Description

Template for positioning tractor and method for setting tractor structure using same

Technical Field

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

Background

As described in patent document 1, a hoisting machine of an elevator is generally fixed to a machine room located in an upper part of a building in a state of being integrated with a hoisting machine base, a deflector sheave, and a plurality of vibration-proof rubbers. In such a background, conventionally, when a hoisting machine structure in which a hoisting machine, a hoisting machine base, a deflector sheave, and a plurality of vibration-proof rubbers are integrated is replaced for modification, the structure of a new hoisting machine structure after modification may be different from the old hoisting machine structure before modification, and the fixing positions of the plurality of vibration-proof rubbers of the new hoisting machine structure may not be easily determined. In such a case, conventionally, a new hoisting machine structure is fixed to a machine room as follows.

That is, in a state where the new hoisting machine structure is assembled, the index weight is fixed to the respective terminal portions of the 2 ropes respectively hanging downward in the vertical direction from the hoisting machine and the deflector sheave. Next, the assembled hoisting machine structure is suspended by a chain block or the like, and the hoisting machine structure is moved in the horizontal direction until the horizontal position of one index counterweight fixed to the distal end portion of one rope substantially coincides with the horizontal position of the counterweight, and the horizontal position of the other index counterweight fixed to the distal end portion of the other rope substantially coincides with the horizontal position of the car.

Then, the plurality of vibration-proof rubbers are fixed to the machine room in a state where the horizontal position of one index counterweight substantially coincides with the horizontal alignment position of the counterweight and the horizontal position of the other index counterweight substantially coincides with the horizontal alignment position of the car, thereby fixing the hoisting machine structure to the machine room.

Disclosure of Invention

Problems to be solved by the invention

Since the hoisting machine has a weight of about 500kg even if it is light, in the method of the above-described hoisting machine structure, 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, a disaster may occur due to the movement of the heavy object, and the physical load on the operator may be large. In addition, the accuracy of mounting the hoisting machine structure to the machine room depends largely on the experience and skill of the operator.

Therefore, an object of the present disclosure is to provide a hoist positioning template that can be particularly easily implemented and that can implement the installation of a hoist structure safely and with high accuracy, and a hoist structure installation method using the template.

Means for solving the problems

In order to solve the above problem, a hoist positioning shoe according to the present disclosure is a hoist positioning shoe for positioning an installation position of a hoist structure including a hoist and a plurality of vibration-proof rubbers when the hoist structure is installed, the hoist positioning shoe including: a plurality of rubber vibration insulators that are capable of being attached in a relative positional relationship that is substantially the same as the relative positional relationship of the plurality of rubber vibration insulators in the hoisting machine structure; and a rope position specifying unit that is capable of specifying the rope relative position with respect to the positions of the plurality of vibration-proof rubbers attached to the plurality of vibration-proof rubber attachment portions when the reference position is changed from the positions of the plurality of vibration-proof rubbers to the positions of the plurality of vibration-proof rubbers attached to the plurality of vibration-proof rubber attachment portions, regarding 2 rope portions extending downward in the vertical direction from the hoisting machine structure in a case where the positions of the plurality of vibration-proof rubbers in the hoisting machine structure are set as the reference positions in a state where the hoisting machine structure is used.

In all hoisting machine configurations, the relative positions of the 2 ropes extending vertically downward from the hoisting machine configuration with respect to the ropes of the plurality of vibration-proof rubbers in the hoisting machine configuration are uniquely determined. Therefore, if the plurality of vibration-proof rubbers in the hoisting machine structure can be precisely fixed to the installation position of the machine room, the horizontal positions of the 2 ropes extending vertically downward in parallel with the vertical direction can also be accurately positioned.

In this context, according to the present disclosure, the plurality of vibration-proof rubbers can be attached to the hoist positioning shoe in a relative positional relationship substantially equal to the relative positional relationship of the plurality of vibration-proof rubbers in the hoist structure, and in this state, the rope position determining unit can position the 2 ropes with respect to the hoist positioning shoe in the relative rope positions in the case where the plurality of vibration-proof rubbers attached to the plurality of vibration-proof rubber attachment portions are used as a reference. In addition, even when the template for positioning the hoisting machine is moved in the horizontal direction in a state where the index weights are attached to the respective distal end portions of the 2 ropes being positioned, the horizontal position of one of the index weights can be adjusted to substantially coincide with the horizontal position of the counterweight position adjusting portion, and the horizontal position of the other index weight can be adjusted to substantially coincide with the horizontal position of the car position adjusting portion. Therefore, by fixing the plurality of vibration-proof rubbers attached to the hoist positioning shoe to the machine room in a state where the index weights attached to the 2 ropes respectively coincide with the horizontal position of the counterweight and the horizontal position of the car, the plurality of vibration-proof rubbers can be fixed to the predetermined positions of the machine room with high accuracy, and the hoist structure whose installation position is uniquely determined with respect to the plurality of vibration-proof rubbers can be fixed to the predetermined positions of the machine room with high accuracy.

