z direction in FIG. 2). Two screw holes 62A and 62B are provided in the 65a at intervals in the width direction, and two screw holes 63A and 63B are also provided in the upper end surface 65b in the thickness direction of the other width direction extending portion 61b. It is provided at intervals in the width direction. The screw holes 62A face the screw holes 63A at intervals in the longitudinal direction of the frame member 55, and the screw holes 62B face the screw holes 63B at intervals in the longitudinal direction of the frame member 55.

On the other hand, the rod member 60 extends linearly, and the length of the rod member 60 is longer than the length of the through hole 57 in the longitudinal direction. Further, the rod member 60 has a first screw hole (through hole) at one end in the extending direction and a second screw hole (through hole) at the other end in the extending direction. When viewed from the Z direction, the first screw 67 is placed on the upper side of the frame member 55 so that the first screw hole overlaps the screw hole 62A and the second screw hole overlaps the screw hole 63A. , The rod member 60 is tightened into the first screw hole and the screw hole 62A from the upper side of the rod member 60, and the second screw 68 is tightened into the second screw hole and the screw hole 63A from the upper side of the rod member 60. It can be fixed to the frame member 55 in the first arrangement (hereinafter referred to as A arrangement), and the first structure (hereinafter referred to as A structure) can be configured. Bolts may be used as the first and first screws 67,68, and bolts may be used as the screws in the other screws described below.

Similarly, when viewed from the Z direction, the rod member 60 is arranged above the frame member 55 so that the first screw hole overlaps the screw hole 62B and the second screw hole overlaps the screw hole 63B. The first screw 67 is tightened into the first screw hole and the screw hole 62B from the upper side of the rod member 60, and the second screw 68 is tightened into the second screw hole and the screw hole 63B from the upper side of the rod member 60. The rod member 60 can be fixed to the frame member 55 in a second arrangement (hereinafter referred to as B arrangement), and a second structure (hereinafter referred to as B structure) can be configured.

The template 50 is used in the A structure when installing the hoisting machine structure of the model A. Further, the template 50 is used in the B structure when the installation work of the hoisting machine structure of the model B is performed. As shown in FIG. 2, the frame member 55 has two sets of anti-vibration rubber mounting portions 71A and 71B around its four corners, and the rod member 60 is sandwiched between the first and second screw holes. The region has two sets of rope positioning portions 72A and 72B.

In this embodiment, each of the anti-vibration rubber mounting portion 71A and the anti-vibration rubber mounting portion 71B is composed of a screw hole (through hole), and the rope position specifying portion 72A is composed of two notches 73A and 74A. The rope position specifying portion 72B is composed of two notches 73B and 74B.

Next, the relationship between the A structure of the template 50 and the hoisting machine structure of the model A will be described. As described above, in the case of the hoisting machine structure of model A, the relative positions of all parts other than the hoisting machine with respect to the hoisting machine are the same within the range of the difference due to the tolerance. Therefore, in the case of the hoisting machine structure of the model A, the relative positions of the ropes with respect to the plurality of anti-vibration rubbers also match within the range of the difference due to the tolerance. Against this background, in the structure A, a plurality of anti-vibration rubbers in the hoisting machine structure of the model A are attached to the plurality of anti-vibration rubber attachment portions 71A in the template 50, and two notches 73A in the rope position specifying portion 72A. A model attached to the template 50 for two rope parts that hang vertically downward in parallel from the two notches 73A and 74A in the rope when the rope is passed through each of the 74A and 74A. The relative positions of the plurality of anti-vibration rubbers in the hoisting machine structure of A are a part of the rope hanging vertically downward from the hoisting machine due to gravity in the hoisting machine structure of model A and the model A. Range of difference due to tolerance in the relative positions of multiple anti-vibration rubbers in the hoisting machine structure of model A with respect to a part of the rope hanging vertically downward from the sorase wheel in the hoisting machine structure in parallel in the vertical direction due to gravity. It is designed to match within.