That is, the hoist positioning template, which is light and easy to move compared with the hoist structure, can be moved in the horizontal direction to fix the hoist structure to the installation position with high accuracy, so that unlike the conventional method, there is no fear of occurrence of a disaster accompanying the heavy object moving work, and the burden of the physical strength of the operator can be reduced significantly. Further, since the hoisting machine structure can be fixed to the installation position with high accuracy only by moving the hoisting machine positioning template, which is extremely lightweight and easy to move as compared with the hoisting machine structure, in the horizontal direction, it is possible to substantially prevent or prevent the mounting accuracy from varying depending on the experience or skill of the operator. Therefore, the installation of the hoisting machine structure can be performed particularly easily, and the installation of the hoisting machine structure can be performed safely and with high accuracy.

In addition, in a case where a hoisting machine structure is configured to include a hoisting machine and a plurality of vibration-proof rubbers, a hoisting machine positioning template according to another aspect of the present disclosure is capable of positioning an installation position of the hoisting machine structure for each of a plurality of hoisting machine structures whose relative positions of the plurality of vibration-proof rubbers with respect to the hoisting machine are different from each other, and the hoisting machine positioning template includes: a plurality of rubber vibration insulators attached to the hoisting machine structure so as to be capable of being attached in a relative positional relationship substantially equal to a relative positional relationship of the plurality of rubber vibration insulators in the hoisting machine structure; and a rope position specifying unit that is capable of specifying the rope relative position with respect to the positions of the plurality of vibration-proof rubbers attached to the plurality of vibration-proof rubber attachment portions when the reference position is changed from the positions of the plurality of vibration-proof rubbers to the positions of the plurality of vibration-proof rubbers attached to the plurality of vibration-proof rubber attachment portions, regarding 2 rope portions extending downward in the vertical direction from the hoisting machine structure in a case where the positions of the plurality of vibration-proof rubbers in the hoisting machine structure are set as the reference positions in a state where the hoisting machine structure is used.

According to the present disclosure, a hoist positioning template can be used for any of a plurality of different hoist configurations. Therefore, the versatility of the hoist positioning template can be improved.

In the hoist positioning shoe according to the another aspect, the hoist positioning shoe may include a plurality of different groups each including the plurality of vibration-proof rubber mounting portions and the rope position determining portion, the hoist positioning shoe may have the corresponding group for any of the hoist configurations included in the plurality of hoist configurations, and the hoist positioning shoe may satisfy at least one of a case where the hoist positioning shoe has the plurality of vibration-proof rubber mounting portions of 1 or more groups among the 2 or more different groups and a case where the hoist positioning shoe has the rope position determining portion of 1 or more groups among the 2 or more different groups.

According to this configuration, at least one of the case where the plurality of vibration-proof rubber mounting portions of 1 group or more are shared among different groups of 2 groups or more and the case where the rope position specifying portion of 1 group or more is shared among different groups of 2 groups or more is satisfied. Therefore, the hoist positioning template can be used to install a plurality of hoist structures, and at least one of the plurality of vibration-proof rubber attachment portions and the rope position determining portion can be formed in a fashionable structure with a small number.

In the hoist positioning shoe according to the present disclosure, the hoist positioning shoe may include a first member and a second member, the plurality of vibration-proof rubber attachment portions may be provided on the first member, the rope position determining portion may be provided on the second member, and a relative rest position of the second member with respect to the first member may be changed.

According to this configuration, there are a plurality of sets of the vibration-proof rubber mounting portions and the rope position determining portions corresponding to a plurality of hoisting machine configurations, and a particularly light hoisting machine positioning shoe can be realized.

In the present disclosure, the first member may be a frame member having an outer edge with a substantially rectangular shape when viewed in a thickness direction, and the second member may be a bar member that is attachable to a plurality of positions in a width direction of the frame member in a state of being substantially parallel to a longitudinal direction of the frame member.

According to this configuration, there are a plurality of sets of the vibration-proof rubber mounting portions and the rope position determining portion, and an extremely light hoist positioning shoe can be formed simply and inexpensively.

In the present disclosure, the rope position determining portion may be 2 slits through which 2 ropes can pass.

According to this configuration, the rope position determining unit can be formed simply and inexpensively, and the rope can be easily attached to and detached from the rope position determining unit.

In addition, a method of installing a hoisting machine structure according to the present disclosure uses the hoisting machine positioning template according to any one of claims 1 to 6, and includes: a rubber fixing step of fixing the plurality of vibration-proof rubbers of the hoisting machine structure to be set to the plurality of vibration-proof rubber mounting portions of the hoisting machine positioning shoe corresponding to the hoisting machine structure to be set; a rope extending step of causing, by using the rope position determining portion, relative positions of the plurality of vibration-proof rubbers attached to the plurality of vibration-proof rubber attachment portions with respect to portions of the 2 ropes having the index weights attached to respective distal end portions thereof, which portions hang vertically downward in parallel with the vertical direction, to substantially coincide with relative positions of the plurality of vibration-proof rubbers in the hoisting machine structure with respect to portions of the 2 rope portions hanging vertically downward in parallel with the vertical direction from the hoisting machine structure; a template moving step of moving the hoisting machine positioning template in a horizontal direction after the rope extending step so that a horizontal position of the index counterweight attached to one of the 2 ropes substantially coincides with a horizontal position of a counterweight, and a horizontal position of the index counterweight attached to the other of the 2 ropes substantially coincides with a horizontal position of a car; a rubber stationary part fixing step of fixing the plurality of vibration-proof rubbers to a stationary part stationary with respect to a building in a state where a horizontal position of the index weight attached to the one rope substantially coincides with a horizontal position to be aligned with the counterweight, a horizontal position of the index weight attached to the other rope substantially coincides with a horizontal position to be aligned with the car, and a thickness direction of the hoisting machine positioning formwork substantially coincides with a vertical direction after the formwork moving step; a template removing step of removing the hoisting machine positioning template from the plurality of vibration-proof rubbers after the rubber stationary portion fixing step; and a structure fixing step of fixing, after the template removing step, a structure other than the plurality of vibration-proof rubbers in the hoisting machine structure to the plurality of vibration-proof rubbers fixed to the stationary portion.

Detailed Description

Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. In addition, when a plurality of embodiments, modifications, and the like are included below, it is initially assumed that a new embodiment is constructed by appropriately combining these features. In the following embodiments, the same components are denoted by the same reference numerals in the drawings, and redundant description thereof is omitted. In addition, the drawings include schematic drawings, and the dimensional ratios of the members such as the vertical, horizontal, and height are not necessarily uniform between different drawings. Among the constituent elements described below, those not recited in the independent claims representing the uppermost concept are arbitrary constituent elements and are not essential constituent elements.

Fig. 1 is a front view of a hoisting machine structure 1 provided in a machine room 80 located on an upper side of a hoistway of an elevator. As shown in fig. 1, the machine room 80 includes a floor portion 51 and a base 52 fixed to the floor portion 51, and the hoisting machine structure 1 is provided on the base 52. The base 52 is made of, for example, H steel or I steel.

The hoisting machine structure 1 includes a hoisting machine base 5, a deflector sheave 10, a hoisting machine 15, and a plurality of vibration-proof rubbers 20. The plurality of vibration-proof rubbers 20 are attached to the foundation 52, and the hoisting machine foundation 5 is integrated with the plurality of vibration-proof rubbers 20 by fixing predetermined positions thereof to the plurality of vibration-proof rubbers 20. The deflector sheave 10 is attached to the hoisting machine base 5 so as to be rotatable relative to the hoisting machine base 5 by fixing the center axis thereof to a predetermined position of the hoisting machine base 5. The hoisting machine 15 is integrated with the hoisting machine base 5 by fixing a predetermined position thereof to a predetermined position on the upper surface of the hoisting machine base 5.

If the machine type of the hoisting machine structure 1 is the same, the hoisting machine base 5, the deflector sheave 10, the hoisting machine 15, and the plurality of vibration-proof rubbers 20 are substantially the same. Here, substantially the same means that there is a difference in the extent of converging within the tolerance, but there is no larger difference (hereinafter, substantially the same is used in this meaning). In the hoisting machine structure 1, if the machine types are the same, the relative position of the hoisting machine base 5 to the hoisting machine 15, the relative position of the deflector pulley 10 to the hoisting machine 15, the relative positions of the plurality of vibration-proof rubbers 20 to the hoisting machine 15, and the relative positions of the plurality of vibration-proof rubbers 20 in the hoisting machine structure 1 are all substantially the same.

Therefore, in the hoisting machine structure 1, if the model is the same, the relative positions of the plurality of vibration-proof rubbers 20 with respect to the portion 25a of the rope 25 which hangs vertically downward from the deflector pulley 10 due to gravity in parallel with the vertical direction are substantially the same, and if the model is the same, the relative positions of the plurality of vibration-proof rubbers 20 with respect to the portion 25b of the rope 25 which hangs vertically downward from the hoisting machine 15 due to gravity in parallel with the vertical direction are also substantially the same.

Next, a hoisting machine positioning template 50 (hereinafter, simply referred to as a template 50) according to an embodiment of the present disclosure and a method of installing a hoisting machine structure using the template will be described. Fig. 2 is a plan view of a template 50 to which a plurality of vibration-proof rubbers 20A in the hoisting machine structure of model a are attached, as viewed from above in the thickness direction.