Similarly, regarding the hoisting machine structure of the model A and the hoisting machine structure of the model B having a significantly different structure, the plurality of anti-vibration rubber mounting portions 71B in the template 50 and the plurality of hoisting machine structures of the model B are similarly formed. When the anti-vibration rubber is attached and the rope is passed through each of the two notches 73B and 74B in the rope positioning portion 72B, the two notches 73B and 74B in the rope are vertically downward due to gravity. The relative positions of the plurality of anti-vibration rubbers in the model B hoisting machine structure attached to the template 50 with respect to the two rope portions hanging in parallel are vertically downward from the hoisting machine due to gravity in the model B hoisting machine structure. Model B hoisting machine structure for a part of the rope hanging parallel to the vertical direction and a part of the rope hanging vertically downward from the Sorase wheel due to gravity in the hoisting machine structure of model B The relative positions of the plurality of anti-vibration rubbers in the above are matched within the range of the difference due to the tolerance.

Next, a method of installing the hoisting machine structure of the model A using the template 50 will be described with reference to FIG. In FIG. 3, the template 50 is simplified and drawn in comparison with FIG. 2, and some screw holes and the like are not shown. Further, since the installation method of the hoisting machine structure of the model B is the same as the installation method of the hoisting machine structure of the model A, the description thereof will be omitted.

With reference to FIG. 3, first, the template 50 has an A structure, and then a plurality of anti-vibration rubbers 20A having a hoisting machine structure of model A are fixed to a plurality of anti-vibration rubber attachment portions 71A of the template 50. This fixing is performed using, for example, a screw hole constituting the vibration-proof rubber mounting portion 71A, a screw hole provided in the vibration-proof rubber 20A, and a screw.

Next, the rope position specifying portion 72A for aligning the balance weight is attached to the first rope portion 77 to which the first index weight 76 used as an index for adjusting the position of the balance weight is attached to the tip portion. A rope position specifying portion 72A for aligning the basket with the second rope portion 79 to which the second index weight 78 used as an index for adjusting the position of the basket position is attached to the tip portion through the notch 74A. Pass the notch 73A.

Subsequently, the horizontal position (position on the horizontal plane, which is a two-dimensional plane) of the first index weight 76 fixed to the tip of the first rope portion 77 is set to the balance weight position adjusting portion provided at the bottom of the hoistway. While matching the horizontal position of (not shown), the horizontal position of the second index weight 78 fixed to the tip of the second rope portion 79 is set to the basket position adjusting portion (not shown) provided at the bottom of the hoistway. Match the horizontal position of). This operation is executed by moving the template 50 in the horizontal direction. Each of the balance weight position adjusting portion and the basket position adjusting portion is composed of, for example, protruding portions protruding vertically upward from the bottom of the hoistway in substantially parallel to the vertical direction.

As the first rope portion 77, one side portion of the rope wound around the hoisting machine or the sorase wheel in the hoisting machine structure of the model A to be installed may be used, and the second rope portion 79 may be used. The other side portion of the rope wound around the hoisting machine or the sorase car in the hoisting machine structure of the model A to be installed may be used. In this case, since the length of the rope hanging from the template 50 can be easily adjusted, the two index weights are attached to the balance weight position adjustment unit and the basket position adjustment unit regardless of the height of the building where the elevator is installed. The work of aligning can be easily performed.

Next, the horizontal position of the first index weight 76 coincides with the horizontal position of the balance weight position adjusting portion, and the horizontal position of the second index weight 78 coincides with the horizontal position of the basket position adjusting portion. Further, in a state where the thickness direction of the template 50 is substantially the same as the vertical direction, a plurality of anti-vibration rubbers 20A of the model A integrated with the template 50 are integrated with the template 50. Fix it in the machine room with. Regarding the hoisting machine structure of model A, the horizontal position of the tip of the rope part on the balance weight fixing side that hangs vertically downward from the machine room in the vertical direction due to gravity is the balance weight position adjustment part. The horizontal position of the tip of the rope part on the fixed side of the basket, which hangs vertically downward from the machine room due to gravity in parallel with the vertical direction, is adjusted to the horizontal position of the basket. When the position matches the horizontal position of the portion, the horizontal position of one end of the rope is set to the horizontal position of the rope fixing position 91 of the balance weight 90 which is arranged so that the hoistway can be raised and lowered normally. It can be matched, and the horizontal position of the other end of the rope can be matched with the horizontal position of the rope fixing position 93 of the basket 92 which is arranged so that the hoistway can be raised and lowered normally. Therefore, if the plurality of anti-vibration rubbers 20A are fixed in this way, one end of the rope hanging from the hoisting machine structure of the model A whose arrangement position is uniquely determined for the plurality of anti-vibration rubbers 20A can be caught. It can be fixed at a predetermined position on the weight, and the other end of the rope hanging from the hoisting machine structure of Model A can be fixed at a predetermined position on the basket.