The template 50 can be used for installation of the hoisting machine configuration of model a and the hoisting machine configuration 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 bar member 60 as an example of the second member. The bar member 60 preferably has a flat plate shape, but may not have a flat plate shape. The outer edge 56 of the frame member 55 has a substantially rectangular shape, and a through hole 57 having a substantially rectangular shape in plan view is provided in the center of the frame member 55. The center of the outer edge 56 substantially coincides with the center of the through hole 57. The width direction of the outer edge 56, that is, the width direction of the frame member 55 (indicated as X direction in fig. 2) coincides with the width direction of the through hole 57, and the length direction of the outer edge 56, that is, the length direction of the frame member 55 (indicated as Y direction in fig. 2) coincides with the length direction of the through hole 57.

The rod member 60 can be fixed to the frame member 55 in 2 different arrangements. Specifically, with respect to the pair of width-direction extending portions 61a, 61B extending in the width direction of the frame member 55, 2

screw holes

62A, 62B are provided at intervals in the width direction on an upper end surface 65a in the thickness direction (indicated as Z direction in fig. 2) of one width-direction extending portion 61a, and 2

screw holes

63A, 63B are also provided at intervals in the width direction on an upper end surface 65B in the thickness direction of the other width-direction extending portion 61B. The screw hole 62A and the screw hole 63A are opposed to each other with a space therebetween in the longitudinal direction of the frame member 55, and the screw hole 62B and the screw hole 63B are opposed to each other with a space therebetween in the longitudinal direction of the frame member 55.

On the other hand, the rod member 60 linearly extends, and the length of the rod member 60 is longer than the length of the through hole 57 in the longitudinal direction. 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 the rod member 60 is disposed on the upper side of the frame member 55 such that the first screw hole and the screw hole 62A overlap each other and the second screw hole and the screw hole 63A overlap each other, the rod member 60 can be fixed to the frame member 55 in a first arrangement (hereinafter, referred to as an "arrangement a") by fastening the first screw 67 to the first screw hole and the screw hole 62A from the upper side of the rod member 60 and fastening the second screw 68 to the second screw hole and the screw hole 63A from the upper side of the rod member 60, and a first structure (hereinafter, referred to as an "arrangement a") can be configured. Further, as the first and

second screws

67 and 68, bolts may be used, and in other screws described below, bolts may be used.

Similarly, when the rod member 60 is disposed on the upper side of the frame member 55 such that the first screw holes and the screw holes 62B overlap and the second screw holes and the screw holes 63B overlap, the rod member 60 can be fixed to the frame member 55 in the second arrangement (hereinafter, referred to as the "B arrangement") by fastening the first screws 67 to the first screw holes and the screw holes 62B from the upper side of the rod member 60 and fastening the second screws 68 to the second screw holes and the screw holes 63B from the upper side of the rod member 60, and a second configuration (hereinafter, referred to as the "B configuration") can be configured.

The template 50 is used as the a configuration when the hoisting machine configuration of model a is installed. The template 50 is used as the component B when the hoisting machine of the model B is installed. As shown in fig. 2, the frame member 55 has 2 sets of a plurality of vibration-proof

rubber mounting portions

71A, 71B around its four corners, and the rod member 60 has 2 sets of rope

position determining portions

72A, 72B in a region sandwiched by the first screw hole and the second screw hole.

In the present embodiment, the vibration-proof rubber mounting portion 71A and the vibration-proof rubber mounting portion 71B are each constituted by a screw hole (through hole), the cord position determination portion 72A is constituted by 2

notches

73A, 74A, and the cord position determination portion 72B is constituted by 2

notches

73B, 74B.

Next, a relationship between the a configuration of the template 50 and the hoisting machine configuration of model a will be described. As described above, in the case of the hoist configuration of model a, the relative positions of all parts other than the hoist with respect to the hoist are matched within the range of the difference due to the tolerance. Therefore, in the case of the hoist structure of type a, the relative positions of the ropes with respect to the plurality of vibration-proof rubbers are also matched within the range of the difference due to the tolerance. In the configuration a, in the case where the plurality of vibration-proof rubbers in the model a hoisting machine structure are attached to the plurality of vibration-proof rubber attachment portions 71A in the template 50 and the ropes are passed through the 2

notches

73A and 74A in the rope position specifying portion 72A, respectively, the relative positions of the plurality of vibration-proof rubbers in the model a hoisting machine structure attached to the template 50 with respect to the 2 rope portions of the ropes hanging vertically downward from the 2

notches

73A and 74A due to gravity in parallel with the vertical direction coincide with the relative positions of a part of the ropes hanging vertically downward from the hoisting machine due to gravity in the model a hoisting machine structure and a part of the ropes hanging vertically downward from the deflector pulley due to gravity in the model a hoisting machine structure within a range of a difference caused by a tolerance.

Similarly, in the hoisting machine structure of model B, which is largely different from the hoisting machine structure of model a, the plurality of vibration-proof rubbers in the hoisting machine structure of model B are attached to the plurality of vibration-proof rubber attachment portions 71B in the template 50, and when the ropes are passed through the 2

notches

73B, 74B in the rope position determination portion 72B, respectively, the relative positions of the plurality of vibration-proof rubbers in the hoisting machine structure of model B attached to the template 50 with respect to the 2 rope portions hanging downward in the vertical direction from the 2

notches

73B, 74B in parallel with the vertical direction due to gravity are matched with the relative positions of the plurality of vibration-proof rubbers in the hoisting machine structure of model B with respect to a part of the ropes hanging downward in parallel with the vertical direction from the vertical direction to the vertical direction due to gravity in the hoisting machine structure of model B and a part of the ropes hanging downward in parallel with the vertical direction due to gravity in the hoisting machine structure of model B in a range of difference due to tolerance.

Next, a method of installing the hoist structure of model a using the template 50 will be described with reference to fig. 3. In fig. 3, the die plate 50 is simplified as compared with fig. 2, and some of the screw holes and the like are omitted. The method of installing the hoisting machine of model B is the same as that of model a, and therefore, the description thereof is omitted.

Referring to fig. 3, first, after the shoe 50 is configured as a, the vibration-proof rubbers 20A of the hoisting machine configuration of model a are fixed to the vibration-proof rubber mounting portions 71A of the shoe 50. This fixing is performed using, for example, a screw hole constituting the vibration isolation rubber mounting portion 71A, a screw hole provided in the vibration isolation rubber 20A, and a screw.

Next, the first rope portion 77 having the first index counterweight 76 attached to the distal end portion thereof for use as a position adjustment index of the counterweight position is passed through the notch 74A of the rope position determining portion 72A for performing the counterweight positioning, and the second rope portion 79 having the second index counterweight 78 attached to the distal end portion thereof for use as a position adjustment index of the car position is passed through the notch 73A of the rope position determining portion 72A for performing the car positioning.

Next, the horizontal position (position on the horizontal plane as a 2-dimensional plane) of the first index counterweight 76 fixed to the distal end portion of the first rope portion 77 is made to coincide with the horizontal position of a counterweight position adjustment portion (not shown) provided at the bottom of the hoistway, and the horizontal position of the second index counterweight 78 fixed to the distal end portion of the second rope portion 79 is made to coincide with the horizontal position of a car position adjustment portion (not shown) provided at the bottom of the hoistway. This action is performed by moving the template 50 in the horizontal direction. The counterweight position adjusting portion and the car position adjusting portion are each constituted by a projecting portion that projects substantially in parallel with the vertical direction upward in the vertical direction from the bottom of the hoistway, for example.

Further, as the first rope portion 77, one side portion of the rope wound around the hoisting machine or the deflector sheave in the hoisting machine configuration of model a to be installed may be used, and as the second rope portion 79, the other side portion of the rope wound around the hoisting machine or the deflector sheave in the hoisting machine configuration of model a to be installed may be used. In this case, since the length of the rope suspended from the template 50 can be easily adjusted, the operation of aligning the 2 index counterweights with the counterweight position adjusting part and the car position adjusting part can be easily performed regardless of the height of the building in which the elevator is installed.

Next, in a state where the horizontal position of the first index weight 76 coincides with the horizontal position of the counterweight position adjusting portion, the horizontal position of the second index weight 78 coincides with the horizontal position of the car position adjusting portion, and the thickness direction of the template 50 substantially coincides with the vertical direction, the plurality of vibration-proof rubbers 20A of the model a integrated with the template 50 are fixed to the machine room in a state integrated with the template 50. In the hoist structure of model a, when the horizontal position of the terminal end of the rope portion on the counterweight fixing side hanging down from the machine room to the lower side in the vertical direction in parallel with the vertical direction by gravity is in a state of being aligned with the horizontal position of the counterweight position adjusting portion, and the horizontal position of the terminal end of the rope portion on the car fixing side hanging down from the machine room to the lower side in the vertical direction in parallel with the vertical direction by gravity is in a state of being aligned with the horizontal position of the car position adjusting portion, the horizontal position of one end portion of the rope can be aligned with the horizontal position of the rope fixing position 91 of the counterweight 90 disposed to be able to normally ascend and descend in the hoistway, and the horizontal position of the other end portion of the rope can be aligned with the horizontal position of the rope fixing position 93 of the car 92 disposed to be able to normally ascend and descend in the hoistway. Therefore, if the plurality of vibration-proof rubbers 20A are fixed in this manner, one end portion of the rope hanging from the hoisting machine structure of model a, whose arrangement position is uniquely determined with respect to the plurality of vibration-proof rubbers 20A, can be fixed to a predetermined position of the counterweight, and the other end portion of the rope hanging from the hoisting machine structure of model a can be fixed to a predetermined position of the car.