After that, the template 50 is removed from the plurality of vibration-proof rubbers 20A fixed in the machine room, and parts other than the plurality of vibration-proof rubbers 20A in the hoisting machine structure of the model A are attached to the plurality of vibration-proof rubbers 20A. The installation of the model A hoisting machine structure in the room is completed.

In this installation method, the tip of the first rope portion 77 coincides with the horizontal position of the balance weight position adjusting portion, and the tip of the second rope portion 79 coincides with the horizontal position of the balance weight position adjusting portion. It is in a state. Therefore, as is clear from the explanation so far, the balance weight is arranged so that the horizontal position of one end of the rope of the hoisting machine structure of model A installed in the machine room can be normally raised and lowered in the hoistway. It is possible to match the horizontal position of the rope fixing position 91 of 90, one end of the rope can be fixed to the rope fixing position 91, and further, the rope of the hoisting machine structure of model A installed in the machine room. The horizontal position of the other end can be matched with the horizontal position of the rope fixing position 93 of the basket 92 which is arranged so that the hoistway can be raised and lowered normally, and the other end of the rope is set to the rope fixing position 93. Can be fixed.

As described above, when the hoisting machine structure 1 includes the hoisting machine 15 and the plurality of anti-vibration rubbers 20, the relative positions of the plurality of anti-vibration rubbers 20 with respect to the hoisting machine 15 are different from each other. It is a template that can position the installation position of the hoisting machine structure for each of a plurality of hoisting machine structures (the hoisting machine structure of model A and the hoisting machine structure of model B). Further, for any of the hoisting machine structures included in the plurality of hoisting machine structures, the plurality of anti-vibration rubbers have substantially the same relative positional relationship as the relative positional relationship of the plurality of anti-vibration rubbers 20A in the hoisting machine structure. A plurality of anti-vibration rubber attachment portions 71A to which the rubber 20A can be attached, and a plurality of anti-vibration rubber 20A positions in the hoisting machine structure as reference positions in the state where the hoisting machine structure is used. The relative position of the ropes of the two rope portions extending downward in the vertical direction from the hoisting machine structure with respect to the position of the anti-vibration rubber 20A sets the reference position to the position of the plurality of anti-vibration rubbers 20A in the hoisting machine structure. Rope position specifying portion 72A that can be specified with respect to the positions of the plurality of vibration-proof rubbers 20A attached when the positions are changed to the positions of the plurality of vibration-proof rubbers 20A attached to the plurality of vibration-proof rubber mounting portions 71A. And exists.

For example, in the above embodiment, the case where the template 50 can be used for installing two different types of hoisting machine structures has been described. However, the template of the present disclosure may only be used for the installation of only one hoisting machine structure. Alternatively, the template of the present disclosure may have a structure having three or more sets of a plurality of preventive rubber mounting portions and a rope position specifying portion, and may be used for installing three or more hoisting machine structures different from each other.

That is, the template of the present disclosure may be used to position the installation position of the hoisting machine structure when installing the hoisting machine structure including the hoisting machine and a plurality of anti-vibration rubbers. Further, the template of the present disclosure includes a plurality of anti-vibration rubber attachment portions capable of attaching the plurality of anti-vibration rubbers in substantially the same relative positional relationship as the relative positional relationship of the plurality of anti-vibration rubbers in the hoisting machine structure. , Vertically downward from the hoisting machine structure with respect to the positions of the plurality of anti-vibration rubbers when the positions of the plurality of anti-vibration rubbers in the hoisting machine structure are used as the reference position in the state where the hoisting machine structure is used.