Thereafter, the template 50 is removed from the plurality of vibration-proof rubbers 20A fixed to the machine room, and the parts other than the plurality of vibration-proof rubbers 20A in the model a hoisting machine structure are attached to the plurality of vibration-proof rubbers 20A, thereby completing installation of the model a hoisting machine structure in the machine room.

In this setting method, the terminal end of the first rope portion 77 and the horizontal position of the counterweight position adjusting member are aligned, and the terminal end of the second rope portion 79 and the horizontal position of the counterweight position adjusting member are aligned. Therefore, as is apparent from the description so far, the horizontal position of one end portion of the rope of the hoisting machine structure of model a installed in the machine room can be made to coincide with the horizontal position of the rope fixing position 91 of the counterweight 90 disposed so as to be able to normally ascend and descend in the hoistway, and the one end portion of the rope can be fixed to the rope fixing position 91, and further, the horizontal position of the other end portion of the rope of the hoisting machine structure of model a installed in the machine room can be made to coincide with the horizontal position of the rope fixing position 93 of the car 92 disposed so as to normally ascend and descend in the hoistway, and the other end portion of the rope can be fixed to the rope fixing position 93.

As described above, the template 50 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) in which the relative positions of the plurality of vibration-proof rubbers 20 with respect to the hoisting machine 15 are different when the hoisting machine structure 1 is configured to include the hoisting machine 15 and the plurality of vibration-proof rubbers 20. In addition, any hoisting machine configuration included in the plurality of hoisting machine configurations includes: a plurality of rubber vibration isolators 71A to which the plurality of rubber vibration isolators 20A can be attached in a relative positional relationship substantially identical to the relative positional relationship of the plurality of rubber vibration isolators 20A in the hoisting machine structure; and a rope position determining unit 72A configured to determine the rope relative position with respect to the positions of the plurality of vibration-proof rubbers 20A attached to the plurality of vibration-proof rubber attachment portions 71A when the rope relative positions of the 2 rope portions extending vertically downward from the hoisting machine structure with respect to the positions of the plurality of vibration-proof rubbers 20A in the hoisting machine structure are set as reference positions in a state where the hoisting machine structure is used, and when the reference positions are changed from the positions of the plurality of vibration-proof rubbers 20A in the hoisting machine structure to the positions of the plurality of vibration-proof rubbers 20A attached to the plurality of vibration-proof rubber attachment portions 71A.

According to the present disclosure, in each hoisting machine configuration, the plurality of antivibration rubbers 20A can be attached to the shoe 50 in a relative positional relationship substantially identical to the relative positional relationship of the plurality of antivibration rubbers 20A in the hoisting machine configuration, and in this state, the 2 ropes can be positioned with respect to the shoe 50 by the rope position determining portion 72A in the relative rope positions in the case where the plurality of antivibration rubbers 20A attached to the plurality of antivibration rubber attachment portions 71A are used as a reference. In addition, even when the template 50 is moved in the horizontal direction in a state where the

index weights

76 and 78 are attached to the respective distal end portions of the 2 positioned ropes, it is possible to adjust the horizontal position of one index weight 76 to substantially coincide with the horizontal position of the counterweight position adjusting portion, and the horizontal position of the other index weight 78 fixed to the distal end portion of the other rope to substantially coincide with the horizontal position of the car position adjusting portion. Therefore, the plurality of vibration-proof rubbers 20A attached to the template 50 can be fixed to the machine room with high accuracy only by fixing the plurality of vibration-proof rubbers 20A attached to the template 50 to the machine room in a state where the

index counterweights

76 and 78 attached to the 2 ropes respectively coincide with the position aligned in the horizontal direction of the car and the position aligned in the horizontal direction of the counterweight and the thickness direction of the template 50 substantially coincides with the vertical direction, and further, the hoisting machine structure whose installation position is uniquely determined with respect to the plurality of vibration-proof rubbers 20A can be fixed to the fixing position of the machine room with high accuracy.

That is, the hoist structure can be fixed to the installation position with high accuracy only by moving the template 50, which is extremely light in weight and easy to move in comparison with the hoist structure, in the horizontal direction, and therefore unlike the conventional method, there is no fear of occurrence of a disaster accompanying the heavy object moving work, and the burden of the physical strength of the operator can be extremely reduced. Further, since the hoisting machine structure can be fixed to the installation position with high accuracy only by moving the template 50, which is extremely light in weight and easy to move in comparison with the hoisting machine structure, in the horizontal direction, it is possible to substantially prevent or prevent the mounting accuracy from varying depending on the experience and skill of the operator. Therefore, the installation of the hoisting machine structure can be performed particularly easily, and the installation of the hoisting machine structure can be performed safely and with high accuracy. In addition, since the template 50 can be used for any of a plurality of different hoisting machine configurations, the versatility of the template 50 can be improved.

The template 50 may be provided with a frame member (first member) 55 and a rod member (second member) 60, the plurality of vibration-proof rubber attachment portions 71A may be provided on the frame member (first member) 55, and the rope position determination portion 72A may be provided on the rod member 60. Further, the relative rest position of the rod member 60 with respect to the frame member 55 may be changed.

According to this configuration, the template 50 can be provided with a plurality of sets of the vibration-proof

rubber mounting portions

71A and 71B and the rope

position determining portions

72A and 72B corresponding to a plurality of hoisting machine configurations. Further, since the relative rest position of the rod member 60 with respect to the frame member 55 can be changed, the form 50 can be formed with a particularly light weight as compared with a case where forms that can be used in the same plural hoisting machine configurations are formed integrally.

The first member may be a frame member 55 having a substantially rectangular shape when viewed from the thickness direction, and the second member may be a bar member 60 that can be attached to the frame member 55 at a plurality of positions in the width direction of the frame member 55 in a state substantially parallel to the longitudinal direction of the frame member 55.

According to this configuration, a plurality of sets of the vibration-proof

rubber mounting portions

71A and 71B and the rope

position determination portions

72A and 72B can be provided, and the mold 50 can be formed to be extremely light in a simple and inexpensive manner.

In the present disclosure, the rope

position determining portions

72A and 72B may be 2

notches

73A, 73B, 74A, and 74B through which 2 ropes can pass.

With this configuration, the rope

position determining units

72A and 72B can be formed simply and inexpensively, and the ropes can be easily attached to and detached from the rope

position determining units

72A and 72B.

The method of installing the hoisting machine structure according to the present disclosure is a method of installing a hoisting machine structure using the template 50. In addition, the setting method of the tractor structure of the present disclosure includes the following rubber fixing steps: the plurality of vibration-proof rubbers 20A of the hoisting machine structure to be set are fixed to the plurality of vibration-proof rubber mounting portions 71A of the shoe corresponding to the hoisting machine structure to be set.

In addition, the method for installing the traction machine structure of the present disclosure includes the following rope extending steps: by using the rope position determining portion 72A, the relative positions of the plurality of vibration-proof rubbers 20A attached to the plurality of vibration-proof rubber attachment portions 71A with respect to the

portions

77a, 79a of the 2

rope portions

77, 79 having the

index weights

76, 78 attached to the respective distal end portions thereof, which portions hang vertically downward and parallel to the vertical direction, are made to substantially coincide with the relative positions of the plurality of vibration-proof rubbers 20A in the hoisting machine structure with respect to a portion of each of the 2 rope portions hanging vertically downward and parallel to the vertical direction from the hoisting machine structure.

In addition, the setting method of the tractor structure of the present disclosure includes the following template moving steps: after the rope extending step, the template 50 is moved in the horizontal direction so that the horizontal position of the first index counterweight 76 of the first rope portion 77 attached to the 2

rope portions

77, 79 substantially coincides with the horizontal alignment position of the counterweight 90 (counterweight position adjusting portion), and the horizontal position of the second index counterweight 78 of the second rope portion 79 attached to the 2

rope portions

77, 79 substantially coincides with the horizontal alignment position of the car 92 (car position adjusting portion).

In addition, the method for setting the tractor structure of the present disclosure includes the following rubber static part fixing step: after the formwork moving step, the plurality of vibration-proof rubbers 20A are fixed to a stationary portion (for example, a machine room) that is stationary with respect to the building in a state where the horizontal position of the first index counterweight 76 attached to the first rope portion 77 substantially coincides with the horizontal position of the counterweight 90, the horizontal position of the second index counterweight 78 attached to the other second rope portion 79 substantially coincides with the horizontal position of the car 92, and the thickness direction of the formwork 50 substantially coincides with the vertical direction.

In addition, the setting method of the tractor structure comprises the following template dismounting steps: after the rubber stationary portion fixing step, the die plate 50 is detached from the plurality of vibration-proof rubbers 20A.

In addition, the setting method of the tractor structure of the present disclosure includes the following structure fixing steps: after the shoe removing step, the structures other than the plurality of vibration-proof rubbers 20A in the hoisting machine structure are fixed to the plurality of vibration-proof rubbers 20A fixed to the stationary portion.

According to the method for installing a hoisting machine structure of the present invention, the installation of the hoisting machine structure can be performed particularly easily, and the installation of the hoisting machine structure can be performed safely and with high accuracy.

The present disclosure is not limited to the above-described embodiments and modifications thereof, and various improvements and modifications can be made within the scope of the matters recited in the claims of the present application and their equivalents.