The number of models of the hoisting machine structure in which the template can be positioned may be any number of 1 or more, as long as it is provided with a rope position specifying portion that can be specified with respect to the positions of the plurality of vibration-proof rubbers. ..

Further, the template changes the fixed position of the second member (bar member 60) with respect to the first member (frame member 55) to change the relative stationary position of the second member with respect to the first member. , The relative position of the rod member 60 in the width direction with respect to the frame member 55 was changed. However, by providing two or more sets of fixing portions (for example, screw holes (through holes)) for fixing the frame member on the rod member, the relative position of the rod member in the longitudinal direction with respect to the frame member may also be changed.

Further, by changing the fixed position of the second member (bar member 60) with respect to the first member (frame member 55), the relative stationary position of the second member with respect to the first member is changed, but the auto-lock type Any known slide mechanism, such as the slide mechanism used in the cutter knife, may be used to change the relative stationary position of the second member with respect to the first member.

Further, the case where the template 50 includes the first member and the second member and the relative stationary position of the second member with respect to the first member can be changed has been described. However, the template of the present disclosure may be composed of only one integral member, or may be composed of one integral member and a fastening member such as a screw. That is, the main body of the template including all the anti-vibration rubber mounting portions and all the rope position specifying portions may be composed of only one integral member.

In addition, the template includes a plurality of different sets composed of a plurality of anti-vibration rubber mounting portions and a rope position specifying portion, and there is a set corresponding to any of the hoisting machine structures included in the plurality of hoisting machine structures. However, one or more anti-vibration rubber attachment parts are used in two or more different sets, and one or more rope position specifying parts are used in two or more different sets. At least one may be satisfied.

In this way, the hoist positioning template can be used to install multiple hoist structures and is stylish with a small number of at least one of the plurality of anti-vibration rubber attachments and rope positioning parts. It may be anything.

Further, a case where the rope position specifying portion 72A is composed of two notches 73A and 74A through which the two ropes can pass has been described. However, the rope position specifying portion does not have to be a notch, and may be formed of, for example, a through hole. Further, as shown in FIG. 4, the rope position specifying portion 172 may have a locking portion 174, and the hoisting machine structure is positioned by using the index weight jig 130 dedicated to positioning. You may.

FIG. 4A is a schematic cross-sectional view of a portion around the rope position specifying portion 172 in the template 150 of the modified example for explaining such an embodiment, and FIG. 4B is a structure of an index weight jig. 4 (c) is a diagram showing a rope position specifying portion 172 to which the index weight jig 130 is attached.

Will be done. Further, as shown in FIG. 4B, the index weight jig 130 has a metal annular member 131 and a rope 133 to which the index weight 132 is fixed at the tip. The length of the rope 133 is long enough to be applied to tall buildings. The length of the index weight jig 130 can be adjusted by adjusting the fixed position (locking position) of the rope 133 to the annular member 131. It is preferable that the rope 133 is provided with a scale indicating the length from the index weight 132 so that the length of the rope 133 can be easily adjusted. Further, the rope may be a rope used in an elevator or a rope not used in an elevator. Further, instead of the rope, a string member that is lighter and more flexible than the rope used in the elevator may be used. As shown in FIG. 4C, at the time of positioning work, after appropriately adjusting the length of the index weight jig 130, the annular member 131 is substantially orthogonal to the thickness direction of the template 150 at the locking portion 174. The rope 133 of the index weight jig 130 is locked in the locking portion 174a extending in the direction of the index weight jig 130 so as to pass through the through hole 173. In this way, the positioning work of the hoisting machine structure can be executed with a simple structure. The rope or string member may be directly attached to the locking portion 174a without using the annular member. Further, even when a string member is used, a specific portion (composed of a marker or the like) capable of specifying the length from the index weight may be attached to the string member.