For example, in the above embodiment, a description has been given of a case where the template 50 can be used for installation of hoisting machine configurations of 2 different models. However, the template of the present disclosure may also be used for only 1 tractor configuration setup. Alternatively, the template of the present disclosure may have a configuration of a group including 3 or more sets of the rubber attachment prevention portions and the rope position determination portions, or may be used for installation of 3 or more hoisting machine configurations 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 the plurality of vibration-proof rubbers. In addition, the template of the present disclosure may include: a plurality of rubber vibration insulators to which the plurality of rubber vibration insulators can be attached in a relative positional relationship substantially the same as a relative positional relationship of the plurality of rubber vibration insulators in the hoisting machine structure; and a rope position specifying unit that specifies a rope relative position of 2 rope portions extending downward in the vertical direction from the hoisting machine structure with respect to positions of the plurality of vibration-proof rubbers when the hoisting machine structure is used and positions of the plurality of vibration-proof rubbers in the hoisting machine structure are set as reference positions, wherein the rope position specifying unit is capable of specifying the rope relative position with respect to the positions of the plurality of vibration-proof rubbers attached to the plurality of vibration-proof rubber attachment portions when the reference positions are changed from the positions of the plurality of vibration-proof rubbers to the positions of the plurality of vibration-proof rubbers attached to the plurality of vibration-proof rubber attachment portions, and the number of types of hoisting machine structures where the template can be positioned may be any number of 1 or more.

In the template, the relative rest position of the second member (rod member 60) with respect to the first member (frame member 55) is changed by changing the fixing position of the second member with respect to the first member, and more specifically, the relative position of the rod member 60 with respect to the frame member 55 in the width direction is changed. However, the relative position of the rod member with respect to the frame member in the longitudinal direction may also be varied by providing the rod member with 2 or more sets of fixing portions (e.g., screw holes (through holes)) for fixing the frame member.

Further, the relative stationary position of the second member with respect to the first member is changed by changing the fixed position of the second member (rod member 60) with respect to the first member (frame member 55), but any known sliding mechanism such as a sliding mechanism used for an automatic locking type cutting blade may be used to change the relative stationary position of the second member with respect to the first member.

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. However, the formwork of the present disclosure may be configured by only 1 integral member, or may be configured by 1 integral member and a fastening member such as a screw. That is, the main body of the form provided with all the vibration-proof rubber mounting portions and all the rope position determining portions may be formed of only 1 member integrally.

Further, the template may include a plurality of different groups each including a plurality of vibration-proof rubber mounting portions and a rope position specifying portion, and each of the hoisting machine configurations included in the plurality of hoisting machine configurations may include a corresponding group, and at least one of a case where the plurality of vibration-proof rubber mounting portions of 1 group or more are shared among 2 different groups or more and a case where the rope position specifying portion of 1 group or more is shared among 2 different groups or more may be satisfied.

In this way, the hoist positioning shoe can be used to install a plurality of hoist structures, and can be a fashionable structure in which at least one of the plurality of vibration-proof rubber attaching portions and the rope position determining portion is small in number.

The case where the rope position specifying unit 72A is configured by 2

notches

73A and 74A through which 2 ropes can pass is described. However, the rope position determining portion may not be a notch, and may be formed of a through hole, for example. As shown in fig. 4, the rope position determining unit 172 may have the locking unit 174, or may perform positioning work of the hoisting machine structure using the index counterweight attachment 130 dedicated to positioning.

Fig. 4 (a) is a schematic cross-sectional view of the periphery of the rope position specifying unit 172 in the template 150 according to the modification example described in the above embodiment, fig. 4 (b) is a diagram illustrating the configuration of the index weight aid, and fig. 4 (c) is a diagram illustrating the rope position specifying unit 172 to which the index weight aid 130 is attached.

As shown in fig. 4 (a), the rope position specifying portion 172 includes a through hole 173 and a substantially L-shaped locking portion 174, and the locking portion 174 is integrally formed with the main body 151 of the shoe 150. As shown in fig. 4 (b), the index weight assistive device 130 includes a metal ring member 131 and a rope 133 having a tip end portion to which the index weight 132 is fixed. The length of the rope 133 is a sufficient length that can be applied to a tall building as well. The length of the index weight assistive device 130 can be adjusted by adjusting the fixing position (locking position) of the rope 133 to the annular member 131. Preferably, the rope 133 is marked with a scale indicating the length from the index weight 132, and the length of the rope 133 is easily adjusted. The rope may be a rope used in an elevator or a rope not used in an elevator. Instead of the rope, a rope member that is lighter and more flexible than the rope used in the elevator may be used. As shown in fig. 4 (c), at the time of positioning operation, after the length of the index weight assistant 130 is appropriately adjusted, the annular member 131 is locked to a locking portion 174a of the locking portion 174 extending in a direction substantially perpendicular to the thickness direction of the template 150, and the rope 133 of the index weight assistant 130 passes through the through hole 173. Thus, the positioning work of the hoisting machine structure can be performed with a simple structure. Alternatively, the rope or the string member may be directly tied to the locking portion 174a without using a ring member. In the case of using the string member, a determination unit (constituted by a mark or the like) capable of determining the length of the distance index weight may be added to the string member.
